helloo guys..okie iam creating acode that can draw different shapes(lines, squar,..etc)thats done then save their info in text file ..(like the start point ,end point,..etc)..thats cool too ; BUTT the problem is its writting the last thing i draw ..(if i draw line then squar ..it writes squar twice):confused: // save the file string str_Line; System.IO.FileStream fs = new System.IO.FileStream("c:\\graphics.txt", System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.Write, System.IO.FileShare.ReadWrite); StreamWriter streamWriter=new StreamWriter(fs); if(drawwhat==1) { for(int j=0;j less than arraylist_points.Count;j++) streamWriter.WriteLine("Line"); start=(Point)arraylist_points[j]; end=(Point)arraylist_points[j+1]; str_Line=start.ToString()+end.ToString(); streamWriter.WriteLine(str_Line); j++; } } else if(drawwhat==2) { for(int j=0;j { streamWriter.WriteLine("squar"); start=(Point)arraylist_points[j]; end=(Point)arraylist_points[j+1]; str_Line=start.ToString()+end.ToString(); streamWriter.WriteLine(str_Line); j++; } } streamWriter.Flush(); streamWriter.Close(); fs.Close(); } //note : i want the program read from text after saving it..iam dealing VS 2003 !

Why are you reincrementing j in your loops? When you do this
for (int j=0; j < arraylist_points.Count; j++) { ... }you don't need to call j++ in the loop. The
forstatement will increment it for you nicely.Deja View - the feeling that you've seen this post before.

He's processing a pair of indexed items each iteration. I suppose a more appropriate loop expression in the for statement is "j += 2" :) Mark
