Inserting date

[stanco]

Hi, I know there are a lot of discussion on inserting static date using vba, but I need something different. i need one that would insert a dummy date whenever the next cell is empty.

to be more specific, I need a code to reflect the date of the respective surveys in the respective column whenever i input the result, but will display a dummy date when the result is blank. (the surveys are done on ad hoc basis, so some people might have done 3, but some have not even started on it).

I intend to use pivot table to count the number of the survey done over time, so i can't leave any blank in the survey date column.

Name	Survey 1 Date	Result	Survey 2 Date	Result	Survey Date 3	Result

appreciate it if anyone can assist or suggest something for me please.

    Set rng = Range("A2", Range("A" & Rows.Count).End(xlUp))
    For Col = 2 To 6 Step 2
        On Error Resume Next
        rng.Offset(, Col - 1).SpecialCells(xlCellTypeBlanks) = DateSerial(1999, 12, 31)
        On Error GoTo 0
    Next Col
End Sub

The above put a date in the column whenever the date is blank

Having read your post again, I think you want date put in if adjacent RESULT column is blank

Sub AddDummyDate()
    Dim rng As Range, Col As Long
    Set rng = Range("A2", Range("A" & Rows.Count).End(xlUp))
    For Col = 2 To 6 Step 2
        On Error Resume Next
        rng.Offset(, Col).SpecialCells(xlCellTypeBlanks).Offset(, -1) = DateSerial(1999, 12, 31)
        On Error GoTo 0
    Next Col
End Sub

But this does not ensure that there is a date in every cell

 

[Yongle]

If you want BOTH the Date and Result to be blank before amending (eg to prevent a previously entered date being overwritten)

Sub AddDummyDate()
    Dim rng As Range, rng1 As Range, rng2 As Range, Col As Long
    Set rng = Range("A2", Range("A" & Rows.Count).End(xlUp))
    For Col = 2 To 6 Step 2
        On Error Resume Next
        Set rng1 = rng.Offset(, Col).SpecialCells(xlCellTypeBlanks).Offset(, -1)
        Set rng2 = rng.Offset(, Col - 1).SpecialCells(xlCellTypeBlanks)
        Intersect(rng1, rng2) = DateSerial(1999, 12, 31)
        On Error GoTo 0
    Next Col
End Sub

This would not add a date if Result contains text but Date is empty

Finally

You may want to add default dates automatcally whenever a new record is added in column A

Place this in SHEET module
(right-click on sheet tab \ View Code \ paste code below into code window \ {ALT}{F11} to go back to Excel)

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim offS As Long
    If Target.Row < 2 Then Exit Sub   [COLOR=#006400][I]'to ignore headers in row 1[/I][/COLOR]
    If Not Intersect(Range("A:A"), Target) Is Nothing Then
        For offS = 1 To 5 Step 2
                Target.Offset(, offS) = DateSerial(1999, 12, 31)
        Next
    End If
End Sub

Hi Yongle, thank you very much for the codes. I will try it out over the weekends.

On the topic of date, I do not know if this is possible, but let say i have to prepare a token to those who have done two or more surveys. but because there are thousands of rows (i know i can do a filter but i need to do this quite often and i am hoping to make it more "automatic").

Is it possible to extract the entire row from the table out to a fresh sheet whenever i input the start and end date?

taking your table for example (which i have amended slightly), my start date = 10/03/2019 and end date = 18/03/2019

The original table

	A	B	C	D	E	F	G
1​	Name	Survey 2 Date	Result	Survey 3 Date	Result	Survey 4 Date	Result
2​	Name01	04/03/2019​	123	09/03/2019​	124	11/03/2019​	125
3​	Name02	05/03/2019​	130	10/03/2019​	129	12/03/2019​	128
4​	Name03	06/03/2019​	107	11/03/2019​	123	31/12/1999​
5​	Name04	07/03/2019​	125	1/02/2019​		18/03/2019​	122
6​	Name05	08/03/2019​	164	31/12/1999​		31/12/1999​
7​	Name06	09/03/2019​	125	31/12/1999​		31/12/1999​

</tbody>

Results should shows on a fresh sheet
Start Date:10/03/2019
End Date: 18/03/2019

	A	B	C	D	E	F	G
1​	Name	Survey 2 Date	Result	Survey 3 Date	Result	Survey 4 Date	Result
2​	Name01	​		​		11/03/2019​	125
3​	Name02	​		10/03/2019​	129	12/03/2019​	128
4​	Name03	​		11/03/2019​	123	​
5​	Name04	​		​		18/03/2019​	122

I am away for several days so cannot help now.

But my immediate reaction would be to use Advanced Filter, which can cope with the filtering requirements and can filter results to another sheet
And it could easily be automated with a simple macro

Have a look at this https://www.contextures.com/xladvfilter01.html

Set up criteria range looking similar to this

Excel 2016 (Windows) 32 bit

	G​	H​	I​	J​	K​	L​	M​	N​
1​			Survey 2 Date	Survey 2 Date	Survey 3 Date	Survey 3 Date	Survey 4 Date	Survey 4 Date
2​	From	10/03/2019​	>=10/03/2019	<=18/03/2019
3​	To	18/03/2019​			>=10/03/2019	<=18/03/2019
4​							>=10/03/2019	<=18/03/2019

Sheet: Sheet1

This a totally different question from what the title suggests - probably best if you start a new thread to get the help you want.
