hi all i saw your solution and i have an assignment with the same idea but iam alittle confused about it .. may u can help me
this is the assignment
In this assignment you will required to build a sample form which reads its content from a text file. The format of the text file is as following:
Line1: will contain the Text property of the form
Line 2-to the end of the file: Each line will define a Control to be added to the form in the following format
Control Type, Text Property, X axis Location, Y axis Location
For example if the file contains:
Hello World
Text, Welcome, 10, 10
Button, Go, 100, 100
Label, Hi, 100, 200
Button, Click Here, 100, 100
This will show a form with Title “Hello World�with two buttons, one label, and one text box inside it.
Your code must detect any error in the input file and shows an appropriate message. This can be done by using try/catch and giving appropriate message.

Below are some pointers for an easy way to do it. Try doing it.
- Read the first line and assign the text property of the form with that value. Make use of StreamReader to read the file.
- split the next line based on comma and iterate through it.
- Compare the first element. If its a button, create a new instance of the button class.
- assign the second element with the Text Property of the newly created button.
- Assign the coordinates with the next value
- Add the newly created controls to the Form.Controls collection.

public partial class Form1 : Form
{
private TextBox textBox1;
public Form1()
{
InitializeComponent();
OpenFileDialog op =
new OpenFileDialog();
op.ShowDialog();
string path = op.FileName;
FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read);
StreamReader r = new StreamReader(fs);
this.textBox1 = this.textBox1 = new System.Windows.Forms.TextBox();
textBox1.Text += r.ReadLine();
string n;
while ((r.Peek () >-1))
{
n = r.ReadLine();
}
this is my trial :)

After you haveallthe lines in an array, go through it one by one to do your functionality.

blog.ganeshzone.net | | Ganesh Ranganathan - Bangalore, India Sunday, October 18, 2009 10:54 PM | could u write a sample code to get clear :)
thank u | | flower89 Sunday, October 18, 2009 10:56 PM |
string[] _allLines = File.ReadAllLines(path);
foreach (string _tempString in _allLines)
{
//Check if its the first line. Use a counter variable for it.
//else for all other lines, split the line with comma,
//and then iterate through the new array and follow the steps
//in my above post
}
Try this above code. Follow the steps in my above post.

This code is justto give a rough idea.Will have to modify this a little bit to make it work.
public Form1()
{
InitializeComponent();
OpenFileDialog op =new OpenFileDialog();
op.ShowDialog();
string path = op.FileName;
FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read);
StreamReader r = new StreamReader(fs);
int linecount = 1;
string linevalue;
// Read the text file line by line.
while((linevalue=r.ReadLine()) != null)
{
//first line in text file(linecount=1)
if(linecount==1)
{
Form1.title=linevalue;
}
else
{ //splitting the 2nd,3rd,4th lines from the text file
string[] words=linevalue.Split(',');
if words[0]=="Text"
{
TextBox tb=new TextBox();
tb.Text=words[1];
//will have to convert word[2] & word[3] to integer
tb.Location=New Point(word[2],word[3])
Form1.Controls.Add(tb);
}
if words[0]=="Button"
{
Button btn=new Button();
btn.Text=words[1];
btn.Location=New Point(word[2],word[3])
Form1.Controls.Add(btn);
}
if words[0]=="Label"
{
Label lbl=new Label();
lbl.Text=words[1];
lbl.Location=New Point(word[2],word[3])
Form1.Controls.Add(lbl);
}
}
linecount++;
}
r.Close();
}
