什么不对这个代码:E_OUTOFMEMORY,堆损坏
HRESULT AllocateAndFillOutParameters(DWORD * a_Attrib_Count, BSTR ** a_AttribName, DWORD** a_AttribId,BSTR** a_AttribDescription, BSTR** a_AttribDataType,
BSTR** a_AttribAdvanceDataType,DWORD** a_attribfieldlength, VECTOROFATTRIBUTESSTRUCT a_vectAttributes)
{
HRESULT hr = S_OK;
VECTOROFATTRIBUTESSTRUCT::iterator itr_vectCategory = a_vectAttributes.begin();
// Memory Allocation
*a_Attrib_Count = a_vectAttributes.size();
*a_AttribName = (BSTR*)CoTaskMemAlloc(*a_Attrib_Count * sizeof(BSTR));
*a_AttribDescription = (BSTR*)CoTaskMemAlloc(*a_Attrib_Count * sizeof(BSTR));
*a_AttribId = (DWORD*)CoTaskMemAlloc(*a_Attrib_Count * sizeof(DWORD));
*a_AttribDataType = (BSTR*)CoTaskMemAlloc(*a_Attrib_Count * sizeof(BSTR));
*a_AttribAdvanceDataType = (BSTR*)CoTaskMemAlloc(*a_Attrib_Count * sizeof(BSTR));
*a_attribfieldlength = (DWORD*)CoTaskMemAlloc(*a_Attrib_Count * sizeof(DWORD));
//
for(int i=0 ;itr_vectCategory != a_vectAttributes.end(); itr_vectCategory++, i++)
{
*((*a_AttribName)+i) = SysAllocString(itr_vectCategory->m_strAttributeName.c_str());
*((*a_AttribId)+i) = itr_vectCategory->m_dwAttributeId;
*((*a_AttribDescription)+i) = SysAllocString(itr_vectCategory->m_strAttributeDescription.c_str());
*((*a_AttribDataType)+i) = SysAllocString(itr_vectCategory->m_strAttributeDataType.c_str());
*((*a_AttribAdvanceDataType)+i) = SysAllocString(itr_vectCategory->m_strAttributeAdvanceDataType.c_str());
*((*a_attribfieldlength)+i) = (itr_vectCategory->m_dwAttributeFieldLength);
}
return hr;
}
它给堆损坏的运行时异常,我是在分配错误的方式? 感谢您的帮助。
这是生产守则吗? – 2012-01-11 13:57:01
在循环中,它应该真的是'(* a_AttribName)+ 1'吗?你不应该加'i'而不是'1'吗? – 2012-01-11 14:01:09
是的,这是我在这里输入错误。 – Ehsank 2012-01-11 14:02:48
