compile error with shlobj.h

[inetd]

When I include the shlobj.h in my cpp file, there is always a compile error with:
"Multiple declaration for FVSHOWINFO"
"Earlier declaration for FVSHOWINFO"
"Multiple declaration for FOLDERSETTINGS"
"Earlier declaration for FOLDERSETTINGS"
....
....
....

What does it mean? How can fix it?
I have not written any code in the unit but it also generate the above error if including the shlobj.h.

I am using Borland C++ Builder 5 Professional Edition.

Anyone can give me a hint?

Thanks.

FVSHOWINFO and FOLDERSETTINGS are varibles that are declared multiple times. For example,

bool FVSHOWINFO;
string FOLDERSETTINGS;
.
.
.
for (int j = 0; j < ANumber; j++)
{
    bool FVSHOWINFO; // Error
    string FOLDERSETTINGS; // Error
}

You will have to look carefully in the header file for the declartions for these varables.

I think it is because you should not include this file directly. You should use some other .h which includes this one.

I don't know what caused this problem but if you want to avoid it you must add at beginning of cpp file this:

#define NO_WIN32_LEAN_AND_MEAN

I'm sure it will work.

Thanks domainochmiel,

After I post the question, I have found a example that also uses shlobj.h and it has mentioned that:

#define NO_WIN32_LEAN_AND_MEAN

should be in the first line of the cpp unit file.

I have tried it and it works.

Anyway, thanks to everybody.
