  • Simulate mouse movement in Ubuntu

    - by Dave Jarvis
    Problem Am looking to automatically move the mouse cursor and simulate mouse button clicks from the command-line using an external script. Am not looking to: Record mouse movement and playback (e.g., xnee, xmacro) Instantly move the mouse from one location to another (e.g., xdotool, Python's warp_pointer) Ideal Solution What I'd like to do is the following: Edit a simple script file (e.g., mouse-script.txt). Add a list of coordinates, movement speeds, delays, and button clicks. For example: (x, y, rate) = (500, 500, 50) sleep = 5 click = left Run the script: xsim < mouse-script.txt. Question How do you automate mouse movement so that it transitions from its current location to another spot on the screen, at a specific velocity? For example: xdotool mousemove 500 500 --rate 50 The --rate 50 doesn't exist with xdotool. I could write a script that uses xdotool to get the current mouse coordinates then move it a pixel at a time to the destination with a suitable sleep interval; what automated testing tool already does this? Thank you.

  • Updating multiple divs w/ RJS/AJAX

    - by bgadoci
    I am successfully using RJS to implement AJAX on a page.replace.html create.js.rjs. I am attempting to update two locations instead of one and after watching Ryan Bates Railscast I am very close (I think) but have a problem in the syntax of my /views/likes/create.js.rjs file. Here is the situation: located at /views/likes/create.js.rjs is the following code: page.replace_html "votes_#{ @site.id }", :partial => @like page.replace_html "counter", 10 - (@question.likes.count :conditions => {:user_id => current_user.id}) page[@like].visual_effect :highlight My problem lies in the second line. The div "counter" displays the following code in the /views/question/show.html.erb page: <div id="counter"> You have <%= 10 - (@question.likes.count :conditions => {:user_id => current_user.id}) %> votes remaining for this question </div> From watching the screen cast I believe that my error has to do w/ the syntax of the second line. Specifically he mentions that you cannot use a local instance variable but not sure how to make the change. Thoughts?

  • PHP mySQL Error

    - by happyCoding25
    Hello, Im new to php so I decided to follow this tutorial for a simple login screen. I got the code setup but when I try login I get this error: Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in (a long file path to the script) on line 27 The code I got from the tutorial is: <?php ob_start(); $host="thehost"; // Host name $username="myusername"; // Mysql username $password="mypass"; // Mysql password $db_name="test"; // Database name $tbl_name="members"; // Table name // Connect to server and select databse. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); // Define $myusername and $mypassword $myusername=$_POST['myusername']; $mypassword=$_POST['mypassword']; // To protect MySQL injection (more detail about MySQL injection) $myusername = stripslashes($myusername); $mypassword = stripslashes($mypassword); $myusername = mysql_real_escape_string($myusername); $mypassword = mysql_real_escape_string($mypassword); $sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'"; $result=mysql_query($sql); // Mysql_num_row is counting table row $count=mysql_num_rows($result); // If result matched $myusername and $mypassword, table row must be 1 row if($count==1){ // Register $myusername, $mypassword and redirect to file "login_success.php" session_register("myusername"); session_register("mypassword"); header("location:login_success.php"); } else { echo "Wrong Username or Password"; } ob_end_flush(); ?> (Note: All of the mySQL database info is filled in on my version) Aslo, the author gives a php5 version and a normal php version. I have tried both and gotten the same error. If anyone knows why this is happening help is really appreciated.

  • BitBlting multiple images to buffer

    - by Anonymous
    So I've made a class which draws a transparant image to a buffer. the buffer is a HDC which has been used blackness on. What I am trying to do is draw three images to this buffer. Which means I am using this function three times. After that's done, I output it to the screen (using SRCCOPYing the buffer). But what I get to see is just the third image and blackness. void draw_buffer(HDC buffer, int draw_x, int draw_y) { BitBlt(this-main, draw_x, draw_y, this-img_width, this-img_height, this-image, this-mask_x, this-mask_y, SRCAND); BitBlt(this-main, draw_x, draw_y, this-img_width, this-img_height, this-image, this-img_x, this-img_y, SRCPAINT); BitBlt(buffer, 0, 0, 800, 600, this-main, 0, 0, SRCCOPY); } At initiation, this-main becomes this: this->main = CreateCompatibleDC(GetDC(0)); this->bitmap = CreateCompatibleBitmap(GetDC(0),800,600); SelectObject(this->main, this->bitmap); What is wrong with my code?

  • Make winform run away from the mouse.

    - by JACK IN THE CRACK
    Okay so I'm trying to make a little gag program that will "run away" from the mouse. So, to get the mouse coordinates for the whole screen and not just the form control I had to create a little helper: static class MouseHelper { [DllImport("user32.dll")] [return: MarshalAs(UnmanagedType.Bool)] internal static extern bool GetCursorPos(ref Point pt); public static Point GetPosition() { Point w32Mouse = new Point(); GetCursorPos(ref w32Mouse); return w32Mouse; } } Now I thought I was going to use the MouseMove event... but that doesn't work for outside the form control either so I have an auto-enabled timer on a 10ms loop called timerMouseMove. public partial class Form1 : Form { public Form1() { InitializeComponent(); } private bool CollisionCheck() { Point win32Mouse = MouseHelper.GetPosition(); if (win32Mouse.X <= Location.X || win32Mouse.X >= (Location.X + Width)) return false; if (win32Mouse.Y <= Location.Y || win32Mouse.Y >= (Location.Y + Height)) return false; return true; } private void timerMouseMove_Tick(object sender, EventArgs e) { if (CollisionCheck()) Location = new Point(Location.X + 1, Location.Y + 1); } } So this works out nicely, at least I have the collision checking working and whatnot. But now, how should I go about figuring which side of the form the mouse has collided with, so that I can update its location to move in the opposite direction the mouse collides with it? And such halp

  • GridView: How can I get rid of extra space from my GirdView object?

    - by Lajos Arpad
    Hello, I'm writing an application for Android phones for Human vs. Human chess play over the internet. I was looking at some tutorials, to learn how to develop Android applications and found a very nice example of making galleries (it was a GridView usage example for making a gallery about dogs) and the idea came to draw the chess table using a GridView, because the example project also handled the point & click event and I intended to use the same event in the same way, but for a different purpose. The game works well (currently it's a hotseat version), however, I'm really frustrated by the fact that whenever I rotate the screen of the phone, my GridView gets hysterical and puts some empty space in my chess table between the columns. I realized that the cause of this is that the GridView's width is the same as its parent's and the GridView tries to fill its parent in with, but there should (and probably is) be a simple solution to get rid of this problem. However, after a full day of researching, I haven't found any clue to help me to make a perfect drawing about my chess table without a negative side effect in functionality. The chess table looks fine if the phone is in Portrait mode, but in Landscape mode it's far from nice. This is how I can decide whether we are in Portrait or Landscape mode: ((((MainActivity)mContext).getWindow().getWindowManager().getDefaultDisplay().getWidth()) < ((MainActivity)mContext).getWindow().getWindowManager().getDefaultDisplay().getHeight()) In the main.xml file the GridView is defined in the following way: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <GridView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/gridview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:numColumns="8" android:verticalSpacing="0dp" android:horizontalSpacing="0dp" android:stretchMode="columnWidth" android:gravity="center" > </GridView> ... </LinearLayout> I appreciate any help with the problem and thank you for reading this.

  • IPhone SDK - Leaking Memory with performSelectorInBackground

    - by Steblo
    Hi. Maybe someone can help me with this strange thing: If a user clicks on a button, a new UITableView is pushed to the navigation controller. This new view is doing some database querying which takes some time. Therefore I wanted to do the loading in background. What works WITHOUT leaking memory (but freezes the screen until everything is done): WorkController *tmp=[[WorkController alloc] initWithStyle:UITableViewStyleGrouped]; self.workController=tmp; [tmp release]; [self.workController loadList]; // Does the DB Query [self.workController pushViewController:self.workController animated:YES]; Now I tried to do this: // Show Wait indicator .... WorkController *tmp=[[WorkController alloc] initWithStyle:UITableViewStyleGrouped]; self.workController=tmp; [tmp release]; [self performSelectorInBackground:@selector(getController) withObject:nil]; } -(void) getController { [self.workController loadList]; // Does the DB Query [self.navigationController pushViewController:self.workController animated:YES]; } This also works but is leaking memory and I don't know why ! Can you help ? By the way - is it possible for an App to get into AppStore with a small memory leak ? Or will this be checked first of all ? Thanks in advance !

  • SubSonic 3 screws up selecteditem?

    - by SteveCav
    If you have a moment, please try this: -Download Subsonic 3. -Start a new proj and add SS's ActiveRecord templates. -Point it to any SQL Server DB and generate the classes. -Add a WPF project. -Create a window and add a combobox or listbox. -Set the ItemsSource from the SS DAL, and format it how you wish. -Add a button that will show you some value from the SelectedItem (using messagebox, console, whatever). -Run the project. -Click on the third item in the list. -Click on the second item in the list. -Click on the button. When I do that, the button gives me the value of the THIRD item, not the second. In other words, once the SelectedItem is set the first time it STAYS, no matter which item is subsequently highlighted on the screen. This is happening to me whatever control I use (combobox, listbox, even datagrid) and it ONLY happens with Subsonic Activerecord objects. If I write my own POCOs with identical properties and bind a list of them instead, the controls behave as expected. Does this happen to you? Any ideas?

  • How to make a small flash swf with ComboBox in Actionscript 3?

    - by Sint
    I have a pure Actionscript 3 project, using flash.* libraries, compiles down to about 6k (using mxmlc). Program handles about 1k shapes, a few sprites, a sockets connection, works great (tastes less filling). Now, how would I add a ComboBox control without incurring excessive bloat? More specificially, I would like to keep the size under 100k. So far I have tried: Adobe mx.controls ComboBoxexample - simple mxml example compiles to 200+k both on my main Linux Box using mxmlc and in Windows using Flash Builder 4 Yahoo Astra - uses mx libraries underneath(so as bloated as Adobe?), plus does not contain exact ComboBox Keith Peter's MinimalComps - seems small, but far from providing ComboBox functionality SPAS (Swing Package for Actionscript) - compiles to 130k, but alpha version of ComboBox does not let me adjust height... asuilib - compiles to 40k, unfortunately this ComboBox does not provide for scrolling items...if it does not fit on screen no way to scroll to it Now my questions: Is there a way to lower size for projects importing mx.controls ? Maybe there is a way to fix SPAS or asuilib ComboBoxes? Perhaps, there are some other libraries which provide a ComboBox(or DropList)?

  • How can I round money values to the nearest $5.00 interval?

    - by Frank Developer
    I have an Informix-SQL based Pawnshop app which calculates an estimate of how much money should be loaned to a customer, based on the weight and purity of gold. The minimum the pawnshop lends is $5.00. The pawnshop employee will typically lend amounts which either ends with a 5 or 0. examples: 10, 15, 20, 100, 110, 125, etc. They do this so as to not run into shortage problems with $1.00 bills. So, if for example my system calculates the loan should be: $12.49, then round it to $10, $12.50 to $15.00, $13.00 to $15.00, $17.50 to $20.00, and so on!..The employee can always override the rounded amount if necessary. Is it possible to accomplish this within the instructions section of a perform screen or would I have to write a cfunc and call it from within perform?.. Are there any C library functions which perform interval rounding of money values?.. On another note, I think the U.S. Government should discontinue the use of pennies so that businesses can round amounts to the nearest nickel, it would save so much time and weight in our pockets!

  • Straw Poll - K&R vs BSD

    - by Gordon Mackie JoanMiro
    No holy wars please - (ultimately a standardised and consistently-observed house-style on a project always wins out whatever is chosen), but I am genuinely interested in the preferences of people for K&R style formatting: public bool CompareObjects(object first, object second) { if (first == second) { return true; } else { return false; } } over BSD style: public bool CompareObjects(object first, object second) { if (first == second) { return true; } else { return false; } } K&R seems to be making a bit of a comeback recently (I'm an old programmer, so I've seen these things fluctuate); do people think K&R looks more professional, more cool, more readable, is compactness when viewing more important than extending the structure down the screen? Please use the 2 community wiki answers below to vote for K&R vs. BSD. Polls shouldn't earn rep for the first person that manages to type "BSD FTW!" My God! This question is nearly 2 years old and people are still down-voting it; ENOUGH!

  • ArrayAdapter and android:textFilterEnabled

    - by TiGer
    Hi there, I have created a layout which includes a ListView... The data shown within this ListView isn't too complicated, it's mostly an Array which is passed when the extended Activity is started... The rows themselves exist out of an icon and a text, thus an ImageView and a TextView... To fill up the ListView I use an ArrayAdapter simply because an Array is passed containing all the text-items that should be shown.. Now I'd like to actually be able to filter those, thus I found the android:textFilterEnabled paramater to add on the ListView xml declaration... Now a search field is shown nicely but when I enter some letters it won't filter but it will simply delete the whole list... I found out that that's because the textfilter has no idea what it should filter... So now my question is : I know I need to tell the textfilter what it should filter, I also still have my array filled with the text that should get filtered so how do i couple those two ??? I have seen examples extending a CursorAdapter, but again, I don't have a Cursor, I don't want to do calls to a DB I want to re-utilize my Array with data and obviously the ArrayAdapter itself so that the data will be represented decently on screen (i.e with my ImageView and TextView layout)... Thanks in advance for any help/pointers/tips/code...

  • Full Text Index type column is empty

    - by RemotecUk
    I am trying to create an index on a VarBinary(max) field in my SQL Server 2008 database. The steps I am taking are as follows: Table: dbo.Records Right click on table and select "Full Text Index" Then select "Define Index..." I choose the primary key which is the PK of my table (field name Id, type UniqueIndentifier). I then get the screen with the options Available Columns, Language for Word Breaker and Type Column I select my VarBinary(max) field called Chart as the Available Column by ticking the box. I select "English" as the Language for Word Breaker field. Then... I try to select the Type Column but there are no entries in here. I cannot proceed by clicking "Next" until this column is populated. Why are there no entries in this column for selection and what should be in there? Note 1: The VarBinary(max) field is linked to a file group if that makes any difference. Note 2: Also noticed that in the table designer I cannot set the full text option on that same field to "Yes" - its permanently stuck on "No". Thanks.

  • CSS Hover on parent list Item only

    - by Daniel O'Connor
    Hey Everyone, So I have some nested lists (only one level deep) and I'm running into trouble with the CSS :hover feature. I only want the hover to apply to the parent class, but I can't figure that one out. Here's my CSS <style type="text/css" media="screen"> .listblock li img { visibility: hidden; } .listblock li:hover img { visibility: visible; } </style> And here is a sample of one of the lists. <ul> <li>One <a href="#"><img src="img/basket.png" height="16" width="16" alt="Buy" class="buy" onClick="pageTracker._trackEvent('Outbound Links', 'Amazon');"/></a></li> <li>Two <a href="#"><img src="img/basket.png" height="16" width="16" class="buy" /></a> <ul> <li>Uno<a href="#"><img src="img/basket.png" height="16" width="16" class="buy" /></a></li> <li>Dos <a href="#"><img src="img/basket.png" height="16" width="16" class="buy" /></a></li> </ul> </li> <li>Three <a href="#"><img src="img/basket.png" height="16" width="16" alt="Buy" class="buy" onClick="pageTracker._trackEvent('Outbound Links', 'Amazon');"/></a></li> </ul> The problem is that the image in the Uno and Dos list items also hovers. :( Help please! Thanks a lot

  • Qt moc failure without an error message

    - by Robert Parker
    So I'm pretty new to Qt, and I've just inherited a project from someone else who is also new to Qt. He isn't around this week btw. We are using Visual Studio 2008, and have the latest version of Qt installed(4.6.2). The project builds on my coworker's machine fine, and I can get the project from svn and build it directly. But under any other circumstances it refuses to build on my machine, and it doesn't give me much of an explanation why. Even if I just do a 'build clean' and then a 'build' it doesn't work. Any slight modification will make it fail. When I try to build the entire project I get the error message: 1Moc'ing MatrixTypeInterface.h... 1moc: Cannot create .\GeneratedFiles\Debug\moc_MatrixTypeInterface.cpp;.\GeneratedFiles\Debug\moc_matrixtypeinterface.cpp 1Project : error PRJ0019: A tool returned an error code from "Moc'ing MatrixTypeInterface.h..." The moc tool doesn't give any sort of error message as to why it isn't working, and I wasted most of yesterday trying to figure out why. I got the command that VS was using to call moc, and I entered in the command line myself. It didn't write anything to the screen. Any ideas?

  • iPod touch debugging: Error on install/run only if app exists on device already?

    - by Ben
    Hi all, I am using an iPod to test an app. The device is all set up with the right provisioning profiles, etc-- that's not really the issue. But every time I start the app from Xcode on the device, I get the "A signed resource has been added, modified, or deleted." error from the Organizer window. Wait, I know, you think it's a provisioning profile problem. But here's the kicker: if I just delete the app from the iPod (using the main screen) and try again, it works fine. I only get this error when the app is already installed. The other kicker is that this behavior doesn't happen on an iPhone that I have for occasional testing-- on that device, I can start/restart/restart indefinitely. But using the iPod, my compile-run-test cycle is annoyingly slow since I have to manually delete the app each time. Any ideas? I'm using Xcode 3.2.2 (prerelease) FWIW. The iPod has stock OS 3.1.2 on it. Thanks!

  • Pinyin Character entry on a touchscreen keyboard

    - by mmr
    The app I'm developing requires that it be deployed in China, which means that it needs to have Pinyin and Chinese character handling. I'm told that the way that our customers handle character entry is like so: Enter in the pinyin character, like 'zhang' As they enter the characters, a list of possible Chinese (Mandarin?) characters are presented to the user, like: The user will then select '1' to enter the family name that is roughly translated to 'zhang' How can I hook such programs (I believe one is called 'mspy.exe', from Microsoft, which I'm lead to believe comes with Microsoft versions of XP) into a WPF text box? Right now, the user can enter text either by using their keyboard or by using an on-screen keyboard, so I will probably need to capture the event of a keypress from either source and feed it to some OS event or to MSPY.exe or some similar program. Or is there some other way to enter pinyin and have it converted to Mandarin? Is there a program other than MSPY I should look at? EDIT: For those of you who think that this should 'just work', it does not. Chinese character entry will work just fine if entering text into notepad or the start-run menu or whatever, but it will not work in WPF. That's the key to this question: how do I enable WPF entry? There's the Google Pinyin and Sogou pinyin, but the websites are in Mandarin or Chinese or something similar and I don't read the language.

  • Configuring Displays for Different Mobile Devices

    - by Mike
    Does anyone know a way to have specific CSS style sheets based on the type of Mobile Device? I have been researching it a few days now and haven't found anything except this snippet of code for iPhones. <link media="only screen and (max-device-width: 480px)" href="iPhone.css" type="text/css" rel="stylesheet" /> This works great for iPhones, but on all other mobile devices (android, blackberry, Nokia), it's still displaying the same as my site. I tried: <link media="handheld" href="iPhone.css" type="text/css" rel="stylesheet" /> but that didn't seem to have any effect on the other mobile devices. So I'm not sure how to reach the blackberry's/androids/nokia's without effect the code of my actual site. I'm building my site using the PHP framework CodeIgniter and I looked into this code which is suppose to be able to tell if it is being looked at through a mobile device or browser. if ($this->agent->is_browser()) { $agent = $this->agent->browser().' '.$this->agent->version(); } elseif ($this->agent->is_mobile()) { $agent = $this->agent->mobile(); } else { $agent = 'Unidentified User Agent'; } The only problem is that the newer phones we are building on render the site as a browser and not as a mobile (I think, I've only tested the iphone because it's all I have at the moment). So does anyone have any work arounds for the other phone platforms?

  • CoreData : store images to DB or not?

    - by Meko
    Hi.I am making an app that it takes photos from web site for some Username and shows it on UITable with username then when clicking user name it shows photos for this user and then clicking to name of photo it shows full screen photo. My question is I am using NSData to get photos from internet.Am I have to save also those data to CoreDAta? I am using like when pressing name of user it again creates NSData and downloads photos from internet and shows them on UTable. And it takes time. What is good approach? and How can save this images to CoreDAta? I am using this method NSData *imageData=[flickr dataForPhotoID:firstPhoto.id fromFarm:firstPhoto.farm onServer:firstPhoto.server withSecret:firstPhoto.secret inFormat: FlickrFetcherPhotoFormatSquare]; and here definition of dataForPtohoID method - (NSData *)dataForPhotoID:(NSString *)photoID fromFarm:(NSString *)farm onServer:(NSString *)server withSecret:(NSString *)secret inFormat:(FlickrFetcherPhotoFormat)format { #if TEST_HIGH_NETWORK_LATENCY sleep(1); #endif NSString *formatString; switch (format) { case FlickrFetcherPhotoFormatSquare: formatString = @"s"; break; case FlickrFetcherPhotoFormatLarge: formatString = @"b"; break; } NSString *photoURLString = [NSString stringWithFormat:@"http://farm%@.static.flickr.com/%@/%@_%@_%@.jpg", farm, server, photoID, secret, formatString]; NSURL *url = [NSURL URLWithString:photoURLString]; return [NSData dataWithContentsOfURL:url]; }

  • How close can I get C# to the performance of C++ for small intensive tasks?

    - by SLC
    I was thinking about the speed difference of C++ to C# being mostly about C# compiling to byte-code that is taken in by the JIT compiler (is that correct?) and all the checks C# does. I notice that it is possible to turn a lot of these functions off, both in the compile options, and possibly through using the unsafe keyword as unsafe code is not verifiable by the common language runtime. Therefore if you were to write a simple console application in both languages, that flipped an imaginary coin an infinite number of times and displayed the results to the screen every 10,000 or so iterations, how much speed difference would there be? I chose this because it's a very simple program. I'd like to test this but I don't know C++ or have the tools to compile it. This is my C# version though: static void Main(string[] args) { unsafe { Random rnd = new Random(); int heads = 0, tails = 0; while (true) { if (rnd.NextDouble() > 0.5) heads++; else tails++; if ((heads + tails) % 1000000 == 0) Console.WriteLine("Heads: {0} Tails: {1}", heads, tails); } } } Is the difference enough to warrant deliberately compiling sections of code "unsafe" or into DLLs that do not have some of the compile options like overflow checking enabled? Or does it go the other way, where it would be beneficial to compile sections in C++? I'm sure interop speed comes into play too then. To avoid subjectivity, I reiterate the specific parts of this question as: Does C# have a performance boost from using unsafe code? Do the compile options such as disabling overflow checking boost performance, and do they affect unsafe code? Would the program above be faster in C++ or negligably different? Is it worth compiling long intensive number-crunching tasks in a language such as C++ or using /unsafe for a bonus? Less subjectively, could I complete an intensive operation faster by doing this?

  • Django FormWizard with dynamic forms

    - by krys
    I want to implement a simple 2 part FormWizard. Form 1 will by dynamically generated something like this: class BuyAppleForm(forms.Form): creditcard = forms.ChoiceField(widget = forms.RadioSelect) type = forms.ChoiceField(widget = forms.RadioSelect) def __init__(self,*args, **kwargs): user = kwargs['user'] del kwargs['user'] super(BuyAppleForm, self).__init__(*args, **kwargs) credit_cards = get_credit_cards(user) self.fields['creditcard'].choices = [(card.id,str(card)) for card in credit_cards] apple_types= get_types_packages() self.fields['type'].choices = [(type.id,str(type)) for type in apple_types] This will dynamically create a form with lists of available choices. My second form, I actually want no input. I just want to display a confirmation screen containing the credit card info, apple info, and money amounts (total, tax, shipping). Once user clicks OK, I want the apple purchase to commence. I was able to implement the single form way by passing in the request.user object in the kwargs. However, with the FormWizard, I cannot figure this out. Am I approaching the problem wrong and is the FormWizard not the proper way to do this? If it is, how can the Form __init__ method access the user object from the HTTP request?

  • Shape object in Processing, translate individual shapes.

    - by Zain
    I am relatively new to Processing but have been working in Java for about 2 years now. I am facing difficulty though with the translate() function for objects as well as objects in general in processing. I went through the examples and tried to replicate the manners by which they instantiated the objects but cannot seem to even get the shapes to appear on the screen no less move them. I instantiate the objects into an array using a nested for loop and expect a grid of the objects to be rendered. However, nothing at all is rendered. My nested for loop structure to instantiate the tiles: for(int i=0; i<102; i++){ for(int j=0; j<102; j++){ tiles[i][j]=new tile(i,0,j); tiles[i][j].display(); } } And the constructors for the tile class: tile(int x, int y, int z){ this.x=x; this.y=y; this.z=z; beginShape(); vertex(x,y,z); vertex(x+1,y,z); vertex(x+1,y,z-1); vertex(x,y,z-1); endShape(); } Nothing is rendered at all when this runs. Furthermore, if this is of any concern, my translations(movements) are done in a method I wrote for the tile class called move which simply calls translate. Is this the correct way? How should one approach this? I can't seem to understand at all how to render/create/translate individual objects/shapes. Thanks for any help any of you are able to provide!

  • how do i work bool!

    - by user350217
    HI! im a beginner and im really getting frustrated with this whole concept. i dont understand how to exactly use the bool function. i know what it is but i cantfigure out how to make it work in my program. Im trying to say that if my variable "selection" is any letter beween 'A' and 'I' then it is valid and can continue on to the next function which is called calcExchangeAmt(amtExchanged, selection). if it is false i want it to ask the user if they want to repeat the program and if they agree to repeat i want it to clear the screen and restart to the main function. please help edit my work! this is my bool function: bool isSelectionValid(char selection, char yesNo, double amtExchanged) { bool validData; validData = true; if((selection >= 'a' && selection <= 'i') || (selection >= 'A' && selection <= 'I')) { validData = calcExchangeAmt (amtExchanged, selection); } else(validData == false); { cout<<"Do you wish to continue? (Y for Yes / N for No)"; cin>>yesNo; } do { main(); } while ((yesNo =='y')||(yesNo == 'Y')); { system("cls"); } return 0; } this is the warning that im gettng: warning C4800: 'double' : forcing value to bool 'true' or 'false' (performance warning)

  • UIViewController remaining

    - by Guy
    Hi Guys. I have a UIViewController named equationVC who's user interface is being programmatically created from another NSObject class called equationCon. Upon loading equationVC, a method called chooseInterface is called from the equationCon class. I have a global variable (globalVar) that points to a user defined string. chooseInterface finds a method in the equationCon class that matches the string globalVar points to. In this case, let's say that globalVar points to a string that is called "methodThatMatches." In methodThatMatches, another view controller needs to show the results of what methodThatMatches did. methodThatMatches creates a new equationVC that calls upon methodThatMatches2. As a test, each method changes the color of the background. When the application starts up, I get a purple background, but as soon as I hit backwards I get another purple screen, which should be yellow. I do not think that I am release the view properly. Can anyone help? -(void)chooseInterface { NSString* equationTemp = [globalVar stringByReplacingOccurrencesOfString:@" " withString:@""]; equationTemp = [equationTemp stringByReplacingOccurrencesOfString:@"'" withString:@""]; SEL equationName = NSSelectorFromString(equationTemp); NSLog(@"selector! %@",NSStringFromSelector(equationName)); if([self respondsToSelector:equationName]){ [self performSelector:equationName]; } } -(void)methodThatMatches{ self.equationVC.view.backgroundColor = [UIColor yellowColor]; [setGlobalVar:@"methodThatMatches2"]; EquationVC* temp = [[EquationVC alloc] init]; [[self.equationVC navigationController] pushViewController:temp animated:YES ]; [temp release]; } -(void)methodThatmatches2{ self.equationVC.view.backgroundColor = [UIColor purpleColor]; }
