    <p>I have two words:<br> Source: John<br> ConvertTo: Jack</p> <p>and I want to show the effect of convert all letters from "Source" at the same time to the "ConvertTo" word. I already create a program to accomplish that but processing one letter at a time, to show the effect I use Threads, the thing is that to process all letters at the same time I suppose I need one thread per letter, and every thread will call the same function that process the letter, and I use global variables.</p> <p>Here is the code (works only for texts with same lenght):</p> <pre><code>private void button1_Click(object sender, EventArgs e) { lblResult.Text = ""; lblResult2.Text = ""; ThreadPool.QueueUserWorkItem(new WaitCallback(Process)); } int movement = 0; string CumulateText; private void Process(object stateinfo) { int value; int operation; //0-&gt;[+] 1-&gt;[-] CumulateText = ""; for (int i = 0; i &lt;= textBox1.Text.Length - 1; i++) { if (textBox1.Text[i] != ' ') { value = (char)textBox1.Text[i] - (char)textBox2.Text[i]; if (value &gt;= 0) operation = 1; else operation = 0; for (int ii = 0; ii &lt;= Math.Abs(value); ii++) { if (operation == 1) movement = (char)textBox1.Text[i] - ii; else movement = (char)textBox1.Text[i] + ii; this.Invoke(new EventHandler(ShowMovement)); System.Threading.Thread.Sleep(10); } } CumulateText += textBox2.Text[i].ToString(); } } private void ShowMovement(object sender, EventArgs e) { lblResult.Text = CumulateText + Convert.ToString((char)movement); } </code></pre> <p>I hope I made myself understood. please any advise to accomplish that. thanks</p> <p>To clarify more what I want to accomplish here is an example:<br> Source: John<br> ConvertTo: Jack </p> <p>J - same J<br> o - decrease till a (o, n, m, ..., a)<br> h - decrease till c (h, g, f, ..., c)<br> n - decrease till k (n, m, l, k)</p>

    3. COStrings are immutable you can't 'replace' multiple letters in a string at the same time, you have to delete the old string and replace it with a new one every time. If you want to avoid this by magically replacing them 'at the same time' you should use a Stringbuilder and do it sequentionally instead.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
