<DIV><FONT face=Arial size=2>Thanks for that Kyley. I managed to implement
AllocateHWnd etc, and everything appears correct and logical. It's picking
up some Windows messages but not the WM_USER messages being sent. WM_USER
is message number 1024. I'm getting Message.Msg = 28 and that's about
it.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I tried the same code in the mainform as a
test and this worked but only after I specified the following:</FONT></DIV>
<DIV><FONT face=Arial size=2>
<DIV><FONT face=Arial size=2>procedure MyMessage(var Message: TMessage); message
WM_USER;</FONT></DIV>
<DIV> </DIV></FONT></DIV>
<DIV><FONT face=Arial size=2>If I leave off "message WM_USER", then nothing gets
through to the procedure in the mainform at all.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I tried this in the unit and it doesn't make any
difference. Message 28 is still getting to the procedure and no
1024.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>You can tell I'm no expert when it comes to
this. Do I need to use your fancy looking wrapper class?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I must be missing something.</FONT></DIV>

<DIV><FONT face=Arial size=2>I'm writing a component which communicates with
a 3rd party DLL using WM_USER messages. After loading the DLL,
I need to tell the DLL the handle to send user messages back to,
so my unit can intercept them, but I don't know where to get a handle
from. I know how to do it in the mainform of a program but not in a
separate unit. The messages sent to the mainform do not appear to
reach my unit.</FONT></DIV>

<DIV><FONT face=Arial size=2>What do I need to do to make this
