Embedding directx app with C++ Builder dll

I want to add some functio开发者_JS百科nality to another directx application(game). I am creating new thread in DllMain, in thread i create my TForm1 and use its method ShowModal(). And it works! But the problem is - the interface of my app looks like Win95(flat) style. Any ways to solve it? I think i need to set some WINAPI settings, before creating my form.

Try to either add the TXPManifest to your form (from the Win32 Tool palette) or go to the project options and set "Enable runtime themes" under Application.
