• Windows Forms The custom tool MSDataSetGenerator failed System Error

  Hi, Urgent help required. I have been using typed dataset (xsd), created using the dataset designer in VS 2003 (using VB.NET).

• .NET Development raising an event via reflection

  Using reflection is it possible to check if an event has a handler and more importantly raise that event. I have a string with a value of the event and the object instance which I need to fire. Thanks for the VB example. Seems a lot of folks are stuck on this issue. Here is a c# flavor of it. public event EventHandler<EventArgs> MyEventToBeFired; public void FireEvent(Guid instanceId, string handler) { // Note: this is being fired from a method with in the same class that defined the event (i.e. "this").

• Game Technologies: DirectX, XNA, XACT, etc. SetMatrixCoefficients in XNA Game Studio Express 1.0

  Ok, I'm quite puzzled, I just moved my code up from Beta 2 to XNA Game Studio Express 1.0 but can't get my last line of code fixed. Where did Cue.SetMatrixCoefficients end up I'm using it to play a mono wav in a single channel. Is there a better way of doing this now Thanks Nic Well after much research, I discovered that 3D audio simply isn't supported in the 1.0 framework. This is quite sad news. Since I couldn't find a way of fixing this problem using XACT technology in my game, I ended up making duplicates of each sound (in stereo); one that only has sound in the left channel and the other in the right channel. All that's left is simply choising the appropriate Cue to play. Luckily I didn't re ...Show All

• Smart Device Development Load Background image into ListView Control, but ListViewItems don't display...

  Hi all, I wanted to put a background image on a ListView Control, but found that when you extend on the ListView Control the OnPaint() method cannot be overridden because the CF doesn’t not call OnPaint() on the ListView. It is called lower down in the OS. Anyway, I have managed to use a class that catches Windows Messages (WM_Paint) on the ListView Control and then calls a method in my ListViewExtender class (this is through a delegate). Now I can get the ListView to display the background image perfectly. But the ListViewItems that I add to the ListViewExtender instance do not get displayed. Is this because I have used the DrawImage() method which draws the images on top of the ListView items Or is it a case that I must also re-draw the ...Show All

• Internet Explorer Development A problem with IWebBrowser2:Navigate() under IE7

  I have a problem with ie7, the method Navigate of interface IWebBrowser2 can't work as before. My application is a C++ one, there is a Browser control (BrowserObj1) which is created in the main thread, hosted in the main window.

• SQL Server Landscape Printing issue in SQL Reporting services

  I have reports, set to print on Landscape and Legal ie 14 * 8.5. However, when certain users try to print the report, it prints it in Letter, even though the report is set to print in legal /landscape. The strange part is that for most users it prints correctly in legal, only for some it is on letter. Any idea why this would happen This may be a printer driver issue, where Legal paper is unavailable. Here are a few questions to help troubleshoot this issue: Does this always occur consistently for the same users If the report is not set to landscape, does the report print correctly Can those users, for which printing fails to use Legal paper, print from another application, such as Word, using Legal ...Show All
