vb如何截取字符串

显示全部楼层 · 2009-7-8 19:05:51

我用common dialog控件选了某个程序，比如C:\Program Files\ghost\ui\2.exe,那么我要用截取字符串的方法找出2.exe的所在文件夹的路径即C:\Program Files\ghost\ui，如何实现，有个网友给我了这样的代码：pos = InStr(reverse(FileName), "\")
可我不会用，麻烦指点下，如何把截取的路径读到变量aaa内

pos = InstrRev(FileName, "\")是取得最后一个\的位置,路径就是Private Sub Command1_Click()
FileName = "C:\Program Files\ghost\ui\2.exe"
pos = InStrRev(FileName, "\")
aaa = Left(FileName, pos - 1)
Print aaaEnd Sub...

Function GetFilePath(FileName As String, file) As String
Dim temp As String
temp = StrReverse(FileName)
pos = InStr(temp, "\")
file = StrReverse(left(temp, pos ...
