Code to set ShortCut Keys in winforms

Introduction:
The shortcut keys are used to make your application user friendly and easy to use. But as you know there are some default short keys prepared by Microsoft Windows and some times you need to override these shortkeys.

Code:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)

        {

            if (keyData == (Keys.Control | Keys.B))  //Key combination

            {

                 // your code here

                return true;    // indicate that you handled this keystroke

            }

            if (keyData == Keys.Control) //Single Key

            {

                txtamount.Focus();

                return true;

            }

            // Call the base class

            return base.ProcessCmdKey(ref msg, keyData);

        }

Code to set default startup page in web.config

Introduction:

When someone opens your website by entering your domain name in the web browser then by default it will show the startup page. If you haven't setup an startup page than it will look for Default.aspx or index.html page in the source files. You can setup your startup page in web.config file.

Code:

  <system.webServer>
    <directoryBrowse enabled="false"/>
    <defaultDocument>
      <files>
        <clear/>
        <add value="Default.aspx"/>
      </files>
    </defaultDocument>
  </system.webServer>

URL mapping in web.config

Introduction :
URL mapping is very useful tool to make your URL look good and meaningful to site user. It will overcome the querystring issue. The user sometimes got confused with the parameters passed in the url in the form of querystring.

Code :
For url mapping you have to pace this code in the web.config file in <system.web></system.web> tag

    <urlMappings enabled="true">
      <add url="~/ComputerCourse" mappedUrl="~/courses.aspx?cid=2"/>
      <add url="~/ComputerHardware" mappedUrl="~/courses.aspx?cid=3"/>
      <add url="~/MobileRepairing" mappedUrl="~/courses.aspx?cid=4"/>
      <add url="~/CuttingTailoring" mappedUrl="~/courses.aspx?cid=5"/>
      <add url="~/Beautician" mappedUrl="~/courses.aspx?cid=6"/>
    </urlMappings>

            op1.Multiselect = false;

            op1.ShowDialog();

            int count = 0;

            string[] FName;

            foreach (string s in op1.FileNames)

            {

                FName = s.Split('\\');

                for (int Line = 0; Line < objdoc.Paragraphs.Count; Line++)

                {

                    string Filedata = objdoc.Paragraphs[Line + 1].Range.Text.Trim();

                    if (Filedata != string.Empty)

                    {

                        //Append word files data to stringbuilder 

                        sb.AppendLine(Filedata);

                    }

                }

                ((_Application)Objword).Quit();

                //assign stringbuilder object to show text in textbox 

                richTextBox1.Text = Convert.ToString(sb);

            }

            // Code to Find Email Ids from the file content.

            MatchCollection mc;

            mc = Regex.Matches(richTextBox1.Text, "([a-zA-Z0-9_\\-\\.]+)@([a-zA-Z0-9_\\-\\.]+)\\.([a-zA-Z]{2,5})");

Upload file to FTP from windows form applications

Overview : Sometimes we need to upload some files to a web server from our desktop application. The file upload task is pretty easy in web applications but in desktop applications it is confusing because in websites we upload the files on the same server where we are working but in desktop applications we are working on a local computer and the server is come where else.

To overcome this issue I have created a function which will do this task for you.

public static void Fileuploader(string localpath, string username, string password)

        {

            var fileName = Path.GetFileName(localpath);

            var request = (FtpWebRequest)WebRequest.Create("ftp://www.example.com/httpdocs/_sft0258/" + fileName);

            request.Method = WebRequestMethods.Ftp.UploadFile;

            request.Credentials = new NetworkCredential(username, password);

            request.UsePassive = true;

            request.UseBinary = true;

            request.KeepAlive = false;

            using (var fileStream = File.OpenRead(localpath))

            {

                using (var requestStream = request.GetRequestStream())

                {

                    fileStream.CopyTo(requestStream);

                    requestStream.Close();

                }

            }

            var response = (FtpWebResponse)request.GetResponse();

            Console.WriteLine("Success: {0}", response.StatusDescription);

            response.Close();

        }

By calling this function with correct parameters the upload file task will be completed smoothly.
