Please help

Hello @Hani , and welcome.

We need more information to get a better idea.

  1. What version of Visual Studio are you using?
  2. What version of the OCX are you trying to compile?
  3. Are you trying to build 32-bit or 64-bit?
  4. The screenshot is only showing warnings, not errors encountered (unless you are compiling to treat warnings as errors?). Instead of a screenshot, could you copy/paste the text from the Output window?

Thank you.
Jerry.
