  • Microsoft C++ Language Reference

    - by eSKay
    Whenever any question is asked, and a reference text is needed, I never see MSDN C++ Language Reference being referred. I was browsing through it and I personally feel that it is extremely well written. Is there some specific reason it is not used as often as a standard? Is it because it contains some VC++ specific features?

  • How do I make a full screen scrolling messagebox or window?

    - by chobo2
    Hi First let me start of saying I know absolutely nothing about c++ and I am really just more interested in getting this to work then learning c++(I got enough on my plate to learn). So basically I am trying to make a terms of service for my windows mobile 6 professional application but it seems I need to use c++ to do it. After hours of searching I found a solution but it developed for windows mobile standard. So they somehow used c++ to make a message box and on standard devices(ie non touch screen phones) the message box can have like scrolling. For some reason this is not the case with professional devices(touch screen devices). So my message box goes off the page and you can never accept or decline the terms. So your stuck and on the screen forever till you do some sort of soft restart. http://www.mobilepractices.com/2008/10/setupdll-sample-and-walkthrough-terms.html The above link is the tutorial but here is the actual file that seems to display the message. #include "stdafx.h" #include "ce_setup.h" // This is a variable containing the text to be displayed // in the Terms & Conditions dialog TCHAR Message[] = _T("TERMS & CONDITIONS\r\n ") _T("Selecting YES you're accepting our terms & conditions.\r\n") _T("This is just a sample application.\r\n") _T("From http://www.mobilepractices.com\r\n") _T("You can replace this text with your own.\r\n") _T("We're using a setup.dll to show this dialog.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Last line.\r\n") ; // This function will be called when the user // tries to install the cab. According to its return // value the installation continues or is cancelled. // As this could be called more than once // (i.e. if there is not enough space on the target) // we should take care about fFirstCall parameter // to show the dialog only once. codeINSTALL_INIT Install_Init( HWND hwndParent, BOOL fFirstCall, BOOL fPreviouslyInstalled, LPCTSTR pszInstallDir ) { if (!fFirstCall || ::MessageBoxW(0, Message, _T("SplashScreenSample") , MB_YESNO) == IDYES) return codeINSTALL_INIT_CONTINUE; else return codeINSTALL_INIT_CANCEL; } So I want to change this to something that can scroll. Can I use like a panel control since I know what has scroll or something else? Thanks

  • Checkbox alignment in Internet Explorer, Firefox and Chrome

    - by Andrej
    Checkbox alignment with its label (i.e., vertical centering) cross different web browsers makes me crazy. Pasted below is standard html code: <label for="ch"><input id="ch" type="checkbox">My Checkbox</label> I tested different CSS tricks (e.g., link 1, link 2); most solutions works fine in FF, but are completely off in Chrome or IE8. I'm looking for any references or pointers to solve this issue. Thanks in advance. EDIT According to Elq suggestion I modified the HTML <div class="row"> <input type="checkbox" id="ch1" /> <label for="ch1">Test</label> </div> and CSS .row{ display: table-row; } label{ display: table-cell; vertical-align: middle; } Works now in Firefox, Internet Explorer 8, and Chrome on Windows. Fails on Firefox and Chrome on Linux. Also works in Firefox and Safari on Mac, but fails on Chrome.

  • Encrypt string with public key only

    - by vlahovic
    i'm currently working on a android project where i need to encrypt a string using 128 bit AES, padding PKCS7 and CBC. I don't want to use any salt for this. I've tried loads of different variations including PBEKey but i can't come up with working code. This is what i currently have: String plainText = "24124124123"; String pwd = "BobsPublicPassword"; byte[] key = pwd.getBytes(); key = cutArray(key, 16); byte[] input = plainText.getBytes(); byte[] output = null; SecretKeySpec keySpec = null; keySpec = new SecretKeySpec(key, "AES"); Cipher cipher = Cipher.getInstance("AES/CBC/PKCS7Padding"); cipher.init(Cipher.ENCRYPT_MODE, keySpec); output = cipher.doFinal(input); private static byte[] cutArray(byte[] arr, int length){ byte[] resultArr = new byte[length]; for(int i = 0; i < length; i++ ){ resultArr[i] = arr[i]; } return resultArr; } Any help appreciated //Vlahovic

  • Graphviz for documentation.

    - by Marcin
    I noticed that doxygen uses the graphviz library for creating diagrams. Have you ever used graphviz for generating documentation? Is it worth learning the graphviz for documentation purposes outside the scope of doxygen? Or am I better off to sticking with a standard data modeling package like Visio? I understand the merits of it as a graphing library, but for trying to represent more complex UML (or similar) is it still worth looking into?

  • doubt in javascript name validation

    - by raja
    Hi: I am using the below validation for textbox which accepts only alphabets and maximum of 50 characters. I am passing the object directly in the parameter. The below case by giving the field name i.e "my_text" directly is working is working fine. But if i pass it in variable, that time it is not working(commented the if statement). Please help me. My requirement is each time when we enter the charater, the hardcode field name should not be used in the validation. <html><head> <script language=JavaScript> function check_length(my_form,fieldName) { alert(fieldName); // if (my_form.fieldName.value.length >= maxLen) { if (my_form.my_text.value.length >= maxLen) { var msg = "You have reached your maximum limit of characters allowed"; alert(msg); my_form.my_text.value = my_form.my_text.value.substring(0, maxLen); } else{ var keyCode = window.event.keyCode; if ((keyCode < 65 || keyCode > 90) && (keyCode < 97 || keyCode > 123) && keyCode != 32) { window.event.returnValue = false; alert("Enter only Alphabets"); } my_form.text_num.value = maxLen - my_form.my_text.value.length;} } </script> </head> <body> <form name=my_form method=post> <input type="text" onKeyPress=check_length(this.form,this.name); name=my_text rows=4 cols=30> <br> <input size=1 value=50 name=text_num> Characters Left </form> </body> </html>

    Hi all ! What should be the buffer offset value for U & V in YUV444 format type? Like for an example if i am using YV12 format the value is as follows: ppData.inputIDMAChannel.UBufOffset = iInputHeight * iInputWidth + (iInputHeight * iInputWidth)/4; ppData.inputIDMAChannel.VBufOffset = iInputHeight * iInputWidth; iInputHeight = 160 & iInputWidth = 112 ppdata is an object for the following structure: typedef struct ppConfigDataStruct { //--------------------------------------------------------------- // General controls //--------------------------------------------------------------- UINT8 IntType; // FIRSTMODULE_INTERRUPT: the interrupt will be // rised once the first sub-module finished its job. // FRAME_INTERRUPT: the interrput will be rised // after all sub-modules finished their jobs. //--------------------------------------------------------------- // Format controls //--------------------------------------------------------------- // For input idmaChannel inputIDMAChannel; BOOL bCombineEnable; idmaChannel inputcombIDMAChannel; UINT8 inputcombAlpha; UINT32 inputcombColorkey; icAlphaType alphaType; // For output idmaChannel outputIDMAChannel; CSCEQUATION CSCEquation; // Selects R2Y or Y2R CSC Equation icCSCCoeffs CSCCoeffs; // Selects R2Y or Y2R CSC Equation icFlipRot FlipRot; // Flip/Rotate controls for VF BOOL allowNopPP; // flag to indicate we need a NOP PP processing }*pPpConfigData, ppConfigData; and idmaChannel structure is as follows: typedef struct idmaChannelStruct { icFormat FrameFormat; // YUV or RGB icFrameSize FrameSize; // frame size UINT32 LineStride;// stride in bytes icPixelFormat PixelFormat;// Input frame RGB format, set NULL // to use standard settings. icDataWidth DataWidth;// Bits per pixel for RGB format UINT32 UBufOffset;// offset of U buffer from Y buffer start address // ignored if non-planar image format UINT32 VBufOffset;// offset of U buffer from Y buffer start address // ignored if non-planar image format } idmaChannel, *pIdmaChannel; I want the formulae for ppData.inputIDMAChannel.UBufOffset & ppData.inputIDMAChannel.VBufOffset for YUV444 Thanks in advance

  • gcc - using -werror and -std= -pedantic considered good practice?

    - by Helper Method
    I'm just digging into the gcc manual and some things are still unclear to me: a) When specifying a std, should I always use -pedantic in conjunction? b) When using -g, it the standard level sufficient or should I specify level 3, i.e. -g3? c) Is it good practice to use -Werror to promote all warnings to errors and -pedantic-errors to promote all pedantic warnings to errors?

  • OpenGL Shader Compile Error

    - by Tomas Cokis
    I'm having a bit of a problem with my code for compiling shaders, namely they both register as failed compiles and no log is received. This is the shader compiling code: /* Make the shader */ Uint size; GLchar* file; loadFileRaw(filePath, file, &size); const char * pFile = file; const GLint pSize = size; newCashe.shader = glCreateShader(shaderType); glShaderSource(newCashe.shader, 1, &pFile, &pSize); glCompileShader(newCashe.shader); GLint shaderCompiled; glGetShaderiv(newCashe.shader, GL_COMPILE_STATUS, &shaderCompiled); if(shaderCompiled == GL_FALSE) { ReportFiler->makeReport("ShaderCasher.cpp", "loadShader()", "Shader did not compile", "The shader " + filePath + " failed to compile, reporting the error - " + OpenGLServices::getShaderLog(newCashe.shader)); } And these are the support functions: bool loadFileRaw(string fileName, char* data, Uint* size) { if (fileName != "") { FILE *file = fopen(fileName.c_str(), "rt"); if (file != NULL) { fseek(file, 0, SEEK_END); *size = ftell(file); rewind(file); if (*size > 0) { data = (char*)malloc(sizeof(char) * (*size + 1)); *size = fread(data, sizeof(char), *size, file); data[*size] = '\0'; } fclose(file); } } return data; } string OpenGLServices::getShaderLog(GLuint obj) { int infologLength = 0; int charsWritten = 0; char *infoLog; glGetShaderiv(obj, GL_INFO_LOG_LENGTH,&infologLength); if (infologLength > 0) { infoLog = (char *)malloc(infologLength); glGetShaderInfoLog(obj, infologLength, &charsWritten, infoLog); string log = infoLog; free(infoLog); return log; } return "<Blank Log>"; } and the shaders I'm loading: void main(void) { gl_FragColor = vec4(1.0, 0.0, 0.0, 1.0); } void main(void) { gl_Position = ftransform(); } In short I get From: ShaderCasher.cpp, In: loadShader(), Subject: Shader did not compile Message: The shader Data/Shaders/Standard/standard.vs failed to compile, reporting the error - <Blank Log> for every shader I compile I've tried replacing the file reading with just a hard coded string but I get the same error so there must be something wrong with how I'm compiling them. I have run and compiled example programs with shaders, so I doubt my drivers are the issue, but in any case I'm on a Nvidia 8600m GT. Can anyone help?

  • How do I get a less than in a javascript for loop in XSL to work?

    - by Kyle
    I am using CDATA to escape the script but in IE8's debugger I still get this message: "Expected ')'" in the for loop conditions. I am assuming it still thinks that the ; in the &lt; generated by CDATA is ending the loop conditions. Original script in my XSL template: <script type="text/javascript" language="javascript"> <![CDATA[ function submitform(form){ var oErrorArray = new Array(); for (i=0;i<form.length;i++) eval("oErrorArray["+i+"]=oError"+i); var goForm = true; for(i=0;i<form.length;i++) { oErrorArray[i].innerHTML = ""; if(form[i].value="")){ oErrorArray[i].innerHTML = "Error - input field is blank"; goForm = false; } } if(goForm == true) form.submit(); } function resetform(form){ form.reset(); } ]]> </script> Code generated after transformation (from IE8 debugger): <script type="text/javascript" language="javascript"> function submitform(form){ var oErrorArray = new Array(); for (i=0;i&lt;form.length;i++) eval("oErrorArray["+i+"]=oError"+i); goForm = true; for(i=0;i&lt;form.length;i++) { oErrorArray[i].innerHTML = ""; if(form[i].value="")){ oErrorArray[i].innerHTML = "Error - input field is blank"; goForm = false; } } if(goForm == true) form.submit(); } function resetform(form){ form.reset(); } </script> Error reported by IE8 debugger: Expected ')' login.xml, line 29 character 30 (which is right after the first "form.length")

  • Is it possible to post to Facebook application Wall via JavaScript?

    - by Bess
    I have a Canvas Facebook app embedded via an iframe. I would like to include a feedback link which would encourage the user to leave a comment that would be added to the Application wall - this comment would open like a standard FB modal window. Is there anyway to post to to the Application Wall directly via JS? Everything I have found such as FB.Connect.StreamPublish(), only publishes to the users stream, I need to publish to the application stream. Thanks!

  • Radio buttons being reset in FF on cache-refresh

    - by Andrew Song
    (This is technically an addendum to an earlier StackOverflow question I had posted, but my original post asked a different question which doesn't really cover this topic -- I don't want to edit my older question as I feel this is different enough to merit its own page) While browsing my website in Firefox 3.5 (and only FF3.5), I come across a page with two radio buttons that have the following HTML code: <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/> This page renders as expected, with 'check1' checked and 'check2' unchecked. When I then go to refresh the page by pressing Control + R, the two radio buttons render, but they are both unchecked even though the raw HTML code is the same (as above). If I do a cache-miss refresh (via Control + F5 or Control + Shift + R), the page returns back to the way you'd expect it. This is not a problem in any other browser I've tried except FF3.5. What is causing these radio buttons to be reset on a normal refresh? How can I avoid this?

  • Patterns: Local Singleton vs. Global Singleton?

    - by Mike Rosenblum
    There is a pattern that I use from time to time, but I'm not quite sure what it is called. I was hoping that the SO community could help me out. The pattern is pretty simple, and consists of two parts: A singleton factory, which creates objects based on the arguments passed to the factory method. Objects created by the factory. So far this is just a standard "singleton" pattern or "factory pattern". The issue that I'm asking about, however, is that the singleton factory in this case maintains a set of references to every object that it ever creates, held within a dictionary. These references can sometimes be strong references and sometimes weak references, but it can always reference any object that it has ever created. When receiving a request for a "new" object, the factory first searches the dictionary to see if an object with the required arguments already exits. If it does, it returns that object, if not, it returns a new object and also stores a reference to the new object within the dictionary. This pattern prevents having duplicative objects representing the same underlying "thing". This is useful where the created objects are relatively expensive. It can also be useful where these objects perform event handling or messaging - having one object per item being represented can prevent multiple messages/events for a single underlying source. There are probably other reasons to use this pattern, but this is where I've found this useful. My question is: what to call this? In a sense, each object is a singleton, at least with respect to the data it contains. Each is unique. But there are multiple instances of this class, however, so it's not at all a true singleton. In my own personal terminology, I tend to call the factory method a "global singleton". I then call the created objects "local singletons". I sometimes also say that the created objects have "reference equality", meaning that if two variables reference the same data (the same underlying item) then the reference they each hold must be to the same exact object, hence "reference equality". But these are my own invented terms, and I am not sure that they are good ones. Is there standard terminology for this concept? And if not, could some naming suggestions be made? Thanks in advance...
