In the toolbox, right click and select the function for adding new controls.
In the selector window, click on the COM tab.
Scroll to bottom and choose Web Browser.
Drag and drop that to your form or container control.
You may also want to look at the articles on other fun things you can do with that control. (NOTE: I use the word fun with tongue in cheek)
In the main menu get into the C# menu for articles.
Choose the COM Interop selection.
Nick and I have two good articles to read. You are quite likely to need either process or both at some point in time.

Hi,
thanks for your reply. Since I'm not using Visual Studio, I can't simply follow your steps. So I thought, good thing would be to use the tool tlbimp.exe (SDK) to get an assembly from the mshtml.dll typelib, located in the Winnt\System32 folder. But tlbimp keeps telling me, that it is not a valid typelib.
Can you tell me how I can create the appropriate assemblies using tlbimp or aximp so that I can use them eventhough I don't have Visual Studio installed?
Thanks in advance!

I think you should be able to, but you will have a very hard time constructing this without VS!!!

HI!
I am currently at the beginning of a new project and I would like to start
with something out of the box. As we started our Web project we used IBuySpy Portal
and it worked fine because we did not waste our time on authentification,
authorisation and all that but we were able to start right with the logic
of the application. Is there something like that for SmartClient? I mean template
solution containing the newest application blocks of Microsoft?
Any comments or help will be highly appreciated.

As I understand it, the Application Blocks are basically large 'patterns' for deployment. So if you find an Application Block that provides the SmartClient pattern, then that is where you would begin.

I did a windows usercontrol,then I put it in my web appliation.Others client run this web application to http.But, a thing was happened,because I use a localhost's filepath, but,there was not on others client.So,at run time, error was happened. I wanted to know, if web application had windows usercontrol then run my web application on others client, which resource was be used windows usercontrol.

Your question doesn't make ANY sense whatsoever.

You created a Windows Forms User Control? Or did you create a Web User Control?
jzb wrote:

Localhost's FilePath for what? You should NOT be using client FilePaths for anything since, inside a web browser, access to the clients FileSystem is forbidden for security reasons.
jzb wrote:

What? Are you asking what resources a control has access to on the client side? The FileSystem on the client machine is NOT accessible from within a web browser.

Actually, you can embed a Windows Forms UserControl in a web page and it can access the file system (by default in .NET 1.1, using isolated storage), so long as you have the permissions to do so.
See my old article at http://www.devhood.com/Tutorials/tutorial_details.aspx?tutorial_id=388[^].
I think he's having problems access a file on the web server from the UserControl which is executed client-side, but I can't really make any sense of his question either.

I can't really make sense of your question either, but let me try...
You're saying that the UserControl you've embedded in a web page uses http://localhost to access a file on the server? IF so, ALL content in a browser window that users see - including embedded .NET, ActiveX, and Java controls - run all on the client machine. So http://localhost refers to their machine, which requires that a web server be running. While "localhost" resolves to the 127.0.0.1 IP address that all machines define as themselves (the loopback address), putting http:// requires that they have an HTTP daemon (like IIS or Apache) running on the default HTTP port, which is port 80. Fat chance that all your clients have that.
So, remember that your embedded user control runs client-side. The only access back to the server is the same as any user would have to make: you need to use the fully-qualified URL of the server. Any file paths you use must also be local to their machine.
Above all, you must grant your user control permissions by getting the users to install a code group on their machines. If they don't, your options are none to limited so program accordingly. In .NET 1.0, controls in the Internet zone were not allowed to execute at all. In .NET 1.1 (partly thanks to yours truly), controls in the Internet zone are granted some permissions, but not many. The only file system access is through isolated storage (System.IO.IsolatedStorage). So you have to add a code group (do not change the Internet_Zone group!) that grants your assembly/assemblies the necessary permissions based on host or strong name identity evidence (other types of evidence are not collected by IEExec.exe, the managed host for Internet Explorer).
Read my old article, User Controls for Windows and the Web[^], for more details.

Hi
I have a problem with menu and FormBorderStyle = None:
I opened new C# project and set the property FormBorderStyle = None , And added main menu. When I run the application and on the last pixel of the menu, i have got a line drawn. This line divide the menu and the rest of the form. How can I make the line disappear?
Thanks Rafi

Can we define constructor with arguments in web service.
So, suppose the Web service.asmx file looks like:
public class Service2 : System.Web.Services.WebService
{
string b = null;
public Service2()
{
InitializeComponent();
}
public Service2(string b1)
{
b = b1;
}
[WebMethod]
public string HelloWorld(string vivs)
{
return vivs+ b;
}
and at client side, I am creating proxy object like:
WebService1.localhost.Service2 obj = new WebService1.localhost.Service2("Hello");
string myname = obj.HelloWorld("vivekagarwal");
Response.Write(myname);
But the problem is, i am getting error while creating object with passing argument ("Hello").
It is saying that we can't pass the argument.(Even when I have created the default constructor with no-argument)
any body has any idea???..becaz my primary function here is..to initialize the object upon creation...
Thanks

Sure you can define such a constructor, but it won't make a difference. The XML Web Service specifications don't describe activation but remote method calls. ASP.NET - having to instantiate the WebService derivative when calls are made - has to instantiate objects because that's how the .NET Framework works. XML-RPC - a predacessor to XML Web Services and there are now WSDL/SOAP-compliant libraries - simply allows you to call methods with an object at all. For that matter, so does XML Web Services.
Object activation is a feature of the hosting framework - not of XML Web Services.
Even when you instantiate your client proxy for the XML Web Service, the object on the server is not created. It is created on the first call to its methods with a particular lifetime. It's when you make calls that any remote calls are made.
In fact, find yourself a packet analyzer (like the widely popular WinPcap with its corresponding Analyer program) and examine the packets after 1) instantiating the client proxy, and 2) calling a method. You'll actually only see one request (assuming data chunking isn't used for that method): for the method.

Good morning,
I have a custom (windows) user control, which is my own designer host implementation. It all works fine when I run the control in a windows app. I have toolbox, property window, etc.
However, I require this form to be implemented in a web page. I am using the <OBJECT> tag to achieve this, and the control is displayed correctly. It all works as per the windows app, with one small problem!
In my implementation of IContainer.Add, I call
<br />
IDesigner designer = TypeDescriptor.CreateDesigner(component, typeof(IDesigner));<br />
This works fine when hosted in the windows app. In the web however, it returns null. ARGH! If I remove the [Designer] attribute from the control, its ok. I've tried specifying the designer type using typeof and as a fully qualified string. Also tried adding the second parameter (BaseDesignerType) as typeof(IDesigner) and that hasn't helped either??
Apologies for the long post  its driving me mad!!
Anyone have any ideas?
Thanks in advance,
Simon.

When you host a control in IE, the playing field changes. First of all, is the designer in the same assembly as your control, or a separate assembly? What membership condition identities your assembly and what permission set is granted to it based on matching evidence? Are you simply using FullTrust?

Hi,
Thanks for your information.
Yes, the designer is in the same assembly as the control it is designing. This assembly is seperate to the assembly containing the designer host, but as the designer host can 'see' the control, I'm sure it must have access to the designer as well. Both assemblies have full trust (they will only be used on intranet, and security protocols are already in use in other parts of the app, so it's not really a security risk).
I have now resolved this problem. I used Reflector to see what TypeDescriptor.CreateDesigner(IComponent comp, Type designerBaseType) was doing, and copied the code to a local method so I could debug it. If you are interested, the problem appeared to be that Type.GetType(designerBaseType) was returning null. (the designerBaseType parameter was hard-coded to IDesigner).
I got around this problem by changing all the controls (no, users will never add their own controls to this designer!) to use the constructor of the DesignerAttribute that accepts two parameters, and set the second one to the same type as the first. When the component is then added to the design form, I get the DesignerAttribute for that type, and call TypeDescriptor.CreateDesigner with the type specified in the second parameter of the attribute.
OMG  I don't really understand what I just wrote!  - it you are really interested, feel free to email me and I'll try to explain in more detail!!!
Thanks for your reply.
Simon.
PS: Is Reflector the most AMAZING tool for .NET development?!?!

Guys,
I'm connecting to different servers using IP/PORT. So far I'm connected to 70 ip/port at the same time using the statement below. My problem is that if i'm using a port which has a value greater than 70000 it gives me an error "index out of bound"
string stripd = "10.32.54.23";<br />
string strport = "70252";<br />
<br />
IPAddress ip = IPAddress.Parse (stripd);<br />
Int32 iPortNo = Convert.ToInt32 ( strport);<br />
IPEndPoint ipEnd = new IPEndPoint(ip.Address, iPortNo);<br />
socketList[arrcnt].Connect (ipEnd);
I think int32 is not enough for the value=70252 but I tried to change it to int64 but the IEndPoint object doesn't accept long datatype.
Kindly help me, I'm got getting any data for that particular PORT.
Thank you very much in advance

THE TCP/IP specification defines the port as a 16 bit integer. That gives a range of 0 to 65535. You cannot define a port outside that range.

What can I do then I have 5 ports with greater than 70000. Do we have any other object that I can use for this scenario?
Thanks for the help

I don't know how you have any ports greater than 65535 as TCP [The underlying protocol] does not support it. It has nothing to do with the .NET Framework.

Ok. I will check with our administrators why he is sending me these ports. Sorry, I'm new to IP/PORT thing
I thought it's .net problem
