Disable RenderState | GameDev.net

So I have set things up so that whatever I draw adds up to whatever I draw behind it.

	app->d3d->d3d_device->SetRenderState(D3DRS_DESTBLEND,D3DBLEND_DESTALPHA);

Though I've been having trouble disabling it temporarily.
I've tried

	app->d3d->d3d_device->SetRenderState(D3DRS_DESTBLEND,FALSE);

and then setting it again but it doesn't get set again, it becomes disabled permanently.

I also tried D3DBLEND_ZERO and D3DBLEND_ONE but to no avail.

Any help is appreciated.

To disable alpha blending you need to set D3DRS_ALPHABLENDENABLE to FALSE. Setting D3DRS_DESTBLEND to FALSE (0) isn't valid, because there's no D3DBLEND type with the value 0.

Thanks! That did the charm. I was also forgetting to flush ^_^'.
