• Determine when using the VC90 compiler in VS2010 instead of VS2008?

  - by Dan

  Is there a (Microsoft-specific) CPP macro to determine when I'm using the VC9 compiler in Visual Studio 2010 as opposed to Visual Studio 2008? _MSC_VER returns the compiler version, so with VS2010 multi-targeting feature, I'll get the same result as with VS2008. The reason for wanting to know the difference is that I created a new VS2010 project which contains code removed from a larger project. I just left the VS2008 stuff "as is" since we're moving away from VS2008 "soon" anyway and I didn't want to go through the hassle of creating a vcproj file along with the new vcxproj. For now, I've just defined my own macro to indicate whether the code is compiled into its own DLL or not; it works just fine, but it would be nice if there were something slightly more elegant.

• Accessing parent 'this' inside a jQuery $.getJSON

  - by JP

  I'm going to assume that the overall structure of my code as it currently stands is 'best', otherwise this question gets too long, but if I've made any obvious mistakes (or if I've made life hard for myself) then please correct away! Using jQuery, I have a javascript 'class' set out something like this: function MyClass () { this.noise = "Woof" this.dostuff = function() { $.getJSON("http://cows.go",function(moo) { this.noise = moo.inEnglish; } } } var instance = new MyClass(); instance.doStuff() console.log(instance.noise) I'm expecting some kinda tea drinking moo in the console, but of course I'm getting an error about this.noise not being defined (because $.getJSON doesn't pass this through, right?) Any suggestions as to how to be able to affect instance.squeak for any and all instances of MyClass without interference?

• PHP and Apache environment variables

  - by Simon

  Hello, I want to pass an environment variable in linux to apache on start up. export MYVAR=5 --I define my environment variable on the command line PassEnv MYVAR --set apache to import the variable in apache config file apachectl restart --when I restart apache I don't get an error message. However I have noticed that if I do not create the environment variable in my first step, I get a warning message, so must be working here echo $_SERVER['MYVAR'] --i try to access the environment variable within PHP but it is not defined I've observed that if I try to PassEnv an environment variable that already exits (one that I havn't created myself) it works fine. The SetEnv directive also works fine. I'd really like to pass an environment variable to apache on the fly without writing it in a file. Help much appreciated. I'm using CentOS, PHP5 and Apache2. Thanks.

  - by Marcos

  Hello all. I have a little problem with my regular expression, that I use in PHP. My code identify all tags of my content and add a link in this image. My code is working when I use dinamycally, without any defined image. When I try with a imapge path, the code does not work. How can I solve this problem? Working code: $content = preg_replace('/(<img .*?src="(.+?)".*?>)/','<a class="nyromodal foto" href="'.$imagem_wordpress.'">\1</a>', $content); Problem code: $content = preg_replace('/(<img .*?src="ttp://mysite.com/files/2010/04/bac-gallery-site-matters-saline-project1.jpg".*?>)/','<a class="nyromodal foto" href="'.$imagem_wordpress.'">\1</a>', $content);

• How do I list all non-system stored procedures?

  - by bubbassauro

  I want to create a query to list of all user defined stored procedures, excluding the ones that are system stored procedures, considering that: Checking the name like "sp_" doesn't work because there are user stored procedures that start with "sp_". Checking the property is_ms_shipped doesn't work because there are system stored procedures that have that flag = 0, for example: sp_alterdiagram (it is not MSShipped but appears under System Stored Procedures in SQL Server Management Studio). There must be a property, or a flag somewhere since you can see the "System Stored Procedures" in a separate folder in SQL 2005. Does anyone know? Edit: A combination of the suggestions below worked for me: select * from sys.objects O LEFT OUTER JOIN sys.extended_properties E ON O.object_id = E.major_id WHERE O.name IS NOT NULL AND ISNULL(O.is_ms_shipped, 0) = 0 AND ISNULL(E.name, '') <> 'microsoft_database_tools_support' AND O.type_desc = 'SQL_STORED_PROCEDURE' ORDER BY O.name

• How to make columns as wide as the widest entry?

  - by Helper Method

  For a gcc cheatsheet I'm writing, I want to create a table which should describe how gcc interprets different file endings. The table I created so far is defined as follows: |====================================================================== |.c |C source code which must be preprocessed. |.i |C source code which should not be preprocessed. |.h |C header file to be turned into a precompiled header. |.s |Assembler code. |other | An object file to be fed straight into linking. Any file name with no recognized suffix is treated this way. |====================================================================== The problem I have is that the table spans the total page width, but what I want is that each column only is as wide as it's widest entry, and that the table will span only as much witdh as it needs.

• Change MS Patch custom language

  - by nelusan

  How can I change the default UI language when installing a patch/update? The problem is that the patch takes the initial language in which the setup to be patched was installed and not the current system language (defined in Reginal Settings/Advanced Options). I wonder if there is a property or switch that I can pass to a msp file to change its UI language. Example: I created 'setup_v00.exe' (english and french) and a patch 'update_v00_v01.exe' (english and french); with system language = english, 'setup_v00.exe' installs in english; change system language in french; with system language = french, 'update_v00_v01.exe' still installs in english but I want it to install with a french interface;

• Navigation Within TabController

  - by David.Chu.ca

  I am trying to use UITabController as may controller in my main window and add navigation controllers to some tab bar items. For example, the first tab has a navigation controller with table view: ![alt text][1] The SettingsViewController is associated with its own NIB file, where a table view is defined. Within that xib file, I have a table view and set it to the outlet of SettingsViewController class property myTableView. The problem is that in the main xib file, for the SettingsViewController navigation, there is one outlet myTableView. I am not sure if I have to set this to somewhere? The exception I get is "[UIViewController _loadViewFromNibNamed:bundle:] loaded the "SettingsViewController" nib but the view outlet was not set." [1]:

• Is it possible to set ContentType for a WCF WebGet method?

  - by James Cadd

  I'm working with a WCF restful/http method that returns a stream of image data. I want to make sure that the content type is marked as "image/png". The method is defined as: [ServiceContract] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)] public class TileImageService { [WebGet(UriTemplate = "{id}")] public Stream GetTileImage(string id) { Bitmap bmp = new Bitmap(173, 173); Graphics g = Graphics.FromImage(bmp); g.Clear(Color.Blue); g.DrawString(DateTime.Now.ToLongTimeString(), new Font("Chiller", 20), Brushes.White, new PointF(10, 10)); g.Flush(); MemoryStream ms = new MemoryStream(); bmp.Save(ms, ImageFormat.Png); ms.Seek(0, SeekOrigin.Begin); return ms; } } In Firefox it looks like the content type is marked as application/octet stream. Is there a way to change the content type?

• advanced python autovivification

  - by Zhang18

  This question is about implementing the full PERL autovivification in python. I know similary questions were asked before and so far the best answre is http://stackoverflow.com/questions/635483/what-is-the-best-way-to-implement-nested-dictionaries-in-python/652284#652284. However, I'm looking to do this: a['x']['y'].append('z') without declaring a['x']['y'] = [] first, or rather, not declaring a['x'] = {} either. I know dict and list classes sorta don't mix so this is hard, but I'm interested in seeing if someone has an ingenius solution probably involving creating an inherited class from dict but defined a new append method on it? I also know this might throw off some python purists who will ask me to stick with Perl. But even just for a challenge, I'd like to see something. thx!

• When to release the UIImage ?

  - by ragnarius

  I use the following code to draw a subimage UIImage* subIm = getSubImage( large, rect ); [subIm drawInRect:self.bounds]; where getSubImage is defined as follows UIImage* getSubImage(UIImage* uim, CGRect rc){ CGImageRef imref = CGImageCreateWithImageInRect(uim.CGImage, rc); UIImage* sub = [UIImage imageWithCGImage:imref]; CGImageRelease(imref); NSLog(@"subimage retainCount=%d", [sub retainCount]); // is 1 return sub; }//getSubImage Is the code correct? Is it safe to "CGImageRelease" imref? Has sub "CGImageRetained" imref? Should I release subIm (I get an error if I do)? Is subIm contained in the autorelease-pool, and , if so, how do I know this? In general, can one check if an object is contained in the autorelease pool (for debugging purpose)?

• Returning S_FALSE from a C# COM dll

  - by AntonyW

  I have a method defined in IDL as follows : interface IMyFunc : IDispatch { [id(1), helpstring("method GetNextFunction")] HRESULT GetNextFunction([in,out] long* lPos, [out, retval] BSTR* bstrName); } Using C++ I always implemented this as follows : STDMETHODIMP CMyFunc::GetNextFunction(long *nID, long *lPos, BSTR *bstrName) { if ( function to return ) { // setup return values; return S_OK; } else { // just exit return S_FALSE; } } Now I am implementing this in C# and have used tlbimp on the type library and ended up with : public string GetNextFunction(ref int nID, ref int lPos) I understand that this is because [out, retval] is used as the return type instead of the HRESULT as in C++. Is there a simple way to return the S_OK / S_FALSE values without changing the method definition? The only way I can see is that I have to use ildasm / ilasm to add preservesig so I end up with something like this : public int GetNextFunction(ref int nID, ref int lPos, ref string bstrName) I was wondering if there was some other way without doing the il compilation step.

• Internet Explorer 8 EmulateIE7 Mode not working

  - by Ryu

  I've set up IIS6 to send the following headers Custom Header Name: X-UA-Compatible Custom Header Value: IE=EmulateIE7 that supposed to force IE 8 into IE 7 Compatibility mode. You can read more about it on MSDN . I have noticed by looking in the Developer toolbar that if I have a DTD defined the document mode correctly gets set to IE 7, but the browser mode is IE 8. If the page doesn't have a DTD the document mode gets set to Quirks and Browser Mode once again IE 8. Am I doing something wrong. How do I force IE 8 to set IE 7 Browser mode. Thanks

• Compiler #defines for g++ and cl

  - by DHamrick

  I am writing a program that is cross platform. There are a few spots where I have to specify an operating system dependent call. #ifdef WINDOWS ..do windows only stuff #endif #ifdef LINUX ..do linux only stuff #endif Are there any preprocesser directives that get defined by the compiler so I don't have to explicitly define them when I use the command line compiler. ie. cl -DWINDOWS program.cpp or g++ -DLINUX program.cpp I realize I could easily write a makefile or have a shell/batch script that will do this automatically. But I would prefer to use the same ones as the compiler (if they exist) by default.

• HTTPS and HTTParty - Timeout and EOF

  - by ferparra

  Hi all, I'm trying to post something to an HTTPS resource, but it seems it doesn't work. My code look something like this: require 'httparty' class MyClass include HTTParty base_uri "https://mydomain.com:8085/search" basic_auth 'admin', 'changeme' format :xml def mymethod self.class.post('/job', :query => {:search => "*"}) end end As you can see, I've defined an URI with 'https' included, so it should set the use_ssl property for the Net::HTTPS library automatically. For some reason, Net::HTTP is requested, and I never get in touch with the server, so I end up with an EOF. Any clues?

• android html download and parse error

  - by Brahadeesh

  I am trying to download the html file using the ul of the page. I am using Jsoup. This is my code: TextView ptext = (TextView) findViewById(R.id.pagetext); Document doc = null; try { doc = (Document) Jsoup.connect(mNewLinkUrl).get(); } catch (IOException e) { Log.d(TAG, e.toString()); e.printStackTrace(); } NodeList nl = doc.getElementsByTagName("meta"); Element meta = (Element) nl.item(0); String title = meta.attr("title"); ptext.append("\n" + mNewLinkUrl); When running it, I am getting an error saying attr is not defined for the type element. What have I done wrong? Pardon me if this seems trivial.

• Choosing a design pattern for a class that might change it's internal attributes

  - by the_drow

  I have a class that holds arbitrary state and it's defined like this: class AbstractFoo { }; template <class StatePolicy> class Foo : public StatePolicy, public AbstractFoo { }; The state policy contains only protected attributes that represent the state. The state might be the same for multiple behaviors and they can be replaced at runtime. All Foo objects have the same interface to abstract the state itself and to enable storing Foo objects in containers. I would like to find the least verbose and the most maintainable way to express this.

• Using Report (Reporting Services) parameter values in ASP.NET page

  - by noup

  I have a report (Reporting Services) integrated into an ASP.NET that shows dropdownlists to select report parameter values. The dropdownlists are populated using direct database selects, though I see the report RDL files do contain the paramter values and datasets as defined in the report designer. Is it possible to obtain the report parameters "available values" in ASP.NET to populate the dropdownlists? This would avoid some code duplication. Update If the parameter doesn't use a query for available values, the following works: foreach (ValidValue value in this.ReportViewerControl.ServerReport.GetParameters()["myParameter"].ValidValues) { this.DropDownListControl.Items.Add(new ListItem(value.Label, value.Value)); } Still haven't found a way to access report datasets though...

• core-plot and NSDate (iPhone)

  - by Urizen

  I wish to plot a line graph where the x-axis is defined as a number of days between two dates and the y-axis is a value that varies on each of the days. I can plot the y values as an NSNumber but I have no idea how to set the ranges and the markup on the x-axis. I have looked at the date example in the "examples" directory of the core-plot distribution but have found it a little confusing. Does anyone know of a tutorial, or code sample, which might asist me in this regard? Thank you in advance.

• Why does C's "fopen" take a "const char *" as its second argument?

  - by Chris Cooper

  It has always struck me as strange that the C function "fopen" takes a "const char *" as the second argument. I would think it would be easier to both read your code and implement the library's code if there were bit masks defined in stdio.h, like "IO_READ" and such, so you could do things like: FILE* myFile = fopen("file.txt", IO_READ & IO_WRITE); Is there a programmatic reason for the way it actually is, or is it just historic? (i.e. "That's just the way it is.")

• Access to an inner type

  - by sohum

  A colleague of mine posted a question on an internal forum which got me thinking about whether this was possible through C#. Basically, he's got an interface as follows: public interface IProvider<T> { T GetT(); } Is it possible to use something that implements that interface as a type parameter to another generic class and have access to the type T without re-specifying it? For example: public class Foo<P> where P : IProvider<T> { P p; T GetInnerT() { return p.GetT(); } } This does not compile, because the type T is not defined and hence can't be used as a parameter for IProvider. Is something like this even possible? Just curious!

• Navigating from VB.NET code to C# code problem

  - by user181218

  Hi, There seemes to be a consistent problem with the following situation: Say you have a VS2008 solution, consisting of a (say console) application written in vb.net, and a class library written in c#. The application references the class library project. This, of course, complies and works well. However, when you right-click (in the vb.net application code) a function prototype/object type defined in the class library, and select "Go to definition", the object browser opens providing you with the the list of methods available for the class the class library consists of. BAD. However, if you try to do the same when both the application and cl are in c#, this works just fine and you navigate driectly to the relevant function/class.GOOD. Known issue? Solvable?

• Help System.Web.Compilation.BuildManager find a type in a non-referenced assembly

  - by asbjornu

  I'm trying to write a plug-in system where assemblies can be dropped in a folder that ASP.NET has no knowledge about. This plug-in system works fine for ASP.NET MVC based assemblies, but for old-school WebForm assemblies (where the .aspx files Inherits the System.Web.UI.Page derived classes) System.Web.Compilation.BuildManager is responsible for compiling the .aspx file into a dynamic assembly. My problem is that the BuildManager knows nothing about the assemblies within my plug-in folder and it seems to be absolutely nothing I can do to help it. If I do: BuildManager.GetType("Type.Defined.In.Plugin.Assembly", true, true) it throws. If I first get a reference to the Type and then try: var instance = BuildManager.CreateInstanceFromVirtualPath(path, type); it still throws, even though I've now passed in the specific type it needs to compile the .aspx file. Is there anything I can do to help BuildManager find the types it needs to compile the .aspx file?
