I recently installed ArcGIS 9.3 in a PC with Windows 7.0. I opened an existing mxd file within which I developed some toolbars for a project. Each icon of a toolbar has behind it a VBA and ArcObjects code. Unfortunately, I noticed that icons are all missing and the symbol of each icon has been replaced by a red circle with a slahed line and the commnad of Visual basic editor under the Tools menu is always disabled-inactive, thus I cannot get in the VBA editor.
Can anybody help me please?
