You had posted this yesterday I believe. I had given the solution too, Did that not work or is that you did not know how to do it? If so please let us know. We can explain you in steps how to do that.

Hi!
I have a strange problem: I want to pop-up a (modal) dialog from an ActiveX control which is a MDI child. I created the dialog and it pops up as regularly using DoModal. I can click around and use the dialog until I don't click the title bar e.g. in order to drag the dialog around. If I do so the dialog freezes the mouse input and I can only navigate through the dialog via keyboard.
Using Spy++ I checked the message queue. When I click on the title bar a WM_SYSCOMMAND (WPARAM: SC_MOVE) is sent and that's it. Message queue hangs. All I can do is navigating by keyboard or Alt+Tab away from and back to the dialog. Then I can use the mouse again. Surely without clicking on the title bar.
I googled for the problem and saw that some people have the same problem but there is no real solution for it. Somebody proposed to surround DoModal with PreModalDialog/PostModalDialog which didn't change anything.
Is it possible that some ActiveX events are missing that need to be routed to the control? I'm out of ideas anyway... 
Thanks for your help.

alright, found a solution:
problem was that MSDN Q187988[^] was applied sometime before which swallowed all my precious messages using a Windows WH_GETMESSAGE hook.
my quick and dirty solution is to disable the windows hook directly before opening the popup dialog and enable the hook again directly after the popup dialog is closed. everything works fine then and I can finally drag the dialog around... yipeeh! what a pain in the ...! 
perhaps there is a smarter solution. if you know one I would be glad for a short post.

Check the properties of your CListCtrl if Auto arrange, Sort, etc is on. Uncheck whichever is unnecessary and see if that helps. I cannot think of any other reason which could cause this problem.

I am trying to update a program written in C++ using VS6 to VS.NET 2003. One of the errors I can´t solve is the following:
the code:
template <class t="">
class _NoAddRefReleaseOnCComPtr : public T
{
private:
STDMETHOD_(ULONG, AddRef)()=0;
STDMETHOD_(ULONG, Release)()=0;
};
the errors:
(to the first line)
C2332: 'class' : missing tag name
C2011: '__unnamed' : 'enum' type redefinition
C2059: syntax error : 'constant'
C2143: syntax error : missing ')' before '>'
(to the second line)
C2059: syntax error : '('
I tried to solve all these errors, but with no luck. Can anyone help me?
Thank you!

Can't see anything wrong here. What I normally do in these cases is dump the pre-processor output and see if any macros are messing stuff up (see what the compiler sees). To do this you add the "/P" option to the compiler setting and rebuild. When you do this the build will appear to succeed with no errors - Don't get excited, it's just the preprocessing that has succeeded. For every .CPP file there will be a matching ".i" file with all macros fully expanded. Find a .CPP file that includes the problematic definitions and open the corresponding ".i" file. Look for your problem class - Perhaps by searching for "_NoAddRefReleaseOnCComPtr". Look for anything weird.

NOTE: Changed the "/P" above from "/O" (/O is wrong).

Thank you for your answer, Steve. I just need one more thing: where do I change the compiler settings?
Patrícia

I use MSVC6. This is how I setup the compiler to dump the preprocessor output:
1. Select "Project->Settings..." from file menu.
2. Select "C/C++" tab.
3. Click in the "Project Options" edit control and scroll to the end.
4. Add the "/P".
Remeber to remove the "/P" when you're done.

Any module to encode and decode from bufferarray with a short time?
Now, i want to encode buffer array of bmp type to another type with smaller size of buffer array, but take a little time.
With Jpeg type, it take 30 - 40 ms for encoding and decoding, i am finding another module to take about 10 ms
Thanks.

I'm making a data logger using a CListCtrl. my problem is when a new row of data is inserted at the bottom of the list, the scroll does not scroll-down and the list display remain at the top.
what I want to happen is to make the vertical scroll, to scroll-downwards automatically so that the latest data received can be easily seen during actual logging of data.
Hope you can help me with my problem!

When you add a new item to the CListCtrl, use the EnsureVisible() function to make sure that the new item is visible.

I think you could send it a scroll-down message like:
m_List.SendMessage(WM_VSCROLL,MAKEWPARAM(SB_BOTTOM,0),0);
this is this.

MSDN says when EnsureVisible is used, the item is shown at any cost, atleast partially. If needed, it is scrolled automatically too.

Yeah CDC objects.
Instead use HDC.

It depends on what you mean by "pass" MFC objects and what kind of MFC objects you are "passing".
For instance you should never access any GUI objects from a worker thread to prevent a deadlock situation. Read this[^] if you want to know more. This article is also great to know about thread handling.
In the article forum that belongs to the article there is also a discussion regarding your original question.
I know that CAsyncSocket has some issues when being accessed from different threads, but I can't remember them at the top of my head.
Creating MFC objects, such as CString objects, on the heap and "pass" them to another thread using ::PostMessage is always save provided that you forget about the object in the thread that created the object setting the pointer to NULL and you only have one receiving thread.
You could also use some container class, such as std::queue, to "pass" objects from one thread to another. But then you have to provide synchronization with mutual exclusions such as CRITICAL_SECTION to prevent two threads accessing the same object simultaniously. You simply "lock" the container when accessing objects in the container and "unlock" the container when you're done.
Hope this helps

It's supposed to be hard, otherwise anybody could do it!
