我是WTL的新手 这是我主要对话框的onCreate代码
int Cwin32_mfcDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CDialogEx::OnCreate(lpCreateStruct) == -1)
return -1;
// TODO: Add your specialized creation code here
MARGINS mar = {0};
mar.cyBottomHeight = 100;
DwmExtendFrameIntoClientArea(m_hWnd,&mar);
return 0;
}
但是当我尝试编译我的项目时，我得到了这个错误
error LNK2019: unresolved external symbol __imp__DwmExtendFrameIntoClientArea@8 referenced in function "public: int __thiscall Cwin32_mfcDlg::OnCreate(struct tagCREATESTRUCTA *)" (?OnCreate@Cwin32_mfcDlg@@QAEHPAUtagCREATESTRUCTA@@@Z)
这是输出：
