• Is Your Desktop Printer More Expensive Than Printing Services?

  - by Eric Z Goodnight

  While many users see desktop printers as the best way to print photos, compared to cheap printing services, they may be more expensive. In this simple How-To, learn how to compare the cost per print to commercial options. Readers may not think of desktop printers as “convenient,” however manufacturers are largely selling the convenience of being able to print at home. Many commercial printers may offer services that are cheaper, even at small quantities.

• ERP/CRM Systems. Desktop Based ? Web based?

  - by Parhs

  Hello guys... I have seen 2-3 ERPs in action. I am wondering what is better. Desktop based application or webbased displayed on a browser. My first expirience was with a web based ERP when i was 14 years old.. It was web based and terribly slow... For most simple task you had to do lots of clicks... no keyboard support ..... Pages took ages to load. Last year i worked for migrating to a newer computer some old terminal based cobol application. The computer that worked till today and still has no problem was from 1993. The user interface ofcourse was textbased.. The speed that guys placed orders was amazing! just typing the name of the customer , then 5-10 keys to add a product to order.... Comparing to this ERP the page for placing orders Link (click sales orders) seems terribly slow to add a product... No keyboard shortcut works to save what you added and generally i believe you need 4 times more time to place an order compared to the text interface... Having to use both mouse and keyboard for this task is BAD and sadistic... So how can tek heck these people ever use a system like that ??? So in the long run desktop application seems the only way... Ofcourse browsers support shortcuts but the way to overide the defaults that browsers uses isnt cross compatible... That is a hudge problem. Finnaly, if we MUST/forced use cloud in near future what about keyboard shortcuts?? I feel confused... I have seen converters of desktop applications to browser applications but are SLOW as hell... The question is what about user friendliness?What kind of application would you use?

• How can I remove unmounted SD Card icons from my desktop?

  - by user75286

  I have been using some audio utilities in Ubuntu 11.10 to tweak .mp3 files on my phone (Motorola Photon 4G). I connect via USB... both my phone and the internal SD card are mounted as two separate drives. The SD card has an unusual drive name with some odd characters. When I'm finished, I unmount my phone (or "safely remove drive"), but the SD card can't be unmounted. I've mounted and unmounted my phone on 4 occasions now, and there are now 4 SD card drive icons that I can't remove from the desktop. I tried using the gconf-editor/apps/nautilus/desktop trick to make drives invisible and it's not working. Right-clicking on the icons and selecting "unmount" produced the following error message; (I can't type the unusual drive name characters... replaced with xxx) Unable to unmount xxx umount: /media/xxx is not mounted (according to mtab) How can I remove the unwanted icons from the desktop and is there a method for avoiding this problem in the future? Thanks!

• Designing a frontend/backend architecture

  - by wrp

  What are some good information sources on designing programs with a client/server architecture? This is for development of a desktop application, not a Web service. The only books I have found on client/server apps deal with the case of a thin client connecting to a remote database. Two good examples of what I mean are Mathematica and SuperCollider. I'm looking for platform- and language-agnostic discussion of the issues in developing a frontend/backend system. Especially useful topics would be allocation of responsibilities and options for message passing.

• Ask about the copyright of develop destop application based on web application

  - by Nano HE

  Hi, I googled and found some web online caculators (such as BodyFatCalculator & CaloricCalculator). I plan to develop the desktop Caculators in C#(WPF & .net 3.5). But I would test the online function and build my application module (I think some body properties not suit for asian people, maybe I still need do more research.). But now I must study others web app before my destop app design. Could I develop my app without the web application owner's permission? Thank you.

• What is the best way to manage application screens in SWT?

  - by parxier

  I'm creating a standalone SWT desktop application that has around 10 different screens (few wizards, help, forms, etc). Some elements on screen don't change at all (like header, background, etc) and there is a working area that changes depending on what is clicked, etc. What is the best way to manage application screens? Do I need to create all screen at startup and then show/hide them depending on what is clicked? Or do I need to create those screens dynamically? Also, I couldn't find any way to show/hide a Composite, do I need to dispose it and then create again? What is the best practice? I'm new to SWT developing outside of Eclipse so any help would be beneficial.

• Is there such a thing as a dektop application event aggregator, similar to that used in Prism?

  - by brownj

  The event aggregator in Prism is great, and allows loosely coupled communication between modules within a composite application. Does such a thing exist that allows the same thing to happen between standalone applications running on a user's desktop? I could imagine developing a solution that uses WCF with TCP binding and running inside Windows Process Activation Service. Client applications could subscribe or publish events to this service as required and it would ensure all other listeners get notified of events as appropriate. Using TCP would enable event messages to be pushed out to clients without the need for polling, ensuring messages are delivered very quickly. I can't help but think though that such a thing would already exist... Is anyone aware of something like this, or have any advice on how it may be best implemented?

• Which is the best API/Library to use when accessing a WebCam in .Net?

  - by Doctor Jones

  Which is the best API to use when accessing a WebCam in .Net? (I know they can be webcam specific, I am willing to buy a new webcam if it means better results). I want to write a desktop application that will take video from a webcam and store it in MPEG4 formats (DivX, Xvid, etc...). I would also like to access bitmap stills from the device so I can do image comparison between frames. I have tried various libraries, and none have really been a great fit (some have performance issues (very inconsistent framerates), some have image quality limitations, some just crash out for seemingly no reason. I want to get high quality video (as high as I can get) and a decent framerate. My webcam is more than up to the job and I was hoping that there would be a nice Managed .Net library around that would help my cause. Are webcam APIs all just incredibly bad?

• Which language + framework should I use for building standalone clients for my PHP webapp?

  - by Jagira

  Hello, I have a PHP web application which basically maintains a set of user profiles and their records. My users are using the app via browser. I am planning to build a standalone desktop client/app for WINDOWS OS, in which a user can login, retrieve and modify the records. Which language + framework will be simple, fast and lightweight to use? I can think of the following options: Microsoft Visual Basic - simplest? Microsoft Visual C++ Python PHP + bambalam compiler Are there any other options? And which of these is better?

• WPF Books in 2010

  - by notJim

  I'm looking to learn WPF, and I'd like to get a book to help in the process. Most of the popular questions on SO regarding actual books are from 2008, and I wanted to see if recommendations for books had changed at all. WPF Unleashed, which seems to be the most popular recommendation, was published in 2006, which is quite a while ago, with the lightening-quick pace that Microsoft has been following with .NET. Does this book still work? For some background, I'm a web developer (using MVC, so MVVM makes sense to me conceptually), looking to make the jump to desktop development. I did C# a while ago, but I'll be picking up a separate C# book to get up to speed on that. I am not interested in Silverlight. I am not necessarily interested in flashy UIs right now, as I'm working on business software but what I am interested in is good, clean, intuitive user interfaces.

• Best practice for autoupdates

  - by ravi

  For desktop based applications, what are best practices to perform auto updates? Currently, we download all files, then copy and register (if com dll) to their respective directories. I looked at Google Chrome update method. It seems that it first downloads a zipped file into a directory, and then unzips all the files. Also, they have a setup application which seems to be used to do the update. Additionally, they create a directory mapped to update version like 1.0.154.43, but they keep the old version's directory.

• How can I work efficiently on a desktop sharing workflow?

  - by OSdave

  I am a freelance Magento developer, based in Spain. One of my clients is a Germany based web development company and they're asking me something I think it's impossible. OK, maybe not impossible but definitely not a preferred way of doing things. One of their clients has a Magento Entreprise installation, which is the paid (and I think proprietary) version of Magento. Their client has forbidden them to download the files from his server. My client is asking me now to study one particular module of the application in order to interact with it from a custom module I'll have to develop. As they have a read-only ssh access to their client's server, they came up with this solution: Set up a desktop/screen sharing session between one of their developer's station and mine, alongsides with a skype conversation. Their idea is that I'll say to the developer: show me file foo.php The developer will then open this foo.php file in his IDE. I'll have then to ask him to show me the bar method, the parent class, etc... Remember that it's a read-only session, so forget about putting a Zend_Debug::log() anywhere, and don't even think about a xDebug breakpoint (they don't use any kind of debugger, sic). Their client has also forbidden them to use any version control system... My first reaction when they explained to me this was (and I actually did say it outloud to them): Well, find another client. but they took it as a joke from me. I understand that in a business point of view rejecting a client is not a good practice, but I think that the condition of this assignment make it impossible to complete. At least according to my workflow. I mean, the way I work or learn a new framework/program is: download all files and copy of db on my pc create a git repository and a branch run the application locally use breakpoints use Zend_Debug::log() write the code and tests commit to git repo upload to (test/staging first if there is one, production if not) server I have agreed to try the desktop sharing session, although I think it will be a waste of time. On one hand I don't mind, they pay me for that time, but I know me and I don't like the sensation of loosing my time. On the other hand, I have other clients for whom I can work according to my workflow. I am about to say to them that I cannot (don't want to) do it. Well, I'll first try this desktop sharing session: maybe I'm wrong and it can actually work. But I like to consider myself as a professional, and I know that I don't know everything. So I try to keep an open mind and I am always willing to learn new stuff. So my questions are: Can this desktop-sharing workflow work? What should be done in order to take the most of it? Taking into account all the obstacles (geographic locations, no local, no git), is there another way for me to work on that project?

• Is LaTeX worth learning today?

  - by Ender

  I know that LaTeX is big in the world of academia, and was probably a big name in desktop publishing before the glory days of WordPerfect and Microsoft Office but as a Windows user that is interested in the power of LaTeX and the general smoothness of a LaTeX generated page is it really worth learning? In a couple of months I'll be starting my final year in Computer Science and LaTeX has been bounced around the campus by many of the Linux geeks. In reality, is there any need to use it today? What will I actually gain from it and will I enjoy using it? Finally, how does one use LaTeX on a Windows machine? What software do I really need? I've read a couple of guides but many of them seem like overkill. Please help break a LaTeX newbie into the world of professional academic publishing! EDIT: I've toyed with LaTeX for a while, and have even learned that it's pronounced "lay-tech", not "lay-tecks". I'll agree once again with the accepted answer in saying that MiKTeX is the best solution for Windows users.

• Building Cross Platform app - recommendation

  - by Ben

  Hi, I need to build a fairly simple app but it needs to work on both PC and Mac. It also needs to be redistributable on a disc or usb drive as a standalone desktop app. Initially I thought AIR would be perfect for this (it ticks all the API requirements), but the difficulty is making it distributable, as the app would require the AIR runtime to be installed to run. I came across Shu Player as an option as it seems to be able to package the AIR runtime with the app and do a (silent?) install. However this seems to break the T&C from Adobe (as outlined here) so I'm not sure about the legality. Another option could be Zinc but I haven't tested it so I'm not sure how well it'll fit the bill. What would you recommend or suggest I check out? Any suggestion much appreciated EDIT: There's a few more discussions on mono usage (though no real conclusion): Here and Here EDIT2: Titanium could also fit the bill maybe, will check it out. Any more comments from anyone? Ben

• What off-the-shelf licensing system will meet my needs?

  - by Anders Pedersen

  I'm looking for an off-the-shelf license system for desktop software. After some research on the net -- and of course here on StackOverflow -- I haven't found one the suits our needs. I have a couple of must-have features and some would-be-nice features: Must have: Encrypted unlock key Possibility to automate the unlock key generation on my website User info in key so that I can show name and company in an about box and perhaps in reports Nice to have: License managing tools Online activation Nice upgrade possibilities to a version with concurrent license model and subscription model I have looked at Manco, but I find them difficult to work with and the documentation is minimal. Further, I couldn't get the name in the key. Also, the automatic generation of a key on my website has to be done with an application web service, but I would rather program against a DLL. Next I looked at xheo. It is easier to use and the documentation is better, but the price is substantially higher and here you can only get the user name in the license file that you then have to provide together with the unlock key. Could anyone share their experiences on what you are using and how it is working for you?

• Poll multiple desktops/servers on a network remotely to determine the IP Type: Static or DHCP

  - by Charles Laird

  Had a gentleman answer 90% of my original question, which is to say I now have the ability to poll a device that I am running the below script on. The end goal is to obtain IP type: Static or DHCP on all desktop/servers on a network I support. I have the list of servers that I will input in a batch file, just looking for the code to actually poll the other devices on the network from one location. Output to be viewed: Device name: IP Address: MAC Address: Type: Marvell Yukon 88E8001/8003/8010 PCI Gigabit Ethernet Controller NULL 00:00:F3:44:C6:00 DHCP Generic Marvell Yukon 88E8056 based Ethernet Controller 192.168.1.102 00:00:F3:44:D0:00 DHCP ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObjectCollection objMOC = objMC.GetInstances(); txtLaunch.Text = ("Name\tIP Address\tMAC Address\tType" +"\r\n"); foreach (ManagementObject objMO in objMOC) { StringBuilder builder = new StringBuilder(); object o = objMO.GetPropertyValue("IPAddress"); object m = objMO.GetPropertyValue("MACAddress"); if (o != null || m != null) { builder.Append(objMO["Description"].ToString()); builder.Append("\t"); if (o != null) builder.Append(((string[])(objMO["IPAddress"]))[0].ToString()); else builder.Append("NULL"); builder.Append("\t"); builder.Append(m.ToString()); builder.Append("\t"); builder.Append(Convert.ToBoolean(objMO["DHCPEnabled"]) ? "DHCP" : "Static"); builder.Append("\r\n"); } txtLaunch.Text = txtLaunch.Text + (builder.ToString()); I'm open to recommendations here.

• Linux Lightweight Distro and X Windows for Development

  - by Fernando Barrocal

  Heyall... I want to build a lightweight linux configuration to use for development. The first idea is to use it inside a Virtual Machine under Windows, or old Laptops with 1Gb RAM top. Maybe even a distributable environment for developers. So the whole idea is to use a LAMP server, Java Application Server (Tomcat or Jetty) and X Windows (any Window manager, from FVWM to Enlightment), Eclipse, maybe jEdit and of course Firefox. Edit: I am changing this post to compile a possible list of distros and window managers that can be used to configure a real lightweight development environment. I am using as base personal experiences on this matter. Info about the distros can be easily found in their sites. So please, focus on personal use of those systems Distros Ubuntu / Xubuntu Pros: Personal Experience in old systems or low RAM environment - @Schroeder, @SCdF Several sugestions based on personal knowledge - @Kyle, @Peter Hoffmann Gentoo Pros: Not targeted to Desktop Users - @paan Don't come with a huge ammount of applications - @paan Slackware Pros: Suggested as best performance in a wise install/configuration - @Ryan Damn Small Linux Pros: Main focus is the lightweight factor - 50MB LiveCD - @Ryan Debian Pros: Very versatile, can be configured for both heavy and lightweight computers - @Ryan APT as package manager - @Kyle Based on compatibility and usability - @Kyle -- Fell Free to add Prós and Cons on this, so we can compile a good Reference. -- X Windows suggestion keep coming about XFCE. If others are to add here, open a session for it Like the distro one :)

• Suggestions for a PHP programmer wanting to create a timer app for an internet cafe

  - by grokker

  Hi, I was asked by a friend to make a timer app for his small internet cafe. He wants to have timers on each client PCs. The timers indicate how much time has been spent by the customer. On the PC that he uses, there's another program that has the overview of all the timers and there's a button for each client PCs that allows him to blacken out the screen. It's not automatic hence the button. The problem is I haven't done any desktop apps before so that's why I'm asking you guys (the awesome people at SO) for suggestions/advice on what language/tool to use. A little info about me: I did Java but haven't tried Swing though. I know a bit about Python and Ruby too. I don't mind learning new languages as long as I get to finish or get a prototype up and running. He doesn't mind if I could show him a prototype, it's actually for me. It gives me satisfaction to see I'm progressing. I'm not planning on asking him to pay me for doing this. Whatever he gives me is fine. P.S. He's using Windows XP

• Building A True Error Handler

  - by Kevin Pirnie

  I am trying to build an error handler for my desktop application. The code Is in the class ZipCM.ErrorManager listed below. What I am finding is that the outputted file is not giving me the correct info for the StackTrace. Here is how I am trying to use it: Try '... Some stuff here! Catch ex As Exception Dim objErr As New ZipCM.ErrorManager objErr.Except = ex objErr.Stack = New System.Diagnostics.StackTrace(True) objErr.Location = "Form: SelectSite (btn_SelectSite_Click)" objErr.ParseError() objErr = Nothing End Try Here is the class: Imports System.IO Namespace ZipCM Public Class ErrorManager Public Except As Exception Public Location As String Public Stack As System.Diagnostics.StackTrace Public Sub ParseError() Dim objFile As New StreamWriter(Common.BasePath & "error_" & FormatDateTime(DateTime.Today, DateFormat.ShortDate).ToString().Replace("\", "").Replace("/", "") & ".log", True) With objFile .WriteLine("-------------------------------------------------") .WriteLine("-------------------------------------------------") .WriteLine("An Error Occured At: " & DateTime.Now) .WriteLine("-------------------------------------------------") .WriteLine("LOCATION:") .WriteLine(Location) .WriteLine("-------------------------------------------------") .WriteLine("FILENAME:") .WriteLine(Stack.GetFrame(0).GetFileName()) .WriteLine("-------------------------------------------------") .WriteLine("LINE NUMBER:") .WriteLine(Stack.GetFrame(0).GetFileLineNumber()) .WriteLine("-------------------------------------------------") .WriteLine("SOURCE:") .WriteLine(Except.Source) .WriteLine("-------------------------------------------------") .WriteLine("MESSAGE:") .WriteLine(Except.Message) .WriteLine("-------------------------------------------------") .WriteLine("DATA:") .WriteLine(Except.Data.ToString()) End With objFile.Close() objFile = Nothing End Sub End Class End Namespace What is happenning is the .GetFileLineNumber() is getting the line number from 'objErr.Stack = New System.Diagnostics.StackTrace(True)' inside my Try..Catch block. In fact, it's the exact line number that is on. Any thoughts of what is going on here, and how I can catch the real line number the error is occuring on?

• Recomendations for Creating a Picture Slide Show with Super-Smooth Transitions (For Live Presentaito

  - by Nick

  Hi everyone, I'm doing a theatrical performance, and I need a program that can read images from a folder and display them full screen on one of the computer's VGA outputs, in a predetermined order. All it needs to do is start with the first image, and when a key is pressed (space bar, right arrow), smoothly cross-fade to the next image. Sounds just like power-point right? The only reason why I can use power-point/open-office is because the "fade smoothly" transition isn't smooth enough, or configurable enough. It tends to be fast and choppy, where I would like to see a perfectly smooth fade over, say, 30 seconds. So the question is what is the best (cheap and fast) way to accomplish this? Is there a program that already does this well (for cheap or free)? OR should I try to hack at open-office's transition code? Or would it be easier to create this from scratch? Are there frameworks that might make it easier? I have web programming experience (php), but not desktop or real-time rendering. Any suggestions are appreciated!

• Testing Mobile Websites with Adobe Shadow

  - by dwahlin

  It’s no surprise that mobile development is all the rage these days. With all of the new mobile devices being released nearly every day the ability for developers to deliver mobile solutions is more important than ever. Nearly every developer or company I’ve talked to recently about mobile development in training classes, at conferences, and on consulting projects says that they need to find a solution to get existing websites into the mobile space. Although there are several different frameworks out there that can be used such as jQuery Mobile, Sencha Touch, jQTouch, and others, how do you test how your site renders on iOS, Android, Blackberry, Windows Phone, and the variety of mobile form factors out there? Although there are different virtual solutions that can be used including Electric Plum for iOS, emulators, browser plugins for resizing the laptop/desktop browser, and more, at some point you need to test on as many physical devices as possible. This can be extremely challenging and quite time consuming though especially when you consider that you have to manually enter URLs into devices and click links on each one to drill-down into sites. Adobe Labs just released a product called Adobe Shadow (thanks to Kurt Sprinzl for letting me know about it) that significantly simplifies testing sites on physical devices, debugging problems you find, and even making live modifications to HTML and CSS content while viewing a site on the device to see how rendering changes. You can view a page in your laptop/desktop browser and have it automatically pushed to all of your devices without actually touching the device (a huge time saver). See a problem with a device? Locate it using the free Chrome extension, pull up inspection tools (based on the Chrome Developer tools) and make live changes through Chrome that appear on the respective device so that it’s easy to identify how problems can be resolved. I’ve been using Adobe Shadow and am very impressed with the amount of time saved and the different features that it offers. In the rest of the post I’ll walk through how to get it installed, get it started, and use it to view and debug pages.   Getting Adobe Shadow Installed The following steps can be used to get Adobe Shadow installed: 1. Download and install Adobe Shadow on your laptop/desktop 2. Install the Adobe Shadow extension for Chrome 3. Install the Adobe Shadow app on all of your devices (you can find it in various app stores) 4. Connect your devices to Wifi. Make sure they’re on the same network that your laptop/desktop machine is on   Getting Adobe Shadow Started Once Adobe Shadow is installed, you’ll need to get it running on your laptop/desktop and on all your mobile devices. The following steps walk through that process: 1. Start the Adobe Shadow application on your laptop/desktop 2. Start the Adobe Shadow app on each of your mobile devices 3. Locate the laptop/desktop name in the list that’s shown on each mobile device: 4. Select the laptop/desktop name and a passcode will be shown: 5. Open the Adobe Shadow Chrome extension on the laptop/desktop and enter the passcode for the given device: Using Adobe Shadow to View and Modify Pages Once Adobe Shadow is up and running on your laptop/desktop and on all of your mobile devices you can navigate to a page in Chrome on the laptop/desktop and it will automatically be pushed out to all connected mobile devices. If you have 5 mobile devices setup they’ll all navigate to the page displayed in Chrome (pretty awesome!). This makes it super easy to see how a given page looks on your iPad, Android device, etc. without having to touch the device itself. If you find a problem with a page on a device you can select the device in the Chrome Adobe Shadow extension on your laptop/desktop and select the remote inspector icon (it’s the < > icon): This will pull up the Adobe Shadow remote debugging window which contains the standard Chrome Developer tool tabs such as Elements, Resources, Network, etc. Click on the Elements tab to see the HTML rendered for the target device and then drill into the respective HTML content, CSS styles, etc. As HTML elements are selected in the Adobe Shadow debugging tool they’ll be highlighted on the device itself just like they would if you were debugging a page directly in Chrome with the developer tools. Here’s an example from my Android device that shows how the page looks on the device as I select different HTML elements on the laptop/desktop: Conclusion I’m really impressed with what I’ve to this point from Adobe Shadow. Controlling pages that display on devices directly from my laptop/desktop is a big time saver and the ability to remotely see changes made through the Chrome Developer Tools (on my laptop/desktop) really pushes the tool over the top. If you’re developing mobile applications it’s definitely something to check out. It’s currently free to download and use. For additional details check out the video below:

• .Net Crystal Report printing application running on termianal service connection errors when session

  - by MrEdmundo

  I have created a .Net application to run on an App Server that gets requests for a report and prints out the requested report. The C# application uses Crystal Reports to load the report and subsequently print it out. The application is run on Server which is connected to via a Remote Desktop connection under a particular user account (required for old apps). When I disconnect from the Remote Session the application starts raising exceptions such as: Message: CrystalDecisions.Shared.CrystalReportsException: Load report failed This type of error is never raised when the Remote Session is active. The server running the app is running Windows Server 2003, my box which creates the connection is Windows XP. I appreciate this is fairly weird, however I cannot see any problem with the application deployment I have created. Does anyone know what could be cause this issue? EDIT: I bit the bullet and created the application as a windows service, obviously this doesn't take long I just wasn't convinced it would solve the problem. Anyway it doesn't!!! I have also tried removing the multi-thread code that was calling the print function asynchronously. I did this in order to simply the app and narrow down the reason it could fail. Anyway, this didn't improve the situation either! EDIT: The two errors I get are: System.Runtime.InteropServices.COMException (0x80000201): Invalid printer specified. at CrystalDecisions.ReportAppServer.Controllers.PrintOutputControllerClass.ModifyPrinterName(String newVal) at CrystalDecisions.CrystalReports.Engine.PrintOptions.set_PrinterName(String value) at Dsa.PrintServer.Service.Service.PrintCrystalReport(Report report) The printer isn't invalid, this is confirmed when 60 seconds later the time ticks and the report is printed successfully. And The request could not be submitted for background processing. at CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass.GetLastPageNumber(RequestContext pRequestContext) at CrystalDecisions.ReportSource.EromReportSourceBase.GetLastPageNumber(ReportPageRequestContext reqContext) --- End of inner exception stack trace --- at CrystalDecisions.ReportAppServer.ConvertDotNetToErom.ThrowDotNetException(Exception e) at CrystalDecisions.ReportSource.EromReportSourceBase.GetLastPageNumber(ReportPageRequestContext reqContext) at CrystalDecisions.CrystalReports.Engine.FormatEngine.PrintToPrinter(Int32 nCopies, Boolean collated, Int32 startPageN, Int32 endPageN) at CrystalDecisions.CrystalReports.Engine.ReportDocument.PrintToPrinter(Int32 nCopies, Boolean collated, Int32 startPageN, Int32 endPageN) at Dsa.PrintServer.Service.Service.PrintCrystalReport(Report report) EDIT: I ran filemon to check if there were any access issue. At the point when the error occurs file mon reports Request: OPEN | Path: C:\windows\assembly\gac_msil\system\2.0.0.0__b77a5c561934e089\ws2_32.dll | Result: NOT FOUND | Other: Attributes Error
