System.Windows.Forms.WebBrowser Inside WebForm DocumentCompleted Not Fired
Oct 1, 2010
Yeah 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();
}...................................

Now. the DocumentCompleted event is not fired (neither ProgressChanged) and I've tried the next: Add the library MsHtml.dll to my project and place the file into my lib folder... I did it... No changes.Try to handle the state of the WebBrowser.ReadyState... I did it... No changes (Actually after receive the ebBrowserReadyState.Complete I tried to print the document with
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.
If I develop a Windows User Control and host it inside an aspx web form, does the user's machine accessing the aspx page needs .NET Framework?
Does the Windows User Control hosted inside an aspx or web form requires any downloading of the control similar to an ActiveX control? Or Is it rendered like a HTML page?
I want to authenticate to linkedIn website and scrape the content in asp.net. In windows application we use windows brwoser control. Is there any anlternate in web application ?
I have a ASP.NET application. From that, User register, User will get email after registration. My Req : When user click on link provided in email. Then it should go to my ASP.Net application page .

I am sending you the code. It Has two PArts First is CLIENT SECTION and Anpother is STATION Section
1) CLIENT SECTION : It has a dropdownlist binded to SQLDataSource and with this it has an imagebutton bAddClient
bAddClient will open the ModalPopup which will ask user to Add new client. And After Adding the New client when User
will close the ModalPopup MY DropDownList is not getting Populated with the New Client. I have Used UpdatePanels Also
2) STATION SECTION : It has a DropDownList, an Image BUtton , And Grid View. In Grid View it shows station details
On particular client selcted above.
I have given the delete station command on deleting the station that particular entry doesnot goes away.
It Should not be visible after it get deleted
Now when i click on imagebutton a modalpopup will open.
Now In modalpopup i have given dropdownlist , image button(to add new station), Some station Info and save button
Now when i click on dropdownlist it used to close the modalpopup then i seet the autopostback = false. Then it works fine. Is it correct way?
Now when i click on imagebutton it asks user to add new station with a textbox , save station button. When users click on savestation button then it adds station to the DB and it should update the dropDownList of ModalPoup without closing it.
But when I am clicking on imagebutton it is closing the modalpoup.
And When user clicks on ModalPoup SSave Button in end it should update GridView of STATAION SECTION too.

Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.
How can I show message box after moving my website to IIS?
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:

I have a treeview named Treeview1 with checkboxes. I want the child checkboxes to be checked if parent is checked.
I am trying to use a simple code that I found on msdn :
[Code]....
For some reasons I got this error and I really dont understand why:
Type 'System.Windows.Forms.TreeViewEventArgs' is not defined.
warning BC40056: Namespace or type specified in the Imports 'System.Windows.Forms' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.
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. :(
I want to create a small helpdesk ticket control system at work, that would allow users to enter a help request ticket; these tickets would then be assigned to a technician to work on, and the technician would mark it as "FINISHED" after the job is done. The requesting user would then be able to confirm and "CLOSE" the ticket, so that a Help Desk supervisor can keep track of response times and other stats based on the ticket details. Nothing too complicated, using .NET and SQL Server.
I am not sure if I should develop this as a Web application or a Windows application. This application would be used in the plant floor, so it would have to be easily available in the LAN. But we currently host a list of Windows applications via Citrix, so deployment would not really be an issue here. I don't really have experience creating winapps from scratch (though I've modified quite a few), but it feels like a web application would not look as "solid". What advice can readers provide that could guide me into deciding the better architecture for this purpose?
