Normally, to load a new OCX, you select Custom Controls from the VB4 Tools menu. Then, in the Custom Controls dialog, click on the browse button, select the OCX file, and click on OK to install it. However, if the OCX does not run, it is probably missing the DLL files it needs. OCX controls created using VC++ 2.x need these files, which VB4 does not install: MFC30.DLL, MFCO30.DLL, and OC30.DLL. Make sure they're in your path and registered correctly. They should be supplied by the control. If the OCX was created using VC++ 4.0, the files MFC40.DLL and OLEPRO32.DLL already should be installed on your system by VB4.
