.net - Options To Merge PDFs In A Web Site Or Web Service Environment?
Sep 3, 2010
I have multiple PDFs coming from a report generator and I want to merge them to a single document. The merging process must run in a web site or WCF web service environment (Framework 4.0, IIS 7.5). Is there a component, open source or commercial, to accomplish this?In my process I get the PDFs as streams. If I have the choice, I would prefer a merging method, working directly on these streams - without file representations.
We are trying to find a suitable tool that allows image manipulation (resize, merge etc.) server-side. what the state-of-the-art solution are at the moment?
I made an aspx site with .net 4.0 framework through visual studio and it worked perfectly in the development environment but when I upload it to the server and try to run it I get this error: Server Error in '/' Application. Runtime Error Does anyone have an idea on how to fix this?
I'm a bit new to the whole asp.net thing so this is probably a silly question, but here it goes: I have created a WCF Data service based based on a ADO.net Entity--it's very basic:
I am new to Web services and .NET. I have to authenticate a web service that is being accessed using http post. I tried putting a custom soap header and sending it to the service and checking the header in service but the header object is always null in the service.also if i put the user and password options in http headers how can i validate them on the server ? Client code:
I want to configure ASP.NET Website Project using WCF Service[NetTcp] (both in c#) for web-farm (for website) and NLB Load balancing (for service). I would like to configure following options for same.
NetTcpBinding.maxConcurrentCalls, NetTcpBinding.ListenBacklog and NetTcpBinding.MaxConnections
Note: During single machine configuration when I changed value of NetTcpBinding.ListenBacklog and NetTcpBinding.MaxConnections in WCF Service project to more that 10, which is default value. I got exception. When I changed this value in Website it was working fine. Due to this I had to keep in default configuration. Not sure why this is the case. Following reference gives idea how to configure in given environment but does not tell how to go about it. Ref: [URL] Update: Let me simplify a bit. Lets say I have following configuration.
2 IIS servers in Web Farm. 3 WCF Service Servers (NetTcp) in NLB Default config. for single instance. NetTcpBinding.ListenBacklog: 10 NetTcpBinding.MaxConnections: 10 NetTcpBinding.maxConcurrentCalls: 16
Now what will be my configuration setting in this environment. Will it be same as above or will be as follows.
where i need to understand the Raw XML Request and Response send thru when an web service API is called.We are using a Third part web service i.e. we have reference a third party wsdl file in our application and using its APIs defined.For Authentication purpose we are using web service extension in Framework 2.0
I don't know much about the .Net environment, so my first idea was to just write a console app that scans the folder for new content, and then emails alerts out. Then put the .exe as a scheduled task on the server, executing every few minutes. This seems pretty archaic to me though. Is there a more elegant way to do this for my website?

I have asp.net 2.0 site which is calling web services hosted on another server. When i have an xml file from where web service ip for eg. www.mysite/webservice1/myservice.asmx is given. When i call the same server from developer machine using local networkit works fine.But the same is when hosted remotely and from client end when services is called reading xml fiile from client machine it given a message 'remote server not connecting'.
I have a Default.aspx program that contains a Treeview with a SiteMapDataSource. I also have a web.sitemap loaded up with urls. When I run the deafult app I get the tree layout that matches the numbers of options but no text on any of the options to click.
I am looking for code that linearize PDFs file. that show page-by-page into the user's browser, so the user doesn't have to wait for the whole document to download before starting to view it.
I've been asked to implement a security requirement that we instruct browsers not to cache sensitive data. This is all fine for the ASPX content using the standard instructions:
However when I set these headers for PDF downloads, IE8 won't show the PDF (haven't tried other IE versions yet, kinda moot, I need it working on all of them, even IEfreaking6). Seems to work in firefox 4 beta, but I haven't double checked that it's definitely not caching it. Here is the abridged version of the code I'm using to serve the PDFs:
Response.Clear(); Response.ClearHeaders(); Response.ClearContent(); Response.Buffer = true; //This stops the PDFs from being viewed :( //Response.Expires = -1; //Response.Cache.SetCacheability(HttpCacheability.NoCache); //Response.Cache.SetNoStore(); Response.ContentType = mime; Response.AddHeader("Content-Disposition", disposition); Response.BinaryWrite(file); Response.End();
Where in the case of PDFs the mime type is set to: private const string mimeTypePDF = "application/pdf"; The disposition is set to: var disposition = String.Format("{0};filename="{1}"", SendInline ? "inline" : "attachment", Path.GetFileName(filename));
I'm going to play-around a bit more, maybe forcing them to download as mimetype "application/octet-stream" might work, but that would stop the nice open PDF's in a new browser window from working. Has anyone had any success with preventing IE from caching PDFs from the server side and successfully displaying them?
Just to give a clear example about what happens. In one scenario user's can select a bunch of reports from a list, these are compiled into a PDF and the PDF is shown in a new browser window. With the caching enabled the browser window opens, but remains resolutely blank.
I am currently working on a project where I need to secure access to downloadable files. The solution I want to implement is to have two buttons next to each document. One that says Editable and the other read-only (depending on the users permission they will see one of these or both). The editable will work normally with the browser dialogue opening to say open / save the document. That is the easy part. The read-only button needs to open the document without caching anything (in temporary internet files) on the client's machine for security reasons or give the ability to save it to their local machine.
The best Idea I have for this is to convert the document to HTML on the fly and then redirect the user to this page. We can then turn caching off on the site so the HTML isn't cached (I know they can then right-click and save the HTML or copy the text,etc.. but that is deemed acceptable). Does anyone have an alternative solution than this (or have an easy way this can be achieved)? I don't want to install Office on the web server or pay heavily for a third-party tool like Aspose.
I am creating a web app to basically allow the user to select multiple files, specifically pdfs that have already been created on a network path, and print whichever ones they want. Can someone point me to the best way to accomplish this? I have done a lot of searching, with no good results so far.
I have been presented with a problem which requires me to print PDF files from a server as part of an ASP.NET web service.
The problem is further complicated by the fact that the PDF files I have to print can ONLY be printed using Adobe Reader (they were created using Adobe LiveCycle and have some strange protection in them).
This piece of code seems to do the trick in the Visual Studio development web server, but doesn't do anything when the site's running in IIS. I'm assuming this is probably some sort of permissions issue!?
Dim starter As ProcessStartInfo Dim Prc As Process ' Pass File Path And Arguments starter = New ProcessStartInfo("c:program files...AcroRd32.exe", "/t ""test.pdf"" ""Printer""") starter.CreateNoWindow = True starter.RedirectStandardOutput = True starter.UseShellExecute = False ' Start Adobe Process Prc = New Process() Prc.StartInfo = starter Prc.Start()
I am interested in learning how to set up a secure report server with which I can publish individualized reports to my constituents. I know that banks and brokerage firms can do this, but I am not sure how it is done. I want to publish documents for an academic institution (grades, bills, transcripts, etc). I know some ASP.net and I am pretty fleuent in Crystal Reports. I am considering using a product like pdf-explode to disseminate reports via email, but I would really like to learn how to set up a secure site for my constituents and have them view the reports there.
Is it possible to have a web Service and Website in the same application. The web service would be [URL] and website [URL] Both would share the same code for logic and data access
I'm trying to consume a WSE enabled Web Service from an ASP.NET Web Site.I've installed WSE 3.0, used the config tool to add WSE info to my web.config and then done an Add Web Reference.I believe that the problem may be that this is a Web SITE, not a Web APPLICATION. As such, the proxy class is generated at runtime, perhaps not adding the WSE magic.I can access the proxy class from metadata, and it's of typeSystem.Web.Services.Protocols.SoapHttpClientProtocol, which as far as I can tell doesn't have any WSE functionality.I realize that this is all old technology, but I don't get to decide what the servers run :(
I want to pull down a feed (like twitter) and place in on a page using javascript (jquery). Ultimately, the "service" just needs to hand off JSON. I created a web service that allows me to do that, sort of. I don't know if using a stream reader is all that efficient and I was a little bothered by having to use what amounts to 2 evals on the clientside.
My question is twofold: is there a better method than using a web service and two, is there a problem with my implementation?
I am building a web service which uses some of an existing web site's methods. However, some classes and methods cannot be used (for example Redirect - which obivously throws an exception when not invoked from a web site's context).
Now I came to a section in code where
HttpContext.Current.Application.Get(keyNames.EncodedKey) Is used. (Where keyNames is a struct, and EncodedKey is a string.)but HttpContext.Current is null..
What is a valid substitution for HttpContext.Current.Application.Get?
I should mention that I've only checked this from a unit test, not the web service itself and following Darin's answer I realize that is the problem, so the question now is- how to mock HttpContext.Current(using moq)?
I have a website that seems to be Ok in Mozilla but when I access some pages in IE (mostly the ones where it has to contact a web service) the page hangs. If I refresh and then click the same button again, it seems to work fine 90% of the time. As mentioned, the same features work flawlessly in Mozilla.I am not really sure where I need to go to start debugging this but does anyone have any ideas on a cause?The website is hosted on my machine which is running on localhost using IIS7 on Vista and the web service is hosted in the same place. (So all it should need to do is contact itself). Its is an ASP.NET website running framework 2.0 (something)
