今天遇到一个怪事, MFC的toolbox是灰的, 不能使用, 后来上网一查找到解决方案:
右键Toolbox, 点击"Choose Items", 重新启动VS2013, 这样toolbox就可以使用了
还有一些解决方案:
1) Closed all instances of VS, went to: C:\Users\Casey\AppData\Local\Microsoft\VisualStudio\10.0, and deleted thesde files:
toolbox.tbd
toolbox_reset.tbd
toolboxIndex.tbd
toolboxIndex_reset.tbd
2) In VS command promt: devenv.exe/resetsettings
3) In VS: Tools > Choose toolbox Items > .NET Framework Components > Reset
4) In the toolbox tab, right clicked and selected "Reset Toolbox"
5) In the toolbox tab, right clicked and selected "Show All". This shows a long list of tool options, but in every case they are greyed out and not usable.
5) Rebooted
6) Cast a few well chosen hexes and spells at Microsoft
