• Programatically Determining Bin Path

  - by Andy

  I'm working on a web app called pj and there is a bin file and a src folder. The relative paths before I deploy the app will look something like: pj/bin and pj/src/pj/script.py. However, after deployment, the relative paths will look like: pj_dep/deployed/bin and pj_dep/deployed/lib/python2.6/site-packages/pj/script.py Question: Within script.py, I am trying to find the path of a file in the bin directory. This leads to 2 different behaviors in the dev and deployment environment. If I do os.path.join(os.path.dirname(__file__), 'bin') to try to get the path for the dev environment, I will have a different path for the deployment environment. Is there a more generalized way I can find the bin directory so that I do not need to rely on an if statement to determine how many directories to go up based on the current env? This doesn't seem flexible and might cause other issues later on when the code is moved.

• What makes WPF application startup slow?

  I noticed that WPF application startup is sometimes pretty slow. Does anybody know if the the cause is the elements initialization or DLLs loading or something else?

• Export view data programmatically in Access/SQL Server

  - by andy

  We have an Access application front-end connected to a SQL Server 2000 database. We would like to be able to programmatically export the results of some views to whatever format we can (ideally Excel, but CSV / tab delimited is fine). Up until now we've just hit F11, opened up the view, and hit File-Save As, but we're starting to get results with more than 16,000 results, which can't be exported. I'd like some sort of server side stored procedure we can trigger that will do this. I'm aware of the sp_makewebtask procedure that does this, however it requires administrative rights on the server, and for obvious reasons we can't give that to everyone. Any ideas?

• How to programatically set cell.textLabel.text from a different view?

  - by Andy

  I've got a view controller, call it VC1, that's a table view. When I tap a cell in the table view, I am presented with a new view controller, call it VC2, which is a short list of choices. After making a choice, I want to dismiss VC2 and set the cell.textLabel.text property of the VC1 cell I originally tapped to the value I selected in VC2. Conceptually speaking, what is the proper way to do this? I've tried a handful of different approaches, but all of them seem wonky at best, and only one of them actually worked - although it was the most cumbersome of all, passing references to both view controllers and table view cells and all kinds of things. It just feels like I'm making a mountain out of what is probably a mole hill. This is such a common paradigm that I find it hard to believe there's not a simple method for doing it. Thanks in advance for any input you can offer.

• problem in html, table class text stretching out.

  - by Andy

  Hey people, I've got a slight problem after weeks of html programming. I've got a large table which I use to construct tabs with, details don't really matter. On every tab there is a tab title (which is defined as one single cell in a table with a class from a .css) and under it there are other rows and columns for the table. sample code for the single table with the single cell in it: <table class='tabcontainer_title'><tr><td class='tabcontainer_title'>TEXT</td></tr></table> This table is again positioned in one cell of the table outside it, which has a different class 'tabcontainer_content' This is in the CSS: .tabcontainer_title{ background-color : #58af34; background-image : url(); text-align : right; vertical-align : top; margin-top : 0px; margin-right : 0px; margin-bottom : 0px; margin-left : 0px; padding-top : 5px; padding-right : 10px; padding-bottom : 5px; padding-left : 0px; font-size : 14px; font-style : normal; color : #000000; } .tabcontainer_content{ width : 100%; font-weight : bolder; background-color : #58af34; color : #000000; padding : 0px; border-collapse : collapse; } The problem I'm experiencing right now is that if there are like 3 rows in the table, which means there's a lot of emtpy space instead of those rows, the text in the tab title has a large margin from the top: but I haven't configured any margin to be present. When the table is full of rows though, hence the table is full, then the tab title holds no unnecessary empty space above the text. What am I missing here?

• Should I use static_cast or reinterpret_cast when casting a void* to whatever

  - by Andy

  Both static_cast and reinterpret_cast seem to work fine for casting void* to another pointer type. Is there a good reason to favor one over the other?

• Using DataTypeAttribute to validate a date

  - by Andy Evans

  I'm having some difficulty understanding how to validate a date (DOB) using MVC2. What I want to do is 1. Is the date entered a valid date and, 2. Is the date at lease 13 years in the past. For example, to validate an email I use the following code: [Required(ErrorMessage = "Email address is required.")] [StringLength(320, ErrorMessage = "Email must be less than 320 characters.")] [Email(ErrorMessage = "This email address is invalid.")] public string email { get; set; } To validate the email I use: public class EmailAttribute : RegularExpressionAttribute { public EmailAttribute() : base("insert long regex expression here") { } } Any assistance would be greatly appreciated, thanks!

• fix a columns width when a list is bound to a datagridview

  - by Andy

  I have a list that I have bound to a datagridview. I want the first column to be a fixed size. The data is bound to the dataGridView and I can't seem to find a way to access an individual colums properties. if I try myDatagridview.colums[0] I get an index out of bounds, since it says the columns count is 0. private DataGridView setUpDataGrid(List<NVRlineVal> _NVRData) { //setup dataGridView DataGridView NVRDataGridView = new System.Windows.Forms.DataGridView(); NVRDataGridView.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize; NVRDataGridView.Dock = System.Windows.Forms.DockStyle.Fill; NVRDataGridView.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill; NVRDataGridView.Location = new System.Drawing.Point(3, 3); NVRDataGridView.Name = "NVRDataGridView" + nvrIndex; NVRDataGridView.RowHeadersWidthSizeMode = System.Windows.Forms.DataGridViewRowHeadersWidthSizeMode.AutoSizeToDisplayedHeaders; NVRDataGridView.Size = new System.Drawing.Size(380, 401); NVRDataGridView.TabIndex = 0; NVRDataGridView.DataSource = _NVRData; var test = NVRDataGridView.Columns; NVRDataGridView.DataMember = "devState"; DataGridViewAutoSizeColumnMode.None; } Any ideas on how to have a fixed column width for only one of these columns, the rest will autosize?

• posted recv buffers returned syncronously or async after calling rdma_disconnect()

  When calling rdma_disconnect(), do I get completion queue events for all posted recv work requests before rdma_disconnect() returns, or should I expect them to come in after rdma_disconnect() has returned?

• tfs : branch moved folder based on label or date

  - by Andy

  I've moved a folder in tfs using the "move" command but now I cannot create branches off the moved folder based on date or label (label was created when source was in the old folder). I can however create a branch based on "latest version". I get an error message "no items match in if I try to branch of a label. I'm guessing the label references files using the old folder before I moved it. I also get no files if I try to "get specific version" by either date or label. I've tried to roll back moving the folder but this gives me errors such as "An unexpected error occured".

• WPF - Correct Syntax for Using Coverter with Current Binding

  - by Andy T

  Hi, I have a collection of hex strings that represent colours and I am binding a combobox's ItemsSource to that collection. The combobox items are templated to have a filled rectangle with the relevant colour. I therefore need to use a converter to convert the hex value to a string. Easy enough. However, Blend is telling me that this syntax is incorrect in my XAML: Fill="{Binding, Converter={StaticResource StringToBrush}}" Apparently, I can't use a converter against plain old 'Binding'. Blend says that something like this is syntactically correct: Fill="{Binding Value, Converter={StaticResource StringToBrush}}" ...However that obviously doesn't work. I'm not quite au fait with binding syntax yet, so obviously I'm getting it wrong. Can anyone advise the correct syntax to achieve what I'm trying to do (convert my bound String using the coverter StringToBrush)? Thanks in advance! AT

• SOLR not searching on certain fields

  - by andy

  hey guys, just installed solr, edited the schema.xml, and am now trying to index it and search on it with some test data. In the XML file I'm sending to SOLR, one of my fields look like this: <field name="PageContent"><![CDATA[<p>some text in a paragrah tag</p>]]></field> There's HTML there, so I've wrapped it in CDATA. In my SOLR schema.xml, the definition for that field looks like this: <field name="PageContent" type="text" indexed="true" stored="true"/> When I ran the POSTing tool, everything went ok, but when I search for content which I know is inside the PageContent field, I get no results. However, when I set the node to PageContent, it works. But if I set it to any other field, it doesn't search in PageContent. Am I doing something wrong? what's the issue? thanks very much for any help cheers! UPDATE Just to clarify on the error. I've uploaded a "doc" with the following data: <field name="PageID">928</field> <field name="PageName">some name</field> <field name="PageContent"><![CDATA[<p>html content</p>]]></field> In my schema I've defined the fields as such: <field name="PageID" type="integer" indexed="true" stored="true" required="true"/> <field name="PageName" type="text" indexed="true" stored="true"/> <field name="PageContent" type="text" indexed="true" stored="true"/> And: <uniqueKey>PageID</uniqueKey> <defaultSearchField>PageName</defaultSearchField> Now, when I use the Solr admin tool and search for "some name" I get a result. But, if I search for "html content", or "html", or "content", or "928", I get no results why? cool, thanks!

• [FreeBSD kernel ]How to maintain a linked list on kernel lever?

  - by Andy Leman

  The situation is: I will implement sets of new system calls. Each of them need to access (read or write) a linked list. So, that means I will have several C programs. So, how can I maintain a linked list in memory and let several programs access it? Or,this is wrong....I should save it as a file? (but I hardly think this is a good idea).. A lot of confused questions here...Need help. Thank you indeed!

• Java Concurrency in practice sample question

  - by andy boot

  I am reading "Java Concurrency in practice" and looking at the example code on page 51. This states that if a thread has references to a shared object then other threads may be able to access that object before the constructor has finished executing. I have tried to put this into practice and so I wrote this code thinking that if I ran it enough times a RuntimeException("World is f*cked") would occur. But it isn't doing. Is this a case of the Java spec not guaranting something but my particular implementation of java guaranteeing it for me? (java version: 1.5.0 on Ubuntu) Or have I misread something in the book? Code: (I expect an exception but it is never thrown) public class Threads { private Widgit w; public static void main(String[] s) throws Exception { while(true){ Threads t = new Threads(); t.runThreads(); } } private void runThreads() throws Exception{ new Checker().start(); w = new Widgit((int)(Math.random() * 100) + 1); } private class Checker extends Thread{ private static final int LOOP_TIMES = 1000; public void run() { int count = 0; for(int i = 0; i < LOOP_TIMES; i++){ try { w.checkMe(); count++; } catch(NullPointerException npe){ //ignore } } System.out.println("checked: "+count+" times out of "+LOOP_TIMES); } } private static class Widgit{ private int n; private int n2; Widgit(int n) throws InterruptedException{ this.n = n; Thread.sleep(2); this.n2 = n; } void checkMe(){ if (n != n2) { throw new RuntimeException("World is f*cked"); } } } }

• SOLR and Natural Language Parsing - Can I use it?

  - by andy

  hey guys, my requirements are pretty similar to this: Requirements http://stackoverflow.com/questions/90580/word-frequency-algorithm-for-natural-language-processing Using Solr While the answer for that question is excellent, I was wondering if I could make use of all the time I spent getting to know SOLR for my NLP. I thought of SOLR because: It's got a bunch of tokenizers and performs a lot of NLP. It's pretty use to use out of the box. It's restful distributed app, so it's easy to hook up I've spent some time with it, so using could save me time. Can I use Solr? Although the above reasons are good, I don't know SOLR THAT well, so I need to know if it would be appropriate for my requirements. Ideal Usage Ideally, I'd like to configure SOLR, and then be able to send SOLR some text, and retrieve the indexed tonkenized content. Context So you guys know, I'm working on a small component of a bigger recommendation engine.

• Scraping Google docs (can't use API)

  - by Andy Waite

  I'm building an iPhone app which needs a peice of meta data from a user's Google Spreadsheet. Unfortunately the meta data I need is not exposed by the API, so I will need to scrape it from the document's HTML source (it would not be present in any of the exported variants). Is there anyway to include authentication parameters in a call such as: http://spreadsheets.google.com/ccc?key=abc123&username=...&password=...

• Public code repository

  - by Andy White

  Can anyone recommend a public code repository? A few friends and I are thinking of starting a few projects for iPhone, web, Android, etc., and it would be nice to have a public (internet) code repository to use that would work well on any platform (Mac, PC, Linux). Any type of repository is fine (SVN, CVS, Git, etc.). A few ideas are Sourceforge or Google Code. Any recommendations? Thanks

• How to improve multi-threaded access to Cache (custom implementation)

  - by Andy

  I have a custom Cache implementation, which allows to cache TCacheable<TKey> descendants using LRU (Least Recently Used) cache replacement algorithm. Every time an element is accessed, it is bubbled up to the top of the LRU queue using the following synchronized function: // a single instance is created to handle all TCacheable<T> elements public class Cache() { private object syncQueue = new object(); private void topQueue(TCacheable<T> el) { lock (syncQueue) if (newest != el) { if (el.elder != null) el.elder.newer = el.newer; if (el.newer != null) el.newer.elder = el.elder; if (oldest == el) oldest = el.newer; if (oldest == null) oldest = el; if (newest != null) newest.newer = el; el.newer = null; el.elder = newest; newest = el; } } } The bottleneck in this function is the lock() operator, which limits cache access to just one thread at a time. Question: Is it possible to get rid of lock(syncQueue) in this function while still preserving the queue integrity?

• SQL Server 2008 GUID column is all 0's

  - by Andy Evans

  I'm hoping this is a simple goof I did on my end ... I have a table in my database set up like so: column name: widget_guid data type: uniqueidentifier allow nulls: false default value: newid() identity: false row guid: true When records are created (via LINQ to SQL) that the values in this field are formatted as a GUID but contain all 0's My assumption was that when a new record was created, that a guid would be autogenerated for that column, much like an auto-incrementing row id. Is this not true? Any help would be greatly appreciated. Thanks.

• How to paste transparent image into flash project

  Hi, I've created a short text (a word) in photoshop with the blending options I prefer and now it's all done I would like to paste it into my flash project. The problem is I can't get the text to be transparent in the flash, I always see the white background which is not very nice since the background on which the text will show is actually a picture. How to make this text transparent? In photoshop I started a new transparent project. Copying from a .GIF file also doesn't work... Thanks!!

• Using lambda expressions and linq

  - by Andy

  So I've just started working with linq as well as using lambda expressions. I've run into a small hiccup while trying to get some data that I want. This method should return a list of all projects that are open or in progress from Jira Here's the code public static List<string> getOpenIssuesListByProject(string _projectName) { JiraSoapServiceService jiraSoapService = new JiraSoapServiceService(); string token = jiraSoapService.login(DEFAULT_UN, DEFAULT_PW); string[] keys = { getProjectKey(_projectName) }; RemoteStatus[] statuses = jiraSoapService.getStatuses(token); var desiredStatuses = statuses.Where(x => x.name == "Open" || x.name == "In Progress") .Select(x=>x.id); RemoteIssue[] AllIssues = jiraSoapService.getIssuesFromTextSearchWithProject(token, keys, "", 99); IEnumerable<RemoteIssue> openIssues = AllIssues.Where(x=> { foreach (var v in desiredStatuses) { if (x.status == v) return true; else return false; } return false; }); return openIssues.Select(x => x.key).ToList(); } Right now this only select issues that are "Open", and seems to skip those that are "In Progress". My question: First, why am I only getting the "Open" Issues, and second is there a better way to do this? The reason I get all the statuses first is that the issue only stores that statuses ID, so I get all the statuses, get the ID's that match "Open" and "In Progress", and then match those ID numbers to the issues status field.
