Parameters

  • dwCompRole
    Type: UInt32

    [in] Role of the VSPackage object that is requesting the modal message display. For a list of valid dwCompRole values, see OLEROLE.

  • rclsidComp
    Type: Guid%

    [in] Class identifier (CLSID) of the VSPackage object requesting the message display.

  • pszTitle
    Type: String

    [in] Pointer to the message text header or null if there is no header to display.

  • pszText
    Type: String

    [in] Pointer to the main part of the message text or null if there is no text to display.

  • pszHelpFile
    Type: String

    [in] Pointer to the path to a Help file.

  • dwHelpContextID
    Type: UInt32

    [in] Specifies the Help context identifier.

  • msgbtn
    Type: Microsoft.VisualStudio.Shell.Interop.OLEMSGBUTTON

    [in] Specifies the set of buttons to appear in the message box. This parameter is similar to the uType parameter of the Win32 MessageBox function in that it uses similar values with similar semantics. For a list of valid msgbtn values, see OLEMSGBUTTON.

    Note   OLEMSGBUTTON_YESALLNOCANCEL is not supported and returns the same result as OLEMSGBUTTON_OK.

  • fSysAlert
    Type: Int32

    [in] If true, this flag causes the MB_SYSTEMMODAL flag to be set when showing the message. If false, no system flag is set during the message display.

  • pnResult
    Type: Int32%

    [out] Specifies the result of the message display. If ShowMessage succeeds, pnResult is set to one of the following menu item values returned by the dialog box:

    [1|1] Value

    [1|2] Description

    [2|1] IDABORT

    [2|2] Abort button was clicked.

    [3|1] IDCANCEL

    [3|2] Cancel button was clicked or the ESC key was pressed. If the message box does not have a Cancel button, pressing the ESC key has no effect.

    [4|1] IDIGNORE

    [4|2] Ignore button was clicked.

    [5|1] IDNO

    [5|2] No button was clicked.

    [6|1] IDOK

    [6|2] OK button was clicked.

    [7|1] IDRETRY

    [7|2] Retry button was clicked.

    [8|1] IDYES

    [8|2] Yes button was clicked.

Return Value

Type: Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From oleipc.idl:

HRESULT IOleComponentUIManager::ShowMessage(
   [in] DWORD dwCompRole,
   [in] REFCLSID rclsidComp,
   [in] LPOLESTR pszTitle,
   [in] LPOLESTR pszText,
   [in] LPOLESTR pszHelpFile,
   [in] DWORD dwHelpContextID,
   [in] OLEMSGBUTTON msgbtn,
   [in] OLEMSGDEFBUTTON msgdefbtn,
   [in] OLEMSGICON msgicon,
   [in] BOOL fSysAlert,
   [out][retval] LONG *pnResult
);

The title to the message box is composed of two strings: a message header and a message body.

The SOleComponentUIManager service notifies VSPackage objects registered with both this service and the SOleComponentManager service of the change to a modal state.

If the Warnings Off state is in effect, the SOleComponentUIManager service automatically inhibits the display of warning messages. However, if the message is informational or critical, it is always displayed even if the Warnings Off state is in effect.

Before displaying the message requested by an object acting as a subcomponent or a component control, the SOleComponentUIManager service gives the main component a chance to override any aspect of the message by calling its GetCntrMessage. The main VSPackage object can override the HelpFile, HelpContext, message text, or the message type.
