Hotkeys for Previous and Next call stack frames in Visual Studio - visual-studio

Question

Visual Studio gives many navigation hotkeys:
F8 for next item in current panel (search results, errors ...),
Control+K, N for bookmarks,
Alt+- for going back and more.
There is one hotkey that I can't find, and I can't even find the menu-command for it, so I can't create the hotkey myself.
I don't know if such exist: Previous and Next call-stack frame.
I try not using the mouse when programming, but when I need to go back the stack, I must use it to double click the previous frame.
Anyone? How about a macro that does it?

Answer 1

I wrote 2 macros to gain it: PreviousStackFrame and NextStackFrame and assigned shortcuts to
Function StackFrameIndex(ByRef aFrames As EnvDTE.StackFrames, ByRef aFrame As EnvDTE.StackFrame) As Long
For StackFrameIndex = 1 To aFrames.Count
If aFrames.Item(StackFrameIndex) Is aFrame Then Exit Function
Next
StackFrameIndex = -1
End Function
Sub NavigateStack(ByVal aShift As Long)
If DTE.Debugger.CurrentProgram Is Nothing Then
DTE.StatusBar.Text = "No program is currently being debugged."
Exit Sub
End If
Dim ind As Long = StackFrameIndex(DTE.Debugger.CurrentThread.StackFrames, DTE.Debugger.CurrentStackFrame)
If ind = -1 Then
DTE.StatusBar.Text = "Stack navigation failed"
Exit Sub
End If
ind = ind + aShift
If ind <= 0 Or ind > DTE.Debugger.CurrentThread.StackFrames.Count Then
DTE.StatusBar.Text = "Stack frame index is out of range"
Exit Sub
End If
DTE.Debugger.CurrentStackFrame = DTE.Debugger.CurrentThread.StackFrames.Item(ind)
DTE.StatusBar.Text = "Stack frame index: " & ind & " of " & DTE.Debugger.CurrentThread.StackFrames.Count
End Sub
Sub PreviousStackFrame()
NavigateStack(1)
End Sub
Sub NextStackFrame()
NavigateStack(-1)
End Sub

I have solved this problem with AutoHotkey. I made this a few months ago.
Suppose you wanted to use Control+1 and Control+2 and that Control+Alt+C is bound to showing the Call Stack window:
^1::SendInput !^c{down}{enter}
^2::SendInput !^c{up}{enter}
It seems to work pretty well. If you aren't already using AutoHotkey to show Visual Studio who's boss, please give it a shot. Your question indicates that you would benefit greatly from it. It's a game changer. Good luck.

I don't think theres an explict next-frame / prev-frame key binding but heres what I do.
CTRL-ALT-C is already bound to "Debug.CallStack"
This will focus you in the Call Stack Tool Window
Once focused in the Callstack window... Up & Down arrows will move you through the call stack frames
I've then bound
CTRL-C, CTRL-S to "DebuggerContextMenus.CallStackWindow.SwitchToFrame"
and
CTRL-C, CTRL-C to "DebuggerContextMenus.CallStackWindow.SwitchToCode"
both of which will take you back into the code window at the particular frame.
Hope that helps.

Huge thanks to #Oleg Svechkarenko for his answer that gave me a starting point in crafting this solution. Since modern versions of Visual Studio no longer have official macro support, this should drop in for those who use the Visual Commander plugin, but probably can be easily adapted for any other macro extension.
Here is the code for the command, I created one for navigating up the call stack and one for navigating down with the same code except the parameter passed to MoveStackIndex(), then bound keyboard shortcuts to them:
using EnvDTE;
using EnvDTE80;
using System;
public class C : VisualCommanderExt.ICommand
{
enum MoveDirection
{
Up,
Down,
}
private bool IsValidFrame(StackFrame frame)
{
string language = frame.Language;
bool result = (language == "C#" ||
language == "C++" ||
language == "VB" ||
language == "Python");
return result;
}
private void MoveStackIndex(EnvDTE80.DTE2 DTE, MoveDirection direction)
{
StackFrame currentFrame = DTE.Debugger.CurrentStackFrame;
bool foundTarget = false;
bool pastCurrent = false;
StackFrame lastValid = null;
foreach (StackFrame frame in DTE.Debugger.CurrentThread.StackFrames)
{
bool isCurrent = frame == currentFrame;
if (direction == MoveDirection.Down)
{
if (isCurrent)
{
if (lastValid == null)
{
// No valid frames below this one
break;
}
else
{
DTE.Debugger.CurrentStackFrame = lastValid;
foundTarget = true;
break;
}
}
else
{
if (IsValidFrame(frame))
{
lastValid = frame;
}
}
}
if (direction == MoveDirection.Up && pastCurrent)
{
if (IsValidFrame(frame))
{
DTE.Debugger.CurrentStackFrame = frame;
foundTarget = true;
break;
}
}
if (isCurrent)
{
pastCurrent = true;
}
}
if (!foundTarget)
{
DTE.StatusBar.Text = "Failed to find valid stack frame in that direction.";
}
}
public void Run(EnvDTE80.DTE2 DTE, Microsoft.VisualStudio.Shell.Package package)
{
if (DTE.Debugger.CurrentProgram == null)
{
DTE.StatusBar.Text = "Debug session not active.";
}
else
{
// NOTE: Change param 2 to MoveDirection.Up for the up command
MoveStackIndex(DTE, MoveDirection.Down);
}
}
}

Look in Tools->Options->Environment->Keyboard. Enter "stack" or "frame" and related menus will appear. It seems that there's no next and previous call-stack frame.
