Help: Add strings

wrydds

CString s1;
GetCurrentDirectroy (_MAX_DIR, s1.GetBuffer (_MAX_DIR));
CString s2 = "s" + s1;
Debugging found: s1 is a path, assuming "f;\test", but s2 = "s" + s1, but it is equal to "s", which means that s1 is not added! what happened? Confused.

Is s1 not empty?

wrydds

Ok, all printed out. So strange

Is there something in s1?
After s1.GetBuffer(), don’t you want ReleaseBuffer?

Add before adding
s1.ReleaseBuffer();

GetCurrentDirectroy

You seem to be wrong, it should be this:

GetCurrentDirectory

CString s1;
GetCurrentDirectory(_MAX_DIR,s1.GetBuffer(_MAX_DIR));

CString s2;
s2.Format("s%s",s1);
