i have a web API project to be consumed from mobile applications and i was trying to make a file upload controller. there are few resources in C# and i don't find anything useful for VB.NET.
i tried this code below converting from c# to VB.NET, but says "Move is not a member of MultiPartFileData".
Imports System
Imports System.Collections.Generic
Imports System.IO
Imports System.Linq
Imports System.Net
Imports System.Net.Http
Imports System.Threading.Tasks
Imports System.Web
Imports System.Web.Http
Namespace HelloWorld.Controller
Public Class FileUploadingController
Inherits ApiController
<HttpPost>
<Route("api/FileUploading/UploadFile")>
Public Async Function UploadFile() As Task(Of String)
Dim ctx = HttpContext.Current
Dim root = ctx.Server.MapPath("~/App_Data")
Dim provider = New MultipartFormDataStreamProvider(root)
Try
Await Request.Content.ReadAsMultipartAsync(provider)
For Each file In provider.FileData
Dim name = file.Headers.ContentDisposition.FileName
name = name.Trim(""""c)
Dim localFileName = file.LocalFileName
Dim filePath = Path.Combine(root, name)
File.Move(localFileName, filePath)
Next
Catch e As Exception
Return $"Error: {e.Message}"
End Try
Return "File uploaded!"
End Function
End Class
End Namespace
That error message means the compiler think that you are trying to call a method from the MultiPartFileData class. The variable of type MultiPartFileData is the one called file (notice the lowercase) initialized in the For Each loop.
Instead you want to call the Move method from the System.IO.File class (notice the uppercase).
VB.NET services (always running in background looking to catch errors while you type) is case insensitive so, for it, the two names are the same and here arises the error emitted when you code that line.
The best solution is to avoid names like file for your variables when you plan to use the class System.IO.File. Otherwise you could simply add the full qualified method's name in this way
System.IO.File.Move(localFileName, filePath)
I want to create a custom WebElement from IWebElement and then implement FindElement to locate an element in my internal list of elements in m_Elements:
I have this snippet so far:
Imports OpenQA.Selenium
Imports OpenQA.Selenium.By
Imports System.Collections.ObjectModel
Imports System.Drawing
Imports System.Text.RegularExpressions
Public Class MyWebElement
Implements IWebElement
Private m_Elements As New List(Of MyWebElement)
Public Function FindElement(byObj As By) As IWebElement Implements ISearchContext.FindElement
'
End Function
If I look at byObj in Visual Studio I see:
Equals, FindElement, FindElements, GetHasCode, GetType, ToString.
If I look at byObj in the debugger I see:
Description, FindElementMethod, and FindElementsMethod
How do I determine what By class was used by the caller? By.Id, By.TagName, etc.
How do I get the SearchContext?
How i can use ODP tool for oracle connection while working with VB.NET web service in the following web service in order to retrieve data from an oracle? The query that I would like to use is

Public Function GetAliquot_ID(ByVal aliquot_id As Integer) As Integer
Return (aliquot_id)

I'm getting this (Dts is not declared) exception when I try to build my SSIS script task. Any idea how to resolve it?
here is the part of my code
Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Runtime
Public Class ScriptMain
Public Sub Main()
Try
Dim cm As ConnectionManager = Dts.Connections.Add("FTP")
cm.Properties("ServerName").SetValue(cm, Dts.Variables("SFTPServerName").Value.ToString)
cm.Properties("ServerUserName").SetValue(cm, Dts.Variables("SFTPLogin").Value.ToString)
cm.Properties("ServerPassword").SetValue(cm, Dts.Variables("SFTPPassword").Value.ToString)
cm.Properties("ServerPort").SetValue(cm, Dts.Variables("SFTPPortNumber").Value.ToString)
This worked for me:
Add Your_Variable in the script component. (Right click --> Edit --> Script --> ReadOnlyVariables).
Dim variableString As String = Me.ReadOnlyVariables("User::Your_Variable").Value.ToString().
Try adding;
Imports Microsoft.SqlServer.Dts
Try me.Connections and me.Variables
I have a MVC3 application which uses Devexpress controls.
My first page works fine, but this is not strongly typed.
I get the error "BC30451: 'ViewData' is not declared. It may be inaccessible due to its protection level" on my second page which starts with:
#ModelType IEnumerable(Of MyModel.XXX)
#Code
ViewBag.Title = "Index"
End Code
<h2>Index</h2>
The resulting vb code inherits from System.Web.Mvc.WebViewPage.
Is there a problem with the imports???

I think I solved the problem:
I created the view with MvcScaffolding and the file was saved with ANSI encoding. However, there were German umlauts in my model class name and these got corrupted.
Changing the file encoding to UTF8 solved the issue...
