FIX: X / Y Coordinates Reversed Using PSet on Printer Object

• Microsoft Visual Basic Standard, Professional, and Enterprise Editions, 16-bit and 32-bit, for Windows, version 4.0

SYMPTOMS

If the PSet method is invoked for the Printer object, the X and Y coordinates are reversed: the first argument represents the vertical coordinate and the second argument represents the horizontal coordinate.

RESOLUTION

Invoke the coordinates in reverse order when the PSet method is used for the Printer object.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been fixed in Visual Basic 5.0.

Steps to Reproduce Problem

1. Start a new project in Visual Basic. Form1 is created by default. In the Click event of Form1, place the following code:

   
         Private Sub Form_Click()
            Dim I As Integer
   
         'Should print a horizontal dotted line
   
             For I = 0 To Printer.ScaleWidth Step 100
   
             Printer.PSet (I, (Printer.ScaleHeight \ 2))
   
             Next
   
   
         Printer.EndDoc
         End Sub 




2. Run the project by pressing F5. Click on the Form, and it prints out a dotted line to the default printer. The line runs across the paper. Since the default is portrait, the line runs along the short side of the paper. However, the print job contains a line that runs along the vertical axis.
   
   To correct the code above, the order of the arguments to the PSet method can be swapped:

   
         Printer.PSet ((Printer.ScaleHeight \ 2), I) 

   This should only be done when the PSet is used with the Printer object.
