I need to open the file using Windows 10 cmd. But when the file opens, I need Windows to show me a modal window "How do you want to open this file?". The system should do this even if it already has a program selected by default to open a certain type of file. Is it possible to do this?
To clarify my problem:
I need the console to run for example ".py" not through the standard Python.File="C:\Windows\py.exe " "%L" %*, and for example via VS Code. You might tell me about the VS Code CLI. But how to handle an event where the user will not have VS Code, but for example Pycharm, and the user will want to open it through it? That is why the question was posed in such a way that the user could choose through what to open the file already through the built-in modal window in Windows. In any case, I will be glad of any suggestion to solve my problem.
I tried to find something similar, but apart from the standard start something.som I didn't find it. And this is not a solution to the problem, because start starts the file in the program that is specified by default in the system. This program may not even be the one that the user ever chose later. I came across a similar question in Stackoverflow, where a person wanted to see which program was responsible for opening a file with a certain extension, where assoc and ftype were used, but they did not give the desired result.
I have a shell script file on my Desktop, and I have my preferences set so that when I double-click it, I'll be prompted for if I want to open it for edit, or run it. This works fine when double-clicking the file in my /home/[user]/Desktop folder, but when I double-click the file on my actual Desktop, it doesn't work.
Why is this and how can I run the file from my Desktop?
There can be a number of things that could be wrong in your environment. Could you provide us with the contents of the shell script and a screenshot of your preferences? Could you also expand on what doesn't work? What is the behavior you received after you attempted to run the shell script?

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.
I'm running Win7 in Parallels on a MacBook Pro. HTML help files (.chm) will not open, I get the "Navigation to the webpage was canceled" message. The files are not tagged as blocked in properties.
I've seen (but not tried) some registry entries that purport to solve the issue on a file-by-file or folder basis. I'm hoping for a more global solution.
Windows may be regarding the location of the .chm files as being on a network drive. There's a link to a program called HHReg on this page: http://social.msdn.microsoft.com/Forums/en-US/devdocs/thread/ef2b95e0-4198-4e1a-b876-314a23348b5e
