[英]error C2440: 'initializing' : cannot convert from 'std::_A_iterator<_B>' to 'std::_A_iterator<_B>'
我在嘗試編譯Programm時在VisualStudio10中遇到了這個錯誤（從Unix轉移到Windows env）
error C2440: 'initializing' : cannot convert from 'std::_A_iterator<_B>' to 'std::_A_iterator<_B>'
它發生在以下行中：
std::map<const char*, std::string>::iterator data = db.find(dbtype);
您的databases接縫將聲明為std::map<const char*, std::string, PdoArguments::CharComparator>因此請使用std::map<const char*, std::string, PdoArguments::CharComparator>::iterator
錯誤C2440：“正在初始化”：無法從“ std :: _ Vector_iterator <_Ty，_Alloc>”轉換為“類型*”
[英]error C2440: 'initializing' : cannot convert from 'std::_Vector_iterator<_Ty,_Alloc>' to 'type *'
錯誤C2440：“類型轉換”：無法從“ std :: _ Vector_iterator <_Ty，_Alloc>”轉換為“ DWORD”
[英]error C2440: 'type cast' : cannot convert from 'std::_Vector_iterator<_Ty,_Alloc>' to 'DWORD'
C ++ C2440錯誤，無法從“ std :: _ String_iterator <_Elem，_Traits，_Alloc>”轉換為“ LPCTSTR”
[英]C++ C2440 Error, cannot convert from 'std::_String_iterator<_Elem,_Traits,_Alloc>' to 'LPCTSTR'
錯誤C2440：'初始化'：無法從'初始化列表'轉換為'std :: vector <char *,std::allocator<_Ty> >”
[英]error C2440: 'initializing': cannot convert from 'initializer list' to 'std::vector<char *,std::allocator<_Ty>>'
錯誤C2440：“ =”：無法從“ std :: list”轉換 <std::string,std::allocator<_Ty> > *'到'std :: string *'
[英]error C2440: '=': cannot convert from 'std::list<std::string,std::allocator<_Ty>> *'to 'std::string*'
const 轉發參考給出錯誤 C2440：'initializing': cannot convert from 'const std::string' to 'const std::string &&'
[英]const forwarding reference gives error C2440: 'initializing': cannot convert from 'const std::string' to 'const std::string &&'
C ++類型轉換：錯誤C2440：“正在初始化”：無法從“ HRESULT”轉換為“ std :: basic_string <_Elem，_Traits，_Alloc>”
[英]c++ type conversion: error C2440: 'initializing' : cannot convert from 'HRESULT' to 'std::basic_string<_Elem,_Traits,_Alloc>'
錯誤C2440：'='：無法從'std :: string []'轉換為'std :: string []'
[英]error C2440: '=' : cannot convert from 'std::string []' to 'std::string []'
錯誤C2440：“正在初始化”：無法從“ LPVOID”轉換為“ UINT”
[英]error C2440: 'initializing' : cannot convert from 'LPVOID' to 'UINT
