Hi,

Hi friends,

function. i m calling a function of this DLL.

So you have a dependency to that 3rd party dll and the loader needs to find
that dll when your dll is loaded

But i m getting error
error PRJ0050: Failed to register output. Please ensure you have the
appropriate permissions to modify the registry.

The registration step is the last step *after* your dll was successfully
built. Registration is done by loading your dll and calling the
DllRegisterServer function. When your dll is loaded from the output
directory the 3rd party dll will be needed. If it is not found, i.e. not in
the same directory as your dll, not in the current directory, not in
%windir%, not in %windir%\system32 not in the current directory, than your
dll cannot be loaded.

Try copying the 3rd party dll into the directory your dll is created in and
registration should work.

when i m commenting that function calling statement then no error
comes and it project compiles successfully.

It did compile (and link) successfully without commenting out that function.
Just look in the output directory and you will find the dll. By commenting
out all function calls to your 3rd party dll the linker is smart enough to
remove the dependency to the 3rd party dll, hence your can be loaded without
the other dll around.

I got tired of it...
