Runtime error 3021- Either BOF or EOF is reached , unable to resolve this

ruvi

I am getting runtime error 3021 - Either EOF or BOF is true or the current record has been deleted.....
I have 2 combo boxes in a form- One for the client and the other for the project.
When the form loads, the client combo box gets populated with all the clients.
When a particular client is clicked, the project combo box gets populated with all the projects corresponding to that client.
So far, so good. Now when I click a project in the project combo box, I get this runtime error.
Been stuck here for 2 days without a solution. Please help.

This is the code I have

 Private Sub Form_Load()
 
    Call SetupADO

    Call SetupClients
 
End sub
 
Private Sub SetupADO()

Hope u guys can bail me out.

Dear need not to post entire code here just put the code which have th error
use

Expand|Select|Wrap|Line Numbers

 if Rs0.eof or rs0.bof then

'msgbox "No mor records found"

else

' put ur code here

end if

where Rs0 is the Recordset
try it
Good Luck

Have you tried stepping through the cboProjects_Click routine, checking the effects on arsProjects at every point?

Also, I find it odd how you are doing the "If BOF and EOF then ReQuery and MoveFirst" just before the end of this code. Just prior to that, you have either created or requeried arsProjects. So if this condition is true, doesn't that mean the dataset is empty? In which case, another requery doesn't seem as though it will help.

if Rs0.eof or rs0.bof then

'msgbox "No mor records found"

else

' put ur code here

end if

Wouldn't this prevent your code ever being executed? Presumably we'd be starting at the beginning, so BOF would be true.

Thanks for ur time guys.

Strangely I get the runtime error only while clicking on the first project in the combobox, and not while clicking the second or third or fourth project or any subsequent projects. Why is this so?

Also, after Recordset.requery, I am able to print all the records(projects) in
the recordset. It means that the recordset is not empty, isn't it? Then why is it that I am getting the error only while clicking on the first project in the combo box. Is it due to the parametrized SQL statement that I am using to access the projects table?
Help please...

sudheernis

this is the solution to runtime r.eof or r.bof here r is the recordset

Expand|Select|Wrap|Line Numbers

 do until r.eof

            if r.eof=true then

                    r.movelast

             end if

      r.movenext

loop

for bof

Expand|Select|Wrap|Line Numbers

 do until r.bof

         if r.bof = true then

                 r.movefirst

          end if

 r.moveprevious

loop
