Derive your own class from CDialog and override the OnClose() function which is called by the system when the [X] button is pressed.
|
|
|
|
|
Just handle the cancel button click event.
void CYourDlg::OnBnClickedCancel()
{
AfxMessageBox("Don't close!");
}

He wants to catch the [X] in the system-menu, not the Cancel button ... 
Here's the code:
void CYourDlg::OnClose()
{
AfxMessageBox("Don't close!");
}
... and don't forget to add the ON_WM_CLOSE() macro in the dialog's message-map.

Hey that still works with System menu's [x]. Did you check that? but yes mentioning "WM_CLOSE" is required!

What do you mean by "mentioning WM_CLOSE is required"?

Assuming he's operating on a default dialog with OnCancel implemented, he can simply override it and handle it by the way he wanted. It works without him needing to make any extra effor. But ofcourse handling WM_CLOSE is the proper way. That apparently relates to [X] close!.

Actually I was searching for OnCancel but it's not there with 7.1 compiler. VS6.0 displays the cancel event handler as "::OnCancel". but in 7.1 it's generating OnBnClickedCancel.

Why would you suggest that? If you write your code in OnCancel(), then it would be obviously executed when the Esc key is pressed and also when the cancel button is pressed. Handling WM_CLOSE is the right way.

Yeah, nobody would want their application to get closed with an Esc. I really wonder why MFC has it that way :unsure:. So handling WM_CLOSE is the best way. Thanks for stressing that one out.  ![Beer | [beer]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/beer.gif)

You assume things.

That is by design. Pressing the Esc key in a dialog based app will execute some extremely old windows code. As a developer, you are not supposed to develop complex applications which is dialog based. As a user, he would always expect a dialog to get dismissed when the Esc key is pressed. For instance, if you right click on the desktop and choose properties, you will expect the properties window to get dismissed on pressing Esc. I am working on my first article, and I have elaborated on this dialog box closing glitch issue more clearly.

I stopped working with MFC quite a long time ago. Currently I am working on Windows Mobile and embedded C (Dynamic C). I have worked with MDI applications too, but for some reason I love dialog based applications and hooking and spying out stuff from within a DLL.

Yeah me too, in general I hate UIs to a good extent.

Hi.
First, I don't know if this is the right forum to post this question, if not, sorry and someone move this post to the right forum.
In the Web we can find some programs that telling you the microprocessor temperature, the fact is I don't trust in those programs, you know, spyware, risks performing low level routines, etc.
So I want to write my own program to "read" the micro temperature, the question is, where should I start?. I have good skills in MFC and also I know assembly, but I can't figure where should I start?.
My micro is a Peuntium 4, I think every micro is different so I'm looking for technical docs about my micro and motherboad, but all the documentation I found nothing says about routines to perform.
Any comment will be appreciated.
Thank you and regards.
Demian.

If your motherboard has a temperature sensor, use the Win32_TemperatureProbe WMI class.

Thank you very much for your time.

Hello everyone,
I am learning how to use Excel to connect to other external data source (like database). What I want to do is to develop a plug-in for Excel and automatically access external data source, then display it in Excel tables.
Are there learning resource? I have tried to search in MSDN, but can not find any learning resources.
thanks in advance,
George

It sounds like you need to use the Workbook_Open event.
