  • Need help in displaying data insider marquee

    - by user59637
    Hi all, I want to display news inside the marquee markup in my banking application but its not happening.Please somebody help me what is the error in my code.Here is my code: <marquee bgcolor="silver" direction="left" id="marq1" runat="server" behavior="scroll" scrolldelay="80" style="height: 19px" width="565"> <% String se = Session["countnews"].ToString(); for (int i = 0; i < int.Parse("" +se); i++) { %> <strong><%Response.Write("&nbsp;&nbsp;" + Session["news"+i] + "&nbsp;&nbsp;"); %></strong> <% } %> </marquee> public class News { DataSet ds = new DataSet("Bank"); SqlConnection conn; String check; SqlDataAdapter sda; int i; public string News_Name; public int Count_News; public int newsticker() { conn = new SqlConnection(ConfigurationManager.ConnectionStrings["BankingTransaction"].ConnectionString.ToString()); check = "Select NewsTitle from News where NewsStatus = 'A'"; sda = new SqlDataAdapter(check, conn); sda.Fill(ds, "News"); if (ds.Tables[0].Rows.Count > 0) { for (i = 0; i < ds.Tables[0].Rows.Count; i++) { News_Name =i+ ds.Tables[0].Rows[i].ItemArray[0].ToString(); } Count_News = ds.Tables[0].Rows.Count; } else { News_Name =0+ "Welcome to WestSide Bank Online Web site!"; Count_News = 1; } return int.Parse(Count_News.ToString()); } protected void Page_Load(object sender, EventArgs e) { News obj = new News(); try { obj.newsticker(); Session["news"] = obj.News_Name.ToString(); Session["countnews"] = obj.Count_News.ToString(); } catch (SqlException ex) { Response.Write("Error in login" + ex.Message); Response.Redirect("Default.aspx"); } finally { obj = null; } }

  • Memory efficient int-int dict in Python

    - by Bolo
    Hi, I need a memory efficient int-int dict in Python that would support the following operations in O(log n) time: d[k] = v # replace if present v = d[k] # None or a negative number if not present I need to hold ~250M pairs, so it really has to be tight. Do you happen to know a suitable implementation (Python 2.7)? EDIT Removed impossible requirement and other nonsense. Thanks, Craig and Kylotan! To rephrase. Here's a trivial int-int dictionary with 1M pairs: >>> import random, sys >>> from guppy import hpy >>> h = hpy() >>> h.setrelheap() >>> d = {} >>> for _ in xrange(1000000): ... d[random.randint(0, sys.maxint)] = random.randint(0, sys.maxint) ... >>> h.heap() Partition of a set of 1999530 objects. Total size = 49161112 bytes. Index Count % Size % Cumulative % Kind (class / dict of class) 0 1 0 25165960 51 25165960 51 dict (no owner) 1 1999521 100 23994252 49 49160212 100 int On average, a pair of integers uses 49 bytes. Here's an array of 2M integers: >>> import array, random, sys >>> from guppy import hpy >>> h = hpy() >>> h.setrelheap() >>> a = array.array('i') >>> for _ in xrange(2000000): ... a.append(random.randint(0, sys.maxint)) ... >>> h.heap() Partition of a set of 14 objects. Total size = 8001108 bytes. Index Count % Size % Cumulative % Kind (class / dict of class) 0 1 7 8000028 100 8000028 100 array.array On average, a pair of integers uses 8 bytes. I accept that 8 bytes/pair in a dictionary is rather hard to achieve in general. Rephrased question: is there a memory-efficient implementation of int-int dictionary that uses considerably less than 49 bytes/pair?

  • WPF: Editable ComboBox; how to make search/auto-fill functionality case sensitive?

    - by unforgiven3
    Say I have a ComboBox, like so: <ComboBox IsEditable="True" Height="30"> <ComboBoxItem>robot</ComboBoxItem> <ComboBoxItem>Robot</ComboBoxItem> </ComboBox> If a user comes along and starts by typing a lower-case 'r' into that ComboBox when it is empty, the ComboBox predictably auto-fills itself with the word 'robot'. Great. Now the same user comes along and starts typing an upper-case 'R' into that ComboBox when it is again empty. Unpredictable, the ComboBox auto-fills itself with the lower-case word 'robot'. Not great. I desperately want it to auto-fill itself with 'Robot', but WPF does not seem to want to smile down upon me. No matter what you do (CAPS lock, shift+key), the ComboBox will always auto-fill with the lower case 'robot', provided that the lower case 'robot' precedes the upper case 'Robot' in the ComboBox's items collection. Is there any way to prevent this? This behavior is maddening and makes for an absolutely abysmal user experience.

  • Batch faulting in a to-many relationship for a collection of objects

    - by indragie
    Scenario: Let's say I have an entity called Author that has a to-many relationship called books to the Book entity (inverse relationship author). If I have an existing collection of Author objects, I want to fault in the books relationship for all of them in a single fetch request. Code This is what I've tried so far: NSArray *authors = ... // array of `Author` objects NSFetchRequest *fetchRequest = [NSFetchRequest fetchRequestWithEntityName:@"Book"]; fetchRequest.returnsObjectsAsFaults = NO; fetchRequest.predicate = [NSPredicate predicateWithFormat:@"author IN %@", authors]; Executing this fetch request does not result in the books relationship of the objects in the authors array being faulted in (inspected via logging). I've also tried doing the fetch request the other way around: NSArray *authors = ... // array of `Author` objects NSFetchRequest *fetchRequest = [NSFetchRequest fetchRequestWithEntityName:@"Author"]; fetchRequest.returnsObjectsAsFaults = NO; fetchRequest.predicate = [NSPredicate predicateWithFormat:@"SELF IN %@", authors]; fetchRequest.relationshipKeypathsForPrefetching = @[@"books"]; This doesn't fire the faults either. What's the appropriate way of going about doing this?

  • TStringList, Dynamic Array or Linked List in Delphi?

    - by lkessler
    I have a choice. I have an array of ordered strings that I need to store and access. It looks like I can choose between using: A TStringList A Dynamic Array of strings, and A Linked List of strings In what circumstances is each of these better than the others? Which is best for small lists (under 10 items)? Which is best for large lists (over 1000 items)? Which is best for huge lists (over 1,000,000 items)? Which is best tor minimize memory use? Which is best to minimize loading and/or access time? For reference, I am using Delphi 2009.

  • How can I query Google Spreadsheets API with a string value?

    - by ColinM
    I am using Zend_Gdata_SpreadsheetsListQuery. In PHP my query is: "confirmation=$confirmation" The problem is that $confirmation = 'AB-CD-EFG-012345'; Apparently the hyphens are causing problems with the query and the exception thrown is: Uncaught exception 'Zend_Gdata_App_HttpException' with message 'Expected response code 200, got 400 Parse error: Invalid token encountered' How can I quote or escape the value to not cause parse errors? Single quotes cause the same error, double quotes don't throw errors but there are no results to match.

  • In Zabbix how to separate data of the same type but from different sources?

    - by Jader Dias
    I have a machine that receives data from multiple sources. This machine forwards the data to the Zabbix Trapper. I want to be able to view this data separately. One way of doing that is to send data from each source with a different fake hostname. But this is not ideal. I can receive this data in more than one host. I would like to be able to see data from source 1 on host A separately from source 2 on host A and from source 1 in host B. Also posted on: http://www.zabbix.com/forum/showthread.php?t=16503

  • Row selection based on subtable data in MySQL

    - by Felthragar
    I've been struggling with this selection for a while now, I've been searching around StackOverflow and tried a bunch of stuff but nothing that helps me with my particular issue. Maybe I'm just missing something obvious. I have two tables: Measurements, MeasurementFlags "Measurements" contain measurements from a device, and each measurement can have properties/attributes attached to them (commonly known as "flags") to signify that the measurement in question is special in some way or another (for instance, one flag may signify a test or calibration measurement). Note: One record per flag! Right, so a record from the "Measurements" table can theoreticly have an unlimited amount of MeasurementFlags attached to it, or it can have none. Now, I need to select records from "Measurements", that have an attached "MeasurementFlag" valued "X", but it must also NOT have a flag valued "Y" attached to it. We're talking about a fairly large database with hundreds of millions of rows, which is why I'm trying to keep all of this logic within one query. Splitting it up would create too many queries, however if it's not possible to do in one query I guess I don't have a choise. Thanks in advance.

  • PL/SQL profiler missing data

    - by user289429
    We are using pl/sql profiler to collect metrics. We noticed that on one of the environment the plsql_profiler_runs table is populated with the total execution time but the finer details that gets collected in the table plsql_profiler_data is missing. Any idea why this would be happening? We do use dbms_profiler.flush_data() before stopping the profiler and have seen this work fine in another environment.

  • Processing command-line arguments in prefix notation in Python

    - by ejm
    I'm trying to parse a command-line in Python which looks like the following: $ ./command -o option1 arg1 -o option2 arg2 arg3 In other words, the command takes an unlimited number of arguments, and each argument may optionally be preceded with an -o option, which relates specifically to that argument. I think this is called a "prefix notation". In the Bourne shell I would do something like the following: while test -n "$1" do if test "$1" = '-o' then option="$2" shift 2 fi # Work with $1 (the argument) and $option (the option) # ... shift done Looking around at the Bash tutorials, etc. this seems to be the accepted idiom, so I'm guessing Bash is optimized to work with command-line arguments this way. Trying to implement this pattern in Python, my first guess was to use pop(), as this is basically a stack operation. But I'm guessing this won't work as well on Python because the list of arguments in sys.argv is in the wrong order and would have to be processed like a queue (i.e. pop from the left). I've read that lists are not optimized for use as queues in Python. So, my ideas are: convert argv to a collections.deque and use popleft(), reverse argv using reverse() and use pop(), or maybe just work with the int list indices themselves. Does anyone know of a better way to do this, otherwise which of my ideas would be best-practise in Python?

  • SQL to CodeIgniter Array Missing Data Issue

    - by SamD
    $query = $this->db->query("SELECT t1.numberofbets, t1.profit, t2.seven_profit, t3.28profit, user.user_id, username, password, email, balance, user.date_added, activation_code, activated FROM user LEFT JOIN (SELECT user_id, SUM(amount_won) AS profit, count(tip_id) AS numberofbets FROM tip GROUP BY user_id) as t1 ON user.user_id = t1.user_id LEFT JOIN (SELECT user_id, SUM(amount_won) AS seven_profit FROM tip WHERE date_settled > '$seven_daystime' GROUP BY user_id) as t2 ON user.user_id = t2.user_id LEFT JOIN (SELECT user_id, SUM(amount_won) AS 28profit FROM tip WHERE date_settled > '$twoeight_daystime' GROUP BY user_id) as t3 ON user.user_id = t3.user_id where activated = 1 GROUP BY user.user_id ORDER BY user.date_added DESC"); return $query->result_array(); The query works fine running it in phpMyAdmin and returns complete results (in image attached). However, printing the array in CodeIgniter, it has no value for one field ,seven_profit, where it is there in the SQL query ran in phpMyAdmin, just the discrepancy in this one field, from sql to php array... I just can’t see why, when printing the array, that one field, which should have value of 26, contains nothing? Any ideas? I changed the field name from starting with a number in attempt to fix it, but no difference. I know this is complex and looks horrible, any help or just people coming across something similar would be great to know about, thanks. Sam

  • Calculating Length Based on Sensor Data

    - by BSchlinker
    I've got an IR sensor which writes its current information to a token which I then interpret in a C# application. That's all good -- no problems there, heres my code: SetLabelText(tokens [1],label_sensorValue); sensorreading = Int32.Parse(tokens[0]); sensordistance = (mathfunctionhere); Great. So the further away the IR sensor is from an object, the lower the sensor reading (as less light is reflected back and received by the sensor). My problem is in interpreting that length. I can go ahead and get lets say "110" as a value when an object is 5 inches away, and then "70" as a value when an object is 6 inches away. Now I want to be able to calculate the distance of an object using these constants for any length. Any ideas?

  • What is a faster way of merging the values of this Python structure into a single dictionary?

    - by jcoon
    I've refactored how the merged-dictionary (all_classes) below is created, but I'm wondering if it can be more efficient. I have a dictionary of dictionaries, like this: groups_and_classes = {'group_1': {'class_A': [1, 2, 3], 'class_B': [1, 3, 5, 7], 'class_c': [1, 2], # ...many more items like this }, 'group_2': {'class_A': [11, 12, 13], 'class_C': [5, 6, 7, 8, 9] }, # ...and many more items like this } A function creates a new object from groups_and_classes like this (the function to create this is called often): all_classes = {'class_A': [1, 2, 3, 11, 12, 13], 'class_B': [1, 3, 5, 7, 9], 'class_C': [1, 2, 5, 6, 7, 8, 9] } Right now, there is a loop that does this: all_classes = {} for group in groups_and_classes.values(): for c, vals in group.iteritems(): for v in vals: if all_classes.has_key(c): if v not in all_classes[c]: all_classes[c].append(v) else: all_classes[c] = [v] So far, I changed the code to use a set instead of a list since the order of the list doesn't matter and the values need to be unique: all_classes = {} for group in groups_and_classes.values(): for c, vals in group.iteritems(): try: all_classes[c].update(set(vals)) except KeyError: all_classes[c] = set(vals) This is a little nicer, and I didn't have to convert the sets to lists because of how all_classes is used in the code. Question: Is there a more efficient way of creating all_classes (aside from building it at the same time groups_and_classes is built, and changing everywhere this function is called)?

  • Java appending XML data

    - by Travis
    I've already read through a few of the answers on this site but none of them worked for me. I have an XML file like this: <root> <character> <name>Volstvok</name> <charID>(omitted)</charID> <userID>(omitted)</userID> <apiKey>(omitted)</apiKey> </character> </root> I need to add another <character> somehow. I'm trying this but it does not work: public void addCharacter(String name, int id, int userID, String apiKey){ Element newCharacter = doc.createElement("character"); Element newName = doc.createElement("name"); newName.setTextContent(name); Element newID = doc.createElement("charID"); newID.setTextContent(Integer.toString(id)); Element newUserID = doc.createElement("userID"); newUserID.setTextContent(Integer.toString(userID)); Element newApiKey = doc.createElement("apiKey"); newApiKey.setTextContent(apiKey); //Setup and write newCharacter.appendChild(newName); newCharacter.appendChild(newID); newCharacter.appendChild(newUserID); newCharacter.appendChild(newApiKey); doc.getDocumentElement().appendChild(newCharacter); }

  • NHibernate Linq queries not returning data saved in the same transaction

    - by Andrew
    Hi, I have a situation where I am using NHibernate in a WCF service and using a TransactionScope for the transaction management. NHibernate enlists in the ambient transaction fine, but, any changes I make and save inside the transaction, are not visible to any queries I make while still in that transaction. So if I add an entity and session.save() it, then further on in the code, there is a linq query against that entities table, the entity I just added is not returned. Strangely this seems to work fine if I use explicit NHibernate transactions in my tests. Anyone have any ideas as to why and what I can do about it? Many thanks Andrew

  • How can I create multiple identical AWS EC2 server instances with large amounts of persistent data?

    - by mojones
    I have a CPU-intensive data-processing application that I want to run across many (~100,000) input files. The application needs a large (~20GB) data file in order to run. What I would like to do is create an EC2 machine image that has my application and associated data files installed boot up a large number (e.g. 100) of instances of this image split my input files up into 100 batches and send one batch to be processed on each instance I am having trouble figuring out the best way to ensure that each instance has access to the large data file. The data file is too big to fit on the root filesystem of an AMI. I could use Block Storage, but a given Block Storage volume can only be attached to a single instance, so I would need 100 clones. Is there some way to create a custom image that has more space on the root filsystem so that I can include my large data file? Or is there a better way to tackle this problem?

  • Working with Decimal fields in SSIS

    - by CoffeeAddict
    I'm using SQL Server 2008 w/SP2. I've got an incoming decimal(9,2) field incoming through my OLE DB transformation to my recordset destination transformation. It's like it's reading it as something other than a decimal? I don't know..I'm not an SSIS guru. So continuing on...the problem I have starts here with me trying to stuff the value into a variable for this decimal field. In a foreach loop, I have a variable to represent this decimal field so I can work with it. The first problem that I believe is pretty well known is SSIS variables do not have a decimal type. And from my own testing and what I've read out there, people are using type object for the variable to make SSIS "happy" with decimal values? It makes mine happy. But, then in my foreach loop, I have a for loop. And inside that I'm using an E*xecute SQL Task transformation*. In it, I need to create a parameter mapping to my variable so I can work with that decimal field in my T-SQL call in here. So now I see a type decimal for the parameter and use it and set that to point to my variable. When I run SSIS and it hits my SQL call, I get this in my output window.: The type is not supported.DBTYPE_DECIMAL So I am hitting a wall here. All I wanna do is work with a decimal!!!

  • Problem pulling data from website in .NET and C#

    I have written a web scraping program to go to a list of pages and write all the html to a file. The problem is that when I pull a block of text some of the characters get written as '?'. How do I pull those characters into my text file? Here is my code: string baseUri = String.Format("http://www.rogersmushrooms.com/gallery/loadimage.asp?did={0}&blockName={1}", id.ToString(), name.Trim()); // our third request is for the actual webpage after the login. HttpWebRequest request = (HttpWebRequest)WebRequest.Create(baseUri); request.Method = "GET"; request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)"; //get the response object, so that we may get the session cookie. HttpWebResponse response = (HttpWebResponse)request.GetResponse(); StreamReader reader = new StreamReader(response.GetResponseStream()); // and read the response string page = reader.ReadToEnd(); StreamWriter SW; string filename = string.Format("{0}.txt", id.ToString()); SW = File.AppendText("C:\\Share\\" + filename); SW.Write(page); reader.Close(); response.Close();
