Hi All!

I have one problem, please suggest.

C++

CString str = _T("CodeProject\Application");

int l_Temp = str.FindOneOf(_T("/\?<>|:*")); //I'm searching for all these characters

if(l_Temp != -1)
{
  AfxMessageBox(_T("Invalid Name"));
}

It is able to searching all characters, but '\' is not searching.

Please do the needful.

Thanks
Sam

By the way, you should also have a double backslash in CodeProject\\Application.

Solution 1

The backslash (\) must be followed with a second backslash (\\) when it appears within a string, see Escape Sequences[^]

In your case there need to be three backslash in the string, two for the backslash itself and one for the question mark (?).

C++

int l_Temp = str.FindOneOf(_T("/\\\?<>|:*"));

Solution 2

use '\\' not '\'
ex:-
if(csProfilename.FindOneOf(L"\\/:?<>\"|")!=-1)
