我想打電話給在德爾福棱鏡窗口的SendMessage函數的方法,我已經聲明的類如下:德爾福棱鏡越來越未知的標識符「的DllImport」錯誤
type
MyUtils = public static class
private
[DllImport("user32.dll", CharSet := CharSet.Auto)]
method SendMessage(hWnd:IntPtr; Msg:UInt32; wParam:IntPtr; lParam:IntPtr):IntPtr; external;
protected
public
end;
當我試圖編譯,我得到的錯誤Unknown identifier "DllImport"
我以此爲例,How to call function CreateProcess in Delphi Prism?和語法看起來一樣。有沒有需要啓用的設置,還是我有語法錯誤?
