How to fix error code code: 0x8001010e when using getSaveFileName

joeQ

@11hours ok, let's test again.

test the below code.

QString fileName = QFileDialog::getSaveFileName(this, tr("Save File"),"",tr("Images (*.png *.xpm *.jpg)"));
qDebug()<< fileName

@joeQ it is still the same

@joeQ I think it is because the method QT uses to call WINDOWS native dialog is not safe, so WINDOWS throw the error, right?

From these test, i am sure this error is not your fault.

did you used DontUseNativeDialog option, you can test it.


QFileDialog::DontUseNativeDialog

Do not use the native file dialog. By default, the native file dialog is used unless you use a subclass of QFileDialog that contains the Q_OBJECT macro, or the platform does not have a native dialog of the type that you require.

test code snippet

QString fileName = QFileDialog::getSaveFileName(this, tr("Save File"),"",tr("Images (*.png *.xpm *.jpg)"),0,QFileDialog::DontUseNativeDialog);
qDebug()<< fileName
``

@joeQ yes, like I said before, if i use DontUseNativeDialog, there will be no error reported.

From this, I think i got into problem same with you before. ok, you can use one macro in your program, use the windows native file dialog under release version, not use native file dialog under debug version.

void MainWindow::StOpenFile()
{
    /** ... */
#ifdef DONT_USE_NATIVE_DIALOG
    QStringList ltFilePath = QFileDialog::getOpenFileNames(this,
                                                           tr("Open files"),
                                                           defaultDir,
                                                           QString(STR_OPEN_FILE),
                                                           0,
                                                           QFileDialog::DontUseNativeDialog);
#else
    QStringList ltFilePath = QFileDialog::getOpenFileNames(this,
                                                           tr("Open files"),
                                                           defaultDir,
                                                           QString(STR_OPEN_FILE));
#endif

/** ... */
}

thank you @joeQ.
I'm sure now, the error also happens under release version, cause I tried using VS to compile, and it reported the same error under release version.
I don't know why QT does not report it.
I decide ignore the error temporarily.
thank you guys!

although this problem is not solved yet, it seems like another issue in COM technology. I guess, in WINDOWS system, qFileDialog calls FileDialog in WINDOWS API.

joeQ

@11hours did you move your programer to another computer to test it ? win7? or win10? or 64bit Qt etc.

@joeQ sorry, my friend. I was out of the earth without internet yesterday. I have't tried yet. Let me find some other computers.
