Reg SetFuncAndParamNames Errors

[Ravi Kumar]

Hello Codegurus,

I have a problem while building my Component DLL. I got an error whose discription is as following:

midl\oleaut32.dll : error MIDL2020 : error generating type library : SetFuncAndParamNames failed : get_FA_NUMBER

I do not understand what could be the possible cause for this error. MIDL2020 error in MSDN online says that the possible
cause for this error is specifying a path to the IDL file that is longer than 126 characters, but this is not the case with me.

Can you please throw some light on this.

Thanking you in advance.

Regards,
Ravi

This is an old thread, but in researching this error earlier in the week, I found that it's among the first results returned by Bing for the MIDL2020 keyword. Thus, I'd like to update it with my finding that assigning different [id(X)] attributes to the getter and setter of the same property will cause this error.
