I came across something stating that you could access and call Windows kernel DLL functions from the command line, with rundll32.exe.
But how come this doesn't work?
Quote:C:\>rundll32 user32,MessageBox 0,"Wow","Wow",0
It runs, but it doesn't display a message box. Am I just insane, or am I doing something wrong?

Okay, I'm assuming that MessageBoxA takes the same arguments as MessageBox.

No message box...just runs, and quits. No error, no success.

A useful command, indeed, but unfortunatly it doesn't let you return anything to the command line. If you could do that... well, I think that would be pretty darn cool.

Um - "return anything to the command line". Oh, I see - MessageBox won't run unless it has someplace to put the return value, which is what button did the user click. Right?

If i do this under a DOS box in win98:
rundll32 user32,MessageBoxA Popup Test
I get a popup windows with the title 'Popup Test' saying:
MZn
Where n is a forbidden char (it shows up as a thick line, somewhat like |)
And as we all know MZ is the header for MS EXE file format.
Go figure.

That's strange. On my XP box, trying what Z!re did, exactly, nothing happens.
I suppose Microsoft doesn't want it's ickle customers to hack at the API.

There are a lot of other things that seem to work:

Opening a message box is not in any list ...Maybe it worked in W3.1 only?

Yeah. Weird, you'd think that every function (except those that are purely for the purpose of returning something) would be able to be called.
Hmm.
