I am trying to programmatically log error codes from any exceptions thrown on a PDA using CF3.5. Does anyone know how to get the most precise code for an error?
I've been looking at getting the HResult value of the thrown exception (which I can do), but this doesn't seem specific enough.
Here because even though I deleted the codes for logging in or make the condition wrong so that i will not log in.. still it logs-in to the system.
Dim username As String
Dim password As String
username = cmbUserName.Text

In C, Pascal, and C++ it is possible to use the FormatMessage function to retrieve a "friendly" error message that corresponds to a COM HRESULT error code. This question contains sample code that demonstrates the C++ approach. Of course it would be possible to build a managed C++ assembly to perform this function for C# and VB.NET code, but I'm wondering: is there a way to translate COM error codes using the .NET system libraries?

I created a class that I use for error logging. I have one method that accepts a parameter as an exception. With that exception, I created the error log and I write the message as well as the stack trace. With this, I'm finding that I'm not always getting detailed information. Usually, the stack trace shows me line number in which the error occurs, which allows me to pinpoint the issue.

Ok so I have alot of plans for programs coming up and I want them all to fade in and out so instead of copy and pasting from project to project etc I learnt about dll's
So when I added in the references etc and I typed in what I declared the Fadein function as which was "FadeIn" I got an error saying it needed to be declared
So I declared it as a string
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim FadeIn As String
FadeIn(Me)
End Sub
Then I get a different error saying Expression is not a method.
im migrating from vb6 to vb.net and have only very basic knowledge of .net. now i upgraded one of my projects, in which i had function cleartexts() which would clear all the text boxes of the forms. now to upgrade it to .net i converted it to sub (as it didnt return anything), so it looked like,
public sub cleartexts()
for i = 1 to 24
text(i).text=""
next
end sub
but .net 2005 gives the error, "expression is not a method", how do i call it then?? or what modifications do i need to make?

I have a problem with the VB.NET compiler failing to compile a class (in a separate C# assembly) which contains two overloads of a method with generic arguments. The equivalent code in C# compiles against the same assembly with no errors. Here are the two method signatures:
protected void SetValue<T>(T newValue, ref T oldValue)
protected void SetValue<T>(T? newValue, ref T? oldValue) where T : struct
Here is the code to three assemblies that demonstrate the problem. The first is the C# assembly with a Base class that implements the generic methods. The second is a C# class derived from Base and calls both overloads of SetValue correctly. The third is a VB class also derived from Base, but fails to compile with the following error message:
[Code]...
Am I doing something wrong in the VB code, or are C# & VB different when it comes to generic overload resolution? If I make the method arguments in Base non-generic then everything compiles correctly, but then I have to implement SetValue for every type that I wish to support.
Private Sub setView()
With lvwLogs
.AllowColumnReorder = True
.FullRowSelect = True

I am getting the same compile error for the forms with setview. I am thinking it concerns with listview. It highlights the public sub setview().
