• Visual Basic Runtime compilation / CodeDOM

  Hi, Question: Is there a way to dynamically add properties to a class at runtime Background: I'm trying to write an app that lets a user write some code in a text editor at runtime, and then compile and run the code. Compiling and running the code is no problem using the CodeDOM classes, but there's somethign else I'm trying to achieve. I'm using an editor that provides code completion (CSharpEditor, though I might end up using VSTA) and what I'm looking to do is dynamically add properties to a class. For example, a line of code (at runtime) might be: Dim Bob as new DataObject(someParam) If I then type Bob DOT then I see a code completion window with each of the properties of the DataObject (name, email, address etc.) However, I also have ...Show All

• Visual Basic Disabling sound for a control and/or application?

  Greetings. I'm writing a vb.net 2005 application which has hidden webbrowser controls in it, in order to retreive data from a website. The problem is that these websites have flash advertisments with music and sound, and I need to disable that sound so that people don't suddenly start hearing noises and not understand where they come from. Is there any way I can disable sound for the webbrowser control, the form, or the application - without completely muting off the computer Thanks in advance, -Elad Start + Run, regsvr32 -u c:\windows\system32\macromed\flash\flash.ocx If that doesn't work, restore the flash player by repeating the same command but now without the "-u" option. ...Show All

• SQL Server Am using sql server 2005, column data type is varchar, how to write a query to sort

  this data. need help Sort following numbers by asc and desc order Before query sort -1.1 -8.8 -15.5 0.0 +0.5 +0.2 Sort asc +0.5 +0.2 0.0 -1.1 -8.8 Sort Desc -8.8 -1.1 0.0 +0.2 +0.5 Why are you storing numbers in varchar You can do a CAST(varchar_col as decimal( , )) with appropriate precision/scale and sort on the expression. select * from tbl order by cast(varchar_col as decimal(10,4)) -- or select * from tbl order by cast(varchar_col as float) But this is also ugly workaround. If you have data that cannot be converted successfully to decimal/float the query will fail. You can use ISNUMERIC but that checks for more formats and you may still get runtime errors depen ...Show All

• SQL Server selecting from a SP

  Hello How can I select from an output of SP . I have created to SPs, say myProc and myproc2 to test this: CREATE PROCEDURE dbo.myProc AS begin select * from STOCKS end GO CREATE PROCEDURE dbo.myproc2 as begin select sto_id from myProc end GO When I run myproc2, I get an error: "Invalid object name 'myProc'." If myProc produces a table, so why can't I select from it Hi, You might consider using Functions in stead of stored procedures. These can be included in the From clause.

• Game Technologies: DirectX, XNA, XACT, etc. collision detection with backbuffer

  Hi, i am new at gamedevelopement so... i am trying to do a collisiondetection method over the backbuffer. I am trying to make a 2d game with 3d objects (not sprites because the objects with light and so on looks much better) and couldnt make a very exact collisiondetection. I had the idea to use the backbuffer data with renderTarget2D class and make different layers (wich are not rendered) in which i could detect pixelcollisions between the 3d models on my screen (between their shadows for example) after i check collision before with boundingBox or boundingSphere. Because i am new to this stuff, my first question is: Is this slowing the game very much Or is this the worst method to detect collisions between Objects Tee ...Show All

• SQL Server Accessing Reports through a web application??

  Hi All, I have developed few reports in SQL Server 2005 Reporting Services and deployed them on a reporting server. These reports are accessed through a web application that is deployed on a different server. I am using the Report Viewer control in my web application. The problem is when I access the reports through my web application, it gives me a Page not found error. If I have both web server and reporting server on the same machine, then this problem does not come. I need to have separate web and reporting server. Can anyone please provide help on how to solve this authentication issue. My web application is taking the credentials but the credentials are not getting passed if the reports are deployed on a different serv ...Show All

• Smart Device Development Capture Outgoing dialled number

  Hi, I tried searching on this but was not able to find a way to capture the outgoing called number using SNAPI.

• Windows Forms What is faster: GDI+, Direct Draw or OpenGL for 2D drawing of 250,000 lines?

  Hi, What is faster: GDI+, Direct Draw or OpenGL for 2D drawing of 250,000 lines Thank's Alexei First off I would mark directdraw from the list as this has been depreciated and the functions have been replaced inside of the direct3d classes. Next it will depend on other factors, will the app need to be cross platform, if not I would have a look at using direct3d for the task. OpenGL would be able to do the task but there is no real support for managed languages, you have to use 3rd party wrappers to do the job. Here is a link to some opengl resources that I have collected http://www.ircomm.net/forums/587/ShowPost.aspx . Hope this helps. ...Show All

• Visual Studio Team System TFS says KB913393 is not installed when it is

  Hi, I am trying to install TFS on a single server running Windows 2003 R2. Setup reports that ASP.NET 2.0 QFE KB913393 needs to be installed. However, I have now installed KB913393 several times and it doesn't appear to make any difference. When I run the KB913393 setup I see a message asking if I want to install the Hotfix. I then see a Licence Agreement screen followed by a progress bar as something is installed. However, I don't see any further messages to say the hot fix was successfully installed. Maybe this is normal but TFS setup still reports that the hotfix needs to be installed. Any help would be greatly appreciated as this is driving me mad :) Thanks, Aaron Hi Matt, I did eventually get it installed and i ...Show All
