• Visual C# serialize mail messages

  For a message queue I need to serialize (and later on deserialize) many MailMessage s. Quite generally I ask myself, which is the best way to do this To .eml To a mbox format How can this achieved Are there any free libraries (open source preferred) Thanks a lot Jan Yeah, it can get heavy on disk access if you have alot of mail going through that box.  I did do load testing and I averaged it out to be about a 25% performance loss for 1000 messages with the sink activated.  Although my event sink is really heavy, it is multi-threaded so I gain some performance back there. You don't need to be running Exchange or an event si ...Show All

• .NET Development .NET Remoting & Indigo

  I had a look at the famous article "Introducing Indigo: An Early Look" ( http://msdn.microsoft.com/library/default.asp url=/library/en-us/dnlong/html/introindigov1-0.asp ) and I would like to add another row to the comparison table and that is "activation model", while .NET remoting has got a comprehensive model for activation (Single call, SAO, CAO), web services on the other hand just support single call. My question is about Indigo, Which model does it support I used the CAO model and it was wonderfull, its model is very close to local object oriented model and basically you can have one piece of code for both of local objects and remote ...Show All

• Windows Forms How to bind to BindingSource.Current?

  Hi there, I currently wonder how to use the BindingSource class in a seemfull manner. I have written a UserControl that has a property where you can set a BindingSource instance as a source of addresses. I also have a BindingSource on my Form. The control should display and allow editing of the current address. The "current" address is the one that is the value of the Current property of the "external" BindingSource, the one on the form. When I assign a BindingSource instance to the control that encapsulates an address table, the internal BindingSource of the control does not have the same value for the Position pro ...Show All

• Windows Forms Sharing classes between projects in a solution in Visual Studio Express Edition

  How do I share classes between projects in a solution As I read misc. help topics, this should be possible, but it seems like menu items for it is missing. Could this feature be disabled in the Express Edition of Visual Studio C# Here's one way: Choose "Add existing item" and browse for the class file. Do not click "Open" button (in a FileDialog) but instead click an arrow just beside the "Open" button. Select "Link" option and you will have selected file added to VS solution as a "linked" file (with small arrow indicating a link on the file icon). When y ...Show All

• Windows Forms Modifying Images

  I am trying to create a program that displays a map, which is a satellite photograph, of  a street or community for example. I want to design it so that I can have several small icons on the form that users can drag and drop on the map, to "mark" certain spots on the map. I then want the user to be able to save these changes to the map, and print the map with the icon on it. Can anyone point me in the right direction, maybe an idea of what objects or namespace is capable of this, or a tutorial Thanks in advance, smtraber Chris, you're awesome! I'm gonna have a go at it and hopefully I'll get it working. Thanks again, smtraber ...Show All

• Software Development for Windows Vista How to provide paths to Runtime for CreateWorkflow from XOML?

  My XOML contains custom activities. How do I provide the paths to the custom activities assembly so it can resolve them I know one way is to put all the assemblies together with the host. But sometimes the assembly are located with the "client" app, not the "runtime host". With WorkflowCompiler class you have librarypaths property, however the runtime compiles directly from XOML, and I can't see librarypaths for the runtime. In http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=208634&SiteID=1 Vihang seems to use TypeProvider as a runtime service. But that still doesn't solve the problem of paths. you can wri ...Show All

• SQL Server Default Web Site using wrong IP

  I just installed sql server 2005 on a windows 2003 server.  I chose the option to install but do not configure.  After restarting, I used the Reporting SErvices Configuration Manager and it all looks ok.  When I browse to //localhost/reports I get a rs page with the message of: The request failed with HTTP status 400: Bad Request. One slightly unusual thing is SQL Server 2005 was installed as a named instance ("(local)\SQL2K5") - the server's default instance is a sql 2000 installation, which had RS installed and running.  Before configuring RS for 2k5, I deleted the VDs for Reports and ReportServer ...Show All
