RUNNING PROGRAM DETECTION > I need to write a program that will look for certain active programs (for > example Launcher.exe) while they are in memory. There are 2 ways to do this. Using FindWindow or EnumWindowsworks on all 32bit windows versions, but is only suitable if the applicaiton has a main window and the title doesn't change. The better method is Enumerating processes, this is different between Win9x and WinNT. I have examples of both methods at: www.viewpointsa.com\faq\ Look for FAQ 3 & FAQ 4. Regards, Anthony Richardson anthony@viewpointsa.com ************************************************************* Andrew, take a look at the delphi-programming files section (egroups.com) there is a windowwalk.zip file which lists all running windows on the system. This should get you started. Other than that take a look at the following API's FindWindow GetWindow GetTopWindow GetParentWindow EnumWindows EnumChildwindows Si Carter Orcka Development (http://www.orcka.com) ~ Email: simon.carter@orcka.com ************************************************************** > Finally, you will need to call > CreateToolhelp32Snapshot to get a list of all of the active threads and > check whether any of them match your window's thread.

It is important to note that ToolHelp32 only works under Win9x/ME, for WinNT/2K you need to use PSAPI.DLL. An example Delphi Object wrapper around both is availble on my site (www.viewpointsa.com\faq\) look for FAQ 4 "How do I enumerate all processes running on Windows?". This will use the correct method automatically making your application WinOS neutral. Regards, Anthony Richardson anthony@viewpointsa.com ******************************************************************* Although you can find many examples by searching for EnumWindows and Delphi in Google, You will probably have to do something like the following: Each time that windows calls back your EnumWindowsProc function, it will give you the handle of a window. If that window is a top level window, with no owner, etc. then you will need to get the thread that owns that window with GetWindowThreadProcessId. Finally, you will need to call CreateToolhelp32Snapshot to get a list of all of the active threads and check whether any of them match your window's thread. If so, you can check the member variables of the structure returned in Process32Next for the executable name. This is the only way I know how to get the exe name of a window. Does anyone else know a better way?
