Windows Programming Tips 'n' Tricks
This is a page where I am going to put a few tips 'n' tricks to use in windows programming, one reason is cos my memory sucks so it's a useful place to collate things that I find useful, and I thought some other people might find these useful as well so here you go. For a more comprehensive guide to windows programming, buy Charles Petzold's book Programming Windows 5th edition as it is excellent.
Activate Screen Saver Fixed Size Window
Here's a useful line of code to activate the screen saver, might come in useful some time.
SendMessage(GetActiveWindow(),WM_SYSCOMMAND,SC_SCREENSAVE,NULL);
Here's a nice one to turn the monitor off.
SendMessage(HWND_BROADCAST, WM_SYSCOMMAND,(WPARAM)SC_MONITORPOWER, 2) ;
I had a bit of trouble getting tab to work in my dialogs at first but here's how u do it (well, how I did it, there could be a better way). You have to use IsDialogMessage() in the main message loop. Here's an example of one of my loops implementing IsDialogMessage().
This is another thing that can be fun if you cant find out how to do it. Below is a link to a file that has a systray_add and a systray_rem function, I did not write this code so do not blame me if you have problems :) I have used these and it is working fine.
To get the window to dissapear when it is minimised is shown below :
There you go. Simple.
Here's a piece of code that you can put in a menu item case to toggle between a window item being always on top or not, obviously replace ID_FILE_ALWAYSONTOP with your menu item and replace the co-ordinates with whatever you want them to be,
To make a window a fixed size so the user cannot change it at run time, instead of using just WS_OVERLAPPEDWINDOW in CreateWindow or CreateWindowEx for the style, use WS_OVERLAPPEDWINDOW ^ WS_THICKFRAME.
