http://img404.imageshack.us/img404/5751/evar.jpg[^]
Above is the college's page where i do the same. but when i extract the html source of the page, i dont get table's data. but when i manuallly select the table and then view the page source,i can see that.
What i exactly wanna know is that how to that in dotnet? i mean how to get the source of the tabble.

Hi,
I am using this code to upload using Ajaxuploader:
using (Stream stream = item.OpenStream())
{
using (System.Drawing.Image img = System.Drawing.Image.FromStream(stream))
{
img.Save(Server.MapPath(String.Format("{0}/{1}/posts/{2}/{3}.png", Application["MemberMediaDirectory"], Session["volow_member_guid"], RouteData.Values["GUID"], image_guid)), ImageFormat.Png);
}
}
I want to know how can I resize the image before uploading to 906width X 360height?

You can't. submitting files to a website is voluntary, and the user has to choose which files to submit.
Websites that run in a browser on the client system run in a protective bubble, that is separated from the operating system. Sort of a sealed container.
You can resize the image after uploading by using system.drawing, measuring the size of the uploaded image, calculating the new height and width, and the new canvas size, and then creating a new blank canvas, and then overlay the original image over the canvas and save the new file.
Or you can write several programs in c++ to run on the client computer such as Linux, OSX, Windows, that will resize, and transmit the new bytestream to a webservice as a non-primitive, and then make the write to the disk drive.

Have a look at Plupload[^]. In a modern browser, it supports resizing PNG and JPEG files before uploading.

Hi,
Why I am getting the above error for this line:
TitleLabel.Text = data_table.Rows[0]["post_category_name"].ToString() + " - " + data_table.Rows[0]["member_channel_name"].ToString();
here is my stored procedure:
BEGIN
SELECT DISTINCT
post_category.post_category_guid,
post_category.post_category_name,
web_members.web_member_guid,
member_channels.member_channel_address,
member_channels.member_channel_name
FROM
post_category
INNER JOIN member_posts ON member_posts.member_post_category = post_category.post_category_id
INNER JOIN member_channels ON member_posts.member_channel_id = member_channels.member_channel_id
INNER JOIN web_members ON member_channels.web_member_id = web_members.web_member_id
WHERE member_channels.member_channel_address = param_web_address;
END

As per your code, it does not seem issue here. I'll advise you first run your Proc and see whether it is running and resturning data correclty.
Then you debug your code and check the datatable in immidiate window and see it in visualiser what columns are available in datatable.

So you get the error "Hi"
Never seen that error before. That's a new one for me.

Hello *,
I aked my question a few days ago on stack overflow but I'am not lucky with the one answer. Perhaps, someone can help me here.
My first controller method is:
[HttpGet]
public ActionResult Item()
In this method, I have some business logic like retrieve the user id with sql or watch out if a user has the permission to see some regions on the view or whatever.
I used bool variables in my viewbag and get these data with razor.
It's only one case..
Now, the user is going to fill data in a form, will make a post and then I call the same method, but with a [HttpPost()] flag (I saw it in many tutorials).
[HttpPost]
public ActionResult Item(FormCollection formCollection)
Ok, now I can collect the values out of the form and can work with them.
BUT if this function is ready, it gives as standard View() back and I can't made the business logic like in the Get() method or must I really copy/pase all these stuff or get it in a own function and call it two times?
Here is a link to my stack overflow question, perhaps you unterstand me better with that:

Hi Patric.
It seems that what you described as "some business logic" is some common processing that you want to fire in both GET and POST methods. In that case you can refactor it as separate method.
If that logic is valid only inside that one controller you can make private method that is called by both Item() methods - private controller methods are not mapped to MVC actions.
If it is more application wide you can also consider refactoring it out to some helper class.
BTW - copy/paste should be banned in any development environment
Regards,
Mariusz.

Guys;
I have published a website to a remote sever.
The get requests to page returns the correct HTML response, but request to javasript and and css files returns a blank response.
Help people,so poeple can help you.

With what you mention, I will start looking if the files are present at the path they should be. Relative paths as per deployment can be different then development environment. Using ResolveUrl helps.

No, Sir.
It was because the static content module wasn't installed.
Now, the question is; why isn't this feature checked by default when installing IIS7?
I mean what is the use of a web server that doesn't support static content requests?

Hi,
I have the following in Main.Master file:
ViewState["member_id"] = Convert.ToString(sql_reader["member_guid"]);
and in banner.ascx which is embedded in the Main.Master, I have the following:
<a href="<%# String.Format("{0}/{1}", Page.RouteData.Values["ADDRESS"], Eval("post_guid")) %>"><img src="<%# String.Format("{0}/{1}/posts/{2}/{3}.png", Application["MemberMediaDirectory"], ViewState["member_guid"], Eval("post_guid"), Eval("member_post_media_guid")) %>" alt="<%# Eval("member_post_media_title") %>" title="<%# Eval("member_post_media_title") %>" width="906px" height="360px" id="<%# Eval("member_post_media_id") %>"/></a>
but the ViewState["member_id"] is getting lost there and it's just blank! how can I fix it please?

Where are you assigning the view state at?
I think you have to assign the value in init in code behind, before page load.
If I remember correct, the webform elements load first, and then page.load fires in the page life cycle
Edit:
My mistake about the master page holding its own view state which is not shared. But I am correct about loaing the viewstate in page.init to hold its value during partial page post backs, and not page load

If you want to share some state across the entire page, try the Page.Items[^] collection.
