标题: 如何在自己的DOS程序中取得长文件名? [打印本页]
作者: cly119 时间: 2005-11-6 22:31 标题: 如何在自己的DOS程序中取得长文件名?
编译环境:
1.Win98的DOS
2.使用BC3.1来开发
请高手指教,多谢!

我有qbasic读长文件的的原程序！
作者: qb45 时间: 2005-11-20 18:15
也不知道你们需要不？
作者: bush 时间: 2005-11-21 22:23
這是個dos問題，與開發語言無關吧？
作者: qb45 时间: 2005-11-26 11:08
虽然dos不提供长文件名的列表，但是还是有许多第三方的程序来解决这个问题，如果我们明白其中的原理以后，可以自己编程来解决

我顺便把8.3格式的相同功能的模块也发了吧,不知道大家需要不
作者: JonePeng 时间: 2005-11-26 23:37
不错！请楼主继续发8.3格式的模块吧。希望楼主发带有源程序的帖子时把源程序以“插入代码”形式发表，不然会出现那些奇怪的表情。
作者: qb45 时间: 2005-11-28 09:29
这些模块可以完成的功能
1 获得当前盘符
2 获得当前路径
3 查找文件
4 文件改名
启动请用QB/L
CurrentDrive$的用法
例: PRINT CurrentDrive$
可以显示当前的盘符
CurrentPath$
例
RINT CurrentPath$ 可以显示当前的路径
FindFirstFile% (filename$, FileAttrib%)的用法
入口中filename$是要找的文件名 FileAttrib%为要找文件的属性
在找文件以前必须设置缓冲
如果要找当前目录下有没有QB.EXE这个文件
例:
DIM SHARED FileDta$ '定义缓冲区为全局共享变量
SetFileDta '设置缓冲
IF FindFirstFile% ("QB.EXE", &hFF) THEN PRINT "找到文件"
RenFile% (OldFile$, NewFile$)的用法
OldFile$,为要改名的文件名 NewFile$为你要改名字
如果你要把当前目录下的TEST.BAS 改名为 TEST.TXT
例:
OldFile$="TEST.BAS"
NewFile$="TEST.TXT"
IF RenFile% (OldFile$, NewFile$) THEN PRINT "文件改名成功"
还可以显示当前目录下所有文件,这里就不举例了!

插入代码在哪里？？我怎么没有看到啊？？？
我以上发的代码都必须在DOS下或者是WIN98中使用，请绝对不要在xp或者是2000这样以nt为内核的系统上运行！！！
长文件名的程序我就是根据本论坛中的编程资料写的！

作者: wuliang6810 时间: 2005-12-23 16:45 标题: 感谢楼上的兄弟
我是用TC写 的程序，我希望能把自己的数据生成一个长文件名，不知道如何解决，菜鸟一个，QB很久没用了，有通过C解决的朋友说一声，谢谢！
作者: LiveOnLove 时间: 2005-12-24 15:46
是啊。用TC2写的，没有办法支持长文件名。。。晕了。
作者: qb45 时间: 2005-12-26 14:09
其实用TC2.0也完全可以的，只要你会用TC的DOS中断调用函数，一样可以做出来，不过比QBASIC稍微麻烦一些！
作者: qb45 时间: 2005-12-26 14:11
有关长文件名的中断调用资料本论坛中就有现成的！
我的代码就是根据本论坛中的编程资料写的！我也要谢谢发资料的网友！
作者: wuliang6810 时间: 2006-1-8 14:41 标题: wuliang6810
老兄：资料在在哪里啊！谢谢你。
作者: qb45 时间: 2006-1-13 22:12
你在本论坛里点搜索，然后输入＂长文件名＂
就可以找到了这个资料了！！
这个资料是网友＂lemonhall＂转发的，很好的编程资料！
请你找找看！
附：
当然，你也可以到qbasic论坛的编程资料区下载相关资料，这个编程资料区与编程语言无关，只是编程资料，例如：扩展和原始的ＩＮＴ１３中断调用资料，ＳＶＧＡ中断调用资料，长文件名与８．３文件功能相关资料等等！
是网友ＡＲＥＹＯＮＧ开的论坛！
