Convert CString to char*
-
I'm trying to find an easy way to convert a CString to a char* without having to do it character-by-character. I've tried memcpy unsuccessfully. Anyone have any tricks?
CString provides a (LPCTSTR) cast operator for this.BTW, what are you trying to achieve ? can't you just use CString::operator[]() or CString::GetAt() to retrieve a character in the CString object ?

I want to get the entire string into a char array in case I can't figure out how to do something else.

NO, definitely not !
GetBuffer()is not there for casting purpose ! Moreover, the OP seem not to really know what he wants that for, so instead of saying amen to a query-for-code, better understand why such a thing is asked for... I'm more likely to think he's trying to iterate on every characters of the string, so no need for cast for this ; a simple use of the[]operator would do ! BTW, I'm almost certain that Roger Allen (which is also a great codeproject member) would not reply so nowadays... notice that he replied so, but it was in year 2000 ! at last, read this[^] and tell me if you see somewhere in Microsoft recomendations to useGetBuffer().[VisualCalc][Binary Guide][CommDialogs] | [Forums Guidelines]

exactly. As I am suspecting the OP to have asked this for a darken reason, I'm not sure casting the CString object would be worth it...

I was merely posting a link to a thread that was of the same subject - I was not involved with any of those thread posts I thought it would be helpful to USAFHokie80 here.. Regards, --Perspx

Yeah... GetBuffer doesn't work. But this works: char* str = (char*)(LPCTSTR)str2

That's a horrible cast, and a good example why casts are bad. If you needed the cast to get that to compile then you did something wrong. It should be const char* str = str2; If your CString is always based on a "char" character type, then you should be using a CStringA. Mixing generic and fixed character types negates the usefulness of generic character types (i.e. your code will fail on a Unicode build). Mark
