How to convert from Arabic numbers to English numbers

How to convert from Arabic numbers to English numbers - c#

When someone puts arabic numbers in my entry , it ends the app .
I'm trying to restrict entry to show only English number or convert arabic number to english
I'm trying it on real device and not working at all unfortunately .

You could try this method to convert it:
private string convertArabic(string arabicNum)
{
var chArr = arabicNum.ToCharArray();
var sb = new Java.Lang.StringBuilder();
foreach (var ch in chArr)
{
if (Character.IsDigit(ch))
{
sb.Append(Character.GetNumericValue(ch));
}
else if (ch == '٫')
{
sb.Append(".");
}
else
{
sb.Append(ch);
}
}
return sb.ToString();
}

binary search built in method is not working for my window form program c#

I created a program that uses both linear and binary search method. I use string array.
private void linearSearch_Click(object sender, EventArgs e)
{
string target = linearSearchBox.Text;
bool found = false;
for (int x = 0; x < myArray.Length; x++)
{
if (myArray[x] == target)
{
displayBox2.Text = target + " Found at index " + (x + 1) +
"\r\n";
linearSearchBox.Clear();
linearSearchBox.Focus();
return;
}
}
if (!found)
{
displayBox2.Text = "Not Found, try again." + "\r\n";
linearSearchBox.Clear();
linearSearchBox.Focus();
}
}
this will work, however the binary doest not
private void BinarySearch_Click(object sender, EventArgs e)
{
Array.Sort(myArray, 0, emptyPtr);
SearchArray(myArray, binarySearchBox.Text);
}
private void SearchArray(Array array, object value)
{
Array.Sort(myArray, 0, emptyPtr);
string target = binarySearchBox.Text;
int numIndex = Array.BinarySearch(array, target);
if (numIndex < 0)
{
displayBox2.Text = "The element to search for " + target + " is not found.";
}
else if(numIndex >= 0)
{
displayBox2.Text = "The element to search for " + target+ " is at index: " + numIndex;
}
}
test1 test2

Note that the code is performing a binary search in the text box of binarySearchBox, not the value in the text box of ListBox1.
The code that needs to convert the value added to ListBox1 into an Array array for storage.string[]myArray = listBox1.Items.Cast<string>().ToArray();,then search for ListBox1.
Code show as below:
private void BinarySearch_Click(object sender, EventArgs e)
{
string[]myArray = listBox1.Items.Cast<string>().ToArray();
Array.Sort(myArray, 0, emptyPtr);
SearchArray(myArray, binarySearchBox.Text);
}
private void SearchArray(Array array, object value)
{
string[] myArray = listBox1.Items.Cast<string>().ToArray();
Array.Sort(myArray, 0, emptyPtr);
string target = binarySearchBox.Text;
int numIndex = Array.BinarySearch(array, target);
if (numIndex < 0)
{
displayBox2.Text = "The element to search for " + target + " is not found.";
}
else if (numIndex >= 0)
{
displayBox2.Text = "The element to search for " + target + " is at index: " + numIndex;
}
}
private void linearSearch_Click(object sender, EventArgs e)
{
string[] myArray = listBox1.Items.Cast<string>().ToArray();
string target = linearSearchBox.Text;
bool found = false;
for (int x = 0; x < myArray.Length; x++)
{
if (myArray[x] == target)
{
displayBox2.Text = target + " Found at index " + (x + 1) +
"\r\n";
linearSearchBox.Clear();
linearSearchBox.Focus();
return;
}
}
if (!found)
{
displayBox2.Text = "Not Found, try again." + "\r\n";
linearSearchBox.Clear();
linearSearchBox.Focus();
}

loading large text file into richtextbox c# [duplicate]

This question already has answers here:
C# - Read in a large (150MB) text file into a Rich Text Box
(2 answers)
Closed 1 year ago.
I have a large text files for example 39000 lines and above , i want to load it into richtextbox , using normal way like this:
Richtextbox1.Text=File.ReadAllLines(file);
or
Richtextbox1.LoadFile(...);
it take long time and freeze the UI even i use BackgroundWorker, so i decide to split file into parts each part is 1000 lines and append them to the richtextbox , i mean i read 1000 lines from file into string and then append it to the richtextbox, here is my code:

the problem is that the code work fine with some file say less than 1000 but when i use large file has size greater than 1000,the count of lines is less than actual file lines
for example i attach text file
my text file
which has size 62077 but the after use my code the richtextbox lines is 62028, and count of characters also is less the actual count of characters of file, but the start and the end of content in richtextbox and file are the same, i do not know where is the error, all i want is to read text file , combine every 1000 lines in one string append it the richtextbox repeat the operation until end of file content.
i do not want to use Richtextbox1.LoadFile(...)and Richtextbox1.Text=File.ReadAllLines(file); because they freeze and hung the UI this happen when using large files more than 39000 lines,
i want to know what is the wrong with code?why dose not get right result?
i hope you help me.

i use this code and it work fine:
private void Worker_DoWork(object sender, DoWorkEventArgs e)

Event is not firing for the first time

In RichTextBox, I'm trying to fire an event with pressing period ('.') But It's not working for the first time.
If I write "Lorem Ipsum.", It's not working but If I write "Lorem Ipsum ." or "Lorem Ipsum.." It's OK.
PS: I've added the KelimeGuncelle method and GetWordGroupInstances() dictionary also.
Here's the block:
private void rtbMakale_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.OemPeriod)
{
kelimeGuncelle();
}
}
The kelimeGuncelle method:
void kelimeGuncelle()
{
Dictionary<String, int> TekliKelimeGruplari = GetWordGroupInstances(1);
foreach (var item in TekliKelimeGruplari)
{
for (int i = 0; i < lstKelimeler.Items.Count; i++)
{
var kelime = lstKelimeler.Items[i];
string guncellenecekKelime = kelime.ToString().Remove(kelime.ToString().IndexOf(" ( ") - 1);
string gelenKelime = item.Key;
string _guncellenecekKelime = kelime.ToString();
int pFrom = _guncellenecekKelime.IndexOf("(") + 1;
int pTo = _guncellenecekKelime.LastIndexOf("/");
int guncellenecekSayi = Convert.ToInt32(_guncellenecekKelime.Substring(pFrom, pTo - pFrom));
int kFrom = _guncellenecekKelime.IndexOf("/") + 1;
int kTo = _guncellenecekKelime.LastIndexOf(")");
int toplamYazilacakSayi = Convert.ToInt32(_guncellenecekKelime.Substring(kFrom, kTo - kFrom));
int kelimeninSirasi = lstKelimeler.Items.IndexOf(kelime);
if (Equals(guncellenecekKelime, gelenKelime))
{
guncellenecekSayi = item.Value;
lstKelimeler.Items.RemoveAt(kelimeninSirasi);
lstKelimeler.Items.Insert(kelimeninSirasi, guncellenecekKelime + " ( " + guncellenecekSayi + "/" + toplamYazilacakSayi + " )");
//lstKelimeler.Refresh();
}
if (rtbMakale.Text.Contains(guncellenecekKelime) == false)
{
lstKelimeler.Items.RemoveAt(kelimeninSirasi);
lstKelimeler.Items.Insert(kelimeninSirasi, guncellenecekKelime + " ( 0/" + toplamYazilacakSayi + " )");
//lstKelimeler.Refresh();
}
}
}
TekliKelimeGruplari.Clear();
}
And GetWordGroupInstances:
Dictionary<String, int> GetWordGroupInstances(int GroupSize)
{
Dictionary<String, int> WordGroupInstances = new Dictionary<string, int>();
String[] sourceText = GetSourceText().Split(' ');
int pointer = 0;
StringBuilder groupBuilder = new StringBuilder();
while (pointer < sourceText.Length - GroupSize)
{
groupBuilder.Clear();
int offset = pointer + GroupSize;
for (int i = pointer; i < offset; i++)
{
groupBuilder.Append(" ").Append(sourceText[i]);
}
String key = groupBuilder.ToString().Substring(1);
if (!WordGroupInstances.ContainsKey(key))
{
WordGroupInstances.Add(key, 1);
}
else
{
WordGroupInstances[key]++;
}
pointer += 1;
}
return WordGroupInstances;
}

try using a MessageBox.Show("Test"); for testing , maybe something in your kelimeGuncelle() method is wrong.
private void rtbMakale_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.OemPeriod)
{
MessageBox.Show("Test");
}
}

I got it!
In the GetWordGroupInstances, I've changed the while loop. Here:
while (pointer <= sourceText.Length - GroupSize)

UI not updating from asynchronous event

i use the Asynchronous socket Client event to receive message from server.
i receive message from client DataIn(my Event Name) and add to list box ,but not happen to show on UI!
protected void WebSocketClientControl1_OnChatNotification(List < SocketUi > sender) {
ClientScript.RegisterStartupScript(GetType(), "hwa", "javascript:__doPostBack('WebSocketClientControl1','')", true);
}
i cant use the (Response.Redirect & Server.Transfer).
this 2 function have error run time.
i call the javaScript function to show message , not happen on screen.

its my Socket code
