CString __filepath;<br />
__filepath = dlg.GetPathName();<br />
int x = __filepath.GetLength();<br />
char *filename;<br />
filename = new char [x];<br />
for (int i=0;i<x;i++) {<br />

ie char *filename; would be TCHAR *filename;<br />
filename = new char [x]; would be filename = new TCHAR [x]; and <br />
filename[i] = (char)__filepath.GetAt(i); would be filename[i] = (TCHAR)__filepath.GetAt(i);

This is not a good way.. Use _tcscpy instead
