• Visual C# starting with graphics

  hi, i was trying to start with graphics, i tought it would be something like: // form1 declared by default in project, then, somewhere else: canvas_oranyothersimilarnamedeclaredinnetframework=form1.getcanvas(); newpen=graphics.pen(someatributes); canvasetc.gotoxy(x, y); canvas.lineto(otherx, othery, pen) or something like that. in the dafault documentation (visual express), i can not find any examples about things like that, i see only one example that may be related (how to draw a non rectangular button), but in this example: 1. i can not compile it by just copy paste, the 'click handler' is out of the braces of both clases, both form1 and public class 'mybuttonobject', there are things like Graphics ...Show All

• SQL Server Where is Auto Save in SQL Management Studio???

  I've done this twice now, I loose my sql script because I inadvertantly shut down management studio and a frantic click of buttons I do not click save! (yes I know, user error). What I am looking for is a function like in Microsoft Word where it saves your current document periodically. Where do I set that in management studio so I don't loose my scripts and that my changes are saved X # of minutes Regards, Matt Does Word's auto-save feature keep the interim files after you close and choose, "no, do not save my changes" I believe the only time when those files are kept around is when the application crashes. In your case, Management Studio isn't crashing, is it If you'd like to see ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. MDX or XNA i don't understand which to use!

  I first started MDX programming about a year ago, to create a simple 3D viewer app, after creating the app, I stopped and didn't touch mdx at all since then so i have forgotten quite a bit of it. Anyway I was suprised to find that mdx seems to be phased out and this new XNA thingy is replacing it. Is XNA just for games on xbox360 I am not interested in xbox360 or games programming, only programming 3D visualisation apps for windows pcs. I don't know if I should still learn MDX or learn XNA, i don't want to learn something and just have it phased out again... Any advice would be appreciated. ='( My app isn't very complicated, but native DirectX and C++ is not something i'm too keen on using for what will be ...Show All

• Software Development for Windows Vista When will SideShow drivers be available for my Windows Mobile 5 device?

  I'm dying to run SideShow gadgets on my WinMo 5 pocket pc. When will drivers be available and will there be any hardware-related restrictions on what type of gadgets will run Thanks, Scott Hi Scott, The Windows Driver Kit has some excellent samples to help you get started on writing your own SideShow drivers.  With the new User Mode Driver Framework it is now much easier to write your own drivers. As for hardware restrictions.  There shouldn't be any at all.  It really all depends on how much of the specification you (or the 3rd party) is willing the implement.  Standard SCF gadgets don't require any complicated transfers so sending via Bluetooth/WiFi is simple enough. With any SideShow implemen ...Show All
