this one helps. You can use the MessageBox found int Extended WPF Toolkit™ Community Edition.
In its documentation there are two events called
code :
CloseButtonClicked 
Closed

MessageBox with timeout OR Closing a MessageBox from another thread

MessageBox with timeout OR Closing a MessageBox from another thread

wish of those help I noticed that if the main thread simply exits the application while the other thread still has the ::MessageBox open, that the MessageBox is being adopted by a process called CSRSS. This solves my problem, since this only requires a time-out on the Event in the main thread (WaitForSingleObject with timeout).
However, this raised another question: https://stackoverflow.com/questions/3091915/explanation-why-messagebox-of-exited-application-is-adopted-by-winsrv.

fixed the issue. Will look into that further Just before you begin the encryption process, install a WH_CBT hook, and in its callback watch for an nCode of HCBT_CREATEWND. If you get a matching class name ('#32770 (Dialog)' ?) and a matching title either return a nonzero value from the callback, or if that doesn't work post a WM_CLOSE (or a BM_CLICK to a relevant button if selecting an option is necessary). Uninstall the hook after the process for not messing with every possible dialog your application pops up.

Hope that helps It might look like a big overhead at first, but I would suggest using an IProgressMonitor which shows the progress of your task.
The user will know whats going on when he/she sees a progress bar, rather than a dialog that looks like the gui is frozen.
code :
public static void main(String[] args) {
    final Display display = new Display();
    final Shell shell = new Shell(display);
    shell.setLayout(new FillLayout());

    BazMessageDialog dialog = new BazMessageDialog(shell, "Information", null, "Getting List From Server", MessageDialog.INFORMATION, new String[]{"OK", "Cancel"}, 0);
    dialog.open();

    /* Do your stuff */

    dialog.reallyClose();

    shell.dispose();
    while (!shell.isDisposed()) {
        if (!display.readAndDispatch()) {
            display.sleep();
        }
    }
    display.dispose();
}

public static class BazMessageDialog extends MessageDialog
{

    public BazMessageDialog(Shell parentShell, String dialogTitle,
            Image dialogTitleImage, String dialogMessage,
            int dialogImageType, String[] dialogButtonLabels,
            int defaultIndex) {
        super(parentShell, dialogTitle, dialogTitleImage, dialogMessage,
                dialogImageType, dialogButtonLabels, defaultIndex);
        setBlockOnOpen(false);
    }

    public void reallyClose()
    {
        cancelPressed();
    }

}

it helps some times Well, guessing from your tags. I think you are talking about Window Forms in C#. Yes, there is a way to do that. But not as simple as a message box. All you have to do is:
Create a Form and Design it like a MessageBox Override the PreviewKeydown event handler ( or overriding KeyPress event handler will also work) And then match the case when Space key is pressed.
code :
switch (e.KeyCode)
{
    case Keys.Space:
       //Call The Event handler for Ok Button
        e.Handled = true;
        e.Suppressed = true;
        break;
}

I hope this helps . QMessageBox::question() is a static method so m_warningMsg is not the QMessageBox that is displayed, as you have passed as a parameter to this as a parent then we can find that QMessageBox (note that it is not necessary to use m_warningMsg) using findchild():
code :
QMessageBox::StandardButton reply = QMessageBox::question(this,"Warning","Do you really want to close the connection",QMessageBox::Yes | QMessageBox::No);
if(reply == QMessageBox::No)
{
    return;
}
void Window::closeConnection()
{
    QMessageBox *mbox = findChild<QMessageBox*>();
    if(mbox)
        mbox->close();
    close();
}
