Will this even compile? Look at the last two arguments to CreateProcess.

Lose the try/catch blocks; CreateProcess doesn't throw exceptions to indicate errors and any exceptions it does throw (such as access violations) will almost certainly be your fault and should be allowed to propergate to the debugger so the problem can be fixed. I’ll gloss over the issue that the fact that try/catch can even catch access violations (and other such exceptions) is non-standard and later MS compilers have been fixed in this regard (although the old buggy behaviour can be re-enabled via a compiler switch).

Here's an example:

// Win32App.cpp : Defines the entry point for the application.
//
 
#include "stdafx.h"
 
int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR     lpCmdLine,
                     int       nCmdShow)
{
	STARTUPINFO si = {0};
	si.cb = sizeof(si);
	si.lpTitle = "Use this as the title!";
 
	PROCESS_INFORMATION pi;
 	BOOL bOK = CreateProcess(
			"C:\\Commands\\AnyKey.exe",
			NULL,
			NULL,
			NULL,
			FALSE,
			CREATE_NEW_CONSOLE,
			NULL,
			NULL,
			&si,
			&pi
			);
	if (bOK)
	{
		// If 'CreateProcess' succeeds the HANDLES in 'pi' should be closed unless you need them.
		// Failing to close them results in resource leaks!
		CloseHandle(pi.hProcess);
		CloseHandle(pi.hThread);
	}
 
	return 0;
}

There isn't a exact procedure to implementing motion detection. There are many algorithms for doing that, and searching the articles on this site anf google should bring up some results.

Good luck

i have used following four functions for motion detection part only:
1)AdjustMotionDetectPrecision()
2)SetupMotionDetection()
3)StartMotionDetection()
4)MotionAnalyzer()
using these four functions,motion detected has started.
but i dnt knw how to start recording????
i m sending u some code :

here it is::::

if(frameType > 0)
{
if(frameType == PktSysHeader)
{

memcpy(FileHeader[channelNum], DataBuf, Length);
FileHeaderLen = Length;
}

if(frameType == PktIFrames || frameType ==PktSubIFrames)
{
status = 1;
}
else
{
status = 0;
}
if(frameType == PktMotionDetection)
{
int result[4];
if(bOverlayMode)
{
hkdlg->m_VideoWin.DrawVectEx(channelNum, (char *)DataBuf);
}
else
{
hkdlg->m_bMoving[channelNum] = TRUE;
memcpy(motionData[channelNum],(char*)DataBuf,Length);
}
MotionAnalyzer(ChannelHandle[channelNum],(char*)DataBuf,15,result);
if((result[0] + result[1] + result[2] + result[3]))
{
if (channelNum ==0)
TRACE("!!!!!!!CH=%d motion detect result is %d %d %d %d\n",channelNum,result[0],\
result[1],result[2],result[3]);
//The function Trigger() do the following operation: write the video&audio data which are before the motion frame to file

if(!hkdlg->baftermotion[channelNum])
alarmFile[channelNum].Trigger(gFileHandle[channelNum]);

//when the motion frame returns,clear ualreadywriteframes[channelNum] and set it as 0 ,be ready for writing the video&audio data after motion

hkdlg->ualreadywriteframes[channelNum]=0;
hkdlg->baftermotion[channelNum]=TRUE;
}

return 0;
}
if(frameType == PktOrigImage)
{
return 0;
}

In this code should i start recording after motionanalyser() function?????????????

Is there some way how to disable playing of the system sounds (stored in registry) or any sounds for some process only?
I need to turn off sounds in webbrowser hosted in my application but I don't want to turn them off for IE globally.
Thank you!

Which would disable all sounds. Not exactly the desired result.

Sorry for my poor English .

There is a way to resolve this issue , but I didn't try it . That is to write a monitor-program hook all playsound funtion and make it(playsound funtion) disabled for the process.

You should study the hooks .

If you search the hook as the keyword in this website, you could find something.

It seems that whenever I distribute an application, it never works on my first beta testers computer, even though they are running the same O/S (Windows XP), with the latest DirectX (April 2007).

Anyone else run into this problem? What do you do to solve it?

I will try, but not likely to be helpful to you.

I make add-on aircraft and avionics gauges for MS Flight Simulator.

The "gauges" are made with an SDK supplied by MS, and compile into .dll's. However, they are not tru .dll's from what I understand. In any case, the "gauges" (multiple in one file) appear fine in my aircraft on MSFS, and he just gets a blank panel.

I made a version in which I turned off the protection code to see if perhaps the call to get verify the license key is maybe the issue as he is on XP Pro, and someone else suggested that I compile with "multi-threaded" vs. multithreaded dll as some new runtimes in an update from MS on the game has new runtimes in it. So, I will try that and see what happens too.

I am just ready to pull out my hair. But, this is my own fault for not actually going to school for this and learning the proper way, haha.

My problem is I barely understand what I'm doing sometimes. C++ is no problem, but Windows is way over my head. =)
