I am creating an install program for my screensaver that I made. The problem I am having, is I want the windows screensaver dialog pop up, with MY screensaver set as the active one, displayed in front of me, like what happens when you right click on a screensaver to install. What do I do?

I looked for examples of screensavers on Code Project here, and I find screensaver source codes, but no install program source code.

I hope you know what I'm referring to, and I would appreciate any help. Smile | :)

Write to the registry: "HKEY_CURRENT_USER\Control Panel\Desktop" with the "SCRNSAVE.EXE" value name. This holds the path of your screensaver executable file.

Hope this helps,

Does that cause the screensaver dialog box to pop up automatically?

No. To do that you need to use Rundll32.exe to run the "display.cpl" control panel application opened to the screensaver page (page 3, 0-indexed) Use this command line:

rundll32.exe shell32.dll,Control_RunDLL desk.cpl,,2

You're welcome. Smile | :)

I will mention that that command line string has worked since Win95, but might show the wrong page. Just change the number at the end of the string to get the correct page Smile | :)

I'm very interested to know where you learned something like that ... That's not something one can discover by himself, is it ?

MSDN has a heck of a lot of useful information Wink | ;)

You just gotta know where to look Smile | :)

And some words are not indexed. I've looked for things before that I knew should exist but couldn't find. Later on I'd be searching for something different and accidently stumble across what I was looking for earlier, and the word I was searching for would be right there staring at me. The MSDN search engine is very elusive at times.

Aah yes, but I use the CD version. HtmlHelp creates its own index Smile | :)

The first thing you'll need to do is update HKEY_CURRENT_USER\Control Panel\Desktop\SCRNSAVE.EXE with the name of your .SCR file. Then you can run RunDLL32.EXE shell32.dll,Control_RunDLL desk.cpl,,1 using ShellExecute() or CreateProcess().

Edit: it took over five minutes for this post to actually go through. By that time, the answer had already been submitted. I hate slow posts!
