There are several solution. One solution for a popup menu is a context menu. Search context menu in help or MSDN.
I do not have access to my source code right now. I can give you an example of a context menu tonight when I have access to my workstation.

Try this:
CPoint p;
GetCursorPos(&p);
CMenu menu;
menu.LoadMenu(IDR_MY_MENU)
CMenu* pPopup = menu.GetSubMenu(0);
ASSERT(pPopup != NULL);
pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, p.x, p.y, AfxGetMainWnd());
note: the commands will be routed to the main window. To rout the commands to another place, replace AfxGetMainWnd() with a CWnd* of the window you want to get the messages.

With Visual C++ Version 6.0 I face a problem that the next property page is not completely drawn after the message box has been closed. In the OnWizardNext() function I check the input fields and if an input is not acceptable I invoke an AfxMessageBox() function with Yes No button to continue or not. If the return value is IDNO I set the return value of the OnWizardNext() funtion to -1, so there is no jump to the next page. If the return from the message box is IDYES I set the return value to the default OnWizardNext() reurn wich is 0. Then a jump to the next page is performed but the next page is only partly drawn. The drawn area corresponds a pproximately with the rectangle including the controls in previous page.
Can some body give me indications how I can solve this problem ?

I have a CListCtrl embedded in a CFormView. Basically all I'm trying to do is make it so that long strings to not get cut off with a "..." at the end. In other words "The quick brown fox jumped over the lazy dog" will appear as "The quick brown fox jumped over ..." Pain in the butt it seems. Anyway if anyone has a solution to this problem, please respond. Thanks.

seems you are not familiar with the member functions.

If two applications running on one PC use the following bind call, what will happen?
sock.sin_family = PF_INET;<br />
sock.sin_addr.s_addr = htonl(INADDR_ANY);<br />
sock.sin_port = htons((u_short)0);<br />
<br />
if (bind(*lpSock,(LPSOCKADDR)&sock,sizeof(sock)) != SOCKET_ERROR)<br />
nRet = ENOERROR;
When a UDP message comes in with the dest. port of 2000 (for example), which application will get it (or will both)? I'm guessing that it cannot be determined/random? I really don't have any idea.
I realize this is a fairly basic sockets question but I have not been able to find any information on how this situation would behave.
Thanks for any info. you may have.

I think that no more than one application can bind to a given port at the same time.

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

Thanks,
since the port number is 0 here, doesn't that mean that it will attempt recv. from all port numbers?

Hm... have you tried using port 0?
You can't bind to port 0!

Yes, I have tried - we have software that has been running for years this way. The problem came up when another application sent/rcvd UDP messages at the same time. I'm guessing that they are using the bind with port 0 also (for the rcv socket), and they are getting some of the UDP messages that were meant for us.

Aah.. but then it must be specific for the UDP protocol to bind on port 0!
I don't know UDP that much.

Thanks anyway. Maybe I will post another message with UDP and port 0 in the heading. This is very difficult to find any information on since 90% of programmers are using TCP instead.

Don't do that!
It's a bad thing to re-post a message, if you have bad luck someone will give you a lesson...
But click the "Modify" link in your message and change the subject!

as far as I know, trying to bind to port 0 using UDP will just make it pick its own port that isn't already allocated. You can't have 2 programs running using the same port.
http://www.ecst.csuchico.edu/~beej/guide/net/html/syscalls.html
Its for linux but its the same case as far as I've tested (lots in the last month) as winsock. I've just finished a biggie UDP based program and wouldn't let it try to bind to port 0 if my life depended on it, I'd rather know where it was going thanks

I need some help. I need source code that will recursively search the registry and delete text found. It would need to work on 95/98/NT/XP/2000. I'm looking to return a list (perhaps in a list box) of all keys (ALL TEXT) that were found. If that Text appears anywhere in registry I want it added to my list. Then I can select/deselect what I wish and then delete the selected items. Allow someone to highlight and delete specific ones.
Any ideas?
Any help is appreciated.
Cheers,
Derek

try this:
HKEY hKey = NULL;
CString csCadenaA[10];
CString csCadenaB[10];
csCadenaA[0] = "Software\\akuna\\matata\\";
csCadenaB[0] = "LionKing";
csCadenaA[1] = "Software\\lilo\\stitch\\";
csCadenaB[1] = "ls";
for (int i=0;i<10;i++)
{
RegOpenKeyEx(HKEY_LOCAL_MACHINE,csCadenaA[i],0,KEY_ALL_ACCESS,&hKey);
if (hKey != NULL)
{
RegDeleteKey(hKey, csCadenaB[i]);
}
}
OK, the strings used in this sample are stupid, but it works...
Hope this helps...

How do I specify an Icon and a default File Extension to my MDI document ?
Please help
|
|
|
|

You can specify an extension in the wizard when you create your MDI project.
The Icon can you just replace, that one you have as standard can you find in the res directory I think. Just replace the icon and TADA!

Once I have created a project how do I specify the extension ?

I haven't used SDI/MDI or neither MFC for long so I don't know! 
Someone else have to take over now!

In your string table, you will find an entry for IDR_xxxxxxTYPE, where xxxxxx is your original file type. Replace the text in the string to:
\nJunk\nJunk\nJunk Files (*.junk)\n.junk\nJunk.Document\nJunk Document
Where Junk is your document type.
Hope that helps.

Am I missing something? If I want to hook the minimize button, I add an OnSysCommand() method and look for SC_MINIMIZE, right?
What would make my CPropertySheet-derived dialog behave differently? I get the SC_CLOSE, but no SC_MINIMIZE.

No no, don't everybody rush to help out.
It turns out that you need to specify the WS_MINIMIZEBOX when you actually create the CPropertySheet-derived window (ie, pDlg->Create(whatever, WS_OVERLAPPEDWINDOW); // <- included in there). Specifying it later did not seem to work.
And using ModifyStyle() in the InitDialog() showed the minimize box, but wouldn't actually allow the dialog to send the associated WM_SYSCOMMAND. Weird.
I lurve MFC.

That kind of jogs my memory. I am not sure if this is what you were experiencing, but you need to make a call like this:
::SetWindowPos(hWnd, NULL, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER | SWP_NOACTIVATE | nFlags);
after certain style changes with SetWindowLong in order for the style to be completely set into the window. Maybe the WS_MINIMIZEBOX is one of those styles.
