I am currently writing a program iin Visual C++ that runs in the backdrop and places a taskbar icon.  I have figured out how to place the taskbar icon and make the program restore if you click on the icon.  My problem now is that I wish to make it so that if you click on the desktop icon (like running the program again) instead of running another thread it just shows the form and transfers the focus to it.

I would really appreciate help

if you want a quick fix then you can just look for the other window.
in winmain before you create anything
HWND alreadythere = FindWindow(NULL,"your window's title");
alternately you can use
HWND alreadythere = FindWindow("mainwinclassname","");
//you said it was minimized so we restore it
return 0; //exit winmain
//if i remember correctly when you restotre it the focus should go to that window.
this method isnt the greatest because other users can have your program running on there own accounts, but im guessing that not an issue.
