I have created a deskband followed by the tutorial on codeproject (http://www.codeproject.com/KB/shell/dotnetbandobjects.aspx).
After I installed the deskband, I realized there is something need to be modified. So I I uninstalled the deskband, went back to my code and edit the code, rebuild the solution, re-install the deskband. However, in the taskbar, the deskband shows as nothing was changed, the modification does not make any change. Anyone knows why is that?
