I have a VB project was able to work without any issues, but now when i open the project i am getting the error with mscomctl.ocx. I have re-registered the ocx but still am not
it seems to me your project has lost its reference to the ocx (while it still tries to use some of the controls)
click on 'components' in the 'project' menu in the ide
in the list make sure 'microsoft windows common controls 6.0 (sp6)' is checked ... if it already is, try removing it, close (and save) the project, open the project, and turn it on again
