Moving a work item between projects in TFS - tfs

Is it possible to move a work item from one project to another inside TFS? I’ve seen a copy option, but no move. Also, if it is possible, what’s the implication for any of the WI history?
I found this article from 2008 that seem to say it's not, but I wondered if there'd been any progress since then.

It isn't possible to move, just copy. The way we do it, is we do the copy, link the original, then close the original as obsolete. You could also create the copy and TF Destroy the original, but you will lose all history.
If you wanted to, you could get very fancy and create your own "move" utility that copies the workitem and all of the history, then closes out (or destroys) the old one. Seems like overkill for something that you probably shouldn't need to do all that often.

Lars Wilhelmsen wrote a WorkItemMigrator -> http://larsw.codeplex.com/SourceControl/list/changesets
Good starting point for a utility you can customize for your needs. We used it to split off a 100 or so work items to a new project. Here's the program I ended up with. Modify the query to subset the items to migrate.

Xamarin.ios: Detail command is null because it shows before function

I'm building an iOS app with Xamarin.ios MvvmCross. And I have a function that puts a random id in a text file every day. So I get a recipe of the day.
The problem is that the code for the Detail command function (for the button) runs before the function that stores everything in the text file. So the detail command returns null and nothing happens when I push the button. The second time I run the code it does what it should do because there's already an id stored in the text file.
The view:
public override void ViewDidLoad()
{
base.ViewDidLoad();
MvxFluentBindingDescriptionSet<TabHomeView, TabHomeViewModel> set = new MvxFluentBindingDescriptionSet<TabHomeView, TabHomeViewModel>(this);
set.Bind(MorningImage).For(img => img.Image).To(res => res.MorningContent.picture).WithConversion<StringToImageConverter>();
set.Bind(MorningJuiceName).To(vm => vm.MorningContent.name);
set.Bind(MorningBtn)
.To(vm => vm.NavigateToMorningJuice);
set.Apply();
}
The function to put a random id in the text file:
public async void GetAfternoonJuice()
{
Recipes = await _recipeService.GetRecipes();
int counter = Recipes.Count;
Random rnd = new Random();
int RandomNumber = rnd.Next(1, counter);
string rndNumToStr = RandomNumber.ToString();
DateTime dateAndTime = DateTime.Now;
string day = dateAndTime.ToString("dd/MM/yyyy");
string folderValue = (day + "," + rndNumToStr);
var _folderName = "TextFilesFolder2";
var _fileName = "AfternoonJuice";
if (!_fileStore.FolderExists(_folderName))
_fileStore.EnsureFolderExists(_folderName);
//Content van de file uitlezen
string value = string.Empty;
_fileStore.TryReadTextFile(_folderName + "/" + _fileName, out (value));
string CheckFileContent = value;
string[] TextFileList;
//Als er niets in zit, default data in steken
if (CheckFileContent == null)
{
_fileStore.WriteFile(_folderName + "/" + _fileName, "00/00/00,0");
string d = "00/00/00,0";
TextFileList = d.Split(',');
}
else
{
TextFileList = CheckFileContent.Split(',');
}
if (TextFileList[0] != day)
{
//File verwijderen om overbodige data te verwijderen.
_fileStore.DeleteFile(_folderName + "/" + _fileName);
//File aanmaken.
if (!_fileStore.FolderExists(_folderName))
_fileStore.EnsureFolderExists(_folderName);
_fileStore.WriteFile(_folderName + "/" + _fileName, folderValue);
string NewValue = string.Empty;
_fileStore.TryReadTextFile(_folderName + "/" + _fileName, out (NewValue));
string NValue = NewValue;
List<string> NewTextFileList = new List<string>(
NValue.Split(new string[] { "," }, StringSplitOptions.None));
int numVall = Int32.Parse(NewTextFileList[1]);
int NewRandomValue = numVall;
AfternoonContent = await _recipeService.GetRecipeById(NewRandomValue);
RaisePropertyChanged(() => AfternoonContent);
}
else
{
int numVall = Int32.Parse(TextFileList[1]);
int NewRandomValue = numVall;
AfternoonContent = await _recipeService.GetRecipeById(NewRandomValue);
RaisePropertyChanged(() => AfternoonContent);
}
}
The detail command:
public MvxCommand<Recipe> NavigateToAfternoonJuice
{
get
{
var _folderName = "TextFilesFolder2";
var _fileName = "AfternoonJuice";
string value = string.Empty;
_fileStore.TryReadTextFile(_folderName + "/" + _fileName, out (value));
string fV = value;
List<string> TextFileList = new List<string>(
fV.Split(new string[] { "," }, StringSplitOptions.None));
int numVall = Int32.Parse(TextFileList[1]);
int NewRandomValue = numVall;
return new MvxCommand<Recipe>(SelectedRecipe =>
{
ShowViewModel<DetailJuiceListViewModel>(new { RecipeId = NewRandomValue });
});
}
}
Some of code in your public property NavigateToAfternoonJuice runs before your command is executed. It will be run, when the binding occurs and not when the command actually executes the body.
You probably want to modify your command to something as follows instead.
private MvxCommand<Recipe> _navigateToAfternoonJuice;
public MvxCommand<Recipe> NavigateToAfternoonJuice
{
get
{
if (_navigateToAfternoonJuice == null)
_navigateToAfternoonJuice = new MvxCommand<Recipe>(DoNavigateToAfternoonJuice);
return _navigateToAfternoonJuice;
}
}
private void DoNavigateToAfternoonJuice(Reciepe selectedRecipe)
{
var _folderName = "TextFilesFolder2";
var _fileName = "AfternoonJuice";
string value = string.Empty;
_fileStore.TryReadTextFile(_folderName + "/" + _fileName, out (value));
string fV = value;
List<string> TextFileList = new List<string>(
fV.Split(new string[] { "," }, StringSplitOptions.None));
int numVall = Int32.Parse(TextFileList[1]);
int NewRandomValue = numVall;
ShowViewModel<DetailJuiceListViewModel>(new { RecipeId = NewRandomValue });
}
This will make the text file to be read when the command executes.

What will be the time complexity of reversing the linked list in a different way using below code?

Given a linked List $link1, with elements (a->b->c->d->e->f->g->h->i->j), we need to reverse the linked list provided that the reversing will be done in a manner like -
Reverse 1st element (a)
Reverse next 2 elements (a->c->b)
Reverse next 3 elements (a->c->b->f->e->d)
Reverse next 4 elements (a->c->b->f->e->d->j->i->h->g)
....
....
I have created below code in PHP to solve this problem
Things I need -
I need to calculate the time complexity of reverseLinkedList function below.
Need to know if we can optimize reverseLinkedList function to reduce time complexity.

It's O(n)...just one traversal.
And secondly, here tagging it in language is not necessary.
I have provided a Pseudocode here for your reference:
current => head_ref
prev => NULL;
current => head_ref;
next => null;
while (current != NULL)
{
next = current->next;
current->next = prev;
prev = current;
current = next;
}
*head_ref = prev;

Check FtpWebResponse.StatusCode before calling response.GetResponseStream(). You are probably having come kind of connection error. My guess would be firewall settings on your Azure VM.

Silverlight 3 File Dialog Box

Ok - I have a WCF Service which reads an excel file from a certain location and strips the data into an object. What I need is the ability to allow users of my program to Upload an excel sheet to the file location that my Service uses.
Alternitivley I could pass the Uploaded excel sheet to the service directly.
Can anyone help with this. My service code is:
public List<ImportFile> ImportExcelData(string FileName)
{
//string dataSource = Location + FileName;
string dataSource = Location;
string conStr = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + dataSource.ToString() + ";Extended Properties=Excel 8.0;";
var con = new OleDbConnection(conStr);
con.Open();
var data = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
var sheetName = data.Rows[0]["TABLE_NAME"].ToString();
OleDbCommand cmd = new OleDbCommand("SELECT * FROM [" + sheetName + "] WHERE Status = '4'", con);
OleDbDataAdapter oleda = new OleDbDataAdapter();
oleda.SelectCommand = cmd;
DataSet ds = new DataSet();
oleda.Fill(ds, "Employees");
DataTable dt = ds.Tables[0];
var _impFiles = new List<ImportFile>();
foreach (DataRow row in dt.Rows)
{
var _import = new ImportFile();
_import.PurchaseOrder = row[4].ToString();
try
{
var ord = row[8].ToString();
DateTime dati = Convert.ToDateTime(ord);
_import.ShipDate = dati;
}
catch (Exception)
{
_import.ShipDate = null;
}
ImportFile additionalData = new ImportFile();
additionalData = GetAdditionalData(_import.PurchaseOrder);
_import.NavOrderNo = additionalData.NavOrderNo;
_import.IsInstall = additionalData.IsInstall;
_import.SalesOrderId = additionalData.SalesOrderId;
_import.ActivityID = additionalData.ActivityID;
_import.Subject = additionalData.Subject ;
_import.IsMatched = (_import.ShipDate != null & _import.NavOrderNo != "" & _import.NavOrderNo != null & _import.ShipDate > DateTime.Parse("01/01/1999") ? true : false);
_import.UpdatedShipToField = false;
_import.UpdatedShipToFieldFailed = false;
_import.CreateNote = false;
_import.CreateNoteFailed = false;
_import.CompleteTask = false;
_import.CompleteTaskFailed = false;
_import.FullyCompleted = 0;
_import.NotCompleted = false;
_impFiles.Add(_import);
}
oleda.Dispose();
con.Close();
//File.Delete(dataSource);
return _impFiles;
}
You will want to modify your service to accept a Stream instead of a filename, then you can save if off to a file (or parse it directly from the Stream, although I don't know how to do that).
Then in your Silverlight app you could do something like this:
private void Button_Click(object sender, RoutedEventArgs ev)
{
var dialog = new OpenFileDialog();
dialog.Filter = "Excel Files (*.xls;*.xlsx;*.xlsm)|*.xls;*.xlsx;*.xlsm|All Files (*.*)|*.*";
if (dialog.ShowDialog() == true)
{
var fileStream = dialog.File.OpenRead();
var proxy = new WcfService();
proxy.ImportExcelDataCompleted += (s, e) =>
{
MessageBox.Show("Import Data is at e.Result");
// don't forget to close the stream
fileStream.Close();
};
proxy.ImportExcelDataAsync(fileStream);
}
}
You could also have your WCF service accept a byte[] and do something like this.
private void Button_Click(object sender, RoutedEventArgs ev)
{
var dialog = new OpenFileDialog();
dialog.Filter = "Excel Files (*.xls;*.xlsx;*.xlsm)|*.xls;*.xlsx;*.xlsm|All Files (*.*)|*.*";
if (dialog.ShowDialog() == true)
{
var length = dialog.File.Length;
var fileContents = new byte[length];
using (var fileStream = dialog.File.OpenRead())
{
if (length > Int32.MaxValue)
{
throw new Exception("Are you sure you want to load > 2GB into memory. There may be better options");
}
fileStream.Read(fileContents, 0, (int)length);
}
var proxy = new WcfService();
proxy.ImportExcelDataCompleted += (s, e) =>
{
MessageBox.Show("Import Data is at e.Result");
// no need to close any streams this way
};
proxy.ImportExcelDataAsync(fileContents);
}
}
Update
Your service could look like this:
public List<ImportFile> ImportExcelData(Stream uploadedFile)
{
var tempFile = HttpContext.Current.Server.MapPath("~/uploadedFiles/" + Path.GetRandomFileName());
try
{
using (var tempStream = File.OpenWrite(tempFile))
{
uploadedFile.CopyTo(tempStream);
}
//string dataSource = Location + FileName;
string dataSource = tempFile;
string conStr = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + dataSource.ToString() +
";Extended Properties=Excel 8.0;";
var con = new OleDbConnection(conStr);
con.Open();
}
finally
{
if (File.Exists(tempFile))
File.Delete(tempFile);
}
}
Thanks Bendewey that was great. Had to amend it slightly -
My Service:
var tempFile = #"c:\temp\" + Path.GetRandomFileName();
try
{
int length = 256;
int bytesRead = 0;
Byte[] buffer = new Byte[length];
// write the required bytes
using (FileStream fs = new FileStream(tempFile, FileMode.Create))
{
do
{
bytesRead = uploadedFile.Read(buffer, 0, length);
fs.Write(buffer, 0, bytesRead);
}
while (bytesRead == length);
}
uploadedFile.Dispose();
string conStr = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + dataSource.ToString() + ";Extended Properties=Excel 8.0;";
var con = new OleDbConnection(conStr);
Thanks Again for your help
