• Visual C# generic methods

  I want to be able to implement a strongly typed IClonable, so that I can clone based on lineage. public interface IClonableObject { T Clone<T>(CloningFlags flags); // flags specify level of cloning } so that I have something that looks like: public class Foo : IClonableObject, IFoo, IBar { string bar = ""; public string Bar { get { return bar; } set { bar = value; } } T Clone<T>(CloningFlags flags) { switch(flags) { .... case CloningFlags.ShallowCopy: { return (T)MemberwiseClone(); } } } } and can use it like: Foo f = new Foo(); Foo b = f.Clone<IFoo>(CloningFlags.ShallowCopy); I know this syntax (and most likely logic) is wrong.

• .NET Development Executing a query against Access and Excel

  Hi, there I wrote a program that reads data from both Excel and Access. But I don't know how to submit a query to both of them. Connection to Excel is made through OleDb in code, and Access connection is made through Database Explorer, in design time. The question is: how can I make reference to these sources Thanks, Flavia Hi, You can execute queries on these datasources by using a Command object. Since these 2 sources are using OleDb then you would use the OleDbCommand object. Just use your connection on your datasources for your command to be directed to its proper datasource. Ex: OleDbCommand myComm = new OleDbCommand("SELECT * FROM AccessTable", connAccess); You can then use the execute method if your ...Show All

• Community Chat Is MS trying to throw away menu bar?

  In IE7, classic menu bar is disabled by default. In Office 2007, there is not menu bar at all. Also the traditional toolbar is gone. I can't find a way to create my own custom toolbar too. What's happening I know menu bar is very classic and not pretty, but it is one single place that I am 100% sure that I can get all the features from a program. I don't want to lose it.

  Is it possible to install VS Team Dev and then VS Team Arch over top to get the features of both Will doing so screw up any other apps e.g. Visio for Arch, or disable ability to profile (from Team Dev) cmk Yes you can: just install multiple versions on top of each other and then the service pack. It has been working fine for me and my team. Note: Installing all the different 'flavours' does not make a "Team Suite" edition... Team Suite includes extra "stuff" that is simply not available in the Tester, Architect and Developer editions.  ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Memory leaks disposing AudioVideoPlayback.Video object

  Hello. Sorry if this question is not in the right thread. I'm writing C# application for continuous video playback using the Video class from AudioVideoPlayback namespace. I create new Video object for each movie clip disposing previous one and I face the memory leak problem if I set Audio.Volume property somewhere; the Audio object is not disposed. This leads to E_OUTOFMEMORY exception when trying to play 10th or 20th clip. Now I've commented lines that change Audio.Volume and application operates normally. Is there any way out of the situation I don't like the idea to change the master volume... Thanks in advance, Victor. ...Show All

• Visual Basic Forms.keypreview ????? not exist?

  Hi experts, currently I am trying to use keypreview to disable the auto-submit from clicking "enter" when focusing a textbox. So I am going to turn keypreview to false. However, I can't find it!!! it's not in Forms....anybody can tell me how to do it I am using Visual Studio 2005 and 2.0 .net framework. Thank you very much yours, armansiu As your trying to create a web form - you'll be using ASP.NET and I would probably suggest the forums at ASP.NET as a better location to get an answer to you question. Forms.KeyPreview is a windows form concept and is probably not applicable to web forms, and therefore there may be a better way to achieve the results that you want. forums.asp ...Show All

  Hi I have been learning on how to use the new features of the .NET 2.0, and Well I using VS2005 and everything is pretty straight foward.

• Visual C# Exposing properties

  Hi! My idea is to include into language a mechanism to expose a field's properties. Let's say I'm inside some WinForms user controll. My control's got a label named label1. I want to expose the Text proprety of the label inside my user controll class and call it LabelText. The main pattern idea is to 'inherit' all the child's property attributes automaticly (like DefaultValue, Browsable and so on - these are just examples, Text proprety's got some others). I would only have to write single line of code that would do everything for me, like public LabelText = label1.Text; One problem I've noticed is that some of the attributes may be of private nested inside that class types, like class MyClass { [AttributeUsage(Attribut ...Show All

• .NET Development Detecting Disconnected Sockets

  I'm creating a multi-threaded Tcp-Server, each thread reads from it's Network Stream in blocking mode. How can I detect if a client is lost (not disconnected correctly) My server works by catching the IO exception or receiving 0 bytes from the read function to alert a disconnect. The problem is closing the connection (and thread for that matter) when the client's power is lost or it loses network connectivity. Any help would be appreciated. Thank you. Yes, I handle those 2 situations correctly and the connections are properly closed. However, if the client's ethernet cable is unplugged or it's power is turned off, I do not recieve ANY exception in the server and the port stays open. ...Show All

• Visual Studio Express Editions designing individual panels?

  Hello everyone! this is my first post here. Im just moving into C# and .NET after a few years working with C++ and various GUI Libraries/frameworks. (MFC, wxWidgets, WTL, etc.) Is there a way to use the IDE’s form designer to design individual panels not whole forms, but panels. in other words, to create a panel class that is not "attached" to any form. The idea is that my favorite approach to designing complex GUIs in my applications is to have a main screen, where diferent "views" are shown one at a time, think of it like a tab control, but without visible tabs, the user "invokes" these views by choosing buttons on the toolbar, main menu, dialogs, etc and i programatically show/hide or create/dispose the ap ...Show All
