Closing MainWin conditionally?
« Thread started on: Aug 30th, 2015, 6:24pm » |

I know, I shouldn't be using MainWin 
But is there a way to close MainWin without using the compiler instruction nomainwin?
I would like to close MainWin conditionally...
...or hide it or open it minimised.
Thank you

Reading between the lines, are you trying to discover the mainwin's window handle? With that you can easily close it, hide it, minimize it, move it etc. using regular Windows API calls.
You can get the mainwin's handle using an embedded BBC BASIC statement:

In the end I used the CloseWindow function to minimise the window instead of the DestroyWindow function that kills the program. This is because I wanted to get rid of mainwin but still wanted to display a notice (using the LB "Notice" command). It still shows the window being minimized, but that's okay.

There's no point in calling DestroyWindow, since END has the same effect (in a compiled EXE).
Personally I don't like calling CloseWindow simply because it is misleadingly named (it doesn't close the window). My preference is to call ShowWindow with the SW_MINIMIZE parameter because then it's obvious what you are doing.

Wouldn't hiding the window be better?

Used the following. Thank you :)
Code:calldll #user32, "ShowWindow", hmainwin as long, 0 as long, r as boolean
I think I need a reference book for all these API calls ;)
