3 column html template - content overflows though there is clear both and height is 100%

- by MeltingDog

I have 3 divs within a wrapper: <div id="wrapper"> <div id="leftbar"> Lorem ipsum dolar sit amet </div> <div id="middle"> Lorem ipsum dolar sit amet </div> <div id="rightbar"> Lorem ipsum dolar sit amet </div> </div> Both 'leftbar' and 'middle' are floating left, whilst 'rightbar' is floating right. 'wrapper' has height:100%; clear:both; set. However, if there is a large amount of text or content in 'middle' it overflows the 'wrapper' div. I am struggling to figure out why this is occurring. My CSS is: #wrapper { width: 1000px; height: 100%; margin:auto; padding: 30px; margin-top: 40px; background-color:#FFF; color:#000; border: 2px solid #828fc4; clear:both; } #leftbar { float:left; width: 150px; min-height: 450px; padding: 5px; } #middle { float:left; height: 100%; width: 580px; padding-left: 20px; padding-right: 20px; border-right: 1px dotted #2B308C; border-left: 1px dotted #2B308C; } #rightbar { float:right; width: 200px; min-height: 450px; padding: 5px; } Any advice is appreciated!

Error reading values from dynamically created table rows in Android

- by jaymo

So I have a couple of dynamically created tablerows.Each TableRow has a couple of Textviews.I have a button that on clicked should get all the values of the second and third textviews in each Tablerow in the Table. I have tried to do this using the code below mSubmitOrders.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if(mTable.getChildCount()>1){ for(int i = 0; i < mTable.getChildCount(); i++){ TableRow tr = (TableRow)mTable.getChildAt(i); TextView code = (TextView) tr.getChildAt(1); TextView quantity = (TextView) tr.getChildAt(2); String Scode = code.getText().toString(); Log.i("TAG", Scode); String Squantity = quantity.getText().toString(); Log.i("TAG", Squantity); } } But I get the below errors (Logcat below).

css displaying divs inside a Tr fine in FireFox, but IE increases the width of the row...

- by Ronedog

I'm having some difficulty figuring out what is going on and how to fix it. I have some divs that contain some icons that are causing a width problem when displaying tabular data. If I remove the div's that contain the icons, the row width ends up the way I want it (See the firefox example below). Here's the view in Firefox which is what I want (notice the positioning of the icons circled in red, which is aligned on the same y coordinate, or thereabouts): Here's the view in IE7 (Notice what happens to the icons and the width of the grey line, which is the table row): Here's the HTML: <table> <tbody> <tr> <td> <span>stuff 1</span> <span>stuff 2</span> <div class="prop_edit"><img class="img_height14" src="edit.jpg"></div> <div class="prop_archive"><img class="img_height14" src="archive.jpg"></div> <div class="prop_delete"><img class="img_height14" src="delete.jpg"></div> <div style="display:none;"> <div>Links Here</div> </div> </td> </tr> </tbody> Heres the CSS: .prop_edit{ float:right; position: relative; top: 0px; right:50px; } .prop_archive{ float:right; position: relative; top: 0px; right:10px; } .prop_delete{ float:right; position: relative; top: 0px; right: -30px; } .img_height14{ height:14px; vertical-align:top; position:relative; } I've tried a bunch of different css things, but really am just hacking away hoping to figure something out. Anyone got some tips that could help me? Thanks in advance.

Comparator interface

- by 1ace1

ok I was going to edit my previous question but i wasnt sure if it was the right way to do it so i'll just give another question about Comparator, now i want to be able to sort with different ways. I have a bank checks and i want to sort with checkNumber then checkAmount i managed to do it with checkNumber but couldnt figure out how with checkAmount here is how i did it for checkNumber: import java.util.Comparator; public class Check implements Comparator { private int checkNumber; private String description; private double checkAmount; public Check() { } public Check(int newCheckNumber, double newAmountNumber) { setCheckNumber(newCheckNumber); setAmountNumber(newAmountNumber); } public String toString() { return checkNumber + "\t\t" + checkAmount; } public void setCheckNumber(int checkNumber) { this.checkNumber = checkNumber; } public int getCheckNumber() { return checkNumber; } public void setAmountNumber(double amountNumber) { this.checkAmount = amountNumber; } public double getAmountNumber() { return checkAmount; } @Override public int compare(Object obj1, Object obj2) { int value1 = ((Check) obj1).getCheckNumber(); int value2 = ((Check) obj2).getCheckNumber(); int result = 0; if (value1 > value2){ result = 1; } else if(value1 < value2){ result = -1; } return result; } } import java.util.ArrayList; import java.util.Collections; import test.CheckValue; public class TestCheck { public static void main(String[] args) { ArrayList List = new ArrayList(); List.add(new Check(445, 55.0)); List.add(new Check(101,43.12)); List.add(new Check(110,101.0)); List.add(new Check(553,300.21)); List.add(new Check(123,32.1)); Collections.sort(List, new Check()); System.out.println("Check Number - Check Amount"); for (int i = 0; i < List.size(); i++){ System.out.println(List.get(i)); } } } thank you very much in advance and please tell me if im submiting things in the wrong way.

recursion resulting in extra unwanted data

- by spacerace

I'm writing a module to handle dice rolling. Given x die of y sides, I'm trying to come up with a list of all potential roll combinations. This code assumes 3 die, each with 3 sides labeled 1, 2, and 3. (I realize I'm using "magic numbers" but this is just an attempt to simplify and get the base code working.) int[] set = { 1, 1, 1 }; list = diceroll.recurse(0,0, list, set); ... public ArrayList<Integer> recurse(int index, int i, ArrayList<Integer> list, int[] set){ if(index < 3){ // System.out.print("\n(looping on "+index+")\n"); for(int k=1;k<=3;k++){ // System.out.print("setting i"+index+" to "+k+" "); set[index] = k; dump(set); recurse(index+1, i, list, set); } } return list; } (dump() is a simple method to just display the contents of list[]. The variable i is not used at the moment.) What I'm attempting to do is increment a list[index] by one, stepping through the entire length of the list and incrementing as I go. This is my "best attempt" code. Here is the output: Bold output is what I'm looking for. I can't figure out how to get rid of the rest. (This is assuming three dice, each with 3 sides. Using recursion so I can scale it up to any x dice with y sides.) [1][1][1] [1][1][1] [1][1][1] [1][1][2] [1][1][3] [1][2][3] [1][2][1] [1][2][2] [1][2][3] [1][3][3] [1][3][1] [1][3][2] [1][3][3] [2][3][3] [2][1][3] [2][1][1] [2][1][2] [2][1][3] [2][2][3] [2][2][1] [2][2][2] [2][2][3] [2][3][3] [2][3][1] [2][3][2] [2][3][3] [3][3][3] [3][1][3] [3][1][1] [3][1][2] [3][1][3] [3][2][3] [3][2][1] [3][2][2] [3][2][3] [3][3][3] [3][3][1] [3][3][2] [3][3][3] I apologize for the formatting, best I could come up with. Any help would be greatly appreciated. (This method was actually stemmed to use the data for something quite trivial, but has turned into a personal challenge. :) edit: If there is another approach to solving this problem I'd be all ears, but I'd also like to solve my current problem and successfully use recursion for something useful.

backbonejs remove anomaly concept

- by user1537158

I was building a small app for adding and deleting li from ul using Backbonejs.One of the SO members cymen helped me code it, using that i tailored the code a little.currently if i add one element and delete , it works , but the second time i add an element (to ul) and go to delete it , i get Uncaught TypeError: Cannot call method 'remove' of undefined Pasting my code here , HTML : <input type="text" id="name"> <button id="add">Add</button> <ul id="mylist"></ul> JS: $(function(){ var myCollection = Backbone.Collection.extend(); var myView = Backbone.View.extend({ el:$('body'), tagName:'li', initialize : function(e){ this.collection.bind("add",this.render,this); this.collection.bind("remove",this.render,this); }, events:{ 'click #add' : 'addfoo' }, addfoo : function(){ var myname= $('#name').val(); $('#name').val(''); this.collection.add({name:myname}); }, render : function(){ $('#mylist').empty(); this.collection.each(function(model){ console.log("myView"); var remove = new myRemoveView({model:model}); remove.render(); }); } }); var myRemoveView = Backbone.View.extend({ el:$('body'), events:{ 'click .button':'removeFoo' }, removeFoo : function(){ console.log("here"); this.model.collection.remove(this.model); }, render : function(){ console.log("second view"); $('#mylist').append('<li>'+this.model.get('name') + "<button class='button'>"+"delete"+"</button></li>"); return; } }); var view = new myView({collection: new myCollection()}); }); Two things i did not understand : i) in the removeFoo function , we write this.model.collection.remove(this.model) shouldnt this have been this.collection.model.remove , something of that sort ? ii) i add a li to ul , then i delete it , when i add another li (appending to ul works perfect) but this time when i go to delete it throws me the above error : Uncaught TypeError :cannot call method 'remove' of undefined can you please help me figure out these 2 doubts in my code , btw SO member cymen's code works like a charm only my tailored code (above) is giving me errors. SO member cymen's code : JS Fiddle for his code Thank you

Creating array from two arrays

- by binoculars

I'm having troubles trying to create a certain array. Basicly, I have an array like this: [0] => Array ( [id] => 12341241 [type] => "Blue" ) [1] => Array ( [id] => 52454235 [type] => "Blue" ) [2] => Array ( [id] => 848437437 [type] => "Blue" ) [3] => Array ( [id] => 387372723 [type] => "Blue" ) [4] => Array ( [id] => 73732623 [type] => "Blue" ) ... Next, I have an array like this: [0] => Array ( [id] => 34141 [type] => "Red" ) [1] => Array ( [id] => 253532 [type] => "Red" ) [2] => Array ( [id] => 94274 [type] => "Red" ) I want to construct an array, which is a combination of the two above, using this rule: after 3 Blues, there must be a Red: Blue1 Blue2 Blue3 Red1 Blue4 Blue5 Blue6 Red2 Blue7 Blue8 Blue9 Red3 Note that the their can be more Red's than Blue's, but also more Blue's than Red's. If the Red's run out, it should begin with the first one again. Example: let's say there are only two Red's: Blue1 Blue2 Blue3 Red1 Blue4 Blue5 Blue6 Red2 Blue7 Blue8 Blue9 Red1 ... ... If the Blue's run out, the Red's should append until they run out too. Example: let's say there are 5 Blue's, and 5 Red's: Blue1 Blue2 Blue3 Red1 Blue4 Blue5 Red2 Red3 Red4 Red5 Note: the arrays come from mysql-fetches. Maybe it's better to fetch them while building the new array? Anyway, the while-loops got to me, I can't figure it out... Any help is much appreciated!

How does the CLR (.NET) internally allocate and pass around custom value types (structs)?

- by stakx

Question: Do all CLR value types, including user-defined structs, live on the evaluation stack exclusively, meaning that they will never need to be reclaimed by the garbage-collector, or are there cases where they are garbage-collected? Background: I have previously asked a question on SO about the impact that a fluent interface has on the runtime performance of a .NET application. I was particuarly worried that creating a large number of very short-lived temporary objects would negatively affect runtime performance through more frequent garbage-collection. Now it has occured to me that if I declared those temporary objects' types as struct (ie. as user-defined value types) instead of class, the garbage collector might not be involved at all if it turns out that all value types live exclusively on the evaluation stack. What I've found out so far: I did a brief experiment to see what the differences are in the CIL generated for user-defined value types and reference types. This is my C# code: struct SomeValueType { public int X; } class SomeReferenceType { public int X; } . . static void TryValueType(SomeValueType vt) { ... } static void TryReferenceType(SomeReferenceType rt) { ... } . . var vt = new SomeValueType { X = 1 }; var rt = new SomeReferenceType { X = 2 }; TryValueType(vt); TryReferenceType(rt); And this is the CIL generated for the last four lines of code: .locals init ( [0] valuetype SomeValueType vt, [1] class SomeReferenceType rt, [2] valuetype SomeValueType <>g__initLocal0, // [3] class SomeReferenceType <>g__initLocal1, // why are these generated? [4] valuetype SomeValueType CS$0$0000 // ) L_0000: ldloca.s CS$0$0000 L_0002: initobj SomeValueType // no newobj required, instance already allocated L_0008: ldloc.s CS$0$0000 L_000a: stloc.2 L_000b: ldloca.s <>g__initLocal0 L_000d: ldc.i4.1 L_000e: stfld int32 SomeValueType::X L_0013: ldloc.2 L_0014: stloc.0 L_0015: newobj instance void SomeReferenceType::.ctor() L_001a: stloc.3 L_001b: ldloc.3 L_001c: ldc.i4.2 L_001d: stfld int32 SomeReferenceType::X L_0022: ldloc.3 L_0023: stloc.1 L_0024: ldloc.0 L_0025: call void Program::TryValueType(valuetype SomeValueType) L_002a: ldloc.1 L_002b: call void Program::TryReferenceType(class SomeReferenceType) What I cannot figure out from this code is this: Where are all those local variables mentioned in the .locals block allocated? How are they allocated? How are they freed? Why are so many anonymous local variables needed and copied to-and-fro only to initialize my two local variables rt and vt?

Need help with tweaking a Dropdown with three options, user selects one - a hidden div appears with correct fields

- by Jack

Hello Again, I posted a question on here and got an answer within minutes I'm hoping the wizards on here can help me again. Okay so I'm using a script I found online to try and add this function to a shopping cart form. Here's the setup. I have a payment method dropdown with Visa, Mastercard and Bank Withdrawal as the options. For the credit cards I have one hidden div with a certain set of fields, and for the bank I have another hidden div. Each of the divs have named ID's - #payCredit and #payBank The css for both have margin: 0px and display: none; Here's a peice of javascript I used successfuly on a shipping address checkbox `function toggleLayer( whichLayer ) { var elem, vis; if( document.getElementById ) // this is the way the standards work elem = document.getElementById( whichLayer ); else if( document.all ) // this is the way old msie versions work elem = document.all[whichLayer]; else if( document.layers ) // this is the way nn4 works elem = document.layers[whichLayer]; vis = elem.style; // if the style.display value is blank we try to figure it out here if(vis.display==''&&elem.offsetWidth!=undefined&&elem.offsetHeight!=undefined) vis.display = (elem.offsetWidth!=0&&elem.offsetHeight!=0)?'block':'none'; vis.display = (vis.display==''||vis.display=='block')?'none':'block'; }` I was hoping I could change it slightly to meet my needs. Here's the dropdown <label>Payment Method:</label> <select name="payment" id="payment" class="dropdown3" style="width:8em"> <option selected="selected">Select</option> <option value="Visa" onclick="javascript:toggleLayer('payCredit');">Visa</option> <option value="MasterCard" onclick="javascript:toggleLayer('payCredit');">Mastercard</option> <option value="Direct" onclick="javascript:toggleLayer('payBank');">Direct Withdraw</option> </select></li> The current result is that it kinda works. I can open the dropdown and select Visa and it appears, if I select Visa again it disappears, if I select Visa and then select bank, both appear. You can see what i'm working on here - http://test.sharevetcare.com/bestfriends/cart3.html

How to get ImageButton size within Android GridView?

- by wufoo

I'm subclassing ImageButton in order to draw lines on it and trying to figure out where the actual button coordinates are within my gridview. I am using onGlobalLayout to setup Top, Bottom, Right and Left, but these seem to be for the actual "square" within the grid, and not the actual button (see image). The purple lines are drawn in myImageButton.onDraw() using coords gathered from myImageButton.onGlobalLayout(). I thought these would be for the button, but they seem to be from something else. Not sure what. I'd like the purple lines to match the outline of the button so the lines I draw appear on the button and not just floating out in the LinearLayout somewhere. The light blue is the background color of the vertical LinearLayout holding the Textview (for the number) and myImageButton. Any way to get the actual button size? XML Layout: <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/lay_cellframe" android:layout_width="fill_parent" android:layout_height="fill_parent" > <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="fill_vertical|fill_horizontal" android:orientation="vertical" > <TextView android:id="@+id/tv_cell" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_margin="2dp" android:gravity="center" android:text="TextView" android:textSize="10sp" /> <com.example.icaltest2.myImageButton android:id="@+id/imageButton1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:layout_margin="0dp" android:adjustViewBounds="false" android:background="@android:drawable/btn_default" android:scaleType="fitXY" android:src="@android:color/transparent" /> </LinearLayout> </FrameLayout> myImageButton.java public myImageButton (Context context, AttributeSet attrs) { super (context, attrs); mBounds = new Rect(); ViewTreeObserver vto = this.getViewTreeObserver (); vto.addOnGlobalLayoutListener (ogl); Log.d (TAG, "myImageButton"); } ... OnGlobalLayoutListener ogl = new OnGlobalLayoutListener() { @Override public void onGlobalLayout () { Rect b = getDrawable ().getBounds (); mBtnTop = b.centerY () - (b.height () / 2); mBtnBot = b.centerY () + (b.height () / 2); mBtnLeft = b.centerX () - (b.width () / 2); mBtnRight = b.centerX () + (b.width () / 2); } }; ... @Override protected void onDraw (Canvas canvas) { super.onDraw (canvas); Paint p = new Paint (); p.setStyle (Paint.Style.STROKE); p.setStrokeWidth (1); p.setColor (Color.MAGENTA); canvas.drawCircle (mBtnLeft, mBtnTop, 2, p); canvas.drawCircle (mBtnLeft, mBtnBot, 2, p); canvas.drawCircle (mBtnRight, mBtnTop, 2, p); canvas.drawCircle (mBtnRight, mBtnBot, 2, p); canvas.drawRect (mBtnLeft, mBtnTop, mBtnRight, mBtnBot, p); }

Pass PHP variables without being seen when working with a database generated list

- by Wilcoholic

Looking for any help regarding the problem. Here's the deal: I have a database that has a teams table and it contains team_id. On one of my pages, I generate a list of links that contain the team_id of the creator in their get URL. I need the team_id on the next page but can't figure out how to pass it through any other way. Using a form and POST isn't an option because this method would only pass through the last links data on the list. Storing in a session isn't an option either because there is no way to discretely pass the the variables I need to a function to set the session variables. I have tried and it can pretty easily be viewed from viewing the source code. So here's some sample code to see exactly what I'm dealing with. <? if(mysql_num_rows($result2)>0){ ?> <a class="fltrt btn btn-danger btn-small" onclick="test()" href="acceptmatch-exec.php?match_id=<?php echo $match_id; ?>&team_id=<?php echo $team_id;?>&action=cancel">Cancel Match</a> <?}else{?> <a class="fltrt btn btn-success btn-small" href="acceptmatch-exec.php?match_id=<?php echo $match_id; ?>&team_id=<?php echo $team_id;?>&action=accept">Accept Match</a> <?} ?> The code above is generated multiple times on a page via a while loop that was excluded. I want to pass the match_id and team_id variables without being seen anywhere. If I made this a form, it wouldn't pass the correct variables unless there is only one result at the time (not likely). I'm sure there has to be an easy method that is eluding me, so please share thoughts on how to solve this. I feel as though I am not explaining it well enough, but it's not really easy to explain. I basically want something that works like GET but acts like POST and can be hidden from people viewing source code or link locations. Thanks

How to check total cache size using a program

- by user1888541

so I'm having some trouble creating a program to measure cache size in C. I understand the basic concept of going about this but I'm still having trouble figuring out exactly what I am doing wrong. Basically, I create an array of varying length (going by power of 2s) and access each element in the array and put it in a dummy variable. I go through the array and do this around 1000 times to negate the "noise" that would otherwise occur if I only did it once to get an accurate measurement for time. Then, I look for the size that causes a big jump in access time. Unfortunately, this is where I am having my problem, I don't see this jump using my code and clearly I am doing something wrong. Another thing is that I used /proc/cpuinfo to check the cache and it said the size was 6114 but that was not a power of 2. I was told to go by powers of 2 to figure out the cache can anyone explain why this is? Here is the just of my code...I will post the rest if need be { struct timeval start; struct timeval end; // int n = 1; // change this to test different sizes int array_size = 1048576*n; // I'm trying to check the time "manually" first before creating a loop for the program to do it by itself this is why I have a separate "n" variable to increase the size char x = 0; int i =0, j=0; char *a; a =malloc(sizeof(char) * (array_size)); gettimeofday(&start,NULL); for(i=0; i<1000; i++) { for(j=0; j < array_size; j += 1) { x = a[j]; } } gettimeofday(&end,NULL); int timeTaken = (end.tv_sec * 1000000 + end.tv_usec) - (start.tv_sec *1000000 + start.tv_usec); printf("Time Taken: %d \n", timeTaken); printf("Average: %f \n", (double)timeTaken/((double)array_size); }

Specializing function template for both std::string and char*

- by sad_man

As the title says I want to specialize a function template for both string and char pointer, so far I did this but I can not figure out passing the string parameters by reference. #include <iostream> #include <string> template<typename T> void xxx(T param) { std::cout << "General : "<< sizeof(T) << std::endl; } template<> void xxx<char*>(char* param) { std::cout << "Char ptr: "<< strlen(param) << std::endl; } template<> void xxx<const char* >(const char* param) { std::cout << "Const Char ptr : "<< strlen(param)<< std::endl; } template<> void xxx<const std::string & >(const std::string & param) { std::cout << "Const String : "<< param.size()<< std::endl; } template<> void xxx<std::string >(std::string param) { std::cout << "String : "<< param.size()<< std::endl; } int main() { xxx("word"); std::string aword("word"); xxx(aword); std::string const cword("const word"); xxx(cword); } Also template<> void xxx<const std::string & >(const std::string & param) thing just does not working. If I rearranged the opriginal template to accept parameters as T& then the char * is required to be char * & which is not good for static text in code. Please help !

Weird seg fault problem

- by bluedaemon

Greetings, I'm having a weird seg fault problem. My application dumps a core file at runtime. After digging into it I found it died in this block: #include <lib1/c.h> ... x::c obj; obj.func1(); I defined class c in a library lib1: namespace x { struct c { c(); ~c(); void fun1(); vector<char *> _data; }; } x::c::c() { } x::c::~c() { for ( int i = 0; i < _data.size(); ++i ) delete _data[i]; } I could not figure it out for some time till I ran nm on the lib1.so file: there are more function definitions than I defined: x::c::c() x::c::c() x::c::~c() x::c::~c() x::c::func1() x::c::func2() After searching in code base I found someone else defined a class with same name in same namespace, but in another library lib2 as follows: namespace x { struct c { c(); ~c(); void func2(); vector<string> strs_; }; } x::c::c() { } x::c::~c() { } My application links to lib2, which has dependency on lib1. This interesting behavior brings several questions: Why would it even work? I would expect a "multiple definitions" error while linking against lib2 (which depends upon lib1) but never had such. The application seems to be doing what's defined in func1 except it dumps a core at runtime. After attaching debugger, I found my application calls the ctor of class c in lib2, then calls func1 (defined in lib1). When going out of scope it calls dtor of class c in lib2, where the seg fault occurs. Can anybody teach me how this could even occur? How can I prevent such problems from happening again? Is there any C++ syntax I can use? Forgot to mention I'm using g++ 4.1 on RHEL4, thank you very much!

Adding Related Entities without using navigation properties

- by Barisa Puter

I have the following classes, set for testing: public class Company { [DatabaseGenerated(DatabaseGeneratedOption.Identity)] public int Id { get; set; } public string Name { get; set; } } public class Employee { [DatabaseGenerated(DatabaseGeneratedOption.Identity)] public int Id { get; set; } public string Name { get; set; } public int CompanyId { get; set; } public virtual Company Company { get; set; } } public class EFTestDbContext : DbContext { public DbSet<Employee> Employees { get; set; } public DbSet<Company> Companies { get; set; } } For the sake of testing, I wanted to insert one company and one employee for that company with single SaveChanges call, like this: Company company = new Company { Name = "Sample company" }; context.Companies.Add(company); // ** UNCOMMENTED FOR TEST 2 //Company company2 = new Company //{ // Name = "Some other company" //}; //context.Companies.Add(company2); Employee employee = new Employee { Name = "Hans", CompanyId = company.Id }; context.Employees.Add(employee); context.SaveChanges(); Even though I am not using navigational properties, but instead I've made relation over Id, this somehow mysteriously worked - employee was saved with proper foreign key to company which got updated from 0 to real value, which made me go ?!?! Some hidden C# feature? Then I've decided to add more code, which is commented in the snippet above, making it to be inserting of 2 x Company entity and 1 x Employee entity, and then I got exception: Unable to determine the principal end of the 'CodeLab.EFTest.Employee_Company' relationship. Multiple added entities may have the same primary key. Does this mean that in cases where foreign key is 0, and there is a single matching entity being inserted in same SaveChanges transaction, Entity Framework will assume that foreign key should be for that matching entity? In second test, when there are two entities matching the relation type, Entity Framework throws an exception as it is not able to figure out to which of the Companies Employee should be related to.

Line Graph CGPoints from NSMutableArray

- by Mattog1456

I have been trying to adapt the code from the accelerometer example such that when the user depresses a uibutton a point is added to a line graph. Working on the converting two floats, which are the result of calculate as below into a CGPoint and converting the CGPoint into an NSValue and then adding this to a NSMutableArray with the following -(IBAction)calculate:(id)sender { self.points = [NSMutableArray array]; CGPoint pt = CGPointMake(d, c); [self.points addObject:[NSValue valueWithCGPoint:pt]]; NSLog(@"%@", NSStringFromCGPoint(pt)); NSLog(@"%@", [NSString stringWithFormat:@"%d points", self.points.count ]); } But for some reason I am only getting one object stored in the array, it seems everytime push the calculate button the object pt gets overwritten, on the plus side it has the correct x,y coords. Any ideas on this one? UPDATE Removed self.points = [NSMutableArray array]; and placed it in view did load, also set the first points to 0,0. so that is working ok. Now the next problem is that I have a Graph subclass where the CG Drawing is taking place. I am trying to figure out a simple way to be able to access the above NSMutableArray which is in a ViewController class from the graph class. Am so close to the end but am really stuck, any help would be great. Still trying to draw a line graph on a UIView which is on a UIScrollview. The draw rect method is in the UIView Subclass and everything is working there, I have gridlines and labels on the axis and I can draw manually onto it. But the problem I have is that I cannot read the NSMutableArray of the CGPoints, which are the x and y coords. The ViewController performs a calculation and the results are written to the NSMutable array and this is all working fine as well, I can see the CGpoints and their values being written with NSLogs in the ViewController. I have tried various ways to set the NSMutableArray up as a global but to no avail, everything runs but while I can see the points being written in the ViewController they are just not visible to the UIView Subclass. I have also tried to use the addObserver and observeValueForKeyPath methods and once again while everything runs the subclass cannot see the array. Any ideas, suggestions, tips or thoughts would be great

Have main thread wait for a boost thread complete a task (but not finish).

- by JAKE6459

I have found plenty on making one thread wait for another to finish executing before continuing, but that is not what I wanted to do. I am not very familiar with using any multi-threading apis but right now I'm trying to learn boost. My situation is that I am using my main thread (the starting one from int main()) to create an instance of a class that is in charge of interacting with the main GUI. A class function is then called that creates a boost thread which in turn creates the GUI and runs the message pump. The thing I want to do is when my main thread calls the classes member function to create the GUI, I don't want that function to return until I tell it to from the newly created thread. This way my main thread can't continue and call more functions from the GUI class that interact with the GUI thread until that thread has completed GUI creation and entered the message loop. I think I may be able to figure it out if it was multiple boost thread objects interacting with each other, but when it is the main thread (non-boost object) interacting with a boost thread object, I get lost. Eventually I want a loop in my main thread to call a class function (among other tasks) to check if the user as entered any new input into the GUI (buy any changes detected by the message loop being updated into a struct and changing a bool to tell the main thread in the class function a change has occurred). Any suggestions for any of this would be greatly appreciated. This is the member function called by the main thread. int ANNGUI::CreateGUI() { GUIMain = new Main(); GUIThread = new boost::thread(boost::bind(&Main::MainThreadFunc, GUIMain)); return 0; }; This is the boost thread starting function. void Main::MainThreadFunc() { ANNVariables = new GUIVariables; WndProc = new WindowProcedure; ANNWindowsClass = new WindowsClass(ANNVariables, WndProc); ANNWindow = new MainWindow(ANNVariables); GUIMessagePump = new MessagePump; ANNWindow-ShowWindows(); while(true) { GUIMessagePump-ProcessMessage(); } }; BTW, everything compiles fine and when I run it, it works I just put a sleep() in the main thread so I can play with the GUI a little.

Type casting int into double C++

- by user1705380

I am new to programming and this might be an obvious question, though i cannot for life of me figure out why my program is not returning as a double. I am suppose to write a stocks program that takes in shares of stock, whole dollar portion of price and the fraction portion. And the fraction portion is to be inputted as two int values, and include a function definition with 3 int values.The function returns the price as a double. #include <iostream> using namespace std; int price(int, int, int); int main() { int dollars, numerator, denominator, price1, shares; char ans; do { cout<<"Enter the stock price and the number of shares.\n"; cout<<"Enter the price and integers: Dollars, numerator, denominator\n"; cin>>dollars>>numerator>>denominator; cout<<"Enter the number of shares held\n"; cin>>shares; cout<<shares; price1 = price(dollars,numerator,denominator); cout<<" shares of stock with market price of "; cout<< dollars << " " << numerator<<'/'<<denominator<<endl; cout<<"have a value of " << shares * price1<<endl; cout<<"Enter either Y/y to continue"; cin>>ans; }while (ans == 'Y' || ans == 'y'); system("pause"); return 0; } int price(int dollars, int numerator, int denominator) { return dollars + numerator/static_cast<double>(denominator); }

How to pass an object from a Frame to another Frame in a Windows 8 Style App

- by Mythul

I have problem that i just cant figure out right now. I am trying to develop a Windows-8 style app and im stuck implementing this functionality. I have a MainWindow which contains a ListBox and a Button (lets say addButton). When i click the button i navigate to a new page, lets say AddCustomerPage with this.Frame.Navigate(typeof (AddCustomerPage)); AddCustomerPage has 1 textBox and 1 button (lets say doneButton. When i click the button i want the string in the textBox to be added to the ListBox on the previous page. This is my current functionality: 1. MainWindow is created. Click addButton AddCustomer page is created. MainWindow is destroyed(problem). Click doneButton A MainWindow object is created with a ListBox with 1 item. Repeat the add process, i always get a MainWindow with a ListBox with 1 item. Thanks for the help. Here is the code: public sealed partial class MainPage : Page { public MainPage() { this.InitializeComponent(); this.brainPageController = new PageController(); // add items from the List<String> to the listBox listGoals.ItemsSource = brainPageController.GetListGoals(); } protected override void OnNavigatedTo(NavigationEventArgs e) { var parameter = e.Parameter as String; // a simple controller that adds a string to a List<string> brainPageController.AddGoal(parameter); } private void addButton_Click(object sender, RoutedEventArgs e) { this.Frame.Navigate(typeof (GoalsInfo)); } // VARIABLES DECLARATION private PageController brainPageController; } public sealed partial class GoalsInfo : WinGoalsWIP.Common.LayoutAwarePage { public GoalsInfo() { this.InitializeComponent(); this.brainPageController = new PageController(); } protected override void LoadState(Object navigationParameter, Dictionary<String, Object> pageState) { } protected override void SaveState(Dictionary<String, Object> pageState) { } private void Button_Click_1(object sender, RoutedEventArgs e) { brainPageController.AddGoal(nameTextBox.Text); this.Frame.Navigate(typeof(MainPage), nameTextBox.Text); } // VARIABLES DECLARATION PageController brainPageController; }

How to pass multiple PHP variables to a jQuery function?

- by jcpeden

I'm working on a Wordpress plugin. I need to pass plugin directories (that can change depending on an individual's installation) to a jquery function. What is the best way of doing this? The version of the plugin that I can to work on had included all the javascript in the PHP file so the functions were parsed along with the rest of the content before being rendered in a browser. I'm looking at AJAX but I think it might be more complicated than I need. I can get away with just two variables in this case (directories, nothing set by the user). As I've read its good practice, I'm trying to keep the js and php separate. When the plugin initializes, it call the js file: //Wordpress calls the .js when the plugin loads wp_enqueue_script( 'wp-backitup-funtions', plugin_dir_url( __FILE__ ) . 'js/wp-backitup.js', array( 'jquery' ) ); Then I'm in the .js file and need to figure out how to generate the following variables: dir = '<?php echo content_url() ."/plugins"; ?>'; dir = '<?php echo content_url() ."/themes"; ?>'; dir = '<?php echo content_url() ."/uploads"; ?>'; And run the parse the following requests: xmlhttp.open("POST","<?php echo plugins_url() .'/wp-backitup/includes/wp-backitup-restore.php'); ?>",true); xmlhttp.open("POST","<?php echo plugins_url() .'/wp-backitup/includes/wp-backitup-start.php'); ?>",true); xmlhttp.open("POST","<?php echo plugins_url() .'/wp-backitup/wp-backitup-directory.php'); ?>",true); xmlhttp.open("POST","<?php echo plugins_url() .'/wp-backitup/wp-backitup-db.php'); ?>",true); window.location = "<?php echo plugins_url() .'/wp-backitup/backitup-project.zip'); ?>"; xmlhttp.open("POST","<?php echo plugins_url() .'/wp-backitup/wp-backitup-delete.php'); ?>",true); Content URL and Plugins URL differ only by /plugins/ so if I was hard pressed, I would only really need to make a single PHP request and then bring this into the JS.

Second query to SQLite (on iPhone) errors.

- by Luke

Hi all, On the iPhone, I am developing a class for a cart that connects directly to a database. To view the cart, all items can be pulled from the database, however, it seems that removing them doesn't work. It is surprising to me because the error occurs during connection to the database, except not the second time I connect even after the DB has been closed. #import "CartDB.h" #import "CartItem.h" @implementation CartDB @synthesize database, databasePath; - (NSMutableArray *) getAllItems { NSMutableArray *items = [[NSMutableArray alloc] init]; if([self openDatabase]) { const char *sqlStatement = "SELECT * FROM items;"; sqlite3_stmt *compiledStatement; if(sqlite3_prepare_v2(cartDatabase, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) { while(sqlite3_step(compiledStatement) == SQLITE_ROW) { int rowId = sqlite3_column_int(compiledStatement, 0); int productId = sqlite3_column_int(compiledStatement, 1); NSString *features = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 2)]; int quantity = sqlite3_column_int(compiledStatement, 3); CartItem *cartItem = [[CartItem alloc] initWithRowId:rowId productId:productId features:features quantity:quantity]; [items addObject:cartItem]; [cartItem release]; } } sqlite3_finalize(compiledStatement); } [self closeDatabase]; return items; } - (BOOL) removeCartItem:(CartItem *)item { sqlite3_stmt *deleteStatement; [self openDatabase]; const char *sql = "DELETE FROM items WHERE id = ?"; if(sqlite3_prepare_v2(cartDatabase, sql, -1, &deleteStatement, NULL) != SQLITE_OK) { return NO; } sqlite3_bind_int(deleteStatement, 1, item.rowId); if(SQLITE_DONE != sqlite3_step(deleteStatement)) { sqlite3_reset(deleteStatement); [self closeDatabase]; return NO; } else { sqlite3_reset(deleteStatement); [self closeDatabase]; return YES; } } - (BOOL) openDatabase { if(sqlite3_open([databasePath UTF8String], &cartDatabase) == SQLITE_OK) { return YES; } else { return NO; } } - (void) closeDatabase { sqlite3_close(cartDatabase); } The error occurs on the line where the connection is opened in openDatabase. Any ideas? Need to flush something? Something gets autoreleased? I really can't figure it out. --Edit-- The error that I receive is GDB: Program received signal "EXC_BAD_ACCESS". --Edit-- I ended up just connecting in the init and closing in the free methods, which might not be the proper way, but that's another question altogether so it's effectively persistent instead of connecting multiple times. Still would be nice to know what was up with this for future reference.

Display Commas in Large Numbers: JavaScript

- by user3723918

I'm working on a customized calculator, which is working pretty well except that I can't figure out how to get the generated numbers to display commas within the number. For example, it might spit out "450000" when I need it to say "450,000". This thread gives a number of suggestions on how to create a new function to deal with the problem, but I'm rather new to JavaScript and I don't really know how to make such a function interact with what I have now. I'd really appreciate any help as to how to get generated numbers with commas! :) HTML: <table id="inputValues"> <tr> <td>Percentage:</td> <td><input id="sempPer" type="text"></td> </tr> <tr> <td>Price:</td> <td><input id="unitPrice" type="text"></td> </tr> <tr> <td colspan="2"><input id="button" type="submit" value="Calculate"></td> </tr> </table> <table id="revenue" class="TFtable"> <tr> <td class="bold">Market Share</td> <td class="bold">Partner A</td> <td class="bold">Partner B</td> </tr> <tr> <td class="bold">1%</td> <td><span id="moss1"></span></td> <td><span id="semp1"></span></td> </tr> </table> </form> JavaScript: <script> function calc() { var z = Number(document.getElementById('sempPer').value); var x = Number(document.getElementById('unitPrice').value); var y = z / 100; var dm1 = .01 * 50000 * x * (1-y); var se1 = .01 * 50000 * x * y; document.getElementById("moss1").innerHTML= "$"+Number(dm1).toFixed(2); document.getElementById("semp1").innerHTML= "$"+Number(se1).toFixed(2); } </script>

Changing a select input to a checkbox acting as an on/off toggle switch in Rails

- by Ribena

I have a set of 7 dropdown inputs allowing admins to say whether they are open or closed for business on a given day. I'd like that changed to 7 open/closed switches (presumably styled checkboxes?) but can't figure out how to do this! Here are the relevant bits of code I currently have (prior to any change): app/view/backend/inventory_pool/edit.html.haml - content_for :title, @inventory_pool = form_for [:backend, @inventory_pool], html: {name: "form"} do |f| .content - if is_admin? %a.button{:href => root_path}= _("Cancel") %button.button{:type => :submit}= _("Save %s") % _("Inventory Pool") %section %h2= _("Basic Information") .inner .field.text .key %h3= "#{_("Print Contracts")}" %p.description .value .input %input{type: "checkbox", name: "inventory_pool[print_contracts]", checked: @inventory_pool.print_contracts} %section#workdays %h2= _("Workdays") .inner - [1,2,3,4,5,6,0].each do |i| .field.text .key %h3= "#{I18n.t('date.day_names')[i]}" .value .input %select{:name => "store[workday_attributes][workdays][]"} %option{:label => _("Open"), :value => Workday::WORKDAYS[i]}= _("Open") %option{:label => _("Closed"), :value => "", :selected => @store.workday.closed_days.include?(i) ? true : nil}= _("Closed") app/models/workday.rb class Workday < ActiveRecord::Base belongs_to :inventory_pool WORKDAYS = ["sunday", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday"] def is_open_on?(date) return false if date.nil? case date.wday when 1 return monday when 2 return tuesday when 3 return wednesday when 4 return thursday when 5 return friday when 6 return saturday when 0 return sunday else return false #Should not be reached end end def closed_days days = [] days << 0 unless sunday days << 1 unless monday days << 2 unless tuesday days << 3 unless wednesday days << 4 unless thursday days << 5 unless friday days << 6 unless saturday days end def workdays=(wdays) WORKDAYS.each {|workday| write_attribute(workday, wdays.include?(workday) ? true : false)} end end And in app/controllers/backend/inventory_pools_controller I have this (abridged): def update @inventory_pool ||= InventoryPool.find(params[:id]) process_params params[:inventory_pool] end def process_params ip ip[:print_contracts] ||= "false" # unchecked checkboxes are *not* being sent ip[:workday_attributes][:workdays].delete "" if ip[:workday_attributes] end
