关于文件问题

[mili2003]

有很多软件（大多是游戏），可以将很多声音文件、图片文件放到一个大的文件中，用的时候从这个大文件中读取，请问在vb中怎样办？？？？/

如下方法保存:(将下面得代码拷入一个*.TXT文档,保存为*.Frm)
VERSION 5.00
Begin VB.Form Form1
Caption = "Form1"
ClientHeight = 6795
ClientLeft = 60
ClientTop = 450
ClientWidth = 8175
LinkTopic = "Form1"
ScaleHeight = 6795
ScaleWidth = 8175
StartUpPosition = 3 '窗口缺省
Begin VB.TextBox Text1
Height = 435
Left = 1680
TabIndex = 4
Text = "要保存得文字"
Top = 4560
Width = 4095
End
Begin VB.PictureBox Picture1
Height = 4350
Left = 1680
Picture = "Form1.frx":0000
ScaleHeight = 4290
ScaleWidth = 4050
TabIndex = 3
ToolTipText = "要保存得图片"
Top = 120
Width = 4110
End
Begin VB.CommandButton Command3
Caption = "读取"
Height = 555
Left = 120
TabIndex = 2
Top = 1440
Width = 1455
End
Begin VB.CommandButton Command2
Caption = "清空"
Height = 555
Left = 120
TabIndex = 1
Top = 780
Width = 1455
End
Begin VB.CommandButton Command1

Height = 555
Left = 120
TabIndex = 0
Top = 120

用资源文件,编译到资源文件里就行了~~

str="c:/aa.txt"
lngtmp=freefile()
dim byt() as byte
dim lngsize as long
open str for binary access read as #lngtmp
lngsize=lof(1)
redim byt(lngszie) as byte
put #lngtmp,,byt
close #lngtmp
那byt中存的就是文件信息,不过是二进制的
如果要不是二进制的可以这样
dim strfile as string
lngtmp=freefile()
open str for binary access read as #lngtmp
strfile=cstr(input(lof(lngtmp),lngtmp))
close #lngtmp
这样strfile中存的就是该文件的信息
