what other way is there

[Guest]

hey all,

i'm using the following line of c# code:

bitmap.Save(Response.OutputStream, ImageFormat.Jpeg);

and i use this by saying

image.imageurl = picture.aspx?id= ...

my question is: is there anyway to directly assign the bitmap to the
imageUrl property without needing the aspx page to host it?

thanks,
rodchar

Hi,

I don;t understand what is your problem, the first line you are saving a
bitmap
and in the second one you are setting the image source of a image control in
a web page.

What one has to do with the other?

rodchar,

When you save a bitmap, you are saving it to the local file system.
That is, the file system on the server. When you set the imageurl property,
you need to set it to a URL that will deliver that file. There is no way to
directly assign the bitmap to the ImageUrl property. What you are doing
(generating the image in a separate referenced page) is what is required,
due to the nature of HTML (with the ability to hotlink).

Is there a block that you are hitting because of this?

i guess i was just wondering how the 3rd party tools did it because all you
have to do in those is drag a control out from the toolbox and bind to it.

Sorry about that last reply it probably didn't make any sense. The 3rd part
control i was referring to was the charting controls (pie, bar graphs). This
is just an FYI not a question. Thanks for your help.
