Fast access for your controls (C# code).

The original thread is here
There you can see the source code and tweak it!
Moreover you may post here questions, different opinions etc..
Hope it helps

Well if you place all the text boxes in own container you could probably save a cycle or two by avoiding additional conversion while calling the Read method or not call additional method altogether. Also you should probably kill the loop if your iterations are exceeded to not go thru controls that are irrelevant to your measurement count value. Not critical when you have relatively few controls but still why waste CPU time:

foreach ( TextBox iBox in this.MyTBPanel.Controls ){
    try {
        // Add value to sum
        sum += Double.Parse(iBox.Text);
    } catch {
        // Set flag 4 invalid entry
        flag = false;
        // Quit here - no point going further
        break;
    }
    if ( index++ > measurements )
        // Quit loop here - no point iterating further
        break;
}
if ( flag ){
    // Something for the flag
} else {
    // Something for error
}

Similarly to clear things up

foreach ( TextBox iBox in this.MyTBPanel.Controls )
    // Reset box value
    iBox.Text = "";

// Reset combobx value
comboBox.Text = "1";

Are you dynamically creating textboxes in your form or are they all created at design time?

No I don't but thanks for suggestion it is advanced for me cos I started learning Windows programming two years ago honestly I am not a professional programmer.
If I change the next edition of the code as you mentioned then its size will be smaller.
AtomicMonkey thanks for the code.
My approach is to finish as soon as possible (not enough free time) the most parts and then I will tweak it more.
