c++ - argv corrupted by long directory names

I'm passing arguments to the following Win32 console application:
     C:\Documents and Settings\James\My Documents\My
Stuff\Development\Test.exe

When I use the debugger to test this, instead of *argv[0] containing the
above file spec it contains the characters leading up to the first space.
So,
*argv[0] == "C:\Documents"
*argv[1] == "and"
*argv[2] == "Settings\James\My Documents\My"
....

Anyone know a solution to this ?

*argv[0] always contains the name and path of the executable.
User supplied arguments start at *argv[1].

Anyways I tried the same thing and for me it seems to work just fine:

#include <stdio.h>

int  main ( int  argc, char  **argv )
{
   for ( int  i = 0 ; i < argc ; i++ )
      printf ( "'%s'\n", *( argv + i ) );

   return (  0 );
}


C:\Documents and Settings\JAK\Local Settings\Temp>test0149 test
'C:\Documents and Settings\JAK\Local Settings\Temp\Test0149.exe'
'test'

C:\Documents and Settings\JAK\Local Settings\Temp>test0149 test

'test'

C:\Documents and Settings\JAK\Local Settings\Temp>cd\

C:\>"C:\Documents and Settings\JAK\Local Settings\Temp\Test0149.exe"

Are you sure you are targetting Win32?

I actually made a slight mistake in my original description of the problem.
I'm passing 3 arguments to the IDDE Project->Arguments facility.
Writing all arguments received to the screen (enclosed in <>), I get:

argc is 9
arg 0 <C:\Documents and Settings\James\My Documents\My
Stuff\Development\Work Areas\MODFLNM\modflnm.EXE>
arg 1 <and>
arg 2 <Settings\James\My>
arg 3 <Documents\My>
arg 4 <Stuff\Development\Work>
arg 5 <Areas\MODFLNM\modflnm.EXE>
arg 6 <music>
arg 7 <wav>
arg 8 <mp3>


Running the same program from the command prompt, the output is:

argc is 4
arg 0 <C:\Documents and Settings\James\My Documents\My
Stuff\Development\Work Areas\MODFLNM\modflnm.EXE>
arg 1 <music>
arg 2 <wav>
arg 3 <mp3>

By the way, I'm running SCWMN32.EXE.

Thanks for the clarification. The IDDE doesn't handle spaces in path names
in general. I hope to get this fixed in the future, but for now we're stuck
with that. Sorry.

Thanks.
I'm still at the very early stages of programming in this environment, so
API calls are still a little advanced for me.
I haven't started on c++ yet.
Thats's why I'm using the Win32 console.
