• Visual Studio 2012 and Game Development

  - by amongrain

  Alright, I think it's a simple question, but I got difficulties to find some answers around. I already read that XNA wouldn't be in Visual Studio 2012. I recently learned to use XNA, but since I would like to work on games, I'd like to know if there's a way to develop games using C# on Visual Studio 2012, or if I should learn everything again using C++ and Direct3D? C# is a language I like a lot, so if there's no way to do it in C# but something quite easy to use Java for game development, I'd also be interested. Thanks a lot!

• Internet connectivity issues

  - by Fishies

  I'm on 12.04, I upgraded a month ago from Windows 7 on my Sony VAIO. Everything is great except after the upgrade, I encountered Internet connectivity issues. When browsing the web or loading videos, my Internet will stop working in the middle and come back after a period of 30 seconds to 2 minutes or sometimes it just won't and I'll have to disconnect and re-connect to the network. I've noticed the issue when sending e-mails as well, they just won't send at all. It says sending request and the circle keeps spinning slowly until I get to a page where it says the page wouldn't load and gives me the reason DNS error. I tried setting OpenDNS as my DNS provider but that didn't help.

  - by Ask Me

  My screen is all messed up. I can see everything beside my start menu and when I scroll up the mouse arrow goes up and out of the screen. It's not normal. Do I need to install "GeForce 8400 GS NVIDIA" drivers on my Ubuntu 12.10 32-bit machine? Please be very patient with me and use very simple words that a simple newbie could understand. I am very very new to this OS and I don't know much of the Ubuntu/Linux terminology. Thanks guys, stay blessed.

• Ubuntu 12.10 doesn't work after update

  - by ACRTH

  12.10 doesn't work after a partial distribution update. I had some trouble before I began the update, and the Partial Update thingy appeared. It took about 6 hours to update/upgrade, don't know why. After the update, I restarted the laptop and nautilus doesn't appear nor does Unity. I can't switch to Gnome or anything else to try and fix it. The resolution is weird (doesn't fill out the right side of the screen). I'm almost sure it's Compiz who's the sinner (or me.) but I need help to get everything working again. Internet connections is fine. I have tried sudo apt-get install -f and sudo apt-get upgrade and so on.

• Can I install 12.10 on Ainol Novo7 Venus?

  - by Jens Grünwald

  Is it possible to install Ubuntu on my Ainol Novo7 Venus? I don't want any tablet-version of ubuntu, because I like ubuntu how it is and think there is no need for a tablet-version (I know there is no tablet-version, but many questions after it). So I want to install full desktop-ubuntu 12.10 with unity and everything, but I want a dual-boot with my existing android installation. Is that possible? If so, how? Is 16gb enough for ubuntu or should I buy an extra sd-card for it?

• What book do you recommend for the OCAJP certification (1Z0-803) and OCPJP (1Z0-804) [on hold]

  - by Muhammad Gelbana

  I find completely contradicting reviews for the VERY same book on amazon and even some book writers are rewarding people for good reviews so basically most of the reviews are totally fake ! You can even figure it out from the reviewer name, which you'll similar to the writer's name and assume that they could actually be from the same country and the reviewer is just being helpful, to the book writer of course ! I can't make my mind for which book I should buy ! I only need a book or two that covers the Java associate and professional topics very well, not just an overview, I need a material that covers everything from A to Z. Even though I've been developing in Java for around 4.5 years but I must not know a detail or two. Would someone kindly shed some light on a good book based on actual experience with the book ? THANK YOU !

• NetBeans 7.1 Release Candidate (RC) 1 is here

  - by alexismp

  NetBeans 7.1 RC 1 is here. Grab it from the usual place! As previously discussed, NetBeans 7.1 has full JavaFX 2.0 support but also a lot in store for Java EE and Web developers (CDI in particular is very neat). One of my personal favorite feature is that Deploy on Save is now set by default on Maven projects. Maybe one important part that didn't get proper coverage so far is CSS 3 support, an important feature which can be used from both Java EE and PHP but also from JavaFX. Java Downloads of NetBeans 7.1 start at 69 MB and a 166 MB download will get you everything you need to start coding right away with Java EE - a great tool and a fully integrated runtime (GlassFish 3.1.1). You really need to be not using Maven, not be interested in recent standards (Java EE 6, Java SE 7, Java FX 2.0, ...) and like to hand-craft assemble your IDE to afford ignoring NetBeans nowadays.

• Ubuntu 14.04 crashes after several seconds

  - by AndrewJoyce86

  I just installed Ubuntu on my Compaq desktop and everything seemed to go well. The desktop appeared just like it should... Only then this happens, seconds later: Crash Something tells me that this is not supposed to be happening. I did not partition, I replaced Windows 7 with Ubuntu. When I try to run off the USB stick I used, I get this: USB So, what do I do, now? Should I try to reinstall? Is the ISO bad, somehow?

• What is the most handy function you've ever came across? [closed]

  - by Viniyo Shouta

  Obviously everything is 'handy' when it comes to programming terms, but some get a highlight spot, like containers, matrix trasnformation functions and many others. But in this case please mention the one it was more handy to you, saved you from sparing hours resolving a problem, or even the one you like more, What is it and what does it does? I'll start with an example. Language: C++ Function: std::sort (STL) What does it does: Arranges the elements in a specified range into a nondescending order or according to an ordering criterion specified by a binary predicate. (It arranges a container in decreasing order) Why of this question? Because I want to learn how to if possible make my own implementations of these functions for pure studying purposes, to enhance knowledge

• What is the proper way to use string::find to look for a word? [migrated]

  - by RubyKing

  How would I look through a string for a word rather then each character in that word. I have my code here and it always seems to find everything that is .obj even if its o or b or j or "." I checked the docuementation here but was unable to find an answer. Here is my code: string &str = *it; if(it->find(".obj")) { cout << "Found .Obj" << endl; } I also tried to use string::compare but that failed.

• No partitions in Ubuntu isntallation

  - by user204212

  Today, with the new version of Ubuntu, I have decided to install it in my laptot, but running with Windows 8, which is the OS I have installed now and that I don't want to uninstall, because I need some programs. I have downloaded it and burned into a CD. Everything in the "installation" goes right untill I have to choose where to install it. It doesn't recognise my Windows 8 and, moreover, it sees my disk as it was all empty space (500Gb). I can't install it and I don't know what to do, so let's see if you can help, because you know a lot more than me in this topic :) Thanks!

• How do I get the wireless card on a Lenovo S205 working?

  - by user206829

  I tried to install 12.04, 13.04, and now 13.10 on the machine and followed all the instructions that made sense that I could find and still have not gotten wifi to work. It keeps it hard blocked for some reason, not sure why and not sure anyone out there either has figured it out because I would have found it on Google. When I boot from the formatted USB drive, I have WiFi and everything working, why doesn't work after the USB drive is removed? What driver is the USB/wubi or whatever using so that I can install it and have things working? I could have used wubi and installed Ubuntu like that, but I want to make this machine a fully dedicated Ubuntu machine. The laptop is a Lenovo S205 in case anyone can help. I really would like to use 12.04 or higher, i don't want to downgrade to an older version of Ubuntu if at all possible.

• Need some help fixing fonts (11.04 Alpha 3)

  - by Spacecraft

  Hi I changed my Application Font and Window Font to something much better looking but it has a few problems. The font is Umpush Light. It's doing this in the software center: http://img851.imageshack.us/img851/8307/workspace1004.png If I increase the font size from 11 to 12, that problem goes away, but then everything is too large. When I increase it this also happens: http://img819.imageshack.us/img819/6231/workspace1006e.png It starts moving the text in the search box up, and the "All Applications" drop down gets messed up too. It seems like there is too much padding around the font or something. Anyone have any ideas on how I can fix this?

• Ubuntu 12.10 - launcher stays hidden

  - by Mieszko

  Just upgraded to 12.10 today. Everything seems fine for now, aprat from one thing: The launcher on the left side of the screen doesn't come up after moving the cursor to the left side of the screen. It IS there since it show the app start animation and I can have it on top all the time, but I'm really fond of it being hidden most of the time. I did check the sensitivity settings and even set it up to MAX (thus high) and it changes nothing. Please help ;) Cheers

• Mac HDD Is Encrypted

  - by user206844

  I have the hard drive from a PowerMac G5, which was my old computer before it died and I upgraded to Ubuntu Studio. The hard drive its self still works well, but on Ubuntu I can't access most of the files. I plugged it into my MacBook Air and changed some of the perms on some of the folders as a test. This worked for a few, but for others, I was getting the same message Cannot access folder. Access denied. I would like to use this as an external HDD (I have a case and everything), but it's kind of pointless if I can't access the folders that I want. After looking around for a couple of hours, I couldn't find anything that actually gave me an answer. I would like to know if: Anybody else has come upon this problem, If so, have you found a solution? and, What is it?

  Possible Duplicate: What is a good way to get many inbound links to your site? I'm probably taking a huge chance here, but I've become a bit desperate. We've paid many a dollar to companies to help push up our page rank, but with no results. I myself have tried everything. Page Rank got up to 5, and now it seems to have gone down to 4. Any advice, even if you point me to an AFFORDABLE and RELIABLE company, I would really appreciate it?

• C# Excel file OLEDB read HTML IMPORT

  - by Michel van Engelen

  Hi, I have to automate something for the finance dpt. I've got an Excel file which I want to read using OleDb: string connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=A_File.xls;Extended Properties=""HTML Import;IMEX=1;"""; using (OleDbConnection connection = new OleDbConnection()) { using (DbCommand command = connection.CreateCommand()) { connection.ConnectionString = connectionString; connection.Open(); DataTable dtSchema = connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null); if( (null == dtSchema) || ( dtSchema.Rows.Count <= 0 ) ) { //raise exception if needed } command.CommandText = "SELECT * FROM [NameOfTheWorksheet$]"; using (DbDataReader dr = command.ExecuteReader()) { while (dr.Read()) { //do something with the data } } } } Normally the connectionstring would have an extended property "Excel 8.0", but the file can't be read that way because it seems to be an html file renamed to .xls. when I copy the data from the xls to a new xls, I can read the new xls with the E.P. set to "Excel 8.0". Yes, I can read the file by creating an instance of Excel, but I rather not.. Any idea how I can read the xls using OleDb without making manual changes to the xls or by playing with ranges in a instanciated Excel? Regards, Michel

• LINQ to Entities exceptions (ElementAtOrDefault and CompareObjectEqual)

  - by OffApps Cory

  I am working on a shipping platform which will eventually automate shipping through several major carriers. I have a ShipmentsView Usercontrol which displayes a list of Shipments (returned by EntityFramework), and when a user clicks on a shipment item, it spawns a ShipmentEditView and passes the ShipmentID (RecordKey) to that view. I initially wrestled with trying to get the context from the parent (ShipmentsView) and finally gave up resolving to get to it later. I wanted to do this to keep a single instance of the context. anyhow, I now create a new instance of the context in my ShipmentEditViewModel, and query against it for the Shipment record. I know I could just pass the record, but I wanted to use the Ocean Framework that Karl Shifflett wrote and don't want to muck about writing new transition methods. So anyhow, I query and when stepping through, I can see that it returns a record, as soon as execution reached the point where it assigned the query result to the e.Result property, it throws up the following exception depending on the query I used. LINQToEntities Dim RecordID As Decimal = CDec(e.Argument) Dim myResult = From ship In _Context.Shipment _ Where ship.ShipID = e.Argument _ Select ship Select Case myResult.Count Case 0 e.Result = New Shipment Case 1 e.Result = myResult(0) Case Else e.Result = Nothing End Select "LINQ to Entities does not recognize the method 'System.Object.CompareObjectEqual(System.Object, System.Object, Boolean)' method, and this method cannot be translated into a store expression. LINQToEntities via Method calls Dim RecordID As Decimal = CDec(e.Argument) Dim myResult = _Context.Shipment.Where(Function(s) s.ShipID = RecordID) Select Case myResult.Count Case 0 e.Result = New Shipment Case 1 e.Result = myResult(0) Case Else e.Result = Nothing End Select LINQ to Entities does not recognize the method 'SnazzyShippingDAL.Shipment ElementAtOrDefault[Shipment] (System.Linq.IQueryable`1[SnazzyShippingDAL.Shipment], Int32)' method, and this method cannot be translated into a store expression. I have been trying to get this thing to display a record for like three days. i am seriously thinking about going back and re=-engineering it without the MVVM pattern (which I realize I am only starting to learn and understand) if only to make the &$^%ed thing work. Any help will be muchly appreciated. Cory

• Retrieving the COM class factory for component error while generating word document

  - by TheDPQ

  Hello, I am trying to edit a word document from VB.NET using for the most part this code: How to automate Word from Visual Basic .NET to create a new document http://support.microsoft.com/kb/316383 It works fine on my machine but when i publish to the server i get the following error. Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80070005. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.UnauthorizedAccessException: Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80070005. The actual error happens when i try to just create a word application object Dim oWord As New Word.Application Using Visual Studio 2008 and VB.NET 3.5. I made a reference to the "Microsoft Word 10.0 Object Library" and i see Interop.Word.dll file in the bin directory. Using MS Office 2003 on development machine and Windows Server 2003 Still fairly new to .NET and don't have much knowledge about window server, but "UnauthorizedAccessException" sounds like a permission issue. I'm wondering if someone could point me in the right direction on what i might need to do to give my little application access to use word. Thank you so much for your time.

• A tool to aid completion of missing or incomplete source code documentation

  - by Pekka

  I have several finished, older PHP projects with a lot of includes that I would like to document in javadoc/phpDocumentor style. While working through each file manually and being forced to do a code review alongside the documenting would be the best thing, I am, simply out of time constraints, interested in tools to help me automate the task as much as possible. The tool I am thinking about would ideally have the following features: Parse a PHP project tree and tell me where there are undocumented files, classes, and functions/methods (i.e. elements missing the appropriate docblock comment) Provide a method to half-way easily add the missing docblocks by creating the empty structures and, ideally, opening the file in an editor (internal or external I don't care) so I can put in the description. Optional: Automatic recognition of parameter types, return values and such. But that's not really required. The language in question is PHP, though I could imagine that a C/Java tool might be able to handle PHP files after some tweaking. Looking forward to your suggestions! Bounty There are already very good suggestions for this (that I have not yet had the time to check out) to point out the gaps, but none yet providing aid in filling them. I want to give the question some more exposure, maybe there is some sort of a graphical extension to php_codesniffer to achieve the level of automation I'm dreaming of. Looking forward to any additional input!
