Library A has an init function ( A_init , defined in A/initA.cpp ), that is called from library B 's init function ( B_init , defined in B/initB.cpp ), which is called from C 's main. Thus, when linking B , A_init (and all symbols

To achieve this i want my app to keep the BLE device data in shared preferences or somewhere. After app close, i'd like my app to retrive this data and attemp a connection without scan for devices. I prefer to avoid scanning every time becouse scan gives me a lot of problems and it takes time. How can do it? Is there a way to save BLE data? 回答1: You need to store the Bluetooth Device Address (AB:CD:EF:01:02:03) of the device in

I'm running an MSBuild script and don't want it clogging up my log on my build server. I'd rather not have to add "SET NOCOUNT ON" in every script, so if there's a way to do it from the command line, that would be fantastic. 回答1: What about creating a startup script with SET NOCOUNT ON in the script (assign the script to the SQLCMDINI environment variable). http://msdn.microsoft.com/en-us/library/ms162773.aspx 回答2: The -i and -q options are mutually exclusive .

In the documentation for keychain access it states: On iPhone, Keychain rights depend on the provisioning profile used to sign your application. Be sure to consistently use the same provisioning profile across different versions of your application. Because my Provisioning Profile was expiring, I renewed it (in the provisioning portal), downloaded it, and double-clicked it which "installed" it into XCode's organizer.

In the collectionView cellForItemAtIndexPath: method, it creates a series of custom cells based on the datasource. The custom cells in turn contain a UIView, subclassed to draw single PDF pages. It's set up in such a way as to split a PDF file into its single pages, so cell 1 contains PDF page 1, cell 2 contains PDF page 2 and so on. So far so good, here's my problem: When I scroll down, the UICollectionView starts displaying the wrong cells. For instance in a 34 page document,

I'm wondering if this is a bug with the new experimental Module feature for Clang -- maybe a problem with the implementation of module maps for the standard library -- or if there's something I'm doing wrong. The error still appears if I add -fbuiltin-module-map to the command. Interestingly, the error no longer appears if I substitute stdint.h for

Is there a mechanism that would allow me to do this? To clarify, here is an example: class A { public : A (){} initialize ( int x ) { c = x ; } private : const int c ; } I want to be able to do something like that. I don't have this information at construction, so I can't simply move initialization to the initialization list of the constructor. 回答1: No, you cannot
