Yeah I have a column named HybridInfo that shows up in Visual Studio under the MMJDBDataSet.xsd file and In Sql Server Management Studio.
The HybridInfo Column is under the StrainInfo Table.

Then you should probably debug your code to find out why your query is not returning the results you expect.
|
|
|
|
|
I have been debugging the code and eve inserted a break point. I even went as far as remaking the entire Database and resetting the Primary Keys.
|
|

|
|
Well I sure don't know what to tell you. The error message is very clear and specific. Either your query is bad or you are feeding your query bad information.
|
|
|
|
|
The message is telling you what is wrong; you need to check your binding to see why this column does not exist in the row.

Hello,
I have UTM coordinates ( North and East) that I would like to transform into pixels for plotting on a form. Can someone advise me how to do this with the transformation feature in C#.
Thanks,

I'm currently stuck in a exercise I'm doing and I fear I may be over thinking this, I'm trying to set up the code for a Line class and have two other Line classes each with their own thickness but can't think of anyother way besides g.DrawLine(Pens.Black, 50, 40, 126, 211); and because from how I have my code set up from class with having the DefaultLineThickness it won't cut it.
I've researched but found nothing but simple examples such as the one given and played around different methods. If anyone could help me out it'd be much appreciative. This is my current stand point.

I don't see a definition for LineOne anywhere in the above. Why not edit your question, remove most of the code and just show us the LineOne class and the implementations you want?

Is there an add on or functionality to insert a partial snippet. I an forever getting half way through a delegate and wanting to insert the tail from a snippet.
dsDashboard.DashboardSelect(VML.PeriodVMStatic.CurrentPeriod.PeriodID, (sErrorMsg, lResult) =>
{
ShowError(sErrorMsg);
xxxList = lResult;
});
I would like to get to the comma in the above statement and there insert the bold tail.

If you are using Visual Studio or Visual C# Express, you can create and save code snippets, and later, insert them into your code.

Code snippets can only be invoked from an empty line (I have about 20 standard ones set up) I am after the ability to invoke it in a partial 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.
