Parameters

• iAttribute
  Type: Int32

  [in] Index into the collection of attributes and keywords in the context or subcontext bag.

• pszName
  Type: String

  [in] Attribute name or keyword. Specify the attribute name to access a specific attribute in the context or subcontext bag. Specify keyword to access an F1 or lookup keyword.

• fIncludeChildren
  Type: Int32

  [in] If true, then the subcontext elements associated with the context bag are also returned. If true, then the subcontext is excluded.

• piPriority
  Type: Int32%

  [out] Priority of the attribute or keyword. For a list of piPriority values, see VSUSERCONTEXTPRIORITY.

• pbstrName
  Type: String%

  [out] Pointer to the specific attribute name or the value keyword, if a match is found.

• pbstrValue
  Type: String%

  [out, retval] Pointer to the specific attribute value or the keyword text, if a match is found.

Return Value

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

Remarks

COM Signature

From context.idl:

HRESULT IVsUserContext::GetAttributePri(
   [in] int iAttribute,
   [in] LPCOLESTR pszName,
   [in] BOOL fIncludeChildren,
   [out] int *piPriority,
   [out] BSTR * pbstrName,
   [out, retval] BSTR * pbstrValue
);

This method is very similar to the GetAttribute method, but additionally returns the priority of the attribute or keyword in the context or subcontext bag. There are three different ways to use the IVsUserContext.GetAttributePri method:

• Pass in nulla null reference (Nothing in Visual Basic) for the value of the pszName parameter and iterate through all of the attributes and keywords in the context or subcontext bag using the iAttribute parameter. You can determine the count of attributes and keywords using the CountAttributes method.

• Iterate through all of the attributes and keywords and pass in a specific attribute name or keyword for the value of the pszName parameter. An attribute name and value or keyword and value are returned in the pbstrName and pbstrValue parameters, respectively, only if the name you provided matched the name in the context or subcontext bag.

• Pass in a value of -1 for the iAttribute parameter and a specific attribute name or keyword for value of the pszName parameter. The first attribute or keyword that matches the name is returned.

If this method finds a match for the pszName parameter, then it returns S_OK. If the method does not find a match, then it returns E_UNEXPECTED. Thus, it is possible to set the values of the piPriority, pbstrName and pbstrValue parameters to nulla null reference (Nothing in Visual Basic) and evaluate the success or failure of the method based on the return values.

Use the GetAttrUsage method to determine whether keyword returned from the IVsUserContext.GetAttributePri method is an F1 or lookup keyword.
