[SOLVED] QNetworkAccessManager get

toho71

I just want to send a value and change it on the website.
Is this possible

@ QNetworkAccessManager manager;
QNetworkRequest request;
request.setUrl(QUrl(QString("http://...--/forms.htm") + QString("?") + QString("m_dNominalVA=90000")));
reply= manager.get(request);
@

I don't get an error. but it doesn't change the value on the page.

I thought that QNetworkAccessManager::get was used to read something from a url, not the opposite...

Seems right, could it be the constructed URL has a wrong parameter? What if you use it in a web browser? Does your web page support the GET method?

Yes it does.
And the value changes.
I'm trying to debug on the web side and see what the value is .

Here is the solution of this problem.
First
@void Start::sendStartValues()
{
QNetworkAccessManager manager = new QNetworkAccessManager(this);
setUrl("http://--...*/forms.htm" + QString("?") + QString("m_dNominalVA=95000"),manager);
}@

And I tried to do like this and it worked.
@
void Start::setUrl( const QString& url, QNetworkAccessManager *manager )
{
reply = manager -> get( QNetworkRequest( QUrl( url ) ) );
connect( reply, SIGNAL( finished() ), this, SLOT( replyFinished()) );
}@

maybe there is an other solution to this but I dont know how.

I don't see the difference, apart the wrapping method code. The only thing new is the connection of the finished signal. Is that the solution?

toho71

Nope I had that before and yes I don't see the diffrent solution that made this work either but know it works.
Maybe this is the diffrence
@QNetworkAccessManager *manager = new QNetworkAccessManager(this);@

As you gave no complete code in your first post, this is much likely to be the problem. If you put that into a method, manager->get() returns immediately, the method ends, the stack variable is deleted. That's how C++ works, no Qt magic.

Yes
To much java and vb and no c++ expert.
well I try to learn and this forum is very helpful.

Thanks
