Run command prompt windows from Visual Basic

[Govind]

I discovered this completely all by myself.

Declaration:

Public Declare Sub system Lib "msvcrt" (ByVal command As String)

Usage:

system "COMMAND"

Where COMMAND is the command to run, like PAUSE, etc...

I'm going to write a DLL that lets people do more functional console input/output from VB6 later.

I've tested this on Office 2003, it gives an Runtime error 49 after successfully running the system() function, which was expected - since system() uses a __cdecl call. I don't know whether or not this'll work well on VB6. Someone test?

I always thought this was what Shell and ShellExecute was for ...

Im running XP SP2, and i get run-time error 49 "bad dll calling convention" (or something along those lines).

And swan is right the vb6 API for CMD is shellexecute.

Yeah its prob easier just to use shell

Shell "Command"

If you're not doing GUI stuff, why use a GUI-oriented language o:

Betting most of the things you want to do in the shell could be done more easily with C.
