PDF in HTMLViewer

Targets Web
1

I want to show a PDF file on disk in a HTMLViewer:

[code] Dim f As FolderItem = GetFolderItem(“Mac HD:Users:sander:Desktop:1.pdf”)
If f <> Nil And f.Exists Then
App.MyFile = WebFile.Open(f)

HTMLViewer1.URL = App.myFile.URL

End If
[/code]

Doesn’t work. It downloads the PDF but that’s not what I want. Anybody?

2

you need to specify the path format for the GetFolderitem call…
and webfile may need right mime type.

Yes! The mime type did the trick:

App.myFile.MIMEType = “application/pdf”

Thanks!

So what happens exactly ? Your code does not find the file, or it does not display ? If your client is on PC, the PDF will not display in Internet Explorer without an Adobe Reader plugin.

Your WebFile is going out of scope. I think that kills it before it gets a chance to display. Try using a property of the webpage instead of dimming it locally.

Thanks for the reply, I’m using mozilla firefox and I think that it does not find the file:
404: File Not Found

Tim tried to explain to you that when the event in which you dim wfile ends, wfile ceases to exist. Anything you dim in an event has a scope limited to that event.

So the HTMLViewer cannot use a variable that does not exist anymore.

  • Add a property called wfile of type WebFile to the WebPage (right click)
  • Modify the first line of your code as :
wfile = new WebFile

A WebPage property has a scope of that webpage. It is available to all controls in that webpage, and is available as long as the webpage exists.

Thanks for the help, declare as a “WebPage property” solved my problem!
