I have an entry from a database that has 500 characters. But when i display it i only want to return 200 charcters. How do I do that. I use Sql Server.
View 3 RepliesIt is always an issue while I import large text. After certain number of characters, it skips the rest of text!
View 2 RepliesI want to prevent the entry of two characters together but I want the user to be able to enter one or the other as well as use the enter key. I would like to use a white list instead of black listing characters. The regular expression also needs to support a min and max length. I'm doing client side validation using the asp:regularexpression control. I do not want to have to do server side validation unless that's the only solution to this problem. Has anyone else run into this?
Here is the regex I'm currently using:
(?!.(&#))^[a-zA-Z0-9!@#$%^&_=+~''"";:,
.()?-]{1,1000}$
I'm using a asp.net textbox that is set to multiline so I have to allow for

I want to keep the user from entering &# together but allow them to enter text with & or # in it and allow all of the characters a-zA-Z0-9!@#$%^&*_=+~''"";:,
.()?-.
A valid text entry would be as follows:
I have a question about my order. The order number is 12345.

is there a way to add an image in SQL server database entry

I'm going to have a textbox on my ASPX page - where users can enter a number between 1-50.
Based on their selection, I'd like to add three textboxes for each number and number them appropriately.
I'd like three textboxes for each "number", so for example, the fields would be:
Name1, PIN1, Desc1
Name2, Pin2, Desc2
Name3, Pin3, Desc3
...
So, how do I, at runtime, add these fields to my page?
Secondly, This form, upon submittal, creates a configuration file on my server currently in the format of
[FIELD1]
FieldOne.Value
[/FIELD1]
[FIELD2]
FieldTwo.Value
[/FIELD2]
[FIELD3]
FieldThree.Value
[/FIELD3]
With those fields, it's rather easy, as the form has static controls that I'm looking up and sending to my file.
How would I add the dynamic controls to the file as well? Obviously, if they've selected to add 10 fields, I don't want 40 other fields of blank/nothing (since they can choose to add up to fifty). How would I iterate only adding the fields that they've chosen?

I have 2 table in database 1-State 2-City and bind DropDownList 1-ddlstate 2-ddlCity from these table and when I select item from ddlsate , according to my selected item from ddlState , ddlcity's Item change I used OnSelectedIndexChanged for ddlstate
problem is: I enter some data in tables with persian Alphabet now when I select some Item from ddlstate that contain these alphabet in persian "ی ،پ،... " it didn't show any Item in ddlcity but when I select item that didn't contain above alphabet it show item in ddlcity correctly why this happen?
I have an ASP.NET application that relies on the Random class to generate a pseudo-random string. It uses the following code (this is part of a larger piece of sample code provided by Google for apps SSO):
public static class SamlUtility
{
private static Random random = new Random();
private static char[] charMapping = { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p' };
public static string CreateId()
{
byte[] bytes = new byte[20]; // 160 bits
[Code]...
This normally works very well, but from time to time it starts generating a string of 'a'. From what I can tell from debugging, Random simply stops returning random numbers and instead fills bytes with the same value over and over. I've patched this by using a GUID instead, but I'm curious what happened in the original code. I'm assuming some form of entropy exhaustion, but I can't find any reference in the docs. Also, each time this has happened, performing iisreset restored the correct behavior.
I use this query for my table but it retrives the value for each row. It does not retrieve the size of the column name. I need to know the number of characters occupied in particular column. How do i get this value?
SELECT LEN(salary) AS MyLength FROM employee
How can I set a asp.net text box to accept up to 20 characters? I was trying the range validator and I set it up to 0 min value and 20 max value. The prolem is that if I write 12933, the range validator errors appear saying "only 20 characters allowed" so I think it is adding the values.
View 4 RepliesWhat would you all suggest a database with less number of tables and more number of columns or more number of tables with less number of columns. I am developing a web application using Visual stuio 2005 and Sql Server 2005
View 2 RepliesOn my current form I have it validating a Canadian Postal Address (xxx xxx). The space is optional but if the user does not use a space, then once the validation passes it will insert one.

View 3 RepliesI have a form that's used to submit emails. I'm not sure what the character limit should be for the body of the email. I'm thinking about setting it at 150. It's used to allow people to inquire about services provided by a small business. Should I allow more? Is this sufficient?

View 3 RepliesI am using mySQL. I have separate tables for several languages. When I display the Greek statements I seem to be limited to between 192 and 201 characters. That is not the problem with English, Danish, Dutch, Russian, or Farsi. I am using the same code for each with the only change being which table is opened. (In fact I just took the Dutch code and changed only the name of the table I'm opening to the Greek table and had the same problem.)The problem is that I've also double checked the statements in the table and they are complete, e.g., some have up to 255 characters.

View 3 Repliesit's a multiline TextBox the MaxLength property does not work. At the moment I only see the option to use a CustomValidator with checking TextBox1.Text.Length on server side and perhaps in addition some Javascript client side validation.But isn't there a simpler way to do this, using the standard ASP.NET validators (RegularExpressionValidator, RangeValidator, CompareValidator, etc.)
