Re: Change a Unicode project to MBCS using VS2005

26-Jun-06 10:28

1 more question... For VS2005, whenever i'm working with a string say,

AfxMessageBox(_T("Something"));

I would have to put a '_T' before the string. Is there an easier way to work with strings without having to use '_T'?

_T is a macro that resolves to a unicode string on unicode builds (_UNICODE/UNICODE defined) and mbcs on mbcs builds. Eg. _T("Something") is L"Something" on unicode builds and "Something" on mbcs builds (You put L in front of a string to indicate a unicode string). It would be preferable to just get used to using the _T macro and all the TCHAR functions.

Two options:
1) Manually modify project files (.dsw, .dsp, .rc, etc)
2) Create a new project and copy over source files from the old project. Be sure to use the same project settings (easier to say than to do).

I think you need to check your code But see m_imagelist1.Replace(0,LoadIcon(AfxGetInstanceHandle(),(LPCTSTR)IDR_MAINFRAME)); maybe it is some helpful to you

LVITEM item = {0};
item.mask = LVIF_IMAGE;
item.iItem = /* item's index here */;
item.iImage = /* image index here */;
m_List1.SetItem(&item);

The parent window receives a NM_DBLCLK notification, and the message LPARAM points to an NMITEMACTIVATE that tells you which item was clicked, if any.

Help! How to add combobox into a listctrl ?

26-Jun-06 5:50

Thank you very much!
I have done it following:

Item=new LVITEM;<br />
	oldImage=faceNO[m_nCurrentSel/2]-1;<br />
	Item->mask=LVIF_IMAGE	;<br />
	Item->iItem=m_nCurrentSel ;<br />
	nHop=0;<br />
<br />
	SetTimer(2, 400, NULL);<br />
	// hidden<br />
	SetTimer(3, 300, NULL);<br />
	// display

////////////////////////////////////////////////////<br />
if(nIDEvent==2)<br />
	{<br />
		if(nHop++>4)<br />
		{<br />
			KillTimer(2);<br />
			KillTimer(3);<br />
			return;<br />
		}<br />
		Item->iImage=-1;<br />
		m_List1.SetItem(Item);<br />
		m_List1.RedrawItems(Item->iItem, Item->iItem);<br />
	}<br />
	else if(nIDEvent==3)<br />
	{<br />
		Item->iImage=oldImage;<br />
		m_List1.SetItem(Item);<br />
		m_List1.RedrawItems(Item->iItem, Item->iItem);<br />
	}

,but feel the effect is not comfortable!
My old idea is to make an icon visible and hidden by turns
it's so uncomfortable, I can see the icon twinkling!
How to prevent this happen?

Hope for some helps !

CRecordset problem

Can anyone show me how to update, delete, and add a record in a MS access database using CRecordset class without inheriting it.

thanks...

For UPDATE, DELETE, and INSERT statements you don't need even CRecordset.
Can directly call CDatabase::ExecuteSQL, like for example:

class CFoo
{
// ...
   CDatabase m_db;
};
void CFoo::SomewhereInSpace()
{
   TRY
   {
      m_db.ExecuteSQL(_T("UPDATE Cats SET Name='Kitty' ")
                      _T("WHERE OwnerName='James'"));
   }
   CATCH(CDBException, e)
   {
      e->ReportError();
   }
   END_CATCH
}

... and if you want to use CRecordset (for SELECT statements, no way, you must do it), instantiate a CRecordset object (no need to derive) the call CRecordset::Open, and so on.

See example below

TRY
{
   CRecordset rs(&m_db);
   rs.Open(CRecordset::forwardOnly,
           _T("SELECT Name, OwnerName FROM Cats"));
   while(!rs.IsEOF())
   {
      const int nFieldsCount = rs.GetODBCFieldCount();
      for(int nFieldIndex = 0; nFieldIndex < nFieldsCount; nFieldIndex++)
      {
         // next field
         CDBVariant dbvarValue;
         rs.GetFieldValue(nFieldIndex, dbvarValue);
         // enjoy of field value...
      }
      rs.MoveNext(); // next record set row
   }
   rs.Close();
}
CATCH(CDBException, e)
{
   e->ReportError(); // see what's going wrong
}
AND_CATCH(CMemoryException, e)
{
   e->ReportError(); // see what's going wrong
}
END_CATCH

visual studio 2005 problem with converting strings

cv_k3n24-Jun-06 19:45

Re: visual studio 2005 problem with converting strings [modified]

24-Jun-06 19:45

Hi, i just upgraded from visual studio 6 to visual studio 2005. The problem here is that i get this error message whenever i try to create a simple AfxMessageBox.

"error C2665: 'AfxMessageBox' : none of the 2 overloads could convert all the argument types"

I realise that if i do it like this,

AfxMessageBox((CString)"Something");

it will work. In the previous version there is no need for the '(CString)' part. Is it really meant to be like this in this new version or am i missing something here?

Stephen Hewitt24-Jun-06 19:50

Don't go around casting. Use this:

AfxMessageBox(_T("Something"));

The _T (from <tchar.h> ) is a macro which makes the string MBCS or UNICODE depending on what your build is targeting.
