FIX: Accessing Image Property of PictureBox Diminishes Resources

MORE INFORMATION

The following shows you how to create a sample project that demonstrates this bug. The instructions assume that you have the System Resource Meter running so you can see the effect of accessing the Image property. The System Resource Meter is a system tool usually installed in the Accessories program group if you select the System Resource Meter option when you install Windows 95 or Windows 98.

Steps to Reproduce Behavior

1. Start a new Standard EXE project in Visual Basic. Form1 is created by default.
2. Add a PictureBox, Command Button, and Label control to Form1.
3. Set the Picture property of the PictureBox control to an appropriate bitmap file.
4. Copy the following code to the Code window of Form1:

         Option Explicit
         Private Sub Command1_Click()
            Dim I as Integer
            For I = 1 to 100
               Picture1.Picture = Picture1.Image
               Label1.Caption = Trim(Str(I))
               DoEvents
            Next I
         End Sub
   
   					

5. Press the F5 key to run the program. Minimize the Visual Basic IDE so you can see both Form1 and the System Resource meter running. Click Command1 and note that the GDI and System Resources diminish by about 20 percent with the click of the CommandButton.
