DLL.CallFunction(User32.dll-> ShowCursor)

[goldenix]

So i searched the forum & the google & this code is used everywhere. But If I try to use it it does not work.

Maybe I need to use the _cdecl thing.? Tho I dont know how to do that.

$DllCall = DllCall("user32.dll","int","ShowCursor","int",0) ;hide cursor
ConsoleWrite($DllCall & @CRLF)
ConsoleWrite(@error & @CRLF)

Sleep(2000)

$DllCall = DllCall("user32.dll","int","ShowCursor","int",1) ; show
ConsoleWrite($DllCall & @CRLF)
ConsoleWrite(@error & @CRLF)

This is an example using _WinAPI_ShowCursor().

If you look in the WinAPI.au3 include file, _WinAPI_ShowCursor() uses DllCall("User32.dll", "int", "ShowCursor", "int", $fShow).

There is also a description in the help file, without an example.

;
#include <WinAPI.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

GUICreate("My GUI"); will create a dialog box that when displayed is centered
GUISetState(@SW_SHOW); will display an empty dialog box

$DllCall = _WinAPI_ShowCursor(False)
;$DllCall = DllCall("user32.dll", "int", "ShowCursor", "int", False)

ConsoleWrite($DllCall & @CRLF)
ConsoleWrite(@error & @CRLF)

; Run the GUI until the dialog is closed
While 1
    $msg = GUIGetMsg()

    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
WEnd

$DllCall = DllCall("user32.dll", "int", "ShowCursor", "int", True)
;$DllCall = _WinAPI_ShowCursor(True)

ConsoleWrite($DllCall & @CRLF)
ConsoleWrite(@error & @CRLF)

Maybe goldenix wants to hide the cursor for another application.

To answer this question specifically. What doesn't work?

If you're asking why $DllCall doesn't return a value in your ConsoleWrite, then that's because you didn't use an array for the value (ie... $DllCall[0]).

If you're asking why @error always returns zero, well with the way you have it setup, you're checking the @error of the first ConsoleWrite and not the actual DllCall().

I thought I can hide my cursor universally for all application. I was wrong?

I would like to hide my cursor for Irfanview window. Is it possible to do that? Or notepad window? I tried also like in the second example but my codes do not work.

$Window     = WinGetHandle("[CLASS:IrfanView]")
$Window     = " - IrfanView"oÝ÷ Ù«­¢+Ù=ÁÐ ÅÕ½Ðí]¥¹Q¥Ñ±5Ñ¡5½ÅÕ½Ðì°Ð¤ìÄõÍÑÉаÈõÍÕMÑÈ°ÌõáаÐõÙ¹°´ÄѼ´Ðõ9½Í(ÀÌØí¡]¹$$ô]¥¹Ñ!¹± ÅÕ½Ðím

I cant edit my last post the %#¤/&/¤&% thing again.

The code wont hide my cursor. Simply noting happens.

If you want to hide the mouse cursor from every app then you could do something like

#include <GUIConstantsEx.au3>
  #include <WindowsConstants.au3>
  #include <WinAPI.au3>
  #include <misc.au3>
  HotKeySet("{ESC}","DoQuit")
  GUICreate("My GUI",2,2,0,0,$WS_POPUP); will create a dialog box that when displayed is centered
  GUISetBkColor(0)
  GUISetState(@SW_SHOW); will display an empty dialog box
  mousemove(1,1)
  _mousetrap(0,0,2,2)
  $DllCall = _WinAPI_ShowCursor(False)
;$DllCall = DllCall("user32.dll", "int", "ShowCursor", "int", False)
  
  ConsoleWrite($DllCall & @CRLF)
  ConsoleWrite(@error & @CRLF)
  
; Run the GUI until the dialog is closed
  While 1
      $msg = GUIGetMsg()
  
      If $msg = $GUI_EVENT_CLOSE Then DoQuit()
  
  WEnd
  
  $DllCall = DllCall("user32.dll", "int", "ShowCursor", "int", True)
;$DllCall = _WinAPI_ShowCursor(True)
  
  ConsoleWrite($DllCall & @CRLF)
  ConsoleWrite(@error & @CRLF)
  
  
  Func DoQuit()
      _MouseTrap()
      Exit
  EndFunc

and if you want to stop the mouse from being over a certain window you could do this to make the mouse pass straight through.

;mgrefmousepassthrough
 $lastx = MouseGetPos(0)
  $lasty = MouseGetPos(1)
  While 1
      $np = WinGetPos("Untitled - Notepad");or whatever title you want
      $mp = MouseGetPos()
  
      If $mp[0] >=$np[0] And $mp[0] <= $np[0] + $np[2] And _
              $mp[1] >= $np[1] And $mp[1] <= $np[1] + $np[3] Then
          If $lastx < $np[0] Then
              MouseMove($np[0] + $np[2] + 10, $mp[1],0)
          ElseIf $lastx > $np[0] + $np[2] Then
              MouseMove($np[0] - 10, $mp[1],0)
          ElseIf $lasty < $np[1] Then
              MouseMove($mp[0], $np[1] + $np[3] + 10,0)
          Else
              MouseMove($mp[0], $np[1] - 10,0)
          EndIf
  
      Else
      $lastx = MouseGetPos(0)
      $lasty = MouseGetPos(1)
      EndIf
  WEnd

.....

Seems its my fault for not explaining why i need this. I sort images 500 000 images left to sort. So I need autoit to reduce mouse movement, clicking & key presses.

1) I click once at the image thumbnail & then IrfanView window is opened & I see the image.
2) Mouse cursor is hidden now until I move the mouse in any direction by $range = 20.
3) if mouse was moved by €range > 20 then winclose(IrfanView) & show cursor again.

As you see, I must hide the mouse somehow because its disturbing when I view the image.

That first code only moves my mouse in to the left top corner of my monitor & does not hide the mouse. So it does not do anything.

That second sample, I understand the idea, but in my case it is out of the question, because I will need to move the mouse like a lunatic in the result. I mean this image sorting puts serious stress on my wrist.

So my DLL call was correct? I also tried with True & false & nothing. can it be something is wrong with my Windows?

However this sample hire works & hides the cursor, but only for the GUI created by autoit (Wont hide the cursor for the notepad or Irfan window):

Simply hiding the cursor from view, doesn't necessarily mean that it won't show up with WM_MOUSMOVE on infranviews GUI window. Why not just lock the mouse in place until you are done with the window?

[goldenix]

Why not just lock the mouse in place until you are done with the window?

From my experience I can say, that to close the window by moving the mouse a little is very effective. It speeds up my sorting a lot. other vise I would have to make additional half a million button presses on my keyboard = more time will be spent + more stress on my wrists.
