在vc 2008 dll內,兩個功能完全一樣,只是return是const char* 一個是long extern "C" _declspec(dllexport) const char* __stdcall ToServer(const char *str); extern "C" _declspec(dllexport) long __stdcall ToServer1(const char *str); 在vb6.0 Private Declare Function ToServer1 Lib "XXX.dll" (ByVal myXML As String) As Integer Private Declare Function ToServer Lib "XXX.dll" (ByVal myXML As String) as String ToServer(xxx) //會當掉 ToServer1(xxx) //成功不知是什麼原因希望有人可以幫忙指點一二 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 180.177.162.16
