• Software Development for Windows Vista Custom Activity - Probelm with EventSink Activity

  Hello, i tried to model a custom activity. This activity does contain of a) InvokeMethod Activity b) EventSink Activity out of the activity galery delivered. I also implemented a Service which I added to the workflow engine in order to connect the method invokation and the event sink. Then I build up a sequntial wf out of my custom activity. The method invoke activity within my custom activity works properly, but when my async. operation is finished and I want to raise the event to trigger the eventsink activity the event within the added service was null. The same scenario works fine when i model this directly within a sequential wf. Regar ...Show All

• SQL Server Ignoring Source Field

  Hi, I am implementing a Transactional Replication btwn two SQL 2000 servers, which is using Data Transform services (DTS package) to manipulate the data. I need to ignore a source column from replication but that column field value needs to be appended with other field column. For ex. Let two source fields be named FirstName and LastName. In the target database i need to merge those field values into a Single field called CustomerName. Also i don't want the two source fields to be replicated in the target. I tried to ignore the field by unchecking the Column Transformation and Mapping screen, but then unable to append the ...Show All

• SQL Server Option for accessing external DLL's from the CLR

  What are my options for calling external DLL's from SQL CLR, I used to use the sp_OA method but these have been converted to .Net assemblies and I do not want to use interop for several reasons. Any suggestion would be greatly appreciated. J- Are the external DLLs .NET assemblies, or...   If they are not, interop is really your only choice (or turn back on object automation).  If they are assemblies, just load them into SQL Server (using CREATE ASSEMBLY) and go for it...   -- Adam Machanic Pro SQL Server 2005, available now http://www..apress.co ...Show All

• Visual Studio VS.NET 2003 reference

  I'd like to start writing some addins for Visual Studio but I'm not sure where to find trustworthy documentation. I've scoured msdn and don't really see anything other than topical information. I'm reluctant to buy the books that are out because the review stink. An example of some of the information I'm looking for right now is how to simply add a menu item to the HTML editor window.. or to all the windows (code, html, sql, etc). I have code like this: oCommandBar = applicationObject.CommandBars["Code Window"]; that adds to the code window but I can't find anything the explains anymore than this basic type of stuff.

• Visual C# Digitally sign a c# web form from a CaC (smart card)

  Does anyone know how or does anyone have some sample code on digitally signing a web form Right now we have a manual process on our network accounts. Someone fills out the form on the web, prints it and then faxes it to us. I'd like to make this as automated as possible. Thanks, Frank Hi, Thanks for your posts on MSDN forums. Basically, it doesn't make sense to sign a web form in your source code, for the security check is based on binary data transfer. And it's highly suggested you enable SSL of your server's iis setting after you request a verisign certificate to public at: http://www.verisign.com . It ...Show All

• Visual Studio Express Editions Console applications output

  I plan on making a program which uses various console applications. I was wondering whether there was a way to make the console text output show up in a second window or picture box of the GUI I am making. Hi Drak, I played with this abit and not exhaustively, but what I saw was highly discouraging. I made a console task and attemtped to import system.windows and created and instantiated a form. No matter what I did, I was unable to invoke that form so I'm pessimistic about this. I think at best you're going to have to go to a two processes an do interprocess communication.

Normally you use \n which maps properly ...Show All

• Software Development for Windows Vista Vista UI lacks of Transitions, Fades and some other things

  I like Windows Vista very much, but when i compare the current December CTP [of which I am beta tester] with a Mac OS X Tiger video found on the apple homepage, Vista falls behind in some areas. What I find so pleasing in Mac OS X are the cool but not annoying transitions in various parts of the user interface. In Vista, except of the window minimize to taskbar, maximize from taskbar, window open and window close effects, there are none noticable. There should be much more, for example when opening the start menu, etc. There are tons of possibilities for transitions which look nice,  aesthetic, don't disturb users and help better recog ...Show All
