SYMPTOMS

The showModalDialog() function allows you to pass a value into the dialog window. If the method is called from VBScript and a variable is passed to it, as opposed to a literal value like "hello," accessing the dialogArguments property of the window object from within the HTML page that is displayed with showModalDialog will result in a type mismatch error.

MORE INFORMATION

Steps to Reproduce Behavior

The following VBScript code calls showModalDialog to access the modalDlg.htm Web page and passes a string variable as the second parameter. This VBScript subroutine is called in response to a button on the page being clicked.

   <SCRIPT language="VBScript">

      Sub btn_onClick()
         sArguments = "OK"
         showModalDialog("modalDlg.htm", sArguments)
      End sub
   </SCRIPT>

When you access the window.dialogArguments window property from within Modaldialog.htm, you receive a type mismatch error. Here is the HTML code for Modaldialog.htm. This HTML creates a button that, when clicked, displays dialogArguments in an alert box.

   <HTML>

      <BODY>
         <BUTTON       onclick="alert(dialogArguments)">dialogArguments</BUTTON>
      </BODY>

   </HTML>
