I'm trying to find all enabled resharper Commands via the menus. I can find all the menu items using the following code. However I cannot find how to get the actual command from the DTE commands collection.
var resharper = ((CommandBars)_dte.Application.CommandBars)["RESHARPER"];
var refactor = (CommandBarPopup)resharper.Controls["&Refactor"].Control;
foreach (var c in refactor.Controls)
{
var cbb = c as CommandBarButtonClass;
if (cbb != null)
{
yield return new VoiceCommand
{
Command = _dte.Commands.Item(???),
Key = cbb.accName,
};
}
}
What property should I use to look up the command (??? above)?
Thank you,
Erick
You want to use the CommandInfo method, like this:
Guid guid;
int id;
_dte.Commands.CommandInfo(cbb, out guid, out id);
yield return new VoiceCommand
{
Command = _dte.Commands.Item(guid, id),
Key = cbb.accName,
};

I use a SQLite database to populate a listview with a generic list of TodoItems:
ListView.ItemsSource = await App.Database.GetItemsAsync("SELECT * FROM [TodoItem]");
I can read data of the same kind from a database source using the HttpClient class as well via
public async Task<List<TodoItem>> ReadDataAsync ()
....
Items = new List<TodoItem> ();
....
var content = await response.Content.ReadAsStringAsync ();
Items = JsonConvert.DeserializeObject <List<TodoItem>> (content);
....
return Items;
whereafter I can use this as a data source as well:
ListView.ItemsSource = await App.ReadDataAsync();
Both ways work well.
What I want now is combine both routines to accomplish a code which checks whether we have an online connection, if yes, drop the database and populate it using the result of ReadDataAsync from above, if no, leave the database alone.
I found no way to directly assign a List to my database, overwriting the whole contents, I think of something like:
App.Database.Items = await App.ReadDataAsync();
but SQLite doesn't seem to expose the data store directly. How can I accomplish this?
For android for example, you could try: There's no need to drop the database.
//Check for internet connection
var connectivityManager =
(ConnectivityManager)this.GetSystemService("connectivity");
var activeConnection = connectivityManager.ActiveNetworkInfo;
if ((activeConnection != null) && activeConnection.IsConnected)
{
//Make call to the API
var list = await App.ReadDataAsync();
//Update or Insert local records
foreach (var item in list)
{
var success = UpdateOrInsert(item);
//Do something after - like retry incase of failure
}
}
The UpdatedOrInsert method can look like:
private bool UpdateOrInsert(TodoItem item)
{
var rowsAffected = App.Database.Update(item);
if (rowsAffected == 0)
{
// The item doesn't exist in the database, therefore insert it
rowsAffected = App.Database.Insert(item);
}
var success = rowsAffected > 0;
return success;
}
We have an application that integrates with SCCM 2012 and saves custom SCCM applications to SCCM.
The problem I am having is that attempting to save one of our custom applications when the SCCM administrator has set the application to be in the retired state causes our application to fail the saving process.
I'd like to be able to query the SCCM application state in order to determine before we attempt the save operation whether the given application is Active or Retired.
I can find no reference to "retired" status in the SMS_Application Server WMI help or any of the other pages:
http://msdn.microsoft.com/en-us/library/hh949251.aspx
I have noticed that there is a Restore() method which looks like it will change the status of a Retired package back to Active, however that's not quite what I want to do.
Can anyone help me determine how to find an applications current status?
Thanks.
There's a method in the SCCM 2012 PowerShell cmdlets that appears to be retrieving the expired status. Here's the c# code (decompiled from the dll AppUI.PS.AppMan.dll on the SCCM server)
private bool IsApplicationRetired(IResultObject applicaction)
{
IResultObject[] resultObjectArray = null;
int integerValue = applicaction["CI_ID"].IntegerValue;
object[] objArray = new object[] { integerValue };
resultObjectArray = base.ExecuteQuery(string.Format(CultureInfo.InvariantCulture, "SELECT * FROM SMS_Application WHERE CI_ID = {0}", objArray));
IResultObject[] resultObjectArray1 = resultObjectArray;
int num = 0;
if (num < (int)resultObjectArray1.Length)
{
IResultObject resultObject = resultObjectArray1[num];
this.isApplicationRetired = resultObject["IsExpired"].BooleanValue;
}
if (this.isApplicationRetired)
{
object[] objArray1 = new object[] { integerValue };
IResultObject instance = base.ConnectionManager.GetInstance(string.Format(CultureInfo.InvariantCulture, "SMS_Application.CI_ID={0}", objArray1));
if (instance != null)
{
string stringValue = instance["ModelName"].StringValue;
instance.Dispose();
object[] objArray2 = new object[] { base.ConnectionManager.EscapeQueryString(stringValue, ConnectionManagerBase.EscapeQuoteType.SingleQuote) };
resultObjectArray = base.ExecuteQuery(string.Format(CultureInfo.InvariantCulture, "SELECT CI_ID FROM SMS_Application WHERE ModelName = '{0}' AND IsLatest = 1 AND IsExpired = 0", objArray2));
IResultObject[] resultObjectArray2 = resultObjectArray;
int num1 = 0;
if (num1 < (int)resultObjectArray2.Length)
{
IResultObject resultObject1 = resultObjectArray2[num1];
if (resultObject1["CI_ID"].IntegerValue != integerValue)
{
this.isApplicationRetired = false;
}
}
}
}
return this.isApplicationRetired;
}
I have an array-list that contains some UserID.
I need a query like this:
vat tmp= users.select(a=> a.UserID in (arraylist));
what can I do?
If it's actually in an ArrayList, you should create a List<T> or array first. Then you can use Contains:
// Use the appropriate type, of course.
var ids = arraylist.Cast<string>().ToList();
var tmp = users.Select(a => ids.Contains(a.UserID));
While using Contains on the plain ArrayList may well compile, I would expect it to fail at execution time, assuming users is an IQueryable<>.
List<long> list =new List<long>();
var selected = from n in users where list.Contains(n.ID) select n ;
OR
var selected = users.Where(a=> list.Contains(a.ID)).ToList();
This is the solution I used.
public static IEnumerable<SettingModel> GetSettingBySettingKeys(params string[] settingKey)
{
using (var db = new BoxCoreModelEntities())
{
foreach (var key in settingKey)
{
var key1 = key;
yield return Map(db.Settings.Where(s => s.SettingKey == key1).First());
}
}
}
I have a collection of CLR objects. The class definition for the object has three properties: FirstName, LastName, BirthDate.
I have a string that reflects the name of the property the collection should be sorted by. In addition, I have a sorting direction. How do I dynamically apply this sorting information to my collection? Please note that sorting could be multi-layer, so for instance I could sort by LastName, and then by FirstName.
Currently, I'm trying the following without any luck:
var results = myCollection.OrderBy(sortProperty);
However, I'm getting a message that says:
... does not contain a defintion for 'OrderBy' and the best extension method overload ... has some invalid arguments.
Okay, my argument with SLaks in his comments has compelled me to come up with an answer :)
I'm assuming that you only need to support LINQ to Objects. Here's some code which needs significant amounts of validation adding, but does work:
// We want the overload which doesn't take an EqualityComparer.
private static MethodInfo OrderByMethod = typeof(Enumerable)
.GetMethods(BindingFlags.Public | BindingFlags.Static)
.Where(method => method.Name == "OrderBy"
&& method.GetParameters().Length == 2)
.Single();
public static IOrderedEnumerable<TSource> OrderByProperty<TSource>(
this IEnumerable<TSource> source,
string propertyName)
{
// TODO: Lots of validation :)
PropertyInfo property = typeof(TSource).GetProperty(propertyName);
MethodInfo getter = property.GetGetMethod();
Type propType = property.PropertyType;
Type funcType = typeof(Func<,>).MakeGenericType(typeof(TSource), propType);
Delegate func = Delegate.CreateDelegate(funcType, getter);
MethodInfo constructedMethod = OrderByMethod.MakeGenericMethod(
typeof(TSource), propType);
return (IOrderedEnumerable<TSource>) constructedMethod.Invoke(null,
new object[] { source, func });
}
Test code:
string[] foo = new string[] { "Jon", "Holly", "Tom", "William", "Robin" };
foreach (string x in foo.OrderByProperty("Length"))
{
Console.WriteLine(x);
}
Output:
Jon
Tom
Holly
Robin
William
It even returns an IOrderedEnumerable<TSource> so you can chain ThenBy clauses on as normal :)
You need to build an Expression Tree and pass it to OrderBy.
It would look something like this:
var param = Expression.Parameter(typeof(MyClass));
var expression = Expression.Lambda<Func<MyClass, PropertyType>>(
Expression.Property(param, sortProperty),
param
);
Alternatively, you can use Dynamic LINQ, which will allow your code to work as-is.
protected void sort_grd(object sender, GridViewSortEventArgs e)
{
if (Convert.ToBoolean(ViewState["order"]) == true)
{
ViewState["order"] = false;
}
else
{
ViewState["order"] = true;
}
ViewState["SortExp"] = e.SortExpression;
dataBind(Convert.ToBoolean(ViewState["order"]), e.SortExpression);
}
public void dataBind(bool ord, string SortExp)
{
var db = new DataClasses1DataContext(); //linq to sql class
var Name = from Ban in db.tbl_Names.AsEnumerable()
select new
{
First_Name = Ban.Banner_Name,
Last_Name = Ban.Banner_Project
};
if (ord)
{
Name = BannerName.OrderBy(q => q.GetType().GetProperty(SortExp).GetValue(q, null));
}
else
{
Name = BannerName.OrderByDescending(q => q.GetType().GetProperty(SortExp).GetValue(q, null));
}
grdSelectColumn.DataSource = Name ;
grdSelectColumn.DataBind();
}
you can do this with Linq
var results = from c in myCollection
orderby c.SortProperty
select c;
For dynamic sorting you could evaluate the string i.e. something like
List<MyObject> foo = new List<MyObject>();
string sortProperty = "LastName";
var result = foo.OrderBy(x =>
{
if (sortProperty == "LastName")
return x.LastName;
else
return x.FirstName;
});
For a more generic solution see this SO thread: Strongly typed dynamic Linq sorting
For this sort of dynamic work I've been using the Dynamic LINQ library which makes this sort of thing easy:
http://weblogs.asp.net/scottgu/archive/2008/01/07/dynamic-linq-part-1-using-the-linq-dynamic-query-library.aspx
http://msdn2.microsoft.com/en-us/vcsharp/bb894665.aspx
You can copy paste the method I post in that answer, and change the signature/method names:
How to make the position of a LINQ Query SELECT variable
You can actually use your original line of code
var results = myCollection.OrderBy(sortProperty);
simply by using the System.Linq.Dynamic library.
If you get a compiler error (something like cannot convert from or does not contain a definition...) you may have to do it like this:
var results = myCollection.AsQueryable().OrderBy(sortProperty);
No need for any expression trees or data binding.
You will need to use reflection to get the PropertyInfo, and then use that to build an expression tree. Something like this:
var entityType = typeof(TEntity);
var prop = entityType.GetProperty(sortProperty);
var param = Expression.Parameter(entityType, "x");
var access = Expression.Lambda(Expression.MakeMemberAccess(param, prop), param);
var ordered = (IOrderedQueryable<TEntity>) Queryable.OrderBy(
myCollection,
(dynamic) access);
Does anyone know how to copy all the lines in the Visual Studio "Find Symbol Results" window onto the clipboard? You can copy a single line, but I want to copy them all.
I can't believe that I'm the first one to want to do this, but I can't even find a discussion about this apparently missing feature.
Here is some code that uses the .Net Automation library to copy all the text to the clipboard.
Start a new WinForms project and then add the following references:
WindowsBase
UIAutomationTypes
UIAutomationClient
System.Xaml
PresentationCore
PresentationFramework
System.Management
The code also explains how to setup a menu item in visual studio to copy the contents to the clipboard.
Edit: The UI Automation only returns visible tree view items. Thus, to copy all the items, the find symbol results window is set as foreground, and then a {PGDN} is sent, and the next batch of items is copied. This process is repeated until no new items are found. It would have been preferable to use the ScrollPattern, however it threw an Exception when trying to set the scroll.
Edit 2: Tried to improve the performance of AutomationElement FindAll by running on a separate thread. Seems to be slow in some cases.
Edit 3: Improved performance by making the TreeView window very large. Can copy about 400 items in about 10 seconds.
Edit 4: Dispose objects implementing IDisposable. Better message reporting. Better handling of process args. Put window back to its original size.

I solved this by using Macro Express. They have a free 30-day trial which I used because this is a one-off for me. I wrote a simple macro to copy all of the Find Symbol Results, one line at a time, over into a Notepad document.
Sequence:
* Repeat (x) times (however many symbol results you have)
* Activate Find Symbol Results window
* Delay .5 seconds
* Simulate keystrokes "Arrow Down"
* Clipboard Copy
* Activate Notepad window
* Delay .5 seconds
* Clipboard Paste
* Simulate keystrokes "ENTER"
* End Repeat
Had the same requirement and were solving this by using a screenshot tool named Hypersnap which also has some basic OCR functionality.
If you can encode your symbol as an expression for global Find, then copy-pasting all results from the Find Results window is easy.
eg finding all references of property 'foo' you might do a global find for '.foo'
I'm using Visual Studio 2017 (Version 15.6.4) and it has the functionality directly. Here's an example screenshot (I hit Ctrl+A to select all lines):
The text output for that example is this:
Status Code File Line Column Project
Console.WriteLine(xml); C:\Users\blah\Documents\ConsoleApp1\Program.cs 30 12 ConsoleApp1
static void Console.WriteLine(object)
Console.WriteLine(xml); C:\Users\blah\Documents\ConsoleApp1\Program.cs 18 12 ConsoleApp1
Console.WriteLine(xml); C:\Users\blah\Documents\ConsoleApp1\Program.cs 25 12 ConsoleApp1
I had the same problem. I had to make a list of all the occurences of a certain method and some of its overloaded version.
To solve my problem I used ReSharper. (ReSharper -> Find -> Find Usages Advanced).
It also has a very nice tabulated text export feature.
From my previous experience and a few tests I just did, there is no built in feature to do this.
Why do you want to do this? Why do you want to copy all of the references to the clipboard? As I understand it the speed of these features would make having a static copy of all the references would be relatively useless if you can generate a dynamic and complete copy quickly.
You can always extend visual studio to add this functionality, see
this post at egghead cafe.
Hey Somehow you can achieve this in another way,
Just 'FindAll' the selected text and you will be able to catch all the lines
Visual Studio Code works as a browser.
it is possible to open the developer tools and search for that part of the code
Menu: Help > Toggle Developer tools
write the following instructions to the developer tools console:
var elementos = document.getElementsByClassName("plain match")
console.log(elementos.length)
for(var i = 0; i<elementos.length;i++) console.log(elementos[i].title)
and you can see the match results.
Now if you can copy the results
