Header Item Rectangle

I am using VB.NET 2003
Framework 1.1

I can't get header item rectangle of ListView.

HeaderItemHandl e = SendMessage (HWnd, HDM_GETITEMRECT , i,
headerItemRecta ngle)

Problem is in declaration of SendMessage API (lParam can't be of type RECT):

Private Declare Function SendMessage Lib "user32" _
(ByVal hWnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal
lParam As Integer) As IntPtr

How could I get headerItemRecta ngle?
Please, would you like to post an example?

Thanks all!

\\\
Public Structure RECT
Public left As Int32
Public top As Int32
Public right As Int32
Public bottom As Int32
End Structure
///

Declare the last param of 'SendMessage' as 'ByRef lParam As RECT'.

Hi all; Putting "Due" into the column header of a datagrid. Font is a proportional fort. When the alignment is left, there is some space between the column separator bar and the D in Due. When the alignment is center, Due is centered in the header box. When the alignment is right, the e in Due is partially covered by the column separator bar. Adding space after Due (i.e.. "Due ") does not work. HeaderText seems to be trimmed before...

Is it possible to selectivly change the color of an item in text. I saw ForeColor option, but it changes the color of all the items. If it is not possible, is there any other control list listbox where we can see more than one item and change the color during run time. Thanks.
