OziExplorer API

Думается, сюда тем более не полезет никто НЕ владеющий английским техническим. А потому и переводить без смысла.

(Application Programming Interface)

Its more of a controlling interface, the API provides methods for other programs to control many actions of OziExplorer.

The API uses a combination of Windows Messaging the Clipboard and Files to send and receive messages and data.

Notes

Strings being sent to OziExplorer must be placed on the clipboard.
If there is more than 1 parameter in the string then a TAB (chr 9) is used to delimit the fields.

How does it Work

When OziExplorer starts it registers a windows message number with Windows, this allows OziExplorer to receive windows messages which are specifically for it.

OziMessage:=RegisterWindowMessage(pchar('OziExplorer'));
(Delphi code)

The controlling program registers the same message as it starts

OziMessage = RegisterWindowMessage("OziExplorer")
(VB code)

It doesn't matter which program registers the name first Windows will always return the same message number.

The controlling program needs to find the OziExplorer main window

(VB code)

Dim hwnd1 As Long
hwnd1 = FindWindow("TfmMainform", vbNullString)
If hwnd1 = 0 Then
   Showmessage ("Please Start OziExplorer")
   Exit Sub
End If

To get OziExplorer to perform an action a Windows message is sent

m1 is the message number from the table above

Sub Send2Ozi(m1, m2)
  Dim hwnd1 As Long
  Dim result As Boolean
  'OziMessage is a global variable
  ' This procedure sends a message to Ozi in the
  ' windows message queue
  hwnd1 = FindWindow("TfmMainform", vbNullString)
  result = PostMessage(hwnd1, OziMessage, m1, m2)
End Sub

This is a complete action
1. Put the required parameter in the clipboard
2. Send a message to OziExplorer to perform the action

(VB code)

The parameter(s) have been placed in string s

'clear the clipboard
Clipboard.Clear
'add CRLF to the end of the string
s = s & Chr(13) & Chr(10)
'put it on the clipboard
Clipboard.SetText s
'send the message to tell OziExplorer the clipboard is ready
