If I could specify the folder where to create it, it would be great!

Thanks!

Making a DLL

Hello
I need to write a DLL for some functions that I have which depend on a separate lib file.
when i write a short test program that uses the functions as is and link against the lib file, everything works great. But when i take the same functions and put them in a DLL, it doesn't work (i get some unresolved references to any function that I use from the lib file).
Am i supposed to do anything special to get it to recognize the functions from the lib?

thanks for your time.

effectively, there are some things to get done for a DLL to work properly.

you should start by reading this[^] article...

yeah i already know that bit
when i have regular functions that don't depend on the library (the one that I didn't write) the dll builds just fine
it's when i use the library's functions in my dll that i get the linking errors.

You haven't specified what type of DLL you're using or how you are linking
and/or binding to the DLL at runtime so it's difficult to give a specific answer.

I do know you will find links to a solution here[^]

If I had to guess, I'd say you need to link your application project
to the link library produces by a build of the DLL project, but again,
this is a wild guess since you gave no specifics.

I am getting a exception while running in the debugger. It happens inside a memcpy and VS 2003 C++ stops the app and opens the assembly code for the memcpy. Is there anyway to find out which memcpy in my code cause this problem.

Problem with DatePicker

Hi Friends
I am not able to get the Selected Date from the DatePicker. It is showing me the Current DateTime always.

I am new with VC++.
//Initializing
, m_Date( CTime::GetCurrentTime())

DDX_DateTimeCtrl(pDX, IDC_DATE, m_Date);

And then i am Changing the Date in DatePicker, and on Button Click Event,
i have the below instruction, where i need the Selected Date but instead it is showing me CurrentDateTime()

SELECT Polhsh_ID FROM Polhsh WHERE Installation_ID = %d AND Pelaths_ID = %d AND ActionType = '%s'AND Hmeromhnia= #%s# "), Installation_ID, m_Promhtheytes.GetItemData( m_Promhtheytes.GetCurSel()), ActionType, m_Date.Format( _T("%Y/%m/%d")) );

But i am always getting the Current DateTime.

I know it must be something simple, But i am completely new with VC++.

I hope if anybody gets time, give me some help.

Thanks

Cheers

Menon

See UpdateData()[^]

Also if your beginning you should be using a book or tutorials. If they have not covered UpdateData then they aren't any good so find another.

This works fine for me:

void CMyDlg::DoDataExchange(CDataExchange* pDX)
{
    CDialog::DoDataExchange(pDX);
    //{{AFX_DATA_MAP(CMyDlg)
    DDX_Control(pDX, IDC_DATETIMEPICKER1, m_date); // m_date is CDateTimeCtrl object
    //}}AFX_DATA_MAP
}
 
BEGIN_MESSAGE_MAP(CMyDlg, CDialog)
    //{{AFX_MSG_MAP(CDbcDlg)
    ON_NOTIFY(DTN_DATETIMECHANGE, IDC_DATETIMEPICKER1, OnChangeDateTimePicker)
    //}}AFX_MSG_MAP
END_MESSAGE_MAP()
 
void CMyDlg::OnChangeDateTimePicker(NMHDR* pNMHDR, LRESULT* pResult) 
{
    COleDateTime t;
    m_date.GetTime(t);
    TRACE("%s\n", t.Format("%Y/%m/%d"));
	
    *pResult = 0;
}

Note there is no UpdateData() call.

It's not necessary when you use control variables (e.g., CDateTimeCtrl instead of CTime).

CAsyncSocket Prob

Hi,

I am Using VC++6.0. I created a little demo Proggy, that contains a Server and a Client Class, derived from CAsyncSocket and everything works fine so far.

But now I transferred the client class into another App and it doesn't work.

I have this kind of code:

<br />
CMyAsnycClient Client<br />
<br />
Client.Create();<br />
Client.Connect("127.0.0.1", 23);<br />

My Test Proggy Server Gets the
OnAccept(),
and calls
Server.Accept(AcceptedSocket);

Everything fine so far.

But now my Client should get
OnConnect()
and it doesn't, where it does in my Test Proggy. Where could be a difference, when I use the same class and the same pieces of code?
