• Coordinate system problem with the grid control

  - by Jason94

  In my WPF application im trying to visualize some temperature data. I have a list of temperatures for the 7 past days and want to make a point to point line diagram. My problem is with the different koordinatesystems and adjusting data to the grid. XAML: <Grid Height="167" HorizontalAlignment="Left" Margin="6,6,0,0" Name="grid1" VerticalAlignment="Bottom" Width="455" /> C# (draft): http://pastebin.com/6UWkMFj1 scale is a global variable that changes with a slider (1-10). How to i correct my application so the line always is centered? As it is now it starts out centeded but if i crank up the slider to 3-4 the line goes up and above the applicationwindow. I also would like to use the full height of the grid window not just a small piece like images below: http://img32.imageshack.us/i/002wtvu.jpg/ http://img691.imageshack.us/i/001tqco.jpg/ As you can see i have worked out my data so day 1 with temperature 62 F is lower then day 2 with temperature of 76 F but i have scaling issues and placementissues... could somebody straighten out my math? :-)

• C++ class with char pointers returning garbage

  - by JMP

  I created a class "Entry" to handle Dictionary entries, but in my main(), I create the Entry() and try to cout the char typed public members, but I get garbage. When I look at the Watch list in debugger, I see the values being set, but as soon as I access the values, there is garbage. Can anyone elaborate on what I might be missing? #include <iostream> using namespace std; class Entry { public: Entry(const char *line); char *Word; char *Definition; }; Entry::Entry(const char *line) { char tmp[100]; strcpy(tmp, line); Word = strtok(tmp, ",") + '\0'; Definition = strtok(0,",") + '\0'; } int main() { Entry *e = new Entry("drink,What you need after a long day's work"); cout << "Word: " << e->Word << endl; cout << "Def: " << e->Definition << endl; cout << endl; delete e; e = 0; return 0; }

• Limit CPU usage of a process

  - by jb

  I have a service running which periodically checks a folder for a file and then processes it. (Reads it, extracts the data, stores it in sql) So I ran it on a test box and it took a little longer thaan expected. The file had 1.6 million rows, and it was still running after 6 hours (then I went home). The problem is the box it is running on is now absolutely crippled - remote desktop was timing out so I cant even get on it to stop the process, or attach a debugger to see how far through etc. It's solidly using 90%+ CPU, and all other running services or apps are suffering. The code is (from memory, may not compile): List<ItemDTO> items = new List<ItemDTO>(); using (StreamReader sr = fileInfo.OpenText()) { while (!sr.EndOfFile) { string line = sr.ReadLine() try { string s = line.Substring(0,8); double y = Double.Parse(line.Substring(8,7)); //If the item isnt already in the collection, add it. if (items.Find(delegate(ItemDTO i) { return (i.Item == s); }) == null) items.Add(new ItemDTO(s,y)); } catch { /*Crash*/ } } return items; } - So I am working on improving the code (any tips appreciated). But it still could be a slow affair, which is fine, I've no problems with it taking a long time as long as its not killing my server. So what I want from you fine people is: 1) Is my code hideously un-optimized? 2) Can I limit the amount of CPU my code block may use? Cheers all

• PHP Form - Edit & Delete via Text File Db

  - by Jax

  hi, I pieced together the script below from various tutorials, examples, etc... Right now the script currently: Saves Id, Name, Url with a "|" delimiter to a text file Db like: 1|John|http://www.john.com| 2|Mark|http://www.mark.com| 3|Fred|http://www.fred.com| But I'm having a hard time trying to make the "UPDATE" and "DELETE" buttons work. Can someone please post code which will: let me update/save any changed data for that row (for UPDATE button) let me delete that row (for DELETE button) PLEASE copy n paste the code below and try for yourself. I would like to keep the output format of the script below too. thanks D- $file = "data.txt"; $name = $_POST['name']; $url = $_POST['url']; $data = file('data.txt'); $i = 1; foreach ($data as $line) { $line = explode('|', $line); $i++; } if (isset($_POST['submits'])) { $fp = fopen($file, "a+"); fwrite($fp, $i."|".$name."|".$url."|\n"); fclose($fp); } ?

• "Invalid use of Null" when using Str() with a Null Recordset field, but Str(Null) works fine

  - by Mike Spross

  I'm banging my head against the wall on this one. I was looking at some old database reporting code written in VB6 and case across this line (the code is moving data from a "source" database into a reporting database): rsTarget!VehYear = Trim(Str(rsSource!VehYear)) When rsSource!VehYear is Null, the above line generates an "Invalid use of Null" run-time error. If I break on the above line and type the following in the Immediate pane: ?rsSource!VehYear It outputs Null. Fine, that makes sense. Next, I try to reproduce the error: ?Str(rsSource!VehYear) I get an "Invalid use of Null" error. However, if I type the following into the Immediate window: ?Str(Null) I don't get an error. It simply outputs Null. If I repeat the same experiment with Trim() instead of Str(), everything works fine. ?Trim(rsSource!VehYear) returns Null, as does ?Trim(Null). No run-time errors. So, my question is, how can Str(rsSource!VehYear) possibly throw an "Invalid use of Null" error when Str(Null) does not, when I know that rsSource!VehYear is equal to Null?

• Detecting when a cell's detail-disclosure button has been clicked (when using a custom cell XIB)

  - by Gloria

  1 if (cell == nil) 2 { 3 [[NSBundle mainBundle] loadNibNamed:@"TVCell" owner:self options:nil]; 4 cell = tvCell; 5 self.tvCell = nil; 6 } There's some code from an Apple example of using your own "custom cell XIB" to create cells in a UITableView. It appears to work... but I think I would do better to actually UNDERSTAND what is being done there. Why isn't line #3 assigning the value TO something? cell = [[NSBundle mainBundle] loadNibNamed:@"TVCell" owner:self options:nil]; (In fact, cell and tvCell aren't being used at all.) Why is line #4 assigning using tvCell when nothing has been put it in at all, yet? Why is line #5 nulling out the tvCell that I need? Why is "@property (nonatomic, assign) IBOutlet UITableViewCell *tvCell;" using assign, not retain? About the only thing I can't get working correctly is when I put a disclosure-button on my custom cell XIB. Is there a way for me to detect when the user has clicked on it? (Hopefully, without using 100s of TAGs.)

• Echoing users by group name in PHP

  - by BobSapp

  What I want to do is click a name of a group(every group what I create other than poweruser and admin groups) and that will echo all of the users in that group from the database. I have figured out the code so far but now my problem is how will I print it all out when clicking the name of the group? My code so far is: <h3>Groups</h3> <?php include('db.php'); if (isset($_GET["groupID"])) { $sql="SELECT `group`.*, `user`.* FROM `user` inner join `group` on group.groupID=user.groupID where group.groupID= " . mysql_real_escape_string($_GET["groupID"]) ; } else { $sql="SELECT * FROM `group` WHERE groupName <> 'admin' AND groupName <> 'poweruser'" ; } $result=mysql_query($sql,$connection); while($line=mysql_fetch_array($result)){ echo "<a href='index.php?page=groups&group=".$line['groupID']."'>".$line['groupName'].'</a><br />'; } mysql_free_result($result); mysql_close($connection); ?>

• Trouble with StreamReader

  - by John

  Alright so here is what I have so far, List<string> lines = new List<string>(); using (StreamReader r = new StreamReader(f)) { string line; while ((line = r.ReadLine()) != null) { lines.Add(line); } } foreach (string s in lines) { NetworkStream stream = irc.GetStream(); writer.WriteLine(USER); writer.Flush(); writer.WriteLine("NICK " + NICK); writer.Flush(); writer.WriteLine("JOIN " + s); writer.Flush(); string trimmedString = string.Empty; CHANNEL = s; } Unfortunately when my IRC dummy enters a room with a password set it writes out the password, if I make it change channel with a command such as #lol test test being the password, since CHANNEL = s; it writes out the password with the command writer.WriteLine("PRIVMSG " + CHANNEL + " :" + "Hello"); That is the only way to write out to IRC so is there a way for the "CHANNEL" to only be the start of the text and just #lol so it doesn't write out the password? I hope you understand my problem.

• Faster Insertion of Records into a Table with SQLAlchemy

  - by Kyle Brandt

  I am parsing a log and inserting it into either MySQL or SQLite using SQLAlchemy and Python. Right now I open a connection to the DB, and as I loop over each line, I insert it after it is parsed (This is just one big table right now, not very experienced with SQL). I then close the connection when the loop is done. The summarized code is: log_table = schema.Table('log_table', metadata, schema.Column('id', types.Integer, primary_key=True), schema.Column('time', types.DateTime), schema.Column('ip', types.String(length=15)) .... engine = create_engine(...) metadata.bind = engine connection = engine.connect() .... for line in file_to_parse: m = line_regex.match(line) if m: fields = m.groupdict() pythonified = pythoninfy_log(fields) #Turn them into ints, datatimes, etc if use_sql: ins = log_table.insert(values=pythonified) connection.execute(ins) parsed += 1 My two questions are: Is there a way to speed up the inserts within this basic framework? Maybe have a Queue of inserts and some insertion threads, some sort of bulk inserts, etc? When I used MySQL, for about ~1.2 million records the insert time was 15 minutes. With SQLite, the insert time was a little over an hour. Does that time difference between the db engines seem about right, or does it mean I am doing something very wrong?

• C Programming - Passing a pointer to array

  - by Pedro

  How do I pass a pointer value to an array of the struct; For example, on a txt I have this: John Doe;[email protected];214425532; My code: typedef struct Person{ char name[100]; char email[100]; int phone; }PERSON; int main(){ PERSON persons[100]; FILE *fp; char *ap_name; char *ap_email; char *ap_phone; char line[100]; fp=("text.txt","r"); if(fp==NULL){ exit(1); } else{ fgets(line,100,fp); ap_name=strtok(line,";"); ap_email=strtok(NULL,";"); ap_phone=strtok(NULL,";"); } return 0; } My question is how can I pass the value of ap_name, ap_email, ap_phone to the struct? And, do I need to use all of these pointers?

• php script randomly hangs up

  - by sergdev

  I install php 5 (more precisely 5.3.1) as apache module. After this one of my application becomes randomly hang up on mysql_connect - sometimes works, sometimes no, sometimes reload of page helps. How can this be fixed? I use Windows Vista, Apache/2.2.14 (Win32) PHP/5.3.1 with php module, MySql 5.0.67-community-nt. After a minute I obtain the error message: Fatal error: Maximum execution time of 60 seconds exceeded in path\to\mysqlcon.php on line 9 I run MySql locally and heavy load could not be a reason: SHOW PROCESSLIST shows about 3 process SHOW VARIABLES LIKE 'MAX_CONNECTIONS' is 100. UPDATE: At first I thought that this is connected with mysql_connect. But now I can't say for certain. More difficult thing is when I insert the line to debug: $fh = fopen("E://_debugLog", 'a'); fwrite($fh, __FILE__ . " : " . __LINE__ . "\n"); fclose($fh); script start working near that location as a rule.

• java: how to parse html-like xml

  - by Yang

  I have an html-like xml, basically it is html. I need to get the elements in each . Each element looks like this: <line tid="744476117"> <attr>1414</attr> <attr>31</attr><attr class="thread_title">title1</attr><attr>author1</attr><attr>date1</attr></line> My code is as below, it does recognize that there are 50 in the file, but it gives me NULLPointException when parsing NodeList fstNmElmntLst = fstElmnt.getElementsByTagName("attr"); Any idea why this is happening? The same code has been used for other applications without problems. DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); InputSource is = new InputSource(); is.setCharacterStream(new StringReader(cleanxml)); Document doc = db.parse(is); doc.getDocumentElement().normalize(); System.out.println("Root element " + doc.getDocumentElement().getNodeName()); NodeList nodeLst = doc.getElementsByTagName("line"); for (int s = 0; s < nodeLst.getLength(); s++) { System.out.println(nodeLst.getLength()); Node fstNode = nodeLst.item(s); if (fstNode.getNodeType() == Node.ELEMENT_NODE) { Element fstElmnt = (Element) fstNode; NodeList fstNmElmntLst = fstElmnt.getElementsByTagName("attr"); Element fstNmElmnt = (Element) fstNmElmntLst.item(0); NodeList fstNm = fstNmElmnt.getChildNodes(); System.out.println("attr : " + ((Node) fstNm.item(0)).getNodeValue()); } }

• how to achieve functionality of #def of c in PHP

  - by Sabya

  Well, I don't know if thats what I want. But here is my problem: In case of some error I am logging the FILE, CLASS, FUNCTION and LINE in a file. For that I am doing something like: myLog('['. __FILE__ . ']' . '[' . __CLASS__ . ']' . '[' . __FUNCTION__ . ']' . '[' . __LINE__ . ']'); The problem is everywhere I've to repeat that code in the parameter. and If I want to change the format, I've to change everywhere. How can I have something like: myLog(LOG_MSG_FORMAT); With PHP define it is not possible since it will give my the LINE number of the place where that definition is, not where the definition is getting used. Any solution to this is welcome. I am not bitchy about having C like functionality of #def.

• A question on webpage representation in Java

  - by Gemma

  Hello there. I've followed a tutorial and came up with the following method to read the webpage content into a CharSequence public static CharSequence getURLContent(URL url) throws IOException { URLConnection conn = url.openConnection(); String encoding = conn.getContentEncoding(); if (encoding == null) { encoding = "ISO-8859-1"; } BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream(),encoding)); StringBuilder sb = new StringBuilder(16384); try { String line; while ((line = br.readLine()) != null) { sb.append(line); sb.append('\n'); } } finally { br.close(); } return sb; } It will return a representation of the webpage specified by the url. However,this representation is hugely different from what I use "view page source" in my Firefox,and since I need to scrape data from the original webpage(some data segement in the original "view page source" file),it will always fail to find required text on this Java representation. Did I go wrong somewhere?I need your advice guys,thanks a lot for helping!

• Reading lines of data from text files using java

  - by razshan

  I have a text file with x amount of lines. each line holds a integer number. When the user clicks a button, an action is performed via actionlistener where it should list all the values as displayed on the text file. However, right now I have linenum set to 10 implying I already told the code that just work with 10 lines of the text file. So, if my text file has only 3 rows/lines of data...it will list those lines and for rest of the other 7 lines, it will spit out "null". I recall there is a way to use ellipsis to let the program know that you don't know the exact value but at the end it calculates it based on the given information. Where my given information will the number of lines with numbers(data). Below is part of the code. private class thehandler implements ActionListener{ public void actionPerformed(ActionEvent event){ BufferedReader inputFile=null; try { FileReader freader =new FileReader("Data.txt"); inputFile = new BufferedReader(freader); String MAP = ""; int linenum=10; while(linenum > 0) { linenum=linenum-1; MAP = inputFile.readLine();//read the next line until the specfic line is found System.out.println(MAP); } } catch( Exception y ) { y.printStackTrace(); } }}

• Static Analyzer says I have a leak....why?

  - by Walter

  I think this code should be fine but Static Analyzer doesn't like it. I can't figure out why and was hoping that someone could help me understand. The code works fine, the analyzer result just bugs me. Coin *tempCoin = [[Coin alloc] initalize]; self.myCoin = tempCoin; [tempCoin release]; Coin is a generic NSObject and it has an initalize method. myCoin is a property of the current view and is of type Coin. I assume it is telling me I am leaking tempCoin. In my view's .h I have set myCoin as a property with nonatomic,retain. I've tried to autorelease the code as well as this normal release but Static Analyzer continues to say: 1. Method returns an Objective-C object with a +1 retain count (owning reference) 2. Object allocated on line 97 is no longer referenced after this point and has a retain count of +1 (object leaked) Line 97 is the first line that I show.

• How do I get rid of this "(" using regex?

  - by Solignis

  Hi there, I was moving along on a regex expression and I have hit a road block I can't seem to get around. I am trying to get rid of "(" in the middle of a line of text using regex, there were 2 but I figured out how to get the one on the end of the line. its the one in the middle I can hack out. Here is the snippet I am searching for in the config file. I put 2 examples. guestOSAltName = "Ubuntu Linux (64-bit)" guestOSAltName = "Microsoft Windows 2000 Professional" Here is the snippet I am working on. if ($vmx_file =~ m/^\bguestOSAltName\b\s+\S\s+\W(?<GUEST_OS> .+[^")])\W/xm) { $virtual_machines{$vm}{"OS"} = "$+{GUEST_OS}"; } else { $virtual_machines{$vm}{"OS"} = "N/A"; } I am thinking the problem is I cannot make a match to "(" because the expression before that is to ".+" so that it matches everything in the line of text, be it alphanumeric or whitespace or even symbols like hypens. Any ideas how I can get this to work? This is what I am getting for an output from a hash dump. $VAR1 = { 'NS02' => { 'ID' => '144', 'Version' => '7', 'OS' => 'Ubuntu Linux (64-bit', 'VMX' => '/vmfs/volumes/datastore2/NS02/NS02.vmx', 'Architecture' => '64-bit' },

• How do I efficiently parse a CSV file in Perl?

  - by Mike

  I'm working on a project that involves parsing a large csv formatted file in Perl and am looking to make things more efficient. My approach has been to split() the file by lines first, and then split() each line again by commas to get the fields. But this suboptimal since at least two passes on the data are required. (once to split by lines, then once again for each line). This is a very large file, so cutting processing in half would be a significant improvement to the entire application. My question is, what is the most time efficient means of parsing a large CSV file using only built in tools? note: Each line has a varying number of tokens, so we can't just ignore lines and split by commas only. Also we can assume fields will contain only alphanumeric ascii data (no special characters or other tricks). Also, i don't want to get into parallel processing, although it might work effectively. edit It can only involve built-in tools that ship with Perl 5.8. For bureaucratic reasons, I cannot use any third party modules (even if hosted on cpan) another edit Let's assume that our solution is only allowed to deal with the file data once it is entirely loaded into memory. yet another edit I just grasped how stupid this question is. Sorry for wasting your time. Voting to close.

• append text to lines in a CSV file

  - by MichaelMcCabe

  This question seems to have been asked a million times around the web, but I cannot find an answer which will work for me. Basically, I have a CSV file which has a number of columns (say two). The program goes through each row in the CSV file, taking the first column value, then asks the user for the value to be placed in the second column. This is done on a handheld running Windows 6. I am developing using C#. It seems a simple thing to do. But I cant seem to add text to a line. I cant use OleDb, as System.Data.Oledb isnt in the .Net version I am using. I could use another CSV file, and when they complete each line, it writes it to another CSV file. But the problems with that are - The file thats produced at the end needs to contain EVERY line (so what if they pull the batterys out half way). And what if they go back, to continue doing this another time, how will the program know where to start back from.

• Emacs hide/show support for C++ triple-slash Doxygen markup?

  - by jsyjr

  I use Doxygen's triple-slash syntax to markup my C++ code. There are two important cases which arise: 1) block markup comments which are the sole element on the line and may or may not begin flush left; e.g. class foo /// A one sentence brief description of foo. The elaboration can /// continue on for many lines. { ... }; void foo::bar /// A one sentence brief description of bar. The elaboration can /// continue on for many lines. () const { ... } 2) trailing markup comments which always follow some number of C++ tokens earlier on the first line but may still spill over onto subsequent lines; e.g. class foo { int _var1; ///< A brief description of _var1. int _var2; ///< A brief description of _var2 ///< requiring additional lines. } void foo::bar ( int arg1 ///< A brief description of arg1. , int arg2 ///< A brief description of arg2 ///< requiring additional lines. ) const { ... } I wonder what hide/show support exists to deal with these conventions. The most important cases are the block markup comments. Ideally I would like to be able to eliminate these altogether, meaning that I would prefer not to waste a line simply to indicate presence of a folded block markup comment. Instead I would like a fringe marker, a la http://www.emacswiki.org/emacs/hideshowvis.el /john

• Storing strings from a text file/scanner. Array or built-in?

  - by Flowdorio

  This code snippet is to to read a text file, turn the lines into objects through a different public (non changeable) class(externalClass). The external class does nothing but turn strings (lines from the .txt through nextLine) into objects, and is fully functional. The scanner(scanner3) is assigned to the text file. while (scanner3.hasNext()) { externalClass convertedlines = new externalClass(scanner3.nextLine()); I'm not new to programming, but as I'm new to java, I do not know if this requires me to create an array, or if the returned objects are sorted in some other way. i.e is the "importedlines" getting overwritten with each run of the loop(and I need to introduce an array into the loop), or are the objects stored in some way? The question may seem strange, but with the program I am making it would be harder (but definitely not impossible) if I used an array. Any help would be appreciated. As requested, externalClass: public class exernalClass { private String line; externalClass(String inLine){ line = inLine; } public String giveLine() { return line; } }
