Save Calculated Values From Form to Table
Save Calculated Values From Form to Table
How do I store calculated values from form to table without making a query? In few of my fields I have expressions and every time I save it only the data I filled in will be saved in the table but not the calculated ones.
Access 2010: User Function displays #TYPE! on Form - How to Hide?
I have an Access 2010 Form that is used for inserting data into a Table. The Form also shows calculated values (from User Defined Functions) in Text Boxes, these calculated values are not saved in the Table.
When I move to a New Record with no data inserted on the Form, my Text Box calculated values show "#TYPE!", obviously because no input variables have been inserted in thedisplayed New Record.
How do I stop the display of #TYPE! and have the Text Boxes remain simply blank until appropriate data is inserted into the New Record.
Calculated (vba) textbox in access form empty with value
I have a form in access that has several textboxes with calculated values (VBA function, returns variant(always currency) value). When I open the form (and other forms that use calculated fields like this), it won't show the contents of the textbox. The textbox always has a value (either 0,00 (valuta type field) or calculated price (subtotal, BTW (taxes) and total price)).
It starts showing the values in the textbox when it gets the focus (cursor on it/click on it) for every field, until I go to the next/previous record or close the form. When the form is closed and later reopened or gone to the next record (see onCurrent function), if the calculated field has focus when switching records/(re)opening only the field with focus shows it's value. All other calculated fields keep hiding their values until they get focus (once) again.
Anybody knows of this problem and how to solve it (permanently)?
BTW, I'm using windows vista 32-bit with Access 2007 on this project
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.
Is there something better?
Currently if I want to loop through rows of a table and perform a calculation (and save it), I do a MAKETABLE query which includes a new column to save the calculated value, then run itall through a recordset in VBA.
Can anyone help in advising a method without creating a table? This would save on memory
Expression builder help
I'm having a little trouble.
I 've got my form created and the table created and I'm pulling the values that are typed into the form into the table. Most all the values that are typed go directly into the table, butthere are a couple that have to be calculated.
I can get the value calculated, but I can't get it to import into the table, or I can get a value to import directly to the table. But I can get both to work at the same time (this is all for one box).
Here is the expression I use to calculate the value (but this value will not import):
The value needs to be imported into the "1 Total Cost" field in the table.
How To Recalculate All Records
I Made a command button to recalculate the field values (For Emergency if somewhere accidentally was left not calculated)
here is My Code:
Me.Sumall = Me.Quantity * Me.Unitprice
It works only the current record (Which I See on the form)
My task was: To search the given field values and if there was not calculated then to be recalculated that field values (With Given Criteria
Calculating average in table
I am in the process of developing a data table and am experimenting to see if calculated fields work correctly before actually entering real data. A form
is used to enter data and place it into the table. The form correctly places data into the table. I have a problem with one of the calculated fields in the table. There are six other numeric fields (columns) which I need to average.
The data represents multiple physiological measurements on the same person. Each field (column) is important and the average of the values is central to the data.
I need to calculate the average of the six fields and permanently store the average as a field in the table since the values will be used in a report and it will also be exported to a statistical program.
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
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
I am having problems with a calculated field, I have two tables, the first is a client information table with many different fields, and the field I am having problems with is a field "totalbanked" which I am trying to get a value from the second table "cashflow".
The second table is used to record many cash flows which are linked to the first table with a one to many relationship.
eg it has an id which is linked to the main form and a fee value that can be added. What I would like to have on the main form is a field that sort through the data in the cashflow table and returns only the values that have corresponding ID in the subform to the ID in the main form, and then sum these values.
I have tried to use the following in the expression part, but it does not work. =Sum(IIf([cashflow].form![ID]="ID",[cashflow].form![fee],0))
How do I create a calculated sum field in Access form?
I am new to Access and need some help with creating calculated fields. I am trying to create a calculated sum field in a form, the sumfield would add the values of 5 fields in a table (all 5 fields are currency).
I created the calculated field (text box)and using the expression builder created sum of fields1-5, and it works fine so long as all 5 fields contain a number or $0 in them.
If 1 or more fields are blank then I get nothing in the calculated field. I think the solution has something to do with the IsNull function but I'm not quite sure how to create the formula in Expression Builder or how to use IsNull.
VBA to save values entered in a unbound form
I have a form containing unbound text boxes which the user will enter data into. I want to write some code to save the values to a table. There are four different text boxes/values I want to save for the last three rolling months (so potentially 12 values will be saved). I have the following code which stores the months in an array so that I can update each month at a time.
I keep getting an error message saying "Run-time error '3021: Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record
User keys data into a Form Control which triggers a VBA event procedure call.
The VBA event uses value of user input to perform several calculations. Result
of each calculation in then placed into proper control (me.NumA = result1
me.NumB = result2.) during the VBA call.
Values for calculated controls (NumA, NumB.) do not display on form
in their designated places. Please note that the controls containing the calculated fiels are coded as NOT enabled (but visible).
I know the values are properly placed into table because if I reprocess form all the previous calculated data displays correctly (before user even has a chance to perform any entry action)
Calculating avg value from a report
I have created a report from a table. I have taken two date fields and calculated the difference between the dates in the report. The calculated value is not stored anywhere. It is generated only on the report. Now I need to take the average of these generated values with some conditions. Since I dont have the values of this field in the table how do I calculate the average
saving calc result
I seem to have failed to understand something fairly fundamental. Say I have a query form with 4 fields, height , width , calculated area:[height]*[width] and area:[calculated area]
In the querie's table and also in the querie's form there are only 3 fields, height, width and area. When I enter 3 and 4 in the form, the result 12 appears in the area control on the form as it should.
But when I save the form and then look at the table, the width 3 and the height 4 are saved - but the area 12 is not saved and is blank.
As I say, I seem to have failed to understand something fairly fundamental.
But my real question is this - How do I go about saving the result of a calculated query field into a table in such a way that even if the calculation is subsequently altered, the original result remains recorded in the table unless it is deliberately overwritten by saving a new calculated value? I've been puzzling over this for some time and can't see how to do it. Can anyonehelp me with that?
I am trying to enter data via a form which has a save button when clicked should record this entry in the associated table.
(The record source for the form is the table).
The problem is, the form is saving only one record, and when I change the values on the form and hit save, it just overwrites the one record in the table.
acCmdSaveRecord not available?
I've set up several functions to create default values for certain fields in a form when it opens with no underlying records. Sometimes I need to add data to this form, and sometimes the default values are sufficient. I want to be able to save the record on the form in the latter case, but neither 'Save Record' on the Records menu, nor 'Do.Cmd Runcommand acCmdSaveRecord' (from a button created for the task) will work. Its as though the form isn't aware that these new values exist to create a new record from when only default values are present. When the form opens with its default values, both the Next Record and New Record buttons on the navigation bar at the bottom of the form are greyed out. If I edit one of the other fields on the form, then everything returns to normal. I want to use acCmdSaveRecord to automatically save the default values to a new record when the form opens. What must I do so that this will work?
How can I get percentile value of a column of values in a calculated field?
I'm a new user to Microsoft Access and I am trying to make a query that has a calculated field that calculates the percentile value of some values in a table. I was wondering (besides VBAor any other coding) how I can get a percentile value in Access?
placing a calculated field from a form into a table
I am creating a database for a library. Fines are calculated via a query and are viewed in a form. However, the calculated fine needs to be transferred to a table when the book is checked in because all the original records which are used to calculate the fine are deleted at that point. Can anyone tell me the code to write to place the calculated field from the form into a table? Details are as follows:
Form frmCheckIn has fields Client ID and Fines (fines is the calculated field).
Both of these fields need to be placed into tblFines
I have a command button that deletes the record, but I need find the code which will place ClientID and Fines into the tblFines just prior to the checkout record being deleted
