    - How to retrieve TimeSpan from typed DataSet? I keep getting an InvalidCast exception when trying to do this: DataRow row = dtP.Rows.Find(projectID); bakInterval = new TimeSpan(); bakInterval = (TimeSpan)row[colBI]; //colBI is a string const Error Message: "Specified cast is not valid". As far as I know, the rowBI column is in fact a TimeSpan. Below is how the dtP table is created. The last line shows colBI created as a TimeSpan type. DataTable tblProject = database.Tables.Add("TableProject"); DataColumn project_ID = tblProject.Columns.Add("Project_ID", typeof(Int32)); project_ID.AllowDBNull = false; project_ID.Unique = true; project_ID.AutoIncrement = true; project_ID.AutoIncrementSeed = 1; project_ID.AutoIncrementStep = 1; tblProject.PrimaryKey = new DataColumn[] { tblProject.Columns[0] }; tblProject.Columns.Add("ProjectName", typeof(string)); tblProject.Columns.Add("BackupInterval", typeof(TimeSpan)); I can cast ProjectName to a string, and Project_ID to an int, but I can't cast BackupInterval to a TimeSpan. What am I doing wrong? Thanks in advance. Tag: instant client + odp.net Tag: 125819

    - Is this a Bug in Visual Studio 2005?? Try the following in VS 2005: Add a SQLCommand object to a Windows Form Set the connection to the Northwind Database Change the "CommandType" to "StoredProcedure" In the "CommandText" property, select "CustOrderHist" from the combobox. The "Parameters" collection property does not get populated. Clear the "CommandText" property and press Enter. Manually type in "CustOrderHist" in the "CommandText" property and press Enter. The "Parameters" collection now gets populated correctly. Why doesn't the Parameters collection get populated when a stored proc is chosen from the combo box? Is this a bug or am I missing something?

    - Column 'Column' does not belong to table 'Table' Hello I have a dataset which is successfully being filled. However whenever i try to access a givewn row of one of the tables in the dataset i get the error "Column 'ContactId' does not belong to table 'SalesAgent'" Except that it does and if i use an ordinal reference i can access the value of the column. If i print the schema sure enough the column is called ContactId. I have also noticed that if i hover the cursor over the contactrow i can access a treeview which lists all columns in the contactrow and then tells me that none of them belong to table salesagent. This was a conversion from 1.1 to 2.0. Any ideas? Thanks Lenny Tag: instant client + odp.net Tag: 125791

    - c# - AcceptChanges - What's it used for? Hi, Can anybody tell me when you would use DataSet.AcceptChanges. If you use it, then all the new records are reset to be seen as original records (unchanged), and hence cannot be updated into the datasource. Therefore I've been using the update method which does both Accet changes (rebuilds the row numbers in the data table) & saves to datasource. I can understand RejectChanges as this would discard new rows before the update, but why AcceptChanges? When would you use it? Thanks for any ideas on this Ant Tag: instant client + odp.net Tag: 125787

    - Moving data from Access to SQL Server using ADO.NET Hi, I was looking for long time for a fast and reliable way to upload Access table into an empty SQL Server table. Finaly I came with a way that seems to be working fine but I'd like to get confirmation from this group that there are no hidden problem going that way. In short I used system.data.OledbConnection with Jet provider to get DataReader to the Access source and fed the system.data.SqlClient.BulkCopy object with that reader to bulk upload the changes. Here is a sample code: Can someone point out if this method will work in "all" cases ? What are the hidden problems I should expect ?

    - What's up with the VS.NET 2005 Dataset Designer? Why has the VS.NET 2005 dataset designer changed so much from the 2003 designer? The 2003 designer gave you so much more power over the way the dataset was represented in XML. It seems like the designer has gone to a much more Database-centric approach, rather than an XML-centric approach. While I can understand a need for this for users who use datasets as way to work with remote databases, we typically use datasets as convenient ways to store structured data on the local disk (using the ReadXml and WriteXml commands on the dataset). In our case, a traditional database is never involved. As a result it is very nice to have control over how the XML is stored. It seems like all this control has been removed or hidden from the VS.NET 2005 dataset designer. Here's what I've found: - You can no longer define if columns are stored as elements or attributes. It seems to default to elements (which result in larger XML files) - Nested elements/tables are cumbersome. You can define a nested table as a DataRelation but it requires a common key between the two tables. Seems like a foreign key in the child element is repetitive and a waste of space. In the 2003 designer you could just drag a child table unto a parent table and be done with it. - I always liked the ability to set the table primary key and have the Dataset code generator create a function called "FindByXXXX". VS.NET 2005 doesn't seem to do this when you use a dataset generated by the 2005 designer. Is there a way within VS.NET 2005 to get these features back? The 2005 XSD designer seems to still have all this, but I can't seem to find a way to convert the XSD file into a dataset. In 2003 you could right click the screen and select "Generate Dataset". Where has all this gone???? -alpha Tag: instant client + odp.net Tag: 125777

    - login routine with information returned from database Hi i am creating a login routine that i have overloaded and wondered how i could return some data back to my program or even if i am going about the right way of achieving what i want to do. The function takes some parameters the server name, the database, the username and the stored procedure name the other overloaded function takes the same parameters plus a password and two optional parameters for the username and password input parameters for the stored proc defaulted at @username and @password. Then the function opens a data reader using cmd.executereader if the datareader has rows then it returns true if not it returns false. It is meant to be a generic login dll for use in my apps either windows or asp. Sometimes i may need to return the full name of the user or one or two other parameters how could i do this i was thinking about having some public property's but i am unsure of how to go about setting them. I keep getting an error invalid attempt to read when no data is present. When i call dr.hasrows does this then empty my datareader i remember from my course manual that a datareader is readonly forward only?

    - Data Validation and Import Strategy I would appreciate some input and advice on the following situation. I have a number of data files which I need to place the data into my database. Much of the data in the files are, of course, related and I need to validate the data before putting it into the database. An additional requirement is that I need to report what lines in these files are incorrect and kick those out with a reason. My idea is to do the following. Create a data set of the database schema, verify the data by attempting to load the data into those tables, and report any errors. Then, import the correct data into the database using bulk copy. In .net 1.1 it seemed that DataSet/DataTable couldn't handle large amounts of data, and I heard that .net 2.0 has fixed this. So, perhaps I can load all of the data into the DataSet at once, else, I can either commit data to the database X amount at a time. OR, I could validate the data, and remove the data from the DataSet. Then import all the data into the database that is valid. Does anyone see a problem with this or have a better solution? Thanks.

    - DataBound ListBox selects first item I am fairly new at developing, but have decided to implement an application that uses a comboBox to populate a listbox, Both comboBox and ListBox are DataBound. For example: if a type of car is selected in the comboBox the list box will show that type and the user can then select from the listbox which car to look at. The problem occurs in the listBox, it selects the first item in the listbox, on Form load. I assume the selectedIndex changes while it is populating. I have tried setting the SelectedIndex to -1, but it does not appear to make any difference. Is there a way to stop the selection automatically, so that the user can make the selection.

    - Problem with ODP.Net and TNSNames I am using asp.net (Framework 1.1) with Oracle 9i and ODP.Net version 9.2.0.401. I am developing using a local copy of IIS version 5.1. When I use a connection string to connect to Oracle utilising a data source in my TNSNames.ora file initially everything is fine and I can connect without any problem. After about 2 minutes as I move from page to page and requery the database I seem to loose the connection with the error "ORA-12154: TNS:could not resolve service name". I am using the following line in my web.config file to create the connection string:- <add key="Main.ConnectionString" value="data source=dev.ora;User Id=xxxx;Password=xxxx;persist security info=false;Pooling=true;Connection Lifetime=120;Min Pool Size=0;Incr Pool Size=1;Decr Pool Size=1;Max Pool Size=20;"/> Interestingly if I change this to the relevant data source entry within my TNSNames file:- <add key="Main.ConnectionString" value="data source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=xxxxxx)(PORT=xxxx)))(CONNECT_DATA =(SERVICE_NAME = dev.xxx.xxx.xx)) );User Id=xxxx;Password=xxxx;Pooling=true;Connection Lifetime=120;Min Pool Size=0;Incr Pool Size=1;Decr Pool Size=1;Max Pool Size=20;"/> Then I do not have any problems. I would prefer to use TNSNames rather than entering the datasource directly. Has anyone any ideas why I loose the connection? Tag: instant client + odp.net Tag: 125743

    - .net and DB Data layer : Best Practice I am converting an app. from PHP to .net. I know that you can create an xsd and then have the system generate code to load data into a dataset. I assume that you use this and an a data adapter to talk to the DB. However, is this the "optimal" or recommended way to add, update, etc. information? Or should one create code to accept the data and then pass it to a stored procedure? I do not dislike the adapter way, but I can see that it could introduce problems and the programmer can loose control which may cause errors or data integrity violations. Comments?

    - Sychronize Key between Database and Dataset on Insert Hi, I'm sure this has been asked many times before, but I haven't had a lot luck finding an answer; not googling the question right. So I apologize before hand. I have a TableAdapter whose insert command uses a store procedure. When I call TableAdapter.Update() passing in the table the database gets updated, but the primary key in of the DataTable doesn't match the one in the database. I've read some responses about selecting the "Refresh Dataset" option under Advanced Options in the Dataset Designer, but I only see that option when using a SQL statement and not a stored procedure. I prefer to ues the stored procedures. Is there an option I can configure on the TableAdapter that I missed? What's the simplient way to handle this?

    - Search button to filter a Dataset Hi all, I hope someone can help with this relatively simple problem. I am building a timesheet application using ASP.NET C# with Visual Studio 2003.As it is only a protoype application, my database has been made in MSDE. I have a 'View Resources' page, the purpose of which is to show all employees, taken from that table in the database. This works fine, up to a point. I have a DataGrid, which is done with a DataSet and a DataAdapter. I now want the user to be able to 'filter' the DataGrid, using a text box for input, and a 'search' button. I have tried different ways of doing this but can't get it to work. I imagine that it is achieved by running some kind of different SQL statement (with a % LIKE % operator) in the btnSearch_Click method, and re-binding the Data Grid after the filter has finished. So for example the user could enter 'John' in the 'First Name' text box and click 'search', and the Data Grid would refresh accordingly with all records LIKE 'John'. My Page_Load code looks like this currently ------------------------------------------------------------------------- this.sqlDataAdapter1.Fill(this.dsResources1); DataGrid1.DataBind(); sqlConnection2.Close(); this.DataGrid1.PageIndexChanged += new System.Web.UI.WebControls.DataGridPageChangedEventHandler(this.GridPageIndexChanged); -------------------------------------------------------------------------------------------- Hope someone can help, I'm sure the btnSearch_Click method is where I need to put the code.

    - Typed datasets 3-tier application We are in the middle of a project that requires both a web GUI and web services. We have elected to go with a 3-tier (data, business, presentation) model using typed datasets as the data layer. We are not using either the sql data source or the object data source on the page, just rolling our own, old school style. The customer(s) will are all business partners with reliable and fast connects and there is no expectation of ever having a consumer direct option. We are posting this since we have been unable to find any real examples of this type of implementation and are looking for help in poking / filling the holes. Who knows you may be looking for an example, so here goes..... Data Layer Straight vs2005 generated typed datasets for all updatable data access. For read only reporting and display data access we will use untyped datasets. We have not had much success with data readers so we will shy away from them if possible. You can generate a strongly typed dataset so we won't bore you with the details. Business layer Accepts requests from pres layer or web service layer and interacts with the data layer. Any necessary validation, conditional enforcement, or other business logic is checked / applied. In many cases this is just a pass through if we have done a good job with required fields, getting and setting nulls for value types, and client side validation. In others, especially calls from the web services, there will be a bit of processing going on in the Biz obj. This layer is not creating a business object from the typed dataset, only interacting with the datasets as they pass through. Presentation layer Is "Aware" of the typed datasets, but has no idea where they come from, and is limited to reading data from them and plugging data into them. All data access must go through the biz layer, even if just a pass through or simple lookup. The pages are smart enough to do most of the required field checking and input validation, however any conditional biz logic or other complex enforcement is left to the biz object. We are currently storing the typed datasets in the viewstate. As mentioned before the users all have reliable connectivity. We don't load any data that we are not willing to put on the page so there are no data security issues. All of our updatable datasets are dealing with 1 or 2 rows data so they don't really bloat the viewstate all that badly. We have implemented several pages and so far it seems to be working. The typed dataset is living up to the billing of reducing both design and run time errors due to the increased use of intellisense. The performance so far is great and we are already reaping the benefits of reusable code blocks, both in the data and biz layers. So there it is - shoot it down before it multiplies. We think we are on the right track - but since we built the track - what else would we think? I would be glad to provide some code samples upon request Thanks in advance.

    - Dynamic SQL generation is not supported against a SelectCommand that does not return any base table information Hi, I have data access tier designed in such a way, just by changnging application settings, same lines of code is made to work with both MS SQL Server or MS Access. Code works fine with MS SQL Server. however while executing following code lines on MS Acess ds = new DataSet(); oAdapter.SelectCommand.CommandText = this.SelectCommand; oAdapter.SelectCommand.Connection = oConn; if (idbType == (int) ApplicationConstants.DBType.SQLServer) { oAdapter.DeleteCommand = sqlCommandBuilder.GetDeleteCommand(); oAdapter.InsertCommand = sqlCommandBuilder.GetInsertCommand(); oAdapter.UpdateCommand = sqlCommandBuilder.GetUpdateCommand(); } else if (idbType == (int) ApplicationConstants.DBType.Access) { oAdapter.DeleteCommand = oleCommandBuilder.GetDeleteCommand(); oAdapter.InsertCommand = oleCommandBuilder.GetInsertCommand(); oAdapter.UpdateCommand = oleCommandBuilder.GetUpdateCommand(); } return oAdapter.Fill(ds); It throws out the following error System.InvalidOperationException was unhandled Message="Dynamic SQL generation is not supported against a SelectCommand that does not return any base table information." But i have defined primary keys on all tables in Access databasel, just like what i have in MS Sql database. Just to avoid this error i can not use explict Insert, Delete or Update command for Adapter as the same lines of code (above) has to work with 15 diff tables. Any suggestions to this?

    - Problem with ADO.NET and dao pia in the same project I have a wierd problem working with ADO.NET and DAO PIA in the same project - it seems that ADO.NET is causing the DAO objects to be destructed. Once I open ADO.NET connection, the DAO objecucts seems destructed (at least thier native part) and I get Unhandled Exception: System.Runtime.InteropServices.COMException (0x800A0D5C): O bject invalid or no longer set. The funny thing about it is that it happened only in release build when run outside of the VS 2005 IDE. The repro code is below. Any idea how to work around this problem ? Thanks, Einat using System; using System.Text; using dao; using System.Data; using System.Data.SqlClient; using System.Runtime.InteropServices; namespace AccessDataTransfer { class Program { static void Main(string[] args) { String Sourcedbstr = "c:\\1.mdb"; String DestConnectionStr = @"Data Source=localhost;Integrated Security=SSPI;Initial Catalog=pubs"; String TableName = "Foo"; //dao connection dao.DBEngineClass engineClass = new DBEngineClass(); dao.Workspace workSpace = engineClass.CreateWorkspace("WorkSpace", "Admin", "", WorkspaceTypeEnum.dbUseJet); dao.Database Sourcedb = workSpace.OpenDatabase(Sourcedbstr, Type.Missing, true, null); dao.Recordset SourceRecordSet = Sourcedb.OpenRecordset(TableName, Type.Missing, Type.Missing, Type.Missing); //ADO.NET connection that invalidate the DAO objects SqlConnection DestConnection = new SqlConnection(DestConnectionStr); DestConnection.Open(); Now manipulate dao object and fails TableDef tblDef = Sourcedb.TableDefs[TableName]; //fails here } } } Tag: instant client + odp.net Tag: 125687

    - Using Widows Authentication and accesssing SQL with SQL Authentication Hi I am working on an application with .NET 2005 and SQL server 2000. I am using windows authentication for my web application authentication and trying to connect to the SQL server with SQL authentication credentials. My web.config reads as follows: web application Authentication: <authentication mode="Windows" /> <authorization> <allow users="*" />   </authorization> <identity impersonate="true" /> SQL Authentication: <connectionStrings> <add name="DevDBConnection" connectionString="Server=MyServer;database=MyDB;uid=MyUser;pwd=MyPwd;" providerName="System.Data.SqlClient" /> </connectionStrings> MY IIS directory security is set to "Integrated Windows authentication". I am validating the user againt the Active Directory for authentication and reading the user details and groups which works fine. But trying to open a connection object fails. I am getting a "{"Cannot open database requested in login 'MyDB'.

    - tranferring data from Access to SQL Server Express I created a VB.Net 1.1 application that iterates through all the tables in any basic Access 2000 database passed to it and generates the same table structure in a SQL Server Express database. The structure is created fine (with minor data conversions from one to the other, e.g. yes/no --> bit, memo --> text, etc). My problem now is transferring the data over from Access to SQL Server. I thought it would be a fairly straight forward process, but I don't think I thought it through that well, unless I am missing something. I currently have the code retrieving a DataTable object from Access one at a time. The only way I can think of now to get the data into SQL Server is to create a DataAdapter for each table in SQL Server and create an InsertCommand for each of adapters. This will involve iterating through all the columns of each table, determing their data types and length, and then adding the parameters. Is this what I have to do, or is there a shorter method? Perhaps dump the Access table to a file and then use bulk import utility (bcp) for example??? Hmmm... Thanks for any help, Marcus *** Please respond to this group.

    - Strongly Typed Dataset (1.1) and DataRelation for Navigation Only I am trying to create a strongly typed dataset in .NET 1.1 and am having a problem with adding relations via the design time XSD editor. When you generate a relation at runtime, you have the option of specifying "createConstriants". Normally I would want to have constraints on a relationship, but I am working on a dataset where I only need it for navigation. I can't create a relation with the designer that does not enforce them. Any one know how to do this? Thanks, Eric Marvets MVP - Developer Security Tag: instant client + odp.net Tag: 125656

    - How to persist an ADO recordset from Sql Server into Access Is there a simple way to persist a recordset from a SQL Server db into a table in an Access database, for example DAO allows a "select * into tablex in 'c:\externaldb.mdb' from..." Or is a disconnected recordset the way to go, but then how do I persist this back into another table in an Access database or even a file?

    - Transactions with TableAdapters in ADo.Net 2.0 I have a VS2005 C# winforms app connecting to SQL2005. Having discovered the limitations of the new TableAdapter implementation, and the fact that if I use System.Transaction on updates to a DataSet with several related tables then MSDTC is automatically invoked, I've followed advice from this newsgroup and elsewhere to implement my own methods in the TableAdapter classes to apply a SQLTransaction object to each command (much as I used to do with DataAdapters in ADO 1.1). This seems to work very well, but I'm puzzled by the fact that when I trace the events in SQL Profiler I do not see any BEGIN TRAN or COMMIT statements, even though if I artificially induce a rollback the transaction is definitely completely rolled back as expected. Is there a different communication channel for transactions with SQL2005? brian smith Tag: instant client + odp.net Tag: 125626

    - Changing column order in typed dataset I create a typed dataset based upon a table, using the VS2005 designer. I then add a query to the table adapter with a select statement, changing the order of some columns, and removing others. When I select preview data, I see the columns in the original order of the dataset, with the columns I removed now showing up as empty. This can't be by design, can it? And if so, how can I order the columns? Since I am using stored procedures, I can drop the select stored procedure in the TDS and the resulting column order is correct, but I am now using a different table adapter. Are there any other options? Thanks, David R Tag: instant client + odp.net Tag: 125618

    - Binding to TextBoxes on MySQL with C# Ref: WinXP SP2, MySQL 5.0, .NET 1.1, C# I try to bind columns to TextBoxes. The column data appears in the textboxes, but if modified will not update. My code came from MySQL example, which uses a datagrid. If cols in the datagrid are modified they update fine. The following code: DataTable changes; changes = this.data.GetChanges(); x = 1; this.da.Update( changes ); this.data.AcceptChanges(); yields the error "Value cannot be null", as I guess 'changes' is null because nothing in the DataGrid has changed. So, how to get the TextBox bindings to yield non-null 'changes' FYI: 'data' is a DataTable, 'da' is MySQLDataAdapter Thanks! Tag: instant client + odp.net Tag: 125615

    - can't drag a dataset Hi, i'm a beginner, this is the scenario: i'm using vs2005 and c## Created a win form project. Created a ms database with some tables. created a win form who acts as parent and some others forms that inherits from it, in my parent form a put a label and a group box. Drag a dataset to a inherited form and work fine. The problem: Can not drag any other dataset to another inherited form. I did try dragging from datasource window (typed dataset), from server explorer, dragging a grid control and bindig to a table, but nothing really work. I was triying some options and if i create a new win form i can drag a dataset to it. *** Sent via Developersdex http://www.developersdex.com *** Tag: instant client + odp.net Tag: 125612

    - Connection String will not connect from ASP.NET I have been using the following connection string to connect to sql server from an asp.net page: packet size=4096;user id=xxxxxx;data source=w2k3bspsqldevvs;persist security info=True;initial catalog=xxxxxx;password=xxxxxx It worked perfectly well. I had a week off and now the asp.net page will no longer connect to the sql server. If I create a c# desktop app and use the connection string above then it works. If I create a new asp.net page and use the connection string then it doesn't work. I found a similar message in this group entitled "ASP.NET Connection String" - the solution was to restart the SQL Server. Unfortunately my sql server is in a cluster and never gets rebooted. Any one got any ideas? Thanks Tag: instant client + odp.net Tag: 125596

AFAIK, there currently is no support by any of the Oracle .NET libraries for the Oracle Instant
Client. I think CoreLab (OraDirect .NET) has indicated that they intend to support it in the next
version of their software.
