Web Forms :: Response.WriteFile Adds Square Characters?

Mar 30, 2010

I've just installed VS 2010 RC and IIS7 with .NET framework 4.0 on a Windows 7 laptop (and I'm very new to this).

I'm trying to use Response.WriteFile to add a menu to an .aspx page, and it works but it also adds two square/unknown characters before the inserted text. Also, when I view the source of the displayed webpage in IE8, the source gets up to the point of the two squares, then shows an opening angle bracket (<) and then stops, although the rest of the webpage displays fine.

It doesn't matter whether the included file has any text in it or not, or whether it is an .html or .aspx file.

Response.Write doesn't have the problem.

(In FF and Opera, the inserted text is displayed as html code with a space (opera) or unknown character (FF) between each normal character. I'm not worried about those browsers as I'm developing soley for IE8)

Response.AddHeader("Content-Disposition", "attachment; filename=" + textFile);
Response.Flush();
Response.WriteFile(FilePath);
Response.End();
streamWriter2.WriteLine(CodeFileText);
streamWriter2.Close();
Response.AddHeader("Content-Disposition", "attachment; filename=" + textFile2);
Response.Flush();
Response.WriteFile(FilePath2);
Response.End();

But it downloads the first and stops.

It doesnot go for second one.

Aug 26, 2010

I've made a user control with several LinkButtons on it. On click of any of these buttons executing following code:

Response.ContentType = "Response.ContentType";
Response.AddHeader("Content-Disposition", "filename=" + CorrectFileName);
Response.WriteFile(filename);
Response.End();

And I have to problems with it:

1. after user click on one of the buttons another ones doesn't response

2. I need to execute some code after user received file (delete copy of it from the server)

I suppose I need to open another window and call SaveFile dialog from it. But how can exactly do this? I've found example code of opening window or starting SaveFile dialog but not two of them together and I can't figure out how to put them together...

.ashx Context.response.writefile - Use File On Remote Server?

Nov 27, 2010

I'm using an .ashx handler to retrieve an image file... It queries a local database, which retrieves the URL of an image which is hosted on Amazon S3.

But I can't use context.response.write(AmazonS3URL) because it returns the error '...is not a virtual path'.

Can context.response.write only return files that are on the local machine? Or is there another function to call remote files?

Web Forms :: Sitemap Ignores RouteExistingFiles / Adds Forward Slash

Oct 13, 2010

i have an up & running site based on asp.net 4 routing everything works perfectly except for one page the dynamic route for this page is [URL] i also have a physical folder in the site named admin at first i was getting a iis error when i tired to access this page. then i discovered RouteExistingFiles=true so now the page shows up whats odd though that the sitempappath is empty as well as another sitemap-based treeview on the page so i checked the page's sitemap.currentnode , which is also empty. why? so more research showed that [URL] is always redirected to [URL] (realize the foward slash at end!)

if i search the sitemap like this SiteMap.Provider.FindSiteMapNode("~/Admin") then it returns the node . but like this SiteMap.Provider.FindSiteMapNode("~/Admin/") [-with fwd slash] it return nothing so the question is: why is "~/admin" always redirected to "~/admin/" and how do i either stop it or make the sitemap ignore final fwd slashes?
