Text Box Value Is Null
Aug 16, 2007
I have a very simple question that I should now the answer to but I must be having a brain cramp.I have a text box on my form and I want to make sure the textbox is not null before running some code. How do I do that?
if Me.txtBatchID Is Null -I get an error 'Object Required'
If Me.txtBatchID = "" -doesn't work.Even if there's nothing in the text box, apparently access thinks it is.Can anyone help me with this? I can't believe I haven't been able to figure this one out!

I've got text box on a form that contains a text value. It is a bound form. I've put code behind the text box that runs on the 'Before Update' event to check if the figure already keyed is a duplicate. If it is then I want the text box to be cleared. I've got it to work if I use the me.undo code, but I only want the text box to be blanked and not the whole forms data. When I put in code txtAccNo = "" or txtAccNo = null then I get an error message telling me the form data cannot be saved using this method. In the table I've set this field up so AccNo is indexed and does allow duplicates, but then I check for duplicates actually on the form in question. It is not the primary key in the table. Any ideas what I can do just to blank this cell when a duplicate occurs?
Cheers,

Good Morning All,
I have an unbound text box on a form.
The Control Source references a text box on one of its subforms.
How do I make it return a 0 when the subform text box is null?
It seems like an if statement of some kind.
Thank you all in advance.

I have a date field in a form which is not compulsory.
I then pull this date field into a query to create a report.
If the date is not entered then is it possible for "Date not entered" to be written into the report automatically. I have tried playing around with nulls but have had no luck.

Hi,
i have created a query from just one table, which is basically a list of Financial transactions.
There is a field called supplier code, in this query.
Most of the transactions have a supplier code, but there are a few that don't.
i've got another table that has the supplier name against the supplier code.
i want to bring this table into the query, so that i can show the supplier names against those records in the query that have a supplier code.
when i add this table and link the 2 tables up and put the supplier name into the query. The query excludes the records with no supplier code.
This is presumably, because they contain null values.
I've been reading about the Nz function and i think this is what i need to use.
i've tried this, but it still only brings through the records with a supplier code and not all of them.
How i've done this is to go into the design mode of the query and in the column that would have null values i have click "build"
in here i have the following formula.
Nz([Supplier Name],"No")
Am i doing anything wrong?

Hi All,
I have a field called PRICE and obviously it is a NUMERIC field as it need to perform calculations such as calculating Total Quantity * Price etc. At the moment the PRICE is inputted manually by the User on a Form and when it has no Price it is simple left blank.
What I wish to include is that on the REPORT when the field is empty it writes the text FOC instead of leaving it empty.
Can you please anyone suggest a way of doing this.
Thanks any help will be much appreciated :o

Hi members,
I have two empty columns in my access database whose total width is supposed to be 385 chars (255+130). I am trying to find a way to be able to export this blank field with a total of 385 blank spaces onto an ASCII text file.
A sample row looks like this:
L ***** 385spaces needed here ***** 888888 EXAMPLE DEALER NAME 1234 EXAMPLE LANE EXAMPLE ADDRESS LINE 2 EXAMPLE CITY CA88888 80088812348008881234FORD JOE DEALER NAME 8008881234
After the first letter L in position 1, I need to have 385 blank spaces and then at 387th place I have some other data to follow.
I tried a lot to use the export wizard, but it doesn't help. Is there a way to do this?
I would really appreciate any help.
Thanks,

I am trying to use this expression in my textbox to show when the textbox value is null:
=IIf(IsNull([ContractStatus]),"Null",[ContractStatus])
It gives me a circular reference error (#error in the textbox). If I change it to this:
=IIf(IsNull([ContractStatus]),"Null","ContractStatus"), it will display the text "Contract Status" (obviously).
What am I overlooking here? Does this need to be done in VBA?

I am attempting to use VBA code to make the label in my report hidden if the text box is blank. I am very new to coding, and am not sure how I would express this in code. I have been looking at a few examples of how to get this done, but it doesn't seem to work. Where to insert the code. Attached is the image of the properties for my label and text box that I want hidden if text field is blank. I al just lost trying to figure this out.

On a form, I want to disable the save button, 'cmdSave' whilst the form's mandatory fields have been left blank.
I've put in a smart tag, called, 'Req' against each required field and have used the following code on the forms current event.
Code:
Private Sub Form_Current()
Dim ctl As Control
For Each ctl In Me.Controls
If ctl.ControlType = acTextBox Or ctl.ControlType = acComboBox Or ctl.ControlType = acListBox Then
[Code] ....
The save button is disabled, but it won't enable again after each field has data entered against it.
I also have this code in the AfterUpdate event in each required field:
Code:
Private Sub cboErrorID_AfterUpdate()
Call Form_Current
End Sub

I know you can't store text in a numeric field but I always thought you could store numbers in a text field - provided you didn't need to do any calculations on them. My problem is as follows:
I receive an Excel 2003 spreadsheet once a month, which I save to a specific filename/location overwriting the previous file. My Access 2003 database uses this as a linked table and (among other things) runs an append query to add the new data onto an existing table.
We have now added a new column called Reference in the spreadsheet. Often, this will be empty, but it could contain numbers or text. This is the first month I have received it and most entries are blank (including the first row) but further down there are some numeric values.
So I added a new Reference field to my main table and set it to text. Then I amended the append query to include the new field. But when I run it I get the error "Numeric field overflow". If I take that column back out of the query, it runs fine, so that's definitely the offending data. And when I open the linked table in Excel and scroll down to where I should see the reference numbers, I see #Num! So it looks to me like it doesn't recognise numbers as text.
Things I've already tried
In Excel, I formatted all the Reference cells as text.
That didn't work, so next I added a dummy record at the top of the Excel file (just under the headings), with zeroes in the numeric columns and 'X's in the text columns including Reference.
But that doesn't work either. Given the above circumstances, what's the best way to proceed with this?

Hi friends,
I am new to this forum, and I am facing a problem while learning MS-Access.
I am preparing a database that stores the marks obtained by students in a particular paper in addition to their particulars in tables.
A query is then generated to canculate the aggregate marks and result (Pass/Fail) for the student. It is then presented in a report fomatted as a marksheet, as well as one tabulation chart.
The database is very crude in format, but I am happy with it since I do not know programming at all, and still I could make it.
I have used in built menu of "ms-access" and mouse clicks only for generating query. It was a learn by doing method.
The problem is that my marksheets require absent students to be marked as "ABSENT" or something of that kind. If I convert my Null values to :
Expr2: IIf(IsNull([E_1]),"ABSENT",[E_1])
It shows ABSENT for null value, but refuses to make column total for E_1; On the other hand if I do not enter such expression, it makes column total in tabulation report, but fails to mark "ABSENT" to those who did not appear. So I have to lose one thing to gain another, while I need both.
Can anybody help me at this?

I 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

It might be an easy one but I just wasted the past hour deciphering through my code in order to solve the run-time error '94' that I'm getting when trying to execute the following code:
Code:

Hello all,
A bit of a weird one, I've got a query and the criteria for showing records is that one particular field is null. However the query is showing records with the values in the field chosen for the Is Null.
Not sure why this is happening, has anyone come across this problem before?
Thanks.

I think the title pretty much sums it up....
I have a query where data is first sorted by user input; first field's criteria: [fieldname], then by another field's criteria: Is Null.
I know there are records containing null values in the second field, as I have run a select query with the criteria: Like "*", to make sure they are null, and not zero-length-strings.
The query is refusing to return any results...
Any ideas?

In my form's text box I have noticed that I can;t write paragraphs ie use the TAB key to start a new line. If I use rich text I assume this will be possible. But are there any disadvantages to using rich text?

We need to move rich text from an Access memo field to a Word text box. So far the best Ive been able to come up with is in the code below. In this code pprs!What is a record set field of a table memo field that is bound to a text box enabled for rich text. The rich text seems to be stored as html as so I can get word to convert it by enclosing it in html tags.
Dim What As Word.Shape
Set What = doc.Shapes.AddTextbox(msoTextOrientationHorizontal , doc.PageSetup.LeftMargin, 225, 534, 0)
Dim sPath As String
sPath = "G:Temp.html"
Open sPath For Output As 1
Print #1, "<HTML>" & pprs!What & " </HTML>"
Close #1
What.TextFrame.TextRange.InsertFile (sPath)

I have a single field in a table called "Client Contact", where users enter a semicolon between the name, address, and city state & zip. My reason for this was so we could copy client info with a single copy and paste (like from an email). But, on the final report, it needs to have these three parts split up into different lines, or even different textboxes. I can't find a way to do that.

I have a column which contains "text digit text" as "AAA 222 BBB". The numbers of letters or digits can vary.
I need to SELECT the column which contains digits in a specific interval. For Example I have
"DFS 673 JKK"
"A 3454 LJLJ"
"SD 854 JKLJD"
I need to SELECT the column which contains 600 < Digit < 700 the result of the query in this case would be "DFS 673 JKK" because 673 is between 600 and 700.
Thanx for any clue or suggestion...
