This is the function i'm using for summing a listbox column:
Function TonSum() As Variant
Dim I As Integer, J As Integer, ctl As Control
Set ctl = Me.lstDrivera2
J = ctl.ListCount - 1
[code]...
The problem i have is if one the records in the listbox doesn't have a value (is null) then Access gives me a 'Type Mismatch' error. How to treat the null value so it excludes it from the sum?
I have a report based on a table. In the report I sum the columns. In a textbox ControlSource I use "=Sum([ColumnTotal])" and it works. Some of these numbers are zeros. I would like to exclude the zeros in the total. How do I do that?
View 5 Replies View RelatedI have a multi-select listbox (called PotentialItems) which behaves perfectly unless one of the fields has a null value in it, in which case I get an error 13, "Type mismatch" in the following code. It is valid business-wise for column 9 to be null.
Code:
Dim varItem As Variant
Dim dblTargetPrice As Double
With Me.PotentialItems
For Each varItem In .ItemsSelected
If Not IsNull(varItem) Then
dblTargetPrice = Nz(.Column(9, varItem), 0) '<----- Error here
End If
Next
End With
I was wondering if a list box can be made so the header of each columns is clickable.. so you can sort by that column either alphabetically or numerically?
View 1 Replies View RelatedIn short, I have a form that has a combo box containing people type values. Then two text entry boxes, firstname, lastname. Then an add, update, and delete button...
When the person type is chosen from the cbo, and the names are filled out, and the 'add' button pressed a query sends the values back via sql insert, and a listbox next to these controls then lists the new person records. Great - No worries...
Then, when someone wants to update the record now shown in the listbox, on double click of the record in the listbox, vba repopulates the name text boxes from the listbox's columns values (easy), and then *magically* the person type combo box chooses amongst its values the value stored in the person type column from the listbox.
I can't get the combo box to be set to the value that I am grabbing from the listbox's column values.
Code:
cboContactInfoType.{magic happens here} = ListBoxOfficeContactInfo.Column(3)
txtContactInfoValue = ListBoxOfficeContactInfo.Column(4)
txtContactInfoValue2 = ListBoxOfficeContactInfo.Column(5)
Part of me wonders if I would have to program in a way to search among the combo boxes values and find out which one was selected from the listbox, find it's index value and then set the combo box to be that index/value record... but that seems like a hard way to do it... and I'm not exactly sure how?
How to do this? Or maybe change its color to white.
View 4 Replies View Relatedim trying to autosize list box columns depending on the size of the largest field in the column?
View 1 Replies View RelatedI saw the following code on the forums...
Dim i As Integer, c As String
With Me.ListBox.Column(0)
For i = 0 To Me.ListBox.ListCount - 1
c = c & Me.ListBox.ItemData(i) & ", "
Next
End With
c = Left(c, Len(c) - 2)
This works great!! Now I am trying to concatenate the column 3 of the listbox.
Tried to use the code below (pointing to the second column) but it always returns the first column data.
'Dim i As Integer, d As String
With Me.ListBox.Column(2)
For i = 0 To Me.ListBox.ListCount - 1
d = d & Me.ListBox.ItemData(i) & ", "
Next
End With
d = Left(d, Len(d) - 2)
ItemData does not allow pointing to my 3 column of the listbox.
I've been trying to populate a field in a form with information, but only if the field is blank.
What I am trying to do is this.
I have a continuous form displaying all of our principals, however when our principals are on leave I want to populate the field with the "acting principal". I have set it up so the field grabs the acting principal first but it is blank for several schools. For these schools where there there is no "acting principal" I want it to grab the substantive principal automatically and populate the field.
I have tried Is Null, Is Not Null, NZ, IF, Where and Then statements but to no avail.
I have a query and one of the fields is numbers. When I run the query I would like for that column to total the numbers. How can I do this and the have the total appear in the Query?
View 1 Replies View RelatedI do not understand what is happening here. I have foll0wing line in a calculated query field:
m: Switch([EmpID]<5,1) ' run Query 18 in attached example, A2007/2010
this produces 1 for all EmpID<5 and Null for all other EmpID's. All as expected.
But if I do this:
m: Switch([EmpID]<5,1,[EmpID]>=5,Null) ' run Query 19 in attached example
then the entire column is set to Null

How (in VB) do you "check" to see if the user has selected an item from a listbox? I've searched the forums and tried everything I know and I keep getting: "Invalid Use of Null"
Any Ideas?
I have a sales form. The sales form has many Call, Meetings and Emails linked to each sales record. I want to total all the number of calls, meeting and email records related to the sales record to give a total- Touches.I've created 3 queries;
1 - Counts Calls
2 - Counts Emails
3 - Counts Meetings
These all work fine however when I combine them to attempt to count the results it doesn't produce the correct results.I have a second query as well (no pun intended).
I am trying to sum together a column that has values in Time. The results displays as a decimal. How can I have the result display as a Time i.e. 1:20 (1 hour 20 minutes).
Hi!
I want to be able to filter a form based on a dropdown box, where one of the items can be null. (The field is of type short date).
the dropdown box is named "Fltr1".
The form is based on a query, and i have tried to express the filter in the query like this (sql syntax):
([Tablename].[Columnname]) Like "*" & [Forms]![frmMyForm]![Fltr1])
But this way, the records with this column being null are omitted...
I very much appreciate any help that leads me in the right direction ;)
thanks
Okay so I have a column called 'totalincome' on TblCashflow. There are 60 records of TotalIncome (represents 5 years or 60 months) per asset that I have on another table, TblLoanGeneral.
What I need to return is the LAST value from totalincome that is not null. For example, we may only have entries in the 60 records that go to row #35, or 50 or whatever. When I use the Last criteria it gives me the 60th record (in example would give me a 0), and when I use the Max criteria, it gives me the largest income value regardless of location(would be 50,000 in example). What I need is really where the "last" income amt is >1 (20) however, when you set last, it only considers row 60.In the example below I would want 20 to be returned.

I'm still a little new to this, so please bear with me. I've searched to no avail for what I am looking for, so if there is an existing thread and you would rather point me in it's direction as opposed to answering my question, that would be fine.
I want one of the parameters of my delete query to be only the first column of my "ProdList" listbox, but don't know how to specify this. This is what my query looks like so far... Can someone tell me how do i need to change it?
DELETE ProductionLog.Username, ProductionLog.Date, ProductionLog.OrderNumber
FROM ProductionLog
WHERE (((ProductionLog.Username)=fOSUserName()) AND ((ProductionLog.Date)=[Forms]![Production]![TheDate]) AND ((ProductionLog.OrderNumber)=[Forms]![Production]![ProdList]));
I have 1 query that connects 4 of my tables through a tracking number. I am trying to make it so the value (DStatus) from DTable will populate where a (DStatus) is provided, but where there is no (DStatus) the column is filled in with a (SStatus) from STable. There is always a SStatus for each tracking number, but not always a DStatus, where there is a DStatus, it is more accurate.
Can I do this all in 1 query, whether I have to make a new column within my query for this to work, whether I need to have my query output into a table first.
Is there something I could type into the Criteria field of my query.
I have tried using Nz([DStatus],[SStatus]), an Iif Statement, the IsNull function, etc with no avail.

hello all,
I was wondering whether there is an "easy" way to make the column widths of a list box to adjust to the largest peice of data under it.... without filling it in yourself in the design view... So in VB....
I know that there is the property COLUMNWIDTHS, and that you can adjust it by calling that property..
But how to make it the column width to adjust automatically to the largest piece of text in that column??
Any ideas would be welcome...
tnx

I have a list box with 3 columns and one line on my form and am writing an update query that is to use the value from the first column of the query to update a record in a table. I have referenced the list box as ListBox.Column(0) but the code displays a value of null when I run it and the record that is to be updated is updated to Null (it is blank). How do I write the code so that the value that is in column 0 of this list box is passed through the code?

Hi
I've created a listbox and am using the following code
