I have a Form where I Enter CustomerID in a combo box. This box has Two Columns CustomerID and CustName.
the CustName and CustFather reside in another query.
is there a way to show the CustName and CustFather everytime i enter CustomerID in the form?
The CustomerID is entered in a form and not in the same table as CustName and CustFather.
Tried DLookup but it just looks only the first time and then shows that same value everytime i open the form or update it. the dlookup is shown as:
=DLookUp("CustName","qryForRecovery","CustomerID =" & "CustomerID")
is there a way i can show the CustName everytime i update the CustomerID field?
This is the link to the snapshot of my recovery form.

Use a combo box to enter the customerId.
Then create a text box for the customerName, that links to the customerId combo, as explained here.
The trick is to properly set the properties of the combo:
RowSource Type: Table/Query
Source: SELECT CustomerID, CompanyName FROM tblCustomers
Bound column: 1
Column count: 2
Limit to List: Yes
Column widths: 3;0 'second column will be hidden
You don't need Dlookups or whatever ..just correctly designed ComboBox
RowSource = SELECT CustomerID,CustName CustFath From Customers
Bound column: 1
Column count: 3
Column width : 0;4;4
You won't see the ID ..but Customer Name will be nicely displayed.

I have an unbound text box [txt_AmendmentOF] on a form to count the total number of Amendments a specific record has in the database. So the user knows which amendment they are on. Just a simple you are on Amendment 3 out of 8. i have this calculation i am using in the Control Source field of the text box [txt_AmendmentOF]:
=IIf(IsNull([txt_Amendment]),0,Count([MIPR_Number]))
there is a Field on my table called [Amendment] its text box on the form is called [txt_Amendment]. I have the calculation return a zero in [txt_AmendmentOF] if [txt_Amendment] is null. I need it to count the record number [MIPR_Number] that are the same and return the total number of Amendments count in the [txt_AmendmentOF] text box. on my table i have private key field called [ID] it is an autonumber format. The problem with the code above is it is counting all the fields that have a [MIPR_Number] and returning the total row count of that. i am not an expert here so any help would be greatly appreciated.
Update to post..
I have also tried this and got an error in the text box
=IIf(IsNull([txt_Amendment]),0,Count([MIPR_Number]=[txt_MIPR_Number]))
Counting by a condition is one of the basic dataabase tasks. To get answers from a db, you have to query the database (and that is done by createing a query).
To count same[MIPR_Number]you have to group the data (a group contains same numbers), then count.
SELECT COUNT(id) as CountOfSameNr, [MIPR_Number] FROM Table GROUP BY [MIPR_Number]
Store this query as e.g CountMIPRNumber.
Now you have two options:
Use a Dlookup to get one value
=IIf(IsNull([txt_Amendment]),0,Dlookup("CountOfSameNr","CountMIPRNumber","[MIPR_Number] = " & [MIPR_Number]))
or add the query to form recordsource (join on [MIPR_Number], "SELECT * FROM TABLE" is forms query)
SELECT CountMIPRNumber.CountOfSameNr, TABLE.* FROM TABLE LEFT JOIN CountMIPRNumber ON TABLE.[MIPR_Number] = CountMIPRNumber.[MIPR_Number]
and reference the count field
=IIf(IsNull([txt_Amendment]),0,[CountOfSameNr])
I actually have a Access database where i have a table called "tblfreight" and two column is there (items and Price)
And I want to auto show the Price when I choose Items.
There is two Textbox: "txtitems" and "txtprice"
I want to be like this....
If txtitems.text = select from tblfreight and column items Then
txtprice.text = select from tblfreight and column Price
Else txtprice.text=0 (Zero)
You need to query your DB first..
Select * from tblfreight - will get you your data you need.
Then you need to put this data somewhere. You can use a combobox for this. Once you have your combobox filled with your data you then can set the price into a label or textbox easily.
You can use the combobox selected index changed event...
Inside the changed event something like this would work...
textprice.text = Combobox.selecteditem.value
This will give you a great start, that's why this answer just gives you the steps and not the full code.
I have a contact form and one of the fields in a the form is a Contact_Type_ID. This field is a number field which also corresponds to a text field in another table (e.g. 1 = expatriate).
When I cycle through the contacts, their Contact_Type_ID is 1, 2, 3... instead of Non-profit, CEO, Vice-president, etc. This is a problem because one has no idea what number 3 means.
I would like to a combobox that only displays the corresponding text.
I can't get the two columns and 0;1 format to work. My hunch is that it's because I'm drawing information from two different tables. I can generate the correct list, but then the main entry doesn't change as I cycle through the contacts to reflect the current contact's [Contact_Type_ID].
I can't edit any of the current tables because I am supposed to apply this application to a much larger scale database.
I also tried setting the SQL for the row source:
'Populate the connection combo box '
Dim typeSQL As String
typeSQL = "SELECT DISTINCT Contacts.[ContactTypeID], Contact_Types.[ContactType] " & _
"FROM Contacts, Contact_Types " & _
"ORDER BY Contact_Types.[ContactType];"
Me.cbo_ContactType.RowSource = typeSQL
However, I then have the same problem: the combobox won't update as I cycle through the contacts. I don't understand the difference between the rowsource and the controlsource. I feel that this distinction might be key here.
Assuming I understand correctly:
In the combo box properties, go to the Data tab.
Set the Control Source to Contact_Type_ID.
This means that when you go through the records, the combo box will correspond to the Contact_Type_ID field from your data.
Set the Row Source to "SELECT Contacts.[ContactTypeID], Contact_Types.[ContactType] FROM Contacts, Contact_Types ORDER BY Contact_Types.[ContactType];"
The Row Source indicates the data that the combo box has access to, which will help it determine how to display the control source value.
Set the Bound Column to 1
Set Limit to List to Yes
Now in the Format tab. Change Column Count to 2.
Next set the column widths to the 0;1 you mentioned in your question.
Now try looking at form view, and it should behave as you expected.
If it does not work, create a new control with these instructions.
As I understand your question, you have a form with contacts based on a table Contacts and that table contains a field called either Contact_Type_ID or ContactTypeID. You wish to display the description of the contact type from a table Contact_Types.
You do not need to join tables for your combo, it should be very simple. The key, as you suspected, is the Control source, which is the property that relates one table to another.
Control source : ContactTypeID '' or Contact_Type_ID, choose from the list
Row source : SELECT ContactTypeID, ContactType FROM Contact_Types ORDER BY ContactType
Bound column : 1
Column count : 2
Column widths : 0,2
As an aside, you can join tables in a combo and still set the first column to 0 and it will still work, it is all in the correct set up.
i have two item in form it is---1 is textbox and 2nd is combo box.
now i have single value in textbox .
but there is a multiple value for a combobox with is totally depend on a value of textbox....
*i am already add data to the backend files ... in which 1 columns that is called column A it's value is for textbox and 2 column that is called column B it's value for combo box *
When i write in textbox it's dependent ALL value can be get in the combo box.
Can any one solve my problem... It is a row vice search.....
I used a Ms Access for my backend......
How i can create a table that can be i used for a my problem
Give me any reference or codes.
This is probably Category->Product kind of scenario, where ONE Category can have ONE or MORE Products,
Category "Softdrink" can have Products("Coke","Pepsi" etc.)
Category "Harddrink" can have Products("8 PM","BP",etc.)
So when u will put "Softdrink" in your textbox then you want to get the relevant products for it. (Assumed you are using TextChange event)
SQL - select Product.Name from Category Inner Join Product On Category.Id= Product.Category_Id where CategoryName ="Softdrink"
and table structure would be like,
What is the purpose of BOUND COLUMN property of listbox?
The bound column is a number that represents what column from the row source will be used to set the value of the Control Source (if the list box is bound).
Note that you can’t use a column name here. So you don't set the bound column to a column name, but you must use a column number.
Another issue here is that the column number starts at 1 (not zero). Note that OFTEN the 1st column length is set to zero. That allows you to have a list box with something like
select PartNumber, PartDescripton from tblParts
The list box will display the part description, but if you set the bound column = 1, then the listbox will return the PartNumber despite the fact that the listbox is displaying Descriptions (since you set the length of the 1st column = 0. If you set the bound column = 2, then the listbox will return description. Note that you can grab any column value from the list box by using
([lstBox1].Column)
Note that in the above, the column feature is zero based. So, 1 = 2nd column
It's the column of the data set that is used to set the value of the listbox. For example, if it's bound to a dataset with the query:
select firstname,lastname,userid from users;
then setting the bound column to userid (3 in the above example) will cause the user ID information to be returned as the listbox value.
A bound column is the data that the form is going to save. For instance, if you have a list box or combo box that lists employeeID and employeeName and you set the bound column to 0, the form will save the employee ID number from
the selection and insert that value into the corresponding table.
You can test which value you are referencing this using this vba:
Private Sub ComboBoxName_AfterUpdate()
MsgBox ("bound column is: " & Me.ComboBoxName.BoundColumn & ". value is: " & Me.ComboBoxName.Column(0))'change 0 to whatever number column is bound
End Sub
The bound column rule applies even if the first column is hidden on the form. For instance, the user could select "Mike Jones" from the employee list, but the form is going to save Mike Jones' employeeID for data uses (this ID could be stored in a table of sales records, etc.).
