Parameters

pBuffer: IVsTextBuffer

[in] An IVsTextBuffer containing the text to examine.

iLine: Int32

[in] Line to examine.

iCol: Int32

[in] Column to examine.

dwFlag: UInt32

[in] A value from the COMMONLANGUAGEBLOCK enumeration specifying which common block to look for.

pfInBlock: Int32

Returns

Int32

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

Remarks

COM Signature

From textmgr.idl:

HRESULT IVsLanguageDebugInfo2::QueryCommonLanguageBlock(  
   [in] IVsTextBuffer *pBuffer,  
   [in] long iLine,  
   [in] long iCol,  
   [in] DWORD dwFlag,  
   [out] BOOL *pfInBlock  
);

An exception handler common block is based on the language implemented by the language service but typically includes a try block and a catch block. Some languages support an additional block that is executed regardless of whether an exception occurred; for example, C# has the finally block.
