The basic idea is that I need to insert a record into a table and then return the Key field so that I can use it to populate another table. This was working just fine for a while, then it stopped and naturally I can't think of anything I did to make it not work. I get an Invalid Use of Null error at the bolded step.
Dim SQL As String
Dim SpecID As Long
Dim VerifySpec As Variant
' Check for empty strings
If Len(Me.txtNewPartNumber & vbNullString) = 0 Then
Response = MsgBox("Part Number cannot be blank.", vbExclamation, "Missing Data")
Exit Sub
End If

I am struggling trying to execute a function inside a Form_current event to display some stats.
The Function is this:
Code:
Function FlightsByAircraft(Aircraft As Long) As Long
Dim rst As DAO.Recordset
Dim dbs As DAO.Database
Dim str As String
str = "SELECT * FROM tblFlights WHERE AircraftID = " & Aircraft
[Code] ....
The code for the Form_Current event is this:
Private Sub Form_Current()
txtStats1 = FlightsByAircraft(Me.AircraftID)
Very simple. Well, the problem is when I move to a new record, a error message comes up: "Run-time error '94' - Invalid use of Null". It is because the AircraftID is not populated at that time. I tried to insert in the function code something like that:
Code:
If IsNull(Aircraft) then
exit function
else
.... (the DAO.Recordset code)
but it doesn't work.

It might be an easy one but I just wasted the past hour deciphering through my code in order to solve the run-time error '94' that I'm getting when trying to execute the following code:
Code:
Private Sub cmdUpdateDates_Click()
'###################################
'This sub aims at combining the timesheet date and the start and end time into the fields [Start Time] and [End Time].
'###################################
Dim intCounter As Integer
intCounter = 0
Dim rs As ADODB.Recordset
[Code] ....

The following query runs without issues.
SELECT Payment_Mth, CDate(Payment_mth) AS Expr1
FROM Table1
WHERE (((Payment_Mth) Is Not Null
And (Payment_Mth)<>"Does not apply"
And (Payment_Mth)<>""));
I get a set of data along the following lines
September 2007 01/09/2007
October 2007 01/10/2007
September 2007 01/09/2007
etc.
which is what I want.
However, when I try to filter to show only a particular date, I get an error
SELECT Payment_Mth, CDate(Payment_mth) AS Expr1
FROM Table1
WHERE (((Payment_Mth) Is Not Null
And (Payment_Mth)<>"Does not apply"
And (NBReferral.Payment_Mth)<>"")
AND ((CDate(Payment_mth))=#01/10/2007#));
An 'Invalid use of Null' message is displayed.
What am I missing, here?:confused:

I am developing a database for my company which will produce reports based on data entered on various forms.
When the report opens, I would like its name to dynamically change to include the site, the client and their reference number. Although I know very little VBA, from searching this and other forums I have managed to get this to work on other forms.
On a different form, I have managed this by giving the form the caption "Caption" and then running the following code on load:
Reports("ItemisedQuoteFromQuoteFromViewSalesEnquiryFromSearch").Caption = "Our Quotation Ref: " & [StaffInitials] & "/" & [QuoteEnteredBy] & "/" & [QuotesJobsSalesEnquiryRecordNumber] & " - " & [ClientDetailsName] & " reference " & [JobsClientJobNumber]
Which will give the report a title along the lines of: "Our Quotation Ref: AB/CD/123456 - Client Name reference 987654".
On the report I am struggling with the code is:
Reports("MWUPropertyAssessment").Caption = "Property Assessment for " & [SiteDetailsAddressLine1] & ", " & [ClientDetailsName] & " reference: " & [PropertyAssessmentClientJobNumber]
However all this produces is "Property Assessment for , reference". If I try entering just "[SiteDetailsAddressLine1]", "[ClientDetailsName]" or "[PropertyAssessmentClientJobNumber]" I receive an Invalid use of Null error message.
If I create text boxes on the report for [SiteDetailsAddressLine1], [ClientDetailsName] and [PropertyAssessmentClientJobNumber] they are filled with the correct information so I know that these fields are not blank.

I am using Access 2007 and are a newbie.
I am using the following code (Sendobject) to create a PDF of a report and send it via email to a customer's email address.
Private Sub EmailWorkOrderQuote_Click()
On Error GoTo Err_EmailWorkOrderQuote_Click
Dim stDocName As String
Dim mFilename As String
Dim mEmailAddress As String
[Code] ....
It works fine except that the I want to to able to utilize the ability to send the email with either both the CC and BCC or either or neither as well.
I have a table called "My Company Information" that contains the email addresses for the CC and BCC. If I have values in these fields, everything works great! If I have no values in either of these fields, I get "Invalid use of Null"....
I want to be able to use either both CC and BCC, either CC or BCC, or neither used and it still work.

I am regularly getting the error "There is not enough free memory to update your display, close unneeded programs and try again"
Access 2013 on a windows 7 machine with 4 processors and 24GB total RAM.
Today I have 14 GB free memory (unbelievable! my first laptop had 136 MB total memory!) when I got this error (Access using 38MB) which makes me believe its not a system memory issue but to do with how much (or quickly) memory is allocated to Access.

I use before insert code procedure to insert default value for one, or more fields in row. It is normal to have these fields are disabled. This event occurs when you try to enter a value in any another field in a row. However , when I finish entering the field going to the event before update regardless and trigger a validation of all fields in a row. I am not leaving from row , I want to go further input in other fields.How to insert default (calculated) values in new row.

I need to save a single record (preferably the current record) as a PDF. I have created a form for my boss to calculate bids. He wants to save each record individually as a PDF to upload into our service software program to attach to client files. I can save a selected record as a PDF if I print the selected record first. We need to eliminate having to print it first as it is just a waste of paper and an unnecessary step. I am kind of thinking that VBA and attaching that to a control button on the form is the way to go, but I am new to writing code and I am completely confused!
