Hi!

I am trying to access a function in oleacc.dll using
LoadLibrary and GetProcAddress, but for some reason it
doesn't work. 

Can someone point out the error?

The function I am going for (GetRoleText) should be a part
of the oleacc.dll on my machine (WinXP).

HINSTANCE MSAAhInst=NULL;

typedef UINT (APIENTRY *TGRT)(DWORD, LPTSTR, UINT);
TGRT pGetRoleText=NULL;

bool LoadMSAA() {
  if (!MSAAhInst) {
    MSAAhInst = ::LoadLibrary("OLEACC.DLL" );
    CoInitialize( NULL );
    if (MSAAhInst) {
      pGetRoleText=(TGRT)GetProcAddress(MSAAhInst, "GetRoleText");
    }
  }
  return (pGetRoleText!=NULL);
}
