ActiveX EDRE uDAQ from Eagle Technologies

[BenDUV]

Hi All
I'm trying to get my uDAQlite from Eagle technologies going.
I have installed the EDRE drivers and ActiveX components on my machine (win 7 pro)
I can see and add the ActiveX controls to my form. So I know QT can see the ActiveX control. I have not added to the form.
I have done the following
in my .pro```
QT += core gui
axcontainer

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

LIBS += -LD:\Projects\Trewfit\AVP_TEST_BENCH\AVP_TEST_BENCH\Include
LIBS += -ledrapi

INCLUDEPATH += $$PWD/../Include/
DEPENDPATH += $$PWD/../Include/

TARGET = TestBench
TEMPLATE = app

SOURCES += main.cpp
mainwindow.cpp
channeloutputsettings.cpp
channeloutput.cpp
udaq.cpp

HEADERS += mainwindow.h
channeloutputsettings.h
channeloutput.h
udaq.h
D:/Projects/Trewfit/AVP_TEST_BENCH/AVP_TEST_BENCH/Include/edrapi.h \

D:/Projects/Trewfit/AVP_TEST_BENCH/AVP_TEST_BENCH/Include/errors.h \

D:/Projects/Trewfit/AVP_TEST_BENCH/AVP_TEST_BENCH/Include/query.h \

D:/Projects/Trewfit/AVP_TEST_BENCH/AVP_TEST_BENCH/build-TestBench2-Desktop_Qt_5_7_0_MinGW_32bit-Debug/ui_mainwindow.h

FORMS += mainwindow.ui

My class uDaq.c if have

uDAQ::uDAQ()
{
uDAQliteUTILS = new QAxWidget; //! \brief uDAQliteUTILS = {8AA34F85-95C9-11D3-8EB6-00C0DF2247CA}
uDAQliteAdX = new QAxWidget; //! \brief uDAQliteAdX = {450019E5-96C3-11D3-8EB6-00C0DF2247CA}
uDAQliteDaX = new QAxWidget; //! \brief uDAQliteDaX = {73E1B965-96BB-11D3-8EB6-00C0DF2247CA}

uDAQliteUTILS->setControl("{8AA34F85-95C9-11D3-8EB6-00C0DF2247CA}");
uDAQliteAdX->setControl  ("{450019E5-96C3-11D3-8EB6-00C0DF2247CA}");
uDAQliteDaX->setControl  ("{73E1B965-96BB-11D3-8EB6-00C0DF2247CA}");

}

in my uDaq.h I have

class uDAQ
{
public:
QAxWidget* GetD2AOCX();
QAxWidget* GetA2DOCX();
QAxWidget* GetUtilsOCX();
static uDAQ* getInstance();
long getserial();

private:
uDAQ();
static uDAQ* onlyInstance;
QAxWidget *uDAQliteUTILS;
QAxWidget *uDAQliteDaX;
QAxWidget *uDAQliteAdX;
long serialnumber;

};

I'm trying to get the serial number of the device
according to the documentation I can use this.

QVariant test;

test = uDAQliteUTILS->dynamicCall("EDRE_Query(int,int,int)",0,15,0);

but test is always invalid.
What am I missing?
Kind regards
