  • TinyMCE + jQuery + custom plugin = tinymce is undefined?

    - by user368691
    The problem occurs when I try to create small plugin to allow me toggle on and off WYSIWYG on all textareas in the website. //$('form.default textarea').each(function(){ // console.log( $('<a href="#">Enable WYSIWYG editor</a>').insertAfter('form.default textarea').prev('textarea.wysiwyg').tinymce().hide() ); //}); The full (a bit simplified) code looks like this: $('textarea.wysiwyg').tinymce({ skin : 'cirkuit', theme : 'advanced', plugins : 'pagebreak,style,layer,advlink,inlinepopups,contextmenu,paste,directionality,noneditable,nonbreaking,xhtmlxtras,template', // Theme options theme_advanced_buttons1 : 'formatselect,fontsizeselect,forecolor,|,bold,italic,strikethrough,|,bullist,numlist,|,justifyleft,justifycenter,justifyright,|,link,unlink,|,image,|,code,paste,pastetext,pasteword,removeformat,|,backcolor,|,underline,justifyfull,sup,|,outdent,indent,|,hr,charmap,|,undo,redo', theme_advanced_buttons2 : '', theme_advanced_buttons3 : '', theme_advanced_toolbar_location : 'top', theme_advanced_toolbar_align : 'left', theme_advanced_statusbar_location: 'bottom', theme_advanced_resizing : true, theme_advanced_resize_horizontal : false, height : 500, theme_advanced_resizing_min_height : 500, document_base_url : 'http://static.<?=$settings['system_host']?>/' }); $('textarea.wysiwyg').each(function() { $(this).tinymce().hide(); }); What is the error? FireBug says that tinymce() in undefined; this message occurs in each() loop. Thus, tinymce() is actually initialized. I am really lost towards, what could be causing this.

  • SQL MIN in Sub query causes huge delay

    - by Spencer
    I have a SQL query that I'm trying to debug. It works fine for small sets of data, but in large sets of data, this particular part of it causes it to take 45-50 seconds instead of being sub second in speed. This subquery is one of the select items in a larger query. I'm basically trying to figure out when the earliest work date is that fits in the same category as the current row we are looking at (from table dr) ISNULL(CONVERT(varchar(25),(SELECT MIN(drsd.DateWorked) FROM [TableName] drsd WHERE drsd.UserID = dr.UserID AND drsd.Val1 = dr.Val1 OR (((drsd.Val2 = dr.Val2 AND LEN(dr.Val2) > 0) AND (drsd.Val3 = dr.Val3 AND LEN(dr.Val3) > 0) AND (drsd.Val4 = dr.Val4 AND LEN(dr.Val4) > 0)) OR (drsd.Val5 = dr.Val5 AND LEN(dr.Val5) > 0) OR ((drsd.Val6 = dr.Val6 AND LEN(dr.Val6) > 0) AND (drsd.Val7 = dr.Val7 AND LEN(dr.Val2) > 0))))), '') AS WorkStartDate, This winds up executing a key lookup some 18 million times on a table that has 346,000 records. I've tried creating an index on it, but haven't had any success. Also, selecting a max value in this same query is sub second in time, as it doesn't have to execute very many times at all. Any suggestions of a different approach to try? Thanks!

  • MySQL Connection Timeout Issue - Grails Application on Tomcat using Hibernate and ORM

    - by gav
    Hi Guys I have a small grails application running on Tomcat in Ubuntu on a VPS. I use MySql as my datastore and everything works fine unless I leave the application for more than half a day (8 hours?). I did some searching and apparently this is the default wait_timeout in mysql.cnf so after 8 hours the connection will die but Tomcat won't know so when the next user tries to view the site they will see the connection failure error. Refreshing the page will fix this but I want to get rid of the error altogether. For my version of MySql (5.0.75) I have only my.cnf and it doesn't contain such a parameter, In any case changing this parameter doesn't solve the problem. This Blog Post seems to be reporting a similar error but I still don't fully understand what I need to configure to get this fixed and also I am hoping that there is a simpler solution than another third party library. The machine I'm running on has 256MB ram and I'm trying to keep the number of programs/services running to a minimum. Is there something I can configure in Grails / Tomcat / MySql to get this to go away? Thanks in advance, Gav From my Catalina.out; 2010-04-29 21:26:25,946 [http-8080-2] ERROR util.JDBCExceptionReporter - The last packet successfully received from the server was 102,906,722 milliseconds$ 2010-04-29 21:26:25,994 [http-8080-2] ERROR errors.GrailsExceptionResolver - Broken pipe java.net.SocketException: Broken pipe at java.net.SocketOutputStream.socketWrite0(Native Method) ... 2010-04-29 21:26:26,016 [http-8080-2] ERROR util.JDBCExceptionReporter - Already closed. 2010-04-29 21:26:26,016 [http-8080-2] ERROR util.JDBCExceptionReporter - Already closed. 2010-04-29 21:26:26,017 [http-8080-2] ERROR servlet.GrailsDispatcherServlet - HandlerInterceptor.afterCompletion threw exception org.hibernate.exception.GenericJDBCException: Cannot release connection at java.lang.Thread.run(Thread.java:619) Caused by: java.sql.SQLException: Already closed. at org.apache.commons.dbcp.PoolableConnection.close(PoolableConnection.java:84) at org.apache.commons.dbcp.PoolingDataSource$PoolGuardConnectionWrapper.close(PoolingDataSource.java:181) ... 1 more

  • Why is software quality so problematic?

    - by Yuval A
    Even when viewing the subject in the most objective way possible, it is clear that software, as a product, generally suffers from low quality. Take for example a house built from scratch. Usually, the house will function as it is supposed to. It will stand for many years to come, the roof will support heavy weather conditions, the doors and the windows will do their job, the foundations will not collapse even when the house is fully populated. Sure, minor problemsdo occur, like a leaking faucet or a bad paint job, but these are not critical. Software, on the other hand is much more susceptible to suffer from bad quality: unexpected crashes, erroneous behavior, miscellaneous bugs, etc. Sure, there are many software projects and products which show high quality and are very reliable. But lots of software products do not fall in this category. Take into consideration paradigms like TDD which its popularity is on the rise in the past few years. Why is this? Why do people have to fear that their software will not work or crash? (Do you walk into a house fearing its foundations will collapse?) Why is software - subjectively - so full of bugs? Possible reasons: Modern software engineering exists for only a few decades, a small time period compared to other forms of engineering/production. Software is very complicated with layers upon layers of complexity, integrating them all is not trivial. Software development is relatively easy to start with, anyone can write a simple program on his PC, which leads to amateur software leaking into the market. Tight budgets and timeframes do not allow complete and high quality development and extensive testing. How do you explain this issue, and do you see software quality advancing in the near future?

  • Writing an efficient cron job script utilizing Zend_Mail_Storage_Imap.

    - by fireeyedboy
    I'm new to the IMAP protocol and Zend_Mail_Storage and I'm writing a small php script for a cron job that should regularly poll an IMAP account and check for new messages, and send an e-mail if new messages have arrived. As you can imagine, I want to only poll the IMAP account for relevant messages, and I only want to send a new e-mail if new messages have arrived since the last polled new message. So I thought of keeping track of the last message I polled with some unique identifier for a message. But I'm a bit uncertain about whether the methods I want to utilize for this do what I expect them to do though. So my questions are: Does the iterator position of Zend_Mail_Storage_Imap actually resemble some IMAP unique identifier for messages, or is it simply only and internal position of Zend_Mail_Storage_Abstract? For instance, if I tell it to seek() to message 5 (which I stored from an earlier session) will it indeed seek to the appropriate message on the IMAP server, even if for instance messages have been deleted since last session? Would keeping track of this latest polled message id in a file suffice for a cron job that, say, polls the account every 5 or 10 minutes? Or is this too naive, and should I be using a database for instance. Or is there maybe a much easier way to keep track of such state with Zend_Mail_Storage_Abstract? Also, do I need to poll every IMAP folder? Or is everything accumulated when I poll INBOX? If you could shed some light on any of these matters, I'ld appreciate it. Thanks in advance.

  • Passing binary blob through an Android content provider

    - by velocityb0y
    I have a content provider that is custom to my set of Android applications, and one of the things it needs to expose is a small (20-30k) byte array. The uri for these blobs looks like content://my.authority/blob/# where # is the row number; the resulting cursor has the standard _id column and a data column. I'm using a MatrixCursor in the provider's query method: byte[] byteData = getMyByteData(); MatrixCursor mc = new MatrixCursor(COLUMNS); mc.addRow(new Object[] { id, byteData }); Later, in the application consuming the data, I do Cursor c = managedQuery(uri, null, null, null, null); c.moveToFirst(); byte[] data = c.getBlob(c.getColumnIndexOrThrow("data")); However, data does not contain the contents of my original byte array; rather, it contains something like "[B@435cc518", which looks more like the address of the array than the contents. I tried wrapping the byte array in an implementation of java.sql.Blob, figuring that it might be looking for that since the content provider subsystem was written to be easy to use with SQLite, but it didn't help. Has anyone gotten this to work? If the data was in the file system, there are methods in ContentProvider that I could use to provide a marshalled InputStream to the client, but the data I'm trying to send back lives as a resource in the content provider's APK.

  • Extra text shown on oveflow: hidden

    - by TRiG
    I'm keeping the main content area of the webpage small, so that footer navigation can be seen "above the fold". This is done by javascript setting the main content <div> thus: sec.style.height = '265px'; sec.style.overflow = 'hidden'; And then using javascript to insert a button to change the style back to normal: sec.style.height = 'auto'; The problem is that the cut-off point of 265px (dictated by the size of an image which I don't want to hide) doesn't quite match the gap between lines of text. This means that there the tops of tall letters show as funny little marks. Is there any way to hide text which is partially showing in a <div style="overflow: hidden;">? Edit to add: Full javascript var overflow = { hide: function() { var sec = app.get('content_section'); sec.style.height = '263px'; sec.style.overflow = 'hidden'; overflow.toggle(false); }, toggle: function(value) { var cnt = app.get('toggle_control'); if (value) { var func = 'hide'; cnt.innerHTML = 'Close « '; } else { var func = 'show'; cnt.innerHTML = 'More » '; } cnt.onclick = function() {eval('overflow.' + func + '();'); return false;}; cnt.style.cursor = 'pointer'; cnt.style.fontWeight = 'normal'; cnt.style.margin = '0 0 0 857px'; }, show: function() { var sec = app.get('content_section'); sec.style.height = 'auto'; overflow.toggle(true); } } if (document.addEventListener) { document.addEventListener('DOMContentLoaded', overflow.hide, false); } else { window.onload = function() {return overflow.hide();}; }

  • Why does my Net::Telnet program timeout?

  • NServiceBus Testing Framework and NAnt Issue?

    - by user344775
    Hi Guys, This is my first post here, and I'm new to NService Bus world. After play around for a couple days, and found that it's really powerful framework to creat service and easy to use. :) Now, I came across a small question. I created a project which uses NServiceBus, it got normal message handlers and Saga handlers. And also I created a couple tests around these with NServiceBus.Testing framework. It all works fine when I run the tests via ReSharper Test Runner works and NUnit console, they all works fine, but when I include them into NAnt build script, it throw the following exception: System.Reflection.ReflectionTypeLoadException : Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. at System.Reflection.Module.GetTypesInternal(StackCrawlMark& stackMark) at System.Reflection.Assembly.GetTypes() at NServiceBus.Configure.<c_DisplayClass1.b__0(Assembly a) at System.Array.ForEach[T](T[] array, Action`1 action) at NServiceBus.Configure.With(Assembly[] assemblies) at NServiceBus.Configure.With(String probeDirectory) at NServiceBus.Configure.With() at NServiceBus.Testing.Test.Initialize() Any ideas? Thanks a lot.

  • Why is the UpdatePanel Response size changing on alternate requests?

    - by Decker
    We are using UpdatePanel in a small portion of a large page and have noticed a performance problem where IE7 becomes CPU bound and the control within the UpdatePanel takes a long time (upwards of 30 seconds) to render. We also noticed that Firefox does not seem to suffer from these delays. We ran both Fiddler (for IE) and Firebug (for Firefox) and noticed that the real problem lied with the amount of data being returned in update panel responses. Within the UpdatePanel control there is a table that contains a number of ListBox controls. The real problem is that EVERY OTHER TIME the response (from making ListBox selections) alternates from 30K to 430K. Firefox handles the 400+K response in a reasonable amount of time. For whatever reason, IE7 goes CPU bound while it is presumably processing this data. So irrespective of whether or not we should be using an UpdatePanel or not, we'd like to figure out why every other async postback response is larger by a factor of more than 10 than the previous one. When the response is in the 30K range, IE updates the display within a second. On the alternate times, the response time is well over 10 times longer. Any idea why this alternating behavior should be happening with an UpdatePanel?

  • Efficient Multiple Linear Regression in C# / .Net

    - by mrnye
    Does anyone know of an efficient way to do multiple linear regression in C#, where the number of simultaneous equations may be in the 1000's (with 3 or 4 different inputs). After reading this article on multiple linear regression I tried implementing it with a matrix equation: Matrix y = new Matrix( new double[,]{{745}, {895}, {442}, {440}, {1598}}); Matrix x = new Matrix( new double[,]{{1, 36, 66}, {1, 37, 68}, {1, 47, 64}, {1, 32, 53}, {1, 1, 101}}); Matrix b = (x.Transpose() * x).Inverse() * x.Transpose() * y; for (int i = 0; i < b.Rows; i++) { Trace.WriteLine("INFO: " + b[i, 0].ToDouble()); } However it does not scale well to the scale of 1000's of equations due to the matrix inversion operation. I can call the R language and use that, however I was hoping there would be a pure .Net solution which will scale to these large sets. Any suggestions? EDIT #1: I have settled using R for the time being. By using statconn (downloaded here) I have found it to be both fast & relatively easy to use this method. I.e. here is a small code snippet, it really isn't much code at all to use the R statconn library (note: this is not all the code!). _StatConn.EvaluateNoReturn(string.Format("output <- lm({0})", equation)); object intercept = _StatConn.Evaluate("coefficients(output)['(Intercept)']"); parameters[0] = (double)intercept; for (int i = 0; i < xColCount; i++) { object parameter = _StatConn.Evaluate(string.Format("coefficients(output)['x{0}']", i)); parameters[i + 1] = (double)parameter; }

  • problem using getline with a unicode file

    - by hamishmcn
    UPDATE: Thank you to @Potatoswatter and @Jonathan Leffler for comments - rather embarrassingly I was caught out by the debugger tool tip not showing the value of a wstring correctly - however it still isn't quite working for me and I have updated the question below: If I have a small multibyte file I want to read into a string I use the following trick - I use getline with a delimeter of '\0' e.g. std::string contents_utf8; std::ifstream inf1("utf8.txt"); getline(inf1, contents_utf8, '\0'); This reads in the entire file including newlines. However if I try to do the same thing with a wide character file it doesn't work - my wstring only reads to the the first line. std::wstring contents_wide; std::wifstream inf2(L"ucs2-be.txt"); getline( inf2, contents_wide, wchar_t(0) ); //doesn't work For example my if unicode file contains the chars A and B seperated by CRLF, the hex looks like this: FE FF 00 41 00 0D 00 0A 00 42 Based on the fact that with a multibyte file getline with '\0' reads the entire file I believed that getline( inf2, contents_wide, wchar_t(0) ) should read in the entire unicode file. However it doesn't - with the example above my wide string would contain the following two wchar_ts: FF FF (If I remove the wchar_t(0) it reads in the first line as expected (ie FE FF 00 41 00 0D 00) Why doesn't wchar_t(0) work as a delimiting wchar_t of "00 00"? Thank you

  • InterIMAP, Viewing UNREAD IMAP mail and Downloading Attachments in C#

    - by Erika
    I was wondering if anyone can help me on this cause its driving me mad trying get this working I was working with the trail of mail.dll from http://www.lesnikowski.com/mail/ which is an extremely fantastic tool which unfortunately i cannot afford being a student (even though its around 150eur, its still very expensive to me :/) and this would be a small module in my thesis and my faculty cannot afford to buy these things for students either :/ so anyway I had to go for a free tool (so please dont suggest any non open source ones - trust me i have tried them ALL).. Well, i'm trying to explore InterIMAP, and for several hours have been trying to list unread emails from my gmail account but it just doesn't seem to be working. I can connect just fine but finding the unread emails seems to be no easy task.. I have tried countless approaches but non seem to give me unread emails in my inbox (I have loads of emails in my inbox and i just want the unread ones). Would someone please assist me? I have been trying to get this working for ages now, but documentation is rather lacking and my every attempt has resulted in a fail so far. Please help!! Some code i currently have: ` IMAPConfig config = new IMAPConfig("myhost", "username", "pass", true, true, ""); config.CacheFile = ""; IMAPClient client = null; try { client = new IMAPClient(config, null, 5); } catch (IMAPException e) { Console.WriteLine(e.Message); return; } Console.WriteLine(DateTime.Now.ToString()); IMAPFolder f = client.Folders["INBOX"]; IMAPSearchResult sResult = f.Search(IMAPSearchQuery.QuickSearchNew()); // <--- Gives me no results even though i do have unread messages!

  • IE7 CSS bug aligning <img> with text in a <ul>

    - by Artem Russakovskii
    I've been banging my ahead on this IE7 bug for the last few days and it's time to resort to the mind of the crowd. I have the following HTML and CSS: http://beerpla.net/for_www/ie7_test/test.html The goal is to have a <ul>, with each <li> containing a small icon and some text. Multiline text would be aligned to itself and not wrap under the image. I've tried using float:left on the image and a bunch of other things, and finally I thought the position:absolute would work for sure but in IE7 I consistently see the text pop off to the next line and get misaligned with the image: This is what I expect it to look like: I even tried to make the div display:inline which kind of worked but then started wrapping under the image for long lines, so it was no good. zoom:1 also produced a similar effect. I'm at a loss at the moment. This code works fine in all other browsers. IE7 is a special, very special child. Any ideas? Thank you. Edit: If you have IE8, you can emulate IE7 by pressing F12 and then Alt-7.

  • Can I autogenerate/compile code on-the-fly, at runtime, based upon values (like key/value pairs) parsed out of a configuration file?

    - by Kumba
    This might be a doozy for some. I'm not sure if it's even 100% implementable, but I wanted to throw the idea out there to see if I'm really off of my rocker yet. I have a set of classes that mimics enums (see my other questions for specific details/examples). For 90% of my project, I can compile everything in at design time. But the remaining 10% is going to need to be editable w/o re-compiling the project in VS 2010. This remaining 10% will be based on a templated version of my Enums class, but will generate code at runtime, based upon data values sourced in from external configuration files. To keep this question small, see this SO question for an idea of what my Enums class looks like. The templated fields, per that question, will be the MaxEnums Int32, Names String() array, and Values array, plus each shared implementation of the Enums sub-class (which themselves, represent the Enums that I use elsewhere in my code). I'd ideally like to parse values from a simple text file (INI-style) of key/value pairs: [Section1] Enum1=enum_one Enum2=enum_two Enum3=enum_three So that the following code would be generated (and compiled) at runtime (comments/supporting code stripped to reduce question size): Friend Shared ReadOnly MaxEnums As Int32 = 3 Private Shared ReadOnly _Names As String() = New String() _ {"enum_one", "enum_two", "enum_three"} Friend Shared ReadOnly Enum1 As New Enums(_Names(0), 1) Friend Shared ReadOnly Enum2 As New Enums(_Names(1), 2) Friend Shared ReadOnly Enum3 As New Enums(_Names(2), 4) Friend Shared ReadOnly Values As Enums() = New Enums() _ {Enum1, Enum2, Enum3} I'm certain this would need to be generated in MSIL code, and I know from reading that the two components to look at are CodeDom and Reflection.Emit, but I was wondering if anyone had working examples (or pointers to working examples) versus really long articles. I'm a hands-on learner, so I have to have example code to play with. Thanks!

  • Fastest way to remove non-numeric characters from a VARCHAR in SQL Server

    - by Dan Herbert
    I'm writing an import utility that is using phone numbers as a unique key within the import. I need to check that the phone number does not already exist in my DB. The problem is that phone numbers in the DB could have things like dashes and parenthesis and possibly other things. I wrote a function to remove these things, the problem is that it is slow and with thousands of records in my DB and thousands of records to import at once, this process can be unacceptably slow. I've already made the phone number column an index. I tried using the script from this post: http://stackoverflow.com/questions/52315/t-sql-trim-nbsp-and-other-non-alphanumeric-characters But that didn't speed it up any. Is there a faster way to remove non-numeric characters? Something that can perform well when 10,000 to 100,000 records have to be compared. Whatever is done needs to perform fast. Update Given what people responded with, I think I'm going to have to clean the fields before I run the import utility. To answer the question of what I'm writing the import utility in, it is a C# app. I'm comparing BIGINT to BIGINT now, with no need to alter DB data and I'm still taking a performance hit with a very small set of data (about 2000 records). Could comparing BIGINT to BIGINT be slowing things down? I've optimized the code side of my app as much as I can (removed regexes, removed unneccessary DB calls). Although I can't isolate SQL as the source of the problem anymore, I still feel like it is.

  • How to handle correctly HTTP Digest Authentication on iPhone

    - by Fabiano Francesconi
    Hello guys. I'm trying to upload a file onto my personal server. I've written a small php page that works flawlessy so far. The little weird thing is the fact that I generate all the body of the HTTP message I'm going to send (let's say that amounts to ~4 mb) and then I send the request to my server. The server, then, asks for an HTTP challenge and my delegate connection:didReceiveAuthenticationChallenge:challenge replies to the server with the proper credentials and the data. But, what's happened? The data has been sent twice! In fact I've noticed that when I added the progressbar.. the apps sends the data (4mb), the server asks for authentication, the apps re-sends the data with the authentication (another 4mb). So, at the end, I've sent 8mb. That's wrong. I started googling and searching for a solution but I can't figure out how to fix this. The case scenarios are two (my guess): Share the realm for the whole session (a minimal HTTP request, then challenge, then data) Use the synchronized way to perform an HTTP connection (things that I do not want to do since it seems an ugly way to handle this kind of stuff to me) Thank you

  • Core Animation problem on iPhone

    - by Mac
    I'm new to iPhone development, and doing some experimentation with Core Animation. I've run into a small problem regarding the duration of the animation I'm attempting. Basically, Ive got a view with two subviews, and I'm trying to animate their opacity so that one fades in while the other fades out. Problem is, instead of a gradual fade in/out, the subviews simply switch instantly to/from full/zero opacity. I've tried to adjust the animation duration with CATransaction with no noticable effect. It's also not specific to animating opacity - animating position shows the same problem. The code I'm using (inside a method of the superview) follows: CALayer* oldLayer = ((UIView*) [[self subviews] objectAtIndex:0]).layer; CALayer* newLayer = ((UIView*) [[self subviews] objectAtIndex:1]).layer; [CATransaction begin]; [CATransaction setAnimationDuration:1.0f]; oldLayer.opacity = 0.0; newLayer.opacity = 1.0; [CATransaction commit]; Does anyone have an idea what the problem might be?

  • Delphi SAPI Text-To-Speech

    - by Andreas Rejbrand
    First of all: this is not a duplicate of http://stackoverflow.com/questions/1021490/delphi-and-sapi. I have a specific problem with the "SAPI in Delphi" subject. I have used the excellent Import Type-Library guide in Delphi 2009 to get a TSpVoice component in the component palette. This works great. With var SpVoice: TSpVoice; I can write SpVoice.Speak('This is an example.', 1); to get asynchronous audio output. First question According to the documentation, I would be able to write SpVoice.Speak('This is an example.', 0); to get synchronous audio output, but instead I get an EZeroDivide exception. Why's that? Second question But more importantly, I would like to be able to create the SpVoice object dynamically (I think this is called to "late-bound" the SpVoice object), partly because only a very small fraction of all sessions of my app will use it, and partly because I do not want to assume the existance of the SAPI server on the end-user's system. To this end, I tried procedure TForm1.FormClick(Sender: TObject); var SpVoice: Variant; begin SpVoice := CreateOleObject('SAPI.SpVoice'); SpVoice.Speak('this is a test', 0); end; which apparently does nothing at all! (Replacing the 0 with 1 gives me the EZeroDivide exception.) Disclaimer I am rather new to COM/OLE automation. I am sorry for any ignorance or stupidity shown by me in this post...

  • .NET assembly cache / ngen / jit image warm-up and cool-down behavior

    - by Mike Jiang
    Hi, I have an Input Method (IME) program built with C#.NET 2.0 DLL through C++/CLI. Since an IME is always attaching to another application, the C#.NET DLL seems not able to avoid image address rebasing. Although I have applied ngen to create a native image of that C#.NET 2.0 DLL and installed it into Global Assembly Cache, it didn't improved much, approximately 12 sec. down to 9 sec. on a slow PIII level PC. Therefore I uses a small application, which loads all the components referenced by the C#.NET DLL at the boot up time, to "warm up" the native image of that DLL. It works fine to speed up the loading time to 0.5 sec. However, it only worked for a while. About 30 min. later, it seems to "cool down" again. Is there any way to control the behavior of GAC or native image to be always "hot"? Is this exactly a image address rebasing problem? Thank you for your precious time. Sincerely, Mike

  • How to allow tap-to-focus on the camera using an overlay

    - by AJJ
    The standard 3GS iPhone camera includes tap-to-focus (I can tap to the region I want to focus on). However when I use a custom overlay using the UIImagePickerController class, the tap to focus does not seem to work. Everything else in terms of capturing images programmatically etc is working btw. Note that my overlay view is only a small rectangle (UIView) at the bottom of the screen. It does not cover the other areas of the camera. So I believe the taps should go through (unless I am missing something). I have seen other apps use an overlay and still provide a tap-to-focus functionality, so there must be a way to do this. I use all the default controls set to be hidden as: imagePicker.showsCameraControls = NO; imagePicker.toolbarHidden = YES; imagePicker.navigationBarHidden = YES; Of course changing the above does not let me tap-to-focus (it just enables the toolbars, etc). I could not find any answers on the UIImagePickerController class reference. Any help would be greatly appreciated. Thanks!

  • Is VB Really Case Insensitive?

    - by Otaku
    I'm not trying to start an argument here, but for whatever reason it's typically stated that VB is case insensitive and C languages aren't (and somehow that is a good thing). But here's my question: Where exactly is VB case insensitive? When I type... Dim ss As String Dim SS As String ...into the VS2008 IDE the second one has a warning of "Local variable 'SS' is already declared in the current block". In VBA VBE, it doesn't immediately kick an error, but rather just auto-corrects the case. Am I missing something here with this argument that VB is not case sensitive? (Also, if you know or care to answer, why would that be a bad thing?) EDIT: Why am I even asking this question? I've used VB in many of it's dialects for years now, sometimes as a hobbyist, sometimes for small business-related programs in a workgroup. As of the last 6 months I've been working on a big project, much bigger than I anticipated. Much of the sample source code out there is in C#. I don't have any burning desire to learn C#, but if there are things I'm missing out on that C# offers that VB doesn't (an opposite would be VB.NET offers XML Literals), then I'd like to know more about that feature. So in this case, it's often argued that C languages are case sensitive and that's good and VB is case insensitive and that is bad. I'd like to know A) how exactly is VB case insensitive because every single example in the code editor becomes case sensititive (meaning case gets corrected) whether I want it or not and B) is this compelling enough for me to consider moving to C# if VB.NET case is somehow limiting what I could do with code?

  • SHA1 hashing in Delphi XE

    - by Leonardo Herrera
    Hello, I'm in the process of implementing XML digital signatures. I'm starting with little steps, so right now I want to solve the problem of SHA-1 hashing. There are lots of questions about this in SO: Digitially Sign Key with Lockbox Encryption library for Delphi Convert this php digital signing to Delphi Delphi: is there a version of LockBox for Delphi-XE Delphi 2010 Cryptography libraries ...and probably more. However, I'm using Delphi XE. So far, I've tried LockBox 2 (both the Songbeamer and Sourceforge versions), Lock Box 3, DCPCrypto2 and some others (Hashes is an easy to use unit which uses Windows crypto functions) I prepared a small test rig that gives me the following: LockBox2 FAILED: 1 ('abc') Got: '9f04f41a848514162050e3d68c1a7abb441dc2b5' Expected: 'a9993e364706816aba3e25717850c26c9cd0d89d' FAILED: 2 ('abcdbcdecdefdefgefghfghighijhijkijkljklmklmnlmnomnopnopq') Got: '51d7d8769ac72c409c5b0e3f69c60adc9a039014' Expected: '84983e441c3bd26ebaae4aa1f95129e5e54670f1' LockBox3 FAILED: 1 ('abc') Got: '9f04f41a848514162050e3d68c1a7abb441dc2b5' Expected: 'a9993e364706816aba3e25717850c26c9cd0d89d' FAILED: 2 ('abcdbcdecdefdefgefghfghighijhijkijkljklmklmnlmnomnopnopq') Got: '51d7d8769ac72c409c5b0e3f69c60adc9a039014' Expected: '84983e441c3bd26ebaae4aa1f95129e5e54670f1' DCPCrypto2 FAILED: 1 ('abc') Got: '9f04f41a848514162050e3d68c1a7abb441dc2b5' Expected: 'a9993e364706816aba3e25717850c26c9cd0d89d' FAILED: 2 ('abcdbcdecdefdefgefghfghighijhijkijkljklmklmnlmnomnopnopq') Got: '51d7d8769ac72c409c5b0e3f69c60adc9a039014' Expected: '84983e441c3bd26ebaae4aa1f95129e5e54670f1' Hashes Test 1 passes Test 2 passes Have you succeeded in compile the mentioned libraries under Delphi XE and make them give the appropriate values? I'm particularly interested in DCPCrypt2 SelfTest procedure. Edit: I've added this answer with the fixed source code. Thank you all for your help, it is most appreciated.

  • Data Driven MSTest: DataRow is always null

    - by David Back
    I am having a problem using Visual Studio data driven testing. I have tried to deconstruct this to the simplest example. I am using Visual Studio 2012. I create a new unit test project. I am referencing system data. My code looks like this: namespace UnitTestProject1 { [TestClass] public class UnitTest1 { [DeploymentItem(@"OrderService.csv")] [DataSource("Microsoft.VisualStudio.TestTools.DataSource.CSV", "OrderService.csv", "OrderService#csv", DataAccessMethod.Sequential)] [TestMethod] public void TestMethod1() { try { Debug.WriteLine(TestContext.DataRow["ID"]); } catch (Exception ex) { Assert.Fail(); } } public TestContext TestContext { get; set; } } } I have a very small csv file that I have set the Build Options to to 'Content' and 'Copy Always'. I have added a .testsettings file to the solution, and set enable deployment, and added the csv file. I have tried this with and without |DataDirectory|, and with/without a full path specified (the same path that I get with Environment.CurrentDirectory). I've tried variations of "../" and "../../" just in case. Right now the csv is at the project root level, same as the .cs test code file. I have tried variations with xml as well as csv. TestContext is not null, but DataRow always is. I have not gotten this to work despite a lot of fiddling with it. I'm not sure what I'm doing wrong. Does mstest create a log anywhere that would tell me if it is failing to find the csv file, or what specific error might be causing DataRow to fail to populate? I have tried the following csv files: ID 1 2 3 4 and ID, Whatever 1,0 2,1 3,2 4,3 So far, no dice.

  • array retain question

    - by Cosizzle
    Hello, im fairly new to objective-c, most of it is clear however when it comes to memory managment I fall a little short. Currently what my application does is during a NSURLConnection when the method -(void)connectionDidFinishLoading:(NSURLConnection *)connection is called upon I enter a method to parse some data, put it into an array, and return that array. However I'm not sure if this is the best way to do so since I don't release the array from memory within the custom method (method1, see the attached code) Below is a small script to better show what im doing .h file #import <UIKit/UIKit.h> @interface memoryRetainTestViewController : UIViewController { NSArray *mainArray; } @property (nonatomic, retain) NSArray *mainArray; @end .m file #import "memoryRetainTestViewController.h" @implementation memoryRetainTestViewController @synthesize mainArray; // this would be the parsing method -(NSArray*)method1 { // ???: by not release this, is that bad. Or does it get released with mainArray NSArray *newArray = [[NSArray alloc] init]; newArray = [NSArray arrayWithObjects:@"apple",@"orange", @"grapes", "peach", nil]; return newArray; } // this method is actually // -(void)connectionDidFinishLoading:(NSURLConnection *)connection -(void)method2 { mainArray = [self method1]; } // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { mainArray = nil; // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)dealloc { [mainArray release]; [super dealloc]; } @end
