Pass-through of a jump Page or back to NavigationPane sheet

Hello

Is it possible to get back data from one Page to a NavigationPane pushed him?

1. I have a NavigationPane who opens a Page

2. on this Page, the user of data entry, then close Page.

3. I would like to pass some data from this burst page and going back to my Main Page of NavigationPane.

4. is it possible to do?

Any ideas on how to do this? Thank you!!!

There are several ways to do this:

(1) declare a signal on the page. It emits when data changes:

signal signalName(string param1, string param2)   // params are optional

...

signalName('someData', 'otherData')

On NavigationPane after creating the page to connect to this signal:

page.signalName.connect(funcname)

Before destroying the page to disconnect signal (this is not done automatically):

page.signalName.disconnect()page.destroy()

Create a JavaScript function to process the signal:

function funcname(param1, param2)
{
  myProperty = param1
}

This method is useful when the data is updated regularly.

(2) If you need to access the data only when the page is popped, then simply access the page properties in NavigationPane onPopTransitionEnded handler.

Something like:

In NavigationPane:

onPopTransitionEnded: {
  myProperty = page.otherProperty  page.destroy()
}

...
in Page.qml:

Page {
  property alias otherProperty: someControl.someField

upd: If you need to transmit these data to another Page, so something like this should work:

onPopTransitionEnded: {
  // 'top' property references a top page in NavigationPane
  top.myProperty = page.otherProperty
  page.destroy()
}

I don't know if 'top' made reference to a new home page or the page that is be popped. In later case at() method can be used instead.

(3) create a C++ class to store data and export of its instance to QML. Set the properties inside (Q_PROPERTY). Edit them directly from QML and allows the monitoring of the changes of their element of connection of QtQuick (connect () /disconnect () method will work as well).

It is convenient to store application settings and respond to changes inside.

Passing values to the next page

Hello
I use Apex 4.2.5 in Oracle 11 g
I've created a form that transmits its value to another page when a button is clicked.
The field of employment in the page of the form has values like 'SELLER' in a folder,
"ANALYST" in the next record...
This page contains a button, and when it is selected, the values are passed to the page successfully as
The problem is that some areas of employment are having values such as "PROGRAMMER, systems ANALYST.
separated by commas in a record. When these values are passed to the next page, I get only the first job. and the rest is not.
In the previous example, I get only PROGRAMMER and not the SYSTEM ANALYST.
but when I change the field to be as "PROGRAMMER/ANALYST" then it works. Why not with commas?
Thanks in advance

Commas are used to separate the values of each element.

You should avoid passing string values that may contain any reserved characters in the URL in links. It is not to transfer data in the URL, other than the minimum possible number of discrete alphanumeric identifiers. Values required in a target page can be recovered in the element source and properties by default, calculations or using these values of process ID, or by referencing the other page element values or application already in session state.

The values containing a colon cannot be passed through the URL. The values containing commas can be passed if the value is escaped with backslashes:

&P10_ENAME.,\&P10_JOBS.\

STR-DH520 - pass through

Why my camera starts when I turn on my my TV to the receiver input. I have my ps3 connected to the receiver, then the receiver to the TV. I don't want the receiver all the time. But when I turn on the TV to the hdmi input, my receiver turns on. I have so I have to turn off the receiver and then continue 5000mAh mode.

Rrangel,

If you just reset your receiver and then you have to turn ON HDMI Pass Through. It can also be beneficial for reference manual STRDH520 to understand what settings are available and how to use them to achieve your desired results.

Passing the value from one page to the other page
Hi gurus,

I need to pass the value from one page to the other page and two pages use different AMs.
In the first page I have sellers results region table where the $vendor_name column is a hyperlink that navigates to the page Vendor_Sites. Now after accessing the second page, I want to excute the VendorSitesVO in PR of CO based on the value passed to VendorsVO (vendor_id) of first page.

can someone help me on this?

Thank you
Vincent.

You can set parameters of Pagecontext and transmit values through them. These values can be passed between pages, even if the AMs are different.

Try:
pageContext.putParameter ("Parameter1", value1);
pagecontext.setForwardURL (second page)

Apple TV 4 Audio pass through

Hi-

My current setup is: 4 AppleTV via HDMI-> Onkyo HT-R990 7.1THX via HDMI-> Samsung Smart TV 60 inch LED. The TV speakers are turned off and that all the sound elements through my 7.1 System.

My question is about how to disable the audio decoding on the Apple TV. Can the Apple TV 4 simply intercommunication audio without decoding? That's why my receiver will decode and choose the best audio configuration for content.

Having a transmission option is fairly common on most devices such as Blu - Ray players. What's not an option on the Apple TV? I know by selecting "Auto" on the Apple TV, it will send the PCM signal. Why would I have DD or PCM if the content is DTS Master for example? It makes no sense to me.

I think I have a 'Pass-through' option would satisfy loyal people optical cable and move is a real audio visual component of the Apple TV.

Does anyone know how this can be done? Your help is greatly appreciated. See you soon!

It can normally send PCM for music/video stereo and support the bitstream DD for 5.1, ATV 4 7.1 - I assumed AppleTV 4 this but have moved for a few months and don't have not connected my AV Pioneer amp just for the Samsung TV.

AppleTV does not support DTS officially, certainly not for the content of the iTunes store is not an option, but I don't know about 3rd party applications that could broadcast "other videos" of local shares.

using PostDelayedCall how to get the value passed through void * callbackData?

Can someone tell me how to get the data passed through void * callbackData?

The following code, panel_ptr has the right address but still contains zero.

void CVICALLBACK value_changed (void * callbackData)
{
int * panel_ptr;

panel_ptr = callbackData;
calculate_new_value (* panel_ptr);
}

int sign;

Panel = 2;

PostDelayedCall (value_changed & Panel, 0.2);

The problem is using the callbackData parameter if it is a pointer, it must be a pointer to something which is still topical at the moment that the callback executes. That is to say, you cannot pass the pointer to a local variable in callbackData as when the callback executes the pointer is no longer valid. You can switch from its value, instead, in this way:

... SomeFunction)

{

int sign;

...

Panel = 2;

PostDelayedCall (value_changed, (void *) Panel, 0.2);

...

}

void CVICALLBACK value_changed (void * callbackData)
{
int panel_ptr;

panel_ptr = (int) callbackData;

calculate_new_value (panel_ptr);

return;
}

There are many discussions on the forums on callbackData parameter that you might want to read.

When scrolling down using the touchpad, the cursor jumps to the back arrow

Hi, could someone tell me why when I use my touchpad, I move the cursor over the arrow down to scroll down and sometimes the cursor jumps on the back button on the screen and goes back one screen and I lose what I'm getting?

Thank you. I understand. I went to the mouse and then to the touchpad device settings and I was able to change. They were called corner buttons. They function as shortcuts to different things on each corner of the touchpad. I disabled it.

Configuration of VMware ESX 5.1/5.5 pass through for PowerEdge 2970

Hello

I tried to configure VMware ESX 5.1/5.5 pass through for a 8 GB Qlogic FC HBA on PowerEdge 2970 server.

Even after activation of the virtual technology in the BIOS, the PCI device is not listed in "Advanced settings" to configure pass-through. Attached screenshot shows the current setting of the processor.

Hello Sara

You're talking Direct path IO or single root i/o virtualization? If so, none of these features are supported on the 2970 system.

Pass through IPSEC on Cisco 857

Hello people!

I have gained reciently a Cisco 857 router. I want to do a site-to-site VPN.

I set up the ATM0.1 with "ip unnumbered" VLAN 1 interface. I have not configured the router to enable NAT or PAT. VLAN 1 is configured with a public Ip of my ISP address. Behind the cisco router, I have a Zywall 5, this device is my VPN gateway. Initially, it works very well with the other soho router but it blocks often, for this reason, I decided to change it for a cisco router.

My problem now is that the cisco router does not allow the implementation of VPN.

Need to activate the IPSEC pass-through?, how can I do this?

Thanks in advance!

WRV200 VPN pass through limits

We use a Cisco Small Business WRV200 to allow guests to our office to access the public internet, regardless of our corporate network environment. We regularly invited several visit of a company and generally these users connect to their company via a local VPN client. I noticed that after about 5 users activate successfully their VPN clients that no one else can connect to any other VPN tunnels. Internet connectivity still works when these 5 tunnels are active, but no other users can create a VPN tunnel after this point. Again, these are all movers or Pass through tunnels behind the WRV200 in one single environment NAT. is there a limit on vpn pass through or leaving behind this device connections and if so can it be changed? I expect a resolution of firmware to this problem, but it seems that it is only a single firmware version for this device. If this unit has an immutable limit, can then someone propose another product, Cisco Small Business wireless which has no limit of transmission?

Thank you...

If the NAT - T is enabled on clients and VPN gateways, there should be no problem. Otherwise, if two IPsec clients behind WRV200 are trying to connect to the same remote gateway without NAT - T active, 2 IPsec sessions could clash between them.

Where can I find click-through to a landing page?

I'm trying to find a report in Insight E10, which breaks down the click-through to a landing page. I'm looking for something similar to the report Email Click-Through line breakdown, only for a landing page. Thank you!

I just got the phone with the support of the same exact question. They do not have a standard report that gives you what you are looking for. I don't know if you have the same problem as me, but I got a job. You can create a segment that search all contacts who have visited the destination of the click on your landing page and export the list of contacts. So for us, the links that we try to follow our landing page are to .pdf documents downloads. I'm creating a segment that tells me who reviewed these .pdfs in the last x number of days (visited websites). Don't know if it works for your situation, but he did it for us. Let me know if you have any questions!
