    - Inconsistent results with ADO.NET I have a class written in VB.NET which connects to a SQL Server 2000 database, executes a stored procedure and fills an ADO Dataset with the result set. Making the connection to the database and filling the dataset are both done inside of a Try...Catch statment to catch any exceptions. The program I have makes 2 main calls to this class, both of which return a result set from the database. When I run this program from my development machine (windows 2000 server) inside the development environment, the clsDatabase successfully fills the ADO datasets with data for both of the main database queries. When I deploy this program to other machines (both XP professional & windows 2000 server with the .NET framework v1.1 installed), 1 of the main queries returns data, but the other does not. I have code in the program to display a messagebox if the clsDatabase class encounters any exceptions, but none are thrown. I have used messageboxes to see if the code breaks while trying to connect to the database and while filling the dataset, but it does not encounter an error in either place. Both of my main queries are going to the same SQL Server with the same administrative login, yet only 1 of these 2 queries returns data on the deployment machines, while they both return data on my development machine. I would be appreciative of any advise anyone can give me. Thank you Tag: tabpage color? Tag: 90197

    - DataTable creating question? Hello, I have a large table in Sql Server that I want to populate from a VB.Net app. I have 2 data sources that are exactly the same structure but data from different geographic locations. I want to populate 2 separate dataTables in my VB.Net app (simultaneously on different threads) with the respective source data and then I want to merge the data from these 2 separate dataTables into a dataTable that I create from a Sql DataAdapter. I know how to use a Sql Adapater (sort of) Dim SqlDA As SqlDataAdapter = New SqlDataAdapter ... sqlDA.SelectCommand = New SqlCommand("Select * From tbl1",conn) ... sqlDA.Fill(dataSet1, "tbl1") - creates a dataTable with the correct schema. I tried doing the following with my 2 separate datatables Dim dt1 As DataTable = ds1.Tables("tbl1") Dim dt2 As DataTable = ds1.Tables("tbl1") But dt1 and dt2 turned out to be the same table. If I place from 1 to 1000 records in dt1 and 1001 to 2000 recs in dt2 (simultaneously using multithreading), tbl1 contains 4000 recs, not 2000. I would like to create dt1 with the same schema as tbl1 and dt2 also. Then I want to transfer the data from dt1 and dt2 into tbl1. In my situation, simultaneously pick up data and place it into tbl1 where I end up with 2000 records, not 4000. What is the best way to do this? How do I transfer the data from dt1 and dt2 into tbl1 (not even worried about updating the Sql Server table for now - just end up with 2000 records in tbl1 from dt1 and dt2). TIA, Rich Tag: tabpage color? Tag: 90190

    - Syntax for convert in ado.net I have a dataadapter that I pass a sqlcommand to, which has paramters. I have the following sqlcommand on my page: SELECT * FROM tbl_Changes WHERE (CAST(@column1 AS nvarchar(20)) LIKE @Criteria1) and have the following code to call this sqlcommand in my webpage: cmdSelectNone.Parameters("@Column1").Value = "Change_Status" cmdSelectNone.Parameters("@Criteria1").Value = "%" & txtSearchCriteria1.Text & "%" SqlDataAdapter2.SelectCommand = cmdSelectNone SqlDataAdapter2.Fill(DsChanges2) dgSearch.DataSource = DsChanges2 dgSearch.DataBind() Every time I call the above code it returns no records, yet if I comment out the '@column1' parameter in the code and hard code the column name in the sqlcommand it works just fine. Could anyone please tell me what's wrong with my cmdSelectnone.Parameters("@Column1").value="Change_Status" line please?? Thanks in advance, Jason Tag: tabpage color? Tag: 90184

    - Large DataSet Question Hi, I am retrieving a dataset with over 100 records and can vary based on user in which it can get even larger. I am displaying the dataset in a datagrid. I was looking for reccomendations on how to breakup the dataset because I do not want to show 100 records in a datagrid. I was thinking about limiting the dataset to 50 records based on the a stored procedure, is that a better idea? The stored procedure is based on a like clause which the user enters.

    - duplicating a DataRow Hi All, I've got a strongly typed DataSet where I want to: traverse the rows in a table and do a check. If the check is successful, I want to duplicate the row, tweak a column, then add it to the same table in the DataSet. What's the most efficient way to do this? I tried to 'new' a new DataSet-derived DataRow (and hoping to copy a row into it), but the constructor wanted a DataRowBuilder, which i don't have. DataRowBuilder appears to be an internal object, not useable by us developers. Also, the table has 34 columns and it's a pain in the rear to write all the code to deal with the DataRow indexes. Is there a better (less typing) way to do the copy, or do I have to deal with the base DataSet class exclusively? Thanks in advance! Corey. Tag: tabpage color? Tag: 90167

    - DataRowView.Row == Null??? Hi all, I have noticed some weird behavior of the DataView. When I call DataView[i].Delete() on a DataView it appears that the row is deleted. But sometimes the DataRowView lives on, but the underlying DataRow is null. Also, I handled the DataRowChanged event and inside of there I do a GetChildRows() on that same table, but along with all the valid rows, a null value is returned. It's as if the underlying DataTable still thinks the row is there even though it is not. I am changing the DataView.RowFilter inside of the RowChanged/RowDeleted events. I think this is what is causing the problems. I change the filter on the child view when the parent view updates its primary key and it appears that this is what is causing the funky behavior. That's my best guess. I have got around the problem by updating all my rows first and then going through and doing the deletes separately. Has anyone else experienced anything like this??

    - lock records for update: how? options? Hi, I know ADO.Net recommand using disconnected update (optimistic concurrency) for good reasons, but it's just not an option for us. 99% of our client would rather seeing "record locked" kind of message up front when they load records, than being told "updating failed" after they spend all the time entering the data. So here I am spending a lot of time trying to find a good way to do the "read with lock" type of opration. I know you can do some thing like that, at the query level, if you are running some late version of SQL server, but what if I can't use those DB specific features? Is there a recommanded way of doing this at ADO.Net level"? What about ADO.Net's transaction? If someone can point me to a right direction that would be highly appreciated!

Why????? I find a article http://www.dotnet247.com/247reference/msgs/49/248580.aspx And find this one !!!!!!!!!!!!!! " Michael Bachar Hi, I'm using ADO.Net in C# with Oracle9i Release 9.2.0.4.0 when loosing the connection with the Oracle database server the connections doesn't recover and always returning the following exception even when the connection has been restore: "ORA-03114: not connected to ORACLE". I'm closing the connection properly in that it will return to the connection pool. Here is an example code: using(OracleConnection conn = new OracleConnection(connectionString)) { conn.Open(); using(OracleCommand cmd = new OracleCommand(sql, conn)) { object obj = cmd.ExecuteScalar(); } } This should close the connection properly. In the MSDN it is mention that if the connection pooler detect that the connection with the server has been severed it will remove the connection from the connection pool. It appears that this is not happening an I always get bad connections from the pool, even after the connection with the database server has been restore. How can I solve this? What is the proper way to recover from connection lost with database server? Thanks, Michael. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Angel Saenz-Badillos[MS] (VIP)!!!!!!!!!!! Michael, I am sorry this one is my fault and it is a very bad bug.!!!!!!!!!!!!!!!!!!!! The problem here is that our pooler fails to understand that a 03114 exception means we should not put the connection back in the pool. We have a QFE that fixes this problem by discarding the connection in the following Oracle exceptions. Please let me know if you know of any other exceptions that also result in a connection no longer being valid. oracle exceptions checked case 18: // max sessions exceeded, case 19: // max session licenses exceeded case 24: // server is in single process mode case 28: // session has been killed case 436: // oracle isn't licensed case 1012 //not logged on error case 1033: // startup/shutdown in progress case 1034: // oracle not available case 1075: // currently logged on case 3113: // end-of-file on communication channel case 3114: // not connected to ORACLE case 12154: // can't resolve service name case 12xxx //any error starting with 12 thousand To get the fix please contact PSS directly and request QFE 830173 " ????

    - Speed of inserting data in table SqlServerCE I have written some proof of concept code that adds records to a table, utilizing SqlServerCe, using a parameters in a insert statement. I am forced to read data from a BinaryStream (in the form of a file), assign values to the parameters and execute the sql insert statement from within a while loop The table contains 11 fields, and it currently takes over two minutes to read 4500 records... This is maddness, as I am porting from an old application, and I can accomplish the above in about 2 seconds using my old code (written in OPL) using a device thats 4x slower than the one I'm currently developing on. Anybody have an idea how to speed this up? or mybe a sneaky workaround... :) Regards BM Tag: tabpage color? Tag: 90156

    - Getting information messages back in real-time Hello, It's possible to create messages in SQL Server 2000 that get sent to the client immediately, by using RAISERROR ... WITH NOWAIT. For example, the following code works great in Query Analyzer: RAISERROR(N'Message 1', 0, 1) WITH NOWAIT WAITFOR DELAY '00:00:02' RAISERROR(N'Message 2', 2, 1) WITH NOWAIT WAITFOR DELAY '00:00:02 RAISERROR(N'Message 3', 4, 1) WITH NOWAIT WAITFOR DELAY '00:00:02' However, I find that when I try to execute a script or procedure from ADO.NET, and try to receive these messages using the InfoMessage delegate, I don't get them until the very end, all in one chunk. I'm writing a long-running procedure, and I'd like the client to be able to receive status messages to print to the console. Is there any way to get messages to get sent to the client in real-time?

    - .NET and SQL Server on Separate Machines Hi all, We're working on an ASP.Net Web Application that makes several calls to a SQL Server database. Everything was running correctly when the database and the web server were on the same computer, but we have sinced moved them to separate computers; IIS V6 on Win2000 and SQL Server 8(SP3) on Win Serv 2003 Ent. The connection string in our web.config file originally looked like this: <add key="ConnectionString" value="server=localhost;Trusted_Connection=true;database=Store;" /> After moving the database (and changing the server in the connection string), we started to receive this error: "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection." We ended up changing the connection string to look like this: <add key="ConnectionString" value="Integrated Security=SSPI;Initial Catalog=Store;Data Source=192.168.0.12;" /> This string only works if we add the following to the .config file: <authentication mode="Windows" /> <identity impersonate="true" /> Unfortunately, the web application was designed to use forms authentication, so we're still looking for a valid connection string. We've tried setting Trusted_Connection=false and providing a username and password, but we get the same error as before - only with the provided username listed instead of (null). We've tried setting the database to mixed mode, and Win Auth only and got the same results.

Assume I have now updated the textbox with 'Bloggs' and I've hit the UPDATE button (code as follows): Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim conCOMP As SqlConnection Dim cmdUPDATECOMP As SqlCommand conCOMP = New SqlConnection("xxxxxx") strCOMP = "UPDATE ClientDetails SET colSurName= '" & txtSName.Text & "' WHERE ClientRef = 100" cmdUPDATECOMP = New SqlCommand(strCOMP, conCOMP) Label4.Text = strCOMP conCOMP.Open() cmdUPDATECOMP.ExecuteNonQuery() conCOMP.Close() End Sub I've added a label here to view the value of the UPDATE command when it is passed BUT it gives the value already stored in the DB / or rather the value it already got in the Page_Load routine: the text in Label4 is: " UPDATE ClientDetails SET colSurName = 'Smith' WHERE ClientRef = 100 " I think it is obviously the text box variable: having got a value for when the Page_Load event occurs. But how can my clients change the text boxes to update their details and hit UPDATE?????? PLEASE PLEASE HELP. This seriously has been BUGGing me for a month. My Client is not happy :( Tag: tabpage color? Tag: 90089

    - Autoincrementing Primary Keys with PostGres I am using an ODBC connection to a PostGres database, that has various tables that use SERIAL types to implement automatically incrementing primary keys. My problem is that I have a dataset containing tables that I have turned AutoIncrement on, and set the seed and step to -1. My update statement works a treat, and any new rows are added sequentially to the end of the table. However, I need a way of immediately returning a new rows primary key, in order to keep the dataset up to date. I know that in SQL Server you can use the @@IDENTITY feature, to immediately return the last used value. Is there something similar in PostGres? I have tried adding a 'SELECT CURRVAR('public.equipmenttype_equipmenttypeid_seq') just after my insert statement (which is the SQL that you use to find out the current sequence id in PostGres), but I am not sure of the ODBC syntax needed to get this information into a parameter (I assume I would need to use a ParameterDirection.ReturnValue). This problem has been vexing me for a few days now. Any ideas or a better way of handling autoincrementing keys would be gladly received. Tag: tabpage color? Tag: 90076

    - DataTable column question Hi! It's easy to add Columns into DataSet DataTable for example like this way ... ds.Tables("MyTable").Columns.Add("MyColumn", GetType(Integer)) ... but how can I remove this column of the DataSet which was created earlier by code? Do I have to create whole new DataSet table again? I mean something like ds.Tables("MyTable").Columns.Remove("MyColumn") - ofcource it's not possible to do like this way :) I tried ... ds.Tables("MyTable").Columns("MyColumn").Dispose() ... but it doesn't seem to do what I want. -- Thanks in advance!

    - Persistent UPDATE Problem Hi there I have had an application where I have not been able to successully add an 'update details page' for my clients logged in to the website. I have posted a query on this before and the result was that the WHERE clause was probably wrong; without success....but I have added a test labels to test so now know a little more so hopefully you can help. Have ASP.NET / SQL Server 2000. The web app has a members area which is https. i'm using authenication ticket which stores the member ID ref as a state variable called 'MemberRef' So problem page.... When this UPDATE PERSONAL DETAILS page loads, it fills the textboxes on the page with a datareader according to who is logged in. One textbox example is as follows: txtFirstName.Text = rdr("colFName") Then of course I need a process so my members can update their personal details stored in the DB, so those text boxes allow updates and I've added a button which should update the DB Private Sub ButUpdatePractice_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) 'Handles ButUpdatePractice.Click Dim strCOMP As String Dim conCOMP As SqlConnection Dim cmdUPDATECOMP As SqlCommand conCOMP = xxx cmdUPDATECOMP = New SqlCommand(strCOMP, conCOMP) strCOMP = "UPDATE ClientDetails SET colFName = @Fname WHERE MemberRef = @MemberRef" cmdUPDATE.Parameters.Add("@Fname", txtFirstName.Text) cmdUPDATE.Parameters.Add("@@MemberRef", MemberRef) conCOMP.Open() cmdUPDATECOMP.ExecuteNonQuery() conCOMP.close -now plrease ignore any misspellings above - done it for speed for this forum. Now this doesn't update the DB when pressing the update button. It re-freshes the page. I've added a label to the page which shows the strCOMP update string on the page to test ( label1.text = strCOMP ) and it contains the existing value from the DB. Please help. Tag: tabpage color?

    - Dataset constraint violoation with null foreign key value Hi, I'm loading a dataset from a cached viewstate version of the dataset created on a previous http request. When I read the call ReadXml on the typed dataset, I get: "Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints" I suspect this is due to a field in one of the tables which can be null, but if it is not null it is a foreign key to another dataset table. At present the field in this table is null (in the database). What attributes of the dataset table field, or the dataset constraint should I set to indicate null values don't violate the constraint?

    - Datagrid hide identical columns from a JOIN I do not normally use JOINS in my queries these days, but I have some instances where I am simply showing historical data in a grid, and it is thus much more convenient to JOIN everything I need in one stored procedure. Thus I might end up with data from 3, 4 or more tables -- some with identical names (the JOIN criteria). I know how to hide columns in a straightforward query, but how about in a JOIN query where you may have 2 or even 3 or more identical field names (IDs usually)? How do you hide, for example, the SalesID from the 2nd table or the from the 3rd table? For example, the following statement works for the first SalesID, but what about the other JOINED SalesID fields? (I've tried "SalesID1" and "Expr1", but no joy except SalesID1 seems to work on a simple query with 2 joined tables). ds.Tables("dtSalesPayments").Columns("SalesID").ColumnMapping = MappingType.Hidden Tag: tabpage color?

    - .NET SQL Client: Connection pooling issue Hi All Follow up to my last week' postings on connection pooling issue we experience. Thanks all for your replies but since I still don't have a solution ? I've decided to start a new thread. Here is a link to the original thread: http://tinyurl.com/yu68q We use SQL Client (SqlCommand, SqlConnection and SqlDataReader) in our 3-tiered ASP.NET app written in C#. The problem we are running into is that under heavy load the number of pooled connections increases approximately by the current pool size every time the garbage collector kicks in. This happens even when only about 60 connections exists in the pool with the max size of 100. The number of pooled connections does not grow until the GC engages and ? the most puzzling ? the new connection pool is being created at that very moment. I rely on .NET CLR Data performance counters which I suspect might not be reliable. But if they aren't ? what is? The documented MS Knowledge base issue with the counters http://support.microsoft.com/default.aspx?scid=kb;en-us;314429 doesn't seem to apply here) I also follow all the good coding practices such as closing the connection and DataReader in the finally block. I do not have any destructors or Finalize implementations in the app as well. I have performance monitor screenshots for all interested. Any ideas? Thank you! Tag: tabpage color? Tag: 90054

    - HLP: Adding Column Info to ListView What I'm trying to do is to Add the information of Two Tables into a single ListView. The ListView has 10 columns. The following Code populates the LV columns 1 to 5 (or rather 0 to 4) from a DataSet... Private Sub MstrEmPay() Dim dtDataTbl As DataTable = DsMstrEmPay.MASTER_PRM_EMPLOYEE_PAY ' Get Info from Data Base For cntr = 0 To DsMstrEmPay.MASTER_PRM_EMPLOYEE_PAY.Rows.Count - 1 Dim dr As DataRow = dtDataTbl.Rows(cntr) Dim LItem As New ListViewItem Dim rowTtl As Double = 0 LItem = New ListViewItem LItem.Text = dr("amount") LItem.SubItems.Add(dr("employee")) LItem.SubItems.Add(dr("pay_id")) LItem.SubItems.Add(dr("pay_type")) lvProjDisplay.Items.Add(LItem) Next ' cntr End Sub What I want to do is to get the info of another DataSet and dump it's info into the next 5 remaining Columns (starting at the first row of the ListView). I've done some reading and I 'think' I need something like: LItem.SubItems.Insert(5, myTextHere)... but haven't found how to make this work. Anyone can help? Regards, Bruce Tag: tabpage color?

    - Making an app run on a local area network. I realize I have asked this question before and the answer is slowly becoming clearer but I do not yet quite have it in place. I have a VB.net application that I have written from a client machine of a local area network. The LAN has a dedicated file server. The solution is located in a shared directory of the LAN's file server The drive letter is F. The application is bound to a SQL Server 2000 database that also resides in a shared directory on the F drive of the file server. My application works on the machine I am using but then I have a full blow copy of VS 2003 installed on the machine. I would like to be able to run the application from other machines on the local area network. These other machines all have Windows XP Pro installed and the .net framework. What do I need to do in order for this to happen? If I understand correctly I do not have to even worry about creating a .MSI file; I can simply point the other machines to the .exe file that is created in the Bin directory of the application that, again, is located in a shared directory of the server. Is this right? What else do I need to do in order to make (allow) this application to run from other machines on the Local Area Network? Tag: tabpage color? Tag: 90042

    - detaching an XmlDataDoc from a DataSet Hi All, I've got an XmlDataDocument that is attached to a DataSet with one DataTable in it. Then I take the XML as text and throw it into a Text Box on a form. Later on, I wanted to add another DataTable to the DataSet and it complained: Cannot add or remove tables from the DataSet once the DataSet is mapped to a loaded XML document. How do/can I detach the XMLDataDoc from the DataSet? Thanks! Corey. Tag: tabpage color? Tag: 90040

You have to write custom code for it.

Here is an example -
