• Visual C++ _tmkDir

  Hi, If I have two seperate threads creating the same directory using _tmkdir, is synchronization required If internally _tmkdir works by checking the existence of a dir and then creating it if it does not exist, then I was wondering about the condition where two invocations of the _tmkdir might conclude that the dir does not exist and might try to create the directory. Can anyone tell me what would happen. Thanks a lot, KarthikR ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Elapsed Timer Inconsistant?

  In working on my game I developed a throttler that runs off of elapsed time to handle problems I was having using keyboard input. Basically update and draw were appearing to detect the keyboard keys multiple times for each keypress (I am using the Input code from the spacewars demo). The problem is about every 4-5 seconds or so the elapsed time apears about double the float value it does every other time. Tracing out the data it seems most changes to the elapsed time run around 0.0125 seconds, with the occasional 0.025 second spikes. I know we are talking fractions of a second here, but the reusult is every once and a while I still get multiple key presses detected, and upping the threshold doesn't help until I move up to 0.5 second ...Show All

• SQL Server System.IO.FileLoadException: LoadFrom(), LoadFile(), Load(byte[]) and LoadModule() have been disabled by the host.

Catalog your assembly in the database and call Assembly.Load("asm_name"), and it should work. Niels ...Show All

• Visual C++ vector::resize causes floating point exception

  Hello, I'm hoping for a reality check here. The following program generates a floating point exception in the vector::resize call. I compiled it under VC 2005 using the command line in the comment below. I've disassembled the executable and found that vector::resize creates a default Point object which is then copied to the new empty elements at the end of the vector. But note that the Point constructor doesn't initialize the x and y members. This means the bits are garbage, and vector::resize will copy the garbage to the new elements. This is no biggie because I don't use the uninitialized elements. However, the problem is that the compiler uses the floating point processor to copy the doubles. Whe ...Show All

• Visual C# How can I change the volume using C#?

  How can I change the volume using C# Thanks, I want to use a trackbar or buttons (up and down) using QuartzTypeLib(quartz.dll) IMediaPosition, but when ever I try to change the vol., Value is out of range. Is there another way to change the volume other than using the Master Volume You can easily implement your own by inheriting from the TrackBar class and painting it yourself or completely building your own from scratch. Take a look at these two Code Project article on some examples on how it can be done. Also, rather than continuing to ask questions in this thread I would suggest asking new ones in separate threads so that they are visible to others and where you’d like get a faster response because despite activity ...Show All
