ActiveX control cannot be registered during VB engineering.

ActiveX control cannot be registered during VB engineering.

You must have encountered this problem when working on the VB project. When adding controls to VB, project → parts → browsing. After adding components you need, "*. ocx cannot be registered as ActiveX control. At this time, you may register it with regsvr32, But it prompts "*. loading ocx control failed. No matter whether you put it in system32 or system64 (Win7 64-bit), whether you register it as an administrator or not, the result ...... . It is likely that your system lacks the DLL dynamic link library on which the OCX control depends.

Someone asked, How can I know what DLL files my OCX control depends on? We recommend that you use the Dependency Walker tool.

When you use Dependency Walker to open the OCX control (taking AVPhone3.ocx as an example), for example:

For example, the following MSACM32.DLL, MSVFW32.DLL, and so on are the DLL files it depends on. Which DLL file is missing in your system will turn yellow and there will be a question mark. If so, download the corresponding DLL file and register it. Then, try registering your OCX control. Is it successful!
