c# - Programmatically reset VisualStudio shortcuts

Question

There are two related questions about resetting VisualStudio keyboard scheme and importing VisualStudio settings. However, this doesn't seem to play nice all together.

I have two settings files containing shortcuts:

<!-- IntelliJ.vssettings -->   
<ShortcutsScheme>Visual C# 2005</ShortcutsScheme>
<UserShortcuts>
  <Shortcut Command="ReSharper.ReSharper_GotoNextHighlight" Scope="Global">F12</Shortcut>
</UserShortcuts>

<!-- ReSharper.vssettings -->   
<ShortcutsScheme>Visual C# 2005</ShortcutsScheme>
<UserShortcuts>
  <!-- Implicitly has F12 assigned to Edit.GoToDefinition -->
</UserShortcuts>

As you see ReSharper.vssettings doesn't really have the F12 shortcut assigned, since it is the default for VisualStudio. Importing that file, will not reapply the ShortcutsScheme, which is Visual Studio C# 2005 in both cases. This in turn results in the fact, that F12 keeps executing the GotoNextHighlight command. Same problem when just using the import dialog.

Using DTE as follows to reset the keyboard scheme also doesn't work:

var property = dte.Properties["Environment", "Keyboard"];
property.Item("SchemeName").Value = "(Default)";

Exporting the default settings doesn't work for the same reason. As shown here no shortcuts are exported.

Question therefore: How can I reset the VisualStudio keyboard scheme programmatically using DTE?

What I actually need is the command to trigger the Reset button in Options | Environment | Keyboard dialog.

Answer 1

You can remove specific key bindings as per: Visual Studio key bindings configuration file

Unfortunately I dont have both IntelliJ and ReSharper to test if it works. If it does it'd be nice to do this using DTE however this solution is beyond the scope of DTE and would be trivial using System.IO.File.

UPDATE:

Question: How can I reset the VisualStudio keyboard scheme programmatically using DTE? What I actually need is the command to trigger the Reset button in Options | Environment | Keyboard dialog.

Unfortunately you cannot do it (AFAIK) because resetting the Keyboard Shortcuts is beyond the scope of DTE.

If you setup a VS AddIn Project called "ResetKeyBoard" and put a break point on the Exec method you will see DTE doesnt catch any Visual Studio events firing when you're inside the Tools Options window, they simply aren't exposed through the DTE Object model:

public void Exec(string commandName, vsCommandExecOption executeOption, ref object varIn, ref object varOut, ref bool handled)

This can also be demonstrated by Recording a Macro, the recorded commands only go so deep as to open the Option Dialog (no matter what settings you change inside):

Public Module RecordingModule
    Sub TemporaryMacro()
        DTE.ExecuteCommand("Tools.Options")
    End Sub
End Module

I did learn how to open the Keyboard tab of the Options window directly but since its a Modal Dialog you cant even use SendKeys to press the Reset button:

public void Exec(string commandName, vsCommandExecOption executeOption, ref object varIn, ref object varOut, ref bool handled)
        {
            handled = false;
            if(executeOption == vsCommandExecOption.vsCommandExecOptionDoDefault)
            {
                if(commandName == "ResetKeyBoard.Connect.ResetKeyBoard")
                {
                    _applicationObject.ExecuteCommand("Tools.Options", "BAFF6A1A-0CF2-11D1-8C8D-0000F87570EE");
                    System.Windows.Forms.SendKeys.Send("%e");
                    System.Windows.Forms.SendKeys.Send("{ENTER}");

The last DTE option I tried (without luck) is using Commands.Raise, again you cant get deeper than opening Tools Options or at least if you can its undocumented.

public void Exec(string commandName, vsCommandExecOption executeOption, ref object varIn, ref object varOut, ref bool handled)
{
    handled = false;
    if(executeOption == vsCommandExecOption.vsCommandExecOptionDoDefault)
    {
        if(commandName == "ResetKeyBoard.Connect.ResetKeyBoard")
        {
            Commands cmds = _applicationObject.Commands;
            Command cmdobj = cmds.Item("Tools.Options");
            object customIn = null;
            object customOut = null;
            _applicationObject.Commands.Raise(cmdobj.Guid, cmdobj.ID, ref customIn, ref customOut);

Workarounds:

a) I dont encourage you to replace the Visual C# 2005.vsk file, but if you want to investigate its this file:

C:Program Files (x86)Microsoft Visual Studio 1X.0Common7IDEVisual C# 2005.vsk

MSDN Warning

You cannot programmatically change the settings for the default keyboard mapping scheme. To change the settings, save a copy of the default keyboard mapping scheme in the Keyboard node in the Options dialog box. You can then change the settings in that mapping scheme.

I do not recommend or encourage this method, its bad programming and you could destroy someone's keyboard shortcuts!

b) Another way could be by creating your own VSK file and setting it in the currentSettings.vssettings:

    </ScopeDefinitions>
     <ShortcutsScheme>Visual C# JT</ShortcutsScheme>
    </KeyboardShortcuts>

Make sure you backup the currentSettings.vssettings file before changing it.

c) This leads back to Chris Dunaway's suggestion where you create a vssettings file (purely containing keyboard shortcuts) and import that in to reset the keyboard shortcuts. I realise the default shortcuts are not saved, however here is some code you can use with DTE to export the commands out, to insert into a new vssettings file to then import in:

//note, this is untested code!
public void Exec(string commandName, vsCommandExecOption executeOption, ref object varIn, ref object varOut, ref bool handled)
{
    handled = false;
    if(executeOption == vsCommandExecOption.vsCommandExecOptionDoDefault)
    {
        if(commandName == "ResetKeyBoard.Connect.ResetKeyBoard")
        {
            System.Diagnostics.Debug.WriteLine("<UserShortcuts>");
            foreach (Command c in _applicationObject.Commands)
            {
                if (!string.IsNullOrEmpty(c.Name))
                {
                    System.Array bindings = default(System.Array);
                    bindings = (System.Array)c.Bindings;
                    for (int i = 0; i <= bindings.Length - 1; i++)
                    {
                        string scope = string.Empty;
                        string keyShortCut = string.Empty;
                        string[] binding = bindings.GetValue(i).ToString().Split(new string[] {  "::" },StringSplitOptions.RemoveEmptyEntries );
                        scope = binding[0];
                        keyShortCut = binding[1];
                        System.Diagnostics.Debug.WriteLine("<RemoveShortcut Command="..." Scope="" + scope + "">" + keyShortCut + "</RemoveShortcut>");
                        System.Diagnostics.Debug.WriteLine("<Shortcut Command="" + c.Name + "" Scope="" + scope + "">" + keyShortCut + "</Shortcut>");
                    }
                }
            }
            System.Diagnostics.Debug.WriteLine("</UserShortcuts>");

Once you've got them out its easy to import them in:

_applicationObject.ExecuteCommand("Tools.ImportandExportSettings", "/import:"KeyboardOnly-Exported-2016-08-29.vssettings"");
