  • Modifying DOM of a webpage

    - by Prashant Singh
    The structure of a webpage is like this :- <div id='abc'> <div class='a'>Some contents here </div> <div class='b'>Some other contents< </div> </div> My aim is to add this after the class a in above structure. <div class='a'>Some other contents here </div> So that final structure looks like this :- <div id='abc'> <div class='a'>Some contents here </div> <div class='a'>Some other contents here </div> <div class='b'>Some other contents< </div> </div> Can there be a better way to do this using DOM properties. I was thinking of naive way of parsing the content and updating. Please comment if I am unclear in asking my doubt !

  • Randomly Position A Div

    - by Connie
    I'm looking for a way to randomly position a div anywhere on a page (ONCE per load). I'm currently programming a PHP-based fantasy pet simulation game. One of the uncommon items on the game is a "Four Leaf Clover." Currently, users gain "Four Leaf Clovers" through random distribution - but I would like to change that (it's not interactive enough!). What I Am Trying To Do: The idea is to make users search for these "Four Leaf Clovers" by randomly placing this image anywhere on the page: (my rendition of a four leaf clover) I'd like to do this using a Java/Ajax script that generates a div, and then places it anywhere on the page. And does not move it once it's been placed, until the page is reloaded. I've tried so many Google searches, and the closest thing that I've found so far is this (click), from this question. But, removing the .fadein, .delay, and .fadeout stopped the script from working entirely. I'm not by any means a pro with Ajax. Is what I'm trying to do even possible?

  • javascript array/object issue

    - by FlyingCat
    I am trying to push elements to an array. for (a=0; a < test.length; a++){ if(this.testnumber != test[a].number){ //it will only loop 8 times under conditional statement group = { title: test.Title , ID: test.ID, contents: [] }; this.company.push(group); this.testnumber = test.number[a]; } //outside of if conditional statement.. it will loop 15 times //i want every test[a].conetents get pushed to group.contents array. //this.company is the final variable I need for this function... group.contents.push(test[a].contents); } However, when I do console.log(this.company); I see 8 elmements with only 1 element in each group.contents array The ideal situation is to have 8 elements with 2 to 3 elements in the group.contents array I hope I explain my situation well. Any idea how to solve my issue? Thanks a lot!

  • How can I prevent text displacement for some foreign language fonts?

    - by weltraumpirat
    I have a multilingual project (currently 13 languages), which uses many different font variations of "Helvetica Neue", mostly bold, condensed and regular cuts from the LinoType Pro font set ( which includes western european characters) and the same for cyrillic. We will probably add chinese and japanese variations in the future. I have set up the project to use different CSS stylesheets and separately load the fonts for each version, depending on which language the user selects, so I can have different line heights, kerning and/or font sizes to make everything keep the original look, even if the fonts look nothing alike. All of this works well, except for one problem: For some reason, all cyrillic letters seem to be displaced. They appear 2-3 pixels below the correct base line, and actually protrude across the textfield's bottom border, even when the field is set to autosize. When I use textfield.getCharBoundaries(), all values seem to be correct, even though they obviously aren't rendered correctly. To make everything look neat, I could of course manually move all problematic textfields up or down according to language and font size, but I was wondering if there was some way to prevent or at least detect this kind of displacement in order to automatically handle the adjustments - the Flash Player should have some sort of information on how things are rendered, shouldn't it? Have any of you had similar problems? Or better yet: a solution?

  • Move to php in windows? Concern, hints, "please don't do!"?

    - by Daniel
    I am considering to move frome Microsoft languages to PHP (just for web dev) which has quite an interesting syntax, a perlish look (but a wider programmer base) and it allows me to reuse the web without reinventing it. I have some concerns too. I would be more than happy to gather some wisdom from stackoverflow community, (challenge to my opinions warmly welcome). Here are my doubts. Efficiency. Cgi are slow, what I am supposed to use? Fastcgi? Or what else? Efficiency + stability. Is PHP on windows really stable and a good choice in terms of performances? Database. I use very often MSSQL (I regret, i like it). Could I widely and efficiently interface PHP with MSSQL (using smartly stored pro, for example). XSLT + XML performance. I work quite a lot with XML and XSLT and I really find the MS xml parser a great software component. Are parser used in PHP fast, reliable and efficient (I am interested mainly in DOM, not SAX)? Objects. Is the PHP object programming model valid end efficient? 6 Regex. How efficient is PHP processing regexp? Many thanks for your advices.

  • Scanning, Checking, Converting, Copying values ... How to ? -- C --

    - by ZaZu
    Hi there, Its been a while now and im still trying to get a certain code to work. I asked some question about different commands etc. before, but now I hope this is the final one (combining all questions in one code). I basically want to : *Scan an input (should be character ? ) *Check if its a number *If not, return error *Convert that character into a float number *Copy the value to another variable ( I called it imp here) Here is what I came up with : #include<stdio.h> #include<stdlib.h> #include<ctype.h> main(){ int digits; float imp=0; int alpha; do{ printf("Enter input\n\n"); scanf("\n%c",&alpha); digits=isdigit(alpha); if(digits==0){ printf("error\n\n"); } imp=atof(alpha); }while(digits==0); } The problem is this code does not work at all ... It gives me that atof must be of a const char and whenever I try changing it around, it just keeps failing. I am frustrated and forced to ask here, because I believe I have tried alot and I keep failing, but I wont be relieved until I get it to work xD So I really need your help guys. Please tell me why isnt this code working, what am I doing wrong ? I am still learning C and really appreciate your help :)

  • Unit Testing the Use of TransactionScope

    - by Randolpho
    The preamble: I have designed a strongly interfaced and fully mockable data layer class that expects the business layer to create a TransactionScope when multiple calls should be included in a single transaction. The problem: I would like to unit test that my business layer makes use of a TransactionScope object when I expect it to. Unfortunately, the standard pattern for using TransactionScope is a follows: using(var scope = new TransactionScope()) { // transactional methods datalayer.InsertFoo(); datalayer.InsertBar(); scope.Complete(); } While this is a really great pattern in terms of usability for the programmer, testing that it's done seems... unpossible to me. I cannot detect that a transient object has been instantiated, let alone mock it to determine that a method was called on it. Yet my goal for coverage implies that I must. The Question: How can I go about building unit tests that ensure TransactionScope is used appropriately according to the standard pattern? Final Thoughts: I've considered a solution that would certainly provide the coverage I need, but have rejected it as overly complex and not conforming to the standard TransactionScope pattern. It involves adding a CreateTransactionScope method on my data layer object that returns an instance of TransactionScope. But because TransactionScope contains constructor logic and non-virtual methods and is therefore difficult if not impossible to mock, CreateTransactionScope would return an instance of DataLayerTransactionScope which would be a mockable facade into TransactionScope. While this might do the job it's complex and I would prefer to use the standard pattern. Is there a better way?

  • Generic Constraints And Type Parameters Mess

    - by Dummy01
    Hi everyone, I have the following base abstract class defined as: public abstract class BaseObject<T> : IComparable, IComparable<T>, IEquatable<T> {} I also have an interface defined as: public interface ICode<T> where T : struct { T Code { get; } } Now I want to derive a class that is inherited from BaseObject<T> and includes interface ICode<T>. I tried to define it like that: public class DerivedObject<T, U> : BaseObject<T>, ICode<U> where T : DerivedObject<T, U> where U : struct { public DerivedObject(U code) { Code = code; } // From BaseObject protected override int InstanceCompareTo(T obj) { return Code.CompareTo(obj.Code); } // From BaseObject protected override bool InstanceEquals(T obj) { return Code.Equals(obj.Code); } // From ICode U _Code; public U Code { get { return _Code; } protected set { _Code = value; } } } The only error that comes from the compiler is for Code.CompareTo(obj.Code) with the message: 'U' does not contain a definition for 'CompareTo' and no extension method 'CompareTo' accepting a first argument of type 'U' could be found. But U is a value type and should know CompareTo. Have you any idea what I am doing wrong, or if I do all wrong? My final aim is to derive classes such these: public class Account : DerivedObject<Account, int> public class ItemGroup : DerivedObject<ItemGroup, string> Big Thanks In Advance!

  • C# and Objects/Classes

    - by user1192890
    I have tried to compile code from Deitel's C# 2010 for programmers. I copied it exactly out of the book, but it still can't find main, even though I declared it in one of the classes. Here is a look at the two classes: For GradeBookTest: // Fig. 4.2: GradeBookTest.cs // Create a GradeBook object and call its DisplayMessage method. public class GradeBookTest { // Main method begins program execution public static void Main(string[] args) { // create a GradeBook object and assign it to myGradeBook GradeBook myGradeBook = new GradeBook(); // call myGradeBook's DisplayMessage method myGradeBook.DisplayMessage(); } // end Main } // end class GradeBookTest Now for the GradeBook class: // Fig. 4.1: GradeBook.cs // Class declaration with one method. using System; public class GradeBook { // display a welcome message to the GradeBook user public void DisplayMessage() { Console.WriteLine( "Welcome to the Grade Book!" ); } // end method DisplayMessage } // end class GradeBook That is how I copied them. Here is how they appeared in the book: 1 // Fig. 4.2: GradeBookTest.cs 2 // Create a GradeBook object and call its DisplayMessage method. 3 public class GradeBookTest 4 { 5 // Main method begins program execution 6 public static void Main( string[] args ) 7 { 8 // create a GradeBook object and assign it to myGradeBook 9 GradeBook myGradeBook = new GradeBook(); 10 11 // call myGradeBook's DisplayMessage method 12 myGradeBook.DisplayMessage(); 13 } // end Main 14 } // end class GradeBookTest and // Fig. 4.1: GradeBook.cs // Class declaration with one method. using System; public class GradeBook { // display a welcome message to the GradeBook user public void DisplayMessage() { Console.WriteLine( "Welcome to the Grade Book!" ); } // end method DisplayMessage } // end class GradeBook I don't see why they are not working. Right now I am using Visual Studio Pro 2010. Any Thoughts?

  • Why does my SQL database not work in Android?

    - by user1426967
    In my app a click on an image button brings you to the gallery. After clicking on an image I want to call onActivityResult to store the image path. But it does not work. In my LogCat it always tells me that it crashes when it tries to save the image path. Can you find the problem? My onActivityResult method: mImageRowId = savedInstanceState != null ? savedInstanceState.getLong(ImageAdapter.KEY_ROWID) : null; @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if(requestCode == PICK_FROM_FILE && data != null && data.getData() != null) { Uri uri = data.getData(); if(uri != null) { Cursor cursor = getContentResolver().query(uri, new String[] { android.provider.MediaStore.Images.ImageColumns.DATA}, null, null, null); cursor.moveToFirst(); String image = cursor.getString(0); cursor.close(); if(image != null) { // HERE IS WHERE I WANT TO SAVE THE IMAGE. HERE MUST BE THE ERROR! if (mImageRowId == null) { long id = mImageHelper.createImage(image); if (id > 0) { mImageRowId = id; } } // Set the image and display it in the edit activity Bitmap bitmap = BitmapFactory.decodeFile(image); mImageButton.setImageBitmap(bitmap); } } } } This is my onSaveInstanceState method: private static final Long DEF_ROW_ID = 0L; @Override protected void onSaveInstanceState(Bundle outState) { outState.putLong(ImageAdapter.KEY_ROWID, mImageRowId != null ? mImageRowId : DEF_ROW_ID); super.onSaveInstanceState(outState); } This is a part from my DbAdapter: public long createImage(String image) { ContentValues cv = new ContentValues(); cv.put(KEY_IMAGE, image); return mImageDb.insert(DATABASE_TABLE, null, cv); }

  • Need a piece of advice about e-mail automation in ms exchange + ms office environment

    - by be here now
    Hi, guys. I need your help in the following simple situation. I've got an MS Exchange server and some client computers running on XP with Office 2003 installed. And I've got a process I need to automate. Twice a day a known list of people sends an e-mail to a certain mailbox (let's call it manager's mailbox) - basically, an accomplishment report. After recieving letters from all of these people the mailbox owner sends and e-mail to another mailbox, meaning that a certain process is done. What I need to do is to replace this manager's mailbox with a depersonalized mailbox that will accumulate all the reports and automatically send a message after collecting all of them. I am definitely not in a "oh my God, what shold I do?" situation, and currently my imagination shows me a couple of ways to solve this problem, which I'm going to try, and I'm not ascking for a ready solution. But since I'm not experienced in Office/VBA developement, I'd like to ask a corresponding pro's opinion. Can you point me to a right direction from the best practices' point of view?

  • How to use clearInterval() and then make changes to the DOM?

    - by George D.
    I have this code and the problem I have is that I want to stop the loop and then replace the text 'Done!' that comes from the sms-loader.php script with the "textnew" string. Problem is that the loop occurs one more time so the text in the div.checkstatus field is again replaced by the calling php script. The strange thing is that I see the log message and again I get a new (and final) request, although the ordering is the opposite (first stop then replace text()) in my script. I need to understand why this is happening. $(document).ready(function() { var interval = ""; $('.checkstatus').each(function(){ var msgid = $(this).data('msg') $this = $(this), hid = $this.data('history'), textnew = '<a href="sms-dstatus.php?id='+msgid+'&sid=' +hid+ '&amp;keepThis=true&amp;TB_iframe=true&amp;height=430&amp;width=770" title="Delivery Status" class="thickbox"><img src="../template/icons/supermini/chart_curve.png" alt="status" width="16" height="16" /></a>'; interval = setInterval(function() { $this.load('../pages/sms-loader.php?id='+msgid); // stop the loop if($this.text()=='Done!'){ // stop it clearInterval(interval); console.log(textnew); this.html(textnew); /// this line is the problem } }, 5000); // 5 secs }); });

  • Are you using C++0x today? [closed]

    - by Roger Pate
    This is a question in two parts, the first is the most important and concerns now: Are you following the design and evolution of C++0x? What blogs, newsgroups, committee papers, and other resources do you follow? Even where you're not using any new features, how have they affected your current choices? What new features are you using now, either in production or otherwise? The second part is a follow-up, concerning the new standard once it is final: Do you expect to use it immediately? What are you doing to prepare for C++0x, other than as listed for the previous questions? Obviously, compiler support must be there, but there's still co-workers, ancillary tools, and other factors to consider. What will most affect your adoption? Edit: The original really was too argumentative; however, I'm still interested in the underlying question, so I've tried to clean it up and hopefully make it acceptable. This seems a much better avenue than duplicating—even though some answers responded to the argumentative tone, they still apply to the extent that they addressed the questions, and all answers are community property to be cleaned up as appropriate, too.

  • How can I bind to a helper property in Silverlight

    - by Matt
    For the sake of argument, here's a simple person class public class Person : DependencyObject, INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; public static readonly DependencyProperty FirstNameProperty = DependencyProperty.Register( "FirstName", typeof ( string ), typeof ( Person ), null ); public static readonly DependencyProperty LastNameProperty = DependencyProperty.Register( "LastName", typeof( string ), typeof( Person ), null ); public string FirstName { get { return ( string ) GetValue( FirstNameProperty ); } set { SetValue( FirstNameProperty, value ); if(PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs( "FirstName" )); } } public string LastName { get { return ( string ) GetValue( LastNameProperty ); } set { SetValue( LastNameProperty, value ); if ( PropertyChanged != null ) PropertyChanged( this, new PropertyChangedEventArgs( "LastName" ) ); } } } I want to go about creating a readonly property like this public string FullName { get { return FirstName + " " + LastName; } } How does binding work in this scenario? I've tried adding a DependancyProperty and raised the PropertyChanged event for the fullname. Basically I just want to have a property that I can bind to that returns the fullname of a user whenever the first or last name changes. Here's the final class I'm using with the modifications. public class Person : DependencyObject, INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; public static readonly DependencyProperty FirstNameProperty = DependencyProperty.Register( "FirstName", typeof ( string ), typeof ( Person ), null ); public static readonly DependencyProperty LastNameProperty = DependencyProperty.Register( "LastName", typeof( string ), typeof( Person ), null ); public static readonly DependencyProperty FullNameProperty = DependencyProperty.Register( "FullName", typeof( string ), typeof( Person ), null ); public string FirstName { get { return ( string ) GetValue( FirstNameProperty ); } set { SetValue( FirstNameProperty, value ); if ( PropertyChanged != null ) { PropertyChanged( this, new PropertyChangedEventArgs( "FirstName" ) ); PropertyChanged( this, new PropertyChangedEventArgs( "FullName" ) ); } } } public string LastName { get { return ( string ) GetValue( LastNameProperty ); } set { SetValue( LastNameProperty, value ); if ( PropertyChanged != null ) { PropertyChanged( this, new PropertyChangedEventArgs( "LastName" ) ); PropertyChanged( this, new PropertyChangedEventArgs( "FullName" ) ); } } } public string FullName { get { return GetValue( FirstNameProperty ) + " " + GetValue( LastNameProperty ); } } }

  • Division of text follow the cursor via Javascript/Jquery

    - by webzide
    Dear experts, I wanted have a dynamic division of content follow you with the cursor in the web browser space. I am not a pro at JS so I spent 2 hours to finally debugged a very stupid way to accomplish this. $(document).ready(function () { function func(evt) { var evt = (evt) ? evt : event; var div = document.createElement('div'); div.style.position = "absolute"; div.style.left = evt.clientX + "px"; div.style.top = evt.clientY + "px"; $(div).attr("id", "current") div.innerHTML = "CURSOR FOLLOW TEXT"; $(this).append($(div)); $(this).unbind() $(this).bind('mousemove', function () { $('div').remove("#current"); }); $(this).bind('mousemove', func); } $("body").bind('mousemove', func) }); As you can see this is pretty much Brute force and it slows down the browser quite a bit. I often experience a lag on the browser as a drag my mouse from one place to another. Is there a way to accomplish this easier and faster and more intuitive. I know you can use the cursor image technique but thats something I'm looking to avoid. Thanks in advance.

  • rails 3 actionmailer cannot send email

    I am following Ryan Bates's tutorial on Rails 3 ActionMailer. I generate the mailer in terminal and then establish a setup_mail.rb under config/initializers.

  • Java for loop with multiple incrementers

    - by user2517280
    Im writing a program which combines the RGB pixel values for 3 images, e.g. red pixel of image 1, green pixel of image 2 and blue pixel of image 3 and I want to then create a final image of it. Im using the code below, but this seems to be incrementing x2 and x3 whilst x1 is the same, i.e. not giving the right pixel value for same co-ordinate for each image. for (int x = 0; x < image.getWidth(); x++) { for (int x2 = 0; x2 < image2.getWidth(); x2++) { for (int x3 = 0; x3 < image3.getWidth(); x3++) { for (int y = 0; y < image.getHeight(); y++) { for (int y2 = 0; y2 < image2.getHeight(); y2++) { for (int y3 = 0; y3 < image3.getHeight(); y3++) { So I was wondering if anyone can tell me how to iterate through each of the 3 images on the same co-ordinate, so for example read 1, 1 of each image and record the red, green and blue value accordingly. Apologies if it doesnt make complete sense, its a bit hard to explain. I can iterate the values for one image fine but when I add in another, things start to go a bit wrong as obviously its quite a bit more complicated! I was thinking it might be easier to create an array and replace the according values in that just not sure how to do that effectively either. Thanks

  • Creating and parsing huge strings with javascript?

    - by user246114
    Hi, I have a simple piece of data that I'm storing on a server, as a plain string. It is kind of ridiculous, but it looks like this: name|date|grade|description|name|date|grade|description|repeat for a long time this string can be up to 1.4mb in size. The idea is that it's a bunch of student records, just strung together with a simple pipe delimeter. It's a very poor serialization method. Once this massive string is pushed to the client, it is split along the pipes into student records again, using javascript. I've been timing how long it takes to create, and split, these strings on the client side. The times are actually quite good, the slowest run I've seen on a few different machines is 0.2 seconds for 10,000 'student records', which has a final string size of ~1.4mb. I realize this is quite bizarre, just wondering if there are any inherent problems with creating and splitting such large strings using javascript? I don't know how different browsers implement their javascript engines. I've tried this on the 'major' browsers, but don't know how this would perform on earlier versions of each. Yeah looking for any comments on this, this is more for fun than anything else! Thanks

  • Trying to get codeblocks working on Mac, running Lion. Can't get the compiler set up properly

    - by tjtoml
    First off, sorry if this is a stupid question. I installed code::blocks to try and get to know the program and start working on teaching myself c++. I have a MacBook Pro with OS 10.7.3. I ave code::blocks 10.05. When I try to build a "Hello world" nothing happens. Based on some googling I've figured out that it's because code::blocks doesn't know where to find the debugger/compiler. Further googling yielded me this page which tells me to install Xcode and to fix some things in the code::blocks settings. However, this wiki obviously has not been updated since Apple went to the App store, because the file paths it gives for the compiler do not exist (there is no /Developer/* even after installing Xcode). Xcode 4.3.2 was already installed when I installed code::blocks and code::blocks "auto-detected" several compilers. They did not work. If anyone knows where Xcode hides its compilers now that Apple has moved to the app store, I would be much obliged.

  • Can Haskell's monads be thought of as using and returning a hidden state parameter?

    - by AJM
    I don't understand the exact algebra and theory behind Haskell's monads. However, when I think about functional programming in general I get the impression that state would be modelled by taking an initial state and generating a copy of it to represent the next state. This is like when one list is appended to another; neither list gets modified, but a third list is created and returned. Is it therefore valid to think of monadic operations as implicitly taking an initial state object as a parameter and implicitly returning a final state object? These state objects would be hidden so that the programmer doesn't have to worry about them and to control how they gets accessed. So, the programmer would not try to copy the object representing the IO stream as it was ten minutes ago. In other words, if we have this code: main = do putStrLn "Enter your name:" name <- getLine putStrLn ( "Hello " ++ name ) ...is it OK to think of the IO monad and the "do" syntax as representing this style of code? putStrLn :: IOState -> String -> IOState getLine :: IOState -> (IOState, String) main :: IOState -> IOState -- main returns an IOState we can call "state3" main state0 = putStrLn state2 ("Hello " ++ name) where (state2, name) = getLine state1 state1 = putStrLn state0 "Enter your name:"

  • some problem with iOS 4.2.1

    - by bicbac
    Hi, I've been developing an app with MacBook Pro (MBP) so far. Last week one of my friends gave me new macbook air 11"(MBA). so Now I can test my code with more than one machine with the same version of developing tools - Both machine has Xcode (3.2.5) and iOS SDK 4.2.1). After some point my app starts get terminated suddenly(iPhone sumulator), and I was using MBP. I got no error message whatsoever. it just stops. I reckon the crash comes from dealing with memory, like 'release'/ 'double-release'. (I'm not 100% sure though). Anyway I thought there must be some mistake within my code for sure. -Confusion starts from this part.- With my MBA, on the other hand, I don'y see any crash. It just works fine. There is nothing different between MBA & MBP except the h/w specifications. Same code, same versions of XCode and iOS SDK. Is the fact that no crash at MBA suggesting that I have to look somewhere else than the code itself? I red some article and Q&As on iOS4.2.1 and XCode 3.2.5 that the most recent version of XCode doesn't recognize the iOS 4.2.1 since the 4.2.1 came out later the 3.2.5. Is it the reason? I have no idea at this moment what should be the next move. thanks

  • Raspberry Pi broadcast serial port data to local network

    - by D051P0
    I didn't find anything to help me with this problem. What I want is: Serial device sends repeatedly some data to serial port. Raspberry Pi should get this data from RxD and stream it to local network via port 10001 without filtering it. So I can find this device on my pc. This should also work in other direction: Raspberry listen to port 10001 and forward all data from local network to TxD. I'm newbie in Linux World. How can I listen to some port on Raspberry Pi and send broadcast to the same port? I'm using Raspbian Wheezy with soft float. I have found a library Pi4j for Java, that I already use to get and write data from/to serial port. final Serial serial = SerialFactory.createInstance(); serial.addListener(new SerialDataListener() { public void dataReceived(SerialDataEvent event) { forward(event.getData()); } }); event.getData() is a String, which I want to broadcast in my local network. Is it generally a good Idea to use Java for that? I need also a String from port 10001, which I can forward to serial port.

  • Visual Studio 2008 linker wants all symbols to be resolved, not only used ones

    - by user343011
    We recently upgraded to Visual Studio 2008 from 2005, and I think those error started after that. In our solution, we have a multitude of projects. Many of those are utility projects, or projects containing core functionality used by other projects. The output of those is lib files that are linked to when building the projects generating the final binaries using the "Project dependencies..." option. One of the other projects---Let us call it ResultLib---generates a DLL, and it needs one single function from the core project. This function uses only static function from its own source file, but the project in its entirety uses a lot of low-level Windows functions and also imports a DLL---Let us call it Driver.dll. Our problem is that when building ExtLib, the linker complains about a multitude of unresolved externals, for example all functions exported from Driver.dll, since its lib file is not specified when linking. If we try to fix this by adding all lib files used by other projects that use all of the core project, our resulting ResultLib DLL ends up importing Driver.dll and also exporting all functions defined in it. How do we tell Visual Studio to only try to resolve symbols that are actually used?

  • drawing graphs in php

    - by user434885
    i am using php to generate graphs from arrays. I wish to create multiple graphs on the same page as i need to design a summary report from answers extracted from a database. Currently i am using this code and am only able to get one single graph. what additions to the code do i need to make to get multiple graphs? <?php function draw_graph($values) { // Get the total number of columns we are going to plot $columns = count($values); // Get the height and width of the final image $width = 300; $height = 200; // Set the amount of space between each column $padding = 5; // Get the width of 1 column $column_width = $width / $columns ; // Generate the image variables $im = imagecreate($width,$height); $gray = imagecolorallocate ($im,0xcc,0xcc,0xcc); $gray_lite = imagecolorallocate ($im,0xee,0xee,0xee); $gray_dark = imagecolorallocate ($im,0x7f,0x7f,0x7f); $white = imagecolorallocate ($im,0xff,0xff,0xff); // Fill in the background of the image imagefilledrectangle($im,0,0,$width,$height,$white); $maxv = 0; // Calculate the maximum value we are going to plot for($i=0;$i<$columns;$i++)$maxv = max($values[$i],$maxv); // Now plot each column for($i=0;$i<$columns;$i++) { $column_height = ($height / 100) * (( $values[$i] / $maxv) *100); $x1 = $i*$column_width; $y1 = $height-$column_height; $x2 = (($i+1)*$column_width)-$padding; $y2 = $height; imagefilledrectangle($im,$x1,$y1,$x2,$y2,$gray_dark); } header ("Content-type: image/png"); imagepng($im); imagedestroy($im); } $values = array("23","32","35","57","12"); $values2 = array("123","232","335","157","102"); draw_graph($values2); draw_graph($values);//no output is coming draw_graph($values2);//no output is coming draw_graph($values);//no output is coming ?>
