Open an HTML file in Internet Explorer

[MSDQuick]

Hi guys;
When the user presses a button, I would like to open an HTML file in Internet Explorer.
I tried to use these codes, but it doesn't work:

void MainWindow::on_pushButton_clicked()
{
    QDesktopServices::openUrl(QUrl(":/Images/Help.html", QUrl::TolerantMode));
}

Thanks for helping.
MSD.

@MSDQuick said in Open an HTML file in Internet Explorer:

but it doesn't work

And what does happen then?

Anyway, is something like https://stackoverflow.com/questions/37898660/qdesktopservicesopenurl-does-not-work-neither-for-urls-nor-for-local-files-o relevant to your situation? There are several other Google hits for QDesktopServices::openUrl, are they relevant?

It does any thing.
I changed the code to this:

QDesktopServices::openUrl(QUrl::fromUserInput("Help.html","/Images/"));

Now it opens a web browser and puts "Help.html" in address bar and shows error opening page.

My HTML is located in my application resources directory, and I think it can not find that address.

Then I presume you need to specify a (more) absolute URL. Have you tried /Help.html or something like http://localhost/Help.html? Have you tried opening the file in IE and copying the page's URL back into your source code? I don't even know whether you are servicing these web pages via an HTTP server or just via direct file access...?

What I need is :
I created a Help file (as a HTML file) about my application, and I put it in my "resources" directory. Now I want to open that file when I press a button in my application. That's all.

Thanks.

You may have better luck if you deploy the file to your application path (or a subdirectory thereof) and then open the URL:

QDesktopServices::openUrl(QUrl("file:///" + QCoreApplication::applicationDirPath() + "/help.html"));
