View 4 RepliesReading And Saving An Image From Url?
Mar 29, 2010I would like to be able to read an image based on a url hosted elsewhere. To be clear, this is a legitimate service that is provided and they do allow caching of data, so I'm not trying to steal someone elses data.
So far I have the following code:
public static byte[] GetBytesFromUrl(string url)
{
byte[] bytes;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
WebResponse resp = req.GetResponse();
The area that I'm looking to improve on is the emboldened line. I think it would be better to read in say 1024k chunks until the file end. Can anyone help me out with the syntax for this?

View 1 RepliesVS 2008 - Saving GridView As Image
Aug 16, 2012I tried doing a search about saving a gridview as an image but have not found anything that works. I need to capture it or create one as an image to send to a mobile device for a dashboard. I know people tried capturing the grid like a screen shot but is there any other way? Sometimes the grid goes off screen. I assume i could create an image dynamically right? The tough part is setting the width of the columns and right/left justifying the data. Even if I could save an html table to an image also that would work.

Saving Resized Image Files To Server
Jul 13, 2011I am trying to save some resized images to the server. Why I get the following error on the vSmlImgFle.Save(vTmpDir.ToString & vFile.Name, ImageFormat.Jpeg) (in red below) line?
A generic error occurred in GDI+.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+.
And while we are on the subject of dealing with image files, is there a way to get the file format from the original file, rather than looking at the file extension to determine the file type:
If Ext = "JPG" then
Type = ImageFormat.Jpeg
Else if Ext = "JPG" then
Etc.
I thought that vImgFormat = vOrgImgFle.RawFormat might do it but that seems to return something completely different than ImageFormat.Jpeg.
Code:
Protected Function CopyScaleImages(ByVal FileSet As FileInfo())
Dim vTmpDir As New DirectoryInfo(Server.MapPath("~/SanInspPhotosTemp/"))
Dim vDir As New DirectoryInfo(Server.MapPath("~/SanInspPhotos/"))
Dim imgHght As Integer

Access To Path Denied When Saving An Image With 4.0 Project
Apr 26, 2010I have an existing application that was written in .NET 3.5. The piece of code in question is using the FileUpload control and its SaveAs method. Its worked perfectly for the past six months, but I've recently upgraded the project to .NET 4.0 and I'm now receiving an "Access to path (...) is denied" every time the method is called. It works fine locally in dev mode but fails on my prod server. I've upgraded the website to run under .NET 4.0 and I've made sure the account (Network Service) it runs under in the app pool has full control. Other than upgrading to .NET 4.0, nothing has changed for the project.
