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.

     // Get a Profile admin object<br />
     if ( FAILED ( hRes = MAPIAdminProfiles ( 0L, &pAdminProfiles ) ) )<br />

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?

Bringing desktop window to the top without taking focus

casid22-Jun-04 9:47

22-Jun-04 9:47

Off and on for some time I've tried to find the best way to bring a window (whose parent is the desktop) to the top of all the other application windows on some particular event. They could very well be using another application window at the time so I can't allow it to take the focus away as this could result in lost keystrokes. My current implementation of this is basically the following:

HWND hwnd = ::GetForegroundWindow();
::SetWindowPos(myhwnd, hwnd, 0, 0, 0, 0, SWP_NOSIZE|SWP_NOMOVE|SWP_NOACTIVATE);
::SetWindowPos(myhwnd, hwnd, 0, 0, 0, 0, SWP_NOSIZE|SWP_NOMOVE|SWP_NOACTIVATE);

I've investigated numerous other ways over time. This works well but doesn't always work perfectly. Some times focus is stolen and sometimes the z-order isn't correct. These are rare cases and usually involve some specific other application that was in use at the time.

I'm wondering if anyone could offer solutions they've tested and used in the past for performing something similar?

Craig

Sorry, I meant to code it:

::SetWindowPos(myhwnd, hwnd, 0, 0, 0, 0, SWP_NOSIZE|SWP_NOMOVE|SWP_NOACTIVATE);
::SetWindowPos(hwnd, myhwnd, 0, 0, 0, 0, SWP_NOSIZE|SWP_NOMOVE|SWP_NOACTIVATE);

How to concatenate a string and an int

Re: concatenation

ov22-Jun-04 9:30

22-Jun-04 9:30

There are many ways. It depends of type of your string. For null-terminated const char * you can use this one:

char res[128];
const char *str = "Result is: ";
int num = 10;
sprintf(res, "%s%d", str, num);

well a solution would be this one:

int x=466;
char conc[1024];
_itoa(x,conc,10); //converts the int to string now conc="466"
strcat(conc," is a converted number");
//now conc is "466 is a converted number"

Hope this is what you want
