IDiaSymbol::get_value

  • Article

Retrieves the value of a constant.

Syntax

HRESULT get_value (
    VARIANT* pRetVal
);

Parameters

pRetVal

[in, out] A VARIANT object that is filled in with the value of a constant.

Return Value

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

Note

A return value of S_FALSE means the property is not available for the symbol.

Remarks

The supplied VARIANT must be initialized before it is passed to this method. For more information, see the example.

Example

void ProcessValue(IDiaSymbol *pSymbol)
{
    VARIANT value;
    value.vt = VT_EMPTY;    // Initialize variant for use.
    if (pSymbol->get_value(&value) == S_OK)
    {
        // Do something with value.
    }
}

//----------------------------------------------------
// Alternate approach
void ProcessValue2(IDiaSymbol *pSymbol)
{
    CComVariant value;
    if (pSymbol->get_value(&value) == S_OK)
    {
        // Do something with value
    }
}
