Something can be done or not a fit? lblError.Caption = "The Start row must be a number!" endFlag = GeneratorRandomNumberNoDuplicates(typeRandom, minimum, maximum, decimalPlaces, i, arr) Else 'Generate decimal random numbers Dim arr() As Double Operation process steps, as shown in Figure 8: The "flag" defined at the beginning of the code is a global variable used to terminate the generation of random numbers; btnCancel_Click () is the execution event of the "Cancel" button; Sub btnClear_Click is the execution event of the "Clear" button; btnSubmit_Click () is the execution event of the "Submit" button . 3. End If For i = 0 To decimalPlaces - 1 lblProgressBar.Caption = i The "Start row and Start column" are both changed to 1, and "The number of Rows and The number of Columns" are changed to 4, enter 2 for the "Decimal places", click the "Submit", 16 random numbers with two decimal places are generated. endFlag = True & strMsg We then take the names off, number them 1-50 (Or however many entries there are) for example then generate 1 number at a time, crossing off the name drawn out then keep on drawing names out till everyone has been drawn. Click "Run", select "Run Sub/UseForm", open the "Generate Random Numbers" dialog box, and switch to the Excel window. If the upper bound is less than the lower bound, the array is empty, otherwise it is not empty; for example, the code "If UBound(arr)> LBound(arr) Then", the upper bound of the array "arr" is greater than its lower bound, so the "arr" is not empty. The "0 To totalCells-1" is the value range of elements of the dynamic array. Generating a list of random words . The fuction is to display the progress every 100 random numbers generated; the "i Mod 100" is used i and 100 to mod, that is, take the remainder. Click "Run", select "Run Sub/UseForm", open the "Generate Random Numbers" dialog box, and switch to the Excel window. Add button. If tbColumns.Text = "" Then lblProgressBar.Caption = i Exit Sub The RAND function takes no arguments. startColumn = CInt(tbStartColumn.Text) numRows = CLng(tbRows.Text) You can generate multiple rows and columns. Examples of frauds discovered because someone tried to mimic a random sequence. Determine whether the array is empty and take the length of the array. End If Enter "Number of Rows" 8 and "Number of Columns" 3, and click "Submit", Then generate 8 rows and 3 columns of random numbers; click "Cancel" to end the codes running; the operation process steps, as shown in Figure 4: A. Select the "Columns:", move the mouse to the right adjustment handle, after the mouse becomes a white double arrow, hold down the left button and drag to the right to make the text completely displayed.

If you want to generate no duplicate random numbers in batches in Excel, it is not easy to do it with formulas, but it is easy to do it with VBA. End If The final result of the formula Syntax of the RANDBETWEEN Formula temp = Rnd If Not IsNumeric(tbStartRow.Text) Then Dim numCols As Integer DoEvents & strMsg. decimalPlaces = CLng(tbDecimalPlaces.Text) Dennis, just as an aside, I noticed that your signature says you're using Excel XP Professional, but that's not really a version of Excel.
