Delphi Prism getting Unknown Identifier "DllImport" error
- by Robo
I'm trying to call Window's SendMessage method in Delphi Prism, I've declared the class as follow:
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;
When I tried to compile, I get the error Unknown identifier "DllImport"
I used this as an example, http://stackoverflow.com/questions/2708520/how-to-call-function-createprocess-in-delphi-prism and the syntax looks the same. Is there a setting I need to enable, or do I have a syntax error?
