• Visual C# GDI form transparency problem

  I'm trying to draw a transparent form using GDI, by overiding the OnPaint and OnPaintBackground event handlers. This technique works well enough on the first draw,and it produces a nice result, however, on subsequent draws, it works less spectacularly. For some reason, the screen is never cleared, and when it redraws the new things are composited ontop the previous draws, making the transparent images darker and darker. Here is the contents of protected override void OnPaint(PaintEventArgs e) { Graphics g = null; Assembly assembly = Assembly.GetExecutingAssembly(); Point point = new Point(400,400); backBuffer ...Show All

• Visual Studio 2008 (Pre-release) Data Binding and Threading

  I am data binding XML (XmlDataProvider) to the Content Property on a Label. When the XML changes the Label is updated. This works if the Xml is updated on the UI thread(I used DispatchTimer). If I use a worker thread (Thread.Timer), the label content does not update and I do not get any exceptions. I can get things to work if I use Dispatcher.Invoke and update the Xml in the delegate. Is ther a way to update the Xml on a worker thread without having to invoke I will post my code below.

• Visual J# Rebuild Issue with Object Test Bench

  I am able to create an instance of a class in the Object Test Bench.  But everytime I attempt to invoke a method (even an empty void method) of the class, the tool asks me to rebuild it, after which it resets the class and does not execute the method.  It does this even though I have not modified the code in any way.  I try to execute the method right after I create the instance. This seems to happen if you have multiple projects in a solution.  Is there a workaround Help! :) Steven Just for your information. I was having the same problem and changing the settings in the optio ...Show All

  I need to execute a SSIS package from a ".vbs" file on a computer that don't have SSIS installed on it.

If you can find a way of doing that in a .vbs file then you're laughing. -Jamie ...Show All

• Visual Basic Good articles on event handling in VB.NET

  I've started moving in to more advanced VB and I am presently having a look at event handling. I have tried to find some good resources on Google but event handling in VB.NET doesn't seem to be the stuff that people write about. On of my main questions is about the difference in event handling between C# and VB. Is it my perception or is event handling in VB a lot more basic I would appreciate it if anyone could point me in the direction of a good web resource or a book on event handling in VB. Thanks jjrdk I've been digging into the subject and have stubled across a major obstacle when implementing even ...Show All

• SQL Server management studio object search

  Query Analyzer has the object search tool - F4 to access. Is there a similar tool in Management Studio I have looked around and been unable to find it. Thanks, RM I've tried SQLDBSearch it works fine and "Search by SQL definition (text)" feature is very cool, thanks to the author. However if you still like Object Search tool (Shortcut F4) you can point your Query Analyzer to an instance of SQL Server 2005 it works fine for me. I'm wondering why SQL Server team did not keep this feature in MMS and I hope the tool will be reintroduced in next release. ...Show All

• SQL Server TEMPDB System Database

  Hi, There is a strange problem happening. I have MSSQL Server 2005 setup on a new computer. By default, this has created the system databases on the system. I have added 2 of my own databases.

• .NET Development Why Two Installers For Windows Service?

  One of the review questions in a C# MELL is: Why do you need to add instances of both the ServiceProcessInstaller and ­ServiceInstaller classes to install your service application This is a good question and I am unable to answer it.  The MELL gives the following in the "Answers" appendix: A service application can contain more than one service. The methods of the ServiceProcessInstaller class perform the tasks that are common for all the services within a service application, such as writing entries in the system registry for all the services within the service application. The ServiceInstaller class performs tasks specifi ...Show All

I tried calling my EventInfo's GetRaiseMethod but it simply return nothing. How can I do this   Thanks TheGetRaiseMethod returns null for all events declared with the event keyword as explained in the MSDN help for the same. The documentation apparently is not as verbose as it should have been and we will work on that. The GetRaiseMethod will return the method that was set through SetRaiseRaise method if you generate a method dynamically. If you need more help in this please ...Show All
