I found the answer in an article on Newcomer's site:

http://www.flounder.com/updatedata.htm

I went through my program and commented out all instances of UpdateData(). Voila – problem gone. I may need to clean up a few problems using the control variables, but the problem that’s been driving me insane is solved. The cursor is unstuck.

In the application wizard, next to the last screen there is an option to have a Properties window added to your MFC Doc/View app. It is static, what does it take to make it functional?

Ehum, some programming?

I recommend you implement some type of publish/subscribe pattern[^] where anyone who thinks he's got the focus, can publish a set of properties. The properties window will be a subscriber.

Hi!
I got the following linker error:

Error 1 error LNK2001: unresolved external symbol "public: void __thiscall player::writeNameOnTexture(void)" (?writeNameOnTexture@player@@QAEXXZ) battingTeam.obj

How do I resolve this error?

It means the linker didn't find a body for the function. Did you forget to write the function body ?

It means that the public method void writeNameOnTexture(void) of the class player could not been found. Probably you forgot to write down the body of it.

Implementing timeout in downloading a webpage

Hi all,

i have written a code to download a webpage using WinInet api's. My code is as follows

InternetCanonicalizeUrl(site,sCompareURL.GetBufferSetLength(MAX_BUFFER_SIZE),&dwLen,ICU_BROWSER_MODE);
HINTERNET Ihandle = InternetOpen("Internet Explorer6.0.2900.2180", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, NULL);
HINTERNET hFile = InternetOpenUrl(Ihandle,site,NULL,0,0,0);
BOOL bRet = InternetReadFile(hFile, szBuffer, MAX_BUFFER_SIZE, &nSize);
if(!bRet || nSize <= 0)
	break;
szBuffer[nSize] = '\0';
m_sHtml += szBuffer;

This code is working fine, but i want to implement time out in this, i.e i the specified page is not download in specified time then time out shold be displayed. How can i implement this?

Thanks in advance

You may try to set an option via InternetSetOption[^]
(the INTERNET_OPTION_RECEIVE_TIMEOUT flag looks promising, but I never made a test).

I know that if use the SMTP protocol, I should use the socket to create link with server.
And then
HELO SERVER
USER
PASS

but if I donot use the socket and I want to achieve the SMTP protocol , how should I do ?
Can someone give me suggestion?

Translate in to metaphor:
I know that to send a mail I have to plug to the network and then send it.
But if I don't use any network and I want to achieve the sending on the mail how should I do?

Frankly ... Or you use an SMTP service library (that use the socket internally, so it is not proper to say you're "not using socket") or ... try concentrate a lot, may be telepathy will work!

I'll try an answer: Write a socket client that implements at least RFC 5321 and RFC 4954, both protocols are typically needed to be able to send emails.

Alternatively use a networking library that offers an SMTP client/example (e.g. libcurl, PichatCore, QT), the code to send an email could look like this:

CClientSmtp client; 
client.SetRequestServer("mail.example.com", 25, "example.com"); 
client.SetRequestEnvelope("sender@example.com", "receipient@example.com"); 
client.SetRequestData("Subject:Test email\n\nHi! I am hungry, please send some pizza."); 
client.Request(); //send request to server after email was put together

You need to decide if you want to implement everything yourself or take an existing C++ library. First will teach you a lot about networking protocols, later gives you the result right away. Hope this helps! Smile | :)

what is the format of time you are having? If in MFC its easy to use CTime and CTimeSpan classes.

psuedo code:

CTime curTime(...);
CTimeSpan span(7/*Days*/, 0,...);

Ctime newTime = curTime - span;

Based on what? Is it a CTime object? Is it a time_t variable? If you have the number of seconds since some epoch, can't you just subtract 86400 * 7 seconds?

        Excel::_WorksheetPtr pSheet = XL->ActiveSheet;

        Excel::RangePtr pRange = pSheet->Cells;//on this line error is occur

        Excel::RangePtr pBeginRange = pRange->Item[1][1];

        bstr2 = SysAllocString(wsz2);

        // create safearray
        SAFEARRAYBOUND rgsabound[2] = { 0 };
        rgsabound[0].cElements = 1; // num rows
