Break the question into steps. Does GetParent () actually return the window you are expecting? Is edt1 still valid? Did you assign a number to it that no longer matches the ID of the control you are trying to access? Is that control actually being created? You can check this using spy++ etc to see if it (a) exists, and (b) has the right ID. Etc. Iain.

You're using C++ to output to the console, and C to output to the file. Use iostreams instead. #include <iostream> #include <fstream> #include <string> using std::string; using std::ofstream; ... string s("This is a test of the veracity of my system"); ofstream op("c:\\test.txt"); op << s; // can call op.close(), but the destructor does it anyhow.

Use C++ instead of C. Longer reply in ATL/WTL/STL. I should add that if you're stuck with C files, you can use the c_str() function of a std::string to get a const char *.

No, you can't directly change the parts. You must use an assignment, e.g. std::complex<double> c(1.0, 2.0); ... c = std::complex<double>(c.real(), 3.7);

I'm using C++ complex template class. I got problem when I declared an array of complex numbers. e.g. I declared it like this: CArray, complex> ptArrayComplexNumber; The declaration above is not right for the VC compile. So I changed to CArray, float> ptArrayComplexNumber; This one is good for compile, but I can't do insertion complex number into it or other actions. Do you know how to do it?

What do you mean by complex classes? Build a man a fire, and he will be warm for a day Light a man on fire, and he will be warm for the rest of his life!

Using Win32 SDK BOOL EnableWindow( HWND hWnd, // handle to window BOOL bEnable // enable or disable input );

Actually, I have a big integer value, larger than 80 bits which I can't use DOUBLE to hold this value and print it out. Now I have a array to hold this value by binary integers(0,1), then I need to convert it to another array which hold decimal integers(0 to 9) to present this large value. Because I can't use power of 2 ( if I have 256 bits, then I can't hold the it), I have touble to convert it. mIchAel Liu __________________________________________________________ The secret of business is to know something that nobody else knows. ;)

Tomasz is cool! it has to be said, I see him answering so many questions!

Thank you. It's a good point. mIchAel Liu __________________________________________________________ The secret of business is to know something that nobody else knows. ;)

Also, if the GetItem implementation is in a C file do not forget the extern "C" stuff: extern "C" { #include "Header_in_C_That_Contains_GetItem.h" } Best regards, Alexandru Savescu

Thx mIchAel Liu

Wow - you must have an MSDN subscription. The SDK should set up it's paths so that it is automatically integrated with VC. Christian I am completely intolerant of stupidity. Stupidity is, of course, anything that doesn't conform to my way of thinking. - Jamie Hale - 29/05/2002

The problem is this ghost windows only happened in XP system, not Win2000&98/95. And began at Oct.2001, MSDN started to say something about the ghost window in its doc, but no more infomation to deal with ghost windows. (read the WM_PAINT in MSDN). Thanks mIchAel Liu

why not fix the hang? I happen to like the ability to close programs that are misbehaving!

I never did program for XP specific, still a guess. Are window styles (::GetWindowLong()) same for Ghost(Excutable Mode) & Non-Ghost(Debug Mode) ? If not, make them the similar styles. Use Spy++ to check the styles. Thanks, Ramu
