  • Run an ActiveX through Web

    - by balexandre
    We have a webpage that works fine on the local computer as it uses a COM Object that is only available in the local computer. the program generates HTML code: <html> <head> <script type="text/javascript"> <!-- function ResizeControl(){Y = document.body.clientHeight;if (Y < 1) {Y = 1}X = document.body.clientWidth;if (X < 1) {X = 1}ActiveX.width = X;ActiveX.height = Y} --> </script> <style type="text/css">html, body { overflow:hidden; } </style> </head> <body OnResize="ResizeControl()" OnLoad="ResizeControl()" leftmargin="0" topmargin="0" rightmargin="0" bottommargin="0"> <object id="ActiveX" classid="CLSID:8EC68701-329D-4567-BCB5-9EE4BA43D358" width="14" height="14"> <PARAM NAME="tabName" VALUE="Complaints"> </object> </body> </html> and shows fine My question is, How can we port this into a web environment? As the Delphi developer has no idea and I'm not a Delphi fellow. I want to be able to use this "webpage" on a web address http://INTRANET/mysite/thispage.html Any idea, any though, any door to open is greatly appreciate :)

  • Managing/Storing complex application form

    - by mickyjtwin
    I am developing an online application form, which can be of two categories, either domestic/international. Each different type has commong questions, and also specific questions. They are approx 6 pages/steps of questions. The application form can also be saved at the end of each step, and can be completed at a later date. Some questions will vary depending on answers to previous questions, so there are some complex business rules. In terms of storage of results, would it be best to store the answers in and XML field in SQL? What would be the best way to reference a question to an answer. There is no need for the form to be dynamic in rendering questions etc. e.g. <Application id="123" type="Domestic"> <Answers> <EmailAddress>[email protected]</EmailAddress> <HomePhone>555-5555</HomePhone> <Suburb>MySuburb</Suburb> <Guardians> <Guardian type="Mother"> <FirstName>Mom</FirstName> </Guardian> </Guardians> <Answers> </Application>

  • Rolling Back a Transaction with MySQL Connector in VB.net

    - by Jonathan
    Hey all- I have one multi-row INSERT statement (300 or so sets of values) that I would like to commit to the MySQL database in an all-or-nothing fashion. insert into table VALUES (1, 2, 3), (4, 5, 6), (7, 8, 9); In some cases, a set of values in the command will not meet the criteria of the table (duplicate key, for example). When that happens I do not want any of the previous sets added to the database. I've implemented this with the following code, however, my rollback command doesn't appear to be making a difference. I've used this documentation: http://dev.mysql.com/doc/refman/5.0/es/connector-net-examples-mysqltransaction.html Dim transaction As MySqlTransaction = sqlConnection.BeginTransaction() sqlCommand = New MySqlCommand(insertStr, sqlConnection, transaction) Try sqlCommand.ExecuteNonQuery() Catch ex As Exception writeToLog("EXCEPTION: " & ex.Message & vbNewLine) writeToLog("Could not execute " & sqlCmd & vbNewLine) Try transaction.Rollback() writeToLog("All statements were rolled back." & vbNewLine) Return False Catch rollbackEx As Exception writeToLog("EXCEPTION: " & rollbackEx.Message & vbNewLine) writeToLog("All statements were not rolled back." & vbNewLine) Return False End Try End Try transaction.commit() I get the DUPLICATE KEY exception thrown, no Rollback Exception thrown, and every set of values up to duplicate key committed to the database. What am I doing wrong? Thanks- Jonathan

  • Troubleshooting FORM POST problems

    - by brettr
    I'm using the following code to submit to a WCF service. I keep getting an error that the key is invalid. I have a webpage on the same server that I submit the same data (but different key) using a FORM POST. It works fine that way. I put the URL below all in a URL (including valid key from server webpage) and get the key is invalid error. I'm thinking the data I'm submitting through the iPhone isn't really going across as a FORM POST but rather as a URL. Is there anything I may be doing wrong in the following code or any other suggestions? NSString *stringForURL = @"https://abc.com/someservice.aspx"; NSURL *URL=[[NSURL alloc] initWithString:stringForURL]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL]; NSString *request_body = [NSString stringWithFormat:@"prop1=value1&key=%@", [@"r2xHEuzgDTQEWA5Xe6+k9BSVrgsMX2mWQBW/39nqT4s=" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; NSData *postData = [request_body dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setHTTPMethod:@"POST"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; [NSThread sleepForTimeInterval:1]; self.receivedData = [[NSMutableData data] retain];

  • Retrieve a list of the most popular GET param variations for a given URL?

    - by jamtoday
    I'm working on building intelligence around link propagation, and because I need to deal with many short URL services where a reverse-lookup from an exact URL address is required, I need to be able to resolve multiple approximate versions of the same URL. An example would be a URL like http://www.example.com?ref=affil&hl=en&ct=0 Of course, changing GET params in certain circumstances can refer to a completely different page, especially if the GET params in question refer to a profile or content ID. But a quick parse of the page would quickly determine how similar the pages were to each other. Using a bit of machine learning, it could quickly become clear which GET params don't effect the content of the pages returned for a given site. I'm assuming a service to send a URL and get a list of very similar URLs could only be offered by the likes of Google or Yahoo (or Twitter), but they don't seem to offer this feature, and I haven't found any other services that do. If you know of any services that do cluster together groups of almost identical URLs in the aforementioned way, please let me know. My bounty is a hug.

  • Windows Batch file to echo a specific line number

    - by Lee
    So for the second part of my current dilemma, I have a list of folders in c:\file_list.txt. I need to be able to extract them (well, echo them with some mods) based on the line number because this batch script is being called by an iterative macro process. I'm passing the line number as a parameter. @echo off setlocal enabledelayedexpansion set /a counter=0 set /a %%a = "" for /f "usebackq delims=" %%a in (c:\file_list.txt) do ( if "!counter!"=="%1" goto :printme & set /a counter+=1 ) :printme echo %%a which gives me an output of %a. Doh! So, I've tried echoing !a! (result: ECHO is off.); I've tried echoing %a (result: a) I figured the easy thing to do would be to modify the head.bat code found here: http://stackoverflow.com/questions/130116/dos-batch-commands-to-read-first-line-from-text-file except rather than echoing every line - I'd just echo the last line found. Not as simple as one might think. I've noticed that my counter is staying at zero for some reason; I'm wondering if the set /a counter+=1 is doing what I think it's doing.

  • Valueurl Binding On Large Arrays Causes Sluggish User Interface

    - by Hooligancat
    I have a large data set (some 3500 objects) that returns from a remote server via HTTP. Currently the data is being presented in an NSCollectionView. One aspect of the data is a path pack to the server for a small image that represents the data (think thumbnail for simplicity). Bindings works fantastically for the data that is already returned, and binding the image via a valueurl binding is easy to do. However, the user interface is very sluggish when scrolling through the data set - which makes me think that the NSCollectionView is retrieving all the image data instead of just the image data used to display the currently viewable images. I was under the impression that Cocoa controls were smart enough to only retrieve data for the information that is actually being output to the user interface through lazy loading. This certainly seems to be the case with NSTableView - but I could be misguided on this thought. Should valueurl binding act lazily and, moreover, should it act lazily in an NSCollectionView? I could create a caching mechanism (in fact I already have such a thing in place for another application - see my post here if you are interested http://stackoverflow.com/questions/1740209/populating-nsimage-with-data-from-an-asynchronous-nsurlconnection) but I really don't want to go this route if I don't have to for this specific implementation as the user could potentially change data sets often and may only want small sub-sets of the data. Any suggested approaches? Thanks!

  • How to feature-detect/test for specific jQuery (and Javascript) methods/functions used

    - by Zildjoms
    good day everyone, hope yer all doin awesome am very new to javascript and jquery, and i (think) i have come up with a simple fade-in/out implementation on a site am workin on (check out http://www.s5ent.com/expandjs.html - if you have the time to check it for inefficiency or what that'd be real sweet). i use the following functions/methods/collections and i would like to do a feature test before using them. uhm.. how? or is there a better way to go about this? jQuery $ .fadeIn([duration]) .fadeOut([duration]) .attr(attributeName,value) .append(content) .each(function(index,Element)) .css(propertyName,value) .hover(handlerIn(eventObject),handlerOut(eventObject)) .stop([clearQueue],[jumpToEnd]) .parent() .eq(index) JavaScript setInterval(expression,timeout) clearInterval(timeoutId) setTimeout(expression,timeout) clearTimeout(timeoutId) i tried looking into jquery.support for the jquery ones, but i find myself running into conceptual problems with it, i.e. for fadein/fadeout, i (think i) should test for $.support.opacity, but that would be false in ie whereas ie6+ could still fairly render the fades. also am using jquery 1.2.6 coz that's enough for what i need. the support object is in 1.3. so i'm hoping to avoid dragging-in more unnecessary code if i can. i also worked with browser sniffing, no matter how frowned-upon. but that's also a bigger problem for me because of non-standard ua strings and spoofing and everything else am not aware of. so how do you guys think i should go about this? or should i even? is there a better way to go about making sure that i don't run code that'll eventually break the page? i've set it up to degrade into a css hover when javascript ain't there.. expertise needed. much appreciated, thanks guyz!

  • web development using google sites

    - by CHID
    Hi, I have hosted a website. But now my client asks to change it to http://sites.google.com. They hav registered their domain in google. I logged in the site and saw the procedures to create a website from scratch. But is there any way to directly replace the site into google sites. Like, in my site i hav included css files in a folder called stylesheets/css and access it through the link tag. And there are several folders lik that, viz images, scripts etc. 1.Now if i have to transfer it to google sites, where do i create the folders and stuff. I have the priviliges to login to the admin part of the site. 2.And also is there anyway to create database and access it in google sites? 3.Also i see that only html pages can be created. Is there a way to add php pages or other scripting languages? 4.Going forward will google sites be usefull for professional web designing. pls give ideas on whether or not google sites is a good idea to go with

  • why unsigned int 0xFFFFFFFF is equal to int -1?

    - by conejoroy
    perhaps it's a very stupid question but I'm having a hard time figuring this out =) in C or C++ it is said that the maximum number a size_t (an unsigned int data type) can hold is the same as casting -1 to that data type. for example see http://stackoverflow.com/questions/1420982/invalid-value-for-sizet Why?? I'm confused.. I mean, (talking about 32 bit ints) AFAIK the most significant bit holds the sign in a signed data type (that is, bit 0x80000000 to form a negative number). then, 1 is 0x00000001.. 0x7FFFFFFFF is the greatest positive number a int data type can hold. then, AFAIK the binary representation of -1 int should be 0x80000001 (perhaps I'm wrong). why/how this binary value is converted to anything completely different (0xFFFFFFFF) when casting ints to unsigned?? or.. how is it possible to form a binary -1 out of 0xFFFFFFFF? I have no doubt that in C: ((unsigned int)-1) == 0xFFFFFFFF or ((int)0xFFFFFFFF) == -1 is equally true than 1 + 1 == 2, I'm just wondering why. thanks!

  • Problems with jQuery plugin Tablesorter 2.0

    - by gunther-von-goetzen-sanchez
    I downloaded the jQuery plugin Tablesorter 2.0 from http://tablesorter.com/jquery.tablesorter.zip and modified the example-pager.html which is in tablesorter/docs directory I wrote additional Rollover effects: $(function() { $("table") .tablesorter({widthFixed: true, widgets: ['zebra']}) .tablesorterPager({container: $("#pager")}); $("tr").mouseover(function () { $(this).addClass('over'); }); $("tr").mouseout(function () { $(this).removeClass('over'); }); $("tr").click(function () { $(this).addClass('marked'); }); $("tr").dblclick(function () { $(this).removeClass('marked'); }); }); And of course modified the themes/blue/style.css file: /* Additional code */ table.tablesorter tbody tr.odd td { background-color: #D1D1F0; } table.tablesorter tbody tr.even td { background-color: #EFDEDE; } table.tablesorter tbody tr.over td { background-color: #FBCA33; } table.tablesorter tbody tr.marked td { background-color: #FB4133; } /* Additional code END*/ All this works fine BUT when I go to further pages i.e. page 2 3 or 4 the effects are gone!

  • Layering Cocoa WebView - Drawing on top?

    - by Josh
    http://stackoverflow.com/questions/1618498/webview-in-core-animation-layer The only other thread I can find is the above which doesn't necessarily fit my needs. Is there a reliable way to simply draw a view on top of a webview? I've tried to layer a regular NSView on top of WebView, and it draws right at first, but any movement in the webview (scrolling the page etc) appears to invalidate the view and produces visual artifacts. I've tried: [[[NSApp mainWindow] contentView] addSubview:view positioned:NSWindowAbove relativeTo:webView]; No luck there, same problems -- z-ordering doesn't seem to work unless I'm missing something. Is this just a limitation of webviews? I also tried implementing the view above as a window, which worked much better (just controlled the location of the window programmatically). However, the desired behavior is for the user to enter some text into this window, but for it not to steal "focus" -- ie the main window goes inactive (the x - + go gray) when the user clicks on the text field in the new window. Any way to avoid that? I've tried subclassing NSWindow and overriding canBecomeKey (return YES) and canBecomeMain (return NO) but the window still steals focus. Josh

  • PHP OOP: Providing Domain Entities with "Identity"

    - by sunwukung
    Bit of an abstract problem here. I'm experimenting with the Domain Model pattern, and barring my other tussles with dependencies - I need some advice on generating Identity for use in an Identity Map. In most examples for the Data Mapper pattern I've seen (including the one outlined in this book: http://apress.com/book/view/9781590599099) - the user appears to manually set the identity for a given Domain Object using a setter: $UserMapper = new UserMapper; //returns a fully formed user object from record sets $User = $UserMapper->find(1); //returns an empty object with appropriate properties for completion $UserBlank = $UserMapper->get(); $UserBlank->setId(); $UserBlank->setOtherProperties(); Now, I don't know if I'm reading the examples wrong - but in the first $User object, the $id property is retrieved from the data store (I'm assuming $id represents a row id). In the latter case, however, how can you set the $id for an object if it has not yet acquired one from the data store? The problem is generating a valid "identity" for the object so that it can be maintained via an Identity Map - so generating an arbitrary integer doesn't solve it. My current thinking is to nominate different fields for identity (i.e. email) and demanding their presence in generating blank Domain Objects. Alternatively, demanding all objects be fully formed, and using all properties as their identity...hardly efficient. (Or alternatively, dump the Domain Model concept and return to DBAL/DAO/Transaction Scripts...which is seeming increasingly elegant compared to the ORM implementations I've seen...)

  • Dojo dialog, the iPad and the virtual keyboard issue

    - by Chris Butler
    Recently, I have been working on a project where the interface should work for desktop and tablets (in particular the iPad). One issue I am coming across is with a Dojo dialog on the iPad when text entry is taking place. Basically here is what happens: Load Dojo interface with buttons on iPad - OK Press button (touch) to show dialog (90% height and width) - OK Click on text box (touch) like DateTextBox or TimeTextBox - OK, the virtual keyboard is opened Click the date or time I want in the UI (touch) - OK, but I can't see all of the options since it is longer than the screen size... Try to scroll down (swipe up with two fingers or click 'next' in the keyboard) - not OK and the dialog repositions itself to have it's top at the top of the viewport area. Basically, the issue is that the dialog keeps trying to reposition itself. Am I able to stop dialog resizing and positioning if I catch the window onResize events? Does anyone else have this issue with the iPad and Dojo dialogs? Also, I found this StackOverflow topic on detecting the virtual keyboard, but it wasn't much help in this case... http://stackoverflow.com/questions/2593139/ipad-web-app-detect-virtual-keyboard-using-javascript-in-safari Thanks!

  • Problem when reading input in C

    - by gcx
    I've made a Linked List. Its elements keep both previous and next items' address. It gets commands from an input file. It detects the command and uses the following statement as a parameter. (text: add_to_front john - means: add_to_front(john)) Code: http://pastebin.com/KcAm1y3L When I try to give the commands from an input file it gives me same output over and over. However, if I write inputs in main() manually, it works. For ex input file: add_to_front john add_to_back jane add_to_back jane print (unfortunately) the output is: >add_to_front john >add_to_back jane >add_to_back jane >print jane jane jane Although, if I write add_to_front(john); add_to_back(jane); add_to_back(jane); print(); instead of this command check: while (scanf("%s",command)!=EOF) { if (strcmp(command,"add_to_front")==0) { gets(parameter); add_to_front(parameter); } else if (strcmp(command,"add_to_back")==0) { gets(parameter); add_to_back(parameter); } else if (strcmp(command,"remove_from_back")==0) remove_from_back(parameter); ... printf(" HUH?\n"); } } in main() it gives the correct output. I know it's a lot to ask but this thing is bothering me for 2 days. What do you think i'm doing wrong?

  • Unpacking gems [Rails 2.3.5]

    - by yuval
    I have the following gems defined in my environment.rb file: config.gem "authlogic" config.gem "paperclip" config.gem "pauldix-feedzirra", :lib => "feedzirra", :source => "http://gems.github.com" config.gem 'whenever', :lib => false, :source => 'http://gemcutter.org/' I have them installed on my local computer and everything is working well. Since I am working on a shared-server (DreamHost), I need to unpack those gems to get them to work (can't install them as I did on my own computer to get them to work). Before uploading, I ran the following on my local machine: rake gems:unpack This created the following folders in /vender/gems: authlogic-2.1.3, paperclip-2.3.1.1, pauldix-feedzirra-0.0.18, whenever-0.4.1 So it looks like they're all there. When I run rake db:migrate on the server, though, I get these following error: Missing these required gems: pauldix-feedzirra For some reason, the feedzirra unpacked gem is not detected. Could anybody give me a clue as to why this is happening and how to solve it? Thanks!

  • Why Won't this http post request work?

    - by dubbeat
    Hi, I'm wondering why this http post request won't work for my iphone app. I know for a fact that the url is correct and that the variables I'm sending are correct but for some reason the request is not being recieved by the aspx page. NSMutableString *httpBodyString; NSURL *url; NSMutableString *urlString; httpBodyString=[NSMutableString stringWithFormat:@"%@%@%@%@%@",@"?g=",promoValueObject.country,@"&c=",promoData.artistid,@"&d=iphone"]; urlString=[[NSMutableString alloc] initWithString:@"http://www.mysite.com/stats_promo.aspx"]; url=[[NSURL alloc] initWithString:urlString]; [urlString release]; NSMutableURLRequest *urlRequest=[NSMutableURLRequest requestWithURL:url]; [url release]; [urlRequest setHTTPMethod:@"POST"]; [urlRequest setHTTPBody:[httpBodyString dataUsingEncoding:NSISOLatin1StringEncoding]]; //[httpBodyString release]; NSURLConnection *connectionResponse = [[NSURLConnection alloc] initWithRequest:urlRequest delegate:self]; if (!connectionResponse) { NSLog(@"Failed to submit request"); } else { NSLog(@"--------- Request submitted ---------"); NSLog(@"connection: %@ method: %@, encoded body: %@, body: %a", connectionResponse, [urlRequest HTTPMethod], [urlRequest HTTPBody], httpBodyString); }

  • Problem with ActionScript 3.0 button to URL and root movieclip

    - by aarontb
    Okay, so, here's what the problem is. I'm creating a flash site with each page being it's own movieclip and Scene 1 being the menu and other things that stay on the site. I've created a MovieClip called 'HowWorksScene'. The movieclip has 2 buttons that link out to different URLs, however, I'm sure that when 1 of the button scripts work, the same script will work for the other...so here's the problem that I'm having with the Button stop(); VidDemo_btn.addEventListener(MouseEvent.CLICK, video); function video(event:MouseEvent):void { var link:URLRequest = new URLRequest('www.youtube.com'); navigateToURL(link); } Problem is that I cannot GET to that frame to even determine an error. The problem preventing me from getting to this point is a call function. In the "HomePage" movieclip, when the button is pressed to go to the next scene, "Homepage" fades out and flys left then the next frame is 1 frame but activates the next movieclipe "HowWorksScene"...but without errors, it simply goes to frame 17 of "Homepage". I've tried doing _root.gotoAndPlay(17); but get an undefined error. So, I guess my question is: What is the BEST way to direct from within a movieclip to a frame in the parent Scene? I've even tried using gotoAndPlay(17, "Scene 1"); And that still did not work. Please let me know ASAP!

  • TranslateTransform for drag and drop in Silverlight

    - by fuzzyman
    We're trying to implement drag and drop in Silverlight (3). We want users to be able to drag elements from a treeview onto another part of a UI. The parent element is a Grid, and we've been trying to use a TranslateTransform along with the MouseLeftButtonDown, MouseMove (etc) events, as recommended by various online examples. For example: http://www.85turns.com/2008/08/13/drag-and-drop-silverlight-example/ We're doing this in IronPython, but that should be more or less irrelevant. The drag start is correctly initiated, but the item we are dragging appears in the 'wrong' location (offset a few hundred pixels to the right and down from the cursor) and I can't for the life of me work out why. Basic xaml: <Grid x:Name="layout_root"> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition Height="120"/> </Grid.RowDefinitions> <Border x:Name="drag" Background="LightGray" Width="40" Height="15" Visibility="Collapsed" Canvas.ZIndex="10"> <Border.RenderTransform> <TranslateTransform x:Name="transform" X="0" Y="0" /> </Border.RenderTransform> <TextBlock x:Name="dragText" TextAlignment="Center" Foreground="Gray" Text="foo" /> </Border> ... </Grid> The startDrag method is triggered by the MouseLeftButtonDown event (on a TextBlock in a TreeViewItem.Header). onDrag is triggered by MouseMove. In the following code self.root is Application.Current.RootVisual (top level UI element from app.xaml): def startDrag(self, sender, event): self.root.drag.Visibility = Visibility.Visible self.root.dragText.Text = sender.Text position = event.GetPosition(self.root.drag.Parent) self.root.drag.transform.X = position.X self.root.drag.transform.Y = position.Y self.root.CaptureMouse() self._captured = True def onDrag(self, sender, event): if self._captured: position = event.GetPosition(self.root.drag.Parent) self.root.drag.transform.X = position.X self.root.drag.transform.Y = position.Y The dragged item follows the mouse move, but is offset considerably. Any idea what I am doing wrong and how to correct it?
