I'm testing out a CMS I've built in ASP.NET and I'm having issues validating a form textarea with a regular expression.
I've used a ReguarExpressionValidator control to make sure a maximum of 4000 characters are entered but have realised I'm not including line breaks in the regular expression and can't figure out how to include them?
I would like to know what the expression for "letters only" is for my asp.net web application. I tried ^[A-Za-z] but it does not work I would also like a regular expression for "numbers only except "-"
I have a text box which accepts CVV code of 3 or 4 numbers and im using regular expression validator this is wat im using : is this correct way of using or not
I'm trying to use a RegularexpressionValidator to match an IP address (with possible wildcards) for an IP filtering system.I'm using the following Regex:
"([0-9]{1,3}\.|\*\.){3}([0-9]{1,3}|\*){1}"
Which works fine when running it in LINQPad with Regex.Matches, but doesn't seem to work when I'm using the validator.Does anyone have a suggestion as to either a better Regex or why it would work in test but not in situ?
I was doing some web scraping and i was looking for some div elements with particular class names and markup. This is my objective , i have to extract everything within the div having the class s_specs_box s_box_4 Could someone provide the regular expression in .NET terms (i.e., which can be straight away passed into Regex's constructor)to match one such div (given below)
<div class="s_specs_box s_box_4"><h3>Display</h3><ul><li><strong><span class='s_tooltip_anchor'>Display:</span> <span class='s_tooltip_content'><p class='s_help'><b>Display</b> - Phone's main display</p></span></strong><ul> <li class='clear clearfix'><strong><span class='s_tooltip_anchor'>Type:</span> <span class='s_tooltip_content'><p class='s_help'><b>Type</b> - Refers to the type of the display. There are four major display types: Greyscale, Black&White, LCD:STN-color and LCD:TFT-color</p></span></strong><ul><li>Color</li></ul> </li><li class='clear clearfix'><strong><span class='s_tooltip_anchor'>Technology:</span> <span class='s_tooltip_content'><p class='s_help'><b>Technology</b> - Refers to the type of the color displays. There are five major types: LCD, TFT, TFD, STN and OLED</p></span></strong><ul><li>Super AMOLED</li></ul>..............................
I use some code to encrypt & decrypt string in C# but i want a good one that can generate encrypted string that contain only letters or numbers not any other ( + , / , ...)
i have a textbox in my web form and i want to input any word with any character. so, only i want to check length of textbox less than 200 character. how can i do it with regular expression? and if i want to block some character how can i do it?
I Would like to write a custom regular expression where the format is like XYZ-ABC-001 where XYZ is fixed, ABC is variable (it can be any three characters between A-Z )001 is variable (it can be any number between 0-9)
i need to write a regular expression for float value (5,2)
As per my understanding (5,2) means
Total length cannot exceed 5 digits i.e. 999.99
Digits before decimal is 3 and after decimal is 2 i.e. 999.99
I wrote this: ValidationExpression="(^d{0,3}[.]?d{0,2}$)" but this is accepting 9999 and 99999 which is wrong because in both case before decimal is more than 3 digits.
in my web application i want to validate that user can enter only digits and the digit may be a integer or decimal how can i write the regular expression for this.
I am trying to match a username to a userid which are in 2 different sql tables. Here is my select statement:
SELECT aspnet_Users.UserName FROM aspnet_Users INNER JOIN aspnet_starterkits_Projects ON aspnet_Users.UserName = aspnet_starterkits_Projects.ProjectManagerId
When I run this i get an error message: "Conversion failed when converting from a character string to uniqueidentifier" Is there anyway around this? Or a different select statement etc?
I'm writing a SQL query where I need to detect if the value of an integer column in one table is contained within the value of a varchar column of another table. For example:
Table1 has columns A, B, C
A = 1
B = 2
C = 3
Table2 has columns D, E, F
D = "1,2,3,4,5"
E = "2, 5, 10, 15"
F = "1, 3, 49"
How would I write SQL SELECT statement to determine if the value in Table1.A is in Table2.D, Table1.B is in Table2.E, and Table1.C is in Table2.F?
I am really struggling with this! Using the regular expression validator I created an expression, thus ":" to show an error message if the user tries to enter in a name that contains a colon. What I am getting is the error message showing even when there is no colon (:) in the string. What am I doing wrong?
