Example       Related Topics

A COM message indicates that a COM operation failed. After each COM API call, or COM interface call, Purify examines the HRESULT. If it is not S_OK, indicating the operation was successful, Purify displays a COM message.

If the problem was an interface method failure, Purify also displays the interface type (for example, IMoniker, IDataObject, ITypeInfo, etc.) and the interface group (for example, ActiveX, Automation, etc.).

COM messages are normally hidden by Purify's default error filters. To display the messages:

1.    Select an Error View.

2.    Open the Filter Manager dialog box.

3.    Select View > Global Filters.

4.    Select the Purify Default Filters group and deselect the COM filter.

5.    Click OK.
