.net-3.5

问题 Okay I'm having a brain fart here. This should be simple, but I'm missing something. I've got a win form and I'm trying to launch a web page when I click a button. The code for the button is here: private void button2_Click(object sender, EventArgs e) { try { System.Diagnostics.Process.Start("http://www.google.com"); } catch (Win32Exception ex) { Console.WriteLine(ex.Message); lblError.Text = ex.Message; } } When I run this on my computer, it works fine. On other computers, it only works if

问题 I have been trying to get the following scenario to work for around a week now with no luck. I have 2 applications, a .NET 4.5 application that is claims enabled, which is working perfectly well (works with other .NET 4 and up applications); and a legacy Intranet system built using WebForms .NET 3.5. The legacy application CANNOT be upgraded to a later version of .NET (would be so much easier). What I want to happen is that when I login on the .NET 4.5 application, I need to be authenticated

问题 I'm trying to use the BackgroundWorker class to start a new thread which loads a large number of objects into the cache when the website is started. My code so far: private void PreLoadCachedSearches() { var worker = new BackgroundWorker() { WorkerReportsProgress = false, WorkerSupportsCancellation = true }; worker.DoWork += new DoWorkEventHandler(DoWork); worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(WorkerCompleted); worker.RunWorkerAsync(); } private static void DoWork

问题 Error while running an installed Windows Service on dedicated Server I installed my windows service on my virtual dedicated server using the exe file of my windows service. When I try to run my windows service from a virtual dedicated server then I get following error. Service cannot be started. System.InvalidOperationException: Could not find default endpoint element that references contract 'MyService.MyServSoap' in the ServiceModel client configuration section. This might be because no

问题 So I recently updated my application to support a new feature. In the past if the configuration file was deleted by the user it wasn't a big deal. This new feature requires it to exist, and one of the requirements is that, the file exists in the application's installation directory. I have notice when the file is deleted ( depending on variables I have not figured out ) I get a .NET notification that the configuration file is missing or corrupt. Currently my program then crashes ( I still

问题 I have the following function + code to parse and query a webservice request then in theory store the results in the application (as it only needs to refresh once a day, which luckily is when the application refreshes). //tocommondata is a reference to the common stuff in the webservice var dCountries = toCommonData.PropertyCountries; //KeyValuePair var dRegions = toCommonData.Regions;//Array var dAreas = toCommonData.Areas;//Array var commonDAT = (from c in dCountries join r in dRegions on c

问题 I'm coding an app where I display a System.Drawing.Icon object on a System.Windows.Forms.Panel using a code that goes something like so: Graphics g = _panel.CreateGraphics(); g.DrawIcon(this.NodeIcon, _rectangle); I have code to move the icon around using drag-n-drop. My problem is that when the user move the icon around, it is anything but smooth. The icon looks distorted until the user stops moving the icon. I have tried to find information on this around the net but I can't get it to be

问题 I am using C# and developing a winform application. I have a project class which has the project attributes. the constructor of the project class is as follows: newProject = new Project(GCD_ID.IsNull() ? (int?)null : Convert.ToInt32(GCD_ID), txt_Proj_Desc.Text, txt_Prop_Name.Text, ST.ID.ToString().IsNull() ? null: ST.ID.ToString(), cmbCentre.Text, SEC.ID.ToString().IsNull() ? null : SEC.ID.ToString(), cmbZone.Text, FD.ID.ToString().IsNull() ? null : FD.ID.ToString(), DT.ID.ToString().IsNull()

问题 I have a simple form (MainForm) that opens another form (SubForm) which has a ToolStrip on it. There is nothing else on the called form. The calling form only has a button. The memory of the form that is called is never reclaimed because there is an eventhandler for SystemEvents.UserPreferenceChanged. I read that this is an issue that got fixed in .NET 3.5.1. [ EDIT The application runs on 3.5.1 so either it is not realy fixed or I do something different] Can I do something so that the GC can
