Recall - Null A Text Box
Feb 1, 2005
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,
Recall

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!

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 want to add a system of getting unique numbers into my database based on the month followed by a unique 3 digit code. For example, if it is February and this is the first record then the reference will read 02/001. Any ideas how I would go about doing this.
I've set up a seperate table called Reference numbers as these reference numbers will be used on any number of forms.
Cheers,

I've set up a DB to monitor employee hours. I have an employee table with a relationship to work done (one record = one days of work), so everyday is a new record in the work table. This is fine to monitor daily work patterns. However I need to calculate weekly work and other calculations (such as sixth and seventh shift payments, 15%payments, 25% payments etc). Is there any way that I can create a query that will give me one record for an employee that gives me start and end time for a Sunday, same for a Monday etc.
In other words I want to put start and end time for a Sunday to Saturday ( 7 records) into 1 record at the end of the week? (for each employee in the DB.
Any ideas?

How can I specify the list that appears in a combo box by programming it with VBA.
I have eight unbound text boxes on a form and I want a combobox to generate its drop down based on the values in these boxes.
I think I'd have to create 8 variables and take the values from these text boxes and assign to the variables. The bit I get stuck on is how to make these variables appear in the combo box list.
Please help,

I have a template fax set up in Microsoft word and want to be able to export fields from my database (in form view) to the word document. For example, I have a 'purchase order No' on the access form which I want to send to the Word document. When exported I then want the user to be prompted to save the document as a new name so they do not overwrite the original template fax.
Any ideas guys,
Cheers,

This is probably v. simple but is doin me head in.
I've got a form based on a query containing three figures (currency). I want a total box that will add the 3 up. On the query I've created a field called Total with the following:
Total:sum([Text1]+[Text2]+Text3])
When three figures are in it works fine. If one of the figures is not there it displays #Name. I could get the fields in the table to automatically display 0, but if a user deletes off the 0 I'm stuffed.
Where am I going wrong?

I've been reading a bit on the site from users who are working with DB over the network and speed issues it brings. I've got the same problem over a Citrix network with a split DB. The speed issue comes when loading up a bound form. I've rewritten some of the code so that when a user leaves a form, instead of closing down, it simple gets hidden and things have speeded up a lot. However, the initial load of the screen on DB start up is v.slow.
I'm interested in finding out how to use an unbound form ad then associate it with the data when it has loaded. Can anyone give me any tips or point me in the way of a sample DB.
Cheers,

I've created a linked table database which is running currently at my offices over a Citrix network. We want to put the database into 2 other sites (initially), however, the drive that all the sites see is slightly different for my site than the other sites (i.e. I see it as W: but they see it as P, but physically they are the same drive. Obviously, the links to the tables would have to be changed so the other FE could see the BE. I can't do this from my site as I cannot see the drive as they see it. I don't want them going into the FE design to update the linked table manager everytime I make changes and send them a new DB.
Does anyone know how (or have an example DB) to create a button on the FE that will ask the user to select the location of the BE with a file browser, for example and then update the table links.
Think this is a bit of a tough one, but I'm sure someone must have done it at some point.
Cheers,
