Web Forms :: Favicon Data Invalid - Getting Error On Building Report
Sep 14, 2010
I have an image that was a gif and saved as a favicon.ico. I get an error when I build the project that says data is invalid for this. What does this mean? Is it corrupted?

I'm doing a tutorial for error logging. It seems to be pretty basic. Everything works the way it should but I get an error I did not expect in my error log. The error says file not found for favicon.ico. From what I've read this is a file for the icon that would appear in the address bar, to the left of the url. I don't understand why I'm getting this error. I have no code that does this or references this file. It happens when I run the app in chrome and in firefox. Does the browser automatically look for this file to display to the left of the url? Is it automatically looking for this file as part of it's normal routine when loading a page?

I have created web method for "getting contacts".
My parameters are UNAME,PWD,VerticalID and Filter, now, there is no problem with my uname,pwd and verticalid, but my Filter have value of A,B,etc.in the sense just one character value.
But whenever I entered data,it returns this error:
"Specified Value has invalid CRLF Characters" this error belongs to Filter.
But when I entered ABCD it returns null because Filter is a string type and only one character value. But ASP.NET is not taking this one character value as string.

so I've set up the table as described.. (seems to be some directions missing with regards to, is identity? and is Primary Key? and what those values are and should be set to for name, description, and price durring table setup) So, ive tried to set the table up as directed and then go on to click DATA which allows me to fill in the table. I can fill in the table all the way accross but when i reach the end of the first row it says:
INVALID DATA your change could not be committed to the database. after you click OK you can fix the invalid entry or press to cancel your changes.

I have a website where I need to add a Favicon.ico. The site is written using ASP.NET 3.5 Web Forms with Routing. The issue is that the Favicon link always returns a page not found error. This is because the Routing does not know where the link for Favicon.ico should go to so it returns the Not Found page.
I have tried to add a StopRoutingHandler for the the favicon but none of them seem to work. Below are the ones I have tried so far:
routes.Add(new Route("MasterPages/{favicon}.ico", new StopRoutingHandler()));
routes.Add(new Route("{favicon}.ico", new StopRoutingHandler()));
routes.Add(new Route("favicon.ico", new StopRoutingHandler()));
routes.Add(new Route("favicon.ico/{*pathInfo}", new StopRoutingHandler()));
Does anyone know what I should be using? My favicon.ico links I have tried look like this:
<link rel="shortcut icon" href="/favicon.ico" type="image/x-icon" />
<link rel="icon" href="/favicon.ico" type="image/x-icon" />
And they are inside of my <html><head> tags.
Also, as one final note, I am not using MVC because if I was I could use this:
routes.IgnoreRoute("{*favicon}", new {favicon=@"(.*/)?favicon.ico(/.*)?"});
Unfortunately, IgnoreRoute does not work for Routing Web Forms though because it is not an MVC application.
