private string GetVersion()
{
      return Assembly.GetExecutingAssembly().GetName().Version.ToString();
}

Here is an example example,  in following code we try to replace c:\foo to d:\bar for a given directory name.

my $dir = "c:\\foo\\test";
my $foo = " c:\\foo";
my $bar = " d:\\bar";
$str =~ s/$a/$b/g;    # this prints c:\foo\test

The code will not work as backslashes are escaped to \\ in regular expression pattern, after using \Q and \E to escape backslashes in pattern,

my $dir = "c:\\foo\\test";
my $foo = " c:\\foo";
my $bar = " d:\\bar";
$str =~ s/\Q$a\E/$b/g;    # this prints d:\bar\test

Now we get what we expected.

\E end case modification (think vi)

\Q quote (disable) pattern metacharacters till \E

my $dir="d:\\bin";

Then $dir will be included in new $ENV{PATH}

sub ExecuteCommand {
my $cmd= $_;
my @cmdoutput = `$cmd`;
for $line (@cmdoutput) {
print $line;
}

Now just change your code from system($command) or `$command` to ExecuteCommand($command) and you will see all command output are redirected to console.

En, good but …

I want to see the command that it’s running

Just add print following line prior the call of command.

print “Now running $cmd …\n”;

or call your logging subrountine.

I want to know return code of $cmd

Use my $cmdexitcode = $? >> 8; to get the return code of $cmd and then add     return $cmdexitcode; at the end of ExecuteCommand

I want to pass more than one command to ExecuteCommand

Try this version

sub ExecuteCommand {
@cmdlist = (@_);
my $cmd = join(” \& “, @cmdlist);
my @cmdoutput = `$cmd`;
my $cmdexitcode = $? >> 8;
for $line (@cmdoutput) {
print $line;
}
return $cmdexitcode;
}

Now you should call ExecuteCommand like this when you want to pass more than one command.

push @cmdlist, $cmd1;
push @cmdlist, $cmd2;
push @cmdlist, $cmd3;
ExecuteCommand(@cmdlist);

And $cmd1, cmd2, cmd3 will be run in one context shell.

Enable SpellChecker functionality on TextBox or RichTextBox is as easy as just setting SpellCheck.IsEnabled to True on the controls.

   <TextBox SpellCheck.IsEnabled="True" />

Then all misspelled words will be underlined with a wavy red line in run time. And when user right clicks on misspelled word, a list of suggestion words will be displayed.

Example

Update

As per this MSDN thread, you need to install language pack for .NET Framework 4.0 to enable spell check for some language in your WPF4 applications. For example, if you want to spell check for German, you need to install .NET Framework 4.0 German language pack on your machine. So far the .NET Framework 4.0 language pack is not available, but it will be soon.

Use coalescing operator to make your code a bit more readable.

public string Foo

Does this look better? The ?? operator is called the null-coalescing operator and is used to define a default value for a nullable value types as well as reference types. It returns the left-hand operand if it is not null; otherwise it returns the right operand. More information on ?? can be found at http://msdn.microsoft.com/en-us/library/ms173224.aspx
