i have added a new tool to the toolbox in visual studio by adding an existing solution to my solution and automatically a new tool was added to the toolbox.

now, how can i make it portable so that when i open my solution on another pc, it will be available?? since when i opened my solution on another pc, i had a warning that the file was not found and that the solution is unavailable..

thanks in advance

You'll have to copy the DLL that your tool project created to the new machine.

i don't have a dll, since i only inserted an existing solution (which includes the ribbon and checkboxcomboBox tool) to my solution

Did you add it as a project to your solution or did you copy the files into your solution. IF the former, there is a DLL there.

i added the solution to my project !
