Hello Dear Mr Jibin Pan,
I have just downloaded your sample code "Masked C# TextBox Control" from Csharphelp.com and from here too.
I'm from iran and here we use PersianDate format (Shamsi).
recently I'm working on an Accounting Application in wich date field is frequently used, and your Control is EXACTLY what i was looking for !!!
Since your control dose not support (shamsi) date i can not use it.
I have tried to change its format but i got Confused !!!
So I want you to help me on this, and change (only the Date format) of this control as the following format:
------------------------Persian Date Format
public readonly short[] Persian_Month_day = { 31, 31, 31, 31, 31, 31, 30, 30, 30, 30, 30, 29 };
private bool CheckDayOfMonth_Pr(int mon, int day)
{
if (day > Persian_Month_day[mon-1] || day == 0)
return false;
else
return true;
}
------------------------------------------
yyyy/mm/dd like "1386/08/20" or "86/08/20"
year starts with "1" or "13" like "1386"
------------------------Persian Date Format
I appreciate your help.

Look for something called Expresso it is a tool someone told me to use and now I never code without it.

This is regarding the PhoneWithArea Mask..if you start using the backspace from '-' i.e. middle of the string..you can type endless characters )

Suppose I want to use this in what I imagine is almost the simplest possible scenario.
I have a very simple stateless list of characters that I will allow, let's say [A-Za-z!@#$%].
How do I set the masked text box to allow only and any of those characters, and no other?
I cannot find any decent documentation on MSDN, except silly little examples about how to do social security numbers. Maybe I'm just not looking in the right places.
(Moving beyond the simplest possible use, the next question would be how to do context-dependent regular expressions, ya?)

Very usefull control!
It would be perfect if Copy/paste was also implemented with the mask function.

the mask for an IP adress is :
#^([O1]?\d\d?|2[0-4]\d|25[0-5]).([O1]?\d\d?|2[0-4]\d|25[0-5]).([O1]?\d\d?|2[0-4]\d|25[0-5]).([O1]?\d\d?|2[0-4]\d|25[0-5])$#
(I don't test it but I think it's ok)
details : ([O1]?\d\d?|2[0-4]\d|25[0-5]) : - number like 0 - 199
Or number like 200 - 249
Or number like 250 - 255

Sometimes a user will pass over the masked text box not having an entry. Throughout the session the red exclamation icon remains on.
Is there a way I can clear/reset the Error Provider icon?

Well I finally figured out a way to clear the error provider icon.
You just have to enable = false; refresh; enable = true; refresh the control and it goes away.
Kind of clumsy would perfrer a mehtod to clear.

I know it is some time since you asked the question, but it may be useful for new readers
I have solved this by adding a new function to the class, called ResetError
public void ResetError()
{
this.errorProvider1.SetError(this, "");
}
and then calling it from my code
ie
this.txtBox.ResetError();
Hope it helps

Hello! The german date format is dd/mm/yyyy
How can I get the control to work with this format?
I tried to understand the C# code, but...
BTW: The locales are "germen" already (as told in another thread).

Hello,
I hope my code will fit in this reply. This is code I found on the codeproject site but I changed it to dd/mm/yyyy format.
There are two porblems with it :
- you can not go in override mode, to change the day you need to use backspace till the beginning and then put in the data completely again.
- If you use backspace to far, you will get a runtime error.
Hope it helps, any comments are apreciated

Control work properly only if I put digit in sequence from left to right.
If I insert a date and then I change the day or month, the control don't process correctly new digit.

Hi Everybody,
The new src code include the changes:
you can insert char in the middle of the string
you can replace the selected string with new type in char
you can delete char in the middle of the string using backspace key.
the decimal can have negative number.
Thanks for all the people who like the control.
Regards
Jibin Pan

I suppose it's easy for someone who studied (or wrote) the date only code. There are a lot of nested if-structures...
thx
