Hello
I created more than 20 games on windows phone7 .I want to convert that all games for windows 8 ultrabook but touches are not working properly in ultrabook that means gesture..anyone know how to handle or enable gesture in windows 8 ultrabook
my code is for touches:
In constuctor()
{
EnabledGestures = GestureType.Tap;
}
public override void HandleInput(InputState input)
{
foreach (GestureSample gesture in input.Gestures)
{
if (gesture.GestureType == GestureType.Tap)
{
}
}
}
whenever i am touching windows 8 ultrabook.Its always showing gesture count is 0.
and its not coming inside.
foreach (GestureSample gesture in input.Gestures)
{
}
so how we enable gesture in windows 8 ultrabook.
whenever i am touching windows 8 ultrabook.gesture count comes 0.
its not coming inside.
foreach (GestureSample gesture in input.Gestures)
{
}
so how we enable gesture in windows 8 ultrabook.
please reply me ASAP.
waiting for ur reply
Thank U
Best Regards,
Ashish Gupta

See this MSDN page[^].
One of these days I'm going to think of a really clever signature.

Perhaps keep your eye on what this company, LeapMotion, is developing: high-precision gestural control without touching the screen:[^].

Hi,
I need to improve oops advancd concepts and learn advanced in c# dot net.
any one can help to me .

A good place to start with taking your OO ability to the next level is to understand something called SOLID. Now, a guy called Bob Martin popularised these principles, and you can find details here[^].
In a nutshell, it's how to approach writing complex systems using easy to understand principles. Now, although these principles are easy to understand, it doesn't stand to reason that they are easy to apply. Applying SOLID is hard - primarily because there's always a temptation to cut corners.
Please note that these aren't the only principles you can use - Bob goes on to list other principles that can be applied in the article, but these are a good place to start.
Can I suggest that you change your user name? If you want to be spammed, your user name here is a good way to go about it.

After you've learned the basics of OOP, read Design Patterns (Gamma et al) for the advanced concepts.
Design patterns are how you use OOP to solve problems.

Hi all,
I want list out all the open ports for a particular IP Address in c# windows application.
How can i do it ?
Thanks in advance.

Have a look at this tip Find an open port on a machine using C#[^].

The problem with that approach is that it only works for the local machine. I believe the OP is looking to scan ports on remote machines.

Ahh! Reading the question right is generally a good start

What you are trying to achieve here is a port scanner. This[^] article should give you a decent head start - but there are a couple of things to be aware of.
1. If you are scanning all ports, you should consider running the checks via multiple threads. The reason for this is because checking a port is a time consuming process.
2. Just because the list identifies that a port is free, it doesn't mean that the port will be free when you come to request it. Another application could have taken that port before you get to it, so don't consider that the list is definitive.

If you are attempting to create a port scanner then I STRONGLY suggest that you consider the following....
Do not do this unless YOU own the network or you have PERMISSION from the owner of the network in WRITING to do this.
People have been expelled from school, lost their network connectivity, been fired from jobs, have had civil judgments rendered against them and even criminally prosecuted because they did this. Even when they thought they had a legitimate need for the functionality.

Current working code in a public static class: a List<Type> used internally:
using System;
using System.Windows.Forms;
using System.Collections.Generic;
private static List<Type> OkToModify = new List<Type>
{
typeof(CheckBox),
typeof(TextBox),
typeof(Button),
typeof(Panel),
typeof(Label)
};By "working:" I mean that I can use the List<Type> to test if a given Control passed into the public static class is okay for the uses I make of it. Through, simply:
if (OkToModify.Contains(cntrl.GetType())) { processControl(cntrl) };I keep thinking that somewhere in my reading (Skeet ? StackOverFlow ?), or here on CP, I have seen a "niftier" way to do this.
Appreciate any alternatives.
thanks, Bill

HashSet 
But as you may have read in one of my articles (you've them all by now, right?) that may not handle derived types and Interfaces as well as you might like.

Mercy, please: give me half-a-day to study them, here at UTC + 7, where my computer "day" begins at 5am (six hours ago), and is interrupted, about now, with business errands followed by, at high-temperature time in the afternoon, a shower and long siesta ...
Of course, "studying your articles," does not imply I will understand them !
But, learn from them: that I guarantee

PBC, I read the "EnumTree" and "TypeTransMogrifier" articles: neither mentioned the use of a Hashset, although perhaps you use one somewhere in the code I didn't bother examining.
I do plan to study the "Enum Utilities" article, which was quite popularly rated compared to the first two articles.
Both articles I read seemed to me be over-engineered to the point of being "esoteric," and I could not imagine one real-world use-case where such techniques as you demonstrate are really required.
That analysis may simply be saying something about me, and my level of coding knowledge, and problems I deal with, rather than saying anything about you. For all I know, such complex solutions as you present in those two articles: are ideal in certain real-world situations.
Of course, I respect your achievements, five out of seven "platinums," on Code Project is very impressive !
best, Bill
p.s. the "using directives:"
using System;
using System.Windows.Forms;
using System.Collections.Generic;
are absolutely required, or the code I showed you will not build. Remember this is a stand-alone static-class, not a "partial Form."

Perhaps not, but if all you want to do is check for the existence of an item in a set, HashSet is "better" and a List.

BillWoodruff wrote: problems I deal with
Most likely. In many cases they're not worth the overhead. Basically it depends on the duration of the application and the number of times the structure is accessed. Many apps (Web apps?) run for only a very short period and access such a structure once then stop. But I work on a lot of Windows Services that run 24/7 for months or years and can access the structure a great many times in rapid succession, so I feel it's worthwhile.
BillWoodruff wrote: the code I showed you will not build as written
FTFY. Everything can be fully-specified -- using directives are a matter of convenience.

This code is fine. You are overthinking it. If the 5 controls were somehow related, then I might give a different answer, but seeing as they are completely unrelated, this solution is perfectly fine.

You may find them convenient, but they are not required... unless some coding standard forced upon you says so.

Response to edit:
I think what he meant is the using directives are not required as everything can be written in full i.e.
private static System.Collections.Generic.List<System.Type> OkToModify =
new System.Collections.Generic.List<System.Type>
{
typeof(System.Windows.Forms.CheckBox),
typeof(System.Windows.Forms.TextBox),
typeof(System.Windows.Forms.Button),
typeof(System.Windows.Forms.Panel),
typeof(System.Windows.Forms.Label)
};
Personally, I think this is horrible and I always use usings wherever possible, but some will disagree...

Bill, the code you have there looks to be about as optimised as you are going to get. The only thing I would wonder about, though, is the extensibility of your model here. Basically, what you have here could end up violating the Open-Closed principal which states that a class should be open to extension but closed to modification.
So, what does that fancy term mean? Well, it simply means that if you decide to add another type in future, you have to crack open your code and modify it. It's up to you to decide whether or not this is acceptable to you. There are various ways to solve this problem, but one way could simply be to store the types in your configuration (comma delimited would do), and then parse them on the way in. So, suppose you store them in a key in app.config (for example), what would the code look like? Well, this should help:
private void PopulateOkToModifyCollection()
{
string types = ConfigurationManager.AppSettings["ModifiableTypes"];
if (string.IsNullOrWhitespace(types))
return;
string[] allowedTypes = types.Split(',');
foreach (string allowed in allowedTypes)
{
Type type = Type.GetType(allowed);
if (type == null)
{
throw new ArgumentException(string.Format("The type {0} is not a valid type", allowed));
}
OkToModify.Add(type);
}
}Note that when you add the type to your comma separated list in the AppSettings key, it should be the fully qualified type.
