I need to allow specific characters in my textbox but not range of letters only those ( T, A, G, C ).. the problem is I can't find the regular expression pattern for that.
I think you can make it just with /[TAGC]/g.
I strongly recommend you to check out this site, you can test every regular expression you need there:
RegExr

The questions I saw here is mostly about getting current input layout, but I need list of all installed input layouts.
It's like when we install Windows we choose additional input method for our native language and we usually has 2 of them. And I need to know it.
foreach (InputLanguage c in System.Windows.Forms.InputLanguage.InstalledInputLanguages)
{
Console.WriteLine(c.Culture.EnglishName);
}

I am trying to create a validation expression for a table name in the format of:
Name_TableName_YYYYMMDD
right now I have something like this:
^[a-zA-Z0-9][^_]+[a-zA-Z0-9][^_]+\d{8}
Number at the end can read 8 digits.
You could try this (very basic) expression
[a-zA-Z]+_[a-zA-Z]+_[0-9]{4}(0[1-9]|1[0-2])(0[1-9]|[1-2][0-9]|3[0-1])

I saw this post in internet about the restrictions on Skype name
A Skype username cannot be shorter than six characters or longer than
32. It can contain both letters and numbers, but must start with a letter; accented characters are not allowed. The only punctuation
marks you can use are commas, dashes, periods and underscores.
What is the regular expression that restrict these rules in C#?
Regards
maybe you can try this:
/^[A-Za-z\d\,\-\.\_]{6,32}$/
EDIT: make alphabets case-insensetive

I am trying to write a regex template that matches all the strings that doesn't contain a certain template.
E.g.:
Matches:
This is my friend. He is very nice.
in
This is my friend. He is very nice.
but doesn't match anything in :
This is my friend John Michaels Fredrickson. He is very nice.
Because it contains something like this: ([A-Z][a-z]+\s?){3}
You can use negative lookahead:
^(?!.*?([A-Z][a-z]+\W){3}).*$

You can probably make use of a library such as ScoreSharp. It is designed to do fuzzy matching to find similarities between strings.
