Problem With Check Box And Equations
Jan 24, 2006
I have a simple problem that I can’t seem find any help for. I’ve tried searching and browsing the forums with no luck. I have a Boolean (yes/no) column that I would like to be dependent on an equation containing fields in a table. The equation is simple: I have three columns I’ll call them A, B and H.
The Equation is: A*12+B<H
If it’s true then the field will equal yes, if the equation is false then the field equals no.
I’d like to have this in a query that I can base a report off of. I know very little about SQL or VBA so when I see SQL or VBA terms used I can’t always tell what they mean. So if someone could tell me what I need to do I’d also know where to put it. Thanks A bunch!

This being my first post, I hope to explain myself well enough. I am working on a database to do estimations. I will be starting with three main tables - Jobs,items & options. There are options that can be purchased for each item. My problem is that the option price's are unique. Example: There are door hinge options which will need to be multiplied by the number of doors (which is a field) and there are other options which are multplied by the length (another field). Is there a simple way to accomplish this? This may sound stupid but I was wondering if it would be possible to have a equation field for each option???

Ok my goal is to have a calculation in a query that includes a bunch of addition, division, and multiplication. (It uses 10 pieces of data) I tryed typing it in the expression builder but it doesn't work. I don't know if I am setting it up wrong or putting it in the wrong spot or what. I've tried some different things and I either get a blank box in that field or I get a syntax error. Also is there any way I can put the info received by the equation into a field in my table? Thanks

I'm trying to take a database from MS database (Works 7.0) into Access 2002. I've done this before by saving it as a DBase IV file and then opening it as such into access. However, this time I need the EQUATIONS to transfer as well, not just the values. I care little about the form view, or even the values themselves, but need the equations to transfer. Please advise. Thanks. :confused:

I want to create a calculation query that uses different equations under certain conditions. Here's specifically what I need:
If the "Cost_Category" field is "Full Price" then the query uses the following calculation:
Total_Cost: Sum(nz([Program_Cost])+nz([Millage_Fee])+nz([Auditorium_Cost]))
If the "Cost_Category" field is "BOCES" then the query uses the following calculation:
Total_Cost: Sum(nz([BOCES_Number_of_Participants])*nz([Cost_Per_Person]))
I have successfully created these two queries individually, but combining them doesn't seem to work. Here's what I wrote:
Total_Cost: IIf([Cost_Category]=Full Price,Sum(nz([Program_Cost])+nz([Millage_Fee])+nz([Auditorium_Cost])),
IIf(Cost_Category]=BOCES,Sum(nz([BOCES_Number_of_Participants])*nz([Cost_Per_Person]))
It keeps coming up with errors, saying that I misplaced a comma, parenthesis or quotation. I've tried playing with it, changing the syntax slightly but it doesn't seem to work.

I would like to store equations on certain fields and display and edit them in a form.
I can't find a Microsoft Equation Editor control in the list of ActiveX controls. Is it stored as a .ocx file? How is it named?
In case Equation Editor can't be used within Access, is there another third party addin that provides a control with that functionality? It would be great if there were an application that accepted markup code like LaTeX as input so it were easier to implement a code to manipulate equations.

Long time lurker, first time poster.
I'm in need a of a check-in/check-out application for my company. We have about 550-600 employees at any given time and our turnover is about 20-30% per year. Our check-in/check-out process requires our employees to personally visit between 30-40 areas in our company (personnel, safety, credentials, parking, insurance, etc) within the first month of employment. This is currently done manually and is a huge drain on labor, especially when check-in sheets are lost, misplaced or, in some cases, forged.
I'm looking to build a database that would be intranet based, password secure (by check-in area) that would allow the new employee to present at a particular check-in, check-out site, complete that portion of the check-in/out process and then allow the person responsible for the check-in/out to enter the status into the database. At any point in the process, I would want to know the status of the person checking in/out (how long they've been checking in/out and what portion of the process have they completed).
Can this be done in ACCESS?
Thanks

Hello,
I have a continious form containing data from the table "tblToernament".
On that form there is a combobox containing teams that are stores in the table "tblTeams".
The table looks like this:
ID | TeamName
1 | Team01
2 | Team02
3 | Team03
4 | Team04
When I select, for example, Team02 in the combobox I want that value on, after I selected it from the combo NOT to be in the combobox.
Can anybody please help me on this?

Hey guys..
I was working on my project again as usual, which is about transaction of cars coming in and going out (car pool system), So i created a table then a form for this. In the table, i put the option of 'Yes/No'. So, for the form, i want to create a search system which will include a search system.
My Idea:
I want to make a check box, as a search system, so when it is checked and clicked on a command button, it searches for all records with 'Yes'. and if not checked, and clicked on command button, then it searches for all records with 'No'.
Now i did my research, on google and stuff also in the access help but it ddnt help much.
To be honest with you guys, i dont know much of visual basic writing, but i do understand most of it. ( you know, when you understand one language but can speak it?? same way :o ).
So i would request some one to give me instructions on this one. It would really be appriciated.
thanks a million !

Do check boxes have to be bound to be able to save them in your forms? In other words, when you check the box and click save, does the check box have to be bound so that the check mark can be saved? Thanks.

I want to connect a single check box to a record of check boxes, so that when it is on yes (checked) all the other boxes are yes (checked) automatically. How do I go about doing this? Is there an expression I can build for it?

Hi,
Is it possible to change the size of a check box? When I modify the height and width of the checkbox it doesn't appear to do anything.
Thanks

Hi,
I know there is probably a simple answer to this question, but im wondering if there is a way to make the value of a "true" checkbox anything but -1. i'd like the checked box to display a positive 1 in the corresponding table, so that they may be added up for a further query.....
i am working with IIF statements now with no luck,
Please tell me how i can fix it, and if there is a simple way of changing the value to a positive number, or even to a letter or word!
Cheers!

I have a access form that when a user clicks a button it runs a report for that particular record. When the user clicks this button to run the report I would like to have a check box or whatever else you recommend on the form that would become checked once the user runs this report so that they will know that they have already ran a report for this record. If they try to run it again a msg box will appear letting them know that a report has already been created but if they want they can run it again. Any Ideas or HELP?????
THANKS!!!!!!!!!!!!!!

If Me.Check25.value = "no" Or Me.Check25.value = "" Then
MsgBox "You must agree to the terms below.", vbOKOnly, "Required Data"
Me.Check25.SetFocus
Exit Sub
End If

Hi
In my tables I have set a field to Yes/No and the format to be True/False.
When I activate the table it shows the field as a checkbox, however when I create a List Box on a form to that table it displays the fields as True/False, how can I get the list box to also display the field as a checkbox.

Hi. I recently started using Access 2003 to create a contact management database. One of the section is titled "Areas of Interest' with nine categories of nine respective check boxes. I made the nine check boxes and when I click one all seems fine. However when I move onto the next person in the database, the check box clicked on the previous contact is already clicked and continues to be so far every other client. How do I make the check box selection distinct per contact?
Thanks. My apologies if the answer is easy and obvious. Take care.

Hi all,
Employees enters free tekst description of goods in a tekstfield. The question have been asked to query that database to check if they fill in the free tekstformat correctly. I understand that this is virtually impossible but we were thinking abount BLANCS, One character and maybe only values etc etc. In general is there a sysmantic checker or a module or link (Im thinking outload now, a symantic check) who could guide me with this requirement.
Hope I do make sence.

I'm requerying a subform based on selections made on the main form. One of the fields is a check box. This is the code I've got on the Show Data button
On Error Resume Next
db.QueryDefs.Delete ("Search_Query")
' TO DO: Turn normal error handler on when this condition is finished.
On Error GoTo 0
where = Null
where = where & (" AND [IDTrans]= " + Me![Combo2])
where = where & (" And [IDTransPd] = " + Me![Check7])
Set QD = db.CreateQueryDef("Search_Query", "Select * from qryTransWork " & " Where " & Mid(where, 6) & ";")
If DCount("*", "Search_Query") <= 0 Then
MsgBox "No Records Found"
Exit Sub
End If
Forms!frmTransWork!sfrmTranscriptionistsPd.Form.Re cordSource = "Search_Query"
End Sub
I'm getting a type mismatch error on where = where & (" And [IDTransPd] = " + Me![Check7]) so I'm obviously referencing the check box incorrectly but not sure what to do.
Thanks
