Thanks..for the advice, i will really use that next time

Its a RichtextBox and may be when you see the codes, you will understand me. Its actually a application that compares the text in RichtextBox1 to the text in RichtextBox 2. It then highlights the diffrent portion in richtextBox2. Have been able to do that, except that it highlights the first occurence of the diffrent text. Here is the code....


public void check()
{
string[] RichTextBoxLines1 = dragDropclass1.Lines;
string[] RichTextBoxLines2 = dragDropclass1.Lines;

List<string> Test1 = new List<string>(dragDropclass1.Text.Split(new char[] {' '}));
List<string> Test2 = new List<string>(dragDropclass2.Text.Split(new char[] {' '}));

if (Test1.Count > Test2.Count)
{
for (int i = 0; i <= Test1.Count - Test2.Count; i++)
{
Test2.Add(" ");
}
}
else if (Test2.Count > Test1.Count)
{
for (int i = 0; i <= Test2.Count - Test1.Count; i++)
{
Test1.Add(" ");
}
}



bool[] value = new bool[Test1.Count];
for (int i = 0; i < Test1.Count; i++)
{
string a = Test1[i];
string b = Test2[i];
value[i] = string.Equals(a, b, StringComparison.Ordinal);

}


for (int i = 0; i < value.Length; i++)
{
if (value[i] == false)
{
int k = i + (i - 1);

// int s = dragDropclass2.Text.IndexOf(Test2[i], Test2[i].IndexOf(Test2[i]),Test2[i].Length);
dragDropclass2.SelectionStart = dragDropclass2.Text.IndexOf(Test2[i],k);
dragDropclass2.SelectionLength = Test2[i].Length;
dragDropclass2.SelectionColor = Color.Red;

}


}

Test1.Clear();
Test2.Clear();

}

Where Dragdropclass are the control i created to enable me drag text file into the richtextBox.

The thing is, The text are dynamic text, and it might even actually be numerous of lines of text...
What am working on is something that identifies the diffrent portion of another text. have been able to do that. But instead of highlighting the Text at the exact position, it highlights the first occurrence of that Text.

i could detect they were diffrent, but i could not count the number of diffrences and i could not highlight them

Ok..i think i get u now. I tried using the methods i found in this link http://msdn.microsoft.com/en-us/library/vstudio/cc165449.aspx

Am trying to do a WPF application that will compare the text in RichTextBox1 to the Text in RichTextBox2, the highlight the different text in RichTextBox2
