====== which dll is loaded? ======
It is often helpful to know which dll file your exe has loaded at runtime.  If you uncomment the first HINSTANCE line, you can specify which path to load a dll, or allow the OS to find one for you.

<code cpp>
// explicitly load dbExpress driver
// HINSTANCE hinstLib = LoadLibrary(TEXT("C:\path\to\specific\location\somefile.dll"));

HINSTANCE hinstLib = LoadLibrary(TEXT("somefile.dll"));
if (hinstLib == NULL) {
    ShowMessage("ERROR: unable to load DLL\n");
    return 1;
}

// find the path/filename of the loaded driver
LPTSTR  strDLLPath1 = new TCHAR[_MAX_PATH];
if( GetModuleFileName((HINSTANCE)hinstLib, strDLLPath1, _MAX_PATH) ){
    ShowMessage(String(strDLLPath1));
}
