if (c:\\newguy\\cpp-dir EXIST)

[thenewguy]

How do I make an if statement that checks if a directory does exist?

if (c:\\newguy exist (true))
   {
       //code here
   }

You could use "SetCurrentDirectory(...)": http://msdn.microsoft.com/en-us/library/aa365530(v=VS.85).aspx and test if it failed or not.

Or you could use "CreateDirectory(...): http://msdn.microsoft.com/en-us/library/aa363855(VS.85).aspx and if it fails with ERROR_ALREADY_EXISTS then you know there is a folder there.

is that command:
CreateDirectory("C:\\newguy")
or somthing else?

Use PathFileExists(_T("c:\\mydir")) API exportat din shlwapi.dll. Works with files too.
CreateDirectory() could work, but why bother with that and create useless directories in case the directory does not exists already?

btw way I do Windows Forms C++/CLI Some call it CLR I think. Does the same command work?

And just to clearify the command is:

PathFileExists(_T("c:\\newguy"));
or

if (PathFileExists(_T("c:\\newguy")))
{
code here
}

my favorite way in windows api is to call GetFileAttributes. e.g.

if (GetFileAttributes(_T("c:\\newguy")) & FILE_ATTRIBUTE_DIRECTORY)
{
     // directory exists
}
else
{
    // handle error
}
