Load Symbian DLL or use function from DLL in Qt App

[newbis60]

Hi All,

This is my 2nd day with Qt development and eventually it has became tough for me to migrate from Carbide C++ to Qt for Symbian.. need your help..

I have a Symbian C++ DLL developed using Carbide C++ for sending SMS.. I want to use this DLL in a Qt App.. say a button push on Qt App triggers SendL() in DLL and sends SMS.. things I am stuck with are:

1. How do I connect to or load a Symbian DLL in Qt App..

LIBS += c:/Qt/4.7.0/lib/SmsDll.lib in Qt .pro or
symbian:LIBS += -lSmsDll

none of the above is working for me and I cannot connect or load SMS.. I have even tried loading an existing header file from Carbide work space which resulted in header file not found error..

HEADERS += mainwindow.h \
../../../Symbian/Carbide/WorkSpace/Dll/inc/SMS_DLL.h

2. Can I use the same header file which i have used in Carbide C++ in Qt as well.. reason is when I just create new header file of the Symbian LIB Header file within the Qt App.. I can only see lot of errors as I can see that Qt does't understand any of the Symbian header files or libraries or datatypes.. DO I NEED TO CREATE A NEW HEADER FILE OF THE LIB FILE in Qt..

3. How can i invoke SendL() function which eventually is in DLL from my push button or atleast from Main() of Qt.. for Dynamic loading..

void MainWindow:n_SendSmsButton_clicked()
{
QLibrary myLib("SmsDll");
typedef void (*MyPrototype)();
myLib.load();
if(myLib.isLoaded())//this succeeds
{
MyPrototype myFunction = (MyPrototype) myLib.resolve("SendL");
if (myFunction)
{
.....SendL(arguments);.............
}
}

I need to pass arguments Phone Number and Message to SendL()..

I am a bit lost.. can you plz help me with an example or suggestions of loading and using a Symbian DLL in a Qt App..

Thank you very much..

P.S. If the whole message is absolutely crap plz forgive me as this eventually is my 2nd day with Qt...
