• Visual C++ DeviceIoControl does not work when query LCD brightness

  Hi, All I wrote a test program to get/set the LCD display brightness. I followed instructions on MSDN as http://msdn.microsoft.com/library/default.asp url=/library/en-us/power/base/ioctl_video_query_supported_brightness.asp but it seems that DeviceIoControl with IOCTL_VIDEO_QUERY_SUPPORTED_BRIGHTNESS always fails and GetLastError() reports error code 2: system can not find the file specified; If I call DeviceIoControl with IOCTL_VIDEO_QUERY_DISPLAY_BRIGHTNESS, it succeeds but the number of bytes returned is zero. I don't know what is wrong. Can anyone explain why Thanks in advance. Chris below is the code of the test program: -- ...Show All

• Visual Basic Cross-thread operation not valid

  Please tell me that you are going to fix this before the official release!! I am using VB not C++.  I really shouldn't have to care that my code is not running in the same thread as the one that created the form that contains the control that I am trying to update. Please fix this or at least have some real examples that show how to update a control on a form.  The examples that I found were not helpful at all. or, you could just set ystem.Windows.Forms. Control .CheckForIllegalCrossThreadCalls = false and all your cross threading problems go away. ...Show All

• Visual Basic Using sender as a case in Select Case Statement

  When my form loads it adds some handles (using AddHandler ) to a sub ( showStatus ). What this sub does is checks which control activated the sub (using sender.Equals ) and displays text in the status label ( status ) accordingly. For this I use an If...Then statement for each possibility. There are many possibilities and my code get cluttered. Is there a way to do the same thing with a Select...Case statement. I tried: Select Case sender Case tbOne : status.Text = "blahblahblahblahblahblah" End Select where: tbOne is a textbox, status is a StatusLabel It gives me an error though, saying " Operator '=' is ...Show All

• SQL Server using ssis to generate load

  hi. i'm trying to use ssis for something it wasn't meant for (i think)...  which is load generation. I have a table which has exec sql statements. I want to load this table, multicast the statements into x recordsets, then get x sql connections and execute these statements. so far i can load the table, and multicast it into x recordsets. But i can't figure out how to execute these statements by getting them out of the dataflow and into control flow 'execute sql' task.... i'm i on the wrong path thanks!   PugV wrote: yes, the number of statements is known..  No problem then ...Show All

• Visual Studio Team System Is there a way to check Modified Code only?

  I don't know if this is possible at all.  However, I'm using fxcop with CruiseControl and have been looking for a method to only check new code for violations. We have an older system which has a large amount of legacy code which probably can not be refactored for the time being. However, I want to ensure that developers are checking in fxcop approved code.  And have a large list of issues is making this job rather difficult. I must manually view the files that they have altered to determine if they have checking in proper code. So is there a way to tell fxcop to only check modified files or even modified pieces of code only ...Show All

• Visual Studio 2008 (Pre-release) DLinq and NTEXT columns

  I know SQL Server is deprecating them (someday), but the following currently does not work... CREATE TABLE Thing ( Id INT, Title NVARCHAR(200), Description NTEXT -- Change to NVARCHAR(MAX) and this will work ) [Table] public class Thing { [Column] public int Id { ... } [Column] public string Title { ... } [Column] public string Description { ... } } Try to update an instance of Thing... UPDATE [Thing] SET [Title] = @p3 FROM [Thing] WHERE ([Title] = @p0) AND ([Description] = @p1) AND ([Id] = @p2) [...] which leads to SqlException "The data types ntext and nvarchar are incompatible in the equal to operator." ...Show All

• Visual Studio Express Editions Managing exceptions in a backgroundworker

  Hi, I'm using a backgroundworker (in VSE2005 for C#) and have the following problem : In the 'dowork' method I have a try/catch that handles exceptions that might occur and then rethrow them for the 'workcompleted' method have a proper error state. The problem is that when an exception occurs, I get an unhandled exception error message pointing to the 'throw ex;' in the catch block (see code below), because of course ex is not being handled, at least not right there. The problem is that in order to test for the error status of you background _dowork method in your 'workcompleted' method you rely on the RunWorkerCompletedEventArgs ...Show All
