SUMMARYThis 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 INFORMATIONThe "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
Example 2: Using error trapping
