Private Declare Sub outputbdy Lib & APP.Path & "\dlltest.dll" ()
采用相对路径

以下是引用PcrazyC在2007-1-10 14:40:46的发言：
Private Declare Sub outputbdy Lib & APP.Path & "\bin\dlltest.dll" ()
再加一点,没看清楚!

以下是引用清澂居士在2007-1-10 14:37:03的发言：
Private Declare Sub outputbdy Lib "DLL路徑\dlltest.dll" ()

以下是引用PcrazyC在2007-1-10 14:51:12的发言：

DLL路徑就是DLL文件的完整路径

以下是引用清澂居士在2007-1-10 14:53:50的发言：

可以在运行时用App.Path得到绝对路径，然后用LoadLibrary

Private Declare Function FreeLibrary Lib "kernel32" (ByVal hLibModule As Long) As Long
Private Declare Function LoadLibrary Lib "kernel32" Alias "LoadLibraryA" (ByVal lpLibFileName As String) As Long
Private Declare Function GetProcAddress Lib "kernel32"(ByVal hModule As Long, ByVal lpProcName As String) As Long
Private Declare Function CallWindowProc Lib "user32" Alias "CallWindowProcA" (ByVal lpPrevWndFunc As Long, ByVal hWnd As Long,ByVal Msg As Any, ByVal wParam As Any, ByVal lParam As Any) As Long

Private Sub Form_Load()
On Error Resume Next
Dim lb As Long,pa As Long
lb =LoadLibrary("user32")
pa =GetProcAddress(lb,"SetWindowTextA")
CallWindowProc pa,Me.hWnd,"Hello !",ByVal 0&,ByVal 0&
FreeLibrary lb
End Sub
