Qt would be a nice tool for GUI development. Qt has both paid and open source versions. Qt source code is protable (if coded carefully) to other operating systems like Windows and Mac as well. http://qt.nokia.com/products[^]

Ok.... in Qt we program in C++...at any time , if I wanna attach any C- codes, whether it makes any complication or not.Actually I know something about qt, I've created small GUI's like small dialog widgets and all.. So according to you continue with qt is best.!!!

Anyway
thank you.

I think you can reuse you C code in Qt without much problems. Give it a try.

I'll second Qt - Qt's nice. And you've got QtCreator, which is a nice Qt-centric IDE.

Just in case you have doubts about QT... I would definitely recommend QT! Smile | :)

Regarding development tools, KDevelop[^] is an IDE supporting Qt, GTK and wxWidgets.
But I usually stick with Eclipse[^] for most part of C++ development.

Hope this helps.

Strings revisited:CFile and CStdioFile [modified] - Sort of solved

So having bashed my head against the wall and having done as much reading as possible, I'm still confused. Confused | :confused:

My understanding from other posts was that char* is an array of single bytes, and that in VS2005, CString is Unicode. But I seem to have a mixture of this...

I'm doing:

void CMyClass::MyFunc()
{
	CFile myFile(L"C:\\MyFile.txt", CFile::modeRead);
	char* pchContents = new char[myFile.GetLength()];
	myFile.Read(pchContents, myFile.GetLength());
	CString myString = (char*)pchContents;
	myFile.Close();
	delete[] pchContents;
}

but myString is strangely spaced out and have odd bits added to the front and back. Does this mean the contents of pchContents got turned into wide characters?

Anyway, the problem is that after a load of other operations, I have to turn myString back into char*. But wcstombs_s fails because it encounters wide characters.

What I really don't get is the fact that this whole thing works if I don't read from file into myString but build it up using MSXML and cast the resulting BSTR into CString. I thought all CString was wide, so how come I seem to be having two different flavours?

=========================================

The long and the short of it is that I now have a working piece of code.
I'm not entirely sure what happened.

Basically, I was reading in a file (xml file) edited using Visual Studio 2005. I rewrote the thing in notepad and it works fine now.

I guess my code was right in the first place, but the file I was reading wasn't.

I'm guessing that Visual Studio added some MBCS into my file outside of what I typed and that was tripping up my wcstombs_s.

Am I right?

try

CString myString(pchContents);

or if you use assignment operator first convert pchContents to widechar using mbstowcs like functions and assign resulting widechar pointer to CString obj.

assigning BSTR into CString works as BSTR is defined as WCHAR*.

wcstombs_s will definitly work, provided you use it for unicode string to multi byte converstion.

Thanks, I have read this.
The trouble is, I don't know how to tell if I'm working in SBCS, DBCS or Unicode...

Or at least I thought I knew but it looks like I don't... Confused | :confused:

I wonder if it's because CString's constructor takes MBCS and Unicode, so reading from CFile does one version and writing using MSXML does the other? Confused | :confused:

Almost, but not quite, entirely unlike... me...

CString become CStringW if your project setting is UNICODE and it becomes CStringA if the project settings is Multi-byte.

I think my little grey cells are just about OK with that...

But, then, what do you think about the fact that I have 2 CStrings, one is apparently CStringA and the other is CStringW in the same project, which I am quite certain is Unicode. Confused | :confused:
