Using External JavaScript Files with Google Analytics

For basic page tracking, put the code in an external file.

Then you can use this

<script src="/js/googleAnalytics.js" type="text/javascript"></script>

instead of

<script type="text/javascript">
  var _gaq = _gaq || [];
  _gaq.push(['_setAccount', 'UA-XXXXX-X']);
  _gaq.push(['_trackPageview']);
  (function() {
    var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
    ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
  })();
</script>

Add to files, right before the closing head tag.


googleAnalytics.js

var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-XXXXX-X']);
_gaq.push(['_trackPageview']);
(function() {
  var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
  ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
  var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();

PInvoke SetWindowText PowerShell Script

P/Invoke examples for the SetWindowText Windows API Function.
These examples set the window text/title for Notepad.exe.

#get notepad window handle
$notepad = get-process notepad
$notepad.mainWindowHandle  //100000, intptr structure

$pinvoke::setWindowText($notepad.mainWindowHandle, "a")

#auto-convert int to intptr
$pinvoke::setWindowText(100000, "b")

#create intptr
#out-null to suppress bool result
$pinvoke::setWindowText((new-object intPtr(100000)), "c") | out-null

$pinvoke::setWindowTextCustomWrapper(100000)

Implementation #1 simply exposes the SetWindowText method, the member definition uses C# syntax.

$pinvoke = add-type -name pinvoke -passThru -memberDefinition @'

[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern bool SetWindowText(IntPtr hwnd, String lpString);

'@

Implementation #2, same as #1 but written on one line.

$pinvoke = add-type -name pinvoke -passThru -memberDefinition '[DllImport("user32.dll", CharSet = CharSet.Auto)]public static extern bool SetWindowText(IntPtr hwnd, String lpString);'

Implementation #3, SetWindowText is private, add custom wrapper method.

$pinvoke = add-type -name pinvoke -passThru -memberDefinition @'

[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern bool SetWindowText(IntPtr hwnd, String lpString);

public static void SetWindowTextCustomWrapper(IntPtr handle)
{
  string customText = string.Format("handle: {0}", handle);
  SetWindowText(handle, customText);
}

Git Custom Difftool Configuration

Original solution by David Tchepak: Setting up Git difftool on Windows

This example shows the configuration for ExamDiff Pro.
Tested on Windows 7 and msysgit version 1.7.3.1

1. Set the path environment variable to include "c:\program files\git\cmd\;"
2. Create a shell script wrapper file, note the forward slashes in the executable path

#c:\program files\git\cmd\diff.sh
#!/bin/sh
"c:/program files/examdiff pro/examdiff.exe" "$1" "$2" | cat

3. Edit the .gitconfig file

#c:\users\john\.gitconfig
[diff]
    tool = examdiff
