WebBrowser control to show Word.doc

In trying to reply to another thread, I came
upon an apparent technique to "embed" a
Word doc on a VB6 form using a WebBrowser
control, as follows

Code:

---

Dim myFile As String
myFile = "c:\myWord.doc"
With WebBrowser1
    .Top = 100
    .Left = 100
    .Height = 5000
    .Width = 12000
    .Visible = True
    .Navigate2 myFile
End With

---

It works great. The doc appears (along with
scroll bars) and has the look and feel of Word.

But, I say "apparent" because before the doc is
loaded, a File Download dialogue box appears
with buttons

• Open
• Save
• Cancel

and a warning regarding potential harm from
files from the Internet.

In a "normal" web browsing situation, this warning
is definitely a good thing.

But here, since a "trusted" file path was specified,
the warning is a "nuisance".

From MSDN regarding Navigate2 Method:

• Description
  Navigates to the resource identified by a Universal Resource Locator (URL)
  or to the file identified by a full path. The Navigate2 method extends the
  Navigate method to support browsing on special folders—such as Desktop
  and My Computer—that are represented by a pointer to an item identifier list
  (PIDL). However, this is not applicable to the Visual Basic programming
  language. For information on this functionality, see the Using the WebBrowser
  Control from C/C++ section.
• Syntax
  object.Navigate2 URL [Flags,] [TargetFrameName,] [PostData,] [Headers]
• Part, Description
  
  • object Required. An object expression that evaluates to an object
    in the Applies To list.
  • URL Required. A string expression that evaluates to the URL of the
    resource to display or the full path to the file location.
  • Flags Optional. A constant or value that specifies whether to add
    the resource to the history list, whether to read from or write to the cache,
    and whether to display the resource in a new window. It can be a
    combination of the following constants or values.
  • Flags .. Constant Value Meaning
    
    • navOpenInNewWindow ... 1 Open the resource or file in a new window.
    • navNoHistory ................. 2 Do not add the resource or file to the history list.
      The new page replaces the current page in the list.
    • navNoReadFromCache ... 4 Do not read from the disk cache for this navigation.
    • navNoWriteToCache ....... 8 Do not write the results of this navigation to the disk cache.

I then tried adding a flag ...

Code:

---

Dim myFile As String
myFile = "c:\myWord.doc"
With WebBrowser1
    .Top = 100
    .Left = 100
    .Height = 5000
    .Width = 12000
    .Visible = True
    .Navigate2 myFile, navNoWriteToCache
End With

---

... but I still get the dialogue box.

Is there a way to convince VB that it is a trusted
source and thereby prevent the dialogue box from
appearing at all?

The only way I see to get rid of the dialog is to uncheck the little always ask box.
In theory you may be able to modify the registery entery for this option before executing the call then change it back afterwards but I have not looked into this to see what it would take.


Maybe this would be of some help

Yeah, I thought of unchecking the little "always ask" box,
but would prefer not to.

I like your registry entry approach much better. I'll check
it out. Thanks

You're welcome,

I did uncheck it, stumbled across that site looking for a way to re-activate it afterwards ;)
