问题描述
Private Sub video()
If IsPostBack Then
Dim path As String = Server.MapPath("~/UploadedVideos/")
Dim fileOK As Boolean = False
If FileUpload1.HasFile Then
Dim fileExtension As String
fileExtension = System.IO.Path. _
GetExtension(FileUpload1.FileName).ToLower()
Dim allowedExtensions As String() = _
{".mov", ".wmv", ".avi", ".vob", ".mp4"}
For i As Integer = 0 To allowedExtensions.Length - 1
If fileExtension = allowedExtensions(i) Then
fileOK = True
End If
Next
If fileOK Then
Dim Conn As New SqlConnection(ConfigurationManager.ConnectionStrings("projectConnectionString").ConnectionString)
Conn.Open()
Try
Dim FilePath = path & FileUpload1.FileName
'Here you can fire your insert statement in filepath value u can pass directly that value
Dim SQL As String = "INSERT INTO EmpData ( [Video]) VALUES (@VideoUrl)"
Dim cmd As New SqlCommand(SQL, Conn)
cmd.Parameters.Add("@VideoUrl", SqlDbType.NVarChar, 50, FilePath)
FileUpload1.PostedFile.SaveAs(path & _
FileUpload1.FileName)
lblError.Text = "File uploaded!"
cmd.ExecuteNonQuery()
Conn.Close()
Catch ex As Exception
lblError.Text = "File could not be uploaded." & ex.Message
End Try
Else
lblError.Text = "Cannot accept files of this type."
End If
End If
End If
End Sub
这是我的代码，用于将视频文件上传到Webform应用程序项目中的特定文件夹，但是问题是当我从保存按钮调用该video()时，此错误在浏览器中显示:T
重置连接后，页面加载时重置了与服务器的连接.
这是保存按钮的代码，我在其中调用了video()
this was my code for the uploading a video file to a specific folder in my webform application project but the problem is when i call that video() from the save button this error show in the browser :T
he connection was reset the connection to the server was reset while the page was loading.
this is the code for my save button where i call the video()
Protected Sub Button3_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim connection As SqlConnection = Nothing
Try
Dim img As FileUpload = CType(PicUpload, FileUpload)
Dim imgByte As Byte() = Nothing
If img.HasFile AndAlso Not img.PostedFile Is Nothing Then
'To create a PostedFile
Dim File As HttpPostedFile = PicUpload.PostedFile
'Create byte Array with file len
imgByte = New Byte(File.ContentLength - 1) {}
'force the control to load data in array
File.InputStream.Read(imgByte, 0, File.ContentLength)
End If
' Insert the employee name and image into db
Dim conn As String = ConfigurationManager.ConnectionStrings("projectConnectionString").ConnectionString
connection = New SqlConnection(conn)
connection.Open()
Dim sql As String = "INSERT INTO EmpData (DateOfUpload, DescOfWork,WorkDone,ComOfEmp,Picture,EmpUsername)VALUES (@en1m,@en2m,@en3m,@en4m,@eimg,@en5m)SELECT @@IDENTITY"
Dim cmd As SqlCommand = New SqlCommand(sql, connection)
cmd.Parameters.AddWithValue("@en1m", Calendar1.SelectedDate)
cmd.Parameters.AddWithValue("@en2m", TypeOfWork.Text.Trim())
cmd.Parameters.AddWithValue("@en3m", WorkOfTheDay.Text.Trim())
cmd.Parameters.AddWithValue("@en4m", ComOfEmp.Text.Trim())
cmd.Parameters.AddWithValue("@eimg", imgByte)
cmd.Parameters.AddWithValue("@en5m", Request.QueryString("id"))
Dim id As Integer = Convert.ToInt32(cmd.ExecuteScalar())
Catch ex As Exception
MsgBox(ex.Message)
Finally
connection.Close()
End Try
Call video()
Response.Redirect("Employee.aspx?id=" + TextBox1.Text, False)
End Sub
