I've created a Windows Mobile application that opens, edits and closes a data file format. There're a couple of features I'd like to implemenet but I'm not sure how to go about it.
Create a file association so my data files have a custom icon.
Process the command line (if there is one) of my application so the user can select a data file to have it open in my application.
A SO search finds this, but doesn't go into detail of what I'm looking for. I know the file associations are in the registry, but I've never touched the WinMo registry so I'm a little clueless there. I've tried Google but maybe I'm not using the right keywords because I don't find much. Any pointers in the right direction would be greatly appreciated!
Take a look at HKEY_CLASSES_ROOT registry, under there are keys for file extensions, like '.txt', which the (default) value contains a name of another key (for '.txt' it is 'txtfile')
The 'txtfile' key contains keys for the default icon and the shell commands.
I suspect you can create keys and values similar to the ones that already exist for your application.
As for processing command line arguments, that should be the same as the desktop, just change your main function to have a string[] parameter and process them as necessary

static void Main(string[] args)
{
Application.Run(new Form1());

With Resilio Sync, I'm looking for a way to add multiple keys at once with a CSV file or run a script or copy-paste to a config file or whatever else.
Currently, I have a list of 10 keys I must set up on a laptop.
For each I have to click the '+' then 'Enter a key then copy paste the path to the folder I created for it.
I would prefer to have a list like this I could just load or parse with a script.
KEY,Folder Path,Selective sync
I6HK76FRZS...,C:\Sync\Folder1,No
76FRI6HKZS...,C:\Sync\Folder2,No
HK76FI6RZS...,C:\Sync\Folder3,No
.....
This would help reduce errors in copying and pasting information.
I've tried exploring the Internet and it looks like no one else has ever needed to do anything like this. :/ Hard to believe.
I've also tried researching the config file to see if I could add the information there.

Storing the information permanently in raw text on a config file does not sound ideal.
I was trying to get yapf configured for a Python project, and so I created a .style.yapf file, which VSCode did not recognize by its extension. I thought it was in TOML format, but when I changed the file association for .style.yapf to TOML, the parser shows an error (because values aren't quoted). So I tried changing the name of the file (not really a solution, because the tool is looking for a file with that name), and found that if I change it to a name ending in .cfg, VSCode seems to parse and highlight it appropriately. Unfortunately, there doesn't seem to be anything in the list of file associations corresponding to this file mode.
I expected to find a cfg mode in the file associations list, but there wasn't an entry with that name, nor was there an entry that used the same gear icon displayed next to the open file name in its tab (which I have been assuming is an indicator of the mode that VSCode is using to display and format the file).
Is there any way for me to get VSCode to tell me what the current file mode is for an open file? Or give me a list of the default associations?
I'm more interested in understanding the tools in general than solving the one minor annoyance that sparked the question, but I'll settle for a solution to that problem, too.
Edit: Here's the content of the .style.yapf file in question:
[style]
based_on_style = google
If I rename the file to .yapf.cfg (or any other name ending in .cfg, I believe), it gets handled properly, but all of the file associations I've tried (including ini, Properties, and TOML) indicate an error because there are no quotes around google.
I want to know if there is an easy way to open a .txt file and load some comma delimited data into variables in Scratch and furthermore add some variable data from Scratch to a .txt file or similar?
I have done a fair bit of google searching but not come across anything so I thought I would ask you guys.
I would love to use Java or something but its for my school kids and I cannot teach them to do it in Java or something else as they need to do what they have to in Scratch which is annoying but something I cannot change.
Scratch does not have file IO capabilities, and i doubt it ever will.
The closest thing that i know of is importing/exporting a list. Right-click on the list watcher from the Scratch IDE, and export. It will produce a .txt file, with each list item on a new line. If you have a similarly formatting TXT file, you can import it using the same method. Each line corresponds to a list item. Comma delimited data doesn't work with this.
You can download and edit the json script for the Scratch project.
From the "See Inside" screen, File->Download to your computer.
Rename the file to have a ".zip" extension instead of just ".sb2".
Unzip the file to edit the "project.json" file.
Edit the list data under "ListName": "[your list]" as desired.
Reassemble the zip file
Remove the ".zip" extension. (Back to ".sb2")
Update the Scratch project by going to the original project and selecting File->Upload from your computer.
In this sample project I have a list called "Jobs". The project.json file has a section like this...
"listName": "Jobs",
"contents": ["Accountant",
"Actor",
"Advocate",
"Appraiser",
"Architect",
"Baker",
...
Make whatever changes you want directly to the section for your list.
Currently, Scratch has no IO abilities, as the answer above me said, But there is a mechanism called JS extenions. Currently it's a closed beta, but when it will be released everyone would be able to program Javascript extensions for scratch. That means that you will be able to create a "Open file" block yourself.
EDIT: Turns out the mystery string was a simple MD5 hash of the name of the file (including the extension and capitalization).
I'm attempting to automate the process of creating a Chained MSI through InstallShield. In the GUI, this involves going to Releases, adding a chained package, linking to the MSI and streaming the file into the project.
I've reverse engineered what exactly happens behind the scenes by analyzing the project file as XML. It essentially just comes down to table edits. I understand you can use Windows Installer Automation to open an *.ism file and access the database tables (LINK).
Yet, there is a single field in the ISChainPackageData table which I cannot seem to generate or figure out how it was calculated. It is the column titled, File. It is a 32 character hex string preceded by an underscore. I have discovered that the only attribute that determines this field is the name of the MSI file being streamed. For example:
Linking to a chained MSI by the name of Test.msi, yields _29B31F67F21C9EE77CBF8C4C5D24ACE9.
Changing the name would change this. Changing the file, including replacing it with an empty file of the same name, does not.
I believe it is some kind of simple hash of the name, but I haven't had any luck guessing it.
Does anyone have any insight on what they might be using here?
Thanks!
Close. It's a hash-based GUID of a combination of a few things. I'd have to trudge up the code to find out exactly what, but it's at least the relative path and filename, and possibly something related to the package in question (probably its primary key value).
This is used to generate a unique key for each file you include with a package, without allowing duplicate files. (Windows Installer doesn't like backslashes in its primary keys.) The actual value here isn't meaningful; if you're careful to avoid duplicate keys and don't overlap file path and name combinations, you can probably put in any valid key value you like. However that may prevent the IDE from detecting duplicates itself.
how can we identify notepad files which is created in two computer, is there a any way to get any information about in which computer it was created.Or whether it is build in xp or linux.
If you right click on the file, you should be able to see the permissions and attributes of the file.
Check at the end of the line. Under GNU/Linux lines end with \n (ascii: 0x0A) while under Miscrosoft W$ndos it is \r\n (ascii: 0x0D 0x0A).

for identifying a word document but some of the info is relevant
To see on which computer the document had been created, open the Word
document in a hex editor and look for "PID_GUID". This is followed by
a globally unique identifier that, depending upon the version of Word
used, may contain the MAC address of the system on which the file was
created.
Checking the user properties (as already mentioned) is a good way to
see who the creator of the original file was...so, if the document was
not created from scratch and was instead originally created on another
system, then the user information will be for the original file.
Another way to locate the "culprit" in this case is to parse the
contents of the NTUSER.DAT files for each user on each computer. While
this sounds like a lot of work, it really isn't...b/c you're only
looking for a couple of pieces of information. Specifically, you're
interested in the MRU keys for the version of Word being used, as well
as perhaps the RecentDocs keys."
The one thing I can think on the top of my mind is inspecting the newline characters on your file - I'm assuming your files do have multiple lines. If the file was generated using Windows then a newline would be characterized by the combination of carriage return and line feed characters (CR+LF) whereas a simple line feed (LF) would be a hint that the file was generated in a Linux machine.
Right click one the file--> Details . You can see the computer name where it was created and the date.
