Parameters

pBuffer
Type: Microsoft.VisualStudio.TextManager.Interop.IVsTextBuffer

[in] An IVsTextBuffer containing the text to examine.

iLine
Type: System.Int32

[in] Line to examine.

iCol
Type: System.Int32

[in] Column to examine.

dwFlag
Type: System.UInt32

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

pfInBlock
Type: System.Int32%

[out] Returns non-zero if iLine and iCol is inside the specified common language block; otherwise, returns zero.

Return Value

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.
