if i write "Point p = Cursor.Position",the p is the location of the control or the form who contain the control.

Cursor.Position or Control.MousePosition

both give screen position

convert back to position inside myControl using myControl.PointToClient()

You do realize there is a thing called documentation ? see MSDN either inside
Visual Studio or on the web.

Look into the GetCursorPos API command of Windows. Do a quick search on MSDN.

Getting installed browser user agents in a Windows Forms program

I have a Windows Forms program, written in C#. Not a ASP.NET web page. And I'd like to get the value of the Firefox and Internet Explorer user agents, if this is at all possible. Any ideas?

Have you tried the link below:

The first hit should solve your problem.

I indeed saw that page and others like it. The problem is that the registry only stores those values if the user has changed his/her user agent. If the user has left it as default, then it's unknown what the user agent is, as those keys don't exist.

I guess I could have fun reconstructing the user agent string from the user's platform, browser version (which shouldn't be too hard to find), and then those add-on strings which I think are stored in the registry (.NET CLR etc.)

Asychronous call to URL behind the scene without redirecting to the page

Hello There,

I have technical problem in with web project.

I'm trying to pass form data (hidden fields) to a url without redirecting to the page.

In other words, lets suppose my web project has 2 files 1.aspx and 2.aspx.

A user submits a form on 1.aspx and the page navigates to 2.aspx. But before navigating to 2.aspx I'm validating the user inputted data. After the validation I need pass the status of validation(Valid or Invalid data) to an external url lets suppose http://somewebsite.com/3.aspx.

The posting of data to http://somewebsite.com/3.aspx has to happen asyncronously behind the scene so that user navigates from 1.aspx to 2.aspx.

Could anyone please help me...any reference to any articles will be of great help.

Thanks!
Amit.

There's a deployment Wizard in Visual Studio, so have a look at that. There's also ClickOnce deployment as an alternative.

I've recently finished a c# book(I had a background with c++, but never made anything 'real' myself)

Currently I have an idea for a little program but I need it to be able to automatically open a website, write something in its search engine and download the first result.
Whilst concept wise I think I know how I can open a website(using some BCL).
Also, I know how to make it 'search' for it only by giving a url + the keyword of the search integrated there, is there a better way?

and the most important question, how can I get it to automatically download it? (using a software I make the user specify)

hey

I have a property:

int MyProperty{<br />
get{return myProperty;}<br />
}

When we ran FXCop it threw up:
Info : "Do not use names that require case sensitivity for
uniqueness. Components must be fully usable from both
case-sensitive and case-insensitive languages. Since
case-insensitive languages cannot distinguish between
two names within the same context that differ only
by case, components must avoid this situation."

So what should I rename myProperty?

cheers

Hi,

I do this all the time, but only in specific situations; i.e.
the local variable is declared private, and the property is either
protected or public.

And I do not intend on changing that. How else would you come up with
two different but related names (don't give me the underscore stuff,
such as _myProperty or m_myProperty, I don't like it at all, it lowers
the readability of the code).

Did you add those different qualifiers when trying?
If myProperty and MyProperty both were to have the same access rights
(which is private if you dont specify), then I would agree with FxCop.

I dont know, and I would be surprised if any of the major ones
would be case-insensitve. I read all languages but on CLR I only speak C#

I do know a lot of "cross-linkers" (I am an embedded guy actually) are either
case-insensitive or have a switch to let the user choose.

Visual Basic, Eiffel for starters.

However, FxCop should really only be objecting about public identifiers that differ only by case. It shouldn't really object to the original example and I would disable that rule.

Just my opinion, but I rather like the m_propertyName way of doing it. With a quick glance in a function you can tell whether or not the code is operating on a member or a local, and also groups them all together in Intellisense so you can easily search through your member variables.

Hi Phil,

That is absolutely true, but it does not change the fact
I don't like how it looks.

Some people still prefix a polish-style type indicator to every
variable, as in string strMyName;

I prefer identifiers to be strictly functional;

I do prefix interface names with "I" since that is a hard convention;

and I tend to prefix Controls with their type ("frm", "pan", "btn", ...)
mainly to be able to do things such as bool caseSensitive=cbCaseSensitive.Checked;

but that is all.

I do understand large organizations should impose strict rules,
and the larger the project the more it may benefit from them,
and from having some prefixes such as the m_ for members.
