// Unlucky... I uninstalled vs2003 and changed it to vs2005. Asp.net will not work properly. A registered com cannot be found. This COM is also self-written and compiled with vs2003. The com registration information in the Registry is also correct where the file is clearly located, and he says he cannot find it. Dizzy... Later, I used dependecy to read the DLL file of the COM component .. Mfc71d. dll and msvcr71.dll cannot be found .. Originally, it was compiled using vs2003 to dynamically connect to MFC... Uninstalled vs2003... The MFC Library of vs2003 is also gone .. Therefore, if the COM component cannot find the DLL file, an error is returned... But this error cannot be clarified ?? Find the DLL directory where the two files are copied to com. OK! Done.
