VC编的DLL,在W7,W2003中可以被PB调用,但在W2008R2中就不行,求高手解惑

//TODO: 如果此 DLL 相对于 MFC DLL 是动态链接的，
// 则从此 DLL 导出的任何调入
// MFC 的函数必须将 AFX_MANAGE_STATE 宏添加到
// 该函数的最前面。
//
// 例如:
//
// extern "C" BOOL PASCAL EXPORT ExportedFunction()
// {
// AFX_MANAGE_STATE(AfxGetStaticModuleState());
// // 此处为普通函数体
// }
//
// 此宏先于任何 MFC 调用
// 出现在每个函数中十分重要。这意味着
// 它必须作为函数中的第一个语句
// 出现，甚至先于所有对象变量声明，
// 这是因为它们的构造函数可能生成 MFC
// DLL 调用。
//
// 有关其他详细信息，
// 请参阅 MFC 技术说明 33 和 58。
