SWP_FRAMECHANGED   Sends a WM_NCCALCSIZEmessage to the window, even if the window's size is not being changed. If this flag is not specified, WM_NCCALCSIZE is sent only when the window's size is being changed.

SendMessage(hExitBut, WM_SETFONT, GetStockObject(SYSTEM_FIXED_FONT),0)

because the IsDialogMessage( ) is in the GetMessage loop below, you can put WS_TABSTOP in a control's style to have that control be a Tab Stop. Tab Stop Order is set by the creation order of the Tab Stop controls Since this is the first control with a WS_TABSTOP it is FIRST in the Tab Stop Order, hEdit1 will be next}

SetWindowLong(hExitBut, GWL_USERDATA, 1)

Every window has 4 bytes (integer) of "User Data", which you can set and read with SetWindowLong and GetWindowLong, you might think of this user data integer like the "Tag" property of controls in the VCL. Here I will use the Exit buttons user data as a boolean to signify if the button is visible, see the ChangeStyle procedure above

SetWindowLong(hExitBut, GWL_ID, ID_ExitBut)

control ID numbers are sometimes used in system messages, like the WM_DRAWITEM message, ID can also be used in the WM_COMMAND. . Normaly you would just put this ID number in the hMenu parameter of the CreateWindow function, I do this here to show methods for the SetWindowLong

SETWINDOWPOS

SWP_FRAMECHANGED  &H20

Applies new frame styles set using the SetWindowLongfunction. Sends a WM_NCCALCSIZE message to the window, even if the window's size is not being changed. If this flag is not specified, WM_NCCALCSIZEis sent only when the window's size is being changed

If you have changed certain window data using SetWindowLong, you must call SetWindowPos for the changes to take effect. Use the following combination for uFlags: SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED.

(GWL_USERDATA  (-21

Sets the user data associated with the window. This data is intended for use by the application that created the window. Its value is initially zero.
