  • How can I force input to uppercase in an asp.net textbox?

    - by Aheho
    I'm writing an asp.net application. I have a textbox on a webform and I want to force whatever the user types to upper case. I'd like to do this on the front end. You should also note that there is a validation control on this textbox, so I want to make sure the solution doesn't interfere with the asp.net validation. Clarification: It appears that the CSS text-tranform makes the user input appear in uppercase, however under the hood, it's still lower case as the validation control fails. You see, my validation control checks to see if a valid state code is entered, however the regex expression I"m using only works with uppercase characters.

  • C# - Google like query engine.-

    - by MRFerocius
    Guys; Hope you are fine. I have to make a Web Project (very simple) I will have a DB with 2 tables. One table has 2 fields. From the WebPage I need a Google like search query, for example I have Movie Title and Movie Review on the Table. I need to be able to search those 2 fields like this: "Best Movie" + Action I will need to make a query to the DB to search for the "Best Movie" string togheter plus optional ACTION word on 2 fields of the table. Am I clear??? :) Does somebody know if this has already been made, and if it´s public and free and where to get it :) Thanks in advanced EDIT: My concern is to translate the Google like Symbols ("", +, -, ~) to build a valid query.

  • Are there any languages that are dynamically typed but do not allow weak typing?

    - by Maulrus
    For example, adding a (previously undeclared) int and a string in pseudocode: x = 1; y = "2"; x + y = z; I've seen strongly typed languages that would not allow adding the two types, but those are also statically typed, so it's impossible to have a situation like above. On the other hand, I've seen weakly typed languages that allow the above and are statically typed. Are there any languages that are dynamically typed but are also strongly typed as well, so that the piece of code above would not be valid?

  • My site was recently attacked. What do I do?

    - by ChrisH
    This is a first for me. One of the sites I run was recently attacked. Not at all an intelligent attack - pure brute force - hit every page and every non-page with every extension possible. Posted with garbage data to every form and tried to post to some random urls too. All tod, 16000 requests in one hour. What should I do to prevent/alert this kind of behavior? Is there a way to limit the request/hr for a given ip/client? Is there a place I should be reporting the user to? They appear to be from China and did leave what seems like a valid e-mail.

  • When do you trust the data / variables

    - by Wizzard
    We all know that all user data, GET/POST/Cookie etc etc needs to be validated for security. But when do you stop, once it's converted into a local variable? eg if (isValidxxx($_GET['foo']) == false) { throw InvalidArgumentException('Please enter a valid foo!'); } $foo = $_GET['foo']; fooProcessor($foo); function fooProcessor($foo) { if (isValidxxx($foo) == false) { throw Invalid...... } //other stuff } To me thats over the top. But what if you load the value from the database... I hope I make sense :)

  • recursive program

    - by wilson88
    I am trying to make a recursive program that calculates interest per year.It prompts the user for the startup amount (1000), the interest rate (10%)and number of years(1).(in brackets are samples) Manually I realised that the interest comes from the formula YT(1 + R)----- interest for the first year which is 1100. 2nd year YT(1 + R/2 + R2/2) //R squared 2nd year YT(1 + R/3 + R2/3 + 3R3/) // R cubed How do I write a recursive program that will calculate the interest? Below is the function which I tried double calculateInterest(double startUp, double rate, double duration) { double cpdInterest = (duration*startUp)*(1 + rate); if (duration == 0) { return cpdInterest; } else if (duration < 0) { cout << "Please enter a valid year"; } else { calculateInterest(cpdInterest,rate,duration); } return cpdInterest; }

  • Why should I use a container div in HTML?

    - by lara.robertson
    I am currently learning html/css, and have noticed a common technique is to place a generic container div in the root of the body tag: <html> <head> ... </head> <body> <div id="container"> ... </div> </body> </html> Is there a valid reason for doing this? Why can't the css just reference the body tag?

  • How do you verify the correct data is in a data mart?

    - by blockcipher
    I'm working on a data warehouse and I'm trying to figure out how to best verify that data from our data cleansing (normalized) database makes it into our data marts correctly. I've done some searches, but the results so far talk more about ensuring things like constraints are in place and that you need to do data validation during the ETL process (E.g. dates are valid, etc.). The dimensions were pretty easy as I could easily either leverage the primary key or write a very simple and verifiable query to get the data. The fact tables are more complex. Any thoughts? We're trying to make this very easy for a subject matter export to run a couple queries, see some data from both the data cleansing database and the data marts, and visually compare the two to ensure they are correct.

  • Fluxbox compiling problems after making a change.

    - by Jack
    I'm trying to make the change here: http://fluxbox-wiki.org/index.php?title=Howto_Make_dblclick_titlebar_maximize I am using the current git version of the fluxbox source. I assume that those instructions are perhaps no longer valid for the current git version. In the void FluxboxWindow::setupWindow() function I can see no references to CommandRef or frame. I would like to know if it is possible that I could work out where they should go in that function, with only having a limited knowledge? I am still trying to learn programming and don't know enough just yet to work out where they should go. I assume I can't just paste in the suggested lines anywhere in that function, but why not? I can paste the source if needed, but I am unsure where to paste to.

  • Why should I reuse XmlHttpRequest objects?

    - by Xavi
    From what I understand, it's a best practice to reuse XmlHttpRequest objects whenever possible. Unfortunately, I'm having a hard time understanding why. It seems like trying to reuse XHR objects can increase code complexity, introduce possible browser incompatibilities, and lead to other subtle bugs. After researching this question for a while, I did come up with a list of possible explanations: Fewer objects created means less garbage collecting Reusing XHR objects reduces the chance of memory leaks The overhead of creating a new XHR object is high The browser is able to perform some sort of network optimization under hood But I'm not sure if any of these reasons are actually valid. Any light you can shed on this question would be much appreciated.

  • Python: Dynamic attribute name generation without exec() or eval()

    - by PyNewbie27
    Hi, I'm trying to dynamically create buttons at runtime with PyQT4.7 However, this being my first python program I'm not sure how to get the functionality I want. I would like to be able to substitute a text string for an attribute name: i.e. for each in xrange(4): myname = "tab1_button%s" % each #tab1_button0, tab1_button1, tab1_button2 #self.ui.tab1_button0 = QtGui.QPushButton(self.ui.tab) <--normal code to create a named button setattr(self.ui,myname,QtGui.QPushButton(self.ui.tab)) #rewrite of line above to dynamicly generate a button #here's where I get stuck. this code isn't valid, but it shows what i want to do self.ui.gridLayout.addWidget(self.ui.%s) % myname #I need to have %s be tab1_button1, tab1_button2, etc. I know the % is for string substituion but how can I substitute the dynamically generated attribute name into that statement? I assume there's a basica language construct I'm missing that allows this. Since it's my first program, please take it easy on me ;)

  • .NET interview, code structure and the design

    - by j_lewis
    I have been given the below .NET question in an interview. I don’t know why I got low marks. Unfortunately I did not get a feedback. Question: The file hockey.csv contains the results from the Hockey Premier League. The columns ‘For’ and ‘Against’ contain the total number of goals scored for and against each team in that season (so Alabama scored 79 goals against opponents, and had 36 goals scored against them). Write a program to print the name of the team with the smallest difference in ‘for’ and ‘against’ goals. the structure of the hockey.csv looks like this (it is a valid csv file, but I just copied the values here to get an idea) Team - For - Against Alabama 79 36 Washinton 67 30 Indiana 87 45 Newcastle 74 52 Florida 53 37 New York 46 47 Sunderland 29 51 Lova 41 64 Nevada 33 63 Boston 30 64 Nevada 33 63 Boston 30 64 Solution: class Program { static void Main(string[] args) { string path = @"C:\Users\<valid csv path>"; var resultEvaluator = new ResultEvaluator(string.Format(@"{0}\{1}",path, "hockey.csv")); var team = resultEvaluator.GetTeamSmallestDifferenceForAgainst(); Console.WriteLine( string.Format("Smallest difference in ‘For’ and ‘Against’ goals > TEAM: {0}, GOALS DIF: {1}", team.Name, team.Difference )); Console.ReadLine(); } } public interface IResultEvaluator { Team GetTeamSmallestDifferenceForAgainst(); } public class ResultEvaluator : IResultEvaluator { private static DataTable leagueDataTable; private readonly string filePath; private readonly ICsvExtractor csvExtractor; public ResultEvaluator(string filePath){ this.filePath = filePath; csvExtractor = new CsvExtractor(); } private DataTable LeagueDataTable{ get { if (leagueDataTable == null) { leagueDataTable = csvExtractor.GetDataTable(filePath); } return leagueDataTable; } } public Team GetTeamSmallestDifferenceForAgainst() { var teams = GetTeams(); var lowestTeam = teams.OrderBy(p => p.Difference).First(); return lowestTeam; } private IEnumerable<Team> GetTeams() { IList<Team> list = new List<Team>(); foreach (DataRow row in LeagueDataTable.Rows) { var name = row["Team"].ToString(); var @for = int.Parse(row["For"].ToString()); var against = int.Parse(row["Against"].ToString()); var team = new Team(name, against, @for); list.Add(team); } return list; } } public interface ICsvExtractor { DataTable GetDataTable(string csvFilePath); } public class CsvExtractor : ICsvExtractor { public DataTable GetDataTable(string csvFilePath) { var lines = File.ReadAllLines(csvFilePath); string[] fields; fields = lines[0].Split(new[] { ',' }); int columns = fields.GetLength(0); var dt = new DataTable(); //always assume 1st row is the column name. for (int i = 0; i < columns; i++) { dt.Columns.Add(fields[i].ToLower(), typeof(string)); } DataRow row; for (int i = 1; i < lines.GetLength(0); i++) { fields = lines[i].Split(new char[] { ',' }); row = dt.NewRow(); for (int f = 0; f < columns; f++) row[f] = fields[f]; dt.Rows.Add(row); } return dt; } } public class Team { public Team(string name, int against, int @for) { Name = name; Against = against; For = @for; } public string Name { get; private set; } public int Against { get; private set; } public int For { get; private set; } public int Difference { get { return (For - Against); } } } Output: Smallest difference in for' andagainst' goals TEAM: Boston, GOALS DIF: -34 Can someone please review my code and see anything obviously wrong here? They were only interested in the structure/design of the code and whether the program produces the correct result (i.e lowest difference). Much appreciated. "P.S - Please correct me if the ".net-interview" tag is not the right tag to use"

  • Handling Data Hierarchies in code

    - by Miau
    Hi there So, say I have a string to parse with a given format that maps to a tree like data structure. The string is kinda similar to a folder path, and the structure is similar to a file structure, except its got some rules so for something@cat1@otherSomething you would get /something/cat1/otherSomething for something@cat2@otherSomething you would get /something/cat2/otherSomething other examples /OtherThing/cat1/otherSomething/Blah /OtherThing/cat4/otherSomething Where something, cat1, otherSomethign, etc are some sort of instances of ICategory There are certain rules that control what subcategories are valid and which subcategories are not acceptable, at the moment I m considering a heavy Object hierachy, but I know this is not a flexible solution, I d prefer the categories to be a bit more general but again, since there are rules about what can go next I m not sure how to do this. An example of a rule can be: OtherThing can only have subcategories cat1 and cat4 ( anything else is invalid) An option would be to use some sort of convention based aproach to instantiate a particular class given a subsection of the string(like cat4) but it seems a bit too complex, I m all ears Thanks

  • How does one pre-populate a Python Formish form?

    - by Jace
    How does one pre-populate a Formish form? The obvious method as per the documentation doesn't seem right. Using one of the provided examples: import formish, schemaish structure = schemaish.Structure() structure.add( 'a', schemaish.String() ) structure.add( 'b', schemaish.Integer() ) schema = schemaish.Structure() schema.add( 'myStruct', structure ) form = formish.Form(schema, 'form') If we pass this a valid request object: form.validate(request) The output is a structure like this: {'myStruct': {'a': 'value', 'b': 0 }} However, pre-populating the form using defaults requires this: form.defaults = {'myStruct.a': 'value', 'myStruct.b': 0} The dottedish package has a DottedDict object that can convert a nested dict to a dotted dict, but this asymmetry doesn't seem right. Is there a better way to do this?

  • Using perl's Regexp::Grammars, how do I make a capture dependent on $MATCH?

    - by Evan Carroll
    I've got a token like such: <delim2=((?{ $MATCH{delim} }))> and what I want to happen is for delim2 to capture and be set to the value of delim. When I run this, delim2 is set, but the capture is never done. I think this is an error in my reasoning: I'm trying to chain this form: <ALIAS= ( PATTERN )> Match pattern, save match in $MATCH{ALIAS} and this form: (?{ MATCH{delim} }) into something like this <ALIAS= ( (?{MATCH{delim}) )> Matches the value of $MATCH{delim} save to $MATCH{delim2} but this simply doesn't seem valid. I can verify my original token works <delim2=((?{ die $MATCH{delim} }))> will die with the value, and, if I hard code it, I get the right capture and everything works <delim2=(')>? So how do I go about achieving sane results, while having a dynamic pattern?

  • glDrawElements allocating memory and not releasing it

    - by Joshua Weinberg
    Using OpenGLES 1.1 on the iPhone 3G (device, not simulator), I do normal drawing fun. But at points during the run of the application I get giant memory spikes, after a lot of digging with instruments I have found that it is glDrawElements that is grabbing the memory. The buffer being allocated is 4 meg, which to me means its loading a texture into RAM, which I guess could be valid, but its never releasing this buffer, and is allocating multiple of them. How do I make sure that these buffers that GL is creating get destroyed, instead of just hanging around?

  • jQuery Validation 1.10 and MVC server-side errors

    - by sam360
    This feature used to work just fine on my website. If I added a custom error to ModelState, the input on the page would be marked as "input-validation-error" and the Html.ValidationMessage() would take care of rendering a span with the error message inside it. Due to incompatibility reasons we had to upgrade our jQuery Validation to 1.10: Now when I add a custom error to ModelState, I can debug and see that the HTML elements being rendered correctly, but as soon as the page load is completed, jQuery Validation removes the error message and set the "class" attribute of the input to "valid"! Has any one else come across this issue? UPDATE Testing further shows that the error message is shown on the screen until the field gains focus. As soon as the field gains focus jQuery Validation removes the customer server-side error message and marks the field as good.

  • Is there a list of language only character regions for UTF-8 somewhere?

    - by Brehtt
    I'm trying to analyze some UTF-8 encoded documents in a way that recognizes different language characters. For my approach to work I need to ignore non-language characters, such as control characters, mathematical symbols etc. Just trying to dissect the basic Latin section of the UTF standard has resulted in multiple regions, with characters like the division symbol being right in the middle of a range of valid Latin characters. Is there a list somewhere that identifies these regions? Or better yet, a Regex that defines the regions or something in C# that can identify the different characters?
