    - 2008 Express Edition missing Data drivers? I just started doing some basic exercises with Visual Basic 2008 Express Edition (Version 9.0.21022.8 RTM, Microsoft .NET Framework Version 3.5) and I do not seem to have what I would call routine data drivers installed. Initially, I only want to connect to a Northwinds db in my local SQL Server 2000 instance but the only drivers available are Microsoft Access DataBase file, Microsoft Sql Server Compact 3.5, and Microsoft SQL Server Database File. I don't need Access and the other two don't seem to create db connections in a manner I am familiar with. What am I missing and how do I add it? Or is it impossible to do 'normal' database connections in the Express version? Tag: DataTextFormatField: {0:d/60} ??? Tag: 144345

    - Wierd error on data set Occassionaly (and its rare, but i think there are repo steps to this, i just cant completely determin them, but here is what I figured out so far) I have a data set (say its called DS) I have three tables... call them people, peoplejunitem and item... peoplejunitem is a many to many junction table between people and items... well say I load one set of information about a person into the data set's tables... ok this person has items in the junction... say I alter the information in the junction but dont commit it to the database... now I go and load another person... but while loading the next person it clears the information in the junction table and the person table and replaces it with the 2nd person... ok I make changes and push the data back to the database... and boom error... zero rows updated when 1 was expected to be... well that one row updates was from the FIRST! person... even though I did a ds.table("PersonJunItems").rows.clear somehow it still thinks it has rows to push! why?! this happens randomly to me! I tested out the T-SQL statements like crazy and they are not at fault, they are return the correct response, but while watching the SQL Server profiler I saw the commands to update the pervious person going through on person 2 to the database... any ideas how to stop this or fix the problem? or anyone ever see anything similar to this? thanks!

    - Returning the id of an inserted record I am writing an ASP.NET application, and am forced to use Access as my database. I need a way to return the id (which is an AutoNumber field in the table I am inserting into) of a record when I insert it. In SQL Server, I am able to use a statement like the following: INSERT INTO tablename (fieldnames) OUTPUT inserted.id VALUES(valuestoinsert) Take note of the OUTPUT inserted.id part of this statement. This returns the value of the field named 'id' for the record that was just inserted. Unfortunately, this technique does not work in Access. Is there any way to retrieve the id of the record that was just inserted when using Access? Any help would be appreciated.

    - How to solve DataSet Designer SQL errors? Hi there, I have writing easy to moderate SQL in the DataSet Designer and Query Builder, using a Jet 4.0 connection to an Access 2003 DB. I am running VB.NET 2005 sp1. As soon as I try to do anything more than the most trivial SQL (e.g. simple JOINs, more than 1 parameter other than in the WHERE clause, etc.), the Designer/Query Builder balks giving SQL parsing error messages. This means that the Fill, GetData() is not set up properly and compiler errors prevent me from running my app. This is despite the fact that the SQL is perfectly fine (it runs in Access) and in some situations it is possible to 'trick' the Designer (ref. link below). Aside from the critical issue of my app not running, I am not able to leverage strongly typed DataSets, and all the useful commensurate objects (e.g. DataTable, data row). I have been promoting this approach within our development teams, but all these problems make significantly reduce confidence in using these objects and the Designer. Nor it is sensible to use a blend of approaches in my app (e.g. trivial SQL through strongly-typed DataSets and the rest explicitly written in code) from a software design/maintenance perspective. If this can't be solved, I'll look at dropping use of the Designer and going back to hand-coded SQL. Any and all feedback that provides solutions to this problem (e.g. is there an update/patch to the Designer?) would be appreciated. Thanks in advance, David Newsgroup posting "Dataset designer and complex Stored procedure" on microsoft.public.dotnet.framework.adonet http://groups.google.ca/group/microsoft.public.dotnet.framework.adonet/browse_thread/thread/9c0a1938b49329ea/68917fe53b75058c?lnk=st&q=%22dataset+designer%22+sql+error#68917fe53b75058c Tag: DataTextFormatField: {0:d/60} ???

    - OleDbCommandBuilder insert query will not work? dataset to Access I am trying to take a very strangely delimited text file and put it into access. So far I was able to get the text file into a dataset and figured from there I could get it into access. I am trying to use the code below but the insert query(oledbcommandbuilder) just will not work. I am working with a blank access database and I am able to get the table and the field names in the database(with a primary key just set ot the first row). I just cannot get the rest of the data. I get an error that there is incorrect syntax in the insert query. Can someone please help! I've been all over the site reading a buch of different things and tried to just write inserts for each row but cannot get that to work either. Thank you!

    - Need some advice on my Deployment Pkg Hello. Using XP Pro w/SP4 and VS 2003. I wrote my program with the connection string and the path for loading the Maps as follows: C:\MVB.NDbProJim\Ch7\ROE6AllRecords2\Maps. The Maps sub-directory containes all 116 Maps of the Lots and also the ROE6.mdb database. But when I deplay this app to my other PC it gets an error that this path is invalid so it cannot even load the database. Since the MSI installs this package to C:\Program Files\Microsoft\ROE6 I decided to have the Maps subdirectory relocated to this Path. I had to change (in my program) the Connection String and all the 116 paths for it to load the Maps but it now works just fine on the other PC. I must have missed something because it is unreasonable to have to keep the support files at the same location on my PC as the installer is going to use on the target PC. Any words of wisdom to get me straightened out? TIA, Jim Tag: DataTextFormatField: {0:d/60} ??? Tag: 144279

Since its a web application I use a stored procedure to get the results.

    - IIS ASP.NET 2.0 Not creating a connection pool nor re-using I need some help! I have a webapp in ASP.NET 2 running on 2003 R2 that doesn't seem to want to bring up a connection pool. When I run a trace on the DB server I can see Audit Logoff and Audit Logon between query batches, which leads me to believe that this is occurring. This is a replacement platform for our current live systems, so I have just tried to build everything as similarly as possible throughout. The main difference is that the DB server is now SQL2005 SP2 whereas before it was SQL2000. I haven't read anything indicating that this would be the cause, but I am very open to ideas. The connection string I am using is: Application Name='Live';pooling=true;Min Pool Size=1;Max Pool Size=1000;database=DB1;User ID=USER ;Password=PASSWORD;Server=live- db1; I cannot find any way to verify information on connection pooling working, other than by using SP_WHO - which does appear to show an idle connection or two from the webapp, but like I say, I can see the connections being torn down and back up every batch from the profiler trace. The reason I'm investigating this is that the application is serving pages incredibly slowly when they have to hit the database, but I've tried running the query batches directly through MSMS on both the DB server and App servers, and they are very fast - much faster than when run via .NET. This connection latancy is the only thing I can put it down to at the moment. I'd welcome any insight. Jon Tag: DataTextFormatField: {0:d/60} ??? Tag: 144266

    - Attempt on SqlConnection.BeginOpen I have a need for a SqlConnection.Open that times out in an predictable matter (i.e. if the server does not answer, I do not have to wait for TCP or NIC timeouts to find out). The "Connection Timeout" in the connectionstring will not help, as this only applies to the connection to the SQL Server, not to the actual TCP port. Therefore I have had a crack at it myself, and would appreciate any constructive comments on the implementation. The method BeginOpen(SqlConnection,int) will take an SqlConnection and a timeout (in ms), and will try to open it. If it for any reason cannot, it will return within the specified timeout. If there is an exception in connection before the timeout occurs, it will throw that, otherwise it will throw a custom Exception. There is an 4-5 ms overhead by doing this, but I'm willing to sacrifice this for a predictable timeout. Any comments appreciated... private void BeginOpen(SqlConnection connection, int msTimeout) { // Start timeout timer here, it includes all work done in this method. // This assures that this method uses no more than msTimeout to complete DateTime connectionAbortTime = DateTime.Now.AddMilliseconds(msTimeout); // Transfer ambient transaction to thread Transaction currentTransaction = Transaction.Current; // Save the thread exception (if any) Exception threadException = null; // Signifies that we could connect and communicate with the database bool connectSuccess = false; Thread workerThread = new Thread( delegate() { try { Transaction.Current = currentTransaction; connection.Open(); // This might hang indefinatly connection.ChangeDatabase(connection.Database); connectSuccess = true; } catch (Exception ex) { threadException = ex; } } ); workerThread.IsBackground = true; // Make sure application tears it down when it exits workerThread.Name = "SqlConnection.BeginOpen"; // Start work and wait for the thread to finish or it times out workerThread.Start(); while (connectionAbortTime > DateTime.Now) if (workerThread.Join(1)) // Check if thread is finished break; // For some reason, the connection could not be opened, throw an exception if (!connectSuccess) { if (threadException != null) // Encountered an exception before timeout throw threadException; else // Either timed out OR did not have time to save exception in threadException throw new SqlConnectionTimeoutException("Could not connect to server within timeout"); } } public class SqlConnectionTimeoutException : Exception { public SqlConnectionTimeoutException(string message) : base(message) {} } Tag: DataTextFormatField: {0:d/60} ???

    - ADO.NET query execution much slower than SQL Management Studio I have a stored procedure that when called from SQL 2005 Management Studio takes less than one second to execute. The same SP, when called from .NET code takes about 13 seconds. I am using a SqlCommand object with CommandType set to StoredProcedure and I am passing arguments through the parameters collection. I have tried using a SqlDataReader and a DataAdapter to retrieve the data, but both are equally slow. From stepping thru the debugger, I know that the specific statement that takes a long time to execute is either reader.ExecuteReader() or dataAdapter.Fill(dataTable), equivalently depending on the method I tried. I did a trace in the Profiler, and got nearly identical result for either method of .NET SqlClient Data Provider. Here is an example: EventClass: RPC:Completed CPU: 13390 Reads: 559475 Writes: 0 Duration: 13496 Binary Data: (a long hex value) When I copied the TextData (SQL Statement being executed) from Profiler into SQL Management Studio, I get the following trace: EventClass: SQL:BatchCompleted CPU: 437 Reads: 9998 Writes: 0 Duration: 440 BinaryData: (empty) (Immediately prior to this there is a corresponding SQL:BatchStarting trace, with empty CPU, Reads, Writes, and Duration columns.)

Could someone please advise me if I can speed this up somehow? Thanks Regards Tag: DataTextFormatField: {0:d/60} ??? Tag: 144203

    - re-order a dataset Hi, I have a dataset (vb.Net 1.1) that I need to go through and re-order based on the data. I'm wondering if there is a nice relatively automated way to do this, but I kind of doubt it. There is not currently a single field to use in a DataView's order by parameter. The data has two fields that decide the order, node_id and parent_id. The parent_id is the node_id of the row above. If there is no corresponding row to the parent_id then we have row 0. I've messed around a little with looping through the table and I haven't found any elegant (or even not ugly) solutions. Two options that come to mind are cloning the table and copying the rows in order, probably making multiple passes. Another would be to add an "order" column and populating that as I loop through and then use a dataview to order the rows according to that field. Anyone got any better solutions? Could I create a recursive DataRelation to do this? I'd love to hear any ideas! Thanks! Matt Tag: DataTextFormatField: {0:d/60} ??? Tag: 144202

    - Getting command from LINQ query I want to get a DataReader from a Linq Query so I wrote this Extension Method public static IDataReader QueryToDataReader(this System.Data.Linq.DataContext ctx, object query) { IDbCommand command = ctx.GetCommand(query as IQueryable); command.Connection = ctx.Connection; command.Connection.Open(); IDataReader reader = command.ExecuteReader(CommandBehavior.CloseConnection); return reader; } Sometimes it pukes because the Query passed in is a Type System.Collections.Generic.IEnumerable<Application> not an IQueryable. Query comes back as a IEnumerable when I call a sproc that returns after a select statement, even though the return type is defined in the datacontext. If my sproc returns a TABLE object, the Query comes back as a IQueryable. I don't understand why I get IEnumerable sometimes and IQueryable others? Is their a way to get my function to work in both cases? Tag: DataTextFormatField: {0:d/60} ??? Tag: 144192

    - Creating table in Access using C# Hello Group I have made an application that can create Mail Merges with Word. The application creates a WordTemplate and set the Document.MailMerge.OpenDatasource's filename to a text (tab spe.) file. Containing all fields and data to merge with. I would like to change the MailMerge.OpenDatasource's datasource to an Access database instead. In another table i have a list of fields that can be used in the mailmerge. These fields can change from time to time, and therefore i will have to change the table that i used as the MailMerge datasource table. So: I'll need to first Delete the table - easy - just Execute the SQL "DROP TABLE [tablename];" Then create the table with the columns matching my merge fields.. How can i create a new table in Access 2003 using C# and Visual Studio 2005 Kind Regards Johnny E. Jensen Tag: DataTextFormatField: {0:d/60} ??? Tag: 144183

    - Getchunk & Appendchunk When I used VB6 & ADO I used GetChunk & AppendChunk to get/save large image data to SQL Server. In ADO.Net that is not available but I found the below link and it describes what to use as an alternative. Looking at the code I don't see how the data in saved/retrieved in "chunks", is it done natively in ADO.Net? If not, how should I do that now? http://support.microsoft.com/kb/q309158/ Regards, Dan Tag: DataTextFormatField: {0:d/60} ??? Tag: 144176

    - Tables and columns name can contain accented words? In my language, Italian language, we have words with accent, for example "città" or "perchè"; can I create tables or columns in sql server with names that contain letters with the accent (i.e. "à" "è" "ì" "ò" "ù")? Is this absolutely not recommended? Or is it an acceptable practice? Thanks in advance. Best regards. Tag: DataTextFormatField: {0:d/60} ??? Tag: 144175

    - Encrypting config files as part of a VS build event Is it possible to create a post build event to encrypt my config file (which holds my connection strings)? The reason I would like to do this is that while we are developing I would like the developers to be able to see/modify the connection strings appropriately, but when we do a release build and deploy the application and config file to a target machine I want the config files (or at least the connection strings with the file) to be encrypted. I realize this can be achieved within the code, and then place the resulting encrypted config file under source control, but any changes to one or more connection strings would be a burden (ie. recontructing the original file, making the changes, then re-encrypting) Cheers Justin Tag: DataTextFormatField: {0:d/60} ???

    - Null Values eliminates the row? I have a TableAdapter linked to an SQL Server 2000 table. Some of the cells have null string values. In VS2005, I can preview the data linked by the TableAdapter in design mode, and all fields are displayed - even the ones with cells containing null values (they just show "null" in the cell). When I run my application, I create a DataTable and use an SqlDataAdapter and fill it using the TableAdapter. To search my data, I use the DataTable's Select method; however, any row that contains a null value will not show up in the DataRows that are returned. Has anyone ever encountered something like this? Why is this happening, and how do I get around it? Tag: DataTextFormatField: {0:d/60} ??? Tag: 144167

    - SQLOLEDB error I have a remote desktop running SQL (MSDE) connecting to an SQL 2005 server. I do insert and update commands to get the data from one to the other in a VB.NET application. All commands run w/o any issue except for one. That one command is pulling the most data from the biggest file, but other than that it is of the same format as other commands that are working. When I run the command (it is inserting data onto the laptop from the server for data that doesn't exist on the laptop), I receive: Index #0 Message: The operation could not be performed because the OLD DB provider 'SQLOLEDB' was unable to begin a distributed transaction. LineNumber: 2 Source: .Net SqlClient Data Provider But, other commands on the same types of tables (both have identity columns as the key), the insert works fine. I have checked everything, and it is only this table causing an issue. Could this error occur because of a timeout?

    - deleting rows with SQLCommandBuilder I have a task in an ASP.Net page that I think ought to work, but doesn't. It's fairly straightforward. It's an event scheduling site, and I want a user to be able to delete an event. When he clicks the delete button, it posts back to the page with the event id for the deleted event in the query page, and then tries to delete the rwo with an SQLCommandBuilder object. The code looks like this: string qstring = "Select * from Schedule WHERE EventNumber = " + Request.QueryString["EventID"]; System.Data.SqlClient.SqlDataAdapter da = new System.Data.SqlClient.SqlDataAdapter(qstring, MyConnectionString); System.Data.DataSet ds = new DataSet(); da.Fill(ds); if (ds.Tables[0].Rows.Count == 1)//Verify that it returned exactly one row. { DataRow dr = ds.Tables[0].Rows[0];//Select the only row. System.Data.SqlClient.SqlCommandBuilder bldr = new System.Data.SqlClient.SqlCommandBuilder(da); ds.Tables[0].Rows.Remove(dr);//Remove it da.Update(ds);//Update the data set. Response.Redirect("~/allevents.aspx"); } I can verify that the correct dataset is being loaded. It has one table, and that one table has one row. When I call "remove", I can verify that the row leaves the dataset, so that ds now has one table with zero rows. I call Update, and I expect to delete the row from the database, but it doesn't. How do I use the CommandBuilder object to do the delete? Tag: DataTextFormatField: {0:d/60} ??? Tag: 144161

Hi over there,

I've got a DataBoundField in a GridView which name is (both gridview-column
and the column in the database) "TimeInMinutes". And I want another column,
that displays the hours, means the same value as in the TimeInMinutes-Column
divided through 60.
I tried to achieve that with the DataTextFormat field, but I've got no luck.
Is that possible anyway, or do I have to do that by manual by code?

DataTextField: TimeInMinutes
DataTextFormatField: {0:d/60} ???

How can I achieve that I've got another column in my grid view,
that is not existent in the database, but visible in the gridview,
with the value of the database-column "TimeInMinutes" displayed in hours?

any help appreciated,
cheers,
Markus Kofler
