Why is HotkeySet() not working with clipboard data? - clipboard

Question

My clipboard controller could have several items copied to the clipboard when using a hotkey (CTRL + SHIFT + Q), instead of only one item, and pastes all at once (CTRL + SHIFT + W), or paste any of the first 10 items directly (CTRL + SHIFT + 1 … 9). Another option is to clear the clipboard (CTRL + SHIFT + -).
It works just for several copy and pastes, but then trying to make a copy operation nothing is added to the buffer. I couldn't find a reason for this.
Code (problem should be in the addToClipboard() or getAll()) :
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <array.au3>
Global $clipBoard[50]=[""]
Global $counter = 0
HotKeySet("^+q","addToClipboard")
HotKeySet("^+-","emptyAll")
HotKeySet("^+w","getAll")
HotKeySet("^+1","get1")
HotKeySet("^+2","get2")
HotKeySet("^+3","get3")
HotKeySet("^+4","get4")
HotKeySet("^+5","get5")
HotKeySet("^+6","get6")
HotKeySet("^+7","get7")
HotKeySet("^+8","get8")
HotKeySet("^+9","get9")
$hGUI = GuiCreate("Clipboard Controller", 100, 100,Default,Default,$WS_SIZEBOX)
GUISetState()
Func addToClipboard()
Send ("^c")
$copied = ClipGet()
$clipBoard[Mod($counter,50)] = $copied
$counter +=1
EndFunc
Func getByIndex($i)
$statement = $clipBoard[$i]
ClipPut($statement)
Send("^v")
EndFunc
Func getAll()
$statement =""
For $i In $clipBoard
If $i <> "" Then
$statement &= $i & #CRLF
EndIf
Next
ClipPut($statement)
Send("^v")
EndFunc
Func emptyAll()
For $i=0 To 49
$clipBoard[$i]=""
Next
ClipPut("")
EndFunc
Func get1()
getByIndex(0)
EndFunc
Func get2()
getByIndex(1)
EndFunc
Func get3()
getByIndex(2)
EndFunc
Func get4()
getByIndex(3)
EndFunc
Func get5()
getByIndex(4)
EndFunc
Func get6()
getByIndex(5)
EndFunc
Func get7()
getByIndex(6)
EndFunc
Func get8()
getByIndex(7)
EndFunc
Func get9()
getByIndex(8)
EndFunc

Problem is an old trap...
It takes a small amount of time to copy to the clip board
especially large items..try a sleep after the Send
Func addToClipboard()
Send ("^c")
sleep(1000) ; try different values
$copied = ClipGet()
$clipBoard[Mod($counter,50)] = $copied
$counter +=1
EndFunc
anyway like your script..idea

The problem is the code for addToClipboard is running while the user still has the keys pressed down. As a result, the Send command designed to send just Ctrl+C is in effect sending Ctrl+Shift+C, so the text is never copied.
The solution is to wait for the user to raise those keys, using the _IsPressed function, then once all keys are released, execute the code. It may also be wise to disable the hotkey when you enter the function (and re-enable when you leave) so that holding the hotkey down for a long time doesn't keep triggering the function.
An alternative would be to send the WM_COPY message directly to the control with focus. This is not guaranteed to work for every control (though I'd be very surprised if it didn't). This would be a far more reliable method.

hope this is the end of the problem , I found another way to set/get data from clipboard , functions : _ClipBoard_SetData () & _ClipBoard_GetData() from library <Clipboard.au3> , after trying them it worked well , after all it seems like the problem was in setting and getting data from the clipboard..
will come later isA to assure whether its finally correct or not
