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. ---
