I am trying to use SSIS to open an Excel file and refresh the data before importing the data into SQL Server. My dtsx package is failing on the line of code that tries to open the Excel file.
The code is straightforward and taken from here.
This is the code I am using:
public void Main()
{
// TODO: Add your code here
Dts.TaskResult = (int)ScriptResults.Success;
Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook wb;
wb = excel.Workbooks.Open(#"C:\Test.xlsx",0, false, null, null, null, true, null, null, null, null, null, null, null, null);
//wb.RefreshAll();
//wb.Save();
//wb.Close(null, null, null);
excel.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(excel);
}
The error message is as follows:
Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x800A03EC): Exception from HRESULT: 0x800A03EC

I am currently working on my test machine with the following configuration:
Visual Studio 2008 BIDS
Office 2010
Office 2010 PIAs
Does anyone have any suggestions as to how to get this working?
Use Type.Missing in place of null. And also ref before each variable. See http://msdn.microsoft.com/en-us/library/system.type.missing(v=VS.90).aspx

I am trying to enumerate the different mail items in an Outlook folder.
Some of the mail items are ReportItems ... I can tell this because their Class = 46. However, when I try to cast the __ComObject to a ReportItem using ((Outlook.ReportItem)item) I get this exception:
AutoResolvedWinner {System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException: The operation failed.

If it helps, the MessageClass property of the object is "REPORT.IPM.Note.NDR"
Help would be appreciated.
I received the following error message when running SSIS package. The Script Task is using Microsoft Visual C# 2008. Can you please help me to fix the problem?
Thank you very much! I also attach error message:

The error message extracted from your stack trace is:
Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.
You have to remember that although when you are debugging your SSIS package you have a nice UI (BIDS or SQL Server Tools shells depending on your environment) but really it is not designed to be have a UI. What would you expect to happen when this package is deployed to a server and called by a SQL Job? i.e. Where would the message box show? Who would click "OK" to allow the thread to resume?
You probably want to just fire an information event if you are looking to post feedback, something like:
bool fireAgain = false;
Dts.Events.FireInformation(0, "Script Task", "File Modified after last load in staging", String.Empty, 0, ref fireAgain);
The error is raised because your script task is trying to display a message box and showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Therefore if you want to output a message, you could use Dts.Log instead, see the MSDN documentation for further details.
I am trying to replicate a functionality with reflection but end up getting

Can someone help me understand what i could be doing wrong with invoke method
I'm writing SSIS that scans a SQL table, create an object from each record values and need to move it next to other SSIS flow elements.
I created object type variable (MyObject) and script task.
In my script task I wrote the next code:
RequestObject reqObj = new RequestObject();
reqObj.building = Dts.Variables["reqObj_Building"].Value.ToString();
reqObj.ID = Convert.ToInt32(Dts.Variables["reqObj_DeviceID"].Value);
//...
Now I tried to write the next code in order to assin reqObj into myObject.
Dts.Variables["myObject"].Value = new RequestObject();
Dts.Variables["myObject"].Value = reqObj;
but those lines throws the next run time exception :
Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Microsoft.SqlServer.Dts.Runtime.DtsRuntimeException: The element cannot be found in a collection. This error happens when you try to retrieve an element from a collection on a container during execution of the package and the element is not there.

How can I assign custom object into SSIS Object type variable ?
It it possible?
Thanks
I don't have enough reputation to comment so I'm adding an answer instead. I did the below steps to try and replicate your problem:
Created a new script task
Created a new class in the namespace of that script
Created a variable of type Object and added to script task as Read/Write variable
Initialised the new class and assigned that value to the Object variable.
Below is my code which ran successfully. Can you please explain if there is any thing I am missing/understanding wrong?

I have an application test framework developed in C# which stores the result in an Excel file after each step. When executed inside the solution everything works fine. But when I am integrating the solution with Fitnesse and calling the method, an error is thrown. I have added the stack trace from Fitness below.
The code segment is here:
public class ExcelReports : IReporter
{
private Excel.Application xlReport;
public ExcelReports()
{
xlReport = new Excel.Application();
Excel.Workbook xlWorkbook = xlReport.Workbooks.Add();
***xlWorkbook.SaveAs(ExecutionContext.RESULTFILE);***
}
}
The error is reported at xlWorkbook.SaveAs(ExecutionContext.RESULTFILE)
