Please save the following code as C file, it works. Use with VFP declare integer ConvertTime IN timeconv.dll String @Buffer Buffer = space(64) ? ConvertTime(@Buffer) ? Buffer #define STRICT #include #include BOOL WINAPI DllMain(HANDLE hInst, ULONG ulReason, LPVOID pReserved) { switch (ulReason) { case DLL_PROCESS_ATTACH: break; case DLL_PROCESS_DETACH: break; default: break; } return (TRUE); } int WINAPI ConvertTime(LPSTR pBuffer) { int iResult = -1; struct tm *newtime; time_t aclock; aclock = time(NULL); // 8067157205 is invalid, localtime() returns NULL pointer if (pBuffer && (newtime = localtime(&aclock))) { lstrcpy(pBuffer, asctime(newtime)); iResult = lstrlen(pBuffer); } return (iResult); } Winfried
