Hi, all,<br><br>I posted my problem two days before and got no response. I have to express my problems more clearly. I hope you help me.<br><br>I use the VTK CVS nightly source of Oct. 7,2007 in my
applications. I built the VTK source successfully on Win XP using MSVC
2005. I set using CG Shader and GLSL shader be on during cmaking. My graphics card is GeForce 8300 and I updated the graphics
driver to be the latest. When I run VTK examples, there is no display window shown.
The error is as follows:
<br><br>Description: ERROR: In E:\Kitware\VTK\Rendering<div id="mb_0">\vtkWin32OpenGLRenderWindow.cxx, line 235<br>vtkWin32OpenGLRenderWindow (03A4C500): wglMakeCurrent failed in MakeCurrent(), error: The handle is invalid.
<br><br>When I build the VTK5.0 release sourcr and run its examples, everything is ok. It seems that it is because of the CVS nightly source problem. If not, could anyone show me any solutions? Many thanks!<br><br>James<br>
