RE: [DUG]: Change the settings of the Taskbar
... reminds me of the saying: "there are two ways of being well off - one is to have more, the other is to need less" I guess I'm in the "have more" camp. Max snip You'd be surprised perhaps. I constantly experience problems with people's web pages at 800x600 that assume my screen has a minimum area. It is not that you get scroll bars, but that you don't. The pages are designed to fit on a minimum screen area and if your screen happens to be of less height then part of the page won't display and no scroll bars are displayed. People on 640x480 would have even more problems. I run IE with the full size button bar, the links bar and address bar and status bar, and that doesn't leave enough height on the 800x600 screen for some of these web pages that I visit. But I am used to screen area problems because I run a double height taskbar with the IE address bar and quick launch toolbars on the top row. Then I drag the IE address bar up next to the menu bar to give me extra height in IE but it still doesn't work with these web pages. Why do people assume your screen will always be 800x600 and your taskbar will always be a fixed height and you will have no other appbars? Some people run the Office toolbar on their screens as well. It is so simple to put scrollbars on your app or webpages when they don't have enough area available to display normally.

RE: [DUG]: Change the settings of the Taskbar
Indeed Patrick. And to further complicate matters we want to do this for some-one elses application. Personally I'd change screen resolutions and/or buy a bigger monitor - this sort of thing should only be an issue at 640 x 480. We could all have done so with the time we have spent not finding a solution.

RE: [DUG]: Change the settings of the Taskbar
Correction: this message gets sent to appbars when an application goes full-screen, but the mechanism of how an application tells Windows that it is going full screen is unknown to me, it is probably in the Windows function group in the API. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, 28 July 1999 13:56 To: Multiple recipients of list delphi Subject: Re: [DUG]: Change the settings of the Taskbar Quoting gajo [EMAIL PROTECTED]: OK OK, let me explain it to you again!

RE: [DUG]: Change the settings of the Taskbar
Be aware that ABN_FULLSCREENAPP is not a windows message. It IS a message, but it is sent to a special callback function that a taskbar sets up when it registers itself (and it uses SHAppBarMessage to do this). For your information, ABN_FULLSCREENAPP's value 2 (see ShellAPI.pas), which is the same as the value of the windows message WM_DESTROY. Try firing _that_ around your system ;-). The key seems to be that Windows seems to know when a window is being made full screen, and handles the sending of that message to the callbacks of the taskbar(s). As another application is creating the problem window, there seems to be no easy solution. MSDN suggests that creating special full screen windows (it doesnt say how) is not recommended. It says you're better to tell the user how to select the AutoHide property of the toolbar!

RE: [DUG]: Change the settings of the Taskbar
I thought the original issue was to test for when someone elses application was maximised, or became the foreground application, and then set the task bar accordingly. I agree this is not a very sensible thing to do, changing screen resolution is one better solution that comes to mind, but I still would have thought you could hook these messages and respond accordingly.
