Using CommandLine

[shadow]

Hi again!  :P
Does does anyone know any good methods for extracting command line parameters from the path returned by GetCommandLine?  I've been comparing the entire string with the same string+the parameter, but I know there is a more efficient way.  Is there someway I can just read whats after the delimiter?  ::)

thanks!  :wink

Hi Shadow,

Here is an example for you, check the attachment to view the command line parser function ParseCmdLine , you need to allocate 512 bytes as buffer for the function.

i just happen to have one that could handle "long arguments" too.  it may not be as compact or optimized as vortex's but with the tests ive run, i catches even the wierdest lines too.  :)  sorry about the lack of comments but you will get the idea.

The MASM32 Library has some CL tools too!!
