Catch An Exception And Throw A New Exception Which Wraps The First Exception As An Inner Exception
May 8, 2009It is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:
View 1 RepliesDatabase - Exception Occurs When Trying To View DataGridView
Nov 7, 2011I have a very simple table in access. The data is stored from VB.NET using the OLEDB adapter. I have a second form which has just a single DataGridView which was dragged/dropped using VS2010 from the Data Sources window.When trying to view the window the first time no data is shown and the second time an exception occurs and the program closes.
[code]...
In the Immediate window after clicking the Form.ShowDialog() button this message appears: A first chance exception of type 'System.ArgumentException' occurred in System.Data.dll Also, the data does not load into the datagridview. After closing the window and then clicking the same button (Not data has been changed at all) this error appears: Input string was not in a correct format.Couldn't store <07/11/2011 00:55:06> in Time Column. Expected type is Int32.

Null Dates In Mysql Throw Exception When Loaded Into Datagridview?
Feb 15, 2012Having problems with null dates in a mysql table. Have eventually found out that I can store a 'null' date in mysql as "0000-00-00" and I can run the 'insert' command to add a record to the mysql table. When I check on mysql workbench I can see the row has been inserted correctly and the date shows as "0000-00-00".However...When I try to load the table into a datagridview, I get an error = mysql Conversion Exception was unhandled = "Unable to convert MySQL date/time value to System.DateTime".
View 4 RepliesForms :: DataGridView DataError Exception When Removing Items From Bound List?
Nov 2, 2011I am using a DataGridView bound to a BindingSource which is itself bound to a List of objects. This all works well until I remove objects from the list. If I am scrolled down to the bottom of the DataGridView and then remove a bunch of items from the list it is bound to it generates a DataError exception because the length changed and the rows I am looking at no longer exist... I changed my code to handle that error, but now instead of popping up a message it SLOWLY erases the data in each of the newly invalid rows at the end of the table (I think each time it does one it generates a new DataError, which is why it is so slow).
How do I prevent this? I want to be able to dynamically (and programmatically) add and remove items from the table without the possibility of this error... I assumed this would be handled automatically as part of the data binding process but I guess not.

Error - A First Chance Exception Of Type 'System.Exception' Occurred In Microsoft.VisualBasic.dll
Sep 2, 2009I have a large project where we have 2-3 dll projects that are converted from VB6 to VB.NET. We have fixed all the issues that caused compilation errors, and most of obvious issues in running, so now we have basically a program up and running. The exe is created from scratch in VB.NET, using a lot of functionality from the converted dll's (including GUI forms). What I wonder is when I run the program in debug mode, I get a bunch of warnings in the "Immediate Window" saying:
A first chance exception of type 'System.Exception' occurred in Microsoft.VisualBasic.dll
...and some of other type (but most of them in Microsoft.VisualBasic.dll).I was wondering if this is common in projects converted from VB6, or if it is caused by bad design in our code...

Jan 11, 2010When catching an exception in .net, you can have as many type-specific exception blocks as needed. But I usually try to have at least one "general" exception catch block. But is there a way to get the type of the "real" exception thrown that is caught by the generic exception handler, perhaps using reflection?For example, if I have

Generic GDI+ Exception Followed By OutOfMemory Exception?
Sep 1, 2011I'm working on a VB.Net WinForms app. This app shows rows of production lines that the user will go down row by row and print a package of ActiveReports documents. This package can contain up to 9 reports. The package is selected and told to print, it then gets sent directly to the default printer of the machine using ActiveReports' mechanism:
rpt.Document.Print(False, False, True)
These reports also use images pulled in from the file system. When they run through the rows quickly, they sometimes encounter:
A generic error ocurred in GDI+
Then followed by:
Exception of type "System.OutOfMemoryException" was thrown.
This causes some documents to not print and they have to go back and figure out which ones didn't print. I know the machine is not out of memory, so my assumption is that the printer memory is filling up or reports are trying to use the same image when printing and causing an issue there.If it is the printer memory filling up, is there any way to slow down the adding of documents to the print queue, or at least pausing to wait for space?
