Vba prevent screen updating
, Excel and VBA expert Curt Frye introduces object-oriented programming and shows how to automate routine tasks and provide custom functionality to enhance Excel performance and efficiency.
This course introduces the Visual Basic for Applications programming language, covers creating subroutines and functions to hold code, and provides a solid grounding in the Excel 2007 object model.
While Excel will set this back to True whenever focus is passed back to Excel (your macro finishes) in most cases, it pays to play it safe and include the code at the end.
From my own test I find out that turning screen updating off and on takes about 15ms (tested in C# via Excel Interop).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.It also means that we cannot tell the macro recorder to not record our steps of selecting cells, sheets and scrolling around, even though the selecting of cells, sheets and scrolling is not needed in true VBA code.As a result, of all this selecting and scrolling, the screen flickers whenever your recorded macro is played back. Screen Updating Those that are familiar with VBA code may also be aware of the term Application. Unfortunately those that really need to know about this term (those that can only record macros) are often not aware of it.
