Access Vba Runtime Error 3075
for this topic, I dug a little deeper and figured out a reusable solution. It is posted below as a contribution to the community of developers. Note: the language is VBA. Public Function hasNoValue(myExpression As Variant) As Boolean ' Author: Roger G. Abbott Date: 11-Jan-2013 ' Copyright: Please feel free to reuse in any way you see fit. ' ' This function returns True if the expression will trigger error 2427 ' ' Background: When access vba runtime error 3141 a Form's control is linked to a recordset, ' and that recordset is empty (e.g. a table with no records in it yet.) ' Then any reference to that control's value will trigger the following error: ' Run-time error '2427': You entered an expression that has no value. ' There is no test for this in the VBA language. This routine provides such a test. ' ' Note that the message is really saying that the expression has no Property with the name "Value"! ' This routine is faster than looping through the property list in VBA. ' ' Example: ' Dim myVariable As String ' or Long or Date or anything returned in my recordset... ' If Not IsEmpty(myForm.myControl) _ ' And Not IsNull(myForm.myControl) _ ' And Not hasNoValue(myForm.myControl) _ ' Then ' myVariable = myForm.myControl.Value ' Else ' myVariable = "" ' The value I want to assign if there IS no value. ' End If ' ' Dim v As Variant On Error GoTo Err_Handler hasNoValue = False ' not true unless we see the error! If myExpression Is Nothing Then GoTo exit_Main If IsNull(myExpression) Then GoTo exit_Main If IsEmpty(myExpression) Then GoTo exit_Main ' the assignment statement below will trigger error 2427 if the expression has no value. v = myExpression.Value GoTo exit_Main Err_Handler: If Err.Number = 2427 Then hasNoValue = True

Expression with "No Value" Expert 100+ P: 407 JustJim Just when I thought I was getting my head around Null values.... I have a report with three sub-reports, on each sub-report footer I count how many records in the subreport. No problemo. On the Detail section of the main report, I have a text box which adds up all these counts and shows how many (people) in total. Again, no problems... as long as there is at least one entry in each sub-report. Ahh thinks I, I must trap for null values. Sadly, however, that didn't work either. When I put a breakpoint in and go to the immediate window, I can debug.print the values of the textboxes that do the counting on the sub-reports, except where no people fit the query that feeds the subreports. Surprisingly (to me anyway) when I try to print that one, I don't get the Null I expected, I get Expand|Select|Wrap|Line Numbers Run-timeerror2427 Youenteredanexpressionthathasnovalue Any ideas?
