To capture all the applicaitons

I usiing windows 98 and windows 2000, I wanted to capture all the applications opened in my machine.

To get all the running applications you can use the EnumWindows API (see ApiSystem.TopLevelWindows property...)

Or, in winNT or higher, you can use CreateToolhelp32Snapshot and Process32First/Process32Next to walk through all the running processes, as per the ApiSystem.Processes property...
