Mid Function

[Shelyn]

Hi All,

What is the Mid Function for Visual C++? Anyone has example for it?

Thanks in advance.

CString::Mid(...)

I know CString::Mid and this is the example I found from MSDN:
Example
The following example demonstrates the use of CStringT::Mid.

//typedef CStringT< TCHAR, StrTraitATL< TCHAR > > CAtlString;

CAtlString s( _T(&quot;abcdef&quot );
_ASSERT( s.Mid( 2, 3 ) == _T(&quot;cde&quot );


But I don't know how to use it. Can you write a simple code for me? Sorry, I am really not familiar with C. Thanks.

Ok. What do you wish to accomplish?

I just want to write the mid function to retrieve the character from the string. Like VB we just need to write
Mid(string, int, int), but for C++ I don't know how to apply the Mid function.

It is quite similar though Mid is a method to the CString class, not a standalone function.

Ie
VB:
someString = &quot;ABCDEFG&quot;
someOtherString= Mid(someString, 2, 3)
' someOtherString is now &quot;BCD&quot;

VC++
CString someString (&quot;ABCDEFG&quot;
CString someOtherString = someString.Mid(2, 3)
// someOtherString is now &quot;BCD&quot;

Do I need to include any library? Coz when I wrote CString S, it gives me error that Undeclared identifier.

Well, CString is part of MFC, ie you shuold make an MFC application.

Use the Visual Studio's AppWizard to generate an MFC application for you.
