This method converts an expression string to a parsed expression.

Syntax

HRESULT Parse(   
   LPCOLESTR                upstrExpression,  
   PARSEFLAGS               dwFlags,  
   UINT                     nRadix,  
   BSTR*                    pbstrError,  
   UINT*                    pichError,  
   IDebugParsedExpression** ppParsedExpression  
);  

int Parse(  
   string                     upstrExpression,   
   enum_PARSEFLAGS            dwFlags,   
   uint                       nRadix,   
   out string                 pbstrError,   
   out uint                   pichError,   
   out IDebugParsedExpression ppParsedExpression  
);

Parameters

upstrExpression
[in] The expression string to be parsed.

dwFlags
[in] A collection of PARSEFLAGS constants that determine how the expression is to be parsed.

nRadix
[in] Radix to be used to interpret any numerical information.

pbstrError
[out] Returns the error as human-readable text.

pichError
[out] Returns the character position of the start of the error in the expression string.

ppParsedExpression
[out] Returns the parsed expression in an IDebugParsedExpression object.

Return Value

If successful, returns S_OK; otherwise, returns an error code.

Remarks

This method produces a parsed expression, not an actual value. A parsed expression is ready to be evaluated, that is, converted to a value.
