Disable/remove child Breakpoints?

Question

I\'m debugging an ASP.NET Website with C# in Visual Studio. When I set a breakpoint (during debug), over time, the created breakpoint will accumulate many child breakpoints.

Answer 1

The following code can be used as a macro to remove all the child breakpoints.

Sub RemoveChildBreakpoints()
    Dim i As Integer
    Dim len As Integer
    Dim debugger As EnvDTE.Debugger = DTE.Debugger
    Dim children As EnvDTE.Breakpoints
    For Each bp As EnvDTE.Breakpoint In debugger.Breakpoints
        children = bp.Children
        len = children.Count
        For i = len To 1 Step -1
            children.Item(i).Delete()
        Next
    Next
End Sub

It's still insanely slow if you have many breakpoints, so it's best to do run it on a regular basis if you're having a problem with child breakpoints.

Here's an updated macro for the new javascript based macro add-in (https://marketplace.visualstudio.com/items?itemName=VisualStudioPlatformTeam.MacrosforVisualStudio) to remove all children breakpoints:

/// <reference path="C:\Users\ERobishaw\AppData\Local\Microsoft\VisualStudio\14.0\Macros\dte.js" />
try {

    var outputWindowPane = dte.Windows.Item("{34E76E81-EE4A-11D0-AE2E-00A0C90FFFC3}").Object.ActivePane;
    outputWindowPane.Activate();
    outputWindowPane.OutputString("display this text in the output window panel\n");

    var i;
    var len;
    var dbgr = dte.Debugger;
    var brk = dbgr.Breakpoints;
    outputWindowPane.OutputString("There are " + brk.Count + " Total\n");
    //Macro.InsertText("There are " + brk.Count + " Total");
    for (var bpi = 1; bpi <= brk.Count; bpi++) {
        outputWindowPane.OutputString("On " + bpi + " of " + brk.Count + "\n");
        var bp = brk.Item(bpi);
        var children = bp.Children;
        var len = children.Count;
        
        for (var chi = len; chi > 0; chi--) {
            outputWindowPane.OutputString(" Children Count = " + children.Count + "\n");
            children.Item(chi).Delete();
        }
    }
}
catch (e) {
    outputWindowPane.OutputString("Error\n");
    outputWindowPane.OutputString(e + "\n");
}

The following code can be used as a macro to remove the breakpoint on the currently selected line. (Note that Visual Studio automatically selects the line of a breakpoint when it is hit.)

Sub RemoveBreakPoint()
    Dim debugger As EnvDTE.Debugger = DTE.Debugger
    Dim children As EnvDTE.Breakpoints
    Dim sel As Integer = DTE.ActiveDocument.Selection.ActivePoint.Line
    For Each bp As EnvDTE.Breakpoint In debugger.Breakpoints
        If bp.File <> DTE.ActiveDocument.FullName Then
            Continue For
        End If
        For Each bpc As EnvDTE.Breakpoint In bp.Children
            If bpc.FileLine = sel Then
                bp.Delete()
                Exit For
            End If
        Next
    Next
End Sub

You can assign a keyboard shortcut to it for easy access. (Tools > Options > Environment > Keyboard.)
