The information in this article applies to:

  • Microsoft Windows CE Toolkit for Visual Basic 6.0
  • Microsoft eMbedded Visual C++, Version:4.0
This article was previously published under Q235386

SUMMARY

The Beep statement is not available in eVB/VBCE applications. However, the Beep functionality can be implemented using the MessageBeep API call.

MORE INFORMATION

VBCE 6.0 includes the capability to declare and use certain system application programming interfaces (APIs). The file WINCEAPI.TXT is provided with the VBCE Toolkit and includes sample declare statements, constants, and other useful information.

The following code demonstrates this sample:
  1. Create a new Windows CE project in either Visual Basic or eMbedded Visual Basic. Form1 is created by default.
  2. Place a Command Button on Form1.
  3. Paste the following code into the code module of Form1:
    Option Explicit
   Declare Function MessageBeep Lib "Coredll" (ByVal wType As Long) As Long
   Const MB_ICONHAND = 16
   Const MB_ICONQUESTION = 32
   Const MB_ICONEXCLAMATION = 48
   Const MB_ICONASTERISK = 64
   Const MB_ICONINFORMATION = 64   'MB_ICONASTERISK
   Const MB_ICONSTOP = 16 	        'MB_ICONHAND

   Private Sub Command1_Click()
      Dim ret
      ret = MessageBeep(MB_ICONEXCLAMATION)
      If ret = 0 Then Msgbox "Error occurred"
   End Sub
