Rendering and viewer technology in mobile apps like GrabCAD?

Any idea about what rendering engine or viewer is being used in CAD mobile application such as GrabCAD mobile App?

They have rolled out both iOS and Andriod applications and I am curious to know what is the technology behind this appication..

Are they using any commercial engines such as HOOPS or something else or is it built directly on top of OpenGL?

I have a client in Canada who I'm doing a WPF project for. He has decided that he wants certain portions to run on their Samsung Tablet 7.

I am a Windows developer. I know absolutely NOTHING about tablet or android development.

1) What tools do I need?

2) Can anyone recommend a good entry level book?

Thanks

If it's not broken, fix it until it is

If you are using SQLiteOpenHelper object then database will be permanent.Two helper methods onCreate (To create DB when it does not exists) and onUpdate (used when db exists but has different version) are available.

Refer http://developer.android.com/reference/android/database/sqlite/SQLiteOpenHelper.html[^] to know more about SQLiteOpenHelper.

Hello,

I had the same problem. Please see my code and description below:

Data base initialization:

Java

private SQLiteDatabase _mySqlLiteDataBase = MyActivity.this.openOrCreateDatabase("MyDataBaseName", Context.MODE_PRIVATE, null);

Please note that method name is: openOrCreateDatabase.
This mean that it will only create your database if it does not exists.

Hope this will help.

Qustion about scheduling of RTOS

econy28-Jun-13 8:27

econy

28-Jun-13 8:27

I have a question about the scheduling of RTOS, assume I have 10 tasks, each task consumes 3 ms cpu time.

And each task has the folloing structure:

xxTask() {

,,,,

While(true) {

delay(50ms);

Statement 1;

do task things;

Statement 100;

}

}

My question is, if there were no interrupts, only tasks exists in the context, is the scheduling rule of RTOS let each task run a whole loop? i.e, from statement1 to statement 100. Assume all tasks have the same priority, and they are started at the same time.

is there possibility the task runs like:

task1: statement1...statement50; -> task5:statement20 ... statement96; -> task10:statment90->statment100;

that is to say, undetermined, for example: sometimes, one task can run a whole loop, from statement1 to statement100; sometimes, one task run from statementXX to statementYY;

Emergency Popup Notifications

RJOberg21-Jun-13 5:34

21-Jun-13 5:34

I'm looking at possibly developing an application that pushes emergency alerts to specific users. I've seen a number of solutions available for purchase, but nothing quite fits the entire list of what we want, plus it will have to be cross-platform. So while SMS would be the easiest delivery method, I am unaware of any way to make an SMS message which appears in the method we desire.

Most of the requirements they have are easy enough and are things I have done in the past. The problem I am having is creating alerts that are pushed to the device that override anything else the user is doing, outside of using it to make a phone call. This will be used for true emergencies, not kittens up trees. So not a normal push notification.

Anyone in the US who has a smart phone that lives in an area with inclement weather has likely gotten the alerts from the National Weather Service, advising of tornadoes, floods, etc. Which pop up and take up the entire screen with the alert, information about what is going on, plus make noise until you acknowledge the alert, or a predetermined amount of time has passed. At which point the noise stops but the alert retains focus. Even if the screen goes into hibernation, the alert remains when you turn it back on.

I haven't found any documentation on how to do this. Does anyone have any experience with this level of push alert or any idea where to start looking for how to do so? My luck with Google has provided some examples, but nothing quite right. I want this to be mildly obnoxious, impossible to miss, and require user feedback to go away. We want to make certain the user sees the alert.

Thanks in advance.

So basically in the mobile app i change the host name in the db connection to that of the website instead of using 'localhost' like i normally do. Is that what you are saying?

Hello,

In that case you do not need to connect to the web application's database. Further in a poduction environment nobody is going to expose the database in a such a way that it can be directly accessed over internet. The best way to access the data is to create the web services and access those. Following CP articles will get you started in creating web services.

USB Latency specifications

29-May-13 10:43

I'm reading an eBook.

I think the software is screwing things up.

i.e., what I see on my screen can't be right.

The endpoint descriptor stored in the device specifies the maximum latency period.  For low-speed devices, the maximum latency can be any value from 10--255 ms.  For full speed, the range is 1--255 ms. for high speed and SuperSpeed, the range is 125 Ms to 4.096 s in increments of 125 Ms. In addition, a high-speed or SuperSpeed  interrupt endpoint with a maximum latency of 125 Ms can request 1, 2, or 3 transactions per interval.

I'm assuming that that capital "M" character is supposed to be the greek "mu" letter, i.e.,

(10)**(-6)

or (I hope I count the zeros properly) 0.000125 seconds.

Somebody tell me yes or no. I think the number is supposed to be 125 MicroSeconds.
