 - How to connect ADO.NET Entities to something that is not MSSQL Hi, I'm trying to test ADO.NET Entities but the new connections available are only MS SQL drivers. How can I place other providers there? Thanks, Marco Castro Tag: How to join a multi table DataSet with update of a single table? Tag: 145728

 - ANN: OleDBPro and OleDBProNet released for flexible, easy and fast accessing large database recordset Hi, All: UDAParts keeps on improving OleDBPro and OleDBProNet, and has just updated OleDBPro (2.5.0.1) for C++ and OleDBProNet (2.0.0.1) for .NET. The new important updates include: 1. In addition to 32bit regular desktop development, now OleDBPro for C++ also fully supports 64bit, CE and smartphone phone developments. 2. In addition to 32bit regular desktop development, now OleDBProNet also fully supports 64bit development too. 3. Methods FindFirst, FindNext, FindPrev and FindLast are added into both OleDBPro and OleDBProNet for finding records directly on server side with great performance, flexibility and simplicity. 4. A new sample Find added for demonstrating the usage of the above four methods for C++. The old sample RowsetFind for .NET is updated to echo the usage of these methods. The methods FindPrev and FindLast are only found in OleDBPro and OleDBProNet through MS OLEDB technology! Major OLEDB providers, ORACLE Oracle, MS SQL native client, MS client cursor engine, and advantage OLEDB providers support these finding methods fully. Now, our OleDBPro and OleDBProNet provides much more key features than other similar components like classic ADO and ADO.NET providers. See the sites http://www.udaparts.com/oledbpro.htm, http://www.udaparts.com/devguide.htm, and http://www.udaparts.com/oledbpronet.htm. Cheers!

 - Newbie question: Cstr vs toString Hi I have a WinForm app with a bound form. When user enters a value in field rateid I lookup the respective rate amount from a table and assign it to field rate.I am using the DLookup function to achieve this (full code given below). This function returns a value of type object so I need to convert it to string. If I use the function as below (using ToString) it works fine; Me.txtRate.Text = DLookup(<parameters here>).ToString but if I use it with a CStr Me.txtRate.Text = CStr(DLookup(<parameters here>)) and then browse through 2-3 record the form stops showing data in the bound fields. This brings me to question; what is the difference between CStr and tostring that could be causing the above problem? Thanks Regards ======= Function DLookup(ByVal SearchFld As String, ByVal SearchTbl As String, ByVal SearchCriteria As String) As Object Dim Cmd As OleDb.OleDbCommand Dim Reader As OleDb.OleDbDataReader Cmd = New OleDb.OleDbCommand("SELECT " & SearchFld & " FROM " & SearchTbl & " WHERE " & SearchCriteria, DBConnection()) Reader = Cmd.ExecuteReader() If (Reader.Read()) Then DLookup = Reader.GetValue(0) Else DLookup = DBNull.Value End If Reader.Close() Reader = Nothing Cmd = Nothing End Function Tag: How to join a multi table DataSet with update of a single table?

 - Count all records for all tables Hi Experts Hope Iâ??m in the correct thread. Iâ??m using VS 2005 and the .NET Framework Data Provider for Oracle to connect to an Oracle 7 database. All is ok and I can view and run simple SQL like SELECT COUNT(*) AS EXPR1 FROM ADDRESSES Iâ??m trying to write some SQL that will count all the records in all the tables. I have over 600 tables in the Oracle database. Iâ??ve tried SELECT OBJECT_NAME(id) AS Expr1, rows FROM sysindexes WHERE (indid IN (1, 0)) Which works ok when connected to SQL Server but not Oracle.

 - How VS2008 DataSet generated works? Hello, I'm new in .Net world and there is so many info that I'm lost. DataSet is creted by Visual Studio 2008 to handle a FireBird database. Where can I find documentation about how to use theses classes in a better way? What is the most efective way to use it: load table by table from the database and DataSet handles it or is better create a composite query leaving the work to the database and DataSet gets the relationship already done?

 - UpdateRowSource.FirstReturnedRecord not working on .Net 2.0 I have a project that has been upgraded from .Net 1.1 to 2.0 and I cannot get the UpdateRowSource.FirstReturnedRecord of the InsertCommand to work correctly using the System.Data.OracleClient. It works correctly on 1.1 and the DataSet is updated correctly after a DataAdapter.Update, but although the insert happens to the database on 2.0, the DataSet is not updated. My InsertCommand is a stored procedure that gets the next id (primary key) for the tables instance, inserts the new record with the id, and then gets the newly inserted row as an output. The expected behaviour is the DataSet I passed into the Update method is returned with the record containing the new id. Has anybody run into this problem and found a work-around?

 - ADO.net locks out SQL2000 user account under load This is a strange problem to describe so you will have to bear with me! I have developed a web application using c#.net that utilises server side ASPX pages that connect to a SQL2000 database. I have been load testing my application with the Microsoft Application Test Center that comes with Visual Studio 2003, with simulated loads of 10 - 400 users. When I run a test against my web application for upwards of 10 concurrent users I start to get strange results from the database for what should be routine queries. I execute a simple query looking for a row in a table which I know is there (100% certain!) and the query returns the results to a dataset. I then get the first datatable from the dataset and check that the dataset.rows.count variable is greater then 0. Which it always is! I then proceed to look for a column that exists in the table which I specifically selected and an exception is thrown telling me the column doesnt exist in the datatable. This is actually impossible the data is DEFINATLEY there! I can log into SQL Query analyser as the same SQL logon that the ASPX page uses to connect and run the same query and it returns the expected results without error or anaomoly. Once an error of this type has occured, I can replicated it upto 10 minutes after it first has happened. During this 10 minute period I can switch the SQL logon the ASPX uses and it runs fine. As soon as I switch it back to the user on which the error occured it demonstrates the same problem again. After 10 minutes the problem disappears and wont happen again until I apply a heavy load to the server. As an important note, I have now managed to replicate an identical problem with just 2 users trying to concurrently login. Here is the snippet of code iam using to query the database: public static DataSet execute_DataTable(String SQL_Command_String) { String connectionString; connectionString = getConnectionString(@"..\xml_Settings\DB_Connect.xml"); makeConnection(connectionString); DataSet dsResults = new DataSet(); try { SqlDataAdapter dbAdapter = new SqlDataAdapter(SQL_Command_String, dbConn); dbAdapter.Fill(dsResults, "Results"); } catch (Exception exp) { throw new Exception(exp.Message + " " + exp.StackTrace, exp); } finally { dbConn.Close(); } return dsResults; } This function is located in a static class in a class library that compiles to a DLL that is then referenced in my web project. Every time an ASPX page requires to query the database this method is called. When I load test my application a typical session will involve 2000 queries in a very short period of time. This is because I use a recursive c# function for generating a tree that executes alot of SQL queries. Iam really out of ideas here guys , does any one have any ideas? All I can think of is disposing of the dataset when iam done? Thanks in advance! Mike Tag: How to join a multi table DataSet with update of a single table? Tag: 145644

 - ADO.NET EntityFramework and Large SQL Databases Hello. This is my scenario. I am building a WinForm app. I have a 300+ tables databases. My problem comes everytime i have to build my app. it takes forever and i guess the reason is that everytime that i compile, the system is compiling the 300+ entities it just created. i found a bizarre solution to my problem by having another project, a class library project, only for the model. Then i unchecked the Build in the Solution properties so it doesn't get built all the time. That's fine, but for some reason, i cant find the provider class and also i am having other issues. i guess my question is... Is there a DESCENT way to have the Entity model co-existing in peace in my Winform project and do not wait up to 2 minutes everytime i need to build my app (which happens about 300 times a day in test phase) Any hint on this would be higly appreciated Tag: How to join a multi table DataSet with update of a single table?

 - how to identify the OleDb exception without relying on its message I have written the code that allows to work with a password protected Microsoft Access database as well as with regular (not password protected) Access DB in VB. Net. I use OleDb objects. I need to identify whether a current database is password protected, or not. For this purpose, I create a regular connection string with no password set, and try to open the connection. This piece of code is embedded into Try..Catch.. structure. If a database is password protected, an OleDb exception is raised, with the message "Not a valid password". To determine what is the reason of failure to open a connection, I test the message property of the exception. If it contains the string "Not a valid password", then I can conclude that the database is password protected. This code worked fine until we shipped our software to Netherland. I have found that the message is now "Geen geldig watchwoord", and my code stopped working. The question 1: is there a way to identify the particular exception by an universal attribute (like Error number) without relying onto its message (which looks different in localized versions of OS)? The question 2: is there an alternative way to find whether a Microsoft Access database is password protected? Thanks Igor Tag: How to join a multi table DataSet with update of a single table?

 - .net hold query results? Hello, friends, We have a windows service which will query database through a web service every one minute. If there are new records, this windows service will process accordingly. However, if there are no new records for a long time, say 2 days in weekend, this windows service will no longer be able to retrieve new records anymore. Although it still does the query, but return no records. We then have to stop and restart this windows service to make it work again. We believe .net hold query results somewhere, probably in web service. Rather than actually going to the database to query again, it just returns whatever cached in memory. Are we right, and how to solve this problem? Thanks a lot. Tag: How to join a multi table DataSet with update of a single table? Tag: 145632

Hi,

I created a DataSet with this query:

Select cl.*, c.Nome CidadeCli, c.Estado EstadoCli, c.Pais PaisCli, p.Nome
CidadePraca, p.Estado EstadoPraca,
p.Pais PaisPraca, tc.*, di.Nome dvNome, bc.Nome bcNome, cr.Limite,
cr.Bloquear, NomeRegiao,
cv.Descricao cvDescricao, ba.Bairro, ba.Nome_Bairro, au.*, t.Transportadora,
f.Fornecedor,
ce.Nome Empresa_CidadeCli, clt.Cliente trTransporte, clt.NomeCliente trNome,
entr.Nome EntregaCidadeNome, entr.Estado EntregaEstado, entr.Pais
EntregaPais, cr1.Limite Limite1, ac.Descricao acDescricao
From Clientes cl left outer join Cidades c on cl.Cidade = c.Cidade
left outer join Cidades ce on cl.Empresa_Cidade = ce.Cidade
left outer join Regioes r on r.Regiao = c.Regiao
left outer join Cidades p on cl.Praca = p.Cidade
left outer join TiposDeCliente tc on tc.TipoCliente = cl.TipoCliente
left outer join Divulgadores di on di.Codigo = cl.Divulgador
left outer join Bancos bc on bc.Banco = cl.Banco
left outer join Creditos cr on cr.CodCredito = cl.CodCredito
left outer join Bairros Ba on Ba.Bairro = Cl.Cod_Bairro
left outer join Autor Au on Au.Autor = Cl.Cliente
left outer join CalculodeVencimentos cv on cv.CalculoVencimento =
Cl.Calculovencimento
left outer join CalculodeVencimentos ac on ac.CalculoVencimento =
Cl.Acerto_Consignacao
left outer join Transportadoras t on t.Transportadora = cl.Cliente
left outer join Transportadoras tp on tp.Transportadora =
cl.Transportadora_Padrao
left outer join Clientes clt on tp.Transportadora = clt.Cliente
left outer join Fornecedor f on f.Fornecedor = cl.Cliente
left outer join Cidades entr on cl.Entrega_Cidade = entr.Cidade
left outer join Creditos cr1 on cr1.CodCredito = cl.Credito_Consignado

This query has a lot of tables connected but the most important if the
Cliente (Client) table. The foreign tables are responsible to inform the
description of some codes.

My idea was to create this query and have the insert, update and delete
related to the Client table but when seting the DataSet, the option
GenerateDBDirectMethods are not available. Is there a way to fix it? It
should be intersting if VS asked which table should be used in this case.

Thanks,

Marco Castro
