How do i change a Unicode project to MBCS using Visual Studio 2005?
What i've tried:
I opened the properties dialog for my project and clicked on "C/C++->preprocessor".
When i clicked on the "..." button at the right hand side of the "preprocessor definitions" box, there is a checkbox saying "Inherit from parent or project defaults" and a box that lists the inherited values: "_AFXDLL,UNICODE,_UNICODE".
I unchecked this box and added "_AFXDLL" and "_MBCS" to the original list of preprocessor definitions.
The list now looks like this: "WIN32;WINDOWS;_DEBUG;_AFXDLL;_MBCS;$(NOINHERIT)"
Now when i compile, this error comes up:
msvcrtd.lib(wcrtexew.obj) : error LNK2019: unresolved external symbol _wWinMain@16 referenced in function ___tmainCRTStartup

You just needed to modify your project properties. Go to Configuration Properties and look at Project Defaults. Change the Character Set from Unicode to MBCS. If it's a new project, the question you should ask is, it's 2006, why aren't you using unicode?

Thanks. To answer your question, the main problem i was having is this:
CString tempbuf;
tempbuf = "Job number,";
file.Write((LPCTSTR)tempbuf,tempbuf.GetLength());
file.Close;
When i open the file, it has 'J o b n u' in it.
I was told to change my project settings to MBCS to solve this problem. Is there any other way?

That depends on what you are doing and why you consider this a problem.
file.Write((LPCTSTR) tempbuf, tempbuf.GetLength() * sizeof(TCHAR));
You would then have a file with a UTF16LE string that says "Job number,". (edit: for unicode builds, and a normal ascii string for your mbcs build)
Have you considered...
CStringA tempbuf;
tempbuf = "Job number,";
file.Write((LPCSTR)tempbuf,tempbuf.GetLength());
file.Close; ?

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.

when I add a project to the current workspace, a warning message box pops up which showes "A project with the same name as the selected project already exists in the current workspace.". But actually my workspace doesn't have the project. somebody knows why? and how to figure out...
It is urgent! I am waiting online.
I will appreciate your answer.

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).
Best,

codes:
<br />
m_imagelist1.Create(16, 16, ILC_COLOR32, 1, 1);<br />
CBitmap *bmp=new CBitmap;<br />
CString str;<br />
for(int i=1; i<109; i++)<br />
{<br />
str.Format("qqface\\%d_m.bmp", i);<br />
bmp->m_hObject=(HBITMAP)LoadImage<br />
(NULL, str, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);<br />
<br />
m_imagelist1.Add(bmp, RGB(0, 0, 0));<br />
m_treeQunimage.Add(bmp, RGB(0, 0, 0));<br />
<br />
}<br />
delete bmp; <br />
m_List1.SetImageList(&m_imagelist2, LVSIL_SMALL);<br />
m_List1.DeleteAllItems();<br />
int nItem;<br />
m_List1.SetIconSpacing(50, 50);<br />
for(int i=1; i<109; i++)<br />
{<br />
nItem=m_List1.InsertItem(2*i,"hello", i);<br />
}<br />

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

Just my interest for these common things

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.

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 />
SetTimer(3, 300, NULL);<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 !

Can anyone show me how to update, delete, and add a record in a MS access database using CRecordset class without inheriting it.
thanks...
---------------------------Life is simple, you just complicate things-----------------------

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++)
{
CDBVariant dbvarValue;
rs.GetFieldValue(nFieldIndex, dbvarValue);
}
rs.MoveNext();
}
rs.Close();
}
CATCH(CDBException, e)
{
e->ReportError();
}
AND_CATCH(CMemoryException, e)
{
e->ReportError();
}
END_CATCH

I need to add combobox into a listctrl as a subitem . how to do it?

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?
