so MS is shipping Windows 7 without the Internet Explorer in Europe. How will that affect applications that use the webbrowser class? I assume many MS programs rely on that class and hence they wouldn't really deactivate its function unless the user installs IE separately?

When I do this
Public Class cInherits : Inherits Panel
I get this: Base class 'System.Windows.Forms.Panel' specified for class 'MenuButton' cannot be different from the base class 'System.Windows.Forms.UserControl' of one of its other partial types.
How do I inherit?
I have a class library in VB.NET that does a NET-envelope for an USB device driver.There is only one function of that driver that I could not envelope in a traditional class, but I had to put it in a Windows Service as described here:Sharing a class property (field) between applications.The Windows Service works fine, but I have now two projects for my NET-envelope: the one with the class library, the second with the windows service and I do not like the idea to maintain two distinct projects for the same driver.Is it a good practice (or even if possible) to add a windows service class to a normal class library (without creating its own project as described in the vb tutorial)?I know, in any case I should create a separate setup only for the windows service, but in this way I could have together all the classes that envelope my usb device driver in only one project.

I'm trying to create a windows service that loads a website, navigates it, and pulls some information using javascript. This is all very easy to do in a windows forms application, but isn't working in a webservice (apparently because services can't access the registry WinInet Not Supported for Use in Services). Any ideas how to get it to work? Here's my code that outputs nothing:

I have a vb windows application with 2 forms, where form2 is called from form1 using form2.showdialog()
I added a web browser control to form2, and I'm getting the following error at the point where form2 is called:
Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it.
I tried:
1) adding STAThread() to the form_load()
2) I added a module to my application, and created a sub main(), with the STAThread attribute applied to it
3) I marked the sub startup() with STAThread()

View 1 RepliesVB2005. In my application I am required to go to a website, collect info, and then display both the webpage and the info collected. For this I am using the System.Windows.Forms.WebBrowser component and have it working faily well. The only thing now is that in order to get to external websites the company requires us to login to the firewall proxy server. For example when I visit [URL] a login box pops-up for our firewall server [URL] and I sign in with ID 9999 and password "pass". I am trying to programatically do this with the WebBrowser by using the credentails but have not found any relevant examples. Is this possible with the System.Windows.Forms.WebBrowser component?

View 2 RepliesI have a VB.Net Windows Forms application that incorporates the WebBrowser object.I want to place the input focus/cursor in a textbox after successfully loading a PDF document in the WebBrowser via the Navigate method.I tried to set the focus (TextBox1.Focus) in the DocumentCompleted event handler, but that failed.Or, I should say that the focus does not stay in the textbox.It appears that all processing initiated by the Navigate method is not complete even when the DocumentCompleted event is fired.And, as a result, the input focus is being moved from the textbox for some reason.
I now set the input focus in the ProgressChanged event handler when the CurrentProgress and MaximumProgress event agruments both have values of zero.This is successful, but I want to be sure that I can rely on the values of the event arguments.After I use the Navigate method, the ProgressChanged event is fired 4 times with the following CurrentProgress and MaximumProgress event argument values: 0 of 10000, 10000 of 10000, 10000 of 10000 (again), and finally 0 of 0.Can I confidently rely on a ProgressChanged event at the absolute end of a successful WebBrowser navigation that has CurrentProgress and MaximumProgress both set to 0?

View 3 RepliesWe are using a web browser to show a pdf file located in a folder on the network. The code looks like this:
System.Windows.Forms.WebBrowser.Navigate(New Uri("\hostpath ofile.pdf"))
This works fine, but now I have to use a specific user to access this file and I don't know how to include the user name, password and domain in the URI. Is it posible to add user credentials to the URI? Can I use another variant of Navigate method to accomplish this?
I'm developing an VB.NET application which utilizes a webbrowser control. The browser control needs to navigate to a simple page which prompts the user for their user name and password. However, this prompt is not simply a web form, but it is a completely new dialog window. I need a way to automate filling in the username and password in this dialog by using locally stored credentials, so that there is no interruption in the webbrowser control's navigation. The only information that I have been able find so far that might be useful in solving this problem, involves using windows hooks in the user32.dll to intercept and negotiate with these windows at a low level.
