• Using std::ifstream to load in an array of struct data type into a std::vector

  - by Sent1nel

  I am working on a bitmap loader in C++ and when moving from the C style array to the std::vector I have run into an usual problem of which Google does not seem to have the answer. 8 Bit and 4 bit, bitmaps contain a colour palette. The colour palette has blue, green, red and reserved components each 1 byte in size. // Colour palette struct BGRQuad { UInt8 blue; UInt8 green; UInt8 red; UInt8 reserved; }; The problem I am having is when I create a vector of the BGRQuad structure I can no longer use the ifstream read function to load data from the file directly into the BGRQuad vector. // This code throws an assert failure! std::vecotr quads; if (coloursUsed) // colour table available { // read in the colours quads.reserve(coloursUsed); inFile.read( reinterpret_cast(&quads[0]), coloursUsed * sizeof(BGRQuad) ); } Does anyone know how to read directly into the vector without having to create a C array and copy data into the BGRQuad vector?

• setting write permissions on theme subdirectory?

  - by Scott B

  I've a theme which supports multiple templates, each with a header background image whose color can be set by the site owner via a colorpicker widget in my theme's options panel. This has the effect of opening the background image, recoloring it and resaving it back to the server. I've had zero issues with this routine until recently when a customer installed the theme on a web host whose default read/write permissions are apparently much more restrictive than the norm. In this case, the user was unable to alter the colors of the template images because of the permissions settings. I'm looking for a bit of understanding on what the permissions would need to be (assuming I purposefully set them via script) to allow the logged in wordpress user to write to files under my theme's styles directory. The code I'm using to write to the image file is below... $img = imagecreatefromgif("../wp-content/themes/mytheme/styles/".get_option('my_theme')."/image.gif"); $color = imagecolorallocate($img, $info["red"], $info["green"], $info["blue"]); imagecolorset($img, 0, $info["red"], $info["green"], $info["blue"]); imagegif($img, $path);

• How to sum up a fetched result's number property based on the object's category?

  - by mr_kurrupt

  I have a NSFetchRequest that is returning all my saved objects (call them Items) and storing them in an NSMutableArray. Each of these Items have a category, an amount, and some other properties. My goal is to check the category of each Item and store the sum of the amounts for objects of the same category. So if I had these Items: Red; 10.00 Blue; 20.00 Green; 5.00 Red; 5.00 Green; 15.00 then I would have an array or other type of container than has: Red; 15.00 Blue; 20.00 Green; 20.00 What would be the best way to organize the data in such a manner? I was going to create a object class (call it Totals) that just has the category and amount. As I traverse through the fetch results in a for-loop, add Items with the same category in a Totals object an store them in a NSMutableArray. The problem I ran into with that is that I'm not sure how to check if an array contains a Totals object with a specific property. Specifically, a category that already exists. So if 'Red' exists, add the amount to it, otherwise create a new Totals object with category 'Red' and a the first Item's amount. Thanks.

• I have a fucntion that create histogram of each Bitmap. How can i create another 3 histograms for R.G.B of each Bitmap?

  - by Daniel Lip

  This is the histogram function im using today and if im not worng it's creating an histogram by Gray color. What i want is another fucntion that will return me 3 histograms of each Bitmap: The first histogram will be of the Red color of the bitmap the second for the Green color and the last one for the Blue color. public static long[] GetHistogram(Bitmap b) { long[] myHistogram = new long[256]; BitmapData bmData = null; try { //Lock it fixed with 32bpp bmData = b.LockBits(new Rectangle(0, 0, b.Width, b.Height), ImageLockMode.ReadOnly, PixelFormat.Format32bppArgb); int scanline = bmData.Stride; System.IntPtr Scan0 = bmData.Scan0; unsafe { byte* p = (byte*)(void*)Scan0; int nWidth = b.Width; int nHeight = b.Height; for (int y = 0; y < nHeight; y++) { for (int x = 0; x < nWidth; x++) { long Temp = 0; Temp += p[0]; // p[0] - blue, p[1] - green , p[2]-red Temp += p[1]; Temp += p[2]; Temp = (int)Temp / 3; myHistogram[Temp]++; //we do not need to use any offset, we always can increment by pixelsize when //locking in 32bppArgb - mode p += 4; } } } b.UnlockBits(bmData); } catch { try { b.UnlockBits(bmData); } catch { } } return myHistogram; } How may i do it ?

• Create Clone Without Effecting Results of Original Object

  - by user1655096

  I have a function that when selecting an option, returns results. I want to be able to clone that function and have the ability to return another set of results, without adding the new results to the original object. // shows / hides results based on selection $(".categories-select").live("change" ,function(){ if($(this).val() == 'red'){ $('.red').removeClass('hide'); // toggles red results, sub menus $(this).parent('.controls').find('.sub').removeClass('hide'); } if($(this).val() == 'blue'){ $('.blue').removeClass('hide'); $(this).parent('.controls').find('.sub').addClass('hide'); } if($(this).val() == 'purple'){ $('.purple').removeClass('hide'); $(this).parent('.controls').find('.sub').addClass('hide'); } if($(this).val() == 'orange'){ $('.orange').removeClass('hide'); $(this).parent('.controls').find('.sub').addClass('hide'); } }); // Duplicates category select menu $(".add-color").find(function(){ $(".color-category").clone().removeClass('color-category').appendTo("#we-want-to").find('.sub,').addClass('hide') ; }); $(".add-color-alternate").click(function(){ $(".color-category-alternate").clone().removeClass('color-category-alternate').appendTo("#we-want-to").find('.sub, .results-table').addClass('hide'); });

• Array, change color, as3

  - by pixelGreaser

  Hi Thanks for the help Yesterday, but I have on more question. How can I change color of text on certain words? My animation plays the text animation of THIS SALE IS RED HOT!!! I want RED HOT it to be red. It seems the array can be indexed in such a way to switch the color from Blue to Red. MY BANNER ADD var myArray:Array = ["THIS","SALE","IS","RED HOT!!!",]; var tm:Timer = new Timer(500); tm.addEventListener(TimerEvent.TIMER, countdown); function countdown(event:TimerEvent) { tx.text = myArray[(tm.currentCount-1)%myArray.length]; } tm.start(); tx.textColor = 0x0000FF; Cont...PSEUDO CODE //var myArray:Array = ["This","Sale","is","RED HOT!!!",]; var spliceRedhot = myArray.splice(-1); //trace(myArray[2]); trace(spliceRedhot); function mySplice(e:Event):void{ if (spliceRedhot = 4){ //Make RED HOT!!! red tx.textColor = 0xFF0000; } else{ //Text is Blue again tx.textColor = 0x0000FF; } }

• Why the compiler is not compiling a line in C++ Builder?

  - by MLB

  Hi boys: I was programming an application in C++ Builder 6, and I had encountered this rare problem: void RotateDice() { Graphics::TBitmap *MYbitmap = new Graphics::TBitmap(); Randomize(); int rn = random(6) + 1; switch (rn) { case 1: { //... break; } //... Some cases... } ShowDice(); //it's a function to show the dice delete MYbitmap; //the compiler don't get it!!!! } In the line "ShowDice()", the compiler jumps to the final of the RotateDice() method, it doesn't "see" the line "delete MYbitmap". When I compile the program, every compiled line shows a little blue point in its left side, but that line don't show the blue point... it's like the compiler don't "see" the line of code. What's happening with that???? Note: Some days ago, I was writing a program in Delphi and I was advice of that problematic issue. Some like that happened to me in Delphi 7... So, waht the problem with that? I am so sorry about my English. I am from Cuba.

• Adding a ActionPerformed Array to a String Array

  - by user267490

  Hey, Before you guys ask, yes I've searched online for the answer, but everything I found just leaves a lil confuse and nothing is recent so asking in those forums won't really help. My problems is this: I have an array that holds my name for a menu. String[] fontColor = new String[] {"Red", "Blue", "Green"}; for (int i = 0; i < fontColors.length; i++) { JMenuItem fontC = new JMenuItem(fontColors[i]); fontC.addActionListener(new fontColorAction()); changeFontColor.add(fontC); } Then I have an array that holds my color change in a class called fontColorAction in that class I have another array that does the same thing as my string array except all thats in the statement is textarea.setForeground(colorArr[i]); that will set the setForeground() in order, but now how do I successfully attact the action listner in my class to my menuItems? my class looks like this private class fontColorAction implements ActionListener { Color[] colorArr - new Color[] {"Color.RED","Color.BLUE","Color.GREEN"}; public void actionPerformed(ActionEvent e){ for(i = 0; i < collorArr.length; i++){ textarea.setForeground(colorArr[i]); } } }

• Handling multiple media queries in Sass with Twitter Bootstrap

  - by Keith

  I have a Sass mixin for my media queries based on Twitter Bootstrap's responsive media queries: @mixin respond-to($media) { @if $media == handhelds { /* Landscape phones and down */ @media (max-width: 480px) { @content; } } @else if $media == small { /* Landscape phone to portrait tablet */ @media (max-width: 767px) {@content; } } @else if $media == medium { /* Portrait tablet to landscape and desktop */ @media (min-width: 768px) and (max-width: 979px) { @content; } } @else if $media == large { /* Large desktop */ @media (min-width: 1200px) { @content; } } @else { @media only screen and (max-width: #{$media}px) { @content; } } } And I call them throughout my SCSS file like so: .link { color:blue; @include respond-to(medium) { color: red; } } However, sometimes I want to style multiple queries with the same styles. Right now I'm doing them like this: .link { color:blue; /* this is fine for handheld and small sizes*/ /*now I want to change the styles that are cascading to medium and large*/ @include respond-to(medium) { color: red; } @include respond-to(large) { color: red; } } but I'm repeating code so I'm wondering if there is a more concise way to write it so I can target multiple queries. Something like this so I don't need to repeat my code (I know this doesn't work): @include respond-to(medium, large) { color: red; } Any suggestions on the best way to handle this?

• 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

• (Android) Why won't invalidate() update my buttons immediately?

  - by frustrated user

  I have read several forums and examples on using invalidate() in order to update views immediately but I still do not understand why what I am doing will not work. The code below uses image buttons defined by "red", "blue", "green", and "yellow". I set a 1 second delay between each time I try and change a button's appearance. Please someone tell me what i'm doing wrong. private void showPattern() { if (correct == true) { for (int k = 0; k < temp_basket.length; k++) { if (temp_basket[k] == 0) { red.setPressed(true); red.invalidate(); final Handler handler = new Handler(); Timer t = new Timer(); t.schedule(new TimerTask() { public void run() { handler.post(new Runnable() { public void run() { red.setPressed(false); red.invalidate(); } }); } }, 1000); There are 3 more or these blocks after this one that are blue, green, and yellow.

• Polling a web URL until event

  - by Jaxo

  I'm really sorry about the crappy title - if anybody has a better way of wording it, please edit it! I basically need to have a C# application run a function if the output of a URL is a certain value. For example, if the website says blue the background colour will be blue, red to make it red, etc. The problem is I don't want to spam my webserver with checks. The 4 bytes it downloads each time is negligible, but if I were to deploy this type of system on multiple computers, it would get slower and slower and the bandwidth would add up quickly. So my question is: How can my desktop application run a piece of code only when a web URL has a different output without checking each time? I can't use sockets, and any sort of LAN protocol won't end up working. My reasoning behind this potentially nefarious code is to be able to mute computers by updating a file on the website (as you may have seen in my previous question today, sorry!). I'd like it to be rather quick, and not have the refresh time minutes apart, a few seconds at the most would be ideal. How can I accomplish this? The website's code is easy, but getting the C# application to check when it changes is the part I'm stuck on. Nothing shows up on the website other than the command. Thanks!

• JavaScript: supposed to execute functions sequentially, not actually doing so?

  - by AP257

  I'm seeing a lot of answers on StackOverflow that say that JavaScript executes code sequentially, but I can actually see my own JavaScript not doing so. From the following code: function centre_map(lat, lng, zoom_level) { alert('centre_map'); map = new GMap2(document.getElementById('map_canvas')); var latlng = new GLatLng(lat, lng); map.setCenter(latlng, zoom_level); } function add_markers_within_bounds() { alert('add_markers_within_bounds'); // add numerous BLUE markers within map bounds using MarkerClusterer } function add_marker(lat, lng, place_name, grid, county) { alert('add_marker'); // add one ordinary RED Google Maps marker } centre_map('{{lat}}', '{{lng}}', 12); add_markers_within_bounds('{{grid}}', '{{place_name}}'); add_marker('{{lat}}', '{{lng}}', '{{place_name}}', '{{grid}}', '{{county}}'); I get the following sequence of events: 'centre_map' alert 'add_markers_within_bounds' alert 'add_marker' alert individual RED marker appears on map (i.e. add_marker renders) multiple BLUE markers appear on map (i.e. add_markers_within_bounds renders) Why doesn't add_markers_within_bounds complete before add_marker gets under way: and how can I make it do so? I know that one way might be to call add_marker from within add_markers_within_bounds, but for various reasons I'd rather keep it as a separate function.

• Usability for notification messages, colors

  - by metrobalderas

  In each app I develop, I like to add three types of messages: Green/blue for success messages Yellow for warnings Red for errors And perhaps, a neutral one for information, which is gray or blue if the success one is green. The success one is used for when an item is created or updated, the yellow one is when there's something wrong, but not we-are-going-to-die wrong and the red one is when something is blocked or we are going to die. However, there's one thing I can't figure out, when I delete an object, what kind of notification should I use? I think the success one is not because it is not expected, altough the deletion was successful, the user tends not to read the message, just to see the color. The red one might be, but it can be misunderstood (I tried to delete it but there was an error), the warning and the information one might be good choices, but I'm not really sure. Also, when you ask for confirmation about deleting something, the 'cancel' button should be green or red? I'm just curious how you guys handle this. Thanks.

• Using Color.rgb() doesnt work for full 0...255 range

  - by superflyninja

  I'm writing an android game using opengl. I'm using: colour = Color.rgb(theR,theG,theB); (all ints) to store the color of a rectangle. Then I parse out the RGB to render the rectangle: colorR = Color.red(color); colorG = Color.green(color); colorB = Color.blue(color); For example for color 53,130,255 this should result in a blue but on my app it results in a white. If i use 1,1,1 i get white. If i use 0,0,0 i get black. If i use 0,1,0 I get green etc. So it looks like any value over one is treated as 1 and so i am not getting the full 0...255 range. I tried using Color.argb and color = Color.parseColor(theColor) where the Color is a string. I'm using this in an opengles app. I have a class to display a rectangle of color. This definitely works fine as the correct size rectangle is rendered, just not a color using values above 1. I also use textures and everything displays fine. any ideas? thanks a million

• MySQL won't stop doing stuff

  - by Felix

  Sorry for the title of the question, here's my problem: I've been trying to set up some scripts that import a lot of stuff hourly from an external source. They seemed to work fine, so I set up a cronjob to run them every hour. One day later I find six or seven instances of that script just hogging the MySQL server, making it unresponsive. I killed their processes, but MySQL was still not responding. I had to kill MySQL, reboot and then MySQL started working again (who knows on what) and being unresponsive (yes, I did remove the scripts from the cronjobs). I SHOW PROCESSLISTed and killed every process I could find. Still nothing, MySQL is hogging the HDD and is at the top of top and making the server load go up in the sky. I don't know what to do, if I kill and start it again it will probably do the same thing. What should I do?

• OS X software updates download but don't install

  - by ridogi

  I've got three 10.6 computers that won't install OS X updates. Checking for new software will show about a dozen updates (Security updates, Safari, iPhoto, printers, etc) and if choose install it downloads them. After downloading and then clicking restart the computer sits at the purplish sky desktop with no progress bar, and then after about 3 minutes it goes back to the login window (without ever installing or restarting). If I then select check for updates the same updates will all be presented and I can repeat the process. Manually downloading and installing an update such as 10.6.8 combo updater works as it should, and then check for updates no longer presents that particular update as an option. This seems to be the result of some setting or 3rd party application as I've got 3 out 7 computers experiencing this exact same problem. What could cause this and how can I fix it?

• Controlling TV Channel Through Computer

  - by killianmcc

  I'm passing my TV input through my computer so that I can use the video stream in an application I'm creating which then outputs to my TV. E.g. Sky Digibox/FreeView box - Laptop - TV Where on my laptop I'll be using the stream in a WPF application so I can overlay XAML objects onto it. My question is, what would be the best way for me to send the signal back to the box to say change the channel for example? I don't want to have to use the remote, I want the computer to handle everything. Is there a standard cable these boxes have that could take what would normally be a remote control signal and use that as input instead? Or would I have to go down the route of looking at some sort of Infared LED to send the signal recreating the remote? Apologies if this is not clear enough, let me know and I'll try and be more precise.

• Why is RAM usage so high on an idle server? [duplicate]

  - by DeeDee

  This question already has an answer here: Why is Linux reporting “free” memory strangely? 2 answers I'm investigating a server used for scientific data analysis. It's running RHEL 6.4 It has almost 200GB of RAM. It's been running very slowly for users via SSH, and after some poking around I quickly noticed that the RAM usage was sky-high. What's odd is that even in an idle state it's still using a ton of RAM: I also looked via htop and I can't see that any running process is using more than 0.1% of the RAM. So I wonder what's going on? Right now the only user-initiated process running is an rsync between two NFS-mounted shares. I tried rebooting the server and it was much more responsive for a few minutes, but then memory usage shot up again. Is there any way I can pinpoint why memory usage is so high?

With his shader class, he intialise it thusly: void SHADER::Init(IDirect3DDevice9 *Dev, const char fName[], int typ) { m_pDevice = Dev; m_type = typ; if(m_pDevice == NULL)return; // Assemble and set the pixel or vertex shader HRESULT hRes; LPD3DXBUFFER Code = NULL; LPD3DXBUFFER ErrorMsgs = NULL; if(m_type == PIXEL_SHADER) hRes = D3DXCompileShaderFromFile(fName, NULL, NULL, "Main", "ps_2_0", D3DXSHADER_DEBUG, &Code, &ErrorMsgs, &m_pConstantTable); else hRes = D3DXCompileShaderFromFile(fName, NULL, NULL, "Main", "vs_2_0", D3DXSHADER_DEBUG, &Code, &ErrorMsgs, &m_pConstantTable); } How ever, this generates the following error: Error 1 error C2664: 'D3DXCompileShaderFromFileW' : cannot convert parameter 1 from 'const char []' to 'LPCWSTR' The compiler states the issue is with fName in the D3DXCompileShaderFromFile line. I know this has something to do with the character set, and my program was already running with a Unicode Character set on the go. I read that to solve the above problem, I need to switch to a multi-byte character set. But, if I do that, I get other errors in my code, like so: Error 2 error C2664: 'D3DXCreateEffectFromFileA' : cannot convert parameter 2 from 'const wchar_t *' to 'LPCSTR' With it being accredited to the following line of code: if(FAILED(D3DXCreateEffectFromFile(m_pD3DDevice9,effectFileName.c_str(),NULL,NULL,0,NULL,&m_pCurrentEffect,&pErrorBuffer))) This if is nested within another if statement checking my effectmap list. Though it is the FAILED word with the red line. Like wise I get the another error with the following line of code: wstring effectFileName = TEXT("Sky.fx"); With the error message being: Error 1 error C2440: 'initializing' : cannot convert from 'const char [7]' to 'std::basic_string<_Elem,_Traits,_Ax' If I change it back to a Uni code character set, I get the original (fewer) errors. Leaving as a multi-byte, I get more errors. Does anyone know of a way I can fix this issue?
