I am having a C++ Builder 6 program that calls diffent exe's from the main form. If i call these exe's on any button press, I get a OS Access Violation.
I am using the following line to call the exe.
spawnl(P_NOWAIT,"Sample.exe",NULL);

I DO NOT want to use system command since it opens up a command window.

Strangely the spawnl command works when i use menu items on the same form and call them on menu press and DOES NOT WORK when  using any events on the form.

Please Help

Use the ShellExecute Windows API function...it always works.
