  • Confused about distinct/aggregate queries with (N)Hibernate

    - by nw
    I'm not sure how to approach queries that don't map 1:1 to my persistent entities - in other words, distinct and aggregate queries. For example, I need to retrieve a distinct list of property values for populating a drop-down list. Should I write a class and a mapping for the "entities" that are returned by this query? Or should I just use the native DB provider and work with native data sets instead?

  • Dreaded iframe horizontal scroll bar can't be removed in IE?

    - by mrjrdnthms
    I have an iframe. The content is wider than the width I am setting so the iframe gets a horizontal scroll bar. I can't increase the width of the iframe so I want to just remove the scroll bar. I tried setting the scroll property to "no" but that kills both scroll bars and I want the vertical one. I tried setting overflow-x to "hidden" and that killed the horizontal scroll bar in ff but not in IE. sad for me.

  • .split("1px") into ["1px",1,"px"] in Javascript

    - by Jay
    I'm rubbish at Regular Expressions, really! What I'd like is to split a string containing a CCS property value into an array of [string,value,unit]. For example: if I supplied the .split() method with 1px it'd return ["1px",1,"px"]. If I were to supply, similarly, 10% it'd return ["10%",10,"%"]. Can this be done? I appreciate all your help!

  • There's @interface in my @implementation — why is that?

    - by Mark McDonald
    This is a pretty noobish question – I'm looking at some Cocoa sample code and there's @interface blocks in the .m files as well as the headers. For instance, in the AppDelegate class header, a UIWindow and UI navigation are defined as instance variables, but the @property declarations are actually made in the implementation file. Is there a functional reason for this, is it a stylistic choice, or… ?

  • When to Use Properties & When to Use Methods?

    - by DaveDev
    Hi Guys I was looking at the following line of code foreach (PropertyInfo prop in t.GetProperties()) and I noticed that tprovides a method to return the type's properties instead of a property like t.Properties This makes me wonder why sometimes people use properties to make a type's data avilable and other times there's a method provided? Is there some logic behind the decision? Thanks Dave

  • Codeigniter : database configuration

    - by nppCods
    I am beginner for CI so don’t have good knowledge. My problem is: I am not using any database. All the records are fetched from JSON. Therefore I don’t think I need to configure database… As said by CI, it doesn’t necessarily ask for database. So my database.php configuration is : $active_group = ‘default’; $active_record = FALSE; $db[‘default’][‘hostname’] = ‘’; $db[‘default’][‘username’] = ‘’; $db[‘default’][‘password’] = ‘’; $db[‘default’][‘database’] = ‘’; $db[‘default’][‘dbdriver’] = ‘mysql’; $db[‘default’][‘dbprefix’] = ‘’; $db[‘default’][‘pconnect’] = TRUE; $db[‘default’][‘db_debug’] = TRUE; $db[‘default’][‘cache_on’] = FALSE; $db[‘default’][‘cachedir’] = ‘’; $db[‘default’][‘char_set’] = ‘utf8’; $db[‘default’][‘dbcollat’] = ‘utf8_general_ci’; $db[‘default’][‘swap_pre’] = ‘’; $db[‘default’][‘autoinit’] = TRUE; $db[‘default’][‘stricton’] = FALSE; It works in my local system but doesn’t work in live server. I am so surprised. Then I provided hostname, username, password and dbdriver, it works. My question is that, is that necessary to provide all the details if I am not using database? Thank you for your suggestion.

  • How do I stop the designer from filling in my properties with null values?

    - by Tim Gradwell
    When I add a control to a form, visual studio assigns various of the properties of that form a value of null in the auto-generated designer code. I don't want the designer to make the redundant assignment (the value is already null). Can anyone tell me how to prevent it? example MyControl has property public SomeClass MyProperty { get { return m_MyValue; } set { m_MyValue = value; } } designer then autogenerates the following: myControl1.MyProperty = null;

  • How to determine when the text of an html element is changed

    - by Micah
    I have an error message like this: <span class="errorMessage">Your input sucks!</span> and I need to determine when it changes. the validation framework I'm using sets the text when there's an error and removes it when it's complete. I'm hoping to tap into that by watching for changes to the text property of the element using jquery. Any idea of how to go about doing this? Thanks!

  • Access "currentState" from other classes?

    - by Herter
    I'm making a little application in Actionscript 3. In my initApp.as I have created another class which needs to edit the currentState, which is only accessible from the main .as (initApp.as). I found a solution such that I can reach the currentState property from my other class: Application.application.currentState. This is however not a good solution as it couples the classes too much.. is there a better way of editing the currentState from other classes?

  • DBTransaction Rollback throws

    - by pdiddy
    Looking into the documentation it says that the Rollback method can throw when the transaction is not in pending state (after begin transaction and before commit transaction). I can't seem to find a way to check whether the transaction can be rollback or not. There isn't a state property either.

A few other requirements supports blocking (I can't use non-blocking/nio) isn't set as an environment or some other global scope property (there are multiple threads accessing) I was looking into HttpCore components but I did not see any support for blocking https.

  • .NET & Worflow, SqlTrackingQuery.GetWorkflows() on wire correct - presented object not

    - by UKShots
    With windows workflow when using the tracking service, the SqlTrackingQuery.GetWorkflows() method returns correctly the workflow type and assembly version on the wire from the DB query - but when one comes to query the returned SqlTrackingWorkflowInstance object it's WorkflowType.AssemblyQualifiedName property is returned as the current assembly version of the workflow type (i.e. it looks to matching on FQ type name only and not version). Anyone know how to get to the actual returned data (other than either a custom query or hook)?

  • php: avoiding __get in certain circumstances?

    - by user151841
    I have a class where I'm using __set. Because I don't want it to set just anything, I have an array of approved variables that it checks before it will actually set a class property. However, on construct, I want the __construct method to set several class properties, some of which are not in the approved list. So when construct happens, and I do $this->var = $value, I of course get my exception that I'm not allowed to set that variable. Can I get around this somehow?

  • JavaScript: document properties

    - by deb
    Hi, is there a "document" property named ssh? It's a simple question. I've seen this in some code at work, but no one in the office wrote the code, so I'm stucked. The line was document.ssh.firstPing(...) firstPing was a method in the code, that is writen in js+php. But I've searched with eclipse throughout all the code and there is no ssh anywhere.
