Hi Freaks

For char* in a struct I got a solution, thanks to Arthur at the u.B.G at Hamburg/Germany !

Windows allready do have a “wrapper”-DLL, called shlwapi.dll
In the DLL there many, many function. One of them is “StrDup” (StrDupA and StrDupW)

PSTR StrDupA( PCSTR pszSrch );

Input is a (const) string, i.e a normal “basis string” in UnifAce signature
the function will copy the string onto a static heap and return the address
This address can the pass to any DLL, direct or in a struct.

Don’t forget to free the memory after the job is done:

LocalFree( HLOCAL hMem );
