char x1 = (char)153;
char x2 = 'Ö';
char ss1 = System.Text.Encoding.GetEncoding(850).GetChars(new byte[] { Convert.ToByte(x1) })[0]; //x1=153 result 214="Ö": ANSI code
byte b1 = System.Text.Encoding.GetEncoding(850).GetBytes(new char[] { x2 })[0]; // x2=214 result 153 Code-Page code

i want the value 153 if i use the character (char)153 and alt+153.

// Set two ecodings for convert
Encoding unicode = Encoding.Unicode;
Encoding CodePage850 = Encoding.GetEncoding(850);

// Test character
// Alt+153 with 214 char code on unicode
char c1 = (char)'Ö';
// Convert 214 from Char to array.
byte[] ub1 = Encoding.Unicode.GetBytes(new char[] {c1});

// convert char code 214 from unicode to CodePage850, with a char code 153.
byte[] ub2 = Encoding.Convert(unicode, CodePage850, ub1);

Pngs can be made in 16 bit color depth format so there must be some app/platform that supports their rendering.

I saw some stuff on using "textures" to emulate 16 bit detail. One reference alluded to Directx but gave no details.

Manual and AutoResetEvent derivations are just conveniences that give clarification of intent and self documentation of code.
