External DialogBox Editor for FASM

Now, This program contens a GRID for more control on editing

Code:

; ,-------------------------------------------------.
; | Dibuja la Malla de la Plantilla (Template GRID) |
; '-------------------------------------------------'
proc dibuja_malla_3bits
locals
.x                      dd 0
.y                      dd 0
endl
                        ; Limpia la pantalla    (Clean)
                        invoke  SelectObject,[memdc],[obj_pincel_fondo]
                        invoke  PatBlt,[memdc],0,0,[max_x],[max_y],PATCOPY
                        ; Inicializa contadores (Start counters)
                        mov     [.x],0
                        mov     [.y],0
                        ; Captura el pincel     (Get Pencil)
                        invoke  SelectObject,[memdc],[obj_pincel_malla]

                        ; Dibuja las lineas     (Paint Rows)
.ciclo_lineas:
                        invoke  MoveToEx,[memdc],[.x],0,NULL
                        invoke  LineTo,[memdc],[.x],[max_y]
                        add     [.x],8
                        mov     eax,[max_x]
                        cmp     eax,[.x]
                        ja      .ciclo_lineas

                        ; Dibuja las columnas   (Paint Columns)
.ciclo_columnas:
                        invoke  MoveToEx,[memdc],0,[.y],NULL
                        invoke  LineTo,[memdc],[max_x],[.y]
                        add     [.y],8
                        mov     eax,[max_y]
                        cmp     eax,[.y]
                        ja      .ciclo_columnas


                        ret
endp

for fit to grid the program uses this instruccion:

Code:

                        xor     edx,edx
                        mov     eax,[lParam]
                        mov     dx,ax  ;Cursor X
                        shr     eax,16 ;Cursor Y
                        and     edx,0xfff8
                        and     eax,0xfff8
                        mov     [.cur_x],edx
                        mov     [.cur_y],eax
                        ; Vuelve a pintar la malla (Again paint Grid)
                        call    dibuja_malla_3bits
                        invoke  SelectObject,[memdc],[obj_pincel_cursor]
                        ; Dibuja marcador de cursor
                        invoke  MoveToEx,[memdc],[.cur_x],0,NULL
                        invoke  LineTo,[memdc],[.cur_x],[max_y]
                        invoke  MoveToEx,[memdc],0,[.cur_y],NULL
                        invoke  LineTo,[memdc],[max_x],[.cur_y]
                        invoke  InvalidateRect,[hWnd],0,TRUE
