Thread: New Console Window

You could also go "low-tech" with system().

Man that CreateProcess deal is totally raping me...

so many offshoots...and of course MSDN always has a nice way of explaining everything ;P

but ill get it...it will just take me a while and quite a few tries...

but thanks!

If this is any help, here's some code to start and stop a process.

Code:

#include <windows.h>
#include <stdio.h>

HANDLE StartProcess(char *sExe)
{
	BOOLEAN bResult = FALSE;
	STARTUPINFO SI;
	PROCESS_INFORMATION pi;

	SI.cb = sizeof(STARTUPINFO); 
	SI.lpReserved = NULL;
	SI.lpDesktop=NULL;
	SI.lpTitle = (char*) sExe;
	SI.dwX = 400;
	SI.dwY = 200;
	SI.cbReserved2=0;
	SI.lpReserved2=NULL;
	SI.dwFlags= STARTF_USEPOSITION;
	SI.wShowWindow=SW_SHOWNORMAL;   
	SI.hStdOutput=GetStdHandle(STD_OUTPUT_HANDLE);
	SI.hStdInput=GetStdHandle(STD_INPUT_HANDLE);
	SI.hStdError=GetStdHandle(STD_ERROR_HANDLE);

	bResult = CreateProcess ((LPTSTR)sExe,	        
						(LPTSTR)NULL,				
						(LPSECURITY_ATTRIBUTES)NULL,
						(LPSECURITY_ATTRIBUTES)NULL,
						(BOOL) TRUE,				
						(DWORD) CREATE_NEW_CONSOLE, 
                        GetEnvironmentStrings(),	
						NULL,						
						(LPSTARTUPINFO)&SI,			
						(LPPROCESS_INFORMATION)&pi	
						);
	return pi.hProcess;
}

int main()
{
	HANDLE h;

	printf("Starting process\n");
	Sleep(1000);

	if( h = StartProcess("test2.exe") )
	{
		printf("Process started\n");
		Sleep(5000);
		TerminateProcess(h, 0);
		printf("process terminated\n");
	}
	else
		printf("Failed to start process\n");

	return 0;
}

Oh yea that helps alot

cept one thing that doesnt compute...is the

Code:

CreateProcess ((LPTSTR)sExe

what is sExe?

I guess I can run about looking for it...

Thanks for all of the other stuff though, it really helps having a template to compare to.

>what is sExe?
just the string of the filename past to the StartProcess() function. StartProcess(char *sExe)

You could just pass the filename directly the CreateProcess() function instead.

Code:

CreateProcess ((LPTSTR) "Test2.exe",

Learning how to use CreateProcess() is good and all, but if you're simply going to use file I/O to communicate between the processes, system() is alot easier to call/use.

Yea im sure system is alot easier...but Im not really programming the ecosystem just to do it...its so I can learn as much as possible. So CreateProcess is probably the way to go.

Thanks for all the help~

While you're learning, there's a "mid-tech" solution as well.
