  • Is there a java library / package analogous to <stdio.h>?

    - by Roboprog
    I have been doing Java on and off for about 14 years, and almost nothing else the last 6 years or so. I really hate the java.io package -- its legion of subclasses and adapters. I do like exceptions, rather than having to always poll "errno" and the like, but I could surely live without declared exceptions. Is there anything that functions like the Unix/ANSI stdio.h routines in C? I know we will never be rid of java.io and its conventions until java itself is retired, as they have metastasized throughout the many frameworks that have accreted to java. That said, I would like something that works kind of like this (let's call it package javax.stdio): Have a main utility class, perhaps FileStar, that can read and write files (or pipes), either text or binary, either sequentially or random access, with constructors that mimic fopen() and popen(). This class should have a load of useful methods that do things like fread(), fwrite(), fgets(), fputs(), fseek(), and whatever else (fprintf()?). Methods that are incompatible with the open/construct mode simply throw up (just like some of the collections classes/methods do when restricted). Then, have a bunch of interfaces that suggest how you intend to use the stream once you have created it: Sequential, RandomAccess, ReadOnly, WriteOnly, Text, Binary, plus combinations of these that make sense. Perhaps even have methods to return the appropriate type-cast (interface), throwing up if you have asked for something incompatible. For extra flavor, skip the declared exceptions -- e.g. - javax.stdio.IOException extends RuntimeException. Is there an open source project like this floating around?

  • How to run unittest for Django?

    - by photon
    I configured properties for my django project under pydev. I can run the django app under pydev or under console window. But I have problems to run unittest under pydev. I cannot run unittest for app under console window either. I guessed it's something related to run configurations of pydev, so I made several trials, but with no success. Once I got messages like this: ImportError: Could not import settings 'D:\django_projects\MyProject' (Is it on sys.path? Does it have syntax errors?): No module named D:\django_projects\MyProject ERROR: Module: MyUnittestFile could not be imported. Another time I got messages like this: ImportError: Could not import settings 'MyProject.settngs' (Is it on sys.path? Does it have syntax errors?): No module named settngs 'ERROR: Module: MyUnittestFile could not be imported. I use pydev 1.5.6 on eclipse and windows xp. Any ideas for this problem? Now I think it's not something related to pydev, thanks for Xavier Ho's suggestion.

  • NSPredicate as a constraint solver?

    - by Felixyz
    I'm working on a project which includes some slightly more complex dynamic layout of interface elements than what I'm used to. I always feel stupid writing complex code that checks if so-and-so is close to such-and-such and in that case move it x% in some direction, etc. That's just not how programming should be done. Programming should be as declarative as possible! Precisely because what I'm going to do is fairly simple, I thought it would be a good opportunity to try something new, and I thought of using NSPredicate as a simple constraints solver. I've only used NSPredicate for very simple tasks so far, but I know that it capable of much more. Are there any ideas, experiences, examples, warnings, insights that could be useful here? I'll give a very simple example so there will be something concrete to answer. How could I use NSPredicate to solve the following constraints: viewB.xmid = (viewB.leftEdge + viewB.width) / 2 viewB.xmid = max(300, viewA.rightEdge + 20 + viewB.width/2) ("viewB should be horizontally centered on coordinate 300, unless its left edge gets within 20 pixels of viewB's right edge, in which case viewA's left edge should stay fixed at 20 pixels to the right of viewB's right edge and viewA's horizontal center get pushed to the right.") viewA.rightEdge and viewB.width can vary, and those are the 'input variables'. EDIT: Any solution would probably have to use the NSExpression method -(id)expressionValueWithObject:(id)object context:(NSMutableDictionary *)context. This answer is relevant.

  • Destructuring assignment in JavaScript

    - by Anders Rune Jensen
    As can be seen in the Mozilla changlog for JavaScript 1.7 they have added destructuring assignment. Sadly I'm not very fond of the syntax (why write a and b twice?): var a, b; [a, b] = f(); Something like this would have been a lot better: var [a, b] = f(); That would still be backwards compatible. Python-like destructuring would not be backwards compatible. Anyway the best solution for JavaScript 1.5 that I have been able to come up with is: function assign(array, map) { var o = Object(); var i = 0; $.each(map, function(e, _) { o[e] = array[i++]; }); return o; } Which works like: var array = [1,2]; var _ = assign[array, { var1: null, var2: null }); _.var1; // prints 1 _.var2; // prints 2 But this really sucks because _ has no meaning. It's just an empty shell to store the names. But sadly it's needed because JavaScript doesn't have pointers. On the plus side you can assign default values in the case the values are not matched. Also note that this solution doesn't try to slice the array. So you can't do something like {first: 0, rest: 0}. But that could easily be done, if one wanted that behavior. What is a better solution?

  • How can I speed up Subversion checkins? (Using ANKH, latest, Visual Studio 2010)

    - by Timothy Khouri
    I've started working on a new web project with some friends... we are using the latest Subversion server (installed last week), the latest version of ANKH. My web project is a whapping 1.5 megabytes (that's with all images, css files, dll's after compiling, pdb files... etc). Checking in even super small changes (literally adding the letter "x" to a few files for testing)... takes FOREVER! (about 10 seconds - I almost killed myself). The ANKH client is measuring in BYTES PER SECOND ... BYTES? per second... I must be doing something wrong. Does anyone what config file has a joke totallyMessWithPeople=true so that I can turn that off or something? Oh, also, changing one "big" file of a super 10k gains speed up to nearly the speed of light (which is apparently 857 bytes per second). Help me obi wan kenobi, your my only hope! EDIT: As a note... my real work project that uses Visual Source Safe 2005 (I know, ouch) uploads files at about 200-500kbps from this very same computer/internet connection.

  • Maven Mojo & SCM Plugin: Check for a valid working directory

    - by Patrick Bergner
    Hi there. I'm using maven-scm-plugin from within a Mojo and am trying to figure out how to determine if a directory D is a valid working directory of an SCM URL U (i.e. a checkout of U to D already happened). The context is that I want to do a checkout of U if D is a working set or do an update if it isn't. The plan is to check out U to D if D does not exist, update D if D is a valid working directory of U, display an error if D exists and is not a valid working directory of U. What I tried is to call ScmManager.status(), ScmManager.list() and ScmManager.changelog() and try to guess something from their results. But that didn't work. The results from status and changelog always return something positive (isSuccess() = true, getChangedFiles() = valid List, no exceptions to catch), whereas list throws an exception in any case. ScmRepository and ScmFileSet don't seem to provide suitable methods as well. An option would be to always do an update if D exists but then I cannot tell if it is a working directory of U or any SCM working directory at all. The ideal solution would be independent of the actual SCM system and a specific ScmVersion. Thanks for your help! Patrick

  • Confusion about WPF binding...

    - by Vladislav
    I am trying to bind a 2D array of buttons arranged in stackpanels to a 2D ObservableCollection... Yet, I'm afraid I don't understand something very elementary about binding. My XAML: <Window.Resources> <DataTemplate x:Key="ItemsAsButtons"> <Button Content="{Binding}" Height="100" Width="100"/> </DataTemplate> <DataTemplate x:Key="PanelOfPanels"> <ItemsControl ItemsSource="{Binding Path=DayNumbers}" ItemTemplate=" {DynamicResource ItemsAsButtons}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </DataTemplate> </Window.Resources> ... <ItemsControl x:Name="DaysPanel" Grid.ColumnSpan="7" Grid.Row="2" ItemTemplate="{DynamicResource PanelOfPanels}"/> My C# code: The backend: /// <summary> /// Window BE for Calendar.xaml /// </summary> public partial class Calendar : Window { private CalendarViewModel _vm; public Calendar() { InitializeComponent(); _vm = new CalendarViewModel(); this.DataContext = _vm; } } The ViewModel: class CalendarViewModel { CalendarMonth _displayedMonth; EventCalendar _calendar; public CalendarViewModel() { _displayedMonth = new CalendarMonth(); } public ObservableCollection<ObservableCollection<int>> DayNumbers { get { return _displayedMonth.DayNumbers; } } } I'm trying to populate the buttons with values from CalendarViewModel.DayNumbers - yet the buttons do not appear. I'm clearly doing something wrong with my binding.

  • Conditional macro expansion

    - by Dave DeLong
    Heads up: This is a weird question. I've got some really useful macros that I like to use to simplify some logging. For example I can do Log(@"My message with arguments: %@, %@, %@", @"arg1", @"arg2", @"arg3"), and that will get expanded into a more complex method invocation that includes things like self, _cmd, __FILE__, __LINE__, etc, so that I can easily track where things are getting logged. This works great. Now I'd like to expand my macros to not only work with Objective-C methods, but general C functions. The problem is the self and _cmd portions that are in the macro expansion. These two parameters don't exist in C functions. Ideally, I'd like to be able to use this same set of macros within C functions, but I'm running into problems. When I use (for example) my Log() macro, I get compiler warnings about self and _cmd being undeclared (which makes total sense). My first thought was to do something like the following (in my macro): if (thisFunctionIsACFunction) { DoLogging(nil, nil, format, ##__VA_ARGS__); } else { DoLogging(self, _cmd, format, ##__VA_ARGS__); } This still produces compiler warnings, since the entire if() statement is substituted in place of the macro, resulting in errors with the self and _cmd keywords (even though they will never be executed during function execution). My next thought was to do something like this (in my macro): if (thisFunctionIsACFunction) { #define SELF nil #define CMD nil } else { #define SELF self #define CMD _cmd } DoLogging(SELF, CMD, format, ##__VA_ARGS__); That doesn't work, unfortunately. I get "error: '#' is not followed by a macro parameter" on my first #define. My other thought was to create a second set of macros, specifically for use in C functions. This reeks of a bad code smell, and I really don't want to do this. Is there some way I can use the same set of macros from within both Objective-C methods and C functions, and only reference self and _cmd if the macro is in an Objective-C method?

  • Moral fits the story or suggest me a nice moral?

    - by Gobi
    A 25 year old son was sitting beside his old father in a train one day. When the train was about to leave, all the passengers started settling down in their seats. The son was filled with joy and anxiety. He was seated by the window. He put his hand out and felt the breeze and screamed, “ Papa look at all the trees, they are moving behind”. The old father smiled and admired his son’s feelings. Beside the old man, a couple was also travelling and observed this strange behavior. They found something awkward and childish in the behavior of this 25 year old man. All of a sudden, the son shouted again “Papa see! The clouds are moving about; there is a pond down and many cows are drinking it’s water”. It soon started drizzling. Once again, the young man felt exited and said “papa, I can see and feel the rain drops touching my hand”. The couple seeing this and feeling concerned, asked the old man “why don’t you consult a good doctor and treat your son; don’t you find something abnormally different in him ?” The old man replied, “Yes, I have provided the best treatment for my only boy. We are just returning from the hospital. I am happy for today is the day he has received his sense of sight. It’s for the first time my son is seeing and relishing these little wonders which we have been watching and ignoring in our routine life!” The couple had no words to reply and felt sorry for their remarks. Moral of the story: “ “don’t judge a book by its cover”. is this the moral fits the story or provide me some moral for this story :)

  • Table valued function only returns CLR error

    - by Anthony
    I have read-only access to a database that was set up for a third-party, closed-source app. Once group of (hopefully) useful table functions only returns the error: Failed to initialize the Common Language Runtime (CLR) v2.0.50727 with HRESULT 0x80131522. You need to restart SQL server to use CLR integration features. (severity 16) But in theory, the third-party app should be able to use the function (either directly or indirectly), so I'm convinced I'm not setting things up right. I'm very new to SQL Server, so I could be missing something obvious. Or I could be missing something really slight, I have no idea. Here is an example of a query that returns the above error: SELECT * FROM dbo.UncompressDataDateRange(4,'Apr 24 2010 12:00AM','Apr 30 2010 12:00AM') Where the function takes three parameters: The Data Set (int) -- basically the data has 6 classifications, and the giant table this should be pulling from has a column to indicate which is which. startDate (smalldatetime) endDate (smalldatetime) There are other, similar functions that expand on the same idea, all returning the same error. Quick Note: I'm not sure if this is relevant, but I was able to connect to the database via SQL Studio (but without the privs to script the functions as code), and a checked the dependency for the above sample function. It turns out that it is a dependent of a view that I have gotten to work, and that view is dependent of the larger, much-hairier data-table. This makes me think I should somehow be pointing the function at the results of the view, but I'm not seeing any documentation that shows how that is done.

  • Is it possible to have anonymous purchases with ubercart without the creation of a new user account?

    - by DKinzer
    I would like to be able to have anonymous users purchase a product but not have a new account created when they purchase it. Unfortunately the creation of a new user seems to be very tightly integrated into ubercart's ordering system. And, because the order module is part of the ubercart core, it's behavior cannot be overridden easily. One possibility for overriding is the creation of a new user account by supplying ubercart with an bogus anonymous account: hook into hook_form_alter at $form_id == 'uc_cart_checkout_review_form' because this is where ubercart first associates the $order to an uid. Add our submit function to the queue: //Find out if the user is anonymous: global $user; if ($user->uid == 0 ) { //Load a previously created anonymous user account $anonymous_user = mymodule_get_anonymous_user(); //create the order and assign our anonymous_user_id to it $order = uc_order_load($_SESSION['cart_order']); $order->uid = $anonymous_user->uid; uc_order_save($order); //Assign the global user our anonymous user uid $user->uid = $anonymous_user->uid; } But what I really need is to be able to have an anonymous purchase without being forced to create a new account, this solution does not work for me. Apart from which, using this technique will automatically login the anonymous_user into our bogus_anonymous_user account. Which is definitely something I don't want. Is there a better non-duct-tape way around the creation of a new user account for anonymous purchases in ubercart?. AND FYI - at this point I'm kind of stuck with ubercart so I cannot use something else. Thanks! D

  • Sanitizing user input that will later be e-mailed - what should I be worried about?

    - by Kevin Burke
    I'm interning for an NGO in India (Seva Mandir, http://sevamandir.org) and trying to fix their broken "subscribe to newsletter" box. Because the staff isn't very sophisticated and our web host isn't great, I decided to send the relevant data to the publications person via mail() instead of storing it in a MySQL database. I know that it's best to treat user input as malicious, and I've searched the SO forums for posts relevant to escaping user data for sending in a mail message. I know the data should be escaped; what should I be worried about and what's the best way to sanitize the input before emailing it? Form flow: 1. User enters email on homepage and clicks Submit 2. User enters name, address, more information on second page (bad usability, I know, but my boss asked me to) and clicks "Submit" 3. Collect the data via $_POST and email it to the publications editor (and possibly send a confirmation to the subscriber). I am going to sanitize the email in step 2 and the other data in step 3. I appreciate your help, Kevin

  • What's the best way to annotate this ggplot2 plot? [R]

    - by Matt Parker
    Here's a plot: library(ggplot2) ggplot(mtcars, aes(x = factor(cyl), y = hp, group = factor(am), color = factor(am))) + stat_smooth(fun.data = "mean_cl_boot", geom = "pointrange") + stat_smooth(fun.data = "mean_cl_boot", geom = "line") + geom_hline(yintercept = 130, color = "red") + annotate("text", label = "130 hp", x = .22, y = 135, size = 4) I've been experimenting with labeling the geom_hline in a few different ways, each of which does something I want but has a problem that the other methods don't have. annotate(), used above, is nice - the text is resizeable, black, and easy to position. But it can only be placed within the plot itself, not outside the plot like the axis labels. It also makes an "a" appear in the legend, which I can't dismiss with legend = FALSE. legend = FALSE works with geom_text, but I can't get geom_text to just be black - it seems to be getting tangled up in the line colorings. grid.text lets me put the text anywhere I want, but I can't seem to resize it. I can definitely accept the text being inside of the plot area, but I'd like to keep the legend clean. I feel like I'm missing something simple, but I'm just fried. Thanks in advance for your consideration.

  • How to make a big switch control structure with variable check values?

    - by mystify
    For example, I have a huge switch control structure with a few hundred checks. They're an animation sequence, which is numbered from 0 to n. Someone said I can't use variables with switch. What I need is something like: NSInteger step = 0; NSInteger i = 0; switch (step) { case i++: // do stuff break; case i++: // do stuff break; case i++: // do stuff break; case i++: // do stuff break; } The point of this is, that the animation system calls a method with this big switch structure, giving it a step number. I want to be able to simply cut-copy-paste large blocks and put them in a different position inside the switch. for example, the first 50 blocks to the end. I could do that easily with a huge if-else structure, but it would look ugly and something tells me switch is much faster. How to?

  • continueTrackingWithTouch: withEvent: not being called continuously.

    - by Steven Noyes
    I have a very simply subclass of UIButton that will fire off a custom event when the button has been held for 2 seconds. To accomplish this, I overrode: // // Mouse tracking // - (BOOL)beginTrackingWithTouch:(UITouch *)touch withEvent:(UIEvent *)event { [super beginTrackingWithTouch:touch withEvent:event]; [self setTimeButtonPressed:[NSDate date]]; return (YES); } - (BOOL)continueTrackingWithTouch:(UITouch *)touch withEvent:(UIEvent *)event { [super continueTrackingWithTouch:touch withEvent:event]; if ([[self timeButtonPressed] timeIntervalSinceNow] > 2.0) { // // disable the button. This will eventually fire the event // but this is just stubbed to act as a break point area. // [self setEnabled:NO]; [self setSelected:NO]; } return (YES); } My problem is (this is in the simulator, can't do on device work quite yet) "continueTrackingWithTouch: withEvent:" is not being called unless the mouse is actually moved. It does not take much motion, but it does take some motion. By returning "YES" in both of these, I should be setup to receive continuous events. Is this an oddity of the simulator or am I doing something wrong? NOTE: userInteractionEnabled is set to YES. NOTE2: I could setup a timer in beginTrackingWithTouch: withEvent: but that seems like more effort for something that should be simple.

  • Get notified when objective-c dom updates are ready initiated from webview

    - by Josh
    I am programmatically updating the DOM on a WebKit webview via DOMElement objects - for complex UI, there is usually a javascript component to any element that I add. This begs the need to be notified when the updates complete -- is there any such event? I know regular divs dont fire an onload or onready event, correct? The other assumption I had, which may be totally wrong, is that DOMElement updates aren't synchronous, so I can't do something like this and be confident it will meet with the label actually in the DOM: DOMElement *displayNameLabel = [document createElement:@"div"]; [displayNameLabel setAttribute:@"class" value:@"user-display-name"]; [displayNameLabel setTextContent:currentAvatar.avatarData.displayName]; [[document getElementById:@"user-card-content"] appendChild:displayNameLabel]; id win = [webView windowScriptObject]; [win evaluateWebScript:@"javascriptInstantiateLabel()"]; Is this true? I am using jquery within the body of the html already, so I don't mind subscribing to a particular classes set of events via "live." I thought I might be able to do something like: $(".some-class-to-be-added-later").live( "ready", function(){ // Instantiate some fantastic javascript here for .some-class }); but have experienced no joy so far. Is there any way on either side (objective-c since I don't programmatically firing javascript post load, or javascript) to be notified when the element is in the DOM? Thanks, Josh

  • Ajax Rich Internet Application framework for Linux + Firefox _AND_ iPhone consumption

    - by Maroloccio
    For a zero-budget (e.g. University) project we need to build a rich web UI for Firefox and iPhone clients. Firm requirement: all technologies to be free and open-source. Nice-to-have: all development to be done in Java/Eclipse. I generally like the Google's AppEngine + GWT combo but this project will require much more interactivity than what's in GWT 2.0. Something along the lines of: http://www.smartclient.com/smartgwt/showcase/. I know trusty plain ol' GWT won't cut it this time. Straight question: is there something that does the sort of thing that SmartGWT does and works really well on Safari/iPhone? I would say the mobile experience is even more important for this project than the desktop one. Optional question: perhaps this is not the best route to go at all? How could we otherwise render a rich UI with such capabilities and interactivity on both screen sizes? Windows, drag-and-drop, advanced tabs, dynamic grids... We don't need to support any other mobile devices. Yet. ;-)

  • Inside what the TexBox value is posted back? ViewState or post back data?

    - by burak ozdogan
    In one article I was reading on ViewState, I saw a sentence saying that I should not fall into a mistake to believe that the value of a TextBox is stored in ViewState; it is stored in PostBack data. From here what I understand is when I post back a web form, the input controls values are stored in HTTP Request body. Not in the Viewstate. But as far as I know ViewState values are stored in an hidden field called __VIEWSTATE anyway. Then does it mean that __VIEVSTATE value is not posted in HTTP POST Request body as a postback data? Sounds nonesense to me. In another words, basically if I say the ViewState mechanism for such scenerio works like this, am I seeing it right or skipping something: You enter a value on an empty TextBox and submit the page The value of text box is posted back inside POST HTTP Request body. Nothing inside __VIEWSTATE at this point from the TextBox On the server side, the TextBox is created with the default value on OnInit method of the page The TrackChange property of ViewState is set to true. The posted back data of TextBox is loaded. Because it is different than the TextBox defalut value(because the user entered something), the ViewState of this text box is marked as DIRTY. The new value of the textbox is written into __VIEWSTATE hidden field From now on __VIEWSTATE hiddenfeild contains the last given value of the TextBox The page is sent to the user's browser having the __VIEWSTATE hidden field. But this time containing the last value entered by user which will be ready to be rendered Thanks guys! burak ozdogan

  • Dragging a copy of all selected elements from a select box--possible?

    - by Sean
    I have a picklist web interface: a pair of select elements with a pair of buttons (a left-pointing arrow and a right-pointing arrow) between them. Users can move items between the two columns by, eg, selecting one of options in the left column and clicking on the right-pointing arrow. Now I have an enhancement request: someone wants to be able to drag-and-drop items between the two columns instead of clicking a button. The problem with my initial two-select-box setup is that as soon as I click one of the highlighted options to initiate a drag, all of the other selected options are deselected. Using jQuery, I've attached mousedown event handlers to both the select boxes and each individual option that just call preventDefault() on the event object, but this isn't sufficient. On Firefox 3 the clicked-on option loses focus immediately, but all other options are still deseleted, and on IE6 (which I regrettably still have to support) it makes no difference at all. So I thought I could maybe create a reasonable facsimile of a select box using list elements or divs or something. I can create something reasonable-looking that works on Firefox, but on IE6, if I shift-click on an element of my pseudo-select object (in order to select a range of options), IE selects all of the text between where I click and the last place I clicked. Again, I've attached preventDefault-ing mousedown, mouseup, and click handlers to all of the elements involved, but it doesn't help. I've even tried overlaying transparent divs over both my original select boxes and my pseudo-select objects, thinking to intercept mouse clicks and manage the selections manually, but I can't make it work on IE. If I use a select box, I can't prevent clicks from changing the selection, and if I use text that just looks like a select element, I can't prevent it from selecting a range of text on a shift-click. Is there some general solution, or am I just out of luck?

  • Switching AM/PM in ASP.NET AJAX MaskedEdit localization

    - by Greg
    The sample page for the MaskedEdit says "Tip: Type 'A' or 'P' to switch AM/PM". Are these keys hardcoded? Does the control automatically change itself for cultures that use 12-hour designators that don't start with A or P? Or is just broken for those? example: Arabic (Saudi Arabia) - AM: ? Arabic (Saudi Arabia) - PM: ? Chinese (Taiwan) - AM: ?? Chinese (Taiwan) - PM: ?? Greek (Greece) - AM: pµ Greek (Greece) - PM: µµ Korean (Korea) - AM: ?? Korean (Korea) - PM: ?? Albanian (Albania) - AM: PD Albanian (Albania) - PM: MD Persian (Iran) - AM: ?.? Persian (Iran) - PM: ?.? Vietnamese (Vietnam) - AM: SA Vietnamese (Vietnam) - PM: CH Afrikaans (South Africa) - PM: nm Punjabi (India) - AM: ????? Punjabi (India) - PM: ??? Syriac (Syria) - AM: ?.? Syriac (Syria) - PM: ?.? If this control doesn't handle this situation, does anyone know of a control that does?

  • CouchDB, HDFS, HBase or which is right for my situation?

    - by Lucas
    Hello all, This question is regarding data storage systems such as CouchDB, HDFS and HBase, specifically, which is right. I am looking at making a simple and customized Document Management System for my organization. Basically, we need the ability to store some Word Documents, PDFs and other similar files. I also want to store metadata about these files (e.g., Author, Dates, etc). Usage permissions would also be handy, but that can probably be built using meta-data. I would also need the ability to full-text index. The ability to version, while not required would be extremely useful. I would like the ability to simply add hardware to expand the resources of the system and the system must support Network Attached Storage over the CIFS or NFS protocol(s). I have read about CouchDB, HDFS and HBase. My preferred programming language is C# as all of my end-users will be running Windows machines and I will want to make both web and winforms client implementations. My question is which solution best fits my needs? Based on my research it appears that CouchDB (utilizing the CouchDB-Lounge and CouchDB-Lucene) perfectly fits my needs. However, I am worried that since I have worked with CouchDB that I might be overlooking something useful for my needs in HDFS or HBase or something similar due to a bias. Any and all opinions are welcome as I am looking for the community input as I really do not want to make the wrong choice at the start of my project. Please ask if you need more information. I thank you all for your time, input and assistance.

  • C# visually subclass datagridview control VS2005

    - by DRapp
    Maybe its something stupid, but I'm having a problem with a subclass of a DataGridView Control in VS2005 C#. I know I can subclass from almost anything by doing public class MyDataGridView : DataGridView {} no problem, and I put in some things / elements I want applicable globally. Now, I take this gridview and put into a custom user control that will contain other controls too. So I have something like created by the visual designer. I grab some buttons, label, and my derived "MyDataGridView" on it. public partial class MyCompoundDGVPlus : UserControl So, now, I can visually draw, move, change all sorts of settings as needed, no problem. Now, I want this "MyCompoundDGVPlus" class as the basis for other classes, of which I will manipulate settings specific, but want all to have the same look / feel, and otherwise similar flow, hence the derivations. I've even set the "modifiers" setting to public, so I SHOULD be able to modify any of the properties of the controls at any derived level. So, now, I create a new subclass of "MyFirstDetailedDGVPlus" derived from "MyCompoundDGVPlus". Ok visually, all the label, button, datagridview appear. However, now I want to specifically define the columns of the datagridview here in this class visually, but its locked. However, the LABEL on the form, I CAN get all the property settings.... What am I missing.
