New WintellectPowerShell Version with Visual Studio 2017 Support

John Robbins

18 Jan , 2017  

We have a new version of Visual Studio coming soon so I did the work to update my WintellectPowerShell module to support it. And, what a huge adventure that turned out to be! I will discuss why its support for Visual Studio 2017 was hard a bit later in this blog entry. For those of you who are new to WintellectPowerShell, it is a module that brings a number of useful cmdlets for setting up symbol and source servers for Visual Studio 2013-2017 as well as WinDBG. Other cmdlets automatically download and extract all the lovely goodness of the SysInternal tools, automate the analysis of lots of minidump files, and so on. The module has been helpful to me over the years. You can look at all the source code on GitHub: https://github.com/Wintellect/WintellectPowerShell. To install WintellectPowerShell directly, execute the following command in PowerShell:

  1. Install-Module -Name WintellectPowerShell -Scope CurrentUser

If you have a previous version of WintellectPowerShell installed, you will see an ‘Authenticode issuer’ error when you try to update. The error is because since I last released a WintellectPowerShell build, my code signing certificate needed to be renewed. When PowerShellGet does checks a signed module, it checks all the certificate fields.… Read more

Get Function Keys By Default with Parallels and a MacBook Pro Touch Bar

John Robbins

27 Dec , 2016  

Having purchased a 15 inch MacBook Pro with Touch Bar recently, I’ve been having a good time seeing how that Touch Bar can be used. With applications that know about the Touch Bar, it is an interesting UI approach. But with many macOS applications not having full Touch Bar support, I’ll reserve full judgment until most apps support it. I will say that the Photos app shows a tremendously useful way to use the Touch Bar.

One app I use all the time, the virtual machine program Parallels, does not currently support the Touch Bar, so whenever you are in it, you see the default Touch Bar view:

The only problem is that for Windows development, you really, really need those function keys. Sure you can press the FN key to have them come back, but I wanted the function keys to be the default. A little poking around in System Preferences, Keyboard settings, Shortcuts, showed the Function Keys section. I added Parallels Desktop to the list and, voila, now Parallels defaults to showing the function keys whenever Parallels has focus. Not the most earth shattering of tips, but one that certainly made my life better.

Now if only Apple would sell a Touch Bar external keyboard…… Read more

Learn Faster, More Effective Debugging With This Webinar

John Robbins

10 Nov , 2016   Video

When a developer says they are debugging their code, that really means they are doing some superficial looking in the debugger. Today’s debuggers are so much more powerful than most developers realize. With a little bit of training they can easily cut the time they spend debugging by 20 percent. That means more time spent on features that customers want, which means more revenue for the company. Even more important is learning how to deal with problems that occur in production. Very few developers know anything about the real tools used to quickly solve those production problems.

If you would like to learn more about debugging using Visual Studio and its amazing breakpoint capabilities, make sure to attend this free one-hour webinar, ‘Taking a Break in the Debugger,’ led by John Robbins, the head of Wintellect’s Debugging Service and a prolific author/speaker on all things related to debugging. Click on the video above to view, and let us know your feedback in the comments.… Read more

FastFileFinder Now 30 Percent Faster—How Fast Can You Make It?

John Robbins

21 Feb , 2016  

A while ago I whipped up a small utility to search for filenames at the command line. I noticed recently that it did not handle long filenames over 260 (MAX_PATH) characters. Having a few spare minutes I updated FastFileFinder to use the Win32 API directly as the .NET Framework Directory methods do not have that support. Additionally, I took at idea from Josh Carroll and batched up the matching filename output to minimize the calls to Console.WriteLine.

With that little bit of work FastFileFinder is now 30%-50% faster! I haven’t looked too much harder but I think there’s some more speed up work that can be done. Are you up for the challenge? How much faster can you make it go?

WintellectPowerShell Now on the PowerShell Gallery

John Robbins

7 Nov , 2015  

Getting and installing modules is easier than ever with the PowerShell Gallery and PowerShellGet. Instead of downloading and extracting files into your PowerShell modules directory, a simple call to Install-Module takes care of everything for you. Today I’ve published my WintellectPowerShell module. Now you can install and get started setting up Visual Studio to access symbol server, source servers, and many other cmdlets for debugging support. All you need to do with PowerShell 5.0 (or by adding the Package Management Preview to PowerShell versions 3 or 4) is issue the following command:

  1. Install-Module -Name WintellectPowerShell -Scope CurrentUser

 

If you haven’t heard of WintellectPowerShell, here are all the commands it offers.

TOPIC
about_WintellectPowerShell

SHORT DESCRIPTION
Provides cmdlets for setting up symbol servers and other
functionality related to debugging and performance tuning.

LONG DESCRIPTION
This module makes setting up symbol servers and source server debugging
functionality easier to control for Visual Studio 2010 through 2015
and WinDBG. Setting up a development machine for symbol server
access is more difficult than it needs to be but no more.

You can have any combination of Visual Studio 2010 through 2015, and
WinDBG on the computer for these cmdlets to work.

These cmdlets had been originally developed as PowerShell scripts by John
Robbins and released on his blog.

Fixing MacBook Pro Windows 10 In Place Upgrade Issues

John Robbins

2 Aug , 2015  

On my production machine, my Apple MacBook Pro, I did an in place upgrade from Windows 8.1 to Windows 10. I ran into a couple of bumps and got them figured out so I thought I’d post this for others seeing the same problems. That way when combined with the power of Greyskull (AKA internet search engines) they can get answers if they hit the same issues.

The first issue I ran into had nothing to do with the MacBook Pro. I’d been short on disk space so pushed my 7 GB C:\Windows\Installer\$PatchCache$ directory to another drive with a directory link. That worked fine in Windows 8.1, but about 40% through the pre boot processing in Windows 10 setup I’d get the awesome “Something Happened” error. I’d made a strong mental note that I’d moved the $PatchCatch$ directory so that was the first thing I fixed. I had to make some room on the drive so did things like deleting my Outlook .OST file, which would get recreated the next time I started Outlook.

With 9 GB free on my C: drive, and $PatchCache$ in the proper location, I tried again. The upgrade was smooth sailing at that point. Once I logged into Windows 10, and deleted Windows.Old through the Disk Cleanup Utility, I was thrilled to see my 8 GB fee space had jumped to 19.2 GB.… Read more

Turn off the Attach Security Warning Dialog in Visual Studio

John Robbins

10 Jul , 2015  

How many clicks has this dialog eaten out of your life?

AttachWarning

The idea for the warning is good because, you know, SECURITY. However, if you’re developing web apps or anything running in IIS, this gets old by the thousandth time you click the Attach button. It’s easy to turn off with an undocumented registry key. Make sure to shut down all instances of VS before changing this key as it will get overwritten on shutdown.

For Visual Studio 2015: HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0\Debugger
For Visual Studio 2013: HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0\Debugger

In the Debugger key, add a REG_DWORD value of DisableAttachSecurityWarning and set it to 1, and you now have one less click when you attach to a process.… Read more

Automating Analyzing Tons of Minidump Files with WinDBG and PowerShell

John Robbins

5 May , 2015  

When debugging a nasty problem in your code, one of the most helpful things you can get is a minidump. With that picture of what your app was doing at the time of the crash, hang, or when the memory started spiking, you’ve got a big hint to jumpstart your exploring. While there’s a bunch of tools out there, such as the wonderful ProcDump, and the debuggers themselves to create minidumps, the real moment of truth is when you have to look at those minidump. That’s easy to do with one or two, but what happens if you have 200? In my line of work, where I debug other’s software problems (and will be glad to help you with yours), I’m routinely faced with hundreds of dumps from a client. As much as I would like to carefully open each minidump and lovingly type the same commands over and over for the greatest consulting billing statement ever, I just can’t get my clients to pay for that.

What I really need is a way to say, “Here’s a bunch of .DMP files; go run these WinDBG commands across all of them.” It turns out that accomplishing that basic task is not hard at all when you combine a little WinDBG knowledge with a little PowerShell magic.… Read more

Wintellect.Analyzers for VS 2015 RC and Fixing Analyzer Install Problems with the Default Template Projects

John Robbins

4 May , 2015  

Now that Visual Studio 2015 RC is fresh off the build machines and available for everyone, I’ve updated my Wintellect.Analyzers project (http://johnr.us/1bEO4h8) with full RC support. Go forth and add them to your project so you can get the benefit of advanced compiler analysis and code fixes. To add the analyzers, hit up your Package Manager Console with the following command:

  1. Install-Package Wintellect.Analyzers Prerelease

I guess you could go through the fancy new NuGet window in Visual Studio, but you want to be hard core and use PowerShell in VS!

If you’re interested in writing your own analyzers, as I have discussed previously, you’re immediately going to run into errors and warnings with projects based off the default Roslyn template when you try to install your analyzer masterpiece. Here’s what you’ll see:

Attempting to gather dependencies information for package ‘Analyzer1.1.0.0’ with respect to project targeting ‘.NETPortable, Version=v4.5, Profile=Profile7’
Attempting to resolve dependencies for package ‘Analyzer1.1.0.0’ with DependencyBehavior ‘Lowest’
Resolving actions to install package ‘Analyzer1.1.0.0’
Resolved actions to install package ‘Analyzer1.1.0.0’
Adding package ‘Analyzer1 1.0.0.0’ to folder ‘c:\junk\code\Analyzer1\packages’
Added package ‘Analyzer1 1.0.0.0’ to folder ‘c:\junk\code\Analyzer1\packages’

Free 1.5 Hour Video: Writing Roslyn Analyzers and Code Fixes

John Robbins

7 Apr , 2015  

My deep abiding love of Roslyn continues! I just published a new video Writing Roslyn Analyzers and Code Fixes up at WintellectNOW: https://www.wintellectnow.com/Videos/Watch?videoId=writing-roslyn-analyzers-and-code-fixes. My goal was to take you from zero knowledge of Roslyn to writing a real world analyzer and code fix in 1.5 hours. This video covers everything from using the Syntax Visualizer to developing and testing analyzers and code fixes. Along the way I show how I solved some of the hard real world issues you’ll encounter.

Given that there’s not a lot of documentation on Roslyn I thought this video would help get folks up to speed as we approach the release date for Visual Studio 2015. I would love to hear any and all constructive criticisms you have on the video. What did I do right, what did I do wrong, and what else do you want to see. Sign up for a free WintellectNOW account and post to the discussion area under the video.

Please note that we reserve the right to move the video to subscription required in the future. Given how new Roslyn and VS 2015 are at the time of recording we thought it was good to get the info out now.Read more
