Can I add breakpoint on windows CreateProcess API in Visual studio like I can do in Windbg?
Yes – Go “Debug / New breakpoint / Break at function…” and paste this:
into the Function box.
That assumes a Unicode build – replace
WwithAfor ANSI builds.A bit of explanation: the
@40piece is part of the stdcall calling convention, and gives the number of bytes of parameters that the function takes. In win32, this is almost always 4 times the number of parameters. The underscore is also part of the stdcall calling convention.A related note: sometimes the name of the function as seen by the debugger is different from its real name – see this blog post for an example, and how to find the right name to use: Setting a Visual Studio breakpoint on a Win32 API function in user32.dll
