  • Approaching this case with ABDPDF

    - by Younes
    We have ABCPDF 8 available to work with for this case. We need to rebuild an existing PDF with markup and texts in it with text that comes from a CMS. What we basicly want to do is use an existing PDF and replace blocks of text and images with the ones our content editors specify in Sitecore. I have been looking at the documentation of ABCPDF but it's kind of overwelming at this point, cause it's the first time I'm trying to do anything with dynamically building a PDF. I found that it's possible to read text from an existing PDF document using the .GetText(""); method. This Method will accept 4 parameters and I've tried the SVG one (returns xml). When I load the xml in an XmlDocument I find that alot of textblocks which I assumed to be one block of text is split up in different parts. For example: <text xml:space="preserve" x="215.4312" y="48.9478" font-size="9" font-family="Arial-BoldMT" fill="rgb(237, 106, 0)" textLength="94.032" transform="translate(215.4312, 48.9478) translate(-215.4312, -48.9478)">wijkverpleegkundige?</text> <text xml:space="preserve" x="215.4312" y="61.9438" font-size="9" font-family="ArialMT" textLength="5.652" transform="translate(215.4312, 61.9438) translate(-215.4312, -61.9438)">&#8226;&#9;</text> <text xml:space="preserve" x="223.9362" y="61.9438" font-size="9" font-family="ArialMT" textLength="49.509" transform="translate(223.9362, 61.9438) translate(-223.9362, -61.9438)">Lichamelijke</text> <text xml:space="preserve" x="273.4452" y="61.9438" font-size="9" font-family="ArialMT" textLength="2.502" transform="translate(273.4452, 61.9438) translate(-273.4452, -61.9438)">&#9;</text> <text xml:space="preserve" x="275.9472" y="61.9438" font-size="9" font-family="ArialMT" textLength="32.013" transform="translate(275.9472, 61.9438) translate(-275.9472, -61.9438)">controle</text> <text xml:space="preserve" x="307.9602" y="61.9438" font-size="9" font-family="ArialMT" textLength="2.502" transform="translate(307.9602, 61.9438) translate(-307.9602, -61.9438)">&#9;</text> <text xml:space="preserve" x="310.4622" y="61.9438" font-size="9" font-family="ArialMT" textLength="10.008" transform="translate(310.4622, 61.9438) translate(-310.4622, -61.9438)">op</text> <text xml:space="preserve" x="320.4702" y="61.9438" font-size="9" font-family="ArialMT" textLength="2.502" transform="translate(320.4702, 61.9438) translate(-320.4702, -61.9438)">&#9;</text> <text xml:space="preserve" x="322.9722" y="61.9438" font-size="9" font-family="ArialMT" textLength="42.021" transform="translate(322.9722, 61.9438) translate(-322.9722, -61.9438)">bloeddruk,</text> <text xml:space="preserve" x="364.9932" y="61.9438" font-size="9" font-family="ArialMT" textLength="2.502" transform="translate(364.9932, 61.9438) translate(-364.9932, -61.9438)">&#9;</text> <text xml:space="preserve" x="223.9362" y="74.9398" font-size="9" font-family="ArialMT" transform="translate(223.9362, 74.9398) translate(-223.9362, -74.9398)" My first idea was to get all blocks of text and just replace them with my own text that comes from the CMS, but this doesn't seem to be the way to go. I'm now completely lost and don't know how to approach this issue. Is there any way to get the following XML to be accessible in objects in ABCPDF or am I doing things wrong? What will be the best approach on making this happen?

  • Can't display Tool Tips in VC++6.0

    - by Paul
    I'm missing something fundamental, and probably both simple and obvious. My issue: I have a view (CPlaybackView, derived from CView). The view displays a bunch of objects derived from CRectTracker (CMpRectTracker). These objects each contain a floating point member. I want to display that floating point member when the mouse hovers over the CMpRectTracker. The handler method is never executed, although I can trace through OnIntitialUpdate, PreTranslateMessage, and OnMouseMove. This is in Visual C++ v. 6.0. Here's what I've done to try to accomplish this: 1. In the view's header file: public: BOOL OnToolTipNeedText(UINT id, NMHDR * pNMHDR, LRESULT * pResult); private: CToolTipCtrl m_ToolTip; CMpRectTracker *m_pCurrentRectTracker;//Derived from CRectTracker 2. In the view's implementation file: a. In Message Map: ON_NOTIFY_EX(TTN_NEEDTEXT,0,OnToolTipNeedText) b. In CPlaybackView::OnInitialUpdate: if (m_ToolTip.Create(this, TTS_ALWAYSTIP) && m_ToolTip.AddTool(this)) { m_ToolTip.SendMessage(TTM_SETMAXTIPWIDTH, 0, SHRT_MAX); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_AUTOPOP, SHRT_MAX); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_INITIAL, 200); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_RESHOW, 200); } else { TRACE("Error in creating ToolTip"); } this->EnableToolTips(); c. In CPlaybackView::OnMouseMove: if (::IsWindow(m_ToolTip.m_hWnd)) { m_pCurrentRectTracker = NULL; m_ToolTip.Activate(FALSE); if(m_rtMilepostRect.HitTest(point) >= 0) { POSITION pos = pDoc->m_rtMilepostList.GetHeadPosition(); while(pos) { CMpRectTracker tracker = pDoc->m_rtMilepostList.GetNext(pos); if(tracker.HitTest(point) >= 0) { m_pCurrentRectTracker = &tracker; m_ToolTip.Activate(TRUE); break; } } } } d. In CPlaybackView::PreTranslateMessage: if (::IsWindow(m_ToolTip.m_hWnd) && pMsg->hwnd == m_hWnd) { switch(pMsg->message) { case WM_LBUTTONDOWN: case WM_MOUSEMOVE: case WM_LBUTTONUP: case WM_RBUTTONDOWN: case WM_MBUTTONDOWN: case WM_RBUTTONUP: case WM_MBUTTONUP: m_ToolTip.RelayEvent(pMsg); break; } } e. Finally, the handler method: BOOL CPlaybackView::OnToolTipNeedText(UINT id, NMHDR * pNMHDR, LRESULT * pResult) { BOOL bHandledNotify = FALSE; CPoint CursorPos; VERIFY(::GetCursorPos(&CursorPos)); ScreenToClient(&CursorPos); CRect ClientRect; GetClientRect(ClientRect); // Make certain that the cursor is in the client rect, because the // mainframe also wants these messages to provide tooltips for the // toolbar. if (ClientRect.PtInRect(CursorPos)) { TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR; CString str; str.Format("%f", m_pCurrentRectTracker->GetMilepost()); ASSERT(str.GetLength() < sizeof(pTTT->szText)); ::strcpy(pTTT->szText, str); bHandledNotify = TRUE; } return bHandledNotify; }

  • How to handle recurring dates (dates only) in .NET?

    - by Wayne M
    I am trying to figure out a good way to handle recurring events in .NET, specifically for an ASP.NET MVC application. The idea is that a user can create an event and specify that the event can occur repeatedly after a specific interval (e.g. "every two weeks", "once a month" and so on). What would be the best way to tackle this? My brainstorming right now is to have two tables: Job and RecurringJob. Job is the "master" record and has the description of the job as well a key to what customer it's for, while RecurringJob links back to Job and has additional info on what the occurrence frequency is (e.g. 1 for "once a month") as well as the timespan (e.g. "Weekly", "Monthly"). The issue is how to determine and set the next occurrence of the job since this will have to be something that's done regularly. I've seen two trains of thought with this: This logic should either be stored in a database column and periodically updated, or calculated on the fly in the code. Any thoughts or suggestions on tackling this? Edit: this is for a subscription based web app I'm creating to let service businesses schedule their common recurring jobs easily and track their customers. So a typical use might be to create a "Cut lawn" job for Mr Smith that occurs every month The exact date isn't important - it's the ability for the customer to see that Mr Smith gets his lawn cut every month and followup with him about it. Let me rephrase the above to better convey my idea. A sample use case for the application might be as follows: User pulls up the customer record for John Smith and clicks the Add Job link. The user fills out the form to create a job with a name of "Cut lawn", a start date of 11/15/2009, and selects a checkbox indicating that this job continually occurs. The user is presented with a secondary screen asking for the job frequency. The user indicates (haven't decided how at this point - let's assume select lists) that the job occurs once a month. User clicks save. Now, when the user views the record for John Smith, they can see that he has a job, "Cut lawn", that occurs every month starting from 11/15/2009. On the main dashboard when it's one week prior to the assumed start date, the user sees the job displayed with an indicator such as "12/15/2009 - Cut lawn (John Smith)". A week before the due date someone from the company calls him up to schedule and he says he's going to be out of town until 1/1/2010, so he wants his appointment rescheduled for that date. Our user can change the date for the job to be 1/1/2010, and now the recurrence will start one month from that date (e.g. next time will be 2/1/2010). The idea behind this is that the app is targeting businesses like lawn care, plumbers, carpet cleaners and the like where the exact date isn't as important (because it can and will change as people are busy), the key thing is to give the business an indicator that Mr. Smith's monthly service is coming up, and someone should give him a call to determine when exactly it can be scheduled for. In effect give these businesses a way to track repeat business and know when it's time to followup with a customer.

  • Android: Showing photos runs out of memory

    I'm using a dialog box to display images in my android project.

  • Is it safe to assert a functions return type?

    - by wb
    This question is related to this question. I have several models stored in a collection. I loop through the collection and validate each field. Based on the input, a field can either be successful, have an error or a warning. Is it safe to unit test each decorator and assert that the type of object returned is what you would expect based on the given input? I could perhaps see this being an issue for a language with function return types since my validation function can return one of 3 types. This is the code I'm fiddling with: <!-- #include file = "../lib/Collection.asp" --> <style type="text/css"> td { padding: 4px; } td.error { background: #F00F00; } td.warning { background: #FC0; } </style> <% Class UserModel Private m_Name Private m_Age Private m_Height Public Property Let Name(value) m_Name = value End Property Public Property Get Name() Name = m_Name End Property Public Property Let Age(value) m_Age = value End Property Public Property Get Age() Age = m_Age End Property Public Property Let Height(value) m_Height = value End Property Public Property Get Height() Height = m_Height End Property End Class Class NameValidation Private m_Name Public Function Init(name) m_Name = name End Function Public Function Validate() Dim validationObject If Len(m_Name) < 5 Then Set validationObject = New ValidationError Else Set validationObject = New ValidationSuccess End If validationObject.CellValue = m_Name Set Validate = validationObject End Function End Class Class AgeValidation Private m_Age Public Function Init(age) m_Age = age End Function Public Function Validate() Dim validationObject If m_Age < 18 Then Set validationObject = New ValidationError ElseIf m_Age = 18 Then Set validationObject = New ValidationWarning Else Set validationObject = New ValidationSuccess End If validationObject.CellValue = m_Age Set Validate = validationObject End Function End Class Class HeightValidation Private m_Height Public Function Init(height) m_Height = height End Function Public Function Validate() Dim validationObject If m_Height > 400 Then Set validationObject = New ValidationError ElseIf m_Height = 324 Then Set validationObject = New ValidationWarning Else Set validationObject = New ValidationSuccess End If validationObject.CellValue = m_Height Set Validate = validationObject End Function End Class Class ValidationError Private m_CSSClass Private m_CellValue Public Property Get CSSClass() CSSClass = "error" End Property Public Property Let CellValue(value) m_CellValue = value End Property Public Property Get CellValue() CellValue = m_CellValue End Property End Class Class ValidationWarning Private m_CSSClass Private m_CellValue Public Property Get CSSClass() CSSClass = "warning" End Property Public Property Let CellValue(value) m_CellValue = value End Property Public Property Get CellValue() CellValue = m_CellValue End Property End Class Class ValidationSuccess Private m_CSSClass Private m_CellValue Public Property Get CSSClass() CSSClass = "" End Property Public Property Let CellValue(value) m_CellValue = value End Property Public Property Get CellValue() CellValue = m_CellValue End Property End Class Class ModelValidator Public Function ValidateModel(model) Dim modelValidation : Set modelValidation = New CollectionClass ' Validate name Dim name : Set name = New NameValidation name.Init model.Name modelValidation.Add name ' Validate age Dim age : Set age = New AgeValidation age.Init model.Age modelValidation.Add age ' Validate height Dim height : Set height = New HeightValidation height.Init model.Height modelValidation.Add height Dim validatedProperties : Set validatedProperties = New CollectionClass Dim modelVal For Each modelVal In modelValidation.Items() validatedProperties.Add modelVal.Validate() Next Set ValidateModel = validatedProperties End Function End Class Dim modelCollection : Set modelCollection = New CollectionClass Dim user1 : Set user1 = New UserModel user1.Name = "Mike" user1.Age = 12 user1.Height = 32 modelCollection.Add user1 Dim user2 : Set user2 = New UserModel user2.Name = "Phil" user2.Age = 18 user2.Height = 432 modelCollection.Add user2 Dim user3 : Set user3 = New UserModel user3.Name = "Michele" user3.Age = 32 user3.Height = 324 modelCollection.Add user3 ' Validate all models in the collection Dim modelValue Dim validatedModels : Set validatedModels = New CollectionClass For Each modelValue In modelCollection.Items() Dim objModelValidator : Set objModelValidator = New ModelValidator validatedModels.Add objModelValidator.ValidateModel(modelValue) Next %> <table> <tr> <td>Name</td> <td>Age</td> <td>Height</td> </tr> <% Dim r, c For Each r In validatedModels.Items() %><tr><% For Each c In r.Items() %><td class="<%= c.CSSClass %>"><%= c.CellValue %></td><% Next %></tr><% Next %> </table> Thank you.

  • Segfault on copy constructor for string

    - by user2756569
    I'm getting a segfault on a line where I'm creating a c++ string with the copy constructor. I've looked at some of the similar issues, but they're all due to passing in a bad c++ string object. I'm just passing in a raw string, so I'm not sure what my issue is. I'll paste the relevant snippets of code (it's taken from several different files, so it might look a bit jumbled). The segfault occurs in the 4th line of the default constructor for the Species class. Species::Species(string _type) { program_length = 0; cout << _type << " 1\n"; cout << type << " 2\n"; type = string(_type); } Grid::Grid(int _width, int _height) { *wall = Species("wall"); *empty = Species("empty"); turn_number = 0; width = _width; height = _height; for(int a= 0; a < 100; a++) for(int b = 0; b< 100; b++) { Creature empty_creature = Creature(*empty,a,b,NORTH,this); (Grid::map)[a][b] = empty_creature; } } int main() { Grid world = Grid(8,8); } class Grid { protected: Creature map[100][100]; int width,height; int turn_number; Species *empty; Species *wall; public: Grid(); Grid(int _width, int _height); void addCreature(Species &_species, int x, int y, Direction orientation); void addWall(int x, int y); void takeTurn(); void infect(int x, int y, Direction orientation, Species &_species); void hop(int x, int y, Direction orientation); bool ifWall(int x, int y, Direction orientation); bool ifEnemy(int x, int y, Direction orientation, Species &_species); bool ifEmpty(int x, int y, Direction orientation); void print(); }; class Species { protected: int program_length; string program[100]; string type; public: species(string _type); void addInstruction(string instruction); bool isWall(); bool isEmpty(); bool isEnemy(Species _enemy); string instructionAt(int index); string getType(); };

  • iPhone multi-touch scale and rotate, how to prevent scale?

    - by russhill
    I have existing code for tracking multi-touch positions and then rotating and scaling the item - in this case an image - appropriately. The code works really well and in itself is perfect, however for this particular task, I need the rotation ONLY. I have spent time trying to work out what is going on in this routine, but maths is not my strong point so wanted to see if anyone could assist? - (CGAffineTransform)incrementalTransformWithTouches:(NSSet *)touches { NSArray *sortedTouches = [[touches allObjects] sortedArrayUsingSelector:@selector(compareAddress:)]; NSInteger numTouches = [sortedTouches count]; // No touches if (numTouches == 0) { return CGAffineTransformIdentity; } // Single touch if (numTouches == 1) { UITouch *touch = [sortedTouches objectAtIndex:0]; CGPoint beginPoint = *(CGPoint *)CFDictionaryGetValue(touchBeginPoints, touch); CGPoint currentPoint = [touch locationInView:self.superview]; return CGAffineTransformMakeTranslation(currentPoint.x - beginPoint.x, currentPoint.y - beginPoint.y); } // If two or more touches, go with the first two (sorted by address) UITouch *touch1 = [sortedTouches objectAtIndex:0]; UITouch *touch2 = [sortedTouches objectAtIndex:1]; CGPoint beginPoint1 = *(CGPoint *)CFDictionaryGetValue(touchBeginPoints, touch1); CGPoint currentPoint1 = [touch1 locationInView:self.superview]; CGPoint beginPoint2 = *(CGPoint *)CFDictionaryGetValue(touchBeginPoints, touch2); CGPoint currentPoint2 = [touch2 locationInView:self.superview]; double layerX = self.center.x; double layerY = self.center.y; double x1 = beginPoint1.x - layerX; double y1 = beginPoint1.y - layerY; double x2 = beginPoint2.x - layerX; double y2 = beginPoint2.y - layerY; double x3 = currentPoint1.x - layerX; double y3 = currentPoint1.y - layerY; double x4 = currentPoint2.x - layerX; double y4 = currentPoint2.y - layerY; // Solve the system: // [a b t1, -b a t2, 0 0 1] * [x1, y1, 1] = [x3, y3, 1] // [a b t1, -b a t2, 0 0 1] * [x2, y2, 1] = [x4, y4, 1] double D = (y1-y2)*(y1-y2) + (x1-x2)*(x1-x2); if (D < 0.1) { return CGAffineTransformMakeTranslation(x3-x1, y3-y1); } double a = (y1-y2)*(y3-y4) + (x1-x2)*(x3-x4); double b = (y1-y2)*(x3-x4) - (x1-x2)*(y3-y4); double tx = (y1*x2 - x1*y2)*(y4-y3) - (x1*x2 + y1*y2)*(x3+x4) + x3*(y2*y2 + x2*x2) + x4*(y1*y1 + x1*x1); double ty = (x1*x2 + y1*y2)*(-y4-y3) + (y1*x2 - x1*y2)*(x3-x4) + y3*(y2*y2 + x2*x2) + y4*(y1*y1 + x1*x1); return CGAffineTransformMake(a/D, -b/D, b/D, a/D, tx/D, ty/D); } I have tried to read up on the way matrix's work, but cannot figure it out entirely. More likely to be the issue is the calculations, which as I mention is not my strong point. What I need from this routine is a transform that performs my rotation but ignores scale - so the distance between the 2 finger touch points is ignored and scale is not affected. I have looked at other routines on the internet to handle multi-touch rotation but all the ones I tried had issues in some way or other, whereas the above code is spot on for scale and rotate actions. Any help appreciated!

  • can't implement jquery jScrollPane to replace browser's scrollbars

    - by Zack
    I am trying to replace browser's scrollbars with jScrollPane (jQuery), it won't work. Here are two attempts to implement it: a basic attempt, and an attempt to imitate the full page demo for jScrollPane. I've been trying everything I could think of to figure out what didn't work, but couldn't. here is my code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title></title> <!-- styles needed by jScrollPane --> <link type="text/css" href="style/jquery.jscrollpane.css" rel="stylesheet" media="all" /> <style type="text/css" id="page-css"> /* Styles specific to this particular page */ html { overflow: auto; } #full-page-container { overflow: auto; } .scroll-pane { width: 100%; height: 200px; overflow: auto; } .horizontal-only { height: auto; max-height: 200px; } </style> <!-- latest jQuery direct from google's CDN --> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script> <!-- the mousewheel plugin --> <script type="text/javascript" src="script/jquery.mousewheel.js"></script> <!-- the jScrollPane script --> <script type="text/javascript" src="script/jquery.jscrollpane.min.js"></script> <script type="text/javascript" id="sourcecode"> $(function () { var win = $(window); // Full body scroll var isResizing = false; win.bind( 'resize', function () { if (!isResizing) { isResizing = true; var container = $('#full-page-container'); // Temporarily make the container tiny so it doesn't influence the // calculation of the size of the document container.css( { 'width': 1, 'height': 1 } ); // Now make it the size of the window... container.css( { 'width': win.width(), 'height': win.height() } ); isResizing = false; container.jScrollPane( { 'showArrows': true } ); } } ).trigger('resize'); // Workaround for known Opera issue which breaks demo (see // http://jscrollpane.kelvinluck.com/known_issues.html#opera-scrollbar ) $('body').css('overflow', 'hidden'); // IE calculates the width incorrectly first time round (it // doesn't count the space used by the native scrollbar) so // we re-trigger if necessary. if ($('#full-page-container').width() != win.width()) { win.trigger('resize'); } }); </script> </head> <body> <div id="full-page-container"> This is the most basic implementation of jScrollPane I could create, if I am not wrong this has all it should take, yet it doesn't work. a little lorem ipsum to make the scrollbars show up: [here come's lot's of lorem ipsum text in the actual page...] </div> </body> </html> The other option is the same, with a link to demo.css and demo.js.

  • multple inner joins 3 or more crashes mysql server 5.1.30 opensolaris

    - by user331849
    when doing simple query on 4 inner joined tables, the server crashes with the output below appearing in the the mysql .err file. eg. select * from table1 inner join table2 on table1.a = table2.a and table1.b = table2.b inner join table3 on table2.a = table3.a and table2.c = table3.c inner join table4 on table3.a = table4.a and table3.d = table4.d If i remove one of the tables it executes fine.

  • Text misaligns in IE

    - by kingrichard2005
    I have a ASP.net web page I'm working with, I didn't create it myself, with the following HTML code: <DIV style="POSITION: absolute; TEXT-ALIGN: center; WIDTH: 1400px; TOP: 60px; LEFT: 125px"> <SPAN style="TEXT-ALIGN: center; FONT-SIZE: xx-large" id=labelInstructions>Some Text: <BR><BR></SPAN> <TABLE style="WIDTH: 1200px" border=1 align=center> <TBODY> <TR> <TD><LABEL style="FONT-SIZE: x-large" for=FileUpload1>ENTER Path: </LABEL><INPUT id=FileUpload1 size=70 type=file name=FileUpload1></TD> </TR> <TR> <TD><SPAN style="COLOR: red; FONT-SIZE: medium" id=fileUploadError><BR><BR></SPAN></TD> </TR> <TR> <TD> <TABLE style="WIDTH: 1200px" border=1> <TBODY> <TR> <TD style="WIDTH: 400px; FONT-SIZE: x-large" vAlign=top align=right>FILE CONTENT INSTRUCTIONS:</TD> <TD style="WIDTH: 850px; FONT-SIZE: x-large" vAlign=top align=left>INSTRUCTION 1<BR>INSTRUCTION 2<BR></TD></TR> <TR><TD></TD></TR> <TR> <TD style="WIDTH: 400px; FONT-SIZE: x-large" vAlign=top align=right>FILE CONTENT EXAMPLE:</TD> <TD style="WIDTH: 850px; FONT-SIZE: x-large" vAlign=top align=left>EXAMPLE 1<BR>EXAMPLE 2<BR><BR></TD> </TR> </TBODY> </TABLE> </TD> </TR> </TBODY> </TABLE> </DIV> When this html is displayed in IE, I notice that the alignment of the text in the cells in the inner table, i.e. the table that is in the third cell of the outer table, is distorted when zooming in and out on it. I have a fixed table setting in pixels instead of percentages, so I don't understand why this is an issue. I want the text in the cells to stay in the same position when zooming. The code must be manipulated from the code behind, so I cannot create a separate CSS file. Any help is appreciated. Here are two examples to illustrate what I'm talking about: Normal zoom at 100%: Zoom at 75%: Notice in the second image the two table cells at the bottom are slightly offset to the left. UPDATE: Yes, I understand, we will be implementing a new system in the near future. Obviously this is old and very non-standard, this was dropped in my lap when I started working with it. And we're coming up with plans for a new system to replace it, in the meantime, this is what I have to deal with.

  • Create / build / generate a web form that can be on my server and has modern looks and could be impl

    - by Luay
    I have a small web site and would like to add a 'contact us' form and a 'feedback' form. i would like the forms to satisfy the following: 1- be modern looking (with beautiful css effects) 2- the form fields are validated properly and 'inline'. What I mean is once a user skips a required field or enters an email address incorrectly some kind of tooltip or icon is displayed to ask him to cerrect the error (as opposed to a message box that appears after the user clicks 'submit') 3- once the submit button is clicked the form contents are emailed to me. 4- the whole thing can be setup by a noob like myself. 5- no ads on the form I have been searching for at least 5 days for a solution but I can't seem to find anything the would satisfy the above 5 conditions. I don't mind paying for a solution as long as it is hosted on my site and it is a one off payment and not a monthly payment. So far my search has lead me to the following: 1 wufoo. The good: the generated forms seem to look okay but not the best there is. The bad: the free service is limited to 100 submissions. ads on the form. it is not hosted on my server. Paid service requires monthly payments 2- emailmeform: almost same as above except the generated form looks old. They do have an offer where you pay only $4 to get the form and set it up on your own site but that doesn't solve the fact that the forms look old. 3- formAssembly: same as above with minor variations (the generated form looks better) 4- formchamp, formthis, kontaktr,... And other similar online services: the same problem. either the form generated looks outdated or require monthly payments or they put ads...they don't satisfy my conditions. 5- coffeecup form builder. a desktop software. The problem is the generated forms look too old and use flash. 6- simfatic. Another software. Much better than coffeecup. almost satisfies my conditions but the forms not as good as I like. 7- many, many php scripts or html templates that look so outdated or fail when tested (probably because they are too old). Seriously guys, how hard is this. At least 90%+ of website contain at least a 'contact us' form. Why aren't there better solutions? if there is I can't seem to find them. In terms of looks I want something similar to this: http://web-kreation.com/articles/lightform-free-ajaxphp-contact-form/ It is called lightform. And this is a perfect example of what I mean by 'inline' validation. the only problem: there is no script to handle sending the mail. Even if I find one, I don't know how to modify it for my needs. So could you please help me out. I really can't search anymore. I reached rock bottom with this issue. I need a complete solution. If nothing exists then at least a: 1- form template (html) that looks nice and can easily be modified 2- a validation script that does 'inline' validation like the example above (or similar to it) and can be easily implemented by a noob like me to work with the html form. 3- a php script that will handle sending the email and can be easily implemented (all three working in harmony). I hope there is a complete solution but am I asking for too much? Pretty please...help...

  • PHP script causes segmentation fault then the browser asks me to download the .php file with nothing in it?

    - by John
    I've noticed an unusual problem with some of my php programs. Sometimes when visiting a page like profile.edit.php, the browser throws a dialogue box asking to download profile.edit.php page. When I download it, there's nothing in the file. profile.edit.php is supposed to be a web form that edits user information. I've noticed this on some of my other php pages as well. I look in my apache error logs, and I see a segmentation fault message: [Mon Mar 08 15:40:10 2010] [notice] child pid 480 exit signal Segmentation fault (11) And also, the issue may or may not appear depending on which server I deploy my application too. Additonal Details This doesn't happen all the time though. It only happens sometimes. For example, profile.edit.php will load properly. But as soon as I hit the save button (form action="profile.edit.php?save=true"), then the page asks me to download profile.edit.php. Could it be that sometimes my php scripts consume too much resources? Sample code Upon save action, my profile.edit.php includes a data_access_object.php file. I traced the code in data_access_object.php to this line here if($params[$this->primaryKey]) { $q = "UPDATE $this->tableName SET ".implode(', ', $fields)." WHERE ".$this->primaryKey." = ?$this->primaryKey"; $this->bind($this->primaryKey, $params[$this->primaryKey], $this->tblFields[$this->primaryKey]['mysqlitype']); } else { $q = "INSERT $this->tableName SET ".implode(', ', $fields); } // Code executes perfectly up to this point // echo 'print this'; exit; // if i uncomment this line, profile.edit.php will actually show 'print this'. If I leave it commented, the browser will ask me to download profile.edit.php if(!$this->execute($q)){ $this->errorSave = -3; return false;} // When I jumped into the function execute(), every line executed as expected, right up to the return statement. And if it helps, here's the function execute($sql) in data_access_object.php function execute($sql) { // find all list types and explode them // eg. turn ?listId into ?listId0,?listId1,?listId2 $arrListParam = array_bubble_up('arrayName', $this->arrBind); foreach($arrListParam as $listName) if($listName) { $explodeParam = array(); $arrList = $this->arrBind[$listName]['value']; foreach($arrList as $key=>$val) { $newParamName = $listName.$key; $this->bind($newParamName,$val,$this->arrBind[$listName]['type']); $explodeParam[] = '?'.$newParamName; } $sql = str_replace("?$listName", implode(',',$explodeParam), $sql); } // replace all ?varName with ? for syntax compliance $sqlParsed = preg_replace('/\?[\w\d_\.]+/', '?', $sql); $this->stmt->prepare($sqlParsed); // grab all the parameters from the sql to create bind conditions preg_match_all('/\?[\w\d_\.]+/', $sql, $matches); $matches = $matches[0]; // store bind conditions $types = ''; $params = array(); foreach($matches as $paramName) { $types .= $this->arrBind[str_replace('?', '', $paramName)]['type']; $params[] = $this->arrBind[str_replace('?', '', $paramName)]['value']; } $input = array('types'=>$types) + $params; // bind it if(!empty($types)) call_user_func_array(array($this->stmt, 'bind_param'), $input); $stat = $this->stmt->execute(); if($GLOBALS['DEBUG_SQL']) echo '<p style="font-weight:bold;">SQL error after execution:</p> ' . $this->stmt->error.'<p>&nbsp;</p>'; $this->arrBind = array(); return $stat; }

  • What does a WinForm application need to be designed for usability, and be robust, clean, and profess

    - by msorens
    One of the principal problems impeding productivity in software implementation is the classic conundrum of “reinventing the wheel”. Of late I am a .NET developer and even the wonderful wizardry of .NET and Visual Studio covers only a portion of this challenging issue. Below I present my initial thoughts both on what is available and what should be available from .NET on a WinForm, focusing on good usability. That is, aspects of an application exposed to the user and making the user experience easier and/or better. (I do include a couple items not visible to the user because I feel strongly about them, such as diagnostics.) I invite you to contribute to these lists. LIST A: Components provided by .NET These are substantially complete components provided by .NET, i.e. those requiring at most trivial coding to use. “About” dialog -- add it with a couple clicks then customize. Persist settings across invocations -- .NET has the support; just use a few lines of code to glue them together. Migrate settings with a new version -- a powerful one, available with one line of code. Tooltips (and infotips) -- .NET includes just plain text tooltips; third-party libraries provide richer ones. Diagnostic support -- TraceSources, TraceListeners, and more are built-in. Internationalization -- support for tailoring your app to languages other than your own. LIST B: Components not provided by .NET These are not supplied at all by .NET or supplied only as rudimentary elements requiring substantial work to be realized. Splash screen -- a small window present during program startup with your logo, loading messages, etc. Tip of the day -- a mini-tutorial presented one bit at a time each time the user starts your app. Check for available updates -- facility to query a server to see if the user is running the latest version of your app, then provide a simple way to upgrade if a new version is found. Maximize to multiple monitors -- the canonical window allows you to maximize to a single monitor only; in my apps I allow maximizing across multiple monitors with a click. Taskbar notifier -- flash the taskbar when your backgrounded app has new info for the user. Options dialogs -- multi-page dialogs letting the user customize the app settings to his/her own preferences. Progress indicator -- for long running operations give the user feedback on how far there is left to go. Memory gauge -- an indicator (either absolute or percentage) of how much memory is used by your app. LIST C: Stylistic and/or tiny bits of functionality This list includes bits of functionality that are too tiny to merit being called a component, along with stylistic concerns (that admittedly do overlap with the Windows User Experience Interaction Guidelines). Design a form for resizing -- unless you are restricting your form to be a fixed size, use anchors and docking so that it does what is reasonable when enlarged or shrunk by the user. Set tab order on a form -- repeated tab presses by the user should advance from field to field in a logical order rather than the default order in which you added fields. Adjust controls to be aware of operating modes -- When starting a background operation with, for example, a “Go” button, disable that “Go” button until the operation completes. Provide access keys for all menu items (per UXGuide). Provide shortcut keys for commonly used menu items (per UXGuide). Set up some (global or important or common) shortcut keys without associating to menu items. Allow some menu items to be invoked with or without modifier keys (shift, control, alt) where the modifier key is useful to vary the operation slightly. Hook up Escape and Enter on child forms to do what is reasonable. Decorate any library classes with documentation-comments and attributes -- this allows Visual Studio to leverage them for Intellisense and property descriptions. Spell check your code! What else would you include?

  • Node.js, Cygwin and Socket.io walk into a bar... Node.js throws ENOBUFS and everyone dies...

    - by A Wizard Did It
    I'm hoping someone here can help me out, I'm not having much luck figuring this out myself. I'm running node.js version 0.3.1 on Cygwin. I'm using Connect and Socket.io. I seem to be having some random problems with DNS or something, I haven't quite figured it out. The end result is that I the server is running fine, but when a browser attempts to connect to it the initial HTTP Request works, Socket.io connects, and then the server dies (output below). I don't think it has anything to do with the HTTP request because the server gets a lot data posted to it, and it was receiving requests and responding up until my connection that killed it. I've googled around and the closest thing I've found is DNS being set improperly. It's a network program meant to run only on an internal network, so I've set the nameserver x.x.x.x in my /etc/resolv.conf to the internal DNS. I've also added nameserver 8.8.8.8 in addition. I'm not sure what else to check, but would be grateful of any help.

I've edited the source to include && errno != ENOBUFS which now prevents the server from dying, however now the LDAP request isn't working. I'm not sure what the problem is that would cause that though. As I mentioned this is an internal only application, so I set the DNS servers in /etc/resolv.conf to the DNS servers that are being applied to the host machine. Not sure if this is part of the issue? EDIT 2 Here's some output from gdb --args ./node_g --debug ../myscript.js.

  • iPhone App Crashes when merging managed object contexts

    - by DVG
    Short Version: Using two managed object contexts, and while the context is saving to the store the application bombs when I attempt to merge the two contexts and reload the table view. Long Version: Okay, so my application is set up as thus. 3 view controllers, all table views. Platforms View Controller - Games View Controller (Predicated upon platform selection) - Add Game View Controller I ran into a problem when Games View Controller was bombing when adding a new entry to the context, because the fetched results contorller wanted to update the view for something that didn't match the predicate. As a solution, I rebuilt the Add Controller to use a second NSManagedObject Context, called adding context, following the design pattern in the Core Data Books example. My Games List View Controller is a delegate for the add controller, to handle all the saving, so my addButtonPressed method looks like this - (IBAction) addButtonPressed: (id) sender { AddGameTableViewController *addGameVC = [[AddGameTableViewController alloc] initWithNibName:@"AddGameTableViewController" bundle:nil]; NSManagedObjectContext *aAddingContext = [[NSManagedObjectContext alloc] init]; self.addingContext = aAddingContext; [aAddingContext release]; [addingContext setPersistentStoreCoordinator:[[gameResultsController managedObjectContext] persistentStoreCoordinator]]; addGameVC.context = addingContext; addGameVC.delegate = self; addGameVC.newGame = (Game *)[NSEntityDescription insertNewObjectForEntityForName:@"Game" inManagedObjectContext:addingContext]; UINavigationController *addNavCon = [[UINavigationController alloc] initWithRootViewController:addGameVC]; [self presentModalViewController:addNavCon animated:YES]; [addGameVC release]; [addNavCon release]; } There is also a delegate method which handles the saving. This all works swimmingly. The issue is getting the table view controller in the GameListViewController to update itself. Per the example, an observer is added to watch for the second context to be saved, and then to merge the addingContext with the primary one. So I have: - (void)addViewController:(AddGameTableViewController *)controller didFinishWithSave:(BOOL)save { if (save) { NSNotificationCenter *dnc = [NSNotificationCenter defaultCenter]; [dnc addObserver:self selector:@selector(addControllerContextDidSave:) name:NSManagedObjectContextDidSaveNotification object:addingContext]; //snip! Context Save Code [dnc removeObserver:self name:NSManagedObjectContextDidSaveNotification object:addingContext]; } self.addingContext = nil; [self dismissModalViewControllerAnimated:YES]; } - (void)addControllerContextDidSave:(NSNotification*)saveNotification { NSManagedObjectContext *myContext = [gameResultsController managedObjectContext]; [myContext mergeChangesFromContextDidSaveNotification:saveNotification]; } So now, what happens is after save is pressed, the application hangs for a moment and then crashes. The save is processed, as the new game is present when I relaunch the application, and the application seems to be flowing as appropriate, but it bombs out for reasons that are beyond my understanding. NSLog of the saveNotification spits out this: NSConcreteNotification 0x3b557f0 {name = NSManagingContextDidSaveChangesNotification; object = <NSManagedObjectContext: 0x3b4bb90>; userInfo = { inserted = {( <Game: 0x3b4f510> (entity: Game; id: 0x3b614e0 <x-coredata://13168366-B8E7-41C8-B384-BAF14A5E08D9/Game/p2> ; data: { name = "Final Fantasy XIII"; platform = 0x3b66910 <x-coredata://13168366-B8E7-41C8-B384-BAF14A5E08D9/Platform/p20>; }) )}; updated = {( <Platform: 0x3b67650> (entity: Platform; id: 0x3b66910 <x-coredata://13168366-B8E7-41C8-B384-BAF14A5E08D9/Platform/p20> ; data: { games = ( 0x3b614e0 <x-coredata://13168366-B8E7-41C8-B384-BAF14A5E08D9/Game/p2>, 0x603a530 <x-coredata://13168366-B8E7-41C8-B384-BAF14A5E08D9/Game/p1> ); name = "Xbox 360"; }) )}; }} I've tried both a simple [self.tableView reloadData]; and the more complicated multi-method table updating structure in the Core Data Books example. Both produce the same result.

  • Strange performance behaviour for 64 bit modulo operation

    - by codymanix
    The last three of these method calls take approx. double the time than the first four. The only difference is that their arguments doesn't fit in integer anymore. But should this matter? The parameter is declared to be long, so it should use long for calculation anyway. Does the modulo operation use another algorithm for numbersmaxint? I am using amd athlon64 3200+, winxp sp3 and vs2008. Stopwatch sw = new Stopwatch(); TestLong(sw, int.MaxValue - 3l); TestLong(sw, int.MaxValue - 2l); TestLong(sw, int.MaxValue - 1l); TestLong(sw, int.MaxValue); TestLong(sw, int.MaxValue + 1l); TestLong(sw, int.MaxValue + 2l); TestLong(sw, int.MaxValue + 3l); Console.ReadLine(); static void TestLong(Stopwatch sw, long num) { long n = 0; sw.Reset(); sw.Start(); for (long i = 3; i < 20000000; i++) { n += num % i; } sw.Stop(); Console.WriteLine(sw.Elapsed); } EDIT: I now tried the same with C and the issue does not occur here, all modulo operations take the same time, in release and in debug mode with and without optimizations turned on: #include "stdafx.h" #include "time.h" #include "limits.h" static void TestLong(long long num) { long long n = 0; clock_t t = clock(); for (long long i = 3; i < 20000000LL*100; i++) { n += num % i; } printf("%d - %lld\n", clock()-t, n); } int main() { printf("%i %i %i %i\n\n", sizeof (int), sizeof(long), sizeof(long long), sizeof(void*)); TestLong(3); TestLong(10); TestLong(131); TestLong(INT_MAX - 1L); TestLong(UINT_MAX +1LL); TestLong(INT_MAX + 1LL); TestLong(LLONG_MAX-1LL); getchar(); return 0; } EDIT2: Thanks for the great suggestions. I found that both .net and c (in debug as well as in release mode) does't not use atomically cpu instructions to calculate the remainder but they call a function that does. In the c program I could get the name of it which is "_allrem". It also displayed full source comments for this file so I found the information that this algorithm special cases the 32bit divisors instead of dividends which was the case in the .net application. I also found out that the performance of the c program really is only affected by the value of the divisor but not the dividend. Another test showed that the performance of the remainder function in the .net program depends on both the dividend and divisor. BTW: Even simple additions of long long values are calculated by a consecutive add and adc instructions. So even if my processor calls itself 64bit, it really isn't :( EDIT3: I now ran the c app on a windows 7 x64 edition, compiled with visual studio 2010. The funny thing is, the performance behavior stays the same, although now (I checked the assembly source) true 64 bit instructions are used.

  • Element.appendChild() hosed in IE .. workaround? (related to innerText vs textContent)

    - by Rowe Morehouse
    I've heard that using el.innerText||el.textContent can yield unreliable cross-browswer results, so I'm walking the DOM tree to collect text nodes recursively, and write them into tags in the HTML body. What this script does is read hash substring valus from the window.location and write them into the HTML. This script is working for me in Chrome & Firefox, but choking in IE. I call the page with an URL syntax like this: http://example.com/pagename.html#dyntext=FOO&dynterm=BAR&dynimage=FRED UPDATE UPDATE UPDATE Solution: I moved the scripts to before </body> (where they should have been) then removed console.log(sPageURL); and now it's working in Chrome, Firefox, IE8 and IE9. This my workaround for the innerText vs textContent crossbrowser issue when you are just placing text rather than getting text. In this case, getting hash substring values from the window.location and writing them into the page. <html> <body> <span id="dyntext-span" style="font-weight: bold;"></span><br /> <span id="dynterm-span" style="font-style: italic;"></span><br /> <span id="dynimage-span" style="text-decoration: underline;"></span><br /> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js"></script> <script> $(document).ready(function() { var tags = ["dyntext", "dynterm", "dynimage"]; for (var i = 0; i < tags.length; ++i) { var param = GetURLParameter(tags[i]); if (param) { var dyntext = GetURLParameter('dyntext'); var dynterm = GetURLParameter('dynterm'); var dynimage = GetURLParameter('dynimage'); } } var elem = document.getElementById("dyntext-span"); var text = document.createTextNode(dyntext); elem.appendChild(text); var elem = document.getElementById("dynterm-span"); var text = document.createTextNode(dynterm); elem.appendChild(text); var elem = document.getElementById("dynimage-span"); var text = document.createTextNode(dynimage); elem.appendChild(text); }); function GetURLParameter(sParam) { var sPageURL = window.location.hash.substring(1); var sURLVariables = sPageURL.split('&'); for (var i = 0; i < sURLVariables.length; i++) { var sParameterName = sURLVariables[i].split('='); if (sParameterName[0] == sParam) { return sParameterName[1]; } } } </script> </body> </html> FINAL UPDATE If your hash substring values require spaces (like a linguistic phrase with three words, for example) then separate the words with the + character in your URI, and replace the unicode \u002B character with a space when you create each text node, like this: var elem = document.getElementById("dyntext-span"); var text = document.createTextNode(dyntext.replace(/\u002B/g, " ")); elem.appendChild(text); var elem = document.getElementById("dynterm-span"); var text = document.createTextNode(dynterm.replace(/\u002B/g, " ")); elem.appendChild(text); var elem = document.getElementById("dynimage-span"); var text = document.createTextNode(dynimage.replace(/\u002B/g, " ")); elem.appendChild(text); Now form your URI like this: http://example.com/pagename.html#dyntext=FOO+MAN+CHU&dynterm=BAR+HOPPING&dynimage=FRED+IS+DEAD

  • Magento - Data is not inserted into database, but the id is autoincremented

    - by Joseph
    I am working on a new payment module for Magento and have come across an issue that I cannot explain. The following code that runs after the credit card is verified: $table_prefix = Mage::getConfig()->getTablePrefix(); $tableName = $table_prefix.'authorizecim_magento_id_link'; $resource = Mage::getSingleton('core/resource'); $writeconnection = $resource->getConnection('core_write'); $acPI = $this->_an_customerProfileId; $acAI = $this->_an_customerAddressId; $acPPI = $this->_an_customerPaymentProfileId; $sql = "insert into {$tableName} values ('', '$customerId', '$acPI', '$acPI', '3')"; $writeconnection->query($sql); $sql = "insert into {$tableName} (magCID, anCID, anOID, anObjectType) values ('$customerId', '$acPI', '$acAI', '2')"; $writeconnection->query($sql); $sql = "insert into {$tableName} (magCID, anCID, anOID, anObjectType) values ('$customerId', '$acPI', '$acPPI', '1')"; $writeconnection->query($sql); I have verified using Firebug and FirePHP that the SQL queries are syntactically correct and no errors are returned. The odd thing here is that I have checked the database, and the autoincrement value is incremented on every run of the code. However, no rows are inserted in the database. I have verified this by adding a die(); statement directly after the first write. Any ideas why this would be occuring? The relative portion of the config.xml is this: <config> <global> <models> <authorizecim> <class>CPAP_AuthorizeCim_Model</class> </authorizecim> <authorizecim_mysql4> <class>CPAP_AuthorizeCim_Model_Mysql4</class> <entities> <anlink> <table>authorizecim_magento_id_link</table> </anlink> </entities> <entities> <antypes> <table>authorizecim_magento_types</table> </antypes> </entities> </authorizecim_mysql4> </models> <resources> <authorizecim_setup> <setup> <module>CPAP_AuthorizeCim</module> <class>CPAP_AuthorizeCim_Model_Resource_Mysql4_Setup</class> </setup> <connection> <use>core_setup</use> </connection> </authorizecim_setup> <authorizecim_write> <connection> <use>core_write</use> </connection> </authorizecim_write> <authorizecim_read> <connection> <use>core_read</use> </connection> </authorizecim_read> </resources> </global> </config>

  • How to reduce virtual memory by optimising my PHP code?

    - by iCeR
    My current code (see below) uses 147MB of virtual memory! My provider has allocated 100MB by default and the process is killed once run, causing an internal error. The code is utilising curl multi and must be able to loop with more than 150 iterations whilst still minimizing the virtual memory. The code below is only set at 150 iterations and still causes the internal server error. At 90 iterations the issue does not occur. How can I adjust my code to lower the resource use / virtual memory? Thanks! <?php function udate($format, $utimestamp = null) { if ($utimestamp === null) $utimestamp = microtime(true); $timestamp = floor($utimestamp); $milliseconds = round(($utimestamp - $timestamp) * 1000); return date(preg_replace('`(?<!\\\\)u`', $milliseconds, $format), $timestamp); } $url = 'https://www.testdomain.com/'; $curl_arr = array(); $master = curl_multi_init(); for($i=0; $i<150; $i++) { $curl_arr[$i] = curl_init(); curl_setopt($curl_arr[$i], CURLOPT_URL, $url); curl_setopt($curl_arr[$i], CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl_arr[$i], CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($curl_arr[$i], CURLOPT_SSL_VERIFYPEER, FALSE); curl_multi_add_handle($master, $curl_arr[$i]); } do { curl_multi_exec($master,$running); } while($running > 0); for($i=0; $i<150; $i++) { $results = curl_multi_getcontent ($curl_arr[$i]); $results = explode("<br>", $results); echo $results[0]; echo "<br>"; echo $results[1]; echo "<br>"; echo udate('H:i:s:u'); echo "<br><br>"; usleep(100000); } ?> Processor Information Total processors: 8 Processor #1 Vendor GenuineIntel Name Intel(R) Xeon(R) CPU E5405 @ 2.00GHz Speed 1995.120 MHz Cache 6144 KB Processor #2 Vendor GenuineIntel Name Intel(R) Xeon(R) CPU E5405 @ 2.00GHz Speed 1995.120 MHz Cache 6144 KB Processor #3 Vendor GenuineIntel Name Intel(R) Xeon(R) CPU E5405 @ 2.00GHz Speed 1995.120 MHz Cache 6144 KB Processor #4 Vendor GenuineIntel Name Intel(R) Xeon(R) CPU E5405 @ 2.00GHz Speed 1995.120 MHz Cache 6144 KB Processor #5 Vendor GenuineIntel Name Intel(R) Xeon(R) CPU E5405 @ 2.00GHz Speed 1995.120 MHz Cache 6144 KB Processor #6 Vendor GenuineIntel Name Intel(R) Xeon(R) CPU E5405 @ 2.00GHz Speed 1995.120 MHz Cache 6144 KB Processor #7 Vendor GenuineIntel Name Intel(R) Xeon(R) CPU E5405 @ 2.00GHz Speed 1995.120 MHz Cache 6144 KB Processor #8 Vendor GenuineIntel Name Intel(R) Xeon(R) CPU E5405 @ 2.00GHz Speed 1995.120 MHz Cache 6144 KB Memory Information Memory for crash kernel (0x0 to 0x0) notwithin permissible range Memory: 8302344k/9175040k available (2176k kernel code, 80272k reserved, 901k data, 228k init, 7466304k highmem) System Information Linux server3.server.com 2.6.18-194.17.1.el5PAE #1 SMP Wed Sep 29 13:31:51 EDT 2010 i686 i686 i386 GNU/Linux Physical Disks SCSI device sda: 1952448512 512-byte hdwr sectors (999654 MB) sda: Write Protect is off sda: Mode Sense: 03 00 00 08 SCSI device sda: drive cache: write back SCSI device sda: 1952448512 512-byte hdwr sectors (999654 MB) sda: Write Protect is off sda: Mode Sense: 03 00 00 08 SCSI device sda: drive cache: write back sd 0:1:0:0: Attached scsi disk sda sd 4:0:0:0: Attached scsi removable disk sdb sd 0:1:0:0: Attached scsi generic sg4 type 0 sd 4:0:0:0: Attached scsi generic sg7 type 0 Current Memory Usage total used free shared buffers cached Mem: 8306672 7847384 459288 0 487912 6444548 -/+ buffers/cache: 914924 7391748 Swap: 4095992 496 4095496 Total: 12402664 7847880 4554784 Current Disk Usage Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 898G 307G 546G 36% / /dev/sda1 99M 19M 76M 20% /boot none 4.0G 0 4.0G 0% /dev/shm /var/tmpMnt 4.0G 1.8G 2.0G 48% /tmp

  • What's the best-practice way to update an Adapter's underlying data?

    - by skyler
    I'm running into an IllegalStateException updating an underlying List to an Adapter (might be an ArrayAdapter or an extension of BaseAdapter, I don't remember). I do not have or remember the text of the exception at the moment, but it says something to the effect of the List's content changing without the Adapter having been notified of the change. This List /may/ be updated from another thread other than the UI thread (main). After I update this list (adding an item), I call notifyDataSetChanged. The issue seems to be that the Adapter, or ListView attached to the Adapter attempts to update itself before this method is invoked. When this happens, the IllegalStateException is thrown. If I set the ListView's visibility to GONE before the update, then VISIBLE again, no error occurs. But this isn't always practical. I read somewhere that you cannot modify the underlying this from another thread--this would seem to limit an MVC pattern, as with this particular List, I want to add items from different threads. I assumed that as long as I called notifyDataSetChanged() I'd be safe--that the Adapter didn't revisit the underlying List until this method was invoked but this doesn't seem to be the case. I suppose what I'm asking is, can it be safe to update the underlying List from threads other than the UI? Additionally, if I want to modify the data within an Adapter, do I modify the underlying List or the Adapter itself (via its add(), etc. methods). Modifying the data through the Adapter seems wrong. I came across a thread on another site from someone who seems to be having a similar problem to mine: http://osdir.com/ml/Android-Developers/2010-04/msg01199.html (this is from where I grabbed the Visibility.GONE and .VISIBLE idea). To give you a better idea of my particular problem, I'll describe a bit of how my List, Adapter, etc. are set up. I've an object named Queue that contains a LinkedList. Queue extends Observable, and when things are added to its internal list through its methods, I call setChanged() and notifyListeners(). This Queue object can have items added or removed from any number of threads. I have a single "queue view" Activity that contains an Adapter. This Activity, in its onCreate() method, registers an Observer listener to my Queue object. In the Observer's update() method I call notifyDataSetChanged() on the Adapter. I added a lot of log output and determined that when this IllegalStateExcption occurs that my Observer callback was never invoked. So it's as if the Adapter noticed the List's change before the Observer had a chance to notify its Observers, and call my method to notify the Adapter that the contents had changed. So I suppose what I'm asking is, is this a good way to rig-up an Adapter? Is this a problem because I'm updating the Adapter's contents from a thread other than the UI thread? If this is the case, I may have a solution in mind (give the Queue object a Handler to the UI thread when it's created, and make all List modifications using that Handler, but this seems improper). I realize that this is a very open-ended post, but I'm a bit lost on this and would appreciate any comments on what I've written.

  • Push notification not received in ios5 device

    - by Surender Rathore
    I am sending push notification on device which has iOS 5.0.1, but notification is not received on iOS5 device. If i try to send notification on iOS4.3.3 device, it received on this device. My server is developed in c# and apple push notification certificate is used in .p12 format. My code to register the notification is - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. // Set the navigation controller as the window's root view controller and display. deviceToken = nil; self.window.rootViewController = self.navigationController; [self.window makeKeyAndVisible]; [[UIApplication sharedApplication] enabledRemoteNotificationTypes]; [[UIApplication sharedApplication] registerForRemoteNotificationTypes: UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert]; return YES; } - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken { UIAlertView *alertView=[[UIAlertView alloc]initWithTitle:@"Succeeded in registering for APNS" message:@"Sucess" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alertView show]; [alertView release]; deviceToken = [devToken retain]; NSMutableString *dev = [[NSMutableString alloc] init]; NSRange r; r.length = 1; unsigned char c; for (int i = 0; i < [deviceToken length]; i++) { r.location = i; [deviceToken getBytes:&c range:r]; if (c < 10) { [dev appendFormat:@"0%x", c]; } else { [dev appendFormat:@"%x", c]; } } NSUserDefaults *def = [NSUserDefaults standardUserDefaults]; [def setObject:dev forKey:@"DeviceToken"]; [def synchronize]; NSLog(@"Registered for APNS %@\n%@", deviceToken, dev); [dev release]; } - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error { NSLog(@"Failed to register %@", [error localizedDescription]); UIAlertView *alertView=[[UIAlertView alloc]initWithTitle:@"FAILED" message:@"Fail" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alertView show]; [alertView release]; deviceToken = nil; } - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo { NSLog(@"Recieved Remote Notification %@", userInfo); NSDictionary *aps = [userInfo objectForKey:@"aps"]; NSDictionary *alert = [aps objectForKey:@"alert"]; //NSString *actionLocKey = [alert objectForKey:@"action-loc-key"]; NSString *body = [alert objectForKey:@"body"]; // NSMutableArray *viewControllers = [NSMutableArray arrayWithArray:[self.navigationController viewControllers]]; // // if ([viewControllers count] > 2) { // NSRange r; // r.length = [viewControllers count] - 2; // r.location = 2; // [viewControllers removeObjectsInRange:r]; // // MapViewController *map = (MapViewController*)[viewControllers objectAtIndex:1]; // [map askDriver]; // } // // [self.navigationController setViewControllers:viewControllers]; // [viewControllers release]; //NewBooking,"BookingId",Passenger_latitude,Passenger_longitude,Destination_latitude,Destination_longitude,Distance,Time,comments NSArray *arr = [body componentsSeparatedByString:@","]; if ([arr count]>0) { MapViewController *map = (MapViewController*)[[self.navigationController viewControllers] objectAtIndex:1]; [map askDriver:arr]; [self.navigationController popToViewController:[[self.navigationController viewControllers] objectAtIndex:1] animated:YES]; } //NSString *sound = [userInfo objectForKey:@"sound"]; //UIAlertView *alertV = [[UIAlertView alloc] initWithTitle:actionLocKey // message:body delegate:nil // cancelButtonTitle:@"Reject" // otherButtonTitles:@"Accept", nil]; // // [alertV show]; // [alertV release]; } Can anyone help me out with this issue.

  • How do you send a named pipe string from umnanaged to managed code space?

    - by billmcf
    I appear to have a named pipes 101 issue. I have a very simple set up to connect a simplex named pipe transmitting from a C++ unmanaged app to a C# managed app. The pipe connects, but I cannot send a "message" through the pipe unless I close the handle which appears to flush the buffer and pass the message through. It's like the message is blocked. I have tried reversing the roles of client/server and invoking them with different Flag combinations without any luck. I can easily send messages in the other direction from C# managed to C++ unmanaged. Does anyone have any insight. Can any of you guys successfully send messages from C++ unmanaged to C# managed? I can find plenty of examples of intra amanged or unmanaged pipes but not inter managed to/from unamanged - just claims to be able to do it. In the listings, I have omitted much of the wrapper stuff for clarity. The key bits I believe that are relevant are the pipe connection/creation/read and write methods. Don't worry too much about blocking/threading here. C# Server side // This runs in its own thread and so it is OK to block private void ConnectToClient() { // This server will listen to the sending client if (m_InPipeStream == null) { m_InPipeStream = new NamedPipeServerStream("TestPipe", PipeDirection.In, 1); } // Wait for client to connect to our server m_InPipeStream.WaitForConnection(); // Verify client is running if (!m_InPipeStream.IsConnected) { return; } // Start listening for messages on the client stream if (m_InPipeStream != null && m_InPipeStream.CanRead) { ReadThread = new Thread(new ParameterizedThreadStart(Read)); ReadThread.Start(m_InPipeStream); } } // This runs in its own thread and so it is OK to block private void Read(object serverObj) { NamedPipeServerStream pipeStream = (NamedPipeServerStream)serverObj; using (StreamReader sr = new StreamReader(pipeStream)) { while (true) { string buffer = "" ; try { // Blocks here until the handle is closed by the client-side!! buffer = sr.ReadLine(); // <<<<<<<<<<<<<< Sticks here } catch { // Read error break; } // Client has disconnected? if (buffer == null || buffer.Length == 0) break; // Fire message received event if message is non-empty if (MessageReceived != null && buffer != "") { MessageReceived(buffer); } } } } C++ client side // Static - running in its own thread. DWORD CNamedPipe::ListenForServer(LPVOID arg) { // The calling app (this) is passed as the parameter CNamedPipe* app = (CNamedPipe*)arg; // Out-Pipe: connect as a client to a waiting server app->m_hOutPipeHandle = CreateFile("\\\\.\\pipe\\TestPipe", GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); // Could not create handle if (app->m_hInPipeHandle == NULL || app->m_hInPipeHandle == INVALID_HANDLE_VALUE) { return 1; } return 0; } // Sends a message to the server BOOL CNamedPipe::SendMessage(CString message) { DWORD dwSent; if (m_hOutPipeHandle == NULL || m_hOutPipeHandle == INVALID_HANDLE_VALUE) { return FALSE; } else { BOOL bOK = WriteFile(m_hOutPipeHandle, message, message.GetLength()+1, &dwSent, NULL); //FlushFileBuffers(m_hOutPipeHandle); // <<<<<<< Tried this return (!bOK || (message.GetLength()+1) != dwSent) ? FALSE : TRUE; } } // Somewhere in the Windows C++/MFC code... ... // This write is non-blocking. It just passes through having loaded the pipe. m_pNamedPipe->SendMessage("Hi de hi"); ...
