I'm working on a base class right now, here's a basic rundown of it:[code]The problem is, in the Public Class bar example, some classes may implement MyInterface, and others don't. What I'd like to be able to do is have the sub New() in the structure in the base class "Foo" be able to tell if the class calling it (either the Base class, or the child class) implements MyInterface or not.

I am wondering how I would get the information on what errors get processed by the application.unhandledexception. I already handle the event and gather the information, but I am unsure how or what the best way to get that information to me (the developer).
So far I have vdialog that asks the user if he/she wants to send the error to me, kind of like when an error occurs in Windows XP and a dialog asks the user if they would like to send information about the error to microsoft. I am unsure what to do when the user clicks "Send".
I have thought about emailing to me, but I don't really want to put my email address as the from, because I might change it or its password in the future, thus breaking its usability.
I cannot yet do an anonymous FTP upload, because my website only allows one FTP user, and that is used only to update the website.
I also have thought about using the user's default email program, but that will not work in most cases of people who rely on web mail.

I have created a class called clsTest, this contains the sub "logInfo", when this is called within another class (e.g. "clsOther") some information about the other class is logged to a file.
I want clsTest to be able to get some general information about clsOther, specifically it's type and/or the sub/function that called the "logInfo" sub in clsTest. I could pass these as additional arguments in the "logInfo" subroutine but I was wondering if it was possible for clsTest to know what had invoked it (or any other class for that matter).
I'm getting 'Catch' cannot catch type 'Object' because it is not 'System.Exception' or a class that inherits from 'System.Exception'. and 'Expression detected' Code underlined in blue: Catch obj1 As Object When (?)

I've got a bunch of DLL projects that I'm pulling into my application, each contains their own Settings.settings/app.config. When I compile the app and run for debugging, everything works just fine, but come deployment time I can't get my DLLs to read their own settings files.I've been doing some reading and it has become apparent that there's a couple of methods to getting each dll to read its own configuration - one is to dedicate a .dll.config to the library and the other is to embed the dll's configuration in the process.exe.config.I'm having significant issues trying to implement either and I wondered if anyone has any good docs on this - there appears to be a shortage on the Net.
I'd like a separate .dll.config for each of the libraries if possible, but in a pinch, getting each of my libraries to read their own section of the process.exe.config will he right direction because I'm so close to rolling this application out but this stumbling block is causing me a significant headache.Edit: When I merge the configuration files, I start getting TypeInitializer exceptions when I initialize objects withing my libraries. This is likely just me being retarded, but does someone have a working example of a merged config file and some basic demonstrative code for reading it from multiple assemblies?
Two of us at our company worked on a VB project. I developed the GUI interface. Another programmer developed some of the Classes that are also part of the project/Solution. Our manager wants to see as part of the 'Help/About' drop down, the version of the GUI application as well as the Class that the other programmer wrote. We are on the third modification of my GUI application, but the 8th version of the class that the other programmer wrote. Is there some way that the GUI application can get the 'Assembly Version' information for a class that may not necessarily exeuting at any given time?
View 3 RepliesI have a class that pulls the ID3 information from an MP3 file. This information is at the very end of the file in plain ASCII. The original author is using FileGet to retrieve just the last 127 characters of each mp3 file. The issue is that this information is put into strings declared like this...
Public strTag As New String(" ", 3)
Public strTitle As New String(" ", 30)
Public strArtist As New String(" ", 30)
[CODE]...
This part all works fine. But I'm trying to code a property that returns a string like this...
return strTitle & " - " & strArtist
But for some odd reason it is being very strict about the length of the returned string. It usually just returns the strTitle, and not the " - " or strArtist, and if I switch the positions, it will just return strArtist. So obviously both Strings have information in them.
I'm an intermediate programmer, but just breaking into VB.NET. I'm not sure what the New String(" ",30) part does, but it is definitely interfering with the string concatenation that I'm trying to return. Anyone ever had a similar issue?
I've tried String.Copy, String.Concat, etc. I've also tried doing ReadtoEnd(), but it takes forever for just 10 mp3 files, so I can't imagine how long it would take with a whole library. The only thing that slightly works is if I do... return strTitle.SubString(0,5) & " - " & strArtist.SubString(0,5)
But like I said, coincidentally it will only return around 30 characters.
I have a collection of objects (classes I created), and each one ties to a record in a database. I want an easy way to update the information, so I thought about declaring a record in the class, that would tie to the record on the database. However, I'm having a problem updating it now.
1) Can I declare a global variable for the data context, and leave it open the entire time the program is running? This would solve my problem, but I don't know if I can do that.
2) If not, besides coming up with a complicated class to do this, is there an easier way? Here is an example of what I am trying to do:
VB.NET
Public C as Record
Public Sub GetValue()
Dim SQL As New DBDataContext
Dim X = From T in SQL.Records Select T

I am in the process of prototyping a small sockets application, which monitors IT infrastructure (due to in-house financial and deployment restrictions, I am unable to utilise an existing commercial or open-source solution). Basically, I have a server application and associated agent process for communicating heart-beat data to the server. The server application implements a TCP socket class (TCPDevice), which is called from a WinForm. I am aware of the restriction on updating the UI from processes running on separate threads, and that the preferred technique for acheiving this is via the use of Delegates in conjunction with the Invoke method. Having had very little need previously for using Delegates (apart from of course std windows events and the BackGroundWorker control), I am at a loss as to how to do this in the context of my application, and would appreciate some assistance, although it has occurred to me that I could use the backgroundworker for marshalling updates to the UI.
Eventually the application will need to update a grid of devices via feeds from the defined agents, however for the purpose of this exercise simply updating a status bar on the UI will suffice. The section of the code which I believe is relevant to propogating the code to the form is contained in the OnDataReceived method.Below is a code excerpt from the protoype app which should put the above into appropriate context:
Code from the form:

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:

View 3 RepliesI'm relatively new to VB.NET and am having a problem when Databinding a Class to a Forms Controls. Basically within the Class, when Setting certain String Properties I heck that they are not Null/Empty and if they are Throw an Exception. The problem occurs when I bind the properties to textboxes - when the textbox is empty I expect an error to occur (which I will handle). So does anyone have any insight or solutions into why the exceptions are not being thrown when a textbox changed to an empty string?
