I am moving the HANDLE to output and HANDLE to input into two different variables. When i use those variables as the handle parameter to ReadConsole and WriteConsole, it doesn't work. Here is my code:
Thanks in advance.
I am moving the HANDLE to output and HANDLE to input into two different variables. When i use those variables as the handle parameter to ReadConsole and WriteConsole, it doesn't work. Here is my code:
Code:
.386 .model flat, stdcall option casemap :none include \masm32\include\windows.inc include \masm32\include\user32.inc include \masm32\include\kernel32.inc includelib \masm32\lib\user32.lib includelib \masm32\lib\kernel32.lib .data hello db "Hello", 0 szbuffer db 64 dup (0), 0ah .data? writehandle dd ? readhandle dd ? .code start: invoke GetStdHandle, STD_INPUT_HANDLE mov writehandle, eax invoke GetStdHandle, STD_OUTPUT_HANDLE mov readhandle, eax invoke ReadConsole, readhandle, offset szbuffer, sizeof szbuffer, ebx, NULL invoke WriteConsole, writehandle, offset szbuffer, sizeof szbuffer, ebx, NULL invoke MessageBox, NULL, offset szbuffer, offset hello, MB_OK invoke ExitProcess, 0 end start
You can also use the stack to do this:
Code:
push 0 ; empty a spot on the stack invoke WriteConsole, writehandle, offset szbuffer, sizeof szbuffer, esp, NULL pop ebx ; fix the stack & receive the bytes received in ebx
