[Nasm-users] How to call MessageBoxA from Nasm program?

[<oh...@co...>]

Hi,

I'm trying to add a call to MessageBoxA in a Nasm app.  I know how to setup the parameters for the call, but I can't get Nasm to assemble successfully.

I have added an "extern MessageBoxA" and "import MessageBoxA user32.dll" (this is on Windows), but when I do that, I get an error from parser saying that an instruction is expected.

If I comment out the "import" line, I get a linker error.

Am I not suppose to use both the "extern" and "import" lines, before the .Code line?

Thanks,
Jim
