Group data model does not

Hello

I am developing a revision update for my app BB10 stunts and I use a data model to pull in the elements of the application do not forget; the only problem I encounter is that I can't get the data model of the group work so that I can arrange the items by the first character instead the data are currently presented as Z - A, even if I could get it to display in A - Z would be enough, but what I am looking to achieve is to get the model to display in A - Z and then sort by the first character, while a header for each letter is displayed.

Here is the list (QML) and my data model (C++)

ListView {
                            dataModel: _noteBook.model

                            listItemComponents: ListItemComponent {
                                type: "item"

                                StandardListItem {
                                    title: ListItemData.title
                                    description: ListItemData.status
                                }
                            }

                            onTriggered: {

                                _noteBook.setCurrentNote(indexPath)

If something you can help me with then this would be very useful - if you need to see more of code then let me know too!

Thanks in advance

Try to add in constructor (after a call to setGrouping):

QStringList keys;
key<>
m_model-> setSortingKeys (keys);

May require alterations, I have not tried this compilation.

How can I Data Modeler does not generate constraints on NNC_ tables?

Hi all
Unfortunately I have not found the answer using Google ;-)
When I generate my DDL scripts on my model on some tables Data Modeler (version 4.0.0) automatically generates constraints on the columns of the table "NNC_" for example:
CREATE TABLE STG_DURCHGANGSKNOTEN
(
ID NUMBER CONSTRAINT NNC_STG_DURCHGANGSKNOTENv1_ID NOT NULL,
Kilometrierung VARCHAR2 (20) CONSTRAINT NNC_STG_DURCHGANGSKNOTENv1_Kilometrierung NOT NULL,
Letzte_Aenderung DATE CONSTRAINT NNC_STG_DURCHGANGSKNOTENv1_Letzte_Aenderung NOT NULL,
Knotentyp VARCHAR2 (100) CONSTRAINT NNC_STG_DURCHGANGSKNOTENv1_Knotentyp NOT NULL,
Name VARCHAR2 (100),
BZ_Bezeichner VARCHAR2 (100),
GUI_Bezeichner VARCHAR2 (100),
Spurplanabschnitt_ID NUMBER NNC_STG_DURCHGANGSKNOTENv1_Spurplanabschnitt_ID CONSTRAINT NOT NULL,.
XML_Document XMLTYPE
);
How can I avoid this? I like to just get something like this:
CREATE TABLE STG_DURCHGANGSKNOTEN
(
IDENTIFICATION NUMBER NOT NULL,
Kilometrierung VARCHAR2 (20) NOT NULL,
Letzte_Aenderung DATE NOT NULL,
Knotentyp VARCHAR2 (100) NOT NULL,
Name VARCHAR2 (100),
BZ_Bezeichner VARCHAR2 (100),
GUI_Bezeichner VARCHAR2 (100),
Spurplanabschnitt_ID NUMBER NOT NULL,
XML_Document XMLTYPE
);
Thank you

Hi Matthias,

The NOT NULL Constraint clause appears likely because 'Not Null Constraint Name' property is set to the column. (It is indicated on the Panel "forced by default and ' in the column properties dialog box.)

To stop these products, you can go to the Data Modeler/DOF of the preferences page (on the Tools menu) and set the option 'generate short form of NO forced NULL.

Note that there now is a forum specifically for the Data Modeler: SQL Developer Data Modeler

Data Modeler does not connect to SQL Server database

I click connect on New / select connection to the base and nothing happens. No connection is added to the list of connection in the Import Wizard dialog box (file-> import-> Oracle Designer model) so I can't go forward with the wizard and I can't connect to my SQL Server DB.
The connection works very well according to the test and to connect buttons on the New / select connection to the base dialogue. Initially, there was errors, reported originally by Test and Connect, but those that have been resolved with minor changes to the URL JDBC and CLASSPATH for jtds.
Is there a Data Modeler error log which could give an overview of what's going on? Everyone knows this?

the windows boot configuration data file does not contain a valid entry os

Hello

I got this message when recovery... I can't get the windows... I have the CD recovery, but when I boot it... It gives me this message

the windows boot configuration data file does not contain a valid entry os

How do I solve this problem

Hello

Assuming that it's just a problem with the recovery media, here's another solution, you can try.

Before you try the following, make sure that you can always read the character product activation key 25 on your label Windows COA (5 blocks of 5 alphanumeric games).

An example of a COA label can be seen here.

You can create a Windows 7 installation disc yourself using another PC - just download the good Disk Image ( it must be the same version that originally shipped with your laptop - IE if your laptop comes with Windows 7 Home Premium, that is the file you need to download ) from the link below and use an app like ImgBurn to burn the ISO correctly file on a blank DVD - a guide on the use of ImgBurn to write an ISO on a disc is here. The source of the Image is - Digital River.

Images of Windows 7.

Use the disk to perform the installation, enter the activation key of Windows on the label of the COA at the request and once the installation is complete, use ' 'phone Method' described in detail in the link below to activate the operating system -this made method supported by Microsoft and is popular with people who want to just have a new installation of Windows 7 without additional software load normally comes with OEM installations.

All pilots additional and the software you may need are located by entering your full model number or Nr here.

Yosemite user model does not

I have 20 macs in a University laboratory image in the same way, with a user model that I created. Worked fine for several months. Lately, the chances that my user model does not load correctly is 50-50. This takes the form of:
- the loading dock is generic and does not include my shortlisted apps
- wallpaper is the default 'Yosemite' image and not the wallpaper that I created
- or, the mounted drives are not displayed on the desktop.
Pictured above, the bottom image is what I call a wrong profile. It is in this profile, you can see that the dock, HDD and wallpaper are not loaded; However, things like the Finder and Safari open to the correct location, based on a template.

I can log in and out of the same machine all day and arrive at a 30 to 50% chance of the model charge properly. However, I need this number to 99.9%

Our laboratory is partially controlled by JAMF/Casper to load scripts at startup. These logon scripts in the form of:
- load the customer print PHAROS
- load a "alert of emergency of the University" application in the dock
- If the user has a folder on our server, xsan, Casper Mont scripts this folder on the desktop (this feature works on our Mavericks stations, but is broken in Yosemite).
What process occurs when a user connects and the model is pulled? Is it possible that Casper connect you scripts could be in conflict with the creation of models of the user?

Solution: The question is a folder called Non_localized, reflect the English.lproj content with this file in template/User.

Why do write can not be performed because the number of data channels does not match number of channels in the task.

Possible reasons:

Scripture cannot be performed because the number of data channels does not match number of channels in the task.

When writing, provide data for all channels in the task. You can also change the task so that it contains the same number of channels as the written data.

Number of job channels: 8
Number of data channels: 1

Lama says:

The DAQmx vi writing gives me the error. If I run a single channel, isn't a problem. Multichannel gives me error.

You are funny! Why tie yourself to work VI (single channel) instead of one that gives you errors (multichannel)?

(If your car does not work, you bring car your wives to the mechanic, right!)

What is the exact text in the multichannel 'physical channels' when you do the AO control?

Lama says:

I did a sequence to ensure that each function has been run in the correct order. Wouldn't a race condition.

All you have to do is wire the 'start of task' error at the entrance of error of the DAQ assistant and then back to 'stop task' and things will run in order. Guaranteed! Think the stream! Everything else can run in parallel or the order is irrelevant.

First convert the sequence stacked to a sequence of plate, remove the flat sequence and add the mentioned son. Now, do a "cleaning pattern.

A when stacked with the inhabitants of the sequence is one of the worst construction you can possibly do. It makes the code difficult to follow, impossible to maintain, difficult to debug.

How can I correct a problem accessing my firewall settings because the Group Policy client does not connect to windows?

I have tried everything recently adjust the settings of the firewall from my window and a box appears saying that after an unidentified error, I can't access my firewall. After some research, I discovered that it was because my client group policy server does not connect and a small box appears saying that whenever I connect to my laptop. It is not effect my use of the internet at all, so I've never bothered to see what that meant until now I need to access my firewall. I tried to adjust the settings in group policy, but everything is gray and I can't change anything. I use an admin account so I don't know why I can't set the parameters. I'm completely stuck and I don't know that much about computers. Is there anything else I can try? I also tried a system restore, but it lasts for a long time and I can return only 5 days. Thank you

Hi Sheldon,

Are you connected or connected to a work network or domain? If so, this could be a policy governed by your network administrator, and you will not be able to change it.

Smartphones blackBerry 9900 data Plan does not work!

Hi, new here, great site!

I'm from Canada, with Koodo and bought a unlocked 9900 opportunity, my neighbor via a Classifieds site, and as much as I know it was his business phone.
I wiped it it clean and improved the operating system to 7.01

I noticed that the previous service logo remains still (Rogers) during boot-up/shutdown, hmm, OK whatever he is working with Koodo.

I called Koodo to allow data, but nothing works. I called them and they told me to enter "bb.koodo.com" in the APN field with no username and password. Then to save the host Routing Table (he told me that he registered very well) but I did not receive a message. Also, we have removed battery and tried everything again. It still does not.

It is H + at the top right of the screen, but who has always been there.

She said that maybe the phone was restriction IP since I bought it used, and maybe BB Swiss Army tool could help me get off, but she didn't know how. So I downloaded and pushed some buttons (more precisely remove COD) and really messed up my phone... lol

Just reinstalled OS7.01 once again and fortunately had a fairly recent backup.

Suggestions for making data work, or do I need a new phone?

Hello and welcome to the community!

Let's start there, because who can be tricky depending on what exactly is meant by "business phone". Reference:
- Article ID: KB05099 Steps to take before selling or after the purchase of a used BlackBerry smartphone
Many of the steps can only be carried out by the seller... for example, if the prior carrier still has a BIS account allocated to that specific device, so no other carrier will be able to create a BIS account for her, and a BIS account is required to use wisely. As a general rule, a carrier will come out only the BB from the account when the real account holder made the request... and you will not if this situation applies.

In addition, if the device has been activated BES, you need to follow additional steps. Reference:
- Article ID: KB30076 How to check for an it on a BlackBerry smartphone policy
If there is an IT strategy, then there are a special method, you need to remove it, but it will be successful if the BES server, to which the device has been set already has the removed feature of it... you may need to ask the previous owner about it. If this BES server was deleted, you can use this method to clean up the it policy:
- Article ID: KB31291 How to reset a BlackBerry smartphone to factory using BlackBerry Desktop Software Settings
It is necessary to use this exact method... refer:
- Article ID: KB16307 Actions performed by the BlackBerry smartphone during the removal of the user stored and application data
Now, with all these preliminaries of the road...

Serious9900 wrote:

As you guessed, it's irrelevant. BBs are still originally designed for a specific carrier... and some of these contractual carriers with BB to place a splash screen of starting the device ROM, that can never be changed. But, it does nothing other that that unit was built for this carrier... but as long as all other things correctly, it is not serious at all.

But, to be clear, when you say "it works on Koodo", I guess that's your voice services? And are all now, you must operate your data services? If telephone services do not work correctly on Koodo, then it is useless trying to get data services going.

But now say you "nothing works"... should I continue to assume this are information specific to the data, and that telephone services continue to operate properly on Koodo? Sorry for being blunt, but clarity is critical or waste us time on unnecessary things.

When you say "he told me that he registered very well", which means exactly please? This means that he said something like 'Check pending', 'Record sent' or some other message popup? Once again, here the clarity is critical. If that's what you saw, then indeed it is not registered correctly. Rather, he made the application very well... but until the enrollment message arrives in the Messages application, then the intervention is required since the data network of the carrier did not and until it nothing for the data will be working.

Serious9900 wrote:

Upper case H +? Once again, just double check, since if she was tiny, that it would mean something completely different from that of capital letters. Top of case, this is what it must be.

I don't know what she thought about it. May be restriction of BES and if the above process I gave you can purify that.

Never good to a few buttons when you don't know what you do... I don't remember if BBSAK is able to remove political or not, but it can do a very good cleaning.

Serious9900 wrote:

And that could be part of your problems. If, for example, the device has one IT political edge, while part of a full process... which means that even if you happen to clean off, a complete restoration simply will return to the instrument, turning to your right back to where you started backup/restore. Instead, to do only a partial backup or restore, and more precisely to avoid data bases that have to do with THIS, political, business or something similar... the conservative approach is to only to backup/restore of critical databases you need (for example, contacts, calendar) and manually reconfigure the rest. Remove a policy is a tricky thing.

I think you have enough to start on top. Another question about whether Koodo, however, is if their network is configured to auto-fill your specific with entries HRT device model and service book. If their network is not, while actually explains everything. No carriers configure their network to support all models of BB... each one chooses a subset of the model numbers of BB and configure their network accordingly. But trying to use a model number BB on a carrier network that is NOT configured for this model results in number exactly what you live... their network will not automatically grow some HRT and SB entries on your device because their network does not recognize your device as a model BB number taken in charge.

Looking at a reference that I can find, it seems that Koodo is configured for the 9360, 9300, 8530 and 9790. But not for the 9900. Now, is that with a proverbial grain of salt... that reference does not necessarily mean that the network of Koodo is not configured for the 9900, it's just an indicator that is not.

Good luck and let us know!

-You also get an invalid identifier error when executing this query sql for a data model, but not in TOAD/SQL Developer?

Hello OTN.
I don't understand why my sql query will pass by in the data model of the BI Publisher. I created a new data model, chose the data source and type of Standard SQL = SQL. I tried several databases and all the same error in BI Publisher, but the application works well in TOAD / SQL Developer. So, I think it might be something with my case so I'm tender hand to you to try and let me know if you get the same result as me.
The query is:
SELECT to_char (to_date ('15-' |)) TO_CHAR(:P_MONTH) | » -'|| (To_char(:P_YEAR), "YYYY-DD-MONTH") - 90, "YYYYMM") as yrmth FROM DUAL

Values of the variable:
: P_MONTH = APRIL
: P_YEAR = 2015
I tried multiple variations and not had much luck. Here are the other options I've tried:
WITH DATES AS
(
Select TO_NUMBER (decode (: P_MONTH, 'JANUARY', '01',))
'FEBRUARY', '02',.
'MARCH', '03'.
'APRIL', '04'
'MAY', '05'.
'JUNE', '06'.
'JULY', '07',.
'AUGUST', '08'.
'SEPTEMBER', '09'.
'OCTOBER', '10',.
'NOVEMBER', '11'.
"DECEMBER", "12."
'01')) as mth_nbr
of the double
)
SELECT to_char (to_date ('15-' |)) MTH_NBR | » -'|| (TO_CHAR(:P_YEAR), 'DD-MM-YYYY') - 90, "YYYYMM")
OF DATES
SELECT to_char (to_date ('15-' |: P_MONTH |)) » -'|| ((: P_YEAR, 'MONTH-DD-YYYY')-90, "YYYYMM") as yrmth FROM DUAL
I'm running out of ideas and I don't know why it does not work. If anyone has any suggestions or ideas, please let me know. I always mark answers correct and useful in my thread and I appreciate all your help.
Best regards

So I thought to it. It seems that there is a bug/lag between the guest screen that appears when you enter SQL in the data model and parameter values, to at model/value data.

Here's how I solved my problem.

I have created a new data model and first created all my settings required in the data model (including the default values without quotes, i.e. APRIL instead "Of APRIL") and then saved.

Then I stuck my sql query in the data model and when I clicked ok, I entered my string values in the message box with single quotes (i.e. "in APRIL' instead of APRIL)

After entering the values of string with single quotes in the dialog box, I was able to retrieve the columns in the data model and save.

In the data tab, is no longer, I had to enter the values in single quotes, but entered values normally instead, and the code worked.

It seems the box prompted to bind the values of the variables when the SQL text in a data model expects strings to be wrapped in single quotes, but no where else. It's a big headache for me, but I'm glad that I solved it, and I hope this can be of help to other institutions.

See you soon.

Report of the Group of left does not sort descending

Hello seniors...

I have the following query which produces the result as you wish below at the SQL level; I aim to lines to be copied in descending order...

SQL> SELECT Z.ACATG_TYPE, Y.EXPN_CATG, z.ACATG_DESC, y.expn_code, y.expn_name,

9 rows selected.

But when I've made use of the query above in my report with an Option of left group, I understand not sorted in descending order.
With a tabular report, it sorts correctly as indicated above.

Schot screen for a better idea of my report is attached for reference.

I want the lines with acatg_type = 'I' to be displayed first.

Sorry for fixing is not SQL full, but no problems, or even not at all necessary, I can do the same.
Given that this is a long online created SQL view. thought that the solution might come out showing as much a part only.

I use report 6i to 10g.

Please help me.

Hello

Verify that the order of the fields in the "data model", in the respective application group ACATG_TYPE column should be first by EXPN_CATG, then expn_code.
Also check the order of the breaking of all columns.

I hope this helps.

Best regards

Load model does not work
I have a problem. I defined a definition of data with the code "my_data_definition". I model a link with my definition of data and define a competitor with the name short "my_data_definition".
Out of the report is PDF but does not work, I get "File does not begin with '% PDF -'". When I run applications I do not have any available.
What I am doing wrong?
Hello

The defined simultaneous program must have an output XML defined in its definition.
