I'm using to load website follow code
webContent.Navigate(new Uri(linkURL));
I want to cache all content and html tag, style, js in web to read offline.
I tried download html source, file css and js using Webclient and replace these file to html resource then save to file "index.htm" but not good.
Can you find the way to resolve this issue? thank you.
The only way to do this is to download ALL the relevant files (including those referenced inside the HTML. eg. images, css, js, etc.) and save them ALL to Isolated Storage with appropriate similar file and folder structures.
The important point is that you also need to update all the paths within the content so that they point to relative paths that match where files have been saved.
You can then load the HTML from IsolatedStorage.
This is potentially a lot of work. I'd recommend exploring other options if possible first. Also remember to manage the files stored in IsolatedStorage appropriately so you don't just keep adding files there indefinitely.

I have a .NET Server Control app that simply returns some HTML. I also need to embed several picture files into the assembly so that the HTML file can use them as its src= for each of them.
We will simply have a .HTML file that lives in the project as an embedded resource and the server control code will read this html and serve it up. Within THAT html, we will need to have all the picture src links (as well as CSS, js, etc) to point back to embedded resource files.
Does anyone know what code I would put in the HTML file for the pictures to make it point back to the embedded picture file?
I have to do this on a grand scale... hundreds of times. I really would like a programmatic approach to doing this so I can write a wrapper and never have to touch it again when we update the server control with new html, picture files, etc.
One might imagine a way to do this at compile time where I can loop through the embedded files with GetManifestResourceNames and then replace() the src links with the HTTP resource links I suppose?
Thank you for any guidance!
Hm, your question covers quite many aspects. Let me repeat to see if I got it: You have an assembly, with a raw HTML file in it. This file references some items, which are to be found within this same assembly, and you want to have them served to the client upon request as well.
One possible solution might be this.
Instead of a raw HTML file, use a templated one. Then, feed all available resource names as proper URL's into the templating engine, to replace the placeholders.You may want to look at DotLiquid for this.
Create a HTTP handler for each file type you want to serve. Inside the handler, you pull the item from the resources of the dll and serve them.
Alternatively, if those resources are rather small, you want to have a look into the data URI scheme, to save the extra requests and omit the handler. With this you could replace the placeholders with the data URI's directly, and serve a single HTML file with everything in it in the frist place.
Another choice is to have your .NET Server Control app check for optional GET arguments and return the image instead of the HTML.
Your original HTML request might be a simple:
GET netServerApp
Which returns the HTML with normal embedded links.
The HTML image links in the HTML might look like this:
<img src="netServerApp?src=Image1.svg">
or the like. Your server app would then return the appropriate image, instead of the HTML.
It means several round trips to get everything, but that is normal for HTML anyway.
How to go about uploading Multiple files(i have multiple files inside a folder) using file uploader by selecting target folder once in asp.net.if not using file uploader is there any other control for uploading file in asp.net?
You have several options to upload multiple files:
You can use a jQuery plugin, as described here.
You can use as many FileUpload controls as needed, as described here (videotutorial) and here.
But none that I can think of will allow you to select and entire "folder".
Hope it helps.
There is a good explanation of why this is not possible with standard .net controls on Velocity Reviews.
Here's more info on using Flash or Silverlight on StackOverflow. In summary, you can use something that allows multiple files to be uploaded (that the user manually selects) but you can't select a folder and have it upload each item in it, presumably because this breaks a law of the security gods.
You can use Radupload for multiple file upload.
i am using a iframe in my web page. I want to open a file c:\Dir\SubDir\xyz.doc inside a iframe.How to do this ? I checked out many sources ,all of them specified to give the source of the iframe to the path by adding the code.Its not working for me. Here is my code
iframe1.attributes["src"] ="c:\\Dir\SubDir\xyz.doc"
assuming you want to open a file on the client's computer, you would need to use a file URL, such as "file://c|/Dir/SubDir/xyz.doc". that said, it still may not work correctly for various reasons (probably primarily security-related).
if my assumption is wrong and you want to display a file on the server, you still need to use a URL and not a file path, meaning you'd have to have the file somewhere under the document root: "../Dir/SubDir/xyz.doc" for example.
then there is the strong likelihood that a .doc file will not render correctly on a webpage.
<iframe src="test.doc"></iframe>
above example is working in my environment, cause I put file inside my project folder and access that file from there..
you can not open any file out side of your project folder.... So please keep this in mind.
#jcomeau_ictx is right you cannot open .doc file in browser but yes it will ask you to save file, if you put in iframe..
I have a very huge amount of images (about 20K) that I don't want to be directly accessible by a user. Therefore I have a controller that streams a requested images back if the requesttoken is valid. I wonder now if I should store the images within a internal Resourcefile or just as content? I tried content before but you are able to access them from the browser if you know the folder and filename. The files don't change at runtime.
Thanks in advance for any hint on this!
You should use the App_Data folder for this. This folder is hidden from the outside so it is ideal for storing embedded databases or files as you want.

Let me explain better than what the question state. I dynamically generate a KML file from an aspx page and use routing to change the url so I can access myapp.com/mykml.kml and the download starts. I use Response.write() in the aspx page to send the data and it work flawlessly. But there is a zipped version for KML files which is KMZ and I am wondering if I can still use my aspx page to serve a KMZ instead of a KML. Since I do not use a file I cannot "zip" it. Is there a way to zip the stream and output it in the Response.Write()?
Yes, you can: ASP.NET - Create Google Earth .kmz files dynamically using in-memory streams and #ziplib
