Qt Visual Studio Add-in 错误:未将对象引用设置到对象的实例?出现这样的提示是为什么

还有:
1>RCC xxx.qrc
1>'_' 不是内部或外部命令，也不是可运行的程序
1>或批处理文件。
1>Project : error PRJ0019: 某个工具从以下位置返回了错误代码: "RCC xxx.qrc"
这样的调试错误是为什么?

可能原因是你改变了编译环境导致,如重装了VS所致.

没人回答呀

qt for vs2008 插件, 很好用

这是用QT作的人事管理系统，里面是源代码，发给各位朋友参考参考，保证物有所值。注意：：这是在QT插入到Viual stdio 里才能运行出来的哟。

VS2010上用Qt4.8.2开发的画图板程序，把改程序放在全英文目录下，配置好环境即可运行。

这是我在window下在VS2010中使用Qt编程的时候进行开发配置的过程，

--------------------------- Qt Data Visualization 5.7.0 --------------------------- Qt Data Visualization module provides multiple graph types to visualize data in 3D space both with C++ and Qt Quick 2. System Requirements =================== - Qt 5.2.1 or newer - OpenGL 2.1 or newer (recommended) or OpenGL ES2 (reduced feature set) - Manipulating Qt Data Visualization graphs with QML Designer requires Qt Creator 3.3 or newer Building ======== Configure the project with qmake: qmake After running qmake, build the project with make: (Linux) make (Windows with MinGw) mingw32-make (Windows with Visual Studio) nmake (OS X) make The above generates the default makefiles for your configuration, which is typically the release build if you are using precompiled binary Qt distribution. To build both debug and release, or one specifically, use one of the following qmake lines instead. For debug builds: qmake CONFIG+=debug make or qmake CONFIG+=debug_and_release make debug For release builds: qmake CONFIG+=release make or qmake CONFIG+=debug_and_release make release For both builds (Windows/OS X only): qmake CONFIG+="debug_and_release build_all" make After building, install the module to your Qt directory: make install If you want to uninstall the module: make uninstall Building as a statically linked library ======================================= The same as above applies, you will just have to add static to the CONFIG: qmake CONFIG+=static Documentation ============= The documentation can be generated with: make docs The documentation is generated into the doc folder under the build folder. Both Qt Assistant (qtdatavisualization.qch) and in HTML format (qtdatavisualization subfolder) documentation is generated. Please refer to the generated documentation for more information: doc/qtdatavisualization/qtdatavisualization-index.html Known Issues ============ - Some platforms like Android and WinRT cannot handle multiple native windows properly, so only the Qt Quick 2 versions of graphs are available in practice for those platforms. - Shadows are not supported with OpenGL ES2 (including Angle builds in Windows). - Anti-aliasing doesn't work with OpenGL ES2 (including Angle builds in Windows). - QCustom3DVolume items are not supported with OpenGL ES2 (including Angle builds in Windows). - Surfaces with non-straight rows and columns do not always render properly. - Q3DLight class (and Light3D QML item) are currently not usable for anything. - Changing most of Q3DScene properties affecting subviewports currently has no effect. - Widget based examples layout incorrectly in iOS. - Reparenting a graph to an item in another QQuickWindow is not supported. - Android builds of QML applications importing QtDataVisualization also require "QT += datavisualization" in the pro file. This is because Qt Data Visualization QML plugin has a dependency to Qt Data Visualization C++ library, which Qt Creator doesn't automatically add to the deployment package. - Only OpenGL ES2 emulation is available for software renderer (that is, when using QCoreApplication::setAttribute(Qt::AA_UseSoftwareOpenGL))
