Microsoft launched a tech preview version of its Mesh application last week.
I was trying to add my Vista machine to the Mesh by installing the client app, but keep getting a message, some thing like "This application can be installed on 32-bit US version of Windows XP and Vista".
I could not figure out what went wrong for the past 3 days, almost tried everything I could think of, even wanted to uninstall Vista SP1 . Finally, 10 minutes ago, I tried to set my location to US, and all things worked!
Thought this might be helpful for other people.

In .NET Compact Framework, Graphics.MeasureString only measures the required width and height for a single line string. What happens if the text is wrapped?
Several years ago, I used this piece of code to measure a wrapped string height. Not pretty, but works. A couple of days ago, I found this code, which utilizes the DrawText API, I think is better, but I did not like the idea of taking a control as input. Combine these two, I have this code:
static public Size MeasureStringEx(Graphics gr, string text, Font font, Rectangle rect)
{
RECT bounds = new RECT();
bounds.left = rect.Left;
bounds.right = rect.Right;
bounds.bottom = rect.Bottom;
bounds.right = rect.Right;
IntPtr hFont = font.ToHfont();
IntPtr hdc = gr.GetHdc();
IntPtr originalObject = CoreDll.SelectObject(hdc, hFont);
int flags = CoreDll.DT_CALCRECT | CoreDll.DT_WORDBREAK;
CoreDll.DrawText(hdc, text, text.Length, ref bounds, flags);
CoreDll.SelectObject(hdc, originalObject);
gr.ReleaseHdc(hdc);
return new Size(bounds.right - bounds.left, bounds.bottom - bounds.top);
}
and the CoreDll API imports:
Public struct RECT
{
public int left;
public int top;
public int right;
public int bottom;
}
[DllImport("coredll")]
public static extern IntPtr SelectObject(IntPtr hDC, IntPtr hObject);
[DllImport("coredll.dll")] public static extern int DrawText(IntPtr hdc, string lpStr, int nCount, ref RECT lpRect, int wFormat);
public static int DT_CALCRECT = 0x00000400;
public static int DT_WORDBREAK = 0x00000010;
