Good morning, I'm trying to change my old code to upload images. But it hascomplicated everything. I can not find how to adapt what I have to control radupload. Help me please.
Example
In this part of code
Public Sub subAddNewPicture(ByVal FileUploader As FileUpload, ByVal strPictureName As String, ByVal strImgFolder As String)
Dim strImageFolderPath As String
Dim strImagePath As String
Try
' Construct saving path
strImageFolderPath = Path.Combine(Request.PhysicalApplicationPath, strImgFolder)
strImagePath = Path.Combine(strImageFolderPath, strPictureName)
' Upload image this part is not as fit
FileUploader.PostedFile.SaveAs(strImagePath)
FileUploader.PostedFile.InputStream.Dispose()
FileUploader.Dispose()
Catch ex As Exception
'Throw ex
End Try
End Sub
All code here
