This tip explains step-by-step how to use LotusScript to open an Internet Explorer browser as dialog box to transfer values between a Lotus Notes client and a Web-based application.
- Create a form.
- Go to Form Global Declaration and declare the following:
Dim Uidoc as NotesUidocument Dim IE as variant
- Create an Editable Field Name called "HTML."
- Create a button named "Open," and then copy the following script:
Dim Ws as New NotesUiWorkspace Set Uidoc= Ws.CurrentDocument Set IE=CreateObject("InternetExplorer.Application") IE.Height=450 IE.Width=550 IE.ToolBar=False IE.StatusBar=False IE.Resizable=False IE.Navigate "http://notes.net/46dom.nsf" IE.visible=True - Create a button and name it "Populate":
Dim StrValue as string StrValue=IE.document.getElementByID("content-table").innerHTML IE.Quit call uidoc.FieldSetText("HTML",StrValue) - Compose the form.
- Click on the "Open" button, and you'll find a "dialog box" opening the "notes.net" Web site.
- Go back to Lotus Notes, click on the "Populate" button, and you will see the HTML populated in the Lotus Notes field.

a pause and retry loop in the "OPEN" script to perform the "POPULATE" function. (This could also be used as the code behind the POPULATE button)
'---- append to OPEN script
'Repeat until we give up or have success ..
Const retry_count = 20
Const ElementID = "content-table"
Dim aa%, Success%
Dim StrValue As String
aa = 0
Success = False
On Error Goto KeepTrying
GetElement:
' This fails if the page is not loaded yet
StrValue=IE.document.getElementByID
( ElementID ).innerHTML
' We only get here if we retrieved the element ..
Call uidoc.FieldSetText("HTML",StrValue)
Success = True
Goto TheEnd
TryAgain:
Sleep 1
aa = aa + 1
If (aa<retry_count) And (Not Success)
Then Goto GetElement
TheEnd:
IE.Quit
If Success Then
Print "Success in " & aa & " second(s)"
Else
Beep
Print |Failed: either the URL did not load in |
& retry_count & | seconds or the element "|
& ElementID & |" does not exist in the page.|
End If
Exit Sub
KeepTrying:
Resume TryAgain
'---- end code ---
