The program that I'm using (the external one) the most right enter key is ENTER (or RETURN) and the one above the shift is NEW LINE.

Hi guys,
I'm writing a Robot and wonder what is the command to press Enter (the key on the very right side, not the Enter above the shift).
The reason for this is because I have an application that the Enter (or Return) is only by the very right enter key.

Thanks!

// this is not the enter I'm looking for :-( robot.keyPress(KeyEvent.VK_ENTER); robot.keyRelease(KeyEvent.VK_ENTER);

Hi all,
I have a text data in which I need to extract the taxes (in the data below it's JC = 5.20, FS = 17.60). Those taxes change from state to state so it's not always JC, FS etc; and sometimes they don't even exists (system error) or there's only one tax (system error)
My task is to extract those taxes into a map<String,Double). One approach I thought of is to use matcher and patter and use in the compile: \s\w\w\s+\d+\.\d\d
I was wondering if there's a better approach?
Thanks!

Pattern p = Pattern.compile("\\s\\w\\w\\s+\\d+\\.\\d\\d");
[more data comes here] O/S Amt TX.C Tax 1/5 TX.C Tax 2/6 TX.C Tax 3/7 TX.C Tax 4/8 JC 5.20 FS 17.60 TR 7.03 PO 6.50 FOI/PTA WE 6.53 QW 64.85 FE 96.00 PFC Arpt/Amt1 PFC Arpt/Amt2 PFC Arpt/Amt3 PFC Arpt/Amt4 PFC Arpt/Amt5 POI 9.50 [more data comes here]

thank you both! it works.

Hi Guys,

I'm trying to write a pattern where a line should begin with a digit AND end with a digit. The problem that I face is that both conditions should occur together (starts with and ends with).

Can any one point how this should work? for code simplicity I need to write one pattern (not to use startsWith or endsWith)

Pattern pattern = Pattern.compile("^\\d\\d$"); //if used ^\\d it's ok and if used \\d$ it's ok but together they //don't work. Maybe should be something betweetn the ^\\d and the \\d$
Thanks

Hi Guys,

Can anyone point to an e-commerce open source? Specifically, I'm looking to build a shopping cart for a restaurant (a coffee shop) and wonder if anyone has any idea of where to start.

Thank you!

thanks for the input. Will surely buy the book! Thanks again.

Hi guys,

I'm a complete newbie in the field of iPhone development. I wonder if there's any way to develop an iPhone app using java (if so, which one and is it recommended to do so)?

Also, can anyone point at a site to start developing an app (either with obj-C or java)

My goal is to build an app that user can login using credentials and query a remote db.

thanks!!!

Thanks, so I can go to sleep with no worries?

Hi Guys,

We've been using mysql for quite some time (2yr) and learned that the size of the db tends to grow over time. Currently, if we dump my db we get a 3.2GB file. I'm aware that mySql can hold up to 4GB of data (I guess only on 32bit os).

If this continues, we may find that the db doesn't work properly anymore. What are the options we have? Can anyone advise/recommend what should we do in order to have the db working properly in the long run without the fear of running out of space? We store only TEXT! no photos/videos or any stream, text only!

*we're using hibernate

Thanks for any pointers.

Got it! thanks, using the SHIFT (this will not work on a non QWERTY keyboard) but that's not a problem on my end. THANKS!!!

Hi Guys,

I was wondering why in the following code the output is: "~%" and not "~!@#$%^&*()_+"

1. Open a textpad (before you run it)
2. Run the code
3. Go to the textpad and clickin (so the cursor is in the textpad)

Thanks

thank you all for the input!

A relatively 'abstract security question' how can I avoid users to manipulate the URL and circumvent a security permission?

Example, user clicks a link: https://localhost:8443/MyApp/userProfile_prepareProfile.do?userID=53122

In this example the parameter will be for user ID 53122 but what if the end user manipulates the URL and place userID=4444 (someone else).

I guess, one way to solve this is to encrypt the userID but wonder if there's a better way to do it (I'm using struts2)

Thanks!
