Modules & VBA :: Checking If Data Entered In Form Field Exist
Jan 17, 2015
I want to check if data entered in a form field is existed
The form is bounded to a table
I used this code
If DLookup("Telegram_Number", "tbl_Violation_Of_Building", "Telegram_Number Like " & Forms!frm_Add_Violation_Building!Telegram_Number) Then
MsgBox ("number existed")
Me.Telegram_Number = ""
Else
End If
everything is ok but if the data is existed the database show the message and clear the field but i'm getting a Run-time error
'-2147352567(80020009)': the macro or function set to the beforeupdate or validationRule property for this field is preventing [ISF] from saving the data in the field
I guess the problem because the form is bounded to a table so he will save automatically
My solution is to unbound the fields and save the data via vba but is there any solution with a bounded form???

Hi
I have to rethink and change the way of display in my form.
I have a form bound to ID.
I want to show 2 fields if they contain data, otherwise hide them
How do you do that?

I have a form with a number of entry fields and after a button is clicked I write to an MS Sql datatable. Everything works fine as long as I put a value in each field. If I do not put a value in one of the fields the sql does not run and the record is not added / updated in the database. I have tried checking the length of the data in the field using
Ent_Length = Len(tb_TagDesc)
or
Ent_Length = Len(tb_TagDesc.Text)
or
Ent_Length = Len(tb_TagDesc.value) but nothing shows.
I am using Access 2007, 32 bit Windows 7

I have a form that contains two text fields i.e.; [Scat_text] and [STyp], which each can be changed by the users. I would like to combine the results of the two fields together and validate if the results exists in a query. What would be the best way to accomplish this?

The following code doesn't check null condition in Scannedby field. The scannedby has text data type. The code gives me all the data where scandate=20130722 but doesn't check that scanned by can't be blank.
Code:
rs.Open "select count(*) from BatchTBL2 where scandate=20130722 and scannedby <> null", cn, adOpenKeyset, adLockOptimistic
j = rs.fields(0).Value

I have a field 'Payment Types' with values (Cash, Cheque, Debit/Credit Card) and a field 'Payment Received' which is Yes/No.
When putting the order through the user selects the payment type and ticks a box if payment has been received.
On a report for delivery drivers, the owner wants it simple for the driver... he wants all the payment types listed with a checkbox next to each one, then wants the appropriate box ticked if payment has been received.
So I need something on the report (or underlying query) which ticks the appropriate box, i.e.
If payment received = true then payment type checkbox = true.
Or should I put the payments into a separate table with both fields so multiple payment types can be marked as paid?

I have a form where the user can add as many rows as he wants - it's usually only 1 or 2 but that's not the point.When he has finished editing he clicks a Save and Exit button.In here I want to save data from the last row he has entered. I have this working but only if the cursor remains on the last row or on the 'new' record row. If he manages to, say, put his cursor on the penultimate row then I save the data for that.
eg.
Col1.........Col2..........Col3..............Col4
AA...........AAA...........AAAA.............AAAAA
BB...........BBB...........BBBB.............BBBBB
CC...........CCC...........CCCC.............CCCCC
DD...........DDD.........DDDD.............DDDDD
EE...........EEE............EEEE.............EEEEE
NEW LINE
So I for instance want to save Col3 on the last line filled in. Lets say the control is called Col3 then
If the cursor is on NEW LINE I have got the code so that
Me.Col3 "EEEE"
If the cursor is on the last line (the 5th) I have got the code so that
Me.Col3 "EEEE"
If the Cursor is on the first line i get "AAAA", "BBBB" for the 2nd etc. How do I always pick up the last line?

I'm trying to write some Code with the target to take a value from a textbox (out of a form) and a pregiven value (in this case = 2) and enter them in a new record in a table. But only if there is not already a record with the exact same combination of these to values. When done, the same button should proceed you to the next form (but this code is not already implemented in the fragment below) even if no values are added because they already exist in this combination.
Code:
Public Function GetID_PatientStudiesGroup&()
GetID_PatientStudiesGroup = [Forms]![frm_PatientStudiesGroupTZP]![ID_PatientStudiesGroup]
End Function
Private Sub BPRS_T1_Button_Click()
Call GetID_PatientStudiesGroup&
Dim strSQL As String
[Code] ....
As you can see, I tried to use a function to refer to the value out of the form, because I didn't find out how to refer to a form in an SQL Code.
Just to give you a better overview: The table where the information should be added is named "tbl_PatientStudiesGroupTZP". The form where you find the Textbox "ID_PatientStudiesGroup" (with the value I need to transport) is named "frm_PatientStudiesGroupTZP". Every part (except the WHERE NOT EXISTS part) worked perfectly for itself, but not when thrown together.

I am fairly new to access but so far I have been able to get what i need from it, until now. I am trying to find a way of comparing two sets of data to find out an employee's average productivty.
Table 1 -Hours Worked (by day)
- contains 'name' 'date' and '# of hours' worked
- an employee would enter the hours here on a daily basis
Table 2 - Contracts Keyed (by month)
- contains the number of contracts worked that is derived from seperate system
- this is entered on a monthly basis (so for example: John keyed 30 contracts for the month of January)
- the system i am pulling this info from does not have the ability to pull a daily count of contract per employee, only a range of dates and it then provides the sum for that range (unless I ran a query for each day, for each employee which would take me hours)
- employees dont have access to this system to enter their own # of contracts keyed on a daily basis.
- for entry, so far i have just been putting the first of the month and then the # of contracts.
In a nutshell, this is the calculation I am trying to create:
(Sum of "# of hours" for the month) / (total "# of contracts keyed" for the month) = employees average hourly productivity.
I have tried to do this with various types of queries and reports but with no luck, I get a prompt saying that access can't compare the 2 fields.
Is there a way to compare the data that is entered daily with the data i would enter monthly?

How does one cause certain data to appear in another field based upon the data entered in another field.
For example: I enter in the field the word "Carrot" in a field called food and the word "Orange" appears in the field color. And then if I enter the word "Beans" in the field food then the word "Green" appears in the field color.
Thanks for you help in advance.

I am wanting to update data in one field which is being pulled in from another table based on an entry in another field in a form
Attached is the database. In the sales form I want to enter a customer ID which will then pull in the customer name from the customer table and put it in the Customer Field in the sales table.
I know I am duplicating the data by having customer name in both tables which is bad database design!

I'm trying to get a spell check to work on a text box on a form. i've got it popping the spell check window after the box has been updated but i'd prefer it to just highlight the errors in red, rather than pop the spell check box. another problem i'm having is when it's finished spell checking the box it moves the form back to the first record. this is the code i'm using.
Code:
Private Sub txt_notes_AfterUpdate()
If Len(Me!txt_notes & "") > 0 Then
DoCmd.SetWarnings False
DoCmd.RunCommand acCmdSpelling
DoCmd.SetWarnings True
Else
Exit Sub
End If
End Sub

My Edit info form has several fields. The two of interest are:
Filestatus - text - open or closed
Dateclosed - date format
When the file is created, the filestatus field is set to "Open". What I would like to do is when a date is entered into the dateclosed field, automatically change the filestatus to "Closed".
Any suggestions?
Thanks in advance.

I work for a voluntary organisation in a hospital environment. Older patients coming into A&E will get sent a letter from us offering help.
We send out about 3,000 letters a year and have just over this number of records on our simple Access 97 database.
The problem I have is when we enter data using a Form in the field Address Line 1 if we have sent a letter to this address before I want somehow for the program to inform me of this. However, I do not want it to stop me from entering the same address again so I can't use the No Duplicates option. The reason being, we may have sent the patient a letter six months ago in which case we would want him to receive another but if we only sent him a letter say 3 weeks ago then we wouldn't send him another. Alternatively, his wife may now be a patient and will get sent a letter.
At present we look at the admissions list, sort our table into Surname order and check if they have been sent one previously, however this is very time consuming and would value anyone's thoughts.
Unfortuantely, I can't program so tend to use the design features and wizards of Access 97
Does this makes sense?
I appreciate the time any of you may take in answering this Thread. As you can see I am a newbie to this. Thank you in advance.

Hi,
I am currently building a stock control system in access. I have a form with which the user selects a stock item from 3 combo boxes (stock name, stock weight and stock grade). The combo box links to a table of stock items. A stock item is made up of a name, weight and grade (all separate fields in the stock items table).
I wish to setup the form so as the user selects the stock name from the first combo box. Based on the value selected by the user, the appropriate stock weight(s) assoicated with that stock name will be displayed in another combo box.
Basically, I wish to take the result from one field in a form and apply its result to a query(?) in another field so as to filter(?) my result accordingly.
Hope that makes sense. Any suggestions?
Cheers

Hi all..
This is my first question posted on this site. I have created a survey with questions to be answered. The database is already populated with records of the people's names who were getting the survey. What I need is when the data entry clerk brings up the customer's name on the form, is that they are forced to enter the surveys answers for certain questions before they click the "Save" button. The answers are set up as radio buttons on the form (ie Less than 6 Months, 6 Months, 8 months and 1 Year).
Not sure if a Before or AfterUpdate macro is needed?
Any suggestions would be appreciated. Please email me directly if you have code.
Thank you

I have a form where users enter data in various ways - combo boxes with drop down selections and text boxes where users manually enter some data. I also have several text boxes that return "answers" based on calculations from user entries mentioned above. The form is bound to a table where all the entered data is stored. I'm having trouble saving the calculated information to the bound table. It's easy in all the non-calced boxes, I just put the column name of the bound table in the control source, but in the calculated fields, I already have the formula in the control source. How can I identify the proper column to save the data in this case.
Thanks!

Hello again,
I have three questions this time 'round:
1. I'm in need of some way of preventing a user from opening form B unless he has entered information in form A.
Right now it is possible to open form B without entering data in form A (form A being the date/time info and form B being the case technical info) due to which a record is created for clientnr 0 (which should be a non existing client). Querying for clientnr 0 from time to time and deleting those records is easy enough, but who knows what kind of relevant data could be stored accidentally in a record that doesn't belong there.
This happens by the way, even though referential integrity is enforced throughout the dbase. Maybe I should say, because of that. I want to keep it that way of course to prevent orphans roaming around. But having orphans for clientnr. 0 is also not a good idea.
2. What is the wiser thing to do: keep all information concerning one case for one client (date/time info per case, techinfo per case, maybe even products sold info per case, payment info per case) in one table and have the data needed for each thing entered in seperate forms, or have all data split up into seperate tables like I have now. One for clients, one for dates and times, one for the technical info for that case etc.... ?
It is starting to seem a bit ehrm... useless to have all that data for one case floating around seperate tables. I don't know... it seems so much more complex (having to create multiple relations, multiple PK's per table etc.).
Where do I draw the line? For example the image attached (relationship2.jpg): now I have one PK in the table holding the clients (clientnr), two PK's in the table holding the case date/time info (clientnr and casenumberdatetimeinfo), three PK's in the table holding the techinfo (clientnr, casenumberdatetimeinfo and casetechinfonr). And what's next? Four PK's in the table holding the sold productsinfo? Five PK's in the table holding the invoice info? And what about the relations between those tables? Right now I can still comprehend.... but when I start thinking ahead, I'm starting to get dizzy. So some advice on this would really be highly appreciated.
3. Which build up of the relations between the tables in the dbase is better? The one in relationship.jpg or the one in relationship2.jpg?

I am not sure where this thread should be in forms or queries. I have database which has 3 linked tables by ID in each table. I have built a query on the 3 tables, then created the form.
Now when I enter data on the form and save it, when I open up the said form again , the data is not there. Yet the data is in both the table and query
If I only use 1 table, then there is no problem. The record source for the form is the query, and the query uses the 3 tables.

I have a form that the user enters employees daily duties. I have code to run sql after the BoxNum field has data in it. I want it to look at the BoxNum field and the dropdown box for the task to see if the entered box number has already been completed for the task selected on the form. Here is what my code looks like now. The code runs but gives me the msgbox no matter if it is a made up box number and I also get a syntax error 3075.
Code:
Private Sub Text13_BeforeUpdate(Cancel As Integer)
Dim rs As DAO.Recordset
Dim strSQL As String
