Also, I have read in Game Development books to use QueryPerformanceCounter() and GetTickCount() because they're more accurate.

don't put your binary direclty into the start menu. let it in a folder (in program files for example), and just add in the start menu a shortcut (.lnk) to your .exe.

What is the best way to arrange a ListCtrl to be re-drawn when the Window has been Minimised.
At present the CListCtrl is not on the dialog following a restore from a Minimised.
|
|
|
|
|
Catch WM_SHOWWINDOW, and force a redraw of the control with RedrawWindow() when the window is restored.
~RaGE();

I want to generate a message handler say COM_HANDLE which gets called, as soon as any character is received on COM1 port, from an external hardware. How can I make such an handler in VC++ ??? It will be great if I can get a code sample for doing it.

Hi all out there... i have a little problem with using DirectShow..
i got errors like the those shown below.. is there any1 who know how to debug it?
KNN error LNK2001: unresolved external symbol _CLSID_AudioCompressorCategory
KNN error LNK2001: unresolved external symbol _CLSID_FileWriter
KNN error LNK2001: unresolved external symbol _CLSID_FilterGraph
KNN error LNK2001: unresolved external symbol _CLSID_SystemDeviceEnum
KNN error LNK2001: unresolved external symbol _IID_IAMStreamConfig
KNN error LNK2001: unresolved external symbol _IID_IBaseFilter
KNN error LNK2001: unresolved external symbol _IID_ICreateDevEnum
KNN error LNK2001: unresolved external symbol _IID_IFileSinkFilter
KNN error LNK2001: unresolved external symbol _IID_IGraphBuilder
KNN error LNK2001: unresolved external symbol _IID_IMediaControl
KNN error LNK2001: unresolved external symbol _IID_IMediaEvent
The document from DirectShow says that Strmiids.lib are used to exports class identifiers (CLSIDs) and interface identifiers (IIDs). All DirectShow applications require this library. So i am wondering whether did i link this lib to my project. Is including <dshow.h> just enough? But y am i still having the same errors???

Hello to everybody,
I tried to use the implementation of George Anescu[^] for encoding some text but I'm not sure I encrpyt correctly the data..... datas are taken from a buffer and are in plaintext, I allocate a buffer using
<br />
char *buffer_in=(char*)calloc(strlen(mainbuffer)+1,sizeof(char));<br />
char *buffer_out=(char*)calloc(strlen(mainbuffer)+1,sizeof(char));<br />
and the encrpyt it using
<br />
oRijndael.MakeKey(key, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0",16,16);<br />
oRijndael.Encrypt(buffer_in, *buffer_out, lenght,2);
where lenght is strlen(mainbuffer)+1;
when I've executed oRijndael.Encrypt(....) I've got into buffer_out the data encrypted, but using strlen I get a lenght < of buffer_in, should I use _msize? the problem is that using oRijndael.Decrypt I've a lenght that's not the one of buffer_in,so Decrypt fails...
Hope someone has used this implementation of AES and can help me, thanks

I have a video processing application that takes input for a web camera, do something on each frame, and immediately display the result. The application runs quite well in the beginning, with frame rate reaching up to 20fps. The problem is, it seems that the application slows down after it has run for a long time (something in the range of 15 hours or so). At this time, the frame rate is only 4 fps or so. I know it is impossible for someone to pinpoint what the problem exactly is, what I want to know is what are the possible causes for this. I have been scratching my head for the past few hours and the solution still eludes me.
Some information about my application that may be useful:
1. My app is a directshow filter
2. There is no harddisk access involved, as my app only process input frames (obtained from a webcam) and immediately display them on screen
3. I didn't detect any memory leaks, when my app's performance dropped to 4fps, it is only consuming around 10% of the available memory
4. After the performance dropped to 4fps, sometimes the fps count can increase again up to ~8fps, but it never reaches the original fps count (20 fps)
5. I have tested the app on several PCs with different configurations, and all of them exhibit the same behaviour
Thanks!

3. I didn't detect any memory leaks, when my app's performance dropped to 4fps, it is only consuming around 10% of the available memory.
Two ideas come to my mind:- Could it be a memory fragmentation issue? Do you happen to heavily allocate and free memory for each frame? If so, maybe you can try redesigning your stuff so that memory is reused instead, or something along that direction.
- Maybe you're running out of GDI resources?
