UPDATED: If you have added the readClipboard() function to your script, update it now. Fixed major bug that caused the clipboard to stay locked on certain occasions.

---

Here's some great functions I made to get the clipboard text and change the clipboard text! They are based off the non-functional code in these requests: Get Text and Set Text. They are fully functional, but BE CAREFUL when you modify them. I haven't had any problems yet.

Be careful when you modify these.
@Segosa - your problem was (1) no unicode and (2) you did it a bit wrong

Clear Text:
No return value.

code:

---

function clearClipboard(){
    if (Interop.Call("User32", "OpenClipboard", 0)){
        Interop.Call("User32", "EmptyClipboard");
        Interop.Call("User32", "CloseClipboard");
    }
}

Get Text:
Do not remove the try/catch statement. Your clipboard may lock up.
This function will return false if there are errors (including the text being too long. I don't know how long it can go.) or if the clipboard is currently in use by another program. Otherwise it will return the text

code:

---

function readClipboard() {
var CF_TEXT = 1;
var CF_OEMTEXT = 7;
var CF_UNICODETEXT = 13;
var toBeReturned = false;

try {
if (Interop.Call("User32", "OpenClipboard", 0)) {
if (Interop.Call("User32", "IsClipboardFormatAvailable", CF_TEXT | CF_OEMTEXT)) {
var hClipboardData = Interop.Call("User32", "GetClipboardData", CF_UNICODETEXT);
var pchData = Interop.Call("Kernel32", "GlobalLock", hClipboardData);
var size = Interop.Call("Kernel32", "GlobalSize", hClipboardData);
var str = Interop.Allocate(size+2);
Interop.Call("Kernel32", "RtlMoveMemory", str, pchData, size);
toBeReturned = str.ReadString(0);
var unlocked = Interop.Call("Kernel32", "GlobalUnlock", hClipboardData);
} else {
Interop.Call("User32", "CloseClipboard");
return false;
}
Interop.Call("User32", "CloseClipboard");
}
} catch(ex) {
Interop.Call("User32", "CloseClipboard");
return false;
}
return toBeReturned;
}

Set Text:
This function has no return value. To use it, type writeClipboard(String);.

code:

---

function writeClipboard(str){
    var size = str.length*2+2;
    var GMEM_MOVEABLE = 0x2;
    var GMEM_SHARE = 0x2000;
    var GMEM_ZEROINIT = 0x40;
    var memtype = GMEM_MOVEABLE | GMEM_SHARE | GMEM_ZEROINIT;
    if (Interop.Call("User32", "OpenClipboard", 0)){
        var heap = Interop.Call("Kernel32", "GlobalAlloc", 0, size);
        var p = Interop.Call("Kernel32", "GlobalLock", heap);
        Interop.Call('Kernel32','RtlMoveMemory',p,str,size);
        Interop.Call("Kernel32", "GlobalUnlock", heap);
        if (Interop.Call("User32", "OpenClipboard", 0)){
            Interop.Call("User32", "EmptyClipboard");
            Interop.Call("User32", "SetClipboardData", 13, heap);
            Interop.Call("User32", "CloseClipboard");
        }
    }
}
