You can verify this by launching Word the old-fashioned way and opening File1 at the bottom of the File menu after running the sample code.

Although it would be difficult to do an exhaustive test, in theory this should work from any Automation client-Visual Basic, Excel, Power Point, or any other.

I am filling a richtextbox via the Append Text method and it works great. There is not currently a way to do this built into the framework, but WM_SETREDRAW will do what you're looking for: [ Dll Import( "user32" ) ] private static extern bool Send Message( Int Ptr h Wnd, int msg, int w Param, int l Param ); private const int WM_SETREDRAW = 0x B; int paint Frozen; private bool Freeze Painting Hope this helps.

However, I would like to to off screen updating, add my 50 or so lines to the richtextbox, and then turn screen updating back on.

Application object and replace them with invisibility lines: Notice that you want to put the Word. Visible = True line in an error-handler or in a spot where you know it will be run if something goes awry. (If you do get stuck with an invisible Word in the middle of a crash, you can launch the Task Manager and kill the WINWORD.

Hi Dave, You can use WM_SETREDRAW message to do this.

This example demonstrates how turning off screen updating can make your code run faster.

The example hides every other column on Sheet1, while keeping track of the time it takes to do so.

The offering is not appropriate for situations that require urgent, real-time or phone-based interactions or complex project analysis and dump analysis issues.

Issues of this nature are best handled working with a dedicated Microsoft Support Engineer by contacting Microsoft Customer Support Services (CSS) at

property controls most display changes on the monitor while a procedure is running.

When screen updating is turned off, toolbars remain visible and Microsoft Word still allows the procedure to display or retrieve information using status bar prompts, input boxes, dialog boxes, and message boxes.

Word does not need to display itself in order to run.

In the above code, you could omit the lines that create and use the Word.

Many people write their own macros to manipulate the information in a workbook.

Many times the macro may do quite a bit with the data, such as selecting different cells, replacing values or formulas, and taking other types of actions.
