Type: System.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.
