[InAttribute] IVsTextBuffer^ pBuffer,
[InAttribute] int iLine,
[InAttribute] int iCol,
[InAttribute] unsigned int dwFlag,
[OutAttribute] int% pfInBlock
)
function QueryCommonLanguageBlock(
pBuffer : IVsTextBuffer,

dwFlag : uint,
pfInBlock : int
) : int
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.
