You really need to spend a lot more time reading the documentation on this interface before trying to implement it.

Please guide me.

Not sure why char[100]... ??? ...why not get the size first then allocate the array dynamically?

But, you can use the CString::GetBufferSetLength() (allows you to specify maximum size) method then just copy the contents of the buffer to the char[] using memcpy().

For Example i took char[100] As you mentioned i need to take the length of the string.
Thankyou Albert.

Use strcpy() or its wide character equivalent for the copy. For further information see here[^].

C++

LPSTR WideChar2MBCS( const CString& strCS )
{
	const UINT wLen = strCS.GetLength() + 1;
	UINT aLen = WideCharToMultiByte(CP_ACP,0,strCS,wLen,NULL,0,NULL,NULL);
	LPSTR lpa = new char[aLen];
	WideCharToMultiByte(CP_ACP,0,strCS,wLen,lpa,aLen,NULL,NULL);
	return lpa;
}

maybe this will help you.

I have a dll COM , I want to convert it to UNICODE.
I readed some documentations about this but I can't get what I should do to be sure that the conversion is done correctly or Not D'Oh! | :doh:

these are some remarks i have done in my code :

- Use of CString
- char changed by _TCHAR
- char*, LPSTR (Win32 data type) changed by LPTSTR
- const char*, LPCSTR (Win32 data type) changed by LPCTSTR
- USES_CONVERSION macro
- use of std::wstring instead of std::string
- change characters set of project to UNICODE

I don't know if it is sufficient or there are others things to do
And How can I check after conversion if it is Ok or Not.

Thanks for reply.

Richard MacCutchan8-Dec-11 0:28

You also need to make sure all your string literals ar changed from char to TCHAR with the _T() macro like this:

C++

const char* cp = "Ansi string";       // old style char literal
PCTSTR tcp = _T("TCHAR string"); // will generate Ansi or Unicode depending on project settings

After that, the only way to be certain you have it right is to desk check and test. There may be some free tools around to help verify it but I'm not aware of them; Google may help you.

sorry for that, I thought to click on 5, not to worry Wink | ;)

Just question please :
If I change the Option "Character Set" to "Use Unicode Character Set" and compile
If there is no error can we say that the version compiled without error is UNICODE now or not ?

Unfortunately no. The compiler should weed out most of the anomalies as it will reject a char where a WCHAR is required, but you still need to do all the things you mentioned in your original message and check the things I suggested. Your project is now probably Unicode but you must still check that you have not missed anything, and test it thoroughly. For example if you have something like:

C++

char* charP = "Hello, World";

that is perfectly legal code in a Unicode program but it may not be what you want.

What about :

unsigned char
unsigned char*
unsigned char const*
char **

in UNICODE ? By what we can replace them ?

Richard MacCutchan8-Dec-11 22:09

8-Dec-11 22:09

You would normally replace all of them by WCHAR (TCHAR defaults to WCHAR in a Unicode compilation). However, you first need to look at the context to see what the variables are being used for.

See an other problem please :

I have this table of char (NO UNICODE):
const char sm_S[8] = {9, 124, 119, 123, -14, 107, 111, -59};

and I want to work with it now on UNICODE : I convert it to
const TCHAR sm_S[8] = {9, 124, 119, 123, -14, 107, 111, -59};

But when I do like this :
TCHAR MyChar = sm_S[4]; this should be "-14" but I have an other value like "54265"

What do you think about this and have you idea to solve this problem?

Richard MacCutchan26-Dec-11 6:51

Firstly, stop using decimal numbers in your constants, use proper character constants. Secondly, as explained before Unicode is 16 bit unsigned so the value you see is quite correct.

Thnk you for repley.
About the first point : can you give me a link to table which contains the caracters with their numbers in decimal to change all them.?
Second : if this is correct have you idea to correct it ?

Use Character Map in Windows.
