I can help you once you have a clear description of the problem, and come up with specific questions. When related to animations, I will assume you have read my article.

Simulation algorithms FCFS (first come first served) - CPU scheduling:
Input: process name, arrival time, burst time
Output: average waiting time, Gantt chart showing the process of how work, simulation of processes running on the CPU with the graphics.
If you help me, I thank you!

You are not getting it, are you? You study the domain, you do your research, you use google, you try a couple of things, and then, when you are stuck, you can ask specific questions, and people here will be glad to help you. But we don't do your project for you.

I have calculated the average waiting time and Gantt chart.
Now I want to simulate.
How can a rectangle appear in some time.
Example: I want a rectangle appears at 3 seconds for 6 seconds. rectangle appears when the rectangle that is filled from left to right until the end.
While the original rectangular bowl is 5 seconds, then at the first two rectangles appear

Are you talking about real time (i.e. using timers), or a time axis on a chart?
You can draw a rectangle on any control by handling its Paint event, or if it's a custom control, in the OnPaint method. Have a look at the Graphics class[^].

I refer you to Luc's post[^]. No-one is going to code your solution for you. Go away, read about the things you need to know, and work out how to do what you want to do.
If you get close and have some small, specific issues that you can't resolve yourself, that is when to ask questions. 'lolol code dis 4 me' is just going to get you disliked.

This Code is working well but wrong. Wrong because it lower all text -because of the MatchCase method.
How can I make it work without pre-changing anything inside (exception for color text to find)?
int posTxt = 0;
private void button2_Click(object sender, EventArgs e)
{
string searchText = textBox2.Text.ToLower();
string alltxt = richTextBox1.Text.ToLower();
if (alltxt.Contains(searchText))
{
richTextBox1.Text = alltxt;
while (posTxt != -1)
{
posTxt = richTextBox1.Find(searchText, posTxt, RichTextBoxFinds.MatchCase);
if (richTextBox1.SelectedText == searchText)
{
richTextBox1.SelectionLength = searchText.Length;
richTextBox1.SelectionColor = Color.Red;
}
posTxt = richTextBox1.Find(searchText, posTxt + 1, RichTextBoxFinds.MatchCase);
}
}
posTxt = 0;
}

You could use the lower-case versions of the search string and the text to locate the match (or matches); then remove whatever exists at the match position (you know position and length), and then insert the new text with its original casing.

please read my reply again: you search using the lower-case versions, only to find the location.
you modify using the actual text, not the lower-case one (the positions are the same for both!)

this is what i have done so far... but with the same result. The text in richTextBox1 is changing to lower and I dont see from where.
int posTxt = 0;
private void button2_Click(object sender, EventArgs e)
{
string searchText = textBox2.Text.ToLower();
string alltxt = richTextBox1.Text.ToLower();
RichTextBox rtb = new RichTextBox(); rtb = richTextBox1;
if (alltxt.Contains(searchText))
{
rtb.Text = alltxt;
while (posTxt != -1)
{
posTxt = rtb.Find(searchText, posTxt, RichTextBoxFinds.MatchCase);
if (rtb.SelectedText == searchText)
{
richTextBox1.SelectionLength = searchText.Length;
richTextBox1.SelectionColor = Color.Red;
}
posTxt = rtb.Find(searchText, posTxt + 1, RichTextBoxFinds.MatchCase);
}
}
posTxt = 0;
}

yes... but...
only rtb.Text = richTextBox1.Text; not inverse.
RichTextBox rtb = new RichTextBox(); rtb = richTextBox1;
meaning:
richTextBox1.Text is not equal with rtb.Text.
anyway... its not about the new rtb.

WRONG!
you have copied the reference, so both rtb and richTextBox1 point to the same object.
the new RichTextBox you also created is dead right away, it is never used (it also is not needed!).
BTW: Eric already told you all that.
I suggest you choose, buy and thoroughly study an introductory book on C#.

As told earlier by Luc, rtb and richtextBox1 refer(point to the same object).
Think of it this way: rtb and richtextbox1 are just some names that help you deal the the real thing.
A guick fix for what you are trying to do with this line of code would be:
RichTextBox rtb = new RichTextBox(); rtb.Text = richTextBox1.Text;
Now rtb does not point to the same object but it just copied the text from richtexbox1.
Clearer than that I don't know how to explain.
All the best,
Dan

As Luc has already suggested:
Do not assign alltxt to rtb.Text nor richTextBox1.Text; Actually, remove rtb variable, you don't need it;
Use alltxt.IndexOf method instead of rtb.Find method to search for the text you want. The indexes will be the same.
Use these indexes to make the changes on your rich text box control.
The lines:
RichTextBox rtb = new RichTextBox(); rtb = richTextBox1;
are useless becouse RichTextBox is a reference type, so your local rtb variable and your richTextBox1 will both be pointing to the same object.

in some desperation I was using "RichTextBox rtb " variant, copying its locations to the real one...
But I managed to find the solution after all.
Thanks!

richTextBox1.Text = alltxt;
Why are you doing that? You are explicitly setting the text to the lower case version in that line. The only difference between the text property and alltxt is that you ran ToLower on alltxt!
Also, RichTextBox.Find, if you want to use it, already searches case-insensitively by default. Did you read the documentation for RichTextBoxFinds[^]? Passing RichTextBoxFinds.None will cause the search to be case-insensitive – you explicitly asked for a case sensitive one, for some reason.

Problems Solved:
Sincerely, I did changed RichTextBoxFinds.None before posting here on forum, but for some strange reason, it did not work back then... Now it works fine.
I have another problem...see it beneath code.
Here is the functional code:
int posTxt = 0; string tempText = "";
private void button2_Click(object sender, EventArgs e)
{
richTextBox1.Text = tempText;
string searchText = textBox2.Text.ToLower();
string alltxt = richTextBox1.Text.ToLower();
if (alltxt.Contains(searchText))
{
if (posTxt <= 0)
{
richTextBox1.Text = richTextBox1.Text.Insert(0, " ");
posTxt = 1;
}
while (posTxt > 0)
{
posTxt = richTextBox1.Find(searchText, posTxt, RichTextBoxFinds.None);
if (richTextBox1.SelectedText.ToLower() == searchText)
{
richTextBox1.SelectionLength = searchText.Length;
richTextBox1.SelectionColor = Color.Red;
}
posTxt = richTextBox1.Find(searchText, posTxt + 1, RichTextBoxFinds.None);
}
}
posTxt = 0;
}
But i have a little problem now...
If I load a *.rtf file with formatting text and search a word in that richTextBox1 that show that file, the text is re-formatting, loosing its original format.
How to maintain its original format, and select as usual(with red marking)?

I found the following sp on this website, when I run it by right clicking on the procedure in the DB using the command "Execute Stored Procedure" it works fine. However, when I run the sp from C# I get the following error:
//err.Message = "Microsoft SQL Native Client:
//CONFIG statement cannot be used inside a user transaction.\\42000 = 574;
//Microsoft SQL Native Client: Configuration option 'show advanced options'

Can anyone tell me what the problem is.
Thanks in advance,

This may get a faster answer if posted to the Database forum, there does not seem to be a C# issue here.

Is there a way to somehow disable or remove the ProductVersion component of some of the "Application" object properties such as the "UserAppDataRegistry" property?
Application.UserAppDataRegistry =
CurrentUser\Software\CompanyName\ProductName\ProductVersion

Ho do you test to ensure that the first character/digit in a string is a positve number? ie. 1 to 9, instead of -1 to -9.
Everything makes sense in someone's mind
