[MDX] Initializing in a picture box
Author
How can you initialize the directx viewport in a picture box? Rather than the entire window?
Don't use a picture box, use a panel. All you have to do is pass the panel when creating the device instead of the form.
Device = new Direct3D.Device(
0,
DeviceType,
Control, // <- here
CreateFlags,
PresentParameters );
Device = new Direct3D.Device(
0,
DeviceType,
Control, // <- here
CreateFlags,
PresentParameters );

I get an error initializing the device. I have tried this:
new Device(0, DeviceType.Hardware, panel1, CreateFlags.SoftwareVertexProcessing, presentParams);
and this:
new Device(0, DeviceType.Hardware, this.panel1, CreateFlags.SoftwareVertexProcessing, presentParams);
The device just will not create. What is wrong?
new Device(0, DeviceType.Hardware, panel1, CreateFlags.SoftwareVertexProcessing, presentParams);
and this:
new Device(0, DeviceType.Hardware, this.panel1, CreateFlags.SoftwareVertexProcessing, presentParams);

Ok. Thats better and it doesn't fail in initializing but i get this debug error:
An unhandled exception of type 'System.NullReferenceException' occurred in Demon Heart Construction Set.exe
Additional information: Object reference not set to an instance of an object.
Thanks for all of the help.

The error tells you your trying to use an object that is null. This means you have an object that has not been instanciated (ObjectClass object = new ObjectClass()).
You should be running your application in debug mode so when you run it, it will show you the line the error is occuring. Once you know the line you will see the object your trying to use has not been instanciated.

Okay. Its the panel that is giving the error.
I'm not completely sure what you mean but i tried this and it didn't fix it:
this.panel1 = new Panel();
it just gave the same error. I am doing this with the form design thing if that makes a difference.

If your using the form designer to draw the panel on your form, you don't need to manually instanciate it. It will do that for you.
I suspect the the form hasn't been drawn yet before your trying to access the panel. Try placing a this.Show() before you create the device.

Its still not working. This is the code I am using now:
Thanks for your help!
