  • Creating a new Guid inside a code snippet using c#

    - by Rob
    I want to make an intellisense code snippet using Ctl K + Ctl X that actually executes code when it runs... for example, I would like to do the following: <![CDATA[string.Format("{MM/dd/yyyy}", System.DateTime.Now);]]> But rather than giving me that string value, I want the date in the format specified. Another example of what I want is to create a new Guid but truncate to the first octet, so I would want to use a create a new Guid using System.Guid.NewGuid(); to give me {798400D6-7CEC-41f9-B6AA-116B926802FE} for example but I want the value: 798400D6 from the code snippet. I'm open to not using an Intellisense Code Snippet.. I just thought that would be easy.

  • variable being weirdly deleted

    - by calccrypto
    im having a weird problem with one variable: its not being recognized but its still printing. i would post my code, but it is massive. the basic idea is: # pseudocode def function(stuff): <do stuff> # These are the only 2 conditions if tag == 3: pka = <a string> if tag == 4: pka = <a string> print pka # (1) print pka # (2) <do stuff not modifying pka> print pka # (3) if pka == 'RSA': <do stuff> elif pka == 'DSA': <do stuff> my code will error at (2). however, it will print out (1), (2), and (3), all of which are the same. is there any general explanation of why this is happening? if my code is really needed, i will post it, but otherwise, i would rather not due to its size update: now the code will error at the if statement after (3), saying UnboundLocalError: local variable 'pka' referenced before assignment even though (1),(2),(3) just printed

  • How to look up an NHibernate entity's table mapping from the type of the entity?

    - by snicker
    Once I've mapped my domain in NHibernate, how can I reverse lookup those mappings somewhere else in my code? Example: The entity Pony is mapped to a table named "AAZF1203" for some reason. (Stupid legacy database table names!) I want to find out that table name from the NH mappings using only the typeof(Pony) because I have to write a query elsewhere. How can I make the following test pass? private const string LegacyPonyTableName = "AAZF1203"; [Test] public void MakeSureThatThePonyEntityIsMappedToCorrectTable() { string ponyTable = GetNHibernateTableMappingFor(typeof(Pony)); Assert.AreEqual(LegacyPonyTableName, ponyTable); } In other words, what does the GetNHibernateTableMappingFor(Type t) need to look like?

  • Dreamweaver recordset filter - Display all records as default

    - by Drew
    I am trying to create a simple search form to filter the results in the dynamic table. The search form is on the same pages as the results and posts to itself. I get the search string from the post variable. It is working, but I can't figure out how to set the default value to display all results. Dreamweaver automatically sets the default value to -1, and therefore no results are displayed on the initial load. How do I change this to display ALL records as default and the filter only if there is search string defined.

  • Does Postgresql varchar count using unicode character length or ASCII character length?

    - by bennylope
    I tried importing a database dump from a SQL file and the insert failed when inserting the string Mér into a field defined as varying(3). I didn't capture the exact error, but it pointed to that specific value with the constraint of varying(3). Given that I considered this unimportant to what I was doing at the time, I just changed the value to Mer, it worked, and I moved on. Is a varying field with its limit taking into account length of the byte string? What really boggles my mind is that this was dumped from another PostgreSQL database. So it doesn't make sense how a constraint could allow the value to be written initially.

  • Can fields of the class and arguments of the method interfere?

    - by Roman
    I have a class with a fields called "a". In the class I have a method and in the list of arguments of this method I also have "a". So, which "a" I will see inside of the method? Will it be the field or it will be the argument of the method? public class myClass { private String a; // Method which sets the value of the field "a". public void setA(String a) { a = a; } } By the way, there is a similar situation. A method has some local (for method) variables whose names coincide with the names of the fields. What will the "see" the method if I refer to such a method-local variable inside the method (the field or the local variable)?

  • Unique constraint on more than 10 columns

    - by tk
    I have a time-series simulation model which has more than 10 input variables. The number of distinct simulation instances would be more than 1 million, and each simulation instance generates a few output rows every day. To save the simulation result in a relational database, i designed tables like this. Table SimulationModel { simul_id : integer (primary key), input0 : string or numeric, input1 : string or numeric, ...} Table SimulationOutput { dt : DateTime (primary key), simul_id : integer (primary key), output0 : numeric, ...} My question is, is it fine to put an unique constraint on all of the input columns of SimulationModel table? If it is not a good idea, then what kind of other options do i have to make sure each model is unique?

  • Modify bash variables with sed

    - by Alexander Cska
    I am trying to modify a number of environmental variables containing predefined compiler flags. To do so, I tried using a bash loop that goes over all environmental variables listed with "env". for i in $(env | grep ipo | awk 'BEGIN {FS="="} ; { print $1 } ' ) do echo $(sed -e "s/-ipo/ / ; s/-axAVX/ /" <<< $i) done This is not working since the loop variable $i contains just the name of the environmental variable stored as a character string. I tried searching a method to convert a string into a variable but things started becoming unnecessary complicated. The basic problem is how to properly supply the environmental variable itself to sed. Any ideas how to properly modify my script are welcome. Thanks, Alex

  • Variable function name Javascript.

    I'm sorting array: myArray.sort(comparators.some_comparator); and I have several comparator to choose from: comparators = { asc_firstname_comparator : function(o1, o2){ ... } desc_firstname_comparator : function(o1, o2){ ... } etc... } I want to write function which returns certain comparator depending on input data. It should figure out comparator from string inputs, something like this: function chooseComparator(field, order){ return "comparators."+order+"_"+field+"_comparator"; } So is it possible to pass only function name string to sort() method or I'll need to pass reference to correct comparator somehow?

  • How to get MVC action to return 404

    - by zaph0d
    I have an action that takes in a string that is used to retrieve some data. If this string results in no data being returned (maybe because it has been deleted), I want to return a 404 and display an error page. I currently just use return a special view that display a friendly error message specific to this action saying that the item was not found. This works fine, but would ideally like to return a 404 status code so search engines know that this content no longer exists and can remove it from the search results. What is the best way to go about this? Is it as simple as setting Response.StatusCode = 404?
