    - Cint(null) Hi I have code that stores integer data from the control to the database. (I am using Option Strict). The problem is when I try to do the code below, I get that the string is not properly formatted because there is no value. Each page has a lot of variables. Is there a way to solve that problem without having to have an IF block for each variable? myNewRow("score1") = CInt(SCORE1.Text) Thanks W Tag: Webservices + oracle connection problem Tag: 118372

    - What wrong with this simple code snippit? Hi all, Whats wrong with the below code? On every loop it seems to be jumping 3 sometimes 4 records. As you can see the SQL query is asking for all records with no filters. I want to loop each record as I asked. Is there something with wrong with my code? Thanks in adavnce, Steve. string str_SQLLayoutsPound = "SELECT * FROM Layouts";. OleDbCommand obj_SQLLayoutsPound = new OleDbCommand( str_SQLLayoutsPound, obj_SourceConn ); OleDbDataReader obj_ReaderLayoutsPound = obj_SQLLayoutsPound.ExecuteReader();. while( obj_ReaderLayoutsPound.Read()) { string str_CurrentRecord = obj_ReaderLayoutsPound["Name"].ToString(); } -- Message posted via DotNetMonster.com http://www.dotnetmonster.com/Uwe/Forums.aspx/dotnet-ado-net/200509/1 Tag: Webservices + oracle connection problem Tag: 118368

    - Question about isolation level using OracleClient library Hi, all, When I use OracleClient library to connect with Oracle Database and set transaction's isolation level to serializable level, it should can prevent phantom read from happening. But unluckily the phantom read happens. And if I use ODBC library to do all the same things as above, the phantom read will not happen. It is very confusing, and I looked for related infomation in internet, and got none. Would anybody help me and tell me why? BTW, the version of .Net Framework is 1.1, and the both versions of the oracle server and client are 9.2.1.0. Thank you in advance. Tag: Webservices + oracle connection problem Tag: 118367

    - serviced components and shared methods how does the enterprise services infrastructure treat shared (static ) declared methods? does the class the shared method is declared inside it must be serviced component in order for the method to get transaction services? because instance of the class does not have to exist and even if exist, not related to the method call.

    - Does ExecuteReader allow you to return a record name? Hi all, I''ve created an OleDbDataReader that will contain the number of records that the used SQL query will return. I'm then using a while loop to loop while the OleDBDataReader object has records. I would like to know does the OleDbDataReader contain the actual information on each record i.e. the fields in the database and their values? Or does the ExecuteReader command only contain the number of records present from the used SQL query and no more? Or am I going the completely wrong way about it?? I need to use the 'Name' field's value of the current OleDbDataReader record in a following (not present in code snippit) code block. I using an Access 2000 database. Thanks in advance, Steve. OleDbDataReader obj_ReaderLayoutsPound = obj_SQLLayoutsPound.ExecuteReader(); while( obj_ReaderLayoutsPound.Read()) { // Is there a property of the OleDbDataReader that will contain the information of each record? string str_CurrentRecord = obj_ReaderLayoutsPound.ToString(); } -- Message posted via DotNetMonster.com http://www.dotnetmonster.com/Uwe/Forums.aspx/dotnet-ado-net/200509/1 Tag: Webservices + oracle connection problem Tag: 118363

    - Howto obtain the credentials from a SqlConnection object Hi all, In the ConnectionString property you can set the UserName and Password to be used for the SqlConnection as well as the DataSource and Initial Catalog (and some more possible values). There are properties on the SqlConnection object which return the DataSource and the Database provided in the ConnectionString but there are no such properties for the UserName and Password. I'm creating a class which is using DTS object to generate an Excel file and I would only like to provide a SqlConnection object, a CommandText and a CommandType to the class. The DTS Connection2 object has separate properties for Datasource, Catalog, UserID and password. Now I have to provide the UserName and Password as separate parameters to the class because I can't derive them from the SqlConnection object. Parsing the ConnectionString seems a bit tricky because you can provide the username with different keywords like: "uid" or "User Id', the same goes for password. And I don't know if there are more possible keywords. Does anybody know a way to to achieve what I want? TIA, Friso Wiskerke Tag: Webservices + oracle connection problem Tag: 118362

    - How to retrive schema bound with a SELECT statement columns? Hi , We are developing an application in C# to compare data retrieved by two SELECT queries. User Input for data comparision is two valid SELECT statements which returns data. Before starting the data comparison, i would like to validate the data type of all the columns which are listed in the select statment are same. For example i've the following two queries Query 1: SELECT t1.Col2, t2.Col3, t4.Col5 FROM ....... Query 2: SELECT A.Id, B.Name, C.Age FROM ..... Now i want to verify the selected columns from both the queries are having same data types and column length before extracting data for comparision. i.e i want to make sure that data type and column lenght of t1.Col2 is equal to A.Id t2.Col3 is equal to B.Name t4.Col5 is equal to C.Age. I tried working with DataAdapter.FillSchema but i'm not able to get proper information requried for validation. Most of the SQL data types are being mapped to Sytem.String and for data types i'm not able to get exact length. So i'm not able to differentiate the underlaying datatypes. please help me in validating the data types and length of colunms which are selected in the query? Regards, Gopi Can you please tell me how to retrieve schema associated with a query? Here is the sample query for which i want to know DATATYPE, LENGTH of every column which i'm selecting in the query. SELECT Tbl2.Name, Tbl3.Age, Tbl1.ID, Ttb2.DOB FROM Table1 Tbl1, Table2 Tbl2 WHERE Tbl1.Key = Tbl2.Table1Key Thanks in advance for spending your valuable time to look in to this problem. I would be very much thankfull to you if you help me to write SQL script( or C# code) to get the schema bound with the query.

    - project with serviced components and non services components i have a project and i want few of my components to be services. but other classes i don't declare as serviced. should this cause any problem? and what if a seviced object calls a non services object (that might call another serviced component), can this cause problems?

    - serviced component question i have a vb.net class that Implements IDisposable. now i want to make that class services, so i make it inherits servicedComponent. now i get this error message: sub 'Dispose' shadows an overridable method in a base class. To override the base method, this method must be declared 'Overrides'. now that's OK, i can declare the sub as overrides, but should i take anything else into consideration? like calling the base.dispose inside my function. must I?

    - Help me in Specifying Connection string to SQL server 2000 running on remote machine Hi All I am dealing a project in ASP.NET in which I have to establish a connection to SQL Server 2000 database,where the database was located on a remote system. For this I have used SQLConnection object and specified the connetion string.But when it comes to establish a connection its giving me the Error that I. Connection string : workstation id=localhost;packet size=4096;user id=sa;data source=192.168.0.106;persist security info=False;initial catalog=db Error : System.Data.SqlClient.SqlException: Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection. then I have inserted one new attribute 'Network = dbmssocn' and modified the connection string as below II. Connection string : workstation id=localhost;packet size=4096;user id=sa;data source=192.168.0.106;Network=DBMSSOCN;persist security info=False; initial catalog=db then I got the below Error when try to establish a connection. Error : System.Data.SqlClient.SqlException: SQL Server does not exist or access denied Note: 1.

    - ADO.NET AddNew EndCurrentEdit & "Column 'Appt_ID' does not allow nulls" SOLVED I see this question asked in different ways both in this newsgroup and on bulliten boards, I just stumbled on the fix. What I had was basically correct, but missing one line. In the Update button, after this: Me.BindingContext(DsAppointments1, "Appointments").EndCurrentEdit() THIS is required to write the data back to the DB: OleDbDataAdapter1.Update(DsAppointments1) The .net help implied that EndCurrentEdit() wrote to the DB, and didnt mention updating the adapter where it should have been mentioned. I tweaked the code a bit in other areas, the final code I'm using for the ADD and UPDATE buttons follows: btnADD_click... REM move to the last record Call btnLast_Click(Nothing, Nothing) REM Access the DataTable object Dim myTable As DataTable = DsAppointments1.Appointments() REM confirm properties for Primary Key are properly set myTable.Columns("Appointment_ID").ReadOnly = False myTable.Columns("Appointment_ID").AutoIncrement = True REM Clear the text boxes of their current record data Me.BindingContext(DsAppointments1, "Appointments").AddNew() btnUPDATE_click... REM Tell VB youre done editing Me.BindingContext(DsAppointments1,"Appointments").EndCurrentEdit() REM Tell VB to write the data you added to the DB OleDbDataAdapter1.Update(DsAppointments1) One FYI: column numbers, such as myTable.Columns(0).AutoIncrement = True At least seem less reliable in .net than they were in VB 6 Tag: Webservices + oracle connection problem Tag: 118351

    - Related Tables in Different Databases; how to query Database1 contains a table of people with addresses (sql Server) Table: People MasterID MasterName MasterAddress1 etc. DataBase2 Contains a table of people and the property they own. (msAccess -> imported from the sqlServer but detached) Table Property PropertyID MasterID PropertyDescription, etc. I can easily put together oledbdataadaptors to fill a common dataset (dataset1) with: People Table and Property Table My task is to generate a table/view something like SELECT Property.PropertyDescription, People.MasterName, People.MasterAddress FROM Property INNER JOIN People ON Property.MasterID = People.MasterID; I'm at a loss as to what Ado.net widget, and/or process to use to do this. It would be easy if they came from the same database (they sorta do but we can't go there) ;>. The only approach I can dream up is to create a temp table in one of the databases of the data from the other then do a query, but for several reasons, I would like to find a more 'elegant' way to do this.

    - Business objects and class' w/ member DataSets I'm designing my data access needs and have a couple of questions. First of all, I can't get a straight answer what a "business object" is. I typically create classes to represent my database tables, are those "business objects"? Is it more typical to pass the business objecs to the DAL methods or have the business objects generate correct SQL and pass commands to the DAL? I'm thinking of trying out a new type of business object where I encapsulate a DataSet or DataTable in my object. Something like: <code> class BCustomer { private DataSet m_rawData; public string CustomerName { get{ return m_rawData.Tables[0].Rows[0][0]; } // assuming this is the index to the customer name? set{ m_rawData.Tables[0].Rows[0][0] = value; } // ditto } } </code> This gives me strong typing and the flexibility of the DataSet/Table Is this common?

    - DataGridView: Index -1 does not have a value Hi, I'm using the DataGridView in VB.NET 2.0. The DataSource is a Generic List of a custom class0: lstMyPersonnes = New List(Of clsPersonne). When I add a new clsPersonne to lstMyPersonnes, and rebind the lstMyPersonnes to my DataGridView.dataSource, it shows the new record in the DataGridView as it should be.

    - Help with adding stuff to a database please Im just converting an app to .net (using VB) and I decided to use ado.net also, rather than sticking with plain ado. I have got my queries running fine with datareaders, but I'm having a little trouble inserting records.

I get an exception of "Object reference not set to an instance of an object" at the line marked with * and checking my debug, workTable is still "nothing".

    - ADO.NET AddNew EndCurrentEdit & "Column 'Appt_ID' does not allow nulls" Having spent a lot of time Googling over the last 2 days, this seems like a common problem, but I havent run into any answers: My VB.Net front end loads data from an Access database successfully, and navigation works fine. However, I cannot add a record. Code is as follows: In my Add New Record button: REM move to last record Call btnLast_Click(Nothing, Nothing) REM clear text boxes, prepare for new record Me.BindingContext(DsAppointments1, "Appointments").AddNew() In my Update button: REM commit to adding new record Me.BindingContext(DsAppointments1, "Appointments").EndCurrentEdit() When that last line of code fires, I get the following error (I know this must be starting to look familiar to experienced coders): -------------- "An unhandled exception of type 'System.Data.NoNullAllowedException' occurred in system.data.dll Additional information: Column 'Appt_ID' does not allow nulls." -------------- Appt_ID is the primary key and is set to autonumber in the Access database. I have tried too many things to even mention here, but I cannot get this to work. I'm sure someone out there has gotten it to work, and I'd love to know how. :-) Also, a curiosity.

    - Event for Field Change I am a Delphi programmer who is excited about converting to .Net (however still novice in .Net), and I need your help to understand some data manupulation concepts. I am using I have a typed DataGrid bound to an access database, which has a table with 2 datetime fields: Date1 and Date2. I added an unbound column to the grid called ELAPSED, which will diplay the difference in days between the 2 dates. So the grid looks like this: DATE1 DATE2 DIFF ------------------------------------------ __/__/____ __/__/____ 999 days __/__/____ __/__/____ 999 days __/__/____ __/__/____ 999 days __/__/____ __/__/____ 999 days __/__/____ __/__/____ 999 days I wrote a method to calculate the difference in days (using TimaSpan), and I want to run this method for each row, as it's been "filled" from the database. Additionally, I want this method to be run as I change DATE1 or DATE2 in the grid, so that the it reflects the correct difference in days. Please help me to achieve this, explaining in what event(s) I should place the call to my method. PS: In Delphi I would put it in the TField's OnChange event...

    - Multiple DataViews on the same DataTable appear to interact I have a DataTable that is being maintained in a Model class. I also have a View class which creates a DataView from the DataTable that the Model passes it. The view class then has methods to filter the contents of the DataView so that the user can narrow down the list to the items they are interested in. This all works fine as long as I only have a single instance of the View class, however whenever I create a second instance of the view class and have it make its DataView use the same DataTable I find that any filter applied to the DataView in one window is also applied to the DataView in the other form. Can anyone explain this to me? It seems that as long as I am using 2 independant DataViews (dim dv as new DataView(model.GetTable()) they shouldn't interact.

    - "Timeout expired" in ADO.NET Hi, I've sent a similar post earlier - but after no more luck and a lot more frustration, I am reposting the issue with some additional information. It's regarding several web applications on the same server, connecting to a SQL Server on another server. I keep getting the following exception when accessing the database: ----- System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. ---- I am currently using the following code to connect, but I've had the same problem with all the different code snippets I've tried, so I doubt the problem lies herein: ----- using (SqlConnection connection = new SqlConnection(connectionString)) { connection.Open(); .... data code .... connection.Close(); } ----- The problem happens 1-5 times, after I refresh the page enough times, it usually goes through. I've seen a number of potential solutions to the problem - but none of them fits the problem. I usually get the exception after not using the system for a while, but I haven't experienced when the system is "in use", i.e. when the previous request was no more than a couple of minutes ago, and no recompile of the application has been done. I _don't_ get enough connections to exceed the maximum - far from it (when I don't get the exception, the connection pooling seems to work fine). The exception is thrown instantly, not after the default 30 second timeout. And after I had accidentally misconfigured the authentication in the web application, the user didn't have access - I got "Login failed for user (null)" - what's odd was that I _still_ got the "Timeout expired" exception 4-5 times before I finally got the expected "Login failed" exception. The "Timeout expired" exception gets thrown even before I successfully connect to the database! Suggestions are very welcome, I've been struggling with this problem off and on for several weeks now. It's only a big nuisance during development, but naturally, it's a real showstopper for going into production with the application(s).

    - ADO.Net 2 Providers Hey all, I've been extremely pleased in both the Beta 2 and RC releases of VS.Net 2005 and the new .Net Framework 2. There is just a little something that has been bothering me, and a problem I just cannot seem to resolve? As far as I'm concerned, will there not be any updates to the ADO.Net data providers especially OLEDB and Jet 4. Is this correct? I started out a little project using the .Net Framework 1.1, and somewhere within this project I reference a connection to an Excel document making use of OLEDB as there is no way I can use SQLClient? This has been working fine ever after I upgraded to .Net Framework 2 Beta 2 release 2 months ago. Over this weekend, I updated my release to the RC to try and test the release but for some ob reason I get a "System.EnterpriseServices.Wrapper.dll cannot be found" exception thrown as soon as the code enters the "ReadXLS" method within my code? Now I did a file search and found the file in the .Net Framework directory and I made sure that my project references the "System.EnterpriseServices" namespace. Is there something I am missing here, or will I need to reinstall the Framework again, as I've tried this before? Any help would be greatly appreciated! -- "Code .... really, what''s that?"

    - Inserts to DataSet aren't added to db - updates work fine Here is a newbie question, but this one is driving me crazy. In a VB.NET Windows form application, I am inserting and updating records in a DataSet, which show up in a bound DataGrid just fine. I am also issuing a DataAdapter.Update command, and the updates are saved to the database but the inserts are not. As far as I can tell, I am following the two examples that I have to the tee, but it just doesn't work. I'm sure that I'm overlooking some simple detail. FYI I am using an OleDBCommandBuilder to build the insert and update commands. I moved all of the relevant code into a single form to create a simplified example, and it follows. Thanks in advance!!!! ---------------------------------------------------------- ' this project has a single window with a bound DataGrid that 'displays a single user's "contact information", which is one row ' 'clicking on btnUpdate updates that one record 'clicking on btnInsert inserts a new row 'both updates and inserts are immediately visible in the DataGrid 'but only the updates are saved in the database Public Class Form1 Inherits System.Windows.Forms.Form Private oleConnection As OleDbConnection Private Shared connString As String Private sql As String Private daCustContact As New OleDbDataAdapter Private dsCust As DataSet Private cmdCustBuilder As OleDbCommandBuilder Private cmdCustContact As New OleDbCommand Private cmdCustContactBuilder As OleDbCommandBuilder Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load connString = " .. my conncetion string .." oleConnection = New OleDbConnection(connString) oleConnection.Open() dsCust = New DataSet("CustomerContact") cmdCustContact.Connection = oleConnection cmdCustContact.CommandText = "SELECT CustomerNumber, ContactAddress, MethodType, SequenceNumber, InactiveDate " _ & "FROM CustomerContact " _ & " WHERE CustomerNumber = 526" daCustContact.SelectCommand = cmdCustContact daCustContact.TableMappings.Add("Table", "CustomerContact") cmdCustContactBuilder = New OleDbCommandBuilder(daCustContact) cmdCustContactBuilder.QuotePrefix = "[" cmdCustContactBuilder.QuoteSuffix = "]" daCustContact.UpdateCommand = cmdCustContactBuilder.GetUpdateCommand daCustContact.InsertCommand = cmdCustContactBuilder.GetInsertCommand daCustContact.DeleteCommand = cmdCustContactBuilder.GetDeleteCommand daCustContact.Fill(dsCust, "CustomerContact") DataGrid1.SetDataBinding(dsCust, "CustomerContact") End Sub Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click With dsCust.Tables("CustomerContact").Rows(0) .Item("MethodType") = "Fax" .Item("SequenceNumber") = Convert.ToByte(10) .Item("ContactAddress") = .Item("ContactAddress") & "xxx" End With UpdateCustomerContact() End Sub Public Sub UpdateCustomerContact() BindingContext(dsCust.Tables("CustomerContact")).EndCurrentEdit() daCustContact.Update(dsCust, "CustomerContact") End Sub Private Sub btnInsert_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnInsert.Click Dim dtCc As DataTable = dsCust.Tables("CustomerContact") Dim dr As DataRow = dtCc.NewRow() dr("CustomerNumber") = 526 dr("MethodType") = "Email" dr("SequenceNumber") = 2 dr("ContactAddress") = "hacking code" dr("InactiveDate") = System.DBNull.Value Try dsCust.Tables("CustomerContact").Rows.Add(dr) dr.AcceptChanges() dsCust.AcceptChanges() UpdateCustomerContact() Catch ex As Exception MessageBox.Show("Exception occurred: " & ex.Message, MessageBoxButtons.OK, MessageBoxIcon.Error) End Try End Sub Public Sub UpdateCustomerContact() BindingContext(dsCust.Tables("CustomerContact")).EndCurrentEdit() daCustContact.Update(dsCust, "CustomerContact") End Sub End Class Tag: Webservices + oracle connection problem Tag: 118245

    - Two questions for gurus about using strongly typed DataSet in Web Services. 1. Is there a 2nd way to declare a strongly typed DataSet (e.g. CustomerDataSet) in WSDL instead of using the WSDL <import namespace="CustomerDSnamespace" location="url to CustomerDS.xsd"/>? Apparently, if I include CustomerDataSet schema definition in WSDL types, it will not be recognized as a DataSet by .NET WSDL compiler when a Web Reference is created. I have to use the WSDL import statement. What do I need to do to make it recognize the CustomerDataSet definition in the WSDL types. The CustomerDataSet has the correct definition (ie isDataSet=true) and does work with the WSDL import. 2. How to send a strongly typed DataSet over SOAP without the XSD? I found that when I am sending a strongly typed DataSet (e.g. CustomerDataSet) instance over SOAP, I still need to send its XSD with the CustomerDataSet every time. Otherwise, .NET will not parse attribute data type right even though, the XSD is available as part of the strongly typed DataSet (ie CustomerDataSet). This defeats the purpose of using the strongly typed DataSet between Web service server and client. Is there a way not to send the XSD?

Hi Lomiarz,

It looks like your ASP.NET worker process (ASPNET account on Windows XP)
doesn't have the right permissions.

Try granting this account permissions on your Ora Home directory. Read, as
well as execute.
