• Java Sql Udate error, data type missmatch

  - by codo

  I have created a table in ms access. I have set the data type of ID to Auto Number in MS-access. In java when I try to update a record. the netBeans IDE gives me the error of " data type missmatch in criteria expression". But when I changed the ID number that was not in the table already it works well. The code is below. String sql = "Update table1 set price ='" + txtPrice.getText() + "', quantity='" + txtQuantity.getText() + "', description='" + txtDescription.getText() + "' where id= " + txtid.getText() + ""; try { pst = conn.prepareStatement(sql); pst.executeUpdate(); JOptionPane.showMessageDialog(null, "Updated"); UpdateJTable(); } catch (Exception e) { JOptionPane.showMessageDialog(null, e); }

• Tune cindent "switch" indentation

  - by Don Reba

  Nemerle is a C-like language and mostly works very well with cindent. However, its construct analogous to switch is called match: match (x) { | "Hello World" => ... | _ => ... } Is it possible to get the cinoptions for switch statements to apply to this construct, instead? Maybe there is a regular expression I can set somewhere. If not, can I get the vertical bars to align with the braces another way?

• Access SQL query to SELECT from one table and INSERT into another

  - by typoknig

  Below is my query. Access does not like it, giving me the error Syntax error (missing operator) in query expression 'answer WHERE question = 1'. Hopefully you can see what I am trying to do. Please pay particular attention to 3rd, 4th, and 5th lines under the SELECT statement. INSERT INTO Table2 (respondent,1,2,3-1,3-2,3-3,4,5) SELECT respondent, answer WHERE question = 1, answer WHERE question = 2, answer WHERE answer = 'text 1' AND question = 3, answer WHERE answer = 'text 2' AND question = 3, answer WHERE answer = 'text 3' AND question = 3, answer WHERE question = 4, longanswer WHERE question 5 FROM Table1 GROUP BY respondent;

• Get name and value from the input tag

  - by DroidIn.net

  Before you say "oh no, not again" here I'm stating my case. I'm parsing part of HTML output and the only thing I'm interested in is name and value attributes of each <input/ tag. HTML is actually HTML fragment, may not be well-formed. I don't have DOM or HTML parser and I don't try to parse nested elements anyway. The problem is that I don't know the order or number of attributes so it could be <input name="foo" value="boo"/> or <input type="hidden" name=foo> or <input id=blah value='boo' src="image.png" name="foo" type="img"/>. Is there a single regular expression that would get me values of name and value attribute in predictable order? I wouldn't have asked the question if I could assume that name attribute always precedes value but unfortunately this is not the case

• Java splitting string by custom regex match

  - by slikz

  I am completely new to regular expressions so I'm looking for a bit of help here. I am compiling under JDK 1.5 Take this line as an example that I read from standard input: ab:Some string po:bubblegum What I would like to do is split by the two characters and colon. That is, once the line is split and put into a string array, these should be the terms: ab:Some string po:bubblegum I have this regex right now: String[] split = input.split("[..:]"); This splits at the semicolon; what I would like is for it to match two characters and a semicolon, but split at the space before that starts. Is this even possible? Here is the output from the string array: ab Some String po bubblegum I've read about Pattern.compile() as well. Is this something I should be considering?

• How to represent datetime of different time zomes in C#

  - by Mohoch

  I have a .NET WebService (written in C#), that is supposed to serve people around the world. With each request I get the user's datetime in his own time zone with the format : yyyy/MM/dd HH:mm ZZZZ. I have to convert the string to something representing the original date and time and specifying the time zone in GMT. I have to make some logical calculations and keep it in the database. The regular DateTime doe's not support this. it does not have a property specifying the time zone. When I try to convert my string into DateTime - it simply converts it to my local time. I do not want to keep my time in UTC, because I have some logic that has to run per user by his own time. Does anyone know a C# class that handles this?

• C input loop for shell

  - by AustinM

  So I'm working on creating a very simple C program that just preforms shell commands. This is what I have so far: #include <stdio.h> int main() { char input[30]; fputs("$ ", stdout); fflush(stdout); fgets(input, sizeof input, stdin); system(input); } It works, but only for one command. For example if I compile and type ./cmd I get the $ prompt. If I type ls I get what I'm supposed to get. But then it exits and goes back to the regular system shell. How can I make it so after the user types a command it goes back to the "$" input.

• Is possible to set generic type by another class?

  - by Soul_Master

  I use ASP.NET MVC for serving web application and I want to create something like the following code. <% using(HTML.Form(Model)) { %> <% HTML.CreateTextBox('txt1', x => x.Property1); <% } From the above code, Form extension method will receive object that represent type of current Model object in current View page. Next, CreateTextBox method will receive type from Form method and I can bind textbox to some property of this model. Update 1 The following code is code of CreateTextBox method that will create instance of TextBox class. public static CreateTextBox(string value, Expression<Func<object>> bindedProperty) { // T should be receive from HTML.Form method or class return new TextBox<T>(value); } Is it possible to creating some code that doing something like the above code? Thanks,

• ASP MVC html helpers in partial views

  - by Rabbi

  I am still trying to figure out how to create reusable partial views in MVC Lets say I would like to create a partial view to display a form for submitting an address. Then in my ViewModel I have two addresses (Home address & Work Address) So I would think that in my view I call HTML.Partial for each one like this @Html.Partial("Address", Model.HomeAddress) @Html.Partial("Address", Model.WorkAddress) but what happens is instead of the fields having names like HomeAddress.Street, HomeAddress.City etc. they just have the regular field names Street, City, etc. so the binder on the HTTPPost action has no idea what to do with them Thanks in advance

• Finding center of fingerprints.

  - by an_ant

  If we suppose that every fingerprint is made of concentric curves (ellipses or circles) - and I'm aware of the fact that not every fingerprint is - how can I find center of those concentric curves? Let's take this "ideal" fingerprint and try to find out its center ... My approaches were to try: Find the spectrum through columns/rows of the image and try to find columns/rows that maximize particular band of the spectrum. I thought that column going through the center would have most regular pattern of changing amplitudes - therefore, most recognizible harmonic. My second approach was to try to count the changes of black-and-white also through the columns and rows, and to maximize that amount among rows and columns also. While these methods work to the some extant, with some additional filtering, they fail, when fingerprint is "not ideal as this one is". Can you think of any different approach? Are there standard ways to do it?

• Java or C# + XNA for some simple animations?

  - by lala

  I want to make a program that will involve some faces with various facial expressions. They will change from one facial expression to another based on their "mood" as influenced by user input. I know some java but I have done pretty much nothing with graphics. A friend tells me that it will be easier to do this in C# with XNA than to do it in java. I have about a month to do this, so I was hoping you folks would help me make a decision. Would I be better off figuring out how to do this in java, or learning C# and XNA and doing it in C#? Is it so much easier to do this in C# that it would be quicker to learn C# than to struggle with doing it in java? Will it probably come out looking much better if it is in C#?

• Ho do I extract a Outlook message nested into another using Apache POI - HSMF?

  - by Jan

  I am using Apache POI - HSMF to extract attachments from Outlooks msg-files. It works fine except for nested messages. If an msg is attached to another msg I am able to get the files. If a message is nested I get the information but I need the file. MAPIMessage msg = new MAPIMessage(fileName) for(AttachmentChunks attachment : msg.getAttachmentFiles()) { if(attachment.attachmentDirectory!=null){ MAPIMessage nestedMsg attachment.attachmentDirectory.getAsEmbededMessage(); // now save nestedMsg as a msg-file } } Is it possible to save the nested message file as a regular msg-file?

• Ruby: map tags into a boolean condition to get a true/false result

  - by cgyDeveloper

  I have an array of tags per item like so: item1 = ['new', 'expensive'] item2 = ['expensive', 'lame'] I also have a boolean expression as a string based on possible tags: buy_it = "(new || expensive) && !lame" How can I determine if an item matches the buying criteria based on the tags associated with it? My original thought was to do a gsub on all words in buy_it to become 'true' or 'false' based on them existing in the itemx tags array and then exec the resulting string to get a boolean result. But since the Ruby community is usually more creative than me, is there a better solution?

• Replace html tag with a certain class

  - by fire

  I am looking for suitable replacement code that allows me replace the content inside of any HTML tag that has a certain class e.g. $class = "blah"; $content = "new content"; $html = '<div class="blah">hello world</div>'; // code to replace, $html now looks like: // <div class="blah">new content</div> Bare in mind that: It wont necessarily be a div, it could be <h2 class="blah"> The class can have more than one class and still needs to be replaced e.g. <div class="foo blah green">hello world</div> I am thinking regular expressions should be able to do this, if not I am open to other suggestions such as using the DOM class (although I would rather avoid this if possible because it has to be PHP4 compatible).

• (.*) instead of (.*?)

  - by EBAGHAKI

  Suppose we have this html content, and we are willing to get Content1, Content2,.. with regular expression. <li>Content1</li> <li>Content2</li> <li>Content3</li> <li>Content4</li> If I use the line below preg_match_all('/<li>(.*)<\/li>/', $text, $result); i will get an array with a single row containing: Content1</li> <li>Content2</li> <li>Content3</li> <li>Content4 And by using this code: preg_match_all('/<li>(.*?)<\/li>/', $text, $result); i will get an array with 4 row containing Content1, Content2, ... Why (.*) is not working since it means match any character zero or more times

• Interesting or unique types encountered?

  - by user318904

  What is the most strange or unique type you have seen in a programming language? I was thinking the other day about a "random variable", ie whenever it is evaluated it yields a random value from some domain. It would require some runtime trickery. Also I bet there can be some interesting mapping of regular expressions into a type system. It does not necessarily have to be a built in or primitive type, but some random class that implements a domain specific type won't really be interesting just unique.

• Why is my regex so much slower compiled than interpreted ?

  - by miket2e

  I have a large and complex C# regex that runs OK when interpreted, but is a bit slow. I'm trying to speed this up by setting RegexOptions.Compiled, and this seems to take about 30 seconds for the first time and instantly after that. I'm trying to negate this by compiling the regex to an assembly first, so my app can be as fast as possible. My problem is when the compiling delay takes place: Regex myComplexRegex = new Regex(regexText, RegexOptions.Compiled); MatchCollection matches = myComplexRegex.Matches(searchText); foreach (Match match in matches) // <--- when the one-time long delay kicks in { } This is making compiling to an assembly basically useless, as I still get the delay on the first foreach call. What I want is for all the compiling delay to be done in advance when I compile to the assembly, not when the user runs the app. Where am I going wrong ? (The code I'm using to compile to an assembly is similar to http://www.dijksterhuis.org/regular-expressions-advanced/ , if that's relevant ).

• Bind web user control property in markup

  - by Ian Levy

  I'm sure it's elementary but I can't figure it out. This does not work - the the binding expression is passed as string to the control: {<uc:usercontrol runtat="server" message='<%#Me.protectedVariable%>'/>} The code behind include a Page.Databind() call in page_load. But this does work: <uc:usercontrol runat="server" id="usercontrol1"/> And in code behind page_load: usercontrol1.message = Me.protectedVariable Do I have to bind from the code-behind? Is this a page life cycle issue?

• Type signature "Maybe a" doesn't like "Just [Event]"

  - by sisif

  I'm still learning Haskell and need help with the type inference please! Using packages SDL and Yampa I get the following type signature from FRP.Yampa.reactimate: (Bool -> IO (DTime, Maybe a)) and I want to use it for: myInput :: Bool -> IO (DTime, Maybe [SDL.Event]) myInput isBlocking = do event <- SDL.pollEvent return (1, Just [event]) ... reactimate myInit myInput myOutput mySF but it says Couldn't match expected type `()' against inferred type `[SDL.Event]' Expected type: IO (DTime, Maybe ()) Inferred type: IO (DTime, Maybe [SDL.Event]) In the second argument of `reactimate', namely `input' In the expression: reactimate initialize input output process I thought Maybe a allows me to use anything, even a SDL.Event list? Why is it expecting Maybe () when the type signature is actually Maybe a? Why does it want an empty tuple, or a function taking no arguments, or what is () supposed to be?

• HTACCESS redirection with a word replacement in url

  - by Marwen

  I'm having trouble with this reg expression which i belive is correct, but it is not working. What im trying to do is redirect bunch of urls containing a specific string like this: http://www.example.com/**undesired-string**_another-string to http://www.example.com/**new-string**_another-string and http://www.example.com/folder/**undesired-string**/another-string to http://www.example.com/folder/**new-string**/another-string So i have this code in the .htaccess: <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule (.+)+(undesired-string)+(.+) $1new-string$2 [R=301,L] </IfModule> This should replace ANY undesired-string in any url to new-string, but it is not working, any idea why ? Thank you

• Pulling international street addresses / phone numbers from free-form text

  - by spitzanator

  Hey, folks. I'm looking for some regular expressions to help grab street addresses and phone numbers from free-form text (a la Gmail). Given some text: "John, I went to the store today, and it was awesome! Did you hear that they moved to 500 Green St.? ... Give me a call at +14252425424 when you get a chance." I'd like to be able to pull out: 500 Green St. (recognized as a street address) +14252425424 (recognized as a phone number) What makes this problem easier is that I don't care about parsing text that gets pulled out. That is, I don't care that Green is the name of the road or that 425 is the area code. I just want to grab strings that "look like" addresses or telephone numbers. Unfortunately, this needs to work internationally, as best as possible. Anyone have any leads? Thanks!

• Replacing the end of the line by SED in makefile

  - by Masi

  How can you append to the end of a line by SED controlled by makefile? I run paste -d" " t.tex tE.tex | sed 's@$@XXX@' > tM.tex where the problem is in the use of the mark $ for the end of the line. I get #paste -d" " t.tex tE.tex | sed -e s/" "/\\\&/g | sed -r "s/XXX/" > tM.tex sed: -e expression #1, char 10: unterminated `s' command make: *** [all] Error 1 I have the command just after the "all:" tag in my makefile which contains only the two lines. The parameters -n and -e do not help here. The command works as expected run when it is run directly in terminal.

• viewForHeaderInSection - create header that would display properly in all cases

  - by sha

  I have an interesting problem/question and i'm not sure if it is even doable. So I have a custom header view for regular UITableView. But it's transparent and it doesn't fill fill table width. So it displayed properly when table is scrolled and this header view is displayed above cell content (sticked to the top). But when same header is displayed between two sections down - it looks ugly, because it's transparent and it's either displayed above black rectangle or above table background. I was wondering is there way to customize header view for when it's stick to the top and when it's not. Or... may be it's possible to specify what needs to be displayed underneath header view when it's between sections. Something like sectionSeparatorView?
