Because i want to make a code using C# but i didn't know how to totally disable the usb port.

Your question still has nothing to do with C#. You might want to paint them red, but that doesn't mean your question would have any place in a painting forum.

|
|
|
|
And what does this have to do with C#?
And why the heck would you want to?

You can completely disable it by applying superglue.

Hi!
I am creating ErrorProvider objects with new in my code (and calling SetError(...)) while validating a form. It is also added to a List<errorprovider> Later on I call Clear() and remove the reference in the List. Will the object be garbage collected after that or am I piling up a lot of never-used ErrorProvider objects?
ErrorProvider errProvider;
List<ErrorProvider> errProviderLst = new List<ErrorProvider>();
...
errProvider = new ErrorProvider();
errProviderLst.Add(errProvider);
errProvider.SetError(c, "Ange ett heltal");
...
errProviderLst[i].Clear();
errProviderLst.RemoveAt[i];

If there are no other references to the object, then yes, when it loses scope. Implement IDisposible and have it write something to the debug output-window to verify

Hi,
I want to know that what is get and set Property in C#,
and what is difference between them???And if i want to use only get Property then how can i do this in code???
Can any one help???
What is the use of get and set property,and why we have to use get and set property and which condition???

Property get lets you retrieve the value of the property by calling a method to evaluate the property's current value, with syntactic sugar to make it look like a variable.
Property set does the same thing, but it allows you to set the value.
For example, your class may store the user information as "first name" and "second name" internally, and provide a Property FullName:
private string firstName = "";
private string lastName = "";
public string FullName
{
get { return string.Format("{0} {1}", firstName, lastName); }
set
{
string[] parts = value.Split(' ');
if (parts.Length != 2) throw new ArgumentException("Full name requires a first and last name: " + value);
firstName = parts[0];
lastName = parts[1];
}
}To provide a getter only is easy - there are two ways:
public string MyProperty { get { return "Hello"; }}
Requires no setter.
Or you could have a private setter:
private string _MyProperty = "Hello";
public string MyProperty
{
get { return _MyProperty; }
private set { _MyProperty = value; }
}This allows your class to set the value, but the outside world can only see the getter.

a small example on top of the previous answers.
Think of a car, it has properties like color, max speed, current speed, number of wheels, ...
A car can also do stuff like accelerate, turn, ...
If you would put this in the code, the properties would be put in variables and exposed via properties (get/set). Accelerate and turn are actions that are translated into methods.
Some properties can only be set when instantiating the class, eg number of wheels and maxspeed. Some can be changed from outside: You can repaint the car eg. Some can never be changed (number of wheels) and some can only be changed by using a method. (Accelerate will change the current speed and a check will prevent it from becoming higher than the max speed property).
The inner workings of properties and methods are never exposed. eg. the check where the current speed is never higher than the max speed could reside in the accelerate method or in the current speed property itself.
Read up on "encapsulation" for more info.
Hope this helps.

At the risk (to my immortal soul) of appearing to re-write code by my esteemed mentor and colleague, OriginalGriff, I'd like to add that there is almost a "standard practice" in the use of Properties in .NET, for example:
public class Employee
{
public Employee()
{
}
public void SetEmployeeName(int authorizationcode, string fname, string lname)
{
if(AuthorizeOkay(authorizationcode)
{
FirstName = fname;
FamilyName = lname;
}
else
{
NotifyUnauthorizedAccess(authorizationcode);
}
}
private string _firstName;
public string FirstName
{
private set { _firstName = value; }
get { return _firstName; }
}
private string _familyName;
public string FamilyName
{
private set { _familyName = value; }
get { return _familyName; }
}
public string FullName
{
get { return string.Format("{0}, {1}", FirstName, FamilyName); }
}
}Notes:
1. the variables declared 'private which begin with an underscore character "_" are called "backing fields."
2. the fact that all the 'get methods in the properties are public allows access by all.
3. the use of private 'set methods insure that the data can be changed only using the publicly exposed 'SetEmployeeName method.
4. the code shows a simulation in pseudo-code of the use of an "authorization code" to illustrate the idea that some vital information may be protected from "unauthorized" access. I'm not saying you "should" do anything like that, just suggesting the possibility.
You might be asking why there are separate properties for first-name and family-name; consider you have a million records and you want to search for duplicate employee last names: possibly, easier to do with only one "field" to search in each record.
Sure, there are lots more "bells and whistles" you could add here: for example, testing in the 'SetEmployeeName method for null values in either first, or family, name input strings.
There are tools, like ReSharper, that will let you click on an auto-property name and will create the private backing field and modified set/get methods for you.

Lets consider table 1 contain 30 column and table 2 is 30 column.i want to compare values one by one with respect to column name.eg.Table 1 column are A,B,C.. and Table 2 Column A,B,C....And values are xyz,abc,pqr and from table 2 xyz,jkl,pqr.Final result is Right,wrong,right likewise..

Very interesting, do you have a question?
|
|
|
|
|
Assuming the tables have the same primary key then do an inner join on the PK and compare each field.
Your question is ambiguous, do you want to compare each field in each record, the distinct of each column. try explaining it again in more detail and we may be more useful.

I assume you are talking about C# client side comparing with DataTable object(s).
It that is the case you should check this: www.dotnetperls.com/datatable-compare-rows

I didn't undersrand this code, is it for both moving polygons, (I said both)
bool AxisSeparatePolygons ( Vector N, Polygon A, Polygon B, Vector Offset, Vector Vel, float &t, float tmax)
{
float min0, max0;
float min1, max1;
CalculateInterval(N, A, min0, max0);
CalculateInterval(N, B, min1, max1);
float h = Offset dot N;
min0 += h;
max0 += h;
float d0 = min0 - max1; // if overlapped, do < 0
float d1 = min1 - max0; // if overlapped, d1 > 0
// separated, test dynamic intervals
if (d0 > 0.0f || d1 > 0.0f)
{
float v = Vel dot N;
// small velocity, so only the overlap test will be relevant.
if (fabs(v) < 0.0000001f)
return false;
float t0 =-d0 / v; // time of impact to d0 reaches 0
float t1 = d1 / v; // time of impact to d0 reaches 1
// sort the times.
if (t0 > t1)
{
float temp = t0;
t0 = t1;
t1 = temp;
}
// take the minimum positive
taxis = (t0 > 0.0f)? t0 : t1;
// intersection time too late or back in time, no collision
if (taxis < 0.0f || taxis > tmax)
return true;
return false;
}
else
{
// overlap. get the interval, as a the smallest of |d0| and |d1|
// return negative number to mark it as an overlap
taxis = (d0 > d1)? d0 : d1;
return false;
}
}
it will only calculate time of velocity to overlap one of them to the other not both, but my exe make the right moment of collision, how that happens in sat? calculate next frame for both and use thales equation, because that's what I do.

Is this C++ code?
(The float &t is clearly NOT C#)
This is in the wrong forum.
It should be in: C / C++ / MFC[^]

anyway I can answer my post, it was the relative velocity, that make the right moment yep

Hi All,
Greetings!!.
I have got a requirement where in i need to write a C# code which should do the following tasks.
1) Pushing the files from ETL landing zone to Share point site(2013 version).
2) Once the files have been copied a mail has to be send to group of people with that share point URL.
This is a bit urgent.
Hence immediate response along with the step by step source code would be highly appreciated.
Thanks in advance.
Regards,
Nanda Kishore.

You are paying as much as the others and are equally important as everybody else; it is not urgent to me.
Having an alert mailed of a library changes should be simply a matter of configuration. Since I don't know what ETL is (and I'm too lazy to Google) I can't say how to get that into a library. Still, you could simply take the webservice (sharepoint has those), upload it and mail some list yourself.

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 Freelancer.com and ask there.
But be aware: you get what you pay for. Pay peanuts, get monkeys.
And BTW: It may be urgent to you, but it isn't to us. All that your stressing the urgency does is to make us think you have left it too late, and want us to do it for you. This annoys some people, and can slow a response.

Use C# and the SharePoint client side object model (CSOM).
If you get it right the first time, it should take about a month to build.

Using the samples, yes. A new or existing data model? Maybe. No SharePoint experience? Good luck.
