What?
One of these days I'm going to think of a really clever signature.
|
|
|
|

Actually, VERY applicable. There a lots of examples out on the web. You don't need someone here to hold your hand through this and spoon feed you.

I not found any examples since 8am
|
|
|
|
|
So you're after someone else to do your work for you. Is that what you're saying?
|
|
|
|

Well I have no idea what you have been searching for, but Google found quite a selection[^].

Method AddRange takes IEnumerable collection it makes perfect sense since we want to add second collection to our first list.
http://msdn.microsoft.com/en-us/library/z883w3dc%28v=vs.80%29.aspx[^]
But when you want to remove some items from collection that are in second collection (scenarion 2 grids with items and one bucket of possibilities for them, and cannot have shared items, available grid and items selected by user grid), there is RemoveRange method, right? No this method takes 2 ints
http://msdn.microsoft.com/en-US/library/y33yd2b5%28v=vs.80%29.aspx[^]. Odd.
RemoveAll? This for instance takes predicate for items. http://msdn.microsoft.com/en-US/library/wdka673a%28v=vs.80%29.aspx[^]So why this is called RemoveAll? Since it's takes predicate as Where takes why this is not called RemoveWhere? From RemoveAll I would expect behavior like Clear method, but we don't need another one like that.
Method Remove takes item and removes it from collection. So why there is not method that takes range? How many times you have to remove items by range of indexes from collection (RemoveRange)? It would have to be ordered list to make it usable at some point since when you get index and number of items to remove you have to order and iterate it and since you do that why not just remove those items already? So in the end I using AddRange and extension method RemoveRange that iterates and calls Remove on second collection. Am I allone on that?
No more Mister Nice Guy... >: |

Yes/no. With a large framework, there's bound to be some inconsistencies.
Yes, it would help if we could deduce the name of the method we want to call, based on fixed patterns. No, I don't see it happening.
As for the range, I'd expect two ints, as the indexes are a good way to define a range. That's a bit harder to do with an IEnumerable.
RemoveWhere(thisconditionistrue) or RemoveAll(thisconditionistrue); yes, your version sounds better, but it'll be hard to convince MS to change it. Especially after it's being used already in a lot of sourcecode.

provide the details to get current location through gps in desktop apps
|
|
|
|
|
Well, first of all you'll need hardware capable of receiving GPS data. Then you'll need to write some code to get this data. Finally, you need to learn how to say please; my first temptation was just to write "no". I don't work for you and you aren't a client, so I don't take well to orders from you.

Hello, when we move the scroll bar of a program we get this exception. I think its some thing to do with Index was out of range? Is this the correct section to post in? I'm using Windows 7 64 bit if that helps. Thank you.

comboLineType.SelectedIndex: is that -1? And how does GetLineType() look like - is the ArrayList you use there correctly initialized?

this.Mentor(this.comboLineType.SelectedIndex, Convert.ToDouble(this.utilSlackParamBar.Value) / 100.0 * this.network.GetLineType(this.comboLineType.SelectedIndex).Linespeed, 1.0, 0.4, 0.2, Convert.ToDouble(this.alphaParamBar.Value) / 100.0, "F", 1.0 - Convert.ToDouble(this.utilSlackParamBar.Value) / 100.0);
Writing composite expressions such as this in a single line of code is just asking for trouble. You have no way of checking any of the interim values that are being selected or calculated.

What extra information is that supposed to convey?

You should have posted that earlier. Why it's obvious now. I can obviously tell what your code looks like from the different shades of grey there (I counted 50 of them).
And, yes, that was sarcasm.

The program is available on the internet. Just search for 'wlvnet' on Google, please.

If you expect people to help you then try responding to some of the questions that have been posted. If you think people are going to download some vaguely identified piece of code from the internet, build it and debug it on your behalf, then I'm afraid you are going to be disappointed.

What is Interface? In Which Scenarios Use It?

Both of these questions could be answered by a quick Google search[^], or reading the documentation.

I suggest you look up what it is, and try to formulate an answer to your homework. I can give you the answers without thinking, but that would be just as useful as counting the grains of sand in a desert - it'd be a waste of time.

Abstract Class ? In which Scenarios use it over Interface?
Raghu RR
|
|
|
|
|
An interface defines the signatures for a set of members that implementers must provide. Interfaces cannot provide implementation details for the members. For example, the ICollection interface defines members related to working with collections. Every class that implements the interface must supply the implementation details for these members. Classes can implement multiple interfaces.
Classes define both member signatures and implementation details for each member. Abstract classes can behave like interfaces or regular classes in that they can define members, and they can provide implementation details but are not required to do so. If an abstract class does not provide implementation details, concrete classes that inherit from the abstract class are required to provide the implementation.
So here you can see the difference. Based on the understanding about your requirements in the project. You should implement either Interface of abstract class.

Hello - My company has a large TFS structure and my team has a requirement to replace references to one site domain with references to another site domain.
I was trying to see if there was a way to do this search through TFS itself. In VS, Edit > Find and Replace > Find in Files only searches the sln open in VS which does not satisfy my requirement. File > Source Control > Find in Source Control > Wildcard opens a Search window with Recursive checked by default. However, this search only appears to search file and folder names but not file contents. For example, a search for "string" at the TFS root level should return hundreds of references but only returns a reference to a folder named "string".
So is there a way to do a full recursive search for text within the files from the root level of TFS? The ways I described above don't seem to accomplish my goal unless I'm missing something. I'm guessing someone here has had a requirement to something similar to this before....
