Vb复制文件
我找了很久都没有正确答案,望大侠们告知啊我想用VB复制一个文件到E盘.
例如:复制 "\1\1.txt" 到"E:\"源目录没有盘符.VB程序需要将子目录文件复制到E盘.VB程序在根目录下.
不知我说得清楚不` --------------------编程问答-------------------- 没看明白
app.path & "\1\1.txt" ??? --------------------编程问答-------------------- 我说的意思是..
VB程序和要被复制的文件在同一目录..
怎么不写盘符,就可以把他复制到其他盘
例如 shell "\1\1.txt" 这样 --------------------编程问答-------------------- 不写盘符…………*_*
莫非是像DOS命令一样？只知道.\代表当前目录，..\代表上一级目录，\在DOS是代表根目录，不过要先ChDrive "X:\"转到目标盘的根目录才可以用Shell "\1.exe"…………
不知道我的理解对了没？ --------------------编程问答-------------------- 不理解.... --------------------编程问答-------------------- 例如这个...
Private Sub Command1_Click()
Dim h, Sourcefile, Destinationfile As String
h = MsgBox("确定要复制吗？", vbYesNo, "询问")
If h = vbYes Then
Sourcefile = "\\system\cove.txt" '原文件位置
Destinationfile = "e:\ho\cove.txt" '目标文件位置
FileCopy Sourcefile, Destinationfile
End If
End Sub --------------------编程问答-------------------- Sourcefile = app.path & "\system\cove.txt" ?????? --------------------编程问答-------------------- app.path 即当前目录 --------------------编程问答-------------------- 楼主的意思应该是App.Path & "\1\1.txt " --------------------编程问答-------------------- 楼主的意思应该是App.Path & "\1\1.txt " --------------------编程问答-------------------- 楼主的意思应该是App.Path & "\1\1.txt " --------------------编程问答-------------------- 复制 "\1\1.txt " 到 "E:\ "源目录没有盘符.VB程序需要将子目录文件复制到E盘.
VB程序在根目录
"\1\1.txt "这个意思是 当前盘(VB程序所在盘）--根目录下的--1目录下的--1.txt
可以如下这样写：
Private Sub Form_Load()
FileCopy "\1\1.txt", "e:\1.txt"
End Sub
--------------------编程问答-------------------- 复制 "\1\1.txt " 到 "E:\ "源目录没有盘符.VB程序需要将子目录文件复制到E盘.
VB程序在根目录
"\1\1.txt "这个意思是 当前盘(VB程序所在盘）--根目录下的--1目录下的--1.txt
可以如下这样写：
Private Sub Form_Load()
FileCopy "\1\1.txt", "e:\1.txt"
End Sub
--------------------编程问答-------------------- FileCopy --------------------编程问答-------------------- 说得好晕
