  • Extract two double Values from String using RegEx in Java

    - by tzippy
    I am reading a file by line and need to extract latitude and longitude from it. This how lines can looks: DE 83543 Rott am Inn Bayern BY Oberbayern Landkreis Rosenheim 47.983 12.1278 DE 21147 Hamburg Hamburg HH Kreisfreie Stadt Hamburg 53.55 10 What's for sure is, there are no dots surrounded by digits except for the ones representing the doubles. Unfortunately there are Values without a dot, so it's probably best to check for numbers from the end of the String. thanks for your help!

  • How do I programmatically trigger a mx:Button click event?

    - by knorv
    Consider the following mx:Button: <mx:Button click="doSomething()" id="myButton"/> Is there some way to programmatically emulate the user clicking the button? One obvious way to do it would simply be to call doSomething() which would give the same end result as clicking the button. But I'm specifically looking for ways to emulate the click -- that is something along the lines of myButton.click() (if that should have existed).

  • get attributes from xml tree using linq

    - by nelsonwebs
    I'm working with an xml file that looks like this: <?xml version="1.0" encoding="UTF-8"?> <element1 xmlns="http://namespace1/"> <element2> <element3> <element4 attr1="2009-11-09"> <element5 attr2="NAME1"> <element6 attr3="1"> <element7 attr4="1" attr5="5.5" attr6="3.4"/> </element6> </element5> <element5 attr2="NAME2"> <element6 attr3="1"> <element7 attr4="3" attr5="4" attr6="4.5"/> </element6> </element5> </element4> </element3> </element2> </element1> Where I need to loop through element5 and retrieve the attributes in an Ienumberable like this: attr1, attr2, attr3, attr4, attr5, attr6 using linq to xml and c#. I can loop through the element5 and get all the attribute2 info using but I can't figure out how to get the parent or child attributes I need. UPDATE: Thanks for the feeback thus far. For clarity, I need to do a loop through attribute5. So basically, what I have right now (which isn't much) is . . . XElement xel = XElement.Load(xml); IEnumberable<XElement> cList = from el in xel.Elements(env + "element2").Element (n2 + "element3").Elements(n2 + "element4").Elements(ns + "element5") select el; foreach (XElement e in cList) Console.WriteLine(e.Attribute("attr2").Value.ToString()); This will give me the value all the attr 2 in the loop but I could be going about this all wrong for what I'm trying to acheive. I also need to collect the other attributes mentioned above in a collection (the Console reference is just me playing with this right now but the end result I need is a collection). So the end results would be a collection like attr1, attr2, attr3, attr4, attr5, attr6 2009-11-09, name1, 1, 1, 5.5, 3.4 2009-11-09, name2, 1, 3, 4, 4.5 Make Sense?

  • Need Help Loading and Manipulating Bitmap Data

    - by Dave
    Using VB6, I need to load a bitmap image and subsequently manipulate some of its data - specifically, I want to rotate a section within the image, and in the end keep the image intact with the rotated section. How do I (1) find out where an image gets loaded into memory (a physical address), and (2) in what format is it stored, a 1-D array, 2-D array, or what? Maybe you can even suggest a better way to do this. Thanks.

    Hi guys, i would like to know if there's something wrong in this asp.net code: mydatareader = mycmd.executeReader() if myDataReader.HasRow then // Do something end if myConnection.Close() If i avoid to call a "MyDataReader.Close()" does the connection close anyway ?
