Modules & VBA :: Access 2013 - Invalid Use Of Null Error 94
Jun 16, 2013
The following code works fine until it gets to last record, then it give me Error # 94 Invalid use of null. I have searched all of my code and null is not in the code.
Code:
'--------------------------------------------------------
' Goes to next record
'---------------------------------------------------------
Private Sub cmdNext_Click()
On Error GoTo err_handler
' DoCmd.GoToControl (txtNameL)
' DoCmd.GoToRecord , , acNext
Private Sub Form_Current() Dim strTime As String Dim strHour As String Dim strMinute As String If (CollectionTime.Value) = "" Then MsgBox CollectionTime
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 have these code to auto generate member number but the highlighted line generate error 94 - invalid use of NULL:
Private Sub cmdGetNumb_Click() 'On click of button a new Member Number is generated and 'focus is moved to tFName field. Me![nMembNum] = NewMembNum() Me![tFName].SetFocus 'Prevent accidental click Me![cmdGetNumb].Enabled = False
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)
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
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#));
I have found the error leads to this line but how can i stop the error?
Run-time error '94': Invalid use of Null.

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:
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 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 use access occasionally . How to find out why the Invalid Qualifier error keeps occuring. This is the code, and I've highlighted the line where it says its invalid qualifier:

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.

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 am using VBA in Access 2013 to make a PowerPoint presentation using data from the access database. know if it is possible to use Access VBA to create a button in the presentation that runs a procedure itself?
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!
I need to make a copy of a pdf document that the user identifies in a "hidden" folder that is associated with my backend database. how to code this. I am using Access 2013.
