QAxWidget, How to close Acrobat pdf Reader AcroRd32.exe - the process who survives.

[VlJE]

Hi! I load the acrobat reader 8 ActiveX Control:
ui.axWidget->setControl("{ca8a9780-280d-11cf-a24d-444553540000}");
QVariant qvRc=ui.axWidget->dynamicCall("LoadFile(const QString&)", fi.absoluteFilePath());

In the destructor:
ui.axWidget->clear();

The problem:
If I close my dialog, the process AcroRd32.exe survives and complains if I for example end my windows XP session.

Try

dumpcpp {ca8a9780-280d-11cf-a24d-444553540000} -o acropdf
and see if there's a method for cleaning up.. Oh, and does the widget get properly destructed?

Dumpcpp works and produces .cpp and .h files, thank You.
There is nothing similar (for me) to the cleaning up method.
If I put following lines one direct after other:
ui.axWidget->dynamicCall("LoadFile(constQString&)",path);
ui.axWidget->clear();
, so I see no PDF Document in my widget, the process AcroRd32.exe remains in memory after I finish the application.

Btw, this works for me:


#include <QtGui>
#include <ActiveQt>
#include "acropdf.h"

int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QString file = QFileDialog::getOpenFileName();
if (file.isNull())
return 0;

AcroPDFLib::AcroPDF pdf;
pdf.LoadFile(file);
pdf.show();
return app.exec();
}

Where acropdf.h and acropdf.cpp were generated by dumpcpp. I can see AcroRd32.exe starting up, and I can see it quitting a while after the window is closed.

In the Destructor:

QProcess pPdfviewer(ui.axWidget);
pPdfviewer.kill();

Hope this helps...:cool:
