For the past several years through last night (2017-03-02), ctrl+e in a code file has executed that file DO <currentfile>.prg Today it does nothing. both ctrl and e work for other purposes, and I've rebooted the computer. I've not yet found an obvious way to access application keybindings.
VFP 9.0 SP2
Only files opened with MODIFY COMMAND <filename> are eligible for execution. Other file types are opened with MODIFY FILE and are not eligible.
(Starting up I had edited a MODIFY FILE to open my program, not realizing that there were two different MODIFY commands)

I have spent a very long time researching this. Most of the solutions were posted PRIOR to April 2018, and involved working your way through the "settings" to get to "Choose default Apps by file type".
Choose default Apps by file type
In previous attempts to assign an app to ".rex" I managed to assign it to Notepad. (At that time, I could not find any way to find an ".exe" on my C: drive.)
So as you can see, if you click on Notepad next to the .rex extension, the only option is to go to the "App store".
And as expected, if you click on App store, nothing is found...
App store - no app's found.
So from what I've read in multiple forums, PRIOR to April 2018, Windows 10 still had a way to "browse your hard drive" to find an ".exe". (Just like in older Windows versions.) After some update in April 2018, that capability no longer exists.
In the POST April 2018, has anyone found a way to assign a file extension to an ".exe" on the hard drive???
I think this question would be more suitable for SuperUser (well, unless you want to do it via a program :) ).
Anyway, here's a way of doing things from console (Cmd). I've tried it 1 or 2 years ago, I just tried it now, so it works regardless of Win (10) version.
Start the process from scratch:
Open a Command Prompt window. Create a new file that the OS doesn't know anything about. I chose the extension .zzz:
e:\Work\Dev\StackOverflow\q052008516>ver
Microsoft Windows [Version 10.0.17134.228]
e:\Work\Dev\StackOverflow\q052008516>dir /b
e:\Work\Dev\StackOverflow\q052008516>:: Create a dummy .zzz file
e:\Work\Dev\StackOverflow\q052008516>echo Some dummy text>file.zzz
e:\Work\Dev\StackOverflow\q052008516>dir /b
file.zzz
Try opening the file (DblClick) from a file browser (it's not relevant, but I use Total Commander), or by typing its name in Cmd. That will yield the dreaded dialog:
Create a new file type and associate our extension with it. [MS.Learn]: assoc utility is used to do the job. First, check if such association doesn't already exist:
e:\Work\Dev\StackOverflow\q052008516>:: No output means no association
e:\Work\Dev\StackOverflow\q052008516>assoc | findstr ".zzz"
e:\Work\Dev\StackOverflow\q052008516>:: Same command for a different extension
e:\Work\Dev\StackOverflow\q052008516>assoc | findstr ".txt"
.dic=txtfile
.exc=txtfile
.log=txtfile
.scp=txtfile
.txt=txtfile
.wtx=txtfile
e:\Work\Dev\StackOverflow\q052008516>:: Create a new FileType (ZZZFile) and associate our extension with it
e:\Work\Dev\StackOverflow\q052008516>assoc .zzz=ZZZFile
.zzz=ZZZFile
e:\Work\Dev\StackOverflow\q052008516>assoc | findstr ".zzz"
.zzz=ZZZFile
No change when trying to open the file.
Associate the file type (ZZZFile, from previous step) with a command. Use the [MS.Learn]: ftype tool for the task. Again, check if the file type is not already associated (this only makes sense if the file type existed before previous step):
e:\Work\Dev\StackOverflow\q052008516>:: As usual, no output means no association
e:\Work\Dev\StackOverflow\q052008516>ftype | findstr ZZZFile
e:\Work\Dev\StackOverflow\q052008516>:: Same thing for txtfile
e:\Work\Dev\StackOverflow\q052008516>ftype | findstr txtfile
txtfile=%SystemRoot%\system32\NOTEPAD.EXE %1
e:\Work\Dev\StackOverflow\q052008516>:: Associate ZZZFile with notepad
e:\Work\Dev\StackOverflow\q052008516>ftype ZZZFile=%SystemRoot%\system32\notepad.exe %1
ZZZFile=C:\WINDOWS\system32\notepad.exe %1
e:\Work\Dev\StackOverflow\q052008516>ftype | findstr ZZZFile
ZZZFile=C:\WINDOWS\system32\notepad.exe %1
Try opening the file again (from Cmd), and voilà:
Summary:
In order to open with Notepad files having .zzz extension, there are only 2 commands that need to be remembered from this whole (and pretty long) answer:
assoc .zzz=ZZZFile
ftype ZZZFile=%SystemRoot%\system32\notepad.exe %1
Notes:
My user has (super) administrative privileges, but I guess they shouldn't impact differently depending where the action is performed from (Cmd or UI (if possible)), in other words users that don't have the required privileges, won't be able to do it, no matter what they would try
Apparently, there is a (pretty dark) nebula on this topic, that my knowledge wasn't yet able to "decipher". In my example, I constantly compare the .zzz results to .txt. Yet a big surprise: Notepad++ and not Notepad is used to open txtfile (.txt only), in spite of the above output
Update #0
I did a little more digging on the .txt mystery. Facts:
FType shows Notepad as opening program
It is actually opened by Notepad++ (in Cmd and PS)
In Choose default apps by file type, Notepad++ is shown
So apparently, it's more than meets the eye (over the years, I got used to MS's way of doing things which in some cases seems to be (but maybe it's me who didn't have all the pieces) illogical).
I've also found out many resources like:
[MS.Technet.Blogs]: Windows 10 – How to configure file associations for IT Pros? which mentions the command:
dism /online /export-defaultappassociations:"file.txt"
[XDADevelopers]: Programatically set default file associations which mentions the reg keys:
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\${EXT}
HKCR\${EXT}
I couldn't find anywhere a clear algorithm of how an executable is chosen to run a file with a certain extension. I can think that the 2 keys above are queried, but I'm 100% sure there's more. Not to mention that I've ran into an even stranger problem (for a regular user on my Win 10), for .py files:
FType (and Assoc) reported everything as above
In Choose default apps by file type, Python was shown (just like in my Super Admin user's case)
Attempting to run the file from Cmd, yielded the dialog at the beginning
It worked from PS
Sadly, I selected Python from the dialog, before taking a look at the registry keys (and now it works), so I can't do any more debugging (and also, switching users is annoying).

I am looking for a way to have my Notepad++ window open for editing my code and run it line by line or by sections (more than 1 line) while I am editing. It would be like having a real IDE; the output could be shown in the same window (Notepad++) or directly in the Octave window.
I have tried what many many sites say. That is, writing this:
C:\Software\Octave-3.6.4\bin\Octave\Octave-3.6.5.exe "$(FULL_CURRENT_PATH)"
in the Run window in Notepad++, saving and giving it a shortcut. However, it is still not working. When I tried to run it, the black window starts showing-up but then it disappears and nothing else happens. In my Notepad++ window I have only one line (for now) where I have tried just "b=4" or "3*4". I have done this with and without semicolon at the end. Nothing happens.
I have Windows 8.0, Notepad 6.5.5 and Octave-3.6.4. I already change the octaverc file in Octave to make it work with Notepad++. I have work already only in the command line in Octave and is working fine. The Octave I installed was exactly "octave-3.6.4-vs2010-setup", it says it was compiled for Visual Studio 10. Is that the reason why this is not working?
Any help will be appreciated...
regarding Octave not processing the command: use supposed command line outside the N++ and see if it works. If not, find a way to make it working, then transfer it back to N++ (and use the token "$(FULL_CURRENT_PATH)" instead of concrete filename)
regarding running the code in smaller portions: if you app can accept the code directly in the command line (SQL command line tools I use can do this), then you can use token "$(CURRENT_WORD)" what stands for content of current selection (all tokens are in wiki)
I have perl scripts which were running in Windows 7 just fine as of this morning. I made the mistake of using NotePad as the default for opening/editng my .pl files. Now, when I attempt to run the unedited .pl files from a DOS prompt, the script does not execute but opens the associated source code file in Windows Explorer. This is the same for all my .pl files no matter the complexity (including classic "hello world".
I have been researching changes need to the registry - it all looks fine. Tried assoc and ftype changes - nothing. Tried reinstalling ActivePerl - no solution.
You don't need to go into the Registry.
Go into Windows Explorer.
Find a file that ends in a *.pl suffix.
Right click on it and bring up the Context menu.
Select "Open With" (It might just be Open... with an ellipse after it. I don't have a Windows machine at the moment to verify this). This will bring up a dialog box with all the various programs. NOTE: Perl may not be listed in the initial set of programs. No worry, just navigate to it.
On the bottom of the dialog box is a checkbox (Something like open all extensions with this program). Make sure that checkbox is checked.
After this, all files that end with *.pl will open with Perl instead of Notepad.
It is highly likely that someone did this with a Perl script in order to edit it, and messed up the file association.
However, who ever did this should be doped slap -- not for messing up the file association, but for editing a program with Notepad. Bad Developer! No doughnuts for you!
Programs should be opened with a Program Editor. If you're a real he-man, you can use VIM. VIM is a fast, and powerful program editor, but you will need to spend an internship at the feet of a VIM Ninja master in order to learn how to use it. Your first three to six months with VIM will be What a idiotic program! This is awful. Who wrote this crap?. Then, one day, you will understand its power and efficiency. You will be one with the program.
If you aren't brave or fearless or don't have six months to waste learning a programming editor, you can use Notepad++. Compared to VIM Notepad++ is like driving a Minivan. It's safe, it's practical, and it gets the job done.
Both editors do Syntax Highlighting which can help you find issues. Both, (VIM can -- I think Notepad++ can too) offer help with syntax and usage. Both can edit a file without messing up the line endings (They'll both detect whether a file has Unix or Windows line endings and keep those or allow you to convert them). Both will number your lines, have extensive cut/paste buffers, powerful search and replace features. And will not mess up your file encoding. Both offer visual diffing between files and do automatic backups when you edit a file.
Finally, these two editors will embed themselves into the context menu you get when you right click on a file. You can edit a file by clicking on it, and selecting VIM or Notepad++ directly from the context menu. No need to select "Open with..." and possibly mess up the file suffix association.
Never ever use Notepad to edit a program.
Sounds like your .pl extention association is now set to Notepad rather than perl.exe. If you are too busy to fix that, just type "perl yourscript.pl" in a command promot window to start the perl interpreter and to send your script to it to run.
See this answer to fix the association:
File Type .pl Association and Using cmd.exe to Run the Script
I have the same problem. None of the method mentioned above solve the problem. The problem actually came from Windows 7! Windows 7 Doesn't allow you to associate .pl to perl.exe in c:\Perl64 directory, for whatever reason.
Here is the solution:
If you look at c:\Perl64\Bin directory (or the path where your ActivePerl binary installed), you'll see another file: Perl5.14.2.exe. This is the same file as perl.exe in same directory but with version number attached as postfix in the name.
You can associate .pl file to that Perl5.14.2.exe instead of perl.exe. Bingo, it works now.
I am trying to open a .chm file.
I downloaded the source, extracted it, and double clicked on Waffle.chm and clicked "Open" but no matter what element in the chm file I click, I get the message:
Navigation to the webpage was canceled.
What you can try:
Retype the address.
What's going on here?
Summary
Microsoft Security Updates 896358 & 840315 block display of CHM file contents when opened from a network drive (or a UNC path). This is Windows' attempt to stop attack vectors for viruses/malware from infecting your computer and has blocked out the .chm file that draw data over the "InfoTech" protocol, which this chm file uses.
Microsoft's summary of the problem: http://support.microsoft.com/kb/896054
Solutions
If you are using Windows Server 2008, Windows 7, windows has created a quick fix. Right click the chm file, and you will get the "yourfile.chm Properties" dialog box, at the bottom, a button called "Unblock" appears. Click Unblock and press OK, and try to open the chm file again, it works correctly. This option is not available for earlier versions of Windows before WindowsXP (SP3).
Solve the problem by moving your chm file OFF the network drive. You may be unaware you are using a network drive, double check now: Right click your .chm file, click properties and look at the "location" field. If it starts with two backslashes like this: \\epicserver\blah\, then you are using a networked drive. So to fix it, Copy the chm file, and paste it into a local drive, like C:\ or E:. Then try to reopen the chm file, windows does not freak out.
Last resort, if you can't copy/move the file off the networked drive. If you must open it where it sits, and you are using a lesser version of windows like XP, Vista, ME or other, you will have to manually tell Windows not to freak out over this .chm file. HHReg (HTML Help Registration Utility) Utility Automates this Task. Basically you download the HHReg utility, load your .chm file, press OK, and it will create the necessary registry keys to tell Windows not to block it.

Windows 8 or 10? --> Upgrade to Windows XP.
"unblocking" the file fixes the problem. Screenshot:
Win 8 x64:
just move it to another folder or rename your folder (in my case: my folder was "c#").
avoid to use symbol on folder name. name it with letter.
done.
In addition to Eric Leschinski's answer, and because this is stackoverflow, a programmatical solution:
Windows uses hidden file forks to mark content as "downloaded". Truncating these unblocks the file. The name of the stream used for CHM's is "Zone.Identifier". One can access streams by appending :streamname when opening the file. (keep backups the first time, in case your RTL messes that up!)
In Delphi it would look like this:
var f : file;
begin
writeln('unblocking ',s);
assignfile(f,'some.chm:Zone.Identifier');
rewrite(f,1);
truncate(f);
closefile(f);
end;
I'm told that on non forked filesystems (like FAT32) there are hidden files, but I haven't gotten to the bottom of that yet.
P.s. Delphi's DeleteFile() should also recognize forks.
The definitive solution is to allow the InfoTech protocol to work in the intranet zone.
Add the following value to the registry and the problem should be solved:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000001
More info here: http://support.microsoft.com/kb/896054
Go to Start
Type regsvr32 hhctrl.ocx
You should get a success message like:
" DllRegisterServer in hhctrl.ocx succeeded "
Now try to open your CHM file again.
other way is to use different third party software. This link shows more third party software to view chm files...
I tried with SumatraPDF and it work fine.
I fixed this programmatically in my software, using C++ Builder.
Before I assign the CHM help file, Application->HelpFile = HelpFileName, I check to see if it contains the "Zone.Identifier" stream, and when it does, I simply remove it.
String ZIStream(HelpFileName + ":Zone.Identifier") ;
if (FileExists(ZIStream))
{ DeleteFile(ZIStream) ; }
There are apparently different levels of authentication. Most articles I read tell you to set the MaxAllowedZone to '1' which means that local machine zone and intranet zone are allowed but '4' allows access for 'all' zones.

This is how my registry looks (I wasn't sure it would work with the wild cards but it seems to work for me):
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000004
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"UrlAllowList"="\\\\<network_path_root>;\\\\<network_path_root>\*;\\ies-inc.local;http://www.*;http://*;https://www.*;https://*;"
As an additional note, weirdly the "UrlAllowList" key was required to make this work on another PC but not my test one. It's probably not required at all but when I added it, it fixed the problem. The user may have not closed the original file or something like that. So just a consideration. I suggest try the least and test it, then add if needed. Once you confirm, you can deploy if needed. Good Luck!
Edit: P.S. Another method that worked was mapping the path to the network locally by using mklink /d (symbolic linking in Windows 7 or newer) but mapping a network drive letter (Z: for testing) did not work. Just food for thought and I did not have to 'Unblock' any files. Also the accepted 'Solution' did not resolve the issue for me.
Moving to local folder is the quickest solution, nothing else worked for me esp because I was not admin on my system (can't edit registery etc), which is a typical case in a work environment.
Create a folder in C:\help drive, lets call it help and copy the files there and open.
Do not copy to mydocuments or anywhere else, those locations are usually on network drive in office setup and will not work.
When deleting a folder that contains a file that is in use, it is common to see the following Windows 7 message,
"The action can't be completed because the folder or a file in it is open in another program."
I commonly have 10-20 programs open, 30-40 folders open, etc. In short, I have many executables running and many windows explorers open.
Does anyone know a simple trick to determine which program is using the file?
Does anyone know a simple trick to determine which file is blocking the delete operation?
This information would be highly useful to display in the Windows 7 'folder in use' dialog, but it is missing.
Consequently I have to close many of my open applications and folders to complete the delete operation. This is annoying because I have to re-open them after deleting them.
Have you seen this other question or this one?
I use to run ProccessExplorer and Find for the blocked folder.
Closing the application Malwarebytes allowed me to delete what I needed to via Windows Explorer.
