Is it possible to display thumbnails for the photos when uploading them to the server? Say, when user selects a photo on the local drive, a thumbnail is displayed on the page for preview and when user clicks on the "Upload" button, the photo will be sent to server.

im trying to build a gallery using C#.
Ii've made a Listview showing photos from database as thumbnails in a "kind of a film strip", including a pager.What i need is that when i click on a thumbnail inside the ListView, to show the large photo in a image control outside the listview. this should work using the selectedIndexChanged event,
I would like to know what the best method of uploading a batch of images/photos would be. Below are the steps that need to be implemented: Select Multiple images/photos from a directoryUpload original images to webserverGenerate thumbnailsUpload thumbnails to webserverAdd image and thumbnail details to a Database Does anyone know any vb.net script that will allow me to do this or will I have to code it from sratch?
View 2 RepliesI need to create a thumbnail solution in order to display pictures of products.
There can be more than 1 thumbnail per product and I need a way to enlarge the image as well. The thumbnails will be displayed in atleast 3 or 4 pages across the system and I need the ability to delete them as well. For version 2 of the software (knowing PM's it may be thrown into Version 1), I think I will need to be able to enhance this feature to allow movie clips so that's something I need to keep in mind. The images will be stored in the DB so I can sort the code to retrieve them but I'm originally a windows programmer and this is my first major ASP.NET project and also my first attempt at C#.
I am trying to display 4 photos per row
Now I am not sure how to evaluate this statement because it evalues true if I have 2 images the other two will mark up as an X
<img src="<%# DataBinder.Eval(Container.DataItem, "Column1")%>" visible="<%# (DataBinder.Eval(Container.DataItem, "Column1")!="") ? true:false %>"
This is always visible. All of them are evaluating to true.

View 3 RepliesThe more I think about it, the more confused I get. Is this even an ASP.NET question? Maybe it's a Silverlight question, or maybe it's an IIS question. Maybe it's a C/C++ question?!
I rent a server from a server farm. I also subscribe to a security service that streams, over the Internet, once every three seconds, via https, a series of JPG photos from four outdoor security cameras at a certain location.
I want to collect these photos on my rented server (server side). Keep in mind these are photos, not video, though after two weeks of streaming you can get around 50 GB of photos I am told, so I'll have to track storage consumed and delete the old ones, but that's a minor issue.
I researched how to capture streaming photos in ASP.NET and found nothing. I researched it in Silverlight and found a number of links for client side video chatting (a new feature supported by Silverlight 4) both multi-user and single-user, assuming they have web-cams attached to their client side PC. Not quite the same problem as what I have, since I don't care to attach any process to the four security cameras (the security company already wrote the software to do that, and is streaming it live). I just want to know how I can capture and store the streamed photos on my server.
while uploading the file on the local host it works fine.but the same coding does not work on the webserver. is there anything to do with the foldr read and write permissions.i m using the server.map for finding the path of the browsed file.
protected void btnLogin_Click(object sender, EventArgs e)
{
try
{
string fold = "images";
string Name = FileUpload1.FileName;
sring path = Server.MapPath("~" + "/" + fold + "/" + Name);

i hv not used any database for storing the path of the image.

I increased the default size in the web config to 195MB,and it's still not working. The following code depicts the size that I currently set in the web config.

View 17 RepliesI have googled around for a solution and it seems that a lot of posts are dealing with these kind of things. Unfortunatley none of them seem to help me. I'm trying to resize an image dynamically to create a thumbnail. I'm basically loading a current JPEG into an image object and using the following commands to create a new image:
[Code]....
I put the image which I get from the code next to a manual re-size which was made in Photoshop. You cannot even compare between the two, the dynamic one looks so blurry when you compare it to the one made in Photoshop. Is there a way around this? I imagine Microsoft found a solution for this by now. Otherwise I will have to upload manually 4-5 different versions to every image on my website which doesn't sound right to me.
I know we can show image thumbnails in a gridview...but what about thumbnails of word documents and pdf files?

I have an interesting challenge. My application uses a third party's services and one of the functions is to upload video files to Amazon S3. The current solution I've implemented uses a simple form with a POST action set to a URL on Amazon's system. The
issue I have is that because the form posts to Amazon, I have no way of doing any type validations before the user clicks to upload the file i.e. checking file type, file size, etc.
However, I really do NOT want to set up my logic so that the file is first uploaded to my server then to Amazon because these are huge files and we'll end up using costly bandwidth on both ends -- our server and Amazon S3.
P.S. To be perfectly honest, I'm not that pleased with the current solution where it's a simple HTML form with a simple post to Amazon. However, because Amazon is so picky about all the hidden fields in my asp.net page, I had to strip everything off the
page -- including form runat"server" because the minute I have this, I end up with a hidden field for ViewState -- even if I completely turn off ViewState. There's always something left as a hidden field and Amazon was generating an error because of this.
Ideally, I'd love to be able to do an HttpWebRequest in code behind so that I can have the functions of a web form back and do some pre-upload work but I'm not sure how to upload the file to a remote destination without putting the file on my server first.
I'm trying to figure out this error but I can't point out what's exactly causing this.Here is what's happening.User loggs in for a few hours and gets "Validation of viewstate MAC failed" Error after post back.I have set timeout in Web.config as follow.
<authentication mode="Forms">
<forms timeout="540" slidingExpiration="true" loginUrl="~/maintain/login.aspx" />
