GridItemRenderer does not update on the updating of the data
I have a DataGrid with 4 columns, 3 using GridItemRenderer. The data to the DataGrid control are divided into a number of pages depending on the size of the grid and the amount of data.
The last 2 GridItemRenderers use a custom component that draws a percentage with the amount of the percentage bar.
When the DataGrid control is imagined, work of GridItemRenderer of the 1st great column. It changes color based on a value.
The 2 last GridItemRenderers do not display anything. When you click on the second page, it displays, however the first line does not show the value of the text. When you click on another page, then the previous pages drawing values cover the current values. that is, he draws the percentage bar based on the values of the previous line.
Initial page
The 3rd column is empty. I tried to put the percentage bar drawing information directly in the GridItemRenderer, but it appears that for the first row.
Second Page
When loading the second page, it shows the bars, however, the values are disabled. The red in the 100% bar is for another bar.
First Page Reloaded after click navigation
Navigate to the first page only gives wrong results as well. The first line is missing in the percentage value.
The GridItemRenderer is quite simple. I overrid data function to add information. I even tried a few Invalidate methods to see if that might solve the problem. There can be no.
<? XML version = "1.0" encoding = "utf-8"? >
" < = xmlns:fx s:GridItemRenderer ' http://ns.Adobe.com/MXML/2009 "

monthBar.setBar (Math.floor(this.height *.99), Math.floor(this.width *.99), thisPercentage);
}
super.invalidateDisplayList ();
super.invalidateProperties ();
}

I decided to just use FlexGlobals to solve the problem.
Overall, I put the width and height values. By default the height and the width is after that the screen's size.
dataGridColumnWidth = Math.floor (siteDataGrid.width *. 25);
Then, in the DataItemRenderer, I used the FlexGlobals for the height and width. I left the if statement else in there, just in case there is a solution. But I probably should get out.
Import mx.core.FlexGlobals;
override public function set data(value:Object):void {}
Super.Data = value;
if(value == null) {}
return;
} else {}
var thisPercentage:Number = new Number (data ["SevenDayPercentage"]);
If (this.height! = 0 & this.width! = 0) {}
sevenDayBar.setBar (Math.floor(this.height *.99), Math.floor(this.width *.99), thisPercentage);
} else {}
sevenDayBar.setBar (Math.floor (FlexGlobals.topLevelApplication.dataGridRowHeight *. 99), Math.floor(FlexGlobals.topLevelApplication.dataGridColumnWidth *.99), thisPercentage);
}
}
super.invalidateDisplayList ();
super.invalidateProperties ();
}

XML with a member does not properly in the data model
I use XmlDataAccess class to load an XML list in GroupDataModel. Everything works fine if the XML file has more than one Member, however, it does not load if the list contains a single member. I use the following code to get the XML content:
QVariant list = xda.load(home.absoluteFilePath("MembersList.xml"),"/members/member");
I need to know if the list has only one or 2 + members, so I can direct the data model to load with the appropriate settings. Can I know the number of members in the list?
This problem is closely related to this question, where a solution QML is given.
Hi Mitch99,
Please see this forum post for a workaround for this problem. I tested it and confirm that it works as with QML.

AS the operator does not work with the DATE
Hello
I have a simple select statement and in the WHERE clause if I use AS with a date field it doesn't but it works with a string field. For example:--does not work. does not bring any rows Select * From MyTab Where time_period Like '%';
Where time_period is of data type DATE and VARCHAR2 level_code.--works and brings ALL data Select * From MyTab Where level_code Like '%';
Hello
That's how AS is supposed to work.
x LIKE y
won't be TRUE if x is ZERO, no matter what.
If you want an expression which returns TRUE when x is NULL and y '%', then use NVL to map NULL to an appropriate value.
For example:Select * From Mytab Where NVL ( TO_CHAR ( time_period , 'MM/DD/YYYY HH:MI:SS AM' ) , ' ' -- One space ) Like '%';
TO_CHAR to explicitly create a string based on a DATE, in the format that you want. Do not rely on implicit conversions.

socket InputStream does not get all the data, please help
I've been doing stuff of network on blackberry for quite awhile, but still using the http connection.
I have to use the socket for a piece of my application connection, but could not do the work.
This code is what I do
String url =
"socket: / / ' + rmserver + ': ' + rmport;
Socket SocketConnection = Connector.open (url) (SocketConnection);
socket.setSocketOption (SocketConnection.KEEPALIVE, 1);
OutputStream = socket.openOutputStream ();
InputStream = socket.openInputStream ();
send something here using outputstream
int
If (f > 0) {}
do somwthing
}
AV is always 0.
I don't know that my server sends data successfully. I run the network packet capture tool etheal on the MDS Server, I can see given reached MDS Server, but they never come to my device app.
The outputstream works very well, I can send data from my application and my server code gets all of them.
Where should I check? If it is http, I can turn on the debugging http on MDS log and see all network traffic, but for the socket connection, data packet is not connected (or I missed where it is).
Is someone can you please tell me where I should go to understand why?
Please try the suggestion to remove the check mark on InputStream.available.

labVIEW does not correctly read the data
I'm new to LabVIEW (use it for a subject in College), but I coded a short program which counts the fronts and edges of a signal (to be used with the addition of a quadrature encoder).
I tested it at low frequency using the block to simulate Signal and it works fine, but as soon as I have the pump up to anything above 4 Hz, it starts to play up (including a positive benefit as a negative benefit). 10 Hz, it is not the edges at all. Same thing with the encoder - when turning very slowly the counties to register very well, but even a moderate speed and it will start missing.
Don't know what the issue is. The code is pretty simple, so I don't know how this would have caused the problem. Here's a copy of my counter block (the entrance of true/false indicates whether to count the upwards or downwards).
Are adjust you the length of your signals simulated when you vary the frequency?
Your Subvi seems to be just looking for a transition in a waveform.
Your simulated signal Express VI is set up for the sampling frequency of 1000 Hz and 100 samples. If the outer loop iterates at 10 Hz. If your frequency of 5 Hz, then you will have 1 transition in the waveform section and you will be able to detect it. You go higher in frequency, then you could have multiple transitions in your waveform, but the Subvi seeks only to the first, and he might not even have this one. Remember when I said that you need to run your loop two times faster than the incoming wave? Well now you see that the ratio of 2:1.
Adjust you the length of your simulated signals that you set the frequency so that you don't get multiple transitions on the waveform that you generate each iteration of the loop.

My apple pencil does not work after the 9.3.4 update.
My apple pencil does not work after the 9.3.4 update. I tried to restart but still does not work. Tried to forget the device and whenever I connect the pencil to the ipad pro, it is said that it does not recognize the cable / device. Help please.
< re-titled by host >
Greetings RechargeableJam,
Welcome to the communities of Apple Support!
I see that your Apple pencil does not work after update to iOS 9.3.4. I guess it's about to have a problem with something that worked with the previous version of the iOS software. I'm happy to help you to help you find the best resolution.
First of all, let's close open applications on your iPad Pro. This can ensure that there is nothing running in the background that is causing a conflict. The following article will help you:
Force a nearby application on your iPhone, iPad or iPod touch
Then connect the pencil of Apple and see if it is recognized for the time being. If you don't see the Pair button, wait a minute while your Apple pencil costs. Then disconnect your Apple pencil, Plug and back on hold until you see the button in hand.
Best regards.

Does not connect with the e-mail server after update.
Thunderbird ran an auto update yesterday. Then it just stopped working. It does not connect with the Comcast email server. An error message appears "Unable to connect" and "the connection was refused when attempting to contact live.mozilla.messaging.com. I don't want to uninstall and reinstall for fear of losing my emails and address book. How can we get Thunderbird set, there is no tool in the toolbar to enable the debugging and correction of program errors.
I use Thunderbird version 38.1.0.
Thank you.
The problem solved itself, Thunderbird has just started working. I followed the thread suggested by Christ1 and found none of it applied. No malware, no browser, no certificate error security block. I did, however, in Thunderbird, under Tools/Options/General uncheck the button for "When Thunderbird launches, show the Start Page in the message box." I do know that if this helped, Thunderbird still do not access Comcast mail for hours after that, even with several stops and restarts.
Until the next problem...

If you have any ideas, I had appreaciate that your expertise!
Hello arcandl, at the launch of the firefox is not after you double-click the shortcut, it is sometimes also a sign of active malware on a system.
you might want to try running a scan with some various other security like the free version of malwarebytes and adwcleaner tools that are specialized to remove the adware and browser hijackers. -
