i did write it a long time ago...
Oops! In the field where it is being used it is very unlikely to happen (because the file names are specific to the customer site), but you are absolutely right - I'll fix it in the code next time I release an update - a quick stored proc will fix that!
Thanks for the head up...

When I do this, to avoid clashes of file and, I just use a guid as the file name on the disk. Simply store the original file name in your database along with the new name.

The brain part isn't an issue for me - mine was always feeble. The eyes are rapidly catching up.

I am using this code to set watermark for textbox but watermark now showing with no error.
here is the code:
private const uint ECM_FIRST = 0x1500;
private const uint EM_SETCUEBANNER = ECM_FIRST + 1;
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
private static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, uint wParam, [MarshalAs(UnmanagedType.LPWStr)] string lParam);
and in Form_Load:
SendMessage(txtLoginID.Handle, EM_SETCUEBANNER, 0, "login");
SendMessage(txtPassword.Handle, EM_SETCUEBANNER, 0, "login now");
SendMessage(txtPIN.Handle, EM_SETCUEBANNER, 0, "wow");
SendMessage(txtLoginID.Handle, EM_SETCUEBANNER, 0, "login");
SendMessage(txtPassword.Handle, EM_SETCUEBANNER, 0, "login now");
SendMessage(txtPIN.Handle, EM_SETCUEBANNER, 0, "wow");

If the watermark is showing without error then what is the problem?

he probably meant "not showing"

My watermark is not showing error AND not showing the watermark either!

You question does not say that now does it?
The code that you have posted works perfectly fine on my system.

Basically I am experimenting with Tuple for the first time and I am completely out of my element. I have no idea of how to correct the errors I am getting. Can someone please help.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Testing_Functions
{
class Program
{
public static Tuple<double, double> Test(Double Val1, Double Val2, Double Val3)
{
Double Test_Val = Val1 + Val2 + Val3;
Double Test_2 = 7;
return Tuple(Test_Val, Test_2);
}
static void Main(string[] args)
{
Double A = 1, B = 2, C = 3;
Tuple Result = Test(A,B,C);
Console.WriteLine("{0}", Result);
}
}
}

A tuple is a reference object, so you need to create one using the new keyword. Try this :-
public static Tuple<double, double> Test(Double Val1, Double Val2, Double Val3)
{
Double Test_Val = Val1 + Val2 + Val3;
Double Test_2 = 7;
return new Tuple<double, double>(Test_Val, Test_2);
}
static void Main(string[] args)
{
Double A = 1, B = 2, C = 3;
Tuple<double,double> Result = Test(A, B, C);
Console.WriteLine("{0} {1}", Result.Item1 , Result.Item2 );
Console.ReadLine();
}

I suppose that's true. IMO that looks a lot like it wouldn't have been necessary if Tuple had been a value type though, but it would have been.

To create a Tuple, use one of the generic constructors (or the static Tuple.Create() methods). I believe this is what you want to do:
var result = new Tuple<Double, Double, Double>(a, b, c);
return new Tuple<Double, Double>(test_val, test_2);

You have the answer to your question, this is just a comment regarding the casing of your parameters, variables etc.
There are some generally accepted rules for casing which makes code at a glance easier to read and understand. See here[^]. It is not normally recommended to use underscores, they don't add any clarity, and abbreviations are discouraged.
Taking the above into consideration your code would look like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace TestingFunctions
{
class Program
{
public static Tuple<double, double> Test(double value1, double value2, double value3)
{
double result1 = value1 + value2 + value3;
double result2 = 7;
return new Tuple(result1, result2);
}
static void Main(string[] args)
{
double a = 1, b = 2, c = 3;
Tuple result = Test(a, b, c);
Console.WriteLine("{0}", result);
}
}
}
This makes no difference to the execution of the code, it is just a personal (or company if you code professionaly) matter of style. There are also many differing opinions on some finer points!

DaveyM69, no personal attack intended, but I think it is generally unhelpful, and off-topic, to respond to a poster, struggling to get his, or her, head around a "best practice" technical strategy, with a "sermon" on variable-naming, and code-style: a topic on which there are many (widely debated) points of view.
Consider the "religious wars" over just use of indentation, and/or, the virtues of the location of a block-open curly brace, and block-close curly brace: K&R, where the block-start curly brace follows the final close-parens of the argument list (usually preceded by a space) vs. the practice of adding a line break after the end of the argument list, then the open-curly-brace, followed by another line-break, and then use of indentation.
Perhaps long ago, the very limited memory available in developer's machines made minimizing white-space desirable: but that is no longer the case.
The fact is that if you get employed in a working team with a substantial code-base, you will have to adopt to their notation and casing conventions.
And, some code transformations, such as KR style brace use <==> line-break-indent style, are easily done with very simple Regex expressions.
And, conventions, like use of braces, may have very different behaviors from language to language: example: JavaScript: variables declared inside {} are not locally-scoped and disposed; they are global.
For this reason, I voted your response a #1.
best, Bill

I believe some 'generally accepted' conventions should be followed as early as possible as code legibility and comprehension can be greatly increased for both the individual and anyone reviewing the code.
I did point out there were differing opinions too and also mentioned that companies have their own styles.
In my opinion it was far from a sermon; One sentence followed by a code example does not a sermon make.

You can return more than 2 value from function.
There are 2 way but I suggest you second one.
1. You can change your Method type to object[].
2. Create a class and its member can be what you need to return.
for example if you want to return 3 Double type value use these:
public class Result
{
public double FirstNumber { get; set; }
public double SecondNumber { get; set; }
public double ThirdNumber { get; set; }
}
Then in your function:
public static Result Do(params double[] numbers)
{
Result result = new Result();
result.FirstNumber = numbers[0] - numbers[1];
foreach (double number in numbers)
result.SecondNumber += number;
return result;
}

Why is your result class better than using Tuple?
Using params double[] may be a good idea for extensibility. If doing this however, it's important to check that numbers isn't null, and then check it's Length before using indexers otherwise some nasty exceptions may get thrown at some point.
