  • Visual Studio 2008 compiles anything in C++ file?

    - by Brad Pepers
    I noticed today that a source code file in a project was compiling even though it had junk at the top of it. It got me wondering what all would pass without error through the compiler. Here is an example of code that will not generate any error messages: what kind of weird behaviour is this??? #include "stdafx.h" // what is up? int foo(int bar) { bla bla bla????? return bar; } and more junk??? What in the world is the compiler doing to allow this code to compile without giving any error messages? I'm using Visual Studio 2008 and this is unmanaged C++ code. The foo function isn't actually generated in the object file so it can't be used but why no errors???

  • How to read tags out of m4a files in .NET?

    - by dkackman
    I've got some heavily modified code that ultimately came from the Windows Media SDK that works great for reading tags out of MP3 and WMV files. Somewhere along the line, Windows Media Player added support for .m4a files (was it in Windows 7?) but the Windows Media API doesn't seem to reflect that addition (or at least IWMMetadataEditor2::OpenEx pukes on an .m4a file). What would be some good C# code or links on how to dig meta data tags out of m4a files? (Google has come up dry on the C# front.) UPDATE AtomicParsley did indeed end being the best approach. Since that code is a command line tool however I ended up having to create a managed wrapper around some of its functionality in order to use in-process. It is posted on google code if anyone else needs such a thing.

  • Very very weird problem with UIImageView property - I can access it then I can't, and it's not nil.

    - by just_another_coder
    Very very weird problem with UIImageView property on iPad application @interface MyViewController : UIViewController { IBOutlet UIImageView* coverImage; } @property(nonatomic, retain) IBOutlet UIImageView* coverImage; … more code @implementation MyViewController @synthesize coverImage; … more code - (void)viewDidLoad { [super viewDidLoad]; NSString* imageName = @"my_image.png"; UIImage* tempImage = [UIImage imageNamed:imageName]; [self.coverImage setImage:tempImage]; } The above code WILL display the image. In another part of code: -(IBAction) stopButtonPressed:(id)sender { [self.coverImage setHidden:YES]; NSLog(@"coverImage desc: %@", [coverImage description]); } The image will NOT disappear. I know the reference to the image isn't nil, because it gives me this output: 2010-05-29 17:37:40.706 MyApp[95360:207] coverImage desc: UIImageView: 0x5128420; frame = (0 0; 1024 768); autoresize = RM+BM; userInteractionEnabled = NO; layer = CALayer: 0x512bed0 In addition, if I move the code in viewDidLoad to another part of the class, and try to execute it from there, it fails to show the image at all.

  • Browser gets blocked, workers to the rescue?

    - by tb_selleo
    Hello, I use JavaScript for rendering 20 tables of 100 rows each. The data for each table is provided by controller as JSON. Each table is split into section that have "totals" and have some other JavaScript logic code. Some totals are outside of the table itself. As a result JavaScript blocks browser for a couple of seconds (especially in IE6) :( I was consideting to use http://code.google.com/p/jsworker/, however Google Gears Workers (I guess workers in general) will not allow me to make changes to DOM at the worker code, and also it seems to me that I can not use jQuery inside jsworker worker code. (Maybe I am wrong here?). This issue seems to be fundamental to the JavaScript coding practice, can you share with me your thoughts how to approach it?

  • VS2005 SQL Syntax highlighting is incorrect for nested comments?

    - by MattH
    I'm working with VS2005, and SSMS 2005. SQL Server allows nested comments as follows: /* Comment 1 /* Comment 2 */ Some commented out code here */ This code runs fine. However if putting the above into a .sql file in VS2005, it incorrectly shows the commented out code as 'active', (its not green). It seems that StackOverflow has highlighted the code in the same way. Is this a bug in VS2005? Or does SSMS handle nested comments differently compared to the ANSI SQL standards? Can someone clarify this discrepancy, and if it appears to be a bug, if there a way to fix the syntax highlighting?

    I want to know about the name of all currently opened MS-Word file by its unique id. I found unique id for one file but when I gave its destination path in code. My requirement is that when any user open Word file then the unique id of this file is passed into my code and through this code the name of this file is stored into database (but it is done backgroundly and for multiple files).

  • Where does Subversion physically stores its DataBase ?

    - by Mika Jacobi
    After reading many introductions, starting guides, and documentation on SVN, I still cannot figure out where is my versioning data stored. I mean physically. I have over 3 GB of code checked in, and the repo is just a few MB large. This is still Voodoo for me. And, as a coder, I don't really believe in Magic. EDIT : A contributor stated that not all the code was stored in the repo, is that true ? I mean, if I delete my local working copy I still can get back my source code for the repository... If so, I still can't understand how such a compression can occur on my code...

  • C# 3 dimensional array definition issue

    - by George2
    Hello everyone, My following code has compile error, Error 1 Cannot implicitly convert type 'TestArray1.Foo[,,*]' to 'TestArray1.Foo[][][]' C:\Users\lma\Documents\Visual Studio 2008\Projects\TestArray1\TestArray1\Program.cs 17 30 TestArray1 Does anyone have any ideas? Here is my whole code, I am using VSTS 2008 + Vista 64-bit. namespace TestArray1 { class Foo { } class Program { static void Main(string[] args) { Foo[][][] foos = new Foo[1, 1, 1]; return; } } } EDIT: version 2. I have another version of code, but still has compile error. Any ideas? Error 1 Invalid rank specifier: expected ',' or ']' C:\Users\lma\Documents\Visual Studio 2008\Projects\TestArray1\TestArray1\Program.cs 17 41 TestArray1 Error 2 Invalid rank specifier: expected ',' or ']' C:\Users\lma\Documents\Visual Studio 2008\Projects\TestArray1\TestArray1\Program.cs 17 44 TestArray1 namespace TestArray1 { class Foo { } class Program { static void Main(string[] args) { Foo[][][] foos = new Foo[1][1][1]; return; } } } EDIT: version 3. I think I want to have a jagged array. And after learning from the fellow guys. Here is my code fix, and it compile fine in VSTS 2008. What I want is a jagged array, and currently I need to have only one element. Could anyone review whether my code is correct to implement my goal please? namespace TestArray1 { class Foo { } class Program { static void Main(string[] args) { Foo[][][] foos = new Foo[1][][]; foos[0] = new Foo[1][]; foos[0][0] = new Foo[1]; foos[0][0][0] = new Foo(); return; } } } thanks in advance, George

  • How do you keep application logic separate from UI when UI components have built-in functionality?

    - by Al C
    I know it's important to keep user interface code separated from domain code--the application is easier to understand, maintain, change, and (sometimes) isolate bugs. But here's my mental block ... Delphi comes with components with methods that do what I want, e.g., a RichText Memo component lets me work with rich text. Other components, like TMS's string grid not only do what I want, but I paid extra for the functionality. These features put the R in RAD. It seems illogical to write my own classes to do things somebody else has already done for me. It's reinventing the wheel [ever tried working directly with rich text? :-) ] But if I use the functionality built into components like these, then I will end up with lots of intermingled UI and domain code--I'll have a form with most of my code built into its event handlers. How do you deal with this issue? ... Or, if I want to continue using the code others have already written for me, how would you suggest I deal with the issue?

    Hi, I want to mix audio files of different size into a one single .wav file. There is a sample through which we can mix files of same size [(http://www.modejong.com/iOS/#ex4 )(Example 4)]. I modified the code to get the mixed file as a .wav file. But I am not able to understand that how to modify this code for unequal sized files. If someone can help me out with some code snippet,i'll be really thankful.

  • Strange behavior with ajax call complete in JavaScript modules

    - by user2598794
    I have 3 simple modules with JavaScript code and JQuery ajax call. First module lots.js: var Lots = (function ($) { var self = this; var processIsRunning; return { getLots: function (lotsUrl) { var items = []; self.processIsRunning = true; var request = $.ajax({ url: lotsUrl, type: 'POST', success: function (data) { //some code } }); $.when(request).done(function() { //some code self.processIsRunning = false; }); }, isComplete: function () { return !self.processIsRunning; } }; }(jQuery)); Module bids.js: var Bids = (function ($) { return { makeBids: function (bidUrl) { //some code } }; }(jQuery)); Module app.js which bundles all together: var App = (function () { var lots_url = null; var bid_url = null; var self = this; return { if (!self.lots_url) { self.lots_url = lotsUrl; } GetLots: function (lotsUrl) { Lots.getLots(self.lots_url); }, MakeBids: function makeBid(bidUrl) { //some code var isComp = Lots.isComplete(); while (!isComp) { isComp = Lots.isComplete(); } Bids.makeBids(self.bid_url); } }; }()); But in the 'while' loop I always get 'isComplete=false'. In debug I see that 'processIsRunning' in Lots module is always true. What's the problem?

  • JSLint reports unexpected use of '&' and '|' -- I'd like to clean this

    - by Zhami
    I'm trying to get my Javascript code 100% JSLint clean. I've got some JS code that I've lifted from elsewhere to create a UUID. That code has the following line: s[16] = hexDigits.substr((s[16] & 0x3) | 0x8, 1); This line incites JSLint to generate two error messages: 1) Unexpected use of '&' 2) Unexpected use of '|' I don't understand why -- I'd appreciate counsel regarding how to recode to eliminate the error message.

  • Upgrading From EF 4x to 6 breaks everything

    - by dan h
    Attempted to upgrade my project from EF4 to EF6, I get build errors It appears that if i swap out the namespaces manually to include the entity.core it works, but if i change the .edmx file at all, the code reverts back to the old references and i have to manually edit the code generation files to include the update namespace references. I have attempted to "add code generation item" that does not resolve the issue at all. When i open the .edmx file in the IDE it shows me everything correctly.

  • Problem with dynamically added script element - attribute src is empty

    - by Stazh
    Hi there, I have a problem with dynamically added script element (using jQuery). Code for adding new script element to DOM is this: var pScript = document.createElement("script"); pScript.type = "text/javascript"; pScript.src = sFile; // Add element to the end of head element $("head").append(pScript); The script is added with no problem, and the code runs perfectly. But, the problem occurs when I try to find the newly added script. I use this code to iterate through all script elements: var bAdd = true; $("script").each(function() { if(this.src == sFile) bAdd = false; }); (I need this code to prevent adding script that is already loaded) Problem is that all other script elements have src attribute set, but the newly added (dynamically) has not... Any idea?

  • Loading a Windows DLL in Java and initiate a class from it

    - by Joy
    I have a Windows DLL file from .NET namely "System.Management.dll". I work with it using the code I write below: ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_LogicalDisk WHERE Name = 'C:'"); foreach (ManagementObject queryObj in searcher.Get()) { Console.WriteLine("Win32_LogicalDisk instance: "); if (queryObj["VolumeSerialNumber"] != null) { Console.WriteLine("Drive Name : " + queryObj["Name"]); Console.WriteLine("VolumeSerialNumber:", queryObj["VolumeSerialNumber"]); SysdriveSerial = queryObj["VolumeSerialNumber"].ToString(); } } Now I need this piece of code to be in Java. So can I do this? Without anything like c++ unmanaged code. I don't want to use c++ unmanaged code to call to this dll. I want something like this : public class CallToCsharp { private static native void ManagementObjectSearcher(); public static void main(String[] args) { System.loadLibrary("System.Management"); System.out.println("Loaded"); ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_LogicalDisk WHERE Name = 'C:'"); } }
