Programatically Create And Configure A FlatFileConnectionManager
Jul 18, 2006
I am writing some C# code that builds a package programatically. the package contains a flat file connection manager. I have referenced Microsoft.SqlServer.Dts.Runtime.Wrapper in order that I can use the ConnectionManagerFlatFileClass class.
I get a compilation error on the last line saying I cannot implicitly cast as ConnectionManagerFlatFileClass. Fair enough, so I change the last line of code to:
Now it will compile. But when I run it I get the error:
"Unable to cast COM object of type 'System.__ComObject' to class type "Microsoft.SqlServer.Dts.Runtime.Wrapper.ConnectionManagerFlatFileClass'. COM components that enter the CLR and do not support IProvideClassInfo or that do not have interop assembly referenced will be wrapped in the __ComObject type. instances of this type cannot be cast to any other class; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface"
Can anyone tell me how I can cast the ConnectionManager.InnerObject as a ConnectionManagerFlatFileClass please?
-Jamie
P.S. My ultimate aim here is to set the metdata of each of the columns defined by the flat file connection manager. I can't see how I can do that without referring to the connection manager as a ConnectionManagerFlatFileClass!
In VS2003 I have a user defaults table that I would call in the OnLoad - No Postback section to get the user defaults and then used some of the fields from that recordset as Parameters for other recordsets that would also load in that same section and might even issue a different Sql statement based on the field. In VS2005 (VB.NET), I can no longer figure out how to accomplish this. I can use the SQLDatasource Control which seems much improved but I cannot even find the generated code which I would use as a quick way to create my own datasources in the OnLoad event. Where is this code now stored and how can I accomplish my objectives in VB.NET 2005 with the current framework or programatically create data sources as necessary as I did before?
I need some help with the following issue. I need vb.net code that will create a T-SQL script. For example given the orders table in northwind I would get the following with indexes, RI, ect. :CREATE TABLE [dbo].[Orders] ( [OrderID] [int] IDENTITY (1, 1) NOT NULL , [CustomerID] [nchar] (5) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [EmployeeID] [int] NULL , [OrderDate] [datetime] NULL , [RequiredDate] [datetime] NULL , [ShippedDate] [datetime] NULL , [ShipVia] [int] NULL , [Freight] [money] NULL , [ShipName] [nvarchar] (40) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [ShipAddress] [nvarchar] (60) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [ShipCity] [nvarchar] (15) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [ShipRegion] [nvarchar] (15) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [ShipPostalCode] [nvarchar] (10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [ShipCountry] [nvarchar] (15) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ) ON [PRIMARY]GO ALTER TABLE [dbo].[Orders] WITH NOCHECK ADD CONSTRAINT [PK_Orders] PRIMARY KEY CLUSTERED ( [OrderID] ) ON [PRIMARY] GO ALTER TABLE [dbo].[Orders] WITH NOCHECK ADD CONSTRAINT [DF_Orders_Freight] DEFAULT (0) FOR [Freight]GO CREATE INDEX [CustomerID] ON [dbo].[Orders]([CustomerID]) ON [PRIMARY]GO CREATE INDEX [CustomersOrders] ON [dbo].[Orders]([CustomerID]) ON [PRIMARY]GO CREATE INDEX [EmployeeID] ON [dbo].[Orders]([EmployeeID]) ON [PRIMARY]GO CREATE INDEX [EmployeesOrders] ON [dbo].[Orders]([EmployeeID]) ON [PRIMARY]GO CREATE INDEX [OrderDate] ON [dbo].[Orders]([OrderDate]) ON [PRIMARY]GO CREATE INDEX [ShippedDate] ON [dbo].[Orders]([ShippedDate]) ON [PRIMARY]GO CREATE INDEX [ShippersOrders] ON [dbo].[Orders]([ShipVia]) ON [PRIMARY]GO CREATE INDEX [ShipPostalCode] ON [dbo].[Orders]([ShipPostalCode]) ON [PRIMARY]GO ALTER TABLE [dbo].[Orders] ADD CONSTRAINT [FK_Orders_Customers] FOREIGN KEY ( [CustomerID] ) REFERENCES [dbo].[Customers] ( [CustomerID] ), CONSTRAINT [FK_Orders_Employees] FOREIGN KEY ( [EmployeeID] ) REFERENCES [dbo].[Employees] ( [EmployeeID] ), CONSTRAINT [FK_Orders_Shippers] FOREIGN KEY ( [ShipVia] ) REFERENCES [dbo].[Shippers] ( [ShipperID] )GO
I created a SSIS package, added Script task. created data flow task programatically, trying to add a flat file source component programatically. stuck at this point.
my goal is to add flat file source component to the data flow task and insert into a table in sql server using oledb destination component all programatically.
i am working on a small "Biztalk" engine, by creating dynamic ssis packages that change according to the client source file definition.
in order to create a row-number to each row in my input file, i am tryng to add the Konesans's Row Number component to the dynamic package by using SSIS API, but i get a lot of errors. the component is not created as a"rowNumber" component, but as a General Managed Component, though i use the ComponentClassID as the classID in the RowNumber component.
has anybody try to do this ?
is there any way to get the row number other then this way?
My vb .net app creates programatically a package. I mean, you can provide name, description, number of OLEDB/ADO connections, variables and so on, where it's stored, from a WinForm.
Up to the moment, process only creates boxes separately wihtout links.
My concern is after this successful cycle I only can open that DTSX and see its components but executing button is disabled (only possible with DTEXECUI.exe) from BIDS.
Only when I create a project (DTSPROJ) and then I put that same .DTSX inside I am be able to execute it.
Well, up to here all of this is very good. Things were created this way for some reason.
My question now is how do I from my application in order to create dtsproj and dtsproj.user (I don't know how many files are needed) and be able to create a package and its "father project". My idea is that the user can choose if create a standalone DTSX or a full project.
I have to create a DSN for SQL-Server. Therefor I use the function "SQLConfigDataSource" from "ODBCCP32.DLL". But the problem is that the SQL-Server does not use the Standard-Portnumber 1433. I've tried to make the DSN with "SERVERNAME xxxx" where xxxx is the Portnumber, sometimes it works, but often it does not. When it does not work, then the Checkbox in the ODBC-Configuration-Tool is checked, so the connection is searching for the standard-port. How can I tell the system that it shall NOT use dynamic configuration?
I am using Visual Studio 2008 and have created a .mdf database within my project. I want to be able to do a few things and I am not quite sure where to start. The program I am writing manages rental properties. Thus, each rental property that the user owns needs its own sql express database. For this to work:
1. I need to be able to dynamically create a database for each property that the user owns. Is it best to do this as described here http://msdn2.microsoft.com/en-us/library/bb399420.aspx ? Or is it best to have a template database and then make a duplicate of the database using the File.Copy() method.
If it is best to do it programatically as shown in the link above, how do you create relationships between tables?
2. I need to be able to dynamically add users to the database via c# code. How does one do this? Is it possible do through LINQ?
Hopefully someone can point me in the right direction. Thanks

Can anyone please direct me to an easy to understand Description, Article or Video tutorial that shows an example on how to programatically connect to an SQL database and retrieve data from a collumn using C# and VISUAL WEB DEVELOPER 2005 EXPRESS EDITION. Also, what namespace should be imported to do this? (From what I have gathered out of the help, it seem that System.Web.UI.WebControls is the one) I am trying to create a "news letter" web page. I have a basic form and when I hit "send" then the code in the background should access the database with all the recipient info, and retrieve all the E-mail addresses, Names, etc. and include it in each e-mail. ( I don't know if it is just me, but the help included with VISUAL WEB DEVELOPER 2005 EXPRESS EDITION is extremely difficult to understand - from a beginner point of view). Thanks! Regards Jan
Hi, I've written a SELECT statement that returns columns dependant on a bitwise parameter @Populate.SELECTCASE WHEN (1 & @Populate) = 1 THEN [Column1] ELSE Null END AS [Column1],CASE WHEN (2 & @Populate) = 2 THEN [Column2] ELSE Null END AS [Column2],CASE WHEN (4 & @Populate) = 4 THEN [Column3] ELSE Null END AS [Column3],CASE WHEN (8 & @Populate) = 8 THEN [Column4] ELSE Null END AS [Column4],etcIs this the most efficient way to acheive this since I am only seeing a small performance gain. It still returns all columns but depending on @Populate will leave some columns with Null values.Any help much appreciated, thanks.
Hi All, I am having problems getting values out of an sqldatasource. I have 2 on the page, i am using one to insert into a table and the other to get a couple of values from another table for the insert. the datasource i am trying to get the values from does a select with a querystring filter i need to grab a couple of fields out of it trhen do the insert on the other datasiource with a button click. The insert is fine, i just don't know how to get the values out of the first 'select source' Any pointers or suggestions most appreciated. Cheers
hi i am trying to gernerate some tables ( first with a script and then with a stored procedure),, in ms server management studio exrress 2005 using the followingcreate table ip( id int IDENTITY NOT NULL, ip varchar(15) NOT NULL, hostname varchar(128) NOT NULL, primary key(id)) ; i store this in a new query (assume :right click associates the query to the current database ?) and run it and nothing happens its been a while since i did sql but i think the sql is ok....how or more specifically where is the appropriate place to run this code thankssimo stored as a new query
I have a list box populated by a SqlDataSource with a basic statement of Select name where location = @location. Location is bound to a dropdownlist control. I want to have a checkbox for the Location dropdownlist and a checkbox for another dropdownlist (for the alphabet) that will select only those people with a last name of the letter selected. Changing the checkbox would change the sql statement. OK so there are two questions here: 1. How can I write a sql statement that would select only people whos last name begins with a certain letter. Would it use some sort of convert function to a string with only 1 letter? 2. How can I programatically change the sqlDataSource's 'select' statement. I need to switch between sorting by location and sorting by alphabetical last name. All of my previous experience has had me configuring the datasource in the asp.net code.
Hi SQ Gurus, Please help me with this issue that I am facing. I want to create a table programatically but want to pass its name as a variable. I would like to do something as follows: CREATE PROCEDURE BS_Create (@Name nvarchar(25)) AS CREATE TABLE [dbo].[@Name]( [ID] [int] IDENTITY (1, 1) NOT NULL , [Prod_Name] [nvarchar] (75) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ) ON [PRIMARY] GO The table name is passed in as a parameter. No matter what I pass as a parameter, the table name is '@Name', which is not what I want. Instead, if the variable contains the value 'Product', I would like to see a table with the name 'Product' to be created.
OK, so I'm working on a project that requires the dynamic generation of SQL statements. Now in Visual Studio .NET I'm sure many of you have used that wonderful visual database tool that allows you to magically "verify sql syntax" at the click of a button. It takes a query that looks like this:
"SELECT A.AFFID, A.UserName, A.Pass, A.FirstName, A.LastName, A.Company, A.Street, A.City, A.State, A.ZIP, A.Country, A.phone, P.EMail, A.RecieveEMail, A.SSN, A.JoinDate, A.AffType, P.ProductId, P.BuyerId FROM Affiliates A, Purchases P WHERE (ProductId > 0) ORDER BY 1"
and transforms it into something that looks like this:
"SELECT A.AFFID, A.UserName, A.Pass, A.FirstName, A.LastName, A.Company, A.Street, A.City, A.State, A.ZIP, A.Country, A.phone, P.Email, A.RecieveEMail, A.SSN, A.JoinDate, A.AffType, P.ProductID, P.BuyerID FROM Affiliates A CROSS JOIN Purchases P WHERE (P.ProductID > 0) ORDER BY A.AFFID"
My question is: is there anything in the .NET platform that would allow me to achieve the same kind of result programatically (i.e. transform standard sql to tsql syntax and verify the syntax of the query at run time)?
HiI'm trying to access the properties of my datasource programatically so I can change the stored procedure it connects to depending on the value of a querystringIn my page load I have Dim myMode = Request.Params("mode")Select Case myMode Case "Category" sqldatasource1.SelectCommand = "productsbycategory" sqldatasource1.SelectCommandType = SqlDataSourceCommandType.StoredProcedure ******'Need to add querystring parameter Case "Wishlist" sqldatasource1.SelectCommand = "productsbywishlist" sqldatasource1.SelectCommandType = SqlDataSourceCommandType.StoredProcedure ******'Need to add Session variable parameter Case Else sqldatasource1.SelectCommand = "allProducts" sqldatasource1.SelectCommandType = SqlDataSourceCommandType.StoredProcedureEnd SelectThe problem that I have is that I need to pass a parameter to the first 2 procedures above, a querystring to the first and a session variable to the second.How do I add parameters programaticallyMany thanks
Hi , Could anybody point me to an NT/DOS script ( e.g a batch file ) that could check if the MSSQL Server and SQL Server Agent Services are running ?
I am trying to write the following script to check for the status. Each of the following commands gives a 1 as output if the service is running and 0 if it is not. The problem I am facing is that I am not able to check the output after the command is executed. I am neither able to assign it to a variable or include the whole command in an IF statement.
net start | find /c /i "MSSQLServer" net start | find /c /i "SQLServerAgent"
Is there any other way to do this programmatically ? Any help is greatly appreciated.
I am trying to figure out a way to restore a database programatically. Here is how I do it now. Right click on the database, select Restore. Browse out to my computer and find the .BAK file. Select the database and go into 'Restore Options' I have to physically change the .MDF and .LOG paths since I am getting this backup is not coming from my computer. I select 'Overwrite the existing database' then click restore.
My problem is that I have to change the paths to the MDF and LOG files. How could I automate this? Thank you!!

Lets say you have to retrieve some SQL.Then you have to go through those records and delete some items, change some values, and even add columns and rows...based on logic that depends on the data you got.Thanks.
This is my first attempt to create a Vb.net class as well as my first attempt to programmatically view SQL retrieved data as opposed to using the built-in data controls...so be gentle.My question is looking at the code below which I have already put together...how do I actually see what the data is in a particular column... One of my columns for example is the "Title" which contains the Page Title for Search Engine Optomization. I need to be able to read this value so I can assign it to the Page.'First Do a Database ConnectionIf Not Page.IsPostBack Then'Start by determining the connection string valueDim connString As String = _ConfigurationManager.ConnectionStrings("CMConnectionString").ConnectionString'Create a SqlConnection instanceUsing myConnection As New SqlConnection(connString)'Specify the SQL queryConst sql As String = "SELECT * FROM SEO where ParentType='Department' AND ParentLevel='0' "'Create a SqlCommand instanceDim myCommand As New SqlCommand(sql, myConnection)'Get back a DataSetDim myDataSet As New DataSet'Create a SqlDataAdapter instanceDim myAdapter As New SqlDataAdapter(myCommand)myAdapter.Fill(myDataSet, "SEO")'Create a DataViewDim myDataView As New DataViewmyDataView.Table = myDataSet.Tables("SEO")'Ok...this is where I'm lost. Now how do I look up the value for the column "Title" in this Dataset'Close the connectionmyConnection.Close()'End database connectionsEnd Using

If I want to create an SQL data table on the server, I go to Server Explorer and make a small table with the corerct columns. Then I add rows programatically as needed from the Application I'm working with.
It would suit me, for a current job, to be able to create the table itself programatically.
I don't know how to do this. Can it be done ? If so, could someone give me a starter, please ? Four cols with a key in the first.
I am crateing the database on the fly using db directory in VC++. I am able to create database. I am also able to create login. These can be easily done by logging as master using the username and password sa and "" resp. Now I want to add a user to the database that i created. but it is being added to the master database. I know that I have to change my login from sa ,"" to the username and password that i gave during login. but i dont know how to change the login. Please help. If you have any code for that then that will be of great help. Hoping to get a positive response as soon as possible.. Thanx Nitin Gulati
