Just a bit unnerved. I googled those filenames. Your questions show up as first results. Do you know what this probably means?

Hi I want to replace only 5 digit (not less than or not more than) to “xxxxx” with Regex
I tried -
InputString = "sample1: 12345 – sample2 : 123456789"
Dim regExp As Regex = New Regex("(\d{5})")
regExp.Replace(InputString, "xxxxx")
output - "sample1: xxxxx – sample2 : xxxxx6789"
But i want as "sample1: xxxxx – sample2 : 123456789"
if more than 5 digit , it must not replace.

Add a whitespace and an "end-of-line" indicator:
Dim regExp As Regex = New Regex("\s(\d{5})$")And include the whitespace back in your replacement string.
And in future: post VB in the VB forum, and C# in the C# forum?
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

It was exactly a C# question and not VB. I wonder why this simple question have made all nervous! it was related to Fuzzy Logic and Fuzzy Expert Systems.
Anyway, thanks a lot for your all answers.

You have replied to someone else's question. The question that was asked here was written in VB.
|
|
|
|

If you look at the question I answered, you will see it is written in VB, not C#...
Dim regExp As Regex = New Regex("(\d{5})")

Try the built-in encryption routines, they'll be a bit safer than shuffling some values. If you want help with this specific algo, you'll probably have to explain some more; which encryption-algo are you trying to implement?
Also, you'd like to edit your post and put the code between "pre" tags to improve readability.

I didn't read your code, but just in case, in C# (and almost every C base language) when counting an array/index, the very first position of the array will be 0/zero, it is common to see something like this in a for
for (i = 0:i<=Array.Lenght -1;i++){
}
where you substract 1 to the Lenght of the array because even though the array length is 10 you start counting at 0 (0,1,2,3,4,5,6,7,8,9)

I have 2 text box in form 1 and 4 button + 1 text box in form 2
how I can show the form 1 text box in form 2 and use from their
value.(this is a calculator)
|
|
|
|
|
You can pass it to the form via a setter method, or use a delegate to communicate between them. It rather depends on the structure of your application.
|
|
|
|

how can i use from setter method ?
|
|
|
|
|
Define a string property in the Form class and use that.
public string ToBePassed
{
get; set;
}
form2.ToBePassed = TextBox1.Text;

I've got a Timer delegate described method as preparation for a double recursion work and second method with tiny optimized recursion only. I need to execute the recursion in async thread too. But NET.Framework dont do that, only do async preparation method and no recursion method.
C# code
using System.Threading.Timer
...
private void button10_Click(object sender, EventArgs e)
{//Timer
Elem ss = new Elem();//Elem is a structure.
ss.a = "string1";
ss.b = "string2";
TimerCallback timeCB = new TimerCallback(timerex);
System.Threading.Timer t = new System.Threading.Timer(timeCB, ss, 10000, 10000);
}
public static void timerex(object data)
{
string a1 = ((Elem)data).a;
string b1 = ((Elem)data).b;
MessageBox.Show(a1+" "+b1);
timerex2(a1,b1);
}
public static void timerex2(string s1,string s2)
{
MessageBox.Show("Method_in 2 "+s1+s2);
}
How to execute the recursion in async timer thread?
|
|
|
|

Ignoring that there isn't any recursion in your code, if I copy and paste your code into my app and try it - it works.
I get the first message box, then the second.
Then a delay, first message box, second message box.
Repeat until bored or I shut the app.
So what did you expect to happen?
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
|
|
|
|
|
Everything is correct. This is just a test, not a real program.To avoid any other mistake influences.
Did you get
MessageBox.Show("Method_in 2 "+s1+s2);?
Execution of the second method timerex2(a1,b1);
Has to be doubling messaging every 10 sec. Ive got only 1 message,10 sec and again one.
ps Could be my computer problem-VS2013.4-NETF.4.5,W8.1,intel proc

As I said, I got both message boxes, with a ten second separation.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

Since your message is missing:
"What shall i do? Report to Microsoft? Computer is clean, fresh reinstalled"
Um.
Having looked at your image, there are a few things you need to know...
A MessageBox is a modal dialog. That means that when you call the Show method, it doesn't return until the user (or the system) dismisses the dialog, normally by pressing a button.
So...this code:
string b1 = ((Elem)data).b;
MessageBox.Show(a1 + " " + b1);
timerex2(a1, b1);
Cannot call timerex2 until the dialog opened in the previous line has been closed.
This is not a bug: this is exactly what is supposed to happen. If you click on the "OK" button, you will get the second dialog, just as I did.
What are you trying to do?
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

You are right.
I put the MessageBox just as a checkpoint for new thread.Modal windows in new thread are not modal any more as for main thread.It was my fault with mixing modals as for local thread.
In normal situation i dont use messagebox.
My real fault was that description of delegate was inside in method. In end of method data was cleared and nothing happends.
But i fixed it already.
Thank you for help.
ps.Actually trying to fix it.
In local description doesnt need static method and it is working ok. In form class description ask static method
