VSCode Extension: Add document metadata when opening file - visual-studio-code

I am building an extension that will open files from a remote server, but need to add some metadata into each document opened, which I will use later when the document is saved/closed.
Is there a way I can insert metadata into each document?
vscode.workspace.openTextDocument(filePath + fileName).then(doc => {
// Add some document specific metadata
vscode.window.showTextDocument(doc);
});

I understand that VSC does that, for example storing the caret and scroll positions, or selection if any, and so on, retrieving it when you reopen the file.
I believe it does that by storing data outside of the files, otherwise it would alter their data, or it would need to manipulate metadata according to the local system (Windows, macOS, Linux, etc.), which is not obvious, if even possible.
On Windows, in C:\Users<user name>\AppData\Roaming\Code, there are a number of databases which might fit this purpose, you can do a similar thing.

When implementing a "onReferences" with visual-studio-language-server, how do I search through the content of the files in the workspace?

I'm currently implementing onReferences on the server side of a language server. When a user right clicks on some custom syntax in a markdown file, I want to be able to use that syntax to search for other occurances of strings elsewhere in the workspace.
connection.onReferences((params) => {
// I can get the syntax here from the client through params and the document manager
// but I only have access to the document manager and the open documents.
// I want to be able to return a location from a possibly unopened file elsewhere
return null;
});
Since I know this happens all the time with the ts-server (click on an interface name and find all occurances) I know this is surely possible. What general strategy am I missing that I can obtain locations of strings elsewhere?

How can I manually edit the list of recently opened files in VS Code?

I rely heavily on the File: Open Recent… command to open frequently used files, but yesterday my local Google Drive folder got moved to a new location and now I can no longer access any of the files in that folder through the Open Recent panel because the paths don't match.
The fix would be as simple as replacing "/Google Drive/" with "/Google Drive/My Drive/" but I have no idea what file contains the list of files that appears in the recently opened panel.
I'm assuming it's somewhere in ~/Library/Application Support/Code but not sure where.
I was wondering the same thing the other day and found this while searching for a solution, so I took some time to investigate it today.
It's been a a few weeks since you posted, so hopefully this will still be of help to you.
Also, I'm using Windows and I'm not familiar with macOS, but I think it should be easy enough adjust the solution.
Location of settings
Those setting are stored in the following file: %APPDATA%\Code\User\globalStorage\state.vscdb.
The file is an sqlite3 database, which is used as a key-value store.
It has a single table named ItemTable and the relevant key is history.recentlyOpenedPathsList.
The value has the following structure:
{
"entries": [
{
"folderUri": "/path/to/folder",
"label": "...",
"remoteAuthority": "..."
}
]
}
To view the current list, you can run the following command:
sqlite3.exe -readonly "%APPDATA%\Code\User\globalStorage\state.vscdb" "SELECT [value] FROM ItemTable WHERE [key] = 'history.recentlyOpenedPathsList'" | jq ".entries[].label"
Modifying the settings
Specifically, I was interested in changing the way it's displayed (the label), so I'll detail how I did that, but it should be just as easy to update the path.
Here's the Python code I used to make those edits:
import json, sqlite3
# open the db, get the value and parse it
db = sqlite3.connect('C:/Users/<username>/AppData/Roaming/Code/User/globalStorage/state.vscdb')
history_raw = db.execute("SELECT [value] FROM ItemTable WHERE [key] = 'history.recentlyOpenedPathsList'").fetchone()[0]
history = json.loads(history_raw)
# make the changes you'd like
# ...
# stringify and update
history_raw = json.dumps(history)
db.execute(f"UPDATE ItemTable SET [value] = '{history_raw}' WHERE key = 'history.recentlyOpenedPathsList'")
db.commit()
db.close()
Code references
For reference (mostly for my future self), here are the relevant source code areas.
The settings are read here.
The File->Open Recent uses those values as-is (see here).
However when using the Get Started page, the Recents area is populated here. In the Get Started, the label is presented in a slightly different way:
vscode snapshot
The folder name is the link, and the parent folder is the the text beside it.
This is done by the splitName method.
Notes
Before messing around with the settings file, it would be wise to back it up.
I'm not sure how vscode handles and caches the settings, so I think it's best to close all vscode instances before making any changes.
I haven't played around with it too much, so not sure how characters that need to be json-encoded or html-encoded will play out.
Keep in mind that there might be some state saved by other extensions, so if anything weird happens, blame it on that.
For reference, I'm using vscode 1.74.2.

Can OpenXML be used to launch a new Word instance?

I'm able to generate Word documents without issue. I save the resulting *.docx file to a temporary location and then need to launch the file in Word.
The requirement is to not "open" the file in Word (easily done with a Process.Start) but to have load into Word as a new unsaved file. This is because certain propriety integrations for Word need to take over when a user saves the file and don't kick in if the file is ready saved but to a location on disk.
I've achieved this by using Interop calls to the Word application, adding the new document to Word's workspace. My problem is with Interop which tends to break on various client machines, particularly when Office upgrades take place (say a client had 32-bit office but upgraded with a 64-bit version).
I'm somewhat new to OpenXML, but can it be used to automate Word or is Interop my only real option?
object oFilename = tmpFileName;
object oNewTemplate = false;
object oDocumentType = 0;
object oVisible = true;
Document document = _application.Documents.Add(ref oFilename, ref oNewTemplate, ref oDocumentType, ref oVisible);
No, the Open XML technology has no way of interacting with the Office (Word) application - it's for file creation/manipulation, only. The interop is required in order to do anything with the Word application.
There is sort of a way around this - and it's only possible with Word, no other Office application has this - is to convert the Open XML content to the OPC flat-file format. This "concatenates" the various packages that make up the zip file to a pure text string, essetially a single XML file.
XML content in the OPC flat-file format can then be written to an already opened (even newly created) Word document using the Range.InsertXML method via "the interop". In a way, this "streams" the Open XML content into the opened Word document.
The problem with this approach is that certain document-level properties are not written to the target document, so not all aspects of the opened document can be changed. For example: page size, orientation, headers, footers... So if this kind of thing also needs to be affected the interop is required for such settings.

Recovering data from Firebird database partially-encrypted by ransomware

our test server was hacked and they installed a ransomware (Cry36) for which there is no solution to date. We also didn't keep any snapshots up to date (lesion learned).
Since it's only a test server, i am not too worried. But we had stored in our Firebird DB (v2.5) a bunch of work which i would like to save.
Looking at the database in a hex editor, i can see that the data is encrypted up until offset 00006430.
Looking at the structure of the firebird database it says that all the headers are encrypted (Header page, PIP,..., Data page).
All the data is still there.
I've tryed with gfix and even copying the headers from an older version of the db. But while it does fix the db, the headers are wrong and most of the new pages are removed.
Does anyone have any idea how to restore the database or extract the tables?
Regards
I have used this method restoring ransomware files encrypted on hard drives from any ransomware by renaming the file in question back to its original filename and extension. You may be able to apply the same method to revert the data or database back to the pre-encrypted version of the file/s or data/bases.
From my testing:
the ransomed file = is compressed and or simply renamed, the encryption is either not applied actually but only implied or the containing file or renamed file is encrypted but the original file is never touched. Simply rename back to original and you can access the file as you could be for the attack. Example:
This is the Ransomed file:
Adobe Acrobat XI Pro 11.0.20.zip.id[42AF04FF-2275].[supportcrypt2019#cock.li].Adame
This is the Ransomed file, renamed and fixed:
Adobe Acrobat XI Pro 11.0.20.zip
The removed portion of the FileName is:
.id[42AF04FF-2275].[supportcrypt2019#cock.li].Adame
Upon renaming the file, you will be prompted for approval to change the application type/ file type for which the file will be opened (Back to its original state), and what application will open it (its original designation as determined by the FileType preset after the FileName. The reason the file doesn't work when ransomed is the final file extension renaming scheme, whereas in this case .ADAME is not a real file type, but made up, and no program will or can open it. Thus, the file can not be opened as named.
You would need to do this for each file individually, could you post more information on the database file and encryption information as this should work for you as well. The Ransom Methodology should be the same. I can not identify the naming scheme used on your system without more information pertaining to unusual or new/unidentified portions of code injected throughout your instance.
For Renaming multiple files you could try an application such as "Advanced Renamer" for bulk processing.

How to start Microsoft Word from Java FX with parameters to run a macro

I have a document management system which stores files in a MS Word format. In my application, I would like to be able to open that document in Word.
I would like Word to handle all of the file system access out of the content management system. What I need to do is the following:
1) Create a new document based off a template, and then provide information that can be parsed and placed into specific fields.
I see I can do this as follows:
Runtime.getRuntime().exec("C:/Program Files (x86)/Microsoft Office/Office15/winword.exe /ttemplate_name");
My assumption here is that the template is installed on the local drive. However I would like to provide some data so that fields could be prepopulated and I am not sure how to do that?
2) I would like to be able to run a macro to open the document directly from the content management system. I think I can run a macro as follows:
Runtime.getRuntime().exec("C:/Program Files (x86)/Microsoft Office/Office15/winword.exe /mmacro_name");
However, in this case, I would need to provide the document id from the content management system so that it can retrieve it and open it.
I am unsure what switch or parameter I can use to provide the additional data for word?
Thanks!
Word provides no command-line facility to pass arguments or data when opening or creating a document.
As long as macro code is available, the macro can read data that's stored somewhere, such as in an XML file. But the file path would need to be hard-coded or derivable from a known location (path).
You don't necessarily need to call a macro in a document (or template attached to the document). If the macro is named AutoNew or AutoOpen it will execute automatically when a document is created from the template or, respectively, when a document is opened.
