How To Create Arrays With Unknown Items And Dimensions
Feb 25, 2010
I'm taking input from a user and need to stick it into an array, the problem is, I don't know ahead of time how many dimensions the array will have and I also don't know how many items the user will want to stick in each dimension.The array will have a maximum number of dimensions of 4, but an unlimited number of items per dimension.I'm trying to create an unordered html list creator, so I need to know the number of items in each level of the list, and since (As far as I know) you can't create a multi dimensional array with a dynamic size

I have a DataTable that was built from dynamically created SQL, so I do not know the number of columns in the datatable.
How can I convert this datatable into an IList?
EDIT: I am then going to use this to send to a Telerik Grid on the page.

One of the reports I am creating has dynamic number of columns - a datatable gets returned from the stored procedure, the number of columns depend on the number of items defined in the database (one column for each item, other than some fixed columns). Is it possible for me to use RDLC report to generate a report in this case? All the calculations are already done int he report, I am looking at RDLC only for the sake of export to excel/pdf and repeating header/footer.

Given a URL to an image (and not the image itself), what's the most efficient of getting it's dimensions? I would like to change the height and width attributes in the image tag (<img>) if it is greater than 200x200. However, if it's smaller than that, then I'd like to keep the size as it is. (I'm using ASP.NET/C#)

I have a form that will accept and save a MP4 video file. I need to be able to get the dimensions of the video as well. This will be running on a server running ASP.NET 2.0 so any external libs must be able to be placed in the Bin folder as they can not be installed on the server.
how to get the information? If the same lib would let me transcode the video to flv that would be a huge bonus.
Update: The server is XP Service Pack 2 with .NET Framework (2,0,50727,0)

Im getting some images from a webpage at a specified url, i want to get their heights and widths. I'm using something like this:
Stream str = null;
HttpWebRequest wReq = (HttpWebRequest)WebRequest.Create(ImageUrl);
HttpWebResponse wRes = (HttpWebResponse)(wReq).GetResponse();
str = wRes.GetResponseStream();
var imageOrig = System.Drawing.Image.FromStream(str);
int height = imageOrig.Height;
int width = imageOrig.Width;
My main concern with this is that that the image file may actually be very large,Is there anything I can do? ie specify to only get images if they are less than 1mb?or is there a better alternative approach to getting the dimension of an image from a webpage?

Is it possible to specificy height and width dimensions of the ImageUrl attribute in a <asp:HyperLink> control? I tried setting the height and width attributes of the HyperLink control thinking the picture specified in the ImageUrl attribute of the HyperLink control would be resized to the dimensions of the height and width attributes but it wasn't.If I can't somehow resize the specified image for the HyperLink Im gonna have to scrap the control and do it the old fasioned way. By using a regular <asp:Image> control inside an <a href>.

What is the best way to create a hyperlink to a ListView's items? I'm trying to enable users to simply click on any of the ListView's items, which in turn has to effect that a detailed page for the specific item is opened in a new tab. Right, I got it working by using a Hyperlink component, which is a step closer to my goal.How to make the entire ListViewItem clickable.

I have a 2D array and i want to search that array. I thought Array.Find might help but it was helping only in 1D. I dont want to use for loop or foreach as that will take some time. So is there any other shortest method to find a value in a 2D array.

I am trying to bind a dynamic array of elements to a view model where there might be missing indexes in the html
e.g. with the view model
class FooViewModel
{
public List<BarViewModel> Bars { get; set; }
}
class BarViewModel
{
public string Something { get; set; }
}
and the html
<input type="text" name="Bars[1].Something" value="a" />
<input type="text" name="Bars[3].Something" value="b" />
<input type="text" name="Bars[6].Something" value="c" />
at the moment, bars will just be null. how could I get the model binder to ignore any missing elements? i.e. the above would bind to:
FooViewModel
{
Bars
{
BarViewModel { Something = "a" },
BarViewModel { Something = "b" },
BarViewModel { Something = "c" }
}
}
