• MVC Display Template for Generic Type

  - by Kyle

  I am trying to use the model ListModel as a generic list model. I would like to enter on the page @Html.DisplayForModel() However the MVC is not correctly finding the templated file "ListModel.cshtml". It must work differently for generic models. What should I name the templated file in order for it to correctly be located? public class ListModel<T> { public IEnumerable<T> Models {get;set;} public string NextPage {get;set;} } I would expect it to look for "Shared/DisplayTemplates/ListModel.ascx" but it doesn't. Does anyone know?

• Testing variable types in Python

  Hello, I'm creating an initialising function for the class 'Room', and found that the program wouldn't accept the tests I was doing on the input variables.

• Syntax proposition: readability of templated type declarations

  - by Knowing me knowing you

  I wonder if syntax as follows would be helpful in your opinion as a code readability improvent and self-commenting of code: std::map<std::string name, std::vector<int> scores> myMap; In this example it clearly says and no other comment is needed, what for we are using myMap variable. Looking forward to your opinions.

• SubSonic Change DropDown Value for Load Drops SUB

  - by GTJR

  I used the subsonic generator to create some aspx pages, It works fine. On some of the pages it automaticaly generated the dropdown boxes for foreign key values. How Can change that value in the load drops code? Or where I need to change it. For instance I have a workers table and a workersweek table. The workers table has a workerid,firstname and lastname field and the workersweek has a workerID field. The generator automatically set it up to show the firstname in the dropdown. I want to change the value to be both firstname and lastname. I am sure I will have to add code that does something like firstname + " " + Lastname. I am just not sure where to do it withing the code that was generated. I see the load drops sub, but it does not seem like that is the one I need to modify.

• Change find() type of contained model or array transformation

  - by Ramon Marco Navarro

  I have the following model associations: Response->Survey Response->Question Response->Choice Survey->Question Question->Choice I want to create a form where I could answer all the questions for one survey. So I used the following to return the needed data: $questions = $this->Response->Question->find('all', array( 'conditions' => array('survey_id' => $id), 'contain' => array('Choice') ) ); Sample output for debug($questions). Questions Is there a contain() option so that an associated model returns in the find('list') format so that I could use: foreach($question as $questions) { $this-Form-select('field_name', $question['Choice']); } If no option is available, how could I do this using PHP's builting array methods? PS: The foreach block won't turn into a code block. If someone could edit and fix it, please do so and delete this line. Thank you.

• C++ Access variable value using string representing variable's name

  - by Paul Ridgway

  Hello everyone, If the title was not clear, I will try to clarify what I am asking: Imagine I have a variable called counter, I know I can see its current value by doing something like: std::cout << counter << std::endl; However, assume I have lots of variables and I don't know which I'm going to want to look at until runtime. Does anyone know a way I can fetch the value of a variable by using its name, for example: std::cout << valueOf("counter") << std::endl; I feel being able to do this might make debugging large complex projects easier. Thanks in advance for your time. PS: Please do not respond with 'Google it', I have, though maybe not with the best query to get the answer I'm looking for...

How can i make sure that the value doesn't change once i establish it?

  - by fredrick-ughimi

  Hello, I am connecting to ADS through ODBC DSN. Everything works well until I tried out my Save Routine. Data is saved quite alright but I get an error that says - "Option value changed". What could this be? Can't find in the help file. The full error message is: ODBC - 2169 [iAnywhere Solutions][Advantage ODBC Driver] Option Value Changed. I sent an email in respect of this to [email protected] since this error number falls between error numbers: 2168 - 2188 Internal Error that should be reported. I posted this question on the Newsgroup without a possitive response. Best regards, Fredrick Ughimi [email protected]
