CBT_CREATEWND Structure

[xroot]

Hi,
How would you convert the following C++ code to MASM and any vars,defs needed, not having any luck, thanks for any help.

          LPCBT_CREATEWND lpCbtCreate = (LPCBT_CREATEWND)lParam;
          if(WC_DIALOG == lpCbtCreate->lpcs->lpszClass)

The CBT_CREATEWND structure contains information passed to a WH_CBT hook procedure.
HCBT_CREATEWND set wParam and lParam as follows.
wParam=Specifies the handle to the new window.
lParam=Specifies a long pointer to a CBT_CREATEWND structure containing initialization parameters for the window.
The parameters include the coordinates and dimensions of the window. By changing these parameters,
a CBTProc hook procedure can set the initial size and position of the window.
