    - some problem in System.Data with delete Hi to all I try to delete row from DataTable. When I make row.Delete sometimes I get this exception System.ArgumentOutOfRangeException I trace a little bit the problem and I think found something When I make delete in DataTable is invoked RecordStateChanged which in Turn meke this int i = LiveIndexes.Count; and then for (int j = 0; j < i; j++) { if (record1 != -1 && record2 != -1) { ((Index)indexes[j]).RecordStateChanged(record1, oldState1, newState1, record2, oldState2, newState2); } ... From here we see that this method calls RecordStateChanged in System.Data.Index and some times the LiveIndexes.Count is changed, but i is unchanged and here comes the problem If in the beginning i = 21, after this call LiveIndexes.Count = 20 , but i is still 21 and it make access by index 20 which course exception. I think that because System.Data.Index. RecordStateChanged fire event OnListChanged which in turn can change indexes ArrrayList. Can somebody help to resolve the probem?

    - VB.NET Retrieving Identity form MSSQL2000 without using stored procedures Hello! I have a problem. I'm using a dataset in VB.NET with multiple tables with relations between them. I would like dataset to update to all related tables with right identity, when certain record is added. The problem is that I don't know how to do it, when I'm not using stored procedures. I found an article in which OnRowUpdated event of the dataadapter is used. On this event ExecuteScalar method of the oledbcommand object is called to retrieve "@@Identity" http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/htm l/cpconretrievingidentityorautonumbervalues.asp But this example was for Access 2000 database. I tried to translate it for MSSQL 2000 but ExecuteScalar always returns null. In the same article there's an example which calls a stored procedure in a insert command. In that case everything is working perfectly, all child tables in dataset are automatically changed. Does anybody have any idea how to solve this? Regards, Taras Tag: Unecessary spaces in table.

    - Basic Question - But is Stopping me... any help? how to add items and update the index of the relationship table automatically? A sample of the problem : I have 2 tables with a relationship n..n so this means that the relationship is also generating a table so what kind of code I can use to do this. table 1 has the name of the persons : table 2 has the car that this person have... Note that I already have the peoples name filled with some records. first table has a PK let's call table1_rowid second table has a PK ... table2_rowid then the relationship m to n is generating a tbl1_tbl2 where I have two fields table1_rowid and table2_rowid When I'll add a new record in the table2 for the person that has the table1.rowid =1 what is the code that I can use to automattically fill the necessary information in the relationship table tbl1_tbl2?????? No doubt that exist some code to that automattically in the new ado.net or regular oledb.... objects in the DOTNET??? Any idea, to make my life easier? Tag: Unecessary spaces in table. Tag: 66043

    - "Generate Dataset" for custom data provider Hello, my company offers a set of ado.net components for its own database format and we want to respond to the general "Generate Dataset", "Preview Data" and "Configure Data Adapter" commands in the menus. In Visual Studio 2002 we had found a dirty trick to enable those commands but this doesn't work with VS 2003 anymore. The question now is whether there is now an official way to support those commands for custom data providers. Or has somebody found another way to activate them?

    - Filling a DataSet from a sql query against a XML schema Hi I'd like to know if it's possible, with an OleDbProvider, to fill a dataset from a sql squery against a XML schema. For exemple, i have this OleDbCommand : SELECT computer.name, processor.frequency, soundCard.model FROM computer INNER JOIN processor ON computer.processor_id = processor.id LEFT OUTER JOIN soundCard ON computer.soundCard_id = SoundCard.id After I use an OleDbDataAdapter to fill a dataset whose name is "computers". And I want to have to get the Xml data of this dataset. The result i want (by getting Xml) is <computers> <computer> <name>My Computer</name> <processor> <frequency>3Hz</frequency> </processor> <soundCard> <model>16 Bits sound card</model> </soundCard> </computer> </computers> But I have : <computers> <computer> <name>My Computer</name> <frequency>3Hz</frequency> <model>16 Bits sound card</model> </computer> </computers> I tried to load a schema into the dataset with ReadXml method but it seems that it doesn't work after the oleDbDataAdapter Fill method. I tried Microsoft SQLXML but it's still incomplete and very slow. So If someone knows if the thing i want to do is possible, please answer. Thanks Monorom SARIN Tag: Unecessary spaces in table.

    - Two DataGrids on One Form? Could be simple solution, but I can't findcontrol !!! I have the something like the following data structure: Users users_ID, orgs_ID, users_email, users_password, etc. Orgs orgs_ID, orgs_name, orgs_description, etc. I have a single form with two datagrids. I have loaded one dataset with two tables. There is only a single record at any time in each of the tables in the bound dataset. I bind the first datagrid to one datatable, and the second datagrid to another datatable. Both datagrids seem to populate just fine in edit mode, but... My UPDATE routine is fired on the update command of the first user_profile datagrid. SO THE PROBLEM IS: I can't findcontrol for the org_id in the second datagrid. The key issue here is the need to easily enable additional records to be added to the second datagrid, to enable the registration of different orgs. Anyone know about using multiple datagrids (not necessarily nested) on the same page? Just to prove I have NO idea what I'm doing, here's some of my code my code (simplified)... CODE SNIPPET Private Sub user_profile_update(Sender As Object, E As DataGridCommandEventArgs) If page.isValid Then Dim main_email As TextBox = e.Item.FindControl("main_email") Dim main_password As TextBox = e.Item.FindControl("main_password") Dim org_id As DropDownList = CType(FindControl("org_id"), DropDownList) data_set = load_user_data() Dim data_table as String data_table = "main_identity" If data_set.tables(data_table).Rows.Count > 0 Then With data_set.tables(data_table).Rows(0) .Item("main_email") = main_email.Text .Item("main_password") = main_password.Text .Item("org_id") = org_id.selecteditem.value <<<<<< ERROR ERROR System.NullReferenceException: Object reference not set to an instance of an object.

    - dataAdapter'rs command statements Do I need to fill all the 3 commands ( InsertCommand, DeleteCommand and UpdateCommand), even though I'm using only one of them ?

    - SqlDataReader recordsaffected Hi. Just reading about the sqldatareader object I am confused about the recordsaffected property. The example on the help docs use a procedure with some inserts and a select. Can I use a datareader object to run sql commands that does not return records? What is the advantage of using a datareader.recordsaffected instead of command.executenonquery, since the later also can give me the records affected?

    - Trouble clearing SqlParameters from my Command object (note - sorry for the crosspost - I sent to .vb thinking i was sending to .adonet). I implemented a very small, basic data access layer for my web application. It works just fine, except for this one bug. One of my methods returns an abstracted dataset. To accomodate X number of input parameters, I created a function signature that accepts a ParamArray of SqlParameters as well as the name of the stored proc. In the body of the function I loop through the param array and append each object to the Parameters collection of my Command object. The problem comes up when I try to append a SqlParameter object that I have already used in a previous call, that is also an argument for the next stored procedure. For example, I have: dim objParam1 as New SqlParameter("@userid", intUserid) dim objDS as DataSet objDS = objDAL.GetDataSet("storedprocname", objParam1) ' do some stuff with the dataset, now try a new query, different proc, same parameter objDS.clear() objDS = objDAL.GetDataSet("anotherprocname", objParam1) The error returned is something like "There is already a parameter named objParam1 in the SqlParametersCollcetion. Prior to adding each parameter, I check its count and, if greater than 0, remove each item before appending the new params. In debugging the count is always 0, so how can there be an SqlParameter object in its collection? ' create our command object with the passed in ProcedureName. ' and sqlparameter object. Dim objCommand As New SqlCommand(ProcedureName, Me.Connection) Dim sqlParam As SqlParameter objCommand.CommandType = CommandType.StoredProcedure Me.LocalCommand = objCommand If objCommand.Parameters.Count > 0 Then ' in case any parameters are hanging around, clear them out For Each sqlParam In objCommand.Parameters objCommand.Parameters.Remove(sqlParam) Next End If objCommand.Parameters.Clear() ' add the parameters passed in from the ParamArray ' into the command's parameters collection. For Each sqlParam In DataParameters sqlParam = objCommand.Parameters.Add(sqlParam) ' ERROR THROWN HERE Next What element am I missing please? This has me bending my brain pretty badly.

    - SqlDataAdatper Bug? I am new to .Net but have been unable to find anything about this in the newsgroups. Using C# and the following SQL stored procedure in my SqlDataAdapter: CREATE PROCEDURE HouseholdNextPrevious @PassedName varchar(150), @Direction varchar(4) AS Set NoCount on if @Direction = 'down' /* next household */ begin SELECT TOP 1 BuildingId, LabelName, Street1, Street2, City, StateProvince, Zipcode, Country, Phone, PhoneNote, Household.CellPhone, Fax, NoNewsletter, NoAppeal, NoCalendarAnnouncement, NoFlyer, Household.InactiveId, FirstConnectionId, Salutation, ICodeId, IncomeId, PrimaryContactId, Household.Note, Household.LastEditDate, SortName = isnull(LastName + ' ' + FirstName + ' ' + isnull(MiddleInitial,'') + Convert(varchar(40),Household.BuildingId),'aaaaa' + Convert(varchar(40),Household.BuildingId)) FROM Household LEFT OUTER JOIN Individual on IndividualId = PrimaryContactId where (isnull(LastName + ' ' + FirstName + ' ' + isnull(MiddleInitial,'') + Convert(varchar(40),Household.BuildingId),'aaaaa' + Convert(varchar(40),Household.BuildingId))) > @PassedName order by SortName asc end else /* previous household */ begin SELECT TOP 1 BuildingId, LabelName, Street1, Street2, City, StateProvince, Zipcode, Country, Phone, PhoneNote, Household.CellPhone, Fax, NoNewsletter, NoAppeal, NoCalendarAnnouncement, NoFlyer, Household.InactiveId, FirstConnectionId, Salutation, ICodeId, IncomeId, PrimaryContactId, Household.Note, Household.LastEditDate, SortName = isnull(LastName + ' ' + FirstName + ' ' + isnull(MiddleInitial,'') + Convert(varchar(40),Household.BuildingId),'aaaaa' + Convert(varchar(40),Household.BuildingId)) FROM Household LEFT OUTER JOIN Individual on IndividualId = PrimaryContactId where (isnull(LastName + ' ' + FirstName + ' ' + isnull(MiddleInitial,'') + Convert(varchar(40),Household.BuildingId),'aaaaa' + Convert(varchar(40),Household.BuildingId))) < @PassedName order by SortName desc end When I generate the dataset based on the above stored procedure, it constructs two tables (HouseholdNextPrevious and Table1) in the dataset which have identical columns. If I use an OledbDataAdapter, it only contructs one table in the dataset (HouseholdNextPrevious). Any insight as to why this is happening? Thanks, Tag: Unecessary spaces in table. Tag: 65995

    - Shouldn't An Exception Be Thrown - Establishing a Primary Key Hello, I was setting the primary key on a table which was a collection of 3 columns. I mispelled the name of the second column when I built the array of collumns when I created the array of collumns for the primary key. When I used the "dt.primarykey(myArrayOfKeys)" no exception was thrown, and rather then the primary key being a set of 3 columns, it was only a single column. When you make this type of mistake when setting foreign keys, that process throws and exception.

    - CommandTimeout property Clarification I have a stored proc that runs and calls others and sometimes the process runs for 3 to 5 minutes depending on traffic. ASP.NET - ADO.NET - Sql 2000 Code - dim cmdV as sqlcommand = new sqlcommand("ValidateUpdatePrograms",cnOAP) cnoAP.Open() cmdV.ExecuteNonQuery() cmdV = nothing cnoap.Close() Does the CommandTimeout property refer to the time to wait until a command starts processing or does it refer to how long a command can process before it is considered overdue? If it is the second case will sql actually stop in the middle of processing? Currently I am getting Application Unavailable in the browser after the Machine.config setting responseDeadlockInterval has been exceeded. I will set this higher. But I am wondering if sql is still processing and the web server times out, will sql continue processing until it is done? I have tested and it seems like it does. It seems like it will also stick with the command until it is done no mater how long it takes. I have not set the CommandTimeout. I am trying to figure out how to make sure sql doesn't stop. Thanks!

I am using the performance monitor to check the # of connection pools as well as the # number of pooled connections. When I start the app and the user logs in a pool & connection is created and all is well. However when I shut down the app the pool does not go away. Then if I start the app again another pool and connection are created and soon, and so on?? Does anyone have any idea how I should deal with this? Should the pool created by the app be detroyed when the app is no longer in memory. By the way I am using CLR .Net Data for the specific app, not _global. Tag: Unecessary spaces in table. Tag: 65983

    - DataTable schema changes I need to handle dynamic changes to a table's schema, even when there is already data present. It appears that the only thing supported by DataTable is to remove a column so I am pulling all the data out into a 2D array, performing my manipulations on the raw data, and then clearing out the table's Rows and Columns collections and attempting to recreate them. Basically, Rows.Clear(); Columns.Clear(); RebuildColumns(/*...*/); RebuildRows(/*...*/); Where I rebuild the columns from a separate list of schema parameters that I have available and then rebuild the rows from the 2D array of raw data that I originally pulled from the table. For a simple test I am trying to remove the third column from a four column table (something that I suppose I could have done simply via Columns.RemoveAt, but am trying this way as a test). The problem is that when I'm adding the rows back, I'm getting an exception thrown on adding the second row: System.IndexOutOfRangeException "Cannot find Column 3" System.Data.DataTable.InsertRow Can anyone shed some light on this for me?

    - The same table (types) cannot be the child table in two nested relations. I have a Schema describing an XML feed i'm receiving. The problem is, when i load it i get the above error. In this schema i have several fields describing an article. Two of these fields(tables) are called videos and sounds. They both contain a complex type (table) called Types which contain from 0-unbound number of "type" elements. So the case is. Both the sounds and the videos nodes have types/type nodes, which won't map to my DataSet. I don't think i can get the xml provider to change the format, but is there any way i can add something to the schema to allow the "same table" twice?

    - RowState Issue In using a datagrid, when I modify the second row in the grid, the first row is also taking on a rowstate of modified, even though it has not been touched. I am sure of this, as checking rowstate prior to modifying the second row shows the first row to be Unchanged. Anyone have any clues about this issue? Thanks. JT Tag: Unecessary spaces in table.

    - Dataset and Bindings HI All, 1) I open up a dataset (declared at the module level) 2) I get the data with the .FILL using the DataAdapter 3) I update a DataGrid RecordSource property to the DataSource 4) I update the DataBindings of a Text box to one of those fields. Now, the data loads into the datagrid and the text box just fine. When I move around in the datagrid, it changes the value in the text box. Now, how do I change the current record using code? I've tried using the: me.bindingcontext(dsCustomer, "dtCustomer").position Modifing this values does not modify the control on the screen and changing the record position on the screen does not change the bindingcontext.position value. Any help is appreciated. Dave. Tag: Unecessary spaces in table. Tag: 65907

    - DataView Filter Not working I am using the following code to filter a DataView and then put the dataview back into a DataSet. I've verified that strFilter contains 683 values. The dataview initially has 1306 records before the filter. However, the resulting dataset that comes out has all 1306 rows. How is this possible since I'm filtering on 683 unique values? I'd appreciate any help -Tim //create a dataview for the dataset //DataTable oDT = oDS.Tables["Results"]; DataView oDV = new DataView(oDS.Tables["Results"]); DataTable oDT = new DataTable(); try { if(strFilter != "") { //filter the dataview with the previous work ids oDV.RowFilter = "WorkID IN (" + strFilter + ")"; } } catch(Exception err) { Response.Write("Error: " + err.Message.ToString()); } //Convert the DataView back to a DataSet oDT = oDV.Table.Copy(); oDS = new DataSet(oDV.Table.TableName); oDS.Tables.Add(oDT); Tag: Unecessary spaces in table.

    - DataAdapter update method fails Hi. I got a problem with the OleDbDataAdapter object in .Net. The case is: I fill a dataset with data from an XML-file. This works fine. I then want to store the data into a database. This also seems to work fine. The problem ouccurs when I try to update the data in the table. If I read the same XML-file into the dataset and perform the Update method of the dataadapter it throws this Exception: ORA-00001: unique constraint (SOME.TABLE) violated Source code: ################################################################ Dim cb As New OleDbCommandBuilder(OleDbDataAdapter1) DataSet1.ReadXmlSchema( _ "H:\temp\foo.xsd") DataSet1.ReadXml( _ "H:\temp\foo.xml") OleDbDataAdapter1.Update(DataSet1) Catch ex As Exception Console.WriteLine(ex.Message) End Try ################################################################ It seem to me that the dataadapter trys to do an insert and fails because there already is a row with the same values in the table. Anyone got a clue how to solve this? Lars Tag: Unecessary spaces in table. Tag: 65894

    - How to lock a table or a database using VB.NET and ADO.NET with SQL Server 2000? Hi, I have a few question regarding Locking question. I'm using VB.NET and my Database is SQL Server 2000. 1) Certain part of my application, I need to lock the whole table to prevent other user from using it, how should I lock it to prevent user access the table. 2) There's one part of my application, I need to lock the whole database (block user) when I want to transfer the records from the working table to the storage table then release the lock after I'm done. How should I go about doing it? Regards Vanessa Tag: Unecessary spaces in table. Tag: 65891

    - renaming an element in a schema/dataset I read some xml data through a stream, and pass it to a dataset for it to read. First i initialize the dataset with an xml schema. The schema matches the data i get from the stream, but i want to change the name of some of the columns. Normally i would add some mappings to the dataadapter, but since i'm not using a dataadapter (there is no database involved - i get the xml data from a webservice) i don't know how. Is there any way you can define your schema, so it reads the correct data, but renames the column kinda like this: <xs:element name="date" type="xs:string" renamed-to="start-date" /> As far as i can see, there is no such attribute on the xs:element - or any other way to do it? All i want to do, is rename the column name and still (preferably) keep the relations to other tables/columns, without having to loop through the dataset creating a new one with different column names.

    - Deserialize problem with OracleException On August 19, 2003, a reader discovered that he couldn't deserialize an OracleException. He began a thread with Scot Rose of Microsoft where he described the nature of the problem. The reader wrote, "We have narrowed it down to the constructor OracleException (System.Runtime.Serialization.SerializationInfo si,System.Runtime.Serialization.StreamingContext sc), which looks for members "message" and "source", but the GetObjectData (...) method in the base (System.Exception) uses the strings "Member" and "Source". Since the element lookup in SerializationInfo is case sensistive, GetElement() and FindElement() fail and the OracleException deserialize throws an exception." Scot Rose asked for a small project and the reader provided one. There is no record of a response from MS. So here's another project, a console app, that demonstrates the problem. I am running framework 1.0 with a "hotfix" version of System.Data.OracleClient.dll, version 1.0.1088.0 that fixes some of the MANY bugs in this provider. Can someone from MS follow-up on this bug and provide a work-around? Imports System.IO Imports System.Data.OracleClient Imports System.Runtime.Serialization Imports System.Runtime.Serialization.Formatters.Binary Module Module1 Sub Main() Dim conn As New OracleConnection("Data Source=ussxt6;User Id=foresight_mcp;Password=xxx") Dim cmd As New OracleCommand("select * from blah_blah", conn) ' will throw "Table or View does not exist" Dim reader As OracleDataReader Try conn.Open() reader = cmd.ExecuteReader() Catch e As OracleException Dim formatter As New BinaryFormatter() Dim stream As Stream = File.Open ("c:\temp\foo.bin", IO.FileMode.Create, IO.FileAccess.ReadWrite) formatter.Serialize(stream, e) stream.Close() stream = File.Open("c:\temp\foo.bin", FileMode.Open, FileAccess.Read) Try Dim obj As Object = formatter.Deserialize (stream) Catch xx As Exception MsgBox(xx.ToString()) End Try Dim phoenix As OracleException = CType (formatter.Deserialize(stream), OracleException) MsgBox(phoenix.ToString()) Finally If Not reader Is Nothing Then reader.Close() If Not conn Is Nothing Then conn.Close() End Try End Sub End Module Tag: Unecessary spaces in table.

    - Detach SQL-Server Database from .NET Hi, I want to detach an SQL-Server database; what I'm doing is this: - Define an SQLCommand object with some SQLConnection - Change the database context to 'master' by setting "Database='master'" in the ConnectionString property of the SQLConnection - Set the CommandText of the SQLCommand object to something like "EXEC sp_detach_db @dbname=N'NameOfDatabaseToBeDetached'" - Open the connection - Call the ExecuteNonQuery() method of the SQLCommand object. My problem is: the database to be detached will always be reported as currently in use (error number 3703). Obviously, although I set the database context to 'master' explicitly, the established connection to the database to be detached seems to remain. How can I break the connection to this database?

    - Problems with OleDbDataAdapter with parantheses When I try to run a select through the adapter with a parantheses at the start of the select, the adapter will not run the select, and thus returning a empty dataset back. e.g (SELECT * FROM A UNION SELECT * FROM B) UNION (SELECT * FROM C UNION SELECT * FROM D) Even the simplest select will fail if it starts with (. Anyone have a solution for this problem? I use "Provider=MSDAORA.1;Password=test;User ID=test;Data Source=MyTestDB" as connection string The following code Dim objAdapter = New OleDb.OleDbDataAdapter(sPSQL, sConnection) Dim objDataSet = New Data.DataSet() Call objAdapter.Fill(objDataSet, coReturnValue) I can connect to the DB and run the selects without any problems.

    - Typed Dataset issue, Is this a bug IN VS 2003? I genereated typed dataset using several dataadapters in VS 2003. Now if I go to dataset view and click on property of any col. change it (for exsample make col. nullable) and save dataset, VB file associated with datase is gone. According to documentation vb file should be regenerated after each save of the schema. Am I doing something wrong? Is there anyway to manually force VS generate typed dataset based on excisted schema? I believe I was able to change schema in VS UI and VB file got updated automaticaly in VS 2002.

Why the hell is it that whenever I open a page in VS.net it always shoves
blank spaces before all of my text fields.

I am sick of this. I keep having to remove them every time I open the page.
