im looking to change the cursor for the whole screen .. not just my GUI window .. thx

[buzz44]

IM A STILL WAITING >>> i can not believe this ... i know people are ignoring .. why. .. all i want is some help and i have made 3 posts with no reply in about 5 days... bumping CONSTANLY ... all i want to do is know if u can change the mose cursor and if so is it dll .. that is all.

[CyberSlug]

I'm not ignoring you, at least. I just don't know the answer. Sorry

This might help, though:

[buzz44]

yeah i know .. but i just get the feeling ... im sure sum1 on here knows the answer

and ty for the link .. i dont really know anything about dll calling but ill give it a shot =)

thx again

[therks]

Well this is what I've got so far.. but I don't understand calling dll's very well. I did manage to get it to return something besides 0, so I think I might be partially succeeding.. maybe?

$cursor = DllCall('user32.dll', 'hwnd', 'LoadCursorFromFile', 'str', 'test.cur')
$set = DllCall('user32.dll', 'hwnd', 'SetCursor', 'hwnd', $cursor[0])
TrayTip('Debuginfo', 'LoadCursor: ' & $cursor[0] & @LF & 'SetCursor: ' & $set[0], 30)

While 1
    Sleep(100)
WEnd

[buzz44]

thanks... really thanks for the help .. i know have a basis to atleast start one .. ty again

LoadCursorFromFile

If the function is successful, the return value is a handle to the new cursor.

If the function fails, the return value is NULL. To get extended error information, call GetLastError. GetLastError may return the following value:

In your litlle debug tooltip thinf Loadcursor returns 0 .. i manages to get the handle of the new cursor lol .. just gotta be more specific where to look

$Dir = "C:\WINDOWS\Cursors\arrow_r.cur"; can pick any cursor from that diretory
$cursor = DllCall('user32.dll', 'hwnd', 'LoadCursorFromFile', 'str', $Dir)
$set = DllCall('user32.dll', 'hwnd', 'SetCursor', 'hwnd', $cursor[0])
TrayTip('Debuginfo', 'LoadCursor: ' & $cursor[0] & @LF & 'SetCursor: ' & $set[0], 30)

While 1
    Sleep(100)
WEnd

Oh, well it worked fine for me because I had a test cursor in the folder I was running the script from. Guess I should have mentioned that.

[buzz44]

so it actually changed the cursor??

[therks]

Err no, sorry. That was a confusing response from me, too vague. I just meant that my LoadCursor didn't return 0 cus the file test.cur actually existed for me. Sorry for the confusion (and for taking 7 hours to clear it up).

I'd really like to see someone who knows what they're doing with DllCall weigh in on this topic though. Changing the mouse cursor would be an interesting thing to do. (Although I have to admit now, I don't know of any programs that change the mouse cursor outside of their own windows, so maybe it's just not possible.)

[buzz44]

its cool.. i posted then i went to bed and have just checked it now lol .. yeah it would be good to change the cursor =( ... i really want to make into the "eyedropper" cursor that comes with paint but that only changes the shape when its over the default label thing. which is wat GUICtrlSetCursor does... but i it it to people able to reach outside by little window and go ANY where on the screen =( ... and yea we should get dome dll pro in here lol

Did anyone ever have an answer to this???

Thanks

I haven't got the answer but there are some mistakes in the answers given so far I think.

The function LoadCursor from file is

====================================

HCURSOR LoadCursorFromFile(

LPCTSTR lpFileName

);

Parameters

lpFileName

[in] Specifies the source of the file data to be used to create the cursor. The data in the file must be in either .CUR or .ANI format.

If the high-order word of lpFileName is nonzero, it is a pointer to a string that is a fully qualified name of a file containing cursor data.

Â

If the high-order word of lpFileName is zero, the low-order word is a system cursor identifier. The function then searches the [cursors]section in the WIN.INI file for the file associated with the name of that system cursor. For a list of cursor identifiers, see Remarks.

========================================================

LPCTSTR is a dword I think not a string.

The cursors in WIN.INI are

++++++++++++++++++++++++++++++++++++++++++++++++++

Value Description

OCR_NORMAL normal arrow cursor

OCR_IBEAM I-beam cursor

OCR_WAIT larger hourglass cursor

OCR_CROSS crosshair cursor

OCR_UP up arrow cursor

OCR_SIZE size cursor

OCR_ICON icon cursor

OCR_SIZENWSE NW to SE sizing cursor

OCR_SIZENESW NE to SW sizing cursor

OCR_SIZEWE horizontal sizing cursor

OCR_SIZENS vertical sizing cursor

OCR_SIZEALL horizontal and vertical sizing cursor

OCR_SIZENO international no symbol cursor

OCR_APPSTARTING smaller hourglass with arrow cursor

The constants for these cursors are:

OCR_NORMAL 32512

OCR_IBEAM 32513

OCR_WAIT 32514

OCR_CROSS 32515

OCR_UP 32516

OCR_SIZE 32640

OCR_ICON 32641

OCR_SIZENWSE 32642

OCR_SIZENESW 32643

OCR_SIZEWE 32644

OCR_SIZENS 32645

OCR_SIZEALL 32646

OCR_ICOCUR 32647

++++++++++++++++++++++++++++++++++++++++++++++++++

The way to call the function might be something like this (not tried it)

1) to set the cursor to one in the WIN.INI file

$ds = DllStructCreate("dword")

$newcursor = 32515;try a cross cursor

bitshift($newcursor,-16);??get the value of the cursor into the leftmost bits which I think are read as the low order word - could be wrong here

;and need to get the high order word to zero so the cursor number is read from WIN.INI

DllStructSetData($ds,1,$newcursor)

DllCall("user32.dll","int","LoadCursorFromFile","dword",$ds)

2) Since my WIN.INI file doesn't have any cursors in it I guess the most useful way is to set a pointer to the file name.

Again I am making this up and haven't tried this

$dt=DllStructCreate("string")

DllStructSetData($dt,1,"c:\windows\cursors\e_cross.cur")

$ps = DllStructGetPtr($dt)

$ds = DllStructCreate("dword")

DllStructSetData($ds,1,$ps)

DllCall("user32.dll""int","LoadCursorFromFile","dword",$ds)

Hope this adds to the confusion.

Yeah, I thought there was something wrong with those but I don't know dllcalls very well.

[ConsultingJoe]

Still nothing?

this should be a main function!

[martin]

Still nothing?

this should be a main function!

I've tried a few things but no answer yet. This is my latest attempt which is what I think should work.

#include <GUIConstants.au3>
$Form1 = GUICreate("Cursor Test", 200, 200, 200, 200)
$BtnC = GUICtrlCreateButton("set cross", 60,100, 75, 30)

GUISetState(@SW_SHOW)


While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $BtnC
            
            $dt=DllStructCreate("string")
            DllStructSetData($dt,1,"d:\windows\cursors\e_cross.cur")   ;location of cursor file on my PC
            $ps = DllStructGetPtr($dt);make a pointer to the string
            $ds = DllStructCreate("dword")
            DllStructSetData($ds,1,$ps);
            $Res = DllCall("user32.dll","int","LoadCursorFromFile","dword",$ds)
;should return a handle to the cursor
;but returns 0
;tried using $ps instead of $ds but $Res is same
            DllCall("user32.dll","int","SetCursor","hwnd",$Res[0]);set the cursor using the handle returned
            

    EndSwitch
WEnd

Can anyone tell me what's wrong?
