I have the following code.  I need to make sure that is in upper case.  How do you do this with basic_string:

typedef basic_string<TCHAR> CStr;

Then somewhere in my function I do the
following:

CStr strDriveSelected;

strDriveSelected = OLE2T( strDrive );

What is the best way to conver it to
an upper case.  So if strDrive is "a"
strDriveSelected becomes "A"

THanks

Method 1
You can use CharUpperBuff(LPTSTR lpsz,
DWORD length) to convert the string into uppercase
Method 2
Use CString::MakeUpper to convert the string into uppercase after assigning it to a CString variable.

I'm not using MFC.  My project is an ATL not MFC based.  Is there an ANSII function to do this?

Thanks

Hi,
This code should help you:
_tcsupr(const_cast<TCHAR*>(strDriveSelected.data()));

Not really!  Don't ever do that.  That can mess up other strings.

Please, don't use toupper. It doesn't work in Finland for example. We have letters like åäö and their uppercase equivalents ÅÄÖ.

toupper works only for a to z.

The STL toupper() template function allows you to specify a locale so that this can be made to work in any language (and with any character representation.)
