Linker Error - GradientFill

I keep getting the following error

[Linker Error] Unresolved external 'GradientFill' referenced from 
C:\PROGRAM FILES\BORLAND\CBUILDER5\PROJECTS\...\FRMMAIN.OBJ

But code insight shows the prototype/parameters

it is declared in Windows.hpp
function GradientFill; external msimg32 name 'GradientFill';

  & wingdi.h
WINGDIAPI BOOL  WINAPI GradientFill( IN HDC, IN PTRIVERTEX, IN ULONG, IN 
PVOID, IN ULONG, IN ULONG);


Anybody get this to work? Can think of what I might be doing wrong? Know 
the phase of the moon? :)

Any help would be greatly appreciated. Code follows:

//---------------------------------------------------------------------------
void __fastcall TMainForm::FormPaint(TObject *Sender)
{
    int startColor = ColorToRGB(clBlue);
    int endColor   = ColorToRGB(clBlack);
    TRIVERTEX      vert[2];
    GRADIENT_RECT  gRect;

    vert[0].x      = 0;
    vert[0].y      = 0;
    vert[0].Red    = GetRValue(startColor);
    vert[0].Green  = GetGValue(startColor);
    vert[0].Blue   = GetBValue(startColor);
    vert[0].Alpha  = 0x0000;

    vert[1].x      = 0;
    vert[1].y      = 0;
    vert[1].Red    = GetRValue(endColor);
    vert[1].Green  = GetGValue(endColor);
    vert[1].Blue   = GetBValue(endColor);
    vert[1].Alpha  = 0x0000;

    gRect.UpperLeft  = 0;
    gRect.LowerRight = 1;
    GradientFill(pnlEventEditor->Handle,
                 vert, 2,
                 &gRect, 1,
                 GRADIENT_FILL_RECT_H
                );
} //End FormPaint()
//---------------------------------------------------------------------------

Please do not cross-post.  It is against Borland's newsgroup
guidelines (http://info.borland.com/newsgroups).  Only post to the
single most appropriate group.  Your question has been answered in the
.graphics newsgroup (which was not the appropriate group, either).

I suspect that Gambit asked you not to cross-post in this
thread because by time he saw it, he had already answered
your post in the student group.

To be clear, this is the best group for that question but the
student group is also acceptable.

This group is for questions related to use of the Win32 API.  His
question was in regards to a linker error instead.  Linker-related
questions belong in the .ide group instead.
