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 14 RepliesGetting Data Very Slowly And Sometimes Getting MemoryOutofRange Exception?
Dec 17, 2009I am working with serial port communications. I have very fast and continuous data on my serial port. I have a program to read data from serial port. I have comport.Datareceived event in my program to receive data. Now, the problem is there is data going every 100ms to comport. Will my comport.DataReceived event will receive also with that fast? Now,let's say there is data on comport and if I don't read it what happens to the data? The problem I'm facing is my dataReceived event is getting very slow after some time.If I stop sending data to my com, still my datareceiving program is receiving. That means it is not as fast as sending data.If I keep sending data from 4 to 5 days and coz my datareceived event is not that fast as sending, I am getting data very slowly and some times I am getting MemoryOutofRange Exception.

VS 2010 Data Bindings - Invalid Cast Exception With DBNulls
Sep 8, 2011I'm binding a ComboBox's SelectedIndex to a Nullable database field like so:
VB.NET
ColapsoComboBox.DataBindings.Add("SelectedIndex", EnsaiosBindingSource, "Colapso", False, DataSourceUpdateMode.OnValidation, 0)
As you can see, I've defined the NullValue to be zero, yet I get an InvalidCastException. Is there anything I'm doing wrong? Or is handling the binding's Format and Parse events the only way around this?

Exception Handling In Property For Ambiguously Typed Data Coming From Web Service?
May 7, 2009I need to consume data from a webservice. I am receiving xml data and using this to create objects through property setters.
In one particular case, an attribute of the object (called "is_active" and indicates whether the object is active or inactive in the application) is represented sometimes by
<field type="BooleanField" name="is_active">1</field>
and at other times by <field type="BooleanField" name="is_active">True</field>
The client code requires me to represent this using integers 1 and 0. The returned string "True" or "False" results in System.FormatException, as expected.
What is the most graceful way to deal with this situation?

View 3 RepliesError - 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
