In the previous posts of this tutorial, we have seen How to Create a database in VB 2010 and then we have added button control in VB Database in it, which was quite an easy job.
Quick question, new to this site, new to programming especially.
I'm trying to Select data from Sql Server and then update it while it's still a recordset.
if data of room 1 changed then software automatically update the info of that room in its database.
So, for students and also for freelancers its essential that they must have full command over database, and in order to understand today’s post its also essential that you must read the previous two posts of this tutorial.

I also work as a freelancer and did many projects related to programming and electrical circuitry.
i am trying to edit a record that i just saved into the databasebut the code I have been using has been giving me some errors " run time error '3251': current recordset does not support updating. You can overcome this by using an array to keep track of changes not yet posted to your local recordset and only do a requery when the array gets to a certain size. If you're really trying to help them, you have a responsibility to see that you're not giving them wrong information. I apologise for the "mistake" but object to the term "howlers".
This maybe a limitation of the provider,or of the selected locktype " I am using the code below for my update: Set rs = New ADODB. Open "Access", Con, ad Open Forward Only, , ad Cmd Table If Not txt User Number. Also, the Filter method works better for me in this context than the Find method.

I don't want to update the actual table with the data.... ("First Name") and I want to add a string to it, for example "MR" This is how I go about it You should show all your code to make it easier to help you.
From what you DO show - an obvious fix is to use your str variable. Open 'populate the new recordset with the original values rs Updateable.
