If you change the active project to Android, the squiggles change: Since this is shared code, you should correct the code even though it compiles in the currently active configuration. Even though this line compiles when iOS is the active project, it won't compile when Android is the active project. Line 12 has a purple squiggle on the identifier BYE because this identifier isn't defined in the (currently) inactive Android.NativeActivity project. This is because no identifier HELLO is defined in the currently active iOS project. The greeting variable at line 11 is initialized with the identifier HELLO, which now has a red squiggle. The #ifdef branch on line 6 is grayed out to indicate an inactive region, because _ANDROID_ is not defined for the iOS project. ![]() In this image, the active project is iOS.StaticLibrary: ![]() The illustration shows shared code being edited. If you write some code that would result in an error in an inactive project, IntelliSense still shows squiggles, but they are in a different color than squiggles for errors in the current context.Ĭonsider an OpenGLES Application that's configured to build for Android and iOS. ![]() In a shared code project, some IntelliSense features such as squiggles are available even when you are working in an Android context. The settings that are specific to C++ begin with "C++" the other settings are for all languages. You can change the fonts for many UI windows here, not just the editor. The default colors and fonts can be changed in the Options dialog box, under Environment > Fonts and Colors. A red squiggle indicates a compiler error or warning in active code that you need to deal with. A purple squiggle appears in a shared project when there is an error in code that is not currently active, for example when you are working in the Windows context but enter something that would be an error in an Android context. A green squiggle appears when you write a forward declaration, to remind you that you still need to write the implementation. Squiggles under a program element (variable, keyword, brace, type name, and so on) call your attention to an error or potential error in the code. You can turn off Quick Info in the Options dialog box, under Text Editor > C/C++ > Advanced > Auto Quick Info. Hover over a function call to see the function's signature. When you hover the mouse cursor over a variable, a small window appears inline that shows the type information and the header in which the type is defined. You can turn off parameter information in the Options dialog box, under Text Editor > C/C++ > General > Parameter information. The "current" parameter-based on the cursor location-is in bold. When you type an opening brace of a function call, or angle bracket on a class template variable declaration, the editor shows a small window with the parameter types for each overload of the function or constructor. You can turn off member list in the Options dialog box, under Text Editor > C/C++ > General > Auto list members. If you invoke it a third time, an even wider list of program elements is shown. If you press Ctrl+ J after that, it shows all members regardless of accessibility. ![]() The first time that you invoke member list, it only shows members that are accessible for the current context. When you start typing a keyword, type, function, variable name, or other program element that the compiler recognizes, the editor offers to complete the word for you. You can use the menu items and keyboard shortcuts shown in the following image to access IntelliSense. The Options dialog box is available from the Tools menu on the menu bar. Since different people have different ideas about what is convenient, virtually all of the IntelliSense features can be enabled or disabled in the Options dialog box, under Text Editor > C/C++ > Advanced. IntelliSense is a name given to a set of features that make coding more convenient. For information on how to configure your project for IntelliSense and how to troubleshoot problems, see Configure a C++ project for IntelliSense. This article provides an overview of C++ IntelliSense features. c files in the shared code project, even when you are in an Android or iOS context. In cross-platform projects, some IntelliSense features are available in. IntelliSense for C++ is available for stand-alone files as well as for files that are part of a C++ project.
