error C2440: '=' : cannot convert from 'char *' to 'ACHAR *'

[DWhiteley]

Guys,

I'm converting an old C++ project to ObjectARX 2013 & then on later to 2016 from 2004. (i'm assuming Visual Teefy might help me out in 2013).

This bit of code has got me stuck:

#define START_STR(rb,str) rb = ads_newrb(RTSTR);rb->resval.rstring = cpCopystr(str)

 START_STR(rbMake, _COPY);

I'm getting this error:

Error 5 error C2440: '=' : cannot convert from 'char *' to 'ACHAR *'

I'm assuming it's because of the UNICODE changes.

Can anyone help me out on this please?

You have to provide code of cpCopystr. I think this function have to return ACHAR * instead of char *

Also you have to use in code:

START_STR(rbMake, L"_COPY");

[DWhiteley]

Here you go:



char *

cpCopystr(char *str)

{

char *temp;

temp = (char *)malloc((unsigned) (strlen(str) + 1));

if (temp == NULL) {

#ifdef NON_ADS

printf("Out of memory in cpCopystr()");

abort();

#else

acrx_abort("Out of memory in cpCopystr()");

#endif

}

strcpy(temp, str);

return(temp);





Regards



Dave

What about next code:

#define START_STR(rb,str) (rb = acutBuildList(RTSTR, str))
resbuf *rbStart = NULL;
START_STR(rbStart, L"_COPY"); 

P.S.: I do not know what is _COPY in your code.  I hope it is a string like "_COPY"

Hi Alexander,

_COPY is defined as:

#define _COPY          "_.COPY\0"

do I need to alter this to  _T("_.COPY\0") ?

Yes. Or L"_.COPY\0"
