PropertyInfo.SetValue Argument Exception

Aug 23, 2005

An argument exception is thrown when attempting to use PropertyInfo.SetValue to set the value of a property in my business objects.The argument is thrown because of wrong data type, even though a valid cast could be made.Is there a way to dynamically cast the object type into the underlying PropertyType of the PropertyInfo object without having to test the FullName property explicitly as show below?

Select Case prop.PropertyType.FullName
Case "System.String"
prop.SetValue(obj, tbx.Text, Nothing)

.net - Exception With String Argument?

Jul 28, 2011

I have :

Dim con As New OleDbConnection(My.Resources.ConnectionString)
// Give exception = Format of the initialization string does not conform to specification starting at index 62.

When I substitute the actual value of the Resource, it give no exception :

Dim con As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:
awData.xlsx;Extended Properties=""Excel 12.0 XML;""")

The value of ConnectionString in Resources :

<data name="ConnectionString" xml:space="preserve">
<value>Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:
awData.xlsx;Extended Properties=""Excel 12.0 XML;""</value>
</data>

I don't understand why is this happening ?

I think this should have been replaced even before the compilation process..

Then why is it giving exception ?

VS 2010 Error Message : Argument Out Of Range Exception Unhandled

Jun 23, 2011

Working with an If statement I have tried the following

If -0.6 > (LLum_Gline(8).X - LLum_Gline(12).X) > 0.6 Then
patient_frm.llum_gline = 2
MsgBox("Measurement is Abnormal")

I am getting an error message that says Argument out of range exception unhandled. I have double checked and verified that LLum_Gline(8).X and LLum_Gline(12).X are in fact valid.Is my problem simply in how i am phrasing the If statement. Is there a way for me to phrase what im doing without writing multiple if statements?

Caching Propertyinfo Of Abstract Class?

Jan 19, 2012

I've been playing around with implementing an abstract base class that using reflection accomplishes SQL to Object mapping.

I did some benchmarks and decided I wanted to implement a caching strategy for the property info of the objects (to prevent future lookups on them). My first instinct was to try and implement something like this.

Public MustInherit Class BaseModel
Implements IFillable
Private Shared PropertyCache As List(Of PropertyInfo)

.net - SetValue/GetValue Versus Directly Accessing Array Via Arguments?

Jun 4, 2012

I have an array which originally was a Variant array in VB6. Example code in VB6:

ListBoxDrawings.List(X1, Y1) = myArray(X2, Y2)
myArray(A, B) = ListBoxDrawings.List(I, C)

After running it through ArtinSoft's VBUC, its values are handled using GetValue & SetValue.Example code in VB.NET: (ignore conversion to ListView)

ListViewDrawings.Items(X1).SubItems(Y1).Text = CStr(myArray.GetValue(X2, Y2))
myArray.SetValue(ListViewDrawings.Items(I).SubItems(C).Text, A, B)

Since VB.NET doesn't do Variants, I figured out that the array should be typed as a 2D String Array. It seems like there's no reason to use GetValue/SetValue, as the former returns an Object and the latter takes one. This means that I'd have to cast the returned object as a String (Cstr) if I wanted to assign it to a variable, which seems like a pointless extra step that might introduce errors. Also, since the method has lots of overloads, the code might not be as clear. Is there any advantage to using SetValue / GetValue, or should I just consider that an artifact of VBUC converting a Variant, and access the array directly like the original code did?

VB.NET without Get/Set methods:

ListViewDrawings.Items(X1).SubItems(Y1).Text = myArray(X2, Y2)
myArray(A, B) = ListViewDrawings.Items(I).SubItems(C).Text

Catch An Exception And Throw A New Exception Which Wraps The First Exception As An Inner Exception

May 8, 2009

It 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:

Error - A First Chance Exception Of Type 'System.Exception' Occurred In Microsoft.VisualBasic.dll

Sep 2, 2009

I 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...

When Catching A General Exception, How To Determine The Original Exception Type

Jan 11, 2010

When 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

Catch ex As System.ServiceModel.FaultException(Of InvalidUser)
ProcessModuleLoadException(Me, ex)
Catch ex As System.ServiceModel.FaultException(Of SQLExceptions)

Error 68 'Catch' Cannot Catch Type 'Microsoft.Office.Interop.Outlook.Exception' Because It Is Not 'System.Exception'

.net - Re-throwing An Exception From An Exception Catch?

Feb 14, 2011

catch an exception and then throw another exception? Like so:

Try

Catch ex As Exception
' Operation xxx failed, need to execute cleanup

[code]....

The reason for doing this is that while I catch my exception on a higher level logic (to make sure I can log it properly), I need to do some actions in the event of the exception that I can only do inside my class/function.
