Colors have RGB value.you can compare that value.
Color A;
Color B;
if(A.ToArgb()=B.ToArgb())

There are RGB value.You can also compare it
Color A;
Color B;
if(A.R==B.R && A.G==B.G && A.B==B.B && A.A==B.A)
but it is the same A.ToArgb===B.ToArgb
Can you explain in details what you want to do?

See this example
I have made one method in which you can pass Bitmap object of image,current color of the image that you want to change as curColor and new color that you want to apply as newColor.
Now I am getting current color from image object using GetPixel Method of bitmap and apply new color using SetPixel Method.
this method returns bitmap object.after calling this method, call save method of bitmap so changes will apply.
Now this method will change image color that you want to change.
private Bitmap CreateGrayscale(System.Drawing.Image source, Color curColor,Color newColor)
{
Bitmap bmp = new Bitmap(source);
for (int y = 0; y < bmp.Height; y++)
{
for (int x = 0; x < bmp.Width; x++)
{
Color col = bmp.GetPixel(x, y);
if (col.A == curColor.A && col.R==curColor.R && col.G==curColor.G && col.B==curColor.B)
{
int r = (int)(newColor.R);
int g = (int)(newColor.G);
int b = (int)(newColor.B);
Color chgColor = Color.FromArgb(r, g, b);
bmp.SetPixel(x, y, chgColor);
}
}
}
return bmp;
}

Thanks Imrankhan.
But the problem is if we get all pixel of image and if we check A,R,B,G value of some perticular red portion only then also we will find that each pixel has different value of A,R,B,G for that red protion only. That is when you compare like...
if (col.A == curColor.A && col.R==curColor.R && col.G==curColor.G && col.B==curColor.B)
at that time we have to give some specific value of A,R,G,B and the portion which fit to this only will change to some other color. So if i want to change red portion whole red portion then how to change that whole red portion. Because in red portion only each pixel has diffrent value. so I need something which will replace these all realative red colors that is whole red portion not only single pixel.

You can create and write to file. But you can't store the file on any location. ASP.NET has access only in the website area.
vjainpee wrote: and the file should be in open mode automaticaly (user dont need to open the file )
What do you mean ? Why should you keep the file in open mode ? You know ASP.NET is multi threaded and you will end up with synchronization issues if you keep your file open.

Keep user type in the database. Say you have two types of users namely, "NormalUser" and "Administrator". Create two classes say "NormalUserPage" and "AdministratorPage" which inherits from System.Web.UI.Page . Override OnInit method and do the checking. In "NormalUserPage" check current user role belongs to normal user group and redirect him if not.
Create your ASPX pages and derive that page from the appropriate classes. I mean, if you want to allow a page for admin, derive that from "AdministratorPage". This will make coding more easy than checking in each page load.

Why not use the built in asp.net membership classes. .Net then takes care of all this for you. You simply type something like:
If User.IsInRole("administrators") then
'do something
elseif User.IsInRole("users") then
'do something else
end if
There is a database schema which will build the membership database for you, it can usually be found at C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regsql.exe.
The just look up on google how to implement form based authentication.
EDIT - sorry, meant to reply to the main thread

What error are u getting???
First of all have u deployed your app in IIS as a virtual directory? If yes then check your site properties in IIS, if u have a default document, add it to the list in IIS.
When you fail to plan, you are planning to fail.

Check whether ur server`s firewall is on. Switch it Off and try again. If u don`t wish to compromise on security, create a port in firewall to allow access.

Load the image into System.Drawing.Imaging.Image instance. It has a Save() method which allows to specify the image format.
|
|
|
|
|
System.Drawing.Image imgInFile = System.Drawing.Image.FromFile("C:\\caravan_sign.jpg");
imgInFile.Save("new", ImageFormat.Bmp);
This is how i m creating image as bitmap but i m not getting where it is created. I specify path like c:\\new but it is not taking so i just specify new but where this file created i m not getting.
