Read from text file
-
heloo guys.. u really doing agreat job ..any way i have created strings for each shape (lines,polygons,..) each string contains informations about the shape( x1,y1,x2,y2,R,G,B,pen width) ..Now how can i make my prog read from the text and draw the shapes ..as example the line string : public void AddSv(Line l , ref string str) { if(drawwhat==1)// as one means lines str +="1"+"\n"+l.First.X.ToString()+"\n"+ l.First.Y.ToString()+"\n"+ l.Second.X.ToString()+"\n"+ l.Second.Y.ToString()+"\n"+ l.Pen.Color.R.ToString()+"\n"+ l.Pen.Color.G.ToString()+"\n"+ l.Pen.Color.B.ToString()+"\n"+ l.Pen.Width.ToString()+"\n\n"; after i draw the line i click on save to send the informations to the text : private void button1_Click(object sender, System.EventArgs e) { //save 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); streamWriter.WriteLine(LineSv); streamWriter.Flush(); streamWriter.Close(); fs.Close(); }as u can see i dealing vs 2003 . Regards;;)

you need to read the string, then you need to parse it. It would make more sense to put commas between data items, so each shape is a line of text. They read the file as a string[] and call string.Split on each line to turn 1,2,34,5, into an array of strings, which you can then turn into numbers with int.TryParse. You can read the first number and use it to decide which function to send the array to, so that it can be parsed and objects added back to your array. It would make more sense for the Line,Square,Triangle,Circle,whatever classes to offer a method that returns the string, so you can just iterate over your collection of base objects and call it.

I may have hit myself in the head, but didn't we have an XmlSerializer class laying around somewhere? :-D

do u mean like that : if(openFileDialog1.ShowDialog()==DialogResult.OK) { StreamReader streamReader=new StreamReader(openFileDialog1.FileName); string m=streamReader.ReadToEnd(); string []x= m.Split(); MessageBox.Show(m); streamReader.Close(); } but this displays all the data in the file even after putting commas between data like 1 23 38 0 0 0 1 ,2.... iam lost !:confused:

I think I've suggested several times now that you abandon this project, it is obviously beyond you. What else did you expect it to do ? You've done one part of what I said, although not quite how I said it, and shown the strings on the screen, what else could happen without more code to do it ?

u are right mr Graus ..i just wanna to thank u specially for ur effort with me ..god bless u my brother ; its the last time to ask about this project ..i swear . cheers;);
Well, don't give up entirely. Just work through some other stuff so you're better able to understand the advice you're being given. I'm still trying to help, not to shoot you down in flames.
