Hello at all

Someone know a way to read the text into the console windows already visible

Have a good day

Posted: **Thu Nov 14, 2019 1:45 pm**

First idea:

emulate ctrl-a ctrl-c
Then it is in clipboard

Very good one CELTIC88
Thanks

Simple one (If it is OK

)

Code: Select all

Import "kernel32.lib"
  AttachConsole( processID )
EndImport

hConsole = FindWindow_("ConsoleWindowClass",0)
GetWindowThreadProcessId_(hConsole,@procID)
AttachConsole(procID)

nBytes.i
sScreen.s
sBuffer.s
SBI.CONSOLE_SCREEN_BUFFER_INFO
hCons = GetStdHandle_(#STD_OUTPUT_HANDLE)

If hCons
  GetConsoleScreenBufferInfo_(hCons, @SBI)
  dwSizeX = PeekW(@SBI\dwSize)
  dwSizeY = PeekW(@SBI\dwSize + 2)
  For line = 0 To 500
    sBuffer = Space(dwSizeX)
    If ReadConsoleOutputCharacter_(hCons, @sBuffer, Len(sBuffer), Line*$10000, @nBytes)
      Debug Left(sBuffer, nBytes)
    EndIf
  Next
EndIf

Sh..

I tried it already yesterday with nearly the same code like Rashad, but it failed.
I used

Code: Select all

ReadConsoleOutputCharacter_(hStdOut, *Buffer, ConsoleScreenBufferInfo\srWindow\right, ReadCoord, @nBytes)

instead of

Code: Select all

ReadConsoleOutputCharacter_(hStdOut, *Buffer, ConsoleScreenBufferInfo\srWindow\right, PeekL(@ReadCoord), @nBytes)

And I still don't know why it fails.
Here is my 'working' version, with the fix like Rashad did it.

Code: Select all

EnableExplicit

#OnlyVisible = #True

Import "kernel32.lib"
  AttachConsole(processID.l)
EndImport


Define hConsole.i, processID.i, hStdOut.i, NumberOfChars.l, Y.i
Define ConsoleScreenBufferInfo.CONSOLE_SCREEN_BUFFER_INFO
Define *Buffer
Define ReadCoord.COORD
Define X$

hConsole = FindWindow_("ConsoleWindowClass", #Null)
If hConsole
  GetWindowThreadProcessId_(hConsole, @processID)
  If AttachConsole(processID)
    hStdOut = GetStdHandle_(#STD_OUTPUT_HANDLE)
    If hStdOut
      If GetConsoleScreenBufferInfo_(hStdOut, @ConsoleScreenBufferInfo)
        
        *Buffer = AllocateMemory((ConsoleScreenBufferInfo\srWindow\right + 1) * SizeOf(Character), #PB_Memory_NoClear)
        If *Buffer
          ReadCoord\x = 0
          
          X$ = "    "
          For Y = 0 To ConsoleScreenBufferInfo\srWindow\right
            X$ + Right(Str(Y), 1)
          Next Y
          Debug X$
          
        CompilerIf #OnlyVisible              
          For Y = ConsoleScreenBufferInfo\srWindow\top To ConsoleScreenBufferInfo\srWindow\bottom
        CompilerElse
          For Y = 0 To ConsoleScreenBufferInfo\srWindow\bottom
        CompilerEndIf
            ReadCoord\y = Y
            If ReadConsoleOutputCharacter_(hStdOut, *Buffer, ConsoleScreenBufferInfo\srWindow\right + 1, PeekL(@ReadCoord), @NumberOfChars)
              Debug RSet(Str(Y), 3) + " " + PeekS(*Buffer, NumberOfChars)
            EndIf
          Next Y
          
          FreeMemory(*Buffer)
        EndIf
      EndIf
    EndIf
    FreeConsole_()
  EndIf
EndIf

Hi Bernd
Sometime I am lucky with PB

You need the coordinates of first cell to read from
MakeLong(x,y)

I prefer your using of ReadConsoleOutputCharacter_()

Code: Select all

ReadConsoleOutputCharacter_(hStdOut, *Buffer, ConsoleScreenBufferInfo\srWindow\right, ReadCoord\y << 16 | ReadCoord\x, @nBytes)

Posted: **Fri Nov 15, 2019 12:47 pm**

Something wrong with your last update Bernd (1 st. Line)
Go back

Posted: **Fri Nov 15, 2019 3:24 pm**

The first line

0123456789012345678901234567890123456789

is generated 'by hand', only to show the coordinates.

Code: Select all

          X$ = "    "
          For Y = 0 To ConsoleScreenBufferInfo\srWindow\right
            X$ + Right(Str(Y), 1)
          Next Y
          Debug X$

I try with W10 x64 / v5.70 x86

Waaaaooouuhh !!!! all my friends in the same thread

Thanks a lot for all your splendids and powerfull code

it's christmas before christmas

About christmas snow

Excuse me for the late answer, but in my department of France there are so much snow than all cables are fall and i have no electricity, no phone and the emetor not works too so no GSM since three days ago.
All my house is under battery 12V, in fact like if i'm into a motorhome

And today, always not electricity, but just one gsm works...so my first reflex..is come see all my friends in own love PB forum

So i have tested all your jewel codes:

The CELTIC code works fine
The little code of RASHAD too
The first INFRATEC code works here
The last INFRATEC code works perfectly and furthermore with line number

I LOVE YOU ALL

Have the very good day of the world !!!!
