Hi :) I have a problem with a primary device and alt tab ? when a made a ALT TAB the program crash at this line "PrimaryDevice.device.DrawPrimitive(RenderType,D...." Is there a way to stop the rendering/freeze rendering to prevent ALT TAB crash ? |
| ||
I have try to find DX doc about this and there is a command DeviceLost But i don't know how use it ? |
| ||
Try checking this variable.. TD3D7Max2DDriver(_max2dDriver).IsLost before attempting to play with the PrimaryDevice Doug Stastny |

Many thanks budman !!! it work ! Here is the code |

Great glad to have helped. Comment on your code. DrawPrimative must be between BeginScene, EndScene. The 2d driver manages the Scene State so you shouldnt need EndScene.. BeginScene. I am suprised it works. Some cards might not though. If TD3D7Max2DDriver(_max2dDriver).IsLost=False TD3D7Max2DDriver(_max2dDriver).SetActiveFrame(DXFrame) ' not needed PrimaryDevice.Device.EndScene() PrimaryDevice.device.DrawPrimitive(RenderType,D3DFVF_XYZ|D3DFVF_NORMAL|D3DFVF_DIFFUSE|D3DFVF_TEX1,xyuv,segs,0) ' not needed PrimaryDevice.Device.BeginScene() EndIf Doug Stastny |
