ASP+上传文件语法
这里有一个怎样用ASP+上传文件的非常简单例子<html>
<script language="VB" runat=server>
Sub UploadBtn_Click(Sender as Object, E as EventArgs)
UploadFile.PostedFile.SaveAs(Server.MapPath("test.jpg"))
MyImage.ImageUrl = "test.jpg"
MyImage.Visible = true
End Sub
</script>
<body>
<form enctype="multipart/form-data" runat=server>
<h3>
选择上传文件: <input id="UploadFile" type=file runat=server>
<asp:button Text="Upload Me!" OnClick="UploadBtn_Click" runat=server/>
<hr>
<asp:image id="MyImage" Visible=false runat=server/>
</form>
</body>
</html>
Here is a more complex example, which enables you to upload a file, and then using the System.Drawing APIs
to resize/crop the image, overlay a custom text message onto the image, and then save it back out to disk
as a .jpg (note that this sample works with *any* browser). I've written this one in C# -- but you would
obviously be able to use VB or JScript to do it as well:
<%@ 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("test.jpg"));
ImageEditor.Visible = true;
}
void UpdateBtn_Click(Object sender, EventArgs e) {
System.Drawing.Image image = System.Drawing.Image.FromFile(Server.MapPath("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));
补充：asp教程,脚本编码
