We're now trying to host the WinForm User Control (with the embedded WWF Designer) in an ASP.NET page using <object> tags.

• Software Development for Windows Vista Vista 5308 refuses to activate. Any way to retrieve files?

  We upgraded a windows XP machine (non-domain) to Vista 5308 recently. Upon trying to activate we kept getting an activation error 0x8007000 "Data is invalid". It only once came up with an option to activate by phone. However when the form came up, the activation codes that normally appear for you to read to the automated system were blank. We had forgotten about the issue for a few weeks as other development issues had taken precedence. Upon revisiting the machine yesterday, it had said that we had to activate, the period was over. We attempted to activate again and received the same error. "Data is invalid". There is ...Show All

• Visual Studio Express Editions Newb Question: Opening Forms inside main form

  I'm completely new to programming, my knowledge only goes as far as html, css and light php so I'm way in over my head. :) I've been through the tutorials but all the teach is how to pop open a form in a new window. I need it to display as though it was seamless. I've created Form1 and I want to use that as the main design of everything. What I need to do is open up all other forms created inside of Form1. For instance, if someone clicks on the button Add New Customer, it opens up ( inside the main window to the right) the New Customer Input box to start them on the process of adding information to the db. If they click "Pay on Account ...Show All

• .NET Development Dynamically create a proxy or call a web service from a WSDL.

  Hi, How can I dynamically create a proxy or call a web service from a WSDL. I need to call a variable number of web services which all implement a known method.

• SQL Server Designing Aggregations

  I have a fairly large partition (100M rows, 30 measures) and am attempting to create aggregations through the Aggregation Design Wizard.  Regardless of the option I select, either percent or file size, the wizard always completes after designing only about 50 aggregtions for 0% and only 200kb.  I cannot believe that to be right.  On a much smaller partition I created about 600 aggregations to 30% for 2GB. I've double checked to ensure I have all of my dimension attribute relationships defined.  Any ideas why I cannot get the large partition to build the aggregations or why it completes after building about 50 & ...Show All
