VB3 How to Play an .AVI Video File in Full Screen (104123)

MORE INFORMATION

The example uses the mciSendString application programming interface (API) from Microsoft Windows version 3.1 or Microsoft Windows version 3.0 with Multimedia Extensions.

For the example to work, your computer must be able to play .AVI files and you need either Microsoft Windows version 3.1 or Microsoft Windows version 3.0 with Multimedia Extensions.

The .AVI file included in the example (WNDSURF1.AVI) is the one from Microsoft Video for Windows.

Step-by-Step Example

1. Start Visual Basic or from the File menu, choose New Project (ALT, F, N) if Visual Basic is already running. Form1 is created by default.
2. Add a command button (Command1) to Form1, and set its caption property to: Play Video.
3. Add the following line of code to the (general) (declarations) section of Form1:

      ' Enter the following Declare statement on one, single line:
      Declare Function mciSendString Lib "mmsystem"
         (ByVal lpstrCommand$, ByVal lpstrReturnStr As Any,
         ByVal wReturnLen%, ByVal hCallBack%) As Long
   						

4. Add the following lines of code to the Command1 Click event procedure:

      Sub Command1_Click ()
         CmdStr$ = "play c:\winvideo\wndsurf1.avi fullscreen "
         ReturnVal& = mciSendString(CmdStr$, 0&, 0, 0&)
      End Sub
   						

5. From the Run menu, choose Start (ALT, R, S) to run the program. Click the Play Video button to watch the video full screen. The video will last for a few seconds and return back to the Visual Basic environment.
