ERROR_PORT_ALREADY_OPEN is the error

This is probably a known problem with an easy workaround, but I haven`t seen it yet.
The problem is that I want to use code written in Visual C++ 6.0 in Visual Studio 2005. When I compile I get the following errors e.g.:
CString temp = pOrder->GetItemNr();<br />
pOrder->GetItemNr() returns a const char*
the error I got is:
error C2440: 'initializing' : cannot convert from 'const char *' to 'ATL::CStringT<basetype,stringtraits>'
What can I do so that this assignment works again? Anyone got any ideas?
Thanks for any help,
Davy

Modify this to,
CString temp = CString(pOrder->GetItemNr());

Isn`t there a better way?
In my old code I have a lot of places where a const char* is assigned into a CString sometimes directly sometimes as a parameter in a function. It`s a lot of places to do this.
Anyway thanks for your answer, I was affraid this might be the only solution...

What's the difference ? Both will call the same CString constructor so I don't see why it would work...
|

That's what I thought too originally, but doing this does make it work (compiler error is gone)
So I guess I`ll just have to do this for all the cases in my old code  .
Just came back from easter hollidays and now this mind-numbing job of putting CString () whereever the compiler complains... I need hollidays again

I thought that way initially. But, some how it is converting char* to wchar_t* in this case.

I certainly use this construct regularly in VS2005 and it works OK for me. What I have just checked is:
<br />
const char lpszFiles[] = "FileInfo"; <br />
<br />
CString str = lpszFiles;<br />
essentially the same.
You haven't got unicode defined have you?

I have actually.
It`s necessary because sometimes more than 1 language needs to be displayed.
In VC 6.0 the conversion from const char* to WCHAR* used by CString happened automatically, this doesn`t seem to be the case anymore

I don't get you. Do you need to write values into the registry?

If you are using an installer, look in its help for setting up registry values. If you are writing your own installer then you will have to write to the registry. There may be something about .reg files that can help you, but I have never used them for this.

If you used DoModel() API, for the child dialog to show it, then the child dialog is model.Instead if you used other API to show the dialog,say, ShowWindow(..),then its modeless

By default, the escape key triggers the OnCancel() event of a modal dialog. You must override the OnCancel function in your dialog class. Example from MSDN:
void MyDialog::OnCancel()
{
if ( AfxMessageBox("Are you sure you want to abort the changes?",
MB_YESNO) == IDNO )
return;
CDialog::OnCancel();
}
|

OnCancel is not only called by hitting ESC key, also called by closing dialog box, for settling this, I think u may overwrite CDialog::PreTranslateMessage funcion like this.
BOOL CdlgtestDlg::PreTranslateMessage(MSG* pMsg)
{
if(pMsg->hwnd == m_hWnd || ::IsChild(m_hWnd,pMsg->hwnd) && (pMsg->message == WM_KEYDOWN || pMsg->message == WM_KEYUP))
{
if(pMsg->wParam == VK_ESCAPE)
return TRUE;
}
return CDialog::PreTranslateMessage(pMsg);
}
