• .NET Development dynamically creating a form when receiving an event

  Hi. I have an instant messenger app. When a peer receives a message from another peer, his receive_message event is triggered and I'd like to spawn a new IM window. However, when I do so, it freezes. This class raises the event public class ClientProcess: MarshalByRefObject, IamShtoClient { //This event is used to notify us that we received a message. public delegate void message( object sender, messageWrapper mw); public event message messageReceived; //Raise an event when we receive a message [System.Runtime.Remoting.Messaging.OneWay] void IamShtoClient.receiveMessage(string message, string senderUsername) { if(_debug) log("received message: "+message+ " ...Show All

• Visual Studio 2008 (Pre-release) I think this is a bug in WPF DataBinding - bound ItemsControl ignores collection changes

  See details at the following post http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=765071&SiteID=1&mode=1 If I manually bind (via SetBinding) an ItemsControl to an (new, different) ObservableCollection, the ItemsControl (or some other entity) should monitor changes to that collection and update the ItemsControl accordingly. This does not appear to be the case. In the case that I simply bind once, in XAML, it works, but if the binding changes then the ItemsControl is never properly updated again. I can see that WPF does not explicitly register for the CollectionChanged event, so it must do something under the covers to track Collection Changes. Please advise. This works as expected for me ...Show All

• Visual C++ How do you install CRT, ATL80.dll, MFC80u.dll applocal?

  When we look at other installation options than side-by-side installations, we consider "applocal" installations. Unfortunately we cannot use side-by-side installation since it prevents “Per User” installations in Windows Installer. (See http://lab.msdn.microsoft.com/productfeedback/viewfeedback.aspx feedbackid=552c704c-75ba-4cb1-8bf3-0c1d6d50d5a2 ) A drawback with applocal installations is that fixes issued by Microsoft to components such as MFC80u.dll will not automatically applied. On WinXP I suppose MS can do this by using policies. I found a KB article where this is discussed: http://support.microsoft.com/default.aspx scid=kb;en-us;835322 As one of the points at the end of the KB article, you can read: " If you install ...Show All

• .NET Development Virtual Path Problem?

  Pretty much what I'm trying to accomplish is a data backup utility. First I have a treeview on the left, pretty much like Folder Explorer, that lists the drives and so forth. You then can dive down into different directories from there. The files and directories are then put into a listview on the right, after you select one of the nodes. This is where the problems start occuring. I'm including a piece of code here, just as an example to give you a visual understanding of what I'm about to ask. First make your basic windows form app. Add System.IO namespace Add a button Add listview control In your button1_Click event add the following DirectoryInfo tempDir = new DirectoryInfo ( "C:\\WINDOWS\\Downloaded Pr ...Show All

I know how to get the data and I know where, but I have no idea on how to get the spaces zero's and so on. Some help would be great! Thanks ...Show All

• .NET Development opening and reading text files

  I am new to visual c# and to programming in general. While I have taken a C++ class and have and understanding of if / else, while, for, do-while, etc., I have no clue when it comes to visual c#. Does anyone have a simple application that opens a text file (where the file name and location is entered on the form) and reads the file. Anything close would be appreciated. Ultimately I need to have an application that reads the text file, line by line, and compares it with a string that will also be entered on the form. Thanks!

• Visual Studio Team System Recording a Web Test on a VPC

  Hi. I need to record web tests on a VPC that resides om my physical computer, i.e. I have Team System installed on my pc and the web site that I need to record against is on the VPC running on my pc. If I start a new web test and TS opens the browser on my machine for recording, how can I point to the web browser to the VPC, or point to the VPC for that matter so that I can record and playback the script against the website on the VPC. At this point there is no TS running on the VPC itself... Are you unable to browse to the website on the VPC from the physical machine Why do you want the browser to open on the VPC. If this is what you really need then you will need to install VS on the VP ...Show All
