I have an unbound form with some required fields that must be field. I have already executed the vba code to achieve just that. Now my question is how do i specify thefields so that he end user can vividly see those fields. I already have an idea of using red stars but i am open to more suggestions.
You can add (*) symbol in the label that denotes its mandatory to fill.

Error popup after click ok on type mismatch
I am using a combo box to search for records and it is telling me I have a type mismatch. I have been unable to find where this mismatch would be. The combo box still performs the desired function of selecting all records based on their "region"
I am using an ID field which is selected using the combo box but I want to pull through a name as well so I have input an unbound textbox and used VBA on change in the ID to update the name to the corresponding ID in the unbound textbox
Form
For privacy reasons I snipped around some of the other fields showing data.
The VBA in the on_change event in ID goes
Private Sub txtSupplierID_Change()
Me.txtSupplerName.Value = Table("tblSuppliers").SupplierName
Where Table("tblSuppliers").ID = txtSupplierID
End Sub
I'm aware this code could be very wrong but I could not find anywhere else that showed me how to do what I was trying to do. Any suggestions on how to actually do it would be appreciated. If I have not been as detailed as needed or yo have any questions please ask.
Edit for Clarification:
The form is not being used to save data. It is only being used to display data and issue an output to a report.
Code is not just wrong, it is nonsense. Cannot reference a table object like that. And that Where usage is not valid. One way to pull value from a table is with DLookup domain aggregate function. Advise use AfterUpdate instead of Change event.
Private Sub txtSupplierID_AfterUpdate()
Me.txtSupplerName.Value = DLookup("SupplierName", "tblSuppliers", "ID = " & txtSupplierID)
End Sub
Might want to correct textbox name from txtSupplerName to txtSupplierName.
However, should not save both supplier ID and supplier name into this table. There really should be no need for this VBA. Just put DLookup() expression in a textbox ControlSource. For other methods of pulling the supplier name to form, review answer in MS Access Identical Comboboxes for Autofill
In my Access database, I have tables with the naming convention of "t_customers" or "t_orders". I have a combo box which lets me pick from these options. For a better look, I want to have the options in the combo box without the "t_", so one of the options is just "customers". Then in VBA, I can access the combo box's value of "customers" and then pass that as a parameter to my function which will export the contents of the associated table "t_customers" to an excel file.
Is this possible to do? I can think of using a select case statement and for each combo box value I manually assign the related table value, but there has to be a better way. Is there some sort of short cut that does this in Access using a relationship or similar feature without coding? Or is there a simpler way to code this?
EDIT:
I am also trying to get the value of the current item selected in my combo box named "cbTable". I have no macros attached to the combo box. I have a button that when pressed it runs a macro which calls my VBA function. In the function I have this code:
Dim cbValue As String
cbValue = cbTable.Value
MsgBox (cbValue)
I get this error:
Runtime Error '424'
Object Required
The error is on the
cbValue = cbTable.Value
line. What is wrong with this code and how do I get the current value of the combo box?
Thanks in advance.
You can set your RowSource for your combobox to
SELECT MSysObjects.Name, Replace(MSysObjects.Name,"t_","") AS Expr1
FROM MSysObjects
WHERE (((MSysObjects.Type)=1) AND ((MSysObjects.Flags)=0));
Then set the Column Count to 2, the Column Widths to 0;2 (the second number just needs to be any positive number) an the Bound Column to 1.
Now when you go to call your function the value of the combobox will be the real name of the table, t-customers, but what you saw on your form was customers.
As for accessing that combobox a few things need to be in place.
Let's say you have a form, Form1, and your combobox, cbTable, is on that form.
So when your form runs it looks like this
Now let's say you have an OnChange even for that combobox
Notice that when you type cbTable it appears in the intellisense (ctrl+space). This tells you that your object is accessible at this scope.
Now if you were in another module where that variable is out of scope you would get this error when you try to compile.
Because Module1 has no idea what cbTable is. However, you can reference anything so long as it's fully qualified. So if we run this test with your form open, and "orders" selected all 3 of these lines are equivalent
Forms("Form1").cbTable
Form_Form1!cbTable
Forms("Form1").Controls("cbTable")
Notice at the top of all my modules it says Option Explicit. This forces your code to basically be checked for syntax/scope validity before you run it. Tools > Options
I have a dynpro with several mandatory fields. Now, I want to implement a button that prefills those fields with suggested values. Further, another button should deactive certain input fields.
My problem is that the button actions are stopped by the empty mandatory fields. Is there a way to skip those validations, if a certain button has been pressend and acces the PAI - PBO handling?
You must execute your action before the mandatory checks bloc other changes.
Instead of
MODULE ... INPUT
you can try
MODULE ... AT EXIT-COMMAND
Normally the AT EXIT-COMMAND allows you to leave the screen, even if the values are missing. But you can use it also to fill mandatory fields.
After filling the mandatory field I would call again the screen to process PBO/PAI again. So the user can see the new changed values.
One question: Could you also fill the values during PBO?
Something like:
MODULE ... OUTPUT.
IF field is initial.
field = default_value.
ENDIF.
I currently have a form. The form contains a subform that displays a Query. The Form also has 2 Text Boxes and buttons for both Boxes. The first box acts as a filter for the query to filter specific record. The second box is intended to be used to hide columns in the query. My issue is that my code will not recognize the text box, or any outside source from my form as a Field Name to be found. Here is my current code:
Private Sub Command137_Click()
Forms![Vermont]![Query1 subform].Form.[Query1 Field Name].ColumnHidden = True
End Sub
Currently if I replace "Query1 Field Name" with any field name that exists in the query the column will hide. However if replaced with anything else I recieve the following error:
"Runtime Error '2465'
Microsoft Access Can't Find the Field '|' reffered to in your expression"
I am pretty sure that I am not referencing the Form Control correctly. I have tried replacing [Query1 Field Name] with the following:
[Text142.Text]
[=Text142]
[Text142]
[Forms![Vermont]![Text142]]
I am very new to VBA but I definitely feel as if this is an easy fix; if possible.
Thank you in advance for any help!
Subform references are always a bit weird. This should work, though:
Forms![Vermont]![Query1 subform]![Text142].ColumnHidden = True
I have a standard form in MS-Access which lists a bunch of orders, and each row contains order no, customer, etc fields + a button to view notes and attached document files.
On request from our customer we should gray out the button btnAnm (or check or uncheck a checkbox) depending on a calculation from two queries to two other tables (a SELECT COUNT WHERE and a check if a text field is empty).
I've tried btnAnm_BeforeUpdate(...) and btnAnm_BeforeRender(...) and put breakpoints in the subs, but none of them trigger. The same if I use the control Ordernr instead of btnAnm.
I'd like a function in the Detail VBA code to be triggered for each "Me." (row) so to speak, and set the row's control's properties in that sub.
What do I do? I've looked at the help file and searched here.
*Edit: So I want to do something that "isn't made to work that way"? Ie. events are not triggered in Details.
As an alternative, could I base the value of a checkbox on each line on a query based on the 'Ordernr' field of the current row and the result of a SELECT COUNT from another table and empty field check?
Do I do this in the query the list is based on, or can I bind the extra checkbox field to a query?
A description of how to do this (combine a COUNT and a WHERE "not empty" to yes/no checkbox value) would be perfectly acceptable, I think! :)*
You cannot do much with an unbound control in a continuous form, anything you do will only apply to the current record. You can use a bound control with a click event so that it acts like a button.
Presumably the related documents have a reference to the order number that appears on your form, which means that you can create a control, let us call it CountOrders, with a ControlSource like so:
=DCount("OrderID","QueryName","OrderID=" & [OrderID])
The control can be hidden, or you can set it up to return true or False for use with a textbox, you can also use it for Conditional Formatting, but sadly, not for command buttons.
Expression Is [CountOrders]>0
You can also hide the contents and add a click event so that is acts in place of the command button. Conditional Formatting will allow you to enable or disable a textbox.
As I understand your question, you have a continuous form with as command button that appears on each row - and you'd like to enable/disable the button conditionally depending on the contents of the row.
Unfortunately you can't do that. It seems that you can't reference the individual command buttons separately.
Having wanted to do something similar in the past I came up with two alternate ways of setting up my interface.
Put a trap into the onClick code for the Button. Which is icky, because it is counter intuitive to the user. But it gets you that functionality now.
Move the command button (and editable fields) up into the form header, and make the rows read only. Your users then interact with the record only in the header, and select the record they want work with in the list below. As I recall this is known a Master-Detail interface.
