• What is the proper way to Windows 7/Ubuntu 10.10 Dual-Triple Boot Partitioning for Laptop OEM?

  - by Denja

  Hi Linux Community, I find my self struggling with the slowness of windows OS once again. It's Time to change with the Ubuntu 10.10 64bit for I like to use a faster Operating System. My Hard Disk laptop has a RECOVERY and HP_TOOLS partition they are both Primary. I Have the System Recovery DVD for Windows 64bit should anything bad happen. Here's the layout I used with windows before: * (C:) Windows 7 system partition NTFS - 284,89GB (Primary,ad Boot,Pagefile,Dump) * HP_TOOLS system partition FAT32 - 99MB (Primary) * (D:) RECOVERY partition NTFS - 12,90GB (Primary) * SYSTEM partition NTFS 199MB (Primary) Here's the layout I wanted to make: * (C:) Windows 7 system partition NTFS - 60GB (Primary) (sda1) * (D:) Windows DATA partition (user files) NTFS - 120GB(Primary)(sda2);wanna share with Linux * Linux root Ext4 - 10GB (Extended)(sda3) (Ubuntu 10.10 64bit) * Linux home Ext3 - 90GB (Extended)(sda4) (Ubuntu 10.10 64bit) * Linux swap swap- RAM size, 3GB (sda5) * Linux root Ext3- 18GB (Extended) (sda6) (OpenSuse or Puppy or kubuntu) Here is my New Ubuntu 10.10 64bit layout in use now: * SYSTEM partition NTFS 199MB (Primary) (sda1) * (C:) Windows 7 system partition NTFS - 90GB (Primary) (sda2) * (D:) Windows 7 RECOVERY partition NTFS - 12,90GB (Primary) (sda3) * Linux system partition EXTENDED - 195,1GB (Logical) * Linux root Ext4- 10GB (Extended) (sda4) * Linux swap swap- RAMx2 size, 6,1GB (sda5) * Linux home Ext3- 179GB (Extended) (sda6) When I installed Ubuntu,I didn't know if I could wipe all previous partitions,because of the RECOVERY partition. So I just made the space for my extended partition with GParted by deleting the HP_TOOLS (Fat32). By doing this I managed somehow to install Ubuntu 64 with Success. And I also made the partitions for the swap or a third Linux OS as Jordan suggested. But I couldn't actually make the partitions for the shared NTFS.(no option!) Question 1: What is the proper way to Windows 7/Ubuntu 10.10 Dual-Triple Boot Partitioning for Laptop OEM?? Thank you in advance for your advises and suggestions and Happy New Year to All!!

• How to Omit the Page Number From the First Page of a Word 2013 Document Without Using Sections

  - by Lori Kaufman

  Normally, the first page, or cover page, of a document does not have a page number or other header or footer text. You can avoid putting a page number on the first page using sections, but there is an easier way to do this. If you don’t plan to use sections in any other part of your document, you may want to avoid using them completely. We will show you how to easily take the page number off the cover page and start the page numbering at one on the second page of your document by simply using a footer (or a header) and changing one setting. Click the Page Layout tab. In the Page Setup section of the Page Layout tab, click the Page Setup dialog box launcher icon in the lower, right corner of the section. On the Page Setup dialog box, click the Layout tab and select the Different first page check box in the Headers and footers section so there is a check mark in the box. Click OK. You’ll notice there is no page number on the first page of your document now. However, you might want the second page to be page one of your document, only to find it is currently page two. To change the page number on the second page to one, click the Insert tab. In the Header & Footer section of the Insert tab, click Page Number and select Format Page Numbers from the drop-down menu. On the Page Number Format dialog box, select Start at in the Page numbering section. Enter 0 in the edit box and click OK. This allows the second page of your document to be labeled as page one. You can use the drop-down menu on the Format Page Numbers button in the Header & Footer section of the Insert tab to add page numbers to your document as well. Easily insert formatted page numbers at the top or bottom of the page or in the page margins. Use the same menu to remove page numbers from your document.

• What is the right way to Windows 7/Ubuntu 10.10 Dual-Triple Boot Partitioning for Laptop OEM?

  - by Denja

  Hi Linux Community, I find my self struggling with the ever slow and buggy windoze OS once again. It's Time to change with the Ubuntu 10.10 64bit as a really faster Operating System.

• GLSL Normals not transforming propertly

  - by instancedName

  I've been stuck on this problem for two days. I've read many articles about transforming normals, but I'm just totaly stuck. I understand choping off W component for "turning off" translation, and doing inverse/traspose transformation for non-uniform scaling problem, but my bug seems to be from a different source. So, I've imported a simple ball into OpenGL. Only transformation that I'm applying is rotation over time. But when my ball rotates, the illuminated part of the ball moves around just as it would if direction light direction was changing. I just can't figure out what is the problem. Can anyone help me with this? Here's the GLSL code: Vertex Shader: #version 440 core uniform mat4 World, View, Projection; layout(location = 0) in vec3 VertexPosition; layout(location = 1) in vec3 VertexColor; layout(location = 2) in vec3 VertexNormal; out vec4 Color; out vec3 Normal; void main() { Color = vec4(VertexColor, 1.0); vec4 n = World * vec4(VertexNormal, 0.0f); Normal = n.xyz; gl_Position = Projection * View * World * vec4(VertexPosition, 1.0); } Fragment Shader: #version 440 core uniform vec3 LightDirection = vec3(0.0, 0.0, -1.0); uniform vec3 LightColor = vec3(1f); in vec4 Color; in vec3 Normal; out vec4 FragColor; void main() { diffuse = max(0.0, dot(normalize(-LightDirection), normalize(Normal))); vec4 scatteredLight = vec4(LightColor * diffuse, 1.0f); FragColor = min(Color * scatteredLight, vec4(1.0)); }

• Algorithm for procedural city generation?

  - by Zove Games

  I am planning on making a (simple) procedural city generator using Java. I need ideas on whan algorithm to use for the layout, and the actual buildings. The city will mostly have skyscrapers, not really much complex stuff. For the layout I already have a simple algorithm implemented: Create a Map with java.awt.Point keys and Integer values. Fill it with all the points in the city's bounds with the value as -1 (unnassigned) Shuffle the map, and assign the 1st 10 of the keys IDs (from 1-10) Loop until all points have IDs: Loop though all points: Assign points next to an assigned point IDs of the point next to them, if 2 or more points border the point, then randomly choose which ID the point will get. You will end up with 10 random regions. Make roads bordering these regions. Fill the inside of each region with a randomly spaced and randomly rotated grid PROBLEM: This is not the fastest way to do it. What algorithm should I use for the layout. And what should I use to make each building's design? I don't even know how I'm going to do that yet (fractals maybe). I just need some ideas, not actual code.

• How do I access a JPG embedded in my JAR file via a URL object? What would be the address?

  - by dacracot

  I've bundled a JPG inside of my application's JAR file. I need to access it, preferably via a URL object from the code in the same JAR. But I've no idea how to construct the address. I'm guessing it would be a "file:///" but what comes after that?

• Tuples vs. Anonymous Types vs. Expando object. (in regards to LINQ queries)

  - by punkouter

  I am a beginner who finally started understanding anonymous types. (see old post http://stackoverflow.com/questions/3010147/what-is-the-return-type-for-a-anonymous-linq-query-select-what-is-the-best-way-t) So in LINQ queries you form the type of return value you want within the linq query right? It seems the way to do this is anonymous type right? Can someone explain to me if and when I could use a Tuple/Expando object instead? They all seem very simliar?

• How do I declare a constructor for an 'object' class type in Scala? I.e., a one time operation for the singleton.

  - by Zack

  I know that objects are treated pretty much like singletons in scala. However, I have been unable to find an elegant way to specify default behavior on initial instantiation. I can accomplish this by just putting code into the body of the object declaration but this seems overly hacky. Using an apply doesn't really work because it can be called multiple times and doesn't really make sense for this use case. Any ideas on how to do this?

• Lightbox image / link URL

  - by GSTAR

  Basically I have a slightly non-standard implementation of FancyBox. By default you have to include a link to the large version of the image so that the Lightbox can display it. However, in my implementation, the image link URLs point to a script rather than directly to the image file. So for example, instead of: <a href="mysite/images/myimage.jpg" rel="gallery"> I have: <a href="mysite/photos/view/abc123" rel="gallery"> The above URL points to a function: public function actionPhotos($view) { $photo=Photo::model()->find('name=:name', array(':name'=>$view)); if(!empty($photo)) { $this->renderPartial('_photo', array('photo'=>$photo, true)); } } The "$this-renderPartial()" bit simply calls a layout file which includes a standard HTML tag to output. Now when the user clicks on a thumbnail, the above function is called and the large image is displayed in the Lightbox. Now if the user right clicks on the thumbnail and selects "open in new tab/window" then the image is displayed in the browser as per normal, i.e. just the image. I want to change this so that it displays the image within a layout. In the above code I can include the following and put it in an IF statement: $this->render('photos', array('photo'=>$photo)); This will call the layout file "photos" which contains the layout to display the image in. I have a specific limitation for this - the image URL must remain the same, i.e. no additional GET variables in the URL. However if we can pass in a GET variable in the background then that is OK. I will most likely need to change my function above so that it calls a different file for this functionality. EDIT: To demonstrate exactly what I am trying to do, check out the following: http://www.starnow.co.uk/KimberleyMarren Go to the photos tab and hover over a thumbnail - note the URL. Click the thumbnail and it will open up in the Lightbox. Next right click on that same thumbnail and select "open in new tab/new window". You will notice that the image is now displayed in a layout. So that same URL is used for displaying the image in the Lightbox and on its own page. The way StarNow have done this is using some crazy long JavaScript functionality, which I'm not too keen on replicating.

• .NET OCRing an Image

  - by Kirschstein

  I'm trying to use MODI to OCR a window's program. It works fine for screenshots I grab programmatically using win32 interop like this: public string SaveScreenShotToFile() { RECT rc; GetWindowRect(_hWnd, out rc); int width = rc.right - rc.left; int height = rc.bottom - rc.top; Bitmap bmp = new Bitmap(width, height); Graphics gfxBmp = Graphics.FromImage(bmp); IntPtr hdcBitmap = gfxBmp.GetHdc(); PrintWindow(_hWnd, hdcBitmap, 0); gfxBmp.ReleaseHdc(hdcBitmap); gfxBmp.Dispose(); string fileName = @"c:\temp\screenshots\" + Guid.NewGuid().ToString() + ".bmp"; bmp.Save(fileName); return fileName; } This image is then saved to a file and ran through MODI like this: private string GetTextFromImage(string fileName) { MODI.Document doc = new MODI.DocumentClass(); doc.Create(fileName); doc.OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, true, true); MODI.Image img = (MODI.Image)doc.Images[0]; MODI.Layout layout = img.Layout; StringBuilder sb = new StringBuilder(); for (int i = 0; i < layout.Words.Count; i++) { MODI.Word word = (MODI.Word)layout.Words[i]; sb.Append(word.Text); sb.Append(" "); } if (sb.Length > 1) sb.Length--; return sb.ToString(); } This part works fine, however, I don't want to OCR the entire screenshot, just portions of it. I try cropping the image programmatically like this: private string SaveToCroppedImage(Bitmap original) { Bitmap result = original.Clone(new Rectangle(0, 0, 250, 250), original.PixelFormat); var fileName = "c:\\" + Guid.NewGuid().ToString() + ".bmp"; result.Save(fileName, original.RawFormat); return fileName; } and then OCRing this smaller image, however MODI throws an exception; 'OCR running error', the error code is -959967087. Why can MODI handle the original bitmap but not the smaller version taken from it?

• Redundant margins when adding ImageView to ScrollView in Android.

  - by Shmuel Meymann

  Hi.. I have been trying to use a ScrollView on a single ImageView with a JPG (~770 x 1024) over an AVD that's 600x800. My main.xml is: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ScrollView android:id="@+id/scroller" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout> Now, I add a single ImageView with setContentView(R.layout.main); ScrollView sv = (ScrollView)findViewById( R.id.scroller ); ImageView iv = new ImageView(this); iv.setImageDrawable( new BitmapDrawable( "/sdcard/770x1024.jpg" ) ); // same happens with ScaleDrawable. iv.setScaleType( ScaleType.CENTER_INSIDE ); sv.addView( sv ); // and it does not go any better if I use Linear Layout between the ScrollView and the ImageView. The result is The image was displayed in a middle of a ScrollView, wrapped with background area on top and bottom as following: ##### ##### image . . . ##### ##### Where ##### stands for background area I tried to set the background of the ImageView red, and it verified that the blank margins were ImageView background. iv.setBackgroundColor( color.Red ); Where I would expect the image to take no more than its size (scaled to the AVD size) and I expect the ScrollView to let me scroll over the remainder (if any). For some reason, I see that the drawable size is 600x1024. Moreover I tried to add a LinearLayout with a dummy text view such as the linear layout is a parent to the ImageView and the TextView, and the ScrollView is a parent to the LinearLayout. LinearLayout dummy = new LinearLayout( this ); dummy.addView(iv); TextView someTextView = new TextView( this ); someTextView.setLayoutParams(new LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT )); dummy.addView( someTextView ); sv.addView( dummy ); The result was very peculiar: The entire layout was set into the width of a text-less text view (19). It is important for me to avoid stretching the image. What is the recommended way to implement a display of a page that can be potentially scrolled? Do I have to do it manually with a plain layout and scrolling upon OnMove events? Thanks Shmuel

• How to update a TextView on ButtonClick with Spinner(s) values

  - by source.rar

  Hi, I am trying to populate a TextView based on the current selected options in 3 Spinner(s) but cant seem to figure out how to retrieve the selected values from the Spinners to invoke the update function with. Here is my current code (quite messy but I'm just learning Java :)), public class AgeFun extends Activity { private String[] dayNames; private String[] yearArray; private final static int START_YEAR = 1990; private static TextView textDisp; private Button calcButton; private static Spinner spinnerDay, spinnerYear, spinnerMonth; private static ArrayAdapter<?> monthAdapter, dayAdapter, yearAdapter; private int year, month, day; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); year = 2000; month = 1; day = 1; textDisp = (TextView) findViewById(R.id.textView1); calcButton = (Button) findViewById(R.id.button); calcButton.setOnClickListener(new OnClickListener() { public void onClick(View v) { // Perform action on clicks AgeFun.updateAge(year, month, day); } }); // Month spinner spinnerMonth = (Spinner) findViewById(R.id.spinnerFirst); monthAdapter = ArrayAdapter.createFromResource( this, R.array.monthList, android.R.layout.simple_spinner_item); monthAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinnerMonth.setAdapter(monthAdapter); // Day spinner dayNames = new String[31]; for(int i =1; i <= 31; ++i) { dayNames[i-1] = Integer.toString(i); } spinnerDay = (Spinner) findViewById(R.id.spinnerSecond); dayAdapter = new ArrayAdapter<CharSequence>(this, android.R.layout.simple_spinner_item, dayNames); spinnerDay.setAdapter(dayAdapter); // Year spinner yearArray = new String[40]; for(int i =0; i < 40; ++i) { yearArray[i] = Integer.toString(START_YEAR+i); } spinnerYear = (Spinner) findViewById(R.id.spinnerThird); yearAdapter = new ArrayAdapter<CharSequence>(this, android.R.layout.simple_spinner_item, yearArray); spinnerYear.setAdapter(yearAdapter); updateAge(2000,1,1); } private static void updateAge(int year, int month, int day) { Date dob = new GregorianCalendar(year, month, day).getTime(); Date currDate = new Date(); long age = (currDate.getTime() - dob.getTime()) / (1000 * 60 * 60 * 24) / 365; textDisp.setText("Your are " + Long.toString(age) + " years old"); } } Any help with this would be great.

• Updating table from async task android

  - by CantChooseUsernames

  I'm following this tutorial: http://huuah.com/android-progress-bar-and-thread-updating/ to learn how to make progress bars. I'm trying to show the progress bar on top of my activity and have it update the activity's table view in the background. So I created an async task for the dialog that takes a callback: package com.lib.bookworm; import android.app.ProgressDialog; import android.content.Context; import android.os.AsyncTask; public class UIThreadProgress extends AsyncTask<Void, Void, Void> { private UIThreadCallback callback = null; private ProgressDialog dialog = null; private int maxValue = 100, incAmount = 1; private Context context = null; public UIThreadProgress(Context context, UIThreadCallback callback) { this.context = context; this.callback = callback; } @Override protected Void doInBackground(Void... args) { while(this.callback.condition()) { this.callback.run(); this.publishProgress(); } return null; } @Override protected void onProgressUpdate(Void... values) { super.onProgressUpdate(values); dialog.incrementProgressBy(incAmount); }; @Override protected void onPreExecute() { super.onPreExecute(); dialog = new ProgressDialog(context); dialog.setCancelable(true); dialog.setMessage("Loading..."); dialog.setProgress(0); dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); dialog.setMax(maxValue); dialog.show(); } @Override protected void onPostExecute(Void result) { super.onPostExecute(result); if (this.dialog.isShowing()) { this.dialog.dismiss(); } this.callback.onThreadFinish(); } } And in my activity, I do: final String page = htmlPage.substring(start, end).trim(); //Create new instance of the AsyncTask.. new UIThreadProgress(this, new UIThreadCallback() { @Override public void run() { row_id = makeTableRow(row_id, layout, params, matcher); //ADD a row to the table layout. } @Override public void onThreadFinish() { System.out.println("FINISHED!!"); } @Override public boolean condition() { return matcher.find(); } }).execute(); So the above creates an async task to run to update a table layout activity while showing the progress bar that displays how much work has been done.. However, I get an error saying that only the thread that started the activity can update its views. I tried doing: MainActivity.this.runOnUiThread(new Runnable() { @Override public void run() { row_id = makeTableRow(row_id, layout, params, matcher); //ADD a row to the table layout. } } But this gives me synchronization errors.. Any ideas how I can display progress and at the same time update my table in the background? Currently my UI looks like:

• I need help on my C++ assignment using MS Visual C++

  - by krayzwytie

  Ok, so I don't want you to do my homework for me, but I'm a little lost with this final assignment and need all the help I can get. Learning about programming is tough enough, but doing it online is next to impossible for me... Now, to get to the program, I am going to paste what I have so far. This includes mostly //comments and what I have written so far. If you can help me figure out where all the errors are and how to complete the assignment, I will really appreciate it. Like I said, I don't want you to do my homework for me (it's my final), but any constructive criticism is welcome. This is my final assignment for this class and it is due tomorrow (Sunday before midnight, Arizona time). This is the assignment: Examine the following situation: o Your company, Datamax, Inc., is in the process of automating its payroll systems. Your manager has asked you to create a program that calculates overtime pay for all employees. Your program must take into account the employee’s salary, total hours worked, and hours worked more than 40 in a week, and then provide an output that is useful and easily understood by company management. • Compile your program utilizing the following background information and the code outline in Appendix D (included in the code section). • Submit your project as an attachment including the code and the output. Company Background: o Three employees: Mark, John, and Mary o The end user needs to be prompted for three specific pieces of input—name, hours worked, and hourly wage. o Calculate overtime if input is greater than 40 hours per week. o Provide six test plans to verify the logic within the program. o Plan 1 must display the proper information for employee #1 with overtime pay. o Plan 2 must display the proper information for employee #1 with no overtime pay. o Plans 3-6 are duplicates of plan 1 and 2 but for the other employees. Program Requirements: o Define a base class to use for the entire program. o The class holds the function calls and the variables related to the overtime pay calculations. o Define one object per employee. Note there will be three employees. o Your program must take the objects created and implement calculations based on total salaries, total hours, and the total number of overtime hours. See the Employee Summary Data section of the sample output. Logic Steps to Complete Your Program: o Define your base class. o Define your objects from your base class. o Prompt for user input, updating your object classes for all three users. o Implement your overtime pay calculations. o Display overtime or regular time pay calculations. See the sample output below. o Implement object calculations by summarizing your employee objects and display the summary information in the example below. And this is the code: // Final_Project.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <iostream> #include <string> #include <iomanip> using namespace std; // //CLASS DECLARATION SECTION // class CEmployee { public: void ImplementCalculations(string EmployeeName, double hours, double wage); void DisplayEmployInformation(void); void Addsomethingup (CEmployee, CEmployee, CEmployee); string EmployeeName ; int hours ; int overtime_hours ; int iTotal_hours ; int iTotal_OvertimeHours ; float wage ; float basepay ; float overtime_pay ; float overtime_extra ; float iTotal_salaries ; float iIndividualSalary ; }; int main() { system("cls"); cout << "Welcome to the Employee Pay Center"; /* Use this section to define your objects.

No I won't post the WSDL, it's hosted behind a firewall, for a vertical stack product. No, I can't change the data sender. Is this somehow automagically handled elsewhere and I just don't know what I don't know? I think I want to do some sort of message sink leading into this method, to intercept the soapenv:Body, but obviously this is for errors, so I'm not going to get errors every time. I'm not entirely sure how to handle this, but some pointers would be nice.

• how do you make a "concurrent queue safe" lazy loader (singleton manager) in objective-c

  - by Rich

  Hi, I made this class that turns any object into a singleton, but I know that it's not "concurrent queue safe." Could someone please explain to me how to do this, or better yet, show me the code. To be clear I want to know how to use this with operation queues and dispatch queues (NSOperationQueue and Grand Central Dispatch) on iOS. Thanks in advance, Rich EDIT: I had an idea for how to do it. If someone could confirm it for me I'll do it and post the code. The idea is that proxies make queues all on their own. So if I make a mutable proxy (like Apple does in key-value coding/observing) for any object that it's supposed to return, and always return the same proxy for the same object/identifier pair (using the same kind of lazy loading technique as I used to create the singletons), the proxies would automatically queue up the any messages to the singletons, and make it totally thread safe. IMHO this seems like a lot of work to do, so I don't want to do it if it's not gonna work, or if it's gonna slow my apps down to a crawl. Here's my non-thread safe code: RMSingletonCollector.h // // RMSingletonCollector.h // RMSingletonCollector // // Created by Rich Meade-Miller on 2/11/11. // Copyright 2011 Rich Meade-Miller.

• I need help on my C++ assignment using Microsoft Visual C++

  - by krayzwytie

  Ok, so I don't want you to do my homework for me, but I'm a little lost with this final assignment and need all the help I can get. Learning about programming is tough enough, but doing it online is next to impossible for me... Now, to get to the program, I am going to paste what I have so far. This includes mostly //comments and what I have written so far. If you can help me figure out where all the errors are and how to complete the assignment, I will really appreciate it. Like I said, I don't want you to do my homework for me (it's my final), but any constructive criticism is welcome. This is my final assignment for this class and it is due tomorrow (Sunday before midnight, Arizona time). This is the assignment: Examine the following situation: Your company, Datamax, Inc., is in the process of automating its payroll systems. Your manager has asked you to create a program that calculates overtime pay for all employees. Your program must take into account the employee’s salary, total hours worked, and hours worked more than 40 in a week, and then provide an output that is useful and easily understood by company management. Compile your program utilizing the following background information and the code outline in Appendix D (included in the code section). Submit your project as an attachment including the code and the output. Company Background: Three employees: Mark, John, and Mary The end user needs to be prompted for three specific pieces of input—name, hours worked, and hourly wage. Calculate overtime if input is greater than 40 hours per week. Provide six test plans to verify the logic within the program. Plan 1 must display the proper information for employee #1 with overtime pay. Plan 2 must display the proper information for employee #1 with no overtime pay. Plans 3-6 are duplicates of plan 1 and 2 but for the other employees. Program Requirements: Define a base class to use for the entire program. The class holds the function calls and the variables related to the overtime pay calculations. Define one object per employee. Note there will be three employees. Your program must take the objects created and implement calculations based on total salaries, total hours, and the total number of overtime hours. See the Employee Summary Data section of the sample output. Logic Steps to Complete Your Program: Define your base class. Define your objects from your base class. Prompt for user input, updating your object classes for all three users. Implement your overtime pay calculations. Display overtime or regular time pay calculations. See the sample output below. Implement object calculations by summarizing your employee objects and display the summary information in the example below. And this is the code: // Final_Project.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <iostream> #include <string> #include <iomanip> using namespace std; // //CLASS DECLARATION SECTION // class CEmployee { public: void ImplementCalculations(string EmployeeName, double hours, double wage); void DisplayEmployInformation(void); void Addsomethingup (CEmployee, CEmployee, CEmployee); string EmployeeName ; int hours ; int overtime_hours ; int iTotal_hours ; int iTotal_OvertimeHours ; float wage ; float basepay ; float overtime_pay ; float overtime_extra ; float iTotal_salaries ; float iIndividualSalary ; }; int main() { system("cls"); cout << "Welcome to the Employee Pay Center"; /* Use this section to define your objects.

You will do this for each of the three employees or objects. The format for this step is the following: [(object name.function name(objectname.name, objectname.hours, objectname.wage)] ; */ /* This section you will send all three objects to a function that will add up the the following information: - Total Employee Salaries - Total Employee Hours - Total Overtime Hours The format for this function is the following: - Define a new object. - Implement function call [objectname.functionname(object name 1, object name 2, object name 3)] /* } //End of Main Function void CEmployee::ImplementCalculations (string EmployeeName, double hours, double wage){ //Initialize overtime variables overtime_hours=0; overtime_pay=0; overtime_extra=0; if (hours > 40) { /* This section is for the basic calculations for calculating overtime pay. - base pay = 40 hours times the hourly wage - overtime hours = hours worked – 40 - overtime pay = hourly wage * 1.5 - overtime extra pay over 40 = overtime hours * overtime pay - salary = overtime money over 40 hours + your base pay */ /* Implement function call to output the employee information.

• TFS 2010 SDK: Connecting to TFS 2010 Programmatically&ndash;Part 1

  - by Tarun Arora

  Technorati Tags: Team Foundation Server 2010,TFS 2010 SDK,TFS API,TFS Programming,TFS ALM   Download Working Demo Great! You have reached that point where you would like to extend TFS 2010. The first step is to connect to TFS programmatically. 1. Download TFS 2010 SDK => http://visualstudiogallery.msdn.microsoft.com/25622469-19d8-4959-8e5c-4025d1c9183d?SRC=VSIDE 2. Alternatively you can also download this from the visual studio extension manager 3. Create a new Windows Forms Application project and add reference to TFS Common and client dlls Note - If Microsoft.TeamFoundation.Client and Microsoft.TeamFoundation.Common do not appear on the .NET tab of the References dialog box, use the Browse tab to add the assemblies. You can find them at %ProgramFiles%\Microsoft Visual Studio 10.0\Common7\IDE\ReferenceAssemblies\v2.0. using Microsoft.TeamFoundation.Client; using Microsoft.TeamFoundation.Framework.Client; using Microsoft.TeamFoundation.Framework.Common;   4. There are several ways to connect to TFS, the two classes of interest are, Option 1 – Class – TfsTeamProjectCollectionClass namespace Microsoft.TeamFoundation.Client { public class TfsTeamProjectCollection : TfsConnection { public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection); public TfsTeamProjectCollection(Uri uri); public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection, IdentityDescriptor identityToImpersonate); public TfsTeamProjectCollection(Uri uri, ICredentials credentials); public TfsTeamProjectCollection(Uri uri, ICredentialsProvider credentialsProvider); public TfsTeamProjectCollection(Uri uri, IdentityDescriptor identityToImpersonate); public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsTeamProjectCollection(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public TfsTeamProjectCollection(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public override CatalogNode CatalogNode { get; } public TfsConfigurationServer ConfigurationServer { get; internal set; } public override string Name { get; } public static Uri GetFullyQualifiedUriForName(string name); protected override object GetServiceInstance(Type serviceType, object serviceInstance); protected override object InitializeTeamFoundationObject(string fullName, object instance); } } Option 2 – Class – TfsConfigurationServer namespace Microsoft.TeamFoundation.Client { public class TfsConfigurationServer : TfsConnection { public TfsConfigurationServer(RegisteredConfigurationServer application); public TfsConfigurationServer(Uri uri); public TfsConfigurationServer(RegisteredConfigurationServer application, IdentityDescriptor identityToImpersonate); public TfsConfigurationServer(Uri uri, ICredentials credentials); public TfsConfigurationServer(Uri uri, ICredentialsProvider credentialsProvider); public TfsConfigurationServer(Uri uri, IdentityDescriptor identityToImpersonate); public TfsConfigurationServer(RegisteredConfigurationServer application, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsConfigurationServer(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsConfigurationServer(RegisteredConfigurationServer application, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public TfsConfigurationServer(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public override CatalogNode CatalogNode { get; } public override string Name { get; } protected override object GetServiceInstance(Type serviceType, object serviceInstance); public TfsTeamProjectCollection GetTeamProjectCollection(Guid collectionId); protected override object InitializeTeamFoundationObject(string fullName, object instance); } }   Note – The TeamFoundationServer class is obsolete. Use the TfsTeamProjectCollection or TfsConfigurationServer classes to talk to a 2010 Team Foundation Server. In order to talk to a 2005 or 2008 Team Foundation Server use the TfsTeamProjectCollection class. 5. Sample code for programmatically connecting to TFS 2010 using the TFS 2010 API How do i know what the URI of my TFS server is, Note – You need to be have Team Project Collection view details permission in order to connect, expect to receive an authorization failure message if you do not have sufficient permissions. Case 1: Connect by Uri string _myUri = @"https://tfs.codeplex.com:443/tfs/tfs30"; TfsConfigurationServer configurationServer = TfsConfigurationServerFactory.GetConfigurationServer(new Uri(_myUri)); Case 2: Connect by Uri, prompt for credentials string _myUri = @"https://tfs.codeplex.com:443/tfs/tfs30"; TfsConfigurationServer configurationServer = TfsConfigurationServerFactory.GetConfigurationServer(new Uri(_myUri), new UICredentialsProvider()); configurationServer.EnsureAuthenticated(); Case 3: Connect by Uri, custom credentials In order to use this method of connectivity you need to implement the interface ICredentailsProvider public class ConnectByImplementingCredentialsProvider : ICredentialsProvider { public ICredentials GetCredentials(Uri uri, ICredentials iCredentials) { return new NetworkCredential("UserName", "Password", "Domain"); } public void NotifyCredentialsAuthenticated(Uri uri) { throw new ApplicationException("Unable to authenticate"); } } And now consume the implementation of the interface, string _myUri = @"https://tfs.codeplex.com:443/tfs/tfs30"; ConnectByImplementingCredentialsProvider connect = new ConnectByImplementingCredentialsProvider(); ICredentials iCred = new NetworkCredential("UserName", "Password", "Domain"); connect.GetCredentials(new Uri(_myUri), iCred); TfsConfigurationServer configurationServer = TfsConfigurationServerFactory.GetConfigurationServer(new Uri(_myUri), connect); configurationServer.EnsureAuthenticated();   6. Programmatically query TFS 2010 using the TFS SDK for all Team Project Collections and retrieve all Team Projects and output the display name and description of each team project. CatalogNode catalogNode = configurationServer.CatalogNode; ReadOnlyCollection<CatalogNode> tpcNodes = catalogNode.QueryChildren( new Guid[] { CatalogResourceTypes.ProjectCollection }, false, CatalogQueryOptions.None); // tpc = Team Project Collection foreach (CatalogNode tpcNode in tpcNodes) { Guid tpcId = new Guid(tpcNode.Resource.Properties["InstanceId"]); TfsTeamProjectCollection tpc = configurationServer.GetTeamProjectCollection(tpcId); // Get catalog of tp = 'Team Projects' for the tpc = 'Team Project Collection' var tpNodes = tpcNode.QueryChildren( new Guid[] { CatalogResourceTypes.TeamProject }, false, CatalogQueryOptions.None); foreach (var p in tpNodes) { Debug.Write(Environment.NewLine + " Team Project : " + p.Resource.DisplayName + " - " + p.Resource.Description + Environment.NewLine); } }   Output   You can download a working demo that uses TFS SDK 2010 to programmatically connect to TFS 2010.
