Converting CString to const char* in UNICODE environment 1

[titanandrews]

Hello All,
I have come to the conclusion that strings in C++ are a pain in the ass. Why can't they all be UNICODE? Why is there 50,000 string classes?
Ok, I'm over it now... Could someone please tell me how to convert a CString to a const char* in UNICODE environment? The following code:

int retValue = system(myCommand.GetBuffer(myCommand.GetLength()));

works fine in a non UNICODE environment, but in UNICODE enabled environment, I get this from C++ compiler:

error C2664: 'system' : cannot convert parameter 1 from 'unsigned short *' to 'const char *'
        Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

I tried reinterpret_cast, but it just gives me garbage.


many thanks,

Barry

WideCharToMultiByte() can convert a Unicode string to a char * (Where you can specify the destination codepage).

Also wcstombs() can do the job.

Yes, there are a lot of string classes and functions for string manipulation ... and it is pretty confusing.
It's like going to the supermarket to buy soup : If you don't know anything about soup you are lost. You will have to read all the text on the packages, decide for one, bring it home to your lab and test it ... Much easier if only tomato soup was available ;-)

The easiest way to convert between the various string variants is using the MFC MBCS/Unicode Conversion Macros.
