SQL Server :: Stuck On Update Query / Identify That The First Letter In A Column In T1 Corresponds To One Letter In The Middle Of A String In A Column In T2 For Instance?

Nov 30, 2010

Heres the situation: I need update a column from my table (T1) from two other columns in a different table (T2).

My constraints are:

That I have to match the first 4 letters of a column in T2 to one column in T1 I have to identify that the first letter in a column in T1 corresponds to one letter in the middle of a string in a column in T2 For instance:

My Table (T1):

Order Type Combined
Place
0090 0001 YYXX 1YY
0091 1001 YYXX YYY
0092 1002 XXXX 2XX

Table 2 (T2):

Order Value
00900001YY XX
00911001YY XX
00921002XX XX

The Combined column in T1 is what i'm trying to complete. The T1.Place column contains the first character that I want to check for.

If it's a "1" then I want to make sure the 5th letter in T2.Order is a "0" If its a "Y" then I want to look for a "1001" If its a "2" then I want to make sure the 8th letter is a "2" in T2.Order
If all that matches then I was the last two letters in T2.Order + T2.Value to be combined and put into the appropiate spot in T1.Combined

Here's what I have:

[Code]....

I know it's a little complex, but i'm really stuck on it and any help would be greatly appreciated.

I think this is a little tricky problem, but I need to solve it somehow. I have a texbox in my asp.net page.

So for example: User types in "a" in a textbox then automactically names "aron" "asron" "amanda" in the list shows, and user can select one of those names.

Web Forms :: Capitalize First Letter And Every Letter After A Space Regular Expression Validator?

Jan 6, 2011

I want to maintain the consistency of my database, I want the first letter and every letter after a space to be capitalized before the record can be entered into the database. Currently my validator expression (^[A-Z]+[a-zA-Z]*[0-9]*[^f

v]*$) can achieve only the first capital letter and it can't check on the letter after every space, so what is the expression to achieve that?

C# Utility Class For To Make The First Letter Upper Case And Trim An Input String

Nov 23, 2010

This is my first class ever buildt (I am a real beginner) in C#. My aim is to "Sanitize a string". The class should do: trim an input make the first letter upper case. Is there a way to better code it? Would it make sense to use a PARAMETER for a method like: CapitalizeFirstLetterTrim(string x) when I initiate an object I need write a lot of code like below, any other way to make it shorter?

UserInputSanitizer myInput = new UserInputSanitizer();
myInput.Input = " ciao world";
string ouput = myInput.CapitalizeFirstLetterTrim();
Useful resource http://msdn.microsoft.com/en-us/library/bb311042.aspx
----------- CLASS
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace WebProject.Core.Utilities
{
public class UserInputSanitizer
{
// Backing variables
private string _input;
// Properties
public string Input
{
set { _input = value; }
}
private string _output;
// Backing variables
// Properties
public string Output
{
get { return _output; }
}
public string CapitalizeFirstLetterTrim()
{
// Trim
_input.Trim();
// Make First letter UpperCase and the rest levae lower case
_output = _input.Substring(0, 1).ToUpper() + _input.Substring(1);
return Output;
}
}

C# - Character Replacement In String?

Feb 23, 2011

I do need a working ASP.NET C# code to replace characters in a string.

My following code works fine but in case of input "a" it gives me an output as "678d", but in case of input "c" the output is correct as it is i.e. "8d"... Here it automatically replaces the rest values too. I can see the code is executing in a step by step process... This results me to get an overloaded output.

{
StringBuilder builder = new StringBuilder();
builder.Replace("a", "6b");
builder.Replace("b", "7c");
builder.Replace("c", "8d");
return builder.ToString();
}

Now, I do need to replace "a" as just "6b" and it should not load the rest values.

C# - Apply Client Side Validation On Fileupload Control To Check Filename Contain Special Character?

May 24, 2010

I am working on ASP.NET3.5 platform. I have used a file upload control and a asp button to upload a file. Whenever i try to upload a file which contain special characterlike (file#&%.txt) it show crash and give the messeage "Server Error in 'myapplication' Application." A potentially dangerous Request.Files value was detected from the client (filename="...New Text &#.txt"). Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.

Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Files value was detected from the client (filename="...New Text &#.txt"). Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. how can i prevent this crash using javascript at client side?

MVC :: Invalid Character In A Base-64 String?

Mar 22, 2010

I'm having trouble getting a form working with MVC2. As soon as I change the form element to use 'enctype="multipart/form-data"' I get errors when submitting it. The code I've got creating the form is as follows:

[Code]....

With several form text field and a file upload being the only fields. Nothing too complicated!The action method that handles the form submission is as follows:

[Code]....

It's nothing too complicated either. The code that I've commented out would have inserted the image into the database, but I commented it out to see if it was causing the problem, but it's not.The error I'm getting is as follows:

Server Error in '/' Application.

Invalid character in a Base-64 string.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.FormatException: Invalid character in a Base-64 string.Source Error: [Code]....

Stack Trace: [Code]....

Version Information: Microsoft .NET Framework Version:2.0.50727.4927; ASP.NET Version:2.0.50727.4927

Obviously something is going terribly wrong here, but I'm at a complete loss as to what it is. The form works fine if I get rid of the multipart bit in the form element, but then of course it doesn't upload the image. I also get the error regardless of whether I've actually selected an image to upload, so it's not the actual image causing the error.
