Here is the old HangMan example (http://www.movsd.com/board/index.php?topic=17936.msg151118#msg151118), demonstrating how to use Locate(x,y) in console mode. Another simple example:

include \masm32\MasmBasic\MasmBasic.inc   ; download (http://masm32.com/board/index.php?topic=94.0)
   Init
   .Repeat
      Let esi=Input$("What's your name? ", "RHL")
      .Break .if word ptr [esi]!="HR"
      Print "I asked for your name, not your nick!", CrLf$
   .Until 0
   Inkey "Hi ", esi, ", how are you?"
   Exit
end start

RHL,

You can read the console output buffer, but only for your console screen, not an arbitrary console screen. See the API for GetConsoleScreenBufferInfo.

It basically boils down to

Code: [Select]

invoke GetStdHandle, STD_INPUT_HANDLE
...
invoke SetConsoleMode, eax, ENABLE_LINE_INPUT or ENABLE_ECHO_INPUT or ENABLE_PROCESSED_INPUT
...
invoke ReadFile, hInput, pBuffer, bLen, ADDR bRead, NULL
