I just installed WinGHCi. When I try to load an .hs file with Ctrl+L, it opens the file browser in C:\Program Files (x86)\Haskell Platform\2012.2.0.0\winghci which is where I installed this. I don't want it to go there by default, I keep my code files in a different directory on a different drive and I don't want to have to navigate to D:\MyPath\Haskell every time I load a file.
I tried to set the "Start in" field of the shortcut I use to launch WinGHCi but it changed nothing.
How can I make WinGHCi look in my own directory by default?
It opens in the last directory you opened a .hs or .lhs from.
Try opening something from the folder you want, exit, restart.
Did it restart where you were?
Try working like that for a while, and if you like it (I do) then you're fine.
If you really do want to go to the same place every time, perhaps there's a way.
I can't find any setting to control this, but the information is stored in the registy.
Mine is at
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Haskell\WinGHCi 1.0.6]
"WorkingDir"="D:\\Files\\Andrew\\prog\\haskell"
You can save your version of that as resetghci.reg:
To make your own, open regedit and first try the same location. If not, search for WinGHCi.
You can export that subtree but you get the whole lot including recent expressions etc, which I don't think you should reset. Save that as ghcioriginal.reg just in case. Edit away all the lines except WorkingDir and save as resetghci.reg
When you double-click it it will ask you if you're sure you want to add that info to the registry. Yes you are.
Untested:
What follows works on older versions, but Microsoft seem to be going off .pif files and the start command, and I'm not able to test this in Windows 7.
Make a text file called ghci.bat in the same folder as the .reg you made. In it put
#echo off
regedit resetghci.reg
start WinGHCi
You might need to specify the full path to WinGHCi.
The start command is the windows equivalent of making a background process from a shell prompt, so this should terminate immediately.
Make a shortcut to ghci.bat (it will be called ghci.pif) and set it to open minimised and put a nice lambda icon on it (nick it from the winghci executable).
Pop that on your desktop, start menu or shortcut bar, and when you use it, you'll be popped back to your standard location.

It's maybe stupid question, but what happens behind the scenes when i double click the word app, or .exe app?
For 'Non-Developer' it just opens the file in right environment after doubleclicking. But I would like to know, how is it done, how can the file manager know what to open? (.docx in word, .txt in texteditor,etc...)
+ I would like to know how can I do that in Node.js, is it the best way to use child_process and if statements for every suffixes?
There is a file association to tell Windows how to treat a certain file extension. You can type assoc in a Windows Command Prompt to see them. As an example:
C:\test>assoc .txt
.txt=txtfile
So Windows knows now, that the file with the extension .txt is a txtfile.
ftype defines, how that filetype is to be handled:
C:\test>ftype txtfile
txtfile=%SystemRoot%\system32\NOTEPAD.EXE %1
So whenever you doubleclick on a file, Windows checks if it is associated with any filetype. Then it looks up, how to handle that filetype and executes that command (in the example above, it opens Notepad with the filename as a parameter).
Both assoc and ftype are able to change the settings (for example to open .txt files with another editor). But if you try that, do yourself a favor and note the original settings, so you are able to revert your changes when needed.
The changes can also be done directly in the registry (not recommended, when you are not experienced in handling the registry)
For Node.js, you can use child_process to shell out to the start command which does similar things as the File Explorer.
E.g. start some/path/to/file.docx will open that file in the default program associated with the format.
The problem:
I'm currently working on a programming language, which uses a simple python interpreter. The interpreter loops over every line with a bunch of if-statements.
The file extension I'd like to use is .ccp.
So far my progress. I want the computer to recognise .ccp files as a CalcScript file, and open it with the script.
I don't want to have a default filename which I can open using text = open("filename.idk","r").read(), I want to open a file like a 'normal' file. You double-click on the file in explorer, and it opens it in the python script. Regardless of the filename.
What I've tried:
Tinkering with the default applications in settings
Tinkering in regedit
Converting my .py file to .exe
Scouering the internet
My code:
https://github.com/AnonymousPixel/CalcScript
Sorry for bad English if there was any.
Summarizing my comments on the question, you can follow the steps below to achieve what you are asking:
Use sys.argv to access the command line arguments. For example the following script will just print all the arguments given to it:
import sys
print("Given arguments: ", str(sys.argv))
Let's name it myprogram.py.
You can then call it (I think) with: python myprogram.py arg1 arg2 arg3 and it will run and print the command line arguments.
Notice that the first argument (sys.argv[0]) is the script's path. So arg1 would be sys.argv[1], arg2 would be sys.argv[2] and so on.
I am saying to use sys.argv because as far as I remember double clicking a file with an extension which has a default opening program, will open that program with the file path as an argument.
Next step is to package your python script to an executable. This has been already asked and answered for example here (which is a duplicate, where you can follow the question which came before it to see even more examples). I used PyInstaller to test it (and on Windows OS). My command was like:
pyinstaller myprogram.py
... and it generated some folders and files. Specifically the folder dist\myprogram contained the executable along with its dependencies. You can then run your program by double clicking on it in the dist\myprogram folder. It should pop a CLI window, printing the arguments (ie only the program's path, since we called it without any other) and immediately exit. Or you can open a CLI window and run it with a command like:
myprogram argument1 argument2 argumentN
(supposing your current working directory is dist\myprogram) and it will indeed print the arguments.
Finally you have to set it up as the program which by default opens files with .ccp extension. On Windows 10, you can do this via:
Open up File Explorer.
Find a file with .ccp extension (or create one).
Right click on it.
Click on Properties on the dialog that pops up.
Go to General tab (if you are not already there) on the dialog that pops up.
On the Open with: section there is a button which reads Change. Click it.
Select More apps at the bottom of the dialog.
Make sure you have the Always use this app to open .ccp files checkbox selected.
Scroll to the bottom of the dialog and click on the blue text which prompts for manually selecting the default app, which in turn pops up a file chooser. I am not running on English language so it is a bit difficult to translate it exactly (I followed some online pages to actually see the default translation for the previous steps).
Select your executable as the default.
Confirm your choices by selecting Ok, Apply or anything else required.
Then you will also be able I think to change this extention later via:
Settings --> Apps --> Default Apps --> Choose default apps by file type.

How do you make a PC unzip a downloaded file with one click in Chrome? Macs do this, why not PCs?
On my Mac, when I download a .zip file, it shows in the bottom bar of Chrome. If I click once on that download in the Chrome bottom bar, it unzips the archive into the same directory ("Downloads") without any further interaction from me.
How can a PC user get a file to unzip with that same convenience? Everything I've tried requires you to go to make two or three steps.
Here's how to do it. It is not nearly as seamless and quick as on a Mac, but it works without any user interaction by monitoring your download folder for archives. When one shows up in the folder, it automatically unzips the archive and can optionally delete the .zip, or run a command line, or what-have-you. On a slow PC I tested it on, it took about 40 seconds to recognize there was a new archive and to process it. Hopefully that's faster on faster PCs.
Here are the basics:
download ExtractNow onto PC from http://www.extractnow.com
in the Settings tabs, under Monitor, select the path to the folder want to monitor and check the "Automatically extract" checkbox.
That's basically it.
Additionally you can run a command. I needed to do something a little unusual - open an .html file from the just-expanded archive using Microsoft Word - and I was able to get it to do that automatically. Here's what I entered in the Process tab under the "Archive operation complete" section:
check the "Run a program" checkbox
in the Command: box, enter this:
winword {ArchiveFolder}"{ArchiveName}.html"
You can tweak that for your circumstances. The point is that ExtractNow can pass info about the archive (the name, the path, etc.) in bracketed, named variables so that you can use them to invoke other commands or processing.
I don't love the time lag, but it completely does what I wanted and more. Cheers!
I am trying to edit the corflags file so that I can run 32bit applications on a 64 bit pc but everytime I try to edit the file using something like corflags.exe assembly /32bit+ it comes up with the error message cf001 could not open file for writing.
Now I have tried a lot of different options such as:
Running in administrator mode;
Finding the file using a search and checking read only is not ticked
Checking that user full control is ticked
Tried to set the whole folder to non read only
When trying the whole folder, it goes through looking like it has set read-only, but then I click OK and re-right click on the whole folder, the box is filled in (not ticked) does this mean that part of the folder is read only and why does it reset to read only?
I just faced the same problem and have tried the same things.
Run cornflags from an elevated ("Run as administrator") Visual Studio Command Prompt. I did the same for a copy of the original .exe just to make sure no other process was using the program.
Create a copy of the file you intend to target with CorFlags.
(e.g. "WcfServiceHost.exe" --creates--> "WcfServiceHost - Copy.exe")
Rename the original file to something else:
(e.g. "WcfServiceHost.exe" --> "WcfServiceHose_Original.exe")
Rename to copy to the original file name
(e.g. "WcfServiceHose - Copy.exe" --> "WcfServiceHost.exe"
For my purposes, I created copies and named them describing their configuration:
Example:
WCFServiceHost_With32BitOn.exe
WCFServiceHost_With32BitOff.exe
Now I can destroy the WCFServiceHost.exe files and create them from these pre-modified copies. No more CorFlags operations necessary.
Note: this is basically a more verbose version of #RMalke answer and that answer should be marked as the answer.
I realise this is years later, but for anyone else looking, I found that the quickest way was to copy cmd and corflags.exe into the same folder as the one you want to edit. Then run cmd as admin from there.
I am trying to open a downloaded .exe file but it closes as soon as it opens. Is there any possible way so that I can open it for a longer duration to read the content.
It's probably a console application rather than a GUI application. Use the command prompt to run the .exe.
Do the following...
Hold down your Windows key on your keyboard and then tap "R".
This will bring up the Run dialog. Type in "cmd" (without the quotes). Hit enter.
(this will work in all Windows versions - browsing the start menu/screen differs in each version)
If you saved the file to c:\downloads and it's called myFile.exe, type
C:
cd C:\Downloads
myFile.exe
Some of the steps are a bit redundant - if you know what you're doing in the command prompt then skip as needed (but then you probably wouldn't be posting this question). This will work even if you saved the file to D:\downloads.
Another example - if you saved the file to D:\folderA\Folder with a space\ and the file is called "my file with a space.exe" then type
D:
cd "D:\folderA\Folder with a space"
"my file with a space.exe"
If there is an issue (eg it's a 64-bit executable and you're on 32-bit Windows) then you may get a better error message at the command line.
There are so many reasons why the executable does not run. Here are some ways to check what is going wrong:
Is it your .exe? Do you known the "normal" behavior?
When you download it manually, it the result the same?
Do you download the .exe manually or via your application?
Do you see any problem in your Windows Event Viewer?
Is it the same result if you try to download the .exe via different browsers (IE, FF, ...)?
More details are welcome!
The nuget.exe file is not a console GUI application but rather a console package. Once you've downloaded it, you'll want to place it in a folder outside your Downloads folder. For example, C:\NuGet\nuget.exe - then set it as a PATH variable so that it's executable from anywhere.
