[quote author="kitten" date="1316008652"]it work correctly
i use dumpcpp to use it , it works correctly and this functions work correctly too
but when i send a text of other languages like persian to this dll it show me ???? in replace of my text
[/quote]What work correctly ? When your program crashes ?
Also for persian and arabic conversion, maybe "PAText wiki":http://developer.qt.nokia.com/wiki/QPlugs_PAText_Add_Persian_and_Arabic_support_to_WindowsCE_Mobile_applications will help you -

this is my function i want to use it
@
inline bool CZKEM::WriteLCD(int Row, int Col, const QString& Text){
bool qax_result;
QString st("mil");
BSTR test = SysAllocString(st.utf16());
_bstr_t te(test);
void _a[] = {(void)&qax_result, (void*)&Row, (void*)&Col, (void*)test};
qt_metacall(QMetaObject::InvokeMetaMethod, 244, _a);
SysFreeString(test);
return qax_result;
}
@and this is a function generated with dumpcpp
@inline bool CZKEM::WriteLCD(int Row, int Col, const QString& Text)
{
bool qax_result;
void _a[] = {(void)&qax_result, (void*)&Row, (void*)&Col, (void*)&Text};
qt_metacall(QMetaObject::InvokeMetaMethod, 244, _a);
return qax_result;
}@i am changing the function
