Why is UnhandledExceptionEventArgs.ExceptionObject an object and not an Exception?
...t that do not derive from System.Exception. This is not possible in C# or VB.Net but it is possible in other CLR based languages. Hence the API must support this possibility and uses the type object.
So while it shouldn't ever be null, it may not in fact be a System.Exception.
See CLI spec sec...
Any reason to write the “private” keyword in C#?
...o agree with this right before asking the question. But, some people write VB, some C++, some even F# (coming from other functional languages such as Haskell perhaps?), better than they do on C#. So, for them (and for us if we forget about it after 2 years of no c#ing) it's better if accessors are e...
Excel VBA - exit for loop
... @nixda Please remove your comment, as the hyperlink you shared points to VB.NET documentation, not Office VBA documentation. VBA's Exit statement has fewer options than VB.NET's. In fact, VBA only supports: Exit Do Exit For Exit Function Exit Property and Exit Sub. VBA has no Exit While. The corre...
What is the difference between “instantiated” and “initialized”?

What is the difference between int, Int16, Int32 and Int64?
...,3}, 1) = 0 (correct)
Array.IndexOf(new Int64[]{1,2,3}, 1) = 0 (correct)
VB.NET:
Array.IndexOf(new Int16(){1,2,3}, 1) = -1 (not correct)
Array.IndexOf(new Int32(){1,2,3}, 1) = 0 (correct)
Array.IndexOf(new Int64(){1,2,3}, 1) = -1 (not correct)
So my point is, for Array.IndexOf comparisons, only...
Difference between declaring variables before or in loop?
...
This is a gotcha in VB.NET. The Visual Basic result won't reinitialize the variable in this example:
For i as Integer = 1 to 100
Dim j as Integer
Console.WriteLine(j)
j = i
Next
' Output: 0 1 2 3 4...
This will print 0 the first ...
Is there a way to check if int is legal enum in C#?
...dd a new ALL value to your enum:
[Flags]
enum Language
{
CSharp = 1, VBNET = 2, VB6 = 4,
All = (CSharp | VBNET | VB6)
}
Then, check if the value is in ALL:
public bool HandleFlagsEnum(Language language)
{
if ((language & Language.All) == language)
{
return (true);

Bottom Line
You are trying to use something that is null (or Nothing in VB.NET). This means you either set it to null, or you never set it to anything at all.
Like anything else, null gets passed around. If it is null in method "A", it could be that method "B" passed a null to method "A".
