Thread: common controls

for my own personal use, I'm making a header file that creates some of the more common controls such as buttons, text, etc. This is how I create one of the controls:

Code:

HFONT hfDefault;
HWND current;
current=CreateWindowEx(0, "BUTTON", caption,WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON,xpos, ypos, length, width, hWnd,NULL,NULL, NULL);
hfDefault =(HFONT)GetStockObject(DEFAULT_GUI_FONT);
SendMessage(current, WM_SETFONT, (WPARAM)hfDefault, MAKELPARAM(FALSE, 0));

but i have a few questions.

1.)How do you delete the button off the window?
2.)How would you go about changing the WS_VISIBLE option?

To get rid of/get back the WS_VISIBLE, you use SetWindowLong(...), like this:


SetWindowLong(hwndButton, GWL_STYLE, WS_CHILD);

to get it back:

SetWindowLong(hwndButton, GWL_STYLE, WS_CHILD | WS_VISIBLE);


You will have to use UpdateWindow(hwndOwner); or something like that to update the visibility of the button when you change its style.

Hide / show the button from view with ShowWindow() .
DestroyWindow() to kill it compleatly.
