  • Getting text after URL in asp.net / URL Rewriting (sort of!)

    - by alex
    My app is a very simple "one page" type app- It has Default.aspx I'm basically trying to get, for example: www.myappurl.com/this is my text I want to get hold of "this is my text" from the above example. This will be displayed on the page (for now) I didn't really want to have to use any complext url rewriting things for this... (My hosting provider uses IIS6) I tried using a 404 handler, but this is a bit long winded, and i'm using shared hosting, that can't set the "execute url" on custom 404 pages. Any other ideas?

  • Tool that auto-generate a code for accesing a xml-file

    - by alex
    My application have a configuration xml-file. That file contains more than 50 program settings. At the present time I read and save each program setting separately. I guess It is not effi?iently for such tasks. I need something that can auto-generate a code for load and save my program settings using predefined xml-schema. I found a dataset in Add New Item dialog. Unfortunately, i cannot add new code to dataset1 such as events in set-accessors of properties because of this // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. Maybe, there is a tool that allows a user to generate a wrapper for accesing a xml-file ? Such as DataSet1, but with availability to add events.

  • How to deal with a Java serialized object whose package changed?

    - by Alex
    I have a Java class that is stored in an HttpSession object that's serialized and transfered between servers in a cluster environment. For the purpose of this explanation, lets call this class "Person". While in the process of improving the code, this class was moved from "com.acme.Person" to "com.acme.entity.Person". Internally, the class remains exactly the same (same fields, same methods, same everything). The problem is that we have two sets of servers running the old code and the new code at the same time. The servers with the old code have serialized HttpSession object and when the new code unserializes it, it throws a ClassNotFoundException because it can't find the old reference to com.acme.Person. At this point, it's easy to deal with this because we can just recreate the object using the new package. The problem then becomes that the HttpSession in the new servers, will serialize the object with the new reference to com.acme.entity.Person, and when this is unserialized in the servers running the old code, another exception will be thrown. At this point, we can't deal with this exception anymore. What's the best strategy to follow for this kind of cases? Is there a way to tell the new servers to serialize the object with the reference to the old package and unserialize references to the old package to the new one? How would we transition to using the new package and forgetting about the old one once all servers run the new code?

  • codeigniter and form action trailing / issue??

    - by alex
    Hi, I am having a bit of an issue with the way CI is dealing with /. In a regular form i notice that the following form action didn't work action="mydomain.com/ci-controller/login/" but this one does work action="mydomain.com/ci-controller/login" Strange but he it worked. But now i need this from a iframe, i the iframe i have a login form which sets the parents url to mydomain.com/ci-controller/login, but i get the same error as it was calling mydomain.com/ci-controller/login/ Could my problem be that the call from the iframe adds a trailing / which is not visible?? Any thoughts

  • Android Video Camera : still picture

    - by Alex
    I use the camera intent to capture video. Here is the problem: If I use this line of code, I can record video. But onActivityResult doesn't work. Intent intent = new Intent("android.media.action.VIDEO_CAMERA"); If I use this line of code, after press the recording button, the camera is freezed, I mean, the picture is still. Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); BTW, when I use $Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); to capture a picture, it works fine. The java file is as follows: package com.camera.picture; import java.io.File; import java.text.SimpleDateFormat; import java.util.Date; import android.app.Activity; import android.content.ContentValues; import android.content.Intent; import android.net.Uri; import android.os.Bundle; import android.os.Environment; import android.provider.MediaStore; import android.util.Log; import android.view.View; import android.widget.Button; import android.widget.ImageView; import android.widget.Toast; import android.widget.VideoView; public class PictureCameraActivity extends Activity { private static final int IMAGE_CAPTURE = 0; private static final int VIDEO_CAPTURE = 1; private Button startBtn; private Button videoBtn; private Uri imageUri; private Uri videoUri; private ImageView imageView; private VideoView videoView; /** Called when the activity is first created. * sets the content and gets the references to * the basic widgets on the screen like * {@code Button} or {@link ImageView} */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); imageView = (ImageView)findViewById(R.id.img); videoView = (VideoView)findViewById(R.id.videoView); startBtn = (Button) findViewById(R.id.startBtn); startBtn.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { startCamera(); } }); videoBtn = (Button) findViewById(R.id.videoBtn); videoBtn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub startVideoCamera(); } }); } public void startCamera() { Log.d("ANDRO_CAMERA", "Starting camera on the phone..."); String fileName = "testphoto.jpg"; ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, fileName); values.put(MediaStore.Images.Media.DESCRIPTION, "Image capture by camera"); values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg"); imageUri = getContentResolver().insert( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); startActivityForResult(intent, IMAGE_CAPTURE); } protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == IMAGE_CAPTURE) { if (resultCode == RESULT_OK){ Log.d("ANDROID_CAMERA","Picture taken!!!"); imageView.setImageURI(imageUri); } } if (requestCode == VIDEO_CAPTURE) { if (resultCode == RESULT_OK) { Log.d("ANDROID_CAMERA","Video taken!!!"); Toast.makeText(this, "Video saved to:\n" + data.getData(), Toast.LENGTH_LONG).show(); videoView.setVideoURI(videoUri); } } } private void startVideoCamera() { // TODO Auto-generated method stub //create new Intent Log.d("ANDRO_CAMERA", "Starting camera on the phone..."); String fileName = "testvideo.mp4"; ContentValues values = new ContentValues(); values.put(MediaStore.Video.Media.TITLE, fileName); values.put(MediaStore.Video.Media.DESCRIPTION, "Video captured by camera"); values.put(MediaStore.Video.Media.MIME_TYPE, "video/mp4"); videoUri = getContentResolver().insert( MediaStore.Video.Media.EXTERNAL_CONTENT_URI, values); Intent intent = new Intent("android.media.action.VIDEO_CAMERA"); //Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, videoUri); intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); // start the Video Capture Intent startActivityForResult(intent, VIDEO_CAPTURE); } private static File getOutputMediaFile() { // TODO Auto-generated method stub // To be safe, you should check that the SDCard is mounted // using Environment.getExternalStorageState() before doing this.

  • mysql_affected_rows() returns 0 for UPDATE statement even when an update actually happens

    - by Alex Moore
    I am trying to get the number of rows affected in a simple mysql update query. However, when I run this code below, PHP's mysql_affected_rows() always equals 0. No matter if foo=1 already (in which case the function should correctly return 0, since no rows were changed), or if foo currently equals some other integer (in which case the function should return 1). $updateQuery = "UPDATE myTable SET foo=1 WHERE bar=2"; mysql_query($updateQuery); if (mysql_affected_rows() > 0) { echo "affected!"; } else { echo "not affected"; // always prints not affected } The UPDATE statement itself works. The INT gets changed in my database. I have also double-checked that the database connection isn't being closed beforehand or anything funky. Keep in mind, mysql_affected_rows doesn't necessarily require you to pass a connection link identifier, though I've tried that too. Details on the function: mysql_affected_rows Any ideas? SOLUTION The part I didn't mention turned out to be the cause of my woes here. This PHP file was being called ten times consecutively in an AJAX call, though I was only looking at the value returned on the last call, ie. a big fat 0. My apologies!

  • Normalizing a table

    - by Alex
    I have a legacy table, which I can't change. The values in it can be modified from legacy application (application also can't be changed). Due to a lot of access to the table from new application (new requirement), I'd like to create a temporary table, which would hopefully speed up the queries. The actual requirement, is to calculate number of business days from X to Y. For example, give me all business days from Jan 1'st 2001 until Dec 24'th 2004. The table is used to mark which days are off, as different companies may have different days off - it isn't just Saturday + Sunday) The temporary table would be created from a .NET program, each time user enters the screen for this query (user may run query multiple times, with different values, table is created once), so I'd like it to be as fast as possible. Approach below runs in under a second, but I only tested it with a small dataset, and still it takes probably close to half a second, which isn't great for UI - even though it's just the overhead for first query. The legacy table looks like this: CREATE TABLE [business_days]( [country_code] [char](3) , [state_code] [varchar](4) , [calendar_year] [int] , [calendar_month] [varchar](31) , [calendar_month2] [varchar](31) , [calendar_month3] [varchar](31) , [calendar_month4] [varchar](31) , [calendar_month5] [varchar](31) , [calendar_month6] [varchar](31) , [calendar_month7] [varchar](31) , [calendar_month8] [varchar](31) , [calendar_month9] [varchar](31) , [calendar_month10] [varchar](31) , [calendar_month11] [varchar](31) , [calendar_month12] [varchar](31) , misc. ) Each month has 31 characters, and any day off (Saturday + Sunday + holiday) is marked with X. Each half day is marked with an 'H'. For example, if a month starts on a Thursday, than it will look like (Thursday+Friday workdays, Saturday+Sunday marked with X): ' XX XX ..' I'd like the new table to look like so: create table #Temp (country varchar(3), state varchar(4), date datetime, hours int) And I'd like to only have rows for days which are off (marked with X or H from previous query) What I ended up doing, so far is this: Create a temporary-intermediate table, that looks like this: create table #Temp_2 (country_code varchar(3), state_code varchar(4), calendar_year int, calendar_month varchar(31), month_code int) To populate it, I have a union which basically unions calendar_month, calendar_month2, calendar_month3, etc. Than I have a loop which loops through all the rows in #Temp_2, after each row is processed, it is removed from #Temp_2. To process the row there is a loop from 1 to 31, and substring(calendar_month, counter, 1) is checked for either X or H, in which case there is an insert into #Temp table. [edit added code] Declare @country_code char(3) Declare @state_code varchar(4) Declare @calendar_year int Declare @calendar_month varchar(31) Declare @month_code int Declare @calendar_date datetime Declare @day_code int WHILE EXISTS(SELECT * From #Temp_2) -- where processed = 0) BEGIN Select Top 1 @country_code = t2.country_code, @state_code = t2.state_code, @calendar_year = t2.calendar_year, @calendar_month = t2.calendar_month, @month_code = t2.month_code From #Temp_2 t2 -- where processed = 0 set @day_code = 1 while @day_code <= 31 begin if substring(@calendar_month, @day_code, 1) = 'X' begin set @calendar_date = convert(datetime, (cast(@month_code as varchar) + '/' + cast(@day_code as varchar) + '/' + cast(@calendar_year as varchar))) insert into #Temp (country, state, date, hours) values (@country_code, @state_code, @calendar_date, 8) end if substring(@calendar_month, @day_code, 1) = 'H' begin set @calendar_date = convert(datetime, (cast(@month_code as varchar) + '/' + cast(@day_code as varchar) + '/' + cast(@calendar_year as varchar))) insert into #Temp (country, state, date, hours) values (@country_code, @state_code, @calendar_date, 4) end set @day_code = @day_code + 1 end delete from #Temp_2 where @country_code = country_code AND @state_code = state_code AND @calendar_year = calendar_year AND @calendar_month = calendar_month AND @month_code = month_code --update #Temp_2 set processed = 1 where @country_code = country_code AND @state_code = state_code AND @calendar_year = calendar_year AND @calendar_month = calendar_month AND @month_code = month_code END I am not an expert in SQL, so I'd like to get some input on my approach, and maybe even a much better approach suggestion. After having the temp table, I'm planning to do (dates would be coming from a table): select cast(convert(datetime, ('01/31/2012'), 101) -convert(datetime, ('01/17/2012'), 101) as int) - ((select sum(hours) from #Temp where date between convert(datetime, ('01/17/2012'), 101) and convert(datetime, ('01/31/2012'), 101)) / 8) Besides the solution of normalizing the table, the other solution I implemented for now, is a function which does all this logic of getting the business days by scanning the current table. It runs pretty fast, but I'm hesitant to call a function, if I can instead add a simpler query to get result. (I'm currently trying this on MSSQL, but I would need to do same for Sybase ASE and Oracle)

  • I have a bunch of template parameters that I want to hide from my users. How can I do this?

    - by Alex
    I have a superclass which is defined in terms of a few internal types it uses. Subclassing is performed as so: template <class InternalType1, class InternalType2> class Super { ... } class Sub : Super <interalTypeClass1, interalTypeClass2> { ... } But when I want to write a function that takes a pointer to the superclass, this happens : template <class InternalType1, class InternalType2> void function(Super<InternalType1, InternalType2>* in) { ... } The user really shouldn't know anything about the inside classes, and should really just concern himself with the use of the function. Some of these template lists become very very large, and expecting the user to pass them every time is wasteful, in my opinion. Any suggestions? EDIT: The function needs to know the internal types in use, so unless there is a way to access template types at compile time, I think there is no solution? Potential solution: Have each class do the following: #define SubTemplateArgs <SubTypeName, SubInternalType1, SubInternalType2> ?

  • How can I disable the F4 key from showing the items in a ComboBox

    - by Alex
    You might not know this, but pressing the F4 key on a ComboBox makes it's drop-down item list appear. I believe this is the default behavior on Windows. Does anyone know how to override this behavior in WPF (C#)? I know that overriding default behavior is generally seen as bad practice, however in this case I have a rugged-device that runs XP Embedded. It has a handful of prominent Function keys (F1-F6) that need to trigger different events. This works fine, however when focused over a ComboBox the events aren't triggered as the ComboBox drops down. I have tried catching the KeyDown event both on the form and on the ComboBox and listening for the F4 key, however it doesn't get this far as the key press must be handled at a lower level. Any ideas? Thanks.

  • Why does Eclipse crash with Xmx, XX:MaxPermSize above certain values?

    - by alex
    Running Eclipse 3.5.1, JDK 1.6.0_17 on WinXP SP3 32Bit with 3.5 gigs of RAM. I'm aware of the known Eclipse best practices, still trying to figure out eclipse.ini. This will launch: -Xmx588m and this won't: -Xmx589m. Same with -XX:MaxPermSize. Anything above -XX:MaxPermSize=140m won't launch. The screen of death is simlar to this (taken from here). Any ideas on why might this be happening?

  • Nested <ul><li> navigation menu using a recursive Python function

    - by Alex
    Hi. I want to render this data structure as an unordered list. menu = [ [1, 0], [2, 1], [3, 1], [4, 3], [5, 3], [6, 5], [7,1] ] [n][0] is the key [n][1] references the parent key The desired output is: <ul> <li>Node 1</li> <ul> <li>Node 2</li> <li>Node 3</li> <ul> <li>Node 4</li> <li>Node 5</li> <ul> <li>Node 6</li> </ul> </ul> <li>Node 7</li> </ul> </ul> I could probably do this without recursion but that would be no fun. Unfortunately, I am having problems putting it all together. I don't have much experience with recursion and this is proving to be very difficult for me to build and debug. What is the most efficient way to solve this problem in Python? Thanks!

  • Is it so bad to have heaps of elements in your DOM?

    - by alex
    I am making a real estate non interactive display for their shop window. I have kicked jCarousel into doing what I want: Add panels per AJAX Towards the end of the current set, go and AJAX some new panels and insert them This works fine, but it appears calling jQuery's remove() on the prior elements cause an ugly bump. I'm not sure if calling hide() will free up any resources, as the element will still exist (and the element will be off screen anyway). I've seen this, and tried carousel.reset() from within a callback. It just clears out all the elements. This will be running on Google Chrome on Windows XP, and will solely by displaying on LCD televisions. I am wondering, if I can't find a reasonable solution to remove the extra DOM elements, will it bring my application to a crawl, or will Chrome do some clever garbage collecting? Or, how would you solve this problem? Thanks

  • Generic applet style system for publishing mathematics demonstrations?

    - by Alex
    Anyone who's tried to study mathematics using online resources will have come across these Java applets that demonstrate a particular mathematical idea. Examples: http://www.math.ucla.edu/~tao/java/Mobius.html http://www.mathcs.org/java/programs/FFT/index.html I love the idea of this interactive approach because I believe it is very helpful in conveying mathematical principles. I'd like to create a system for visually designing and publishing these 'mathlets' such that they can be created by teachers with little programming experience. So in order to create this app, i'll need a GUI and a 'math engine'. I'll probably be working with .NET because thats what I know best and i'd like to start experimenting with F#. Silverlight appeals to me as a presentation framework for this project (im not worried about interoperability right now). So my questions are: does anything like this exist already in full form? are there any GUI frameworks for displaying mathematical objects such as graphs & equations? are there decent open source libraries that exposes a mathematical framework (Math.NET looks good, just wondering if there is anything else out there) is there any existing work on taking mathematical models/demos built with maple/matlab/octave/mathematica etc and publishing them to the web?

  • Reference table values in a war against magic numbers

    - by Alex N.
    This question bugged me for years now and can't seem to find good solution still. I working in PHP and Java but it sounds like this maybe language-agnostic :) Say we have a standard status reference table that holds status ids for some kind of entity. Further let's assume the table will have just 5 values, and will remain like this for a long time, maybe edited occasionally with addition of a new status. When you fetch a row and need to see what status it is you have 2 options(as I see it at least) - put it straight ID values(magic numbers that is) or use a named constant. Latter seem much cleaner, the question though is where those named constants should leave? In a model class? In a class that uses this particular constant? Somewhere else?

  • [C#] Running elevated applications on user login with UAC?

    - by Alex
    I need to start a program every time the user logs in, but I cannot do this without being met by a UAC dialog asking for permissions for that application. Is there any way to have an application start up on user login without the user having to answer the UAC prompt? I was thinking about running a service, but this would be a last resort. I saw something about an Application Compatibility Toolkit to disable UAC for certain applications, but I feel this is too big of a hassle - even services would be easier to program. I was just wondering if there is an even easier solution I am missing. Thanks in advance.

  • jQuery select image in div if image parent does't have a certain class.

    - by Alex
    Wordpress wraps images with captions in a div with a class of .wp-caption. I'm looking for a way to select images that don't have this div so I can wrap them in different div. (to keep a consistent border around all the images) <div class="blog-post-content"> <div id="attachment_220" class="wp-caption alignleft" style="width: 310px"> <a href="/somewhere/"><img class="size-medium wp-image-220" src="/path/to/image" alt="" width="300" height="280" /></a> <p class="wp-caption-text">Caption Text</p> </div> <p>This is the body of the post</p> </div> To test my selector, I'm just trying to add a green border. I can handle the .wrap() once the selector is working. The most promising of my attempts is: $('.blog-post-content img').parent('div:not(".wp-caption")').css('border', '2px solid green'); ... but no luck.
