is it possible to link a personal created class with a Mouse Event? I created a class and I want to make it possible to make it interactive with the mouse. So when the user goes over the GDI-created shape (which is declared and created in that class), he has to see some information about that shape, like the name etc.... And the user has to be able to drag and drop that shape.

I am converting an old Vb6 solution to .net 2.0 in vs2010. I've been working in C# for about 3 years now and .net for 5. I don't recall having this problem in C#, but if I want initialize a readonly collection of DerivedControlFoo Is there a clean way to do it besides creating a sub to do it all off somewhere else? I'd love to be able to do it at the class level at the declaration for readability and simplicity.

I am trying to figure out a way to include the listview's tag field when dragging one listview's subitems into another listview. I am hoping someone here has experience with this. My Listview drag code is below - the two listviews that I am dragging subitems into or from are LV1 and LV3. Also, this is being done in Visual Basic 2008 and the project is a windows application.

Example:
Two files - TestClass.vb, myForm.vb
TestClass.vb looks as follows:
Imports System.Threading
Public Class TestClass
Private myClassThread As New Thread(AddressOf StartMyClassThread)
[code]....
The result:Application runs, no errors or exceptions.Displayed is the listbox and the Start button.I press the start button and a msgbox says "Not Invoked" as expected and upon clicking OK to that msgbox "Start Button Pressed" is added to the Output listbox control.Immediately following that the msgbox pops up again and says "Not Invoked". I was expecting "Invoked" as a separate thread is trying to use the Output listbox control.Of course this results in the Output.Items.Add being attempted which results in no visible result as the thread is not allowed to directly update the UI control.

For Each DGR As DataGridViewRow In dgvJobs.SelectedRows
' Added to stop error occuring when destination dgv columns do not exist
If dgvProject.ColumnCount = 0 Then
For Each ColumnHeader As DataGridViewColumn In dgvJobs.Columns
Dim name As String = ColumnHeader.Name
[Code] .....
I'm making a form where I have two datagridviews. The first dgv is databound to a database. The second dgv is not databound. I want to allow users to drag rows from dgv1 and drop them on dgv2. At the moment I have managed to get it to the point where I can drag from dgv1 to dgv2 but the result is an empty row being added. When I try adding a row without using .Clone I get this error "Row provided already belongs to a DataGridView control."

This is a little diffrent from your standard drag and drop, but I am trying to find out a way to support drag and drop, from a list control, which is displaying a list of files, held as "blobs" in a SQL database (compressed data in my own format). When the form is opened, I obtain a list of all the file names within that given table in the database, and display it to the user in the list view control. The user then has the option of dragging that ListItem from the ListView on to the dektop (or other directory location). Upon doing so, I need to be able to read the data from SQL, decompress the data (in my own format) and then save it as a file at the dropped location.
My main problem is detecting when the ListItem is dropped outside of my application, as I want to use this dropping event to trigger the code in to obtaining a copy of that file from the database, and save it in to the "dropped" directory, where ever that may be.
So Im mainly looking in to how I can "see" the final location where the item is dropped, and how I can start off the drag and drop operation in the first place with no initial data (since I have not obtained the file at the start of the operation). Getting the file at the start of the drag and drop operation intoduces "lag" while the application makes the trip to the SQL database (via web service) and obtains the data, so I need to carry out that trip to the database, at the end, while still allowing "Windows" to act as if I am dragging and dropping a file...
I did consider multi-theading, and downloaind the file from the database while the drag and drop operation is in progress, but then it becomes a race between the data being obtained from the database, and the user dropping the file.
Im using VS2005, SQL 2005 where the file is stored as a blog. SQL is on another PC running a web service which I interact with, to allow my application to talk to the database over both a LAN and WiFi via the internet. Compression and de-compression is handed at the client side application (for the file itself, in order to reduce the footprint created by the internet traffic) , where the user interface is displayed.

I have created a class and want to distribute it without giving off my code/create it as an application. I am aware that components are nearly no longer used and their disadvantages. I dont need to draw anything on the ui. (I know basically components are used for this aim but I just need to try this :] )
My question is: My class uses a webbrowser because webclient and web request don't work for me. When I start vs 2010 and select new project - Class Library and include the namespace System.Windows.Forms it doesnt find it. So first of all should I select class library to create a component and how could I include the webbrowser object?

I have a 'property management class' that contains several functions and properties. I have several other classes that use the 'management class' as a property to derive the value of several of its other properties.Is there a way for me to reference the outer class from the 'management class' functions without having to pass it as a parameter? I ask because several different classes can have this 'management class' as a property and am having a hard time typing the parameter.

I am looking for a serial port component for .NET that overcomes the issues with the built-in Serial Port component related to sudden unplugging of USB-to-RS232 adapters, and suspension of the computer while the port is open. (Untrappable errors occurring after the the device is unplugged or the computer comes back after being suspended.)I have been using Richard Grier's solution, but I still have problems when resuming from suspend.Is there a 3rd party component that you would recommend? I have tried several, and each have their shortcomings. Ideally I'd like a drop-in replacement for the standard serial port, but I'll take whatever I can get.
Edit: It turns out that upgrading to .NET 4 and using the serial class works fine on XP, but does not work on Windows 7.
