The problem with the correct operation of ClipGet()

[HurleyShanabarger]

I am able to reprocude the behaviour of the first script when running the second script. I don't believe it is an error in the language or the function. If you accessing the clipboard mulitple times the access to it get sometime rejected.

That is why you should stick to a good coding pratice and include fail-safes:

Dim $sClip_Act, $sClip_Old
ClipPut("12345")

While 1
    Sleep(5)
    $sClip_Act = ClipGet()
    If @error Then
        ConsoleWrite("Error:" & @tab & @error & @CRLF)
        ContinueLoop
    EndIf

    If $sClip_Act <> $sClip_Old And $sClip_Act Then
        $sClip_Old = $sClip_Act
        Beep(800, 100)
        ConsoleWrite($sClip_Act & @CRLF)
    ElseIf Not $sClip_Act Then
        Beep(800, 100)
        ConsoleWrite("Empty" & @CRLF)
    EndIf
WEnd

Run this code and start your second script: you will get "Error:   3" all the time.

Thank you very much for your participation, HurleyShanabarger!
Yes, of course, constantly flies out:  Error: 3  

So what's the problem? Why prevents the second script from getting the value of the buffer to the first script? After all, the value of the buffer does not change either the first or the second script. They just read the value of the buffer.

It turns out that simultaneously two scripts can not extract information from the buffer with the function ClipGet(). It is necessary to check constantly an error(if it is 3) and again to launch ClipGet(). Correctly I understood?

I explained the problem already.

If two programs try access the clipboard at the same time, one operation will fail - this not related to AutoIt. Run your second script and open excel, write something into a cell and try to copy it. Most likely you will get an error like this:

In my Excel, the paste works without problems, but sometimes when copying, the following error occurs: "the error of clearing the clipboard" and "error opening the clipboard."
Once Excel even flew completely. )))

Thank you, HurleyShanabarger, for your time and help!

Now it is clear that you will need to track all of your scripts when using ClipGet () error 3/4. I could not assume that you can not read the information from the clipboard at the same time!
