Get the complete app path to open file in VB6

 Dim Wrd As Object
 
  Set Wrd = CreateObject("Word.Application")
  Wrd.Documents.Open "C:\temp\doc1.doc"

you can use the findexecutable API

Private Declare Function FindExecutable Lib "shell32.dll" Alias "FindExecutableA" (ByVal lpFile As String, ByVal lpDirectory As String, ByVal lpResult As String) As Long
' this will return the executable that is associated with a .doc file.
Private Sub Command1_Click()
Dim strEXE As String * 255
Call FindExecutable("C:\Temp\test.doc", "", strEXE)
MsgBox strEXE
End Sub

shell ("start"  & "c:\temp\test.doc",vbnormalfocus)
or use shellexecute api with "open" parameter.

Option Explicit
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

Private Sub Form_Load()
Dim ret As Long
ret = ShellExecute(Me.hwnd, "open", "c:\test.doc", vbNullString, vbNullString, vbNormal)
End Sub

 Dim oWord As Object
 
 Set oWord = CreateObject("Word.Application")
 oWord.Documents.Open "C:\MyDocuments\Word1.doc"
