1、vb 读取 txt 文件1.怎么通过代码创建一个文本文件，并读取，更新内容以上为随即方式打开的文本文件dim gfilenum as integer gfilenum=FreeFile Open 文件路径及文件名 For Random As gfilenum len=3 以随即方式打开一文件如果文件不存在就新建用 get#gfilenum,记录在文件中位置,要放取得的数据的变量读取操作用 put#gfilenum,记录在文件中位置,要放着要写入数据的变量写操作close#filenum关闭文件以下为顺序方式打开的文件dim gfilenum as integer gfilenum=Free

2、File Open 文件路径及文件名 For output As gfilenum 以写入方式打开文本print#gfilenum,要写入的文本write#filenum,要写入的文本dim gfilenum as integer gfilenum=FreeFile Open 文件路径及文件名 For input As gfilenum 以读出方式打开文本input#gfilenum,用来放读取的内容的内存变量名还可用 line input#,input()等读取更详细的查msdn 2.VB 读取文本文件时，调用TextStream 对象中使用 OpenTextFile 报错了。如果是Set

3、f=fs.OpenTextFile(E:tabletrace.txt,forreading,True,TristateUseDefault)出现错误：Run-time error 5:Invalid procedure call or argument 如果是Set f=fs.OpenTextFile(E:tabletrace.txt)则不会报错。用文件对象啊 FileSystemControl操作就好了啊再加上一个 TextStream 读取文件第一行就好了啊。3.VB 通过 FileSystemObject,可以读取文本文件(.txt)。对于.bat 文件，VB可否直接读取?bat 也属于
