    Aprire un file

    Ho cercato nel forum ma non sono riuscito a trovare niente del genere. Allora avrei bisogno di fare un pulsante dentro un programma che si chiama Movicon, che è in pratica un ambiente di sviluppo basato su SaxBasic (molto simile al VB), questo pulsante vorrei aprisse un file Access. Esiste un comando semplicissimo per fare questo?
    codice:
    Sub Pulsante_Click()
    'Apri database.mdb
    End Sub
    Grazie

    purtroppo non esiste un comando che fa questo per interagire con un database hai bisogno di una connessione al db e di un recorset che interagisca coi dati in vb si usano le librerie ADO DAO e RDO non conoscendo in tuo compilatore non so se le supprta

    Non ci siamo capiti

    Non voglio aprire un database. O meglio, si il file è un database. Ma io vorrei sapere se esiste un sistema che cliccando questo pulsante, equivalesse a fare doppio clic del file dentro la cartella. Del tipo: se voglio aprire database.mdb lo apre con Access, se voglio aprire foglio.xls lo apre con Excel... capito come?
    Grazie mille

    API shellexecute
    ---
    The ShellExecute function opens or prints a specified file. The file can be an executable file or a document file.

    Requires Windows NT 3.1 or later; Requires Windows 95 or later

    DICHIARAZIONE

    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

    PARAMETRI

    · hwnd
    Specifies a parent window. This window receives any message boxes that an application produces. For example, an application may report an error by producing a message box.

    · lpOperation
    Pointer to a null-terminated string that specifies the operation to perform. The following operation strings are valid:
    “open”
    The function opens the file specified by lpFile. The file can be an executable file or a document file. The file can be a folder to open.
    “print”
    The function prints the file specified by lpFile. The file should be a document file. If the file is an executable file, the function opens the file, as if “open” had been specified.
    “explore”
    The function explores the folder specified by lpFile.

    The lpOperation parameter can be NULL. In that case, the function opens the file specified by lpFile.

    · lpFile
    Pointer to a null-terminated string that specifies the file to open or print or the folder to open or explore. The function can open an executable file or a document file. The function can print a document file.

    · lpParameters
    If lpFile specifies an executable file, lpParameters is a pointer to a null-terminated string that specifies parameters to be passed to the application.
    If lpFile specifies a document file, lpParameters should be NULL.

    · lpDirectory
    Pointer to a null-terminated string that specifies the default directory.

    · nShowCmd
    If lpFile specifies an executable file, nShowCmd specifies how the application is to be shown when it is opened. This parameter can be one of the following values:
    SW_HIDE
    Hides the window and activates another window.
    SW_MAXIMIZE
    Maximizes the specified window.
    SW_MINIMIZE
    Minimizes the specified window and activates the next top-level window in the Z order.
    SW_RESTORE
    Activates and displays the window. If the window is minimized or maximized, Windows restores it to its original size and position. An application should specify this flag when restoring a minimized window.
    SW_SHOW
    Activates the window and displays it in its current size and position.
    SW_SHOWDEFAULT
    Sets the show state based on the SW_ flag specified in the STARTUPINFO structure passed to the CreateProcess function by the program that started the application. An application should call ShowWindow with this flag to set the initial show state of its main window.
    SW_SHOWMAXIMIZED
    Activates the window and displays it as a maximized window.
    SW_SHOWMINIMIZED
    Activates the window and displays it as a minimized window.
    SW_SHOWMINNOACTIVE
    Displays the window as a minimized window. The active window remains active.
    SW_SHOWNA
    Displays the window in its current state. The active window remains active.
    SW_SHOWNOACTIVATE
    Displays a window in its most recent size and position. The active window remains active.
    SW_SHOWNORMAL
    Activates and displays a window. If the window is minimized or maximized, Windows restores it to its original size and position. An application should specify this flag when displaying the window for the first time.

    If lpFile specifies a document file, nShowCmd should be zero.

    VALORI DI RITORNO
    If the function succeeds, the return value is the instance handle of the application that was run, or the handle of a dynamic data exchange (DDE) server application.

    If the function fails, the return value is an error value that is less than or equal to 32. The following table lists these error values:
    0
    The operating system is out of memory or resources.

    ERROR_FILE_NOT_FOUND
    The specified file was not found.

    ERROR_PATH_NOT_FOUND
    The specified path was not found.

    ERROR_BAD_FORMAT
    The .EXE file is invalid (non-Win32 .EXE or error in .EXE image).

    SE_ERR_ACCESSDENIED
    The operating system denied access to the specified file.

    SE_ERR_ASSOCINCOMPLETE
    The filename association is incomplete or invalid.

    SE_ERR_DDEBUSY
    The DDE transaction could not be completed because other DDE transactions were being processed.

    SE_ERR_DDEFAIL
    The DDE transaction failed.

    SE_ERR_DDETIMEOUT
    The DDE transaction could not be completed because the request timed out.

    SE_ERR_DLLNOTFOUND
    The specified dynamic-link library was not found.

    SE_ERR_FNF
    The specified file was not found.

    SE_ERR_NOASSOC
    There is no application associated with the given filename extension.

    SE_ERR_OOM
    There was not enough memory to complete the operation.

    SE_ERR_PNF
    The specified path was not found.

    SE_ERR_SHARE
    A sharing violation occurred.

    ESEMPIO:
    codice:
    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_SHOWNORMAL = 1
    Private Sub Form_Load()
        'KPD-Team 1998
        'URL: http://www.allapi.net/
        'E-Mail: KPDTeam@Allapi.net
        'Send an E-Mail to the KPD-Team
        ShellExecute Me.hwnd, vbNullString, "mailto:KPDTeam@Allapi.net", vbNullString, "C:\", SW_SHOWNORMAL
    End Sub
