You should NEVER do this. Your application is running on a shared system and you've written your app to NOT work and play nice with others. When the user hit's Alt-Tab to switch to another application, you've just limited them to the screen size your app imposed on the entire system. Do that on any of my machines and I'll uninstall your app and burn the install CD.

You can't. At least, I've never found a way to do it.

I wouldnt change the screen resolution on any normal app, but this is for a game I am attempting to write. Most games I have seen on my PC change the resolution and take up the whole screen.

If you have another sugestion how my app can take up the whole screen and remain the same visually then please let me know.

Thanks

That's because they use DirectX to do so. DirectX doesn't use the normal screen you see with your Desktop. In a Full Screen mode, it creates an entirely seperate drawing surface, kind of like an entirely new Desktop, complete with it's own video card parameters.

Thanks Marc,

Basically, he's getting a handle to the desktop's listview control then using low level API messages to query the listview into a memory mapped area. Similarly, he's using messaging to the listview control to set the positions. Pretty tricky. Pretty scary.

There's several third party apps out there that save/restore icon positions. I'd see if one of those can be executed directly from your app, or contact the author of one of them for help.

The point of MDI is to be able to open multiple documents. You either want SDI (single document interface) or you need to test if the form is already open. Sort of defeats the purpose of MDI though.

How to change a homebrew screen saver's title?

Hi there,

I have a farely simple question that I can't seem to find the answer
to.

I've got a C# Winforms application that after building results in an
executable. This executable is then renamed to an .scr file and used as
a Screen Saver.

How can I get this file to come up with a different name than the
filename in the dropdown list in Display Properties/Screen Saver? My
screensaver's filename is "screensaver.scr" and the dropdown shows
"screensaver", instead of a more friendly name "My Beautiful Screen
Saver".

I've searched everywhere but all I get is things that refer to a
StringTable, where you have to add a row with ID 1 and name "title" and
value "screensaver title". This should result in a different Title
being used in the dropdown mentioned before. However, I don't know how
to add this StringTable to my C# project.
When I open existing .scr files (that come with windows) in VS.Net
using the Resource Editor I see a StringTable that indeed contains this
ID 1 row, but when I open my own executable, I don't even have a
StringTable.

I hope someone can advise me on what to do.

Thanks in advance,

Mark

I have not a tested idea to point so I'll write two idea that i have based on similar situations. maybe they can help. Sorry if it is rubbish

1)You can prevent your application from loosing focus. So when win key is pressed your app must loose focus. If you deny that maybe it is a solution. I believe it is a wrong solution though

2)In previous years i had wirtten an app that hooked on every key and mouse move. Maybe if you create a hook handler and when win key is recognized, you can just consume the event so it wan't be passed to the explorer. But I believe this must be already the case for the exlorer so you is going to handle the message first I don't know.

Aain sorry. Just some ideas.

Microsoft provides an article How to use Kiosk Mode in Microsoft Internet Explorer[^], explaining how to replace the standard Explorer with the IE in the "Kiosk-Mode".
Maybe this article will give you an ídea.
