I am trying to send a left mouse click to a certain position within a child window. I have the handle of the child window, but cannot get the sendmessage to work. Any ideas?

Here is some of the code:

[code]

Type POINT_TYPE
x As Long
y As Long
End Type

Public Function MAKEWORD(ByVal bLow As Byte, ByVal bHigh As Byte) As Integer
MAKEWORD = Val("&H" & Right("00" & Hex(bHigh), 2) & Right("00" & Hex(bLow), 2))
End Function

'--------------------------------------------------------------------

strWindowTitle = "Find"

AppActivate (strWindowTitle)

Call HPause(0.5)

lHwnd = FindWindow(vbNullString, strWindowTitle)

lCwnd = FindWindowEx(lHwnd, 0&, ThunderRT6ListBox", vbNullString)
lCwnd2 = FindWindowEx(lHwnd, lCwnd, "ThunderRT6ListBox", vbNullString)

packed = MAKEWORD(112, 73)

rc = PostMessage(lCwnd2, WM_LBUTTONDOWN, MK_LBUTTON, ByVal packed)
DumEvents = DoEvents
DumEvents = DoEvents
rc = PostMessage(lCwnd2, WM_LBUTTONUP, MK_LBUTTON, ByVal packed)
