StartFile()

async Task xeno_rat_server.Forms.File_manager.StartFile ( string path )

inline

Starts a file operation using the specified path.

Parameters

path	The path of the file to be operated on.

Exceptions

Exception

Thrown when the file operation fails.

Returns

A task representing the asynchronous operation.

This method initiates a file operation using the provided path . It creates a sub-sub-node using the client and sends a byte array with a type value of 3 to the node. It then sends the UTF-8 encoded bytes of the path to the node and receives a response. If the received data is null, it displays a message box indicating that the file operation start has failed and disconnects the node. If the received data's first byte is 0, it displays a message box indicating that the file could not be opened or does not exist and disconnects the node.

Parameters

path	The path of the directory to be updated in the list view.

Returns

A task representing the asynchronous operation.

This method asynchronously retrieves file information using the FileViewer.GetInfo method and updates the list view with the directories and files found at the specified path. If the file information retrieval is unsuccessful, a message box is displayed indicating the problem, and the method returns without further processing. The current directory is updated to the specified path, and the text box displaying the current directory is also updated. The list view is then updated by clearing its items, adding a parent directory item if the path is not empty, and adding items for each directory and file found in the retrieved file data.
