c# - Implement Date Time Picker functionality with MaskedTextBox. Validation done with RegEx -


I am trying to create a custom control specifically for my application which prohibits the input data entered Will use the masked textbox for.

Now I want to implement it in C #. 

  Class CustomDateMask: System.Windows.Forms.MaskedTextBox this.Mask = "00/00/2 \ 000"; For the year 2000 and above, the date format is "dd / mm / yyyy". Type of verification = type (system. Datam);

I have seen a regular expression to validate my date by limiting the date by leaving the entry and capturing the events of the Capperes.

Now my RegExp is going to be like this

string regaire = @ "(200 [8 9] | 201 [0-9])"; // If this is incorrect for the year from 2008-2019, then correct this RegEx. String regMonth = @ "(0 [1- 9] | 1 [012])"; String regDate = @ "(0 [1-9] | [12] [0- 9] | 3 [01])"; String separator = @ "[- /]"; String ddmmyyyy = regDate + seperator + regMonth + separator + regair;

I saw a regarding the regular expression for the date format check. Now I want to use this code in C # which I gave you in the link given above. This code is written in pearl and I want to have the same functionality in C #. But I do not know how to remove the date, month, year from this regular expression extracted in the examples given below. $ 1, $ 2, $ 3 to 

  sub-defined {my $ input = shift; If ($ input = ~ m! ^ ((?? | 19 | 20) \ d \ d) [- /.](0] [1-9] [1] [2] [2] [2] [2] ] [] - /.](0 [1] 9] | [12] [0-9] | 3 [01]) $!) {# At this point, $ 1 entered the year, $ 2 months and $ 3 Are kept on the date of the date ($ 3 ==31 and ($ 2 == 4 or $ 2 == 6 or $ 2 == 9 or $ 2 == 11)) {return 0; one month with 30 days Alsuf ($ 3> = 30 and $ 2 == 2) {return 0; # 30th or 31st} ALLECIF ($ 2 == 2 and $ 3 == 29 and not ($ 1% 4) == 0 and ($ 1% 100! = 0 or $ 1% 400 == 0))) {return 0; # February 20} outside the leap year Second {return 1; # valid date}} and {return 0 ; # Date not}}

I use I want to use the date part, the part of the month and the part of the year. The date is only, this. Only the mother, this year only for which I need to remove these values.

My main concern

Masked text box

Enter the date, year, month and day entered in three variables with $ 1 , $ 2 , and $ 3

is equal to C # Of m.Groups [1]. Value , m.Groups [2]. Value , and so on.

In your example, to remove them, you 

  match me = regesx. Will use the match (ddmmyyyy); If (m.Success) {string day = m. group 1]; String month = M. Group [2]; String year = m. Group [3]; }

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
