问题描述

以下在本地计算机上工作正常,但在实时服务器上不起作用





 < span class =code-keyword>受保护的 可覆盖  Sub  qrCodeImage_Changed( ByVal  sender  As  System。 Object 句柄  .OnQRCodeImageChanged 
' Dim strImageOriginal As String = strGuid.ToString()+ strImageSize
Dim id 作为 字符串 = Guid.NewGuid.ToString
Dim strImageOriginal 作为 字符串

结束 选择
ImageQrCode.Sa ve(Server.MapPath( QRImages / + strImageOriginal + id + 。png),System.Drawing.Imaging.ImageFormat.Png)

如果 Request.Cookies( < span class =code-string> overlay)。Value = < span class =code-keyword>和 Request.Cookies( overlay)。值= '' 然后
ImageButton1.ImageUrl =
Dim picBackground As Image = Image.FromFile(Server.MapPath(Request.Cookies( overlay)。值))
Dim picForeground As Image = Image.FromFile(Server.MapPath( QRImages / + strImageOriginal + id + 。png))
Dim finalimage As Image = OverlayImages(picForeground,picBackground)
picBackground.Dispose()
picForeground.Dispose()
finalimage.Save(Server .MapPath( QRImages / + strImageOriginal + id + 。png))
ImageButton1.ImageUrl = QRImages / + strImageOriginal + id + 。png
其他

1。告诉我们发生错误的行(为此你必须创建日志文件)

2.同时检查在服务器上创建的文件夹应该有权创建/保存文件


the following works fine on local machine but did not work on live server

        Select Case Request.Cookies("Tab_Name").Value.ToString
            Case "vcard"
                strImageOriginal = "Vcard_" & txt_firstname.Text & "_" & txt_lastname.Text
            Case "event"
                strImageOriginal = "EVent_" & Regex.Replace(txtEvent.Text, "[\[\]\\\^\$\.\|\?\*\+\(\)\{\}%,;><!@#&\-\+\/\:]", "").Replace("http", "").Replace("www", "").Split(" ")(0)

1. Tell us line where error occurs (for this u have to create log file)
2. Also check folder created on server should have rights to create/save files
