How to start an application in the background using "oscmd" on windows

[Farshid]

Is there any way to launch a windows application using oscmd without suspending xmath?

From a "cmd" window one can use the start command:

> start notepad

Which starts the application without suspending the "cmd" window.

From xmath command line, one may use:

> oscmd("start notepad")

This starts the application. However, the user cannot interact with xmath as long as the application is running.

Thanks

Hi Farshid,

There is a command in the Shell API of Windows that runs an executable:

#include <utility.h>
#include <ansi_c.h>
#include <shellapi.h>
#include <windows.h>

int main (int argc, char *argv[])
{
    int res;
   
    if (InitCVIRTE (0, argv, 0) == 0)
        return -1;    /* out of memory */
    HINSTANCE stuff;
   
    stuff = ShellExecute(NULL, "open", "notepad.exe", NULL,NULL, SW_SHOW);
   
   
    printf("%i",stuff);
   
    return 0;
}

You can build a similar program into an executable and since the Parent executable will finish executing, control will return to XMath even while notepad is still open.
