Running Exe in C++ Code.

Executing an exe at runtime

Basically i am creating a D3d App and I want the code to run this configuration (choose resolution, windowed or fullscreen, etc...)

then this config.exe will save the settings to a settings.cfg then the D3D app runs and refers to the information from the settings.cfg

is this possible? how do I do this? I want the code to run an exe file basically.

i also want to make sure that config.exe finsihes (ie exits) then the code runs the main program.

THx.

yes that can be done. How, depends on the operating system because you have to call os-specific functions. In MS-Windows you can use CreateProcess() for greatest flexibility, although there are other function slightly easier to use. *nix I think you would use one of the spawn() family of functions.

The simplest is system(), but it's not recommended for security reasons.

Here are a couple that may help you:

Running the exe and waiting using _spawnlp:

Code:

_spawnlp (_P_WAIT, "config.exe", "config.exe", Argument1 , Argument2, NULL);

Or

Running the exe and waiting using CreateProcess and WaitForSingleObject:

Code:

   PROCESS_INFORMATION ProcessInfo;

   StartupInfo.cb = sizeof(STARTUPINFO);
   if (CreateProcess(NULL, "config.exe", NULL, NULL, FALSE,0, NULL, NULL, &StartupInfo, &ProcessInfo))
   {
       WaitForSingleObject(ProcessInfo.hProcess, INFINITE);
   }
   else
   {
       // Do something else...
   }

Hope this helps.
