各位大佬:
小弟在编程过程中遇到如此问题,百思不知如何解决,请各位大佬指教.
用明华非接触式读卡器(USB)读4442卡,其中FUNCTION中有length,但在FORM中还有一个数字键盘主要为在触摸屏上输入用(procedure TForm7.FormShow(Sender: TObject);),运行时在含有LENGTH语句中报错(missing operator or semicolom),但这估计不会是分号的问题,我将function语句删除,程序正常.估计是function中的length和程序中的length不相同,更要命的是在前几个FORM中都有类似的小键盘程序,是算是删除了本FORM中的程序,报错就到前FORM中的类似语句上(相同的报错信息),请大佬帮助解决,非常感激!
