Hi there,
I want to read a jpg-file from a url (f.e. http://someserverWhichIsNOTLocal/images/test.jpg), get the dimensions, resize it, save it to my local disk on the webserver as a gif-image and next show it on my own (mobile) pages. (Actually I'm reading some images from my normal website, which is on another machine, resize them, and show them on my mobile site ...).
The main problem lies in reading the image from a url ... can't seem to find how I should do that.
I'd like to be able to do something like :
thumb = System.Drawing. Image.FromFile( "http://someserverWhich IsNOTLocal/images/test.jpg")
But unfortunately that doesn't work.
Any ideas?
Thanks in advance.

The problem is that you're using a method which gets a file from a file
system, not an HTTP request, which is what you need to get an image from a
URL. What you need to do is to use a WebRequest to download the image and
then you can work with it. Here is a reference in the MSDN Library online
which should help: http://msdn.microsoft.com/library/de...nseclasses.asp

I've tried, but i can only read the data and place it on the screen, i

I'm writing a new control derived from UserControl.
I need to get an event when the control is done resizing.
I tried the Resize, SizeChanged, Move and the Layout events and I also tried
to override them. But they all invoked when the control is in the middle of
the resizing process.
I'm not using breakpoints, I'm using trace to see which one is invoked and
when.

Hi,
I am using an Access database (OLE Object) and storing Image as a bytes
after streaming. I am able to read it back as a stream and display it on the
browser using the following code:
Response.OutputStream.Write(fileData, 0, fileData.Length)
it displays on the browser as an image, but I want to display it in an Image
(web control image) so that I can manipulate its size.
How can I do this?

I want to read data from a file and assign it to a dynamically

approach has been to read the file twice, the first time to
determine its size, the second for the actual assignment. Is
there a more efficient way?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

For most users, this new feature is actually very convenient. If you want to control the update process,...
