• Date type in oracle does not include time values

  - by Matt

  I have a PHP application using an Oracle XE database. Whenever I add a date the hours minutes, and seconds seem to get left out. Is there some special format, or type I should use to be able to store this? I have tried using to_date, and specifying the format I am using. Many thanks for any suggestions from this confused MySql dveloper.

• How do I reference an instance of a class using its tag?

  - by Matt Winters

  I have several instances of a UIControl class Foo being instantiated, one instance corresponding to each cell in a UITableView. The Class has: BOOL selected; UIImageView *imageView; UIImage *imageOne; UIImage *imageTwo; I've assigned each instance a tag: foo.tag = indexPath.row; I would now like to reference the UIImageView.image for a (or several) specific instance(s) by its tag to switch it to the other image. In my search I've seen things like classes being assigned tags using initWithTag (I assume they're assigning tags)... SomeClass *someClass = [[SomeClass alloc]initWithTag:1 ... [someArray addObject: [[SomeClass alloc]initWithTag:2 ... [someArray addObject: [[SomeClass alloc]initWithTag:3 ... ...but I haven't seen how they are later referenced by that tag. I have seen a reference to getChildByTag which had promise, but I can't find it in the documentation or examples (maybe not iphone). Does anyone know how reference the imageView.image within an instance using its tag? Thanks

• How suitable is a DVCS for the corporate environment?

  - by Matt Brailsford

  I've been using SVN for some time now, and am pretty happy with how it works (but I can't say I'm an expert, and I haven't really done much with branches and merging). However an opportunity has arisen to put in some new practises on a new team and so I thought I'd take a look at DVCSs to see if it's worth making the jump. The company I work for is a pretty standard company where we all work in the same location (or sometimes at home) and we want to keep a central store of all code. My question is: if all you are doing with a DVCS is creating a central hub that everyone pushes their changes to, is there really any benefit to moving to a DVCS and its extra overheads in this sort of environment?

• What programming languages/platforms can read XML documents?

  - by matt

  I'm working on a class assignment that involves reading an XML document and inserting the contents into a database. Language choice is wide open - so I figure, why not consider all my options! What languages are able and appropriate for the reading of XML?

• Need some ideas on how to acomplish this in Java (parsing strings)

  - by Matt

  Sorry I couldn't think of a better title, but thanks for reading! My ultimate goal is to read a .java file, parse it, and pull out every identifier. Then store them all in a list. Two preconditions are there are no comments in the file, and all identifiers are composed of letters only. Right now I can read the file, parse it by spaces, and store everything in a list. If anything in the list is a java reserved word, it is removed. Also, I remove any loose symbols that are not attached to anything (brackets and arithmetic symbols). Now I am left with a bunch of weird strings, but at least they have no spaces in them. I know I am going to have to re-parse everything with a . delimiter in order to pull out identifiers like System.out.print, but what about strings like this example: Logger.getLogger(MyHash.class.getName()).log(Level.SEVERE, After re-parsing by . I will be left with more crazy strings like: getLogger(MyHash getName()) log(Level SEVERE, How am I going to be able to pull out all the identifiers while leaving out all the trash? Just keep re-parsing by every symbol that could exist in java code? That seems rather lame and time consuming. I am not even sure if it would work completely. So, can you suggest a better way of doing this?

• Possible to implement an IsViewPortVisible dependencyproperty for an item in an ItemsControl?

  - by Matt H.

  I need to enable/disable spell checking in a richtextbox in an ItemsControl, based on whether the RichTextBox is visible in the ItemsControl's Scrollviewer. I think the route is to implement an IsViewPortVisible dependency property and wire an event handler for a changed event... I found this article that describes the lengthy process for determining if an item is in the viewport: http://social.msdn.microsoft.com/Forums/en/wpf/thread/e6ccfec3-3dc0-4702-9d0d-1cfa55ecfc90 Any ideas on where to start? I'm familiar with implementing my own dependency property for the sake of simple bindings (integers, strings, etc...). I have no idea how to undergo something like this though) This is the end result I'm hoping for: <DataTemplate> <Grid> ...Stuff in the Grid <local:CustomRichTextBox SpellCheck.IsEnabled={Binding RelativeSource={RelativeSource Self}, Path=IsViewPortVisible}/> </Grid> </DataTemplate> Help will be EXTREMELY appreciated... you'll be saving me about 500MB in memory consumption while the program is running!!!! :)

• Java Equivalent of C++ .dll?

  - by Matt D

  So, I've been programming for a while now, but since I haven't worked on many larger, modular projects, I haven't come across this issue before. I know what a .dll is in C++, and how they are used. But every time I've seen similar things in Java, they've always been packaged with source code. For instance, what would I do if I wanted to give a Java library to someone else, but not expose the source code? Instead of the source, I would just give a library as well as a Javadoc, or something along those lines, with the public methods/functions, to another programmer who could then implement them in their own Java code. For instance, if I wanted to create a SAX parser that could be "borrowed" by another programmer, but (for some reason--can't think of one in this specific example lol) I don't want to expose my source. Maybe there's a login involved that I don't want exploited--I don't know. But what would be the Java way of doing this? With C++, .dll files make it much easier, but I have never run into a Java equivalent so far. (I'm pretty new to Java, and a pretty new "real-world" programmer, in general as well)

• Help getting the following create table function to work with mysql and C#

  - by Matt

  string createTable = "CREATE TABLE IF NOT EXISTS " + m_strDatabase + "_TimeLogs (logName VARCHAR(16), logTime INTEGER, logCountry TEXT, UNIQUE(logName)) TYPE=MyISAM;"; When this runs, no table is created. No errors either. Im using an ODBC connector. the variable passes in the db name, so that the table created would be users_TimeLogs if the database was called users for example. Am I doing something wrong?

• WPF Datatemplate + ItemsControl each item uses > 1 MB Memory?

  - by Matt H.

  Does that sound right to anyone???? I have an ItemsControl that displays data from a custom object that implements iNotifyPropertyChanged. The DataTemplate consists of: Border 3 buttons 5 textboxes An ellipse A Bindable RichTextBox (custom class that inherits from RichTextBox... so I could make Document a dependency property (to support binding)) Several grids and stackpanels for layout It uses: Styles (stored in a resource dictionary higher up the tree) Styles affect: colors, thicknesses, and text properties: which are data-bound to a "settings" class that implements iNotifyPropertyChanged, so the user can change display settings That's it! So what gives? I've also noticed that when I empty and remove the ItemsControl, memory isn't freed. over 5000 instances of "CommandBindingCollection" and "WeakReference" are CREATED (using ANTS profiler). And huge number of EffectiveValueEntry objects are created too. So really, what gives!!! :-) Thanks for your insight! Management needs this project soon but in its current state, it's unreleasable.

• How to use Split with jQuery?

  - by Matt

  I need to break apart a string that always looks like this: something -- something_else. I need to put "something_else" in another input field. Currently, this string example is being added to an HTML table row on the fly like this: tRow.append($('<td>').text($('[id$=txtEntry2]').val())); I figure "split" is the way to go but there is very little documentation that I can find yet.

• My java program seems to be skipping over the try{}, executing the catch{} and then throwing a NullPointerException. What should I do?

  - by Matt Bolopue

  I am writing a program that calculates the number of words, syllables, and sentences in any given text file. I don't need help finding those numbers, however my program (which currently should only find the number of words in the text file) will not import the text file even when I type in the name of the file correctly. The text file is in the same folder as the source code. Instead it tells me every time that what I typed in has the wrong file extension (see my catch{}) and then proceeds to throw a null pointer. I am at a loss for what could be causing it. Any suggestions? import java.io.*; import java.util.*; public class Reading_Lvl_Calc { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub int words = 0; String fileName; Scanner scan; Scanner keyread = new Scanner(System.in); System.out.println("Please enter a file name (or QUIT to exit)"); fileName = keyread.nextLine(); File doc = new File(fileName); //while(scan.equals(null)){ try { scan = new Scanner(doc); } catch(Exception e) { if(fileName.substring(fileName.indexOf(".")) != ".txt") System.out.println("I'm sorry, the file \"" + fileName + "\" has an invalid file extension."); else System.out.println("I am sorry, the file \"" + fileName + " \" cannot be found.\n The file must be in the same directory as this program"); scan = null; } // } while(scan.hasNext()){ words++; scan.next(); } System.out.println(words); } }

• Deleting from 2 arrays of dictionaries

  - by Matt Winters

  I have an array of dictionaries loaded from a plist (below) called arrayHistory. <plist version="1.0"> <array> <dict> <key>item</key> <string>1</string> <key>result</key> <string>8.1</string> <key>date</key> <date>2009-12-15T19:36:59Z</date> </dict> ... </array> </plist> I filter this array based on 'item' so that a second array, arrayHistoryDetail has the same structure as arrayHistory but only contains e.g. 'item's equal to '1'. These detail items are successfully displayed in a tableView. I then want to select an item from the tableView, and delete it from the tableView data source, arrayHistoryDetail (line 2 in the code below) - works, then I want to delete the item from the tableView itself (line 3 in the code below) - also works. My problem is that I also need to delete it from the original arrayHistory, so I tried the following: created a temporary dictionary as an ivar: NSMutableDictionary *tempDict; @property (nonatomic, retain) NSMutableDictionary *tempDict; Then my thinking was to make a copy in line 1 and remove it from the original array in line 4. 1 tempDict = [arrayHistoryDetail objectAtIndex: indexPath.row]; 2 [arrayHistoryDetail removeObjectAtIndex: indexPath.row]; 3 [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; 4 [arrayHistory removeObject:tempDict]; Didn't work. Could someone please guide me in the right direction. I'm thinking that tempDict is a pointer and that removeObject needs a copy? I don't know. Thanks.

• What's the best approach to printing/reporting from WPF?

  - by Matt Hamilton

  I have an upcoming project which will have to be able to print simple reports from its data. It'll be WPF-based, and I'm wondering which way to go. I know that WPF introduces its own printing technology (based on XPS) which looks quite easy to use. However, part of me wonders whether it would just be easier to use the ReportViewer control and embed it in a Windows Forms host control, since that will give users the ability to export to a variety of formats as well as print. Has anyone had any experience with printing/reporting from WPF? Which direction would you recommend?

• Can you make an Extension Method Static/Shared?

  - by Matt Thrower

  OK, I've probably misunderstood something here but, as far as I can see ... An extension method has to be contained in a module, not a class You can't make methods in modules Static/Shared Therefore you can't use an extension method on a class without instantiating it. In other words you can't make an extension method on String called "MyExtensionMethod" and use: String.MyExtensionMethod("String") But instead .. Dim test As String test.MyExtensionMethod("string") Is this correct? Or is there a way I can get extension methods to work as static methods?

• android.intent.action.NOTIFICATION_REMOVE not available on all devices?

  - by Matt McMinn

  I've got a receiver set up in my android application to catch android.intent.action.NOTIFICATION_REMOVE intents. On my Evo, it works fine - when a notification is cleared from the notification bar, I catch that event and can run some code. I tried running this on a Samsung Moment though, and it is never caught. So now I'm trying to figure out why, and I can't seem to find anything on Google about this intent action - and I set this code up a few months ago, so I don't remember where I even found this action, it doesn't seem to be in the API. The evo is running 2.2, and the moment is running 2.1-update1, so I'm guessing that it's undocumented, and only available in 2.2. Is there any other way to catch an event that a notification has been cleared? Note that I'm not trying to cancel a notification that I put up, or trying to cancel another app's notification, just catch an event when a notification has been cleared. Here's my receiver in AndroidManafest.xml: <receiver android:name=".NotificationClearedReciever"> <intent-filter> <action android:name="android.intent.action.NOTIFICATION_REMOVE" /> </intent-filter> </receiver>

  I know how to show an alert when the user exits the browser and I know how to implement a neat modal dialog using the jQuery UI library. My problem is, I'd like to implement that dialog when the user attempts to close the browser rather than display the ugly little popup box. Is this do-able?

  IN VS2008, for C#, How can I figure out which references are needed and which are not? If you look in the solution explorer for a certain project and expand the references folder, is there a way to tell those that are never called? Will this be determined at compile time and simply not included?

• Which display manager for a non interactive Python app and mplayer?

  - by Matt

  I am developing an application that will run on Linux to run fullscreen all the time (no menus or trays or anything will be visible). The application is going to be developed in Python, not that that matters as far as the display manager, but what I am having a hard time with is choosing a display manager. I need something with the smallest possible footprint, that will let me run a graphical Python app and have an mplayer window at the same time, at widescreen resolutions (widescreen, 16:10,16:9, etc). Other than that, it doesn't need a lot of features, but the end footprint size is the most important thing I'll be looking at. What display manager would you recommend?

• Working with Foreign languages

  - by Matt

  My DB needs to hold strings containing foreign language characters such that; User enters string into form, form submitted and string added to DB, string will be displayed on page for viewing. I would like to use UTF8 as this will be able to handle all of the required languages. Currently I believe my DB is set to 'latin1' but webpages are capable of displaying correct charachters anyways. Problems arise when trying to set textareas to hold foreign charachters and when viewing DB via command-line. How can I implement this most effectively? My plan was to blitz the whole site such that:DB Charset is UTF8 and web pages charset is UTF8. Could someone give me the minimal commands on how to do this so I don't end up duplicating things (Having "UTF8" commands everywhere when I really just need one) and making things too difficult to control. Newbie Thanks
