Web Forms :: Converting C# To Vb.net Form With Webbrowser?
Mar 28, 2011 [Code]....
I found a C# web application that fetchs a thumbnail image of a webpage. It works well, only my site is in vb.net. I used a conversion tool. Windows FORMs doesn't fly, and I get an error. Is there something I can import to get the Webbrowser() to work in my application ? Dim m_Webbrowser as NEW Webrowser is underlined in blue. Also, I have noticed that when I select Show All in my toolobox, alot of tools are greyed out. Specifically under common tools, the webbrowser control is greyed out for a web application but they are available for a project. I want to have a webbrowser control in my website application. (vb.net)Most of the following is also underlined in blue:

Web Forms :: System.Windows.Forms.WebBrowser In Web Form?
Mar 17, 2011A requirement of a program I am making is that it can 'print' a given URL into a PDF - the server has a PDF printer installed (and is the default printer), so it's just a matter of printing the page programmaticly, and it seems the best way is to use the WebBrowser control - however, I am running into issues
[Code]....
With the above code, I get a script error 'dialogArguments.___IE_PrintType' is null or not an object' in shdoclc.dll/preview.dlg. If I have wb.Print() to somethign like wb.ShowSaveDialog() (or something like that, can't remember exactly), I notice the 'wb' object's document is a blank page, with just <html> tags and named 'about:blank'. But strangely, almost identical code (without the threading bit in the page_load method) works perfect in a normal Winforms based application.

Mar 4, 2011I have an Image control on my page that should display a thumbnail preview of the actual image. The URL property of this control is assigned through the code-behind using:
imgHolder.URL = @table.Row[0].ItemArray[0].ToString();
Before moving my files to another location, this assignment works fine (The files used to be located inside the application folder). But after moving all files to another drive in the same server, the images don't seem to render any longer. I can upload/download files fine but they just won't display as thumbnails on the page.
