Loading Most Recent Excel File with SSIS: Script Task Debugging

I try to get the "Last modified" excel file in a folder and load it in SSIS. I found a C# code to get the name of most recent excel sheet in a folder path, and copy that in the Script Task. The code is :
using System;
using System.Data;
using Microsoft.SqlServer.Dts.Runtime;
using System.Windows.Forms;
using System.IO;
namespace ST_2e01f076aa4f46d692cf4b47f5587da9.csproj
{
[System.AddIn.AddIn("ScriptMain", Version = "1.0", Publisher = "", Description = "")]
public partial class ScriptMain : Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase
{
#region VSTA generated code
enum ScriptResults
{
Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success,
Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
};
#endregion
public void Main()
{
// TODO: Add your code here
var directory = new DirectoryInfo(Dts.Variables["User::VarFolderPath"].Value.ToString());
FileInfo[] files = directory.GetFiles();
DateTime lastModified = DateTime.MinValue;
foreach (FileInfo file in files)
{
if (file.LastWriteTime > lastModified)
{
lastModified = file.LastWriteTime;
Dts.Variables["User::VarFileName"].Value = file.ToString();
}
}
MessageBox.Show(Dts.Variables["User::VarFileName"].Value.ToString());
Dts.TaskResult = (int)ScriptResults.Success;
}
}
}
However, when I run the script task to test it, I get the following error:
I used the project name displaying in error in my code, but still does not work. Could you please kindly help me how to fix it as I am new to both SSIS and C#. Thanks

Here is an answer using Linq.
First add these namespaces
using System.Collections.Generic; //This gets you list
using System.Linq; //This allows you linq functions
//Here is your code
System.IO.DirectoryInfo di = new System.IO.DirectoryInfo(#"D:\Temp");
List<System.IO.FileInfo> fi = di.EnumerateFiles().ToList();
Dts.Variables["VarFileName"].Value = fi.Where(i=>i.Extension.ToLower()==".xls")
.OrderByDescending(i => i.LastWriteTime)
.Select(i => i.FullName).FirstOrDefault();

((SAPbouiCOM.EditText)Matrix0.Columns.Item("colCode").Cells.Item(i + 1).Specific).Value = oRset.Fields.Item("CardCode").Value.ToString();
((SAPbouiCOM.EditText)Matrix0.Columns.Item("colName").Cells.Item(i + 1).Specific).Value = oRset.Fields.Item("CardName").Value.ToString();
((SAPbouiCOM.EditText)Matrix0.Columns.Item("colEmail").Cells.Item(i + 1).Specific).Value = oRset.Fields.Item("E_Mail").Value.ToString();
oRset.MoveNext();
}
}
}
}
}
note:
My form has a matrix with three columns
The matrix is designed in Visual Studio 2015

It's because you have the s just before From near the bottom.
Change this
select CardCode,CardName,E_Mail sFrom OCRD
to
select CardCode,CardName,E_Mail From OCRD

Affect SSIS Object variable in a C# Script Task

I've created a simple script that I can't debug. Here is my issue :
I'm looking to store the content of a directory into a variable in SSIS with Visual Studio 2015.
I've created a variable in my SSIS package, and set it's data type to Object.
I've added to my package a Script Task, that contains this code :
#region Namespaces
using System;
using System.Data;
using Microsoft.SqlServer.Dts.Runtime;
using System.Windows.Forms;
using System.IO;
using System.Collections.Generic;
#endregion
namespace ST_c6399821104c42c2859b7b2481055848 {
[Microsoft.SqlServer.Dts.Tasks.ScriptTask.SSISScriptTaskEntryPointAttribute]
public partial class ScriptMain : Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase {
public void Main() {
string CSVFilesCompletePath;
if (Dts.Variables.Contains("User::CSVFilesPathAbsolute") == true
&& Dts.Variables.Contains("User::CSVFilesPathRelativeCountry") == true
&& Dts.Variables.Contains("User::CSVFilesCountryObject") == true) {
CSVFilesCompletePath = Dts.Variables["User::CSVFilesPathAbsolute"].ToString() + Dts.Variables["User::CSVFilesPathRelativeCountry"].ToString();
String[] fileListTable = Directory.GetFiles(CSVFilesCompletePath, "*.xlsx");
List<string> fileList = new List<string>(fileListTable);
Dts.Variables["User::CSVFilesCountryObject"].Value = fileList;
}
Dts.TaskResult = (int)ScriptResults.Success;
}
#region ScriptResults declaration
/// <summary>
/// This enum provides a convenient shorthand within the scope of this class for setting the
/// result of the script.
///
/// This code was generated automatically.
/// </summary>
enum ScriptResults
{
Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success,
Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
};
#endregion
}
}
As explained here :
SSIS Script Task Get File Names and Store to an SSIS Object Variable
But this code returns the following error when I try to Start it through the SSIS Job :
Variables are correctly set in the Script Wizard as ReadWriteVariables.
The thing is that my code shows this error when I try to affect the SSIS Variable and try to put the String[] in it.

Try adding a try-catch in the
Directory.GetFiles
call or in the whole body, then set the error message and/or the stack trace of the exception into a write SSIS variable for debugging purposes.
Edit: Looks like #H.Fadlallah point out the problem. You should use the Value property of the DtsVariable, not the ToString()

My error was :
CSVFilesCompletePath = Dts.Variables["User::CSVFilesPathAbsolute"].ToString() + Dts.Variables["User::CSVFilesPathRelativeCountry"].ToString();
I had to use : Dts.Variables[].Value.ToString() instead of Dts.Variables[].ToString()
As I was using the name of the Variable instead of the content of the Variable, the GetFiles returned a null object, and it couldn't be stored inside my variable, creating the different errors.

Retrieving last commit ID / revision number from a deployed application

I would like to have a function returning the last revision / commit ID of the source from which the deployed application / library was built.
I have been using the __DATE__ and __TIME__ macros in C++ but this approach has obvious drawbacks.
What tools are available to achieve this in an automated manner?
I am using Eclipse-CDT for C++ (Linux, SVN) but it I am also interested in git solutions, and sources written in Java and C#.

By using Visual Studio and C# you could within a Pre-Built step calling the SubWCRev command with a template file, that will be copied to a file used within the solution.
The command within the Pre-Built step is:
<PreBuildEvent>SubWCRev "$(ProjectDir)\" "$(ProjectDir)VersionProvider.template.cs" "$(ProjectDir)VersionProvider.cs"</PreBuildEvent>
Within the project add the following two files:
<Compile Include="VersionProvider.cs">
<DependentUpon>VersionProvider.template.cs</DependentUpon>
</Compile>
<None Include="VersionProvider.template.cs" />
With this content:
internal static class VersionProvider
{
/// <summary>
/// Provides the current subversion revision number
/// </summary>
internal const string CurrentSVNRevision = "$WCREV$";
}
Last but not least within AssemblyInfo.cs add the following line:
[assembly: AssemblyInformationalVersion(VersionProvider.CurrentSVNRevision)]
The project will by this way automatically get the current subversion revision number of this project folder baked into version info of the application which can be seen on the details page of the file properties.
You can also retrieve this information through code at runtime:
private string GetAdditionalVersionInfo()
{
var assembly = Assembly.GetEntryAssembly();
var attributesFound = assembly.GetCustomAttributes(typeof(AssemblyInformationalVersionAttribute), true);
var version = attributesFound.OfType<AssemblyInformationalVersionAttribute>().FirstOrDefault();
return version != null ? version.InformationalVersion : String.Empty;
}

/// <summary>
/// Gets the SVN date.
/// </summary>
/// <value>The SVN date. value</value>
// ReSharper disable UnusedMember.Global
public static new string SvnDate{
// ReSharper restore UnusedMember.Global
get {
const string S = "$Date$";
return S.Substring(7, 19);
}
}
/// <summary>
/// Gets the SVN ID.
/// </summary>
/// <value>The SVN ID. value</value>
// ReSharper disable UnusedMember.Global
public static new string SvnID{
// ReSharper restore UnusedMember.Global
get{
const string S = "$Id$";
const string D = "$";
return S.Replace(D + "Id: ", string.Empty).Replace(" " + D, string.Empty);
}
}
/// <summary>
/// Gets the SVN rev.
/// </summary>
/// <value>The SVN rev. value</value>
// ReSharper disable UnusedMember.Global
// ReSharper disable MemberCanBePrivate.Global
public static new string SvnRev{
// ReSharper restore MemberCanBePrivate.Global
// ReSharper restore UnusedMember.Global
get {
const string S = "$Rev$";
return S.Item(1);
}
}
/// <summary>
/// Gets the SVN author.
/// </summary>
/// <value>The SVN author. value</value>
// ReSharper disable UnusedMember.Global
public static new string SvnAuthor{
// ReSharper restore UnusedMember.Global
get {
const string S = "$Author$";
return S.Item(1);
}
}
Note S.Item(n) returns a space delimited zero based item. Replace with your own code. Also, new is only necessary to deal with inheritance. Props must be set in svn. I dont have a snippet showing the expansions since I am on Mercurial now.

If you were working with a Makefile and SVN, you could do something like this for C or C++:
REVISION=$(shell svnversion)
CFLAGS=... -D__REVISION__=\"$REVISION\"
I'm not that familiar with CDT, but I understand it's able to use a Makefile-based build system.

Display a .exe.config file in a datagridview and manipulate the settings

I'm working on a GUI that is able to manipulate xml files through a datagridview and have it saved to a destination of the user's choice. This program also has a .exe.config file in which I would also like to be able to freely edit inside a datagridview, since it's a lot more convenient than having the user manually going in to the file and changing the values accordingly.
I've tried declaring a dataset, and I intially thought that a .exe.config file was just an xml file, but this code does not work:
dataSet1.ReadXml(configpath);
bindingSource1.DataSource = dataSet1.Tables[0];
dataGridView1.DataSource = bindingSource1;
The datagridview is empty when I ran it and i confirmed that the filepath was correct and there was no exception when i debugged the code, whereas for the other xml files I open in the GUI work perfectly fine with the data displayed. Maybe readxml() only supports.. legit xml files rather than xml configuration files? I tried googling and looking for some answers, but all I got were threads related to changing the settings by manually accessing the xml file and changing the values (stuff I already know). I'm looking to be able to have the user do what they want to do with the data and then save it. The .exe.config settings may just as well be for another program, but it is essentially an xml configuration file. I figured there wasn't much on the web for this particular problem because settings are generally static and if they are changed, it's pretty easy to do manually.
To sum up,
I'm looking for a method to be able to open any .exe.config file, display it in a datagridview, allow the user to be able to manipulate the data values inside, and then save the file, overwriting the previous data settings.
Any help is appreciated.
Thank you in advance!

EDIT: I will upload a working example of an xml file I created: I kind of want the program to be able to navigate to a .exe.config file, then open it and have it displayed like this where the setting names are the columns and the values are in the cells of the datagridview. Unfortunately I am not at my home computer to be able to do this.
