How to create – add C++ Windows Form Application in Visual Studio 2012
Step One
Download the following files.
VS 2012 CPP Win Forms.zip
http://www.abouthack.com/images/articles/programming/c-plus-plus/windows-forms-application-in-visual-c-2012/VS2012CPPWinForms.zip
Now extract the compressed file.
Step Two
Now fire up windows explorer and go to “C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\vcprojects\vcNET\“
or “[Visual Studio Installation Directory] \VC\vcprojects\vcNET\“
Step Three
Create a new directory and now backup all the files.
Step Four
Now copy all the extracted files from “Step One” and paste inside this folder “C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\vcprojects\vcNET\” or “[Visual Studio Installation Directory] \VC\vcprojects\vcNET\“
For all you VS express users:
use this directory: C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\vcprojects_WDExpress\vcNET\
and you also need to copy the WinForm directory from another version to C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\VCWizards\AppWiz\.NET\
Here’s the path for Winform in Visual Studio Express 2010:
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\VCWizards\AppWiz\.NET\WinForm
Here’s the path for Winform in Visual Studio Express 2012:
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\VCWizards\AppWiz\.NET\WinForm
Step Five
Run Visual Studio and select New Project > Visual C++ > CLR
Now you should be able to see Windows Forms Application
Be aware that the resulting C++ WinForm application in VS 2012 will use .Net Framework 4.5.
Step Six (optional)
Create a new Windows Forms in Visual C++ and see if everything is working or not.
