How can I set up a database for the application on my mobile?
I develop a mobile application that allows users to check the 'weather' (I hesitate to share the exact nature of my app on a public forum, so I'll use "weather" instead) reports nationwide. A network of collaborators around the nation will download their content, and I need to be able to access this information from my application.
Who have never implemented a database before, I'm not sure what the best way to do it. I am considering a portal on the internet that my contributors can download to and then just linking to this database in my application. How can I do? Or is there a better way?
You can use a database that made your site. So let's start with that. Do you use mySQL or MS SQL? Then the next consideration is whether your entry is coming from controlled sources. For example, with your example of time can say us that areas 1, 3 & 5 report user 1 and user 2 reports on 2 & 4, which means that there is no overlap. So what will happen, you need to re-evaluate the other fields that will be registered. In general, I would like to start with:
Table user - modules, user name, password (permissions?)
Data tables - define regions, weather information, date information.
Assignment of the User_Region table - each line connects 1 user for 1 region (easier that store arrays in the table user)
Table of authorities - need users have permission, will there be an admin to substitute if something is wrong?
According to the scale of the APP, it may be necessary to make foreign key dependencies. Basically, it's just a fancy way of saying that if the region 2 is deleted for some reason any, we want to ensure that users are assigned to other territories, otherwise you get errors request looking for something that does not exist.
That's the key. He participates a lot but if you are unfamiliar with database design and implementation of index keys, foreign keys and set up the model, you can consider hiring outside help because there is a lot of work and if you are thinking of you more should build the database with growth in mind.

How can I set different background color for the slider?
Hello
I want to set a different color for track Slider, slider track is spitted into two sections by slider-button.
I want to put a left gray, the right of a white.
Under css only changes the background of the entire track, but how I can change different background color for the slider?
Any suggestion?
.slider { -fx-border-width: 0; } .slider *.track { -fx-background-color:white; -fx-background-insets: 0, 1; -fx-border-color: #faf0e6; -fx-border-width: 1; -fx-border-style:solid; -fx-progress-color:yellow; -fx-border-radius: 20; } .slider.knobStyle:focused .knob { -fx-effect: dropshadow( three-pass-box , red , 5 , 0.5 , 0 , 0 ); } .slider.knobStyle:unfocused .knob { -fx-effect: dropshadow( three-pass-box , red , 5 , 0.5 , 0 , 0 ); } .slider .thumb { -fx-background-color:rgb(224,225,226); -fx-background-repeat:stretch; -fx-background-size:stretch; -fx-background-position:center top; -fx-background-image:url("../images/volume_ball.png"); -fx-padding: 10; }
I don't know why I can't get the node of the track, track has always set to null and the thumb or the other.
After that the cursor was displayed on an active scene are you doing research?
(ex.: after you have added the slider to a scene, the scene for scene, then called stage.show ())

How can I set a default zoom for the browser (freeze)?
Hello, there is a possibility of using the CTRL ++ to enlarge the Web page, but he returned to the default zoom of Firefox in the middle which is very annoying. In general, I would like to be able to establish a certain level of default zoom and then only if necessary, use the CTRL + / zoom in and out of options. If my optimum zoom level is used for all my browsing unless I change it.
I listed 2 modules below for you to consider. I did not use of NoSquint, but I use and rely on Default FullZoom Level.
- You can set a default zoom level in Options DFZL
- You can use the scroll wheel of the mouse on the icon Add on DFZL bar to increase or decrease the zoom or click the icon and choose from the available zoom percentages.
- In NoSquint, it is said that he recorded the zoom level of the web page/site.
- Default FullZoom Level: https://addons.mozilla.org/en-US/firefox/addon/default-fullzoom-level/
- NoSquint: https://addons.mozilla.org/en-US/firefox/addon/nosquint/
- More information about NoSquint: http://urandom.ca/nosquint/

How can I set a time stamp for the setCreationDate(Date value)?
Hi all
My underlying database column has a DATE data type that needs of the data and the time stamp. When you use the following code to set a date for setCreationDate(Date value) the date is set, but there is no timestamp.
Here is the code:
protected void create (AttributeList attributeList) {}
Super.Create (AttributeList);
Begin
Date currentDate = new Date();
DATE creationDate = currentDate.getCurrentDate ();
setCreationDate ((Date) creationDate);
End
}
Can't wait to hear.

How can I set up Vista so that the PC does not switch to another window (for example the Spy Sweeper alerts) while I am playing a game?
Vista is not in control of this technique. Spy Sweeper needs to have an option to control that. If this isn't the case, then it is badly programmed. Flight of focus (go to another window) when it is actually needed is a big no-no for the design. I find this option, if I were you :)

How can I set Adobe Reader as my default application to open PDF files?
I am a user of Mac with OS 10.5.8. The default application for PDF files found.
Often when I get a PDF file, I can't see the content. It comes in white... except, perhaps for the letterhead. I have to convert the 9.5 drive Adobe to be able to view the file.
How can I set my preferences so that Adobe Reader is the default application for PDF files?
Thank you.
I am answering my own question. I learned that if you right-click while trying to open a PDF file, you will be asked which application you want to use to open the file. If you click read the information, instead of choosing an application, you get this great information box that gives you the ability to set Adobe Reader in your default application for PDF files. It lets you change all the pdf files, you already have the Adobe files. Yay.

How can I set a few seconds from the beach to the specific level of db?
Hi all, I'm new to this software,
I want to know how can I put a few seconds from the beach to the specific level of db?
For example, I just want the maximum dB higher and the low dB to be only 3.
the sound is more concentrated.
How can I do?
Ah, you mean compression. There are several tools in hearing that, and one to use depends on the source material. If it is spoken word, then you can use dynamic processing tool (the original), the single band compressor or, possibly, the leveller speech volume to achieve this goal. If it's music, then the multiband compressor is rather sweet.
But with each of them, there is something important, you should firstly to your track, and it is to normalize it to 0 dB using Effects > Amplitude and Compression > Normalize. You should do this because all compressor settings are associated with a full range signal (i.e., 0 dB) to treat. If you do not do this, none of the controls will make sense. On your screen that you've expanded the display to make it much larger than it should be, then you might want to get back to normal, otherwise you will not see clearly what is happening. Hearing can artificially display any amplitude of the signal at all, due to floating-point processing system internal use, but in the real world, the audio device cannot handle more than 0 dB, please make sure that the signals exceed this.
