I am fairly new to hta & vbscript. I have a **hta** script downloaded from internet to delay reboot of computer.
There are button for delay such as 30 min, 45 min, 60 min etc. I would like to use combobox(Dropdown box) instead of button.
I also want my vbscript will work with dropdown box.
Below are the code of hta.
<html>
   <head>
    <title>Reboot Notification</title>
    <hta:application id="oMyApp"
        applicationname="Reboot Notification"
        border="dialog"
        BORDERSTYLE="normal"
        caption="yes"
        scroll="no"
        MAXIMIZEBUTTON="NO"
        MINIMIZEBUTTON="NO"
        showintaskbar="no"
        singleinstance="yes"
        SYSMENU="no"/>
    </head>
    <script language = "VBScript">

EDIT
I can show dropdown box on the hta application but i don't know how to manage vbscript with that.
                        
Basically you should get value from SELECT element. Let's say SELECT element has name btnDelay. To get value of btnDelay you should use btnDelay.Value
Enjoy
