I am generating a pdf file to a MemoryStream, and then using Response.BinaryWrite to display that in the browser. But if a pdf reader is not installed, then I get an ugly error message.
Is there something I can do so that if no pdf reader is installed, I can display a friendly message or provide the option to save the file to the system?
I'm using localReport to print PDF (SQL REPORTVIEWER). It works fine on localhost. When I move the application to Production (64 bits windows 2008) it gives me an error. (see below)
I put the renderedbytes in a Session in USERCONTROL and I do window.open('Program1.aspx')...
In page load of Program1.aspx I try to retrieve the Session variable and process.... I think this statement cause the error "Response.BinaryWrite (...) etc".
It works on my local pc (Vista 32bits)...

I have binary data - it is png picture.
I use Response.BinaryWrite to display this picture.
Unfortunately it works only in Internet Explorer. In Firefox and Chrome it shows long text of strange symbols.
What's wrong with BinaryWrite? How to solve this?
I may not say to asp:Image to show this picture, I may not indicate ImageURL, becouse there's no URL. This picture is response from webrequest. And webrequest may not be indicated in URL because I set some parameters not in QueryString but in post data.

I need a click button after the code. How can I do this.
I am using a gridview to display (open or save) files that have been uploaded into a SQL 2005 server. I have a templatefield within the gridview that contains a linkbutton that does a postback to GetUploadedFile.aspx that then fires the response.binarywrite() code. The code seems to work fine and opens/saves the files correctly. But once this has completed and I try and click on another button on the page, instead of doing the appropriate action it re-fires the getuploadedfile.aspx binarywrite code and opens up the "Open/Save/Cancel" dialog again.

The dilaogbox that offers me to save the file shows incorrect chars if documentFileName has name not in ASCII format. What I'm supposed to do to have the file name displayed correctly in this dialogbox and to have this file opened under the same name in MS Word, Excel whatever else?
I have an MHTML file which has embedded images. The MHTML is generated on the server and then I will typically deliver the file using a BinaryWrite. I've also tried Server.Transfer, Response.Write after converting to ASCII and writing the file to disk and using a Response.WriteFile. In any of these cases the resulting file is not (it appears) treated as an mht file. For setting the image, I've tried Content-ID and Content-Location. The image URL shows up as cid:example1 when viewed in IE8. When opening up the file after saving to disk it shows up as mhtml:file://C:Documents and Settings enjynitoDesktopoutput634172401776447258.mht!cid:example1. Or while browsing with one of the methods that work you get [URL]
The Output.MimeType is message/rfc822. I've also tried application/octet-stream and multipart/related. Writing the file to disk and using a Response.Redirect works. Accessing the file with a direct URL works. Saving the file to disk and then opening the file works. It seems IE is assuming an HTML result to the request and not deciphering the new content type. But you can do things like this for dynamic style sheets, scripts, etc... so I don't really believe that. I couldn't see any glaring differences. I just tried and the BinaryWrite works fine in Opera. If I absolutely have to worry about writing to a temporary directory and then redirecting to the file I will. I was just hoping to avoid having to clean up the temporary files. Is what I want to do not possible? An example of writing the file is below.
if (response != null && response.Output != null)
{
Response.Clear();
Response.AddHeader("Content-Type", response.Output.MimeType);
Response.AddHeader("Content-Disposition", "attachment;filename=output" + DateTime.UtcNow.Ticks.ToString(CultureInfo.InvariantCulture) + "." + response.Output.Extension);
// Response.Write( System.Text.Encoding.ASCII.GetString(response.Output.Bytes));
Response.BinaryWrite(response.Output.Bytes);
//Response.Clear();
//Server.Transfer("/ISV/Forms/Test/output634172397522707394.mht");
//Response.Clear();
//Response.WriteFile( Server.MapPath("/ISV/Forms/Test/output634172397522707394.mht"));
Response.Flush();
Response.End();
I have a server page generating a PDF file on the fly. I am currently submitting it to the client with a binarywrite. I would like to submit it formatted with the following "Adobe" options:
pagemode=thumbs
view=Fit
Is there any way to do this with a BinaryWrite? Or any way to do this in Javascript?
My code reading a page from pdf file by PDFLib and sending it to client after putting watermark on the image. The problem is w3wp.exe posses is eating more memory in every request, so after using the program times the memory will be full. My Server system is windows xp 64bit.

We have been downloading Office 2003 documents stored in our database as images successfully using our ASP.NET 2.0 web portals. We recently started storing Office 2007 documents and though they upload without issue, the download and render does not work. The file opens with the error - "The file is corrupt and cannot be opened". It is only with Office 2007 files we see this. The web server supports the Office 2007 MIME types. We also apply the correct content-type when uploading a file to the database. Sample BinaryWrite code below. Is there something I am overlooking unique to Office 2007 files?
Dim MyData()
As
Byte
....
MyData = dreader("document")

Response.ContentType =

Response.AddHeader("Content-Length",
MyData.Length.ToString())
Response.AddHeader("Content-Disposition",
"attachment; filename=" & dreader("file_name").ToString)
Response.BinaryWrite(MyData)
Response.Flush()

First of all, quickly what exactly I want to achieve: translate particular exception into the HTTP 404 so the ASP.NET can handle it further. I am handling exceptions in the ASP.NET (MVC2) this way:
protected void Application_Error(object sender, EventArgs e) {
var err = Server.GetLastError();
if (err == null)
return;
err = err.GetBaseException();
var noObject = err as ObjectNotFoundException;
if (noObject != null)
HandleObjectNotFound();
var handled = noObject != null;
if (!handled)
Logger.Fatal("Unhandled exception has occured in application.", err);
}
private void HandleObjectNotFound() {
Server.ClearError();
Response.Clear();
// new HttpExcepton(404, "Not Found"); // Throw or not to throw?
Response.StatusCode = 404;
Response.StatusDescription = "Not Found";
Response.StatusDescription = "Not Found";
Response.Write("The whole HTML body explaining whata 404 is??");
}
The problem is that I cannot configure default customErrors to work with it. When it is on then it never redirects to the page specified in customErrors: <error statusCode="404" redirect="404.html"/>. I also tried to raise new HttpExcepton(404, "Not Found") from the handler but then the response code is 200 which I don't understand why. So the questions are:
1-What is the proper way of translating AnException into HTTP 404 response?
2- How does customErrors section work when handling exceptions in Application_Error?
3- Why throwing HttpException(404) renders (blank) page with success (200) status?
This might be a silly question, how do you usually response to errors? Response with one error at a time or Response with multiple errors at a time, in a list record
Example
Invalid Email Address format
Invalid Phone number format
Invalid Password .etc...
Invalid API credentials

Mailbox unavailable. The server response was: 5.7.1 Unable to relay
I'm moving applications from IIS6 to IIS7.5 (win 7 an win server 2008 r2), when 2 applications (with identity impersonate) try to get a file with response.writefile only from a UNC path i'll get "access denied". In IIS6 and Visual Studio Developer Web Server, same code works. I can save file with FilePath.SaveAs and get name and length with FileInfo, but not download. After 2 days of nightmares I have tried to change
Response.WriteFile(filePath)
to
Response.BinaryWrite(File.ReadAllBytes(filePath))
and now work. My question is: can I have a microsoft developer to sacrificate for my avenge?)
Hoping someone can point me to a solution, haven't been able to find one yet.
I'm using the standard way for send HttpWebRequest

As you can see from Fiddler/SOAPUI it does return the SOAP fault, however using HttpWebRequest i can't capture the response.
Returning 500 triggers my exception handling and Capturing the WebException doesn't expose the response.
Does anyone know how to capture this response xml in the case of 500 Internal Server Errors.

When the user tries to upload a file with a size more than 4 MB, the AsyncFileUpload control gives a Confirmation alert (with "OK"/"Cancel" button) with the following message "Server Response error: Maximum Request Lengh Exceeded". But when the User clicks the "OK" button a new window popups and shows the server error and on clicking the cancel button the AsyncFileUpload background color turns red. Here I am not sure why the control is showing a Confirmation alert instead of a simple alert message. Is it possible to change the Confirmation alert with the simple alert message? Basically I don't want the popup window to show the server error as it is happening currently. Also, is there a better way to handle the file size error and show apporiate error message to the users?
View 2 RepliesSome of my users are getting the following error
HTTP 502 Proxy Error - The size of the response header is too large. Contact your ISA server administrator. (12216) Internet Security and Acceleration Server
I am guessing it has to do with the size of hidden "__ViewState" tag in my ASP.NET pages.
I also realize that this is restriction imposed to by IT on the users end and I have no contol over it.
I disabled ViewState on all the controls in my ASP.NET pages. However, __ViewState is still generated very large (as always) to persist control-state (e.g. checkbox, radiobutton, etc.)
