使用来自ftp的reportviewer显示图像 [英] Display image with reportviewer from ftp

问题描述

我编写了自定义代码以提供用户名和密码

I wrote custom code to supply username and password

Public Shared Function testimage(ByVal imageURL As String) As Byte()
      Dim request As System.Net.WebClient = New System.Net.WebClient()
      request.Credentials = New System.Net.NetworkCredential("Ftpuser", "1234567", "myPcname")
      Try     
            Dim img() As Byte = request.DownloadData(imageURL)
            Return img
       Catch ex As Exception
            Return Nothing
       End Try
    End Function

我也启用EnableExternalImages

Also I enable EnableExternalImages

this.reportViewer1.LocalReport.EnableExternalImages = true;

我写的表达

= Code.testimage（First（Fields！Pic_Path.Value，数据集1））

I wrote expression
=Code.testimage(First(Fields!Pic_Path.Value, "Dataset1"))

Image source = Database<br />
MiME Type = Image/Jpeg

我将Path存储在我的数据库中，如 ftp://192.168.111.1:1234/1.jpg

我在测试解决方案中测试VB代码并且工作正常所以我想到目前为止一切都很好但是毕竟图像没有显示在报告上所以可能有人告诉我我想念的是什么

我检查那些链接

所以任何建议！

I store the Path on My Database like ftp://192.168.111.1:1234/1.jpg
I test VB Code in test solution and it works fine So i guess everything so far is good but after all the Image is not displaying on the report so could some one tell me what i miss
I check those links
