• How can I create a WebBrowser control (ActiveX / IWebBrowser2) without a UI?

  - by wangminhere

  I cannot figure out how to use the WebBrowser control without having it create a window in the taskbar. I am using the IWebBrowser2 ActiveX control directly because I need to use some of the advanced features like blocking downloading JAVA/ActiveX/images etc. That apparently is not available in the WPF or winforms WebBrowser wrappers (but these wrappers do have the ability to create the control with no UI) Here is my code for creating the control: Type webbrowsertype = Type.GetTypeFromCLSID(Iid_Clsids.CLSID_WebBrowser, true); m_WBWebBrowser2 = (IWebBrowser2)System.Activator.CreateInstance(webbrowsertype); m_WBWebBrowser2.Visible = false; m_WBOleObject = (IOleObject)m_WBWebBrowser2; int iret = m_WBOleObject.SetClientSite(this); iret = m_WBOleObject.SetHostNames("me", string.Empty); tagRECT rect = new tagRECT(0, 0, 0, 0); tagMSG nullMsg = new tagMSG(); m_WBOleInPlaceObject = (IOleInPlaceObject)m_WBWebBrowser2; //INPLACEACTIVATE the WB iret = m_WBOleObject.DoVerb((int)OLEDOVERB.OLEIVERB_INPLACEACTIVATE, ref nullMsg, this, 0, IntPtr.Zero, ref rect); IConnectionPointContainer cpCont = (IConnectionPointContainer)m_WBWebBrowser2; Guid guid = typeof(DWebBrowserEvents2).GUID; IConnectionPoint m_WBConnectionPoint = null; cpCont.FindConnectionPoint(ref guid, out m_WBConnectionPoint); m_WBConnectionPoint.Advise(this, out m_dwCookie); This code works perfectly but it shows a window in the taskbar. If i omit the DoVerb(OLEDOVERB.OLEIVERB_INPLACEACTIVATE) call, then Navigating to a webpage is not working properly. Navigate() will not download everything on the page and it never fires the DocumentComplete event. If I add a DoVerb(OLEIVERB_HIDE) then I get the same behavior as if I omitted the DoVerb(OLEDOVERB.OLEIVERB_INPLACEACTIVATE) call. This seems like a pretty basic question but I couldn't find any examples anywhere.

• How can I include a .eps figure within a Tikz simple flow chart?

  - by Jan

  Hi, I would like to create a simple flow chart in latex with the TikZ package similar to the following example http://www.texample.net/tikz/examples/simple-flow-chart/ However I would like to include figures (a time series plot created in R, as eps or something else) within the flowchart (e.g. for example within a {block}? \documentclass{article} \usepackage[latin1]{inputenc} \usepackage{tikz} \usetikzlibrary{shapes,arrows} \begin{document} \pagestyle{empty} % Define block styles \tikzstyle{decision} = [diamond, draw, fill=blue!20, text width=4.5em, text badly centered, node distance=3cm, inner sep=0pt] \tikzstyle{block} = [rectangle, draw, fill=blue!20, text width=5em, text centered, rounded corners, minimum height=4em] \tikzstyle{line} = [draw, -latex'] \tikzstyle{cloud} = [draw, ellipse,fill=red!20, node distance=3cm, minimum height=2em] \begin{tikzpicture}[node distance = 2cm, auto] % Place nodes \node [block] (init) {initialize model}; \node [cloud, left of=init] (expert) {expert}; \node [cloud, right of=init] (system) {system}; \node [block, below of=init] (identify) {identify candidate models}; \node [block, below of=identify] (evaluate) {evaluate candidate models}; \node [block, left of=evaluate, node distance=3cm] (update) {update model}; \node [decision, below of=evaluate] (decide) {is best candidate better?}; \node [block, below of=decide, node distance=3cm] (stop) {stop}; % Draw edges \path [line] (init) -- (identify); \path [line] (identify) -- (evaluate); \path [line] (evaluate) -- (decide); \path [line] (decide) -| node [near start] {yes} (update); \path [line] (update) |- (identify); \path [line] (decide) -- node {no}(stop); \path [line,dashed] (expert) -- (init); \path [line,dashed] (system) -- (init); \path [line,dashed] (system) |- (evaluate); \end{tikzpicture} \end{document} Thanks, Jan

• Getting a users Facebook profile url

  - by Greg Pabst

  I am creating a registry site so similar people can find each other easily. I don't want to use Facebook Connect as the primary log in method or use Facebook to store their information. I'll be creating a database on my end to store that info. For security reasons I won't be displaying the users address, phone number or email address so I wanted to provide the next best way for people to connect with each other, this is where Facebook comes in. Normally I would just ask them to type their Facebook URL in a text box but I don't think most people know what their url is which is why I think I need to use Facebook Connect. So here is my idea..when the users signs up there is a check box that when checked signifies they are allowing people to find them on Facebook. I assume once they click the register button that a Facebook Connect popup will show up asking for permission to access their Facebook account. When they "allow" it, then I can get their profile url. All I need is their Facebook profile url, I don't want any other Facebook features or information. Is Facebook Connect the best thing to use for this scenario? Is there an easier way? Several months ago on the Facebook Connect site their used to be examples of doing this, but all the documentation has been rearranged and changed and I can't seem to find the information. Any help you can provide would be great!

• Computing complex math equations in python

  - by dassouki

  Are there any libraries or techniques that simplify computing equations ? Take the following two examples: F = B * { [ a * b * sumOf (A / B ''' for all i ''' ) ] / [ sumOf(c * d * j) ] } where: F = cost from i to j B, a, b, c, d, j are all vectors in the format [ [zone_i, zone_j, cost_of_i_to_j], [..]] This should produce a vector F [ [1,2, F_1_2], ..., [i,j, F_i_j] ] T_ij = [ P_i * A_i * F_i_j] / [ SumOf [ Aj * F_i_j ] // j = 1 to j = n ] where: n is the number of zones T = vector [ [1, 2, A_1_2, P_1_2], ..., [i, j, A_i_j, P_i_j] ] F = vector [1, 2, F_1_2], ..., [i, j, F_i_j] so P_i would be the sum of all P_i_j for all j and Aj would be sum of all P_j for all i I'm not sure what I'm looking for, but perhaps a parser for these equations or methods to deal with multiple multiplications and products between vectors? To calculate some of the factors, for example A_j, this is what i use from collections import defaultdict A_j_dict = defaultdict(float) for A_item in TG: A_j_dict[A_item[1]] += A_item[3] Although this works fine, I really feel that it is a brute force / hacking method and unmaintainable in the case we want to add more variables or parameters. Are there any math equation parsers you'd recommend? Side Note: These equations are used to model travel. Currently I use excel to solve a lot of these equations; and I find that process to be daunting. I'd rather move to python where it pulls the data directly from our database (postgres) and outputs the results into the database. All that is figured out. I'm just struggling with evaluating the equations themselves. Thanks :)

• How to float a <div> echoed in the footer over a <div> located elsewhere (PHP/jQuery/HTML/CSS)

  - by PlasmaFlux

  Hello All! I'm embarking on a major project, but am stuck on a tiny issue at the very start. I'll try to be as concise as possible. I have a PHP script that will be echoing into the footer of the page (the last stuff before a bunch of s containing visible buttons and s containing hidden dialog boxes. The plan is to have the buttons float in the upper-right corner of corresponding s in the main content area of the page. i.e. - button-1 echoed into the footer will float in the corner of content-box-1, and will be tied to the hidden 'dialog-1'. I'll be using jQuery and jQuery UI Dialog throughout the page(s). I'm not sure if that's particularly relevant to this question, but thought it worth mentioning just in case. So my question, put simply, is how do I echo a Button 1 into the footer with PHP, but have it float in the upper-right corner (with maybe 5px margin) of Content 1 is full of content? A picture says a thousand words: As shown above, I want the little blue gear button things in the corner of content pieces, locked and loaded with hidden s containing dialog boxes. Again, the catch is that all buttons and hidden divs will be the very last items echoed into the page footer. I've found plenty of info on how to float divs on top of divs, but all the examples I saw showed the s in close proximity to each other in the page source; not with a hundred lines of source code between the two s I'm not sure if the solution is pure CSS, pure jQuery/jQueryUI or a combination of the two. Any advice will be much appreciated. Thanks!

• Hadoop Map/Reduce - simple use example to do the following...

  - by alexeypro

  I have MySQL database, where I store the following BLOB (which contains JSON object) and ID (for this JSON object). JSON object contains a lot of different information. Say, "city:Los Angeles" and "state:California". There are about 500k of such records for now, but they are growing. And each JSON object is quite big. My goal is to do searches (real-time) in MySQL database. Say, I want to search for all JSON objects which have "state" to "California" and "city" to "San Francisco". I want to utilize Hadoop for the task. My idea is that there will be "job", which takes chunks of, say, 100 records (rows) from MySQL, verifies them according to the given search criteria, returns those (ID's) which qualify. Pros/cons? I understand that one might think that I should utilize simple SQL power for that, but the thing is that JSON object structure is pretty "heavy", if I put it as SQL schemas, there will be at least 3-5 tables joins, which (I tried, really) creates quite a headache, and building all the right indexes eats RAM faster than I one can think. ;-) And even then, every SQL query has to be analyzed to be utilizing the indexes, otherwise with full scan it literally is a pain. And with such structure we have the only way "up" is just with vertical scaling. But I am not sure it's the best option for me, as I see how JSON objects will grow (the data structure), and I see that the number of them will grow too. :-) Help? Can somebody point me to simple examples of how this can be done? Does it make sense at all? Am I missing something important? Thank you.

• unable to implement HTTP Tunneling correctly in order to enable Java rmi calls over internet(and und

  - by Lokesh Kumar

  in my previous question :-How to Setup RMI Server under(NAT/ISP) Now,i m able to start my RMI server by Installing apache Tomcat 6.0 server. i have also installed servlet programs into apache Tomcat server in order to enable HTTP tunneling. my servlet codes:- (1) [SimplifiedServletHandler.java][2] (2) [ServletForwardCommand.java][3] these servlets resides inside :- C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\examples\WEB-INF\classes\ one more thing that i hv added to my CalcultorClient.java program:- try { RMISocketFactory. setSocketFactory(new sun.rmi.transport.proxy .RMIHttpToCGISocketFactory( )); }catch (IOException ignored) { System.out.println("Error :- ignored.getMessage()"); } But,when i try to make client connect with server(under ISP/NAT) i get the following Exception :- RemoteException java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is: java.io.IOException: HTTP request failed i don't know the correct reason behind this Exception.. but,i think that i haven't installed or invoke my servlet programs properly on server side. so,can anybody tell me the correct reason behind this error/Exception????? and if u think that it is servlet problem then tell me the correct procedure to run my serlvet program inside tomcat server.

• What's your most controversial programming opinion?

  - by Jon Skeet

  This is definitely subjective, but I'd like to try to avoid it becoming argumentative. I think it could be an interesting question if people treat it appropriately. The idea for this question came from the comment thread from my answer to the "What are five things you hate about your favorite language?" question. I contended that classes in C# should be sealed by default - I won't put my reasoning in the question, but I might write a fuller explanation as an answer to this question. I was surprised at the heat of the discussion in the comments (25 comments currently). So, what contentious opinions do you hold? I'd rather avoid the kind of thing which ends up being pretty religious with relatively little basis (e.g. brace placing) but examples might include things like "unit testing isn't actually terribly helpful" or "public fields are okay really". The important thing (to me, anyway) is that you've got reasons behind your opinions. Please present your opinion and reasoning - I would encourage people to vote for opinions which are well-argued and interesting, whether or not you happen to agree with them.

• Rolling Back a Transaction with MySQL Connector in VB.net

  - by Jonathan

  Hey all- I have one multi-row INSERT statement (300 or so sets of values) that I would like to commit to the MySQL database in an all-or-nothing fashion. insert into table VALUES (1, 2, 3), (4, 5, 6), (7, 8, 9); In some cases, a set of values in the command will not meet the criteria of the table (duplicate key, for example). When that happens I do not want any of the previous sets added to the database. I've implemented this with the following code, however, my rollback command doesn't appear to be making a difference. I've used this documentation: http://dev.mysql.com/doc/refman/5.0/es/connector-net-examples-mysqltransaction.html Dim transaction As MySqlTransaction = sqlConnection.BeginTransaction() sqlCommand = New MySqlCommand(insertStr, sqlConnection, transaction) Try sqlCommand.ExecuteNonQuery() Catch ex As Exception writeToLog("EXCEPTION: " & ex.Message & vbNewLine) writeToLog("Could not execute " & sqlCmd & vbNewLine) Try transaction.Rollback() writeToLog("All statements were rolled back." & vbNewLine) Return False Catch rollbackEx As Exception writeToLog("EXCEPTION: " & rollbackEx.Message & vbNewLine) writeToLog("All statements were not rolled back." & vbNewLine) Return False End Try End Try transaction.commit() I get the DUPLICATE KEY exception thrown, no Rollback Exception thrown, and every set of values up to duplicate key committed to the database. What am I doing wrong? Thanks- Jonathan

• Generating All Permutations of Character Combinations when # of arrays and length of each array are

  - by Jay

  Hi everyone, I'm not sure how to ask my question in a succinct way, so I'll start with examples and expand from there. I am working with VBA, but I think this problem is non language specific and would only require a bright mind that can provide a pseudo code framework. Thanks in advance for the help! Example: I have 3 Character Arrays Like So: Arr_1 = [X,Y,Z] Arr_2 = [A,B] Arr_3 = [1,2,3,4] I would like to generate ALL possible permutations of the character arrays like so: XA1 XA2 XA3 XA4 XB1 XB2 XB3 XB4 YA1 YA2 . . . ZB3 ZB4 This can be easily solved using 3 while loops or for loops. My question is how do I solve for this if the # of arrays is unknown and the length of each array is unknown? So as an example with 4 character arrays: Arr_1 = [X,Y,Z] Arr_2 = [A,B] Arr_3 = [1,2,3,4] Arr_4 = [a,b] I would need to generate: XA1a XA1b XA2a XA2b XA3a XA3b XA4a XA4b . . . ZB4a ZB4b So the Generalized Example would be: Arr_1 = [...] Arr_2 = [...] Arr_3 = [...] . . . Arr_x = [...] Is there a way to structure a function that will generate an unknown number of loops and loop through the length of each array to generate the permutations? Or maybe there's a better way to think about the problem? Thanks Everyone!

• ArrayAdapter and android:textFilterEnabled

  - by TiGer

  Hi there, I have created a layout which includes a ListView... The data shown within this ListView isn't too complicated, it's mostly an Array which is passed when the extended Activity is started... The rows themselves exist out of an icon and a text, thus an ImageView and a TextView... To fill up the ListView I use an ArrayAdapter simply because an Array is passed containing all the text-items that should be shown.. Now I'd like to actually be able to filter those, thus I found the android:textFilterEnabled paramater to add on the ListView xml declaration... Now a search field is shown nicely but when I enter some letters it won't filter but it will simply delete the whole list... I found out that that's because the textfilter has no idea what it should filter... So now my question is : I know I need to tell the textfilter what it should filter, I also still have my array filled with the text that should get filtered so how do i couple those two ??? I have seen examples extending a CursorAdapter, but again, I don't have a Cursor, I don't want to do calls to a DB I want to re-utilize my Array with data and obviously the ArrayAdapter itself so that the data will be represented decently on screen (i.e with my ImageView and TextView layout)... Thanks in advance for any help/pointers/tips/code...

• F# Async problem.

• How to gray out HTML form inputs?

  - by typoknig

  What is the best way to gray out text inputs on an HTML form? I need the inputs to be grayed out when a user checks a check box. Do I have to use JavaScript for this (not very familiar with JScript) or can I use PHP (which I am more familiar with)? EDIT: After some reading I have got a little bit of code, but it is giving me problems. For some reason I cannot get my script to work based on the state of the form input (enabled or disabled) or the state of my checkbox (checked or unchecked), but my script works fine when I base it on the values of the form inputs. I have written my code exactly like several examples online (mainly this one) but to no avail. None of the stuff that is commented out will work. What am I doing wrong here? <label>Mailing address same as residental address</label> <input name="checkbox" onclick="disable_enable() "type="checkbox" style="width:15px"/><br/><br/> <script type="text/javascript"> function disable_enable(){ if (document.form.mail_street_address.value==1) document.form.mail_street_address.value=0; //document.form.mail_street_address.disabled=true; //document.form.mail_city.disabled=true; //document.form.mail_state.disabled=true; //document.form.mail_zip.disabled=true; else document.form.mail_street_address.value=1; //document.form.mail_street.disabled=false; //document.form.mail_city.disabled=false; //document.form.mail_state.disabled=false; //document.form.mail_zip.disabled=false; } </script>

• DDD and MVC: Difference between 'Model' and 'Entity'

  - by Nathan Loding

  I'm seriously confused about the concept of the 'Model' in MVC. Most frameworks that exist today put the Model between the Controller and the database, and the Model almost acts like a database abstraction layer. The concept of 'Fat Model Skinny Controller' is lost as the Controller starts doing more and more logic. In DDD, there is also the concept of a Domain Entity, which has a unique identity to it. As I understand it, a user is a good example of an Entity (unique userid, for instance). The Entity has a life-cycle -- it's values can change throughout the course of the action -- and then it's saved or discarded. The Entity I describe above is what I thought Model was supposed to be in MVC? How off-base am I? To clutter things more, you throw in other patterns, such as the Repository pattern (maybe putting a Service in there). It's pretty clear how the Repository would interact with an Entity -- how does it with a Model? Controllers can have multiple Models, which makes it seem like a Model is less a "database table" than it is a unique Entity. So, in very rough terms, which is better? No "Model" really ... class MyController { public function index() { $repo = new PostRepository(); $posts = $repo->findAllByDateRange('within 30 days'); foreach($posts as $post) { echo $post->Author; } } } Or this, which has a Model as the DAO? class MyController { public function index() { $model = new PostModel(); // maybe this returns a PostRepository? $posts = $model->findAllByDateRange('within 30 days'); while($posts->getNext()) { echo $posts->Post->Author; } } } Both those examples didn't even do what I was describing above. I'm clearly lost. Any input?

• Key Tips in WPF

  - by Brad Leach

  Office 2007 and the Ribbon introduced the concept of "Key Tips". In short, every single command in the Ribbon receives a letter which you can press to activate that command. ... The letters are indicated by small "KeyTips" which indicate the letter to press to activate the control. KeyTips are displayed using the Alt key, so using them feels similar to how menu navigation works in Windows. (Source: http://blogs.msdn.com/jensenh/archive/2006/04/12/574930.aspx) An example of the Key Tips can be shown as follows. In this diagram, the use has pressed the ALT key, and is awaiting further input. Are there any WPF Open Source examples of "Key Tips"? How would you go about implementing something like this feature in a generic way (i.e. not requiring a Ribbon)? How would you implement this using a MVVM pattern (given that ICommand does not support InputBindings). Note: ActiPro have implemented this feature in their implementation of a Ribbon, but they have not released source code.

• What is the proper way to URL encode Unicode characters?

  - by Josh Gibson

  I know of the non-standard %uxxxx scheme but that doesn't seem like a wise choice since the scheme has been rejected by the W3C. Some interesting examples: The heart character. If I type this into my browser: http://www.google.com/search?q=? Then copy and paste it, I see this URL http://www.google.com/search?q=%E2%99%A5 which makes it seem like Firefox (or Safari) is doing this. urllib.quote_plus(x.encode("latin-1")) '%E2%99%A5' which makes sense, except for things that can't be encoded in Latin-1, like the triple dot character. … If I type the URL http://www.google.com/search?q=… into my browser then copy and paste, I get http://www.google.com/search?q=%E2%80%A6 back. Which seems to be the result of doing urllib.quote_plus(x.encode("utf-8")) which makes sense since … can't be encoded with Latin-1. But then its not clear to me how the browser knows whether to decode with UTF-8 or Latin-1. Since this seems to be ambiguous: In [67]: u"…".encode('utf-8').decode('latin-1') Out[67]: u'\xc3\xa2\xc2\x80\xc2\xa6' works, so I don't know how the browser figures out whether to decode that with UTF-8 or Latin-1. What's the right thing to be doing with the special characters I need to deal with?

• Community License Agreement for Commercial (SaaS) software?

  - by indomitablehef

  I've got a commercial SaaS application, an online collaboration/lean project mgmt tool. I want to offer a "Community Edition", with specific limitations on how the software can be used, for free. For example free for groups using it to manage open source projects free to K-12 teachers to use in the classroom free for authors collaborating on Lean/Kanban/AgileSoftwareDevelopment books and research papers. free for community conference organizers, user group organizers, etc. The license would grant use of the software with limitations. The software itself can enforce limitations on the number of users/projects. I'm looking for a license agreement / EULA that I can use to specify what uses the software can be used for (see above). It would restrict the users from using it in different ways, such as for commercial use, managing consulting projects, client work, etc. I've been combing the web for good examples of such agreements, and so far coming up short. Any ideas? To be clear, this would not be an open source license of any kind. It would cover the use of commercial software, for specific "community" uses, as we define them.

• slot function not getting called

  - by chappar

  I am learning QT and trying out some examples. I am trying to make a dialog that disappears a label when a button is pressed and makes it appear when the same button is pressed again. Below is the code. #include <QApplication> #include <QPushButton> #include <QLabel> #include <QDialog> #include <QObject> #include <QHBoxLayout> int main(int argc, char ** argv) { QApplication app(argc, argv); QDialog *dialog = new QDialog; QPushButton *testButton = new QPushButton(QObject::tr("test")); QLabel * testLabel = new QLabel (QObject::tr("test")); QHBoxLayout * layout = new QHBoxLayout; layout->addWidget(testButton); layout->addWidget(testLabel); QObject::connect(testButton, SIGNAL(toggled(bool)), testLabel, SLOT(setVisible(bool))); dialog->setLayout(layout); dialog->show(); return app.exec(); } It is not working. Whenever i press the test button nothing happens. But if i change the signal slot connections as QObject::connect(testButton, SIGNAL(clicked(bool)), testLabel, SLOT(setVisible(bool))); it makes the label disappear. So, why it is not working with signal "toggled". What i am guessing is, it is not able to find that signal. Can you guys throw some light?

• Interface Builder caching bad data (voodoo)

  - by Ryan Townshend

  Sometimes IB will hold onto old or bad references, and I cannot seem to remove or edit them. EDIT I have made this a wiki question with the intention of gathering more data on the phenomenon. Answers involving situations where other coders have encountered this are welcome. This happened to me again last night with a table controller. When I created a spike project to try and reproduce the error, the system worked the way I anticipated. Then back in the actual project the bad behavior continued, even if I remove the xib file and all controllers involved. Creating a whole new project with none of the original (problematic) xib and nib files worked correctly. This question is not about the specifics of this incident but about this type of incident in IB. Does anyone know more about this type of bad IB behaviour, and possibly a more stylish way to to eliminate it than nuking the project? Note, removing the offending IB files and recreating them in the same project has not solved this for me in the past, only whole new projects. Answers regarding examples of when/how this glitch has been observed/created are welcome as well.

• How to send complex types from PHP SoapClient to ASP.NET SOAP server?

  - by xaguilars

  Hello I'm having problems sending arrays, structs and arrays of structs from PHP to an ASP.NET SOAP server... Anyone have a sollution for this? I've googled for days and any sollution worked for me. Perphaps I'm forgetting something... There are examples of my code: $client = new SoapClient($options); $pCriteria = new stdClass(); $pCriteria->type=1; $pCriteria->capacity=4; //Test 1 (fail): $resp = $client->GetRooms(array("pCriteria"=>$pCriteria)); //Test 2 (fail): $resp = $client->GetRooms(array("pCriteria"=>new SoapVar($pCriteria, SOAP_ENC_OBJECT, "TCriteria", "http://www.w3.org/2001/XMLSchema"))); print_r($resp); I don't know how to code functions that require an array of TCriteria (TCriteria[], TCriteria_Array type) either... i've tried sending the raw array, a SoapVar with SOAP_ENC_ARRAY encoding and TCriteria_Array type, ... but it does not work (the SOAP server becomes unavaiable and needs to be restarted). I've tried creating classes for the complex types too, instead of stdClass, but not working. I don't know where's the problem. The server admins cannot help me and I haven't found any sollution over internet. I'm a bit desperate hehe. Can you help me please? Can you provide samples of code with the three cases (array of simple data, array of struct and struct) ? Thanks!

• How to design Models the correct way: Object-oriented or "Package"-oriented?

  - by ajsie

  I know that in OOP you want every object (from a class) to be a "thing", eg. user, validator etc. I know the basics about MVC, how they different parts interact with each other. However, i wonder if the models in MVC should be designed according to the traditional OOP design, that is to say, should every model be a database/table/row (solution 2)? Or is the intention more like to collect methods that are affecting the same table or a bunch of related tables (solution 1). example for an Address book module in CodeIgniter, where i want be able to "CRUD" a Contact and add/remove it to/from a CRUD-able Contact Group. Models solution 1: bunching all related methods together (not real object, rather a "package") class Contacts extends Model { function create_contact() {) function read_contact() {} function update_contact() {} function delete_contact() {} function add_contact_to_group() {} function delete_contact_from_group() {} function create_group() {} function read_group() {} function update_group() {} function delete_group() {} } Models solution 2: the OOP way (one class per file) class Contact extends Model { private $name = ''; private $id = ''; function create_contact() {) function read_contact() {} function update_contact() {} function delete_contact() {} } class ContactGroup extends Model { private $name = ''; private $id = ''; function add_contact_to_group() {} function delete_contact_from_group() {} function create_group() {} function read_group() {} function update_group() {} function delete_group() {} } i dont know how to think when i want to create the models. and the above examples are my real tasks for creating an Address book. Should i just bunch all functions together in one class. then the class contains different logic (contact and group), so it can not hold properties that are specific for either one of them. the solution 2 works according to the OOP. but i dont know why i should make such a dividing. what would the benefits be to have a Contact object for example. Its surely not a User object, so why should a Contact "live" with its own state (properties and methods). you experienced guys with OOP/MVC, please shed a light on how one should think here in this very concrete task.

• How do I represent concurrent actions in jBPM, any of which can end a process?

  - by tpdi

  An example: a permit must be examined by two lawyers and one engineer. If any of those three reject it, the process enters a "rejected" end state. If all three grant the permit, it enters a "granted" end state. All three examiners may examine simultaneously, or in any order. Once one engineer has granted it, it shouldn't be available to be examined by an engineer; once two lawyers have examined it, it shouldn't be available to lawyers; once one engineer and two lawyers have examined it should go to the granted end state. My initial thinking is that either I have a overly complicated state transition diagram, with "the same" intermediate states multiply repeated, or I carry (external) state with the process { bool rejected; int engineerSignoffId; int lawyer1SignoffId; int lawyer2SignoffId}. Or something like this? If so, how does the engineer's rejection terminate the subprocess that is in "Lawyers"? START->FORK->Engineer->Granted?---------------->Y->JOIN-->Granted |->Lawyers-->Granted?->by 2 lawyers?->Y---^ ^ | |--------------------------N What's the canonical jBPM answer to this? Can you point me to examples or documentation of such answers? Thanks.

• Obtaining Current Fiscal Year from Hierarchy with MDX

  - by Robert Iver

  I'm building a report in Reporting Services 2005 based on a SSAS 2005 cube. The basic idea of the report is that they want to see sales for this fiscal year to date vs. last year sales year to date. It sounds simple, but being that this is my first "real" report based on SSAS, I'm having a hell of a time. First, how would one calculate the current fiscal year, quarter, or month. I have a Fiscal Date Hierarchy with all that information in it, but I can't figure out how to say: "Based on today's date, find the current fiscal year, quarter, and month." My second, but slightly smaller problem, is getting last years sales vs. this years sales. I have seen MANY examples on how to do this, but they all assume that you select the date manually. Since this is a report and will run pretty much on it's own, I need a way to insert the "current" fiscal year, quarter, and month into the PERIODSTODATE or PARALLELPERIOD functions to get what I want. So, I'm begging for your help on this one. I have to have this report done by tomorrow monring and I'm beginning to freak out a bit. Thanks in advance.

• Filling SWT table object using a separated thread class ...

  - by erlord

  Hi all I've got a code snippet by the swt team that does exactly what I need. However, there is a part I want to separate into another class, in particular, the whole inline stuff. In response to my former question, it has been suggested that Callable should be used in order to implement threaded objects. It is suggested to make use of an implementation of runnable or better callable, since I do need some kind of return. However, I don't get it. My problems are: In the original code, within the inline implementation of the method run, some of the parents objects are called. How would I do this when the thread is separated? Pass the object via the C'tor's parameter? In the original code, another runnable object is nested within the runnable implementation. What is it good for? How to implement this when having separated the code? Furthermore, this nested runnable again calls objects created by the main method. Please, have mercy with me, but I am still quite a beginner and my brain is near collapsing :-( All I want is to separate all the threaded stuff into another class and make the program do just the same thing as it already does. Help please! Again thank you very much in advance for any useful suggestions, hints, examples etc... Regs Me

• Treetop basic parsing and regular expression usage

  - by ucint

  I'm developing a script using the ruby Treetop library and having issues working with its syntax for regex's. First off, many regular expressions that work in other settings dont work the same in treetop. This is my grammar: (myline.treetop) grammar MyLine rule line string whitespace condition end rule string [\S]* end rule whitespace [\s]* end rule condition "new" / "old" / "used" end end This is my usage: (usage.rb) require 'rubygems' require 'treetop' require 'polyglot' require 'myline' parser = MyLineParser.new p parser.parse("randomstring new") This should find the word new for sure and it does! Now I wont to extend it so that it can find new if the input string becomes "randomstring anotherstring new yetanother andanother" and possibly have any number of strings followed by whitespace (tab included) before and after the regex for rule condition. In other words, if I pass it any sentence with the word "new" etc in it, it should be able to match it. So let's say I change my grammar to: rule line string whitespace condition whitespace string end Then, it should be able to find a match for: p parser.parse("randomstring new anotherstring") So, what do I have to do to allow the string whitespace to be repeated before and after condition? If I try to write this: rule line (string whitespace)* condition (whitespace string)* end , it goes in an infinite loop. If i replace the above () with [], it returns nil In general, regex's return a match when i use the above, but treetop regex's dont. Does anyone have any tips/points on how to go about this? Plus, since there isn't much documentation for treetop and the examples are either too trivial or too complex, is there anyone who knows a more thorough documentation/guide for treetop?
