Is it so hard to go back and preview your post to make sure it reads exactly as you expect?

It's right next to the Post Message button.

Sarcasm and apologies are not necessary. I was merely letting you know a way of increasing your chances of receiving help.

I have been posting message since a week. I didn´t take time to look at every button... That´s all.

I thought that too, but a simple " Sigh | :sigh:

hum..." seemed not to be enough because you felt posting a new message...

However you didn´t "merely letting [me] know a way of increasing [my] chance of receiving help. "
I "paid" for each person who did that. You didn´t need to say "is it so hard to..." just give me the information. That´s all. There is no need of being haughty with me.

The word "hum" is meaningless when no context is provided.

Why would you expect to receive help when over half of your code snippet cannot be read? Format your code properly, and double-check your grammar, before committing your posts. You'll receive much more help as a result.

I know that i did not post the message properly, i should have done a preview before sending it, there is no need to argue about this, i agree with you.
However this is a useless conversation, I will do a preview before posting a message that´s all...

Usually, Windows applications relies on the Common Dialog Library's Print Dialog Box to let user browse for the available printers.

That's no excuse for acting like a whiney brat. If someone with experience sees your question, they will post an answer. If you post over and over, they will get annoyed, and might ignore your question. So be patient.

We already did, he seems unwilling to debug or try anything to identify the problem.

The issue is not the NULL recordset, but a combination of dodgy error handling and a refusal to look into why he is getting NULL from the query.

I think this is a reposting of your previous query. Is the earlier thread not providing you any solution. I think it is the same problem. Your recordset is not returned instead just NULL is there so you end up with an Access Violation Error.

Have you debugged the application after necessary changes were made to it?

He's basically ignored everything we suggested in the original question.

I will not help anymore as he could find the problem in 2 seconds using the debugger.
