• I have a SID of a user account, and I want the SIDs of the groups it belongs to. (C#)

  - by JCCyC

  This has to be obtained from a remote machine. The following query works not for SIDs, but for group and account names. "SELECT GroupComponent FROM Win32_GroupUser WHERE PartComponent = \"Win32_UserAccount.Domain='" + accountDomain + "',Name='" + accountName + "'\"" The Win32_Group objects it returns come in the forms of strings, and they only have domain and name (even though Win32_Group has a SID property). I have this sinking feeling I'll have to: Turn the SID into an account name by querying Win32_SID; Perform the query above; Turn each of the resulting group names into SIDs by querying Win32_Group. PLEASE tell me there's a better way.

• Need a cleaner way, which avoids too many 'if statements', to write this method for inputing data in

  - by indiehacker

  What is the best way to reference datastore model attributes without using the four 'if statements' I have in the below sample code, which seem messy and inefficient. For real-world code I may have a situation of 100 attributes such as self.var1, self.var2, ... self.varN that I want to some how reference with just an integer (or strings) as an argument to some method. class PixelObject(db.Model): zoom0 = db.ListProperty(int) zoom1 = db.ListProperty(int) zoom2 = db.ListProperty(int) zoom3 = db.ListProperty(int) zoom4 = db.ListProperty(int) def inputZoomData(self, zoomInteger, input_data): """input_data goes to specified attribute based on if 0,1,2,3,or 4 is argument""" if zoomInteger == 0: self.zoom0 = input_data if zoomInteger == 1: self.zoom1 = input_data if zoomInteger == 2: self.zoom2 = input_data if zoomInteger == 3: self.zoom3 = input_data if zoomInteger == 4: self.zoom4 = input_data

• How to iterate into a string for a word after a fixed keyword? [closed]

  - by Parth

  Possible Duplicate: I need to iterate a loop to every time find the string appearing after a particular string say “if(OLD.”, then which PHP function will be helpful for me? This is the string BEGIN IF (NEW.name != OLD.name) THEN INSERT INTO jos_menuaudit set menuid=OLD.id, oldvalue = OLD.name, newvalue = NEW.name, field = "name"; END IF; IF (NEW.alias != OLD.alias) THEN INSERT INTO jos_menuaudit set menuid=OLD.id, oldvalue = OLD.alias, newvalue = NEW.alias, field = "alias"; END IF; END in which I am searching the particular word after " IF (NEW.", and after that particular others strings should not be displayed, hence whenever in a loop it finds " IF (NEW." I must get a word just next to it. And in this way an array should be ready for to use.

• A better way to do XML in Java

  - by jboyd

  There are a lot of questions that ask the best XML parser, I am more interested in what is the XML parser that is the most like Groovy for Java? I want: SomeApiDefinedObject o = parseXml( xml ); for( SomeApiDefinedObject it : o.getChildren() ) { System.out.println( it.getAttributes() ); } The most important things are that I don't want to create an object for every type of filed, I'd rather just deal with them all as strings, and that building the XML doesn't require any converters or anything, just a simple object that is already defined If you have used the Groovy XML parser, you will know what I'm talking about Alternatively, would it be better for me to just use Groovy from Java?

• Converting a date string which is before 1970 into a timestamp in MySQL.

  - by Jamie

  Not a very good title, so my apologies. For some reason, (i wasn't the person who did it, i digress) we have a table structure where the field type for a date is varchar. (odd). We have some dates, such as: 1932-04-01 00:00:00 and 1929-07-04 00:00:00 I need to do a query which will convert these date strings into a unix time stamp, however, in my sql if you convert a date which is before 1970 it will return 0. Any ideas? Thanks so much! EDIT: Wrong date format. ooops.

• Override .Net Resource file in Calling Application

  - by Blatfrig

  I have an asp.net 2.0 web application that is calling class library. A fairly common scenario to be sure. The class library is making use of a number of resource files and a ResourceManager object to set localised strings. This works absolutely fine in most circumstances based on the user's browser settings. However there are some circumstances under which I wish to overrride the resource string in the class library from within the web application. Is this possible? if so how?

• Check if a class is subclass of another class in Java

  - by craesh

  Hi! I'm playing around with Java's reflection API and trying to handle some fields. Now I'm stuck with identifying the type of my fields. Strings are easy, just do myField.getType().equals(String.class). The same applies for other non-derived classes. But how do I check derived classes? E.g. LinkedList as subclass of List. I can't find any isSubclassOf(...) or extends(...) method. Do I need to walk through all getSuperClass() and find my supeclass by my own? Thanks! craesh

• C: Pointers to any type?

  - by dragme

  I hear that C isn't so type-safe and I think that I could use that as an advantage for my current project. I'm designing an interpreter with the goal for the VM to be extremely fast, much faster than Ruby and Python, for example. Now I know that premature optimization "is the root of all evil" but this is rather a conceptual problem. I have to use some sort of struct to represent all values in my language (from number over string to list and map) Would the following be possible? struct Value { ValueType type; void* value; } I would store the actual values elsewhere, e.g: a separate array for strings and integers, value* would then point to some member in this table. I would always know the type of the value via the type variable, so there wouldn't be any problems with type errors. Now: Is this even possible in terms of syntax and typing?

• Disambiguating Named Entities in Java

  - by Alterscape

  I have a list of strings (company names, in this case), and a Java program that extracts a list of things that look like company names out of mostly-unstructured text. I need to match each element of extracted text to a string in the list. Caveat: the unstructured text has typos, things like "Blah, Inc." referred to as "Blah," etc. I've tried Levenshtein Edit Distance, but that fails for predictable reasons. Are there known best-practices ways of tackling this problem? Or am I back to manual data-entry?

• Most efficient way to remove special characters from string

  - by ObiWanKenobi

  I want to remove all special characters from a string. Allowed characters are A-Z (uppercase or lowercase), numbers (0-9), underscore (_), or the dot sign (.). I have the following, it works but I suspect (I know!) it's not very efficient: public static string RemoveSpecialCharacters(string str) { StringBuilder sb = new StringBuilder(); for (int i = 0; i < str.Length; i++) { if ((str[i] >= '0' && str[i] <= '9') || (str[i] >= 'A' && str[i] <= 'z' || (str[i] == '.' || str[i] == '_'))) sb.Append(str[i]); } return sb.ToString(); } What is the most efficient way to do this? What would a regular expression look like, and how does it compare with normal string manipulation? The strings that will be cleaned will be rather short, usually between 10 and 30 characters in length.

• Set Page Output Cache VaryByCustom value programmatically

  - by Chris Marisic

  I want to use an Enum value for the types of VaryByCustom parameters I will support, is it possible to do this? I tried setting it in the page itself <%@ OutputCache Duration="600" VaryByParam="none" VaryByCustom='<%=VaryByCustomType.IsAuthenticated.ToString(); %>' %> But this returned the entire literal string "<%=VaryByCustomType.IsAuthenticated.ToString(); %>" inside my global.asax is there any way to do this either on the page itself or from the codebehind? Or is this just something I have to accept is purely magic strings and nothing I can do to add type safety to it?

• Compare two object lists with LINQ on specific property

  - by Niklas

  I have these two lists (where the Value in a SelectListItem is a bookingid): List<SelectListItem> selectedbookings; List<Booking> availableBookings; I need to find the ids from selectedBookings that are not in availableBookings. The LINQ join below will only get me the bookingids that are in availableBookings, and I'm not sure how to do it the other way around. != won't work since I'm comparing strings. results = ( from s in selectedbookings join a in availableBookings on s.bookingID.ToString() equals a.Value select s);

• Excel plugin: Finding a Chart's Source Data Number Format String

  - by Jack

  I'm currently working on a plugin for excel (using VB.net--not VBA) that will attempt (among other things) to recognize the format of the source data of a chart and configure the chart's series' number format strings appropriately. That is, yearly data should always be two numbers, monthly data should always be a 3-letter month followed by a 2-digit year, etc. The goal is to have a uniform representation across all charts for monthly data, annual data, daily data, etc. My question is this: how do I find the number format string for the cells (or any cell that is part of that series, as I will be assuming all cells that make up a particular series have the same format) that represent the source data for the chart? Note: I can assume that the chart will always point to a range of cells (not, for example, an array of data).

• distinguishing a string with flex

  - by haluk

  Hi, I need to tokenize some strings which will be splitted of according to operators like = and !=. I was successful using regex until the string has != operator. In my case, string was seperated into two parts, which is expected but ! mark is in the left side even it is part of given operator. Therefore, I believe that regex is not suitable for it and I want to benefit from lex. Since I do not have enough knowledge and experience with lex, I am not sure whether it fits my work or not. Basically, I am trying to do replace the right hand side of the operators with actual values from other data. Do you people think that can it be helpful for my case? Thanks.

• how to write regular expression to validate a string using regex in C#

  - by Charu

  I need to validate a user input based on condition. i wrote a regular expression to do so, but it's failing not sure why. Can somebody point where i am making mistake? Regex AccuracyCodeHexRegex = new Regex(@"^[PTQA]((0|8)[01234567]){2}$"); This is what i am trying to validate(If the string is a subset of these strings then it is valid): Phh, Thh, Qhh, Ahh where 'h' is a hex digit in the set {00, 80, 01, 81, 02, 82, 03, 83, 04, 84, 05, 85, 06, 86, 07, 87} Ex: P00 is valid P20 is not valid

• How to get server message correctly

  - by Leo

  Problem I send the message "12345" from the socket server to the client: myPrintWriter.println("12345"); After that I read this message on client: int c; while ((c = inputStream.read( )) != -1) { byte[] buffer2 = new byte[1]; buffer2[0] = (byte) c; String symbol = new String(buffer2 , "UTF-8"); String symbolCode = Integer.toString((int)buffer2[0]); Log.v(symbol, symbolCode); } Log.v("c == -1", "Disconnected"); What I see in log: With out.println("abcrefg"); Why? I think it's line termination symbol. I need to get string "12345" or any other and next strings correctly. Help me please.

• Need some explanation about MS Ajax using PageMethods

  - by Ahmed Said

  I have a project that uses PageMethods to call functions on the server. The server functions (written in C#) return the values as array of strings, without doing any kind of serialization and in the client side (from Js) the accessing of the return values is by using static variable called arguments. I found that sometimes for some users (cases are not repro) sometimes an exception occured "WebServiceFailedException the server method 'Foo' returned invalid data. the 'd' property is missing from JSON." Some searching on google I found that people are serializing the return values using DataContractJsonSerializer class and in js accessing the return value using one of the callback function Example: function OnRequestComplete(result, userContext, methodName) { var Person = eval('(' + result + ')'); alert(Person.Forename); alert(Person.Surname); } So is the first technique is correct? or what?

• RODBC string getting truncated

  - by sayan dasgupta

  Hi all, I am fetching data from MySql Server into R using RODBC. So in one column of the database is a character vector SELECT MAX(CHAR_LENGTH(column)) FROM reqtable; RETURNS 26566 Now I will show you an example how I am running into the problem `library(RODBC) con <- odbcConnect("mysqlcon") rslts <- as.numeric(sqlQuery(con, "SELECT CHAR_LENGTH(column) FROM reqtable LIMIT 10", as.is=TRUE)[,1]) ` returns > rslts [1] 62 31 17 103 30 741 28 73 25 357 where as rslts <- nchar(as.character(sqlQuery(con, "SELECT column FROM reqtable LIMIT 10", as.is=TRUE)[,1])) returns > rslts [1] 62 31 17 103 30 255 28 73 25 255 So strings with length 255 is getting truncated at 255. Is there a way I can get the full string. Thanks

• Silverlight/WPF: Retreiving the size of a `UIElement` once it has been rendered on screen

  - by ondesertverge

  I have the following simple piece of code: var canvas = new Canvas(); foreach (var ztring in strings) { var textblock = new TextBlock(); textblock.Text = ztring; panel.Children.Add(textblock); textblock.Measure(infiniteSize); } At this point I would expect any of the size properties (Height/Width, ActualHeight/ActualWidth, DesiredSize, RenderSize) to give me the size of the textblock. None of them do. ActualHeight always gives 16.0 no matter what size font. ActualWidth changes according to the text length but not the font size. I change the font size on the parent container and not the TextBlock itself. I feel like I am missing some basic element of understanding the manipulation of silverlight elements from within the codebehind. The question is: how do I get the real actual pixel size of my TextBlock?

• PHP validating integers

  - by Mikk

  Hi, I was wondering, what would be the best way to validate an integer. I'd like this to work with strings as well, so I could to something like (string)+00003 - (int)3 (valid) (string)-027 - (int)-27 (valid) (int)33 - (int)33 (valid) (string)'33a' - (FALSE) (invalid) That is what i've go so far: function parseInt($int){ //If $int already is integer, return it if(is_int($int)){return $int;} //If not, convert it to string $int=(string)$int; //If we have '+' or '-' at the beginning of the string, remove them $validate = ($int[0] === '-' || $int[0] === '+')?substr($int, 1):$int; //If $validate matches pattern 0-9 convert $int to integer and return it //otherwise return false return preg_match('/^[0-9]+$/', $validate)?(int)$int:FALSE; } As far as I tested, this function works, but it looks like a clumsy workaround. Is there any better way to write this kind of function. I've also tried filter_var($foo, FILTER_VALIDATE_INT); but it won't accept values like '0003', '-0' etc.

• How to add a suffix at the end of a string in PHP

  - by Golem

  I am trying to add a .html suffix at the end of all strings supplied by the user before it is entered into the database. Here's my code so far: strtolower(str_replace(" ", "_", $postTitle)); The above takes the title of the post the user it trying to make, turns it to lower case, replaces all white spaces with underscores and makes it ready to be entered into a database column called post_url. I just need it to do one more thing and that's to add a .html at the end of each post url. What is the function to do this?

• How can I remove a duplicate object from a MongoDB array?

  - by andrewrk

  My data looks like this: foo_list: [ { id: '98aa4987-d812-4aba-ac20-92d1079f87b2', name: 'Foo 1', slug: 'foo-1' }, { id: '98aa4987-d812-4aba-ac20-92d1079f87b2', name: 'Foo 1', slug: 'foo-1' } { id: '157569ec-abab-4bfb-b732-55e9c8f4a57d', name: 'Foo 3', slug: 'foo-3' } ] Where foo_list is a field in a model called Bar. Notice that the first and second objects in the array are complete duplicates. Aside from the obvious solution of switching to PostgresSQL, what MongoDB query can I run to remove duplicate entries from foo_list? Similar answers that do not quite cut it: http://stackoverflow.com/a/16907596/432 http://stackoverflow.com/a/18804460/432 These questions answer the question if the array had bare strings in it. However in my situation the array is filled with objects. I hope it is clear that I am not interested in a query; I want the duplicates to be gone from the database forever.

• C#: multicolumn sorting of DataGridView

  - by Bi

  I have a DataGridView in a windows form with 3 columns: Serial number, Name, and Date-Time. The Name column will always have either of the two values: "name1" or "name2". I need to sort these columns such that the grid displays all the rows with name values in a specific order (first display all the "name1" rows and then all the "name2" rows). Within the "name1" rows, I want the rows to be sorted by the Date-Time. Please note programmatically, all the 3 columns are strings. For example, if I have the rows: 01 |Name1 | 2010-05-05 10:00 PM 02 |Name2 | 2010-05-02 08:00 AM 03 |Name2 | 2010-05-01 08:00 AM 04 |Name1 | 2010-05-01 11:00 AM 05 |Name1 | 2010-05-04 07:00 AM needs to be sorted as 04 |Name1 | 2010-05-01 11:00 AM 05 |Name1 | 2010-05-04 07:00 AM 01 |Name1 | 2010-05-05 10:00 PM 03 |Name2 | 2010-05-01 08:00 AM 02 |Name2 | 2010-05-02 08:00 AM I am not sure how to go about using the below: myGrid.Sort(.....,ListSortDirection.Ascending)

• parsing primitive types using java.util.Scanner

  - by Rich Fluckiger

  I'm new to java so forgive the noob question. I have created a swing application that basically has three input strings in JTextFields: loanAmount, interestRate and loanYears and a single submit button with the EventAction. I'm trying to use the java.util.Scanner to parse the input to primitive types that I can use in calculations. I'm getting an error in NetBeans indicating that my variables are not recognized? should I not be calling System.in? private void submitButtonActionPerformed(java.awt.event.ActionEvent evt) { Scanner keyInput = new Scanner(System.in); while (true) try{ double amount = keyInput.nextDouble(loanAmount.getText()); double interest = keyInput.nextDouble(interestRate.getText()); int years = keyInput.nextInt(loanYears.getText()); } catch (NumberFormatException nfe){ } }

• Difference of answers while using split function in Ruby

  - by N L

  Given the following inputs: line1 = "Hey | Hello | Good | Morning" line2 = "Hey , Hello , Good , Morning" file1=length1=name1=title1=nil Using ',' to split the string as follows: file1, length1, name1, title1 = line2.split(/,\s*/) I get the following output: puts file1,length1,name1,title1 >Hey >Hello >Good >Morning However, using '|' to split the string I receive a different output: file1, length1, name1, title1 = line2.split(/|\s*/) puts file1,length1,name1,title1 >H >e >y Both the strings are same except the separating symbol (a comma in first case and a pipe in second case). The format of the split function I am using is also the same except, of course, for the delimiting character. What causes this variation?
