Hee now than i saw your message.. prev, I got the same problem with the isDigit() function so I got :mad: and create a iIsNum(CString string) function using VC++ ver 6 BOOL iIsNum(CString string) { int strLenght = string.GetLength(); bool _isnum; CString chr; for (int i = 0; i < strLenght ; i++) { chr = string.Mid(i,1); if(chr >= "0" && chr <= "9") _isnum = TRUE; else { _isnum = FALSE; break; // no use search for other char } } return _isnum; } Hope you still can use this function ~~~
