  1. Assign return value of your JavaScript function to JavaScript variable.
  2. Use execScript method of WebBrowser.Document.ParentWindow to call your JavaScript code.

  3. Now retrieve value of the variable via WebBrowser.Document.Script.<JavaScript variable name, case-sensitive> in VB6.

    Private Sub cmdJsFunc_Click()
    Dim retVal As String

    Call WebBrowser1.Document.parentWindow.execScript("v = function(){return 3.14;}; tempJsVar=v();")
    retVal = WebBrowser1.Document.Script.tempJsVar

    MsgBox retVal
End Sub

Try:

Set v = WebBrowser1.Document.parentWindow("v = function(){return callOther();};v()")
