• How to access the theming Fonts and Colors on GTK/Gnome

  - by Lothar

  Lets say i want to write a special text editor widget. How can i get the default themed colors for texts, selected text and background and which are the users default fonts? I see that GNOME does define 5 special system fonts and default sizes for this purpose in the GNOME Appearance Configuration dialog, but i haven't found a single word in the GTK documentation how to access them (and the GTK mailing list is a joke:-( ). Windows and Cocoa both give me dozens of system values. I found the GtkStyle class but this doesn't seem to be what i need.

• C# and MySQL .NET Connector - Any way of preventing SQL Injection attacks in a generic class?

  - by John M

  My idea is to create some generic classes for Insert/Update/Select via a C# (3.5) Winforms app talking with a MySQL database via MySQL .NET Connector 6.2.2. For example: public void Insert(string strSQL) { if (this.OpenConnection() == true) { MySqlCommand cmd = new MySqlCommand(strSQL, connection); cmd.ExecuteNonQuery(); this.CloseConnection(); } } Then from anywhere in the program I can run a query with/without user input by just passing a SQL query string. Reading around on SO is starting to give me the indication that this may lead to SQL injection attacks (for any user-input values). Is there anyway of scrubbing the inputted strSQL or do I need to go and create individual parameterized queries in every method that needs to do a database function?

• annotation in matlab plot

  - by Tim

  Hi, I just wonder how to add annotation in matlab plot? Here is my code: plot(x,y); annotation('textarrow',[x, x+0.05],[y,y+0.05],'String','my point','FontSize',14); But the arrow points to the wrong place. How can I fix it? And any better idea for annotating a plot? Thanks and regards! EDIT: I just saw from the help document: annotation('line',x,y) creates a line annotation object that extends from the point defined by x(1),y(1) to the point defined by x(2),y(2), specified in normalized figure units. In my code, I would like the arrow pointing to the point (x,y) that is drawn by plot(), but annotation interprets the values of x and y as in normalized figure units. So I think that is what causes the problem. How can I specify the correct coordinates to annotation?

• Jabber .net rostertree error

  - by Farooq

  Hi, Whenever I add the rostertree control to my form, I can see that the PresenceManager and RosterManager property values for it have this error listed: "Unable to cast object of type 'System.Windows.Forms.DataGridViewTextBoxColumn' to type 'System.ComponentModel.Component'." I can compile the solution and all but this error keeps popping up randomly. Can someone advice when this may happen. I'm thinking it has to do with the controls not being added properly. I'm using Visual Studio 2008. Thanks.

• How to Filter more than one field using WPF AutoCompleteBox

  - by Drew

  i am trying to customize the suggestions on the AutoCompleteBox in the WPF Tool kit. Right now i have a last name field which when the user enters characters a query runs that retrieves the top 10 records based on that last name. i would also like to filter by first name, i tried splitting out the comma and searching by the last name and the characters entered in the first name. however, as soon as a space or comma is entered into the autocompletebox, the suggest functionality stops working, which I believe is because the ValueMemberPath property is set to be last name. Is there a work around for this, or a way to modify the ValueMemberPath to handle multiple values? Thanks!

• conversion of a varchar to a smalldatetime results in an out-of-range value

  - by michael

  The code: strSql = "insert into table2 (transactiondate) values ('" & transactiondate & "')" seems to be giving me the runtime error: The conversion of a varchar data type to a smalldatetime data type resulted in an out-of-range value In the code, strSql is a String object and transactiondate is a Date object. In the SQL database however, transactiondate is a smalldatetime object. I've tried changing the smalldatetime to a datetime (in the database) and I've tried transactiondate.toString() but with no success. How can this be fixed? Note: I know about the dangers of inline SQL. I am looking for a quick fix solution here and not a discussion about SQL injection.

• how to write re-usable views in django?

  - by rz

  These are the techniques that I use regularly to make my views reusable: take the template_name as an argument with a default take an optional extra_context which defaults to empty {} right before the template is rendered the context is updated with the extra_context for further re-usability, call any callable in extra_context.values() whenever the view deals with a queryset, there is a queryset argument with a default whenever the view needs a particular object from the ORM, it attempts to fetch it using any "id" parameter in several ways (e.g. as a slug, as a database id) (this may be a bad practice...) First, Should I add anything to my list? Should I remove anything from my list? The items accommodates a large number of cases. However, whenever an app extends a model of another in some way (e.g. adding a field or changing the behavior in some way) I end up writing my own views and only reusing the model. Is this normal?

• How do I gain Control of a row in Tabular Layout in Oracle

  - by DotNetDan

  This might be simple but I am new to Oracle. I am using Oracle 10g and have a form that lists our information from a linked table in a tabular Layout. The last column of data is a "list Item" item type that has the Element list of Enabled (T) and Disabled (F). What I need is when a user changes this dropdown, to disabled, I want ONLY that row to have some of the columns be disabled and not the entire column. This is also assuming on load of the form, it will disable and enable rows of data depending on what values are being pulled from the EnabledDisabled column in the database. Thanks for the help!

• How to do an IF statement based on the value of a MySQL table cell?

  - by Susan

  How can I do an if statement based on the value of a mysql table cell. For example, I have a table of people with a column called marital_status. This column has one of two values: yes or no. But this doesn't work: $query = mysql_query("SELECT marital_status FROM people WHERE first_name = 'John'"); while ($row = mysql_fetch_assoc($query)) { $maritalStatus = $row['marital_status']; } if ($maritalStatus == "yes") { echo "This person is married."; } else { echo "This person is NOT married."; } $maritalStatus == "yes" doesn't return as true even though that is exactly the value in that cell.

• Should I replace string patterns in asp.net mvc using a custom viewengine?

  - by Roger Rogers

  Have an ASP.NET MVC site that is localized. The localization functionality adds the two digit language ID to the URL, e.g. /es/Page. If no language Id is found in the URL, the site switches to the user's browser culture. All's good. However, the site's hyperlinks, a mixture of hard-coded href tags, actionlinks, etc., don't include the base language ID, so when clicking through the site the set culture is lost, and the site reverts to the user's browser culture. My (lazy) thought is to replace all href values, that don't point to an external site, with the localized URL (e.g. include the /es/). Otherwise, all site links will need to be updated to include the culture code. Is this just plain dumb? Or, reasonable, and should be done using a custom view engine, or some other approach?

• InnoDB "Column count doesn't match value count at row 1"

  - by Webnet

  I'm having issues with a table. I'm using the following to create my insert query... $validatedData = array(); foreach ($post as $key => $value) { if ($key != 'submit' && $key != 'dz_tos' && $key != 'dz_billShip') { $validatedData[$key] = filter_var($value, FILTER_SANITIZE_STRING); } } mysql_query("INSERT INTO dz_users(".implode(array_keys($validatedData), ',').", dz_access_level) VALUES(\"".implode($validatedData, '\",\"')."\", 1)"); So every column has a value to match it. The problem is that I'm getting the SQL error: Column count doesn’t match value count at row 1 The database is an innoDB and all columns are varChar/Char except for the ID field which is an auto increment primary key.

• Cucumber/Webrat: follow link by CSS class?

  - by Joe

  Hello there, is it possible to follow a link by it's class name instead of the id, text or title? Given I have (haha, cucumber insider he?) the following html code: <div id="some_information_container"> <a href="edit" class="edit_button">Translation here</a> </div> I do not want to match by text because I'd have to care about the translation values in my tests I want to have my buttons look all the same style, so I will use the CSS class. I don't want to assign a id to every single link, because some of them are perfectly identified through the container and the link class Is there anything I missed in Cucumber/Webrat? Or do you have some advices to solve this in a better way? Thanks for your help and best regards, Joe edit: I found an interesting discussion going on about this topic right here - seems to remain an open issue for now. Do you have any other solutions for this?

• Rails transaction: save data in multiple models.

  - by smotchkkiss

  my models class Auction belongs_to :item belongs_to :user, :foreign_key => :current_winner_id has_many :auction_bids end class User has_many :auction_bids end class AuctionBid belongs_to :user end current usage An item is displayed on the page, the user enters an amount and clicks bid. Controller code might look something like this: class MyController def bid @ab = AuctionBid.new(params[:auction_bid]) @ab.user = current_user if @ab.save render :json => {:response => 'YAY!'} else render :json => {:response => 'FAIL!'} end end end desired functionality This works great so far! However, I need to ensure a couple other things happen. @ab.auction.bid_count needs to be incremented by one. @ab.user.bid_count needs to be incremented by one @ab.auction.current_winner_id needs to be set to @ab.user_id That is, the User and the Auction associated with the AuctionBid need values updated as well in order for the AuctionBid#save to return true.

• RadioButtonList.SelectedIndex vs RadioButtonList.SelectedValue

  - by Pinpin

  Out of curiosity, anyone knows the particulars of the internal implementation of ListControl.SelectedIndex = (int) <new valueIndex> VS ListControl.SelectedValue = <new value>.ToString() I'm having difficulties with a custom validation object we've built here to process all validation in one sweep. I suspect using <SelectedValue = > will raise a SelectedIndexChanged event, even though both the value and index remain the same, both before and after the operation. (The ListControl's values are populated declaratively....) As ever, thank you for your time!

• Is it possible to use Regex through Hexadecimal to find email addresses

  - by LukeJenx

  Not sure if this is even possible but I have been looking at using Regex to get an email address that is in Hex. Basically this is to build up some of my automated forensic tools but I am having problems on making a suitable Regex algorithm. Regex for email: /^([a-z0-9_.-]+)@([\da-z.-]+).([a-z.]{2,6})$/ Hex values: @ = 40 . = 2E .com = 636f6d _ = 5f A/a = 41/61 [1] Z/z = 5a/7a - = 2d This is what I have got at the moment (it only takes into account lower case and .com). But it doesn't work! Have I messed something simple up? "/^([61-7a]+)40([61-7a]+)23(636f6d)$/" [1] I know email can only be lower case but I need to take uppercase into account too.

• Sqlite: Selecting records spread over total records

  - by Martin

  I have a sql / sqlite question. I need to write a query that select some values from a sqlite database table. I always want the maximal returned records to be 20. If the total selected records are more than 20 I need to select 20 records that are spread over the total records. It is also important that I always select the first and last value from the table when sorted on the date. I know how to accomplish this in code but it would be perfect to have a sqlite query that can do the same. The query Im using now is really simple and looks like this: "SELECT value,date,valueid FROM tblvalue WHERE tblvalue.deleted=0 ORDER BY DATE(date)" Hope I explained what I need, thanks for your help!

• JTable filled with database data is not being updated when columns are reordered.

  - by marionmaiden

  I have a JTable filled with data of a table of my database (so I used ResultSetTableModel) and using TableRowSorter to sort the rows, as I click in one column of the JTable. The data is displayed in the jTable without problems; But when I sort the JTable by some column table (for example, sorting it by the primary key value), and edit some cell from the sorted jTable, the value changed is the old cell that were in that position before the ordenation of the column. For example: Suppose I have a table with 2 columns - name and age. My table has the following data: c 1 b 2 a 3 when I order i by name in the JTable, it becomes like this a 3 b 2 c 1 if I edit the value "1", after the edition, the table becomes like this a 1 b 2 c 1 It seems that the positions are not being updated in the JTable, and the values are edited considering their original positions.

• How to include javascript/css once with Struts 1.x

  - by Felix

  If this is the wrong approach, please suggest something better, but my current efforts have been trying to find something that exists for a single page load, such that I can cache which javascript/css files have been included so as to only include them once. I thought in a TagSupport subclass I could use (HttpServletRequest)pageContext.getRequest().getParameterMap().put(srcKey,true) but the request is per jsp, not per page load so it was a failure. I could set up a filter in web.xml, but it seems I would have to search the response for duplicates and rewrite the response...pain. I could try to store things in the session, but there are headaches with clearing values... Any help would be appreciated.

• rails accessing value from facebooker hash/array

  - by Ben

  This is my first time using the facebooker plugin with rails, and I'm having trouble accessing user info. The website uses FB connect to authenticate users. I am trying to get the name of the university that the logged in user attends. When I use the command <%= facebook_session.user.education_history[:name] %>, I get an error "Symbol as array index". I have also tried using education_history[1], but that just returns "# Facebooker::EducationInfo:<some sort of alphanumeric hash value>" When I use something like <%= facebook_session.user.relationship_status %> , it returns the relationship status just fine. Similarly, <%= facebook_session.user.hometown_location.city %> returns the city name just fine. I've checked out the documentation for facebooker, but I can't figure out the correct way to get the values I need. Any idea on how to get this to work? Thanks!

• good __eq__, __lt__, ..., __hash__ methods for image class?

  - by Marten Bauer

  I create the following class: class Image(object): def __init__(self, extension, data, urls=None, user_data=None): self._extension = extension self._data = data self._urls = urls self._user_data = user_data self._hex_digest = hashlib.sha1(self._data).hexDigest() Images should be equal when all values are equal. Therefore I wrote: def __eq__(self, other): if isinstance(other, Image) and self.__dict__ == other.__dict__: return True return False def __ne__(self, other): return not self.__eq__(other) def __lt__(self, other): return self.__dict__ < other.__dict__ ... But how should the __hash__ method look like? Equal Images should return equal hashes... def __hash__(self): # won't work !?! return hash(self.__dict__) Is the way I try to use __eq__, __ne__, __lt__, __hash__, ... recommend?

• Creating a CLR UDF with variable number of parameters

  - by josephj1989

  Hi I wanted a function to find the greatest of a list of String values passed in. I want to invoke it as Select greatest('Abcd','Efgh','Zxy','EAD') from sql server. It should return Zxy. The number of parameters is variable.Incidentally it is very similar to oracle GREATEST function. So I wrote a very simple CLR function (Vs2008) and tried to deploy it. See below public partial class UserDefinedFunctions { [Microsoft.SqlServer.Server.SqlFunction] public static SqlString Greatest(params SqlString[] p) { SqlString max=p[0]; foreach (string s in p) max = s.CompareTo(max) > 0 ? s : max; return max; } }; But when I try to compile or deploy it I get the following error Cannot find data type SqlString[]. Is it possible to satisfy my requirement using SQL CLR ?
