• .NET Development How could I know if I am running a NGEN'ed image?

  After I NGEN'ed my program and run it, I found there is no change on memory cost and running speed. I doubt if I am still running the old version(not NGEN'ed) of my program.

• Visual Studio Express Editions I need help

  Hi my son Brent is wanting to learn how to program he is only 15 but knows alot about computers. What would be the best way and best programming laguage to learn. Also is there ne programming schooled that he could go to and how old do you have to be. Thnx Stacy The hardest thing about learning programming is learning the basics that apply to all programming languages.

The answer really depends on how committed Brent is to programming and how he best learns things. My basic suggestion is for Brent to learn some math if he hasn't ...Show All

• Windows Forms I don't even know where to begin on this one...

  I have a very large (enterprise) application I'm developing in VS.NET 2005 RC1.  The application is based around a number of services (a lot like the Microsoft Composite UI application block).  Within the application I have a number of forms that act as Wizards.  This is where the problem begins.  The first time through the wizard everything works perfectly (there are a number of comboboxes being bound to data, etc.)  Once the wizard is closed and then opened again none of the comboboxes will display anything.  The databinding seems to happen correctly; if i set a breakpoint, intellisense shows the combobox with ...Show All

  Am I the only person in the world that has noticed how awfully VB.NET renders fonts on controls ! The only control that appears to render them in the same fashion as they would appear in Word or Internet Explorer or whatever is the Tab control. Every other control misdraws the fonts and introduces all sorts of loony kerning. It really makes for an UGLY UI. Is there some workaround for this ...Show All
