• Visual Studio Team System Source Control Settings

  When and why one should use the check-in, check-out policies in Source Control Settings Please explain by example Thanks Are you talking about the options for "Select lock type" when you do a "Check-out for Edit" When you check out a file for edit in TFS, you are actually telling the server that you are going to edit a particular version of a particular file that you have in your local workspace. At that point, you can optionally select one of three lock types:- "none", "check-out" or "check-in" Lock "None" . T ...Show All

• Visual Studio 2008 (Pre-release) DataContext lost in a ModelVisual3D??? Is it a bug?

  Hi all. At the end of this post I added 2 pieces of code. Basically, the second one is the same as the first one but wrapping the _itemContent with a Viewport3D so that 3D animations are possible on the list items. In both cases the _itemsContainer.ItemsSource is set in the code behind in the Loaded event handler of the Window. However, the 2nd code doesnt work and after many experiments I detected that the DataContext is lost. My question is: is this supposed to happen For some reason the VisualBrush "blocks" the cascading of the DataContext Is there another way to create a 3D ItemTemplate The Templating2 sample here http://msdn ...Show All

• .NET Development registering for COM interop creating duplicate registry entries.

• Windows Forms Should be simple: frm1 Save As... frm2, but leave frm1 "as is"

  I tried to save Form1 as Form2, leaving Form1 "as is" (it's OK whether IDE leaves Form1 in Project or not). Seems VS.NET merely renames Form1 to be Form2--not what I'm trying to get. (I want to experiment with the UI on Form2, but have Form1 in the directory just in case I prefer the original). in Solution Explorer, click a ...Show All

• .NET Development Method Authentication for Internet public Web Service

  I need to create a web service to be consumed in the public internet. I woul like to use a declarative mode. From the WSE 3.0 documentation I have two posibilities: UserName or Certificate. I can not use certificates in the actual project, so I have only the UserName option. Is this correct But I need the X.509 certificate in the server, and copy the public part to the clients. Is this correct Thanks a lot for your attention! But the role or user authoritation requires also the certificate, at least using the WSE setting tool. Have you checked it ...Show All

• Visual Studio Express Editions you must have a license to use this activex control

  I'm very new to C# so this is probably a simple thing. I am working on a project that uses an activex control and some other third party dlls. Whenever I click on the main form window I get an error telling me I must have a license to use this activex control. Of course, I do have the license but it isn't doing it's trick. Some background.... The sample source I'm working on was created in an earlier version of visual studio. The sample was "upgraded" when I loaded it. The sample does compile and run just fine but I can't edit the main form because of the error. I'm using visual studio 2005 express for C#. ...Show All

• Architecture Advantages of OOP ?

  Hello, Im a fun of OOP designs. I design my bussiness classes when I start a new project. Then maybe I will write mapper classes for bussiness classes to map DB tables or using an O/RM tool or an ODBMS . Think that this project is big one and it has long deadline. You will develop it 2 or 3 years. Requirements will be changed. To develop this project with OOP designs and n-Tier application design is good idea. But I am asking myself this question "Why am I choosing this long way ". I think the advantages of OOP are re-usable and flexible (when there is a new requirement). OOP makes less code behind user-interface. But I dont un ...Show All

• SQL Server Incremental Extraction

  Does anyone know whether you can dynamically configure the SQL used for the source (in an OLE DB Source) in a data flow.  I used to used some ActiveX in DTS so that I could set a different value in the Where condition of the SQL statement for each datapump.  Using this code, I could use a different date for each datapump source based on data I have stored in my destination database. I know that I could use SSIS variables but this would mean that I would have one variable per "datapump".  I would prefer to use a single variable to store a recordset and then, using the content of the recordset, selectively update ...Show All

• Visual C# vs 2005 not responding

  I am using VS.Net2005. Whenever I open a project, the VS gets stuck. If I end the vshost process, the VS continues to respond (but I cannot debug the app). The same happens when I create a new project, so it is not a project specific issue. Does anyone know how to solve the problem thanks. Thanks for the call stack. Apparently the hosting process is failing very early, leaving Visual Studio in a deadlock condition. What we need now is a call stack of the hosting process itself.
