TCHAR*

[Pyramus]

Function(TCHAR *szRet)

I'm trying to use the above example function by doing:

TCHAR buf [1024];
Function(&buf[0]);

I get this compilation error:

cannot convert parameter 1 from 'char *' to 'unsigned short *'

Any ideas?

Your syntax is wrong.

Change Function(&buf[0]) to Function(buf)

If I do that I get:

Cannot convert parameter 1 from 'char [1024]' to 'unsigned short *'

Do you have UNICODE defined? And if so, did you do it in the file or in the project settings?

Your function

Function(TCHAR* szRet);

should have NO problem with the call

Function(&buf[0]);
or
Function(buf);

One more question, do you link to multiple projects?

UNICODE isn't defined. Should this matter?

 

[Zyrenthian]

Yes. For some reason, in one spot it sounds like UNICODE is defined. There exists a precomplier directive as follows

#ifdef _UNICODE
typedef TCHAR char;
#else
typedef TCHAR wchar_t;
#endif

put a #undef _UNICODE before your function and see if you can get it to compile. This should NOT be left in but it will let you know if _UNICODE has been defined in your project.

Actually, thinking about it, most likely you are using "precompiled headers" and the #undef MAY not work.

Go into project settings for all your projects, click on the C++ tab and select "Preprocessor" from the dropdown list. Make sure _UNICODE is not in the list of "Preprocessor Definitions"

I have never used it but "Undefined Symbols" could get _UNICODE added and have the same effect I THINK

You got me on the right lines with the UNICODE- it turns out the function I'm calling takes a WCHAR, not a TCHAR. I'm now going to go slap my colleague who wrote this function

LOL!!! Smack him once for me too
