• UITableView UITableViewCell dynamic UILabel Height storyboard

  - by Mikel Nelson

  This isn'an a question, just a results log on an issue I had with XCode 4.5 storyboards and dynamic height UITableCell with a UILabel. The issue was; the initial display of a cell would only show part of the resized UILabel contents, and that the visual UILabel was not resized. It would only display correctly after scrolling off the top of the Table and back down. I did the calculations in hieghtForRowAtIndexPath and sizeToFit the UILabel in rowAtIndexPath. The sizes where coming up ok in debug, but the device was not updating the display with the correct size and UILable.text value. I had created the dynamic UITableCell in a storyboard. However, I had set the width and height to a nominal value (290x44). It turns out, this was causing my issues. I set the width and height to zero (0) in the story board, and everything started working correctly. (i.e. the UILabels displayed at the correct size with full content). I was unable to find anything online on this issue, except for some references to creating the custom table cell with a frame of zero. Turns out, that was really the answer (for me).

• How to use PHP preg_replace regular expression to find and replace text

  - by Roger

  I wrote this PHP code to make some substitutions: function cambio($txt){ $from=array( '/\+\>([^\+\>]+)\<\+/', //finds +>text<+ '/\%([^\%]+)\%/', //finds %text% ); $to=array( '<span class="P">\1</span>', '<span>\1</span>', ); return preg_replace($from,$to,$txt); } echo cambio('The fruit I most like is: +> %apple% %banna% %orange% <+.'); Resulting into this: The fruit I most like is: <span class="P"> <span>apple</span> <span>banna</span> <span>orange</span> </span>. however I needed to identify the fruit's span tags, like this: The fruit I most like is: <span class="P"> <span class="a">apple</span> <span class="b">banna</span> <span class="c">coco</span> </span>. I'd buy a fruit to whom discover a regular expression to accomplish this :-)

• Speeding up PostgreSQL query where data is between two dates

  - by Roger

  I have a large table ( 50m rows) which has some data with an ID and timestamp. I need to query the table to select all rows with a certain ID where the timestamp is between two dates, but it currently takes over 2 minutes on a high end machine. I'd really like to speed it up. I have found this tip which recommends using a spatial index, but the example it gives is for IP addresses. However, the speed increase (436s to 3s) is impressive. How can I use this with timestamps?

• getting a "default" concrete class that implements an interface

  - by Roger Joys

  I am implementing a custom (and generic) Json.net serializer and hit a bump in the road that I could use some help on. When the deserializer is mapping to a property that is an interface, how can I best determine what sort of object to construct to deserialize to to place into the interface property. I have the following: [JsonConverter(typeof(MyCustomSerializer<foo>))] class foo { int Int1 { get; set; } IList<string> StringList {get; set; } } My serializer properly serializes this object, and but when it comes back in, and I try to map the json parts to to object, I have a JArray and an interface. I am currently instantiating anything enumerable like List as theList = Activator.CreateInstance(property.PropertyType); This works create to work with in the deserialization process, but when the property is IList, I get runtime complaints (obviously) about not being able to instantiate an interface. So how would I know what type of concrete class to create in a case like this? Thank you

• HTML divs can go outside browser window??

  - by Nelson

  I was playing around with ASP.NET Web Parts which has a "drop down" div. It's all the way to the right of the page. When I click to bring it up, it goes off the window. Usually anything off the viewable area will trigger the bottom scrollbars. How is this possible? See screenshot: http://i42.tinypic.com/4sejww.png

• If we make a number every millisecond, how much data would we have in a day?

  - by Roger Travis

  I'm a bit confused here... I'm being offered to get into a project, where would be an array of certain sensors, that would give off reading every millisecond ( yes, 1000 reading in a second ). Reading would be a 3 or 4 digit number, for example like 818 or 1529. This reading need to be stored in a database on a server and accessed remotely. I never worked with such big amounts of data, what do you think, how much in terms of MBs reading from one sensor for a day would be?... 4(digits)x1000x60x60x24 ... = 345600000 bits ... right ? about 42 MB per day... doesn't seem too bad, right? therefor a DB of, say, 1 GB, would hold 23 days of info from 1 sensor, correct? I understand that MySQL & PHP probably would not be able to handle it... what would you suggest, maybe some aps? azure? oracle? ... Thansk!

• iOS: click counter for row in tableview

  - by roger.arliner21

  I am developing and tableView in which in each row I have to display the click counter and row number.Each cell must have an initial click counter value of 0 when application is initialized. Then increment the click counter value within a cell whenever a user clicks on the cell. I have take 26 fixed rows. I have taken tableData.plist file as in the attached image. I am initializing the self.dataArray with the plist . Now I want to do implementation in the didSelectRowAtIndexPath delegate method,if any row is tapped that row's click counter should increment. - (void)viewDidLoad { [super viewDidLoad]; NSString *path = [[NSBundle mainBundle] pathForResource:@"tableData" ofType:@"plist"]; self.dataArray = [NSMutableArray arrayWithContentsOfFile:path];//array initialized with plist } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [self.dataArray count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *kCustomCellID = @"MyCellID"; UILabel *label1 = [[UILabel alloc] initWithFrame:CGRectMake(160.0f, 2.0f, 30.0f, 20.0f)]; UILabel *label2 = [[UILabel alloc] initWithFrame:CGRectMake(160.0f, 24.0f, 30.0f, 30.0f)]; label2.textColor = [UIColor grayColor]; UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:kCustomCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:kCustomCellID] autorelease]; cell.selectionStyle = UITableViewCellSelectionStyleNone; } if([self.dataArray count]>indexPath.row) { label1.text = [[self.dataArray objectAtIndex:indexPath.row] objectForKey:@"Lable1"]; label2.text =[[self.dataArray objectAtIndex:indexPath.row] objectForKey:@"Lable2"]; } else { label1.text = @""; label2.text =@""; } [cell.contentView addSubview:label1]; [cell.contentView addSubview:label2]; [label1 release]; [label2 release]; return cell; } #pragma mark - #pragma mark Table view delegate - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //implementation for row counter incrementer. }

• Displaying success/failure messages from hidden iframe submit

  - by Erik Nelson

  I'm using the hidden iframe method to submit a form with a file upload field. I want to display a message back on the page using javascript and I'm not sure how to do this. If this was just a form with text fields I'd do an AJAX post and respond with a message I'd display in my callback function. I'm just not sure how to accomplish this same task with the hidden iframe method since it is a standard form post.

• PropertyInfo SetValue and nulls

  - by Nelson

  If I have something like: object value = null; Foo foo = new Foo(); PropertyInfo property = Foo.GetProperties().Single(p => p.Name == "IntProperty"); property.SetValue(foo, value, null); Then foo.IntProperty gets set to 0, even though value = null. It appears it's doing somemething like IntProperty = default(typeof(int)). I would like to throw an InvalidCastException if IntProperty is not a "nullable" type (Nullable< or reference). I'm using Reflection, so I don't know the type ahead of time. How would I go about doing this?

• F# pattern matching when mixing DU's and other values

  - by Roger Alsing

  What would be the most effective way to express the following code? match cond.EvalBool() with | true -> match body.Eval() with | :? ControlFlowModifier as e -> match e with | Break(scope) -> e :> obj //Break is a DU element of ControlFlowModifier | _ -> next() //other members of CFM should call next() | _ -> next() //all other values should call next() | false -> null cond.EvalBool returns a boolean result where false should return null and true should either run the entire block again (its wrapped in a func called next) or if the special value of break is found, then the loop should exit and return the break value. Is there any way to compress that block of code to something smaller?

• PHP form post, automatically mapping to an object (model binding)

  - by Pete Nelson

  I do a lot of ASP.NET MVC 2 development, but I'm tackling a small project at work and it needs to be done in PHP. Is there anything built-in to PHP to do model binding, mapping form post fields to a class? Some of my PHP code currently looks like this: class EntryForm { public $FirstName = ""; public $LastName = ""; } $EntryForm = new EntryForm(); if ($_POST && $_POST["Submit"] == "Submit") { $EntryForm->FirstName = trim($_POST["FirstName"]); $EntryForm->LastName = trim($_POST["LastName"]); } Is there anything built-in to a typical PHP install that would do such mapping like you'd find in ASP.NET MVC, or does it require an additional framework?

• Problems updating a textBox ASP.NET

  - by Roger Filipe

  Hello, I'm starting in asp.net and am having some problems that I do not understand. The problem is this, I am building a site for news. Every news has a title and body. I have a page where I can insert news, this page uses a textbox for each of the fields (title and body), after clicking the submit button everything goes ok and saves the values in the database. And o have another page where I can read the news, I use labels for each of the camps, these labels are defined in the Page_Load. Now I'm having problems on the page where I can edit the news. I am loading two textboxes (title and body) in the Page_Load, so far so good, but then when I change the text and I click the submit button, it ignores the changes that I made in the text and saves the text loaded in Page_Load. This code doesn't show any database connection but you can understand what i'm talking about. protected void Page_Load(object sender, EventArgs e) { textboxTitle.Text = "This is the title of the news"; textboxBody.Text = "This is the body of the news "; } I load the page, make the changes in the text , and then click submit. protected void btnSubmit_Click(object sender, EventArgs e) { String title = textboxTitle.Text; String body = textboxBody.Text; Response.Write("Title: " + title + " || "); Response.Write("Body: " + body ); } Nothing happens, the text in the textboxes is always the one I loaded in the page_load, how do I update the Text in the textboxes?

• Updating or inserting high scores in SQL

  - by Roger Gilbrat

  I've been racking my brain over this for the past few days and I'm not sure it's possible, but figured I ask here. Is it possible for a single SQL statement to update a high score if your score is greater or insert it if your first score? My Score table has a UserID, Level and Score columns and I like it to follow the following logic: If your new score is greater than your last score for this Level, then replace it. If you don't have a score for this Level then add it. If your score for this Level is less than your highest score for this Level then do nothing. Is this possible in a single SQL statement or do I have to use two, one to see if you have a new high score and if so, replace it? Each UserID would have only one score in the table for each Level. I'm using MySQL.

• Putting a dollar value on code quality

  - by Chris Nelson

  As noted in another thread, "In most businesses, code quality is defined in dollars." So my company has an opportunity to acquire a large-ish C code base. Obviously, if the code quality is good, the code base is worth more than if it's poor. That is, if we can readily read, understand, and update the code, it's worth more to us than if it's a spaghetti-coded mess. Without being able to see the code ahead of time, we'd like to set some objective measure as an acceptance criteria like "If the XXX measure is below the price will be discounted YY%." What criteria can we or should we measure and what tool can we use to measure it?

• Where are AnkhSVN CA certificates stored?

  - by Roger Lipscombe

  My Subversion repository is available over HTTPS. I've got a self-signed CA root certificate, and the server uses a certificate signed with that. The CA root certificate is stored in Trusted Root Certification Authorities, which means that (for example) Internet Explorer recognises it. AnkhSVN, on the other hand, reports "There are some problems with this server's certificate". So: what is AnkhSVN using as its certificate store? It doesn't appear to be the Windows one. And how do I put my CA root certificate in there?

• Reading Unicode files line by line C++

  - by Roger Nelson

  What is the correct way to read Unicode files line by line in C++? I am trying to read a file saved as Unicode (LE) by Windows Notepad. Suppose the file contains simply the characters A and B on separate lines. In reading the file byte by byte, I see the following byte sequence (hex) : FE FF 41 00 0D 00 0A 00 42 00 0D 00 0A 00 So 2 byte BOM, 2 byte 'A', 2byte CR , 2byte LF, 2 byte 'B', 2 byte CR, 2 byte LF . I tried reading the text file using the following code: std::wifstream file("test.txt"); file.seekg(2); // skip BOM std::wstring A_line; std::wstring B_line; getline(file,A_line); // I get "A" getline(file,B_line); // I get "\0B" I get the same results using operator instead of getline file >> A_line; file >> B_line; It appears that the single byte CR character is is being consumed only as the single byte. or CR NULL LF is being consumed but not the high byte NULL. I would expect wifstream in text mode would read the 2byte CR and 2byte LF. What am I doing wrong? It does not seem right that one should have to read a text file byte by byte in binary mode just to parse the new lines.

• How are you using C++0x today? [closed]

  - by Roger Pate

  This is a question in two parts, the first is the most important and concerns now: Are you following the design and evolution of C++0x? What blogs, newsgroups, committee papers, and other resources do you follow? Even where you're not using any new features, how have they affected your current choices? What new features are you using now, either in production or otherwise? The second part is a follow-up, concerning the new standard once it is final: Do you expect to use it immediately? What are you doing to prepare for C++0x, other than as listed for the previous questions? Obviously, compiler support must be there, but there's still co-workers, ancillary tools, and other factors to consider. What will most affect your adoption? Edit: The original really was too argumentative; however, I'm still interested in the underlying question, so I've tried to clean it up and hopefully make it acceptable. This seems a much better avenue than duplicating—even though some answers responded to the argumentative tone, they still apply to the extent that they addressed the questions, and all answers are community property to be cleaned up as appropriate, too.

• Recursive wildcards in Rake?

  - by Roger Lipscombe

  Follow up to this question about GNU make: I've got a directory, flac, containing .FLAC files. I've got a corresponding directory, mp3 containing MP3 files. If a FLAC file is newer than the corresponding MP3 file (or the corresponding MP3 file doesn't exist), then I want to run a bunch of commands to convert the FLAC file to an MP3 file, and copy the tags across. The kicker: I need to search the flac directory recursively, and create corresponding subdirectories in the mp3 directory. The directories and files can have spaces in the names, and are named in UTF-8. It turns out that this won't work in make, because of the spaces in the directories and filenames, so I'm wondering how to do it in rake instead...
