How to log to console when using IEFrame.dll

212 Views Asked by Jeff At 13 April 2025 at 02:45

I'm working on a legacy application that is written in VB6 and uses the IEFrame.dll. There is some JavaScript that is not running consistently and I'd like to write some logs somewhere to help figure out what is going on. Is this even possible with IEFrame.dll?

It might make some people cringe, but consider the following:

sample.htm

<html xmlns:custom>
    <body>
        <custom:generic id="Logging" style="inline:true;display:none"/>

        <button onclick="Logging.innerText='Hello';Logging.click()">Click me 1</button>
        &nbsp;
        <button onclick="Logging.innerText='Goodbye';Logging.click()">Click me 2</button>
    </body>
</html>

Form1.frm

Option Explicit

'Reference to: Microsoft HTML Object Library

Private WithEvents Logging As MSHTML.HTMLGenericElement

Private Sub Form_Load()
    WebBrowser1.Navigate2 App.Path & "\sample.htm"
End Sub

Private Sub Form_Resize()
    If WindowState <> vbMinimized Then
        WebBrowser1.Move 0, 0, ScaleWidth, ScaleHeight
    End If
End Sub

Private Function Logging_onclick() As Boolean
    Debug.Print Logging.innerText
End Function

Private Sub WebBrowser1_DocumentComplete(ByVal pDisp As Object, URL As Variant)
    Set Logging = pDisp.Document.All("Logging")
End Sub
