I fixed the code so that it works... You will need to check and make sure you have the image listed on the last line...

Code: Select all

Global hwnd
Global transparent
Global Wait
TWait=5000
Global Start

Procedure MyWindowCallback(WindowID, Message, wParam, lParam) 
  Result = #PB_ProcessPureBasicEvents 
  Select WindowID
    ;Case WindowID(1)
    Case WindowID(2)  ; splash window
      Select Message
        Case #WM_NCHITTEST
          Result=#HTCAPTION
        Case #WM_TIMER
          Result=0
          Select wParam
            Case 1 ; fade in
              If transparent<255    
                transparent +1
              ElseIf transparent=255
                killtimer_(hwnd,1)  ; stop, fade in ready
                SetTimer_(hwnd,2,TWait,0) ; set pause
              EndIf
              SetLayeredWindowAttributes_(hwnd,0,transparent,2)    ;
            Case 2  ; pause ready
              killtimer_(hwnd,2)  
              SetTimer_(hwnd,3,3,0) ; set fade out
            Case 3  ; fade out
              If transparent>0    
                transparent -1

                Start=1 ; start main app
              EndIf
              SetLayeredWindowAttributes_(hwnd,0,transparent,2)    ;

No problem at all.

Beach,

Nice splash screen code! One thing - you need to put an End statement before the last line (Logo: IncludeBinary...), or you will get a fatal error when the program tries to "execute" the image data!

Regards,
Eric

Nice splash screen code!

That code was not mine... I just adjusted it so it would work.. someone did do a good job though...

Ahh...

missed that one - thanks!

Very nice.

Needed to alter 3 lines to avoid it crashing on my system though. The problem was that closing the app window caused the callback proc to investigate the closed splash window.

Code: Select all

Global transparent 
Global Wait 
TWait=5000 
Global Start 

Procedure MyWindowCallback(WindowID, Message, wParam, lParam) 
  Result = #PB_ProcessPureBasicEvents 
  Select WindowID 
    ;Case WindowID(1) 
    Case hwnd  ; splash window ;***
      Select Message 
        Case #WM_NCHITTEST 
          Result=#HTCAPTION 
        Case #WM_TIMER 
          Result=0 
          Select wParam 
            Case 1 ; fade in 
              If transparent<255    
                transparent +1 
              ElseIf transparent=255 
                KillTimer_(hwnd,1)  ; stop, fade in ready 
                SetTimer_(hwnd,2,TWait,0) ; set pause 
              EndIf 
              SetLayeredWindowAttributes_(hwnd,0,transparent,2)    ; 
            Case 2  ; pause ready 
              KillTimer_(hwnd,2)  
              SetTimer_(hwnd,3,3,0) ; set fade out

I is always recommended to put the IncludeBinary into DataSection/EndDataSection.
This way you don't need to worry about end statements and such, because it is not included inside the executable code.
