IUIFramework::LoadUI method

Loads the Windows Ribbon framework UI resource, or compiled markup, file.

Syntax


HRESULT LoadUI(
  [in]  HINSTANCE instance,
  [in]  LPCWSTR resourceName
);

Parameters

instance [in]

Type: HINSTANCE

A handle to the Ribbon application instance.

resourceName [in]

Type: LPCWSTR

The name of the resource that contains the compiled, binary markup.

Note  To initialize the Ribbon successfully, a compiled Ribbon markup file must be available as a resource. This markup file is an integral component of the Ribbon framework; it specifies the controls to use and their layout.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

IUIFramework::LoadUI should be called upon initialization. This method can be called multiple times during the lifecycle of an application, for example, to show or hide a Ribbon, provided that IUIFramework::Destroy is called in between.

OnCreateUICommand and OnViewChanged are called during the execution of IUIFramework::LoadUI.

Examples

The following example demonstrates a basic framework initialization function.


//
//  FUNCTION:    InitializeFramework(HWND)
//
//  PURPOSE:    Initialize the Ribbon framework and bind a Ribbon to the application.
//
//  PARAMETERS:    
//                hWnd - Handle to the Ribbon host application window. 
//
//  COMMENTS:
//
//    In order to get a Ribbon to display, the Ribbon framework must be initialized. 
//    This involves three important steps:
//      1) Instantiate the Ribbon framework object (CLSID_UIRibbonFramework).
//      2) Pass the host HWND and IUIApplication object to the framework.
//      3) Load the binary markup compiled by the UI Command Compiler (UICC.exe).
//
//
bool InitializeFramework(HWND hWnd)
{
    // Instantiate the Ribbon framework object.
    HRESULT hr = CoCreateInstance(
        CLSID_UIRibbonFramework, 
        NULL, 
        CLSCTX_INPROC_SERVER, 
        IID_PPV_ARGS(&g_pFramework));
    if (!SUCCEEDED(hr))
    {
        return false;
    }    

    // Create the application object (IUIApplication) and call the 
    // framework Initialize method, passing the application object and the 
    // host HWND that the Ribbon will attach itself to.
    CComObject<CApplication> *pApplication = NULL;
    CComObject<CApplication>::CreateInstance(&pApplication);
    hr = pApplication->QueryInterface(&g_pApplication);
    if (!SUCCEEDED(hr))
    {
        return false;
    } 

    hr = g_pFramework->Initialize(hWnd, g_pApplication);
    if (!SUCCEEDED(hr))
    {
        return false;
    }

    // Load the binary markup.  
    // Initiate callbacks to the IUIApplication object that was 
    // provided to the framework earlier and bind command handler(s) 
    // to individual commands.
    hr = g_pFramework->LoadUI(GetModuleHandle(NULL), L"APPLICATION_RIBBON");
    if (!SUCCEEDED(hr))
    {
        return false;
    }
    return true;
}
