Can you not simply query the MX record (using DnsQuery())?

Thanks for the kind reply...

i am not familiar with MX record nor DnsQuery, maybe you can refer me to a code snippet or documentation?

thanks again

See DnsQuery(..., DNS_TYPE_MX, DNS_QUERY_STANDARD, ...).

the MSDN reference doesn't help me since i am not familiar with the subject....

can you refer me to a code snippet that uses DnsQuery to get the mail server ?

also, i need to know the current user email address...can u help there as well?

thanks again for all the kind help

Can't you just Google for an example?

in a Small research i did, i found out that in order to use DnsQuery you need to specify the name of the owner of the record set queried (first parameter). this isn't good for me.

i need to explain exactly what i am planning to do:

i need to retreive a SMTP server i.e Mail.yaron.net then i need to retrieve the current user email
i.e yaron@yaron.net......

problem is i can't do either with what you have suggested.....

i was trying to use Outlook automation, but couldn't find how to retrieve the SMTP server using that....

any suggestions? references?

thanks

What are you talking about? This should work fine:

DNS_RECORD *ppQueryResultsSet = NULL;
DNS_STATUS statusDNS = DnsQuery("yaron.net", DNS_TYPE_MX, DNS_QUERY_STANDARD, NULL, &ppQueryResultsSet, NULL);
if (statusDNS == ERROR_SUCCESS)
    cout << ppQueryResultsSet->Data.MX.pNameExchange << endl;

Hi,

I used richeditcontrol2 to use as it to display readonly text (as static edit box). i want to display the text in some color other than black,
i created richedit control as follows and tried to display the text ,but its displaying some junk text ..please do inform me regarding this ....

LPTSTR temp = (LPTSTR) "test";
CHARFORMAT ch;
m_Richer.GetSelectionCharFormat(ch);
ch.cbSize = sizeof(CHARFORMAT);
ch.dwMask =CFM_COLOR;
ch.crTextColor =RGB(120,250,123);
GetDlgItem(IDC_RICHEDIT24)->SetWindowText((LPTSTR)"HELLO");

I think you should use _T macro:

LPTSTR temp = _T("test");

and

GetDlgItem(IDC_RICHEDIT24)->SetWindowText(_T("HELLO"));

I hope it helps.

In addition, "ch.cbSize = sizeof(CHARFORMAT)" must be done before "m_Richer.GetSelectionCharFormat(ch)", but actually this is not even needed in case of MFC.

You should use SetSelectionCharFormat as was suggested by DavidCrow. Note that before this you have to specify the range where the colour must be applied. For instance, if you want to change the entire text, try this:

CHARFORMAT cf;
cf.dwMask = CFM_COLOR;
cf.crTextColor = RGB(120, 250, 123);
m_Richer.SetSel(0, -1);
m_Richer.SetSelectionCharFormat(&cf);

So shouldn't you be calling SetSelectionCharFormat() then?

Why aren't you using:

m_Richer.SetWindowText("HELLO");

rtf sucks. The thing to do is open MS word, create a document formatted as you wish, save it to rtf, then read the rtf text file to find out the formatting.

Pre and post fix this formatting to your desired text, then add it to your rich edit control.

Control Event Handler

I create a control this way:

hDrawingControl = CreateWindowEx(WS_EX_LEFT,
"Static",
NULL,
WS_CHILD|WS_VISIBLE|WS_BORDER|WS_TABSTOP,
aLeftTop,
aBottomRight,
aWidth,
aHeight,
parentHandle,
NULL,
hInstance,
NULL);

How can I register an event handler to this control?

In what? raw win32 / MFC / ATL / other?

Daniel Kanev5-Jul-06 5:12

Raw WIN32. MFC is also interesting for me. So if you know both methods, please tell me!

Thank you!

Sorry, I spaced -- static controls don't support events.

In general:
MFC supports message cracking; there is a tool built in to visual studio to help with this or you can manually modify the message map macros.

win32 makes you do some more work on your own. In general, most controls (and certainly the system controls -- static, edit, button, etc) will notify you via a WM_COMMAND message sent to your WndProc. See the WM_COMMAND docs in the msdn, but basically you check WPARAM for the window identifier, LOWORD(LPARAM) for your child window handle, and HIWORD(LPARAM) for your notification code. See the docs for the various controls to see lists of the notification codes. Or just grab them from the headers -- seach for, eg, EN_CHANGE (code for an edit control changing).
