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.
My asp.net 2005 old application was working on windows 2003 server. I have used asp.net hashcode method to store user password in database. Now I shifted my asp.net 2005 application on windows 2008 R2 server. But my Password hashcode logic is not working due to 64bit windows 2008 server architecture & 64 bit IIS 7. I dont want to set IIS on 32bit mode.
So How can I check my 32bit user password on windows 2008 64bit server with 64 bit IIS without changing hashcode logic?
My environment is Windows 7 (64bit), with IIS7. I have a web application that I have hosted remotely, as well as running it locally. The problem is that, when running it locally, I would like to go to the app's address at [URL], but when I do this, the page seems to "Half" render, meaning only some images are shown, styles are not being applied, etc. It is very strange.
However, when running the exact same app in debug mode from Visual Studio (which provides a port, like so [URL]), then the App runs fine. I've looked through all IIS settings, and I am not spotting anything obvious that might be causing this. The default port should be 80 for the app. As far as I know I have left all IIS settings default for the most part, and I've installed every single Windows Feature related to IIS, from the control panel.
We Installed new application in our dedicated server. I struggle with an issue for the last few days. I get 404 no found in all WebResource.axd requests.
I have uninstall and install .net 2.0 - I have .net 3.5 installed as well. using webresource decrypter I found that many JS files, such as WebForms.js generate the erorr.
I check the iis handlers mapping for .axd
I disable http comp.
Need you for IIS setting on new Windows 2003 64 bit server we have installed the 32-bit application installer on new 64 bit server, application Insatallation and access is fine
View 1 RepliesApologies if this is is in the wrong place but I'm not sure where this issue fits. My issue deals with setting up an ASP.NET 64bit website on IIS6 (W2003 R2) so it could be a compiling problem or an IIS setup issue - I've read so much now I'm all tied up in knots.I have a web app which has been written on top of my company's custom framework, both have been compiled in .Net 2.0 with the "AnyCPU" option and run quite happily on my laptop within Visual Studio 2008 (on a Windows 7 Enterprise 64bit laptop). All of the code is managed code with the exception of 1 3rd party dll that I think is still 32bit.
Question 1: when running on my laptop in VS, is my web app running in 32bit or 64bit mode, given the OS is 64bit? I have both versions of .NET 2.0 installed.I have a new desktop that is to be our test server, and has been installed with Windows 2003 R2 and had IIS6 configured (same as the production environment). Again, both versions of .NET 2.0 are installed. When I copy my web app to the server and browse to the site, I get the dreaded "%1 is not a valid Win32 application", and sometimes (depending on what settings I've been playing with) "Service Unavailable" messages. If I register the .NET version to 32bit, and set the IIS 'Enable32bitAppOnWin64' to true, the app runs happliy the same as when on my laptop......but I don't want it to do that! I want to run IIS to run in 64bit mode with the 64bit .NET 2.0 Framework!Question 2: What does IIS see to make it think that my app is a Win32 app or am I interpreting that message wrong? Is the fact that I have 1 32bit dll in the in folder enough for IIS to say "32bit" and keel over?
My understanding of the "AnyCPU" option was that as long as the code is all managed code within the application, the bitness of the OS does not matter so I cannot understand why IIS6 cannot run the app in 64bit mode....and no, installing IIS7 is not an option.
I have created a windows service which runs round the clock
In every cycle it communicates with SQL data base and updates around 5000 employees records. Memory utilization is more.
My System configuration is about 3GHz CPU and 2GB Ram.
If I leave the machine for one full night memory utilization goes above 1GB. Service will be running but no work is done in the database.
I am working in Windows Mobile 5.0 application using C#. I want to get the status of phone memory e.g. Total memory, memory in use, free memory.
View 1 RepliesEnvironment.WorkingSet incorrectly reports the memory usage for a web site that runs on Windows 2003 Server.(OS Vers: Microsoft Windows NT 5.2.3790 Service Pack 2, .NET Vers: 2.0.50727.3607)
It reports memory as Working Set(Physical Mem.): 1952 MB (2047468061).
Same web site runs locally on Windows Vista with a Working Set(Physical Mem.): 49 MB (51924992).
I have limited access to the server and support is so limited.
so i have computed the total memory by traversing with VirtualQuery.
Total of pages with state: MEM_FREE is 1300 MB.
(I guess server have 4 GBs of RAM and PAE is not enabled, max user mode virtual address is 0x7fff0000.)
So, i know working set is not only about virtual memory. But, is it normal to have such a high working set while its very low on another machine?
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?
I need add a buttom to my aspx page.
My code is
byte[] buffer;
FileStream fs = new FileStream(@"C:info.pdf", FileMode.Open);

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.

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 =
"application/vnd.openxmlformats-officedocument.wordprocessingml.document"
Response.AddHeader("Content-Length",
MyData.Length.ToString())
Response.AddHeader("Content-Disposition",
"attachment; filename=" & dreader("file_name").ToString)
Response.BinaryWrite(MyData)
Response.Flush()
I am building an asp.net application, using II6 on windows server 2003 (vps hosting).
I am confronted with an error I didn't receive on my development machine (windows 7, iis 7.5, 64 bit).
When my wcf service tries launching my query running against a local sql server this is the error I receive:
Memory gates checking failed because the free memory (43732992 bytes) is less than 5% of total memory. As a result, the service will not be available for incoming requests. To resolve this, either reduce the load on the machine or adjust the value of minFreeMemoryPercentageToActivateService on the serviceHostingEnvironment config element.
I have both VS 2005 and 2008 installed on my machine. 2005 is fine. For 2008, literally any asp.net project I try to create gets this eror. I try stepping into the code, and the error occurs apparently before anything that I can trap is loaded. There is no information written to the event log. I have tried this with a "Hello World" webpage with nothing else going on. Seems unique to my Windows Server 2003 machine.
View 3 RepliesI am getting a weird error in asp.net while using leadtools imaging api. Here's the stack trace.

I am maintaining C# .NET code written by somebody else, I get following exception few times,Attempted to read or write protected memory. This is often an indication that other memory is corruptThe code structure where I get the above exception is somethign like this,- it is using ref variables in following sequence,Variable-1 and variable-2 are local variables in App1, - App1: func1() which passes these variables reference to func2(), - App1: func2() passes same variables reference via .net remoting to another application (App2).-App2: does the same passes same received reference to another call 2 times.- The execption is occured while returning from App2.
(App1:func1(ref Var1, ref Var2) --> App1:func2(ref Var1, ref Var2) <---App1 .net remoting to App2--> App2:func3(ref Var1, ref Var2)--> App2:func4(ref Var1, ref Var2)-->variables getting updated and function returned to original caller)
My doubts are ,1. Is passing reference variables in such chain is correct? will it cause such exeption? Does .net support ref variable call directly?
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 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 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 have a memory leak somewhere that I cant find. Every few days my server will crash, and just before that I log a ton of SQL errors stating that it is "out of memory".
I cant find it anywhere, all of my connections are being disposed like so:
[Code]....
Then I call the connection from my pages like so:[Code]....
That is all pretty straight forward. The connection is disposed because it is implementing the USING clause. I am opening the connection in my connection manager class, and not where it is being utilized?Or, could the problem be in the below method I am using to populate a SqlDataReader:[Code]....
Now, at first it appears as though this could be the problem because the Connection isn't part of a USING clause, however doesn't the 'Data.CommandBehavior.CloseConnection' pretty much do the same thing. This makes sure that the connection is closed when the reader is closed, right? Here is how I call that above reader from my login page code behind:[Code]....
So the DataReader will get closed even without the .Close() because it is in the USING, and the connection should get closed because I specified it in the ExecuteReader paramters right?
I have a memory issue on my websites and am trying to get to the bottom of it. I have downloaded the 14 day trial of ANTS Memory Profiler and have been playing with it to get a grip of what it's telling me. In the memory options on the timeline, I can see Bytes in All Heaps and Private Bytes etc but I am not sure which ones I should be focusing on to see where the memory spikes and doesn't go back down.I am profiling a ASP.NET website using ASP.NET 2.0.
