ASP+上载例子| 中国建站之家

  下面是用ASP+来纺写的上载例子！！在ASP中我们就才上载有许多组件:

  <html>

  <script language="VB" runat=server>
  'VB代码
  Sub UploadBtn_Click(Sender as Object, E as EventArgs)
  '以http://www.aspcool.com/lanmu/test.jpg上载为例
  UploadFile.PostedFile.SaveAs(Server.MapPath("http://www.aspcool.com/lanmu/test.jpg"))

  MyImage.ImageUrl = "http://www.aspcool.com/lanmu/test.jpg"

  MyImage.Visible = true

  End Sub

  </script>

  <body>

  <form enctype="multipart/form-data" runat=server>

  <h3>

  选择要上载的文件:

  <input id="UploadFile" type=file runat=server name="file">

  <asp:button text="Upload Me!" onClick="UploadBtn_Click" runat=server/>

  <hr>

  <asp:image id="MyImage" visible=false runat=server/>

  </form>

  </body>

  </html>

  下面是一个更详细的例子,其可以上载文件！还用了 System.Drawing APIs 重新定议了图象, 同时还在图片上加上你的文字，我是用 C#编写的 -- 你也可以用VB、Jscript来写。

  <%@ Import Namespace="System.IO" %>
  <%@ Import Namespace="System.Drawing" %>
  <%@ Import Namespace="System.Drawing.Imaging" %>

  <html>

  <script language="C#" runat=server>

  void UploadBtn_Click(Object sender, EventArgs e)
  {
  UploadFile.PostedFile.SaveAs(Server.MapPath("http://www.aspcool.com/lanmu/test.jpg"));
  ImageEditor.Visible = true;
  }

  void UpdateBtn_Click(Object sender, EventArgs e)
  {
  System.Drawing.Image image = System.Drawing.Image.FromFile(Server.MapPath("http://www.aspcool.com/lanmu/test.jpg"));
  System.Drawing.Image newimage = new Bitmap(image.Width, image.Height, PixelFormat.Format32bppRGB);
  Graphics g = Graphics.FromImage(newimage);
  g.DrawImage(image,0,0,image.Width,image.Height);
  Font f = new Font("Lucida Sans Unicode", Int32.Parse(FontSize.SelectedItem.Text));
  Brush b = new SolidBrush(Color.Red);
  g.DrawString(Caption.Text, f, b, 10, 140);
  g.Dispose();
  System.Drawing.Image thumbImage = newimage.GetThumbnailImage(Int32.Parse(Width.Text),Int32.Parse(Height.Text),null,0);
  image.Dispose();
  thumbImage.Save(Server.MapPath("http://www.aspcool.com/lanmu/test.jpg"), ImageFormat.JPEG);
  }

  </script>

  <body>

  <form enctype="multipart/form-data" runat=server>

  <h3>

  选择要上载的文件:
  <input id="UploadFile" type=file runat=server name="file2">

  <asp:button text="Upload Me!" onClick="UploadBtn_Click" runat=server/>

  <hr>
  <asp:panel id="ImageEditor" visible=false runat=server>
  <img src="http://www.aspcool.com/lanmu/test.jpg">
  <h3>
  图象的宽度: <asp:textbox id="Width" runat=server/>
  图象的高度: <asp:textbox id="Height" runat=server/>

  文字的内容: <asp:textbox id="Caption" runat=server/>
  文字的大小: <asp:dropdownlist id="FontSize" runat=server>
