The match to do that is quite simple:(?:\d|\s)(?<data>html)(?:\d|\s)

Find (but do not capture) either a digit or a whitespace,
Find and capture in a group called data the four characters 'h', 't', 'm', 'l' in that order,
Find (but do not capture) either a digit or a whitespace.

But I doubt that will solve your problem!

What are you trying to achieve? It looks as if you are trying to process a CV and extract all the relevant job skills without manually looking at it. If so, then you may need to be a bit more clever / thorough about it, particularly with a trigger word such as "html" which appears in every web page...

Yes You are absolutly right. I did that with the help of a javascript.

Thanks

Just to add to what I said, go and get a copy of Expresso - it examines and generates Regular expressions.
Expresso[^] It's free, and really can help create and understand complicated expressions. You can also feed it a sample file that you want to examine and it will show you what the Regex will capture.
I wish I'd written it!

Thanks but I already have one Smile | :)

,

my query is solved now I got the solution by using

(?<=\\d+(\\.\\d*)?|\\b)html(?=\\d+(\\.\\d*)?|\\b)

but I am having a new query now?
(?:.....) is also a non capturing group so I can theoretically use it in place of look ahead and look behind but that does not work here?

any solutions?

Thanks

Trying to Shut Down application

First of all, I know this question is only partially relevant to C#, so sorry for posting it here.

I am trying to implement Facebook single sign on using a desktop application. The one thing I figured out so far is to retrieve an access token.
How I retrieve the access token:

browserFacebook.Navigate(@"https://graph.facebook.com/oauth/authorize?client_id="+ FacebookApplicationID + "&redirect_uri=http://www.facebook.com/connect/login_success.html&type=user_agent&display=popup");

This redirects the user to page where he/she must first authorize the application. Once authorized, I redirect the user to "http://www.facebook.com/connect/login_success.html" as specified in the above address. I then intercept this URL to retrieve the access token like so:

string someString = browserFacebook.Url.ToString();

This returns something like the following:

"http://www.facebook.com/connect/login_success.html#access_token=ACCESS TOKEN.expires_in=0"

I can then easily use this access token with the Graph API to access an users facebook details as in the following code:

Facebook.FacebookGraphAPI g = new FacebookGraphAPI("ACCESS_TOKEN");
var fbUser = g.GetObject("me", null);

Can I also use this token somehow to simply log a user in to the site? My goal is not really to develop a complete new facebook application as my application is simply a prototype.

Good Morning,

I feel like Dr Frankenstein; I created this monster and now I cannot shut it off! Case in point. My application begins with a Splash screen that retrieves information (Connections Strings, Permissions) and sets a switch in a remote database that defines the users status as active. I hide this page when I advance to the next page (The Main Page). Now, I try to shut it down. I call a method from the Form_Closing event so that I can reset the users status as inactive and I use Application.Exit() as the closing command. BUT....my back trace shows that the script re runs the Splash page and turns the switch in the remote database back to active again before it closes. NOW.... when the user goes to log back on again, the system denies him access with the response that he is already active. In essence, the function of the code is to discourage a hacked application from being able to open if the original application is already active. It's a just in case scenario. SO...what to do? Thanks, Pat

private void frmMain_FormClosing(object sender, FormClosingEventArgs e)<br />
        {<br />
            if (alreadyClosing)<br />
                {<br />
                    return;<br />
                }<br />
<br />
            //If there are results posted<br />
            if (richTextResult.Text != string.Empty)<br />
            {<br />
                DialogResult answer;<br />
                string message1 = "Are you sure you want to exit the program? " +<br />
                    "\n\nThe information in your Result box will be lost!";<br />
                answer = MessageBox.Show(message1, "Exit?", MessageBoxButtons.YesNo, MessageBoxIcon.Question);<br />
                if (answer == DialogResult.No)<br />
                {<br />
                    e.Cancel = true;                    <br />
                    return;<br />
                }<br />
                else<br />
                {<br />
                    ResetDatabaseActivity();<br />
                    alreadyClosing = true;<br />
                    Application.Exit();<br />
                }<br />
            }<br />

Hello Stark,

Thank you for your reply. No, unfortunately, the alreadyClosing bool is required. When the application closes, if it is not in place, it trys to run this code twice. This switch is just a stop measure. It's not a big issue, but it takes 2 clicks to close the question box. That is the only reason that it is there. However, I just realized that Application.Exit() call is not required at all, since it is already staring to close before the call. Sometimes (Pat) cannot see the forest through the trees. I removed it and the problem has been solved. Thank you for your thoughts and input. I appreciate it. Best Regards, Pat

You need to add it as a reference. By default, it doesn't get added to console applications. Why would it? They aren't responsible for drawing windows after all.

In your solution explorer, right-click References (looks like a folder), Add Reference. Then find the one you need.

I will advise you that using keyloggers maliciously (such as to spy on someone, steal passwords etc) is ill-advised, and probably illegal.

A console application does not include Windows by default. You need to add it to the References section of your project in order to use it. However, if you are developing an application that needs Windows why would you start with a console app?

Well, I wonder how you expect to write a working application if you do not understand the basics.

However

Use your mouse to right-click on the References item in Solution Explorer.
Select the .NET tab in the popup dialog.
Scroll down to System.Windows.Forms, and select it.
Click on OK.
Add the using statement to your source module.

Oh, it doesn't; I make too many mistakes to worry about criticism. I would just prefer to have an explanation of what I did wrong.
