Develop Reference

Getting Value cannot be null. parameter name: source on release but not in debug

I'm creating a Revit plugin that reads and writes modelinformation to a database, and it all works fine in debug mode, but when I release the project and run Revit with the plugin outside visual studio, I'm getting an error when the plugin tries to read data from the database.
The code runs on DocumenetOpened event and looks like this:
public void application_DocumentOpenedEvent(object sender, DocumentOpenedEventArgs e)
{
UIApplication uiapp = new UIApplication(sender as Autodesk.Revit.ApplicationServices.Application);
Document doc = uiapp.ActiveUIDocument.Document;
//ModelGUID COMMAND
var command = new ModelCheckerCommandExec();
command.Execute(uiapp);
}
It then fails on the following line:
ModelsList = (DatabaseHelper.ReadNonAsync<RevitModel>())
.Where(m => m.ModelGUID == DataStores.ModelData.ModelGUID).ToList();
In this code block that gets executed:
public class ModelCheckerCommandExec : IExternalCommand
{
public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
{
return Execute(commandData.Application);
}
public Result Execute(UIApplication uiapp)
{
Document doc = uiapp.ActiveUIDocument.Document;
Transaction trans = new Transaction(doc);
try
{
trans.Start("ModelGUID");
ModelGUIDCommand.GetAndSetGUID(doc);
trans.Commit();
var ModelsList = new List<RevitModel>();
ModelsList = (DatabaseHelper.ReadNonAsync<RevitModel>()).ToList();//.Where(m => m.ModelGUID == DataStores.ModelData.ModelGUID).ToList(); // Read method only finds models the are similar to the DataStore.ModelDate.DBId;
if (ModelsList.Count == 1)
{
trans.Start("DataFromDB");
doc.ProjectInformation.Name = ModelsList[0].ProjectName;
doc.ProjectInformation.Number = ModelsList[0].ModelNumber;
doc.ProjectInformation.Status = ModelsList[0].ModelStatus;
doc.ProjectInformation.IssueDate = ModelsList[0].ProjectIssueDate;
doc.ProjectInformation.ClientName = ModelsList[0].ClientName;
doc.ProjectInformation.Address = ModelsList[0].ProjectAddress;
doc.ProjectInformation.LookupParameter("Cadastral Data").Set(ModelsList[0].ProjectIssueDate);
doc.ProjectInformation.LookupParameter("Current Version").Set(ModelsList[0].CurrentVersion);
doc.ProjectInformation.BuildingName = ModelsList[0].BuildingName;
DataStores.ModelData.ModelManager1 = ModelsList[0].ModelManagerOne;
DataStores.ModelData.ModelManager1Id = ModelsList[0].ModelManagerOneId;
DataStores.ModelData.ModelManager2 = ModelsList[0].ModelManagerTwo;
DataStores.ModelData.ModelManager2Id = ModelsList[0].ModelManagerTwoId;
trans.Commit();
}
return Result.Succeeded;
}
catch (Exception ex)
{
TaskDialog.Show("Error", ex.Message);
return Result.Failed;
}
}
}
The "ReadNonAsync" method is as follows:
public static List<T> ReadNonAsync<T>() where T : IHasId
{
using (var client = new HttpClient())
{
var result = client.GetAsync($"{dbPath}{Properties.Settings.Default.CompanyName}_{typeof(T).Name.ToLower()}.json?access_token={DataStores.IdToken.UserIdToken}").GetAwaiter().GetResult();
var jsonResult = result.Content.ReadAsStringAsync().GetAwaiter().GetResult();
if (result.IsSuccessStatusCode)
{
var objects = JsonConvert.DeserializeObject<Dictionary<string, T>>(jsonResult);
List<T> list = new List<T>();
if (objects != null)
{
foreach (var o in objects)
{
o.Value.Id = o.Key;
list.Add(o.Value);
}
}
return list;
}
else
{
return null;
}
}
}
In the rest of my code I use a async Read method which works, so I'm wondering wether or not that's the issue, but Revit wont let me use an async method inside an Execute method.
How do I debug this issue correctly, and why could there be code working in debug that doesn't work in "live" versions?

I found a solution!
The issue:
The reason for the error was that when I run the software in debug-mode, a file path of "xxx.txt" finds files in the solution folder, but when I run the software "xxx.txt" points to the folder of the software and not the .dll -
So in my case it pointed to "c:\Program Files\Autodesk\Revit\2021".
The fix:
Hard coding the path, or by getting the path of the executing .dll
Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location)
Debugging/Troubleshooting:
I found the issue by inserting dialogboxes with errormessages in all my try/catch statements.

And the file abc.docx after sign :
In the Additional Information of the signature , the system date/time(sign time) is diferrent from my local time and the date/time format too.I try to change my local time zone and reset date/time but it still not work.
What am i missing?

C# / VBS Automate Team Project Creation in TFS 2015 Update 3

I'm looking for a way to automate team project creation in TFS 2015 Update 3.
I did a quick crawl over the web and found various posts on how to do it but nothing specific to 2015 version update 3.
Some links I found:
#1
#2
I'd like to do it as simple and lightweight as possible.
A rough idea would be to fill up all the details needed e.g.:
Sign in details, server, collection, project name, etc... on an excel, save the information somewhere (like an xml for presented on link#2) and trigger a batch file to do the necessary stuff via vbs macro.
To be honest I do not know where to start yet, like how to even automate the project creation part.
Appreciate if you can point me in the right path to start this out. Ideas are also welcome :). Thanks in advance!

You could use this REST API to create a team project. TFS also provide to using C# code to create a team project:
public static TeamProject CreateProject()
{
string projectName = "Sample project";
string projectDescription = "Short description for my new project";
string processName = "Agile";
VssCredentials c = new VssCredentials(new Microsoft.VisualStudio.Services.Common.WindowsCredential(new NetworkCredential("username", "password", "domain")));
VssConnection connection = new VssConnection(new Uri("http://v-tinmo-12r2:8080/tfs/MyCollection"),c);
// Setup version control properties
Dictionary<string, string> versionControlProperties = new Dictionary<string, string>();
versionControlProperties[TeamProjectCapabilitiesConstants.VersionControlCapabilityAttributeName] =
SourceControlTypes.Git.ToString();
// Setup process properties
ProcessHttpClient processClient = connection.GetClient<ProcessHttpClient>();
Guid processId = processClient.GetProcessesAsync().Result.Find(process => { return process.Name.Equals(processName, StringComparison.InvariantCultureIgnoreCase); }).Id;
Dictionary<string, string> processProperaties = new Dictionary<string, string>();
processProperaties[TeamProjectCapabilitiesConstants.ProcessTemplateCapabilityTemplateTypeIdAttributeName] =
processId.ToString();
// Construct capabilities dictionary
Dictionary<string, Dictionary<string, string>> capabilities = new Dictionary<string, Dictionary<string, string>>();
capabilities[TeamProjectCapabilitiesConstants.VersionControlCapabilityName] =
versionControlProperties;
capabilities[TeamProjectCapabilitiesConstants.ProcessTemplateCapabilityName] =
processProperaties;
//Construct object containing properties needed for creating the project
TeamProject projectCreateParameters = new TeamProject()
{
Name = projectName,
Description = projectDescription,
Capabilities = capabilities
};
// Get a client
ProjectHttpClient projectClient = connection.GetClient<ProjectHttpClient>();
TeamProject project = null;
try
{
Console.WriteLine("Queuing project creation...");
// Queue the project creation operation
// This returns an operation object that can be used to check the status of the creation
OperationReference operation = projectClient.QueueCreateProject(projectCreateParameters).Result;
// Check the operation status every 5 seconds (for up to 30 seconds)
Operation completedOperation = WaitForLongRunningOperation(connection, operation.Id, 5, 30).Result;
// Check if the operation succeeded (the project was created) or failed
if (completedOperation.Status == OperationStatus.Succeeded)
{
// Get the full details about the newly created project
project = projectClient.GetProject(
projectCreateParameters.Name,
includeCapabilities: true,
includeHistory: true).Result;
Console.WriteLine();
Console.WriteLine("Project created (ID: {0})", project.Id);
}
else
{
Console.WriteLine("Project creation operation failed: " + completedOperation.ResultMessage);
}
}
catch (Exception ex)
{
Console.WriteLine("Exception during create project: ", ex.Message);
}
return project;
}
private static async Task<Operation> WaitForLongRunningOperation(VssConnection connection, Guid operationId, int interavalInSec = 5, int maxTimeInSeconds = 60, CancellationToken cancellationToken = default(CancellationToken))
{
OperationsHttpClient operationsClient = connection.GetClient<OperationsHttpClient>();
DateTime expiration = DateTime.Now.AddSeconds(maxTimeInSeconds);
int checkCount = 0;
while (true)
{
Console.WriteLine(" Checking status ({0})... ", (checkCount++));
Operation operation = await operationsClient.GetOperation(operationId, cancellationToken);
if (!operation.Completed)
{
Console.WriteLine(" Pausing {0} seconds", interavalInSec);
await Task.Delay(interavalInSec * 1000);
if (DateTime.Now > expiration)
{
throw new Exception(String.Format("Operation did not complete in {0} seconds.", maxTimeInSeconds));
}
}
else
{
return operation;
}
}
}

"Access to path [...] is denied" even when I Run as Administrator

My program is not liking my File.Copy, as it says
Access to the path 'C:\Users\Me\Documents\Visual Studio
2013\Projects\Unfriendly\Unfriendly\bin\Debug\Data' is denied
when I try to invoke my function
public void AddFriendList ( string newDataPath )
{
// dataPath: Full file path to Facebook data file being added
string newFriendsPath = System.IO.Path.Combine(new string [] { newDataPath,"html","friends.htm"});
using ( StreamReader sr = new StreamReader(this._datadir) )
{
Match friendsULs = DataReader._lregx.Match(sr.ReadToEnd());
if ( !friendsULs.Success )
{
throw new Exception(String.Format("Couldn't find exactly one piece of HTML matching regex {0}",
DataReader._lregx.ToString()));
}
Dictionary<string, int> friendMap = new Dictionary<string, int>();
foreach ( Match thisFriendRegex in DataReader._fregx.Matches(friendsULs.ToString()) )
{
var thisFriendString = thisFriendRegex.ToString();
if ( friendMap.ContainsKey(thisFriendString) )
{
++friendMap[thisFriendString];
}
else
{
friendMap[thisFriendString] = 1;
}
_fhist.Add(new FriendList { friendNames = friendMap, timestamp = File.GetCreationTime(newFriendsPath) });
}
}
// Copy new data Facebook data into repository
File.Copy(newDataPath, this._datadir);
}
with newDataPath being C:\Users\Me\Desktop\facebook_data. I've tried Run as Administrator and still get the error.
The full meat of my project can be seen at https://github.com/jamkin/Unfriendly/blob/master/Unfriendly/DataReader.cs and, by the way, it looks like GitHub doesn't know what to do with #"..." strings since it's making everything blue after
private static readonly string _instructsBody = String.Format(#"AddFriendList <FacebookDataPath>: Adds to reposistory the instance of Facebook data found at FacebookDataPath\n
Example usage: AddFriendList C:\Users\Jamin\Desktop\facebook_data_1\n
{0}\n
PrintInstructions: Prints instructions (like you just did!)\n
{0}\n
CompareLastTwo: Shows difference between latest two friends lists in repository",
new String('-', DataReader._instructsHeader.Length));
Is there a way to write that and not confuse GitHub?

in this code i am trying to build a list of urls to be used as autoComplete source later.
what i am doing wrong is notc onditioning on adding the parsed values into the dictionary .
i need to find a way to add domain name as the key, even if already exist,
so i would like to be able to make a condition :
if the key in this dictionary already exists, add collection index of current link to string.value of key as a suffix
or if you would like to suggest a different solution all together... i will be happy to see new example.
thanks

I think what you want, rather than a Dictionary<string, string>, is a Dictionary<string, HashSet<string>>. That way, you can build a list of URLs for each domain. Your code to add an item to the list would be:
var UrlVal= link.Attributes["href"].Value;
var name = UrlVal.Split('.')[1];
// get links for this host
HashSet hostLinksList;
if (!LnksDict.TryGetValue(name, out hostLinksList))
{
hostLinksList = new HashSet<string>();
LnksDict.Add(name, hostLinksList);
}
// add the URL to the list of links for this host
hostLinksList.Add(UrlVal);
The key here is that calling Add on a HashSet when the item is already there won't throw an exception. It just doesn't add it again and returns false to indicate that the item was already in the collection.
When you're done, you have a list of URLs for each host (domain), which you can then use for your auto completion.
By the way, your method of splitting out the host using Split('.') isn't going to work very well. It assumes domains of the form "www.example.com". If you run into, for example, "example.com" (without the "www"), you're going to get "com" for the name. Also, "www.example.com" is going to collide with "www.example.org" and "www.example.co.uk". You need a better way of identifying hosts.
