• Game Technologies: DirectX, XNA, XACT, etc. Floating point strikes back

  I'm starting to realy hate this floating point hell. I have another problem with floats, and this time I can't see the solution. I have a simple mesh (just a square with two faces with size 100). The vertice list in the x file is as follows: -50.000000;0.000000;-50.000000; 50.000000;0.000000;-50.000000; -50.000000;0.000000;50.000000; 50.000000;0.000000;50.000000; Now, when I access the vertice buffer after loading the mesh, the values are not t ...Show All

• Windows Forms Automatic toolbox item service ignores ToolboxItem attribute

  The service that automatically creates toolbox items is not using the correct class: it ignores the ToolboxItemAttribute on the component that specifies which ToolboxItem-derived class to use, and instead creates a ToolboxManagerToolboxItem. The result is a bunch of unusable Toolbox items. We have already logic to populate the toolbox with a correct ToolboxItem whenever the designed class is opened in our graphical root designer. So we h ...Show All
