 - 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: Dotnet Viewers Tag: 145696

 - 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: Dotnet Viewers 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: Dotnet Viewers Tag: 145637

 - 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: Dotnet Viewers Tag: 145636

 - .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: Dotnet Viewers Tag: 145632

 - Add Connection Dialog box I'm using VB 2005 Express and am trying to set up a new SQL Server connection using another server on my network. My problem is when I go to set up a new connection and the Choose Data Source dialog box comes up only MS Access and SQL Server database file choices are there. I'm stumped as to how to address this limitation. I can connect and do what I need through ADO. Net to any server but cannot set a persistent Data connection... seems pretty odd. I appreciate your help Thanks Paul Tag: Dotnet Viewers Tag: 145620

 - Dataset designer uses username as schema I've created a typed dataset. I've dragged some tables onto the dataset. When configuring the corresponding table adapter, Visual Studio is generating SQL script code such as... CREATE PROCEDURE DOMAIN\UserId.StoredProcName AS... The userid is being used as the schema, it is invalid syntax. My userid is set to use dbo as the default schema, why is dbo not being used in the script? Using SQL 2005, Visual Studio 2005.

 - how to insert NCLOB value with System.Data.OracleClient Hi, I am trying to use an OracleParameter object to insert a value into an NCLOB column - the value is stored as a string variable in c# and contains non-ansi characters. from what I can understand, I need to set the OracleType property which also sets the DbType property in the superclass if I set the OracleType to be nvarchar, some values seem to insert Ok but some others give this error: ORA-01461: can bind a LONG value only for insert into a LONG column it doesn't seem completely dependent on the length of the data but I presume this is the underlying problem. so I have tried setting OracleType = OracleType.NClob. however, this gives ORA-01084: invalid argument in OCI call any idea how what I am doing wrong? FWIW i'm connected to 10g rel 10.2.0.1.0 and my code looks like this: IDbConnection conn = new OracleConnection(); conn.ConnectionString = "..."; conn.Open(); IDbCommand cmd = conn.CreateCommand(); cmd.CommandText = "INSERT INTO xxx (xxx) VALUES (xxx, :1, xxx )"; IDbDataParameter param = cmd.CreateParameter(); param.ParameterName = ":1"; param.Value = "xxx"; ((OracleParameter)param).OracleType = OracleType.NClob; param.Direction = ParameterDirection.Input; cmd.Parameters.Add(param); cmd.ExecuteNonQuery(); Thanks Andy Tag: Dotnet Viewers Tag: 145574

 - Create Diffgram Based on 2 Different XML Files or Data Sets I have an xml file that my application downloads on a periodic basis. I also have a dataset based on this that is used in the application. At present, the application takes the new downloaded xml, creates a data set from that and merges it with one in use. The ultimate goal is to have the update of the primary data set trigger change events based on only data that has changed (updates, additions, or deletions). I am thinking that I need to generate a diffgram based on the current data and the newly downloaded data and then apply that to the current dataset. Is this the propper approach, and what is the best way to do this. I am seeing some postings regarding an XMLDiffPath tool, but they are several yeares old. How is this done now?

 - LINQ to SQL, over ASP.NET, DataContext.GetTable trouble Hi, Working with LINQ to SQL over an ASP.NET application (VS2008, .NET 3.5) while calling "MyDataContextInstance.GetTable<MyTable>()" it produces sometimes the following exception: "an item with the same key has already been added" I think is some trouble about concurrency or async calls (MyDataContextInstance is an static variable). Could it be a problem related to ASP.NET application lifecycle management? or... a LINQ to SQL (DataContext) bug not supporting concurrency? Thanks in advance for your time. Néstor Sánchez A.

 - How to move table definitions? What is the easiest way to move table definitions between various databases? For example: if I have a excel spreadsheet with column headers, how can I move the table definition (excel seems to be able to detected data types like dates and integers and strings) to MSAccess or SQL server or MySQL? I was going to interrogate the data set for the column types and use ADOX to create the table definitions. The data set won't give me primary key and foreign key information though. Is there an easier way? Thanks, Siegfried Tag: Dotnet Viewers Tag: 145546

 - Best way to reinvent bulk insert? Which is more efficient: a long series of SQL INSERT statements or deserializing a dataset from XML and saving it to the table? If I fill a dataset with current sample data and serialize it to XML, can I expect to use that as a template to subsequently populate the table in the future? This way I can keep the XML under version control as well. What function to I call to save a deserialized data set to a table? We have been using bulk insert with sqlcmd but that is difficult to debug and is specific to SQL Server. Tag: Dotnet Viewers Tag: 145540
