[vtkusers] help!!!about vtkMDI

[zhao yong qiang]

Hi all,
I meet such a strange question.
I install vtk. My environment is VTK＋MSVC+WIN2000.
Then I follow the example of vtkMDI,
But in vtkOutputWindow.it showes:
 
ERROR: In C:\martink\vtk42\VTK\Rendering\vtkWin32OpenGLRenderWindow.cxx,
line 734
vtkWin32OpenGLRenderWindow (0x0148E248): wglCreateContext failed in
CreateAWindow(), error: 1114

ERROR: In C:\martink\vtk42\VTK\Rendering\vtkWin32OpenGLRenderWindow.cxx,

but in disk C, there is not such directory.
Can someone help me? And tell me how to solve it?　
Why VTK does not call lib file, but call vtkWin32OpenGLRenderWindow.cxx?
Thanks!!!!
