Hey,

Sorry for my english, i don't speak very well. I have a problem , i want  send a string to a dll, but i just catch the first character in the .dll.

code :

code:

---

DLLIMPORT int ConectionLog (char * name)
{
   
    MessageBox (0, name, "Hi", MB_ICONINFORMATION);

}

---

code:

---

Interop.Call("msgplus.dll","ConectionLog", "hello"):

---

the 'string' passed from the script to the dll is widechars

code:

---

void DLL_EXPORT ConectionLog(WCHAR* sometext)
{
MessageBoxW(0, sometext, sometext, 0);
}

---

code:

---

to convert from unicode to ansi
void DLL_EXPORT SomeFunction(WCHAR* sometext)
{
int a = SysStringLen(sometext)+1;
char *ansistr = (char*)malloc;
WideCharToMultiByte(CP_ACP,
                        0,
                        sometext,
                        -1,
                        ansistr,
                        a,
                        NULL,
                        NULL);
//...use the strings, then free their memory:
//delete[] ansistr;
MessageBox(0, ansistr, "hello", 0);
free(ansistr);
}

---

thank's dramado, but i have a error she don't recognize the WCHAR type, i have include the wchar.h library but don't works...
