Hey did u try the above programmes with a language u know ........if u r also using java then make some improvements on the code and post here !!! Ill post more problems later !!!!!!!

I'll give a try

Hey Guys check out this code !!!! get two points and return the line !! checked for all occurrences !!!! Please tell me if there are any errors !!!!!!

package line;

     void getLine(Points p1,Points p2){
         System.out.println("Your two points are ");
         System.out.println("("+p1.xCordinate+","+p1.yCordinate+")");
         System.out.println("("+p2.xCordinate+","+p2.yCordinate+")");

         if (yCoeff==0){
             System.out.println("X="+p2.xCordinate);
         }
         else if (xCoeff==0)
             System.out.println("Y="+p2.yCordinate);

         System.out.println("Y="+xCoeff/yCoeff+"X" + op + (constant)/yCoeff);
     }
         else

     }
     }

         this.getLine(this.p1,this.p2);
     }


     public static void main(String[] args) {
         do {

         Line l1=new Line();
         l1.getPoints();
         
         System.out.println("Do you want to Continuw with anothe line:(y/n)");
         char state=input.next().charAt(0);
         if (state=='n')
             isContinue=false;

         } while (isContinue=true);

    }
}

class Points {
      int xCordinate;
      int yCordinate;

Hmm Machan did u have JAVA installed in your PC ....then i suggest you to run this and see!!!!!

Actually this is a simple code for get two points as input and to output the line which goes across that two points !!!!!

Try and see !!!!

I'm currently developing(nearly done ) a C++ program that draws lines on DOS Console Crazy idea huh! it does draw correctly now but i thought of optimizing it a bit, I'll post it tomorrow

Try to code it! and hey give some screenshots(I dont know how to run java codes, just tried running the code lakmal gave for line equation but it gave some errors :S)

Elaz Go on with ur code !!

Actually I run java programmes through Netbeans !!!! but if u haven't installed it on ur PC its all right u can still run this on Command Prompt.

Step 1

Copy the above code to a note pad file and save it on desktop(or a place where u like ) But you have to give the correct path when you Compile the code !!! I think U have installed JDK on ur PC and u have to set path ( i think u know how to do that ) and type javac on command prompt .If CMD identifies the comamnd then u have insatlled jdk succesfully .

Improtantly delete the line "package line;" from ur code ( It is used in Netbeans)

then go to command prompt and go the palce where u saved file (i saved it in desktop) and type javac Line.java

then it will compile and in the next line type java Line

You r done!!!!!!!!!

Can any one help me to create a download manager using VB.net.I want options like download direct links Giving from a text.also need some codes for disconnect a dial up connection.If the link redirect to mirror it also can be download .Plz help.

 

[v7soft]

i dnt knw C++ or java this is C
/*sum of the 1-n odd’s using for loop */
#include<stdio.h>
#include<conio.h>
void main()
{
int i=1, tot=0,test;
printf(“enter the number \n”);
scanf(“%d”,&num);

for (i=1;i<=num;i++)
{
test=i%2;
if(test!=0)
{
tot+=i;
printf(“odd number is%d \n”,i);

}
}
printf(“TOT OF 1 to %d odd’s is %d \n”,num,tot);
getch();
}

I dont know VB.NET but you can use pscode.com
for examples if you want. I recommend API calls to wininet.dll to get things done.
