Not that I know of, unless you are using the .NET framework.

Then check out the Double.IsInfinity() method.

Hi All,
In VS 6 I copy data from a custom control on a dialog using my own clipboard management (see code below) and would like to paste it into a CEdit on the same dialog. I believe I am getting it to the clipboard correctly, in CF_TEXT format because I can paste the text into WordPad or Notepad just fine. I am unable, however, to paste my clipboard contents to the CEdit either with the CEdit context menu or Ctrl+V. Making this all the more confusing is that if I copy text from Wordpad, which presumably is in CF_TEXT format, I am able to paste into the standard CEdit just fine.
Any ideas would be greatly appreaciated!
Thanks,
Doug

CString strData;
m_list.GetText(m_list.GetCurSel(),strData); m_list is the Control variable of the CListBox Control.

I try to share .pch (precompiled header files) across my library (more than 50) but i failed.
Using VC+ 6.0 is possible to share the .pch file reducing compilation time but when i try this in VC+2005 i ave found a lot of problems...
Can anyone help me?
Tanks and sorry for the poor english...

I suppose you could in theory, assuming the files comprising each project were the same, but are you sure you want to? Why not just let the .pch file get built once for each project and be done with it? Your apt to spend more time trying to 'share' the file than you would just building it for each project.

I don't understand what the problem is?
As the parent window size changes you have to calculate what "equal" is and then adjust the components (views, splitters, whatever) that are required, right?

Hi,
I have developed a small application, using ODBC with Access.
I then ported my tables to SQL Server 2000.
When I Open() a Recordset, all my tables are opened in read/write-mode, except two tables, that I use all the time.
These two tables differ from the other tables only, that they contain a CTime field.
Here is my code
Favorit.m_strFilter="Username='"+myUser+"' AND Dokument='"+Number+"'";
Favorit.Open();
if(!Favorit.IsBOF())
{
Favorit.MoveFirst();
Favorit.Edit();
}
else
{
Favorit.AddNew();
Favorit.m_User=myUser;
Favorit.m_Dokument=Number;
Favorit.SetFieldNull(&(Favorit.m_Gelesen));
}
Favorit.m_Favorit=bChecked;
Favorit.Update();
Favorit.Close();
When AddNew() I get the message, that this record is readonly. It works well in Access, but AddNew() throws an exception, that this record is readonly. Why? And how can I repair it?

What does CRecordset::CanUpdate() indicate?
"The largest fire starts but with the smallest spark." - David Crow

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?

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.
