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.

Cannot Access Disposed Object.NET
Mar 26, 2009I have a windows form in .NET that will serve as a wizard to achieve something. This contains 3 steps: Step1, Step2, Step3.
Each step is again actually a user control. Main form contains a panel that display the current Step. When I change among steps then:
1) Dispose the current user control by calling its Dispose() method.
2) Clears the main form panel
3) Initialize the user control of next step and add it into the main panel
Now, the issue is, User control of step one contains one more user control. When I change to another step and come back to step 1, I get following error:
"Cannot access disposed object."
Because I have to first dispose the user control before actually displaying the another step. And when I come back to step 1 and tries to open the user control on step 1, it gives the aforementioned error.

CommandBuilder Custom SQL - Access The Items Through The DR Object?
Sep 25, 2009I have reached a situation where it probably makes more sense to pass custom Update and Insert commands to a CommandBuilder. I see that this can be done, but I have not found an example of how. The problem that I run into is this: The CommandBuilder iterates through the rows calling the Update or Insert command as needed. Writing the SQL for those would require accessing the items in the row. How does the CommandBuilder insert the row fields into the SQL? If I were doing it myself, I would be doing something like:
For Each DR as Datarow in Datatable
which would allow me to access the items through the DR object. What does the CommandBuilder expose for custom SQL to access the items in the row?

Forms - Error: Cannot Access Disposed Object
Mar 20, 2010I got the "infamous" 'Cannot Access Disposed Object.' error when I was attempting to open a form again after I had closed it. The fix (even though it's annoying), is easy enough; but again it's managed code problems and weirdness I still haven't changed my opinion that I won't be using MS .NET after this when I get my development box back to normal. BUT anyway the solution is self explanatory and very easy (and somewhat obvious) [Code]
the Application hiccups with a very nice message, after you close the form down and try to reopen it, that says: Cannot access Disposed object. So, my thought is that the "IsDisposed" property runs some sort of function to determine the Garbage Collection state and does a collection, or updates the request for the collection to be done.
