Err 91 : Object variable or With block variable not set

[nelsonchang]

Dear all,
I wrote the VB code in a "button press event" as below in
which is retrieve data from SQL server and insert the data
into Excel. After that, I would call Excel "subtotal" API
to build a subtotal figures. For first time, it is working
fine. But in the second time, I try to execute the event
again. Whenever it runs the command "Selection.Subtotal
GroupBy:=2, Function:=xlSum, TotalList:=Array(3)", it
always raises the error "Err 91 : Object variable or With
block variable not set". Please advise.
Thanks & Regards

Hi Nelson,

Even for me this looks very much to VB6 code, either you have to change it
to more VB.net I think or else (if it is VB6) I think that it is better to
try to find help for this error in a classic VB newsgroup

Microsoft.public.vb* (there are a lot)

I hope this helps?

Seems to be VB6 code.

I thought here is for VB code whatever which version.

I thought here is for VB code whatever which version.

As the name of this group says, it's a VB.NET group
("dotnet.languages.vb"). The VB1-6 groups can be found in the
microsoft.public.vb.* hierarchy.
