  • Class Members Over Exports

    - by VirusEcks
    When Using DLLs or Code-injecting to be Specific this is an example class only intended for explaining class test { int newint1; char newchararray[512]; void (*newfunction1)( int newarg1 ); int newfunction2( bool newarg1, char newarg2 ) { return newint1; } } mynewclass1; that covers most common elements that's included in classes now when exporting this function to another DLL or application and missed an element of those, either data member or function member, private or public what happens or changed their order ? and if each function is assigned it's value when Code-Injecting like mynewclass1.newfunction1 = (void *)(newexportedfunction); what's the happens in this case, if members of the class are pointers that are assigned after class construction and then missed one member or changed their order ?

  • C#, working with files, "Unauthorized Access"?

    - by Rob
    Hi, I'm learning about opening and saving files with C# and it seems that vista won't let my program save to a file on the root of C:\ , unless I run it in administrator mode. Any ideas how to allow my program to play around with whatever files it wants? Thanks! string name; private void button2_Click(object sender, EventArgs e) ///// OPEN ///// { if (openFileDialog1.ShowDialog() == DialogResult.OK) { name = openFileDialog1.FileName; textBox1.Clear(); textBox1.Text = File.ReadAllText(name); textBox2.Text = name; } } private void button1_Click(object sender, EventArgs e) ///// SAVE ///// { File.WriteAllText(name, textBox1.Text); }

  • Volatile keyword

    - by Tiyoal
    Say I have two threads and an object. One thread assigns the object: public void assign(MyObject o) { myObject = o; } Another thread uses the object: public void use() { myObject.use(); } Does the variable myObject have to be declared as volatile? I am trying to understand when to use volatile and when not, and this is puzzling me. Is it possible that the second thread keeps a reference to an old object in its local memory cache? If not, why not? Thanks a lot.

  • Pass the current state of a function into another function in C/C++

    - by sand
    Is there a way to pass the current state of a function into another function in C/C++? I mean all the parameters and local variables by current state. For example: void funcA (int a, int b) { char c; int d, e; // Do something with the variables. // ... funcB(); // Do something more. } void funcB() { // funcB() should be able to access variables a,b,c,d & e // and any change in these variables reflect into funcA(). } The code is in bad shape if there is a need for funcB() kind of functions. But can it be achieved? This can help if someone is starting to re-factor a long method with multiple parameters.

  • Is it bad practice to declare an array mid-function...

    - by Maximus
    In C, which would be more proper... void MyFunction() { int* array; int size; //do a bunch of stuff size = 10; array = (int*)(sizeof(int)*size); //do more stuff... //no longer need array... free(array); } Or is something like this okay? void MyFunction() { int size; //do a bunch of stuff size = 10; array[size]; //do more stuff... } The malloc uses the heap instead of the stack, so I suppose if you know size is going to be very large you'd want to malloc... but if you're quite certain size will be small enough, would the second method be reasonable?

  • Send Ctrl+Up to a window

    - by dutt
    I'm trying to send messages to a window that says Ctrl and Up-arrow has been pressed. I've got the basics down, I can send presses of the space key that registeres fine. But I can't seem to get the ctrl+up working. chosen code snippets: [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)] static extern IntPtr SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam); Now this works fine for sending Space: public static void SendKeyPress(IntPtr handle, VKeys key) { SendMessage(handle, (int) WMessages.WM_KEYDOWN, (int) key, 0); SendMessage(handle, (int)WMessages.WM_KEYUP, (int)key, 0); } But this doesn't work for sending Ctrl+Up: public static void SendKeyPress(IntPtr handle, VKeys key, bool control) { SendMessage(handle, (int) WMessages.WM_KEYDOWN, (int) key, 0); SendMessage(handle, (int) WMessages.WM_KEYDOWN, (int)VKeys.VK_CONTROL, 0); SendMessage(handle, (int)WMessages.WM_KEYUP, (int)key, 0); SendMessage(handle, (int)WMessages.WM_KEYUP, (int)VKeys.VK_CONTROL, 0); } What am I missing?

  • Parse boolean values in strings for use with Function.apply

    - by as3cmdline
    I'm using String.split to parse a command line string into an array of strings. The result is then used to call a function using the Function.apply API. If apply(null, ["17"]) is called with this function: static function test(foo:int):void { trace(foo, typeof(foo)); } it works as expected (output: 17 number). However, calling apply(null, ["false"]) or apply(null, ["0"]) with this function: static function test(foo:Boolean):void { trace(foo, typeof(foo)); } does not work (expected output: false Boolean; actual output: true Boolean). Is there a way to make it recognize "true" and "false" (or anything else) as Boolean values, just like it does with numerical strings? Ideally "true" and "false" should also remain valid string values.

  • Java array of arry [matrix] of an integer partition with fixed term

    - by user335209
    Hello, for my study purpose I need to build an array of array filled with the partitions of an integer with fixed term. That is given an integer, suppose 10 and given the fixed number of terms, suppose 5 I need to populate an array like this 10 0 0 0 0 9 0 0 0 1 8 0 0 0 2 7 0 0 0 3 ............ 9 0 0 1 0 8 0 0 1 1 ............. 7 0 1 1 0 6 0 1 1 1 ............ ........... 0 6 1 1 1 ............. 0 0 0 0 10 am pretty new to Java and am getting confused with all the for loops. Right now my code can do the partition of the integer but unfortunately it is not with fixed term public class Partition { private static int[] riga; private static void printPartition(int[] p, int n) { for (int i= 0; i < n; i++) System.out.print(p[i]+" "); System.out.println(); } private static void partition(int[] p, int n, int m, int i) { if (n == 0) printPartition(p, i); else for (int k= m; k > 0; k--) { p[i]= k; partition(p, n-k, n-k, i+1); } } public static void main(String[] args) { riga = new int[6]; for(int i = 0; i<riga.length; i++){ riga[i] = 0; } partition(riga, 6, 1, 0); } } the output I get it from is like this: 1 5 1 4 1 1 3 2 1 3 1 1 1 2 3 1 2 2 1 1 2 1 2 1 2 1 1 1 what i'm actually trying to understand how to proceed is to have it with a fixed terms which would be the columns of my array. So, am stuck with trying to get a way to make it less dynamic. Any help?

  • LoadContent does not work in my components

    - by drozzy
    For some reason the LoadContent method does not get called in my Components. For example I have Game class in which I do: //Game.cs protected override void LoadContent() { editor = new Editor(...); Components.Add(editor); } //Editor.cs public class Editor : DrawableGameComponent{ Game game; public Editor(Game game, ...):base(game){ this.game = game; } //THIS method never gets called! protected override void LoadContent() { background = game.Content.Load<Texture2D>("background"); base.LoadContent(); } } Any tips? EDIT: When you keep in mind the order of Initialize and LoadContent everything works out fine!

  • Unit tests logged (or run) multiple times

    - by HeavyWave
    I have this simple test: protected readonly ILog logger = LogManager.GetLogger(MethodBase.GetCurrentMethod().ReflectedType); private static int count = 0; [Test] public void TestConfiguredSuccessfully() { logger.Debug("in test method" + count++); } log4net is set up like this: [TestFixtureSetUp] public void SetUp() { log4net.Config.BasicConfigurator.Configure(); } The problem is, that if I run this test in nUnit once, I get the output (as expected): 1742 [TestRunnerThread] DEBUG Tests.TestSomthing (null) - in test method0 But if I press RUN in nUnit.exe again (or more) I get the following: 1742 [TestRunnerThread] DEBUG Tests.TestSomthing (null) - in test method1 1742 [TestRunnerThread] DEBUG Tests.TestSomthing (null) - in test method1 And so on (if I run it 5 times, I'll get 5 repeating lines). Now, if I run the same test alone from reSharper the output is fine and does not repeat. However, if I run this test along side 2 other tests in the same class, the output is repeated three times. I am totally confused. What the hell is going on here?

  • How to connect Model through Controller to View using bindings?

    - by Paperflyer
    I have an NSTextField in my view. Its value is bound to an NSNumber *number in my controller. The controller simply calls through to the model (value) to get the appropriate value. // In the controller - (NSNumber *)number { return [NSNumber numberWithFloat:[model value]]; } - (void)setNumber:(NSNumber *)aNumber { [model setValue:[aNumber floatValue]]; } This is fine, only the controller is not notified of model changes and thus, changing the value in the model does not update the NSTextField. The only other option I can think of is to have the model notify the controller and the controller manually update the view through an Outlet. But this circumvents the binding. // In the model, after value change [[NSNotificationCenter defaultCenter] postNotificationName:@"ValueChanged" object:self]; // In the controller, after being notified - (void)updateView:(NSNotification *)aNotification { [myTextField setFloatValue:[model value]]; } Is there a better, binding-aware way to implement this communication?

  • Add button to a layout programmatically

    - by mmmbaileys
    I'm having trouble adding a button to a layout that I've created in XML. Here's what I want to achieve: //some class else { startActivity(new Intent(StatisticsScreen.this, ScreenTemperature.class)); } //// //ScreenTemperatureClass @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //this is where I call another class that //displays a nice graph setContentView(new GraphTemperature(getApplicationContext())); } I want to add a Button to this new screen so that it'll appear below the graph. I've tried creating a LinearLayout view, then create a Button and add it to this view but I just get NullPointerExceptions.. Any help would be appreciated. Thanks EDIT#1 Here's what I've tried using that created a NullPointerException and 'force close': Button buybutton; LinearLayout layout; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(new GraphTemperature(getApplicationContext())); layout = (LinearLayout) findViewById(R.id.statsviewlayout); Button buyButton = new Button(this); buyButton.setText(R.string.button_back); buyButton.setLayoutParams(new LayoutParams( ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); layout.addView(buyButton); } And here's the logcat error: ERROR/AndroidRuntime(293): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.weatherapp/com.weatherapp.ScreenTemperature}: java.lang.NullPointerException ERROR/AndroidRuntime(293): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2663) ERROR/AndroidRuntime(293): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2679) ERROR/AndroidRuntime(293): at android.app.ActivityThread.access$2300(ActivityThread.java:125) ERROR/AndroidRuntime(293): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2033) theres abviously more lines to do with this error in logcat, not sure if you want it? EDIT#2 So i tried bhups method: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); GraphTemperature GT = new GraphTemperature(getApplicationContext()); layout = (LinearLayout) findViewById(R.id.statsviewlayout); Button buyButton = new Button(this); buyButton.setText(R.string.button_back); buyButton.setLayoutParams(new LayoutParams( ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); layout.addView(GT); // line 27 layout.addView(buyButton); setContentView(layout); } This method produced the same logcat error as above, NullPointerException, indicating it was something to do with line no. 27 which is the layout.addView line of code. Any ideas? Thanks again
