Dialog BOx Question

CSharpDavid

I have a dialog with a timer that check to see if it can close itself when it can I kill the timer and send a PostMessage(WM_CLOSE); The dialog is very slow to close , If I click the system close button, it is immediate Also Tried SendMessage. Whats the best way to close the dialog ? NB: THe main dialog has a timer doing serial comms. Win CE 3.0 Thanks .Confused

David, what's your platform ? Is it a HPC2K Industrial device ? In this case try to move the EXE to the RAM instead of running directly from the FLASH Memory : I've found that many times this solved my problems....

I do it the following way:

...

class CConnMsgDlg : public CDialog
{
...

// Implementation
protected:
// Generated message map functions
//{{AFX_MSG(CConnMsgDlg)
virtual BOOL OnInitDialog();
...
//}}AFX_MSG
afx_msg LRESULT OnEnd(WPARAM wParam, LPARAM lParam);
DECLARE_MESSAGE_MAP()

...

private:
static const UINT MY_WM_END;
};

...

/////////////////////////////////////////////////////////////////////////////
// Message table

const UINT CConnMsgDlg::MY_WM_END =
RegisterWindowMessage(_T("MY_WM_END-{29813B84-DD1E-11d7-9B13-0002B32C4875}"));

BEGIN_MESSAGE_MAP(CConnMsgDlg, CDialog)
//{{AFX_MSG_MAP(CConnMsgDlg)
...
//}}AFX_MSG_MAP
ON_REGISTERED_MESSAGE(MY_WM_END, OnEnd)
END_MESSAGE_MAP()

BOOL CConnMsgDlg::OnInitDialog()
{
CDialog::OnInitDialog();

// TODO: Add extra initialization here

    // Create the thread and start it

return TRUE;  // return TRUE unless you set the focus to a control
              // EXCEPTION: OCX Property Pages should return FALSE

}

LRESULT CConnMsgDlg::OnEnd(WPARAM wParam, LPARAM lParam)
{
EndDialog(wParam);

return 0L;

}

void CConnMsgDlg::ThreadFnc()
{
...

PostMessage(MY\_WM\_END, IDOK); // destroy the dialog

}

I have a dialog that starts a thread in the 'OnInitDialog' function. The thread reads some data from the serial port. This can take a long time, so I do it in a own thread. When the thread is ready it post the message 'MY_WM_END', that I have registered in the message map. The 'OnEnd' function closes the dialog with 'EndDialog'.
