C# - Convert Hexadecimal Color To RGB Color (24 Bit)?
Apr 4, 2011
How to convert and Hexadecimal Color in an equivalent RGB Color? Example: FF0000 to 255,0,0. My aim is to pass this color to the method FromArgb namespace System.Drawing FromArgb Method (Int32, Int32, Int32) (Alpha is implicit as opaque) At the moment I use this code to Clear and Image and apply a opaque flat color: System.Drawing.Graphics.Clear(System.Drawing.Color.Red)); This works fine with predefined color like "Red", "Black" and so on, but not obviously with a Custom more precise color.

I have a class (let's call it Car) that has a property of type System.Drawing.Color (Call it CarColor). I have a script service function that uses this Car class as a return value, which works just fine. I then have another script service function that takes a Car object as a parameter. I would like to change the color of the car in Javascript, but I am finding it difficult to do so without adding another parameter that takes in the color as a string and is then translated at the server. Are there any ideas on how to set the Color property of the Car object in Javascript and maintain it through to the server?

I am playing around with MVC 2.0 and have changed a few colors in the Site.css to suit my preferences but can't seem to get normal tab behavior for the menu to work.

Is there a way to easily hook this up or a hard way?

I do return this.File(filename, contentType, download name);
This action is called when user is clicked on a link and I have made $("a[rel='popup']").colorbox();
.So whenever a user clicks on the links It takes to the controller method and the file Shown in the colour box.
Now I am facing an issue it is like If a user is logged in to my site and open a page , where links are shown and the user goes away from his seat (ie session expires) Then he come back and clicks on the link .At that time my application breaks as there is no valid session.
So tried to return View("LogOn"); when session is null.
But as still it is not redirected to the I think it is because of the colorbox
I should be redirected to the log in page Even if I am taking a Color box ?

I'm trying to make a page, with a textbox, and a linkbutton. In the textbox you can enter any hex colour code you want, then you can click the linkbutton and the pages background will change to that colour. But I don't want the page to postback. I was trying this with themes, and then dynamically editing the CSS file. But neither has worked.
Is is possible to assign a background color to a MasterPage so the entire site has the same color? I'm using VS 2008 and have tried to do this with no success.
