An simple example of how to do an automatic search on google:
Place a WebBrowser control on your form.
Use it's navigate method to load the google page:
MyWebBrowser.Navigate("http://www.google.com");
In order to access the controls on the webpage and use the you need to know what their names are from the html source of the page. If you take a look at google's source you'll see all the controls, and among them these two:
<input maxlength=2048 name=q size=55 title="Google Search" value="">
and
<input name=btnG type=submit value="Google Search">
The first one is the text box where you type the text to search and the second is the search button.
So, all you need to do is fill the text box and after that simulate clicking the "Google Search" button. Like this:
<br />
HtmlElement searchBox = MyWebBrowser.Document.All["q"];<br />
searchBox.InnerText = "code project";<br />
HtmlElement btnSearch = MyWebBrowser.Document.All["btnG"];<br />
btnSearch.InvokeMember("click");
Hope this helps.
Have a nice day!

I forgot to mention. There's a very quick and easy way to find the name of the controls you need from a web page. It's called Firebug. It's a plug-in for Firefox. Just use it.

Hi All,
While parsing an xml document using Xpath navigator how we can check whether a node has child nodes or not. Tried using both HasChildern and IsEmptyChild but no luck.
I should be able to differentiate between
<test>
<node1>No child</node1>
<node2>
<node3> child 1 </node3>
<node4> child 2 </node4>
</node2>
</test>
How to diff between node1 (no children) and node2 (which has children)
Thanks in advance.
Regards

Has child nodes should work fine!
Check your xpath correctly, for best examples with xpath refer w3schools!

Hi,
Thank you for your response. My XML file is
<Countries>
<Country>
<Name> Singapore </Singapore>
<Address>
<State>IA</State>
<PostalCode>20</PostalCOde>
</Address>
</Country>
</Countries>
My Xpath is selecting country element. So how can i differentiate between name element and Address element.
Thanks,
Pani

I have the following line of code:
sqlAdapter.SelectCommand.Parameters.Add(new SqlParameter(strParamName, strParamType, 10));
strParamName and strParamType are strings.
Now, the sig of Parameters.Add is as follows:
Parameters.Add(string, SqlDBType, int);
The value of strParamType is one of the SqlDBType's i.e. "VarChar", "Int", "Bit" etc.
How would I convert the value of strParamType to make it SqlDBType?
Thank you.

Well the first question I would ask is Why are you passing in strParamType as a string, can't you simply pass the SQLDBType instead, they are Enums afetr all. Otherwise you'll have to have a switch statement to select the correct database type from the string passed in.
Always look for the easy option 
Mark.

Thank you for the reply.
I read the parameters from a text file that is why I need to determine the type of the parameter from the string programmatically.

Use the Enum.Parse method to parse the string into an enum value.

Or you could just use Enum.Parse

you all suggested to use enum.parse must be the way to go although i can't try it right now (no compiler).
anyhow, the problem above is similar to the following simplified version:
if( strType == "int" )
{
//instantiate an int i.e.
Add(varInt, int, 10);
}
thanks for the help... hope enum.parse is what i am looking for.

Is it a good idea to have my Data Access Layer on Web Service?
What I mean is, All communication of different tier with the underlying database must all be done using XML web sevices.
What are the Cons and Pros of my idea?
Thanks in Advance.

Start with a class library project, not a Windows, or Console application.
only two letters away from being an asset

I - as a user - am running a daemon that I want to provide some service to other applications that I am running. Some of my applications are also using a library that interfaces with this daemon.
Currently I'm using WCF via named pipes so all the plumbing is taken care of for me, but this solution seems to fall apart whenever another user logs onto the machine and also tries to start this daemon. Is there any way for both of our services to co-exist peacefully?
Specifically, how can I allow multiple users to run a daemon concurrently (limited to one daemon per user) while
- ensuring that a library running under user A's account will try to connect *only* to the daemon also running under user A's account, and
- ensuring that the daemon running under user A's account will allow connections *only* from applications running under user A's account.
I was thinking of creating a uniquely named pipe that derives from the user's SID, but this seems more like a hack than a solution and I think it would be quite fragile. I also wouldn't know how to limit connections to only the current user.
If I'm going about this in the wrong way, that would also be nice to know.
Thanks for any insight you guys and gals are able to provide!

Windows services are per-machine, not per-user. One way to accomplish what you are doing is to have a service that does all of the work and then a client-side piece that communicates to the service. The client piece runs per-user and is what the user would interact with, but it wouldn't be a service. It could be a task-tray application (one that only runs in the system notification area).

Right. I was considering just adding a daemon executable to the Startup path of whichever user installed the application.

Ideally the user could install and run this application without requiring administrator privileges. Also, I want to minimize as much as possible the possibility of cross-communication between clients and daemons running under different user accounts.
In reality what I have going on is that the client is performing all the work. The client just needs to query the daemon for some state before work can commence, and it needs to tell the daemon how to update the state when the work is complete. When the next client queries the state, the daemon can respond with the updated information.
The problem with a system-wide service is that the daemon can be used quite broadly, and the client might update the state with some private information. If the daemon is used as a day planner, for example, the client might add a personal appointment to the database. This isn't information that should be accessible to any other user of the system.
Hopefully this clarified things a bit. Again, thanks for your insight!

Yes, that would be a good approach.

Running the client piece without admin privs should be relatively simple. Installing without them might cause an issue on Vista.

It sounds like the service is really just being used as state management.

I'm not sure why this would be an issue. If the service is designed right and provides some sort of authentication mechanism between itself and it's clients, client A should never be able to see data from client B. Given the scenario you described, the underlying data store would need to be protected as well.

Howdy
I've recently converted from Java to .NET and I'm having problems with exceptions. The process for catching and handling exceptions in C# is identical to Java, no problem there. My problem lies in discovering the possible exceptions thrown by methods.
In Java the method signature explicitly declares whether a method throws a exception (or exceptions). This does not seem the case with C#. When viewing the class MSDN I cannot seem to find documentation about the exceptions a method might throw.
The only information I can get is sometime the intelli sense displays a list of exceptions, but this doesn't seem comprehensive.
Is there documentation about what exceptions are thrown by method or a way to find out possible exceptions thrown.
Thanks heaps for any help.
Cheers

Here is a blog I use from time to time
Brad Abrams blog
try
{
screwed up stuff
}
catch(ArgumentException ex)
{stuff catcher}
catch(PathTooLongException ex)
{more stuff}
catch(Exception ex)
(the catch all stuff)
finally
{This always gets hit}

Thanks for you reply
I have good understanding of how to catch and deal with exceptions. What I'm looking for is what type of exceptions are thrown.
I might not have been clear enough. I'm basically looking for class documentation that explicitly declares what exceptions are thrown - Similar to the Java API.
Cheers
