Find Table And Field For A Form Control

Jan 7, 2008

Given the firmname and textbox name is it possible to programmically get the fieldname and table name where the data for that control is held.

I can use .controlsource and .recordsource

But is possible that .controlsouce is an alias of the actual fieldname.

Similarly the recordsource could be a query, from that I want to get the actual table, complicated say if two tables in the query had a field with the same name (even if only one was referenced)

Thanks.

Tables :: Find Control Bounded To Field

Jul 13, 2013

I have:
1) a table (T) with fields (F1, F2, .... , Fk, .... Fn). I do not know "n"
2) a form (F) bounded to this table

I know that I have a control bounded to field Fk.

How I can find what control is ?

Something like this:

Dim MyCtl As Control
Dim ctl As Control
For Each ctl In Controls
If ctl IsBoundedToFieldFk Then
Set MyCtl = ctl
Exit For
End If
Next ctl

New Field Does Not Show In Control Source For Form Control

May 28, 2015

I have table that I had to add a new field to which we update with a form. I tried to add a control for the new field but the field does not show up in the list for the control source. I am trying to add a list box to the form with a blank and 5 options.

I have attached screen shots of the table design and the form. The table has the field in datasheet view and I have manually entered a few entries in it but it still will not show in the control source for the form control. The top section of the form is where we enter and select the data for the new records. The bottom section (circled in red) autofills the matching record, from separate tables, for updating with the new entries.

I have added form controls for modified fields in the past so I am confused about why this is happening.

Queries :: Find Data In One Table And Put In Field Of Another Table Then Update

Nov 7, 2013

I have an "order details" table that needs to populate a field called "Voucher" with data from another table called "codes". The "codes" table also has a true/false field called "allocated" because once allocated the code cannot be re-used.

I am trying to work out how to automatically allocate the next unallocated code in the "codes" table to each record in the "order details" table when that order details record has a DiscountID of "92".

Order Details Table Fields and conditions/criteria:
ID - primary key
DiscountID - only when the DiscountID = 92
Voucher - only populated when Discount ID = 92

Codes table Fields and conditions/criteria:
ID - primary key
code = text field with a code like "einstein01", "einstein02"
Allocated = False

Is there a way to put the next available code into the order details record then mark that code as allocated in the codes table. Then, move on to the next order details record that has a discountID = 92, input the next unallocated code and mark that code etc. etc.

Ideally, I would like to do this to happen via an event when the Order forms button "Close" is clicked.

Forms :: Find Data Using Field In Form

Jul 19, 2013

I have a form that is bound to a query. The user inputs their id in a text box and the form should find the corresponding record with 5 different pieces of data displayed in separate text boxes. There is at any given time only one record set per id. The query has in the EmpID the criteria: [Forms]![frmProdStopEntryNew]![EmpID] to reference back the EmpID as the filter.

On the form, after the employee enters their ID, the afterupdate should pull-up the record that corresponds to that id. The code for the afterupate is:

Code:
Private Sub Emp_ID_AfterUpdate()
Me.Filter = "EmpID = '" & Me.Emp_ID & "'"
DoCmd.RunCommand acCmdApplyFilterSort
Me.StopTime = Now()
ReasonID.SetFocus
End Sub

I also have a form load to go to a new record just so that the form is blank when the user enters it.

Code:
Private Sub Form_Load()
On Error GoTo Form_Load_Err
DoCmd.SetWarnings False
DoCmd.GoToRecord , "", acNewRec
Form_Load_Exit:
Exit Sub
Form_Load_Err:
MsgBox Error$
Resume Form_Load_Exit
End Sub

The problem I'm experience is that the query to find the record has a 50/50 hit and miss success rate. I think this is because the form load gets activated each time the query is refreshed afterupdate. And the form load has the new record syntax so it sort of nullifies it each time. How do I fix that?

Forms :: Control Setup - Bind List Box Result To Table Field

Nov 5, 2013

I want a List Box on a Form that takes its available drop-down values from tblDiscipline and puts the value selected into the Discipline Field of tblEquipment.

The problem is I set the Control Source of the List Box to tblDiscipline (so the List Box can use these values for the drop-down selections) and when I make a selection it tries to put it back into tblDiscipline instead of tblEquipment, because I can't find anywhere to set the table that the result should be Bound to.

How can I set up a control, such as a List Box, so that it gets its values from one table but returns them to another?

Concatenate Form Control In A Table Name

Jul 21, 2005

Is it possible in Access SQL to concatenate a control into the select statements table or fields? Such as:

SELECT fldtotal & [Forms]![frmTest]![lstYears] & fiscal
FROM tblTotals & [Forms]![frmTest]![lstYears] & Archived

The statement would normally be:

SELECT fldtotal2003fiscal
FROM tblTotals2003Archived

Unfortunately, I am querying somebody elses tables. They archive the data yearly into a new table to control bloat. Instead of yearly having to create a new query for the new year, I was wanting to just have a form that had a list box of years. Then the user can just select what year they wish to query, and the query is automatically updating the field, table, where condition, etc.

I do not know if this is available in Access as it is in Oracle / Coldfusion. Thanks for any help though.

General :: VBA Error Referring Control Field In Subform Using Main Form

Feb 22, 2013

I believe I did this before awhile ago but for some reason I keep getting an error.

I have a Mainform (frmMain) that has a Subform (frmSub). On frmSub I have 2 comboxes (strCom1 & strCom2) one is set to invisible (strCom2.Visible = No).

So using the "On Open Event" of frmMain I want make strCom2 visible if strCom1 = "Read Only". Ofcourse I will also need to place the vba on the On After Update event. Below is what I have so far but doesnt work.

I get Run-time Error 2427 "You enetered an experssion that has no value"

Code:

Private Sub Form_Open(Cancel As Integer)
If Me!frmSub.Form!strCom1.Value = "Read Only" Then
Me!frmSub.Form!strCom2.Visible = True
Else
Me!frmSub.Form!strCom2.Visible = False
End If
End Sub

Queries :: Making Default Value Of A Form Textbox Control Minimum Value Of A Field

Mar 21, 2014

Expressions in Access have given me some trouble before. Mainly due to inexperience. I hardly ever work with them. What I am trying to do is make the default value of a form textbox control the minimum value of a field A in a table A. The datatype of Field A is Date.

So far I've got:

=Min([table A].[field A])

In the Default Value of the form's property sheet, but this just returns a blank value. I've had a look in the table and there is no value that is blank in field A.

General :: Form Control To Combine Multiple Field Values Into A Single Text Box?

May 10, 2013

I'm trying to set the control source for a control on my report that describes the number of portions that goes into a box. Sometimes there is a specific number of portions per box and sometimes it's a range. When the number of units is specific, then it is entered into the MasterCaseMinUnits Field. If there is a range of units possible than the min is entered into MasterCaseMinUnits and the max is entered into the MasterCaseMaxUnits.

I want my report to look at the mastercasemaxunits, if it is blank it will only display what is in the MasterCaseMinUnits field. If there is a value in the masterCasemaxUnits field, then it will display the masterCaseMinUnits & " - " & MasterCaseMaxUnits. this is the code I'm Using:

Code:

=IIf(Nz([MasterCasemaxUnits],[MasterCaseMinUnits])=[MasterCaseMinUnits],[MasterCaseMinUnits],[MasterCaseMinUnits] & " - " & [MasterCaseMaxUnits])

When I run my report, the control displays: #Type!

Forms :: Rota Table - Continuous Type Form In Tab Control

Oct 23, 2013

I am mid way through a Access db and have a solid idea what i want from a form. The idea is for a rota display and edit form.

a tab control with 5 tabs (-2 weeks, -1 week, current week, + 1 week, + 2 weeks) and when the user clicks it lists all the employees (Employee Table) with any found rota entrys (Rota Table) populating into a text box type table with employees information blank where no rota information has been entered.

then the user can edit / add shift information from that table and hit save.

the main rota information is inputted by an excel import but this is done once a month and adhoc changes will be needed (holidays absence etc)

the only thing i found like what i want is a continuous form (which ive never used before but been told that wont go in a tab control)

How i would accomplish this (code snippets - doesnt have to be detailed just the fundamental functions so i can add modify to suit the information the sql's i already have its just the form controls.)
