VB.Net ScreenSaver Question (Preview, /p) - Need Help Deperately

I am creatign a screen saver and am having a problem with showing the screensaver form in the preview pane. The code works correctly in the the form does display within the preview window. I created a simple for for testing called Preview that only had a label on it and the text "This is a Test" is hardcoded. By doing this I now that it is not other code I have written that is causing this. The problems I am having are:

1) The Preview form shows up in the preview window, but it goes away after displaying the form.
2) Although it does show up in the preview window, it does not show any of the controls on the preview form. A label that says "This is a Test". The fom shows on the screen, but there is not text on the scree either.

I have the following code for that /p parameter:

Case Is = "/p"

Try
Dim style As Integer
Dim commonVideoSS As New Common
Dim PreviewHandle As Integer = Int32.Parse(CTy pe(args(1), String))
Dim corners As Win32RECT = New Win32RECT

If commonVideoSS.M ediaPlayerSetup (frmVideoSS.wmp VideoSS) Then
'Get WindowRec for preview window
corners.GetClie ntRect(PreviewH andle, corners)

'Reset form to size of preview window
frmPreview.Wind owState = FormWindowState .Normal
frmPreview.Widt h = corners.Width
frmPreview.Heig ht = corners.Height
frmPreview.wmpV ideoSS.fullScre en = False
frmPreview.wmpV ideoSS.Width = corners.Width
frmPreview.wmpV ideoSS.Height = corners.Height

'Set the style
style = GetWindowLong(f rmVideoSS.Handl e.ToInt32, GWL_STYLE)
style = style Or WS_CHILD

'Set properties so form displays in preview window
SetWindowLong(f rmVideoSS.Handl e.ToInt32, GWL_STYLE, style)
SetParent(frmVi deoSS.Handle.To Int32, PreviewHandle)
SetWindowLong(f rmVideoSS.Handl e.ToInt32, GWL_HWNDPARENT, PreviewHandle)
SetWindowPos(fr mVideoSS.Handle .ToInt32, 0, 0, 0, corners.right, corners.bottom, SWP_NOZORDER Or SWP_NOACTIVATE Or SWP_SHOWWINDOW)
End If
End Catch

Thanks,

Any help will be appreciated.

Hello everyone, does anyone know a way to stop the screensaver under linux from starting up while a certain process is running? I need this because I experience a memory leak while recording wav-files every time the screensaver starts. It is a Tkinter application, btw. Any help would be very appreciated. Thanks

Does anyone know what the command line argumentto launch a screensaver's options/configuration dialog is on Windows XP Pro? From most of the example source code I can find on the web, it would seem to be '/c' but that does not seem to work for the screensaver I have written. I've tested my code and if '/c' is the first argument then the options dialog is launched but Windows XP does not seem to be supplying the '/c' argument when I...

I have been given an unusual task to create a Windows Service to do something periodically to make the screensaver timer reset.

I've written up this neat screensaver, but it has a few bits of ugliness to it ... 1. I both know how to get the handle for a preview and the handle for the window to display a settings dialog box. I am told to set the settings and preview window as a child of the preview or settings windows given a handle to the parent window either the preview or settings.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
