Public Function GetCurrentBlock (pTextLines As IVsTextLines, iCurrentLine As Integer, iCurrentChar As Integer, ptsBlockSpan As TextSpan(), ByRef pbstrDescription As String, ByRef pfBlockAvailable As Integer) As Integer

Parameters

pTextLines: IVsTextLines

[in] An IVsTextLines object containing the text to examine.

iCurrentLine: Int32

[in] Current line position of the cursor.

iCurrentChar: Int32

[in] Current character position of the cursor within the line.

ptsBlockSpan: TextSpan[]

[out] Specifies a span of text representing the current language block. For more information, see TextSpan.

pbstrDescription: String

[out] Returns a string containing the description of the language block.

pfBlockAvailable: Int32

[out, retval] Returns non-zero if the block is available. Otherwise, returns zero if the current cursor position does not coincide with a language block.

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 IVsLanguageBlock::GetCurrentBlock(  
   [in] IVsTextLines * pTextLines,   
   [in] LONG iCurrentLine,   
   [in] LONG iCurrentChar,   
   [out] TextSpan * ptsBlockSpan,   
   [out] BSTR * pbstrDescription  
);

Given the current position, this method returns a TextSpan structure that defines the enclosing or nearby block of text and a short description of the block.

This method is typically called from the view to populate the Find dialog box's "Search only: <current procedure>" option where <current procedure> is the pbstrDescription text. The description should be short due to limited space on the Find dialog box.

The pfBlockAvailable parameter must be set to non-zero when a block is available and zero when the position is outside any blocks. The values of the ptsBlockSpan and pbstrDescription parameters may be a null value indicating those parameters are not wanted by the caller.
