I know that if I used PlainText, this problem wouldn't happen. But I have to use UnicodePlainText because my file is Vietnamese, it needs font Unicode.

That depends on what WTL features it uses. WTL::CString is a clone of MFC::CString so that won't be a problem to drop it into an MFC project. If it uses windowing classes, it will depend on whether it's a stand-alone control (like say CHyperLink). --Mike-- Visual C++ MVP :cool: LINKS~! Ericahist | 1ClickPicGrabber | NEW~!

Thanks to the Internet, we now know that this is not true.

well, I am not too sure about WTL->MFC, but you can fix the compilation error by putting #include "stdafx.h" at the top of the file or select "not using precompiled header" in projectsettings->C/C++ -prakash

I'm really sorry! I want to convert a string from CString(MFC) to LPCTSTR but the example is really stupid( it was written in WTL !!!). Now I wonder how to use a WTL class ( written in WTL,used WTL CString ) in a MFC application. The class is so important and i need it in my MFC project.However,it was written in WTL using WTL CString.Help me!!

rand()/RAND_MAX. Not exactly working. Integer arithmetic here. :) -- modified at 14:13 Monday 10th October, 2005

How about 1 divid by the system generated random number? So, if the system generated number is 10 => 1/10 = 0.1 100 -> 1/100 = 0.01 & etc.

Take a look at the Floating-Point Functions[^]. -- jlr http://jlamas.blogspot.com/[^]

Can you tell me a little more?I searched in MSDN but I could't find the way to solve this problem.Thanks
