SUMMARY
This article describes two different methods for printing a PowerPoint presentation file using a Microsoft Excel macro. The two methods differ in the way they handle the possible occurrence of OLE Automation Error 440, an error that occurs when an OLE Automation server times out or is not ready to accept a particular command.



MORE INFORMATION
The "quick fix" (Example 1) incorporates a small DoEvents loop which allows the server application to catch up. The length of the loop varies on a system by system basis, and depends upon the load currently on your machine as well. An alternative solution is to trap the error (Example 2). Once no error is returned, the program continues. This only happens when the .Print method is successful.

Example 1: Using a For/Next loop
Sub ppttest2 Dim pptApp As Object Dim waitForIt As Integer

Set pptApp = CreateObject("PowerPoint.Application") pptApp.Visible = True With pptApp.Presentations.Open("D:\MYPPTFILE.PPT ") For waitForIt = 0 To 1000 DoEvents Next With .PrintOptions .Print End With End With pptApp.Quit End Sub

Example 2: Using error trapping
Sub ppttest2 On Error Resume Next Dim pptApp As Object

Set pptApp = CreateObject("PowerPoint.Application") pptApp.Visible = True With pptApp.Presentations.Open("D:\MYPPTFILE.PPT") With .PrintOptions Do               Err = 0 DoEvents .Print Loop Until Err = 0 End With End With pptApp.Quit End Sub Microsoft provides examples of Visual Basic for Applications procedures for illustration only, without warranty either expressed or implied, including, but not limited to the implied warranties of merchantability and/or fitness for a particular purpose.
