VBA Setting Variables To Nothing Or Null

Mar 6, 2012

I've been looking at code a lot here and at the end I always see people ending their VBA code by setting the variables to nothing. Why is this done? Don't all the variables in the sub automatically get trashed when the sub ends?

So what would be the difference of me doing:

Code:
Sub emailUser(strSubject As String, strMessage As String)
'Allows you to email the user if an error occurs instead of giving a messagebox
'and stopping everything. This way if something can not be checked out, you know
'what happened and can redo it the next morning (or fix the error if need be)

Dim olApp As Object 'Outlook.Application
Dim Msg As Object 'Outlook.MailItem

[Code] .....

vs

Code:
Sub emailUser(strSubject As String, strMessage As String)
'Allows you to email the user if an error occurs instead of giving a messagebox
'and stopping everything. This way if something can not be checked out, you know
'what happened and can redo it the next morning (or fix the error if need be)

Dim olApp As Object 'Outlook.Application
Dim Msg As Object 'Outlook.MailItem

[Code] ........

Setting Correct Variables?

Oct 24, 2013

I have put together the below macro to take data from an Excel spreadsheet and place in a word documents (using bookmarks.

What should happen is it should open up the correct word template depending on what data is in column E (Servicecode) and fill in the bookmarks with the data from excel.

It all works fine and goes through the loop and saves, inputting the correct data into the bookmarks but after looking at the saved templates and scrolling through using F8 the IF ELSE does not seem to work. It CALLS theBearSSR macro rather than the relevant macro e.g. word in E2 is Cele, the macro should call the CeleSSR macro (which opens the correct template).

I don't think i have declared my DIM Servicecode correctly... I can't seem to figure out how to make the IF ELSE condition look at the Servicecode and then go to the correct sub routine (the difference between them is the template that is opened).

HTML Code:
Sub Celebration()

Dim departuredate As String[code]......

Locating Important Columns In A Table Of Raw Data - Setting Variables Using A Loop

Feb 22, 2012

I need to be able to locate some important columns in a table of raw data (the column locations are not fixed).

I would like to identify the locations (based on the heading values in Row 1) and store them as Public variables. The Match function works fine for this, however I'd like to make a simple loop to set these variables (opposed to repeating the function for each).

In the example below, I can't figure out how to reference "List1(Count)" as the name of the variable I'm trying to set.

Code:

Public Field1 As Long, Field2 As Long, Field3 As Long 'The column numbers will be stored here
Sub FindFields()
Dim List1(3), List2(3)
Dim Count As Long
'Public variables (declared above)

[Code] ......

So after running FindFields(), the Test1() macro should give "1 - 2 - 3" (for example) as the locations of the fields in Sheet1. But currently this doesn't work.

Return Zero If Zero Else Null

Nov 1, 2012

I'm looking up values from a pivottable.

I have the pivottable options to show nothing if error.

If the pivottable has nothing showing for the quarter I would like the formula to return nothing.

It's currently returning '0%'

So I'm getting the following

Qrt1 = 88%
Qrt2 = 0%
Qrt3 = 0%
Qrt4 = 0%

Average = 22%

The answer I want is

Qrt1 = 88%
Qrt2 =
Qrt3 =
Qrt4 =

Average = 88%

In the pivottable the only quarter that has a value is Qrt1 (88%) - The others are blank

Since there is a chance I could have a qrt with 0% I can't just iqnore the zero when averaging. how to do this?

Here is my formula

Code:
=IFERROR(GETPIVOTDATA("HHCompl",DataSelection_units!$A$5,"fldEntity",$A$1,"fldUnit",$A39,"Quarter",B$38)," ")

How To Insert A NULL Value

Aug 8, 2008

When I insert a double quote ("") into a cell as a Null value this causes problems when creating formulas that use the cell.

I've searched many posts to do with Null values but can only find information on checking for a Null value, like ISBLANK().

But, I've not been able to find any information on how to write a formula like
=IF(ISBLANK(A1), "",A1/B1)
and substitute the double quote ("") with a value that is Truly Null?

Counting Cells That Are Not NULL

Aug 25, 2009

I have a large number of customers listed in an excel sheet that may recieve a visit from my organisation. The reason for the visit may vary and sometimes a customer may recieve more than one visit. Each Row (or record) maps to a customer. Each column has a visit type which I insert a date in to say when the customer has been visited.

I am looking for a function that will return if a customer has been visited or not. As dates can be summed like numbers I am currently saying in the "Visits Recieved" column =if(sum of dates (visit type colunm) >0, 1,0) Then I simply sum the column to get my answer of how many csutomers have been visited.

Inserting A Null Cell Using IF

May 28, 2007

I have a simple formula, =IF(A1=0,"",A1) to replace 0 with blank. However ISBLANK doesn't recognize the result as blank, because it's really testing for an empty / unused cell rather than a blank one.

Is there something I can replace the "" with so that ISBLANK returns true?

Ignore Null Data In A Sum

Jul 24, 2009

I have two sheets in my workbook: one holds data (Sheet2), the other processes the data (Sheet1). Sheet2 has temperature data for each hour of every day during the year 1997 - about 9000 rows. Sheet1 averages the temperatures for each day together, and therefore has only 365 rows.

However, some of the data is missing - null values are represented by the value -9999. Sheet1 only averages hourly data if there at least 22 non-null values. If there are fewer than 22 non-null values, a message is written into the cell to indicate such. (See day 119 on Sheet1 in the attached file for an example of this)

I have the formula worked out to this point; however, I'd like to add in one more constraint: if a day has 2 or fewer null values, I still would like to average the data, but omit the null values in the average. (See day 118 on Sheet1 in the attached file for an example of this). My formula so far:

Macro: Listbox Value Null

2) Uses that value to copy and paste other items into the same sheet.

The first part is working, the second part gives me a "Run-Time error '94': Invalid Use of Null" error on this line:

Using Null Value In Formula Created In VBA

Nov 1, 2011

I'm attempting to enter a formula into cells on a spreadsheet through a macro.

I want the formula to read:

=if(isblank(G1),"",month(G1))

but because this is being created within a macro it doesn't like the double quotations.

I can get it to display "0" but i want those cells to be NULL. Right now my only idea is to make an IF statement in the code that doesn't insert a formula in those instances, but I'd like to keep them all as formulas for later changes. Anyway around this dilemma?

Example Code (only a piece):

Code:

With Range("F1")
.Value = "=if(isblank(G1),,month(G1))"
.AutoFill Destination:=Range("F1:F" & lastrow)
End With

Check First 2 Cells Of The Last Row Is Null Or Not

Jan 19, 2009

In a column "V", when the user enter "Y", i need to copy the entire row to another sheet("Written-off"), its working fine.Sometimes the first 2 columns of that entire row where the user enter "Y" may be null, so using my code, copy first entire row where user put "Y" and paste to another sheet("Written-off"), then user also enter "Y" to wherever in "V" column, this time the entire row should overwrite the last row in the "Written-off" sheet.

I found the reason is first column of the last row was null, so when check the first cell, if it is empty then the next entire row should be copied that area.
Is there anyway to check first 2 cells of the last row in a sheet in null or not?

If Right(Left(ActiveCell.Address, 2), 1) = "V" Then
myColumn = "V"
If Intersect(Target, Columns(myColumn)) Is Nothing Then Exit Sub
On Error GoTo last
If UCase(Target.Value) = "Y" Then
Target.EntireRow.Copy Sheets("Written-Off").Range("A" & Rows.Count).End(xlUp)(2)
Application.CutCopyMode = False
Sheets(Sh.Name).Select
Else
Exit Sub

Search Cells For Non Null Value

Nov 9, 2006

I'm having a problem with a seemingly simple formula I can't quite figure out. I need to search through four cells, M(n)-P(n), to find out if they have a value in each cell respectably. When the values are found I need them to form a make shift column in which the three cells underneath the cell with the formula are filled with any available values.

For example:
John Smith has the values: 1 in col M, 2 in col N, 3 in col O, and 4 in col P. That is of course ideal and I would be able to fill in the other cells very easy. But in my case John Smith has values: 1 in N, and 2 in P. Or whatever other order you can think of. I wrote a formula that looks like this:

=IF((M2="")*(N2="")*(O2=""),P2,(IF((M2="")*(N2=""),O2,(IF((M2=""),N2,M2)))))

This seems to work if they have a value in column M, but if for instance they dont but have a value in column N instead, it doesn't produce a result. Could someone give me some advice to what I am doing wrong? I am still new at writing formulas, so I'm sure there has to be some function I don't know about that would make this a lot easier.

0 As Valid Value Rather Than Null Or Empty

Apr 3, 2007

I am trying to define some variables as byte, but I want 0 to be a valid value rather than null. When there is no data, that is when I would like for the variable to be null.

Is there a way to accomplish this? In addition, I use the same variables in a loop, which are reset at the beginning of the loop. Is there a way to reset a variable without giving it a value (like 0)?

Summary Of Data Without Zero / Null

Mar 4, 2008

eg.: productlist + order amount + sum

Sheet: Masterdata
Column A: Productname
Column B: Product price
Column C: Product quantity
Column D: Total (=B*C 'obviously)

Sheet: Summary = All rows of Masterdata WHERE Product quantity Is Not Null (<>0) starting from row 5 in the summary sheet. note that if a value in quantity has been reset in the Masterdata, the Summary has to be updated. I do not want to use an advanced filter because the whole workbook needs to act like a portable template for various users which once in a while gets updated using external connection with a ms access database. ( Import of access report). I have no idea whether a copy function or customized pivottable (does not works because too much data), ... would do the trick.
