• Windows Forms Additional Infos: PropertyGrid: How to catch an exception?

  I use a PropertyGrid to show a business object in my application. The business object throws exceptions if the user tries to enter an invalid string inside the PropertyGrid. The PropertyGrid shows two different behaviors in this case: If a default TypeConverter is used the PropertyGrid shows an builtin error message dialog. If a custom TypeConverter is used the PropertyGrid doesn't handle the exception. This happens only in Debug mode. How can I catch these exceptions and suppress the builtin error message dialog of the PropertyGrid The exception thrown by the PropertyGrid looks like this: System.Exception was unhandled by user code Message= "r is not a valid value for Double.&qu ...Show All

• Visual Studio 2008 (Pre-release) How to: Implement aggregates with GridView and Grouping

  I'm trying to create a sort of Outline Grid. Where you can group and the Grouped item contains the sum. Eventually I need to include a Min and Max for dates. +/-Group1 20 50 item1 10 40 item2 10 10 I was thinking that extending the CollectionView and CollectionViewGroup might work, but before traveling down that long road I figure I'd see if anyone has had experience with this sort of thing. The goal is so that when you're creating the GroupItem style, you'll be able to reference ItemSum, just like ItemCount that currently exists. There is still an issue as to what column you need to sum, which I haven't really thought out yet. The other issue is that I'll need the group data to refresh when the item data changes. ...Show All

• Visual C++ typecasting a pointer?

  Hello everyone, I'm using VC++ along with a 3rd party library to capture and display images from a CCD video camera. I'd like to aquire the grayscale values in order to do some image processing but I'm a little uncertain as to the correct way. The images are either 8, 10 or 16-bit grayscale. The images are loaded into a buffer as follows: uInt8* imageBuffer; imageBuffer = (uInt8*)malloc(ImageWidth * ImageHeight * BytesPerPixel * (sizeof(uInt8)); At this point I call the grab function from the 3rd party library, passing the above pointer as one of the arguments. My question is how do I access the values that are stored in the buffer Let's assume I know a priori that the image is 10 bit...do I typecast the pointer as 16-bit and get the ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 3D VERY slow on the XBOX

  Im having a hard problem getting good FPS rates on the XBOX, everything turns around and gets alot slower. Does anyone have a solution, or reason for this That profile definately looks like garbage collection is the problem. It is collecting once per second, and taking 38 milliseconds to do so: in a game running at 60 frames per second this will cause a hitch of two whole frames. There are basically two ways of improving GC performance: either reduce the amount of garbage you create so the GC will happen less often (it will still hitch when it does happen, but if you can get this rare enough, that might not be a problem), or reduce the amount of live objects so the GC will run faster when it does ...Show All

  Hello, I installed VS 2005. Once I launched VS, it asked what IDE I would like to run with, I chose VS 2005 C#, NOT realizing that Developer Team Edtion was a selection. How can I make this VS 200 Developer Team Edtion my default IDE Regards, Spandon From within Visual Studio, access the Tools menu.  Select Import and Export Setttings... and then Reset all settings .  It is your call as to whether you'd like to back up the current settings; I usually don't.  Then select your environment (e.g., General Development Settings) and let'er rip.
