QUrl.encodedQuery () does not properly encode '+' symbol

I submit an HTTP POST, like this:

QNetworkRequest request(url);

QUrl params;
params.addQueryItem("myParam", myParamStr);

QByteArray byteArrayObject = params.encodedQuery();
QByteArray postDataSize = QByteArray::number(byteArrayObject.size());

request.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");
request.setHeader( QNetworkRequest::ContentLengthHeader, QString(postDataSize).toUtf8() );

However, when the myParamStr string contains a symbol '+', that it does not get encoded as '% 2B' according to the w3 reference http://www.w3schools.com/tags/ref_urlencode.asp. Is originally from the side (PHP) server not not to treat the '+' correctly and it essentially gets deleted and replaced by ' '.

Does anyone have an idea how to solve this problem? To work around the problem, I do a replace string Manual of '+' with '% 2B' but I don't know if it's something that could create problems on the road not a clean solution would be appreciated.

Hello! I think you should encode the individual parameters as well. One of my apps (should work in Qt 4.8 and waterfalls, Qt 5 these classes has changed):

QUrl params;

params.addEncodedQueryItem("email", QUrl::toPercentEncoding(email));
params.addEncodedQueryItem("last_name", QUrl::toPercentEncoding(lastName));

QByteArray data = params.encodedQuery();

QNetworkReply *reply = networkAccessManager_.post(request, data);

Safari Web Clip does not properly

Hello everyone

I have a problem with safari Web Clip and that is does not properly for almost all pages, as example, I participate in a contest of therapy dbrand/unbox, and I really don't want to open the web page, whenever a new winner is announced, so I created a web clip, but it does not work well When I click the web clip icon he asked the location of the clip and when click on done, the web clip is from a different region and I can't fix.

Is this some sort of bug or can I fix it myself?

Web Clip still didn't work if the cut element remains in the exact same on exactly the same site. This is apparently not the case here.

Dashboard widgets in general, are an old technology that has not been updated in many years.

Toshiba 47L7453DG - CEC does not properly using exernal amplifier

I bought Toshiba 47L 7453 a few days ago.

It is connected to the amplifier Onkyo TX-NR535 but CEC does not properly. Volume control works fine but On / Off or stanby does not at all.

My previous TV Toshiba 42XV635DG was communicated by the CEC with the Onkyo even without any problem.

The wire connection is HDMI 1.4 certified.
Maybe the problem is with the firmware of the TV.

Maybe someone had the same problem.

Any suggestion?

Thank you

Hello

From my point of few TV and amplifier are connected some CEC (Volume control) functions that work. I think you should check the auto power settings and HDMI CEC standby control system.

Manual, you will find some important notes:

Problem does not occur in safe mode. Failure seems to occur on any key or the video style.

Any material support is the manufacturer of the hardware regardless of the operating system that you choose to use. As it is unlikely that you have a Microsoft video/graphics card - one you have and have you downloaded and installed the latest drivers/software they provide for your particular device?

Hi Olliewoods,

(1) since when are you facing this problem?

(2) what is you receive the exact error message?

An application installed on the computer may be the cause of this problem; I suggest you try the following steps:

Method 1: Put the computer to boot to determine which application is causing the problem.

Follow step 1 in the link below,

How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

http://support.Microsoft.com/kb/929135

If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem.

Continue with the remaining steps to pin-point on the third party service.

After find you the program that is causing the problem, you will have to perhaps to update or install a newer version of the program, if you rarely use that you should consider uninstalling the software.

Important: n ' forget not the computer to start normal follow step 7 in the link.

Scrolling the page does not properly respond to BlackBerry Curve9360

Hello friend

I have developed applications for BlackBerry (JqueryMobile, Phonegap) the application works fine in BlackBerry Torch 9800.

But once I've installed in BlackBerry Curve9360, scrolling of the page does not properly, that I am not able to view the complete list of items and long text.

Help, please

I came up with the solution, the problem occurs because BlackBerry Curve 9360 isn't a touchscreen, there fore scroll doesn't work.

In my applications, I add 2 pages "index.html."

on the first page, you have to test if the device is not touch and redirect to the second page.

Do not use the page for "BB Curve" scroll and any other animation like CSS "" - webkit - transform: translate3d "»

The other js script go without a problem.

The page "BB Curve" to redesign the html for use with the cursor,
For example, the menu is smaller, the police is smaller.
the size of the screen is fixed.
Dimension height is better indicate a value min eg 300px
etc...

touch screen keyboard symbols does not properly

I bought recently an Asus transformer convertible portable book, which features a touchscreen removable "tablet" next to the keyboard. Most of the time I just use the screen without the keyboard as I have the touchscreen keyboard. I have windows 8 is installed.

The problem is that no matter when try to use the keyboard section and press a key, it acts as a regular keyboard that requires shift for me to press a button to get some symbols. Such as SHIFT, press 1 to get! and 2 to get @ etc.

This is a problem because there no way for me to 'shift' then that in this section, which means I have no way to use the majority of the symbols, unless I was to give the keyboard, which I won't do. It's the same with the? on the main screen to give me a / instead.

Someone else has this problem as well? Becomes more and more frustrating.

I searched for answers, the closest, I had was that it could be the UK keyboard, which is not, as I discovered, I have the English (Canada), I selected when setting up my computer.

The keyboard I used was the touch keyboard, similar to that on the picture of this Article:

http://Windows.Microsoft.com/en-us/Windows-8/using-touch-keyboard

I tried also a lot of different things that I could think of to try to make it work, such as the SHIFT key, and then selecting the specific symbol, neither of which worked, moving to the symbols section and pressing one and also hold out the number or symbol that coincides with it.

Honestly I don't know what happened, but it seemed to have fixed itself after my computer up to date a little after I posted this. which is always strange, because it was updated several times before and the problem remains.

IM praying that the problem does not return, but I'm not keeping my hopes.
