Creating a button at Runtime
You can create a button on a dialog at runtime in few steps.
Step 1: Create an instance of CButton. Write this line in the header file of your CDialog derived class CButton m_Button;
Step 2: Define a resource ID. #define MyButton 11111 . I have defined this resource id as a global variable in my cpp file. You can define in your resource's header file.
Step 3: Now get the size of your dialog and create the button. Write this code on OnInitDialog of your dialog class:
// Creating a button on runtime
RECT rc;
GetWindowRect (&rc);
rc.bottom += 30;
MoveWindow (rc.left, rc.top, rc.right-rc.left, rc.bottom-rc.top);
// Convert to client coordinates
ScreenToClient (&rc);
// m_Button is of type CButton and is a member of CMySheet
m_Button.Create ("&Runtime Button", WS_CHILD | WS_VISIBLE | WS_TABSTOP,
CRect (5, rc.bottom-30, 120, rc.bottom-5),
this, MyButton);
