:( Can anyone help me in plotting on a map using latitudes and longitudes. Am doing a project in using GPS. The methods i used doesn't give enough accuracy. Can anyone give suggestions to improve accuracy. sibish

Both my client and server use asynchronous network read and file reads. the procedure is: my client sends a string(latitude and longitude) and the server reads from the network stream. the server uses the latitude and longitude and plots it in a map and send the length of the block first and then the block(2048 byte blocks). in the first round all fine. but when the second round starts that is when the client sends latitude/longitude and when the server sends the length,we get binary and the prog hangs. code for server is [CODE] using System; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data; using System.IO; using System.Net; using System.Net.Sockets; using System.Text; using System.Threading; using System.Data.SqlClient; namespace AsyncServer1 { /// /// Summary description for Form1. /// public class Form1 : System.Windows.Forms.Form { private System.Windows.Forms.Button button1; /// /// Required designer variable. /// /// // Bitmap b1; public Thread t1; private System.ComponentModel.IContainer components; private System.Windows.Forms.Button button3; private System.Data.SqlClient.SqlConnection sqlConnection1; private System.Windows.Forms.Button button2; int bytesRead; //static int zoom=2; //float la,lo,la1,lo1; // Graphics g; //int id; float x1=(float)49,x2=(float)141.1297,y1=(float)46,y2=(float)344.8689; float la,lo,p1=0,p2=0; static string st; float xb1,xb2,yb1,yb2,lab1,lab2,lob1,lob2; float m,c; Graphics g; static int zoom=2; int flag=0; int count=0; int id,id1=-1; Bitmap bmp1,nw1; string latu; int bytesRead1; private System.Windows.Forms.TabControl tabControl1; private System.Windows.Forms.TabPage tabPage2; private System.Windows.Forms.TabPage tabPage3; private System.Windows.Forms.TextBox textBox1; private System.Windows.Forms.Label label1; private System.Windows.Forms.TextBox textBox2; private System.Windows.Forms.Label label2; //byte[] len=new byte[8]; byte[] len=new byte[8]; public Form1() { // // Required for Windows Form Designer support // InitializeComponent(); // // TODO: Add any constructor code after InitializeComponent call // } /// /// Clean up any resources being used. /// protected override void Dispose( bool disposing ) { if( disposing ) {
