Rename TFS Branch Programaticly c# (TFS2017)

I'm trying to rename a branch programaticly using "PendRename" method from Microsoft.TeamFoundation.VersionControl.Client.
Moves working, so, if I use this to move everything to a new location, it works, but what I need is to rename a branch.
It is possible to do this by commandline "tfs.exe rename " (even this is given me errors if I have more than one workspace mapped for the same server url. the ... could not be found in your workspace, or you do not have permission to access it.)
So, could you please help to understand why rename a branch is not working?
Thank you,

To Rename or move files and folders in TFVC, you must be one of the Contributors for your team project. See Team Foundation Server default groups, permissions, and roles.
I tested that and renamed the branch correctly with the "PendRename" method.
Below code sample for your reference:
using System;
using Microsoft.TeamFoundation.Client;
using Microsoft.TeamFoundation.VersionControl.Client;
namespace RenameBranch
{
class Program
{
static void Main(string[] args)
{
string oldPath = #"E:\andy\0418Scrum\web0418-0823";
string newPath = #"E:\andy\0418Scrum\web0418-1020";
string collection = #"http://server:8080/tfs/DefaultCollection";
var tfsServer = new Uri(collection);
var tpc = new TfsTeamProjectCollection(tfsServer);
var vcs = tpc.GetService<VersionControlServer>();
Workspace workspace = vcs.GetWorkspace("YourWorkspaceName", vcs.AuthorizedUser);
workspace.PendRename(oldPath, newPath);
}
}
}
Then you need CheckIn it of course. Use a "workspace.GetPendingChanges()" and "workspace.CheckIn()" methods to do it.

Thank you,
The problem was, there are different processes that are generating workspaces to the directory, and then, he can't remove it.
So, I solve this issue doing this steps:
1. reserve a workspace local location for my app´
2. see if this workspace is mapped. If yes, I remove it
3. create a workspace to the previous folder in path and create the map
4. get latest
5. rename
Thank you Andy-MSFT for your support.

Trying to get an Eventlog file to be copied to another folder for backup purpose

I try to copy the EventLog "Application" to another folder on my PC but always get the error that
"....Could not find a part of the path
'C:\Windows\System32\winevt\Logs\Application.evtx..."
I use the code:
public void collectEventLogsFromSystem(string RequestedlogName,string newFolderPath)
{
string combinedLogToFind = "HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\Eventlog\\" + RequestedlogName;
string LogEventsPath = (string)Registry.GetValue(combinedLogToFind, "File", null);
if (LogEventsPath != null)
{
System.IO.File.Copy(LogEventsPath, newFolderPath +"\\"+ RequestedlogName, true);
}
}//collectEventLogsFromSystem method
Even if i use explicit folder path it won't work:
System.IO.File.Copy(#"C:\Windows\System32\winevt\Logs\Application.evtx", "c:\\ttt\\Application.evtx", true);
any idea?

I found this answer on StackOverflow which will probably solve your problem. I have a 64 bit machine which exhibited the same behavior. This post by John Rasch solved the issue and explains why it failed.

If you are trying to get the log file while the program is running, the way above will not work. This post Export Event Log (.evtx) without "run as administrator" will allow you to backup the event log, even if you are currently using the event log in your application.

Saving image to a folder in IIS localhost

I have to save images to a folder located in "c:\inetpub\wwwroot\" and named as "UploadedImages". Here is my code:
public string SaveImage(string base64,int compno)
{
string res = "";
try
{
using (MemoryStream ms = new MemoryStream(Convert.FromBase64String(base64)))
{
using (Bitmap bm2 = new Bitmap(ms))
{
bm2.Save(Server.MapPath("~/UploadedImages/ID"+compno+".jpg"));
}
}
res = "done";
}
catch (Exception ex) {
res = ex.ToString();
}
return res;
}
but it throws "A generic error occured in GDI+ at System.Drawing.Image.Save" exception. What am I doing wrong? This code works fine when saving image locally as
bm2.Save("D:Embasy\UploadedImages\ID"+compno+".jpg"));
What changes do I need to make to save images in localhost directory?

Your not going to believe this -- the site running v1.1 had a virtual directory set-up which was mapped to the directory in which the image was saved to -- things worked fine.
The v2.0 site also had the same virtual directory name, but the physical path was different -- I changed the path to point to the same directory as the v1.0 site and now the code works.
So in short -- you were right about the "path must exist".
Classes within the System.Drawing namespace are not supported for use within a Windows or ASP.NET service. Attempting to use these classes from within one of these application types may produce unexpected problems, such as diminished service performance and run-time exceptions. For a supported alternative, see Windows Imaging Components.

When you are using Server.Mappath
bm2.Save(Server.MapPath("~/UploadedImages/ID"+compno+".jpg"));
"~(tield)" : is point to project/application root folder c:\inetpub\wwwroot\yourproject
then find remaining your path /UploadedImages and then create ID1.jpg.
But your imagefolder "UploadImages" is exist in d: not in c:\inetpub\wwwroot\yourproject
if you want to exist your image folder in D: then you should to create
virtual directory and then you need to apply path as relevant

My problem actually was that every time i published website, I replaced the "UploadedImages" folder too and thus permissions were changed. So, i didnt replaced the folder again after changing its permissions and creating "everyone" group and giving full rights to it. Now code is working perfectly :)

Why can't I programatically replace perfc009.dat in windows 7?

We have an application that uses the Windows 7 performance counters to track the total CPU usage. Every so often the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\009 will become corrupted and just be empty.
Manually following the steps found here http://support.microsoft.com/kb/300956 works perfectly. But when I make a C# program to programatically replace the 2 files mentioned no errors, exceptions, etc. But the files are not saved to the proper directory.
Here's what I've been using to test:
static void Main(string[] args)
{
string fileToReadPath1 = #"perfc009.dat";
string fileToReadPath2 = #"perfh009.dat";
FileInfo fileToRead1 = new FileInfo(fileToReadPath1);
FileInfo fileToRead2 = new FileInfo(fileToReadPath2);
FileInfo fileToReplaceInfo1 = new FileInfo(#"C:\Windows\System32\perfc009.dat");
FileInfo fileToReplaceInfo2 = new FileInfo(#"C:\Windows\System32\perfh009.dat");
File.Copy(fileToRead1.FullName, fileToReplaceInfo1.FullName, true);
File.Copy(fileToRead2.FullName, fileToReplaceInfo2.FullName, true);
}
I do make sure to run it with Administrative privileges.
Anyone know why the program would seem to run fine, but not copy the files to that directory? Is there some Windows security thing stopping this?

Thanks to Mike Z and the link shared in the comments above. Turns out because I was running in a 32-bit process, the OS did not allow it to edit those files. Compiling to 64-bit did work.

Image path file not found

I have spent quite a while trying to solve this problem, but to no avail. I have searched stackoverflow as well as Google and have not been able to resolve my (seemingly) simple problem.
I am getting a FileNotFoundException in the following line:
Image.FromFile("\\Resources\\Icons\\key-icon.png");
The folders and image are really there, and I can't see what the problem is.

You should consider that it is started from "yourproject/bin/Release" so you need to go up 2 directories. Do this:
Image.FromFile("..\\..\\Resources\\Icons\\key-icon.png");

Try using an absolute path not a relative one... i.e.
Image.FromFile(Server.MapPath(#"~\Resources\Icons\key-icon.png"));

Image.FromFile(Path.Combine(AppDomain.CurrentDomain.BaseDirectory,
#"Resources\\Icons\\key-icon.png"))
Base-directory Combine your file-name

You may be missing a leading ".":
Image.FromFile(".\\Resources\\Icons\\key-icon.png");

Internally, Image.FromFile uses File.Exists to check whether the file exists. This method returns false when:
the file does not exist (makes sense)
the current process identity does not have permission to read the file
It may be that the second option is your problem.
And another possibility: is Resources a network share? In that case you should use the following:
Image.FromFile("\\\\Resources\\Icons\\key-icon.png");

For this case I discovered that sikuli does not automatically detect the root folder of the project. What you should do for this case is specify the folder using the command System.getProperty("user.dir");
import org.sikuli.script.*;
public class Test {
public static void main(String[] args) {
Screen s = new Screen();
try{
String pathYourSystem = System.getProperty("user.dir") + "\\";
s.click(pathYourSystem + "imgs/spotlight.png");
//s.wait(pathYourSystem + "imgs/spotlight-input.png");
//s.click();
s.write("hello world#ENTER.");
}
catch(FindFailed e){
e.printStackTrace();
}
}
}
