What's a good way to teach my son to program Java

- by Software Monkey

OK, so I've read through various posts about teaching beginner's to program, and there were some helpful things I will look at more closely. But what I want to know is whether there are any effective tools out there to teach a kid Java specifically? I want to teach him Java specifically because (a) with my strong background in C I feel that's too complex, (b) Java is the other language I know extremely well and therefore I can assist meaningfully without needing to teach myself a new but (to me) useless language, and (c) I feel that managed languages are the future, and lastly (d) Java is one of the simplest of all the languages I know well (aside from basic). I learned in basic, and I am open to teaching that first, but I am unaware of a decent free basic shell for Windows (though I haven't really searched, yet since it's not my first choice), and would anyway want to progress quickly to Java. My son is 8, so that's a couple of years earlier than I started - but he has expressed an interest in learning to program (possibly because I work from home a lot and he sees me programming all the time). If no-one can suggest a tool designed for this purpose, I will probably start him off with text/console based apps to teach the basics, and then progress to GUI building. Oh, one last thing, I am not a fan of IDE's (old school text editor type), so I would not be put off at all by a system that has him typing real code, and would likely prefer that to a toy drag/drop system. EDIT: Just to clarify; I really am specifically after ways to teach him Java; there are already a good many posts with good answers for other language alternatives - but that's not what I am looking for here. EDIT: What about Java frameworks for 2D video games - can anyone recommend any of them from personal experience? I like the idea of him starting with the mechanics in place (main game loop, scoring, etc) and adding the specifics for a game of his own imagining - that's what I did, though for me it was basic on a Commodore VIC-20 and a Sinclair ZX-81.

Pause code execution until UIAlertView button is pressed?

- by JuBu1324

One of my methods sends a message to an object (what do you know about that), and expects a BOOL for an answer. However, BOOL answer it is expecting is based on the answer to a UIAlertView created in the receiving object's method. However, the code doesn't pause while waiting for the user to answer the UIAlertView. My problem is: how do I use -alertView:clickedButtonAtIndex in the method's return value? Here's the code the message runs (in this construction, I was expecting navigateAwayFromTab to change based on the user input in the UIAlertView, but it never gets a chance): - (BOOL)readyToNavigateAwayFromTab { NSLog( @"message received by Medical View"); navigateAwayFromTab = NO; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Navigate Away From Tab?" message:@"Navigating away from this tab will save your work." delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil ]; [alert show]; [alert release]; return navigateAwayFromTab; } #define CANCEL 0 #define OK 1 - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if( buttonIndex == OK ) navigateAwayFromTab = YES; } I've been reading up on the modal UIAlertView debate, and I agree with apple's implementation - at lest as the rule. However, in this case I don't see any way of solving the problem by putting code in -alertView:clickedButtonAtIndex because I don't need to run code based on the UIAlertView, I just need to read the response. Any suggestions on how I can reach my gaol? I've tried a while loop after [alert show] already, but then the alert doesn't even show then, and for a number of reasons I can't use -viewWillDisapear.

iteration in latex

Hi, I would like to use some iteration control flow to simplify the following latex code \begin{sidewaystable} \caption{A glance of images} \centering \begin{tabular}{| c ||c| c| c |c| c|| c |c| c|c|c| } \hline \backslashbox{Theme}{Class} &\multicolumn{5}{|c|}{Class 0} & \multicolumn{5}{|c|}{Class 1} \\ \hline \hline 1 & \includegraphics[scale=2]{../../results/1/0_1.eps} &\includegraphics[scale=2]{../../results/1/0_2.eps} &\includegraphics[scale=2]{../../results/1/0_3.eps} &\includegraphics[scale=2]{../../results/1/0_4.eps} &\includegraphics[scale=2]{../../results/1/0_5.eps} &\includegraphics[scale=2]{../../results/1/1_1.eps} &\includegraphics[scale=2]{../../results/1/1_2.eps} &\includegraphics[scale=2]{../../results/1/1_3.eps} &\includegraphics[scale=2]{../../results/1/1_4.eps} &\includegraphics[scale=2]{../../results/1/1_5.eps} \\ \hline \hline 2 & \includegraphics[scale=2]{../../results/2/0_1.eps} &\includegraphics[scale=2]{../../results/2/0_2.eps} &\includegraphics[scale=2]{../../results/2/0_3.eps} &\includegraphics[scale=2]{../../results/2/0_4.eps} &\includegraphics[scale=2]{../../results/2/0_5.eps} &\includegraphics[scale=2]{../../results/2/1_1.eps} &\includegraphics[scale=2]{../../results/2/1_2.eps} &\includegraphics[scale=2]{../../results/2/1_3.eps} &\includegraphics[scale=2]{../../results/2/1_4.eps} &\includegraphics[scale=2]{../../results/2/1_5.eps} \\ \hline ... % similarly for 3, 4, ..., 22 \hline 23 & \includegraphics[scale=2]{../../results/23/0_1.eps} &\includegraphics[scale=2]{../../results/23/0_2.eps} &\includegraphics[scale=2]{../../results/23/0_3.eps} &\includegraphics[scale=2]{../../results/23/0_4.eps} &\includegraphics[scale=2]{../../results/23/0_5.eps} &\includegraphics[scale=2]{../../results/23/1_1.eps} &\includegraphics[scale=2]{../../results/23/1_2.eps} &\includegraphics[scale=2]{../../results/23/1_3.eps} &\includegraphics[scale=2]{../../results/23/1_4.eps} &\includegraphics[scale=2]{../../results/23/1_5.eps} \\ \hline \end{tabular} \end{sidewaystable} I learn that the forloop package provides the for loop. But I am not sure how to apply it to my case? Or other methods not by forloop? Thanks and regards! Update: If I also want to simply another similar case, where the only difference is that the directory does not run from 1, 2, to 23, but in some arbitrary order such as 3, 2, 6, 9,..., or even a list of strings such as dira, dirc, dird, dirb,.... How to make the latex code into loops then? Thanks!

Adding new record to a VFP data table in VB.NET with ADO recordsets

- by Gerry

I am trying to add a new record to a Visual FoxPro data table using an ADO dataset with no luck. The code runs fine with no exceptions but when I check the dbf after the fact there is no new record. The mDataPath variable shown in the code snippet is the path to the .dbc file for the entire database. A note about the For loop at the bottom; I am adding the body of incoming emails to this MEMO field so thought I needed to break the addition of this string into 256 character Chunks. Any guidance would be greatly appreciated. cnn1.Open("Driver={Microsoft Visual FoxPro Driver};" & _ "SourceType=DBC;" & _ "SourceDB=" & mDataPath & ";Exclusive=No") Dim RS As ADODB.RecordsetS = New ADODB.Recordset RS.Open("select * from gennote", cnn1, 1, 3, 1) RS.AddNew() 'Assign values to the first three fields RS.Fields("ignnoteid").Value = NextIDI RS.Fields("cnotetitle").Value = "'" & mail.Subject & "'" RS.Fields("cfilename").Value = "''" 'Looping through 254 characters at a time and add the data 'to Ado Field buffer For i As Integer = 1 To Len(memo) Step liChunkSize liStartAt = i liWorkString = Mid(mail.Body, liStartAt, liChunkSize) RS.Fields("mnote").AppendChunk(liWorkString) Next 'Update the recordset RS.Update() RS.Requery() RS.Close()

codingbat wordEnds using regex

- by polygenelubricants

I'm trying to solve wordEnds from codingbat.com using regex. This is the simplest as I can make it with my current knowledge of regex: public String wordEnds(String str, String word) { return str.replaceAll( String.format( ".*?(?=%s)(?<=(.|^))%1$s(?=(.|$))|.+", java.util.regex.Pattern.quote(word) ), "$1$2" ); } String.format is used to inject word into the pattern for both readability and convenience (it's injected twice). Pattern.quote isn't necessary to pass their tests, but I think it's required for a proper regex-based solution. The regex has two major parts: If after matching as few characters as possible ".*?", word can still be found "(?=%s)", then lookbehind to capture any character immediately preceding it "(?<=(.|^))", match word "%1$s" and lookforward to capture any character following it "(?=(.|$))". The initial "if" test ensures that the atomic lookbehind captures only if there's a word Using lookahead to capture the following character doesn't consume it, so it can be used as part of further matching Otherwise match what's left "|.+" Groups 1 and 2 would capture empty strings I think this works in all cases, but it's obviously quite complex. I'm just wondering if others can suggest a simpler regex to do this. Note: I'm not looking for a solution using indexOf and a loop. I want a regex-based replaceAll solution. I also need a working solution that I can just copy-paste into codingbat and passes.

Getting an Error Trying to Create an Object in Python

MVC Multiple submit buttons on a array of objects

- by Kieron

Hi, I've got a list of objects in an MVC view, each with a set of submit buttons - Move up, Move down and Remove. Using the answer from this question, I can get the button clicked - but I need to know which item it would be operating on. The problem comes from the fact the input's value attribute is passed back, I need more information than that - i.e. an id. Below is a snippet of the contents of a for loop, rendering each item. <ul> <li><input type="submit" name="SubmitButton" value="Move-Up" class="linked-content-position-modifier" /></li> <li><input type="submit" name="SubmitButton" value="Move-Down" class="linked-content-position-modifier" /></li> <li><input type="submit" name="SubmitButton" value="Remove" class="linked-content-modifier" /></li> <li><%= Model.Contents[i] %></li> </ul> When the form is posted back, I can see that the SubmitButton has a value of either Move-Up, Move-Down or Remove - but no idea which item in the array it's referring too. Without changing the value to something really ugly, how would I tell which item it's referring to?

Iterating arrays in a batch file

- by dboarman-FissureStudios

I am writing a batch file (I asked a question on SU) to iterate over terminal servers searching for a specific user. So, I got the basic start of what I'm trying to do. Enter a user name Iterate terminal servers Display servers where user is found (they can be found on multiple servers now and again depending on how the connection is lost) Display a menu of options Iterating terminal servers I have: for /f "tokens=1" %%Q in ('query termserver') do (set __TermServers.%%Q) Now, I am getting the error... Environment variable __TermServers.SERVER1 not defined ...for each of the terminal servers. This is really the only thing in my batch file at this point. Any idea on why this error is occurring? Obviously, the variable is not defined, but I understood the SET command to do just that. I'm also thinking that in order to continue working on the iteration (each terminal server), I will need to do something like: :Search for /f "tokens=1" %%Q in ('query termserver') do (call Process) goto Break :Process for /f "tokens=1" %%U in ('query user %%username%% /server:%%Q') do (set __UserConnection = %%C) goto Search However, there are 2 things that bug me about this: Is the %%Q value still alive when calling Process? When I goto Search, will the for-loop be starting over? I'm doing this with the tools I have at my disposal, so as much as I'd like to hear about PowerShell and other ways to do this, it would be futile. I have notepad and that's it. Note: I would continue this line of questions on SuperUser, except that it seems to be getting more into programming specifics.

C#: How to force "calling" a method from the main thread by signaling in some way from another thread

- by Fire-Dragon-DoL

Sorry for long title, I don't know even the way on how to express the question I'm using a library which run a callback from a different context from the main thread (is a C Library), I created the callback in C# and when gets called I would like to just raise an event. However because I don't know what will be inside the event, I would like to find a way to invoke the method without the problem of locks and so on (otherwise the third party user will have to handle this inside the event, very ugly) Are there any way to do this? I can be totally on the wrong way but I'm thinking about winforms way to handle different threads (the .Invoke thing) Otherwise I can send a message to the message loop of the window, but I don't know a lot about message passing and if I can send "custom" messages like this Example: private uint lgLcdOnConfigureCB(int connection, System.IntPtr pContext) { OnConfigure(EventArgs.Empty); return 0U; } this callback is called from another program which I don't have control over, I would like to run OnConfigure method in the main thread (the one that handles my winform), how to do it? Or in other words, I would like to run OnConfigure without the need of thinking about locks

jquery stop image rotation on mouseover, start on mouseout / hover

- by Matt Nathanson

I have built a jQuery rotator to rotate through 3 divs and loop them. I would like to add the functionality on mouse over to "freeze" the current div and then start again on mouse out. I've thought about setting a variable to false at the start of the function and setting it true when it's on it's current frame but I've got my self a bit confused. I've also tried to use the hover function but when using the in and out handlers, I'm confused as to how to stop, restart the animation. function ImageRotate() { var CurrentFeature = "#container" + featureNumber; $(CurrentFeature).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); var featureNumber2 = featureNumber+1; if ( featureNumber == numberOfFeatures) {featureNumber2 = 1} var NewFeature = "#container" + featureNumber2; $(NewFeature).stop(false, true).delay(4500).animate({'top' : '0px'}, 3000); var featureNumber3 = featureNumber-1; if ( featureNumber == 1) {featureNumber3 = numberOfFeatures}; var OldFeature = "#container" + featureNumber3; $(OldFeature).stop(false, true).delay(4500).css('top' , '-330px'); setTimeout('if (featureNumber == numberOfFeatures){featureNumber = 1} else {featureNumber++}; ImageRotate2()', 7500)}; Any help would be greatly appreciated!!

jquery ajax call from link loaded with ajax

The problem I'm having is some content loads with links which are intended to load content into a secondary window. I'm using the .live() method to allow jquery to listen for new links loaded into the primary content div. This works until the .ajax() method is called for these fresh links loaded with ajax, where the method begins, but follows the original link before data can be received. I'm assuming the problem is in the client-side scripting, but it may be a problem with the call made to the server. I'm using the wordpress loop to parse the url and generate the html loaded via jquery. Thanks for any tips!

Occasionally, when someone is using my app, it'll force close with this exception: java.lang.ArrayIndexOutOfBoundsException at android.widget.AbsListView$RecycleBin.addScrapView(AbsListView.java:3572) at android.widget.AbsListView.trackMotionScroll(AbsListView.java:2487) at android.widget.AbsListView.onTouchEvent(AbsListView.java:2001) at android.widget.ListView.onTouchEvent(ListView.java:3234) at android.view.View.dispatchTouchEvent(View.java:3709) at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:874) at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:924) at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:924) at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:924) at com.android.internal.policy.impl.PhoneWindow$DecorView.superDispatchTouchEvent(PhoneWindow.java:1695) at com.android.internal.policy.impl.PhoneWindow.superDispatchTouchEvent(PhoneWindow.java:1116) at android.app.Activity.dispatchTouchEvent(Activity.java:2068) at com.android.internal.policy.impl.PhoneWindow$DecorView.dispatchTouchEvent(PhoneWindow.java:1679) at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:924) at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:924) at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:924) at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:924) at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:924) at com.android.internal.policy.impl.PhoneWindow$DecorView.superDispatchTouchEvent(PhoneWindow.java:1695) at com.android.internal.policy.impl.PhoneWindow.superDispatchTouchEvent(PhoneWindow.java:1116) at android.app.Activity.dispatchTouchEvent(Activity.java:2068) at com.android.internal.policy.impl.PhoneWindow$DecorView.dispatchTouchEvent(PhoneWindow.java:1679) at android.view.ViewRoot.handleMessage(ViewRoot.java:1697) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:4568) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) at dalvik.system.NativeStart.main(Native Method) However, I cannot figure out why. It's relatively rare, non-reproducable, and the stacktrace is completely unhelpful because it doesn't include any of my code. Is it a bug in Android itself?

SQL Quey slow in .NET application but instantaneous in SQL Server Management Studio

- by user203882

Here is the SQL SELECT tal.TrustAccountValue FROM TrustAccountLog AS tal INNER JOIN TrustAccount ta ON ta.TrustAccountID = tal.TrustAccountID INNER JOIN Users usr ON usr.UserID = ta.UserID WHERE usr.UserID = 70402 AND ta.TrustAccountID = 117249 AND tal.trustaccountlogid = ( SELECT MAX (tal.trustaccountlogid) FROM TrustAccountLog AS tal INNER JOIN TrustAccount ta ON ta.TrustAccountID = tal.TrustAccountID INNER JOIN Users usr ON usr.UserID = ta.UserID WHERE usr.UserID = 70402 AND ta.TrustAccountID = 117249 AND tal.TrustAccountLogDate < '3/1/2010 12:00:00 AM' ) Basicaly there is a Users table a TrustAccount table and a TrustAccountLog table. Users: Contains users and their details TrustAccount: A User can have multiple TrustAccounts. TrustAccountLog: Contains an audit of all TrustAccount "movements". A TrustAccount is associated with multiple TrustAccountLog entries. Now this query executes in milliseconds inside SQL Server Management Studio, but for some strange reason it takes forever in my C# app and even timesout (120s) sometimes. Here is the code in a nutshell. It gets called multiple times in a loop and the statement gets prepared. cmd.CommandTimeout = Configuration.DBTimeout; cmd.CommandText = "SELECT tal.TrustAccountValue FROM TrustAccountLog AS tal INNER JOIN TrustAccount ta ON ta.TrustAccountID = tal.TrustAccountID INNER JOIN Users usr ON usr.UserID = ta.UserID WHERE usr.UserID = @UserID1 AND ta.TrustAccountID = @TrustAccountID1 AND tal.trustaccountlogid = (SELECT MAX (tal.trustaccountlogid) FROM TrustAccountLog AS tal INNER JOIN TrustAccount ta ON ta.TrustAccountID = tal.TrustAccountID INNER JOIN Users usr ON usr.UserID = ta.UserID WHERE usr.UserID = @UserID2 AND ta.TrustAccountID = @TrustAccountID2 AND tal.TrustAccountLogDate < @TrustAccountLogDate2 ))"; cmd.Parameters.Add("@TrustAccountID1", SqlDbType.Int).Value = trustAccountId; cmd.Parameters.Add("@UserID1", SqlDbType.Int).Value = userId; cmd.Parameters.Add("@TrustAccountID2", SqlDbType.Int).Value = trustAccountId; cmd.Parameters.Add("@UserID2", SqlDbType.Int).Value = userId; cmd.Parameters.Add("@TrustAccountLogDate2", SqlDbType.DateTime).Value =TrustAccountLogDate; // And then... reader = cmd.ExecuteReader(); if (reader.Read()) { double value = (double)reader.GetValue(0); if (System.Double.IsNaN(value)) return 0; else return value; } else return 0;

C++ Set Erase Entry Question

- by Wallace

Hi. I encountered a problem here. I'm using C++ multiset. This is the test file. Score: 3-1 Ben Steven Score: 1-0 Ben Score: 0-0 Score: 1-1 Cole Score: 1-2 Ben I'm using while loop and ifstream (fin1) to read in from the test file above. multiset<string, less<string> > myset; while(!fin1.eof()) { fin1 >> scoreName; if(scoreName == "Score:") { //calculates number of matches played } else { goalCheck = scoreName.substr(1,1); if(goalCheck == "-") { string lGoal, rGoal; lGoal = scoreName.substr(0,1); rGoal = scoreName.substr(2,1); int leftGoal, rightGoal; leftGoal = atoi(lGoal.c_str()); rightGoal = atoi(rGoal.c_str()); if(leftGoal > rightGoal) //if team wins { //some computations } else if(leftGoal < rightGoal) //if team loses { //computations } else if(leftGoal == rightGoal) //if team draws { //computations } else { myset.insert(myset.begin(), scoreName); } } } I'm inserting all names into myset (regardless of wins/loses/draws) in my last else statement. But I only require the names of those matches who won/draw. Those names whose matches lost will not be included in myset. In the test file above, there's only one match that lost (1-2) and I wanted to remove "Ben". How can I do that? I tried to use myset.erase(), but I'm not sure how to get it point to Ben and remove it from myset. Any help is much appreciated. Thanks.

How to mass insert/update in linq to sql?

- by chobo2

Hi How can I do these 2 scenarios. Currently I am doing something like this public class Repository { private LinqtoSqlContext dbcontext = new LinqtoSqlContext(); public void Update() { // find record // update record // save record ( dbcontext.submitChanges() } public void Insert() { // make a database table object ( ie ProductTable t = new ProductTable() { productname ="something"} // insert record ( dbcontext.ProductTable.insertOnSubmit()) // dbcontext.submitChanges(); } } So now I am trying to load an XML file what has tons of records. First I validate the records one at a time. I then want to insert them into the database but instead of doing submitChanges() after each record I want to do a mass submit at the end. So I have something like this public class Repository { private LinqtoSqlContext dbcontext = new LinqtoSqlContext(); public void Update() { // find record // update record } public void Insert() { // make a database table object ( ie ProductTable t = new ProductTable() { productname ="something"} // insert record ( dbcontext.ProductTable.insertOnSubmit()) } public void SaveToDb() { dbcontext.submitChanges(); } } Then in my service layer I would do like for(int i = 0; i < 100; i++) { validate(); if(valid == true) { update(); insert() } } SaveToDb(); So pretend my for loop is has a count for all the record found in the xml file. I first validate it. If valid then I have to update a table before I insert the record. I then insert the record. After that I want to save everything in one go. I am not sure if I can do a mass save when updating of if that has to be after every time or what. But I thought it would work for sure for the insert one. Nothing seems to crash and I am not sure how to check if the records are being added to the dbcontext.

Objective-C : Fowler–Noll–Vo (FNV) Hash implementation

- by Dough

Hi ! I have a HTTP connector in my iPhone project and queries must have a parameter set from the username using the Fowler–Noll–Vo (FNV) Hash. I have a Java implementation working at this time, this is the code : long fnv_prime = 0x811C9DC5; long hash = 0; for(int i = 0; i < str.length(); i++) { hash *= fnv_prime; hash ^= str.charAt(i); } Now on the iPhone side, I did this : int64_t fnv_prime = 0x811C9DC5; int64_T hash = 0; for (int i=0; i < [myString length]; i++) { hash *= fnv_prime; hash ^= [myString characterAtIndex:i]; } This script doesn't give me the same result has the Java one. In first loop, I get this : hash = 0 hash = 100 (first letter is "d") hash = 1865261300 (for hash = 100 and fnv_prime = -2128831035 like in Java) Do someone see something I'm missing ? Thanks in advance for the help !

embedding layout inside each tab? - (each tab has its own activity)

- by Abhi

I have started with the HelloTabwidget example and it works fine. Now what I am trying to do is have a layout inside each tab. here is what the code looks like myApp extends TabActivity { TabHost tabHost; onCreate() { setContentView (R.layout.main); tabHost = getTabHost(); TabHost.tabspec spec = tabHost.newTabSpec(..).setIndicator(...). setContent(new Intent().setClass(...)); tabHost.addTab(spec); : } } myTab1Actvity extends Activity { ListView myLV; EditText myET; onCreate() { setcontentView (TAB1_LAYOUT); myLV = findViewById(..); : myLV.setAdapter(aa); myET.setOnKeyListener(....) registerforContextMenu(myLV) } } when I run here is the stack trace ERROR/AndroidRuntime(691): java.lang.NullPointerException ERROR/AndroidRuntime(691): at android.widget.TabHost.dispatchWindowFocusChanged(TabHost.java:295) ERROR/AndroidRuntime(691): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:661) ERROR/AndroidRuntime(691): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:661) ERROR/AndroidRuntime(691): at android.widget.TabHost.dispatchWindowFocusChanged(TabHost.java:295) ERROR/AndroidRuntime(691): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:661) ERROR/AndroidRuntime(691): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:661) ERROR/AndroidRuntime(691): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:661) ERROR/AndroidRuntime(691): at android.view.ViewRoot.handleMessage(ViewRoot.java:1819) ERROR/AndroidRuntime(691): at android.os.Handler.dispatchMessage(Handler.java:99) ERROR/AndroidRuntime(691): at android.os.Looper.loop(Looper.java:123) ERROR/AndroidRuntime(691): at android.app.ActivityThread.main(ActivityThread.java:4363) ERROR/AndroidRuntime(691): at java.lang.reflect.Method.invokeNative(Native Method) ERROR/AndroidRuntime(691): at java.lang.reflect.Method.invoke(Method.java:521) ERROR/AndroidRuntime(691): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) ERROR/AndroidRuntime(691): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) Does the code's flow look OK? basically each Tab has its own activity and each tab has its own layout. It appears that something is wrong in the TabHost - but I am unable to pinpoint it. Any suggestions/Qs you hav e will be very helpful.

Flex, Ant, mxmlc and conditional compilation

- by Rezmason

My ActionScript project builds with several compile-time specified constants. They are all Booleans, and only one of them is true at any given time. The rest must be false. When I represented my build process in a bash script, I could loop through the names of all these constants, set one of them to be true and the rest to be false, then concatenate them onto a string to be inserted as a set of arguments passed to mxmlc. In Ant, looping is more complicated. I've tried the ant-contrib for tag: <mxmlc file='blah' output='blah'> <!- ... -> <for list='${commaSeparatedListOfConstNames}' param='constName'> <sequential> <define> <name>${constName}</name> <value>${constName} == ${theTrueConst}</value>  </define> </sequential> </for> </mxmlc> Long story short, ant-contrib tags like the for tag can't go in the mxmlc task. So now I'm using Ant's propertyregex to take my list of arguments and format them into a set of define args, like my old bash script: <propertyregex property='defLine.first' override='false' input='${commaSeparatedListOfConstNames}' regexp='([^\|]+)\,' replace='\1,false ' /> <propertyregex property='defLine.final' input='${defLine.first}' regexp='(@{theTrueConst}\,)false' replace='\1true' />  Now my problem is, what can I do with this mxmlc argument and the mxmlc task? Apparently arg tags can go inside the mxmlc task without it throwing an error, but they don't seem to have any effect. What am I supposed to do? How do I make this work with the mxmlc task?

Creating Array of settings names and values using ADO.NET Entities

- by jordan.baucke

I'm using an ADO.NET Entities (.edmx) data-model along with MVC2 to build an application. I have a DB table where I want to store settings for method that run elsewhere. MVC2 allows me to create a view, editor, etc. to update this table which is great, but now when I want to do simple assignments based on column titles I'm a bit confused. For example, I would like to easily build an array that I could offset into the record's value based on it's "Title" Column: var entities = new ManagerEntities(); Setting[] settings = entities.settings.ToArray(); This returns something like: Settings[0].[SettingTitle][SettingValue] However, I would like to more easily index into the value than having to loop through all the returned settings, when they're already index. string URL_ID_NEED = [NeededUrl][http://www.url.com] Am I missing something relatively simple? Thanks! ========================= *Update* ========================= Ok, I think I've got a solution, but I'm wondering why this would be so complicated, and if I'm just not thinking of the right context for ADO.NET objects, here's what I did: public string GetSetting(string SettingName) { var entities = new LabelManagerEntities(); IEnumerable<KeyValuePair<string, object>> entityKeyValues = new KeyValuePair<string, object>[] { new KeyValuePair<string, object>("SettingTitle", SettingName) }; EntityKey key = new EntityKey("LabelManagerEntities.Settings", entityKeyValues); // Get the object from the context or the persisted store by its key. Setting settingvalue = (Setting)entities.GetObjectByKey(key); return settingvalue.SettingValue.ToString(); } This method handles the job of querying the Entities by "Key" to get back the correct value as a returned string (which I can than strip out the " ", or or cast to an integer, etc. etc.,) Am I just duplicating functionality that already exists in ADO.NET's design patterns (I'm pretty new to it) -- or is this a reasonable solution?
