Is it possible to add properties to a class temporarily at run time? I'm saving the locations of some user controls with serialization. The user controls can't be serialized, because controls can't, so I need to store the locations in some related objects which I can serialize. I need the related objects in any case. The related objects only need this data for serialization, and it would be nice if I could just give them the property for storing this information while serialization takes place. Is there any way this can be done?

Hi, I have a multithreaded server app (Winforms) that I have converted to a service. It has a thread that simply creates a new TcpListener and waits for a connection: Public Sub StartListeningThread() Do Dim ip As IPAddress = IPAddress.Any Server = New TcpListener(ip, 4000) Server.Start() Dim tcpTmp As TcpClient = Server.AcceptTcpClient Dim tcpClient As New RUHTcpClient tcpClient.Client = tcpTmp.Client Server.Stop() Connections.Add(tcpClient) Loop End Sub This thread runs for the life of the application. The problem is that without using the command…

I'm trying to get an instance of a Delete button on my webform in order to display a warning msg to the user. I've done this type of thing several times for a button inside a datagrid for a user confirm to delete a particular record. this webform has no datagrid. Simply a delete button. However, the form is set up as having multiple placeholder controls depending upon which functionality is initially selected. The following is the html within my webform: <asp:Button id="btnDelete" Text="Delete" runat="server" class="eppbutton"/> The following info is in my code-behind: ElseIf Request.QueryString.Item("iManage") = 3 Then 'Delete plcAddF…

Hey All, Need to know if there is a way to enlarge the scroll bar and drop button on a combo box. I know the drop button gets bigger if you increase the font size but is there a way I can do it without making the font to large. This is for a touch screen application so buttons must be a fair size. Thanks in advance to anyone that helps.

I have this problem when I am writing and reading network streams. If I send another packet, then it will also send the last packet again, so I end up sending more and more information. Somehow I mustn't be flushing the buffer out correctly or something. This is my output if I click a button 3 times - you can see by the third time it has sent the packet 3 times, and hence the server replies 3 times. To send a packet I am using: Dim ns As NetworkStream = Client.GetStream If ns.CanWrite Then Dim bytes() As Byte = Nothing bytes = System.Text.Encoding.UTF8.GetBytes(Msg) ns.Write(bytes, 0, bytes.Length) End If …

I'm attempting to get the site to have valid HTML - this is causing much grief due to several reasons (most of which arent .net related so i wont ask about them here) The one that *is* related is that the built in .net controls, eg an image button is writing out html with attributes which are not accepted by the HTML validator (http://validator.w3.org). My code reads: <asp:imagebutton id="btnLogin" onclick="doLogin" tabIndex="3" Runat="server" imageurl="enterButton.gif" width="45" height="18" EnableViewState="False"></asp:imagebutton> The outputted HTML is: <input type="image" name="btnLogin" id="btnLogin" tabindex="3" src="enterButton.gif" b…

Couple of (hopefully) quick questions here. 1)I've been using Process.Start(filename) to open programs and files fine for a while now however if its a filetype with no known extension is there anyway to open the windows openwith dialoge? or do i have to code my one in which case how do i access the list normally provided by windows in said dialoge. 2)If i was to write a text editor, (C#) how would i access the data from a file opened with my text editor. 3) How would i (through code/ in the setup program) tell windows to use my application for certain file extensions? C# for answers is appreciated but any answer is great thanks in advance.
