Creating Dll Manually

Below image is show the steps to create dll file manually from web service files.

Code for Download a file from a folder

string[] filepath = Directory.GetFiles(Server.MapPath("~\\upload files"));
            foreach (string fileName in filepath)
            {
                string filename_read = Path.GetFileNameWithoutExtension(fileName);
                if (hidden_tar_file.Value == filename_read)
                {
                    System.IO.FileInfo file = new System.IO.FileInfo(fileName);
                    if (file.Exists)
                    {
                        Response.Clear();
                        Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
                        Response.AddHeader("Content-Length", file.Length.ToString());
                        Response.ContentType = "application/octet-stream";
                        Response.WriteFile(file.FullName);
                        Response.End();
                    }
                }

coding for connectoin remote desktop using c#

Process process_conectoin = new Process();
string exe = Environment.ExpandEnvironmentVariables(@"%SystemRoot%\system32\mstsc.exe");
if (exe != null)
{
process_conectoin.StartInfo.FileName = exe;
process_conectoin.StartInfo.Arguments = "/v " + "192.168.1.2"; // ip or name of computer to connect
process_conectoin.Start();
}

 This is another way to run Remote desktop using c#.net

Code for sending sms from C# using way2sms api

Before Write a code use the steps given below

1. Add Web References to your page.
In that web references page just type this "http://www.spiritssoft.com/webservice/sendway2sms.asmx" in url optoin and click go

After Added that

2. use the name space Using com.spiritssoft.www

3. create a object for sending a sms
SendWay2Sms Objsms_send = new SendWay2Sms();

4.write the code given below here

Note: If you send to a single number just write the code what given here.If you want to send more than one person use comma(,) to seperate the numbers.


For sending one number:

String Strsms_result=Objsms_send.sendSmsSpiritsSoft("UserName", "Password", "Number", "message");

For sending more than numbers:

String Strsms_result=Objsms_send.sendSmsSpiritsSoft("UserName", "Password", "Number 1,Number 2,Number 3", "message");
