Welcome to Stephen's wiki. There is lots of really great content here - you just have to search for it.

This is a collection of random stuff I want to record for future reference. Probably not much use to anyone else.

Trace = 0, Debug = 1, Information = 2, Warning = 3, Error = 4, Critical = 5, and None = 6.

Rubix and I did approximately 1,547 runs and covered 16,347kms together. First run was 2015-08-24, last was around 2024-07-24.

Hold down the ☀️ button for ages. Watch will power off. Press it again to power on. Settings etc. are not lost.

Create a something.runsettings file and put it in the solution directory:

<?xml version="1.0" encoding="utf-8"?>
<!-- File name extension must be .runsettings -->
<RunSettings>
	<RunConfiguration>
		<EnvironmentVariables>
			<!-- List of environment variables we want to set-->
			<ENABLE_GOD_MODE>true</ENABLE_GOD_MODE>
		</EnvironmentVariables>
	</RunConfiguration>
</RunSettings>

Getting Visual Studio to use the file is a bit tricky. Try Test → Configure Test Settings. You may need the 'Select Solution Wide runsettings File'. Eventually the file itself should appear in the menu.

To test, debug and stop at a breakpoint. Run Environment.GetEnvironmentVariables() in the Immediate Window.

This will only work inside an ASP.NET project.

using System.Web.Mvc;
 
private ILog _log;
private ILog Log => _log ?? (_log = (ILog)DependencyResolver.Current.GetService(typeof(ILog)));

Running this worked on my Azure Dev VM:

ForEach-Object { Invoke-Expression "$env:windir\system32\cscript.exe $env:windir\system32\slmgr.vbs /ato" ; start-sleep 5 }

Could not find a part of the path 'C:\Dev\BucketsOfFunds\BucketsOfFunds.Web\bin\roslyn\csc.exe'.

Run this in the Package Manager Console:

Update-Package Microsoft.CodeDom.Providers.DotNetCompilerPlatform -r

notepad $PROFILE

Add this to the top:

[system.net.webrequest]::defaultwebproxy = new-object system.net.webproxy('http://10.104.66.70:80')
 
# To use your current Windows account to log on to the proxy:
[system.net.webrequest]::defaultwebproxy.credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials
 
# To use a different Windows account:
$Username="domain\username"
$Password="password"
[system.net.webrequest]::defaultwebproxy.credentials = New-Object System.Net.NetworkCredential($Username, $Password)
 
[system.net.webrequest]::defaultwebproxy.BypassProxyOnLocal = $true

Restart your PowerShell session. Fix up the repository source:

Register-PSRepository -Default

Check you have a repository:

Get-PSRepository

Should get https://www.powershellgallery.com/api/v2.

1. Open MMC.
2. Add the Certificates snap-in for 'Computer account'.
3. Console Root > Certificates (Local Computer) > Personal > Certificates.
4. localhost (IIS Express Development Certificate) > Right click > Copy.

(Get-WmiObject Win32_Process -Filter "name = 'Chrome.exe'" | Where-Object { $_.CommandLine.Contains("--enable-automation") }).Terminate()

And if you want to get rid of the Chrome driver as well (which is always a good idea):

(Get-WmiObject Win32_Process -Filter "name = 'Chrome.exe'" | Where-Object { $_.CommandLine.Contains("--enable-automation") }).Terminate(); (Get-WmiObject Win32_Process -Filter "name = 'chromedriver.exe'").Terminate();

using (ShimsContext.Create())
{
	System.Fakes.ShimDateTime.NowGet = () => new DateTime(2019, 03, 31);
	...
}

Copy and paste the below into the filter.

-is:running -status-code:200 -status-code:302 -status-code:204 -status-code:304 -status-code:307

Requires the Moq NuGet package.

[TestMethod]
public void MealViewModel_Banana_EatMethodIsCalled_DrinkIsNot()
{
	IUtensil spoon = new Spoon();
	var mockBanana = new Mock<BananaViewModel>();
	var test = new MealViewModel();
	testMeal.Banana = mockBanana.Object;
 
	// Calling Eat() on the meal should also call Eat() on the banana.
	testMeal.Eat(spoon);
 
	mockBanana.Verify(banana => banana.Eat  (It.IsAny<IUtensil>()), Times.Once,  "Banana should be eaten with a utensil.");
	mockBanana.Verify(banana => banana.Drink(It.IsAny<IUtensil>()), Times.Never, "Banana should not be drunk.");
	// Not sure if an interface will work here -------^^^^^^^^
}

Fix it thusly:

1. Close Visual Studio.
2. Delete everything in %LocalAppData%\Microsoft\VisualStudio\14.0\ComponentModelCache
3. Open Visual Studio.

Get-ChildItem *.mp3 | ForEach-Object{Rename-Item $_ -NewName "$(Get-Random) $($_.Name).mp3"}

Run this and find out:

powercfg -lastwake

Add the 'AntiXSS' (Microsoft) package from NuGet.

Chris used an abstract base class. The following should be adapted for an interface, if possible.

/*
  <appSettings>
    <add key="definitionService" value="EA.ReportingPortal.Services.DbDefinitionService" />
  </appSettings>
*/ 
public abstract class DefinitionService
{
	public abstract List<CategoryTag> GetAllCategories();
	// ...
 
	public static DefinitionService Current
	{
		get
		{
			var activeServiceName = WebConfigurationManager.AppSettings["DefinitionService"];
			if (string.IsNullOrWhiteSpace(activeServiceName))
				throw new ConfigurationErrorsException("Definition Service type not specified or blank");
 
			var serviceType = typeof(DefinitionService).Assembly.GetType(activeServiceName);
			if (serviceType == null || !typeof(DefinitionService).IsAssignableFrom(serviceType))
				throw new ConfigurationErrorsException("Definition Service type does not exist or does not inherit from DefinitionService");
 
			var defaultConstructor = serviceType.GetConstructor(Type.EmptyTypes);
			if (defaultConstructor == null)
				throw new ConfigurationErrorsException("Definition Service type does not have an empty constructor");
 
			return (DefinitionService)defaultConstructor.Invoke(null);
		}
	}
}

((System.Data.Objects.ObjectQuery)myQuery).ToTraceString()

Or, if you want an extension method:

public static class IQueryableExtensions
{
    public static string ToTraceString<T>(this IQueryable<T> t)
    {
        ObjectQuery<T> oqt = t as ObjectQuery<T>;
 
        return oqt == null ? string.Empty : oqt.ToTraceString();
    }
}

Visual Studio can sometimes get a bit confused about which TFS workspaces exist and which don't. Sort it out with the Visual Studio Command Prompt.

Figure out what workspaces really exist:

tf workspaces /collection:sourcecontrol.company.co.nz\DefaultCollection

Well and truly delete the motherfucker:

tf workspace /delete workspacename

If tf starts complaining about “Unable to determine the source control server”, try running the first command again (it seems to magically fix shit up or something):

tf workspaces /collection:sourcecontrol.company.co.nz\DefaultCollection

¹ Simple, Moderate, Advanced, Enterprise
² Gave up googling, api changes often, lots of out-of-date info on web.

<div @(item.Selected ? string.Empty : "style=display:none")></div>

Note that Razor is quite fussy about the format of the style=display:none bit. No spaces.

A less nice method that also works is:

<div class="notch" @(Html.Raw(item.Selected ? string.Empty : "style=\"display: none;\""))></div>

See ASP.NET MVC Security Check List.

On Windows 7 and above:

1. Start button.
2. Type Steps or PSR.
3. Click 'Record steps to reproduce a problem'.
4. Be amazed.

1. Download NuGet.Tools.vsix (look for it at nuget.org)
2. Uninstall NuGet from within Visual Studio.
3. Close Visual Studio.
4. Run the NuGet.Tools.vsix file to install the new version.

Search the application event log on the local machine:

LogParser.exe -i:evt -rtp:-1 "SELECT TOP 100 * FROM Application WHERE SourceName like '%Reporting%'" > d:\Temp\Output.txt 

Search the standard three event logs on the local machine:

LogParser.exe -i:evt -rtp:-1 "SELECT TOP 100 * FROM System, Application, Security WHERE SourceName like '%Reporting%'" > d:\Temp\Output.txt 

Search the application event log on a remote machine (may take a while):

LogParser.exe -i:evt -rtp:-1  "SELECT TOP 100 * FROM \\MachineName\Application WHERE SourceName like '%Reporting%'" > d:\Temp\Output.txt 

The -rtp:-1 option suppresses the “Press a key…” prompt.

In a Powershell console:

Get-Item *.jpg | ForEach-Object { magick convert $_ "$($_.basename).png" }

This also works:

Get-ChildItem 'C:\External Drives\Primary Media 2\My Pictures\Fractals\FA (Dual Monitor Wallpaper)' | Foreach { magick convert $_.FullName -resize 3840x1080! -quality 99 $_.Name }

For canvas prints through pixelpaint.co.nz, use 8E series images and convert to JPEG, < 15MB. Copy images from C:\External Drives\Primary Media 2\My Pictures\Fractals\8E (Printing) to a temp directory. Run this:

Get-ChildItem | Foreach { magick convert $_.FullName -quality 98 "$($_.basename).jpg" }

For any that are still bigger than 15MB, decrease quality and / or size (-resize 80%%).

1. Open Firefox and type about:config in the address bar.
2. In the Filter field enter network.automatic-ntlm-auth.trusted-uris.
3. Set the value to a comma separated list of sites:

   http://intranet.company.com,http://email.company.lan

How do I fix the following error:

‘dropdownlist1′ has a SelectedValue which is invalid because it does not exist in the list of items

1. Remove the SelectValue binding in the drop down:

   SelectedValue='<%# Bind("LocationId") %>'

2. In the code behind, add the following to the PreRender of the FormView:

   Protected Sub EmployeeDetailsFormView_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles EmployeeDetailsFormView.PreRender
   	If EmployeeDetailsFormView.CurrentMode = FormViewMode.Edit Then
   		Dim Location_DropDownList As DropDownList = CType(EmployeeDetailsFormView.FindControl("Location_DropDownList"), DropDownList)
    
   		Dim rowView As DataRowView = CType(EmployeeDetailsFormView.DataItem, DataRowView)
   		If IsNothing(rowView) Then Return ' Or perhaps throw an exception.
    
   		Dim locationId As String = rowView("LocationId").ToString() 
    
   		If Not IsNothing(Location_DropDownList.Items.FindByValue(locationId)) Then
   			Location_DropDownList.SelectedValue = locationId
   		Else
   			' TODO: Set the value to whatever it should be if there is no match.
   			Location_DropDownList.SelectedValue = "0"
   		End If
   	End If
   End Sub

3. Then add the following the ItemUpdating of the FormView:

   Protected Sub EmployeeDetailsFormView_ItemUpdating(ByVal sender As Object, ByVal e As FormViewUpdateEventArgs) Handles EmployeeDetailsFormView.ItemUpdating
   	Dim Location_DropDownList As DropDownList = CType(EmployeeDetailsFormView.FindControl("Location_DropDownList"), DropDownList)
    
   	e.NewValues("LocationId") = Location_DropDownList.SelectedValue
   End Sub

1. Open the Excel file in a Hex Editor (XVI32 will do nicely).

   4. Save the project.
4. Run the unit tests.
5. Turn the Code Coverage Colouring on and off in the Code Coverage Results window.

…and maintaining version history.

1. [SubVersion] Export the trunk to a temp directory.
   • C:\Temp\SuperApp\trunk
2. [Text Editor] In the temp solution, open the solution file.
   • C:\Temp\SuperApp\trunk\SuperApp.sln
3. [Text Editor] Find the section that has Web Site Project. It will look something like:

   Project("{E24C65DC-7377-472B-9ABA-BC803B73C61A}") = "SuperApp.Web", "SuperApp.Web", "{C92B633A-C441-4FB6-904B-EEA604BAAF15}"
   	ProjectSection(WebsiteProperties) = preProject
   		...
   		ProjectReferences = "{0A231AD6-AF0C-45C1-B441-2AB97BC40975}|SuperApp.DataAccess.dll;{96DC8217-C24D-4851-B4C2-92FBE60727CC}|SuperApp.Business.dll;"
   		...
   	EndProjectSection
   EndProject

4. [Text Editor] Note down any project references for later. In the example above, the Web Site Project references SuperApp.DataAccess.dll and SuperApp.Business.dll.
5. [Text Editor] Delete the entire Web Site Project (from Project to EndProject inclusive) and save.
6. [Windows Explorer] In the temp solution, delete the entire Web Site Project directory
   • C:\Temp\SuperApp\trunk\SuperApp.Web
7. [Visual Studio] Open the temp solution.
8. [Visual Studio] Create a new ASP.NET Empty Web Application in the old Web Site Project directory. Make sure it is the correct language (VB or C#)! The language of new ASP.NET Empty Web Application must match the existing Web Site Project.
   • C:\Temp\SuperApp\trunk\SuperApp.Web
9. [Visual Studio] Save and close.
10. [SubVersion] Copy and rename to a branch.
    • C:\Dev\SuperApp\trunk → C:\Dev\SuperApp\branches\Converting to Web App
11. [Text Editor] In the branch solution, open the solution file.
    • C:\Temp\SuperApp\branches\Converting to Web App\SuperApp.sln
12. [Text Editor] Remove the Web Site Project and save.
13. [Windows Explorer] Copy from the temp solution to the branch solution:
    • (C#) C:\Temp\SuperApp\trunk\SuperApp.Web\Properties → C:\Temp\SuperApp\branches\Converting to Web App\SuperApp.Web
    • (VB) C:\Temp\SuperApp\trunk\SuperApp.Web\My Project → C:\Temp\SuperApp\branches\Converting to Web App\SuperApp.Web
    • C:\Temp\SuperApp\trunk\SuperApp.Web\SuperApp.Web.csproj → C:\Temp\SuperApp\branches\Converting to Web App\SuperApp.Web
    • C:\Temp\SuperApp\trunk\SuperApp.Web\Web.Debug.config → C:\Temp\SuperApp\branches\Converting to Web App\SuperApp.Web
    • C:\Temp\SuperApp\trunk\SuperApp.Web\Web.Release.config → C:\Temp\SuperApp\branches\Converting to Web App\SuperApp.Web
14. [Text Editor] The Web.config in the branch solution probably does not need to be changed, but open both and check just in case.
    • C:\Dev\SuperApp\branches\Converting to Web App\SuperApp.Web\Web.config
    • C:\Temp\SuperApp\trunk\SuperApp.Web\Web.config
15. [Visual Studio] Open the branch solution.
16. [Visual Studio] In the Solution Explorer, turn on Show All files.
17. [Visual Studio] In the Web App project, include all the file and directories except the Bin and Obj directories.
18. [Visual Studio] Right click the Web App project and select Manage NuGet Packages.
19. [Visual Studio, Manage NuGet Packages dialog] If there is a message about restoring NuGet packages, do it.
20. [Visual Studio] Add the project references noted down in step 4.
21. [Visual Studio] Right click each ASPX file and select Convert To Web Application.
22. [Visual Studio] Set the Web App project as the start up project, and set the appropriate start page.
23. [Visual Studio] Cross fingers and run it.

ASP.NET's UpdatePanel will not work if xhtmlConformance mode is set to Legacy in the Web.config file:

<xhtmlConformance mode="Legacy" />

Take it out of the Web.config file - it almost certainly does not need to be in there.

With administrator privileges, edit the C:\Program Files (x86)\VideoLAN\VLC\lua\http\.hosts file, and set it to:

::/0
0.0.0.0/0

This will probably need to be done every time a new version of VLC is installed.

Probably caused by the Web.config file. Remove the following, if they exist:

<section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication"/>

Removing these from the Web.config doesn't seem to matter, but if it does, try adding the relevant DLL files and see if that fixes the problem.
