    - Get XML from typed dataset Hi, I was using Typed Dataset in VB.NET to generate XML file. I difined XSD file( named customer_order_info) to include three tables, let's say customers, orders and order_details. I also defined relationship between customers and orders, orders and order_details.( customerid is PK in customers, orderid is PK in orders, orderid and productid are PK in order_details). In my VB.NET code, I declared a variable as the XSD(customer_order_info), declared a adapter to populate it(some common routines to get dataset). the select command is a stored procedure which will retuen 3 recordsets. I also defined table mappings when I populated the dataset. After I got the dataset, I call ds.getXML to get xml file. I was able to get the file with correct content, but the format is wrong. For eample, the format should be as follows: <customer customerid=â??aaaâ?? name=â??billâ?? phone=â??123345456â?? > <order orderid=â??1011â?? customerid=â??aaaâ?? shipname=â??Du monde entireâ??> <order_detail orderid=â??1011â?? productid=â??tool1â?? quantity=â??12â??/> <order_detail orderid=â??1011â?? productid=â??tool2â?? quantity=â??20â??/> <order_detail orderid=â??1011â?? productid=â??tool3â?? quantity=â??30â??/> </order> <order orderid=â??1012â?? customerid=â??aaaâ?? shipname=â??Du monde entireâ??> <order_detail orderid=â??1012â?? productid=â??tool4â?? quantity=â??12â??/> <order_detail orderid=â??1012â?? productid=â??tool2â?? quantity=â??20â??/> <order_detail orderid=â??1012â?? productid=â??tool5â?? quantity=â??30â??/> </order> </customer> But I got : <customer customerid=â??aaaâ?? name=â??billâ?? phone=â??123345456â?? > <order orderid=â??1011â?? customerid=â??aaaâ?? shipname=â??Du monde entireâ??/> <order orderid=â??1012â?? customerid=â??aaaâ?? shipname=â??Du monde entireâ??/> <order_detail orderid=â??1011â?? productid=â??tool1â?? quantity=â??12â??/> <order_detail orderid=â??1011â?? productid=â??tool2â?? quantity=â??20â??/> <order_detail orderid=â??1011â?? productid=â??tool3â?? quantity=â??30â??/> <order_detail orderid=â??1012â?? productid=â??tool4â?? quantity=â??12â??/> <order_detail orderid=â??1012â?? productid=â??tool2â?? quantity=â??20â??/> <order_detail orderid=â??1012â?? productid=â??tool5â?? quantity=â??30â??/> </customer> Could anyone help me out?

    - Excel-like appearance in the datagrid I'd like to give my users the same "empty grid" look of an Excel sheet (at least an empty row to start with). I've thought to mimic this appearance by setting up an empty datatable bound to the grid (columns will be predefined) and then using AddNew to add the first empty row to the table. Is that the usual approach or can anyone recommend something better? Tag: logon failed on asp.net and crystal report Tag: 100491

    - Same question again - tables fro 2DBs Sorry, but I asked the previous question poorly. I have two SQL Server databases (on the same server) and I want to reference tables from both DBs in the SQL. I know that manually written SQL can reference tables in multiple databases by prepending the database name when necessary. However, we use the DataAdapter Configuration Wizard and Querybuilder for productivity reasons but it seems that this wizard will only allow connection to a single database withing a single data adapter. Is there a way to be able to include tables from multiple databases in the Querybuilder wizard? Thanks, T Tag: logon failed on asp.net and crystal report Tag: 100489

    - Can't save new row to table Can't save new row to table I'm trying to save a new row using the following code: It's a schema adapted almost exactly from one given me by Kevin Yu some time ago. One difference is the inclusion of the ID field. If I don't include it I get an error message. I also have an addhandler onCAIrowupdated. The msgbox in that gives the right answer for the table's ID = 0, since it would be the first entry. However, right after the msgbox I get an error. Message: You cannot add or change a record because a related record is required in table 'PointsOfView'. The line number indicated is intModified = daCAI.Update(tblCAI) Of the six fields in ComceptAssignmentInstances, four have 1 to many relationships with with table: TopicID, PointOfVew, ReportType, and ConceptID. This is an Access database. I carefully examined the relationship table, and PointOfView is identical with all the others. So I put in the following message boxes Both showed values 0, because I hadn't changed them, and the error message showed. The second time I changed the comboxes selected items and the save was successful. Two problems. The first is the known but of having to first move the selected value of of comboboxes to 1 and then back to 0. But where and how can I do it once I click the save button? The second problem is that the ID value in the saved table was -1. Since ID is an autoincrementing long integer, why didn't it have value 0? thanks, dennist685 Private Sub btnSaveC1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSaveC1.Click Try daCAI.Fill(DsCAI1, "ConceptAssignmentInstances") Dim tblCAI As New dsCAI.ConceptAssignmentInstancesDataTable Dim rowCAI As dsCAI.ConceptAssignmentInstancesRow rowCAI = tblCAI.NewConceptAssignmentInstancesRow rowCAI.ID = -1 rowCAI.TopicID = iTopicID rowCAI.BeginText = txtConceptText.SelectionStart rowCAI.ConceptID = lstConcepts1.SelectedValue rowCAI.ReportType = Me.cboRptTypeCncpt.SelectedValue rowCAI.PointOfView = Me.cboPOVCncpt.SelectedValue 'rowCAI.ReportType = Me.cboRptTypeCncpt.SelectedValue MsgBox("report type " & rowCAI.ReportType.ToString) MsgBox("point of view " & rowCAI.PointOfView.ToString) tblCAI.AddConceptAssignmentInstancesRow(rowCAI) daCAI.InsertCommand = New OleDb.OleDbCommand("INSERT INTO ConceptAssignmentInstances(ID, TopicID, BeginText,ConceptID,ReportType,PointOfView) values (?,?,?,?,?,?)", cnCAI) 'daCAI.InsertCommand = New OleDb.OleDbCommand("INSERT INTO ConceptAssignmentInstances( TopicID, BeginText,ConceptID,ReportType,PointOfView) values (?,?,?,?,?)", cnCAI) daCAI.InsertCommand.Parameters.Add("@ID", OleDb.OleDbType.Integer, 4, "ID") daCAI.InsertCommand.Parameters.Add("@TopicID", OleDb.OleDbType.Integer, 4, "TopicID") daCAI.InsertCommand.Parameters.Add("@BeginText", OleDb.OleDbType.Integer, 4, "BeginText") daCAI.InsertCommand.Parameters.Add("@ConceptID", OleDb.OleDbType.Integer, 4, "ConceptID") daCAI.InsertCommand.Parameters.Add("@ReportType", OleDb.OleDbType.Integer, 4, "ReportType") daCAI.InsertCommand.Parameters.Add("@PointOfView", OleDb.OleDbType.Integer, 4, "PointOfView") AddHandler daCAI.RowUpdated, AddressOf OnCAIRowUpDated Dim intModified As Integer intModified = daCAI.Update(tblCAI) Dim sOutput As String sOutput = "Modified " & intModified & " ConceptAssignmentInstances" Dim s As String = ControlChars.CrLf Catch ex As OleDbException If ex.Errors(0).SQLState = "3022" Then Else Dim errorMessages As String errorMessages += "Message: " & ex.Errors(0).Message & ControlChars.CrLf _ & "NativeError: " & ex.Errors(0).NativeError & ControlChars.CrLf _ & "Source: " & ex.Errors(0).Source & ControlChars.CrLf _ & "SQLState: " & ex.Errors(0).SQLState & ControlChars.CrLf _ & "StackTrace: " & ex.stacktrace & "The form will be closed" MsgBox(errorMessages) Me.Close() End If Catch ex As DBConcurrencyException MessageBox.Show(ex.Message & "StackTrace: " & ex.stacktrace, "Update failed!", MessageBoxButtons.OK, MessageBoxIcon.Error) Me.Close() Catch ex As Exception MessageBox.Show(ex.Message & "StackTrace: " & ex.stacktrace, "Update failed!", MessageBoxButtons.OK, MessageBoxIcon.Error) Me.Close() End Try Me.cnCAI.Close() End Sub Tag: logon failed on asp.net and crystal report Tag: 100479

    - Connection String Machine Independent. Hi there, I've been researching on the diferent newsgroups to find out how to do this, but no luck so far. I'm developing a client/server windows application with VB.NET, MSDE is my backend database. This is sample connection string to connect to my server: data source=MACHINE_NAME\MSDE; initial catalog=DatabaseName; user ID=sa;password=sa Now, when I distribute this application, the Server will have to be installed in one machine in the LAN, now the connection string it's hardcoded right now to look for a specific machine name and the instance name. So, how can I build, if it's possible, the connection string machine independent? Thanks very much, Manny Tag: logon failed on asp.net and crystal report Tag: 100467

    - How to resolve "General Network Error"? I'm getting the following message trying to update a SQL Server table: "General network error. Check your network documentation." I'm using stored procedures via a SQL data connection from within a .Net windows application. The application producing the error, reads a table from the server, then proforms a series of updates, deletions and insertions locally to a DataSet. After all processing is completed, the data is written back to the server using the Update(dataset, "table_name") method on the DataAdapter. The Update method is called 3 times, once for all updated rows, once for all inserted rows and once for all deleted rows. Currently, I read and update 3 tables in seperate datasets. 2 tables work and the 3rd does not. How can I get resolved this issue? Tag: logon failed on asp.net and crystal report Tag: 100464

    - ado.net exception from raiserror In a couple of stored procedures (SQL Server 2000) im doing: raiserror('aaa',16,1) return 1 My understanding was that this should throw an exception in my C# code. But sometimes it doesn't (I have to manually check the return value parameter). Can anyone explain why? Is there a difference in behaviour between SqlCommand.ExecuteNonQuery and ExecuteReader (or SqlDataAdapter.Fill) in this regard? The situation where I've noticed no exception is being thrown is when I'm calling adapter.Fill(), and the sproc has already returned a resultset (but later on in the sproc code it detects an error). Maybe the presence of a resultset prevents an exception being thrown? Thanks, John Tag: logon failed on asp.net and crystal report Tag: 100448

    - Better way to build results? (Relative newbie) Hello, Undoubtedly this answer is in front of my nose, but I can't figure it out or find it anywhere. Using VB.NET, Access database. I have successfully built a series of nested queries that return results from three interrelated tables, reading the results into datareaders. I can iterate through the three datareaders and build the results that I want, but I suspect there are more efficient ways to do what I need. The only way I have been able to get this to work is by establishing one connection for the first query, and then in a nested loop keep making connections to satisfy the second query, and within that loop there is another loop that keeps making connections to satisfy the third query. This works fine on my very small test database, but I know users will have much larger ones. I can't use UNION, because the tables have differing numbers of fields. Let's say I have three tables: Neighborhoods, Houses, and Residents (not my real database!). Neighborhood.nID = Houses.nID and Houses.hID = Residents.hID. The trick is that I might not have houses for every neighborhood, and I might not have residents for every house. But I need to get all the neighborhoods, even the ones without houses, and I need to get all of the houses, even the ones without residents. Conversely, every resident has to have a house, every house has to have a neighborhood. So my simplified code is: Establish first connection Get all the neighborhoods Read the first neighborhood Build a node for a TreeView Establish/reestablish second connection Get all the houses in that neighborhood Read the first house Build a node for a TreeView Establish/reestablish third connection Get all the residents in that house Read the first resident Build a node for a TreeView Loop Close third connection when we've found all the residents for that house Loop Close second connection when we've found all the houses for that neighborhood Loop Close first connection when we've found all the neighborhoods Any and all advice gratefully received.

    - Adding columns to SQL Server tables dynamically Hi, I'm writing a routine which queries a table in a mySQL database and then adds records from it into a SQL Server 2000 database - pretty easy stuff. Problem is, that the mySQL table may have additional columns every time I query it. I can easily use the Columns collection of both tables to see if there is a new column in the mySQL table which isn't in the SQL Server table, but what's the easiest / most efficient way to add a new column to an existing SQL Server table, given that I know the name and datatype of the column to be added? Would it be to pass some sort of "ALTER TABLE..." SQL into an SQLCommand object, or is there a better way? Any assistance gratefully received.

    - DataSet, Relation, IsNested and WebService Hi all, If I want to provide a typed dataset from a webservice and if that dataset has relations that are nested (isNested=True), then the relations(keyrefs) are not available in the XSD that is offered. If I set IsNested to false or default, then it is included in the XSD. Is this a bug or by design? Corno Tag: logon failed on asp.net and crystal report Tag: 100431

    - Converting from DataColumn to OleDbType for Analysis Services 2005?? Its been posted before, but I've not found a satisfactory answer. Environment: Dot-Net 2.0 beta, with Analysis Services 2005 beta. DbDataAdapter produces DataColumns from its FillSchema method which give me all sorts of information about the data type of the column. AMO, the API for Analysis Services 2005, requires me to give an OleDbType when I set up a foriegn key in a fact table and when I make an Attribute. (I'm using metadata as a starting point to scan a data warehouse and build the dimensional model programatically. Think of it as a form of Intellicube, but especially taylored to the structure of our data warehouses feeding off our existing metadata.) The thing is. I've used DbDataAdapter to FillSchema() to get the underlying field types in the tables. It should _know_ what data type is there as its just told me. I suppose the problem is that DataTable class being generic can't know anything about specific databases, but it would be nice if there was a method somewhere to take a DataColumn and get the XXXDbType from it. Analysis Services already knows the data type, as it's got a Data Source View. I've presumably already told it once when I defined the schema by passing in the DataSet that defined it - the DataSet made using FillSchema. Or have I? I'm building up a model that presumably hasn't been committed yet, so presumably the problem is that there's no way (even though I've given it a Connection String) for it to go to the database and find out what it needs, and its not willing to wait until commit time to work it out? Can I assume that the DataColumn doesn't have enough information in itself? Therefore the Data Source View is, at that time, incomplete, and I have to add the information myself from an external source? If thats the case - it's not nice. Also, as an aside, why (I'm following Microsoft's sample code) am I using an OleDbDataType with an SQLServer database? Thanks - Richard Tag: logon failed on asp.net and crystal report Tag: 100428

    - Viewing large amounts of data We have a data management application writen in Delphi. This app shows all tables in the database, and display all data in a given table in a datagrid. We are using an ODBC connection for this. This functionality is not unlike what is seen in e.g. Enterprise manager. Now even with 400K of rows, this datagrid is "filled" is mere seconds. I am aware that the underlying dataset only retrieves a subset of rows, and dynamically retrieves and unloads rows as needed, thereby giving an illusion of retrieving the entire table. We are now moving to .net and I find myself having a great deal of difficulty getting the same functionality out of ado.net. The ODBC components we are using in our Delphi app is connected whereas ado.net is disconnected. What I basically need is to retrieve say 100 rows at a time, and dynamically unload and retrieve new rows and filling them into a datagrid as the user scrolls back and forth through the datagrid. How do I achieve this? Please dont lecture about filtering and whatnot. This is the functionality we need. -- Thomas Due Posted with XanaNews version 1.16.5.2 "If you can't convince them, confuse them." -- Harry S.

    - deleting rows in one-to-many relationship Dear Ng, I have a 1(master table) : n(first child table) : m(second child table) relationship in my sql server and strongly typed dataset. Now I locate the corresponding row in the master table. DataAccessControl.DocumentTemplateRow rowTemplate = tblTemplate.FindBydocumentTemplateId(templateId); Then i request all child rows: DataRow[] rowsToDelete = rowTemplate.GetChildRows("DocumentTemplateDocumentField"); Then I want to delete all child rows in the child tables: foreach (DataAccessControl.DocumentFieldRow row in rowsToDelete) { tblFields.RemoveDocumentFieldRow(row); } dac.updateDataAccessLayer(); The delete rules of both relations (from the master to the first child and from the first to the second child) is set to cascade (in the database and in the dataset). But if I execute the code, just the rows in the second child table are deleted. What do I do wrong? If I use additionally the row.delete() command foreach (DataAccessControl.DocumentFieldRow row in rowsToDelete) { row.Delete(); if (row.RowState == DataRowState.Deleted) tblFields.RemoveDocumentFieldRow(row); } dac.updateDataAccessLayer(); I'll get a DBConcurrencyException! What is wrong? What I want to achieve is that the master record is kept and all child records are deleted.

    - Trouble with OleDbDataAdapter Hi there, I am trying to display information from Active Directory using a DataGrid. Now, I know MS have put out the System.DirectoryServices classes to make this easy. But if you just want to query and display, it seems an easier path is to use the AdsDsoObject provider with OleDb, and get back a DataTable, pour into a DataView, bind to the DataGrid, voila! At least, that's the theory. The main driver is that trying to bind a SearchResultCollection to a DataGrid doesn't yield very satisfactory results, and that's the only useful class in the DirectoryServices namespace that implements ICollection and IEnumerable. The problem is, if I manually construct a DataTable with dummy data, pour into a DataView, bind to DataGrid and display then I see exactly what I would expect. If I setup an OleDbDataAdapter, query the AD, fill a DataSet and serialize to XML I see what I would expect. If I setup an OleDbDataAdapter, query the AD, fill a DataTable, pour into a DataView, bind to the DataGrid and display, I get: System.Web.HttpException: DataGrid with id '' could not automatically generate any columns from the selected data source Here is the source for Page_Load that generates the last result: string ldapString = "<LDAP://DC=acme,DC=com>;(&(objectClass=user)(objectCategory=person));cn,distinguishedName;subtree"; string connstr = "Provider=ADsDSOObject;User ID=acme\\Administrator;Password=notthispassword"; OleDbConnection conn = new OleDbConnection(connstr); OleDbDataAdapter da = new OleDbDataAdapter(ldapString, conn); DataTable dt = new DataTable("Table1"); da.Fill(dt); DataView dv = new DataView(dt); dg1.DataSource = dv; dg1.DataBind(); Now, I'm fairly new to all this, but I've spent a good couple of days butting up against this one. The only checking I haven't really done is using OleDb with a different provider and seeing if it is a general problem. The main reason I haven't done that is that I can see the data there if I use an alternate means of accessing it! So, any ideas?

    - "Cannot create a child list for field MyTable" I'm having a frustrating problem trying to set up a master-detail relationship between 2 datagrids. I've used DataSets extensively before, but only in code and basically only in a disconnected state. Now as I try to set up this simple master-detail thing, I'm having problems. I have about 6 tables in a SQL Server 2000 database. All tables have single field primary keys, and I've created appropriate relationships betwen the tables in SQL Server. In VS 2003, I've created a SQLDataAdapter for each table, that interacts with the table via stored procedures created by the SQLDataAdapter wizard. I then used the "Generate Dataset..." functionality of one of the data adapters to autogenerate dataset that included all 6 tables (i.e. it was based on all 6 data adapters). So far so good. In the DataSet schema editor, I created relationships between the datatables to mimic the relationships in SQL Server. This seems to go ok, and when I "Preview DataSet" from the schema editor, all seems ok - including the relationships. I also have a WinForm that has 2 DataGrids on it. Both DataGrids have the DataSet I created as their DataSource. When I try to list the DataTables in the DataGrid.DataMember property so I can set up the DataGrids for the master-detail, I the the error, "Cannot create a child list for field MyTable", where 'MyTable' is one of my DataTables in the DataSet. If I remove all of the relations from the DataSet, and save the .xsd schema a few times (moving the datatables on the designer between saves so there's something to save), the error will go away - but then I have no relationships. So, I re-create the relationships in the DataSet schema editor, and I start getting the error again. Sometimes I don't get the error until I have more than one relationship, and sometimes by moving the datatables on the schema designer and re-saving the dataset schema a few times, I don't get the error - even when the dataset has 2 relationships. It seems some code is getting corrupted somewhere. I've tried restarting VS, and I've rebooted my machine. I've also deleted the DataSet and created it again from scratch. The same thing happens. When running my project, I can successfully fill my DataSet from the DataAdapters, but I get the same error when I try to set the DataMember property of one of the DataGrids in code. What's going on?

However, when I move the solution to another PC and try to run it, it fails saying "Login failed for user DEVONE\Guest'. DEVONE is the name of the machine where I developed the application, which is running SQL Server 2000 Developer.

    - GetChanges false positives, How to avoid? I was curious if anybody know of a way to avoid false positives while using the GetChanges method. In most of my updateable aspx pages I have text/ddl/checkboxes that are populated from the existing data that the user can change, then hit the save/update button. When the save/update button is clicked the dataset is updated from the controls values regaurdless if the values in the controls have changed or not. Such as ds.Table1.Col1 = TextBox1.Text; // set whether text has changed or not. ds.Table1.Col2 = TextBox2.Text; The problem arises when a user hits the save/update button without changing anything on the page. This means that all the values in the dataset get set to exactly what they were before; however, the GetChanges returns rows with no real changes in them. Take the following code. The last GetChanges always returns 1 row even though no values in the row have changed. Dataset1 ds = new Dataset1(); Dataset1.UsersRow r = ds.Users.NewUsersRow(); string s = "asdf"; r.UserName = s; r.UserID = 1; ds.Users.Rows.Add(r); ds.AcceptChanges(); DataTable dt = ds.Users.GetChanges(); if(dt != null) Console.WriteLine("# of changed rows " + dt.Rows.Count); ds.Users[0].UserName = s; // change the value to exactly what it was. dt = ds.Users.GetChanges(); if(dt != null) Console.WriteLine("# of changed rows " + dt.Rows.Count); Any help is appreciated, EntDevGuy Tag: logon failed on asp.net and crystal report Tag: 100388

    - How to effiently load many, many SQL records I have a need to effiently load millions of fairly small records into SQL Sever 2000. I have some financial data with many, many observations (one set has 37 million records) and I need to get it into a SQL server. I create a comma separated variable (CSV) file using a VB.NET program acting on the raw data. I have tried importing it into SQL Server using DTS import, but it says that it completes after about 18 million records, with no error. Using Visual Studio 2004 VB, I wrote a windows program that uses a SQL dataadapter to the table I want to insert records in, set the field parameters to the generated SQL insert command and then call ExecuteNoQuery to insert each record. This process works, but is seems to take forever to create a lot of records this way. I am fairly well versed in VS 2003 and VB.NET, but I am new to using these tools to load so many records. I must be doing something wrong or not using the appropriate technique to do this. Any help will be appreciated. Thanks!

Dim cn As New OdbcConnection("Driver={Microsoft Text Driver (*.txt; _ *.csv)};DefaultDir=d:\websites\jpg\dataimport;") Dim cmd As New OdbcCommand ("select * From cfr.csv") Dim myreader As OdbcDataReader cn.open() cmd.connection = cn myreader = cmd.executereader() response.write("<table>") While myreader.read() response.write("<tr><td>" & myreader.getstring(0) & "</td><td>" & _ myreader.getstring(1) & "</td><td>" & _ myreader.getstring(2) & "</td></tr>") End While response.write("</table>") cn.close() It outputs the following: 2004-12-01 00:00:00 31.0000 10 2004-12-01 00:00:00 32.0000 15 2004-12-01 00:00:00 33.0000 20 2004-12-01 00:00:00 34.0000 25 2004-12-01 00:00:00 35.0000 30 It converted the second field to a numeric value. I can get it to treat the field as character data if I put the values inside quotes but I don't have control of this file, it's delivered to me from a third party as is. Is there anyway to get it to read the data as plain character data without modifying the file? --Buddy Tag: logon failed on asp.net and crystal report Tag: 100360

    - DateTimePicker problem with .AddNew Hi! My Windows Form contains DateTimePicker to show date-type data from DataTable. Because application need to be able to save "no date" ie. NULL into database table, I solved it like way... ("dtpRepaired" is DateTimePicker-control) dtpRepaired.Checked = Not IsDBNull(dt.Rows(cm.Position)("Repaired")) If dtpRepaired.Checked Then dtpRepaired.Value = Date.Parse(dt.Rows(cm.Position)("Repaired").ToString()) End If Private Sub dtpRepaired_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles dtpRepaired.TextChanged dt.Rows(cm.Position)("Repaired") = IIf(dtpRepaired.Checked, dtpRepaired.Value, DBNull.Value) End Sub ...because I didn't succeeded to do this like this way bounding it directly to the DataTable... 'dtpRepaired.DataBindings.Add(New Binding("Text", dt, "Repaired")) This is almost working fine, but it occurs an error after cm.AddNew when trying to change dtpRepaired-controls value or Checked-state. Error message is: "There is no row at Position 5.". I understand this why, but don't know how I could solve to make it possible to "add new" and make it possible to edit dtpRepaired too without this problem. Any succestions? Is it really impossible to bound DateTimePicker-control to DataTable, and make it possible to change date in DataTable to "NULL" ? Hopefully you understand my problem with my poor english, I'm finnish :) -- Thanks in advance! Mika Tag: logon failed on asp.net and crystal report Tag: 100358

    - DataSet, new row and default values ? When I add a new row to a DataSet that was filled with info from a database the new row does not get the default values defined in SQL Server, how do I accomplish this seemingly simple task ? I don't want to have to fill in the default values in the row first, I want it to understand the defaults set in the database and fill it automatically as you would expect it to. Thank you PL.

    - Best aproach to update DataAdapters with XML-Data Hi all What's the best aproach to import xml-based data into an oracle 9i database with ado.net DataAdapters, when the data is in an xml-file? The operations should insert new rows and update changed rows. Does ado.net provide some automatisms for this or do i have to do this with functions written myself? Is there anywhere some example code? Thank you Adrian Tag: logon failed on asp.net and crystal report Tag: 100347

Very likely, aspnet local windows account (network service on windows 2003)
has no NTFS privileges on mdb file and its folder.

That is right .. that is probably what the problem is.

I want to add that Crystal has the bad habit of storing your username
password in the .rpt file itself. A much better way would be to create the
rpt, and then use a strongly typed dataset xsd to generate the fields, and
then bind it with a dataset - that way you don't run into these issues.

Again personal opinion - I feel .rpt based crystal in this way isn't very
well suited to web purposes (unless you spend lotsa $). Check out
datadynamics activereports for instance - cheaper and arguably has some
downsides but still a good (and cheap) product suited for web.
