Re: Buttons Pop up [Part-2]

Hello,

If you are not familiar with the question of this post, you can get a
quick glimps at its description at the first part of this post called
"Buttons Pop up!"

The reason I started a new post on the same question is so I don't
clutter up the previous post! So here is a clean start!

I have taken the advice of a news groups fellow to strip down my
program so I can isolate the problem, and I did, however the
situation still persists. I call this a "situation" because at this
point, I don't know if the problem I am facing is normal when
creating a windows with CreateWindow();

In short, I now have two (2) windows, and therefore it means I have 2
WndProc's,
WndProc.cpp and WndProc_CW2.cpp which we will call Window#1 and
Window #2 respectively. I also have a Main.cpp for the good old
Windows message pump!

The first window is based on WndProc.cpp with one(1) button which
opens
a child window based on WndProc_CW2.pp. I also have an exit button on
the first window which is of no relevance to this issue.

So when I click on a button on window#1, it opens window#2, and do
you agree that some space on the second window is right above some
buttons of the first window right underneath.... right! (lets call
this space "space X"). So space
X is the space that is on my second window where it aligns directly
with the space containing a button on the opened window #1 which is
right behind it.

If I click on some of its space X, well, the button from the
underneath window, pops up in the top window(window #2) currently
open. ??? I can even move window#2 around and this newly poped up
button stays in the client area!

Does anyone have any I deas of what could be going on !

Here is a watered down skeleton of the app, it contains 6 very small
files!

Here's the code:

-Excuse me if its a long post....You would not believe how much code I
removed... however if you feel its still too long, its no problem,
let me know and I will repost a shorter version. Although, it only
looks long however its all basic routine code that is very common in
every Windows code.

Agian, excuse the lenghty post.....

So, basically, I always get the button to pop up from the bottom
window on to the top window when clicked on space X!

I am as we speak, trying to troubleshoot this, I surely appreciate
any input from the news groups!
