View 2 RepliesWindows - Access The My.Application Object From A Form Or Control Object?
Jul 6, 2011I have a solution with several Projects in it. There is a Windows App project (called ImportClient), and a Class Library (Import.Library). The Import.Library has functions to perform data imports (I have other applications in the solution that also need to call it). But the interactive application, I want to be able to pass in some form controls, and have it update the GUI. No problem. But, I also want to execute a DoEvents() so that the loop execution doesn't hang other interaction to the app.
So, ImportClient has a reference to Import.Library. But I can't add a reference to ImportClient to the Import.Library, because the compiler complains about circular reference, etc. I don't know how else to define the My.Application object of ImportClient as a parameter to the data function in ImportLibrary.
(I realize this is a dumb question - problem is, for this project I have a tight timeline, and haven't learned how to do the BackgroundWorker process. If you think I could pick it up quickly, I'm open to some hints about how to update the progress bar on the GUI, and how to pause / cancel the background task.)

View 6 RepliesObject Identifier To Access Object
Dec 22, 2009If I created a new instance of an object, is it possible to call that object's functions without knowing the name of that object that I initialized it to? Perhaps there is another way to access this object without using the name?Also, is it possible to create a property in a class which allows you to use that property to access an object of that class?For example, a textbox control has a (Name) property which allows you to use that name to access the textbox but that might be a special case because it is a textbox.

View 2 RepliesAvoid Linked Table Manager Message While Opening The Access DB?
Jun 27, 2012My Application ( Vb.Net) is to scan Access DB forms and find out the Activx control if present and it works fine. But my problem is.In some DBs we have tables with mapping path to specific locations (Table Property->Linked Table Manager) and when we relocate these DBs then we need to change the path manually otherwise it will show a message to re-link ( Access DB message) while opening the DB. And I am facing same problem while scanning through my Tool as well and my process stops, continue only by manual intervention.
Do I capture the massage event and send some user specific message to user in the Log file or Report and continue scanning further?

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:

Feb 5, 2012I'm using Visual Basic/Studio 2010 Express to run my VB program using MS Access database. I'm going to convert the Access database to a SQL Server Server Express data base so I downloaded SQL Server 2008 R2 Express onto my pc with Windows 7. The installation went fine and I actually converted my Access database to SQL server. I did not change anything in my VB program.My problem: When I run my normal program with the Access database (no changes), I now get an error when it executes the following code:
dr = cmd.ExecuteReader.
