Hi:

Been playing with AutoItX using both javascript and vbscript ... found some differences in results ... perhaps someone can explain ... or point out the error of my ways.

I have this code in the <head> section of my html document ...

<script type="text/vbscript">
Sub vbEP1()
Set oAutoIt = CreateObject("AutoItX3.Control")
Result_vbEP1 = oAutoIt.RegEnumKey("HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Printers",1)
msgbox("Result_vbEP1 = " + Result_vbEP1)
End Sub
</script>

<script type="text/javascript">
function jsEP1() {
oAutoIt = new ActiveXObject("AutoItX3.Control");
Result_jsEP1 = oAutoIt.RegEnumKey("HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Printers",1);
alert("Result_jsEP1 = " + Result_jsEP1)
}
</script>

... the vbscript (vbEP1) correctly returns the value associated with the first printer definition ... the javascript (jsEP1) returns a null (empty ?) value.

This is also true for the 2nd, 3rd and 4th enumerated values.

Any ideas ?

Hi!

With JScript, try :

var Result_jsEP1 = oAutoIt.RegEnumKey("HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control\\Print\\Printers",1);
alert(Result_jsEP1);

Michel:

Thank you for your suggestion ... unfortunately, it did not make a difference ... I am running XP Pro with SP2 and all subsequent updates from MS ... have you been able to get a non-blank (non-empty) response on your computer ? ... and if so, what are your OS details ?

@AutoIt(X) developers:

a) Does AutoItX officially support running from Javascript ? I notice all examples are vbscript only ... although I have managed to replicate the samples using javascript (albeit with some syntax changes).

Is there a bug with values returned from javascript calls or is this something unique to the RegEnumKey method ?

Thank you for your consideration.

I'm not a dev but I think I may be able to answer your questions:

a. AutoItX runs through the COM interface. Any language that supports this can use AutoItX's functions.

b. I dunno, try something else and see if it works:

function jsEP1() {
var oAutoIt = new ActiveXObject("AutoItX3.Control");
if (oAutoIt.WinExists("Untitled -")) {
alert("An untitled window is open")
}else{
alert("An untitled window is not open")

}
}

try this with and without an Untitled notepad window open.

Hi, Gaev!

With this code, in a file TOTO.HTA :

<hta:application
 application navigable="yes"
 windowstate="normal"
 caption="yes"
 singleinstance="yes"
 showintaskbar="yes"
 />
<html>
<body onload="jsEP1();">
Test Printer Redistry
<script type="text/javascript">
function jsEP1(){
var oAutoIt = new ActiveXObject("AutoItX3.Control");
var Result_jsEP1 = oAutoIt.RegEnumKey("HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control\\Print\\Printers",1);
alert(Result_jsEP1);
}
</script>
</body>
</html>

Give me : "Adobe PDF" on a XP-SP2 with Active-X, in IE, authorized.

Michel Claveau:

Thank you for your second suggestion ... it worked for me too ... it was then that I realized that your first suggestion also works ... didn't work initially because I did not catch the part about the double back-slashes in your first suggestion ... ... sorry about that and thank you for your assistance.

Thank you nfwu for your assistance as well.
