While I’m thinking about this stuff, I’d like to share a few simple tips for speeding up your Excel VBA code. So feel free to comment and share any other performance tips you may have.
Each time a cell that affects any formula in your spreadsheet is changed or manipulated, Excel recalculates the entire worksheet.
Screen Updating = False If my Debug = False Then On Error Go To Error Handler I'm afraid that's pretty much it. Screen Updating End Sub As I step through the code when I hove over Application.screen Updating it always says True. Then put it in debug mode and step through with screen updating turned off again, you should find that you still see the numbers going in one by one.
Then comment out the line which turns off screen updating and see what happens; you should find that you scroll down the sheet as the numbers get filled.
And after all don’t turn screen updating on/off many times in some loop. And one more note (which you probably don’t want to hear) if you want it quick use C .
A VBA add-in to quickly insert any of the sample code found on our site directly into the Visual Basic Editor, save your own frequently used code, and more!
Screen Updating = False 'swap between sheets 1/2 (need both sheets or this will crash) For i = 1 To numb Switches Sheets(1 (i Mod 2)). Screen Updating = True 'get results for part two results = results & vb Cr Lf & "Screen Updating IS disabled: " & Format(Time - start Time, "hh:mm:ss") & " seconds" 'show results Msg Box results End Sub Firstly I've been using the script written by Richie (UK) Post #7 Here It simply iterates through a loop changing the value of i in one cell., 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.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.
