Using MyGUI in a directx hook but its not rendering anything

I am trying to use MyGUI for a directx 9 hook that I created. I basically inject my code into another application. I would like to use this to create a chat screen kind of situation but unfortunately I can't get it to work quite yet. I am able to compile and get MyGUI and everything setup properly so that it builds and I can create a button widget (testing) that will load. The problem is that I can't get anything to render or show up. I am using the setupResources method straight from the demos.

The interesting thing is that I can use pIDirect3DDevice9 and do all sorts of directx drawing on my own with no issues. I assume I could pass this to MyGUI and let it draw as well. The only thing I can think of is that I am missing some other rendering code. I am calling mPlatform->getRenderManagerPtr()->drawOneFrame(); on every frame.

One thing to keep in mind is that the game already creates all the DX init code as well as draw its own stuff. I then hook into endscene() or even present() and do my own drawing which is where MyGUI is coming in.

Thanks!

My basic initialization code is

static MyGUI::Gui* mGUI;
static MyGUI::DirectXPlatform* mPlatform;

mPlatform = new MyGUI::DirectXPlatform();
mPlatform->initialise(pIDirect3DDevice9);

setupResources();

mGUI = new MyGUI::Gui();
mGUI->initialise();

MyGUI::ButtonPtr button = mGUI->createWidget<MyGUI::Button>("Button", 100, 100, 300, 26, MyGUI::Align::Default, "Main");
button->setCaption("exit");

This is my log... If its useful.

look at BaseManager for DirectX Platform.

1. mPlatform->getRenderManagerPtr()->setViewSize(width, height);
2. mPlatform->getDataManagerPtr()->addResourceLocation(_name, _recursive);
3. mPlatform->getRenderManagerPtr()->drawOneFrame();

I have called all of those methods. Do they all need to be called every frame? I call the addResourceLocation to load the resources and that seems to be working. I then tried the setViewSize method but I believe I only called it once in the initialization code. Not seeing any button my screen.

My initialization code:

mPlatform = new MyGUI::DirectXPlatform();
mPlatform->initialise(pIDirect3DDevice9);

RECT rect = { 0, 0, 0, 0 };
GetClientRect(xenHwnd, &rect);
int width = rect.right - rect.left;
int height = rect.bottom - rect.top;

//resizeRender(width, height);

if (mPlatform)
mPlatform->getRenderManagerPtr()->setViewSize(width, height);

setupResources();

mGUI = new MyGUI::Gui();
mGUI->initialise();

MyGUI::ButtonPtr button = mGUI->createWidget<MyGUI::Button>("Button", 100, 100, 300, 26, MyGUI::Align::Default, "Main");
button->setCaption("exit");


You should call mPlatform->getRenderManagerPtr()->drawOneFrame(); every frame.

I am doing that. I also tried setting the view every frame. I am not quite sure how your DirectX render works I guess. The important thing in how my code must work is that the game will draw first and I cant get around that. I then draw my stuff just by calling the draw stuff methods in directx. I assumed once I passed MyGUI my device it would draw to it just the way I do. The only thing I can guess is that MyGUI draws to a wierd viewport or something and not the one I am drawing too.
