Map the button to CButton (for ex m_button) using the classwizard.
Now u can use m_button.EnableWindow(TRUE) to enable window or m_button.EnableWindow(FALSE) to disable the button. Smile | :)

There is no such ready to use method that allows you to change the caption bar. You will have to owner draw the items that you would like to change the color of. Look into the examples of code project.

The Noob of Noob Questions

I am a C# programmer, using VS 2003. I found C++ DLL code on the internet and created a new C++ project to clean up the code to modern standards. When i compile the new project i am getting hundreds of errors. It appears nothing is recognized by the compiler.

When i put the cleaned up code in the original project, replacing the original files, eveything works fine. So i concluded that certain project settings needed to be configured. So i go back to my new project and try to make the project settings the same. But when i compile i still get hundreds of errors.

What do i need to set up to have compile success? Why does C++ have to be so hard to use?

It sounds like the original project may have had less strict warning and errors settings than your new project. What you may want to do is open two instances of Visual Studio, one with the old project and the other with your new one. Compare the settings, side by side.

Bjarne Stroustrup, the creator of C++, had something like this to say: "The C programming language made it easy to shoot yourself in the foot. With C++, you blow off the whole leg."

C++ is a powerful language. Unfortunately, with that power, can come great difficulty.

Functions aren't mutable, member variables are, for example:

class Bob
{
mutable int m_int;
void func() const { m_int = 1; }
};

In the parent thread declare a pointer variable to the child thread dialog class.
pass that pointer to the child thred and get it initialized with the dialog class object.
use that pointer form the parent thread to set the edit control txt.

But, I dont think it is a good design to manipulate the child thread controls from parent thread. chil thread has to be idependent from perent.

Yes,I did like that only.The error shows when the control finished the execution of whole program and it goes to InitInstance() in app class.And then after tht function the control passed to disassembly and showed this error.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
