• Visual Studio Express Editions Save As animated gif impossible?

  I am working on an image editing application and am on the final step, which is the user saves the 3 images they have edited as one animated gif. I have done a lot of web searches trying to find some code that will accomplish this, but have come up empty. Is it possible If so, how is it done   Hey Widget.... We could working on this together. The first thing to know about C is that their syntax is backwards.

• Windows Forms Can't get DrawItem event any more, in some special case

  This interesting thing was found by use of DebugView to monitor the all events. Suppose that there are 2 controls, one is propertyGrid, one is myListBox, which is a subclass of ListBox. myListBox uses OwnerDrawFixed mode, so it has to draw all items manually. However, in some mysterious case, I found that when I repeatedly opened and closed the propertyGrid, myListBox may never raise any DrawItem event. I output all events to DebugView, then found that WM_PAINT was there, but didn't WM_DRAWITEM. Also it can't restore from this bad status no matter what I did (move, refresh, resize, maximize, minimize...), until I recreate another myListBox. I think WM_DRAWITEM is nowhere to be manually emitted, since it's managed by control. ...Show All

• Visual Basic Using the built in SQL Database

  I'm using the built in SQL Database in VS.NET. I am currently writing a paper in VB and I have a quick question about the SQL Database. I have made a Player_ID field and I was wanting to make it the primary key, but what I want to do is whenever a new player is added, I want it to automatically increment the Player_ID like you can in Access. How would I do this I have tried the UniqueIdentifier type but it doesn't work. What am I doing wrong you need to set the "Identity" field to yes and you don't need to use a uniqueIdentifier field type, you can use an integer. Also be sure that the Identity Increment is set to 1. ...Show All

• Windows Forms fillbytoolstrip - what is this?

  VB 2005 I have a form with a DataGridView filled by a TableAdapter. Somewhere along the way a control was added to my form in the top left corner that is defined as a System.Windows.Forms.ToolStripButton called FillByToolStrip. I did not name this control and I didn't ask to have it added to my form, but I'm afraid to delete it in case it is needed. I have tried to hide it, but when I do the text (in this case, it defaulted to FillBy) is not shown but there is a gray area where the control should be. The form background is a light blue color and I set the background color for this control to that same value, but it still shows up as a gray area on the otherwise blue background. The word 'fillbytoolstrip' returns NO hits on any Microsof ...Show All

• Visual C++ Legacy MFC app using HWND_TOPMOST

  Hi All... We have a browser-based application that uses an active-X control to spawn off another process. This spawned process is written using MFC. It performs a call to SetWindowPos with HWND_TOPMOST specified - this is so the application will force itself to the top of the Z-Order. And (until now) it works fine... We've found however, that when that that active-X control lives in IE7, the app spawned does not force itself to the top of the Z-order. It gets above all other apps except for the IE7 from which it was spawned. Any ideas as to why IE7 refuses to allow the app to get above its Z-order Hi Rico, Thanks for your reply. I must say that these forums here at Microsoft are in my opinion the best ...Show All

Is this true If it is, is it possible to export cameras and lights to a different format that can be used with directX, or do we have to insert all cameras and lights in C++ Thanks. ...Show All

• SQL Server mail task

  how to attach a xls file that will be created at run time using mail task. I get a file does not exist error if the file is not there. If the file is not there, then obviously you would expect the task to fail. If your are just having issues because at the start of execution the file is not there, but it will exist by the time the mail task actually runs, use the DelayValidation property. This will stop the mail task validating at the beginning of package execution, it will only validate immediately prior to the task execution, by which time you should have written the file. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA Framework / Effects

  The effect system has a simplified programming model compared with MDX Basically what that means is that rather than having a single class with a few dozen methods it's split out into a type safe object model hierarchy where each class has just a few methods and collections of child objects. This is the case for all of XNA Framework, and by doing this the API becomes more discoverable and more similar to the structure of the classes in the core .Net framework. Here are two of the main classes they showed from the Effect system: public class Effect { public GraphicsDevice GraphicsDevice { get ; } public EffectPool EffectPool { get ; } public EffectTechnique CurrentTechnique { get ; } public EffectFunctionCollection Fun ...Show All

• Software Development for Windows Vista Appverifier and VB6

  Hello, we are currenty in the certification process for the "Certified for Windows Vista" Logo Program. One Test Case is: "Verify application does not break into debugger with the specified AppVerifier checks". We discovered that the Debugger (WinDbg 6.6.0007.5) stopps when a VB6 application uses the "On Error Resume Next" Exceptionhandling (I know that this is not good coding, but it is valid). At runtime, the exception is handled by the VB6 Runtime and everything is OK. When using the debugger, it reports an error at the exception handling of the application. Sample: Private Sub ExceptionTest() Dim myRecordset As ADODB.Recordset On Error Resume Next myRecordset.Close ' Debugger breaks here! ...Show All

• .NET Development Delegate Keep alive

  Hi, I have a problem with using delegates with pinvoke. I have a delegate for a reporting function that is required for the lifetime of the application. The callback works for the first time and after that if the dll reports any error I get an access violation exception. This is because the delegates gets collected. Any suggestions on how to avoid this error Thanks! Language I am using is C#. It is a windows forms application. I actually declare the delegate in the main method and I have GC.KeepAlive at the end, so it is something like ReportingFunction reportFn = new ReportingFunction(SomeClass.Report); //The application performs many operations....

• Visual C++ VC++ IDE file output settings.

  In the C# and VB IDE you can set any file in your solution whether it be a text file or whatever to be copied to the output directory (either debug or release). In the VC++ IDE you cannot. How would I do this in the VC++ IDE IDE: Visual Studio 2005 Professional I guess the IDE hates me. I've tried many ways to copy my ini files to the debug/release directory but none of the macros I use are working. Could someone provide me with a custom build step setup where it will copy an ini file (or any file) from the main project directory to the debug/release directories. Thanks if you do. ...Show All
