Assign Value to Control from Calculated Field in another Form
Runtime Error on assigning a ComboBox value to a control on a Form
I have this control, ctljoinEmployeeId, on my form and it is empty at the time that I want to assign a value to it.
In the add a record mode, I fill-in a combo box, cboEmployee, by choosing an employee name. In the After Update event for this combo box I assign the EmployeeName to a control, ctlEmployeeName, and all is well. Also at this point I want to assign the EmployeeId to a control, ctljoinEmployeeID. In the AfterUpdate for the for the Employee combo box the code to assign the EmployeeID is: Me.ctljoinEmployeeID = Me.cboEmployee.column(0). Both of the data types are text and the ctljoinEmployeeId is bound to a table field whilst the cboEmployee is bound to yet another table field, more correctly two fields, the name and id.
Any idea why I am getting a runtime error on this assignment or any suggestions as to how I can assign the cboEmployee.column(0) attribute to ctljoinEmployee control
sort by calculated field
In a report I have a calculated control which is the difference between two numbers. Is there any way that I can sort using that control? When I refer to it in VBA in an orderby it asks for the parameter of that control since it is not an actual field. Neither can I sort by it in the sorting & grouping options again because it is not an actual field
Insert calculated date into message
I have a date field that caculates on click of a command button in a form. I like to use that calculated date in a message set in the body of an appointment reminder.
I want the message to read:
"Connection Date [insert connectdate from calculated field]"
Me![frmAppoints]![ApptNotes] = "Connection Date" + "" + [ConnectDate]
I've tried various combinations of double quotes and flanking the calculated field in # signs. The result is either nothing of it returns the words [ConnectDate] rather than entering the actual calculated date.
Can someone guide me on the proper way to call a field like this to return the value calculated rather and the control name?
Update (Refresh) Calculated Field
I have a subform which refers values to controls on a form on which I have a calculated field -
originally I used CalculatedField Type then I changed it to txtBox with Number as Type
Control Source =[field1]+[field2]+[field3]
Now the calculated field does not show anything until all the controls have an entry. Sometimes (most times) not all will have entries. I put a form refresh on the main form but still no value.
So then I did Me.Recalc on the AfterUpdate of the Main Forms Controls Then I did Me.DelTotal.Recalc | And a refresh button in thesubform, just nothing until all the controls in DelTotal Control Source have an entry?
Saving the value of a calculated field to a table field
I have a calculated field in a form using this expression typed in the control source box =[Begin Date]+[Duration]
Since I can't bind this field to a table field I would like to transfer the value returned by this expression to a field in a table.
How to Fire VBA Code when a Calculated Textbox Changes Its Value
I'm using MS Access 2003.
I have a textbox control txtAmountOutstanding whose Control Source is as follows:
(txtAmountSettled is itself calculated from data in a subform).
I'd like to be able to programmatically insert a Settled Date into another field on the form whenever the value for txtAmountOutstanding first becomes zero.
I tried to do this by entering some code in the On Change event for txtAmountOutstanding, but apparently this event does not fire as a calculated field
Naming a Calculated Field
The Control Source for a calculated field on a report is =SUM(expresson). Can you apply a name to the field (like you would in a query) and use that name in another field?
I see that there is a Name property for the object, but I have not been able to use it for additional calculations.
Why no Display Control with a Calculated Field
As per title. This does not seem to be possible, unless Display Control can be called in SQL code? I doubt it, but maybe.
This really annoys me. I want a check box to come up for my CALCULATED FIELD in my Table, and especially in my Query. Yes my caculated field will deliver True or False.
There's nothing like a ticked box to jump out at you. Much better than a solid block of Yes/No.
Need results of calculated field to appear in table
This question concerns a calculated field on frmNCC. they wanted this form as part in Access instead of in Excel where it belongs. So I slaved over the myriad calculations and came up with a beautiful, perfectly functioning form.
UNTIL. I remembered that I need to be have that total field [TotalNCost] in tblNCC because it needs to bedownloaded into a spreadsheet.
Assumptions and attempts: I assume I need to create a field in tblNCC called TotalNCost and make that the control source for this field. And I tried that. I then moved the calculation into the AfterUpdate of the form.
This caused conflict with the Me.Recalc expressions. I tried deleting the Me.Recalcs and the form ceased to function.
Create a calculated control
You can use calculated controls to display the results of a calculation. For example, if you have a report that displays the number of items sold and the price of each unit, you can add a calculated text box that multiplies those two fields to display the total price. The Control Source property of the calculated text box contains an expression (expression: Any combination of mathematical or logical operators, constants, functions, and names of fields, controls, and properties that evaluates to a single value. Expressions can perform calculations, manipulate characters, or test data.) that multiplies two fields (the number of items times the unit price) to obtain the result.
What do you want to do?: Create a calculated control, Change a bound control to a calculated control, Learn which types of controls can be calculated controls.
How To Assign A SubForm Value To A Control In Main Form ?
I have referred to this link, however, still cannot figure out the right approach to code.
As illustrated in the attachment below, can anyone assist me on how to assign a subform value to a control in the main form
ACCESS 2007 Calculated primary field
I've set up a simple database for some survey work. Data tables are linked by a primary key consisting of a 10 to 12 digit location code (picked up from a drop-down list) and a 2 digit survey number - all stored as text. Rather than use compound relationships I would like to combine these into a single primary key.
I know calculated fields in tables are wicked..! but how can do I do this automatically in ACCESS 2007. I can combine the two easilly in a calculated control in a form.. but not directly into the primary field. Although the result does appear in the control - I get an error message telling me I can't have a null entry in the primary field....
Calculated Controls for Data Entry
Okay so I've got some fields that need to be filled out pertaining to financial issues that I hope to make easier and more efficient. I have one field that represents the "Base Cost" that I expect to fill in myself.
The second field is a calculated "Acceleration". This value is almost always 0.3*[Base Cost]. I can enter =[Base Cost]*0.3 in the control source for the field in my form and it looks great in the form.but I need this data to save the "Acceleration" value to the record in the table.
A second concern is that occasionally there are deviations from the [Base Cost]*0.3 formula and I need to be able to enter those and have it save to the table.
The same applies to my "Total Cost" field, which is simply =[Base Cost]+[Acceleration].
I put this into the calculated control and it works just fine but doesn't save in the corresponding table.
Control addressing on subforms
I have a subform that contains a bunch of controls (aka color-coded boxes)
that I want to be able to assign OnDblClick actions to. Other data defines
color/position of my boxes, but I need to programmaticlly modify what happens
during the OnDblClick of each box.
Ideally, I wanted to write 1 macro that I can assign to the control(s) as
VBA is rearanging the subform. The problem I am having is:
How can I get the Control Name off of the sub-form? I have tried versions of:
CurrentObjectName = Application.CurrentObjectName and
Set ctl = Screen.ActiveControl
but I keep getting pointed to the main form not the subform. Any
suggestions on how to tell which control has been clicked on
Using calculated fields from query in a form/report
I have information from calculated fields in a query that I would like to be able to filter and display in a form or a report.
The calculated fields are part of a pivot table/pivot chart that I use to sort the data that is collected. the problem is that these are not any run of the mill calculated fields, we're talking about an IIF statement that has four different conditions that is based on another calculated field in the query.
Ive tried to create forms and reports from the query but the calculated fields wont transfer over.
Am I stuck recreating the calculated fields in a the form or is there an easier way
Creating a Calculated Field
Jenny would like you to add a calculated field to the Instructor table. Label this field: Annual Salary
Data Type: Calculated
You obtain this information by multiplying the Instructor Pay Scale which is an hourly rate by 2080 hours
Label this field Annual Salary
HOWEVER, in the book, it shows you clicking (in design view) from Text to Calculated. I don't have a calculated option.
Therefore I can't create a calculated field.
How do I reference a Calculated Field?
I have a form that is a search form to filter results and open another form to display the results. Things work fine when I'm comparing entered values to columns in my table, but now I'm trying to add a little more functionality and running into trouble.
On my form that is displaying the data, I have a calculated field (a number). I want to add a search criteria that says. If calculated field is > "entered_value" Then .
What I can't figure out is how to reference the calculated field in Visual Basic. When I did dates I just referenced the column, but since this calculated field doesn't have a column (and from what I have read I should not create a column to store it), I can't figure out how to reference it
calculated field from calculated field?
I have a report that is grouped by an ID number as a header, then a detail section displaying that relates to the ID number. There are two currency fields, and a calculated field whichdisplays the sum of the two currency fields for each record.
Then I have a footer of the ID number which has a calculated field, which I want to be able to total the calculated field for all records in that group. What's the easiest way to achieve this?

Calculated Control With a Query that Counts
I am interested in designing a query that will count the number of records that meet specific requirements. I want to be able to count the number of records where one or more fields meet certain requirements, such as where the age field is between 38 and 40 and the color field = blue. I am sure this is fairly trivial but I just can't see how to do it. I can see how to use a calculated control add numbers in a field together
Refer to previous calculated field
I was just wondering if there was any way to refer to a calculated field in the same query.
For example if the first calculated field was - Total: ([Quantity])*([Price]), could you add another calculated field - Inc Tax: ([Total])*1.175.
At present I am having to type the whole formula in the calculated field again which seems to work for some queries, but not for others, no matter how I fiddle about with the syntax. The other way is to create another query and refer to my previous query. Both these methods seem extremely cumbersome and I was wondering if I have missed something with referring to a prior calculated field.
The query above is just an example, my query formulas are actually fairly long and for editing purposes it can be difficult to correct them.
