Hey forumz,

I have an application I've built on an XP system that is not working for Windows 7 systems. When it comes to multiple operating system functionality, IM A NOOB, for now... maybe you can help me with that? yes

Alright.. after reading several posts, and searching multiple topics... I believe these can, or would be the issue with the compatibility.

Here's some code:

Possible Issue #1: (Start-Up API's, Code)

Code:
    Public Declare Function RegisterHotKey Lib "user32" (ByVal hwnd As IntPtr, ByVal id As Integer, ByVal fsModifiers As Integer, ByVal vk As Integer) As Integer

    Public Declare Function UnregisterHotKey Lib "user32" (ByVal hwnd As IntPtr, ByVal id As Integer) As Integer

    Private Declare Function FindWindowA Lib "user32" Alias "FindWindowA" (
    ByVal lpClassName As String, _
    ByVal lpWindowName As String) As IntPtr

    Private Declare Sub SetCursorPos Lib "user32" (ByVal X As Integer, ByVal Y As Integer)

    Declare Function a_a Lib "user32.dll" Alias "mouse_event" (ByVal dwFlags As Int32, ByVal dX As Int32, ByVal dY As Int32, ByVal cButtons As Int32, ByVal dwExtraInfo As Int32) As Boolean

    Private Declare Auto Function SendMessageKeyUpDown Lib "user32" Alias "SendMessage" (ByVal hwnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As IntPtr) As IntPtr
Possible Issue #2: (References)

Code:
These Are The References Used By The Application:

Reference Name: Microsoft.VisualBasic.PowerPacks.vs 
Reference Type: .NET
Version: 10.0.0.0

I Use The Rectangle Shape, And Line Shape On Some Forms
If anyone has any experience with these issues, and could help me resolve them,
it would be greatly appreciated. Please provide code if possible, Thanks.
