代码隐藏:
变量 FilePathName
的.aspx:
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server" Text="Label"></asp:TextBox>

这是Code-Behind,我的目标是在一个框架中打开.pdf文件,以便我可以在一个窗口中与另一个.htm页面一起打开:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim sFilePath As String
Dim buffer As Byte()
Using con As New SqlConnection()
con.ConnectionString = ConfigurationManager.ConnectionStrings()("SqlServerConnection").ConnectionString
con.Open()
Using cmd As New SqlCommand("SELECT imageLaw FROM Laws WHERE ID = @ID", con)
Dim pID As New SqlParameter("@ID", SqlDbType.Int)
pID.Value = CType(Request.QueryString("pID"), Integer)
cmd.Parameters.Add(pID)
buffer = cmd.ExecuteScalar()
End Using
con.Close()
End Using
sFilePath = System.IO.Path.GetTempFileName()
System.IO.File.Move(sFilePath, System.IO.Path.ChangeExtension(sFilePath, ".pdf"))
sFilePath = System.IO.Path.ChangeExtension(sFilePath, ".pdf")
System.IO.File.WriteAllBytes(sFilePath, buffer)
'Literal1.Text = "<frame src=\"" + sFilePath + " \ ">"
'TextBox1.Text = sFilePath
' ''Response.WriteFile(sFilePath)
' ''Response.End()
' ''Response.BinaryWrite(buffer)
'Dim act As Action(Of String) = New Action(Of String)(AddressOf OpenFilePW)
'act.BeginInvoke(sFilePath, Nothing, Nothing)
End Sub
Private Shared Sub OpenFilePW(ByVal sFilePath As String)
Using p As New System.Diagnostics.Process
p.StartInfo = New System.Diagnostics.ProcessStartInfo(sFilePath)
p.Start()
p.WaitForExit()
Try
System.IO.File.Delete(sFilePath)
Catch
End Try
End Using
End Sub
我正在评论最后一行,因为我不希望在网页外打开.pdf文件。

您可以使用asp:Literal作为框架HTML的容器,或使用&lt;%= Variable%&gt;标签... 解决方案1:
<frameset cols="100%,*">
<asp:Literal ID="litFrame" runat="server"></asp:Literal>
</frameset>
and in CB : litFrame.Text = "<frame name=\"main\" target=\"main\" src=\"" + FilePathName + "\">";
解决方案2: 在ASPX中:
<frameset cols="100%,*">
<frame name="main" target="main" src="<%= myTarget %>">";
</frameset>
PS:超过10年以来,网页已被弃用......
