''is not a valid integer value 表示你strtoint函数使用的时候有值是'',从语法上来看看不出来的,要你自己下断点跟踪,从 g:=round(32768*(((4*strtofloat(combobox3.text))/14.7456)-3/2));这句开始下断点,一步步的走,看值,如果到Application.CreateForm(Tform5,form5);这句还没有报...
2、cells[1,1]---不是数字串;3、StrToInt(Edt1.Text)+StrToInt(StringGrid1.Cells[1,1])---整型数越界
1,400 ---含,不能转换成数值
txtSPF.text txtFF.text txtPCF.text 这三个文本框的东西 你都转换成了 float 这个错误很明显就是告诉你:不是一个有效的浮点数 你的三个文本 肯定输入了其他东西。你可以在 except 里提示让他不要输入正确这些提示。
