C# - Response.BinaryWrite Gives Error On Production?
Dec 6, 2010
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 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 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 ASP.NET web application that has the following settings in the web.config file:
(The actual names are different, obviously.) I am not a member of the real "Valid Site Users" group which is why I am given explicit access.I am able to access the site without a problem while developing and debugging locally; however, I get a 401 (Unauthorized Access) error when I deploy the site to a server. The only way to gain access is to remove the <deny> element from the configuration, which is not an acceptable option.I'm certain the solution is something simple and I am just overlooking
I run a asp.net 4.0 website. (I did the porting from version 3.5 to 4.0)I receive the following error :ASP.NET AJAX client-side framework failed to loadn a page where I set scriptmanager EnableCdn="true" and there is a microsoft ajax extension Timer on the page.
I receive the error only on the production server.
am using Slideshow ajaxcontrol and its works perfect in the VS2008 in the local system, where as when I move to server (production) it is not working, I was getting different issues, I solved few by refering some forums, where as still it is not wroking or no error can any one help me here.Here is the URL of production: http://126.96.36.199/$sitepreview/focusedreader.com/demo/Default.aspxCode of Default.aspx is
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-
When I try to run my ASP.NET app from my development environment I get the following error message: Compiler Error Message: CS1502: The best overloaded method match for 'mmars.Printing.printFunctions.SetPrintSummaryProperties(mmars.contextInfo, ref mmars.Printing.printObjSummary)' has some invalid arguments.
When I publish and run on our production server I don't get this error.It seems to compile fine when I build from the build menu (in fact if I change the second argument of the bolded function call below, i get a compiler error in visual studio), but now i've suddenly started getting this error message at runtime. So another question I have in addition to getting rid of the error is why is the .NET development server even trying to do JIT compilation on my project if it is already compiled into a DLL?
Printing.printObjSummary myPrintObj = new Printing.printObjSummary(); Printing.printFunctions.SetPrintSummaryProperties(ci, ref myPrintObj); printObjects.Add(myPrintObj);
Also, though there are no warnings at compile-time, when I get redirected to the page with that first compilation error there are many warnings like the following:
Warning: CS0436: The type 'mmars.MMARSSummaryDataItem' in 'c:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files oot3dad423c40569048App_Code.b0rgpkzr.4.cs' conflicts with the imported type 'mmars.MMARSSummaryDataItem' in 'c:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files oot3dad423c40569048assemblydl37179c19a345f948c_ece7ca01mmars.DLL'. Using the type defined in 'c:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files oot3dad423c40569048App_Code.b0rgpkzr.4.cs'.
What's the deal with that? Is the webserver complaining about name conflicts in the source file and dll resulting from the source file?
But now if error occurs the server will display his default error page for 404 page.Now i want to display my customised error page.Please tell me the entire steps to implement this in asp.net mvc 2.0.i,e is there any coding i have to write in then controllers or in the global.asax.
We have had some problems with using a unmanaged DLL file written in Delphi. (Unable to load dll - not found...)The following code solved the problem on my local machine:
1) The elusive DLL is copied to the ASP.NET temporary files folder2) To check this we get a list of files from that folder.3) The needed function is called with DLL-import.1 & 2 works perfectly - both run directly from Visual Studio 2010 and when uploaded to a webhotel3 works perfectly local, but causes the remote host to think a little and then return a HTTP 503 Service Unaviable error for the next few minutes...
I am dynamically generating script code to return transaction data to Google Analytics using their ecommerce script. The code that generates the script is fully tested and functional on my development machine and when I view the page code the script, along with any values that were passed to it, can be seen above the </form> tag. Happy days, or so I thought. For some reason the code is not being generated when I test it in a live, hosted environment. I cant figure out why this is the case as the code is quite simple. I simply generate the script code and register it on the client side (see code below)
//Capture the transaction data for analytics ecommerce tracking //Generate the necessary script code string strAnalyticsEcommerceScript = Analytics_Ecommerce_Script_Creator(); //Register the script on the page Page.ClientScript.RegisterStartupScript(this.GetType(), "AnalyticsScript", strAnalyticsEcommerceScript);
The page in question is called "Order-Successfull" and is where customers are sent to when they have succesfully payed for an order. On this page:
-The order is added to the orders database table - The customer is emailed an order confirmation email - The google analytics script is generated and registered
The Sequence is as follows:
Whats really interesting is that if I move the Analytics script creator code before the code that sends the emails, the script is generated and can be seen when I view the page code. If I do this, however, the emails do not get sent. If I lay the code out as per the code I have inserted in this post, the emails get sent but the script code is not placed on the page.. The code to that actually sends the emails is quite standard:
I have an application that uploads an Excel .xls file to the file system, opens the file with an oledbconnection object using the .open() method on the object instance. The upload and writing of the file to the file system works fine but I get an error when trying to open the file on our production server only. The application works fine on two other servers (development and testing servers).
The exception comes on production server at connection.Open() some times, when I reset the asp.net worker process it started to work but after some hours/days It occurs again. how can I fix this issue which comes in production some times but very irritating, or there is some other work around.
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.
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.
This is me code:
Also I tried useing: Response.Buffer = False but no usefulness.
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?
