    - Why is this login failing? I am using VS in conjunction with SQL Server 2000. I am trying to create a new SQLConnection but am getting an error message of "Login failed. Not associated with a trusted SQL Server Connection" I drag a SQLConnection to my components tray. In the Connection String property I say New connection. I give the server name (which is the name of my computer) and put the radio on specific name and password. I enter a user name of sa and a password of xxx. I click on the field "Select the database on the server" and get the above mentioned error, followed by "Login failed, Catalog info can not be retrieved". In the past I have solved this problem by going into SQL Server and in the Server, Properties, Security tab changing the authenication to SQL Server and Windows. My notes indicate that in the past when I've had this problem it was because the authentication was not set to mixed. However this does not seem to fix the problem in this case. Does anyone have any idea what's going on? Tag: how can I get the path for the error ORA-01458 Tag: 62826

    - Extending Typed "DataTables" I am facing the following problem in my applications and would like suggestions from you guys. My database schema has changed many times over the years and keeps chaging frequently according to specific client needs. My business layer (webservices) returns datasets to the thick client. The problem is that as the database changes so often, more than 800 datasets will have to be changed everytime. The solution suggested was as follows: a) Create 1 DataTable for each TABLE in the database. b) Create own DataSet for each visible screen or processing function by addind DataTables to this DataSet. c) Add Ref Contraints manually to this custom DataSet. This way, if the database changes, only one single DataTable class (schema) in the application will have to be changed. Now my problem is that i want to use Typed Datasets and Typed DataTables. What would be the best solution for this scenario. As mentioned on MSDN, DataTables can be instantiated independent of DataSets. In this case, the schema for the DataTable and the constraints are added manually in the code. But I could not find anything about extending Typed DataTables and using them independent of the DataSet. There is a powertoy by Shawn Wildermuth that helps you extend Typed DataSets, but i couldn't extrapolate his ideas to fit my requirements. Any ideas what the best thing for me would be ?

    - DataTable Events? I am getting started with DataTables and the DataGrid control. I want to find out when the user adds a row to a DataGrid, but I can't find a 'new row' or 'row added' method in either the DataGrid control or the DataTable class. I have bound a DataGrid to a stand-alone, in-memory DataTable. The user can edit the DataGrid cells and add new rows. When the user adds a new row, the calls all show "(null)", since they don't yet have values. I'd like to know when the user adds a new row, so I can plug in some default values, or do something to supress the "(null)" display in the cells. Is there an easy way to do that? Is an event fired when a user adds a new row? Thanks. -- Dave Veeneman davidv@nospam.com (actual domain is my last name) Tag: how can I get the path for the error ORA-01458 Tag: 62748

    - Autoincrement Key values in Relationships ADO.NET and Autoincrement fields. Recently, while attempting to use .NET to build an interface for a new system, I came upon the issue of using Autoincrement fields as Key values. In and of themselves, they are not terribly troublesome, but when used as part of a Key defining a Parent-Child relationship, things get a little sticky. Per the MicrosoftPress book, ADO.NET by David Sceppa, handling Autoincrement values in Parent-Child relationships is no bother at all. In chapter 11 - Advanced Updating Scenarios : Section 'Working with Autoincrement Values and Relational Data', Sceppa states, (after fetching the new Autoincrement value for the Parent record from the database)"...how do you apply the new Autoincrement values to the pending new line items? Actually, you don't. You let ADO.NET do the work for you through the DataRelation.". That statement is only half right. ADO.NET will in fact update the values through the DataRelation, but in the process, it changes the RowState of the (child) records from 'Added' to 'Modified'. Since this property is read- only, this effectively prevents the child records from being INSERTed into the database (because the DataAdapter now believes these records are NOT NEW, but simply existing records that have been modified. Using this methodology, your detail data will never get stored to the Database. Ever. In his book, Sceppa also discourages the use of Autoincrement values in favor of the GUID. Since that value can be generated by either the client or server, it is much easier to handle since you do not need any special code to retrieve the values from the Database after the row has been added. Except for the fact that GUID values CAN BE DUPLICATED, and the fact that they are four times larger than an (SQL)Int, this would probably be a good suggestion. Even if the uniqueness could be guaranteed, who wants to use a 16-byte random 'string' as a key value for lookups and cross referencing between tables!?!? After fighting with this particular issue for several days (and nights), and repeated attempts to find something resembling an answer on Microsoft's many websites, I found something that actually works, and is not terribly difficult to achieve. I would like to say that the idea, if not the code, came from Microsoft. It didn't. Let's use the standard ORDERS and ORDERDETAILS tables to illustrate.... ORDERS : PrimaryKey = (ORDER_ID) --------------------------------- ORDER_ID : Autoincrement (-1, -1) CUSTOMER_ID : Int .... ORDERDETAILS : PrimaryKey = (ORDER_ID + LINEITEM_ID) ---------------------------------------------------- ORDER_ID : Int LINEITEM_ID : Int .... DataRelation -------------------------------- Parent : ORDERS("ORDER_ID") Child : ORDERDETAILS("ORDER_ID") Let's say that a single new order has been added to the DataSet and has been assigned an ORDER_ID of -1. the new records would look something like this... ORDERS.Rows(0)("ORDER_ID") = -1 ORDERS.Rows(0)("CUSTOMER_ID") = 7026 .... ORDERS.Rows(0).RowState = Added ORDERDETAILS.Rows(0)("ORDER_ID") = -1 ORDERDETAILS.Rows(0)("LINEITEM_ID") = 27 .... ORDERDETAILS.Rows(0).RowState = Added In order for the Database assigned Autoincrement value to propagate to the child table in the relationship, you need to use the Parent tables Select method, and NOT GetChanges since GetChanges will not cascade the values to the ORDERDETAILS DataTable. The call would look something like this.... nEffectedRows = sdaORDERS.Update(ds.ORDERS.Select ("ORDER_ID < 0")) ----->Insert statement is as follows.... "INSERT INTO dbo.ORDERS(CUSTOMER_ID) "_ "VALUES (@CUSTOMER_ID) ; "_ "SELECT ORDER_ID, CUSTOMER_ID FROM dbo.ORDERS "_ "WHERE (@ORDER_ID = @@IDENTITY)" This will add the new ORDER record to the Database and return the new database assigned ORDER_ID, which in turn is stored in the appropriate ORDERS datarow. If the DataRelation is set up correctly and in effect, the ORDER_ID values in the Child record(s) will also be updated with the correct ORDER ID. This makes our records look like this... ORDERS.Rows(0)("ORDER_ID") = 99 ORDERS.Rows(0)("CUSTOMER_ID") = 7026 ORDERS.Rows(0).RowState = Unchanged ORDERDETAILS.Rows(0)("ORDER_ID") = 99 ORDERDETAILS.Rows(0)("LINEITEM_ID") = 27 ORDERDETAILS.Rows(0).RowState = Modified ... This brings us to the problem with using this method. At this point, we have called the Update method for the ORDERS DataAdapter, but NOT for the ORDERDETAILS DataAdapter. If you look at the RowState for the ORDERDETAILS row you will see that it has been changed from 'Added' to 'Modified'. If you now try to send this row to the DataAdapters Update method, it will attempt to UPDATE it rather than INSERT it. Obviously this fails since the row does not exist in the Database. What makes this really fun to deal with is the fact that the RowState property is READONLY. Microsoft does not offer any solution to this. Sceppa is obviously unaware of this problem since he goes on to say, "Once the new rows in the order details DataTable contain the appropriate values for the OrderID column, you can successfully submit the pending new rows to your database". No biggie. It's not the first time Microsoft has left out a detail or two. Solution. It took me about 5 days to find a combination of tactics that actually worked. The sequence of events are the same as what is described above, but with a couple of extra steps tossed in. The solution itself isn't terribly difficult to code, infact it's rather simplistic. What made it difficult was trying to do it 'their way'. The brief run-down is as follows.... <data has already been added - we are about to update the database with our changes > //------------------------------------------------------ //------------------------------------------------------ Dim xx, yy As Int16 Dim tOrdersAry() As DataRow Dim tDetailsAry() As DataRow ' Get our array of (POINTERS to) the ADDED ROWS... tOrdersAry = _ ds.ORDERS.Select("", "ORDER_ID", Added) tDetailsAry = _ ds.ORDERDETAILS.Select("", "ORDER_ID", Added) ' Now, update the ORDERS Table with the NEW records... xx = sdaORDERS.Update(tOrdersAry) Dim tempTable As DataTable tempTable = <dsClassDef>.ORDERS.Clone ' The ORDER_ID field is an Autoincrement column. ' TURN IT OFF!!!!! tempTable.Columns("ORDER_ID").AutoIncrement = False ' Copy over all the data from the real (Details) DataTable ' (which includes the new, correct ORDER_ID value)... Dim tmpRow, tmpRow2 As DataRow For Each tmpRow In tDetailsAry tmpRow2 = tempTable.NewRow tmpRow2("ORDER_ID") = tmpRow("ORDER_ID") tmpRow2("CUSTOMER_ID") = tmpRow("CUSTOMER_ID") tempTable.Rows.Add(tmpRow2) Next ' Update the Database with the 'Added' records... yy = sdaOREDRDETAILS.Update(tempTable) //------------------------------------------------------ //------------------------------------------------------ One detail left to do at this point is call the AcceptChanges method for the -real- rows in the ORDERDETAILS DataTable. Since this is dependant upon your particular handling of the transaction, I do not include that code in this example, though I would suggest handling the INSERTS in a separate transaction and calling the AcceptChanges method for each added (detail) row rather than for the entire table after all updates, inserts, and deletes. In closing, I would just like to add that under normal circumstances I would not have bothered to comment on this problem. I have in this case because Microsoft has documented this situation to a fair degree of detail, but has done so incorrectly, ineffectively, and when consulting more than one source, in a conflicting manner. I paid good money to buy a MicrosoftPress book since they, by all rights, should be the absolute experts on the subject. I then added to my confusion by consulting the Microsoft website to clarify, only to find more wrong answers (though stated in a very matter-of-fact manner). I freely admit that I have never, and I mean never, really liked Microsoft. Mostly because of their business practices, but also because of the quantity of bugs and known problems within their software (which will be fixed in the next release for only $xxx.xx!!). When the company I work for decided to use .NET for a system re-write, I began investigating it, and to my own surprise, I was very pleased with what I found. For the first time in twelve years, I had something NICE to say about Microsoft. However, as with everything else from MS, once you get down to the details, the documentation ALWAYS works better than the actual software.

    - Flexible Data Provider Architecture Hello, I need advice on how to design flexible data handling for an app that meets the following general installation options: 1. data on local machine, single user, probably using Access or FoxPro 2. data on network, multi-user, client server, SQL Server or Oracle 3. data on web service using SQL Server and IIS The option chosen must be transparent to the client. Currently my design is based on separating the client app from the data provider. The client instantiates a class from a separate dll that handles communication between the client and the data - currently SQL Server. I figured that I would later expand data handling to other data sources through subclassing. While I haven't since ruled this out, I'm guessing that the web service version will throw a wrench into this approach. The question is how to provide elegant and transparent switching between data handling code for a flexible and growing list of data providers. I'm tempted to implement an intermediate "generic" wrapper class containing all the methods needed by the client. The wrapper class would then farm out the actual work to provider-specific classes based on the provider in use. Unfortunately, I have yet to work with web services, so anything I come up with at this point would be a guess. Any advice would be appreciated.

    - SQL Server 2000 Timestamp and Dataset Hi all I experience Problem when using SQL Server Timestamp attribute. I have a DataAdapter defined to use Stored SQL Procedure for select, insert, update and delete. When i fill the DataSet i also populate it with the SQL2K Server Timestamp. How can i pass the Timestamp value back in the Dataset or how is the correct definition of the Dataset for the Timestamp value. When i perform a update with the DataAdapter.Update Method the Update will fail if i have a statement like this in the Stored Proc: Update Table set Name = @Name where ID_Table = @ID and Tstamp = @Tstamp If is use the statement : Update Table set Name = @Name where ID_Table = @ID with no Timestamp the Update is well working. I guess that the Timestamp value is not passed in the Format needed. The DataAdapter is generated with the wizard. I'm using a typed Dataset. Do you have some suggestion / help ?

    - Accessing FoxPro Database using OleDB Hi, I am currently working on a project in which I need to interrogate a FoxPro database and present some results from the database in a web browser. I am using VS.NET 2003, Framework 1.1. I build a Select statement and then use the Select statement to query a table in the FoxPro database. The problem is, the query is taking a very long time to run from my .NET code. Running the same query from inside Visual Fox Pro is 20 times faster. Does anyone know what I can do from my .NET code to make the query much faster? The query string I use follows this pattern: SELECT * FROM myTable WHERE UPPER(myField) = myValue Thanks in advance Glenn Tag: how can I get the path for the error ORA-01458 Tag: 62658

    - SqlDataAdapter.Update replacing first row with second after update Hi, I have a WinForms app with a strongly typed dataset that contains two tables, FamilyMembers and ClassesTaken. For both FamilyMembers and ClassesTaken, I have a default value of -100000 for the AutoIncrementSeed with a step of 1. I am trying to simply use these default values temporarily, wait for the user to hit "save", post the changes to the database, and return the identity values into the appropriate columns (FM_ID, CT_ID). I have a datarelation mapped from FamilyMembers to ClassesTaken on FM_ID to FM_ID with an UpdateRule set to cascade and an Accept/Reject rule of none. (A FamilyMember may have 0 or more classes taken.) The problem is that when I add more than one family member, and then assign the FIRST family member entered to a ClassesTaken record, the DataAdapter is for some reason overwriting the first record in FamilyMembers with the second record. I have set the SqlCommand.UpdatedRowSource for the update and insert statement to UpdateRowSource.OutputParameters. This behavior does not occur when the 2nd or subsequent rows are assigned a "ClassTaken". For example: (PRE-UPDATE) FamilyMembers (FM_ID, First, Last) -100000, Jim, Smith -99999, Mary, Smith ClassesTaken (CT_ID,FM_ID,Class) -100000,-100000, English (POST-UPDATE) FamilyMembers (FM_ID, First, Last) 2, Mary, Smith 2, Mary, Smith ClassesTaken (CT_ID,FM_ID,Class) 1,1,English What is strange is that the data is inserted correctly into SQL, but the dataset is showing duplicate records for the FamilyMembers. When I set the UpdateRule to "NONE", this behavior does not occur, but I also lose the FM_ID foreign key update on ClassesTaken. Is there any explanation for this? I'm at wits end with this one.

    - Connection question In the course of using VS.net I have generally setup my connections by dragging a SQLDataAdatper to the form and going from there. However, I am at a point where I would like to begin connecting to the database and creating DataAdapters and DataSets via code. On a form I go into the ConnectionString property of a SQLConnection object and copy the values there. I suppose that I can just copy these values to my connection string that I create in code, but I can not. I have code that looks like this: Dim myConnection As New SqlClient.SqlConnection myConnection = New SqlConnection Try 'myConnection = "workstation id=P426;packet size=4096;integrated security=SSPI;data source=P426;persist security info=False;initial catalog=Corp" Catch ex As Exception End Try With the code above I get a squiggly under the "Workstation id = P426...." line and it says, "Value of Type String can not be converted to System.data.sql.connection" What do I need to do to write a connection string that is palatable to my code? What is the easiest way of doing this? Tag: how can I get the path for the error ORA-01458 Tag: 62621

    - One dataAdapter and two tables. Does it work? Hi all, I am using a dataapater, a dataset and an select sql command to retrieve data from two related tables using the following code: Dim da As New OleDb.OleDbDataAdapter("SELECT Materials.*, Material_Functions.fName FROM Material_Functions INNER JOIN Materials ON Material_Functions.ID = Materials.Function;", conn) Dim ds As New DataSet("DSMaterials") da.Fill(ds, "Materials") You cannot see it in the code but table 'Materials' and table 'Material_Functions' both have a field called 'fName'. For simple (one table) sql commands I had no problem binding textboxes to fields in the dataset using the following code: (Assume sql command is "Select * From Materials;") TextBox.DataBindings.Add("Text", ds, "Materials.fName") But this doesn't work any more. I checked the output window during run-time and all the fields are placed under one table (Materials) which is logical. I also noticed that the 'fname' field coming from the 'Material_Functions' table is named 'Material_Functions.fName', which is also logical. The question is when it comes to data binding what to I put in the third argument??? 'Materials.Material_Functions.fName' doesn't work. I know that I can use a second dataadapter to load the second table separately and set the relationship in the dataset manually, but I would prefer to do it in just one dataadapter (don't ask me why, because I don't know that either). So how do I work around it with just one dataAdapter? And if I should use 2 of them what is the advantage of that over the single DA?
