Evaluate also enables you to get the results of a single-cell or multi-cell array formula passed to Evaluate as a string. Evaluate, for example as The difference between using Application. Public Function EVAL(the Input As Variant) As Variant ' ' if UDF evaluate the input string as though it was on this sheet ' else evaluate for activesheet ' Dim v Eval As Variant Application. If the input string resolves to an array formula then EVAL will return the corresponding array of results.
Volatile On Error Go To funcfail If not Is Empty(the Input) then If Type Of Application. EVAL must be volatile because Excel cannot detect which cells the input string argument refers to, and hence does not know when the function needs to be recalculated.
(I guess technically it will make it run faster since there will be no dialogs, but you know what I mean). This will speed up operations while also providing the user with a better and more tolerable experience. It will be specially usefull with those horrible macros made by the recorder, full of unnecessary "select" and "activate". I had a long-running macro several years ago that took almost a minute to run.
Use this code template as a starting point (the error handler ensures that these properties are turned back on at the end of the sub, even if it errors) Sub Your Sub() On Error Go To EH Application. Select Next i 'get results results = "Screen Updating not disabled: " & Format(Time - start Time, "hh:mm:ss") & " seconds" start Time = Time 'scenario 2 - screenupdating disabled Application.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.Apparently it calculates one more time after the cycle. Can anyone tell me if there is special calculation under Application.Calculation = xl Calculate Automatic for round formula? If you look at the formula bar, you can see that the formula itself is not inserted into cell A3. For example, place a command button on your worksheet and add the following code lines: As a result, your code will run much faster and you will only see the end result (10000).
Simply add the following code line to achieve this.
This page lists some suggestions and strategies for optimizing your Visual Basic For Applications (VBA) code, so that it will run faster.
There are few absolute rules for optimizing VBA; you'll see the best increases in performance by streamlining the basic logic.
You can use the Worksheet Function property in Excel VBA to access Excel functions. For example, place a command button on your worksheet and add the following code line: When you click the command button on the worksheet, Excel VBA calculates the average of the values in cell A1 and cell A2 and places the result into cell A3. You can manually recalculate the workbook by pressing F9. In most situations, you will set calculation to automatic again at the end of your code.
To insert the formula itself into cell A3, use the following code line: Sometimes you may find it useful to disable screen updating (to avoid flickering) while executing code. You can instruct Excel VBA not to display alerts while executing code. For example, place a command button on your worksheet and add the following code line: When you click the command button on the worksheet, Excel VBA closes your Excel file and asks you to save the changes you made. To instruct Excel VBA not to display this alert while executing code, update the code as follows. As a result, Excel recalculates the workbook automatically each time a value affecting a formula changes.
I have changed it slightly so it loops 10,000 times and I execute it 10 times for sample size.
