SetDlgItemTextW problem
-
I am using VC++ and want to display UNICODE String on a Dialog box Doing it like this : CString str="Name"; wchar_t buf[255]; strcpy(pc_char1,str); mbstowcs(buf,pc_char1,str.GetLength()+1); SetDlgItemTextW(hWnd,IDC_VIEW,buf); and HWND hWnd is declared in .h File The problem is even though code compiles fine but nothing gets displayed.

CString,strcpy()are not handling unicode... useCStringWandwcscpy_s()instead, and of course, when using literals, type them with a prepending**L**

CString str=_T("name"); SetDlgItemText(IDC_BTN_RESET,str);works fine :) does that solve it?sonsam wrote:
CString str=_T("name");
no. this instead :
CString str = L"Name";

I guess UNICODE is not defined else

CString str="Name";
will not compile.

:confused: sure it will, and it does ! but it doesn't work properly if UNICODE and _UNICODE are not defined...

The data is not Unicode until the call to
mbstowcs(...)at which pointbuf(a Unicode/wide character buffer) should contain Unicode data. At that point, theCStringandstrcpy(...)are no longer involved. Most ANSI/MBCS applications are capable of handling Unicode data and vice-versa simpy by using/omitting theLprefix on strings to indicate a wide/narrow string and using the appropriateW/Asuffix on the Win32 API. Your application configuration (UNICODE#defined or not) mostly indicates the default character width and version of the Win32 API to link with. There is something else going on...

Assuming that
pc_charis a suitablecharbuffer, the conversion to Unicode looks OK from here. I would try a few things... 1: Remove theCStringusage - it is not necessary and only adds time and another point for exception handling.LPCTSTR pcData = "Name";
wchar_t wcaBuf[255];::mbstowcs( wcaBuf, cpData, ::_tcslen( cpData ) );
::SetDlgItemTextW( hWnd, IDC_VIEW , wcaBuf );
// HWND hWndView = ::GetDlgItem( hWnd, IDC_VIEW ); //::SetWindowTextW( hWndView, wcaBuf );2: Make sure that the conversion to Unicode was successful by checking the return value from
mbstowcs(...)3: Check the return value ofSetDlgItemTextW(...), and maybe try usingSetWindowTextW(...)by first obtaining theHWNDof theIDC_VIEWcontrol. 4: This may be a stupid question, but are you sure thatIDC_VIEWis a "text-able" control (edit, button, static/label, drop-list combobox)?

Wow. Alot of discussion and 1-voting on this thread :) Isn't this sufficient? CStringW str=L"Name"; SetDlgItemTextW(hWnd,IDC_VIEW,str);

or this CStringW str("Name"); SetDlgItemTextW(hWnd,IDC_VIEW,str);

Or this:

:P Peace!
