[kim]

need a help regarding following matter.

this is the function that I'm going to call using dynamicCall();->getContourLine(double x1, double y1, double x2, double y2, VARIANT* strPTs)

ui.axWidget->dynamicCall("getContourLine(double x1, double y1, double x2, double y2, VARIANT* strPTs)",202916,362432,200191,366623,"5th parameter here");

But I cant get value which return from VARIANT* strPTs since unable to define 5th parameter correctly . if anyone Can give a solution, more than appreciated!! Thank u very much!

According to http://doc.qt.io/qt-5/qaxbase.html you should be able to use a reference to a QVariant

QVariant strPTs;
ui.axWidget->dynamicCall(
    "getContourLine(double x1, double y1, double x2, double y2, VARIANT*strPTs)",
                    202916,    362432,    200191,    366623,    strPTs);

QVariant strPTs;
ui.axWidget->dynamicCall(
    "getContourLine(double x1, double y1, double x2, double y2, VARIANT*strPTs)",
                    202916,    362432,    200191,    366623,    strPTs);

Thank you @ChrisW67.

I tried it. But I get the same result which "CXX0030: Error: expression cannot be evaluated". When I do it with MFC I get the correct result as in the image.result with MFC.jpg. Please help! thank you!
