SQL Server Integration not working in VS2022

Here is what you need to do, you need to install SSIS Project for VS 2022

To install Analysis Services, Integration Services, and Reporting Services project support, run the SSDT standalone installer or direct download from here.

The installer lists available Visual Studio instances to add SSDT tools. If Visual Studio isn't already installed, selecting Install a new SQL Server Data Tools instance installs SSDT with a minimal version of Visual Studio, but for the best experience, we recommend using SSDT with the latest version of Visual Studio

SSIS: Cannot convert between unicode and non-unicode string data types

Best thing to resolve this to add Data Conversion transformations to convert string columns from non-Unicode (DT_STR) to Unicode (DT_WSTR) strings.

You need to do this for all the string columns.


Add a data conversion task between OLEDB and EXCEL Destinations and do string conversations like below for the columns you are using

How to Kill Excel Ghost Process in SSIS using VB.NET

Here is the simple method to kill Excel Ghost process which is running behind scene while running SSIS package. Here is a small method to kill Excel process if we know the excel caption or excel title we want to close.
Code snippet of the method to kill Excel process
Private Sub KillExcellProcess(ByVal excelCaption As String)
Dim proc As System.Diagnostics.Process
For Each proc In System.Diagnostics.Process.GetProcessesByName("EXCEL")
If (proc.MainWindowTitle = excelCaption) Then
End If
End Sub

Use this method in SSIS script task to kill the Excel Ghost process by calling this method in your code
Dim xlApp As Excel.Application
Dim xlBook As Excel.WorkbookClass
xlApp = CType(CreateObject("Excel.Application"), Excel.Application)
xlApp.Visible = False
xlApp.DisplayAlerts = False
' Once done with excel stuff and when you want
' to kill excel use the below lines of code
Dim sCaption As String
sCaption = xlApp.Caption
Hope this helps!!

How to Kill specific Excel Ghost Process generated in SSIS using VB.NET

There are some scenarios where we might need to kill excel process programmatically.  Even though we use proper error handling and try catch to clear all excel objects still the excel ghost process remains in usage. So for these cases we might need to kill the excel process generated in SSIS package by identifying its process.   Here is how we can kill specific excel process by getting the process id of the excel that is been generated by SSIS package in script task. Refer to my previous blog for kill process by its name
<Runtime.InteropServices.DllImport("user32.dll")> _
Private Shared Function EndTask(ByVal hWnd As System.IntPtr) As Integer
End Function
<Runtime.InteropServices.DllImport("user32.dll")> _
Private Shared Function FindWindow(ByVal lpClassName As String, ByVal lpWindowName As String) As IntPtr
End Function
<Runtime.InteropServices.DllImport("kernel32.dll")> _
Private Shared Function SetLastError(ByVal dwErrCode As Integer) As IntPtr
End Function
<Runtime.InteropServices.DllImport("user32.dll", SetLastError:=True)> _
Private Shared Function GetWindowThreadProcessId(ByVal hWnd As System.IntPtr, ByRef lpdwProcessId As Integer) As Integer
End Function

Public Sub EnsureProcessKilled(ByVal MainWindowHandle As System.IntPtr, ByVal Caption As String)
' for Excel versions <10, this won't be set yet
If System.IntPtr.Equals(MainWindowHandle, System.IntPtr.Zero) Then
MainWindowHandle = FindWindow(Nothing, Caption)
End If
If System.IntPtr.Equals(MainWindowHandle, System.IntPtr.Zero) Then
End If
' at this point, presume the window has been closed.
Dim iRes As Integer = 0
Dim iProcID As Integer = 0
iRes = GetWindowThreadProcessId(MainWindowHandle, iProcID)
' can?t get Process ID
If iProcID = 0 Then
If EndTask(MainWindowHandle) <> 0 Then
End If
' success
Throw New ApplicationException("Failed to close.")
End If
Dim proc As System.Diagnostics.Process = Nothing
proc = System.Diagnostics.Process.GetProcessById(iProcID)
If proc.HasExited Then
End If
End Sub

Use this method in SSIS script task to kill the Excel Ghost process by calling this method in your code
Dim sVer As String
sVer = xlApp.Version
Dim iHandle As IntPtr = IntPtr.Zero
If Val(Convert.ToDouble(sVer)) >= 10.0 Then
iHandle = New IntPtr(CType(xlApp.Parent.Hwnd, Integer))
End If
'To kill process created by this job by process id
EnsureProcessKilled(iHandle, xlApp.Caption)

Hope this help!!
