how to use a timer
« on: April 16, 2018, 09:52:49 AM »
Hello

i'm  trying to make a splash screen which will time out in 5 secs

my preliminary code is below -- it does not exit after 5 secs?  any help appreciated

Code: [Select]

Actually, it does exit but only in 32 bits. Which means the code is viable (though unsafe). I think Charles has to step in.

Thanxx for the info, Mike
good to know that it works in 32bit

Hi Chris,

This is a display and fade routine, using the 60Hz frame rate as a time base. All you need to do is insert it at the start of Scene()

Code: [Select]
  'DISPLAY AND FADE OUT
  if not picking then
    static Counter '60Hz Frame counter
    counter++
    if counter>180 'AFTER 3 SECONDS
      int WindowOpacity
      int t=(counter-180)*255/120 '2 sec fade
      if t>255 then t=255
      WindowOpacity=255-t
      if counter=300 '5 SECONDS
        CloseWindow 'REQUEST SHUT DOWN
      end if
      'Set WS_EX_LAYERED on this window
      SetWindowLong(hwnd, GWL_EXSTYLE,
      GetWindowLong(hwnd, GWL_EXSTYLE) | WS_EX_LAYERED)
      SetLayeredWindowAttributes(hwnd, 0, WindowOpacity, LWA_ALPHA);
    end if
  end if

Hi Charles,

I applied your routine, compiled to 32-bit and 64-bit and the splash screen fades nicely out. May I ask two questions:
I used Set/GetWindowLongPtr. Does it matter?
How would the splash screen be applied in an application? I assume I have to create a Main Window and a Child Window which is the splash screen. Must I use different Scene() routines?

Thanxx Charles you are a maestro!

@Roland,  to apply this splash screen, i think you should use a main calling program with a main window
and call this Splash program as a dll.   so when the splash.dll exits it will not have any effect on the main program.

i maybe wrong, but i think this is doable?

Thanks Chris,

That answers Roland's second question.

I think it's doable. Strictly speaking though, You will also need to explicitly UnregisterClass, in a DLL. This can be done after the close of the message loop in WinMain.

https://msdn.microsoft.com/en-us/library/windows/desktop/ms644899(v=vs.85).aspx

I will add this to WinUtil.inc
Code: [Select]
  ...
  UnregisterClass @wc
  end function ; end of WinMain

Hi Roland,

I don't think it matters in this instance but we can adopt GetWindowLongPtr and SetWindowLongPtr as the standard.

Thanxx Charles

but when i placed the UnregisterClass @wc  into WinUtil.inc  , it did not work

the main dialog also closes after the splash screen faded away?

see the atteched files

Hmmm! This is not going to work, since it seems not to allow registration twice, even when the first is unregistered (dll window).

Will have to think of another way.

Hello Charles

i tried modifying this DialogWind.o2bas  to have the below code
but when i compile and run my pc display the message   " this app can't run on your PC "

Code: [Select]
     case IDM_Splash
                   Local hsplash as sys
                   hsplash= FindWindow("Splash", "")   'Find splash handle
                     if hsplash  then
                             PostMessage(hsplash, WM_CLOSE,0,0)   
                    else
                            Splash()
                   end if




and when i placed back  the original code (as shown below) it can compile and run without that message
wonder if you have the same problem if you added the above code.  the  windowsdefender
is a nuisance

Code: [Select]
   case IDM_Splash
           Splash()

Hello Charles

do you think that the use of the single global window handle hwnd would have make it
difficult for users to build multiple windows? 

since currently, if you close a  particular window, then all the windows would also be closed.

maybe you should make provision for multiple window handles in your winutil.inc and glwinutil.inc files
