It is better to send a user defined message to your dialog class. And in the event handler of this message, update the data.

If I do it in that way
m_pTargetDlg->SetWindowText(str);

it works.

But this is only for testing.

I am trying now to call a member function, which tries a cyclic reconnect to a telnet server after the connection has been closed by the server side.
The connect method works, but if I start it in the timer callback it crashes.
The timer only runs ones. After the first callback I stop the timer and call the connect method, but it crashes.
Hard work, I don't know why...

That would depend on whatever application that is the receipient of the mouse clicks, and I would imagine that a programmer won't think of a situation in which the mouse button can go up without going down first. Just because it "works" in certain cases doesn't mean it's correct. If you had tried simulating keyboard input with keys going up without coming down first you get fantastic results.

Have your taskbar be on the bottom of your primary monitor and visible and run this snippet. Does the start menu pop up? Works for me...

mouse_event(MOUSEEVENTF_MOVE | MOUSEEVENTF_ABSOLUTE, 0, 65535, 0, GetMessageExtraInfo());
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0 ,0,GetMessageExtraInfo());
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0 ,0,GetMessageExtraInfo());

tool tip like dialog

Hi,

I am coding an application in vc++6, mfc. I have some sort of bar graph in which when I click on one of the bars a small dialog pops up giving information about that bar. I want the dialog to close automatically when I click anywhere outside it and not when an OK button is pressed. I tried with OnKillFocus and EndDialog but it is not working.

void CChartInfoDisplay::OnKillFocus(CWnd* pNewWnd) 
{
	
	EndDialog(0);
	CDialog::OnKillFocus(pNewWnd);

	// TODO: Add your message handler code here
	
}

Please can you tell me how to make a dialog box close when the user click anywhere outside it?

Thanks,
Tara

If you have a modeless dialog (activated with Create), I think you should try WM_ACTIVATE notification, sent to your dialog when another window is activated.

Make a handler for this message and watch for WA_INACTIVE value of WPARAM.

Otherwise, if your dialog is modal (activated with DoModal), then I think you should process WM_NCACTIVATE notification with FALSE value of WPARAM.

I hope it helps.

It worked! This is what I did.

BOOL CChartInfoDisplay::OnNcActivate(BOOL bActive )
{
	if (bActive == FALSE)
	CDialog::OnOK();

	return TRUE;
}

I tried with

afx_msg void OnActivate( UINT nState, CWnd* pWndOther, BOOL bMinimized ); but I got some errors I could not understand.

Thank a lot.

Try with

afx_msg void OnActivate( UINT nState, CWnd* pWndOther, BOOL bMinimized );

nState must be WM_INACTIVE, then call OnOK();

Is there any registry path where all the installed components in the system are listed?
I found that components to be uninstalled are listed in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall. Just like that i want to know whether any place is there where all the installed components are listed.

If they did not use MSI, then there is almost no chance of locating everything.
If they were installed using MSI, then you can use the MSI API to get lists of installed 'packages'. A product does not necessarily have to be installed using MSI to end up in the 'add/remove programs' list.

I think you can use the WebBrowser ActiveX control. Go to dialog editor, right-click on dialog, select Insert ActiveX Control, and then select Microsoft Web Browser.

Then create a control variable for this new control.

Next call Navigate2 member function in this manner:

_bstr_t urll1(_T("file://path-to-your-html-file"));
_variant_t url2 = url1;
m_cMyControl.Navigate2(&url2, NULL, NULL, NULL, NULL);

Alternatively, you can format a nice message using some editor (like Write) and save as RTF file or resource. Then load this content to a rich-edit control (CRichEditCtrl).

I hope this helps.
