You can use of CStringMid or CString:Left.

You can use CString::ReverseFind() to get the zero based index of the last backslash and then truncate it with CString::Mid().

You can also use _splitpath() to split a path into its contents and then rebuild the string.

Something like the snippet below
This is at the top of my head and I haven't tried to compile it, but you should get the idea anyway...

CString FullPath = _T("C:\\abc\\cd\\as.txt");
CString DirPath;
int nPos = FullPath.ReverseFind( _T('\\') );

if( nPos >= 0 )
{
    DirPath = FullPath.Mid( 0, nPos + 1 );
}

Hi,

Roget scoltz has given a nice solution. Did you tried that.

CString FullPath = _T("C:\\abc\\cd\\as.txt");
CString DirPath;
int nPos = FullPath.ReverseFind( _T('\\') );

if( nPos >= 0 )
{
DirPath = FullPath.Mid( 0, nPos);
}
AfxMessageBox(DirPath);

Roger said to you how to do it, you then comeback to ask for code. Now, there's something else which is utterly similar, but you want someone else to do it for you.

Why don't you write your code yourself? Today is a good day to start.

The idea was given to you here[^]. Why don't you try to devise a logic?

If you want to strip down to the first directory from the root, then why not use CString::Find() instead of CString::ReverseFind() ?!

You're wasting your time, Rajesh. He just wants a quick fix, he's too lazy to attempt to understand what he's doing or what he should be doing.

I'm terribly sorry, but this is logic on kindergarten level.
If you sincerely do not understand, or you're too lazy to figure out why you got that result and what to do to fix it, I suggest you find another profession.

Best of luck. Rose | [Rose]

Why do you use Find, instead of (suggested) ReverseFind?
