[RESOLVED] Conflict between borderless form manual resize and borderless form drag and move code

In the notes app I am currently developing, I have a borderless form with manual resize code and manual 'drag and move' code.
The problem is that these two conflict with each other and I can't do both of them. I can either let the form be resizable or either moveable. If you try to resize it, it doesn't work. If I remove a couple of lines of code, will work only one of the functions as I said. I attached the sample file with both functions. I tried so many times to get around the problem,nothing worked. If you'd be so kind to help me with this one, I'd really appreciate it.
Thanks in advance. Kevin

Use Karl E. Peterson's FormBdr class instead.

See if this will work for you instead. Just use a standard form and drop the code in.

Code:

---

Option Explicit

'API Calls Used To Remove The Title Bar From Window (Make A Sizeable Borderless Form)
Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" _
                            (ByVal hwnd As Long, ByVal nIndex As Long, _
                            ByVal dwNewLong As Long) As Long
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" _
                            (ByVal hwnd As Long, ByVal nIndex As Long) As Long
                           
Private Const GWL_STYLE = (-16)
Private Const WS_DLGFRAME = &H400000

'API Calls Used To Move A Form With The Mouse
Private Declare Function ReleaseCapture Lib "user32" () As Long
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" _
                            (ByVal hwnd As Long, ByVal wMsg As Long, _
                            ByVal wParam As Long, lParam As Any) As Long

Private Const HTCAPTION = 2
Private Const WM_NCLBUTTONDOWN = &HA1

Private Sub Form_Load()
    'ERASE the Title Bar
    SetWindowLong Me.hwnd, GWL_STYLE, GetWindowLong(Me.hwnd, GWL_STYLE) + &H400000
End Sub

Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    'Move the form with the Left Mouse Button
    If Button = vbLeftButton Then
        Me.MousePointer = vbSizeAll
        Call ReleaseCapture
        Call SendMessage(hwnd, WM_NCLBUTTONDOWN, HTCAPTION, 0&)
        Me.MousePointer = vbArrow
    End If
End Sub

Similar effect using different constants:

Code:

---

Option Explicit

Private Const GWL_STYLE    As Long = (-16&)
Private Const WS_CAPTION    As Long = &HC00000

Private Declare Function GetWindowLong Lib "user32.dll" Alias "GetWindowLongW" (ByVal hWnd As Long, ByVal nIndex As Long) As Long
Private Declare Function SetWindowLong Lib "user32.dll" Alias "SetWindowLongW" (ByVal hWnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long

Private Const HTCAPTION    As Long = 2
Private Const SC_MOVE      As Long = &HF010&
Private Const SC_DRAGMOVE  As Long = (SC_MOVE + HTCAPTION)
Private Const WM_SYSCOMMAND As Long = &H112

Private Declare Function SendMessage Lib "user32.dll" Alias "SendMessageW" (ByVal hWnd As Long, ByVal uMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Private Declare Sub ReleaseCapture Lib "user32.dll" ()

Private Sub Form_KeyPress(KeyAscii As Integer)
    If KeyAscii = vbKeyEscape Then Unload Me
End Sub

Private Sub Form_Load()
    KeyPreview = True
    SetWindowLong hWnd, GWL_STYLE, GetWindowLong(hWnd, GWL_STYLE) And Not WS_CAPTION
End Sub

Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    If Button = vbLeftButton Then
        MousePointer = vbSizeAll
        ReleaseCapture
        SendMessage hWnd, WM_SYSCOMMAND, SC_DRAGMOVE, 0&
        MousePointer = vbDefault
    End If
End Sub

Code above works great. But if you want to do without API calls here try this

First at design time, not run time, Set your Form ControlBox = False then simply put this in your form code

Code:

---

Option Explicit

Private LeftMouseDown As Boolean
Private StartX As Integer
Private StartY As Integer

  Private Sub Form_Load()
    Me.Caption = ""
  End Sub
 
  Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    LeftMouseDown = True
    StartX = X
    StartY = Y
  End Sub
 
  Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    If LeftMouseDown Then Me.Move Me.Left + (X - StartX), Me.Top + (Y - StartY)
  End Sub
 
  Private Sub Form_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
    LeftMouseDown = False
  End Sub
