  • How to set Camera View as background with views over it?

    - by Android Student
    So, I'm trying to make the background to one of my apps look "futuristic." I thought of an idea to make the screen look almost transparent yet have views over it. So, it would look something like this: I'm thinking that I can use the camera to capture the background of the phone (without taking a picture, just having the real time view in the background) and then, if possible, place a semi-transparent slightly blurred ImageView over that. Finally, on top of that I can place the other views including the ImageButtons. So, my question is how would I go about doing this? I have searched but haven't found anything relevant. It must be possible; its just how to do it? I don't expect you to give me all the code as an answer, just if you have any ideas that can help or links or code that can point me in the right direction, it would be greatly appreciated! Thanks!

  • Can SQLite file copied successfully on the data folder of an unrooted android device ?

    - by student
    I know that in order to access the data folder on the device, it needs to be rooted. However, if I just want to copy the database from my assets folder to the data folder on my device, will the copying process works on an unrooted phone? The following is my Database Helper class. From logcat, I can verify that the methods call to copyDataBase(), createDataBase() and openDataBase() are returned successfully. However, I got this error message android.database.sqlite.SQLiteException: no such table: TABLE_NAME: when my application is executing rawQuery. I'm suspecting the database file is not copied successfully (cannot be too sure as I do not have access to data folder), yet the method call to copyDatabase() are not throwing any exception. What could it be? Thanks. ps: My device is still unrooted, I hope it is not the main cause of the error. public DatabaseHelper(Context context) { super(context, DB_NAME, null, 1); this.myContext = context; } public void createDataBase() throws IOException{ boolean dbExist = checkDataBase(); String s = new Boolean(dbExist).toString(); Log.d("dbExist", s ); if(dbExist){ //do nothing - database already exist Log.d("createdatabase","DB exists so do nothing"); }else{ this.getReadableDatabase(); try { copyDataBase(); Log.d("copydatabase","Successful return frm method call!"); } catch (IOException e) { throw new Error("Error copying database"); } } } private boolean checkDataBase(){ File dbFile = new File(DB_PATH + DB_NAME); return dbFile.exists(); } private void copyDataBase() throws IOException{ //Open your local db as the input stream InputStream myInput = null; myInput = myContext.getAssets().open(DB_NAME); Log.d("copydatabase","InputStream successful!"); // Path to the just created empty db String outFileName = DB_PATH + DB_NAME; //Open the empty db as the output stream OutputStream myOutput = new FileOutputStream(outFileName); //transfer bytes from the inputfile to the outputfile byte[] buffer = new byte[1024]; int length; while ((length = myInput.read(buffer))>0){ myOutput.write(buffer, 0, length); } //Close the streams myOutput.flush(); myOutput.close(); myInput.close(); } public void openDataBase() throws SQLException{ //Open the database String myPath = DB_PATH + DB_NAME; myDataBase = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY); } /* @Override public synchronized void close() { if(myDataBase != null) myDataBase.close(); super.close(); }*/ public void close() { // NOTE: openHelper must now be a member of CallDataHelper; // you currently have it as a local in your constructor if (myDataBase != null) { myDataBase.close(); } } @Override public void onCreate(SQLiteDatabase db) { } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { } }

  • OneNote 2007 - recommendation(s) of a good place/tutorials to learn features

    - by studiohack23
    I'm pretty familiar with Office 2007, however, I have just recently acquired OneNote 2007. It is such a big and powerful tool, that I'm pretty much lost on the features and how to use it. I don't really know where to start. I'm looking for some recommendation(s) on a good place to learn more about OneNote and its features and what it does...for what it's worth, I'm a student, so student perspectives on how to use/learn OneNote would be awesome! Thanks!

  • Batch update users on Active Directory

    - by FrancisV
    We have around 1000 users in the Active Directory (on Windows 2008 R2) and we would like to batch update a field (student/employee ID number) from the school management system into their existing Active Directory accounts. Obviously, each student/employee ID is unique and needs to be matched to their current Active Directory account. How can this be done? Is there a tool available for this purpose?

  • Windows 8 Radeon update broke some games

    - by Andrew
    I've been using Windows 8 Consumer Preview 32-bit on my desktop for months, and recently did a software update through Windows Update. An update for my Radeon HD 5450 driver (Catalyst) to WDDM 1.2 was in the list of updates, and installed. When I went to play CS:GO and discovered that when loaded, it would not display the GUI (menus, sometimes even the background) after a few seconds of flickering GUI. I can still navigate the menus 'by feel' and connect to and play on servers, but have no GUI, no buy menu, no map, no cross-hairs, no health indicator, etc. I have tried CS:S, which works, and Borderlands, which doesn't even load the intro videos before the first menu screen. I've tried re-installing Catalyst from the AMD website, and the beta, and tried uninstalling and reinstalling CS:GO. The problem with it (and Borderlands) still happen. What broke, and how can I fix it? I'll be reinstalling soon anyway to dump Windows 8 back to 7, but would like to be able to game until then.

  • Error with FTP since binding via httpcfg

    - by Linda
    I was in a similar posistion to this question and bound two IP addresses using httpcfg. Since doing this ftp does not seem to be working on IIS6 in Windows Server 2003. Any ideas what could be wrong? The command I ran was: httpcfg set iplisten -i xxx.xxx.x.x I get the following when I try to conenct via Filezilla: Error: Connection timed out Error: Failed to retrieve directory listing The log file is returning the following: #Software: Microsoft Internet Information Services 6.0 #Version: 1.0 #Date: 2009-08-17 13:54:05 #Fields: date time c-ip cs-username cs-method cs-uri-stem sc-status sc-win32-status 2009-08-17 13:54:05 91.85.70.17 Client [1]USER Client 331 0 2009-08-17 13:54:05 91.85.70.17 Client [1]PASS - 230 0 In the ftp site settings I have the site pointing to the IP address used using httpcfg and the port set to 21.

  • iptables rules for botnet (UDP flood) protection

    - by Petar Simeonov
    I'm currently experiencing a massive UDP attack on my server. I host a couple of gameservers, mainly Tf2, CS:GO, CS 1.6 and CS:Source, and my 1.6 server is being flooded. I tried different rules in iptables, but none of them seemed to work. I'm on a 100mbps bandwidth tariff, but the flood i receive is 500+mbps. This is the log of the latest tcpdump - http://pastebin.com/HSgFVeBs Packet length varies throughout the day. Only my gameserver ports are being flooded - 27015, 27016, 27018 via UDP packets. Are there any iptables rules, that might prevent this?

  • Getting NLog Running in Partial Trust

    - by grant.barrington
    To get things working you will need to: Strong name sign the assembly Allow Partially Trusted Callers In the AssemblyInfo.cs file you will need to add the assembly attribute for “AllowPartiallyTrustedCallers” You should now be able to get NLog working as part of a partial trust installation, except that the File target won’t work. Other targets will still work (database for example)   Changing BaseFileAppender.cs to get file logging to work In the directory \Internal\FileAppenders there is a file called “BaseFileAppender.cs”. Make a change to the function call “TryCreateFileStream()”. The error occurs here: Change the function call to be: private FileStream TryCreateFileStream(bool allowConcurrentWrite) { FileShare fileShare = FileShare.Read; if (allowConcurrentWrite) fileShare = FileShare.ReadWrite; #if DOTNET_2_0 if (_createParameters.EnableFileDelete && PlatformDetector.GetCurrentRuntimeOS() != RuntimeOS.Windows) { fileShare |= FileShare.Delete; } #endif #if !NETCF try { if (PlatformDetector.IsCurrentOSCompatibleWith(RuntimeOS.WindowsNT) || PlatformDetector.IsCurrentOSCompatibleWith(RuntimeOS.Windows)) { return WindowsCreateFile(FileName, allowConcurrentWrite); } } catch (System.Security.SecurityException secExc) { InternalLogger.Error("Security Exception Caught in WindowsCreateFile. {0}", secExc.Message); } #endif return new FileStream(FileName, FileMode.Append, FileAccess.Write, fileShare, _createParameters.BufferSize); }   Basically we wrap the call in a try..catch. If we catch a SecurityException when trying to create the FileStream using WindowsCreateFile(), we just swallow the exception and use the native System.Io.FileStream instead.

  • How to make a file load in my program when a user double clicks an associated file.

    - by Edward Boyle
    I assume in this article that file extension association has been setup by the installer. I may address file extension association at a later date, but for the purpose of this article, I address what sometimes eludes new C# programmers. This is sometimes confusing because you just don’t think about it — you have to access a file that you rarely access when making Windows forms applications, “Program.cs” static class Program { /// /// The main entry point for the application. /// [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } } There are so many ways to skin this cat, so you get to see how I skinned my last cat. static class Program { /// /// The main entry point for the application. /// [STAThread] static void Main(string[] args) { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Form1 mainf = new Form1(); if (args.Length > 0) { try { if (System.IO.File.Exists(args[0])) { mainf.LoadFile= args[0]; } } catch { MessageBox.Show("Could not open file.", "Could not open file.", MessageBoxButtons.OK, MessageBoxIcon.Information); } } Application.Run(mainf); } } It may be easy to miss, but don’t forget to add the string array for the command line arguments: static void Main(string[] args) this is not a part of the default program.cs You will notice the mainf.LoadFile property. In the main form of my program I have a property for public string LoadFile ... and the field private string loadFile = String.Empty; in the forms load event I check the value of this field. private void Form1_Load(object sender, EventArgs e) { if(loadFile != String.Empty){ // The only way this field is NOT String.empty is if we set it in // static void Main() of program.cs // LOAD it however it is needed OpenFile, SetDatabase, whatever you use. } }

  • Computer Science Degrees and Real-World Experience

    - by Steven Elliott Jr
    Recently, at a family reunion-type event I was asked by a high school student how important it is to get a computer science degree in order to get a job as a programmer in lieu of actual programming experience. The kid has been working with Python and the Blender project as he's into making games and the like; it sounds like he has some decent programming chops. Now, as someone that has gone through a computer science degree my initial response to this question is to say, "You absolutely MUST get a computer science degree in order to get a job as a programmer!" However, as I thought about this I was unsure as to whether my initial reaction was due in part to my own suffering as a CS student or because I feel that this is actually the case. Now, for me, I can say that I rarely use anything that I learned in college, in terms of the extremely hard math, algorithms, etc, etc. but I did come away with a decent attitude and the willingness to work through tough problems. I just don't know what to tell this kid; I feel like I should tell him to do the CS degree but I have hired so many programmers that majored in things like English, Philosophy, and other liberal arts-type degrees, even some that never went to college. In fact my best developer, falls into this latter category. He got started writing software for his church or something and then it took off into a passion. So, while I know this is one of those juicy potential down vote questions, I am just curious as to what everyone else thinks about this topic. Would you tell a high school kid about this? Perhaps if he/she already knows a good deal of programming and loves it he doesn't need a CS degree and could expand his horizons with a liberal arts degree. I know one of the creators of the Django web framework was a American Literature major and he is obviously a pretty gifted developer. Anyway, thanks for the consideration.

  • Alternatives for the Snippet Compiler

    - by Marko Apfel
    It seems that the Snippet Compiler is not maintained anymore. So I need an alternative – also for getting syntax highlighting for code in publications. Preferable with the possibility to conserve this highlighting by copying selections to clipboard. Snippet Compiler does not allows this for selections – only by exporting the whole file content to clipboard with HTML- or RTF-formatting (File > Export > HTML to clipboard respectively RTF to clipboard). Today I switched to LINQPad. This application offers constructing LINQ-statements as well as compiling arbitrary code snippets. But there are some other alternatives too: CS-Script - The C# Script Engine CS-Script is a CLR (Common Language Runtime) based scripting system which uses ECMA-compliant C# as a programming language. CS-Script currently targets Microsoft implementation of CLR (.NET 2.0/3.0/3.5. sharpsnippetcompiler C# Snippet Compiler is a tiny IDE to create, debug and run your C# programs CsharpRepl C# interactive shell that is part of Mono's C# compiler. An interactive shell is usually referred to as a read eval print loop or repl. The C# interactive shell is built on top of the Mono.CSharp library, a library that provides a C# compiler service that can be used to evaluate expressions and statements on the flight. What I miss is an alternative with syntax highlighting like in my Visual Studio: Instead of:

  • Versioning and Continuous Integration with project settings files

    - by Michael Stephenson
    I came across something which was a bit of a pain in the bottom the other week. Our scenario was that we had implemented a helper style assembly which had some custom configuration implemented through the project settings. I'm sure most of you are familiar with this where you end up with a settings file which is viewable through the C# project file and you can configure some basic settings. The settings are embedded in the assembly during compilation to be part of a DefaultValue attribute. You have the ability to override the settings by adding information to your app.config and if the app.config doesn’t override the settings then the embedded default is used. All normal C# stuff so far… Where our pain started was when we implement Continuous Integration and we wanted to version all of this from our build. What I was finding was that the assembly was versioned fine but the embedded default value was maintaining the non CI build version number. I ended up getting this to work by using a build task to change the version numbers in the following files: App.config Settings.settings Settings.designer.cs I think I probably could have got away with just the settings.designer.cs, but wanted to keep them all consistent incase we had to look at the code on the build server for some reason. I think the reason this was painful was because the settings.designer.cs is only updated through Visual Studio and it writes out the code to this file including the DefaultValue attribute when the project is saved rather than as part of the compilation process. The compile just compiles the already existing C# file. As I said we got it working, and it was a bit of a pain. If anyone has a better solution for this I'd love to hear it

  • Dynamically setting a value in XAML page:

    - by kaleidoscope
    This is find that I came across while developing the Silverlight screen for MSFT BPO Invoice project. Consider an instance wherein I am calling a xaml page as a popup in my parent xaml. And suppose we wanted to dynamically set a textbox field in the parent page with the  values that we select from the popup xaml. I tried the following approaches to achieve the above scenario: 1. Creating an object of the parent page within the popup xaml and initializing its textbox field.         ParentPage p = new ParentPage();         ParentPage.txtCompCode.Text = selectedValue; 2. Using App app = (App)Application.Current and storing the selected value in app. 3. Using IsolatedStorage All the above approaches failed to produce the desired effect since in the first case I did not want the parent page to get initialized over and over again and furthermore in all the approaches the value was not spontaneously rendered on the parent page. After a couple of trials and errors I decided to tweak the g.cs file of the Parent xaml. *.g.cs files are autogenerated and their purpose is to wire xaml-element with the code-behind file. This file is responsible for having reference to xaml-elements with the x:Name-property in code-behind. So I changed the access modifier of supposed textbox fields to 'static' and then directly set the value in popup xaml page as so: ParentPage.txtCompCode.Text = selectedValue; This seemed to work perfectly. We can access any xaml's g.cs file by going to the definition of InitializeComponent() present in the constructor of the xaml. PS: I may have failed to explore other more efficient ways of getting this done. So if anybody does find a better alternative please feel free to get back to me. Tinu

  • How to properly structure a project in winform?

    - by user850010
    A while ago I started to create a winform application and at that time it was small and I did not give any thought of how to structure the project. Since then I added additional features as I needed and the project folder is getting bigger and bigger and now I think it is time to structure the project in some way, but I am not sure what is the proper way, so I have few questions. How to properly restructure the project folder? At the moment I am thinking of something like this: Create Folder for Forms Create Folder for Utility classes Create Folder for Classes that contain only data What is the naming convention when adding classes? Should I also rename classes so that their functionality can be identified by just looking at their name? For example renaming all forms classes, so that their name ends with Form. Or is this not necessary if special folders for them are created? What to do, so that not all the code for main form ends up in Form1.cs Another problem I encountered is that as the main form is getting more massive with each feature I add, the code file (Form1.cs) is getting really big. I have for example a TabControl and each tab has bunch of controls and all the code ended up in Form1.cs. How to avoid this? Also, Do you know any articles or books that deal with these problems?

  • I have an MIS degree. How do I sell myself as a programmer?

    - by hydroparadise
    So, I graduated with a BSBA in Management Information Systems with honors almost 2 years ago which is more of a business degree. As of right now, I do have a job title of "Programmer", but it's more of a report writing position in an arbitrary, proprietary language called PowerOn with the occasional interesting project using more mainstream technologies like .Net and Java. I am also somewhat isoloated being the only programmer in the workplace, which I beleive is a detriment to my career path. The only people I have to bounce ideas against are those on the various SE sites. I don't regret going MIS, but over the past couple of years I have discovered my passion for coding, even though I have been doing some form of coding profesionally and as an enthusiast for years. I do want to persue my Masters in CS (at a later time), but I am not sure if I necessarily need a CS degree to get in with a team of programmers. In addition, I do have a number classes I have taken for different laguanges on the way (C++, Java, SQL, and VB.Net) I beleive my strength is in problem solving where code is just a tool to tackling to problem if needed. My question: How do I best sell myself as a programmer? Should I continue pounding out reports and wait till I have my masters in CS? Or am I viable to be a programmer as I stand?

  • Just quick: How do you call a mutator from within a constructor in the same class?

    - by Blockhead
    For a homework assignment the instructions state (within Undergrad class): You do NOT need to include a default constructor, but you must write a full parameterized constructor (it takes 4 arguments) -- this constructor calls the parent class parameterized constructor and the mutator for year level. Because Undergrad extends Student, then Student is my parent class, right? I just can't quite figure out how I'm to use my year level mutator (which is just the simplest of methods) to assign my "year" attribute. public void setYear(int inYear) { year = inYear; } public Student(String inName, String inID, int inCredits) { name = inName; id = inID; credits = inCredits; } public Undergrad(String inName, String inID, int inCredits,int inYear) { super(inName, inID, inCredits); year = inYear; } I keep missing assignments because I spend too much time on these small specific points of the homework so just asking for a little help. I swear it's the wording that throws me off on these assignments almost as often as just learning the material itself.

  • SQL Server: position based on marks

    I am using SQL Server 2008. I have a Student table in which there are following fields: 1. StudentId, 2. StudentName, 3. Marks . I want to get a resultset in which there should be a column named “Position”. Something like “Select StudentId,StudentName,Marks, as Position from Student...” so that, depending on the marks a student scored, i can evaluate them as the 1st, 2nd or 20th position. If students have the same marks, then they have the same position. Thanks. Rhys
