Windows Logo

Do you recently installing/uninstalling a new program and noticed that the program add some link/shortcut on Explorer context menu that you don’t like? If the program doesn’t have a preferences option to remove the context menu, you can remove it manually using Windows registry editor (regedit.exe).

First, make sure you login as an administrator or you have Administrative access to run Windows registry editor (regedit.exe).

• Start Windows registry editor (regedit.exe) from Start Menu | Run… and type regedit.exe
• Point the registry to:
  HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers
• For example, I would like to remove WinZip from Windows Explorer context menu, right click on WinZip key and choose Delete.
  
• Confirm it and voila! the WinZip context menu is now disappear from Windows Explorer context menu.

This is not a DownThemAll bug. This problem occur because of User Access Control in Windows 7 that prevent creating and/or modifying files (including newly created downloaded files) on some directory without Administrator access.

To solve this problem, you either need to start the Mozilla Firefox browser as Administrator or disable Microsoft Windows 7 User Access Control (UAC) completely. I prefer the first option, because it is only affect to the browser, not to the entire running application.

Hope this helps!

But there’s one thing missed: there is no Open with Notepad++ option on Windows Explorer context menu when I try to right-clicking on text files. I guess this is a bug from Notepad++. I am using Notepad++ v5.5.1 Unicode.

Try Googling about this problem and I found one working solution using Registry patch. Just copy and paste the following code to Notepad, save it as patch.reg file, and execute it. Voila!

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\*\shell\Open with Notepad++\command]
@="\"C:\\Program Files (x86)\\Notepad++\\notepad++.exe\" \"%1\""

For example, I have a string in a line:

$line= "Seq[03] Command : CREATE("A") Seq[04] Command : CREATE("B") Seq[04] error: 5006 Seq[03] error: 5006 Seq[05] Command : DELETE("A") Seq[05] error: 5006 ";

And I could capture all the Command without the error code using the following regular expression:

m/Seq\[[0-9]{2}\].+Command.+\(.+\)/gi

and the Perl code to show all string matching string:

while( $line =~  m/Seq\[[0-9]{2}\].+Command.+\(.+\)/gi ) {
       print $& . "\n";
}

But it doesn’t work as I expected because of the “greediness” of .+ and/or .*. The above code will match:

Seq[03] Command : CREATE("A") Seq[04] Command :
CREATE("B") Seq[04] error: 5006 Seq[03] error: 5006 Seq[05] Command : DELETE("A")

I expect the following output:

Seq[03] Command : CREATE("A")
Seq[03] Command : CREATE("B")
Seq[03] Command : DELETE("A")

To get the matching output as I expected, I need to modify the greedines the regular expression to a non-greedy one. How? After .+ and/or .* you need to add a question mark ? so the regular expression is now become:

m/Seq\[[0-9]{2}\].+?Command.+?\(.+?\)/gi

The following code is the full Perl code:

#!/bin/perl
$line= "Seq[03] Command : CREATE("A") Seq[04] Command : CREATE("B") Seq[04] error: 5006 Seq[03] error: 5006 Seq[05] Command : DELETE("A") Seq[05] error: 5006 ";
while( $line =~  m/Seq\[[0-9]{2}\].+?Command.+?\(.+?\)/gi ) {
       print $& . "\n";
}

To use Convert class in Microsoft.VisualBasic library, you need to include the following code at the top of your code:

using Microsoft.VisualBasic;

Converting binary String value to Int32 use Convert.ToInt32(String value, Int fromBase) method. value is the binary String value to convert, and formBase is 2 to indicate that value is binary.

String value = "00000010";
Int32 decimal = Convert.ToInt32(value, 2);

Converting decimal (Int32) value to hexadecimal is as easy as converting binary String to Int32 by using Convert.ToString(Int32 value, toBase) method. value is the decimal value to convert to hexadecimal, and toBase is 16 to indicate that value is converted to 16-base (hex).

Int32 value = 13;
String hex = Convert.ToString(value, 16);

You can combine both method to do binary to hex conversion like the following example:

String binary = "00000010";
String hex = Convert.ToString(Convert.ToInt32(binary, 2), 16);

netsh interface ip set address [Connection Name] [Source] [IP] [Netmask] [Gateway] [Metric]

• [Connection Name] is the connection name which the network adapter is assigned to. You can see the name in the Control Panel Network Connections panel or by using the ipconfig /all command from the command prompt.
• [Source] is the source of IP address, whether it is static or dhcp. If you set to dhcp. You can ignore all other remaining parameter.
• [IP] is the IP address you set.
• [Netmask] is the network mask for the IP address.
• [Gateway] is the the gateway IP address.
• [Metric] is the metric for the gateway.

for example:

netsh interface ip set address "Local Area Connection" static 192.168.1.10 255.255.255.0 192.168.1.1 1

The above command will set your “Local Area Connection” network adapter IP to static IP 192.168.1.10 with netmask 255.255.255.0, gateway 192.168.1.1, and gateway metric 1.

To set DNS server for the network connection use the following command:

netsh interface ip set dns "Local Area Connection" static 202.134.1.10

To add a second DNS server, use the following command:

netsh interface ip add dns "Local Area Connection" 202.134.0.155 index=2

OK, have a good try.
