EOF and BOF Errors

Part of the coding is listed below but when i run this it comes back with EOF and BOF error (Either BOF or EOF is True, or the current record has been deleted; the operation requested by the application requires a current record)

Error occurs on the line override = rsc("override") am new to programing and not sure where i would need to fix this error or what i would have to do.

The person we had do this is no longer working with us and the program to best of my understanding was built using Visual Basic 4.0

Would appreciate any help that you may give me.

re: EOF and BOF Errors

It looks like record with this name wasn't found
Put this code before line that gives you an error which just checks if actual record was found and exists if not.
[PHP]
IF rsc.bof and rsc.eof then
Set rs = Nothing
Exit sub
End if
override = rsc("override")[/PHP]

I am not sure of your business rules but it might be the case where user hits an update button when actually needed insert. If you have insert button you can call it instead from update button like this:
[PHP]
IF rsc.bof and rsc.eof then
Set rs = Nothing
call InsertButtonName_click
Exit sub
End if
override = rsc("override")[/PHP]

re: EOF and BOF Errors

Hi, thanks for the code you replied us. It seems to have fixed the problem of it erroring out, however, by entering that code, we cannot apply any discounts to the item we are trying to add.

To sum it up, the code you gave us let us insert the new item to the customers order, however we cannot override manually the discount given on a particular item.

Right now we may assume that the employee working on this program has left out some key items to make the prorgram complete, but its hard to say since I do not know how exactly he coded this particular portion.

If you have any other suggestions it would be appreciated.

re: EOF and BOF Errors

I won't discuss the EOF/BOF thing, as Iburyak has dealt with that. As for the rest...

I think you need to pinpoint why the name doesn't match. In this you need to investigate where (or whether) the variable product_name was populated, and why it doesn't match what you expected to find in field [products].[product_name].

If you find that it does appear to match, consider the possibility that the match might be case-sensitive. (I'm not at all certain that is even possible, though).

Also, if I might be permitted a personal observation, I think it is unnecessarily confusing to use identical names for database fields and variables in this way (Eg. product_name). :) I realise you're just trying to take over someone else's unfinished code, but I think that's worth keeping in mind.

And one last point. When posting code, please put [C O D E] and [/ C O D E ] tags around it. (Remember to leave out the spaces I embedded in the tags here, and do a "Preview Post" before submitting, to see whether it worked.)

re: EOF and BOF Errors

Unfortunately I can give you direction and suggestions but you are the one who have to make it work. I’ll try to give you one more advice:

Try to do this:

[PHP]

Set rsc = CreateObject("adodb.recordset")

RestartDiscount:
rsc.Open "select * from products where product_name='" & product_name & "'", strDSN, 3, 1


IF rsc.bof and rsc.eof then
call InsertButtonName_click
GoTo RestartDiscount
End if

override = rsc("override") [/PHP]

What I do here call insert command and then redirect code to start discount update all over again. Now it should find newly inserted record and proceed with discount, if of cause I didn't miscalculate it, due to inability to test. It is only my guess.

Good Luck.
