I have created a Userform with a ComboBox for purposes of entering client names and information about their children, their names addresses, etc. The data entered will be used to populate various legal documents, and in many cases the clients will select their children (and the children's information) repeatedly. Understanding this to be the case, I have each entry .AddItem'd to the ComboBox List as I enter the data. So far so good.
But I am now trying to set the MatchEntry property (or something else in a manner which will allow me to "find" a former entry in the list and then select it or override it). The MatchEntryFirstLetter property, if active and nothing matches it, won't allow a new entry, it just flashes-back with the letters I type. MatchEntryComplete forces me to use a former entry (for instance if I have earlier entered the client name in Lower Case, MatchEntryComplete finds the Lower Case name but won't let me override it with an UPPER CASE version. Ho-hum.
So before I struggle further (and abandon this to MatchEntryNone), is there a way to structure the ComboBox (or is there a form of VBA code) such that as I enter text in the ComboBox it will simply "search" for a match, and then release me to either select the match or override it with a new entry?
Thanks in advance for your answers.

AFAIK, ComboBox already have that feature.
You just need to:
set MatchEntry to 1 - fmMatchEntryComplete
set Style to 0 - fmStyleDropDownCombo which are actually the defaults.
Consider below:
Private Sub UserForm_Initialize()
Me.ComboBox1.List = Array("Entry1", "Option1", "Item3")
End Sub
Say we have a UserForm1 with 1 ComboBox named ComboBox1.
If we run the form, it will look like below after typing O and p.
If you type another letter say y, it will automatically be overwritten.
If the searched match already satisfies your search, the just move on to next control either by using mouse or Tab key. Is this what you're trying to do or did I misunderstood your question?

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 am trying to put a number picker in a form in MS Access 2007. Here's an example of what I am trying to make:
I cannot find this in the default form controls, and have tried to make one myself using a listbox. Listboxes can be modified to look just like the number picker above, however the arrows only change the view, of the list, and not the actual selection (that is the value). For example, with the list box, if I have it range from 1 to 3, and default at 1 - when I change it to 2 via the arrows, the value of the listbox does not change, and is still one.
Does anyone know how to get a number picker in Access?
So you want to create a list of numbers and allow users to change the value displayed (AND stored as the control's value) using up and down arrows, such that they select the next or previous in the list.
I would suggest creating a text box and two buttons. Populate an array with the list of values. When a button is clicked it would:
A. Find the position in the array of any value already entered into the text box (eg loaded from a database)
B. Get the next or previous item from the array.
The array is populated as required (probably when the form is opened).
If you just need to allow the user to enter a whole integer number (ie a number spinner) you would do as follows:
Create one using a (locked) textbox and two buttons. Just add a textbox (name it something like txtValue) and two buttons (btnUp and btnDown), then add code like this to the Click event of those buttons:
Private Sub btnUp_Click()
Me.txtValue = Nz(Me.txtValue, 0) + 1
End Sub
Private Sub btnDown_Click()
Me.txtValue = Nz(Me.txtValue, 0) - 1
End Sub
You could add if statements to limit the data being entered
Or you can use a 3rd party control.

There are probably more, but be aware that using these sorts of controls in Access is unsupported, and there is no guarantee moving forward that they will work in Access. You're far better off using the native methods described earlier.
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.
I have a two column list in my combobox and when I choose one of the items in it using the drop down list, it stores (what I see in the textbox part of the combobox) only the value I selected (wether it's the one on the right or left column according to boundcolumn)
My question is: Is there a way to store(or present-that is my goal) in the textbox part of the combobox, both of the columns of one row selected?
For example: [column1] Daniel [column2] Smith. And in the textbox I want: Daniel Smith (and not just Daniel, or Smith on they're own)
What you describe is theoretically possible, but with restrictions.
Even when you didn't ask for that, here comes my idea:
Like described here you can change your ComboBox's text without changing its value. This allows you to 'store' the underlying value while displaying both columns in one.
Listen on the SelectedIndexChanged Event and change the text property as follows:
Sub ComboBox1_SelectedIndexChanged()
ComboBox1.Text = ComboBox1.Column(0) & "-" & ComboBox1.Column(1)
End Sub
(This is only a basic example.) Can't test it right now, but in .Net you can use CType to explicitly convert the sender argument to a ComboBox variable and access it this way.
The Boundcolumn property can't be changed to multiple values. You can try to use VbTab as a delimiter in the text field but i'm not sure how it will appear.
Edit:
Don't forget the default values. I think your Text field should show both columns before the user clicked on the list the first time, too.
You can set a combobox text field to use data from multiple columns but you may need to write some code to do it.
Try http://www.contextures.com/Excel-VBA-ComboBox-Lists.html
Code in Form onLoad:
country_combo.RowSourceType = "Value List"
Code in a reset function:
Dim lListIndex As Long
With Me.country_combo
For lListIndex = .ListCount - 1 To 0 Step -1
.RemoveItem (lListIndex)
Next lListIndex<br/>
End With
Code to populate country combo:
*For n = 1 To numCountries*
*countryCombo.AddItem (countryRS.Fields("countryName"))*
*countryRS.MoveNext*
*Next n*
I'm having a problem that occurs AFTER the code to populate the country combobox runs. The values are there as I can run Debug.Print(countryCombo.Value) and it prints out the name of the selected country, but I can't see the values in the combobox at all. They're invisible, and as far as I know there is no visiblity property for specific items, unless I'm completely mistaken.

I think you should probably use Access's GUI tools to do what you're looking for. In design mode, click on the field you are trying to populate, then click the "lookup" tab. You can then specify a table to populate the field with and your forms should automaticly update as well.
I've also seen what you describe here - as far as I can tell, it's a bug within Access (I was using 2007) that only occurs when you programatically mess with the contents of a combo box. It does not happen every time. The issue corrects itself if you highlight the text that is in the combo box.
I am experiencing a similar issue with Access 2003. Based on the selection of one combo box, the row source of a listbox is set to an SQL string Basically a SELECT DISTINCT [MyField_Selected] FROM MyTable. For some fields the values are visible in the list box and others it is not. The values are there however as I can access them via code. To make it more interesting it works fine in Access 2007.
Just found the resolution on another forum. Check the format property of the field(s) in question on the table. In my case, when Access 2007 created the table, it put an # format in there. I removed that and all works great!
