[gme-users] runnning exe from GME dll

[Csaba Toth]

Hi Vijdan,

 

Again, I advise you to use CreateProcess:

http://msdn.microsoft.com/en-us/library/ms682425%28VS.85%29.aspx

 

There's a dwCreationFlags DWORD parameter for this function, and you can
specify the command window behavior with that:
http://msdn.microsoft.com/en-us/library/ms684863%28VS.85%29.aspx
 

Take a look at the DETACHED_PROCESS and the CREATE_NO_WINDOW flags,
although these refer to console processes, but I think you can suppress
the additional unwanted console window.

 

Take a look at these,

Csaba

interpreter is in C++. I solved my problem.
When I run the exe from the interpreter, a command prompt is also opened
with the exe.
I am closing this command prompt window and then interpreter goes to run
the next code line.

thanks,
Vijdan

Is your interpreter in C++ or Java? I just happened to be working with a
java interpreter this weekend and needed input from the user.
A simple dialog box was a basic 1 liner in java to get info from the
user. I haven't looked but perhaps the same can be done in c++?
