===============Project1

Application.Run;
end.

[解决办法]
头大,这些都是基础的错误提示,打开金山词霸来翻译吧,根据提示自己都可以改
有些是控件没有,有些是单词写错,有些是语法写错
[解决办法]
procedure TForm1.Button5Click(Sender: TObject);
var
Loctstr:string;
begin
loctstr:=InputBox('按学号查询','请输入学号:','0');
if not ADOTable1.Locate('XH',loctstr,[loCaseInsensitive]) then

end;

这里if then后面怎么没有东西了啊？
