What does CRecordset::CanUpdate() indicate?

CanUpdate() returns FALSE right after Open()
I also checked the rights on my SQL-Server but they seem to be ok. All other tables work well even when Update() is called.
I also dropped the table and created it new. Same effect

Nope,
it's just a plain table.
DBFavoriten::DBFavoriten(CDatabase* pdb)
: CRecordset(pdb)
{
m_Dokument = _T("");
m_User = _T("");
m_Favorit = 0;
m_Gelesen=CTime(NULL);
m_nFields = 4;
m_nDefaultType = dynaset;
}
CString DBFavoriten::GetDefaultConnect()
{
return _T("ODBC;DSN=QM-DB");
}
CString DBFavoriten::GetDefaultSQL()
{
return _T("[Gelesen]");
}
void DBFavoriten::DoFieldExchange(CFieldExchange* pFX)
{
pFX->SetFieldType(CFieldExchange::outputColumn);
RFX_Text(pFX, _T("[Dokument]"), m_Dokument);
RFX_Text(pFX, _T("[Username]"), m_User);
RFX_Long(pFX, _T("[Favorit]"), m_Favorit);
RFX_Date(pFX, _T("[Gelesen]"), m_Gelesen);
}

Is the QM-DB DSN configured as read-only?
"The largest fire starts but with the smallest spark." - David Crow

No,
as I said before, my database contains about 7 tables. All of them work perfectly well, except the one mentioned.
I think, maybe it's the CTime. It's the only table, that contains this datafield. I will try to replace CTime with long and write some conversion-members.

I doubt it. I've had several record sets with CTime member variables. They update fine.

Yes,
I have another table without CTime and this table is also opened read-only One I haven't tried before.
I wrote a small application, that does nothing else, except connecting to my SQl-Server database and appending a record. And it worked. The record was appended, but when I tried to delete this record again, SQL-Server told me something about relations and deleting more than one line. So I have some garbage-data in my database, that can not be deleted again. I have to drop the complete table.
I think I quit it and try to share my access-file on a fileserver. It's awful, but I don't know, why SQL-Server opens some of my tables read-only. I need this application by the end of the month and I thought, well it runs on access, now I migrate access to SQL-Server and everything is fine. Bad luck, haven't thought about Microsoft
By the way, when reading from the access-file it is much faster than reading from SQL-Server, which is really strange.

Strange things happen.
I created my SQL-Server database completely new and suddenly my tables work now.
At least most of them. Two tables are still readonly, but the rest is working. So I think, it's not a problem of my application, it's a problem of SQl-Server

I'm going completely nuts.
I changed my connection type from dynaset to snapshot and suddenly it works. Everything works as expected and even faster, too.
Now I have to change my sources a little bit to support a snapshot connection and I am finished with my project.
Thanks for all your help

For example
GetLastError()==ERROR_IO_PENDING
WSAGetLastError()==WSA_IO_PENDING
Which one should I use in socket programming?

WSAGetLastError, since it is Windows Sockets 2 specific.

Theoretically speaking, when using sockets, you should use the WSA calls. Practically speaking, they end up going to the same place (that is, WSAGetLastError simply returns the a call to GetLastError and the WSA values are pretty much the same as their normal win32 API equivalents). You should NOT assume that will always be the case, however.

Do you mean, practically, I could use either one?
But the two MACRO for error no. is differenct.

Yes, practically, you could use either one (at the moment). However, if Microsoft decides to change the behavior of WSAGetLastError, you'd be up the creek if you used GetLastError instead. While there isn't a high probability of that, in practice you should use WSAGetLastError when dealing with sockets. Not to mention that it makes your code consistent with the other socket calls (for someone else trying to read your code).

I see
win32
#define WSA_IO_PENDING (ERROR_IO_PENDING)
win16
#define wSA_IO_PENDING (WSAEWOULDBLOCK)

Can you add one include:

Hmm... It looks ok to me...
Would you please include this way:
#include "stdafx.h"

#include "DigitActions.h"
#include <list>
#include <string> And change the line as below to explicitly specify the scope.
