• .NET Development Activator.CreateInstance

  I'm not sure if this is the right group for this post... but here it is. I have a set of assemblies that are built against a common interface. At run-time I use Activator.CreateInstance to load up whatever assembly I want, as long as it conforms to that interface. The loading of these interfaces is done through a web service. So the chain goes, user calls web-service, web-service decides which assembly to return, use Activator.CreateInstance to load the assembly and execute the predefined interface methods (Start(), Implement(), Finish() -- example). The problem I am encountering is with the MSCRM 3.0 Web Service which resides in one of these assemblies that gets dynamically loaded. When I run through the above call chain, the MSC ...Show All

• Windows Forms Binding a textbox to a database field using TableAdapters

  Hi there, I'm trying to bind a ASP TextBox to a certain field of my database using a TableAdapter. It's quite easy to bind the result to a DadaGrid: ProductsTableAdapter productsAdapter = new ProductsTableAdapter(); GridView1.DataSource = productsAdapter.GetProductsByCategoryID(1); GridView1.DataBind(); But how can I bind a certain Column to a TextBox I thought something like this would be possible: //Get the Adapter ProductsTableAdapter productsAdapter = new ProductsTableAdapter(); //Get the result of the whole query Products.ProductsDataTable data = productsAdapter.GetProductsByCategoryID(1); //Get one Cell out of the result myTextBox.Text = data[0].myProduct.Value; Can anybody asist me on this Thanks, Finch. ...Show All

• Visual Studio 2008 (Pre-release) DirectionalLight and different materials

  Hi! I am trying to make an animated 3D model of the solar system. I am having problems with lights and materials. Is it possible to make a object that emits the light (directional) For now I am using only sun and earth. I am using DirectionalLight to make earth visible but I don't want the sun to be enlightened by that light. If I use only EmissiveMaterial for the sun it looks OK, but when the earth should go behind the sun it appears in front of it. Is this a bug It looks like a bug. If I change only the material of the sun the earth goes behind it as it should. But DiffuseMaterial is enlightened by directional light and it does not look like the sun any more. Does anybody have an idea how could I achieve the proper li ...Show All

• Windows Forms WebBrowser doesn't have a "find" method?

  Hey, I'm a novice here and I've been looking though the MSDN documentation on the WebBrowser control and noticed there was no method for finding text in a document. This is a pretty serious omission. Is there a way of getting this functionality Anyone know of a method that does this Apple's WebKit has a method called stringByEvaluatingJavaScriptFromString that essentially does this, so I'm hoping MSHTML has an equivalent... ...Show All

• Visual Studio How to write text to a console from a web application on the server

  Hi all, Are there any ways to debug a web application with VS2005 on the server by writing text to a console like J2EE web app I read an article about using a listener with either trace or debug objects to write text to a console but I could not make it work. Please help if you know how to do it. Regards, JDang Hi Peter, Thanks for you email. For now, I just want to debug with ASP.NET 2.0 only. I have not tried to use VS2005 to debug the website remotely yet. If you have any information about how to do that, I really want to learn too. I tried to turn the trace flag on a webpage on, but I did not like that technique since the user has no ideas about what is going on. I hav ...Show All

• Software Development for Windows Vista Passing output parameters to the host?

  Tom, I am using XOML only state workflow from ASP.NET client (WF 3.0).  I need to pass output parameter to the host ASP page before WorkflowCompleted event executes. Can you and/or someone please provide a code example of how this could be done Thanks in advance, John Portnov You can't actually get output parameters until the workflow completes. If you want to get intermediate values of workflow properties, you'll need to use tracking. With tracking, you have two options - you can use tracking extracts, which will essentially pull out values of properties when certain events are tracked, or you can use user track points inside your workflow to track custom events with the values of your properties. You'll h ...Show All

• .NET Development How to play MP3 file without WMP?

  Hello.How I can make my app to play mp3 files without using Windows Media Player.What I need to learn YOu need to learn how to write an mp3 decoder, and then you need to pay the licencing fees associated with writing code that uses that algorithm. Then you need to learn how to write the results direct to the sound buffer. Sounds too much like hard work to me, especially as the world sure doesn't need another MP3 player. Sounds like fun, tho, if you're into deep maths and have a lot of time on your hands. ...Show All

• Visual Studio 2008 (Pre-release) Rubber Banding

  Howdy, Ian G did a blog article back in 2004 on rubber band selection in WPF http://www.interact-sw.co.uk/iangblog/2004/02/06/rubberband that showed how to do this by placing a rectangle in the visual tree at an appropriate level. Is this still the way to go Or is there a different preferred method Thanks Paul After months of searching I've concluded that for Windows.Forms (VS2005 [VB]): 1. MSFT "Adorners" provide Control grips in the VS2005 UI for design-time use, not for user interface at run-time. 2. With some difficulty I've written my own VB code to provide re-sizing grips on my controls for run-time use (re-inventing the wheel). 3. For VB rubb ...Show All

It does tell me the name of the database. Index Usage Statistics Shows how the users and system use the indexes.
