Well, I think you may test in both cases.

The C++ Standard guarrantees that new(nothrow) returns NULL if fails.

What if new fails?

Really?
But if there is no exception thrown and there is no pointer set to 0. What else should be testet?

I have a program, written in MFC C++... what change (or add) in this program that work as service.

IMO, you should create a new windows service project and then add your MFC project files to this new one.
Don't know if there would be a direct way of achieving this.
Somethings seem HARD to do, until we know how to do them.

Actually wizard will create service for you.
I guess you need to choose ATL COM project and then it gives option to create service. Nor sure about the project type but you can find it easily.

I want to create About dialog after created main dialog. All I did as follows:
- create about dialog
- in Resource.rc, I add this:
STRINGTABLE
BEGIN
IDS_ABOUTBOX "&About ..."
END
- in CMyDlg.h, declare
afx_msg void OnSysCommand(UINT nID, LPARAM lParam);
- in CMyDlg.cpp, implement this method:
void CMyDlg::OnSysCommand(UINT nID, LPARAM lParam)
{
if ((nID & 0xFFF0) == IDM_ABOUTBOX)
{
CAboutDlg dlgAbout;
dlgAbout.DoModal();
}
else
{
CDialog::OnSysCommand(nID, lParam);
}
}
- in CMyDlg.cpp, register notify
BEGIN_MESSAGE_MAP(CAboutDlg, CMyDlg)
ON_WM_SYSCOMMAND()
END_MESSAGE_MAP()
that's all, but it doesn't work. I try to debug and found that it doesn't come into OnSysComand() method. What do I miss here?
Thank you very much,

I guess you need to add the handler in the WinApp class.
and by default MFC will add about dialog unless you explicitly removed the about dialog check box.
|
|
|
|
|
Thank you for reply me, SandipG.
I don't have WinApp class, it's MFC project with Dialog based.
|
|
|
|
|
haha  without application class you cant have MFC application.
I am talking about the class which has Initinstance function.

This is the wrong message map. It should be:
BEGIN_MESSAGE_MAP(CMyDlg, CDialog)
ON_WM_SYSCOMMAND()
END_MESSAGE_MAP()

Thank you DavidCrow
It works, but with a little strange. Whenever I right click application in taskbar and select "About ...", nothing happens. Then, I press Alt, the About dialog shows up.
I don't know why????

Does void CMyDlg::OnSysCommand() get called?

yes, it does. Here is the source code of OnSysCommand:
void CMyDlg::OnSysCommand(UINT nID, LPARAM lParam)
{
if ((nID & 0xFFF0) == IDM_ABOUTBOX)
{
CAboutDlg dlgAbout;
dlgAbout.DoModal();
}
else
{
CDialog::OnSysCommand(nID, lParam);
}
}
When I try to debug, it stops at (1) until I press Alt. After that, the About dialog shows.
