• Visual C++ How do you set the name of a thread in C++?

  This is something that I've been able to do in linux development, but I have not figureed it out in Visual C++. I've noticed that the thread list contains names, however they are always the same and I cannot seem to find the way to name them. This is not an MFC application. Currently, I'm using _beginthreadex to create the thread. I've tried a few things here... 1. Immediately after CreateThread(...), call SetThreadName(...). This doesn't seem to have any effect. The name reverts back to the name of the supplied ThreadProc, so I'm assuming either the debugger doesn't know about the thread yet, so ignores the exception, or it is overwritten when the thread starts. In this case, the thread ID I'm using is directly back from the call to ...Show All

• SQL Server Ad hoc updates to system catalogs are not allowed.

  in SQLServer2005 how can I allow update system catalogs (by mouseclick) sp_configure 'allow updates' , 1 - works, but I get the message Msg 259, Level 16, State 1, Line 1 Ad hoc updates to system catalogs are not allowed. All these answers are great workaround-coverage for not allowing ad hoc updates to the catalog tables. And I can see some reasoning behind not allowing DBAs to get their job done in an efficient and expedient manner. But this is just another example of executive thinking --and decision making-- by MS. My case is hundreds of databases and no way to use the wonderful method of set processing to get the job done. Now I am begin told if I want to set the status of a hundred databases from 'Full' to 'Simple' ...Show All

• .NET Development How can I have one and just one copy of my application running in the same time???

  How can I have one and just one copy of my application running in the same time I did somethign similar a while ago; doing something like this is so popular that I blogged about it here: http://dotnet.org.za/ernst/archive/2004/07/20/2887.aspx What makes it neat is that, if an existing instance of your application is already running, it will bring it to the foreground and maximize it. With the inspiringly named "helper" class (linked to from this blog-post) you're able to write: public static void Main() { bool firstInstance; Mutex mut = new Mutex( true , strSystemMutex, firstInstance); if (firstInstance) { try { Application.EnableVisualStyles(); Application.Run(new frmLogin()); } catch (Exception ex) { Excep ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. I’m in desperate need of direction...

  I know you guys are probably overrun with these kinds of threads, and I apologize for making another one. I did my best to look around and get as much info from the other threads as I could, but really I need a personalized response to figure out what I should do. I’m 17 and am currently replying in the process of applying to my local college (game design and development), but stupid me forgot that they want a portfolio for classes like this (windows applications, small games, ect ect). And I have about 2 or 3 months to figure this all out before my portfolio is due. So far I’ve downloaded XNA game studio express, Microsoft Visual C# 2005 express, and the 30 day trial for the Torque game builder. I’m completely new to this and totally lost ...Show All

• SQL Server TIFF render quality problem

  The quality of rendering for reports in TIFF format is really nasty. Fonts are horrible. Is there anything we can do to improve the quality when rendered in TIFF format We had to change rendering type from PDF to TIFF because Acrobat Reader could not display the reports we were generating (apparently because of images). Thanks. Glenn. No. We get "A drawing error occurred" when attempting to view the PDFs. Searching the net has led me to believe that Acrobat cannot handle some images very well, especially if they have transparency. The images we embed in the report are not under our control, they are generated by MapPoint and another third party company. We sometimes have 10-15 ...Show All

• Windows Forms Slow in form display

  Is there any method to speed up the display and rendering of Windows Form In my application, my Windows forms containing around 50~150 controls. There are also some navigation button to hide one form and display another one. The delay occur during form showing up. As I'm developing a POS, such kind of delay is not preferable. Is there any workaround to speed this up Yes, once you get past about 50 controls or so, the cost of using .NET controls and their associated Windows window becomes obvious to the eye. Look into drawing onto a form with the Paint event rather than using a control to make the UI snappier. Labels are an obvious candidate. ToolStripItems are low-cost too. ...Show All

• Windows Forms Opacity - Fading screens

  I got some code from Planet-Source-code that shows how to use opacity. Strange thing is that some of my forms doesn't fade and some works beautifully. Code as follows Dim i As Single For i = 0 To 1 Step 0.01 Me .Opacity = i My .Application.DoEvents() System.Threading.Thread.Sleep(0) Next This Fades the screen in nicely. So i tried to change this a bit and removed the 3rd and 4th line. (My.Application... and System.Threading....) Now the screen fades in but it stays a black box until visible. This does also not work on all screens. The only thought that I have is screens that loads lots of information seems to not do this while screens such as a processing screen which only opens work ...Show All
