.data
myName db 255 dup (0)
.code
start:
Invoke GetCommandLine
mov myName, eax
end start
why does this not work? i cannot mov eax in to MyName buffer..
Won't work, you need a DWORD sized memory operand for EAX. What you "should" be returning is a POINTER to the address of the string buffer.
Now in the case of "GetCommandLine" it actually returns a POINTER to a buffer that you do NOT allocate, the system does that. What you can do is copy it to a buffer of your own once you know how long the command line is and allocate a buffer of that size. In this context you use dynamic memory like GlobalAlloc or one of the other allocation strategies.
For testing.

.data?
myName dd ?
FirstArg dd ?
.code
start: invoke GetCommandLine
mov myName, eax
MsgBox 0, myName, "The raw commandline:", MB_OK
sub esp, 400 ; create a buffer
mov FirstArg, esp ; store address of buffer
invoke GetCL, 1, esp ; Masm32 library function
MsgBox 0, FirstArg, "Arg1:", MB_OK
add esp, 400
exit
end start
