  • PHP variable question

    - by Kyle Parisi
    This works: $customerBox = mysql_query("MY SQL STATEMENT HERE"); $boxRow = mysql_fetch_array($customerBox); $customerBox = mysql_query("MY SQL STATEMENT AGAIN"); while($item = mysql_fetch_assoc($customerBox)) { foreach ($item as $columnName = $value) { if (empty($value)) { print $columnName; } } } This does not: $customerBox = mysql_query("MY SQL STATEMENT HERE"); $boxRow = mysql_fetch_array($customerBox); while($item = mysql_fetch_assoc($customerBox)) { foreach ($item as $columnName = $value) { if (empty($value)) { print $columnName; } } } Why? I guess I don't understand how variables work yet.

  • What Design Pattern To Replace 'CurrentStep' Variable

    - by Rob P.
    Tried to search but didn't know how to phrase it. I've got some code that is essentially... Private CurMajorStep as Integer = 0 Private CurMinorStep as Integer = 0 Public Sub PerformNextStep() Select Case iMajorStep Case 0 ThingOne() Case 1 ThingTwo() Case 2 ThingThree() Case 3 ThingFour() Case 4 AnythingElse() Case 5 Finish() End Select End Sub And then, in some of those, the CurMinorStep keeps track of the current state of that particular 'step'. I hope that all makes sense. The code is messy and I know it's going to be problematic to maintain. Can someone point me to a clean OO pattern to handle 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?

  • Removing Unused (Unreferenced) Static Global Variable Constants in C++

    - by Synetech inc.
    Hi, I have a header file with a few common constants like names and stuff that are automatically included in each project (an example follows). The thing is that they are included in the compiled binary (EXE) whether they are used (referenced) or not. If I use DEFINEs instead, then naturally they are not included if they are not used, but of course consts are better than defines so… I tried Googling it, but the closest thing I could find was a question right here on SO that did not quite help. Matters of i18n aside, how can I keep the ones that are not used out of the binary, while still keeping it easy to use like this? Thanks. //COMMON.H: static const CString s_Company _T("Acme inc."); //etc. static const CString s_Digits _T("0123456789"); //TEST.CPP: #include common.h int main() { AfxMessageBox(s_Company); } //s_Company should be in the final EXE, but s_Digits should not be, but is

  • Difference between [object variable] and object.variable in Obj-C?

    - by John Smith
    I was working on a program today and hit this strange bug. I had a UIButton with an action assigned. The action was something like: -(void) someaction:(id) e { if ([e tag]==SOMETAG) { //dostuff } } What confuses me is that when I first wrote it, the if line was if (e.tag==SOMETAG) XCode refused to compile it, saying error: request for member 'tag' in 'e', which is of non-class type 'objc_object*' but I thought the two were equivalent. So under what circumstances are they not the same?

  • How do I make dynamic windows in Swing?

    - by Roman
    I have a general question. I would like to have a window containing some buttons, radio buttons, text fields and so on. So, user can do something (write text, select options and press buttons). As the result of the user activity window should change it structure/appearance some element should disappear and some appear. How do I program such "updates"? Should I close an old window and open a new one or I can modify content of window without closing it?

  • Dynamic decision on which class to use

    - by Sirupsen
    Hello, Let's say I have a class named Klass, and a class called Klass2. Depending on the user's input, I'd like to decide whether I'll call "hello_world" on Klass, or Klass2: class Klass def self.hello_world "Hello World from Klass1!" end end class Klass2 def self.hello_world "Hello World from Klass2!" end end input = gets.strip class_to_use = input puts class_to_use.send :hello_world The user inputs "Klass2" and the script should say: Hello World from Klass2! Obviously this code doesn't work, since I'm calling #hello_world on String, but I'd like to call #hello_world on Klass2. How do I "convert" the string into a referrence to Klass2 (or whatever the user might input), or how could I else would I achieve this behavior?

  • C Different answers for a variable when running 'Debug' and 'Start without debug'

    - by Craz
    I keep getting this weird output from my code everytime I use the 'start without degugging' (ctrl-F5) as opposed to normal 'debug' (F5). When I try to find the following value of norm_differnece in debug (pressing F5) mode, it gives me the correct answer for norm_difference normdifference = 1.000000 but in 'start without debugging' (pressing ctrl-f5) the wrong output normdifference = 1456816083547664100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000.000000 The following is a segment of code which is gives the output Note: X[] = is a array of stored DOUBLE values for(i=0;i<n;i++){ sum_difference += (pow((X[i*n]-X[i]),2)); } norm_difference = sqrt(norm_difference); for(i=0;i<n;i++){ sum_norm_1 += pow(X[i],2); } norm_1 = sqrt(norm_1); //Take square root of the sum of squares for the row printf("normdifference = %f \n norm_1 = %f \n",norm_difference,norm_1);

  • PHP function: find argument's variable name, and function calls line number

    - by Majid
    I want to do something like this for simplifying logging operations. Any idea what I should put in for ?[1]? and ?[2]?? function log_var($var) { $line = ?[1]?; $var_name = ?[2]?; $line--; $filepath = 'log-' . date('Y-m-d'). '.txt'; $message = "$line, $var_name = $var\n"; $fp = fopen($filepath, "a"); fwrite($fp, $message); fclose($fp); @chmod($filepath, 0666); return TRUE; } This how I'd use the function in code (numbers are assumed to be line numbers in actual code): 23 $a = 'hello'; 24 log_var($a); 25 $b = 'bye'; 26 log_var($b); And this is what I want to be written to the log file: 23, a = hello 25, b = bye

Please see the details below: Create table TableA ( ProjectID INT NOT NULL, ControlID INT NOT NULL, ControlCode Varchar(2) NOT NULL, ControlPoint Decimal NULL, ControlScore Decimal NULL, ControlValue Varchar(50) ) Sample Data ------------- ProjectID | ControlID | ControlCode | ControlPoint | ControlScore | ControlValue P001 1 A 30.44 65 Invalid P001 2 C 45.30 85 Valid Create table TableB ( ControlID INT NOT NULL, ControlChildID INT NOT NULL, ControlChildValue Varchar(200) NULL ) Sample Data ------------ ControlID | ControlChildID | ControlChildValue 1 100 Yes 1 101 No 1 102 NA 1 103 Others 2 104 Yes 2 105 SomeValue Output should be in a single row for a given ProjectID with all its Control values first & followed by child control values (based on the ControlCode (i.e.) ControlCode_Child (1, 2, 3...) and it should look like this

  • Parallel.For(): Update variable outside of loop

    - by TSS
    I'm just looking in to the new .NET 4.0 features. With that, I'm attempting a simple calculation using Parallel.For and a normal for(x;x;x) loop. However, I'm getting different results about 50% of the time. long sum = 0; Parallel.For(1, 10000, y => { sum += y; } ); Console.WriteLine(sum.ToString()); sum = 0; for (int y = 1; y < 10000; y++) { sum += y; } Console.WriteLine(sum.ToString()); My guess is that the threads are trying to update "sum" at the same time. Is there an obvious way around it?

  • Javascript: Inherit method from base class and return the subclass's private variable

    - by marisbest2
    I have the following BaseClass defined: function BaseClass (arg1,arg2,arg3) { //constructor code here then - var privateVar = 7500; this.getPrivateVar = function() { return privateVar; }; } I want to have the following subclass which allows changing privateVar like so: function SubClass (arg1,arg2,arg3,privateVar) { //constructor code here then - var privateVar = privateVar; } SubClass.prototype = new BaseClass(); Now I want SubClass to inherit the getPrivateVar method. However, when I try this, it always returns 7500 which is the value in the BaseClass and not the value of privateVar. In other words, is it possible to inherit a BaseClass's public methods but have any references in them refer to the SubClass's properties? And how would I do that?
