thank a lot
i understand my error, xlwDotNet wasn't installed because i left it grayed when it was installed
i swichted to xlw 4 and Visual C#2008 because i prefer these version more completed
i followed the video on youtube "howto create a C# XLL addin using XLW&Visual Studio"
everything goes well until i want to build my solution, i have this error:
" MSB3073 : La commande ""C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\..\..\VC\vcpackages\vcbuild" "C:\Users\Julien\Documents\XLL_Project\Addin\DemoXLL.sln" "Debug|Win32"" s'est arrêtée avec le code 9009. "
i was so close to success , once again your precious help would be welcome
Which version of Visual Studio do you have installed ? Express or PRO ?
Do you have Visual Studio C++ installed ? Because it is required and if you do not you will need to install it and it should work.
