Brings up the Vector Camera dialog.

Parameters

HWND hWndParent

Handle of the window that owns the dialog.

pVECTORCAMERA pCamera

Pointer to a VECTORCAMERA structure that contains camera values. The values present in pCamera when the function is called are used to initialize the dialog. If this parameter is NULL when the function is called, the values used to initialize the dialog will come from the vector handle. When this function returns, this parameter is updated with the values entered through the dialog.
