You can't using MessageBoxEx(). You'd have to write your own dialog class, and send it some sort of message from another thread.

Actually, you could simulate a mouse click on the message box to click one of the buttons...

I want to do like this
But I don't know how to simulate a click on the button.
Can you tell me how to finish this function?
|
|

There are two ways:
1. Get the location of one of the buttons (use GetWindowRect()) and send a WM_LBUTTONDOWN message.
2. Send a WM_COMMAND/BN_CLICKED message to the dialog, with the IDOK identifier.
I would probably do the second one. Hope this helps,

I do like below:
PostMessage(WM_COMMAND,IDYES);
SendMessage(WM_COMMAND,IDYES);
But neither of them can shut up the dialog.
what's wrong with me?

Are you sending it to the correct window?
You have to do:
PostMessage(WM_COMMAND, MAKEWPARAM(BN_CLICKED, IDYES), (LPARAM)hwndYesButton); after getting the window handle to the yes button.

Oh
I call the function after I click a button on my main dialog.
Can that work?
In addition
"hwndYesButton" is an undeclared identifier in my project.

Of course that would not exist in your project.
That's the handle of the "Yes" button in your dialog, or maybe the "OK" button. You have to define in and then the value can be obtained by calling GetDlgItem( HWND hDlg, int nIDDlgItem ) or the CWnd::GetDlgItem( UINT nID ). Then you should call the function that Ryan told you earlier:
PostMessage(WM_COMMAND, MAKEWPARAM(BN_CLICKED, IDYES), (LPARAM)hwndYesButton);

You will have to call the function from a different thread, but it should work. You won't be able to use the MFC window pointer. You'll need to use the m_hWnd member of the CWnd pointer. But yes, it should work after clicking on a button from your dialog.
You will need to declare hwndYesButton as an HWND and get the window handle of the yes button (not an easy task. I'm not sure exactly how to do it).

Do you think that sending a WM_CLOSE message to the dialog would take of everything? I have done it with a Splash window that I designed once and yes I used a thread for it.

Hmmm, maybe. Remember that the MessageBox() function returns a value depending on which button was pressed. What does it return in it gets a WM_CLOSE. His code will have to make sure that it does the right thing...

It always returns zero (if the window processes the message). I think Aleon just wants to close the dialog. But if it is a modal dialog box then EndDialog can be used and the result can be passed as a parameter. If not then your answer still remains the best solution (in my opinion).

Simply tell the dialog to shut up and I don't know what could be wrong with you. What kind of symptoms are you experiencing?  Just joking.
Seriously, Ryan's last post gives you the correct answer. Where exactly are you calling PostMessage and SendMessage?

Actually, I am an "engineer" but since I cannot find a job I think I should consider your suggestion. It would be so much fun to play with peoples' minds and tell them that they are crazy when they're just fine.

Hello,
I have a already built application using MFC. This application uses Context-Sensitive help ( While building they choosen a Context-Sensitive help option for Dialogbased application). The hlp folder of this application contains "afxdlg" rich text document ( this comes by default ).
I want to modify this file to add my own document. But when i modified and recompiled using Help Work Shop the following
error is coming :
C5011: Error: D:\MFC_help\HelpTest\hlp\afxdlg.rtf :
Cannot open the file "{\rtf1\ansi\ansicpg1252\uc1 \deff0\deflang1033\deflangfe1033{\fonttbl{\f0\froman\fcharset0\fprq2{\*\panose 02020603050405020304}Times New Roman."
How can i avoid this and compile with out any error ?
Thank you.

I have an array in a struct and I am trying to allocate the correct memory size for the data that I need to put in it.
My data is words read from a file.
exp:
deg
active,frozen,stopped
ft/sec
meters
gallon
etc......
If I create a char array can I make each one of those an element of the array?
sj

127 for char
255 for unsigned char
[EDIT]
You can find this info in limits.h in the include dir of VC++.
