• Game Technologies: DirectX, XNA, XACT, etc. Delay garbage collection?

  In managed code, I understand that GC is performed at times which are hard (if not impossible) to predict, which can somtimes damage framerate performance. Is it possible to postpone GC until a time where the programmer would see fit For example, when the camera is not moving. No, garbage collection fires when the GC logic decides that it needs more memory. However it will only happen at a point when new memory is allocated so if you told new any objects (value types don't count) then you will never get a GC a GC level 0 will not be noticable in your game so you should work to only have those happen. This means either having very long lifetimes and very short lifetimes. Search Tom Millers blog and R ...Show All

• Visual Studio How do you disable the MDA tool!

  Hi all, I've been facing the same issue as everybody regarding the MDA debuging message. I just read the following post: This is a bug in the MDA. The timmer keeps running even if the debugger is stopped. The fix would have been to only run the timer when the application is running but that fix didn't make it into the product. This makes the MDA very noisy. This should have ment that the MDA should have been disabled by default in the VS exception dialog but that change also didn't make it into V2.0. The whole issue was discovered too late. So the work around is to simply open up the VS exception dialog and disable that MDA. I cannot disable the MDA in my VSTS using Debug > Exceptions, the flag is ready only. I read another pos ...Show All

• Visual C++ assigning derived class from base class declaration

  Hello; For the following code, know that Poodle is a derived class of Dog, and that aPoodle is an instanciation of Poodle. In the code below, I would expect dogObject to become a pointer to aPoodle, but it doesn't seem to work for me. Instead, dogObject seems to only maintain the attributes of dog.

• Windows Forms DataGridView row height

  Hi, I need to calculate the height of a datagridview row before it is created, but I can't figure out how to do it. I am trying to fill a datagridview with only as many rows as will fit. In order to do that I need to know how tall the rows are going to be. I guess I could create the first row and then measure it, but I figured there had to be a more elegant way to do it. Thanks in advance.

• SQL Server Built-in data types in SQL Express: best practices?

  Greetings, I think these should be rather simple questions, yet I spent a number of hours last night digging through the forums here and msdn and couldn't find any satisfactory answers. Basically, there tend to be types of information that are commonly saved in most databases, like names, addresses, phone numbers, email addresses, etc...and there are a variety of built in data types in SQL Server. What are the best built in datatypes for some of the common entries in a sql database. Also, there are a number of character based types and I am curious why one would be more useful in certain situations than another. Why is there char( ), nchar( ), varchar( ), nvarchar( ) and text datatypes Why so many Also, what is the "text" ...Show All

• Visual C# "Very" Dynamic Casting

  I'd like to do some "in-line" weird dynamic casting, kinda like this: PropertyInfo AttInfo; AttInfo = ( PropertyInfo )aMember; //aMember is referencing a PropertyInfo. string myDate = "2006-05-04" ; //CMSObject is an instance that has the property referenced by "AttInfo". AttInfo.SetValue(CMSObject, (AttInfo.PropertyType) myDate, null ); In the above code, I've bolded my fantasy-like casting capability. Assuming that the type of the property (referenced by AttInfo) is a DateTime, the attempt to set the property on CMSObject will also automatically try to convert the myDate string into the type of the property (which we'll pretend is a DateTime in this example). Is there a syntax for ...Show All
