Everything stops rendering when resizing or changing resolution

[Jadd]

So, I can render everything just fine, but whenever I resize the window, or change the resolution, everything just stops rendering. For example (using CS:S in this example because it's already open but I've always had the same issue with WoW):

1360x768:

1280x720


I've tried setting an event handler to things like Device.DeviceReset and Device.DeviceResizing but neither seem to even get called. I've also tried some hackish ways of getting around it, like

if (internalViewport.Width != Globals.Device.Viewport.Width ||
    internalViewport.Height != Globals.Device.Viewport.Height)
{
    internalViewport = Globals.Device.Viewport;
}
else
{
    EndScene.Pulse(); //Render everything
}

But unfortunately the viewport gets changed after the resizing is done (seems weird to me, but apparently that's the way it works), so it still tries to render everything. I'm pretty sure that this is what's breaking everything. I'm wondering if there are any ways to get around this problem. Any hackish solutions would also be appreciated.

Thanks.

The supposed "normal" way of things (not hooked) with respect to resizing is to release all your acquired resources at that point, call the Reset() function on the device, then recreate when needed afterwards.
Calls to SetCooperativeLevel and whatnot should also be used to determine when and where - the documentation on MSDN is sufficient for figuring out when to handle Reset and the like.

Hooking Reset() and doing the same procedure in a hack should be fine - I use that procedure with my code and it works a treat.

Yup. Hook IDirect3DDevice9::Reset for profit.

But shouldn't the EventHandler "Device.DeviceReset" do that all for me? For example:

public static int EndSceneHook(IntPtr instance)
{
    Globals.Device = new Device(instance);
    Globals.Device.DeviceReset += DeviceReset;

    return (int) Globals.Magic.Detours["EndScene"].CallOriginal(instance);
}

static void DeviceReset(object sender, EventArgs e)
{
    MessageBox.Show("0");
}

... I don't understand why this doesn't work

Assuming DeviceReset belongs to a managed wrapper of DirectX and is no intrinsic (unmanaged) functionality, it will only be fired if you call Reset through the managed layer.
If you insist on using that event, you can hook IDirect3DDevice9::Reset and call the Reset of your managed wrapper from there (firing the DeviceReset event). Don't forget to remove the hook before calling Reset though.

Thanks, this actually made a lot of sense. +Rep to all of you

Wouldn't recommend this as it isn't thread-safe in the case of multiple devices. Better to just call back into your code directly from the hook, then call the original using a trampoline as normal.

That reptile sounds reasonable.
