I have search into google and a lot of forums about database connectivity and my problem is simillar to other but a lot of things differs.The error that I get is on executeNoQuery() and it's called {"Connection must be valid and open."} Well a lot of things may related to about that.At least now from my re-search I covered all the filds of the problem and still not fixed. So please check my code for (Add new customer) button and let me know where I have mess up.

Sep 18, 2009I am trying to add records from an Access Database into another Access Database using DAO recordset.The VB.NET program would add the records until it hits random stop and error says "Object invalid or no longer set". what would cause this? The recordset contains 7 million records, but it only added approx 6000. Next time i run the program, it would add different number of records again.

Appearance Of The "Object Reference Not Set" Error Message?
Nov 21, 2010I updated from VB2010 Express and Win7(x64) from VB2008 Standard and Win7(x86) and have been tweaking a programme and some user controls I have been using for some years. In the last three days only whenever I open the programme and run it, I get the error message box "Object Reference not set to an insatnce of an object"" three or four times. The programme then runs correctly. If I stop and restart the programme, the error message not reappear. If I then edit code and rerun (or save) the programme, the error message reappears. The error messages do not appear if I run the programme from the EXE file pinned to my taskbar
I have been unable to trap the error message to find out on the stack a clue to the line in the programme that is causing the problem. I do not add controls at runtime and all have been added to the designer at design time.
Error Message "5:Object Is Currently In Use Elsewhere." When Drawing Polygon
Jun 22, 2010I am developing the map tool application in vb.net where user can create maps. I gave the check boxes for show/hide the layers of map like village boundary(polygon), plot boundary(Polygon), roads(Lines), bore wells(points), dug wells(points), schools(points).
I am using the function RedrawMap for displaying various layers of maps as user checked the check boxes. If user click village boundary map shows the village boundary etc on panel control named "picMap".
The problem i am facing is when user check the village boundary layer map shows the boundary but when user check the next polygon layer i.e. plot boundary layer it gives the error message "5:Object is currently in use elsewhere.".
My code is as follows:
Public Sub RedrawMap(ByVal index As Integer)

Asp.net - Display Specific Error Message On Custom Error Page
Sep 1, 2011I know it's possible in asp.net to create a custom error page in a web app, by putting the following line in the web.config: <customErrors mode="RemoteOnly" defaultRedirect="frmErrorPage.aspx" />
I have had to do this for my web app, since it is clearly much tidier than letting the program bomb out with it's ugly default error page. My custom error page just has the customer's logo and a brief message saying "Error has occurred. Please return to homepage"The trouble now is that I have no way of knowing what caused the error, when a customer reports it.
Is there a way to make the actual error message appear on this custom error page too?
