Code Printer VB 6.0

As users begin to understand an application and use it to its full potential they often times need to print content for easier reading or permanent record. Fortunately Visual Basic 6 printing is not only easy but very advanced. One of the simplest ways to do printing is by using the PrintForm method which Visual Basic provides for us. This VB6 printing tutorial explains exactly what this method is and how you can use it in the applications you develop.
The PrintForm method sends an image of the current form to the default printer.
The sample application prints the image of the form shown below without the command buttons:


The code for this application is quite sparse (as it does not actually perform any calculations).

The Form_Load event contains code to center the form on the screen and to format the Date and Time labels:

Private Sub Form_Load()

'center the form:
Me.Top = (Screen.Height - Me.Height) / 2
Me.Left = (Screen.Width - Me.Width) / 2

'display date & time
lblDate.Caption = Format$(Date, "m/d/yyyy")
lblTime.Caption = Format$(Time, "h:nn AM/PM")

End Sub


The Click event for the Print button (cmdPrint_Click) hides the two command buttons (by setting their Visible properties to False), issues the PrintForm statement, then makes the buttons visible again:

Private Sub cmdPrint_Click()

cmdPrint.Visible = False
cmdExit.Visible = False
PrintForm
cmdPrint.Visible = True
cmdExit.Visible = True
End Sub

The Click event for the Exit button (cmdExit_Click) ends the program by issuing the End command.

Private Sub cmdExit_Click()
End
End Sub
