  • Understanding PHP's way of reading if statements

    - by Masi
    How does PHP read if statements? I have the following if statements in this order if ( $number_of_figures_in_email < 6) { -- cut: gives false } if($number_of_emails > 0) { -- cut: gives false } if ( $number_of_emails == 0) { -- cut: gives true } The code behaves randomly. It sometimes goes to the third if clause and gives me a success, while sometimes to the one of the first two if clauses when the input variables are constant. This suggests me that I cannot code only with if statements.

  • Java execution details in System.out

    - by John
    As I remember there is a magic command line option in Java that turn on writing of operations that are currently executed to console. The output was looked like byte code. I do not mean -verbose, because it prints only class loading, while this option outputs information like memory allocation etc.

  • How do I call a Asp.Net textbox in CSS?

    - by mw
    I hope this isn't too difficult, obviously you can call HTML tags such as fieldset, label and legends and also textboxes. However how does one call an asp:textbox, i have tried just textbox, asp:textbox, input.textbox but nothing seems to work. This is something that should be really straight forward to do and I can't waste any more time figuring it out. Thanks.

  • 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?

  • Retrieving the value of a concatenated variable within a Java FOR loop

    - by Rajat
    I have been using this "logic" in C++ and VB with success, but am tied up in Java... Simply put, public void DataProviderExample(String user, String pwd, String no_of_links, String link1, String link2, String link3) { for (int i=1;i<=no_of_links;i++) { String link = "link"+i; System.out.println(link); } Now, if the variables link1, link2 and link3 have a value of "X", "Y" and "Z" respectively, upon running this program, I get the following output - link1 link2 link3 What I want is - X Y Z Any ideas?

  • DisplayFor ignores metadata

    - by Juvaly
    For my Contact class, the property EmailAddress is marked with the [DataType(DataType.EmailAddress)] attribute. In my view, using Html.Display("EmailAddress") and Html.DisplayFor(c => c.EmailAddress) yields different results. The former outputs a mailto: link, which is the expected behavior, while the latter simply outputs the email address as plain text. My question is why the different behavior, I expected these two methods to have the same output.

  • 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; }
