• Scroll UITableViewCell above keyboard for small tableview

  - by JK

  I have a tableview which is added to a UIViewController as the tableview only fills the bottom 3/4 of the screen.The rows contain editable UITextFields. When a field is tapped, the keyboard appears but the table does not scroll upwards as would normally be the case. Consequently, the keyboard obscures the field being edited. I have tried calling [tableView scrollToRowAtIndexPath:(NSIndexPath *)indexPath atScrollPosition:(UITableViewScrollPosition)scrollPosition animated:(BOOL)animated] but this has no effect if the table contains only a few rows. How can I get the table to scroll a specific cell above the keyboard? Thank you

• Precision error on matrix multiplication

  - by Wam

  Hello all, Coding a matrix multiplication in my program, I get precision errors (inaccurate results for large matrices). Here's my code. The current object has data stored in a flattened array, row after row. Other matrix B has data stored in a flattened array, column after column (so I can use pointer arithmetic). protected double[,] multiply (IMatrix B) { int columns = B.columns; int rows = Rows; int size = Columns; double[,] result = new double[rows,columns]; for (int row = 0; row < rows; row++) { for (int col = 0; col < columns; col++) { unsafe { fixed (float* ptrThis = data) fixed (float* ptrB = B.Data) { float* mePtr = ptrThis + row*rows; float* bPtr = ptrB + col*columns; double value = 0.0; for (int i = 0; i < size; i++) { value += *(mePtr++) * *(bPtr++); } result[row, col] = value; } } } } } Actually, the code is a bit more complicated : I do the multiply thing for several chunks (so instead of having i from 0 to size, I go from localStart to localStop), then sum up the resulting matrices. My problem : for a big matrix I get precision error : NUnit.Framework.AssertionException: Error at (0,1) expected: <6.4209571409444209E+18> but was: <6.4207619776304906E+18> Any idea ?

• PHP autoloader: ignoring non-existing include

  - by Bart van Heukelom

  I have a problem with my autoloader: public function loadClass($className) { $file = str_replace(array('_', '\\'), '/', $className) . '.php'; include_once $file; } As you can see, it's quite simple. I just deduce the filename of the class and try to include it. I have a problem though; I get an exception when trying to load a non-existing class (because I have an error handler which throws exceptions). This is inconvenient, because it's also fired when you use class_exists() on a non-existing class. You don't want an exception there, just a "false" returned. I fixed this earlier by putting an @ before the include (supressing all errors). The big drawback with this, though, is that any parser/compiler errors (that are fatal) in this include won't show up (not even in the logs), resulting in a hard to find bug. What would be the best way to solve both problems at once? The easiest way would be to include something like this in the autoloader (pseudocode): foreach (path in the include_path) { if (is_readable(the path + the class name)) readable = true; } if (!readable) return; But I worry about the performance there. Would it hurt a lot? (Solved) Made it like this: public function loadClass($className) { $file = str_replace(array('_', '\\'), '/', $className) . '.php'; $paths = explode(PATH_SEPARATOR, get_include_path()); foreach ($paths as $path) { if (is_readable($path . '/' . $file)) { include_once $file; return; } } }

• Multiplication of 2 positive numbers giving a negative result

  - by krandiash

  My program is an implementation of a bloom filter. However, when I'm storing my hash function results in the bit array, the function (of the form f(i) = (a*i + b) % m where a,b,i,m are all positive integers) is giving me a negative result. The problem seems to be in the calculation of a*i which is coming out to be negative. Ignore the print statements in the code; those were for debugging. Basically, the value of temp in this block of code is coming out to be negative and so I'm getting an ArrayOutOfBoundsException. m is the bit array length, z is the number of hash functions being used, S is the set of values which are members of this bloom filter and H stores the values of a and b for the hash functions f1, f2, ..., fz. public static int[] makeBitArray(int m, int z, ArrayList<Integer> S, int[] H) { int[] C = new int[m]; for (int i = 0; i < z; i++) { for (int q = 0; q < S.size() ; q++) { System.out.println(H[2*i]); int temp = S.get(q)*(H[2*i]); System.out.println(temp); System.out.println(S.get(q)); System.out.println(H[2*i + 1]); System.out.println(m); int t = ((H[2*i]*S.get(q)) + H[2*i + 1])%m; System.out.println(t); C[t] = 1; } } return C; } Any help is appreciated.

• PDF writeHTML for rendering tables

  - by sami

  I'm using TCPDF and following this example which uses writeHTML and heredoc syntax to write a table. http://www.tcpdf.org/examples/example_048.phps I'm trying to do though is switch the font using setFont before writing each column. This means I have to break the html and write it on different pieces (see pseudo code). But once I break the HTML like that, it doesn't work, I think because it becomes invalid. writeHTML <tr> writeHTML first column setFont() writeHTML second column writeHTML </tr> I want to use writeHTML because it helps me write the table without having to manually construct. But how can I make modifications before I output each cell?

• Zend_Validate_Abstract custom validator not displaying correct error messages.

  - by Jeremy Dowell

  I have two text fields in a form that I need to make sure neither have empty values nor contain the same string. The custom validator that I wrote extends Zend_Validate_Abstract and works correctly in that it passes back the correct error messages. In this case either: isEmpty or isMatch. However, the documentation says to use addErrorMessages to define the correct error messages to be displayed. in this case, i have attached ->addErrorMessages(array("isEmpty"=>"foo", "isMatch"=>"bar")); to the form field. According to everything I've read, if I return "isEmpty" from isValid(), my error message should read "foo" and if i return "isMatch" then it should read "bar". This is not the case I'm running into though. If I return false from is valid, no matter what i set $this-_error() to be, my error message displays "foo", or whatever I have at index[0] of the error messages array. If I don't define errorMessages, then I just get the error code I passed back for the display and I get the proper one, depending on what I passed back. How do I catch the error code and display the correct error message in my form? The fix I have implemented, until I figure it out properly, is to pass back the full message as the errorcode from the custom validator. This will work in this instance, but the error message is specific to this page and doesn't really allow for re-use of code. Things I have already tried: I have already tried validator chaining so that my custom validator only checks for matches: ->setRequired("true") ->addValidator("NotEmpty") ->addErrorMessage("URL May Not Be Empty") ->addValidator([*customValidator]*) ->addErrorMessage("X and Y urls may not be the same") But again, if either throws an error, the last error message to be set displays, regardless of what the error truly is. I'm not entirely sure where to go from here. Any suggestions?

• ipad dev - in the UISplitViewController template, how is the method setDetailItem called?

  - by Brian

  I am developing an ipad app which has a UISplitViewController. (I use IB to build the interface, but I do not use the template) Both master and detail (left and right) views are navigationController. The left view subclass UITableView and the right view should push another controller if the cell on the left is selected. I don't know how to make my detail view responds to my master view. Also, in the template, the detailViewController has a id detailItem and a method setDetailItem. How are these two connected? I cannot see any connection between but setDetailItem is called when detailViewController.detailItem is being called. Thanks in advance.

• Confused about definition of a 'median' when constructing a kd-Tree

  - by user352636

  Hi there. Im trying to build a kd-tree for searching through a set of points, but am getting confused about the use of 'median' in the wikipedia article. For ease of use, the wikipedia article states the pseudo-code of kd-tree construction as: function kdtree (list of points pointList, int depth) { if pointList is empty return nil; else { // Select axis based on depth so that axis cycles through all valid values var int axis := depth mod k; // Sort point list and choose median as pivot element select median by axis from pointList; // Create node and construct subtrees var tree_node node; node.location := median; node.leftChild := kdtree(points in pointList before median, depth+1); node.rightChild := kdtree(points in pointList after median, depth+1); return node; } } I'm getting confused about the "select median..." line, simply because I'm not quite sure what is the 'right' way to apply a median here. As far as I know, the median of an odd-sized (sorted) list of numbers is the middle element (aka, for a list of 5 things, element number 3, or index 2 in a standard zero-based array), and the median of an even-sized array is the sum of the two 'middle' elements divided by two (aka, for a list of 6 things, the median is the sum of elements 3 and 4 - or 2 and 3, if zero-indexed - divided by 2.). However, surely that definition does not work here as we are working with a distinct set of points? How then does one choose the correct median for an even-sized list of numbers, especially for a length 2 list? I appreciate any and all help, thanks! -Stephen

• Capture data read from file into string stream Java

  - by halluc1nati0n

  I'm coming from a C++ background, so be kind on my n00bish queries... I'd like to read data from an input file and store it in a stringstream. I can accomplish this in an easy way in C++ using stringstreams. I'm a bit lost trying to do the same in Java. Following is a crude code/way I've developed where I'm storing the data read line-by-line in a string array. I need to use a string stream to capture my data into (rather than use a string array).. Any help? char dataCharArray[] = new char[2]; int marker=0; String inputLine; String temp_to_write_data[] = new String[100]; // Now, read from output_x into stringstream FileInputStream fstream = new FileInputStream("output_" + dataCharArray[0]); // Convert our input stream to a BufferedReader BufferedReader in = new BufferedReader (new InputStreamReader(fstream)); // Continue to read lines while there are still some left to read while ((inputLine = in.readLine()) != null ) { // Print file line to screen // System.out.println (inputLine); temp_to_write_data[marker] = inputLine; marker++; }

• Google Maps, marker info window won't show up ?

  - by user296516

  Hi guys, I have written this code that loops through an array of lat/long coordinates and places a marker at each of the coordinate. Everything forks fine, exempt the info window won't appear once the marker is clicked. var ExpTowerIcon = new GIcon(); ExpTowerIcon.image = "tower.png"; ExpTowerIcon.iconSize = new GSize(75, 75); ExpTowerIcon.iconAnchor = new GPoint(37, 65); ExpTowerIcon.infoWindowAnchor = new GPoint(37, 20); var marker=new Array(); for ( i=0 ; i < lat.length ; i++ ) { var MarkerPoint = new GLatLng(lat[i],long[i]); marker[i] = new GMarker(MarkerPoint,{icon:ExpTowerIcon}) map.addOverlay( marker[i] ); GEvent.addListener( marker[i] , 'click', function() { marker[i].openInfoWindowHtml('Hello!') ; }); var polyline = new GPolyline([ new GLatLng(lat[i],long[i]) , new GLatLng(lat[i+1],long[i+1]) ], "#ff0000", 5); map.addOverlay(polyline); } Any ideas?

• Fit <TD> height to page

  - by ssg

  Consider a table with three rows with heights 10, *, 10. I'd like the middle cell to be high enough to fit to the page vertically. Unfortunately "height:100%" doesn't work at table, tr, or td level, possibly due to standards. Even if it happens to work, I don't want 100%, I want 100% of clientHeight-20px :) I can always write script to calculate remaining clientHeight but I wonder if it can be achieved in HTML/CSS standards. NOTE: I'm using table just for layout, if there are other ways to lay them down in a better way I'm ok with those approaches too.

• Overriding events of excel sheet using VBA

  - by Rashmi Pandit

  Hi, I need to programmatically override the following events of a worksheet: BeforeDoubleClick SelectionChange BeforeRightClick I have been able to override the OnActivate event using the following code: sheet.OnSheetActivate = "MyOwn_Activate" Private Sub MyOwn_Activate() myForm.Show End Sub I have implemented BeforeDoubleClick on similar lines: sheet.OnDoubleClick = "My_BeforeDoubleClick" Private Sub My_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean) ... End Sub However, an 'argument not optional' error is thrown at run-time when user double clicks a cell on the sheet. Can someone please suggest how should I pass the paramters? In addition, I am not able to find event names for SelectionChange & BeforeRightClick. I tried: sheet.BeforeRightClick = "My_BeforeRightClick" sheet.SelectionChange = "My_SelectionChange" But, both the above lines do not work. Any help/ suggestion is greatly appreciated. Thanks :)

• PHP Treat String as Variable

  - by Ygam

  Hi guys. I have a piece of code here that does not work despite me using a $$ on it to treat the string as a variable: <? foreach (KOHANA::config('list.amenities_forms') as $k => $v) : ?> <div class="form"> <fieldset> <legend><?php echo $v ?></legend> <input type="checkbox" name="<?=$k?>flag" id="<?=$k?>flag"/> <label class="inline"><?=$v?></label> <label>Description</label> <textarea cols="50" rows="5" name="<?=$k?>[]"><?= empty($$k[0]) ?

• Enumerating a string

  - by JamesB

  I have a status which is stored as a string of a set length, either in a file or a database. I'm looking to enumerate the possible status' I have the following type to define the possible status' Type TStatus = (fsNormal = Ord('N'),fsEditedOnScreen = Ord('O'), fsMissing = Ord('M'),fsEstimated = Ord('E'),fsSuspect = Ord('s'), fsSuspectFromOnScreen = Ord('o'),fsSuspectMissing = Ord('m'), fsSuspectEstimated = Ord('e')); Firstly is this really a good idea? or should I have a seperate const array storing the char conversions? That would mean more than one place to update. Now convert a string to a status array I have the following, but how can I check if a char is valid without looping through the enumeration? Function StrToStatus(Value : String):TStatusArray; var i: Integer; begin if Trim(Value) = '' then begin SetLength(Result,0); Exit; end; SetLength(Result,Length(Value)); for i := 1 to Length(Value) do begin Result[i] := TStatus(Value[i]); // I don't think this line is safe. end; end; AFAIK this should be fine for converting back again. Function StatusToStr(Value : TStatusArray):String; var i: Integer; begin for i := 0 to Length(Value) - 1 do Result := Result + Chr(Ord(Value[i])) end; I'm using Delphi 2007

• Adding a date every few days

  - by Luke

  I have some code that generates fixtures, I am looking to add a fixture date to the code. $totalRounds = $teams - 1; $matchesPerRound = $teams / 2; $rounds = array(); for ($i = 0; $i < $totalRounds; $i++) { $rounds[$i] = array(); } for ($round = 0; $round < $totalRounds; $round++) { for ($match = 0; $match < $matchesPerRound; $match++) { $home = ($round + $match) % ($teams - 1); $away = ($teams - 1 - $match + $round) % ($teams - 1); // Last team stays in the same place while the others // rotate around it. if ($match == 0) { $away = $teams - 1; } $rounds[$round][$match] = "$user[$home]~$team[$home]@$user[$away]~$team[$away]"; } } $team is the amount of teams in the league. I want to add a variable for every 4 days, and for every round of fixtures generated, I want to add 4 days onto the previous round. For example, if today is 3rd may, i want 3rd may for first fixture, 7th may for second fixture, 11th may for third fixture. By fixture i mean round which includes a set of fixtures!

• How does void QTableWidget::setItemPrototype ( const QTableWidgetItem * item ) clones objects?

  - by chappar

  QTableWidget::setItemPrototype says following. "The table widget will use the item prototype clone function when it needs to create a new table item. For example when the user is editing in an empty cell. This is useful when you have a QTableWidgetItem subclass and want to make sure that QTableWidget creates instances of your subclass." How does this actually work as you can pass any of the QTableWidgetItem subclass pointer to setItemPrototype and at run time there is no way you can get the size of an object having just pointer to it?

• VB.net httpwebrequest For loop hangs every 10 or so iterations

  - by user574632

  Hello, I am trying to loop through an array and perform an httpwebrequest in each iteration. The code seems to work, however it pauses for a while (eg alot longer than the set timeout. Tried setting that to 100 to check and it still pauses) after every 10 or so iterations, then carries on working. Here is what i have so far: For i As Integer = 0 To numberOfProxies - 1 Try 'create request to a proxyJudge php page using proxy Dim request As HttpWebRequest = HttpWebRequest.Create("http://www.pr0.net/deny/azenv.php") request.Proxy = New Net.WebProxy(proxies(i)) 'select the current proxie from the proxies array request.Timeout = 10000 'set timeout Dim response As HttpWebResponse = request.GetResponse() Dim sr As StreamReader = New StreamReader(response.GetResponseStream()) Dim pageSourceCode As String = sr.ReadToEnd() 'check the downloaded source for certain phrases, each identifies a type of proxy 'HTTP_X_FORWARDED_FOR identifies a transparent proxy If pageSourceCode.Contains("HTTP_X_FORWARDED_FOR") Then 'delegate method for cross thread safe UpdateListbox(ListBox3, proxies(i)) ElseIf pageSourceCode.Contains("HTTP_VIA") Then UpdateListbox(ListBox2, proxies(i)) Else UpdateListbox(ListBox1, proxies(i)) End If Catch ex As Exception 'MessageBox.Show(ex.ToString) used in testing UpdateListbox(ListBox4, proxies(i)) End Try completedProxyCheck += 1 lblTotalProxiesChecked.CustomInvoke(Sub(l) l.Text = completedProxyCheck) Next I have searched all over this site and via google, and most responses to this type of question say the response must be closed. I have tried a using block, eg: Using response As HttpWebResponse = request.GetResponse() Using sr As StreamReader = New StreamReader(response.GetResponseStream()) Dim pageSourceCode As String = sr.ReadToEnd() 'check the downloaded source for certain phrases, each identifies a type of proxy 'HTTP_X_FORWARDED_FOR identifies a transparent proxy If pageSourceCode.Contains("HTTP_X_FORWARDED_FOR") Then 'delegate method for cross thread safe UpdateListbox(ListBox3, proxies(i)) ElseIf pageSourceCode.Contains("HTTP_VIA") Then UpdateListbox(ListBox2, proxies(i)) Else UpdateListbox(ListBox1, proxies(i)) End If End Using End Using And it makes no difference (though i may have implemented it wrong) As you can tell im very new to VB or any OOP so its probably a simple problem but i cant work it out. Any suggestions or just tips on how to diagnose these types of problems would be really appreciated.

• How do I read text from a serial port?

  - by user2164

  I am trying to read data off of a Windows serial port through Java. I have the javax.comm libraries and am able to get some data but not correct data. When I read the port into a byte array and convert it to text I get a series of characters but no real text string. I have tried to specify the byte array as being both "UTF-8" and "US-ASCII". Does anyone know how to get real text out of this? Here is my code: while (inputStream.available() > 0) { int numBytes = inputStream.read(readBuffer); System.out.println("Reading from " + portId.getName() + ": "); System.out.println("Read " + numBytes + " bytes"); } System.out.println(new String(readBuffer)); System.out.println(new String(readBuffer, "UTF-8")); System.out.println(new String(readBuffer, "US-ASCII")); the output of the first three lines will not let me copy and paste (I assume because they are not normal characters). Here is the output of the Hex: 78786000e67e9e60061e8606781e66e0869e98e086f89898861878809e1e9880 I am reading from a Hollux GPS device which does output in string format. I know this for sure because I did it through C#. The settings that I am using for communication which I know are right from the work in the C# app are: Baud Rate: 9600 Databits: 8 Stop bit: 1 parity: none

• Putting a C++ Vector as a Member in a Class that Uses a Memory Pool

  - by Deep-B

  Hey, I've been writing a multi-threaded DLL for database access using ADO/ODBC for use with a legacy application. I need to keep multiple database connections for each thread, so I've put the ADO objects for each connection in an object and thinking of keeping an array of them inside a custom threadInfo object. Obviously a vector would serve better here - I need to delete/rearrange objects on the go and a vector would simplify that. Problem is, I'm allocating a heap for each thread to avoid heap contention and stuff and allocating all my memory from there. So my question is: how do I make the vector allocate from the thread-specific heap? (Or would it know internally to allocate memory from the same heap as its wrapper class - sounds unlikely, but I'm not a C++ guy) I've googled a bit and it looks like I might need to write an allocator or something - which looks like so much of work I don't want. Is there any other way? I've heard vector uses placement-new for all its stuff inside, so can overloading operator new be worked into it? My scant knowledge of the insides of C++ doesn't help, seeing as I'm mainly a C programmer (even that - relatively). It's very possible I'm missing something elementary somewhere. If nothing easier comes up - I might just go and do the array thing, but hopefully it won't come to that. I'm using MS-VC++ 6.0 (hey, it's rude to laugh! :-P ). Any/all help will be much appreciated.

• C pointers and addresses

  - by yCalleecharan

  Hi, I always thought that *&p = p = &*p in C. I tried this code: #include <stdio.h> #include <stdlib.h> char a[] = "programming"; char *ap = &a[4]; int main(void) { printf("%x %x %x\n", ap, &*(ap), *&(ap)); /* line 13 */ printf("%x %x %x\n\n", ap+1, &*(ap+1), *&(ap+1)); /* line 14 */ } The first printf line (line 13) gives me the addresses: 40b0a8 40b0a8 40b0a8 which are the same as expected. But when I added the second printf line, Borland complains: "first.c": E2027 Must take address of a memory location in function main at line 14 I was expecting to get: 40b0a9 40b0a9 40b0a9. It seems that the expression *&(ap+1) on line 14 is the culprit here. I thought all three pointer expressions on line 14 are equivalent. Why am I thinking wrong? A second related question: The line char *ap = a; points to the first element of array a. I used char *ap = &a[4]; to point to the 5th element of array a. Is the expression char *ap = a; same as the expression char *ap = &a[0]; Is the last expression only more verbose than the previous one? Thanks a lot...

• Getting the height of text to know fill height as in TCPDF

  - by sami

  I'm trying to go through the code of TCPDF to understand how it calculates the height of the text to be rendered, but it's too much for me to handle without asking. What I want to know: in the PDF from example 5 http://www.tcpdf.org/examples/example_005.pdf it gives the cell a yellow background. I'm guessing that at the basic level, it first draws a box with this fill color, then adds the text, so what method is it calling to get the height of the text to know the height of the box to fill? Anyone knows how to trace this, because doing it by hand and looking through the code isn't working at all for me.

  To all excuse my ignorance, but im new to MDX below is the query im trying to run SELECT NON EMPTY { [Measures].[Task Burn Down] } ON COLUMNS, NON EMPTY { ([Calendar].[Date].[Date].ALLMEMBERS * [Priority].[Priority Code].[Priority Code].ALLMEMBERS ) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM ( SELECT ( { Filter([Calendar].[Date].AllMembers, [Calendar].[Date].CurrentMember <= [Sprint].[Sprint].CurrentMember.Properties("Stop Date")) } ) ON COLUMNS FROM ( SELECT ( { [Sprint].[Sprint].AllMembers } ) ON COLUMNS FROM ( SELECT ( { [Team].[Team].AllMembers } ) ON COLUMNS FROM [Backlog2] ) ) ) WHERE ( [Team].[Team].&[27], [Sprint].[Sprint].&[9] ) CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS When I run this I expect to get 1 value for [Measures].[Task Burn Down] for each day of the month. But I only want one month. My Sprint dimension has a stop date and I do not want to return any values after the stop date. What am I doing wrong?
