As others have pointed out, there are many instances where notifying of changes isn't the best idea. Imagine this - both people are editing the same record and the first one saves her changes. What are you going to do now? Do you overwrite the edits the second one is making? Does he have to abandon his changes to see if they are no longer relevant and then re-enter because the first persons changes don't matter to him?
You need to decide what problem you are really solving first. Don't try to invent solutions to problems you haven't fully investigated yet.

Unfortunately, the whole point of OP's post (how to pass an alert between Windows apps) is getting derailed (again) with "side-bars"; this time to do with "update contention".
That's good though; usually it's SQL injection.

I disagree.
Update contention is a valid point, but not good enough to discard the original question, as I understand it.
(OP NEVER said he was dealing with updates from MULTIPLE sources).
And instead of simply telling OP he's out to lunch (maybe), I prefer he find it out for himself (based on any discussion).

You are correct. I should have re-read the question first.

I know you asked this a long time ago, but since this question originally triggered me in writing the article: What You See Is What You Update , you could find it interesting.

I am new to this concept and i am looking for control in toolbox which is similar to wizard functionality or you can say same as Multi-view(in web)
|
|
|
|
|
Take a look at the Panel and Tab controls in the toolbox.
|
|
|
|
|
If you are just trying to hold multiple controls under one parent control, then did you look into the TabControl [^]? It indeed is the toolbox for Windows Forms.
This Introduction to the Windows Forms TabControl[^] will help you to get started.

Do you mean the installer Wizard? If that is the case, then just use the Publish feature of Visual Studio. Publish Wizard[^].

I have dynamically created controls that I want to use to create and write an output file with.
How can I organize the controls values based on their name?
private TextBox txtBox1 = new TextBox();
private ComboBox cmbx1 = new ComboBox();
private TextBox txtBox2 = new TextBox();
private TextBox txtBox3 = new TextBox();
private Button btn1 = new Button();
int configLineIndex = 1;
private void btnCuRepairConfigAddLine_Click(object sender, EventArgs e)
{
configLineIndex++;
tbxHorizontalIndex = 21;
txtBox1 = new TextBox();
txtBox1.Name = "line" + configLineIndex + "a";
int tbxWidth = 285;
this.txtBox1.Location = new System.Drawing.Point(tbxHorizontalIndex, tbxVerticalIndex + 30);
this.txtBox1.Size = new System.Drawing.Size(tbxWidth, 20);
this.Controls.Add(txtBox1);
cmbx1 = new ComboBox();
cmbx1.Name = "line" + configLineIndex + "b";
this.cmbx1.Location = new Point(tbxHorizontalIndex + 299, tbxVerticalIndex + 30);
this.cmbx1.Size = new Size(121, 21);
this.cmbx1.Items.Add("addAfter");
this.cmbx1.Items.Add("addBefore");
this.cmbx1.Items.Add("Replace");
this.Controls.Add(cmbx1);
txtBox2 = new TextBox();
txtBox2.Name = "line" + configLineIndex + "c";
tbxWidth = 320;
this.txtBox2.Location = new System.Drawing.Point(tbxHorizontalIndex + 435, tbxVerticalIndex + 30);
this.txtBox2.Size = new System.Drawing.Size(tbxWidth, 20);
this.Controls.Add(txtBox2);
txtBox3 = new TextBox();
txtBox3.Name = "line" + configLineIndex + "d";
tbxWidth = 320;
this.txtBox3.Location = new System.Drawing.Point(tbxHorizontalIndex + 770, tbxVerticalIndex + 30);
this.txtBox3.Size = new System.Drawing.Size(tbxWidth, 20);
this.Controls.Add(txtBox3);
btn1 = new Button();
btn1.Name = "line" + configLineIndex + "e";
this.btn1.Location = new Point(tbxHorizontalIndex + 1110, tbxVerticalIndex + 30);
this.btn1.Size = new Size(20, 20);
this.btn1.Text = "X";
this.Controls.Add(btn1);
tbxVerticalIndex = tbxVerticalIndex + 30;
}

you could start by giving your controls meaningful names so anyone can better guess what they are used for. You can list all the controls on your form by something like:
foreach (Control cc in Controls)
{
}
See Control Class (System.Windows.Forms)[^] for Properties, Methods etc.

Suppose I want to allow users of my app to rank holidays by attaching a number to each of them, then I want my app to sort them, what is the easiest way of achieving this? Please see below
"Christmas"
"New Year"
"July Fourth"
"Thanksgiving"
"Veteran's Day"
"Valentine's Day"
I thought about concatenating a number to each string and then placing the strings in an array.
Then loop through the array, checking if the string in each array index contains a number.
Next sort the strings using bubble sort.
Finally remove the numbers from these strings.
Is this the easiest way of ranking and then sorting them or is there a better way?

Don't stick with a string. If I were doing this, I would look to put this in a structure something like this:
public struct DaySort
{
public string ImportantDate { get; set; }
public int SortOrder { get; set; }
public override string ToString()
{
return ImportantDate;
}
} By supplying an override of ToString, I can still just write out the item without having to specify ImportantDate outside of this structure, so I would still appear to be following the semantics of the string type that you are used to. Now, sorting is as simple as:
IOrderedEnumerable<DaySort> sortedList = myListOfDays.OrderBy(ds => ds.SortOrder);
