Declare Function CreateToolhelp32Snapshot Lib "kernel32.dll" (ByVal dwFlags As Long, ByVal th32ProcessID As Long) As Long

Description

CreateToolhelp32Snapshot creates a snapshot of what is running on the computer the moment the function is called. Depending on the flags specified, this snapshot can include running processes and/or threads, among other things. With this snapshot, you can then examine what things were running when the snapshot was made. After your program no longer needs the snapshot, destroy it using CloseHandle. CreateToolhelp32Snapshot Takes a snapshot of the processes and heaps, modules, and threads used by the processes. System.Diagnostics.Process.GetProcessesSystem.Diagnostics.Process.ModulesSystem.Diagnostics.Process.Threads

Return Value

If successful, the function returns a handle to the snapshot that was made. If an error occured, the functions returns -1 (use GetLastError to get the error code).

Parameters

dwFlags A combination of the following flags specifying which information to include in the snapshot: TH32CS_INHERIT Make the returned snapshot handle inheritable. TH32CS_SNAPALL Include everything (heap list of a process, modules, processes, and threads) in the snapshot. TH32CS_SNAPHEAPLIST Include the heap list of the process specified by th32ProcessID in the snapshot. TH32CS_SNAPMODULE Include the module list of the process specified by th32ProcessID in the snapshot. TH32CS_SNAPPROCESS Include the process list in the snapshot. TH32CS_SNAPTHREAD Include the thread list in the snapshot. th32ProcessID The identifier of the process for when TH32CS_SNAPHEAPLIST or TH32CS_SNAPMODULE is specified in dwFlags. A value of 0 indicates the current process. If neither of those two flags are specified, this parameter is ignored.
