I've been trying to piece together how other users have finished their projects, but my understanding is still limited.
I want to take any given XML source, make a Data Flow Task, and pass its data to an OLE DB destination matching the table name of the XML file. Running it with the visual tool means I cannot do dynamic data flow tasks because the Metadata does not refresh.
I have created a script that creates a package, but when I open the package in Visual Studio, it has a red-x saying that there cannot be zero Input Columns. When I drill down and look at the mappings of the OLE DB Destination, then click OK - it corrects it for me. I cannot figure out how to do that programmatically.
I've seen others solve it by using foreach loops and going through the Input columns, but I cannot seem to figure it out.
I also have a separate script that I tried to mimic several people's scripts with, and it has different issues. Not sure how to post it as an attachment
Thank you in advance for the help :)
EDIT
I've been getting positive feedback for trying out BIML, and I will...but I want to know if in the short term anyone can help me figure out why this doesn't fill in ExternalMetaDataColumnId for my input. I've posted my updated code below with foreach loops that aren't doing what I expect them to.
Thank you

I think the problem that you are not mapping the input columns to the OLEDB Destination, and after opening the package, if you click on the OLEDB Destination and go to the Mapping section, it will automatically map the columns based on their names. The Foreach loop that is used by others are to loop over columns and map them to the related Destination columns.
There are many articles talking about creating SSIS package dynamically, you can refer to them for more information:

In my application, there is a need to create an excel file which should have an auto-completion feature. Suppose I am fetching some values "Data 1","Data 2" from the database, after fetching I want to bind those values to a particular column of excel. So when a user types something it would prompt "Data 1","Data 2"...
How to achieve this? help needed
You are describing a feature called Data Validation. It's main purpose is to limit the possible values of a cell to a certain range but, as you have spotted, this has the handy side-effect of having Excel show a drop down of the available values.
You can do something like this using various openXML libraries which allow you to create .xlsx files in .NET code. I like EPPlus which would let you do something like this:
static void Main(string[] args)
{
var fInfo = new FileInfo("output.xlsx");
using (var excel = new ExcelPackage())
{
var sht1 = excel.Workbook.Worksheets.Add("DataSheet1");
sht1.Cells[1,1].Value = "Occupation:";
var validation = sht1.DataValidations.AddListValidation("A2");
foreach(var allowedValue in GetAllowedValues())
{
validation.Formula.Values.Add(allowedValue);
}
excel.SaveAs(fInfo);
}
}
private static IEnumerable<string> GetAllowedValues()
{
return new string []{"Doctor","Baker","Candlestick Maker"};
}
This gives the dropdown list you are referring to (my screengrab is from LibreOffice but you will see the same effect in Excel):
I'll start by asking am I right in thinking that in the image below:
the 'TABLE=CLOASEUCDBA.T_BASIC_POLICY' is not part of the connection string? in fact it is the source table name?
I'm looking to alter this to another linked table on the same database. The connection string should there be the same and the name that appears in ACCESS should be the same. The only difference should be under the hood it is actually referencing another table and of course if you open the table it will contain different fields and data.
my code for far to do this is:
var dbe = new DBEngine();
Database db = dbe.OpenDatabase(#"C:\Users\xxxx\Documents\Test.accdb");
foreach (TableDef tbd in db.TableDefs)
{
if (tbd.Name.Contains("CLOASEUCDBA_T_BASIC_POLICY"))
{
tbd.SourceTableName = "CLOASEUCDBA_T_BILLING_INFORMATION";
}
}
db.Close();
However I'm getting a big fat COMException "Cannot set this property once the object is part of a collection.". I'm not sure exactly why and all the examples I can find online are all written in VB/VBA and I only have very very limited exposure to this. Any help is appreciated.
EDIT:
I have tried to go a different route with no futher success using the code:
if (tbd.Name.Contains("CLOASEUCDBA_T_BASIC_POLICY"))
{
var newtable = db.CreateTableDef("this is a new table");
newtable.Name = "new table";
newtable.Connect = tbd.Connect;
newtable.SourceTableName = "CLOASEUCDBA_T_BILLING_INFORMATION";
db.TableDefs.Append(newtable);
//tbd.SourceTableName = "CLOASEUCDBA_T_BILLING_INFORMATION";
}
In this case I get the error "ODBC--call failed."
Since we're not allowed to change the SourceTableName of a TableDef object that already exists in the TableDefs collection we need to create a new TableDef object, .Delete the old one, and then .Append the new one:
// This code requires the following COM reference in your project:
//
// Microsoft Office 14.0 Access Database Engine Object Library
//
// and the declaration
//
// using Microsoft.Office.Interop.Access.Dao;
//
// at the top of the class file
string tableDefName = "CLOASEUCDBA_T_BASIC_POLICY";
var dbe = new DBEngine();
Database db = dbe.OpenDatabase(#"C:\Users\xxxx\Documents\Test.accdb");
var tbdOld = db.TableDefs[tableDefName];
var tbdNew = db.CreateTableDef(tableDefName);
tbdNew.Connect = tbdOld.Connect;
tbdNew.SourceTableName = "CLOASEUCDBA_T_BILLING_INFORMATION";
db.TableDefs.Delete(tableDefName); // remove the old TableDef ...
db.TableDefs.Append(tbdNew); // ... and append the new one
db.Close();
tl;dr
What is the EzAPI code to use an OLE DB Source with data access mode of "SQL command from variable" and assign a variable?
Preamble
Once a month, we need to refresh our public test site with subsets of production data. We have determined that for our needs, an SSIS solution provides the best fit for accomplishing this task.
My goal is to systematically build a large number (100+) of "replication" packages. EzAPI is a friendly wrapper to the SSIS object model and it seems like a great way to save mouse-clicks.
I would like for my packages to look like
Variable - "tableName"; [Schema].[TableName]
Variable - "sourceQuery"; SELECT * FROM [Schema].[TableName]
DataFlow - "Replicate Schema_TableName"
OLE DB Source - "Src Schema_TableName"; Data Access Mode: SQL command from variable; Variable name: User::sourceQuery
OLE DB Destination - "Dest Schema_TableName"; Table or view name variable- fast load; Variable name - User::tableName
Code
This is the code for my table to table replication package.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SqlServer.SSIS.EzAPI;
using Microsoft.SqlServer.Dts.Runtime;
namespace EzApiDemo
{
public class TableToTable : EzSrcDestPackage<EzOleDbSource, EzSqlOleDbCM, EzOleDbDestination, EzSqlOleDbCM>
{
public TableToTable(Package p) : base(p) { }
public static implicit operator TableToTable(Package p) { return new TableToTable(p); }
public TableToTable(string sourceServer, string database, string table, string destinationServer) : base()
{
string saniName = TableToTable.SanitizeName(table);
string sourceQuery = string.Format("SELECT D.* FROM {0} D", table);
// Define package variables
this.Variables.Add("sourceQuery", false, "User", sourceQuery);
this.Variables.Add("tableName", false, "User", table);
// Configure DataFlow properties
this.DataFlow.Name = "Replicate " + saniName;
this.DataFlow.Description = "Scripted replication";
// Connection manager configuration
this.SrcConn.SetConnectionString(sourceServer, database);
this.SrcConn.Name = "PROD";
this.SrcConn.Description = string.Empty;
this.DestConn.SetConnectionString(destinationServer, database);
this.DestConn.Name = "PREPROD";
this.DestConn.Description = string.Empty;
// Configure Dataflow's Source properties
this.Source.Name = "Src " + saniName;
this.Source.Description = string.Empty;
this.Source.SqlCommand = sourceQuery;
// Configure Dataflow's Destination properties
this.Dest.Name = "Dest " + saniName;
this.Dest.Description = string.Empty;
this.Dest.Table = table;
this.Dest.FastLoadKeepIdentity = true;
this.Dest.FastLoadKeepNulls = true;
this.Dest.DataSourceVariable = this.Variables["tableName"].QualifiedName;
this.Dest.AccessMode = AccessMode.AM_OPENROWSET_FASTLOAD_VARIABLE;
this.Dest.LinkAllInputsToOutputs();
}
/// <summary>
/// Sanitize a name so that it is valid for SSIS objects.
/// Strips []/\:=
/// Replaces . with _
/// </summary>
/// <param name="name"></param>
/// <returns></returns>
public static string SanitizeName(string name)
{
string saniName = name.Replace("[", String.Empty).Replace("]", string.Empty).Replace(".", "_").Replace("/", string.Empty).Replace("\\", string.Empty).Replace(":", string.Empty);
return saniName;
}
}
}
Invocation looks like TableToTable s2 = new TableToTable(#"localhost\localsqla", "AdventureWorks", "[HumanResources].[Department]", #"localhost\localsqlb"); and that builds a package that does what I want except for using a variable in the source.
Problem
The above code supplies the access mode as SQL Query and the query is embedded in the OLE Source. The desire it to use "SQL Command From Variable" and that variable being #[User::sourceQuery] What I'm stuck on is using a variable in the source.
It should be a simple matter of assigning something like
this.Source.DataSourceVariable = this.Variables["sourceQuery"].QualifiedName;
this.Source.AccessMode = AccessMode.AM_SQLCOMMAND_VARIABLE;
This results in the correct data access mode selected but the variable isn't populated.
You can observe that I perform a similar step in the destination which does accept the variable and works "right."
this.Dest.DataSourceVariable = this.Variables["tableName"].QualifiedName;
this.Dest.AccessMode = AccessMode.AM_OPENROWSET_FASTLOAD_VARIABLE;
What doesn't work
Listing out the permutations I've attempted
this.Source.AccessMode = AccessMode.AM_OPENROWSET;
Results in Data Access Mode set to Table or View and name of table or the view is blank.
this.Source.AccessMode = AccessMode.AM_OPENROWSET_VARIABLE;
Results in Data Access Mode set to "Table or view name variable" and variable name is sourceQuery. Very close to what I want, except the access mode is not correct. Were this package to run, it'd blow up as the OpenRowSet would expect a straight table name.
this.Source.AccessMode = AccessMode.AM_SQLCOMMAND;
Results in Data Access Mode set to "SQL Command" and the SQL command text is "User::sourceQuery" That's the literal value of the variable name so it's the right thing but since the access mode is wrong, it doesn't work.
this.Source.AccessMode = AccessMode.AM_OPENROWSET_FASTLOAD;
this.Source.AccessMode = AccessMode.AM_OPENROWSET_FASTLOAD_VARIABLE;
Niether of these are correct access modes as they are for destinations (I still tried them but they didn't work as expected).
At this point, I thought I'd try to work backwards by creating a package that has the OLE DB source defined as I want it and then inspect the source object's properties.
Application app = new Application();
Package p = app.LoadPackage(#"C:\sandbox\SSISHackAndSlash\SSISHackAndSlash\EzApiPackage.dtsx", null);
TableToTable to = new TableToTable(p);
My code has set both SqlCommand and DataSourceVarible with the variable's qualified name. I've pulled down changeset 65381 and compiled that (after fixing some references to the SQL Server 2012 dlls) in hopes there might have been a fix since the Dec 30 2008 Stable build but to no avail.
Have I found a bug in their code or am I just missing something?
The current, stable build of EzAPI does not support the assignment of a variable as an OleDB Source property. I opened a similar discussion over on CodePlex and ended up learning more about how all of this works.
The root problem is the related property "SqlCommandVariable" should be set when the access mode is set to "SQL Command from Variable." Currently, the code only covers destination variables.
My resolution was to download the source code and modify the setter for the property DataSourceVariable in EzComponents.cs (line 1027 for changeset 65381)
set
{
m_comp.SetComponentProperty("OpenRowsetVariable", value);
if (AccessMode == AccessMode.AM_SQLCOMMAND_VARIABLE)
{
m_comp.SetComponentProperty("SqlCommandVariable", value);
}
ReinitializeMetaData();
}
If you're looking to get this problem resolved properly, you may upvote the Issue
Try swapping around
this.Source.DataSourceVariable = this.Variables["sourceQuery"].QualifiedName;
this.Source.AccessMode = AccessMode.AM_SQLCOMMAND_VARIABLE;
to
this.Source.AccessMode = AccessMode.AM_SQLCOMMAND_VARIABLE;
this.Source.DataSourceVariable = this.Variables["sourceQuery"].QualifiedName;
I've discovered that the order matters more than it does with a typical API.
I have a program that uses clipboard but I want to restore the clipboard to its former state after I am done with it.
This is my code :
IDataObject temp = Clipboard.GetDataObject();
//Some stuff that change Cliboard here
Clipboard.SetText("Hello");
//Some stuff that change Cliboard here
Clipboard.SetDataObject(temp);
But it if I copy a text, and run this code, I get nothing on notepad.
NOTE : I can't use Clipboard.Contains because I want to preserve the Clipboard EXACLY how it was before, even if the user copied a file.
I cannot confirm whether this will work, but I see no reason why you shouldn't be able to back up the data using the longer approach of actually reading the data and restoring it afterwards.
Read here: http://msdn.microsoft.com/en-us/library/system.windows.forms.idataobject.aspx
You would do something like (pseudo-code)
//Backup
var lBackup = new Dictionary<string, object>();
var lDataObject = Clipboard.GetDataObject();
var lFormats = lDataObject.GetFormats(false);
foreach(var lFormat in lFormats)
{
lBackup.Add(lFormat, lDataObject.GetData(lFormat, false));
}
//Set test data
Clipboard.SetText("asd");
//Would be interesting to check the contents of lDataObject here
//Restore data
foreach(var lFormat in lFormats)
{
lDataObject.SetData(lBackup[lFormat]);
}
//This might be unnecessary
Clipboard.SetDataObject(lDataObject);
Is your application exiting after resetting the clipboard?
Assuming it is a Win Form app. (not sure how it works in wpf though)
You could use one of the other overloaded version of Clipboard.SetDataObject
public static void SetDataObject(object data, bool copy)
which preserves the data even after your app exits.
ex: in your case after removing the text content you could call Clipboard.SetDataObject(iDataObject, true);
EDIT:2
I Could source step through Clipboard.cs .NET Frameword 4 / VS 2010.
Download the .NET Framework 4 from here http://referencesource.microsoft.com/netframework.aspx.
Follow the below steps and if it asks for the source (Clipboard.cs) it would be in the Source sub-dir of the installation dir.
EDIT:1
Not sure why the same code doesn't work.
Cannot be a security/permission issue as the code doesn't throw an exception as you say.
There is another approach - source stepping into Framework code - Clipboard.cs
Based on the VS version and .NET framework it may vary ( I couldn't get the source stepping work for .NET 4 as the info is that the symbols with source support haven't yet been released). I'm trying my luck by downloading it manually from here (.NET Version 4)
If you are running VS 2008 and older version of .NET then the below steps should work for you.
More details are here. For .NET Framework 4 - here
This cannot be done. You cannot backup/restore the clipboard without causing unintended consequences.
Please see my post on a similar question. My answer is the one that starts with "It's folly to try to do this".
How do I backup and restore the system clipboard in C#?
Furthermore, I suspect that your motivation for wanting to backup/restore the clipboard is because you want to use it as a crutch to move data, without the user's knowledge or consent. Please read:
http://www.clipboardextender.com/developing-clipboard-aware-programs-for-windows/common-general-clipboard-mistakes
and
http://www.flounder.com/badprogram.htm#clipboard
Lastly, please read and understand this quote:
“Programs should not transfer data into our out of the clipboard without an explicit instruction from the user.” — Charles Petzold, Programming Windows 3.1, Microsoft Press, 1992
I tested the pseudocode from Lukas and found out doesn't work always, this works in all my tests:
// Backup clipboard
lBackup = new Dictionary<string, object>();
lDataObject = Clipboard.GetDataObject();
lFormats = lDataObject.GetFormats(false);
foreach (var lFormat in lFormats)
{
lBackup.Add(lFormat, lDataObject.GetData(lFormat, false));
}
//Set test data
Clipboard.SetText("asd");
//Restore clipboard
lDataObject = new DataObject();
foreach (var lFormat in lFormats)
{
lDataObject.SetData(lFormat, lBackup[lFormat]);
}
//This might be unnecessary
Clipboard.SetDataObject(lDataObject);
I have had success with this.
...to a certain degree.
Where I am currently falling down is trying to copy and restore Bitmaps of varying size.
I can successfully copy and restore a Bitmap of smallish size.
I then tried to do the same for (as the fore-warning Chris Thornton suggested) a gargantuan Excel worksheet with both thousands of cell data, as well as two sets of data on a graph, lying on the same worksheet.
I have found that the data copies and restores without problem. Where it falls down in this instance is allowing the 2-set graph with the worksheet copy.
If any of you have had a problem in copying and restoring Bitmaps, let me suggest what worked for me: when attempting to restore the Clipboard, iterate through the list of formats in reverse order and set each data object that way. (i.e. It seems that a Clipboard must be set in reverse order that it was copied in)
Regarding the case of the gargantuan Excel worksheet and accompanying graph, I also hit another stumbling block: I could not successfully copy the data object whose format was "Meta Data File". That could be the reason why Copy/Restore doesn't work in this case.
I got this far about two weeks ago, and tabled it for more pressing issues.
I wanted to put this out there to let anyone else trying to do the same that it seems like it can be done. (anything can be done in computer science. anything.)

I have so far found a couple of sources that discuss creation of ODS files: How to create ODS documents in .Net and
How to create .odt files with C#.NET?
And most interestingly an explanation for opening calc files. However this opens OpenOffice in fullscreen, what im looking for is some way to write to a Calc file (.ods) without actually opening Openoffice. So that I can write a function that just opens a savefiledialog, gets the filename and then creates and saves the .ods file.
Are there is any C# code examples available to do such a thing?
So I have finally resolved this issue and want to save others the hazel of going through this again. Basic points of HEADACE for me were:
Use forward slashes instead of backward slashes (e.g. its C:/ not C:\ )
The Filtername used should be set to the engine used to save the document. Possible values include writer8, calc8, MS Excel 97, so for spreadsheets you obviously need to use calc8
If you dont want that OpenOffice pops up in the forground and wait for it to get filled with your data, then use the PropertyValue and set Hidden to true.
