friends,

  I have nearly 30 bmp files to be converted to tiff files
It is possible to convert this .bmp files to tiff files only by using picconverter which i've downloaded from net.
In this case we can select more than one file at a time and convert. but for each and every files, msg box opens.
Is it possible to close the message box automaticall after getting the outputs.
 if so how.

Please give the answer quickly if you know,
        thank u,
               bye
               anu.

I had to do a similar thing for a program so created a simple app to simulate hitting the OK button. You will need to change the values marked with ****:

Option Explicit

Public Declare Function EnumWindows Lib "user32" (ByVal lpEnumFunc As Long, ByVal lParam As Long) As Long
Public Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long
Public Declare Function EnumChildWindows Lib "user32" (ByVal hWndParent As Long, ByVal lpEnumFunc As Long, ByVal lParam As Long) As Long
Public Declare Function SendNotifyMessage Lib "user32" Alias "SendNotifyMessageA" (ByVal hwnd As Long, ByVal msg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long

Public Declare Function GetDlgCtrlID Lib "user32" (ByVal hwnd As Long) As Long
Public Declare Function GetParent Lib "user32" (ByVal hwnd As Long) As Long
Public Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Public Const WM_COMMAND = &H111
Public Const BN_CLICKED = 0

Public psImportOpen As Boolean

Public Sub main()
    Dim h As Long, res As Long
    psImportOpen = True
    While psImportOpen
        psImportOpen = False
        res = EnumWindows(AddressOf EnumWindowsProc, 255)
        DoEvents
    Wend
End Sub

Public Function EnumWindowsProc(ByVal hwnd As Long, ByVal lParam As Long) As Long
    Dim res As Long, tempstr As String, temp2 As String
   
    tempstr = String$(255, 0)
    temp2 = "*** CHANGE THIS - MSGBOX WINDOW CAPTION/NAME ***"
    temp2 = temp2 & Right(tempstr, 255 - Len(temp2))
    res = GetWindowText(hwnd, tempstr, 256)
    If Left(tempstr, 14) = "*** CHANGE THIS - NAME OF WINDOW OF YOUR CONVERTER APP ****" Then
        ' This App will keep checking for msgbox
        psImportOpen = True
    End If
    If tempstr = temp2 Then
        res = EnumChildWindows(hwnd, AddressOf EnumChildProc, 255)
    End If
    EnumWindowsProc = True
End Function

Public Function EnumChildProc(ByVal hwnd As Long, ByVal lParam As Long) As Long
    Dim res As Long, tempstr As String, temp2 As String
    Dim button As Long
   
    tempstr = String$(255, 0)
    temp2 = "OK"
    temp2 = temp2 & Right(tempstr, 255 - Len(temp2))
    res = GetWindowText(hwnd, tempstr, 256)
    If tempstr = temp2 Then
        button = GetDlgCtrlID(hwnd)
        res = GetParent(hwnd)
        res = PostMessage(res, WM_COMMAND, button, BN_CLICKED * &H10000 + hwnd)
    End If
End Function
