  1. Cum pot obtine adresa curenta de la IE sau Netscape Navigator ?
    Pun un textbox (DDEText) apoi scriu:
    
    strApplication = "IEXPLORE" ' Pentru Internet Explorer 
    strApplication = "NETSCAPE" ' Pentru Netscape
    strDDETopic = strApplication & "|WWW_GetWindowInfo"
    With DDEText
    .LinkTopic = strDDETopic
    .LinkItem = "0xFFFFFFFF"
    .LinkMode = 2
    .LinkRequest
    End With
    sCurrentURL = Mid(DDEText.Text, 2, InStr(DDEText.Text, ",") - 3)
    
  2. Cum lansez browserul Internet implicit cu o anumita adresa ?
    
    Private Declare Function ShellExecute Lib "shell32.dll" _
    Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, 
    ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, _
    ByVal nShowCmd As Long) As Long 
    

    Const SW_MAXIMIZE = 3

    Private Sub Command1_Click() Dim lRet As Long lRet = ShellExecute(Me.hwnd, "open","http://www.geocities.com/siliconvalley/hills/4377", _ vbNullString, vbNullString, SW_MAXIMIZE) End Sub

  3. Rezolutia ecranului
    
    Public Function GetScreenResolution() As String
    Dim TWidth As Long
    Dim THeight As Long
    

    TWidth = Screen.Width \ Screen.TwipsPerPixelX THeight = Screen.Height \ Screen.TwipsPerPixelY GetScreenResolution = TWidth & "x" & THeight End Function

  4. Cum lansez dialogul 'Find File' ?
    Pun un label chiar invizibil pe ecran (lbl_DDE), apoi:
    
    With lbl_DDE
    .LinkTopic = "Folders|AppProperties"
    .LinkMode = vbLinkManual
    .LinkExecute "[OpenFindFile(,)]"
    End With
    
  5. Apelare 'Help' din meniu propriu
    
    Declare Function WinHelp Lib "user32" Alias "WinHelpA" (ByVal hwnd As Long,
    ByVal lpHelpFile As String, ByVal wCommand As Long, ByVal dwData As Long) As
    Long
    

    Public Const HELP_CONTEXT = &H1 ' Display topic in ulTopic Public Const HELP_HELPONHELP = &H4 ' Display help on using help Public Const HELP_INDEX = &H3 ' Display index Public Const HELP_QUIT = &H2 ' Terminate help Public Const HELP_SETINDEX = &H5 ' Set current Index for multi index help Public Const HELP_MULTIKEY = &H201& Public Const HELP_PARTIALKEY = &H105&

    Private Sub MnuHelpContents_Click() Dim Help_path As String Dim RV As Long Help_path = App.HelpFile RV = WinHelp(Me.hwnd, Help_path, &H3, CLng(0)) End Sub

  6. Dezactivarea butonului de inchidere a ferestrei ('X')
    
    Public Sub DisableCloseButton(frm as Form)
    Dim hMenu As Long
    Dim menuItemCount As Long
    hMenu = GetSystemMenu(frm.hWnd, 0)
    If hMenu Then 
    menuItemCount = GetMenuItemCount(hMenu)
    'este pe ultima pozitie (menuItemCount-1) 
    RemoveMenu hMenu, menuItemCount - 1, MF_REMOVE Or MF_BYPOSITION 
    'Sterg separatorul de linie
    RemoveMenu hMenu, menuItemCount - 2, MF_REMOVE Or MF_BYPOSITION
    DrawMenuBar frm.hWnd
    End If
    End Sub

    Public Sub TopMost(ByVal sformname As Form)
    'this function keeps the form at the top
    'not good when the argument ( sfomrname) is an mdichild already.
