Execute an exe within a c++ app

[davidmelvin]

I would like to execute an executable file (exe) that is located in the same directory as my application. I don't want the cmd.exe window to pop up when it happens. So I don't want to use system(), or do I? It would be fine to use system() if the window would quickly disappear when it executed.

I am using c++ Builder. This operation will happen without user interface. The user will click a button that will start a sequence of operations including executing the exe.

Thank you for your help.

Call CreateProcess to execute your exe !
...
SI : TStartupInfo;
PI : TProcessInformation;

FillChar(SI, SizeOf(SI), 0);
SI.cb := SizeOf(SI);
SI.dwFlags := STARTF_USESHOWWINDOW;
SI.wShowWindow := SW_HIDE ;

CreateProcess(
Nil ,
PChar('ExeFile') ,
Nil , Nil , True , 0 , Nil , Nil , SI , PI ) ;
.....

Hope this Delphi code snipper will help you!

I use:

if(WinExec(&quot;complete path to desiredProgram.exe&quot;, SW_SHOWNORMAL) < 32) {
ShowMessage(&quot;I can't run: desiredProgram.exe&quot;
// Take whatever other failure action here
}
else {
// Take whatever success action here
}

if it's a console/dos app you want to execute just use:


#include <process.h>
...
spawnl(P_DETACH, &quot;PROGNAME&quot;, &quot;PROGNAME&quot;, NULL);

As far as I remember there also exists one function as ShellExecute. John Fill
