    - Changes to DataSet not sticking I am currently making the move from ADO in VB6 to ADO.Net. It seems very straightforward, but I have a serious, nagging problem w/ some code I've written. Here's the pseudo-code Instantiate an object of Class WDABase (a class that is used in one of my tutorials to encapsulate some basic DB functions) Fill a DataSet from table Set a DataView with which I will be doing my searches and updates Do the last two items again for a different table Loop a delimited text file Pass an array of values to a procedure to either add a record or update existing records If no rows are found, add a new row Else, update any rows that were found Accept all changes using the DataSet's AcceptChanges method Set my views to nothing Close my database connection I've pasted the code below. I'm stumped! Can one of you ADO.Net jocks easily spot what I am doing wrong? ----------------------------------------------------------------- 'Global Declarations in VB Code Module Dim objAccessDB As New WDABase Dim objDBView1 As New DataView Dim objDBView2 As New DataView Dim objDataSet As New DataSet ----------------------------------------------------------------- 'Instantiate the Access DB object and fill DataSet (imbedded in Select Case logic 'in a procedure) Using objAccessDB 'Set DataView SetABCDataViews() 'Call to SetABCDataViews procedure, which works well 'Revise label MainForm.StatusLabel.Text = "Data Loaded...Processing Data" MainForm.StatusLabel.Refresh() '******* AT THIS POINT...I call a proce that opens a text file and loop through it ' calling the UpdateABCMergeDB for each line, passing it an array ' of values that were read from a delimited file...then I return here ' once the entire file has been read and delt with.

    - Issues w/ using a DataTable with a TableAdapter's Update method I created a TableAdapter (TA) in my VB 2005 project. I tested it to ensure that its CRUD functionality is what I expected it to be. I'm using the TA and its strongly-typed DataTable (DT) in my Wizard. Initially, I populate the DT using the TA.GetData. I pass the DT to a ASCX-styled control that 'pivots' (turns years into columns) the data into a new DataTable (DT2), then binds it (DT2) to a GridView form. I save the original DT in the viewstate. So far so good. When I want to save the data, I compare the values in GridView to the DT that has been retrieve from the viewstate. The DT's rows are modified accordingly. So far so good. However, when I attempt to use the TA's Update method, passing the DT, I get an error about a missing parameter. I'm assuming that the parameter's value is supplied by the field that has a matching name. I've noticed that each row has a value in this field. What am I missing here? Another oddity, perhaps. If don't make an changes in the pivot grid, there won't be any changes to the DT. Why is it that the each row's rowstate is 'modified'? Could this be related my the Update issue? Thanks in advance.

    - IsolationLevel of ReadUncommitted Hi, I was wondering if you could use SqlCommand.BeginTransaction( IsolationLevel.ReadUncommitted ) to speed up a database read, and if so, is it necessary to perform the EndTransaction after the read is complete? Can you use this approach for asynchronous database reading as well? Any suggestions are welcome - my problem is that there are several users who are notified any time a particular table is changed, and they will all try and read the table the moment they are notified, and noticable delays occur (longer than you would expect from the time it takes to get the result set from running the query from the Query Analyzer - not necessarily a fair comparison). Any help would be appreciated. Thanks in advance. Tag: reg datatable Tag: 145789

    - Does a DataView increase the speed of an DataTable.Select ? Hi out there, I use an algorithm which uses different selects in loops and needs some optimizations. I read in a book that when I define a DataView with a specific sort my DataTable.select is faster. (The tables have a primary key and the select is containing these fields). Is it true?

    - Winform sql server app Hi I am new to sql server and need to build a one-many winform app with visual studio 2008 and sql server backend and need some pointers. I have the following questions; 1. If I create the app by creating a relationship between master and child tables in dataset and then dragging the master table and relation onto a form to auto generate everything, would that be a good enough way to cerate the app? If so, what more can I do to turn it into a robust enough app such as error handling etc? If this is not a good way to cerate app what should I instead do? 2. Is there a good book on the subject of vs2008/vb2008 and sql server 2005 specifically, that will me sufficient advise on how to develop the app? Many Thanks Regards Tag: reg datatable Tag: 145783

    - SQL Express Edition We are currently tied between two options. One is to use Microsoft Access 2003 or Use MS SQL Express Edition (Bundled with Visual Studio.Net 2005). I read a documentation Saying that in The Express Edition you can't make a parallel Query etc... Our company is just a small business catering to a maximum of 20 Concurrent Connections on a Database. Is it ok if we use SQL Express Edition? What are the Pros and Cons? We are finding it hard to develop Application using MS Access because of Limited Resources and one thing more we are all new to this technology because we are using Foxpro for DOS 2.6 and Visual Foxpro 7.0. MS SQL 2005 is very expensive and our company can't afford it now. Will you please give me some advice. Do you have sample source codes that implements MS Access VB.NEt 2005 with Parent and Child Tables using DataGridView and having Default Buttons such as Add, Edit, Delete, Find, Save where everything was done programmatically including connection strings, Data Adapter etc... This will really fastrack our Development Process. We downloaded a few but some are not working when we run it our Visual Studio.Net 2005. It is really hard on part to develop since our company is using only Dial Up internet with 56 KBPS Connection. Thanks in advance for your kind support. Tag: reg datatable Tag: 145766

    - DataSet Cascade update is slow Hi, I have a master-detail relation between two tables in a typed DataSet. The relation is enforced by forgein-key relation with update/delete cascade. The user can create a master recorde (the session) and then adds details to the session. Which can be some tens of thousands of rows. Saving the session to the database (calling DataAdapter.Update) never ends for large number of details. I am suspecting the cascade update to take a lot of time. I mean when the new ID of the session is set on all the details rows before saving them in their turn. How can I accelerate this step of cascade? Why setting a field value (the master ID) on some 10 of thousands of rows is that slow? Thanks Tag: reg datatable Tag: 145759

    - Select from multiple tables in typed DataSet Hi, This may be a very silly question, but it has me beat at the moment. How do I select data from more than one table into a typed DataSet? I added a typed DataSet to my project with two related tables, and I specified the relationship between them. What I need to do is execute a query like this: SELECT a.col1, a.col2, b.col3 FROM a, b WHERE a.col1 = b.col1 AND b.col4 IN (@list) The list parameter is a string holding a comma separated (and quoted), arbitrary length list. Obviously I can only define the query on one of the tables in the DataSet - but when I get results back, they only contain columns for the one table. I.e. if I've defined the query on table a, I only get two columns in the result. I can see why this should be the case, but is there a way that I can get a result that contains columns from both tables. Sorry if this is really obvious and I've just missed it.

    - Map data from one DataTable to another Hi I have a DataTable with data which I need to import into another typed DataTable at runtime. The columns in the first DataTable may be different. I have a DataColumnMappingCollection (which the application user creates) which maps the first DataTable column names to the second. The first table may have more columns than I need to import to the second. It's also possible that I may need to convert types from rows in the first table to the second. What's the most efficient way to get the data into the correct columns in the second table? I did wonder about doing something with the DbDataAdapter before filling the first table. However it looked like I would have to query the data twice from the data source. The first time to get the column names and then the second after creating new column mappings. Is this a good idea?

    - Problem getting the right output from my typed dataset I have a typed dataset which I used to generate an export file in XML which is consumed by another program. What I'm having a problem is that some of the elements aren't coming out the way I need them. For example, I have a section (which is a child table for my record) which keeps track of security accesses. The problem is, I need the output to come out like this: <SecurityAccess> <Access>AA</Access> <Access>BB</Access> </SecurityAccess> Instead, it comes out like this: <SecurityAccess> <Access>AA</Access> </SecurityAccess> <SecurityAccess> <Access>BB</Access> </SecurityAccess> How do I get it to come out the way I want it to? The schema fragment that defines this section: <xs:element name="SecurityAccess" minOccurs="0" maxOccurs="1"> <xs:complexType> <xs:sequence> <xs:element name="Access" type="AccessType" minOccurs="1" maxOccurs="unbounded" /> </xs:sequence> </xs:complexType> </xs:element> With Access Type defined as a xs:string with restrictions.

    - Importing a CSV into a Dataset (preferably. with VB.NET 2005) Is there an easy way to import the contents of a CSV text file into a Dataset, preferably using VB.NET (2005)? Here's the clincher - I cannot use code I already found out there that simply splits the lines based on commas in each line, as there are cases where there may be a comma within a string (surrounded by quotes), and I don't want to split on that. Here's the first few rows of the data to give you an idea: "Subscriber Number","Statement Date","Charge Type","Charge Description","Amount" "555-555-5555","02/11/2008","LOCAL AIRTIME, LONG DISTANCE and INTERNATIONAL CHARGES","","$0.00" "555-555-5555","02/11/2008","Taxes","","$8.60" "555-555-5555","02/11/2008","WorldClass Int'l Rate","General","$0.00" "555-555-5555","02/11/2008","BB BIS&BES AddOn","CUSTOM DATA PACKAGE","$(3.60)" I also am not having any luck with the OLEDB examples out there too, as my filename could have spaces in it (for example the current one is "Statement Detail.csv"), and trying to do a "select * from Statement Detail.csv fails every time. Any ideas/suggestions? Tag: reg datatable Tag: 145736

    - Asynchronous database calls Hi Using .NET 2.0, is there anyway of invoking Sybase and Oracle stored procedures asynchronously? The scenario is this: we have some (Sybase and Oracle) stored procedures that are taking a few minutes to run. This means that our middle tier objects are â??blockedâ?? waiting for the stored procedures to return their results. I know I can use a worker thread from the user interface to effectively kick off the time consuming call to the middle tier and database. However, my real goal is to release middle tier resources as early as possible. In other words, I would like to invoke a stored procedure and immediately free up the resources consumed by the middle tier (e.g. database connection). Then, when the stored procedure completes, it somehow signals to the middle tier that the data is ready. I did something similar to this with SQL Server and extended stored procedures, where my extended stored procedure called a COM component and gave it the results. Can this be done in a .NET 2.0, Oracle 10g and Sybase ASE 12 setup? Thanks! Tag: reg datatable Tag: 145732

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 Tag: reg datatable Tag: 145729

    - 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! Tag: reg datatable Tag: 145725

AVL,

How do you figure a user is going to be able to interact with 700000 rows of
data in a grid?
