This is what I did to download a gif image from codeproject but ::recv will return after about a minute and return 0, can you help me out? I have not posted the whole code but everything goes fine except when it reaches ::recv
sockaddr_in server = {0};
pHostent = ::gethostbyname(_T("www.codeproject.com"));
server.sin_family = AF_INET;
server.sin_port = ::htons(80);
server.sin_addr = *(in_addr *) pHostent->h_addr;
nErrorTest = ::connect(socket, (SOCKADDR *) &server, sizeof(server));
::_stprintf(szSendData, _T("GET /info/stuff/codeproject_w2k_bg.gif\r\n"));
nErrorTest = ::send(socket, szSendData, ::lstrlen(szSendData), 0);
nErrorTest = ::recv(socket, szRecvData, sizeof(szRecvData), 0);

That is not a valid HTTP request. Try using the WinInet API or the MFC wrappers for it. They will keep you from having to deal with much of the protocol level coding.

My application needs to store a float number into to a byte array at the specific location. i.e. at byteArray[0] to byteArray[3] will store that float number. wrote :
byteArray[0] = ((byte*)&floatNumber)[0];
byteArray[1] = ((byte*)&floatNumber)[1];
byteArray[2] = ((byte*)&floatNumber)[2];
byteArray[3] = ((byte*)&floatNumber)[3];
but after write into a file and read back then
cout << (float) byteArray[0] << endl;
doesn't get the correct answer.
How to modify above code???

union FloatToCharArray {
float f;
char c[4];
};
then, you use it like this :
FloatToCharArray ftc.f = 4.12;
cout << "chars are : " << ftc.c[0] << " " << ftc.c[1] << " " << ftc.c[2] << " " << ftc.c[3];

I stored ftc.c[0] to byteArray[0];
ftc.c[1] to byteArray[1];
ftc.c[2] to byteArray[2];
ftc.c[3] to byteArray[3];
then output:
cout << (float)byteArray[0] << endl;
doesn't give the correct number.
|
|
|
|
|
of course, it can't work, you are converting only the first char into float, not the 4 chars...
use ftc.f (in my union) to retrieve the float...

This will work a bit better:
cout << *((float*)*byteArray[0]) << endl;
However, using the union described above, you could write much more clear code:
union FloatWrapper
{
float myFloat;
unsigned char myBytes[4];
};
FloatWrapper someValue;
someValue.myFloat = 1.23;
cout << someValue.myFloat << endl;

I worked on it for 3 months.But i can't write a SMTP server.Any help? Thanks a lot.
Things like that don't last long.

Well, one could question why you would want to do that. I think you can get tons of SMTP servers (with code), can't you?
Anyway, even so, I think you could start off by telling us what knowledge you already have to contribute to this project. You would need skills on these areas:
1) TCP/IP, as a server, to receive SMTP connections. Possibly, also multithreading, if you want your server to be able to handle several requests simultaneously.
2) Command parsing. For this you would need to investigate the SMTP protocol details. Checkout http://www.ietf.org/rfc/rfc0821.txt[^]. I bet you will find it to be a gigantic task to implement a fully compatible SMTP server. But you could settle for starting small, maybe allowing for plain text (no attach) SMTP, and progress from then on. A good design would be the key for your project to be able to evolve in small steps.
3) Relay protocol (I think it is diferent) to be able to deliver e-mails to the destination.
4) Some form of UI, to configure accounts and things like that.
5) Some form of testing. This could be the simpler task, because you probably have an e-mail client. However, it could be easier to develop your own light-weight client to make sure your test conditions are under control. A network sniffer (like Ethereal) could be used to troubleshoot the software.
Do you feel confident on these topics? If not then I would sugest you start with a simpler project. POP3 is usually simpler than SMTP, and doesn't require relay. And you would act as a client instead of a server. Of course, POP3 is not what you asked for... 
I hope this helps,
Rilhas

I have a SDI application with 2-views. I can flick between the
2-views and there are many edit and check boxes on each view.
Its neat.
If I go to File/New, how can I make the data clear out of there?
Or, is there a way from CMainFrame to get a handle on CForm1 and
CForm2 which are both CFormViews and call the New() which clears
out all that data respectively? I cant figure out any resolution.
I tried lots of different things and nothing is working.
Please, any response any one can give me will be greatly appreciated.
Sincerely,
Danielle Brina

1) Get the message in the Document. Override CDocument functions:
virtual BOOL OnNewDocument( );
or
virtual void DeleteContents( );
(depending on which fits better into your situation)
2) tell your views about it.
POSITION pos = GetFirstViewPosition();
while (pos != NULL)
{
CView* pView = GetNextView(pos);
// you may have to cast to your view type here
pView->SomeFunctionYouAdd();
}
OR call:
UpdateAllViews(NULL, foo, bar);
where foo and bar are your application-specific hints (e.g. define bar==1 to mean "clear everything out"). Then watch for this in your view's OnUpdate function.
Best of Luck...

Hallo!
I created an ActiveX, which create an instance of another activeX at runtime and then determine the dispid with the name of a method (with the function: GetIDsOfNames(…)).
In the next step I can call this method with InvokeHelper(…).
So far, so good.
But if I want determine an EventId of a special Event with the name “CollectEvent”, I comes in trouble, because I have no plan.
Please help me to determine the eventid or give me a tip.
Thanks in advance.
Here the code for the invocation of a method:
<br />
....<br />
CWnd m_ControlWrapper;<br />
RECT rct = {0,0,5,50};<br />
<br />
BOOL bStat=FALSE;<br />
bStat= m_ControlWrapper.CreateControl(clsid, "Spectrometer", WS_CHILD, rct, this, 1212, NULL, FALSE, NULL);<br />
<br />
if (bStat == FALSE)<br />
{<br />
MessageBox ("Could not place control");<br />
return;<br />
}<br />
<br />
LPUNKNOWN pUnk = m_ControlWrapper.GetControlUnknown();<br />
<br />
LPDISPATCH pInterface = NULL;<br />
<br />
pUnk->QueryInterface(IID_IDispatch, (LPVOID*)&pInterface);<br />
<br />
<br />
CString CstrMethod = "STATUS"; <br />
BSTR BstrMethod = CstrMethod.AllocSysString();<br />
<br />
DISPID dispid; <br />
<br />
HRESULT hRet = pInterface->GetIDsOfNames(IID_NULL, &BstrMethod, 1, LOCALE_SYSTEM_DEFAULT, &dispid); <br />
<br />
m_ControlWrapper.InvokeHelper(dispid, DISPATCH_METHOD, VT_EMPTY, NULL, NULL);
<br />
....<br />
<br />
<br />

I am attempting to access a value that the user chooses in a Combo Box.
I use :
DWORD_PTR data = m_Combo.GetItemData(m_Combo.GetCurSel());
This returns 0 to me all the time. When i check the m_Combo.GetCurSel() value, it returns the correct index. but the m_Combo.GetItemData just returns 0 for the value at that index all the time.
Am i using this correctly first off and can anyone explain why this may be happening?

You don't use GetItemData to retrieve the text. Take a look at GetLBText[^] instead (GetItemData is for retrieving some data that you associated with the string).

Can you expand or give an example when you say that GetItemData is used to retrieve some data associated with the string?
Thanks,
