Help Needed With Database Problems; Validation Rule And Image Form

Apr 17, 2007

Hello Everyone,
I am in the final stages of creating a database for school coursework however I am having a few problems with a few features; any help would be much appreciated.
The database itself is meant to manage / keep are record of utility bills, it consists of two tables: Invoice and Company.

Problem 1.
In the Invoice table there are two fields called Date Due and Date Received the data type is Date/Time, how do I create a validation rule so that Date Due must be after 'Date Received' and vies versa?

Problem 2
I want each record in the database to store an image of a scanned invoice, and the main form called Transaction to show a preview image of the invoice. Much of the code I used is borrowed from the Access Northwind sample database, after some initial success I had to redesign the 'Transaction' form where the picture was shown and now I get the error message:
�Run-time error 2135, this property is read-only and cannot be set�
I think I know what is causing the error but I have had no luck fixing it, if someone could help me that would be excellent.

Problem 3
Once I get the Transaction form to properly store and display a preview image of an invoice, I want to add a button that opens the image in an external window(ie MSPaint).
Currently my only success has been to add a button on the form that launches MSPaint (you have to manually open the image in MSPaint.)
Again, if someone could help me sort this out it would be excellent.

Sorry if my problems aren�t clear or well explained.

I have spent many hours looking for answers to my problems in forums, Access help files etc�
My computing tutor has little (no) experience with Access so he has been unable to help, hopefully the people on this forum have the expertise.

I am happy to email you my database if you need it to help me with problems 2&3.

Thanks in ALOT advance

Problem With Validation Rule On Form

Oct 22, 2005

Hello, I'm having difficulty with a validation rule in a form. I have a numeric field I want to limit users to entering a number between 1 and a variable second number. The second number is the number of records in the table. So if the table has 5 record, the user can enter a number between 1 and 5. When the number of records increases to say 15, then the user should be able to enter a number between 1 and 15.

What I have done so far is as follows:

Function MyValRul()
MyValRul = "Between 1 And " & DCount("*", "tblRegion1")
End Function

and in the validation rule option for the field on the form I enter
=MyValRul()

This should returns a value like
Between 1 and 15

But it does not work. I do not get any programming errors but when I attempt to enter a number in the field I get the validation error message even if I enter a number that IS valid.

Any assistance will be greatly appreciated. And please be gentle (i.e. keep it simple and include detailed step by step instructions) I am new to Access and vba.

Data Entry Validation Rule In Form

Dec 7, 2012

What I have:
Table named: clients table
Form named: clients data form

The form has the client information. The client sends me a document. I review the document. If the document has the correct info needed, then I have a field named "Incomplete" that is a Yes/No field in the clients table.If the field is clicked, then I want the next date field to appear and then I can fill in the date that it was sent back to them.If the field "incomplete" field is not checked, then I don't want that date field to appear nor do I want to fill it out.

Input Mask, Validation Rule, Search Form

Dec 1, 2005

I have a form that acts as a filter/search engine -- it inputs criteria into a query, then opens a report based on the criteria/query. One of the criteria options is "Supplier Number", which is to be entered into an unbound text box.

All of our suppliers have 10 digits, usually in this format: A123400000 (i.e. First character is either a Letter or digit, followed by four or five digits, then followed by four or five zeros)

Our system works with ten digit numbers, while the people in the dept are used to just typing in "A1234" assuming the zeros are irrelevant.

How do I create a validation rule or input mask where a user can simply type "A1234", then it will return zeros for the remaining of the ten required characters?

I realize the usual response to these type of simple question is "Search the Threads", but I have done so already and still don't have an answer!

Cancel Validation Rule Message Boxes On Closing Form

Oct 26, 2006

I want to close a form and I am using

Private Sub Form_Close()
Application.Quit
End Sub

as the form opens with the access application window hidden, and I found that the .ldb file didn't close if I simply used the X.

I have a series of fields with validation rules which activate on exit. One of these validation rules is in the box which gets focus when the form opens. This means that I get the validation text error message boxes when I close the form with the X.

If I have started to complete the form, I get a whole host of error messages and validation messages when I try to shut it with the X.

Is there a way of closing the form and cancelling or ignoring all error message boxes. I want the user to be able to close the form if they have decided not to fill it in after all, or have got part way through and want to cancel.

I would really appreciate any help, I am sure this is a very basic question and I should probably be able to find the answer, but I can't and I am very fed up!

Forms :: Validation Rule In Access Form On Unbound Text

Jan 8, 2015

Is there a way to add a validation rule in an access form on an unbound text box. This box is currently doing a calculation of others. If the figure is not between 0 And 0.3125 then I do not want the user to be able to move on. For some reason if I enter "Between 0 And 0.3125" in the validation rule it doesn't seem to do anything. I can only assume its because its an unbound text box. Data attached please see Frm_Input and text box total standard hours.
