Dlookup
here is a hack since your form is Continuous, there is actually 1 currency combobox.
so changing the rowsource of the combo affects the entire form, making some
of the "values" of combo disappear.
i change the query qryPmtProposal to add currency from currency table (the new calculated field is CY).
next i added a textbox (txtCurrencyName, see it in property window) and add CY as it controlsource. in the property i also disallow Tabbing to this control. then i right-click and Position->bring to front. While the currency combo the Position is sent to back. I align both controls correct (reducing the width of the textbox).
next i remove the Border of txtCurrencyName and add code on it's GotFocus to move the focus to the combobox.
next i Overlay (the txtbox on top) the txtCurrencyName to the Currency combobox.
it is now correctly displaying (hopefully).
Hello George,
That's exactly what I am looking for.
I have added the codes in the afterupdate as the link prescribed.
I also added it to the on focus event of cboCurrency.
Issue:
instead of showing the currency name it shows the ID.
here is my code:
Private Sub cboCoName_AfterUpdate()
' Set the Currency combo box to be limited by the selected Company
Me.cboCurrency.RowSource = "SELECT Currency " & _
"FROM tblBankAccounts " & _
"WHERE COIDfk = " & Nz(Me.txtCOID)
End Sub
this is on tblBankAccounts.Currency rowsource with bound column 1 and column count 2 and it shows the actual currency name and not the ID as it does in the above code.
SELECT tblCurrency.ID, tblCurrency.Currency FROM tblCurrency;
Do you happen to see where I am wrong?
thank you
Hi George, yes, you are correct. I had a lookup on tblBankAccounts.Currency.
I changed it to a text box and number. I have not used access in a few years and I remembered something about not putting lookups in tables.
Now My qryPmtProposal looks like: (note I added tblCurrency):
SELECT tblPmtProposal.ID, tblPmtProposal.CoName, tblPmtProposal.Amount, tblCurrency.ID, tblCurrency.Currency
FROM tblPmtProposal LEFT JOIN tblCurrency ON tblPmtProposal.Currency = tblCurrency.ID;I still have the issue of the currency ID displaying in qryPmtProposal instead of the currency name (ie USD instead of "1").
here is the code on AfterUpdate in qryPmtProposal:
Private Sub cboCoName_AfterUpdate()
Me.cboCurrency.RowSource ="SELECT Currency " & _
"FROM tblBankAccounts " & _
"WHERE COIDfk = " & Nz(Me.txtCOID)In the above query, how can I adjust to see the name of the currency instead of the ID on Me.cboCurrency?
thank you George.
The Foreign Key field in tblPmtProposal will be the Primary Key in tblCurrency, as you now have it set up.
The row source for the "downstream" combo box will need to be two columns from the currency table:
Me.cboCurrency.RowSource =
"SELECT CurrencyID, Currency " & _
"FROM tblCurrency" & _
"WHERE ID = " & Nz(Me.txtCOID)That is assuming that the "upstream" combo box is named "txtCOID".
Column 1 (the first column on the left) is set to 0" width so it is hidden, and Column 2 is set to a width wide enough to display the text value.
Actually, I have a demo on my website that might be helpful. It uses a different approach to filtering, but you can probably get some ideas about the overall process.
One other thing I do, and suggest you consider, is naming conventions for Primary and Foreign Keys. There are different points of view, though. I always rename the default "ID" that Access assigns to Primary Keys to reflect the table for which they are the PK, i.e. CurrencyID instead of ID.
Then, I also use the same name for the Foreign Key field in the related table. Others use suffixes like "CurrencyPK" and "CurrencyFK".
The main point is that having two fields called "Currency", one of which is the text value (in tblCurrency) and the other of which is the Foreign Key, not the text value (in tblPmtProposal) and a number, can be confusing. Disambiguation is important, IMO.
George, many thanks for the assistance.
I am still not getting the tblCurrency.ID to be replaced with the tblCurrrency.Currency (this is the name of the currency). I was getting an error on "ID". There are 2 fields named "ID" and not sure if that is causing it but I changed the names to append the name of the table in front but still was getting errors. I am not sure if in the code you use an underscore "_" or a "."
I can answer one of your queries:
<That is assuming that the "upstream" combo box is named "txtCOID".
The "upstream" combo box is named cboCoName and this is where the AfterUpdate code is placed.
I have pared down the db and attached.
Maybe you could kindly take a peek.
The form in question opens auto and I shaded the field in qstn.
When you click the 1st record and cboCurrency you should see only USD and EUR but I see all 4 currencies as an option and the record below it should only show USD as an option in cboCurrency
grateful for your assistance, George!
