Equivalent of GDB's "call" in Ollydbg (or other Windows debugger)

debugging, ollydbg, windbg, windows

Solution

I don't know how to do it using OllyDbg but since you mention other Windows Debuggers you can use the `.call` command in WinDbg.

0:001> .call ABC!DoSomething(1,2)
Thread is set up for call, 'g' will execute.
WARNING: This can have serious side-effects,
including deadlocks and corruption of the debuggee.
0:001> r

ABC!DoSomething:

0:001> dd esp

The best explanation for it is from The Old New Thing.

Problem

In GDB, I can call a function that is part of the executable I am debugging by issuing a command like `call foo("123")`. How do I do the same in OllyDbg (or possibly some other primarily Windows debugger)?
