How can I disable a close button on a form?

How can I disable a close button which is on upper right corner of a form as show in the attached file?

You can't directly.

Most people just trap it in the Query_Unload event handler.

I'm not familiar with Query_Unload but here is how to trap a number of close events:

Code:

---

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)

    Select Case UnloadMode
        Case vbFormControlMenu
            MsgBox "The user chose the Close command (the ""X"") from the Control menu on the form."
        Case vbFormCode
            MsgBox "The Unload statement is invoked from code."
        Case vbAppWindows
            MsgBox "The current Microsoft Windows operating environment session is ending."
        Case vbAppTaskManager
            MsgBox "The Microsoft Windows Task Manager is closing the application."
        Case vbFormMDIForm
            MsgBox "An MDI child form is closing because the MDI form is closing."
        Case vbFormOwner
            MsgBox "A form is closing because its owner is closing."
    End Select

End Sub

just add Cancel= 1 in the case statement you want to disable

Is this what you are looking for?

Edit

There is one more simpler way to do it...

Paste this in the form code

Code:

---

Private Sub Form_Load()
    Temp = DisableCloseButton(Form1) = False ' where Form1 is the name of your form
End Sub

---

and paste this in a module

Code:

---

Private Declare Function RemoveMenu Lib "user32" _
    (ByVal hMenu As Long, _
    ByVal nPosition As Long, _
    ByVal wFlags As Long) As Long
Private Const MF_BYPOSITION = &H400&

Public Function DisableCloseButton(frm As Form) As Boolean
    Dim lHndSysMenu As Long
    Dim lAns1 As Long, lAns2 As Long
    lHndSysMenu = GetSystemMenu(frm.Hwnd, 0)
    lAns1 = RemoveMenu(lHndSysMenu, 6, MF_BYPOSITION)
    lAns2 = RemoveMenu(lHndSysMenu, 5, MF_BYPOSITION)
    DisableCloseButton = (lAns1 <> 0 And lAns2 <> 0)
End Function
