Random Images Screen Saver - Download Link does NOT work

I realise that this is years after the article was written .... But, as of 10-Nov-2004, the download link does NOT work.

Unnecessary code, but useful!

In the PromptIfPasswordNeeded function of the ScreenSaverUtils.pas unit, it is not necessary to check for and obtain the 'Control Panel\Desktop\ScreenSaveUsePassword' value in the registry. The VerifyScreenSavePwd function in 'password.cpl' does this automatically for you. On the other hand, the registry code in the PromptIfPasswordNeeded function produces the correct behaviour on NT based machines (i.e. if NT then don't call the VerifyScreenSavePwd function), and so if you remove the registry code, you will need to check the OS yourself (with something like "if Win32Platform = VER_PLATFORM_WIN32_NT then ...").This is a case of seemingly unnecessary Borland code turning out to be quite useful. :) Mark Stevenson http://threads.codegear.com/threads/threads.exe/userall?commentid=28697 http://threads.codegear.com/threads/threads.exe/view?commentid=28697 2001-04-20T12:20:00-07:00 2001-04-20T12:20:00-07:00

Random Images Screen Saver - SystemParametersInfo - a query

I am trying to create a screensaver using Delphi 4 ( I realise that this code won't compile under Delphi 4 but I needed inspiration ! ) and I find that it works fine on Windows '95 , when the saver is activated one copy of the program is loaded and all is well with the world . In Windows '98 however I find that dozens of copies are run over and over again . I was hoping that SystemParametersInfo(SPI_SCREENSAVERRUNNING,1,@dummy,0); was the line I needed but it crashes out , causing windows ( either '95 or '98 ) to tell me my program has caused an error and will be closed down . Strangely the closing SystemParametersInfo statement telling Windows that the saver is no longer running causes no problems . Hmm.....Also is there a similar command to SetCapture , for intercepting keypresses , whether a form has the focus or not ? I have tried the FAQs but no luck . bereket tesfayohannes http://threads.codegear.com/threads/threads.exe/userall?commentid=28203 http://threads.codegear.com/threads/threads.exe/view?commentid=28203 2001-03-03T04:26:23-08:00 2001-03-03T04:26:23-08:00

Random Images Screen Saver - Bug OnMouseMove Procedure

If you press the cancle button on the screen saver password dialog box after moving the mouse you might see a littel bug.It could be fix this way. 1 Add this declerations in the private scection FMouseLock: Boolean; 2 Add this code on the FormCreate Procedure FMoseLock:=False; 3 In FormMouseMove procedure write the following code just before a call to close procedure IF not FMouseLock then begin FMouseLock:=True; Close; end else FMouseLock:=False; Corbin Dunn http://threads.codegear.com/threads/threads.exe/userall?commentid=27671 http://threads.codegear.com/threads/threads.exe/view?commentid=27671 2001-01-24T09:34:50-08:00 2001-01-24T09:34:50-08:00

re: Random Images Screen Saver - a complete screen saver example

Yup...I looked into the problem. Our server sends out a style sheet, and it adds stuff to the "pre" tag. However, netscape "forgets" it is a pre tag. I emailed the fix to our web team (fixing the style sheet will fix all documents!). Thanks letting me know about the issue.

re: Random Images Screen Saver - a complete screen saver example

The HTML that is included with the download looks OK in Netscape.When double-clicking on the file in the Explorer, NS complains that it can't find something (which happens every time I do this with any local HTML file), and the code snippets aren't surrounded with boxes but otherwise are formatted correctly.When loading the file in NS with File | Open Page, there is no message and the code snippets still look OK.Enough info for you? ;-) Thanks for posting the article -- I've been wanting to do a screen saver in Delphi for some time.Fred Corbin Dunn http://threads.codegear.com/threads/threads.exe/userall?commentid=27626 http://threads.codegear.com/threads/threads.exe/view?commentid=27626 2001-01-19T18:15:55-08:00 2001-01-19T18:15:55-08:00

re: Random Images Screen Saver - a complete screen saver example

geez...that isn't good. I'll tell our web guys. Netscape doesn't handle pre tag's right, I guess. We are supposed to use a certain "source code pretty maker" program to generate our snipplets. I just cut and paste. Thanks for letting me know.

re: Random Images Screen Saver - a complete screen saver example

Using Netscape 4.6, the lines of code in the boxes are flowed together, as if the line breaks are being ignored.It looks fine when using Internet Explorer.

re: Random Images Screen Saver - a complete screen saver example

Steve,I'm unsure of what you mean. You mean when you physically print the file, or is there something else wrong?
