Mycroft Holmes wrote: Code snippets can only be invoked from an empty line
Um.
Not for me...I have a standard snippet to insert a new event: A Simple Code Snippet to Add an Event[^] which works from "evh" [TAB][TAB]. And if I do this:
string hello = evh
And press Tab twice, I get this:
string hello = /// <summary>
/// Event to indicate Description
/// </summary>
public event EventHandler Name;
/// <summary>
/// Called to signal to subscribers that Description
/// </summary>
/// <param name="e"></param>
protected virtual void OnName(EventArgs e)
{
EventHandler eh = Name;
if (eh != null)
{
eh(this, e);
}
}and the cursor is ready to enter the Description.
So can't you do something like this?

You will see a conceptual framework that I came up with, to the best of my understanding, as I have never worked with the project.
NONMEM (http://www.iconplc.c...roducts/nonmem/) is a software that analysis data that helps provide predictions on a population level, instead of on a single patient. A statistician is responsible to analyse these given data and provide models (sorry, not modules), which are sophisticated mathematical equations, that help predict level of drug concentrations in the blood. Ultimately, we take this data and predict the appropriate doses (output).
So, the statistician will provide the csv file with the required data to be applied to the model. On what bases the model to be chosen, this yet to be figured out. However, I can speculate that the model to be applied to according to its respective product/drug. For example, patient need drug A, so model C corresponds to that drug. Therefore, I want the csv file to be applied to model C because that patient will use drug A.
Does that make sense?

In a rather vague way, yes. But more importantly, what does it have to do with C#?

So I was discussing this subject with one of my coworkers after he asked me to review some of his code. Our software breaks apart data files, and feeds them to a separate service to be stored in a SQL Server database. His "Record" class has several properties for each of the fields in the client's data file. This particular client's module uses the FileHelpers utility library to read a CSV format, so we're not parsing it manually. Three of the fields are: City, State, ZIP.
Ultimately, we only really care to access the City/State/ZIP as a whole, a formatted string (e.g. Small-Town, USA 12345). With that being said, does it make more sense to loop over a collection of records and call a method like so:
private void SetCityStateZip(Record myRecord)
{
myRecord.CityStateZip = string.Format("{0}, {1} {2}", myRecord.City, myRecord.State, myRecord.Zip);
}
"CityStateZip" is a property in the Record class, referencing a field "_cityStateZip".
Or does it make more sense, instead of creating a whole new field/property, to use a property with a getter that contains the logic as follows:
public string CityStateZip
{
get
{
return string.Format("{0}, {1} {2}", _city, _state, _zip);
}
}
I ask because to me, it makes sense to use the getter with simple logic, as opposed to a separate method. Why? Because CityStateZip is only accessed once for each record when the processing service takes place. The individual City/State/ZIP properties are not used elsewhere.
I figured, for the sake of example, if a data file has 10,000 records, and you call the "SetCityStateZip" method for each, you're setting 10,000 "CityStateZip" properties well before it's even used. There are actually TWO properties like this, so that's 20,000 fields/properties being set when they're each only referenced once in processing. Why assign extra "string" values?
Hope this makes sense. Kind of typed it in a hurry. Just wanting some feedback, as a coworker stated that he believes it's a bad idea to use logic in getters. If he is correct, so be it. But I sometimes enjoy a second/third/fourth/nth. opinion.

Personally, I'd probably go for the property, but...there is a third option which I'd probably prefer: override ToString to return the string version:
public override string ToString()
{
return string.Format("{0}, {1} {2}", _city, _state, _zip);
}
That way, controls such as DataGridView , ComboBox and so forth can also use it.

Which object overrides the ToString() method? I understand the purpose, but the Record class holds far more than just the fields I listed.

In that case, just stick with the property - it should be more performant since it won't be creating unnecessary strings, and the string will be up-to-date with any changes to the underlying data.

IMHO, the 2nd option makes much more sense - a get only property that returns the composite information. If the individual components (city, state and zip) are not read by consumers of Record, they should only be private fields and not exposed as properties.
/ravi

|
|
|

Are they any proven advantages, so to speak, in using that over the first option? I mean, in terms of maintainability, readability, etc.?

Yes, in terms of program verification and maintenance. The first method imposes a requirement that SetCityStateZip() be invoked prior to using the composite value. The latter imposes no such requirement, and further guarantees that the composite will always be correct if its constituent parts are correct.
Going further, I suggest Record have a constructor that consumes a CSV string (or better yet a bag of properties), instead of requiring one or more Set... methods or private property setters to be invoked. This dependency injection ensures a Record instance can never exist in an invalid state (i.e. constructed but not having all its properties set) before it's used. This also allows a Record to be easily unit tested by mocking a set of parsed property values.

i need the marching cubes algorithmes in c#
thanks

If you want the algorithm, then google would have found it for you very quickly: it took me around 3 seconds: http://en.wikipedia.org/wiki/Marching_cubes[^]
So in future, please try to do at least basic research yourself, and not waste your time or ours.
If you want us to code it for you, that's different.
Please pick one of the two following options:
1) We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.
Try it yourself, you may find it is not as difficult as you think!
Or
2) It doesn't quite work like that.
We do not do your work for you.
If you want someone to write your code, you have to pay - I suggest you go to VWorker.com and ask there.
But be aware: you get what you pay for. Pay peanuts, get monkeys.
Your choice!

Hi. I'm trying to make a project. it's suppose to capture the firdt frame and save it as background. then compare it with current frame using background substraction, then detect human using HOG. if human detected, the the frame will recorded.
but when I run the program, it only display current frame in GUI. the background also didn't saved, so the rest process cannot proceed.
