I have teamviewer software Server + Client source code. Help

Question

Hello there guys.


The server code I have in my hand for this remote software (not RDP), works 100% like team viewer, only on local network.


I can work on a computer, click, do things, no problem, and the other computer can watch !!!


The way it is coded, it will get the host's local IP, use port 1453, and work it's magic.


In the code below, under button_1 (i think this is where I have to change right?)


How do I use ANY ip, instead of the local ip? The current code detects local IP, and uses it.
I want to use a string ip (any ip I want), and any port I want.


Can this be done? Thank You !
Sorry to put whole code, but I been trying for 6 hours, and now I start to break my furniture.

Thank you again guys !

Answer 1

Logic:- 

 

Use HttpFileCollection and System.IO  classes.

 

In the database, the field which saves the image should be of varbinary datatype. 

 

In your Page Load  Event iterate through each HttpPostedFile in the HttpFileCollection class.

Save it temporarily in a folder. Access the save file in a FileStream. Take a byte variable and read the bytes of the declared FileStream into the byte variable. 

 

Send the byte to the database using Data Command Object with the help of Parameters.Add() .Value function. 

 

On successfull saving in database,  delete the file save in the temporary folder.

 

Code Help :-

 

HttpFileCollection  hfc = HttpContext.Current.Request.Files;

if(hfc.Count > 0)

{

   for(int i = 0; i< hfc.count; i++)

      {

          HttpPostedFile hpf = hfc[i];

          string path = HttpContext.Current.Server.MapPath("Path to save the http posted file"); 

         string imageName = hpf.FileName; 

         InsertPic(imageName);

      } 

} 

 

 

private void InsertPic(string imagename)

{

   try

   {

      string path = HttpContext.Current.Server.MapPath("Path where you saved the http posted file");

      FileStream fsImage = new FileStream(path + @imagename, FileMode.Open, FileAccess.Read);

         //a byte array to read the image

         byte[] imgdata = new byte[fsImage.Length];

         fsImage.Read(imgdata, 0, System.Convert.ToInt32(fsImage.Length));

         string qry = "INSERT INTO TableName(imageField)VALUES(@imageField)";

         SqlCommand cmd = new SqlCommand(qry, SqlConnection);

         cmd.Parameters.Add("@imageField", SqlDbType.VarBinary).Value = imgdata;

          SqlConnection.Open();

         cmd.ExecuteNonQuery(); 

         fsImage.Dispose();

         System.IO.File.Delete(HttpContext.Current.Server.MapPath("Path where you saved the http posted file") + imagename);

      }

     catch (Exception ex)

     {

     }

      finally

      {

           SqlConnection.Close();

      } 

}
