i tried the the link that u had sent...
i.e. http://www.codeproject.com/dialog/statusbarmsgwnd.asp

well, i went through the code and tried to include it in my application. first i just included the stuff in the initdialog function to check whether it works.. well,to my pleasure, it worked. but then when i tried porting it to the actual location, it failed. i have created a thread in the application and want to call the code within the application. but when i do so, the application fails...it exits forcibly...

a portion of the code is shown below:

DWORD WINAPI CDlg::TestThread1(LPVOID lpParam)
{
CDlg* pThis = (CDlg*)lpParam;
while(1)
{
if(pThis->m_hCommEvent1)
{
WaitForSingleObject(pThis->m_hCommEvent1, INFINITE);
CStatusBarMsgWnd* t_MsgWnd =
StatusBarMsgWnd::CreateObject(
_T("Some idiot has signed in !!"),180, 150, 4000,10,CRect(30, 30, 130, 110),pThis);
t_MsgWnd->PopMsg();
}
}
}

Can u suggest wat modifications should i do...

Does it bring up a message about a MFC__.DLL file? If so, try copying them from your development computer to the destination computers (in the same location that you found them in the development computer). Use the Windows search feature to find the files on your development computer.

You're welcome.

You can use the same function ShowWindow() for all MFC controls derived from CWnd. That includes static text controls.

If you are using MAPI try this. You should have a profile name supplied.

The above code might have some variables not declared. Pls check it out before using.

If you're wanting to write your own SMTP server application I recommend reading RFC 2821. In regards to your question about how to obtain an MX record for a particular domain (example: yahoo.com, hotmail.com, etc...), you will need to need to query DNS. A good place to start to would be to use google.com, or better yet, if you're just looking for a quick solution, try this link.

Your best bet is to relay through an existing mail server, just like Outlook Express does.

But if you really need to do it directly, and expect to run on Windows 2000 onwards, then checkout the DNS API, DnsQuery specifically.

Otherwise you'll have to look up the DNS spec, find out how to locate your local DNS server and do the query manually.

problems with ShowWindow()

AmericanBacon22-Jun-04 12:26

AmericanBacon

22-Jun-04 12:26

Purpose: I am trying to have an app that will detect when a new app launches so I can open my app(password protection) instead before proceeding with the original application the user tried to open.

Current Solution: using a windows hook to look for new processes and hiding the app window(with ShowWindow()) unitl my password protection has been completed.

PROBLEM: ShowWindow() works great for hiding apps such as IE and Word, but it is not working for games like starcraft, warcraft. While in a game Alt-Tab will not even take you out of the game and quite often Ctrl-Alt-Del will NOT bring you to the desktop to see the taskmanager. Should I be using a different function call than ShowWindow()? Or is there a better way to accomplish this task?

Thanks,

Check my article about the little firewall I've designed.
http://www.codeproject.com/useritems/A_not_so_simple_firewall.asp
Here you can modify it the way you want to show a dialog box instead of a messagebox which asks you if you want to open the app or not.
Hope you find it helpful

   Remember that you may be dealing with a bad implemention of existing code, where a function might take a non-const pointer even though it does not modify it or its contents. Developers that get too comfortable with string objects can often find themselves in situations like that.

   The explicit cast to LPCTSTR is unnecessary; CString::operator LPCTSTR() takes care of that for you.

   Peace!

Use the resource editor in VC++.NET to create an icon, having it as a named resource in your project. Then in your dialog's OnInitDialog() function, type (replace IDI_DIALOG with the name of your icon's resource name.):

[...]

HICON hicon = AfxGetApp()->LoadIcon(IDI_DIALOG); 
ASSERT(hicon != NULL);

SetIcon(hicon, TRUE);

[...].

CPropertySheet::OnInitDialog() exception

Richard John22-Jun-04 10:57

Richard John

22-Jun-04 10:57

Using VS 2003, MFC 7.1, when creating a property sheet the internal CPropertySheet::OnInitDialog() will create an exception, an access violation writing a location. This is observed in the VS debug output window, and surrounding the OnInitDialog call with some TRACE statements will prove where it's coming from.

I have experimented by creating the simplest apps with CPropertySheets I can imagine, and the exception always occurs. True for both static and dynamic MFC linking, various runtimes, etc.

Any suggestions? Has anyone else seen this also?
