Download Tip: Create Regular Expressions in a snap

I have almost no clue about Regular Expressions, but still I can create even pretty complex RegEx patterns in a snap and therefore can impress collegues with those (almost non-existant) skills.

How do I do that, you will ask?

Well, I use Expresso Regular Expression Tool

It's free (although you have to register after a period to receive your free registration code) and helped me a lot. Highly Recommended!

SOLVED: The provided URI scheme 'http' is invalid; expected 'https'. Parameter name: via

You receive the error message:

The provided URI scheme 'http' is invalid; expected 'https'.
Parameter name: via

… while using WCF to connect to an endpoint.

Probably you are trying to send a a username and password to authenticate although the connection is not secure (no HTTPS).

This modified binding should help:

<binding name="UserPasswordBinding">
security mode="TransportCredentialOnly">
transport clientCredentialType="Basic" />

.NET Framework 4 Client Profile available through Windows Update

Beginning June 22, 2010 the .NET Framework 4 is available through WIndows Update to ease deployment.

The whole framework? No, only the "light" version, so called "Client Profile", which contains the features to develop a client application, including:

Common language runtime (CLR)

ClickOnce

Windows Forms

Windows Presentation Foundation (WPF)

Windows Communication Foundation (WCF)

Entity Framework

Windows Workflow Foundation

Speech

XSLT support

LINQ to SQL

Runtime design libraries for Entity Framework and WCF Data Services

Managed Extensibility Framework (MEF)

Dynamic types

Parallel-programming features, such as Task Parallel Library (TPL), Parallel LINQ (PLINQ), and Coordination Data Structures (CDS)

Debugging client applications

It does not include (meaning you still need to install the full .NET Framework 4.0 to use those features), for example:

ASP.NET

Advanced Windows Communication Foundation (WCF) functionality

.NET Framework Data Provider for Oracle

MSBuild for compiling

Now, it's on Windows update, will it install automatically?

It depends on the Windows Update settings, "the .NET Framework 4 Client Profile is released as a recommended update that may be installed automatically on Windows Vista and Windows 7. The Client Profile is released as an optional update for Windows XP. In Windows XP, you must manually run WU and select the .NET Framework 4 Client Profile".

.NET Framework 4 Client Profile:

• Recommended Update on Windows Vista/7
• Optional Update on Windows XP

Full .NET Framework 4:

• Optional Update on Windows Server 2003, Windows Server 2008 and on Windows Server 2008 R2

More Information?

• Description of Windows Update – Update Levels
• MIcrosoft Knowledge Base: The .NET Framework 4 Client Profile is available on Windows Update (KB 982670)

When using Remote Desktop the keyboard layout always defaults to EN (English)

You…

• use a different keyboard layout than EN (English)
• use Remote Desktop to connect to another machine
• the default keyboard/input language is set to EN (regardless of your user settings)

… then this is your solution:

On the machine you connect to run the following .REG file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"IgnoreRemoteKeyboardLayout"=dword:00000001

Download: IgnoreRemoteKeyboardLayout.zip

Solution: Internet Explorer detected as mobile device

Problem description:

"Internet Explorer redirects to mobile layout web site"
"Some websites are connecting to mobile version"
Why am I getting mobile sites? I'm using my desktop PC!

Solution: (as found in this thread)

1. In the Windows registry navigate to the following key:
   HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent\Post Platform
2. Remove the entry "Creative AutoUpdate v1.40.01"
3. Close all Internet Explorer windows.

Background:
Some websites are scanning the user agent string for the word "PDA", unfortunately the word "Update", contains PDA. Thus, those websites present their mobile versions instead.

SMTH-AUTH errors with System.Net.Mail

If you are getting SMTH AUTH errors while trying to send e-mails using the SmtpClient to an smtp server that requires authentication, make sure that you call UseDefaultCredentials before settings the credentials.

So, order is important here!

using System.Net;
using System.Net.Mail;
...
using (var client = new SmtpClient())
{
  client.Host = "smtp.teamfoundationserver.de";
  client.Port = 25;
  client.UseDefaultCredentials = false;
  client.Credentials = new NetworkCredential(username, password);
  client.Send(message);
}

Good luck!

Code Contracts: don't forget to turn them on

If you use the new System.Diagnostics.Contracts classes like

int Div(int a, int b)
{
  Contract.Requires(b > 0);
  return a / b;
}

Do not forget to download the Code Contracts tool and turn on static and/or runtime checking of your code.

Otherwise the Contract.Requires statement above will just be ignored (thus the second parameter will not be checked)…

Notes:

• If you use Contract.Requires<TException> you will receive an assert message telling you that you need to use the rewriter
  
• Alternatively, leave your pre-conditions as old-fashoned if-then-throw-statements, and end them with EndContractBlock, (contract tools recognize them as legacy-require statements).
  Beispiel aus den FAQs:

  void MyMethod(Foo foo)
  {
     if (foo == null) throw new ArgumentNullException(...);
     Contract.EndContractBlock();
     ... normal method code ...
  }
  

Setting Attribute value in VB.NET XML Literals

You the receive compile error when using XML literals and try to set an attribute using quotation marks…

Error message: "Expected matching closing double quote for XML attribute value."

Your code might look similar to this fragment:

Results in an error:

Dim output = From item In items
  Select <Item ID="<%= item.ID %>">
  </Item>

What's wrong? Just Remove the quotation marks. The <% %> syntax will insert them later.

Works fine:

Dim output = From item In items
  Select <Item ID=<%= item.ID %>>
  </Item>

The result as XML:

<Item ID="1">
</Item>
<Item ID="2">
</Item>

Disable Java update notification

As described here and here, this is what you need:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Update\Policy]
"EnableJavaUpdate"=dword:00000000
"EnableAutoUpdateCheck"=dword:00000000

Configure Windows Server to sync time with Internet Time (NTP) servers

This guide knows how to do it:

• "Note that you don't want to do this on a computer (PC or server) that is part of a domain, as this computer should pick up time from the Domain Controller.
• You should do this on the domain controller itself though. The DC, in turn, will hand out the correct time to the rest of the computers."

The .REG file:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters] "NtpServer"="pool.ntp.org" "Type"="NTP" [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient] "SpecialPollTimeRemaining"="pool.ntp.org" "SpecialPollInterval"=dword:00000e10

Download: TimeSync.zip

After restarting the Windows Time Service

net stop w32time

net start w32time

You can check when the last time synchronisation happend using

w32tm /query /status
