HI!

I have one quite short question. Does anybody know how instruct an update panel to update its context, without assigning a server side control(asp:Button) to do that.

Resizing images on upload

I need to do the following. Using ajax.net i create HttpRequest to the server, but with the difference that if server has no data for the client, the connection is not closed, but it is kept open. So when the data for the client arrives, the server can forward the data to the client. The data is just an id of the update panel that needs to update its content. So when the data arrives I need to instruct the specified update panel to update its content.

Hi
I currently have a form for people to fill in, with this they need to uplaod a profile picture of themselves. At the moment I have the following code which uploads the image, but i want to be able to resize the image to a certin size. Ive seen resizing help on the web, but most of these seem to be large/thumbnail codes and im getting a bit boggled!

Boolean fileOK = false;
            String path = Server.MapPath("~/uploadedconsultantimages/");
            if (UploadImage.HasFile)
            {
                String fileExtension =
                    System.IO.Path.GetExtension(UploadImage.FileName).ToLower();
                String[] allowedExtensions = 
                { ".gif", ".png", ".jpeg", ".jpg" };
                for (int i = 0; i < allowedExtensions.Length; i++)
                {
                    if (fileExtension == allowedExtensions[i])
                    {
                        fileOK = true;
                    }
                }
            }

            if (fileOK)
            {
                try
                {
                    UploadImage.PostedFile.SaveAs(path
                        + UploadImage.FileName);
                    FileUploaded.Text = "File uploaded!";
                }
                catch (Exception ex)
                {
                    FileUploaded.Text = "File could not be uploaded.";
                }
            }
            else
            {
                FileUploaded.Text = "Cannot accept files of this type.";
            }

Any help would be appreciated. I working in c# .net2 Smile | :)

Thanks

I haven't played around with the Upload stuff yet so not sure whether you can access the uploaded file in memory and resize it before saving it.

If not, then you simply need to use something like

Boolean fileOK = false;<br />
            String path = Server.MapPath("~/uploadedconsultantimages/");<br />
            if (UploadImage.HasFile)<br />
            {<br />
                String fileExtension =<br />
                    System.IO.Path.GetExtension(UploadImage.FileName).ToLower();<br />
                String[] allowedExtensions = <br />
                { ".gif", ".png", ".jpeg", ".jpg" };<br />
                for (int i = 0; i < allowedExtensions.Length; i++)<br />
                {<br />
                    if (fileExtension == allowedExtensions[i])<br />
                    {<br />
                        fileOK = true;<br />
                    }<br />
                }<br />
            }<br />
<br />
            if (fileOK)<br />
            {<br />
                try<br />
                {<br />
                    UploadImage.PostedFile.SaveAs(path<br />
                        + UploadImage.FileName);<br />
<br />
					Bitmap source = Bitmap.FromFile(path + UploadImage.FileName);<br />
					Bitmap result = new Bitmap(250,250);<br />
					using(Graphics g = Graphics.FromImage((Image)result);<br />
					g.DrawImage(source, 0, 0, 250, 250);<br />
					result.Dispose();<br />
					source.Dispose();<br />
					result.Save(path + UploadImage.FileName);<br />
<br />
                    FileUploaded.Text = "File uploaded!";<br />
                }<br />
                catch (Exception ex)<br />
                {<br />
                    FileUploaded.Text = "File could not be uploaded.";<br />
                }<br />
            }<br />
            else<br />
            {<br />
                FileUploaded.Text = "Cannot accept files of this type.";<br />
            }

This is untested, but basically "should" resize the uploaded image to 250x250.

Thanks, im still getting build errors though:

Error 1 Cannot implicitly convert type 'System.Drawing.Image' to 'System.Drawing.Bitmap'. An explicit conversion exists (are you missing a cast?)

Bitmap source = Bitmap.FromFile(path + UploadImage.FileName);

Thanks

Bitmap source = (Bitmap)Bitmap.FromFile(path + UploadImage.FileName); try this
Does it will help you ?
Bitmap.FromFile(path + UploadImage.FileName);
return type is Image Why you want to convert it into Bitmap
What you want to do ?

Thanks and Regards
