• JNI: dll function works ok in C++ main, but not with dll wrapper

  - by Joseph Lim

  I have an a.dll (not modifiable as i do not have the source) with a function bool openPort(DWORD mem).I wrote a c++ main, loaded this dll using LoadLibrary, and the function works well.It returns true. Now, I need to call this function from Java via JNI. I wrote another b.dll with a function like so JNIEXPORT void JNICALL Java_MyClass_openPortFunc (JNIEnv *env, jobject obj, jint pMemPhy) { hInstLibrary = LoadLibrary("a.dll"); typedef bool (*openPort)(DWORD); openPort _openPort; _openPort = (openPort)GetProcAddress(hInstLibrary, "openPort"); DWORD memAddr = 0xda000; if(_openPort(memAddr)){ cout << "ok" << endl; }else{ cout << "failed " << endl; } } This however, causes the openPort to return false despite using the same parameters. I hope someone can advise me. Thank you. :)

• Pass temporary object to function that takes pointer

  - by Happy Mittal

  I tried following code : #include<iostream> #include<string> using namespace std; string f1(string s) { return s="f1 called"; } void f2(string *s) { cout<<*s<<endl; } int main() { string str; f2(&f1(str)); } But this code doesn't compile. What I think is : f1 returns by value so it creates temporary, of which I am taking address and passing to f2. Now Please explain me where I am thinking wrong?

• Flash AS3: automate property assignment to new instance from arguments in constructor

  - by matt lohkamp

  I like finding out about tricky new ways to do things. Let's say you've got a class with a property that gets set to the value of an argument in the constructor, like so: package{ public class SomeClass{ private var someProperty:*; public function SomeClass(_someProperty:*):void{ someProperty = _someProperty; } } } That's not exactly a hassle. But imagine you've got... I don't know, five properties. Ten properties, maybe. Rather then writing out each individual assignment, line by line, isn't there a way to loop through the constructor's arguments and set the value of each corresponding property on the new instance accordingly? I don't think that the ...rest or arguments objects will work, since they only keep an enumerated list of the arguments, not the argument names - I'm thinking something like this would be better: for(var propertyName:String in argsAsAssocArray){this[propertyName] = argsAsAssocArray[propertyName];} ... does something like this exist?

• Programatically Add a AnnotationSessionFactoryBean

  - by user146714

  Hi, I have a class that implements BeanDefinitionRegistryPostProcessor. I am trying to add an AnnotationSessionFactoryBean to my Spring Context in either postProcessBeanFactory or postProcessBeanDefinitionRegistry. I need to do this programatically so that I can configure the object at runtime. I am trying to do: @Override public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry bdr) throws BeansException { RootBeanDefinition bd = new RootBeanDefinition( AnnotationSessionFactoryBean.class); // fails here.. can not cast AnnotationSessionFactoryBean asfb = (AnnotationSessionFactoryBean)bd; bdr.registerBeanDefinition("sessionFactory", asfb); thanks for your help --updated with solution: had to do a: GenericBeanDefinition bd = new GenericBeanDefinition(); bd.setBeanClass(AnnotationSessionFactoryBean.class); bd.getPropertyValues().add("dataSource", dataSource); bdr.registerBeanDefinition("sessionFactory", bd);

• How can I fit an Image into another imageview

  - by user1597833

  I have an imageview with a default image already set from the xml, and I want to change it's image pragmatically so that the new image will scale to the previous image size, both of the images are rounded. I have tried setting the scaleType attribute to different values before setting the new image but it didn't work. This is the xml: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <ImageView android:id="@+id/up_right_circle_firstiv" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:scaleType="fitXY" android:src="@drawable/circle_medium_up" /> This is the activity code: public class MainActivity extends Activity { ImageView middleCircle; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); middleCircle = (ImageView) findViewById(R.id.up_right_circle_firstiv); middleCircle.setImageResource(R.drawable.round_pic_one); } } Inside the activity. I have uploaded the screenshots: http://imgur.com/OM79T http://imgur.com/G7y3Q

• How to pass around event as parameter in c#

  - by Jerry Liu

  Am writing unit test for a multi-threading application, where I need to wait until a specific event triggered so that I know the asyn operation is done. E.g. When I call repository.add(something), I wait for event AfterChange before doing any assertion. So I write a util function to do that. public static void SyncAction(EventHandler event_, Action action_) { var signal = new object(); EventHandler callback = null; callback = new EventHandler((s, e) => { lock (signal) { Monitor.Pulse(signal); } event_ -= callback; }); event_ += callback; lock (signal) { action_(); Assert.IsTrue(Monitor.Wait(signal, 10000)); } } However, the compiler prevents from passing event out of the class. Is there a way to achieve that?

• Animation of UINavigationController's UIToolbar

  - by Michael Waterfall

  When presenting a view controller that has toolbar items, is it possible for the toolbar to slide in with the view controller (i.e. slide in from the right) as opposed to it sliding from the bottom? In the view controller that is being presented, I've got the toolbar being shown within the -viewWillAppear: method, but the toolbar is being slid up from the bottom of the screen as opposed to it looking like it belongs to the view controller. - (void)viewWillAppear:(BOOL)animated { [self.navigationController setToolbarHidden:NO animated:YES]; ... }

• Trouble assigning a tr1::shared_ptr

  - by Max

  I've got a class that has a tr1::shared_ptr as a member, like so: class Foo { std::tr1::shared_ptr<TCODBsp> bsp; void Bar(); } In member function Bar, I try to assign it like this: bsp = newTCODBsp(x,y,w,h); g++ then gives me this error no match for ‘operator=’ in ‘((yarl::mapGen::MapGenerator*)this)->yarl::mapGen::MapGenerator::bsp = (operator new(40u), (<statement>, ((TCODBsp*)<anonymous>)))’ /usr/include/c++/4.4/tr1/shared_ptr.h:834: note: candidates are: std::tr1::shared_ptr<TCODBsp>& std::tr1::shared_ptr<TCODBsp>::operator=(const std::tr1::shared_ptr<TCODBsp>&) in my code, Foo is actually yarl::mapGen::MapGenerator. What am I doing wrong?

• Address calling class

  - by Samuel

  I have an abstract class Moveable with the method abstract void move() which is extended by the class Bullet and the abstract class Character, and Character is extended by the class Survivor and the class Zombie. In Survivor and Bullet the move() method doesnt require any parameters while in the class Zombie the move() method depends on the actual position of the survivor. The survivor and multiple zombies are created in the class Gui. I wanted to access the survivor in Zombie - what's the best way of doing this? In Gui i wrote a method getSurvivor() but i don't see how to access this method in Zombie? I am aware that as a workaround i could just pass a [Survivor survivor] as parameter in move() and ignore it in Bullet and Survivor, but that feels so ... bad practice.

• Forcing a templated object to construct from a pointer

  - by SalamiArmi

  I have a fictional class: template<typename T> class demonstration { public: demonstration(){} ... T *m_data; } At some point in the program's execution, I want to set m_data to a big block of allocated memory and construct an object T there. At the moment, I've been using this code: void construct() { *m_data = T(); } Which I've now realised is probably not the best idea... wont work under certain cirumstances, if T has a private assignment operator for example. Is there a normal/better way to do what I'm attempting here?

• How do I clear the contents of a file using c?

  - by Eddy

  I'm writing some code so that at each iteration of a for loop it runs a functions which writes data into a file, like this: int main() { int i; /* Write data to file 100 times */ for(i = 0; i < 100; i++) writedata(); return 0; } void writedata() { /* Create file for displaying output */ FILE *data; data = fopen("output.dat", "a"); /* do other stuff */ ... } How do I get it so that when I run the program it will delete the file contents at the beginning of the program, but after that it will append data to the file? I know that using the "w" identifier in fopen() will open a new file that's empty, but I want to be able to 'append' data to the file each time it goes through the 'writedata()' function, hence the use of the "a" identifier.

• Why do i get segfault at the end of the application after everything's been done properly ?

Why ?

• C# COM+ component isn't getting the constructor string

  - by Kyle W

  I've created a COM+ component in C# with a strong name, COM Visible, ProgId, etc... I've then registered the assembly with regasm, and imported it into the COM+ Applications in Component Services. It runs just fine, and loads up the DLL, except that the constructor string that is passed in is always empty. The method signature is protected override void Construct(string constructString), and it is being called before the method on the actual component. In the component details in COM+ Applications, the constructor string is checked and a value is entered. Any help is appreciated.

• ASP.Net - Gridview row selection and effects

  I'm using the following code in attempt to allow the user to select a gridview row by clicking anywhere on the row (plus mouse over and out) effects. The code doesn't seem to be applied on rowdatabound and I can't break into the event. (It is wired). The control is in a usercontrol, that lives in a content page, which has a masterpage. protected void gvOrderTypes_RowDataBound(object sender, GridViewRowEventArgs e) { GridView gvOrdTypes = (GridView)sender; //check the item being bound is actually a DataRow, if it is, //wire up the required html events and attach the relevant JavaScripts if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes["onmouseover"] = "javascript:setMouseOverColor(this);"; e.Row.Attributes["onmouseout"] = "javascript:setMouseOutColor(this);"; e.Row.Attributes["onclick"] = Page.ClientScript.GetPostBackClientHyperlink(gvOrdTypes, "Select$" + e.Row.RowIndex); } }

• NavigationController does not set view properties correctly when pushed

  I have a UITabBarControllerDelegate that pushes a new view controller when a certain tab is pressed: - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { MyView* myView = [[[MyView alloc] initWithNibName:@"MyView" bundle:nil]autorelease]; if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; [self.navigationController myView animated:YES]; } } However, if I change my code to set the tabbar's selected view controller to myView everything works, but I don't get my navigation bar: if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; self.tabBarController.selectedViewController = myView; } How can I set the reloadFriends property in MyView and have the navigation bar at the top?

• debugfs_create_file doesn't create file

  - by bala1486

  Hello, I am trying to create a debugfs file using the debugfs_create_file(...). I have written a sample code for this. static int __init mmapexample_module_init(void) { file1 = debugfs_create_file("mmap_example", 0644, NULL, NULL, &my_fops)\ ; printk(KERN_ALERT "Hello, World\n"); if(file1==NULL) { printk(KERN_ALERT "Error occured\n"); } if(file1==-ENODEV) { printk(KERN_ALERT "ENODEV occured\n"); } return 0; } When i ran insmod i could get the Hello, World message but no the error message. So i think the debugfs_create_file worked fine. However i couldn't find any file in /sys/kernel/debug. The folder is there but it is empty. Can anyone help me with this? Thank you... Thanks, Bala
