How to register an ActiveX control (.ocx) manually

MORE INFORMATION

You can use the Microsoft Register Server (Regsvr32.exe) to register a 32- bit .ocx file manually on a 32-bit operating system. In Visual FoxPro 3.0 and 3.0b, Regsvr32.exe is located in the \Vfp\Samples\Ole directory, and in Visual FoxPro 5.0, Regsvr32.exe is located in the \Vfp directory. In Visual FoxPro 6.0, Regsvr32.exe is found in the Distrib.src directory of the Visual FoxPro directory. It may be distributed with a Visual FoxPro application. The syntax for using Regsvr32.exe is as follows:

   Regsvr32 [/u] [/s] <OCX File Name>
					

Note /u means Unregister the .ocx file.
/s means Silent Mode (display no messages).

The following example registers the Microsoft MAPI ActiveX Control without displaying any messages:

   Regsvr32 /s MSMAPI32.OCX
				

To implement this example in a Visual FoxPro application, use the RUN command as follows:

   RUN /N Regsvr32 /s MSMAPI32.OCX
				

Note If an error occurs when registering a control, do the following:

1. Verify in the Registry that the control has not been registered before.
2. Verify that the following files are in the Windows\System directory:

         mfc30.dll     olepro32.dll     msvcrt20.dll
         mfc40.dll     msvcrt40.dll

   If one of these files is missing, you may receive the following error message:
   Error: OLE Error Code 0x80040112: Appropriate license for this class not found.
