SUMMARY

When you distribute a Microsoft Visual FoxPro application that uses an ActiveX control (.ocx file), the .ocx file must be registered correctly for it to work correctly. The Visual FoxPro Setup Wizard or InstallShield Express in Visual FoxPro 7.0 or a later version of Visual FoxPro will register an .ocx file correctly, provided that you select the OLE check box in Step 6 for the .ocx file. If a Visual FoxPro application that uses an .ocx file is distributed by some other method, the .ocx file must be registered manually. This article describes how to register an .ocx file 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.
