I have variable:

char * str;

and m_str is a member of TextBox Control, its type: CString
And I want when I click on button, str will get the text in the text box.

I used:

str = m_str;

I know it's wrong, but I don't have any better idea. Can anyone help me please?

First you need to allocate memory for the char* str to point to.
For example:

char* str = new char[m_str.GetLength() +1];

That would allocate enough memory for a C-Style null terminated string.
After that you'll need to copy the contents of the CString m_str variable to the newly allocated memory pointed to by the char* str variable.

You can look this up on msdn.microsoft.com for more detailed information.

Best of luck.

: I can suggest you one moreway.
suppose you have a string csString.
and you want to convert it into a char* then....

char *string = new char[csString.GetLength() +1];
string = csString.GetBuffer(csString.GetLength() +1);
csString.ReleaseBuffer();
