Hi all:
I remember I saw this a long ago, but cannot find it.
I want that whenever I open an specific window, if an instance of it
is already open, just to give it focus and show it up front.
And the same also for my app, i.e. just have one instance running.
TIA

Pedro,

To stop multiple instances of your App running you need to use a mutex
- there ws a reason post on this but I cnnot remeber he title of it.

For the windows in your own - assuming you have a Shellwindow as the
basis do the following:

1. In the Open method of the Shell call the GetallChildren method .
This will rturn an array of child windows.
2. Loop through this array checking for the window you want to see if
it is en
3. if yes, use SetFocus method
4. If not open it

The child windows then call the open method of the ShellWindow rather
than handling it themselves.

Hope this helps.

Kevin
