View 9 RepliesIn one of my ASP.NET page I have to send email to the users. I did this using System.Net.Mail namespace. The problem is if I want to send images I used the <img src=""/> to display them in my email. But now some of images are not hosted anywhere and I still want ti send the email with images. I want to embed them in my mail. Is there any way to do this in c#.

I'd like to create a class library project where embed resources like js, css and maybe image files. I would compile it and copy the dll into the bin folder of my web site to include the resources into my pages with GetWebResourceUrl.
I tried with an assembly that have no .cs files, but it doesn't seem to work, I can't see the namespace of the assembly in the web project.
I have a static HTML page complete with client-side scripts and css (both are included in the html). I was wondering if it would be possible to embed this HTML page into an ASPX page and have the ASPX page be able to respond to javascript events that are raised from within the static html document? Does asp.net provide a specific control for this or can I use a frame?
View 3 RepliesI've been trying to get image caching working for the last 8 hours and I keep the same problem time and time again, I'm trying to cache Images at the moment and then when thats succesful, apply this to cache my js and css files. I have at the moment Sql Dependancy caching working on my dynamic pages but the page still takes to long due to images not caching.
What I have tried is going to IIS7 Management and adding HTTP Response Header for the images folder and setting various things for the cache control.i dont care how long it caches it on the client or on the proxy servers i just would like it to check when the file was modified and compare it with the one in the client or proxy cache and if they are different then fetch the new image which has been ftp up. i could solve this by changing the image name but the thing is the image name is generated when they are ftp'd to the site by an application and the name is a direct reference to the product so i cant change the name each time, as it would mean making a lot of otherpages accross the board.
so What i would like, is to set and expiry date of lets say 32 days or more on the images and then check to see if they have changed by date modified or some other way of checking(Etags maybe) I'm not sure, if they have changed on the server then redownload and recache them, I tried using post-check and pre-check together but that just permantly cached them, so when i change the image the only way it would display the new image is to just hit F5.
In Brief, how can i Cache images, on the client machine/ proxy cache and recache them when the modified date of the file has changed.

View 2 RepliesI want to embed a excel file with macro in web page, and execute the macro when I click a button in the excel file.
I use iframe to do it as following ,
<IFRAME WIDTH="75%" HEIGHT="55%" NAME="fframe" SRC="Calculator.xls">
<FRAME WIDTH="75%" HEIGHT="55%" NAME="fframe" SRC="Calculator.xls">
<EMBED SRC="Calculator.xls" width=200 height=100>

how can i do it ? or if any other solution can do the same thing?
I have a web application that uses the master/child page layout you get by default (at least in a VS2010 web project). The Masterpage has a NavigationMenu, each item on that NavigationMenu has a NavigateUrl that looks like "~/Pages/MyPage.aspx". This automatically opens 'MyPage' in the Content of the Masterpage, so that the master page with menu and header etc stays visible.
Now, the client has a guestbook on her old website (I'm basically rebuilding her website, adding the ability for her to upload new content in her browser), and she wants to keep it. This guestbook is from a 'free guestbook' third party website, over which I have no control. It's simply a website in the form [URL] .... which shows the guestbook for a user 'Username'.
In her old website, I was using frames, so the menu on the left side was in a different frame, and I would simply open the third party website in the center frame. That would create the illusion that the guestbook was on her site, while it was actually a completely different website in a separate frame.
In my new website I'm no longer using frames, but the master/child layout as explained. Is it still possible to 'host' or 'embed' this third party website as a 'child' of the master page?
I tried just putting the url to the guestbook in the NavigateUrl of a NavigationMenu item, but that doesn't work, it just navigates to the third party website and doesn't embed it in any way.

I have some code that successfully traps an error 404 and diverts to an appropriate page. However, I have a problem with certain types of error. My code will trap the scenario where a user types, e.g.,
www.mysite.com/indecks.aspx where no such page exists. However, if the user types something along the lines
www.mysite.com/index.aspx/nonsensetext where index.aspx is a valid page, the page load event for index.aspx is triggered. However the page is rendered incorrectly because, I think, it is failing to find the images and CSS file associated with the page - perhaps because it is looking at the wrong path.
I expect that I can trap this by examining, for example, Request.URL.OriginalString and, if I detect garbage, I could re-direct to the same page "more cleanly" (i.e. without the junk on the end of the URL). However I'm a bit concerned that this is happening at all. Shouldn't this be treated as a 404 error?
My website use master page as template. All my other pages spread in different level folder. Master page will get images (which use related path - related to master page) from style sheet file which located in App_themds's sub folder. When application run,The page will lost all images if the content page did not located in the same level as Master page.

I have a page where I want to load a lot of images to. Say I have a page of like 50 images 2mb large each and I want them to be displayed on one page. Whats the best way to do that?
Basically what I'm doing right now is loading them from the server and displaying them in image tags. Problem is this crashes the browser. In chrome it will crash, in IE it will bog the computer down and lock it up. I think the browser is running out of memory or something.I'm wondering if I should be using a background worker or a different thread or something.. Is this possible with a web app?
I have an aspx page which I am pasting the code from. This page is a preview gallery which when I create a new gallery in my admin panel it auto updates to this page and places the text name I assign in the admin and assigns a page link which takes users to the actual gallery page for that preview... for instance I log in as admin and select manage free gallery.. enter the gallery name (for example" free preview") upload 8 or 9 images and a slideshow then hit submit. The gallery is then created and a link to that gallery is placed on my page for all free galleries. I want to not only have a link but an actual thumbnail image for these.. how would I do this given the code I am pasting below? I would also be willing to just eliminate the text link and go with a clickable thumbnail with a short description under it which actually would probably look better anyway. Pasted ASPX Code follows:

View 5 Repliesi would like to ask what is the best way to position and align images on an HTML web page.
I will have approximately 10 user-controls that each have a set of images on them laid out in a specific pattern, eg - an arc, a circle, straight line, some other sort of curve.
How i can achieve this using best practices?
Update: All the images will be the same size.
I am new in vb.net ... I am working on a project where users are able to post comments and also to be able to upload images. I am able to save the comments and also able to save the images to the database as a binary.
I am able to show the comments thru a listview as a user adds the comments, but how can i show the comments and the images. this would be similar like "Facebook"
In my web application I have a separate folder for Images and MasterPages and I am using forms authentication. Thus if I will not allow anonymous access for Images folder the login page will not be able to show any image.
guide me if this is what we should be doing or is there any other way to handle the scenario. Also, let me know is there any drawback of this technique.
