Hi there, DirectX9 - ShadowMap Sample - rotating Objects Flicker In the case of two monitors system the revolving objects flicker excessively if the focus is changed from ShadowMap app(must not be in full screen mode) to another app on the other monitor. My question is why does this happen? I have customized the ShadowMap sample with larger objects in which case the flicker is noticable ...

I have inherited some code that displays a window that is rendered with directX9 - works fine on XP but in vista I just get a blank window. I am not getting any errors (i.e. the HRESULTS are always S_OK) on any of the directx calls. I do not know very much about directx and was wondering if anyone had seen something similar and could get me going in the right direct or has any pointers ...

Chris, That sounds like it should do the trick. But I am having problems with the exact syntax and commands to set the GlobalFocus flag for the buffer. Can you prompt me with the sequence of actual commads to set the buffer flags and create the buffer with the global focus?

I have what should be a simple problem but haven't been able to find a solution. I am using DirectX 9 to play a simple 16 bit mono sound file in a Sound card modem application. The playback code is simple: devSelectedPlaybackDevice.SetCooperativeLevel(Me.Handle, CooperativeLevel.Priority) bufPlayback = New SecondaryBuffer(Filename, devSelectedPlaybackDevice) ...

...would look like with out an effects file ? or is that not posible ? Thanks, k, go for identity matrices then, but DirectX9 and future is pretty much about effect files. your code would be something like -------------------------------- D3DXMATRIXA16 myMatrix; D3DXMatrixIdentity(&myMatrix); g_pd3dDevice->SetTransform( D3DTS_WORLD, &myMatrix ); g_pd3dDevice->...
