View 1 RepliesIn my Web page,I have a Div section with height=302PX and width=302PX.
In another page,I had a File Upload control. When we will upload the image,then the image will be displayed in that Div section.
1.When the image is large,it should be re-size and display in that particular Div section completely.
For Eg:The image size like 350PX*350PX and 1024PX*1024PX, it should be re-size to Div Section size has 302PX*302PX.
2.When the image is Small,it shouldn't be re-size and display in that particular Div section completely.
For Eg:The image size like 50PX*50PX,100PX*100PX and 302PX*302PX ,it shouldn't be re-size and display in that Div section.
For Eg:The image size like 15PX*15PX these will appear very small.But When uploading the file these images also should displayed completely with as it is in that Div section.But the image will displayed neatly.
3.If there are any tools for these type of conditions using ASP.Net.

View 1 RepliesI Have a generic handler that's serving member logo images:
http://site.com/logo.ashx?memberid=123
Now, I want to use it by caling a url like:
http://site.com/logo/john.jpg
So I would create a route for that (pattern: "logo/{username}.jpg"). But, my problem is - how do I retrieve {username} when inside ProcessRequest() of my generic handler? It's not a page, so I can't get Page.RouteData.Values.
I'm using the slideshow extender, however the images are not a standard size. The images are user supplied, and they are often displayed full size, so I can't standardize them. I need a way to resize them on the fly, and have them look good.
I've been working on this slide show off and on for some time. I've had many false starts, finding out after putting in quite a bit of time and work that there is just one thing or another that I cant't get to work. I'm hoping this ajax extender will be the answer. It won't be if I can't rezise the images.
what the extender can use as image sources? I know it can use an image on the hard drive, which is where my images are, but then I have the size problem. I tried using a webpage that uses a third party control to resizde the image, but that didn't work. I'm looking at this site: [URL] for resizing the images, can the output be used by the extender?
I am new to MongoDB and have a perfect place in mind to use it. However, it's only worth it if I can make the queries from JavaScript and return JSON.
