Delphi“异常”处理演示程序，模拟“找不到文件”、模拟“文件格式出错”，就是在程序没有达到预期出错时应该如何处理这些异常信息，或弹出提示框，或不予理睬，一般不会不理睬，有一个合理的异常处理机制可提高程序运行稳定性。-Delphi "exception" handling demonstration program to simulate the "file not found" analog "file format error" is an error in the program did not meet expectations when information should be how to deal with these exceptions, or pop-up boxes, or ignore it, generally do not will not ignore that there is a reasonable exception handling mechanism can improve the program running stability.
