It sounds like this might clear it up for you:
public class Externs {
private Externs() {
}
// used to reset FP register to default state as per
//
http://support.microsoft.com/default...en-us%3B326219
// If FPR not in default state initing fonts in controls can fail.
// _CW_DEFAULT should be the first arg, and 0xfffff the second
[DllImport("msvcr70.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern int _controlfp(int n, int mask);
// definitions taken from FLOAT.h
public static int _CW_DEFAULT =
0x00000000 + 0x00000000 + 0x00000010 + 0x00000008 + 0x00000004 + 0x00000002
+ 0x00000001 + 0x00080000; //( _RC_NEAR + _PC_53 + _EM_INVALID + _EM_ZERODIVIDE
+ _EM_OVERFLOW + _EM_UNDERFLOW + _EM_INEXACT + _EM_DENORMAL)
}
Use it somewhere in your startup before creating the form as so:
Externs._controlfp(Externs._CW_DEFAULT, 0xfffff);
HTH!
