CBasePropertyPage::Help (Windows CE 5.0)
The Help method invokes the property page help. This method implements the IPropertyPage::Help method.
HRESULT Help( LPCWSTR lpszHelpDir);
Parameters
- lpszHelpDir
Pointer to the string under the HelpDir key in the property page's CLSID information in the registry.
Return Value
Returns E_NOTIMPL.
Remarks
In the base class, the method always returns E_NOTIMPL. When the method fails, the frame calls IPropertyPage::GetPageInfo to get the name of the help file and context identifier. By default, these are NULL. To provide help, therefore, the derived class can override either the Help method or the CBasePropertyPage::GetPageInfo method.
Requirements
DirectShow applications and DirectShow filters have different include file and link library requirements.
For more information, see Setting Up the Build Environment.
OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
