  • HOWTO - Compare a date string to datetime in SQL Server?

    - by Guy
    In SQL Server I have a DATETIME column which includes a time element. Example: '14 AUG 2008 14:23:019' What is the best method to only select the records for a particular day, ignoring the time part? Example: (Not safe, as it does not match the time part and returns no rows) DECLARE @p_date DATETIME SET @p_date = CONVERT( DATETIME, '14 AUG 2008', 106 ) SELECT * FROM table1 WHERE column_datetime = @p_date Note: Given this site is also about jotting down notes and techniques you pick up and then forget, I'm going to post my own answer to this question as DATETIME stuff in MSSQL is probably the topic I lookup most in SQLBOL. Update Clarified example to be more specific. Edit Sorry, But I've had to down-mod WRONG answers (answers that return wrong results). @Jorrit: WHERE (date>'20080813' AND date<'20080815') will return the 13th and the 14th. @wearejimbo: Close, but no cigar! badge awarded to you. You missed out records written at 14/08/2008 23:59:001 to 23:59:999 (i.e. Less than 1 second before midnight.)

  • foreach loop...........

    - by nisardotnet
    I have two questions 1) my interface i have interface called IRegister and within it i have another interface called IPerson, is that right practice? 2) i have two List(IRegister, IPerson) both can have one or more rows. what is the best way to loop both List? within GetValidationRules? public interface IRegister { string FirstName { get; } string MiddleName { get; } string LastName { get; } string EmailAddress { get; } List Student { get; } } public static List GetValidationRules(List register) { List validationRules = new List(); foreach (IRegister myregister in register) { if (string.IsNullOrEmpty(myregister.FirstName)) validationRules.Add(new ValidationRule("Reg", "Must have aFirst Name")); if (string.IsNullOrEmpty(myregister.LastName)) validationRules.Add(new ValidationRule("Reg", "Must have a Last Name")); if (string.IsNullOrEmpty(myregister.EmailAddress)) validationRules.Add(new ValidationRule("Reg", "Must have a Email Address")); IPerson here? how }

  • How to retrieve value from ViewData when the object is not a string?

    - by Richard77
    Hello, Here's the functionality I'd like to exploit: I've a class myClass and would like to iterate over a collection that contains all the properties of that class. I'd like to send the index of that collection along with the other data so that I can control the each sequence of the iteration. Here's simplified versions of a Action method and View (I'll use the same action-view for that functionality). 1) Action public ActionResult CreateHierarchy(int? index) { if(index < PropertiesOfMyClass.Lenght) { //Other code omitted ViewData["index"] = ((index == null) ? 1 : index++); Return View(); } } 2)View <% Using(Html.BeginForm()){%> //Other Code omitted <% = Html.Hidden("Index", ViewData["index"])%> <input type = "submit" value = "Do someting"/> <%}%> I've also placed this at the bottom of the page so that I can check the value of the index, <% = ViewData["index"]%> Unfortunately, its not working. I'm getting only the number 1. I'm missing something? such as a cast for the Viewdata? Should I write something like this: <% = Html.Hidden("index", (int)ViewData["index"])%> It's not working either Thanks for helping

  • Text Decoding Problem

    - by Jason Miesionczek
    So given this input string: =?ISO-8859-1?Q?TEST=2C_This_Is_A_Test_of_Some_Encoding=AE?= And this function: private string DecodeSubject(string input) { StringBuilder sb = new StringBuilder(); MatchCollection matches = Regex.Matches(inputText.Text, @"=\?(?<encoding>[\S]+)\?.\?(?<data>[\S]+[=]*)\?="); foreach (Match m in matches) { string encoding = m.Groups["encoding"].Value; string data = m.Groups["data"].Value; Encoding enc = Encoding.GetEncoding(encoding.ToLower()); if (enc == Encoding.UTF8) { byte[] d = Convert.FromBase64String(data); sb.Append(Encoding.ASCII.GetString(d)); } else { byte[] bytes = Encoding.Default.GetBytes(data); string decoded = enc.GetString(bytes); sb.Append(decoded); } } return sb.ToString(); } The result is the same as the data extracted from the input string. What am i doing wrong that this text is not getting decoded properly?

  • C#, WPF. Length of string that will fit in a specific width.

    - by Ian
    Hi, I'm sure I'm missing something obvious, I have an area in which I intend to draw text. I know its (the area) height and width. I wish to know how many characters/Words will fit in the width, characters preferably. Second question, If the line is too long I'll want to draw a second line, so I guess I need to get the height of the text as well, including what ever it considers the right vertical padding? I'd also rather like to know the inverse, i.e. how many characters I can fit in a specific width. I assume the fact that WPF isn't constrained to pixels will have some bearing on the answer? Ultimately I'm planning on wrapping text around irregular shaped images embedded in the text. Any pointers in the right direction would be great. Thanks

  • Faster way to perform checks on method arguments

    - by AndyC
    This is mostly just out of curiosity, and is potentially a silly question. :) I have a method like this: public void MyMethod(string arg1, string arg2, int arg3, string arg4, MyClass arg5) { // some magic here } None of the arguments can be null, and none of the string arguments can equal String.Empty. Instead of me having a big list of: if(arg1 == string.Empty || arg1 == null) { throw new ArgumentException("issue with arg1"); } is there a quicker way to just check all the string arguments? Apologies if my question isn't clear. Thanks!

  • How do I replace custom "tags" in a string?

    - by Fake Code Monkey Rashid
    Given the following: $foo = "Yo [user Cobb] I heard you like dreams so I put a dream in yo dream in yo dream so you can dream while you dream while you dream." I'd like to do this: $foo = bar($foo); echo $foo; And get something like this: Yo Cobb I heard you like dreams so I put a dream in yo dream in yo dream so you can dream while you dream while you dream. I'm unsure of how the bar function should work. I think this is doable with regular expressions but I personally find those hard to understand. Using the strpos function is another method but I wonder if there is a better solution. Pseudocode is fine but actual code will be appreciated.

  • Simple way to encode a string according to a password?

    - by RexE
    Does Python have a built-in, simple way of encoding/decoding strings using a password? Something like this: >>> encode('John Doe', password = 'mypass') 'sjkl28cn2sx0' >>> decode('sjkl28cn2sx0', password = 'mypass') 'John Doe' I would like to use these encrypted strings as URL parameters. My goal is obfuscation, not strong security. I realize I could use a database table to store keys and values, but am trying to be minimalist.

  • Pulling out two separate words from a string using reg expressions?

    - by Marvin
    I need to improve on a regular expression I'm using. Currently, here it is: ^[a-zA-Z\s/-]+ I'm using it to pull out medication names from a variety of formulation strings, for example: SULFAMETHOXAZOLE-TRIMETHOPRIM 200-40 MG/5ML PO SUSP AMOX TR/POTASSIUM CLAVULANATE 125 mg-31.25 mg ORAL TABLET, CHEWABLE AMOXICILLIN TRIHYDRATE 125 mg ORAL TABLET, CHEWABLE AMOX TR/POTASSIUM CLAVULANATE 125 mg-31.25 mg ORAL TABLET, CHEWABLE Amoxicillin 1000 MG / Clavulanate 62.5 MG Extended Release Tablet The resulting matches on these examples are: SULFAMETHOXAZOLE-TRIMETHOPRIM AMOX TR/POTASSIUM CLAVULANATE AMOXICILLIN TRIHYDRATE AMOX TR/POTASSIUM CLAVULANATE Amoxicillin The first four are what I want, but on the fifth, I really need "Amoxicillin / Clavulanate". How would I pull out patterns like "Amoxicillin / Clavulanate" (in fifth row) while missing patterns like "MG/5 ML" (in the first row)?

  • Html string replace a span's class doesn't work in IE?

    - by SeanJA
    Someone tried to recreate smarty in js: // actually from a template file, not hardcoded in the javascript html = '<span class="{test}">yay</span>'; html = change(html, 'test', 'foo bar'); function change(html, key, value){ html = html.replace('{'+key+'}',value); html = html.replace('%7B'+key+'%7D',value); return html; } element.innerHTML = html; In FF this works fine (as expected): yay In IE 7/8 and probably 6... it gives me this: <span class="foo" bar="">yay</span> Why does it create the extra attribute instead of doing what I expected it to do?

  • Initializing "new users" in Rails

    - by mathee
    I'm creating a Ruby on Rails application, and I'm trying to create/login/logout users. This is the schema for Users: create_table "users", :force => true do |t| t.string "first_name" t.string "last_name" t.text "reputation" t.integer "questions_asked" t.integer "answers_given" t.string "request" t.datetime "created_at" t.datetime "updated_at" t.string "email_hash" t.string "username" t.string "hashed_password" t.string "salt" end The user's personal information (username, first/last names, email) is populated through a POST. Other things such as questions_asked, reputation, etc. are set by the application, so should be initialized when we create new users. Right now, I'm just setting each of those manually in the create method for UsersController: def create @user = User.new(params[:user]) @user.reputation = 0 @user.questions_asked = 0 @user.answers_given = 0 @user.request = nil ... end Is there a more elegant/efficient way of doing this?

  • Is there a Boost (or other common lib) type for matrices with string keys?

    - by mohawkjohn
    I have a dense matrix where the indices correspond to genes. While gene identifiers are often integers, they are not contiguous integers. They could be strings instead, too. I suppose I could use a boost sparse matrix of some sort with integer keys, and it wouldn't matter if they're contiguous. Or would this still occupy a great deal of space, particularly if some genes have identifiers that are nine digits? Further, I am concerned that sparse storage is not appropriate, since this is an all-by-all matrix (there will be a distance in each and every cell, provided the gene exists). I'm unlikely to need to perform any matrix operations (e.g., matrix multiplication). I will need to pull vectors out of the matrix (slices). It seems like the best type of matrix would be keyed by a Boost unordered_map (a hash map), or perhaps even simply an STL map. Am I looking at this the wrong way? Do I really need to roll my own? I thought I saw such a class somewhere before. Thanks!

  • How do I get the XAML comiler to use textual content property on custom classes?

  • Index out of bounds exception while iterating through a List<string>.

    - by Sergio Tapia
    I have a List of the location of images on a folder. I have five pictureBoxes that emulate a coverflow type area for users to skim through the images of a given folder. I know that the error is fired because the first image in the collection is set to the first picturebox, then if I click on cycleLeft(), there is a negative number. How can I account for this? For example, if the first image in the List is already set to the farthest left and someone clicks flip left, have that first image put on the last position of the list. Any guidance? private void leftArrow_Click(object sender, EventArgs e) { cycleImagesLeft(); } private void rightArrow_Click(object sender, EventArgs e) { cycleImagesRight(); } public void cycleImagesLeft() { //imageThree is the center image, that's why I use it as a frame of reference. int currentImage = pictures.IndexOf(imageThree.ImageLocation); imageOne.ImageLocation = pictures[currentImage - 3]; imageTwo.ImageLocation = pictures[currentImage - 2]; imageThree.ImageLocation = pictures[currentImage - 1]; imageFour.ImageLocation = pictures[currentImage]; imageFive.ImageLocation = pictures[currentImage + 1]; } public void cycleImagesRight() { int currentImage = pictures.IndexOf(imageThree.ImageLocation); imageOne.ImageLocation = pictures[currentImage - 1]; imageTwo.ImageLocation = pictures[currentImage]; imageThree.ImageLocation = pictures[currentImage + 1]; imageFour.ImageLocation = pictures[currentImage + 2]; imageFive.ImageLocation = pictures[currentImage + 3]; }

  • XML strings in JAXB

    - by OOO
    I have a JPA entity class mimicking a table. Something like this: @XmlType(name="MyClassElementType") public class MyClass { String name; String xmlDesc; public MyClass() {} @XmlElement String getName() { return name; } void setName(String name) { this.name = name; } @XmlElement String getXmlDesc() { return xmlDesc; } void setXmlDesc(String xmlDesc) { this.xmlDesc = xmlDesc; } } In a Jersey REST get call I'm trying to return this class: @Get @Produces("application/xml") public MyClass get() { return myClass; } Now I'm expecting the already xml string(xmlStr) to be returned as is, but Jersey/JAXB escapes it... So anyway around this?

  • How can I split a Perl string only on the last occurrence of the separator?

    - by kiruthika
    Hi All, my $str="1:2:3:4:5"; my ($a,$b)=split(':',$str,2); In the above code I have used limit as 2 ,so $a will contain 1 and remaining elements will be in $b. Like this I want the last element should be in one variable and the elements prior to the last element should be in another variable. Example $str = "1:2:3:4:5" ; # $a should have "1:2:3:4" and $b should have "5" $str = "2:3:4:5:3:2:5:5:3:2" # $a should have "2:3:4:5:3:2:5:5:3" and $b should have "2"

  • How can I do a clean Mod_Rewrite that hides the variable numbers passed in the query string but just

I admire the way some developers do their mod_rewrite to produce something like: http://www.mycompany.com/accommodation/europe/ to run a substitute of "index.php?category_id=2&country=23" How can I achieve that in my urls?

  • How can I temporarily redirect printf output to a c-string?

    - by Ben S
    I'm writing an assignment which involves adding some functionality to PostgreSQL on a Solaris box. As part of the assignment, we need to print some information on the client side (i.e.: using elog.) PostgreSQL already has lots of helper methods which print out the required information, however, the helper methods are packed with hundreds of printf calls, and the elog method only works with c-style strings. Is there I way that I could temporarily redirect printf calls to a buffer so I could easily send it over elog to the client? If that's not possible, what would be the simplest way to modify the helper methods to end up with a buffer as output?

  • Is it necessary to "escape" character "<" and ">" for javascript string?

    - by Morgan Cheng
    Sometimes, server side will generate strings to be embedded in inline JavaScript code. For example, if "UserName" should be generated by ASP.NET. Then it looks like. <script> var username = "<%UserName%>"; </script> This is not safe, because a user can have his/her name to be </script><script>alert('bug')</script></script> It is XSS vulnerability. So, basically, the code should be: <script> var username = "<% JavascriptEncode(UserName)%>"; </script> What JavascriptEncode does is to add charater "\" before "/" and "'" and """. So, the output html is like. var username = "<\/scriptalert(\'bug\')<\/script<\/script"; Browser will not interpret "<\/script" as end of script block. So, XSS in avoided. However, there are still "<" and "" there. It is suggested to escape these two characters as well. First of all, I don't believe it is a good idea to change "<" to "&lt;" and "" to "&gt;" here. And, I'm not sure changing "<" to "\<" and "" to "\" is recognizable to all browsers. It seems it is not necessary to do further encoding for "<" and "". Is there any suggestion on this? Thanks.

  • Can't read query string if default index file name is omitted?

    - by Mike
    Is there an issue with IIS or ASP Classic where *Request.ServerVariables("QUERY_STRING")* returns blank if no default file name is given in the URL? On my local developer machine, I can do http://localhost/xslt/?opcs/abc which returns "opcs/abc". However, on our ancient web server, it returns nothing. I have to explicitly give it the default file name in the URL. Like so http://localhost/xslt/default.asp?opcs/abc While nothing too major, it is a little bit of a annoyance. One way I can maybe think of remidying the problem is have Javascript read the URL and return everything after the ?. Unfortunately, I do not know what version of IIS or ASP we are using. Thank you.
