• Is there a view for inputing integers in Android?

  - by J. Pablo Fernández

  I'm looking for something like the individual parts of the date picker dialog. A view that allows you to input integers (and only integers) that you can limit (between 1 and 10 for example), where you can use the keyboard or the arrows in the view itself. Does it exists? It is for a dialog. A ready-made dialog to request an integer would also help.

• At What point should you understand pointers?

  - by Vaccano

  I asked a question like this in an interview for a entry level programmer: var instance1 = new myObject{Value = "hello"} var instance2 = instance1; instance1.Value = "bye"; Console.WriteLine(instance1.Value); Console.WriteLine(instance2.Value); The applicant responded with "hello", "bye" as the output. Some of my co-workers said that pointers are not that important anymore or that this question is not a real judge of ability. Are they right?

• Command prompt in debug mode for Eclipse? (OpenCV + Eclipse + Win7)

  - by Tony

  I am a beginner for Eclipse. I now have Eclipse C/C++ IDE with OpenCV library running on Windows 7. So far it works after spending hours trying to get it running. But then I realize that Eclipse does not pop up a command prompt as VS2010 does while debugging. And moreover Eclipse's debug mode is just stuck in there and refuse to output anything. But if the code doesn't involve the OpenCV things it works again. Below is the code I use for testing. It captures images from webcam and output it to the screen. The infinite loop (until you press 'q') makes sure it constantly grabs new inputs from the camera. I browsed through the workspace and run the exe just compiled and it worked flawlessly. So I don't think there's anything wrong in the code (it's an example code anyway In brief, can I just pop up a command prompt window in debug mode? And why is Eclipse console stuck when the code involves some OpenCV functions? #include <stdio.h> #include <stdlib.h> #include <tchar.h> #include <cv.h> #include <cxcore.h> #include <highgui.h> #include <iostream> int _tmain(int argc, _TCHAR* argv[]) { CvCapture *capture = 0; IplImage *frame = 0; int key = 0; /* initialize camera */ capture = cvCaptureFromCAM( 0 ); /* always check */ if ( !capture ) { printf("Cannot open initialize webcam!\n"); return 1; } /* create a window for the video */ cvNamedWindow( "result", CV_WINDOW_AUTOSIZE ); while( key != 'q' ) { /* get a frame */ frame = cvQueryFrame( capture ); /* always check */ if( !frame ) break; /* display current frame */ cvShowImage( "result", frame ); /* exit if user press 'q' */ key = cvWaitKey( 1 ); } /* free memory */ cvDestroyWindow( "result" ); cvReleaseCapture( &capture ); return 0; }

• Rendering a View without a Master Page

  - by Fauxide

  Heya, I'm fetching a page using ajax (jquery) and appending certain data to the Requests query string to let the server know it shouldn't render the entire Page, just the view in question to the output buffer. I'm having no luck though, I can detect when the page needs to be rendered partially, but everything I've tried so far (including stuff like return PartialView()) isn't working. Any ideas? Thanks in advance.

• Setting end-of-line character for puts

  - by Dom De Felice

  I have an array of entries I would like to print. Being arr the array, I used just to write: puts arr Then I needed to use the DOS format end-of-line: \r\n, so I wrote: arr.each { |e| print "#{e}\r\n" } This works correctly, but I would like to know if there is a way to specify what end-of-line format to use so that I could write something like: $eol = "\r\n" puts arr UPDATE I know that puts will use the correct line-endings depending on the platform it is run on, but I need this because I will write the output to a file.

• How do I get this validationTextBox to focus?

  - by Anurag Chaudhury

  After performing an ajax request if the input in the form was wrong I am trying to get this validatationTextBox to be focussed on and display an indicator message showing the problem. The code is: dijit.byId("passwordField").focusNode.focus() The form element is as mentioned a validationTextBox. The matter that is confusing me even further is that before in dojo 1.5, this piece of code was simply dijit.byId("passwordField").focus() and this worked fine. How can I fix this?

• simple interview question

  - by calvin

  Input integer array: a[8] = { a1, a2, a3, a4, b1, b2, b3, b4 } Output array: a[8] = { a1, b1, a2, b2, a3, b3, a4, b4 } Forget all corner cases, make sure your solution works for any int array of size 2n. You can use one or two temp variables for looping or anything, but you shouldn't use any temp arrays/stacks/queues etc to store entire array or part of array. I'm able to get answer in O(n*log n), but I'm looking for better solution.

• .NET: How to place my window near the notification area (systray)?

  - by Vilx-

  I'd like to display a little popup window next to the notification area. It's similar to what Outlook/Skype/Live! Messenger/etc does when it displays the notification about a new message. In my case it will have some input controls (textbox, datetimepicker, buttons...) so a simple bubble won't do. The trick is doing this correctly when the user has multiple monitors and/or the taskbar is not located at the bottom of the screen.
