• Glew in VS 2010: unresolved external symbol __imp__glewInit

  - by NoviceCai

  I am learning OpenGL by following the redbook. When I come to around page 90, I need use glGenBuffers(); Then I need install "glew". By following the steps in www.cs.uiowa.edu/~cwyman/classes/common/howto/winGLUT.html I download glew.zip from glew.sourceforge.net/ and unpack the files. I put glew.h in C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include and put glew32.lib in C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Lib and put glew32.dll in C:\Windows\System32. After that, I build my project in VS 2010 and in Linker-input, I add dependencies glew32.lib. But when I build it, I have error unresolved external symbol _imp_glewInit I spend whole day to search solutions, but did not find one. Hope someone can help me with this.

• Apple Magic Trackpad Gestures carried out as personalized Commands in Windows

  - by Adele

  I want to have the Apple Magic Trackpad to work on Windows, but NOT as a regular Mouse! I will need the normal Trackpad Gestures to work with a c# Application (i.e. when carring out a 2 finger swipe to the left, it will start playing a song...). I guess I´ll have to write my own driver? Is there a way to use Apples MAgic Trackpad Driver for Windows and re-write that one? OR is there any way (API, self-written driver), so that I could just hook the gestures to my Commands? Or any RAW Input examples? Does anybody know how to do that, or where to start? Thank you so much, I´m really lost.

• Why isn't UTF-8 allowed as the "ANSI" code page?

  - by dan04

  The Windows _setmbcp function allows any valid code page... (except UTF-7 and UTF-8, which are not supported) OK, not supporting UTF-7 makes sense: Characters have non-unique representations and that introduces complexity and security risks. But why not UTF-8? As I understand it, the "ANSI" versions of the Windows API functions convert their arguments to UTF-16, call the equivalent "W" function, and convert any strings in the output to "ANSI". This is what I've been doing manually. So why can't Windows do it for me?

• What's an easy way to set up object communication in Obj-C?

  - by seaworthy

  I am trying to send a slider value from a controller object to a method of a model object. The later is implemented in the separate file and I have appropriate headers. I think the problem is that I am not sure how to instantiate the receiver in order to produce a working method for the controller. Here is the controller's method. -(IBAction)setValue:(id)slider {[Model setValue:[slider floatValue]];} @implementation Model -(void)setValue:(float)n{ printf("%f",n); } @end What I get is 'Model' may not respond to '+setValue' warning and no output in my console. Any insight is appreciated.

• Statement hierarchy in programming languages

  - by sudo

  I quickly wrote an interpreter for some sort of experimental programing language i came up with, in PHP (yes, in PHP). The language itself doesn't have anything really special, I just wanted to give it a try. I got the basic things working (Hello World, input to output, string manipulation, arithmetics) but I'm getting stuck with the management of blocks and grouped statements. What I mean is: PHP and most other languages let you do this: ((2+2)*(8+2)+2), of course not only with mathematical computations. My program structure currently consists of a multidimensional array built like this: ID => Type (Identifier, String, Int, Newline, EOF, Comma, ...) Contents (If identifier, int or string) How could I allow statements to be executed in a defined order like in the PHP example above?

• Configuring a library to be included with C++ test

  - by vrish88

  Hello, I would like to utilize the UnitTest++ library in a testing file. However, I am having some difficulty getting the library to be included at compile time. So here is my current directory structure: tests/ UnitTests++/ libUnitTest++.a src/ UnitTests++.h unit/ test.cpp I have just used the UnitTest++ getting started guide to just get the library setup. Here is test.cpp: // test.cpp #include <UnitTest++.h> TEST(FailSpectacularly) { CHECK(false); } int main() { return UnitTest::RunAllTests(); } And I am currently trying to compile with: gcc -lUnitTest++ -L../UnitTest++/ -I../UnitTest++/src/ test.cpp I am currently getting a bunch output with ld: symbol(s) not found at the end. So how would I be able to get the UnitTest++ library properly included when this program is compiled? I am on a Mac and I'd also like for there to be an easy way for people on a Linux machine to run these same tests. Whew, I hope this provides enough information, if not please let me know.

• FFmpeg bitrate issue.

  - by user329840

  I'm dealing with a very big issue about bit rate , ffmpeg provide the -b option for the bit rate and for adjustment it provide -minrate and -maxrate, -bufsize but it don't work proper. If i'm giving 256kbps at -b option , when the trans-coding finishes , it provide the 380kbps. How can we achieve the constant bit rate using ffmpeg. If their is +-10Kb it's adjustable. but the video bit rate always exceed by 50-100 kbps. I'm using following command ffmpeg -i "demo.avs" -vcodec libx264 -s 320x240 -aspect 4:3 -r 15 -b 256kb \ -minrate 200kb -maxrate 280kb -bufsize 256kb -acodec libmp3lame -ac 2 \ -ar 22050 -ab 64kb -y "output.mp4" When trans-coding is done, the Media Info show overall bit rate 440kb (it should be 320kb). Is their something wrong in the command. Or i have to use some other parameter? Plz provide your suggestion its very important.

• ASCII in Windows XP and Ubuntu Linux

  - by Mikey D

  I've made a program in MVSC++ which outputs memory contents (in ASCII). The ASCII I see in windows console seem to match what I see in various ASCII tables (smiley, diamond, club, right arrow etc). This program needs to compile under Linux (which is does), but the ASCII output looks completely different. A few symbols are the same but the rest are so different. Is there any way to change how terminal displays ASCII code? EDIT: The program executes correctly, it's just the ASCII that is being displayed differently.

• What's the environment variable for the path to the desktop?

  - by Scott Langham

  I'm writing a Windows batch file and want to copy something to the desktop. I think I can use this: %UserProfile%\Desktop\ However, I'm thinking, that's probably only going to work on an English OS. Is there a way I can do this in a batch file that will work on any internationalized version? UPDATE I tried the following batch file: REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v Desktop FOR /F "usebackq tokens=3 skip=4" %%i in (`REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v Desktop`) DO SET DESKTOPDIR=%%i FOR /F "usebackq delims=" %%i in (`ECHO %DESKTOPDIR%`) DO SET DESKTOPDIR=%%i ECHO %DESKTOPDIR% And got this output: S:\REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v Desktop HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders Desktop REG_EXPAND_SZ %USERPROFILE%\Desktop S:\FOR /F "usebackq tokens=3 skip=4" %i in (`REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folder s" /v Desktop`) DO SET DESKTOPDIR=%i S:\FOR /F "usebackq delims=" %i in (`ECHO ECHO is on.`) DO SET DESKTOPDIR=%i S:\SET DESKTOPDIR=ECHO is on. S:\ECHO ECHO is on. ECHO is on.

• bash: hwo to know NUM option in grep -A -B "on the fly" ?

  - by Michael Mao

  Hello everyone: I am trying to analyze my agent results from a collection of 20 txt files here. If you wonder about the background info, please go see my page, what I am doing here is just one step. Basically I would like to take only my agent's result out of the messy context, so I've got this command for a single file: cat run15.txt | grep -A 50 -E '^Agent Name: agent10479475' | grep -B 50 '^==' This means : after the regex match, continue forward by 50 lines, stop, then match a line separator starts with "==", go back by 50 lines, if possible (This would certainly clash the very first line). This approach depends on the fact that the hard-coded line number counter 50, would be just fine to get exactly one line separator. And this would not work if I do the following code: cat run*.txt | grep -A 50 -E '^Agent Name: agent10479475' | grep -B 50 '^==' The output would be a mess... My question is: how to make sure grep knows exactly when to stop going forward, and when to stop getting backward? Any suggestion or hint is much appreciated.

• Reading a triangle of numbers into a 2d array of ints in Python

  - by Gabriel Silk

  I want to read a triangle of integer values from a file into a 2D array of ints using Python. The numbers would look like this: 75 95 64 17 47 82 18 35 87 10 20 04 82 47 65 ... The code I have so far is as follows: f = open('problem18.input', 'r') arr = [] for i in range(0, 15): arr.append([]) str = f.readline() a = str.split(' ') for tok in a: arr[i].append(int(tok[:2])) print arr I have a feeling this could be done in a tighter, more Pythonesque way. How would you do it?

• How does one pre-populate a Python Formish form?

  - by Jace

  How does one pre-populate a Formish form? The obvious method as per the documentation doesn't seem right. Using one of the provided examples: import formish, schemaish structure = schemaish.Structure() structure.add( 'a', schemaish.String() ) structure.add( 'b', schemaish.Integer() ) schema = schemaish.Structure() schema.add( 'myStruct', structure ) form = formish.Form(schema, 'form') If we pass this a valid request object: form.validate(request) The output is a structure like this: {'myStruct': {'a': 'value', 'b': 0 }} However, pre-populating the form using defaults requires this: form.defaults = {'myStruct.a': 'value', 'myStruct.b': 0} The dottedish package has a DottedDict object that can convert a nested dict to a dotted dict, but this asymmetry doesn't seem right. Is there a better way to do this?

• st-ordering library function?

  - by chang

  I'm in the search for an implementation of an ear-decomposition algorithm (http://www.ics.uci.edu/~eppstein/junkyard/euler/ear.html). I examined networkx and didn't find one. Although the algorithm layout is vaguely in my mind, I'd like to see some reference implementation, too. Side problem: First step could be an st-ordering of a graph. Are there any implementations for st-ordering algorithms you know? Thanks for your input. I'd really like to contribute e.g. to networkx by implementing the ear-decomposition algorithm in python.

• How to lock the Screen customly? Just like WaveSecure in Android

  - by HackNone

  I want to do a demo just like WaveSecure, which win Android Develop Challenge 2 with a third place. Now I have a problem in locking the screen customly, so I want to know how WaveSecure achieve its locking function, as the following picture show: http://goo.gl/XlPP When the mobile is locked, WaveSecure can require customer to input their own password. So I think WaveSecure must replace Android's original locking function. And I also google it, but I didn't find anything helpful. I only find two packages may be helpful. They are: android.app.KeyguardManager android.os.PowerManager But after I reading the Android Docs, I still can't have an idea on it. Can you help me? Thx:)

• Replacement for Azure SDK Powershell commandlets for deployments

  - by Frank Rosario

  Hi, We've run into an issue with the New-Deployment Azure Powershell commandlet timing out; we've put in a bug report with MS. While they gave us an explanation for it (the path and timeout threshold used to upload through commandlets is different then what's used by the web portal); they don't have a fix for us. We need to get this running so we can automate our build deployments, so we're looking into developing a custom commandlet to replace New-Deployment using the Azure SDK; hoping this path will not have the timeout issues the commandlet did. But before we go down that route; are there any other scriptable tools I can use to replace the New-Deployment functionality? I looked at Cloudberry for Windows Azure; but that doesn't have a scriptable interface yet. Any constructive input is greatly appreciated.

• How do I inhibit "note C6311" in Microsoft C compiler?

  - by piCookie

  In this maximally clipped source example, the manifest constant FOOBAR is being redefined. This is deliberate, and there is extra code in the live case to make use of each definition. The pragma was added to get rid of a warning message, but then a note appeared, and I don't seem to find a way to get rid of the note. I've been able to modify this particular source to #undef between the #define, but I would like to know if there's a way to inhibit the note without requiring #undef, since there are multiple constants being handled the same way. #pragma warning( disable : 4005 ) // 'identifier' : macro redefinition #define FOOBAR FOO #define FOOBAR BAR The compiler banner and output are as follows Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 12.00.8804 for 80x86 Copyright (C) Microsoft Corp 1984-1998.

• HLSL How can one pass data between shaders / read existing colour value?

  - by RJFalconer

  Hello all, I have 2 HLSL ps2.0 shaders. Simplified, they are: Shader 1 Reads texture Outputs colour value based on this texture Shader 2 Needs to read in existing colour (or have it passed in/read from a register) Outputs the final colour which is a function of the previous colour (They need to be different shaders as I've reached the maximum vertex-shader outputs for 1 shader) My problem is I cannot work out how Shader 2 can access the existing fragment/pixel colour. Is the only way for shaders to interact really just the alpha blending options? These aren't sufficient if I want to use the colour as input to my function.

• documenting black-box test cases

  - by Blux

  Hi everyone, I want to write an initial (black box) test cases for one of my university projects. I haven't started coding yet, I'm still in completing the SRS document and i should specify the test cases i'm going to implement after the coding. The project is web based, and i should follow this template in each test case: +++++ Test case ID: Author: Initial state: Preconditions: Use Case: Test input: Expected output: ++++++ The thing is, i don't know what is the difference between "initial state" and "preconditions". In some of the test cases it's hard to differentiate between them. Like in "Edit Page" what should be the initial state and what should be the preconditions? any help will appreciated.=)

• How to create a tree with filtered nodes from drupal taxonomy.

  - by sprugman

  I'm trying to create a menu tree in drupal like this: - term 1 node 1 node 2 - sub-term 1 node 3 node 4 + sub-term 2 - sub-term 3 node 5 - sub-sub-term 1 node 6 + term 2 etc. (Sub-term 2 and term 2 are toggled closed.) Some requirements: Output this using something like JQuery Menu to get an interactive tree Filter the nodes by cck type Filter the nodes by cck field Only have terms with nodes or other active terms in them show up Mark the current node as such, and automatically open the tree to that point Do I have to write this myself, or are there a combination of modules that can do it? I've got Advanced Taxonomy Blocks, which is pretty close, but it doesn't list the nodes.

• What is "sentry object" in C++?

  - by Romain Hippeau

  I answered this question, and Potatoswatter answered too as The modern C++ equivalent would be a sentry object: construct it at the beginning of a function, with its constructor implementing call(), and upon return (or abnormal exit), its destructor implements I am not familiar with using sentry objects in C++. I thought they were limited to input and output streams. Could somebody explain to me about C++ sentry objects as well as how to use them as an around interceptor for one or more methods in a class ? i.e. How to do this ? Sentry objects are very similar indeed. On the one hand they require explicit instantiation (and being passed this) but on the other hand you can add to them so that they check not only the invariants of the class but some pre/post conditions for the function at hand.

• OJB / Oracle XE sql debug-display problem

  - by Jay

  Hello, I have a Java application, and use OJB as my ORM technology. I have an Oracle XE installation locally to develop against. The problem is when I need to debug a problem, I like looking at the SQL output. Here is an example of SQL I can view through the "Top SQL" interface in Oracle XE: select a_bunch_of_fields from KREW_DOC_TYP_T A0 WHERE ((UPPER(A0.DOC_TYP_NM) LIKE :1) AND A0.ACTV_IND = :2) AND A0.CUR_IND = :3 The problem is I would like to see the real value instead of ":1". I can't seem to find how I can configure this. I know the real values are working, because the application is responding as expected, for the most part (hence the bugs I am working on). Thanks, Jay
