ReadConsoleOutput() API help

[jassing]

I'm trying to use ReadConsoleOutput() -- I see someone tried, but was unsuccessful. I, too, am ending up with failed results.
I suspect my failure is in not sending the right parameters...
And at this point, I have really pooched my demo to the point I'm not even sure what I was trying to do (with parameters, structure definitions, etc)
I'll try to tidy it up and post my best guess soon...

HI jassing,

Did you found any solution for ReadConsoleOutput?
I'm getting error 87 - wrong parameter whatever i try.

Here is what I have so far:

Code: Select all

cinfo.CONSOLE_SCREEN_BUFFER_INFO
Prototype AttachConsole(dwProcessId.l)
OpenLibrary(0, "Kernel32.dll")
AttachConsole.AttachConsole = GetFunction(0, "AttachConsole")
CloseLibrary(0)

Program = RunProgram("cmd.exe", "/k echo Hello!", "", #PB_Program_Open)
If IsProgram(Program)
  PID.l = ProgramID(Program)
  CloseProgram(Program)  
EndIf

Delay(1000)

If AttachConsole(PID)

  handle = GetStdHandle_(#STD_OUTPUT_HANDLE) 
  If handle
    If GetConsoleScreenBufferInfo_(handle,cinfo)
         
      lWidth.l      = cinfo\srWindow\right  - cinfo\srWindow\left
      lHeight.l     = cinfo\srWindow\bottom - cinfo\srWindow\top
     
      *pBuffer = AllocateMemory(SizeOf(CHAR_INFO) * lWidth * lHeight)
      
      dwBufferSize.coord
      dwBufferSize\x = lWidth
      dwBufferSize\y = lHeight
      
      dwBufferCoord.coord
      dwBufferCoord\x = 0
      dwBufferCoord\y = 0
        
      pRect.SMALL_RECT
      pRect\left    = cinfo\srWindow\left
      pRect\top     = cinfo\srWindow\top
      pRect\right   = cinfo\srWindow\right
      pRect\bottom  = cinfo\srWindow\bottom
    
    
      If ReadConsoleOutput_(handle, *pBuffer, dwBufferSize.coord, dwBufferCoord.coord, pRect.Small_Rect)
        Debug "Success!"
      Else
        Debug "Failed!"
      EndIf
    
    EndIf
  EndIf
  FreeConsole_()
EndIf
