  I'd like to try the wisdom of the crowds..because i'm frustrated right now. Thanks in advance.

• C# equivalent of recv?

  - by mlh

  Hello, I have a portion of C code that I am trying to port over to C#. In my C code, I create a socket and then issue a receive command. The receive command is void receive(mysocket, char * command_buffer) { recv(mysocket, command_buffer, COMMAND_BUFFER_SIZE, 0); } now, the command buffer is returned with new values including command_buffer[8] being a pointer to a string. I'm really confused as to how to do this in C# because C# Read() command specifically takes in bytes and not char. The important part is that I get the pointer to the string. Any ideas?

• Constructors in Inner classes (implementing Interfaces)

  - by thepandaatemyface

  Hi, How would I go about writing a constructor for an inner class which is implementing an interface? I know I could make a whole new class, but I figure there's got to be a way to do something along the line of this: JButton b = new JButton(new AbstractAction() { public AbstractAction() { super("This is a button"); } public void actionPerformed(ActionEvent e) { System.out.println("button clicked"); } }); When I enter this it doesn't recognize the AbstractAction method as a constructor (compiler asks for return type). Anyone have an idea? Thanks

• Adding characters to string

  - by Jamza

  I am currently trying to build a very basic serial shell with my arduino. I am able to get an output from the device using Serial.read() and can get the character it has outputted, but I cannot work out how to then add that character to a longer to form the full command. I tried the logical thing but it doesn't work: char Command[]; void loop(){ if(Serial.available() > 0){ int clinput = Serial.read(); Command = Command + char(clinput); } Can anybody help? Thank You.

• Why does Generic class signature requires specifying new() if type T needs instantiation ?

  - by this. __curious_geek

  I'm writing a Generic class as following. public class Foo<T> : where T : Bar, new() { public void MethodInFoo() { T _t = new T(); } } As you can see the object(_t) of type T is instantiated at run-time. To support instantiation of generic type T, language forces me to put new() in the class signature. I'd agree to this if Bar is an abstract class but why does it need to be so if Bar standard non-abstract class with public parameter-less constructor. compiler prompts following message if new() is not found. Cannot create an instance of the variable type 'T' because it does not have the new() constraint

• Creating a button on a View from a second View

  - by BigJoke

  Hi, I have this app I'm working on, which on a second view asks (textfield) the name for a button to be created on first view. After specifying the name and pressing OK button, the first view pops up (as demanded) but there's no new button, although created indeed. Can I use the following code in a second view method, to "refresh" the first view before presenting itself. What's wrong with this code? Any other approach? Thank you. -(void)initWithView:(View1Controller *)aSuperview { theSuperview = aSuperview; } - (IBAction)itemNameButton { ... CGRect rectang; rectang = CGRectMake(0, 0, 320, 460);// just in case [theSuperview.view setNeedsDisplayInRect:rectang]; ... }

• EXC_BAD_ACCESS iPhone Development

  - by gkres121

  Sorry, this could be a simple fix, as I am new to iPhone Development. In my Delegate, after pressing the create profile button, the create profile view is pushed: -(void) createProfile_clicked:(id)sender { AddNewProfile *create = [[AddNewProfile alloc] init]; [self.window addSubview:create.view]; [self invisibleCreateProfileBar]; AddNewProfile *controller = [[AddNewProfile alloc] initWithNibName:@"AddNewProfile" bundle:[NSBundle mainBundle]]; [ self.navigationController pushViewController:controller animated:YES ]; currentController=controller; } Then in the AddNewProfile.m: - (IBAction)backgroundTap:(id)sender { if([nameField isFirstResponder]){ [nameField resignFirstResponder]; } if([ageField isFirstResponder]){ [ageField resignFirstResponder]; } if([doctorNameField isFirstResponder]){ [doctorNameField isFirstResponder]; } if([doctorNumberField isFirstResponder]){ [doctorNumberField resignFirstResponder]; } } This leads to a exc_bad_access error every time the FirstResponder is ever messed with, with any of my controls. I can select a control(text box), but once I click out of one, it crashes. Any help would be greatly appreciated.

• C# Object Array CopyTo links both arrays' values?

  - by Dutchie432

  Okay, I have what I think is a simple question.. or just a case of me being a C# beginner. I have an array of custom objects (clsScriptItem) that I am populating from a database. Once the items are loaded, I want to back them up to "backup" array so I can revert the information back after changing the main array. However, when I use CopyTo to copy the array and then alter the original array, the backup array is also being altered... I though CopyTo merely copied values + structure from one array to another. private void backupItems() { lastSavedItems = new clsScriptItem[items.Length]; items.CopyTo(lastSavedItems, 0); //items[0].nexts[0] is 2 //lastSavedItems[0].nexts[0] is 2 items[0].nexts[0] = "-1"; //items[0].nexts[0] is -1 //lastSavedItems[0].nexts[0] is also -1 } How do I backup this data without having the two arrays be 'linked'??

• How to stop a MFC/win32 control re-painting

  - by John

  I have a CRichEditCtrl, and an algorithm works on its contents in-place, iterating through the contents and making changes. This seems to cause it to re-paaint every time, which causes flickering and a noticeable time to complete the operation, especially if the control starts scrolling. I wondered if there's a neat way for me to stop it repainting for a period. It's actually a custom subclass of CRichEditCtrl in use so I was thinking something like: void MyCustomEditCtrl::DoAlgorithm() { enableRepaint(false); ... //to the actual work ... enableRepaint(true); } What's the neatest approach? A custom on-paint handler which does nothing when an operation is in progress? Or can repainting actually be disabled?

  Hi I would like to know if there is any way in Java to reduce the size of an image (use any kind of compression) that was loaded as a BufferedImage and is going to be saved as an PNG. Maybe some sort of png imagewriteparam? I didnt find anything helpful so im stuck. heres a sample how the image is loaded and saved public static BufferedImage load(String imageUrl) { Image image = new ImageIcon(imageUrl).getImage(); bufferedImage = new BufferedImage(image.getWidth(null), image.getHeight(null), BufferedImage.TYPE_INT_ARGB); Graphics2D g2D = bufferedImage.createGraphics(); g2D.drawImage(image, 0, 0, null); return bufferedImage; } public static void storeImageAsPng(BufferedImage image, String imageUrl) throws IOException { ImageIO.write(image, "png", new File(imageUrl)); }

• Making sure an 'int' is bound on sqlite

  - by iphone_developer

  I have a method called like this... -(void)dbUpdate:(int)forId { Which contains this sqlite to bind and update a database. sqlite3_bind_int(UPDATE_ACCOUNT, 3, forId); When I run the query, it doesn't give me an error, but it doesn't update the database either. If I change this line of code... sqlite3_bind_int(UPDATE_ACCOUNT, 3, forId); manually, to... sqlite3_bind_int(UPDATE_ACCOUNT, 3, 6); the query runs 100% fine, as expected. Changing the variable to an actual integer proves to me that the variable 'forId' isn't being passed or bound to the query properly. What am I doing wrong? How is the best way to pass an Integer (and make sure it is an Integer) into an sqlite bind? Cheers,
