I know that, Mike. I was looking at my Oct '01 copy of MSDN. It's a bit aged.

When are you running the code you posted?
m_tnd.hWnd = pParent->GetSafeHwnd()? pParent->GetSafeHwnd() : m_hWnd;
I assume a valid HWND is required, have you checked that you have one?

Yes, the dialog's hwnd is valid. I have called the icon create method from OnInitDialog() after the CDialog::OnInitDialog() call. I have also called it from OnShowWindow(), but both fail.

PostMessage puts a message in windows queue and does not wait for it to be processed.
I know that windoze will not keep same message in the queue; however, I cannot make the following work:
PostMessage(NULL,WM_STATUS, 1, 1);
... process something
PostMessage(NULL,WM_UPDATE, 1, 1);
Only the first message gets processed - in my case by
CMainFrame::PreTranslateMessage(MSG* pMsg)
I just want to change status bar text “before and after” lengthy process.
Could anybody explain to me why the second message gets ignored please?
Do I have to use different method to accomplish this?
Thanks for your time
Cheers
Vaclav

Stop blaming Microsoft for your incompetency and read the documentation where you will find the SendMessage() API that blocks.
Hint: The next time you post your garbage "windoze" anti microsoft nonsense and I see it, I will surely flame you into a crispy critter.

Or the whole "you can't expect any messages to be processed on a thread when there's no code processing messages

Why are you passing NULL for the window handle? Why not post to the actual window
you want to receive the message?
If you want to handle the message like a thread message then you should do that
appropriately - in your thread class.

Thanks Mike,
the NULL is there because I was frustrated with he whole process and it works if I use only one PostMessage in a function.
I just tryed this code and it also does not process the WM_TEST message - which is still simple AfxMessageBox.
if(PostMessage(NULL,WM_TEST, 1, 1))
{
AfxMessageBox("PostMessage(NULL,WM_TEST, 1, 1) OK");
}
else
{
AfxMessageBox("PostMessage(NULL,WM_TEST, 1, 1) No good Not OK");
}

The message queue processing can't execute if your code after PostMessage is doing a long running routine because it's all in one thread. You really need to stop typing code and forum messages and spend more time reading until you understand how things work.

Thanks for reply.
...long running routine because it's all in one thread....
....
AfxGetMainWnd()->PostMessage(WM_TEST, 1, 1);
AfxGetMainWnd()->PostMessage(WM_TEST_1, 1, 1);
return strText;
This short code does not work either.
Only the first message is actually processed.
So what is MS definition of "message queue"?
It looks like there is no queue at all.
I'll check GetQueueStatus to see if it gets me some more info.

It appears you are not properly posting '<' and '>' characters

They hide that information in the documentation[^]

AfxGetMainWnd()->PostMessage(WM_TEST_1, 1, 1);
What is the values of WM_TEST and WM_TEST_1 and how are you trying to receive them?

Both WM_TEST and WM_TEST_1 are WM_USER defined messages.
For now CMainFrame::PreTranslateMessage(MSG* pMsg)
receives the messages and just does status bar text update plus AfxMessageBox for simple trace debugging.
Snippet here:
....
case WM_TEST: // WM_USER+7
{
m_wndStatusBar.SetPaneText (1, "Status : TEST TEST TEST TEST ", TRUE);
AfxMessageBox("TEST Update status ");
break;
}
case WM_TEST_1: // WM_USER+7
{
m_wndStatusBar.SetPaneText (1, "Status : WM_TEST_1 WM_TEST_1 WM_TEST_1 ", TRUE);
AfxMessageBox("WM_TEST_1 Update status ");
break;
}
...
I do not fully understand how to implement the retrun value of PreTranslateMessage.Either way - replacing the case break with return true or false did not make any difference.
I am still looking into GetQueueStatus and see if I can use it in
PreTranslateMessage.

Well assuming you actually have WM_TEST AND WM_TEST_1 defined with different values rather than the same WM_USER + 7 as commented in your code, if you change AfxMessageBox to TRACE statements you will see you receive both messages. If you give control of the message queue to the message box by popping it up the second one gets eaten before your code starts executing again.
