I have decided to add this structure, since no one bothered

Private Type GuiTable
dwStructSize As Long
uuidObjectGUI As UUID ' // 0x04 UUID of Object GUI
uuidFreezeEvent As UUID ' // 0x08 Compared with UUID of "IID_IFreezeEvents"
lObjectID As Long ' // 0x24 Current Object ID in the Project
fControlFlags As Long ' // 0x28 Changes depending on which Controls the Object Implements
fOLEMisc As Long ' // 0x2C OLEMisc Flags
uuidObject As UUID ' // 0x30 UUID of Object
dwReserved As Long ' // 0x40 Unused.
dwObjectInfoSize As Long ' // 0x44 Size of Object GUI Data

End Type

I'm too tired to update the PDF for now..but here you go _aLfa_

Forgot to add, I'm 99% sure the fControlFlags are the same as the MDL flags, but I will have to check it out. Basicaally, depending on which controls I added, new bitmasks where added..you can try it out, but i'll have a defintiive list tomorrow. I'm also positive that uuidFreezeEvent is also compared to other UUIDs... anyways, its some kinda secondary UUID. you're pretty good with those, so you might try finding out...I've never seen it in a compiled project of mine, but the runtime defintely reads and compares it with IID_IFreezeEvents. I don't know what would add it yet...

and dwReserved is unread/unwritten by the compiler, at least that's what 1 hour of research came up with.
