<FONT color=#000000 size=2> I code a stereo test program using VC2008. The following is my code.</FONT><BR>

<FONT size=2> The above code can render 3D image for Crystal eyes correctly. </FONT><BR>
<FONT size=2> However, when i use the same code on Borland C++ Builder, the stereo mode don't work.</FONT><BR>
<FONT size=2> I use ComboBox to select the stereo mode dynamically.</FONT><BR>
<FONT size=2> The effect work well except the crystal eyes.</FONT><BR>
<FONT size=2> This is my event code for ComboBox.</FONT><BR>
