How add tool to toolbox using arcrngine in C#? All times that i tried to do this, i add tool only once. I create class library project, add some code as BaseTool, build, it's generate dll file. Then i try to add this dll using desing properties of ToolBox, but get error "An error occured when try to add command". In that one success time, when i add tool, project also generate tlb file. How it generate i can't understand. Maybe in this is problem?
Thanks for any advices.
Roman.
