Class: Hourglass in Category Microsoft Visual Basic 6 : Application Techniques from Total Visual SourceBook

Wrapper class that implements an alternative way to show an hourglass in VB6.

One of the problems that can arise when using an hourglass is not setting the cursor back to the default. This class avoids that problem by automatically setting the cursor back to the default when it terminates.

Procedure List

Procedure Name	Type	Description
(Declarations)	Declarations	Declarations and private variables for the CHourglass class.
Value	Property	Get whether the cursor is an hourglass.
Class_Terminate	Terminate	Reset the cursor to the default.

Example Code for Using Class: Hourglass

' Example of CHourglass
'
' To try this example, do the following:
' 1. Create a new form
' 2. Add a command button named 'cmdTest'
' 3. Paste all the code from this example to the new form's module
' 4. Run the form

Private Sub cmdTest_Click()

  Dim dblStart As Double
  Dim clsHourglass As CHourglass

  Set clsHourglass = New CHourglass

  clsHourglass.Value = True

  ' Simulate a long operation by looping for 2 seconds
  dblStart = Timer

  Do Until dblStart + 2 < Timer
    DoEvents
  Loop

  MsgBox "Done!"

  ' You may either explicitly set the value to false, or just wait for the variable to go out of scope,
  ' in which case the hourglass is automatically turned off
  clsHourglass.Value = False

End Sub
