I've recently discovered Notepad++ and love it.
One problem with using Notepad++ is that you can't open up a fex with a right click in Developer Studio.

I did some digging around on the forums of Notepad++ and someone came up with a solution.

Check it out.
http://sourceforge.net/forum/message.php?msg_id=4732451&abmode=1

After reading the article I made a registry script and now right click works with Notepad++ in Dev. Studio.

Here is the script I made.

  
Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Notepad++_fex] 
@="Focus Executable" 
"EditFlags"=dword:00000000 

[HKEY_CLASSES_ROOT\Notepad++_fex\CLSID] 
@="{C0CF5A3C-3430-4E69-A178-2A6801AE26CD}" 

[HKEY_CLASSES_ROOT\Notepad++_fex\DefaultIcon]
@="C:\\ibi\\DevStudio76\\bin\\gfaview.dll,-30056"

[HKEY_CLASSES_ROOT\Notepad++_fex\shell] 
 
[HKEY_CLASSES_ROOT\Notepad++_fex\shell\edit] 
 
[HKEY_CLASSES_ROOT\Notepad++_fex\shell\edit\command] 
@=""C:\Program Files\Notepad++\notepad++.exe\""

[HKEY_CLASSES_ROOT\Notepad++_fex\shell\edit\command]
@="\"C:\\Program Files\\Notepad++\\notepad++.exe\" \"%1\""

[HKEY_CLASSES_ROOT\.fex] 
@="Notepad++_fex" 
"Notepad++_backup"="IBI.FocusExecutable.Icon"

You will probably have to make your own custom registry script based on your version of Developer Studio.
This one was created for Developer Studio version 7.60.
After you read the article you can manually make the changes to the registry or make your own custom script using a text editor. Save the script as fex.reg and run it.

This involves messing with your registry.
If your not comfortable with doing this then don't do it.
But this stuff isn't very complicated and worth trying.

Cool !

I haven't tried this approach yet, and am not that comfortable hacking the registry, if nothing else, the hacks have to be redone after reinstalls.

I use Notepad++ to launch WF files by right clicking them in Explorer. The NP++ install adds itself to the right-click menu, so this is easy to do, and I always have an Explorer window open anyway...

I use Edit Plus. It appears in the menu when one right-clicks a procedure.
Edit Plus can also colour-code your MASTER and FEX files
It also can complete some typing:
TABLE
DEFINE
MATCH

Notepad++ coloration files

userDefineLang.xml in documents and settings\user\application data\notepad++
