Executing a C Executable from Another C program

finnpark · 21-03-2005 11:43AM #1

Hello All,

I am looking for help on executing a C executable from within another C program.

Basically I want to execute an executable on the sly without the user really knowing that another C program is actually executing.

Is this possible?

Thanks for any help.

No doubt some call like exec() (I don't know any C) will do the job for you?

You can using the CreateProcess function I showed you in your other post.

add these 2 lines
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_HIDE;

For testing swap SW_HIDE with SW_NORMAL

DWORD ExitCode;
STARTUPINFO si;
PROCESS_INFORMATION pi;


memset(&si, 0, sizeof(si));
memset(&pi, 0, sizeof(pi));
si.cb = sizeof(si);
si.dwFlags      =   STARTF_USESHOWWINDOW;
si.wShowWindow  =   SW_HIDE;

// Create the process. 
if(!CreateProcess(NULL, "C:\\Program Files\\Internet Explorer\\iexplore.exe www.boards.ie",NULL,NULL,FALSE,CREATE_NO_WINDOW,NULL,NULL,&si,&pi))
   AfxMessageBox("CreateProcess failed.");

// Close process. 
GetExitCodeProcess(pi.hProcess, &ExitCode);
TerminateProcess(pi.hProcess, ExitCode);

exec or system. Exec's probably handier if you want to provide arguments.

Thanks All,

Your help appreciated. All solutions suggested here work. In the end I am using system("name.exe"); as it is the handiest.

Thanks again and yes I am am being very naughty.
