Creating a Visual Studio menu command to get current active file path

I am trying to create a 2017 VS extension with a button command that will display the file path of the current active file. I have followed this https://learn.microsoft.com/en-us/visualstudio/extensibility/extensibility-hello-world?view=vs-2017#prerequisites and have already created the extention but I cannot seem to get the file path of the active file.

if (!IsSingleProjectItemSelection(out hierarchy, out itemid)) return;
// Get the file path
string itemFullPath = null;
((IVsProject) hierarchy).GetMkDocument(itemid, out itemFullPath);
var transformFileInfo = new FileInfo(itemFullPath);
string fullPath = transformFileInfo.FullName;
public static bool IsSingleProjectItemSelection(out IVsHierarchy hierarchy, out uint itemid)
{
hierarchy = null;
itemid = VSConstants.VSITEMID_NIL;
int hr = VSConstants.S_OK;
var monitorSelection = Package.GetGlobalService(typeof(SVsShellMonitorSelection)) as
IVsMonitorSelection;
var solution = Package.GetGlobalService(typeof(SVsSolution)) as IVsSolution;
if (monitorSelection == null || solution == null)
{
return false;
}
IVsMultiItemSelect multiItemSelect = null;
IntPtr hierarchyPtr = IntPtr.Zero;
IntPtr selectionContainerPtr = IntPtr.Zero;
try
{
hr = monitorSelection.GetCurrentSelection(out hierarchyPtr, out itemid, out multiItemSelect, out selectionContainerPtr);
if (ErrorHandler.Failed(hr) || hierarchyPtr == IntPtr.Zero || itemid == VSConstants.VSITEMID_NIL)
{
// there is no selection
return false;
}
// multiple items are selected
if (multiItemSelect != null) return false;
// there is a hierarchy root node selected, thus it is not a single item inside a project
if (itemid == VSConstants.VSITEMID_ROOT) return false;
hierarchy = Marshal.GetObjectForIUnknown(hierarchyPtr) as IVsHierarchy;
if (hierarchy == null) return false;
Guid guidProjectID = Guid.Empty;
if (ErrorHandler.Failed(solution.GetGuidOfProject(hierarchy, out guidProjectID)))
{
return false; // hierarchy is not a project inside the Solution if it does not have a ProjectID Guid
}
// if we got this far then there is a single project item selected
return true;
}
finally
{
if (selectionContainerPtr != IntPtr.Zero)
{
Marshal.Release(selectionContainerPtr);
}
if (hierarchyPtr != IntPtr.Zero)
{
Marshal.Release(hierarchyPtr);
}
}

How to get the correct active Application from a VBE-Add-In?

I'm writing a COM add-in for the VBE of access and I want to execute a vba-function out of C# after clicking a commandbar button.
So I use the following code:
const string ApplicationObjectName = "Access.Application";
Microsoft.Office.Interop.Access.Application app = (Microsoft.Office.Interop.Access.Application)Marshal.GetActiveObject(ApplicationObjectName);
app.Run(functionName);
This works fine if there is only one ms-access-db open. But if there are two open databases, ´GetActiveObject´ gets the wrong application and the function is called in the other database. Not in the one the commandbar button is part of.
So, how do I get the correct application object (= the one the button is clicked in)?

At the moment I use the snippet from here (german only):

Getting the active url of browser in C# windows form application

I have created a window form application.
This App get the active url of browser and save this into the text file.
And this works fine in chrome & IE.
But when i use firefox, this will not work. This code fails to get the active url of firefox browser.
I don't know why this happening.
I am using the following code to find the URL
public string GetBrowsedUrl()
{
IntPtr hwnd = APIFuncs.getforegroundWindow();
Int32 pid = APIFuncs.GetWindowProcessID(hwnd);
Process process = Process.GetProcessById(pid);
string appId = proc.Id.ToString();
string appName = proc.ProcessName;
string appltitle = APIFuncs.ActiveApplTitle().Trim().Replace("\0", "");
if (process == null)
throw new ArgumentNullException("process");
if (process.MainWindowHandle == IntPtr.Zero)
return null;
AutomationElement element = AutomationElement.FromHandle(process.MainWindowHandle);
if (element == null)
return null;
AutomationElement edit = element.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));
string result = ((ValuePattern)edit.GetCurrentPattern(ValuePattern.Pattern)).Current.Value as string;
return result;
}

Finally i found the answer
public string GetBrowsedUrl(Process process)
{
if (process.ProcessName == "firefox")
{
if (process == null)
throw new ArgumentNullException("process");
if (process.MainWindowHandle == IntPtr.Zero)
return null;
AutomationElement element = AutomationElement.FromHandle(process.MainWindowHandle);
if (element == null)
return null;
AutomationElement doc = element.FindFirst(TreeScope.Subtree, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document));
if (doc == null)
return null;
return ((ValuePattern)doc.GetCurrentPattern(ValuePattern.Pattern)).Current.Value as string;
}
else
{
if (process == null)
throw new ArgumentNullException("process");
if (process.MainWindowHandle == IntPtr.Zero)
return null;
AutomationElement element = AutomationElement.FromHandle(process.MainWindowHandle);
if (element == null)
return null;
AutomationElement edit = element.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));
string result = ((ValuePattern)edit.GetCurrentPattern(ValuePattern.Pattern)).Current.Value as string;
return result;
}
}

You can not use this code for firefox too.
I recommend a third party library named NDde to do this very easily.
Here is NDde link
public string GetFirefoxUrl()
{
try
{
Process[] pname = Process.GetProcessesByName("Firefox");
if (pname.Length != 0)
{
DdeClient dde = new DdeClient("Firefox", "WWW_GetWindowInfo");
dde.Connect();
string url = dde.Request("URL", int.MaxValue);
url= url.Replace("\"", "").Replace("\0", "");
dde.Disconnect();
return url;
}
else
return null;
}
catch
{
return null;
}
}

Global service of the Team explorer's Query results window

What is the Query results window's global service (interface)? Code below:
var dteService = Package.GetGlobalService(typeof(EnvDTE.DTE)) as EnvDTE.DTE;
if (dteService == null)
{
Debug.WriteLine("");
return;
}
var something=Package.GetGlobalService(typeof(???)) as ???;
EDIT: The goal is, when I press the context menu button, I want the function callback to be able to access the service where the work item is selected (or the results list

Please check this case in MSDN forum for the details how to get it work: https://social.msdn.microsoft.com/Forums/vstudio/en-US/2d158b9c-dec1-4c59-82aa-f1f2312d770b/sdk-packageget-selected-item-from-query-results-list
The following code is quoted from above link for your quick reference:
Document activeDocument = _applicationObject.ActiveDocument;
if (activeDocument != null)
{
DocumentService globalService = (DocumentService)Package.GetGlobalService(typeof(DocumentService));
if (globalService != null)
{
string fullName = activeDocument.FullName;
IWorkItemTrackingDocument document2 = globalService.FindDocument(fullName, null);
if ((document2 != null) && (document2 is IResultsDocument))
{
int[] selectedItemIds = ((IResultsDocument)document2).SelectedItemIds;
}
}
}

var dteService = Package.GetGlobalService(typeof(EnvDTE.DTE)) as EnvDTE.DTE;
if (dteService == null)
{
Debug.WriteLine("");
return;
}
DocumentService documentService = Package.GetGlobalService(typeof(DocumentService)) as DocumentService;
if (documentService == null)
return;
string fullName = dteService.ActiveDocument.FullName;
IWorkItemTrackingDocument activeDocument = documentService.FindDocument(fullName, null);
if (activeDocument == null || !(activeDocument is IResultsDocument))
return;

Retrieve current URL from C# windows forms application

I have been designing a program using Visual C# and have came across an issue with making my program interact with web browsers. Basically what I need is to retrieve the URL address from a web browser (Internet Explorer, Firefox, Chrome etc...).
I figured this wouldn't be too difficult of a task, but after days and days of research and tests, it seems almost impossible! Thus far, I have come across this...
Get Firefox URL?
Which has the code below:
using NDde.Client;
Class Test
{
public static string GetFirefoxURL()
{
DdeClient dde = new DdeClient("Firefox", "WWW_GetWindowInfo");
dde.Connect();
string url = dde.Request("URL", int.MaxValue);
dde.Disconnect();
return url;
}
}
Which is perfect for Firefox, but for some reason I cannot get it to work with anything else. I have changed the portion of the code that says "Firefox" to "Iexplore" like I found all over the internet, along with trying other forms of expressing Internet Explorer, and I get the following error:
"Client failed to connect to "IExplorer|WWW_GetWindowInfo", Make sure the server application is running and that it supports the specified service name and topic name pair"
Any help on the issue would be much appreciated as it has become quite a task to figure out.

Here is a code based on Microsoft UI Automation:
public static string GetChromeUrl(Process process)
{
if (process == null)
throw new ArgumentNullException("process");
if (process.MainWindowHandle == IntPtr.Zero)
return null;
AutomationElement element = AutomationElement.FromHandle(process.MainWindowHandle);
if (element == null)
return null;
AutomationElement edit = element.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));
return ((ValuePattern)edit.GetCurrentPattern(ValuePattern.Pattern)).Current.Value as string;
}
public static string GetInternetExplorerUrl(Process process)
{
if (process == null)
throw new ArgumentNullException("process");
if (process.MainWindowHandle == IntPtr.Zero)
return null;
AutomationElement element = AutomationElement.FromHandle(process.MainWindowHandle);
if (element == null)
return null;
AutomationElement rebar = element.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ClassNameProperty, "ReBarWindow32"));
if (rebar == null)
return null;
AutomationElement edit = rebar.FindFirst(TreeScope.Subtree, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));
return ((ValuePattern)edit.GetCurrentPattern(ValuePattern.Pattern)).Current.Value as string;
}
public static string GetFirefoxUrl(Process process)
{
if (process == null)
throw new ArgumentNullException("process");
if (process.MainWindowHandle == IntPtr.Zero)
return null;
AutomationElement element = AutomationElement.FromHandle(process.MainWindowHandle);
if (element == null)
return null;
AutomationElement doc = element.FindFirst(TreeScope.Subtree, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document));
if (doc == null)
return null;
return ((ValuePattern)doc.GetCurrentPattern(ValuePattern.Pattern)).Current.Value as string;
}
You can use the UI Spy tool to understand the visual hierarchy for all 3 browsers. You may need to adapt things to make sure it really work in your specific cases, but you should get the general idea with these samples.
And an example that dumps all urls for all the 3 types of process (IE, FF, CH) currently running in the system:
static void Main(string[] args)
{
foreach (Process process in Process.GetProcessesByName("firefox"))
{
string url = GetFirefoxUrl(process);
if (url == null)
continue;
Console.WriteLine("FF Url for '" + process.MainWindowTitle + "' is " + url);
}
foreach (Process process in Process.GetProcessesByName("iexplore"))
{
string url = GetInternetExplorerUrl(process);
if (url == null)
continue;
Console.WriteLine("IE Url for '" + process.MainWindowTitle + "' is " + url);
}
foreach (Process process in Process.GetProcessesByName("chrome"))
{
string url = GetChromeUrl(process);
if (url == null)
continue;
Console.WriteLine("CH Url for '" + process.MainWindowTitle + "' is " + url);
}
}

Mourier, thank you for your solution Microsoft UI Automation.
Even so it didn't worked for Firefox 41.0,
I analysed the Firefox window structure with the little tool "Automation Spy".
Then I've changed the search conditions slightly, and it worked perfectly!
public static string GetFirefoxUrl(Process process)
{
if (process == null)
throw new ArgumentNullException("process");
if (process.MainWindowHandle == IntPtr.Zero)
return null;
AutomationElement element = AutomationElement.FromHandle(process.MainWindowHandle);
if (element == null)
return null;
element = element.FindFirst(TreeScope.Subtree,
new AndCondition(
new PropertyCondition(AutomationElement.NameProperty, "search or enter address", PropertyConditionFlags.IgnoreCase),
new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit)));
if (element == null)
return null;
return ((ValuePattern)element.GetCurrentPattern(ValuePattern.Pattern)).Current.Value as string;
}
And here is the solution for Chromium 48:
public static string GetChromeUrl(Process process)
{
if (process == null)
throw new ArgumentNullException("process");
if (process.MainWindowHandle == IntPtr.Zero)
return null;
AutomationElement element = AutomationElement.FromHandle(process.MainWindowHandle);
if (element == null)
return null;
AutomationElement edit = element.FindFirst(TreeScope.Subtree,
new AndCondition(
new PropertyCondition(AutomationElement.NameProperty, "address and search bar", PropertyConditionFlags.IgnoreCase),
new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit)));
return ((ValuePattern)edit.GetCurrentPattern(ValuePattern.Pattern)).Current.Value as string;
}
Automation Spy shows Firefox window controls structure. The control of type 'edit' with the name 'Search or enter address' holds the url:
Note: In your .NET project you need 2 references:
UIAutomationClient.dll
UIAutomationTypes.dll

Use parameter "1" instead of "URL" in oDde.Request("URL", int.MaxValue) for IE.
public static void ProcessIEURLs()
{
string sURL;
try
{
DdeClient oDde = new DdeClient("IExplore", "WWW_GetWindowInfo");
try
{
oDde.Connect();
sURL = oDde.Request("1", int.MaxValue);
oDde.Disconnect();
bool bVisited = false;
if ( oVisitedURLList != null && oVisitedURLList.Count > 0 )
{
bVisited = FindURL(sURL, oVisitedURLList);
}
if ( !bVisited )
{
oVisitedURLList.Add(sURL);
}
}
catch ( Exception ex )
{
throw ex;
}
}
catch ( Exception ex )

throw ex;

}

WWW_GetWindowInfo is supported in IE and has been since version 3.02 back in the 16 bit days! Works for Firefox and Opera
I believe that Chrome is in fact the odd one out.
I've got no knowledge of how things are beyond those four.
