DOCUMENT:Q221780 11-SEP-2001 [vbwin] TITLE :PRB: Printer Properties Show Incorrect Values PRODUCT :Microsoft Visual Basic for Windows PROD/VER::4.0,5.0,6.0 OPER/SYS: KEYWORDS:kbprint kbPrinting kbVBp kbVBp400 kbVBp500 kbVBp600 kbGrpDSVB kbDSupport ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual Basic Learning Edition for Windows, versions 5.0, 6.0 - Microsoft Visual Basic Professional Edition for Windows, versions 4.0, 5.0, 6.0 - Microsoft Visual Basic Enterprise Edition for Windows, versions 4.0, 5.0, 6.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When you read a printer property, such as Mycopies = Printer.Copies, before you print anything, the results are incorrect. Specifically, the values that are returned do not match what you see when you examine the printer's properties directly. CAUSE ===== This behavior occurs because the printer object is not initialized. MORE INFORMATION ================ Steps to Reproduce Behavior --------------------------- 1. Start a new Standard EXE project. Form1 is created by default. 2. Add a CommandButton, a ComboBox, and four TextBox controls to Form1. 3. In the code window of Form1, paste the following code: Option Explicit Dim MyX As Printer Private Sub Combo1_Click() For Each MyX In Printers If MyX.DeviceName = Combo1.Text Then Set Printer = MyX Exit For End If Next Text1.Text = Printer.Copies Text2.Text = Printer.DeviceName Text3.Text = Printer.Orientation 'Text4.Text = Printer.CurrentX End Sub Private Sub Command1_Click() Unload Me End Sub Private Sub Form_Load() Dim x As Integer For x = 0 To Printers.Count - 1 Combo1.AddItem Printers(x).DeviceName Next x Combo1.Text = Printer.DeviceName Text1.Text = Printer.Copies Text2.Text = Printer.DeviceName Text3.Text = Printer.Orientation 'Text4.Text = Printer.CurrentX End Sub 4. Make sure that you have more than one printer installed on the computer, and that the default number of copies and orientation are different for both printers. 5. Save and run the project. When you change selections with Combo1, the value in Text2 changes, but Text1 and Text3 do not change and are therefore incorrect. Text4 is not being used yet. 6. Click Command1 to stop the project. WORKAROUND ---------- 1. Under Combo1_Click and Form1_Load in the preceding code, uncomment the lines that read "Text4.Text = Printer.CurrentX". 2. Save and run the project again. When you change selections with Combo1, the values for the first three TextBoxes change to the correct values. Text4 simply receives the same value each time.
