• SQL Server adding dbo to db_owner

  Im duplicating a database by running the script below. This works fine. My only problem is that the dbo user does not by default have any role memberships in the new database hence no access. I have tried using sp_addrolemember but dbo is not a valid user for this procedure. Adding dbo to the db_owner role through the sql2005 MS works fine, but I would very much like to script this.

• Visual Studio Accessing IVsTextLayers?

  Hello, I'm trying to support word-wrap and folding/outlining better and with better performance in my vi/vim emulation addin. In order to do this, I'm trying to access the different layers in an IVsTextView directly. I've been successful in getting the 'topmost' layer (IVsTextView -> QI(IVsLayeredTextView) -> GetTopmostLayer() -> IVsTextLayer), but I can find no sensible way to get the next layers. The real need is to get to the layer that comes before word-wrapping, which I'm guessing is the last layer. I'm guessing there is one or more layers that applies the outlining/hidden regions. Accessing this layer, I can quickly map buffer coordinates to non-word-wrapped-but-outlined coordinates. The only thing I've found that return ...Show All

• Windows Forms font.Height and Graphics.MeasureString failing on user machine?

  I have a Forms app that prints reliably on my laser printer but fails on a user's Zebra thermal printer. Filling my code with exception logs shows it throwing System.ArgumentException whenever I try to use the Font.Height property or Graphics.MeasureString on the same font. To help track this down I borrowed the user's printer, installed his driver on my development machine... and it works fine. Any suggestions as to what could be going wrong, or other things to check Looking at the Font.Height property implementation, I see no code that could throw ArgumentException, just ArgumentNullException and one of the many GDI+ exceptions. Can you post a snippet of the code that throws on your customer's PC ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Garbage Collection

  Hi. I'm not a game programmer yet but I'm a programmer. I have been learning computer graphics (opengl) at school and while I was talking to one of the professor was referring to Java as the main problem is that the garbage collection does not permit it to be real time. I know that the .net framework which I use quite often has garbage collection as well. The problem with garbage collection is that you (the programmer) does not know when it will happen. My question are 1) Is Xna going to have garbage collection and 2) if it will have garbage collection, wouldn't this make a video game slow thanks Francisco Shawn Hargreaves wrote: ]A lot of the code for Unreal Engine games is written in a scripting la ...Show All

• Visual Basic MessageBox.Show doesn't works in Win2003 ED. Why?

  Hi everyone, Primary platform is Framework 2.0. We're suffering an odd behaviour for an UI code. We've built a Windows Service by means of VB and everything goes fine. OnStart method and another ones we've defined a MessageBox.Show function in order to show errors or whatever to the users but unfortunately they don't see at all. Curiously it happen only in our server (Windows 2003 Enterprise Edition) no in a Windows XP Pro workstation. Does anyone ever faced this issue According to BOL is not recommendable to show UI in that kind of projects but "only not recommendable". Thanks for your time, I don't think it is a good idea to use messagebox for a windows service. Windows services shou ...Show All
