unload form: only knowing handle

Hi all,

I have a question that is likely a bit unusual: I use a given tabcontrol. I create tabs on it dynamically. A tab can host a form by its handle, so I can set an OLE_HANDLE on each of the tabs to host a form.

Now, if I close the tab, the form still keeps on living in the background, while I want to unload this form.

The question: is it possible to unload a form, only knowing its OLE_HANDLE?

Thanx in advance for the answer,

Are the forms form same project ? Why you aren't trying, Unload FormName ?

If they are outside windows, how 'bout sending them WM_CLOSE message ?

VB Code:

Option Explicit
 
Private Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" ( _
     ByVal hwnd As Long, _
     ByVal wMsg As Long, _
     ByVal wParam As Long, _
     ByRef lParam As Any) As Long
 
Private Const WM_CLOSE As Long = &H10
 
Private Sub Command1_Click()
    SendMessage Form2.hwnd, WM_CLOSE, 0, 0
End Sub

... or use CloseWindows():

VB Code:

Option Explicit
 
Private Declare Function CloseWindow Lib "user32" (ByVal hwnd As Long) As Long
 
Private Sub Command1_Click()
    CloseWindow SomeHWnd 'SomeHWnd must be declared as Long
End Sub

Thanx, I'll try it... can't use unload form, because the tab control only knows the handle...
