I am needing to run one executable from within another application.  For instance, assuming that I have a basic "Hello World" application, how would I open it from a separate application and print "Hello World" to the screen.  Basically, I am needing to know how to run command line commands within my code.  

// very simple example code
void main()
{
   // run "Hello World" application here
   // from the command line, it would look like
   // c:/hello.exe

   // do more processing...
}

The easiest way would be using "system()".

/* SYSTEM.C: This program uses
 * system to TYPE its source file.
 */

#include <process.h>

void main( void )
{
   system( "type system.c" );
}


Output

/* SYSTEM.C: This program uses
 * system to TYPE its source file.
 */
#include <process.h>
void main( void )
{
   system( "type system.c" );
}


In your case, just change it to read

   system( "hello.exe" );

You might have to provide a path, though...

system() call is the easiest to call an application. If u need more control over the way the new application is started you can use ShellExcuteEx() method. You can set different options like how the applcation should be started ( minimized, maximized etc. ) by filling the SHELLEXECUTEINFO structure and passing it to the ShellExecuteEx method.

Cheers !!!
