What are OCX files


Do you have Microsoft Windows XP loaded in your computer? Then you will certainly find a number of files in the Windows folder that end with the extension .ocx. These files are special types of program files, which allow the operating system to let the user perform certain functions, such as resize an open window, or to define how the scroll bars will work in a program custom-made by the user. The use of OCX files in a program will substantially increase its stability and overall quality.

OCX files are not just system files that enable certain functions in the operating systems. These are also bundled with software development tools and SDKs to help software developers introduce extra functionalities into their software programs. For instance, a developer may add support for displaying more than 65 million colors to his program coded using VB.Net by incorporating a small OCX file in the program package. They may also improve the internet connectivity of their programs using an OCX file.

If you buy a software utility, then usually the associated OCX files will come bundled with the software itself. When you install the software, the OCX files will be automatically installed with it and registered in the Windows registry. You can, however, manually register OCX files to the Windows registry, if you suspect that those have not been registered properly. Here’s how:

  1. Locate the file in your PC. If you know where it is, fine. Otherwise, use the Windows Search to locate it.
  2. Right click on the file, while holding down the Shift key on your keyboard.
  3. Choose the option “Open With” from the pop up menu.
  4. Click on the option “Select the Program from a list” in the next window and click OK.
  5. In the next window, click on Browse.
  6. Navigate to the Windows folder and then to the System32 folder inside it.
  7. Locate the file RegSvr32.exe and select it.
  8. Click Ok.
  9. You should see a confirmation message saying that the OCX file was successfully registered.
  10. If you see and error message, then restart your PC and try the process again.

If you fail to register the OCX file even after repeated attempts, then there is a chance that the file may be corrupted. You should try to download a fresh copy of the file by searching on the internet.
