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

In fact it will not compile if UNICODE is defined.

CString, strcpy() are not handling unicode...

use CStringW and wcscpy_s() instead, and of course, when using literals, type them with a prepending L

   The data is not Unicode until the call to mbstowcs(...) at which point buf (a Unicode/wide character buffer) should contain Unicode data. At that point, the CString and strcpy(...) are no longer involved.

   Most ANSI/MBCS applications are capable of handling Unicode data and vice-versa simpy by using/omitting the L prefix on strings to indicate a wide/narrow string and using the appropriate W/A suffix 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...

   Peace!

   Assuming that pc_char is a suitable char buffer, the conversion to Unicode looks OK from here.

   I would try a few things...

     1: Remove the CString usage - 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 );
<code>// HWND hWndView = ::GetDlgItem( hWnd, IDC_VIEW );
//::SetWindowTextW( hWndView, wcaBuf );</code>

     2: Make sure that the conversion to Unicode was successful by checking the return value from mbstowcs(...)
     3: Check the return value of SetDlgItemTextW(...), and maybe try using SetWindowTextW(...) by first obtaining the HWND of the IDC_VIEW control.
     4: This may be a stupid question, but are you sure that IDC_VIEW is a "text-able" control (edit, button, static/label, drop-list combobox)?

   Peace!

Wow. Alot of discussion and 1-voting on this thread Smile | :)

Isn't this sufficient?

CStringW str=L"Name";
SetDlgItemTextW(hWnd,IDC_VIEW,str);

you have to subclass that CFileDialog class, and OnInitDialog of that function you can perform your required function!

This can be done in the dialog's OnInitDialog() method (if using MFC), or in response to the WM_INITDIALOG message.

How to make a lzh file manually!

15-Jul-07 22:15

I try to add lzh header and lzh extend header before a file in order to make a lzh file manually. According to lzh format, I use "-ld0-" and level 0x01 so i can avoid to write compress codes. But after i add this header to a file, there is wrong when i open it with winrar. The Message is that file was damanged. I think the problem maybe take place in two ways:
1. I don't know hwo to get the checksum in lzh header.
2. CRC-16 maybe is wrong, i just copy the code from internet.

Can someone give me advice in this topic, some demonstrated codes are best.
Thanks.

why does my activex control register unsuccessfully?

I've tested in ActiveX test container which runs very well,when user have register such control,it runs quickly.But when I've use web to automatically register this control,it always represents red x on web.By the way,I use MFC activeX with MFC share DLL and open all the access right for activex control,meanwhile, I've add the server ip to trusted zone.Can somebody give me a help?

I think u r using a cab file for downloading the activex.

Is your control getting downloaded, jus check it in

Tools->Internet Options->General->View Objects in ur browser

This is the place your ActiveX once downloaded gets displayed.

UnRegister previous ActiveX registered , u can use regsvr32 -u cmd

ActiveX controls must exist on the machine your browser resides on (Downloading if necessary if the "codebase=" contains a valid path to the cab when not already installed on users machine). ActiveX controls, by default, have access to anything an executable has access to so when running them from within a browser, security restrictions kick in and protect people from running ActiveX controls that are not declared "Safe for scripting" in the registry. The control can also implement a specific interface to be "safe for scripting" if the programmer desires.

If you run the .htm file with an .hta extension on your local machine, browser security should not restrict you.

If this is not an option, then you will likely need to research the security restriction for ActiveX controls in browser based environments. Be forewarned, ActiveX controls are easy security breaches so their value in the web world was quickly diminished in the late 90's.
