Relative URLs Ch 7 (pp 240-243)

Great Sunday morning.

I understand the ~ and tried it on my website. It's in the MasterPages directory off the root of my site. It works as you can see at www.bdtcomp.com/iis6/ . This is how my header reads:

Code:

<h1 align="center"><img src="/images/bdtcompbanneraug12_08.jpg" alt="Freighter under Blue Water Bridge" width="740" height="175" /></h1>

Now when I change it to:

Code:

<h1 align="center"><img src="~/images/bdtcompbanneraug12_08.jpg" alt="Freighter under Blue Water Bridge" width="740" height="175" /></h1>

It doesn't work.

I changed the virtual path to / also.

I'm sure it's something simple on my part, but it has me baffled or is it because I have this image in the MasterPage?;-|

Hi there,

No, it's not because of the master page; the ~ concept works globally. Take a look at the How It Works section for the exercise you're referring to (at page 243, second paragraph) for an explanation of why this doesn't work and how to fix it. Hint: <img /> is a "plain HTML control"....

Cheers,

Imar

Here is how it looks in markup code in Frontend.master

Quote:

h1 align="center"><img src="~/images/bdtcompbanneraug12_08.jpg" alt="Freighter under Blue Water Bridge" width="740" height="175" runat="server" /></h1>

Thanks Imar, It's working. Here's the new URL from the Browser source. I'm convinced.

Code:

<h1 align="center"><img src="http://p2p.wrox.com/images/bdtcompbanneraug12_08.jpg" alt="Freighter under Blue Water Bridge" width="740" height="175" /></h1>

;-)

P.S. I am thinking that my <h1> tag is wasted here. I am going to replace it and put it in my headings, better for SEO!

Yes, you don't need the h1 one for the logo. You should have only one h1 per page, and it should describe the site or the page.

Yeah, I've got my work cut out for me, but 'find and replace' will help! But fortunately the Master page will make it easy on this website.

Well I have my site up at www.bdtcomp.com in .aspx files. I still have some bugs, thought I made a mess.

A word of caution to others, just make sure you save any web.config files on your servers if you upload your own. Then if you get those Server errors in web.config you can always put back the saved web.config.

I guess I will need to understand these files better and also check with my hosting company too for their requirements.
