The latest version of this topic can be found at CUserToolsManager Class.

Maintains the collection of CUserTool Class objects in an application. A user tool is a menu item that runs an external application. The CUserToolsManager object enables the user or developer to add new user tools to the application. It supports the execution of the commands associated with user tools, and it also saves information about user tools in the Windows registry.

Remarks

To incorporate user tools into your application, you must:

  1. Reserve a menu item and an associated command ID for a user tool menu entry.

  2. Reserve a sequential command ID for each user tool that a user can define in your application.

  3. Call the CWinAppEx::EnableUserTools method and supply the following parameters: menu command ID, first user tool command ID, and last user tool command ID.

There should be only one global CUserToolsManager object per application.

For an example of user tools, see the VisualStudioDemo sample project.

Example

The following example demonstrates how to retrieve a reference to a CUserToolsManager object and how to create new user tools. This code snippet is part of the Visual Studio Demo sample.

 CUserToolsManager* pUserToolsManager = theApp.GetUserToolsManager();
    if (pUserToolsManager != NULL && pUserToolsManager->GetUserTools().IsEmpty())
    {
        // CUserToolsManager* pUserToolsManager
        CUserTool* pTool1 = pUserToolsManager->CreateNewTool();
        pTool1->m_strLabel = _T("&Notepad");
        pTool1->SetCommand(_T("notepad.exe"));

        CUserTool* pTool2 = pUserToolsManager->CreateNewTool();
        pTool2->m_strLabel = _T("Paint &Brush");
        pTool2->SetCommand(_T("mspaint.exe"));

        CUserTool* pTool3 = pUserToolsManager->CreateNewTool();
        pTool3->m_strLabel = _T("&Windows Explorer");
        pTool3->SetCommand(_T("explorer.exe"));

        CUserTool* pTool4 = pUserToolsManager->CreateNewTool();
        pTool4->m_strLabel = _T("Microsoft On-&Line");
        pTool4->SetCommand(_T("https://www.microsoft.com"));
    }

CUserToolsManager::CreateNewTool

Creates a new user tool.

CUserTool* CreateNewTool();

Return Value

A pointer to the newly created user tool, or NULL if the number of user tools has exceeded the maximum. The returned type is the same as the type that is passed to CWinAppEx::EnableUserTools as the pToolRTC parameter.

Remarks

This method finds the first available menu command ID in the range that is supplied in the call to CWinAppEx::EnableUserTools and assigns the user tool this ID.

The method fails if the number of tools has reached the maximum. This occurs when all command IDs within the range are assigned to user tools. You can retrieve the maximum number of tools by calling CUserToolsManager::GetMaxTools. You can get access to the tools list by calling the CUserToolsManager::GetUserTools method.

CUserToolsManager::CUserToolsManager

Constructs a CUserToolsManager. Each application must have at most one user tools manager.

CUserToolsManager();

 
CUserToolsManager(
    const UINT uiCmdToolsDummy,  
    const UINT uiCmdFirst,  
    const UINT uiCmdLast,  
    CRuntimeClass* pToolRTC=RUNTIME_CLASS(CUserTool),  
    UINT uArgMenuID=0,  
    UINT uInitDirMenuID=0);

Parameters

[in] uiCmdToolsDummy
An unsigned integer that the framework uses as a placeholder for the command ID of the user tools menu.

[in] uiCmdFirst
The command ID for the first user tool command.

[in] uiCmdLast
The command ID for the last user tool command.

[in] pToolRTC
The class that CUserToolsManager::CreateNewTool creates. By using this class, you can use a derived type of CUserTool Class instead of the default implementation.

[in] uArgMenuID
The menu resource ID of the arguments popup menu.

[in] uInitDirMenuID
The menu resource ID of the initial directory popup menu.

Remarks

Do not call this constructor. Instead, call CWinAppEx::EnableUserTools to enable user tools, and call CWinAppEx::GetUserToolsManager to obtain a pointer to the CUserToolsManager. For more information, see User-defined Tools.

CUserToolsManager::FindTool

Returns the pointer to the CUserTool Class object that is associated with a specified command ID.

CUserTool* FindTool(UINT uiCmdId) const;

Parameters

[in] uiCmdId
A menu command identifier.

Return Value

A pointer to a CUserTool Class or CUserTool-derived object if success; otherwise NULL.

Remarks

When FindTool is successful, the returned type is the same as the type of the pToolRTC parameter to CWinAppEx::EnableUserTools.

CUserToolsManager::GetArgumentsMenuID

Returns the resource ID that is associated with the Arguments menu on the Tools tab of the Customize dialog box.

UINT GetArgumentsMenuID() const;

Return Value

The identifier of a menu resource.

Remarks

The uArgMenuID parameter of CWinAppEx::EnableUserTools specifies the ID of the resource.

CUserToolsManager::GetDefExt

Returns the default extension that the File Open dialog box ( CFileDialog) uses in the Command field on the Tools tab of the Customize dialog box.

const CString& GetDefExt() const;

Return Value

A reference to the CString object that contains the extension.

CUserToolsManager::GetFilter

Returns the file filter that the File Open dialog box ( CFileDialog Class) uses in the Command field on the Tools tab of the Customize dialog box.

const CString& GetFilter() const;

Return Value

A reference to the CString object that contains the filter.

CUserToolsManager::GetInitialDirMenuID

Returns the resource ID that is associated with the Initial directory menu on the Tools tab of the Customize dialog box.

UINT GetInitialDirMenuID() const;

Return Value

A menu resource identifier.

Remarks

The returned ID is specified in the uInitDirMenuID parameter of CWinAppEx::EnableUserTools.

CUserToolsManager::GetMaxTools

Returns the maximum number of user tools that can be allocated in the application.

int GetMaxTools() const;

Return Value

The maximum number of user tools that can be allocated.

Remarks

Call this method to retrieve the maximum number of tools that can be allocated in the application. This number is the number of IDs in the range from the uiCmdFirst through the uiCmdLast parameters that you pass to CWinAppEx::EnableUserTools.

CUserToolsManager::GetToolsEntryCmd

Returns the command ID of the menu item placeholder for user tools.

UINT GetToolsEntryCmd() const;

Return Value

The command ID of the placeholder.

Remarks

To enable user tools, you call CWinAppEx::EnableUserTools. The uiCmdToolsDummy parameter specifies the command ID of the tools entry command. This method returns the tools entry command ID. Wherever that ID is used in a menu, it is replaced by the list of user tools when the menu appears.

CUserToolsManager::GetUserTools

Returns a reference to the list of user tools.

const CObList& GetUserTools() const;

Return Value

A const reference to a CObList Class object that contains a list of user tools.

Remarks

Call this method to retrieve a list of user tools that the CUserToolsManager object maintains. Each user tool is represented by an object of type CUserTool Class or a type derived from CUserTool. The type is specified by the pToolRTC parameter when you call CWinAppEx::EnableUserTools to enable user tools.

CUserToolsManager::InvokeTool

Executes an application associated with the user tool that has a specified command ID.

BOOL InvokeTool(UINT uiCmdId);
