New developer question

Hi everyone,

If I running an application, I want to know whether another application is running or not, how can I do this in the application programming.

thanks help

Call "FindWindow" with the window class name.

The window class name can be found by using CESpy or something similar.

I have use the FindWindow, But it retrieve the current application program.
The question is that I want to retrieve another application which some name "xxx.exe"
How can I achieve this??

vcaretr, I presume you know either the class name or window name of the main window of the app you are trying to find out if it is running.

static CWnd* PASCAL FindWindow(
LPCTSTR lpszClassName,
LPCTSTR lpszWindowName );

How is this app related to the app you are writing?

Easiest way:
- Find the window class of the executable by using remote Spy++ from EVC++ tools
- search for that with findwindow

Harder way: get a list of processes running
- create a snapshot of the 32 processes running with CreateToolhelp32Snapshot
- Walk through the snapshot looking at the szExeFile in each PROCESSENTRY32 returned by calling Process32First then Process32Next
- Close the snapshot!

Option 1 is the way to go if you can do it.
