I can't display some controls in the webbrowser such as MultiView, Menu, SiteMapPath or TreeView, is only white screen.
Other controls work. And some controls properties are restricted, I haven't full options. Before I used Visual Studio 2008 and I had less problems than now, I have VS 2010.
I tried to use the WebBrowser control in an ASP .NET application:
public BrowserForm()
{
webBrowser1 = new WebBrowser();
webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
[Code]....
But still it's not working for me as desired...giving me weired errors like:
Error HRESULT E_FAIL has been returned from a call to a COM component
I'm not an expert of threading or COM but trying to convert a WindowApplication to WebApplication which takes a screenshot of a web page provided a URL. :(
How can i generate a thumbnail in asp.net using webbrowser?
We are using website thumbnails/screenshots as an asset like MarketingAssetExchange.
[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:
WebBrowserDocumentCompletedEventHandler
WebBrowserReadyState

I've been using WebBrowser.DrawtoBitmap() in my asp.net page running in separate STA thread to capture web pages as an image. But I found that I'm getting blank images for few sites consistently. I'm aware that the method is not 'officially' supported but it would be nice if someone can provide me any reason or a work around for these blank images issue.
View 3 RepliesIn my windows application I'm loading more than 100 urls in my web browser control one by one in a for loop and need to print them programatically after each URL gets loaded . But, I keep getting the Javascript error for so many URLs. I'm not sure why this error keep coming.
View 2 RepliesYeah some people would say "Are you crazy using winforms controls inside asp forms"... and I think they are right. But I would say.. "I'm not the only one!!, take a look" [URL] So... Doing some kind of stuff like the previous link. I did the following:
using System;
using System.Threading;
using System.Windows.Forms;
namespace XXXX.aspx.Print
{
public partial class Drucker : System.Web.UI.Page
{
private ManualResetEvent mre = new ManualResetEvent(false);
protected void Page_Load(object sender, EventArgs e)
{
Threading();
}
private void Threading()
{
Thread t = new Thread(new ThreadStart(GoAhead));
t.SetApartmentState(ApartmentState.STA);
t.Start();
mre.WaitOne();
t.Abort();

A 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.

View 3 RepliesI have been given a site mainly created with .ASP pages with the majority of the data retrieval done via Functions within tables.
I'm trying to move away from this by implementing GridViews etc however my gridview within any .asp page fails to return any data. I can test the query and it works within the query builder section however the empty template view keeps on appearing.

When i try to create a new model object, the time field gets displayed as "00:00:00" im my model (00 is the initial values) instead of "00:00". Is there something i am doing wrong?
