• .NET Development Support for E4X anytime soon?

  Is support for E4X coming to JScript anytime soon I'm guessing no since 2.0 of the framework is about to roll out and it's not in there yet. E4X features will not be in the Whidbey release of JScript .NET. There is also no plans to add it for the next release of the COM classic version of JScript (IE7). At this point, we're evaluating how much customer demand there is for the feature set. What scenarios would you like to use E4X ...Show All

• Visual Studio 2008 (Pre-release) Table Width in a FlowDocument

  The table always stretched to the whole document width, but i need fit table to it's content (or set width explicitly). How Unfortunately, there's no way to make your table size to content horizontally  in V1.  If you don't have much data, you can use a Grid within a BlockUIContainer, or even a Figure or Floater. For example: <FlowDocument>   <Paragraph>From the data, we notice that strawberries really do taste better than chocolate:     <Floater>       <BlockUIContainer>         <Grid /> ...Show All

• Visual Basic Internet and ADO

  Hi all, I had a VB6 program that opens a remote asp page as an ado recordset. The asp page connects to the remote db, gets some records and return them. Should I do the same in .Net or is there a better alternative to retrieve data from a remote db. Note: webservices are not an option Thanks, Ivan Hi Ivan, Did your Database is exposed on the web e.g. We can install SQL server at machine A, but our client at machine A can connect to it directly. If no, we have to build an application which will retrieve data from the DB and pass to the client. For .NET, we can do that in ASP.NET, but if you ...Show All

  Hello, I'm writing a WCF application using Indigo Beta 2. I have created a service which listen on http address using wsHttpBinding and a client which create a proxy using ChannelFactory<> class. Everything works well except that I want to find the client address (client machine name) which send the message.

• Software Development for Windows Vista InvokeWorkflow Dependecy .

   Hi there, I have a question about the dependency of the invoke workflow activity, how can I make the child workflow is dependent with the parent workflow, i mean that the parent template will stop processing until the child template is finished. Thanks WWF team. BaselN, The InvokeWorkflow executes the child workflow asynchronously from the parent. If you're looking for synchronous behavior, the child workflows should be designed as custom activities instead. That way, they can be dropped directly into the parent workflow.

• Smart Device Development How to open/close GPRS connect?

To deliver string from smartphone and show it on PC is my current task. However, I can do that via USB connection but failed in GPRS. It seems to mean that both programs in client and server are correct but something wrong in GPRS connection. Maybe I need to write a program in C# to start GPRS connection. However I could not get any information about GPRS connection in the MSDN for C#. Would you please do me a favor to give a example program or tell me what function or structure could accomplish ...Show All
