<td width="100%"><p class="style6"> asp写程序大家都知道,源代码太容易被人看到了,要是能像.NET那样生成DLL就好了,便上网去搜索,可是没有找到有用的东西,只找到了一篇《在ASP中调用基于.Net开发的 DLL》的文章,确定了.NET可以生成DLL让ASP调用.仔细研究了下,得到了结果,好了,费话不说.先做吧!<BR> 首先打开Microsoft Visual Studio .NET 2003,点击文件,再点新建项目,Visual Basic 项目中的类库,将类库命名为dujian4,再点视图中的解决方案资源管理器,将class4.vb重命名为dujian4.vb,再将dujian4.vb中的Public Class class4改为Public class dujian4,将下面的代码加在Public Class dujian4与End Class之间
<P> </P>
<P> Public Function getfilename(ByVal d)<BR> Dim datetime<BR> datetime = CStr(d)<BR> Dim date1, time1<BR> date1 = Split(d, " ")(0)<BR> time1 = Split(d, " ")(1)<BR> getfilename = Year(date1) & Month(date1) & Day(date1) & Hour(time1) & Minute(time1) & Second(time1)<BR> End Function<BR> Public Function gettimefilename(ByVal d)<BR> Dim datetime, date1<BR> datetime = CStr(d)<BR> date1 = datetime<BR> gettimefilename = Year(date1) & Month(date1) & Day(date1)<BR> End Function<BR> Public Function HTMLEncode(ByVal fString)<BR> fString = Trim(fString)<BR> fString = Replace(fString, "'", "'")<BR> fString = Replace(fString, """", """)<BR> fString = Replace(fString, "\", "\")<BR> fString = Replace(fString, "'", "'")<BR> fString = Replace(fString, "--", "--")<BR> fString = Replace(fString, vbCrLf, "<br>")<BR> fString = Replace(fString, " ", "")<BR> HTMLEncode = fString<BR> End Function</P>
<P>你可以调试中的启动来调试要封装的程序.调试成功后,我们就要生成了,点击解决方案资源管理器,右键单击dujian4点属性.在弹出的对话框中,将配置属性中的生成里面的为COM Interop 注册(R)钩上,是为了让VS.NET在编译生成时就自动注册它.设置好后点应用,确定.回到解决方案资源管理器中,对dujian4单击右键,点生成,这样你要封装的代码就生成了dujian5.dll了.再通过以下的程序调用</P>
<P><%<BR>set ofile=Server.CreateObject("dujian4.dujian4")<BR>file1=ofile.getfilename(now())<BR>set ofile=nothing<BR>%><BR><%=file1%><BR>这里只是做了一个简单的演示,调用了其中的一个生成文件名的函数!<BR>如果你要在其它的系统上调用,请参考在《ASP中调用基于.Net开发的 DLL》这篇文章<BR>用regasm dujian5.dll /tlb:dujian5.tlb /CodeBase 来注册这个DLL.<BR>希望对大家能有所帮助!<BR><a href=http://www.koyee.com target=_blank>断剑</a> <A href="http://www.koyee.com/" target=_blank>http://www.koyee.com</A></P></p>
