I have created my first dll using c# and visual studio 2010. I am trying to use it in a program. The dll is in the program directory but visual studio will not allow using myDLL stating that it could not be found. I have also tried adding it as a reference in the solution explorer. What more do I need to do?
Here is one of the files from my class.
namespace nbt
{
class TAG_Long
{
private string name;
private long payload;
public TAG_Long(FileStream f)
{
name = NameTag.SetTagName(f);
byte[] buffer = new byte[(int)dataBytes.TYPE_LONG];
f.Read(buffer, 0, (int)dataBytes.TYPE_LONG);
Array.Reverse(buffer);
payload = BitConverter.ToInt64(buffer, 0);
}
}
}
Try putting your class in a namespace

I have a project in Visual Studio 2010 with target to framework 3.5 with some code like this:
public class Test {
private object _field;
private Action defaultAction = null;
public Test(Action a)
{
defaultAction = a;
}
public Test()
: this(() => { _field = new object(); })
{
}
}
When I compile the project from the VS reports a compile error at line 11.
When I compile the project from the command line with "C:\Windows\Microsoft.NET\Framework\v3.5\msbuild.exe Test.sln" compiles successfully.
In fact this code compiles in VS2008 but in VS2010 with target to framework 3.5, doesn't.
Any idea about what is happend?
Update
To fix the code in V2010 I changed as follows (this is equivalent to origian code):
public class Test {
private object _field;
private Action defaultAction = null;
public Test(Action a)
{
defaultAction = a;
}
public Test()
{
defaultAction = () => {_field = new object();}
}
}
But what worries me is that Visual Studio is compiling my code with framework 4.0 and this may cause other errors when deploying my application in the customer's environment (framework 3.5).
I don't have access to VS2008 or .NET 3.5 at the moment so I can't investigate why it's compiling for you. There might be an explanation linked from What's New in the .NET Framework 4
What I can offer however is a fix to get it compiling in VS2010. By declaring _field as static, an instance of it will be available in the constructor of the Test class.
Replace the second line of your posted code with this and the code should compile:
private static object _field;
I am in the process of writing a custom editor for visual studio. I have implemented some basic functionality for the new language e.g. syntax highlighting and I succesfully installed tha package by using the generated .vsix file. All works just nice, however my custom editor needs to be able to be associated with different file extensions.
I thought, mistakenly, that since I installed the editor it would appear under
Tools->Options..->Text Editor->File Extension->Editors list:
However it does not appear there. So the question is: how do you add a custom editor to this list?
Thanks for any help!
Well at least I got the tumbleweed badge for this question.
After a lot of reverse engineering I found the solution... which is not documented.. Anywhere..
Step number 1:
First you need to create an editor factory with all the bells and whistles it comes with - MSVS has an extension for it.
Step number 2:
Then you have to create such a class
[AttributeUsage(AttributeTargets.Class, AllowMultiple = true, Inherited = true)]
class ProvideFileExtensionMapping : RegistrationAttribute
{
private readonly string _name, _id, _editorGuid, _package;
private readonly int _sortPriority;
public ProvideFileExtensionMapping(string id, string name, object editorGuid, string package, int sortPriority)
{
_id = id;
_name = name;
if (editorGuid is Type)
{
_editorGuid = ((Type)editorGuid).GUID.ToString("B");
}
else
{
_editorGuid = editorGuid.ToString();
}
_package = package;
_sortPriority = sortPriority;
}
public override void Register(RegistrationContext context)
{
using (Key mappingKey = context.CreateKey("FileExtensionMapping\\" + _id))
{
mappingKey.SetValue("", _name);
mappingKey.SetValue("DisplayName", _name);
mappingKey.SetValue("EditorGuid", _editorGuid);
mappingKey.SetValue("Package", _package);
mappingKey.SetValue("SortPriority", _sortPriority);
}
}
public override void Unregister(RegistrationAttribute.RegistrationContext context)
{
}
}
Step 3:
Then you need to add this class as an attribute to your editor factory (which you created in step 1):
[ProvideFileExtensionMapping("{E23E32ED-3467-4401-A364-1352666A3502}", "RText Editor", typeof(EditorFactory), GuidList.guidRTextEditorPluginEditorFactoryString, 100)]
public sealed class EditorFactory : IVsEditorFactory, IDisposable{...}
That's it. You should now be able to see your editor in the list of editors in visual studio.
Your editor shall be invoked when the file mapping is right.
Hopefully this post saves a lot of time for someone else..
I am wondering if anyone knows an extension that pops up a warning if you drag a file to another folder through VS 2010 solution explorer. Many times I will be on a file and my computer may lag for a second and all of a sudden the file is now in some other folder and I may not even notice it.
There is a Visual Studio extension available called VSCommands 2010 which has a feature Prevent accidental Drag & Drop in Solution Explorer.
Edit
The feature is part of the Pro package which is not free.
I don't know of a free Visual Studio extension that would do it, but here is a C# sample of an Addin that demonstrate how to hook into Visual Studio global remove & rename file management. It's based on the IVsTrackProjectDocumentsEvents2 interface.
You would have to extend the two OnQueryxxx methods to suit your needs.
using System;
using System.Diagnostics;
using EnvDTE;
using EnvDTE80;
using Extensibility;
using Microsoft.VisualStudio.Shell;
using Microsoft.VisualStudio.Shell.Interop;
namespace MyAddin1
{
public class Connect : IDTExtensibility2, IVsTrackProjectDocumentsEvents2
{
private uint _trackerCookie;
public void OnConnection(object application, ext_ConnectMode connectMode, object addInInst, ref Array custom)
{
_applicationObject = (DTE2)application;
_addInInstance = (AddIn)addInInst;
// the Addin project needs assembly references to Microsoft.VisualStudio.Shell, Microsoft.VisualStudio.Shell.Interop && Microsoft.VisualStudio.OLE.Interop
// any version should do
ServiceProvider sp = new ServiceProvider((Microsoft.VisualStudio.OLE.Interop.IServiceProvider)_applicationObject);
IVsTrackProjectDocuments2 tracker = (IVsTrackProjectDocuments2)sp.GetService(typeof(SVsTrackProjectDocuments));
// ask VS to notify us of files & directories changes
tracker.AdviseTrackProjectDocumentsEvents(this, out _trackerCookie);
}
public void OnDisconnection(ext_DisconnectMode disconnectMode, ref Array custom)
{
if (_trackerCookie != 0)
{
// we quit, tell VS not to notify us anymore
ServiceProvider sp = new ServiceProvider((Microsoft.VisualStudio.OLE.Interop.IServiceProvider)_applicationObject);
IVsTrackProjectDocuments2 tracker = (IVsTrackProjectDocuments2)sp.GetService(typeof(SVsTrackProjectDocuments));
tracker.UnadviseTrackProjectDocumentsEvents(_trackerCookie);
_trackerCookie = 0;
}
}
public int OnQueryRenameFiles(IVsProject pProject, int cFiles, string[] rgszMkOldNames, string[] rgszMkNewNames, VSQUERYRENAMEFILEFLAGS[] rgFlags, VSQUERYRENAMEFILERESULTS[] pSummaryResult, VSQUERYRENAMEFILERESULTS[] rgResults)
{
Trace.WriteLine("OnQueryRenameFiles pProject:" + pProject + " old[0]:" + rgszMkOldNames[0] + " new[0]:" + rgszMkNewNames[0]);
// TODO: implement this (I have assumed cFiles is 1 here)
if (!NotRenameOk(old[0], new[0])
{
rgResults[0] = VSQUERYRENAMEFILERESULTS.VSQUERYRENAMEFILERESULTS_RenameNotOK; // nope, it's not ok
}
return 0;
}
public int OnQueryRemoveFiles(IVsProject pProject, int cFiles, string[] rgpszMkDocuments, VSQUERYREMOVEFILEFLAGS[] rgFlags, VSQUERYREMOVEFILERESULTS[] pSummaryResult, VSQUERYREMOVEFILERESULTS[] rgResults)
{
Trace.WriteLine("OnQueryRemoveFiles pProject:" + pProject + " file[0]:" + rgpszMkDocuments[0]);
// TODO: needs to be implemented, use rgResults to tell VS if it's ok or not
return 0;
}
// other IVsTrackProjectDocumentsEvents2 methods implementation omitted for brevity...
I'm currently developping a Visual Studio Extension and I have a question about Options Page. Options Page allows user to save setting about your Extension. Visual Studio handle a lot of work for us.
I created the Options Page.
public class VisualStudioParameter : DialogPage
{
private string _tfsServerUrl = DefaultParameter.TfsServerUrl;
[Category("TFS Parameters")]
[DisplayName(#"Server Name")]
[Description("The URL of your TFS Server")]
public string TfsServerUrl
{
get { return _tfsServerUrl; }
set { _tfsServerUrl = value; }
}
}
First, I created a method in the Visual Studio Package to acces to the Options Page.
Okay so now, from my Package, I can easily acces to the settings.
partial class SpecFlowTfsLinkerExtensionPackage : Package : IParameter
{
....
....
public string GetTfsServerUrl()
{
return ((VisualStudioParameter) GetDialogPage(typeof (VisualStudioParameter))).TfsServerUrl;
}
}
Now, I want to be able, in another library (Another project, included in the VSIX Package), to get easily these values. I don't want to reference the Visual Studio AddIn Package in my library.
I also have Unit Test so I'm going to create an Interface. During Unit Test, I going to Mock the object.
public interface IParameter
{
string GetTfsServerUrl();
}
Do you have any idea about how I can develop a clean solution to get these parameters from another assembly ?
Do you think the better solution is to inject the AddIn dependency in my library ?
If you already developed a Visual Studio Extension, How did you encapsulated the user setting from your core assembly ?
Thanks a lot.
You can try something like that:
// Access DTE infrastructure
EnvDTE.DTE dte = Microsoft.VisualStudio.Shell.Package.GetGlobalService(typeof(EnvDTE.DTE)) as EnvDTE.DTE;
// Access options page
var props = dte.get_Properties(#"Your Extension", "General");
var pathProperty = props.Item("TfsServerUrl");
path = pathProperty.Value as string;
From a visual studio package (VSIX) how do I detect a solution or project build?
If you have a Package class in your assembly, you can do:
DTE2 = Package.GetGlobalService(typeof(SDTE)) as DTE2;
Then look at then IsOpen property, to see if the solution is open... the look at the Projects property to find the projects.
However, if you mean you how do I get an event when a solution is opened... then Solutions, for example:
public sealed class MyPackage : Package
{
private DTE m_dte;
protected override void Initialize()
{
IServiceContainer serviceContainer = this as IServiceContainer;
m_dte = serviceContainer.GetService(typeof(SDTE)) as DTE;
var m_solutionEvents = m_dte.Events.SolutionEvents;
m_solutionEvents.Opened += SolutionOpened;
...
}
void SolutionOpened()
{
.... away you go...
}
}

Have a look at DTE.Events.BuildEvents there are events for OnBuildBegin and OnBuildDone.
