OpenArgs Always Null Value
Nov 6, 2007
Hi Guys,
I have 2 form (Form1) is a log-in form, (Form2) is the Data Entry. After Authenticating the user on Form1 I used DoCmd.OpenForm "MyFormName", , , , , , varUserName, then open Form2 with following code on OnOpen event:
If Not IsNull(Me.OpenArgs) Then
Me.txtUser.Value = Me.OpenArgs
Me.Requery
Else
MsgBox ("Null")
End If
but it always shows the msgBox "Null"
What seems to be the problem with this?
Thanks in advance.
Jeff

I've read about 50 posts regarding passing a value from one form to another, and I Just don't get it!
I have a table of zipcodes which I use to autofill city and state fields. The Zipcode is entered into txtCoZip. If the zipcode is in the table it autofills, but if the zipcode is not in the table, a form opens to add it to the table. OpenArgs seems to be the answer to this, but I can't quite follow it all the way through. This is the code I'm using to open the form:
DoCmd.OpenForm "frmAddZipcode", OpenArgs:=Me.txtCoZip
This is the code I'm using on the onOpen event of frmAddZipcode:
If Not IsNull(Me.OpenArgs) Then
Me.ZipCode = Me.OpenArgs
End If
I'm getting an error "you cannot assign a value to this object'.
What am I doing wrong?
Thanks,
Sup

Hi all,
I have a form (sub_Main) that opens and has an openargs value (Department) from my main form when user clicks on a cmd button. However, if I were to go back to my main form and click on another department the openargs value is not passed along. I have tried using Me.Refresh under LostFocus but it doesnt seem to work.
What is causing the openargs value from updating? Any help?
Thanks!

Why do I get and error with this code? It says the openargs is null when I run it
Private Sub TXT_SALESMAN_NUMBER_DblClick(Cancel As Integer)
Dim StCustNumber As String
StCustNumber = Me.TXT_SALESMAN_NUMBER.Text
DoCmd.OpenForm "Frm_Slm_Name", acNormal, , , , , StCustNumber
End Sub
Private Sub Form_Open(Cancel As Integer)
Dim StCustNumberSub As String
StCustNumberSub = Forms![frm_slm_name].OpenArgs
DoCmd.GoToControl "Salesnumber"
DoCmd.FindRecord StCustNumberSub, , True, , True, , True
End Sub
Thanks

I have a calling form with the following code
Dim strTbl As String
Dim strTitle As String
Dim strSQL As String
strTbl = Me.cboRep.Column(0)
strTitle = Me.cboRep.Column(1)
strSQL = "SELECT tblSupp.SuppName, tblCurr.CurrName, * " _
& "FROM tblCurr INNER JOIN (" & strTbl & " INNER JOIN tblSupp " _
& "ON " & strTbl & ".SuppID = tblSupp.SuppID) " _
& "ON tblCurr.CurrID = " & strTbl & ".CurrID;"
DoCmd.OpenReport "rptList", acViewPreview, , , , strSQL & "," & strTitle
On the Report's OnOpen Event I have
Dim strStr1 As String
strStr1 = Left(Me.OpenArgs, InStr(Me.OpenArgs, ",") - 1)
Me.RecordSource = strStr1
And on the Report's On Activate Event I have
Dim strStr2 As String
strStr2 = Mid(Me.OpenArgs, InStr(Me.OpenArgs, ",") + 1)
Me.txtTitle = strStr2
This should work but it doesn't. The error states that the SQL statement
was not found. Of course, without the second concatenated argument
and Me.RecordSouce = Me.openArgs everything works fine.
Can anybody see where I have gone wrong
Thanks

I have used the OpenArgs method to pass a parameter to another form, but I now need to psss two parameters, and I am not sure how to do this.
On Error GoTo Err_CmdOpenForm_Click
Dim stDocName As String
Dim stLinkCriteria As String
stDocName = "frmName"
DoCmd.OpenForm stDocName, , , , , , Me.Text0 'need to pass another
'Parameter Me.Text1
Exit_CmdOpenForm_Click:
Exit Sub
Err_CmdOpenForm_Click:
MsgBox Err.Description
Resume Exit_CmdOpenForm_Click
And on the Load event of frmName, Me.Text1 = Me.OpenArgs 'and Me.Text2

I'm making a DB for invoices.
I'm trying to make it so that an item can be returned by clicking a command button (cmdReturn) and a form (Returns) will be brought up with the ItemID field already filled in. I'm trying to use OpenArgs but am having problems. At the moment i've got
In the command button:
Private Sub cmdReturn_Click()
Dim varItemID As Integer
Me.Refresh
varItemID = Me.txtItemID
If Not IsNull(varItemID) Then
DoCmd.OpenForm "Returns", , , , , , varItemID
Else
MsgBox "No valid item to return", , "Error"
End If
End Sub
And in the Open Event of the Returns form:
Private Sub Form_Open(Cancel As Integer)
Dim varDCount As Integer, varOpenArgs As Integer
varOpenArgs = Me.OpenArgs
varDCount = DCount("ItemID", "Returns", "[ItemID]= 'varOpenArgs'")
If varDCount = 1 Then
DoCmd.GoToControl (Me.txtItemID)
DoCmd.FindRecord varOpenArgs, , , , , acCurrent
Else
DoCmd.GoToRecord , , acNewRec
ItemID = varOpenArgs
End If
End Sub
I'm getting this error message:
"Run-time error '94':
Invalid use of Null"
And the line in bold above is highlighted with the mouse over message saying "Me.OpenArgs=Null"
If an item already has a Return entry, I want it to go to that entry instead of making a new one. ItemID is the primary key in both tables, linked in a ONE TO ONE relationship.
Any help is appreciated, please ask questions if something's not clear.
Joe

Hi
I have a form with some tabs. Each tab has 2 subforms, of which the 2nd subform is always the same (call it SubformB).
I had it set up before so that the SQL query to run is passed in the openargs property to that that form and this works well.
However, on a tabbed form, each tab opens up Subform B as soon as the page is loaded. Is there a way to pass openargs to SubForm B on each of the tabs so that they all run different SQL queries even though they are essentially the same form ?

Is it possible to send several form's OpnArg as Array ? Now I'm using a long text string including || as divider so I can split them later into Array.

The access website says there is a way to use the open arg in combination with the FindRecord method to open a form up to a specified client name. I'm trying to have a macro that asks the user what student they are looking for and then takes them to the form with that name. The reason I can't use a query or something else is because I have macros on the form page that I want them to have access to.
So my question is this.
What's the best way to make a macro that will
1) ask the user for a name input
2) open an already made form
3) take them to a specific record based on the input name
I tried to use something with InputBox and DoCMD.OpenForm but I'm running face first into a wall any time I tried to combine the two.

Hi all,
I seem to have encountered a strange problem at work.
I declared a public variable for user department. The user selects his department from a Log On form and if the password is correct, he opens another form with the department variable passed on in openargs.
All of this works fine in access2k but upon testing with 2003, the openargs somehow do not seem to be being passed on. Maybe I am being dense somewhere but it is kinda puzzling for me.
I am not using access's security for users and groups because I am trying to reduce the complexity of the whole project (I wont be around to maintain it next time).
Any help rendered is greatly appreciated!

Ok heres the situation, Ive had to edit a piece of code that worked fine filtering but wouldnt allow me to refresh a subform on the main search form. Now im using OpenArgs to pass the Selected bike ID to a popup form. This bike ID should then be used to filter the pop up form. But i get error 2001 (You cancelled the previous operation) when the code is run.
The Code follows:
Private Sub cmdSell_Click()
Dim stDocName As String
Dim stLinkCriteria As String
stDocName = "frmSubSell"
DoCmd.OpenForm stDocName, , , stLinkCriteria, , acDialog, Me.frmSubBikes!BikeID
Me!frmSubBikes.Form.Requery
Private Sub Form_Open(Cancel As Integer)
Dim SearchStr2 As String
SearchStr2 = "[BikeID]= " & Chr$(34) & Me.OpenArgs & Chr$(34)
Me.Filter = SearchStr2
Me.FilterOn = True
End Sub
Thanks, Sci

I do not understand what is happening here. I have foll0wing line in a calculated query field:
m: Switch([EmpID]<5,1) ' run Query 18 in attached example, A2007/2010
this produces 1 for all EmpID<5 and Null for all other EmpID's. All as expected.
But if I do this:
m: Switch([EmpID]<5,1,[EmpID]>=5,Null) ' run Query 19 in attached example
then the entire column is set to Null

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].

intCounter = 0
Dim rs As ADODB.Recordset

Hello all,
A bit of a weird one, I've got a query and the criteria for showing records is that one particular field is null. However the query is showing records with the values in the field chosen for the Is Null.
Not sure why this is happening, has anyone come across this problem before?
Thanks.

I think the title pretty much sums it up....
I have a query where data is first sorted by user input; first field's criteria: [fieldname], then by another field's criteria: Is Null.
I know there are records containing null values in the second field, as I have run a select query with the criteria: Like "*", to make sure they are null, and not zero-length-strings.
The query is refusing to return any results...
Any ideas?

I personally believe 'NULL' should be banned as a possibility entirely. :eek:
It has been pounded into my head that 'NULL' is not the same as 'EMPTY' or 'ZERO'; and that it literally means 'NOT KNOWN'. Now consider a contact database that has a field for lets say Apt# or Street Direction such as N or S or ?? as an example. There are many, many instances where these fields would be left blank or empy: NULL | NOT KNOWN. When in fact the situation is known: the object has no such attribute; and in query or some other form of program logic the venerable NZ(subject, response) function may be used which would replace the NULL with a value. Or program logic and or error trapping would be used to handle such occasions. Which is an absurd waste of time and talent IMHO.
Therefore, if there is no applicable attribute to enter (something known) why not say so with 'N/A'? Else what we are saying by using 'NULL' is that we are building a dataset containing data that cannot be known. Kind of like saying
This statement is FALSE

When filtering by form I suddenly get the words: Is Null / Is Not Null appearing in the drop down menu of all fields.
I can then no longer filter at all?
This is carried over to filter by form too!
When I export, or cut and paste the records into my backup database (filters working ok before I do!) the same thing happens!
Can anyone help….please?
