  • I want just the insert query for a temp table.

    - by John Stephen
    Hi..I am using C#.Net and Sql Server ( Windows Application ). I had created a temporary table. When a button is clicked, temporary table (#tmp_emp_details) is created. I am having another button called "insert Values" and also 5 textboxes. The values that are entered in the textbox are used and whenever com.ExecuteNonQuery(); line comes, it throws an error message Invalid object name '#tbl_emp_answer'.. Below is the set of code.. Please give me a solution. Code for insert (in insert value button): private void btninsertvalues_Click(object sender, EventArgs e) { username = txtusername.Text; examloginid = txtexamloginid.Text; question = txtquestion.Text; answer = txtanswer.Text; useranswer = txtanswer.Text; SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=tempdb;Integrated Security=True;"); SqlCommand com = new SqlCommand("Insert into #tbl_emp_answer values('"+username+"','"+examloginid+"','"+question+"','"+answer+"','"+useranswer+"')", con); con.Open(); com.ExecuteNonQuery(); con.Close(); }

  • Why does grails use hsqldb when I ask for mysql?

    - by John
    I'm following the racetrack example from Jason Rudolph's book at InfoQ, using grails-1.2.1. I got up to the part where I was to switch from hsqldb to mysql. I think I've deleted every reference to hsqldb in the DataSource.groovy file, but I get an exception and the stack trace shows it's still using hsqldb. DataSource.groovy dataSource { boolean pooled = true String driverClassName = "com.mysql.jdbc.Driver" String url = "jdbc:mysql://localhost/dfpc2" String dbCreate = "create" String username = "dfpc2" String password = "dfpc2" dialect = org.hibernate.dialect.MySQL5InnoDBDialect } hibernate { cache.use_second_level_cache=true cache.use_query_cache=true cache.provider_class='net.sf.ehcache.hibernate.EhCacheProvider' } // environment specific settings environments { development { } test { } production { } } When I grails run-app it all starts up with no errors. I can navigate to the home page. But when I click on one of the links, I get a stack trace: java.sql.SQLException: Table not found in statement [select this_.id as id0_0_, this_.version as version0_0_, this_.name as name0_0_, this_.variant as variant0_0_ from domainObject this_ limit ?] at org.hsqldb.jdbc.Util.throwError(Unknown Source) at org.hsqldb.jdbc.jdbcPreparedStatement.<init>(Unknown Source) at org.hsqldb.jdbc.jdbcConnection.prepareStatement(Unknown Source) at dfpc2.domainObjectController$_closure2.doCall(script1269434425504953491149.groovy:13) at dfpc2.domainObjectController$_closure2.doCall(script1269434425504953491149.groovy) at java.lang.Thread.run(Thread.java:619) My mysql database shows no tables created. (I don't think groovy's connected to mysql yet.) Things I've checked: mysql-connector-java-5.1.6.jar is in lib directory. I've tried grails clean I tried putting the dataSource info in the development environment (I haven't graduated to test or prod yet), but it seemed to make no difference. The stdout shows I'm using development env. I've googled for solutions, but the only solution I've found is when people don't change the test or production environments.

  • Is it good practice to name variables differently when defining more than one function?

    - by John
    For example, in this simple function where fun1 takes as input two numbers, adds them together and passes them to function 2 for printing the output. var1_in is local to each function, so is it OK to use the name var1_in in both functions, or is it better practice to call them different things? fun1 <- function (var1_in, var2_in) { var3 = var1_in + var2_in fun2(var3) } fun2 <- function (var1_in) { var4 = var1_in print(var4) }

  • Any way to make dialogs appear/disappear with a transition in MFC?

    - by John
    For instance I have a main dialog, when I click a button a smaller dialog appears next to it. But it would be neat if the small one could somehow transition in, rather than simply appear. For instance using transparency, or zooming in, or sliding in from width=0 - full-width. Making an actual dialog do such things isn't too hard, but what about the controls within it? How might we approach this in a way that is reusable on different dialogs?

  • WPF: How to efficiently update an Image 30 times per second

    - by John
    Hello, I'm writing a WPF application that uses a component, and this component returns a pointer (IntPtr) to pixels of a bitmap (stride * height). I know in advance that the bitmap is a 24bits rgb, its width and height. Updating the Image control with these bitmaps makes up a video to the user, but I'm not sure what's the most efficient way to do that, most of the time the CPU usage goes to 75%+ and memory changing from 40mb to 500mb and the nI think GC starts to work and then it drops again to 40mm. The app starts to not be responsive. What shoud I do? thanks!

  • Django display manytomany field in form when definition is on other model

    - by John
    Hi I have the definition for my manytomany relationship on one model but want to display the field on the form of my other model. How do I do this? for example: # classes class modelA(models.Model): name = models.CharField(max_length=300) manytomany = models.ManyToManyField(modelA) class modelB(models.Model): name = models.CharField(max_length=300) # forms class modelBForm(forms.ModelForm): class Meta: model = modelB If I then used modelBForm it would show a select box with the models from modelA rather than just name. Thanks

  • using 'or' operator not working for menu

    - by John Wilkes
    In my code here, I have a CSS class called "active" which I use if the $_GET['page'] == tutorials, php, mysql, etc... The problem is, even if the 'page' variable is not equal to any of these values, the Tutorials button in this case is still active for some reason. Any ideas why this would be happening? Am I using the 'or' (||) operand incorrectly? <?php if($_GET['page'] == 'tutorials' || 'php' || 'mysql' || 'html' || 'css' || 'js') { ?> <li class="active"> <?php } else { ?> <li> <?php } ?> <a href="index.php?page=tutorials">Tutorials</a> <ul> <li><a href="index.php?page=php">PHP</a></li> <li><a href="index.php?page=mysql">MySQL</a></li> <li><a href="index.php?page=html">HTML</a></li> <li><a href="index.php?page=css">CSS</a></li> <li><a href="index.php?page=js">JS</a></li> </ul> </li>

  • getcwd for current location based on ftp account permission

    - by John Doe
    Hello. I'm trying to make a small script that's changing the permission for specific file using a ftp connection. My problem is the absolute path. I have a ftp account wich land on the script directory (/script/). If i'm using getcwd, it will return the whole path (/home/user/public_html/script) but i need only the difference between the full path and the current path (getcwd path: /home/user/public_html/script/ ftp landing path: /script). So, how can i use getcwd to get the current directory for a ftp account? For example, if the user is landing in public_html, the path to the script will be /script/, or if he is landing inside /user, the path will be /public_html/script. Thanks

  • Need to tab out of ActiveX control in browser

    - by John Donoghue
    When tabbing through controls in an ActiveX control hosted in IE, once I get to the last control the tab key no longer does anything. I would like it to move the focus outside the ActiveX control to the next html control. This works fine when the ActiveX control is hosted in a WinForms app, does anybody know how to make this work in the browser? It may also be relevant that the ActiveX control is a simple wrapper around a WPF control.

  • Servlet response wrapper has encoding problem

    - by John O
    A servlet response wrapper is being used in a Servlet Filter. The idea is that the response is manipulated, with a 'nonce' value being injected into forms, as part of defence against CSRF attacks. The web app is using UTF-8 everywhere. When the Servlet Filter is absent, no problems. When the filter is added, encoding issues occur. (It seems as if the response is reverting to 8859-1.) The guts of the code : final class CsrfResponseWrapper extends AbstractResponseWrapper { ... byte[] modifyResponse(byte[] aInputResponse){ ... String originalInput = new String(aInputResponse, encoding); String modifiedResult = addHiddenParamToPostedForms(originalInput); result = modifiedResult.getBytes(encoding); ... } ... } As I understand it, the transition between byte-land and String-land should specify an encoding. That is done here, as you can see, in two places. The value of the 'encoding' variable is 'UTF-8'; the alteration of the String itself is standard string manipulation (with a regex), and never specifies an encoding (addHiddenParamToPostedForms). Where am I in error about the encoding? EDIT: Here is the base class (sorry it's rather long): package hirondelle.web4j.security; import javax.servlet.ServletOutputStream; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpServletResponseWrapper; import java.io.ByteArrayOutputStream; import java.io.IOException; import java.io.PrintWriter; /** Abstract Base Class for altering response content. (May be useful in future contexts as well. For now, keep package-private.) */ abstract class AbstractResponseWrapper extends HttpServletResponseWrapper { AbstractResponseWrapper(ServletResponse aServletResponse) throws IOException { super((HttpServletResponse)aServletResponse); fOutputStream = new ModifiedOutputStream(aServletResponse.getOutputStream()); fWriter = new PrintWriter(fOutputStream); } /** Return the modified response. */ abstract byte[] modifyResponse(byte[] aInputResponse); /** Standard servlet method. */ public final ServletOutputStream getOutputStream() { //fLogger.fine("Modified Response : Getting output stream."); if ( fWriterReturned ) { throw new IllegalStateException(); } fOutputStreamReturned = true; return fOutputStream; } /** Standard servlet method. */ public final PrintWriter getWriter() { //fLogger.fine("Modified Response : Getting writer."); if ( fOutputStreamReturned ) { throw new IllegalStateException(); } fWriterReturned = true; return fWriter; } // PRIVATE /* Well-behaved servlets return either an OutputStream or a PrintWriter, but not both. */ private PrintWriter fWriter; private ModifiedOutputStream fOutputStream; /* These items are used to implement conformance to the javadoc for ServletResponse, regarding exceptions being thrown. */ private boolean fWriterReturned; private boolean fOutputStreamReturned; /** Modified low level output stream. */ private class ModifiedOutputStream extends ServletOutputStream { public ModifiedOutputStream(ServletOutputStream aOutputStream) { fServletOutputStream = aOutputStream; fBuffer = new ByteArrayOutputStream(); } /** Must be implemented to make this class concrete. */ public void write(int aByte) { fBuffer.write(aByte); } public void close() throws IOException { if ( !fIsClosed ){ processStream(); fServletOutputStream.close(); fIsClosed = true; } } public void flush() throws IOException { if ( fBuffer.size() != 0 ){ if ( !fIsClosed ) { processStream(); fBuffer = new ByteArrayOutputStream(); } } } /** Perform the core processing, by calling the abstract method. */ public void processStream() throws IOException { fServletOutputStream.write(modifyResponse(fBuffer.toByteArray())); fServletOutputStream.flush(); } // PRIVATE // private ServletOutputStream fServletOutputStream; private ByteArrayOutputStream fBuffer; /** Tracks if this stream has been closed. */ private boolean fIsClosed = false; } }

  • Use HTTP PUT to create new cache (ehCache) running on the same Tomcat?

    - by socal_javaguy
    I am trying to send a HTTP PUT (in order to create a new cache and populate it with my generated JSON) to ehCache using my webservice which is on the same local tomcat instance. Am new to RESTful Web Services and am using JDK 1.6, Tomcat 7, ehCache, and JSON. I have my POJOs defined like this: Person POJO: import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class Person { private String firstName; private String lastName; private List<House> houses; // Getters & Setters } House POJO: import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class House { private String address; private String city; private String state; // Getters & Setters } Using a PersonUtil class, I hardcoded the POJOs as follows: public class PersonUtil { public static Person getPerson() { Person person = new Person(); person.setFirstName("John"); person.setLastName("Doe"); List<House> houses = new ArrayList<House>(); House house = new House(); house.setAddress("1234 Elm Street"); house.setCity("Anytown"); house.setState("Maine"); houses.add(house); person.setHouses(houses); return person; } } Am able to create a JSON response per a GET request: @Path("") public class MyWebService{ @GET @Produces(MediaType.APPLICATION_JSON) public Person getPerson() { return PersonUtil.getPerson(); } } When deploying the war to tomcat and pointing the browser to http://localhost:8080/personservice/ Generated JSON: { "firstName" : "John", "lastName" : "Doe", "houses": [ { "address" : "1234 Elmstreet", "city" : "Anytown", "state" : "Maine" } ] } So far, so good, however, I have a different app which is running on the same tomcat instance (and has support for REST): http://localhost:8080/ehcache/rest/ While tomcat is running, I can issue a PUT like this: echo "Hello World" | curl -S -T - http://localhost:8080/ehcache/rest/hello/1 When I "GET" it like this: curl http://localhost:8080/ehcache/rest/hello/1 Will yield: Hello World What I need to do is create a POST which will put my entire Person generated JSON and create a new cache: http://localhost:8080/ehcache/rest/person And when I do a "GET" on this previous URL, it should look like this: { "firstName" : "John", "lastName" : "Doe", "houses": [ { "address" : "1234 Elmstreet", "city" : "Anytown", "state" : "Maine" } ] } So, far, this is what my PUT looks like: @PUT @Path("/ehcache/rest/person") @Produces(MediaType.APPLICATION_JSON) @Consumes(MediaType.APPLICATION_JSON) public Response createCache() { ResponseBuilder response = Response.ok(PersonUtil.getPerson(), MediaType.APPLICATION_JSON); return response.build(); } Question(s): (1) Is this the correct way to write the PUT? (2) What should I write inside the createCache() method to have it PUT my generated JSON into: http://localhost:8080/ehcache/rest/person (3) What would the command line CURL comment look like to use the PUT? Thanks for taking the time to read this...

  • How do you have grayed out text in a textfield that dissapears when the user clicks on it

    - by John Smith
    In HTML & JS, how do you make a textfield that has grayed out text telling the user what the field is for that goes away when the user clicks on the field? For example, in firefox the search field in the top right hand side says which search engine it uses when there's nothing entered, then once you click it's an empty textfield, but if you leave it blank and remove focus from the textfield then the grayed out text is back again. Is there a name for this behavior? Also, is it possible to do in pure css without the use of js to do the on focus / on blur events?

  • When to delete newly deprecated code?

    - by John
    I spent a month writing an elaborate payment system that handles both credit card payments and electronic fund transfers. My work was used on production server for about a month. I was told recently by the client that he no longer wants to use the electronic fund transfer feature. Because the way I had to interface and communicate with the credit card gateway is drastically different from the electronic fund transfer api (eg. the cc company gives transaction responses immediately after an http request, while the eft company gives transaction responses 5 business days after an http request), I spent a lot of time writing my own API to abstract common function calls like function payment(amount, pay_method,pay_freq) function updateRecurringSchedule(user_id,new_schedule) etc.. Now that the client wants to abandon the EFT feature, all my work for this abstracted payments API is obsolete. I'm deliberating over whether I should scrap my work. Here's my pro vs. con for scrapping it now: PRO 1: Eliminate code bloat PRO 2: New developers do not need to learn MY API. They only need to read the CC company's API PRO 3: Because the EFT company did not handle recurring payment schedules, refunds, and validation, I wrote my own application to do it. Although the CC company's API permitted this functionality, I opted to use mine instead so that I could streamline my code. now that EFT is out of the picture, I can delete all this confusing code and just rely on the CC company's sytsem to manage recurring billing, payment schedules, refunds, validations etc... CON 1: Although I can just delete the EFT code, it still takes time to remove the entire framework consolidates different payment systems. CON 2: with regards to PRO 3, it takes time to build functionality that integrates the payment system more closely with the CC company. CON 3: I feel insecure deleting all this work. I don't think I'll ever use it again. But, for some inexplicable reason, I just don't feel comfortable deleting this work "right now". So my question is, should I delete one month's worth recent development? If yes, should I do it immediately or wait X amount of time before doing so?

  • Thoughts on streamlining multiple .Net apps

    - by John Virgolino
    We have a series of ASP.Net applications that have been written over the course of 8 years. Mostly in the first 3-4 years. They have been running quite well with little maintenance, but new functionality is being requested and we are running into IDE and platform issues. The apps were written in .Net 1.x and 2.x and run in separate spaces but are presented as a single suite of applications which use a common navigation toolbar (implemented as a user control). Every time we want to add something to a menu in the nav we have to modify it in all the apps which is a pain. Also, the various versions of Crystal reports and that we used tables to organize the visual elements and we end up with a mess, especially with all the multi-platform .Net versions running. We need to streamline the suite of apps and make it easier to add on new apps without a hassle. We also need to bring all these apps under one .Net platform and IDE. In addition, there is a WordPress blog styled to match the style of the application suite "integrated" into the UI and a link to a MediaWiki Wiki application as well. My current thinking is to use an open source content management system (CMS) like Joomla (PHP based unfortunately, but it works well) as the user interface framework for style templating and menu management. Joomla's article management would allow us to migrate the Wiki content into articles which could be published without interfering with the .Net apps. Then essentially use an IFrame within an "article" to "host" the .Net application, then... Upgrade the .Net apps to VS2010, strip out all the common header/footer controls and migrate the styles to use the style sheets used in the CMS. As I write this, I certainly realize this is a lot of work and there are optimization issues which this may cause as well as using IFrames seems a bit like cheating and I've read about issues with IFrames. I know that we could use .Net application styling, but it seems like a lot more work (not sure really). Also, the use of a CMS to handle the blog and wiki also seems appealing, unless there is a .Net CMS out there that can handle all of these requirements. Given this information, I am looking to know if I am totally going in the wrong direction? We tried to use open source and integrate it over time, but not this has become hard to maintain. Am I not aware of some technology out there that will meet our requirements? Did we do this right and should we just focus on getting the .Net streamlined? I understand that no matter what we do, it's going to be a lot of work. The communities considerable experience would be helpful. Thanks!! PS - A complete rewrite is not an option.

  • MySQL Math - Is it possible to calculate a correlation in a query?

    - by John M
    In a MySQL (5.1) database table there is data that represents: how long a user takes to perform a task and how many items the user handled during the task. Would MySQL support correlating the data or do I need to use PHP/C# to calcuate? Where would I find a good formula to calculate correlation (it's been a long time since I last did this)?

  • Planning and coping with deadlines in SCRUM

    - by John
    From wikipedia: During each “sprint”, typically a two to four week period (with the length being decided by the team), the team creates a potentially shippable product increment (for example, working and tested software). The set of features that go into a sprint come from the product “backlog,” which is a prioritized set of high level requirements of work to be done. Which backlog items go into the sprint is determined during the sprint planning meeting. During this meeting, the Product Owner informs the team of the items in the product backlog that he or she wants completed. The team then determines how much of this they can commit to complete during the next sprint. During a sprint, no one is allowed to change the sprint backlog, which means that the requirements are frozen for that sprint. After a sprint is completed, the team demonstrates the use of the software. I was reading this and two questions immediately popped into my head: 1)If a sprint is only a couple of weeks, decided in a single meeting, how can you accurately plan what can be achieved? High-level tasks can't be estimated accurately in my experience, and can easily double what seems reasonable. As a developer, I hate being pushed into committing what I can deliver in the next month based on a set of customer requirements, this goes against everything I know about generating reliable estimates rather than having to roughly estimate and then double it! 2)Since the requirements are supposed to be locked and a deliverable product available at the end, what happens when something does take twice as long? What if this feature is only 1/2 done at the end of the sprint? The wiki article goes on to talk about Sprint planning, where things are broken down into much smaller tasks for estimation (<1 day) but this is after the Sprint features are already planned and the release agreed, isn't it? kind of like a salesman promising something without consulting the developers.

    Hi, I am new to the Dojo Toolkit. I'm getting the error Tried to register widget with id=myButton but that id is already registered whenever I try to load dojo content twice (meaning I load HTML content through jQuery.Load into a container div). Is there a way of unregistering already registered widgets in dojo? I've seen some examples, but I don't really get them working. My button: <button dojoType="dijit.form.Button" id="myButton">button</button>
