  • custom *arbitrary* TemplateField definitions

    - by end-user
    I'm building a GridView on the fly, and I'd like to pre-define the TemplateFields to be included ondemand. So, what I'd like to do is have a declarative file that defines how the different templates look for a specific column. Like: <asp:TemplateField> <HeaderTemplate> this is a text column </HeaderTemplate> <ItemTemplate> data goes here </ItemTemplate> <EditItemTemplate> <asp:TextBox Text="databindhere" /> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> this is a bool column </HeaderTemplate> <ItemTemplate> if(true) "yes" else "no" </ItemTemplate> <EditItemTemplate> <asp:CheckBox Checked="databindme" /> </EditItemTemplate> </asp:TemplateField> So, if my query had a text and two bool fields, I could push the appropriate TemplateFields in the the Columns property as needed. (I hope I'm making sense here) So, how would I go about creating declarative files for the above definitions? And then, how would I reference those definitions programmatically?

  • Debugging scripts loaded with GroovyShell (in eclipse)

    - by MSh
    I am working with eclipse and groovy plug in. I am building a test harness to debug and test groovy scripts. The scripts are really simple but long, most of them just if/else/return. I figured out that I can call them using GroovyShell and Bindings to pass in the values. The problem is that, while I can call the script and get the results just fine, I CAN NOT step in there with the debugger. Breakpoints in those scripts are not active. Is there a way to debug the scripts? Maybe I should use something other than GroovyShell? I really don't want to modify the scripts by wrapping them into functions, and then calling those functions from my test classes. That's how I am using Binding and GroovyShell: def binding = new Binding(); binding.lineList = [list1]; binding.count = 5; def shell = new GroovyShell(binding); def result = shell.evaluate(new File("src/Rules/checkLimit.groovy"));

  • Custom PHP Framework Feedback

    - by Jascha
    I've been learning OOP programming for about a year and a half now and have developed a fairly standard framework to which I generally abide by. I'd love some feedback or input on how I might improve some functionality or if there are some things I'm overlooking. VIEW MODE 1) Essentially everything starts at the Index.php page. The first thing I do is require my "packages.php" file that is basically a config file that imports all of the classes and function lists I'll be using. 2) I have no direct communication between my index.php file and my classes, what I've done is "pretty them up" with my viewfunctions.php file which is essentially just a conduit to the classes so that in my html I can write <?php get_title('page'); ?> instead of <?php echo $pageClass->get_title('page'); ?> Plus, I can run a couple small booleans and what not in the view function script that can better tailor the output of the class. 3) Any information brought in via the database is started from it's corresponding class that has direct communication with the database class, the only class that is allowed direct to communicate with the database (allowed in the sense that I run all of my queries with custom class code). INPUT MODE 1) Any user input is sent to my userFunctions.php. 2) My security class is then instantiated where I send whatever user input that has been posted for verification and validation. 3) If the input passes my security check, I then pass it to my DB class for input into my Database. FEEDBACK I'm wondering if there are any glaringly obvious pitfalls to the general structure, or ways I can improve this. Thank you in advance for your input. I know there is real no "right" answer for this, but I imagine a couple up votes would be in order for some strong advice regarding building frameworks. -J

  • How to configure a NSPopupButton for displaying multiple values in a TableView?

    - by jekmac
    Hi there! I'm using two entities A and B with to-many-to-many relationship. Lets say I got an entity A with attribute aAttrib and a to-many relationship aRelat to another entity B with attribute bAttrib and a to-many relationship bRelat with entity A. Now I am building an interface with two tables one for entity A and another for entity B. The table for entity B has two columns one for bAttrib and one for the relationship aRelat. The aRelat-column should be a NSPopupButtonCell to display multiple aAttrib values. I'd like to set all the bindings in InterfaceBuilder in Table Column Bindings: -- I have two NSArrayController each for one entity: Object Controller Mode:Entity Array Controller Bindings: Parameters Managed Object Context bind to File's Owner -- One Table Cloumn with a PopUpButtonCell: TableCloumnBindings Content bind to Entity A with ControllerKey arrangedObjects; Content Values bind to Entity A with ModelKeyPath aAttrib Selected Object bind to Entity B with ModelKeyPath bRelat I know that this configuration doesn't allow multiple value setting. But I don't know how to do the right one. Getting the following message: HIToolbox: ignoring exception 'Unacceptable type of value for to-many relationship: property = "bRelat"; desired type = NSSet; given type = NSCFString; value = testValue.' that raised inside Carbon event dispatch... Does anyone have any idea?

  • Choosing approach for an IM client-server app

    - by John
    Update: totally re-wrote this to be more succint. I'm looking at a new application, one part of which will be very similar to standard IM clients, i.e text chat, ability to send attachments, maybe some real-time interaction like a multi-user whiteboard. It will be client-server, i.e all traffic goes through my central server. That means if I want to support cross-communication with other IM systems, I am still free to pick any protocol for my own client<--server communication - my server can use XMPP or whatever to talk to other systems. Clients are expected to include desktop apps, but probably also browser-based as well either through Flex/Silverlight or HTML/AJAX. I see 3 options for my own client-server communication layer: XMPP. The benefits are clients already exist as do open-source servers. However it requires the most up-front research/learning and also appears like it might raise legal issues due to GPL. Custom sockets. A server app makes connections with the clients, allowing any text/binary data to be sent very fast. However this approach requires building said server from scratch, and also makes a JS client tricky Servlets (or similar web server). Using tried and tested Java web-stack, clients send HTTP requests similar to AJAX-based websites. The benefit is the server is easy to write using well-established technologies, and easy to talk to. But what restrictions would this bring? Is it appropriate technology for real-time communication? Advice and suggests are welcome, especially what pros and cons surround using a web-server approach as compared to a socket-based approach.

  • I read 3 pages of a JQuery book and here's my reaction and question

    - by George
    My jQuery reaction to the language's flexible "selectors" is probably rooted in this experience: I once had managed a project where a developer constructed a web page that was used by users to provide very flexible search parameters for a search screen using dynamic sql string building based on the user's specified search parameter. The resulting queries were usually very complicated and involved joins to many tables. One of the options that the user had was to choose from one of 3 an options. Depending on the user's choice for this option, the resulting SQL would need to query a different set of database columns. For example, if choice option "A" were selected, the resulting database columns queried would be prefixed with "A_"; if option "B" were selected, he resulting database columns queried would be prefixed with "B_" and so on. The developer choice to write all the complete SQL assuming that the user selected, for example, option "A" and therefore first constructed SQLs of this type: SQL = "SELECT A_COL1, A_COL2, A_COL3 FROM TABLE ..." and then after constructing one of a million possible variations on the Query From Hell, did something like this: If UserOption = "B" then SQL = SQL.Replace("A_","B_") 'replace everywhere End if He insisted that this was the easiest was to code it, and while I understood that, I was concerned about maintenance of this code. You see, this worked for a while, but as the search options grew and the database columns evolved, the various "REPLACE small substring" with another small substring had unexpected consequences when applied to an evolving database and new search options. My feeling is that code should be written as much as possible such that you can add to it without fear of breaking what is already there. I feel a better approach, though a bit more work, would have been to write a function to return the appropriate target column based on a common set name and the user selected option. OK, so what does this have to do with jQuery selectors? Are the ultra flexible JQuery selectors kind of like perform a "replace all" on a SQL string? Handy as hell but potentially creating a maintenance nightmare?

  • PHP: Formatting multi-dimensional array as HTML?

    - by Industrial
    Hi everybody, I have tried to get my head around building a recursive function to handle formatting of a unknown depth multi-dimensional array to HTML and nested Divs. I thought that it should be a piece of cake, but no. Here's what I have come up with this far: function formatHtml($array) { $var = '<div>'; foreach ($array as $k => $v) { if (is_array($v['children']) && !empty($v['children'])) { formatHtml($v['children']); } else { $var .= $v['cid']; } } $var.= '</div>'; return $var; } And here's my array: Array ( [1] => Array ( [cid] => 1 [_parent] => [id] => 1 [name] => 'Root category' [children] => Array ( [2] => Array ( [cid] => 2 [_parent] => 1 [id] => 3 [name] => 'Child category' [children] => Array () ) ) ) ) Thanks a lot!

  • Link failure with either abnormal memory consumption or LNK1106 in Visual Studio 2005.

    - by Corvin
    Hello, I am trying to build a solution for windows XP in Visual Studio 2005. This solution contains 81 projects (static libs, exe's, dlls) and is being successfully used by our partners. I copied the solution bundle from their repository and tried setting it up on 3 similar machines of people in our group. I was successful on two machines and the solution failed to build on my machine. The build on my machine encountered two problems: During a simple build creation of the biggest static library (about 522Mb in debug mode) would fail with the message "13libd\ui1d.lib : fatal error LNK1106: invalid file or disk full: cannot seek to 0x20101879" Full solution rebuild creates this library, however when it comes to linking the library to main .exe file, devenv.exe spawns link.exe which consumes about 80Mb of physical memory and 250MB of virtual and spawns another link.exe, which does the same. This goes on until the system runs out of memory. On PCs of my colleagues where successful build could be performed, there is only one link.exe process which uses all the memory required for linking (about 500Mb physical). There is a plenty of hard drive space on my machine and the file system is NTFS. All three of our systems are similar - Core2Quad processors, 4Gb of RAM, Windows XP SP3. We are using Visual studio installed from the same source. I tried using a different RAM and CPU, using dedicated graphics adapter to eliminate possibility of video memory sharing influencing the build, putting solution files to different location, using different versions of VS 2005 (Professional, Standard and Team Suite), changing the amount of available virtual memory, running memtest86 and building the project from scratch (i.e. a clean bundle). I have read what MSDN says about LNK1106, none of the cases apply to me except for maybe "out of heap space", however I am not sure how I should fight this. The only idea that I have left is reinstalling the OS, however I am not sure that it would help and I am not sure that my situation wouldn't repeat itself on a different machine. Would anyone have any sort of advice for me? Thanks

  • Android app with library can't find the library.apk

    - by Dean Schulze
    I'm trying to get the FinchVideo example from the Programming Android book to work. It uses the FinchWelcome library. I've set up FinchWelcome as a Library and in the FinchVideo application I have checked the FinchWelcome library in Properties - Android. When I try to run FinchVideo in the emulator it complains that it cannot find FinchWelcome.apk (output below). I'm building for Android 4.0.3. While Googling for this problem I've found that a lot of people have this problem with Android apps that use libraries. No one seems to have found a solution that works consistently, though. None of the Android books I've seen even talk about how to download libraries. What is the proper way to handle libraries in Android applications? Is this a bug in the Eclipse ADT? Thanks. [FinchVideo] Installing FinchVideo.apk... [FinchVideo] Success! [FinchWelcome] Could not find FinchWelcome.apk!

  • What type of data store should I use for my ios app?

    - by mwiederrecht
    I am pretty new to ios and using servers so forgive me. I am building an ios app for research. I need to monitor things that the user does and then push it up to a server for analysis (yes, with user and IRB permission). On the client's side I need to keep quite a bit of data that won't really change except in the case of pulling an updated version from the server, and then a minimal amount of user-specific data. Most of the data I will collect needs to be pushed to a server for analysis and then can be deleted from the client side. I am struggling to figure out what kind of data store I need to use, especially since I am not quite sure how the pushing and pulling from the server process works yet. Does it make sense to use Core Data? XML? SQLite? I like the Core Data idea, but I am not sure what kind of problems I will run into when I need to send large amounts of data to it and from it from the server. I imagine I might need to send data in a different form than it is probably stored in on either end - so what kind of overhead am I likely to run into in the process of converting that data? Is there a good format to save stuff in that would work well for me on both ends AND for sending the data? As you can probably tell, I could use some advice. Thanks!

  • rendering a TextView in a Bitmap for an android widget

    - by foke
    I'm building a widget which displays some text. By widget I mean the kind which lies on the desktop. The problem is that I want to change text's font at runtime. There is several textview I would like, at runtime, to set the first as bold, the second blue and italic for example, etc. I came up with this : TextView tv = new TextView(context); tv.setText(stringToDisplay); tv.setTextColor(0xa00050ff); // example tv.setTextSize(30); // example Bitmap b = loadBitmapFromView(tv); updateViews.setImageViewBitmap(R.id.id_of_the_imageview, b); with private static Bitmap loadBitmapFromView(View v) { Bitmap b = Bitmap.createBitmap(v.getLayoutParams().width, v.getLayoutParams().height, Bitmap.Config.ARGB_8888); Canvas c = new Canvas(b); v.layout(0, 0, v.getLayoutParams().width, v.getLayoutParams().height); v.draw(c); return b; } but it wont work (NullPointerException on first line of loadBitmap), until I replace v.getLayoutParams().width, v.getLayoutParams().height by fixed sizes like 250, 50 Bitmap b = Bitmap.createBitmap(250, 50, Bitmap.Config.ARGB_8888); // ... v.layout(0, 0, 250, 50); But that's not a good solution ... so I tried this : LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View row = li.inflate(R.layout.widget_text, null); TextView tv = (TextView) row.findViewById(R.id.id_of_the_textview); widget_text being a layout similar to the displayed one but with TextViews instead of ImageViews, in the hope to get some size information out of it .. but it's not working and I get this exception : 01-02 17:35:06.001: ERROR/AndroidRuntime(11025): Caused by: java.lang.IllegalArgumentException: width and height must be > 0 on the call to Bitmap.createBitmap() so, someone could point me in the right direction?

  • Database (MySQL) structuring: pros and cons of multiple tables

    - by Gideon
    I am collecting data and storing it MySQL, for: 75 variables 55 countries Each year I have, at this stage since I am building this tool created a single table, of variables / countries (storing 1 year worth of data). Next year (and for several years after that) a new set of data will be input for each country. There are therefore 3 variables in controlling data returned to a user reviewing all collected data. The general form of any query would be: Show me these specifics variables, for these specific countries, for these specific years. (Show me average age and weight, for USA and Canada, for 2012 and 2009, for example) My question is, it seems that I have two options for arranging this data: -Multiple tables where I create a table of country / variable for each year data is collected - Single table and simply add a column (field) for the year that data relates to. As far as I can tell I could make these database calls with either sructure, but is one more powerful / efficient / quicker, and why? Thanks for your consideration. It's a PDO / PHP interface if that is relevent.

  • AngularJS: Using Shared Service(with $resource) to share data between controllers, but how to define callback functions?

    - by shaunlim
    Note: I also posted this question on the AngularJS mailing list here: https://groups.google.com/forum/#!topic/angular/UC8_pZsdn2U Hi All, I'm building my first AngularJS app and am not very familiar with Javascript to begin with so any guidance will be much appreciated :) My App has two controllers, ClientController and CountryController. In CountryController, I'm retrieving a list of countries from a CountryService that uses the $resource object. This works fine, but I want to be able to share the list of countries with the ClientController. After some research, I read that I should use the CountryService to store the data and inject that service into both controllers. This was the code I had before: CountryService: services.factory('CountryService', function($resource) { return $resource('http://localhost:port/restwrapper/client.json', {port: ':8080'}); }); CountryController: //Get list of countries //inherently async query using deferred promise $scope.countries = CountryService.query(function(result){ //preselected first entry as default $scope.selected.country = $scope.countries[0]; }); And after my changes, they look like this: CountryService: services.factory('CountryService', function($resource) { var countryService = {}; var data; var resource = $resource('http://localhost:port/restwrapper/country.json', {port: ':8080'}); var countries = function() { data = resource.query(); return data; } return { getCountries: function() { if(data) { console.log("returning cached data"); return data; } else { console.log("getting countries from server"); return countries(); } } }; }); CountryController: $scope.countries = CountryService.getCountries(function(result){ console.log("i need a callback function here..."); }); The problem is that I used to be able to use the callback function in $resource.query() to preselect a default selection, but now that I've moved the query() call to within my CountryService, I seemed to have lost what. What's the best way to go about solving this problem? Thanks for your help, Shaun

  • Retrieving my own data via FaceBook API

    - by goggin13
    I am building a website for a comedy group which uses Facebook as one of their marketing platforms; one of the requirements for the new site is to display all of their Facebook events on a calendar. Currently, I am just trying to put together a Python script which can pull some data from my own Facebook account, like a list of all my friends. I presume once I can accomplish this I can move to pulling more complicated data out of my clients account (since they have given me access to their account). I have looked at many of the posts here, and also went through the Facebook API documentation, including Facebook Connect, but am really beating my head against the wall. Everything I have read seems like overkill, as it involves setting up a good deal of infrastructure to allow my app to set up connections to any arbitrary user's account (who authorizes me). Shouldn't it be much simpler, given I only ever need to access 1 account? I cannot find a way to retrieve data without having to display the Facebook login window. I have a script which will retrieve all my friends, but it includes a redirect where I have to physically log myself in to Facebook. Would appreciate any advice or links, I just feel like I must be missing something simple. Thank you!

  • AIX 6.1 unable to build apache module

    - by user3715581
    In Aix 6.1/ Apache version 2.2.8 packaged as part of IBM WebSphere. We should have had mod_dumpio for this version but for some reasons IBM did not include it. So we are trying to build this module(in few many ways) but none of them worked. 1) Using apxs:- Failed with the "xlc_r" not found as compile option for libtool. So based on an article online, we changed to "gcc" and we have to remove -qmaxmem and -qHALT to make it work. Result we see a .lo created but LoadModule fails(unable to find .loader section). 2) Using gcc:- Command "gcc -fpic -DSHARED_MODULE -I -c mod_dumpio.c" After running this command, we can see .o file created and then we tried to execute "ld -Bshareable -o mod_dumpio.so mod_dumpio.o" whereas AIX complaining about -Bshareable so we tried using this command "gcc -shared -I -o mod_dumpio.so mod_dumpio.o" whereas the error was "libgcc_s" not found. Then we added -static-libgcc to the above command and it was not resolving .h file functions (Unknown symbols). From IBM AIX site, libgcc_s costs around $2k. We think our second approach may work but we dont know how to instruct gcc to look for .h files while building .so from .o. Any help is appreciated.

  • LINQ to SQL: NOTing a prebuilt expression

    - by ck
    I'm building a library of functions for one of my core L2S classes, all of which return a bool to allow checking for certain situations. Example: Expression<Func<Account, bool>> IsSomethingX = a => a.AccountSupplementary != null && a.AccountSupplementary.SomethingXFlag != null && a.AccountSupplementary.SomethingXFlag.Value; Now to query where this is not true, I CAN'T do this: var myAccounts= context.Accounts .Where(!IsSomethingX); // does not compile However, using the syntax from the PredicateBuilder class, I've come up with this: public static IQueryable<T> WhereNot<T>(this IQueryable<T> items, Expression<Func<T, bool>> expr1) { var invokedExpr = Expression.Invoke(expr1, expr1.Parameters.Cast<Expression>()); return items.Where(Expression.Lambda<Func<T, bool>> (Expression.Not(invokedExpr), expr1.Parameters)); } var myAccounts= context.Accounts .WhereNot(IsSomethingX); // does compile which actually produces the correct SQL. Does this look like a good solution, and is there anything I need to be aware of that might cause me problems in future?

  • Risky Business with LINQ to SQL and OR Designer?

    - by Toadmyster
    I have two tables with a one to many relationship in SQL 2008. The first table (BBD) PK | BBDataID | int       | Floor_Qty | tinyint       | Construct_Year | char(4)       | etc, etc describes the data common to all buildings and the second (BBDCerts) PK | BBDCertsID | int       | BBDataID | int       | Certification_Type | varchar(20)       | etc, etc is a collection of certifications for a particular building. Thus, the primary key in BBD (BBDataID) is mapped to the corresponding field in BBDCerts via an FK relationship, but BBDCertsID is the second table's primary key and BBDataID is not because it will not be unique. My problem is that I want to be able to use the OR generated data context to get at the list of certs when I access a particular record in the BBD table. For instance: Dim vals = (From q in db.BBD Where q.BBDataID = x Select q.Floor_Qty, q.Construct_Year, q.BBDCerts).SingleOrDefault and later be able to access a particular certification like this: vals.BBDCerts.Certification_Type.First Now, the automatic associations created when the SQL tables are dropped on the design surface don't generate the EntityRef associations that are needed to access the other table using the dot notation. So, I have to use the OR designer to make the BBDCerts BBDataID a primary key (this doesn't affect the actual database), and then manually change the association properties to the appropriate OneToMany settings. There might be a better way to approach this solution but my question is, is the way I've done it safe? I've done a barrage of tests and the correct cert is referenced or updated every time. Frankly, the whole thing makes me nervous.

  • Concatenate an each loop inside another

    - by Lothar
    I want to to concatenate the results of a jquery each loop inside of another but am not getting the results I expect. $.each(data, function () { counter++; var i = 0; var singlebar; var that = this; tableRow = '<tr>' + '<td>' + this.foo + '</td>' + $.each(this.bar, function(){ singlebar = '<td>' + that.bar[i].baz + '</td>'; tableRow + singlebar; }); '</tr>'; return tableRow; }); The portion inside the nested each does not get added to the string that is returned. I can console.log(singlebar) and get the expected results in the console but I cannot concatenate those results inside the primary each loop. I have also tried: $.each(this.bar, function(){ tableRow += '<td>' + that.bar[i].baz + '</td>'; }); Which also does not add the desired content. How do I iterate over this nested data and add it in the midst of the table that the primary each statement is building?

    Hi I'm having a bit of an issue with a asp.net repeater I'm building a categories carousel with the dynamic categories being output by a repeater. Each item is a LinkButton control that passes an argument of the category id to the onItemClick handler. a page variable is set by this handler to track what the selected category id is.... public String SelectedID { get { object o = this.ViewState["_SelectedID"]; if (o == null) return "-1"; else return (String)o; } set { this.ViewState["_SelectedID"] = value; } } problem is that i cant seem to read this value while iterating through the repeater as follows... <asp:Repeater ID="categoriesCarouselRepeater" runat="server" onitemcommand="categoriesCarouselRepeater_ItemCommand"> <ItemTemplate> <%#Convert.ToInt32(Eval("CategoryID")) == Convert.ToInt32(SelectedID) ?

  • Checking if user owns file before deleting it

    - by Martin Hoe
    I'm building an API for my site that allows users to delete the files they upload. Obviously, I want to check if the user owns that file before they delete it through the API. I have a files table and a users table, here's the schema: f_id, s_id, u_id, name, size, uploaded u_id, username, password, email, activated, activation_code u_id is a foreign key. The u_id field in the files table points to the u_id in the users table. Given the users username, I want to find the users u_id, and then check if they own the file through the file ID (f_id). I wrote this SQL: $sql = 'SELECT u.username FROM `users` u JOIN `files` f ON u.u_id = f.u_id WHERE f_id = ? AND u.u_id = ? LIMIT 1'; I'm assuming that'd work if I was given the users u_id in the API request, but alas I'm given only their username. How can I modify that SQL to find their user ID and use that? Thanks. Edit: Alright I've got this query but it's always returning an empty result set even though both the file ID and username exist. SELECT u.username FROM `users` u JOIN `files` f ON u.u_id = f.u_id WHERE f.f_id = ? AND u.username = ? LIMIT 1

  • Memory not being returned after function python call

The grammar g is just a dictionary from strings to heaps, e.g.: g['et'] [(1.05, 'and'), (6.92, ', and'), (9.95, 'and ,'), (11.17, 'and to')] EDIT: If you want to run the code, try the sentence "Cela est difficile" with the following grammar: >>> g['cela'] [(8.28, 'this'), (11.21, 'it'), (11.57, 'that'), (15.26, 'this ,')] >>> g['est'] [(2.69, 'is'), (10.21, 'is ,'), (11.15, 'has'), (11.28, ', is')] >>> g['difficile'] [(2.01, 'difficult'), (10.08, 'hard'), (10.19, 'difficult ,'), (10.57, 'a difficult')]

  • SQL - table alias scope.

    - by Support - multilanguage SO
    I've just learned ( yesterday ) to use "exists" instead of "in". BAD select * from table where nameid in ( select nameid from othertable where otherdesc = 'SomeDesc' ) GOOD select * from table t where exists ( select nameid from othertable o where t.nameid = o.nameid and otherdesc = 'SomeDesc' ) And I have some questions about this: 1) The explanation as I understood was: "The reason why this is better is because only the matching values will be returned instead of building a massive list of possible results". Does that mean that while the first subquery might return 900 results the second will return only 1 ( yes or no )? 2) In the past I have had the RDBMS complainin: "only the first 1000 rows might be retrieved", this second approach would solve that problem? 3) What is the scope of the alias in the second subquery?... does the alias only lives in the parenthesis? for example select * from table t where exists ( select nameid from othertable o where t.nameid = o.nameid and otherdesc = 'SomeDesc' ) AND select nameid from othertable o where t.nameid = o.nameid and otherdesc = 'SomeOtherDesc' ) That is, if I use the same alias ( o for table othertable ) In the second "exist" will it present any problem with the first exists? or are they totally independent? Is this something Oracle only related or it is valid for most RDBMS? Thanks a lot

  • including pre-built java classes into an android project

    - by moonlightcheese
    i'm trying to include a maven java project into my android project. the maven project is the greader-unofficial project which allows developers access to google reader accounts, and handles all of the http transactions and URI/URL building, making grabbing feeds and items from google reader transparent to the developer. the project is available here: http://code.google.com/p/greader-unofficial/ the code is originally written for the standard jdk and uses classes from java.net that are not a part of the standard Android SDK. i actually tried to manually resolve all dependencies and ran into a problem when i got as far as including com.sun.syndication pieces required by the class be.lechtitseb.google.reader.api.util.AtomUtil.java... some of the classes in java.net that are in the standard jdk (i'm using 1.6) are not in the Android SDK. in addition, resolving all of these dependencies manually is just ridiculous when i'm compiling a maven project that should be pretty simple. however, i can use maven to compile the sources with no issue. how can i include this maven project, which is dependent on the complete jdk, into my android project in such a way that it will compile so that i can access the GoogleReader class from my android project? and for the record, i don't have the expertise to rewrite this entire api to work with the standard Android SDK.

  • MemoryStream instance timing help

    - by rod
    Hi All, Is it ok to instance a MemoryStream at the top of my method, do a bunch of stuff to it, and then use it? For instance: public static byte[] TestCode() { MemoryStream m = new MemoryStream(); ... ... whole bunch of stuff in between ... ... //finally using(m) { return m.ToArray(); } } Updated code public static byte[] GetSamplePDF() { using (MemoryStream m = new MemoryStream()) { Document document = new Document(); PdfWriter.GetInstance(document, m); document.Open(); PopulateTheDocument(document); document.Close(); return m.ToArray(); } } private static void PopulateTheDocument(Document document) { Table aTable = new Table(2, 2); aTable.AddCell("0.0"); aTable.AddCell("0.1"); aTable.AddCell("1.0"); aTable.AddCell("1.1"); document.Add(aTable); for (int i = 0; i < 20; i++) { document.Add(new Phrase("Hello World, Hello Sun, Hello Moon, Hello Stars, Hello Sea, Hello Land, Hello People. ")); } } My point was to try to reuse building the byte code. In other words, build up any kind of document and then send it to TestCode() method.

  • Gtk: How can I get a part of a file in a textview with scrollbars relating to the full file

    - by badgerman1
    I'm trying to make a very large file editor (where the editor only stores a part of the buffer in memory at a time), but I'm stuck while building my textview object. Basically- I know that I have to be able to update the text view buffer dynamically, and I don't know hot to get the scrollbars to relate to the full file while the textview contains only a small buffer of the file. I've played with Gtk.Adjustment on a Gtk.ScrolledWindow and ScrollBars, but though I can extend the range of the scrollbars, they still apply to the range of the buffer and not the filesize (which I try to set via Gtk.Adjustment parameters) when I load into textview. I need to have a widget that "knows" that it is looking at a part of a file, and can load/unload buffers as necessary to view different parts of the file. So far, I believe I'll respond to the "change_view" to calculate when I'm off, or about to be off the current buffer and need to load the next, but I don't know how to get the scrollbars to have the top relate to the beginning of the file, and the bottom relate to the end of the file, rather than to the loaded buffer in textview. Any help would be greatly appreciated, thanks!
