Hi guys,
D3D Device failure during screen lock and also failure during UAC. it's not a big problem for game engine but i made a desktop program with acknex. it's running always. so if i run any setup program, my application crashes by uac. if i locked the windows screen, it's crashes again.
Want to share two videos about problem: crash after screen lockcrash by uac it crashes randomly especially if project contain a view.stage. My opinion is the problem is related with render target. Just guessing, still not sure.
i wonder is there anything i can do. i really need to solve this problem. is there any way? Please share your idea and information with me.
Here is the test code which i use in first video:
#include <acknex.h>
#include <default.c>
MATERIAL* test_mat1 =
{
effect="Texture TargetMap;
sampler2D g_samSrcColor = sampler_state { texture = <TargetMap>; MipFilter = Linear; };
float4 postprocessing_negative( float2 Tex : TEXCOORD0 ) : COLOR0
{
float3 Color = 1. - tex2D( g_samSrcColor, Tex.xy).xyz;
return float4(Color,1.);
}
technique PostProcess
{
pass p1
{
AlphaBlendEnable = false;
VertexShader = null;
PixelShader = compile ps_2_0 postprocessing_negative();
}
}";
}
VIEW* post_view1 ={layer = 0; flags = PROCESS_TARGET; material=test_mat1;}
function d3dreset()
{
diag("\n\nD3D DEVICE RESET!\n");
}
function d3dlost()
{
diag("\n\nD3D DEVICE LOST!\n");
}
function main()
{
on_d3d_reset=d3dreset;
on_d3d_lost=d3dlost;
wait(3);
level_load("");
camera.stage = post_view1;
}
You can test it. i have A7. if you have A8 you will probably get different message like: "
3D Hardware Reset Failure."
