    - preventing new rows in datagrids when using relations hi, i am using 2 datagrids tied together with datarelations in a dataset. That part works great. i need to suppress the new row on the datagrid but cannot use the readonly properties on the datagrid so i can allow the user to check off on bool columns. I know dataviews can prevent it with allowNew set to false but i can't seem to use dataviews with the relationships thanks al Tag: Cannot generate DataSet from SQL SP in VS 2003 (Biztalk 2004!!)

    - How do I filter a child table through its parent? Hi all! I am trying to apply a filter to a table in a dataset using criteria from a parent table, but I have no luck so far. Having a dataset with tables for Customers and Orders, and a relation between them, I wish to find the highest order for customers in a specific region. Creating a view for Customers filtering them to only display Customers in Region='A' is no problem, but as I try accessing Orders, it is not filtered and so I have no way of finding the most expensive order for the region 'A'. Just using the same criteria on the dataview for Orders does not work, neither "Region='A'" nor "Customers.Region='A'" can be applied to the Orders table. I am actually not interested in displaying this information, I need to use values from the filtered version of Orders for extensive calculations and aggregations, so attaching my dataset/tables/views to any userinterface components won't help. Any ideas greatly appreciated! Tag: Cannot generate DataSet from SQL SP in VS 2003 (Biztalk 2004!!) Tag: 104001

    - RowNotInTableException Using an XmlDataDocument together with DataSet (typed) Doing some loads and ImportNode/AppendChild So far so good, but when I do some ImportNode/ReplaceChild, the problem starts. Code snippet: : XmlDataDocument destinationDoc; destinationDoc = new XmlDataDocument(myTypedDataset); : destinationDoc.DataSet.EnforceConstraints = false; XmlDocument sourceDoc = new XmlDocument(); sourceDoc.LoadXml(aString); XmlElement importElement = (XmlElement)destinationDoc.ImportNode(sourceDoc.DocumentElement, true); XmlElement destinationElement = (XmlElement)destinationDoc.DocumentElement.SelectSingleNode(path, nsmgr); destinationElement.ParentNode.ReplaceChild(importElement, destinationElement); This last codeline throws the RowNotInTableException with additional info: "This row has been removed from a table and does not have any data. BeginEdit() will allow creation of new data in this row" I understand that a row (representing my destinationElement) has been deleted, but it must be deleted because I want to replace it with another element (and thereby another row (and possibly childrows)). Anyone knows how to fix ? Tag: Cannot generate DataSet from SQL SP in VS 2003 (Biztalk 2004!!) Tag: 104000

    - Looking for ideas on how to handle a specific data situation. Hello, I'm looking for options in handling a certain data situation. Data is stored in Oracle. There is a database that contains tables with common information. For example, it contains a table called USER_COMMON. This table has a key field (USER_KEY) and some other fields containing data (login, e-mail, etc) that all applications will need about a user. Then a specific application has its own database and one of the tables there is called USER. This table also has a USER_KEY column with the same value as the column in the USER_COMMON table. I've implemented a layered approach to the data handling. One project has all the data adapter objects, another project has the typed datasets created from the data adapter objects and a third project has the business layer objects which use the data adapter objects and return dataset objects to the GUI layer. This approach has worked great for me when I"m just going against one database. However, now I want to have one object to represent the combination of the USER_COMMON and USER tables. My first thought was "I'll just create a view on Oracle". Then I could create a data adapter from the view and so on. That fell apart because Oracle doesn't allow you to update data thru a view. Next I thought I could put both tables in one typed dataset and do a DataRelation to join them. Again, I can't figure out how to do updates using this approach. Then I saw an article (http://support.microsoft.com/default.aspx?scid=kb;en-us;325688) on creating a dataset JOIN helper class but that didn't seem to have a way to update the backend data either. I noticed this article is quite old so there may be something better out now. I may have missed something but my eyes are glazed over now and I'm looking for some fresh ideas. Any help/tips would be appreciated. Thanks! David. Tag: Cannot generate DataSet from SQL SP in VS 2003 (Biztalk 2004!!) Tag: 103998

    - datagrid paging and XML Hi, Just curious. If you use the pagingsystem delivered with ASP.NET datagrid control ... will the system access the database each time you ask the next page ... or will all data be loaded into a hidden XML-file which will be used when going to the next page. If XML is the answer then ... 1) is it stored in memory or on disk 2) when will the file be deleted ... considering IIS doesn't know how long a user will keep the page in his browser. Thanks a lot. -- Kind regards, Perre Van Wilrijk, Remove capitals to get my real email address, Tag: Cannot generate DataSet from SQL SP in VS 2003 (Biztalk 2004!!) Tag: 103993

    - SELECT Distinct from DataTable, without using SQL Hi, I have the following query I run using SQL: Select Distinct col1 as D1, col2 as D2, count(col3) as CountOf from MyTable group by col1, col2 order by col1 I need to be able to get the same result without using SQL, by querying an off-line DataSet. XPath might be able to do the job, but it's completely new to me and it appears that the data must be in a pre-defined format (i.e. sorted so that "preceding-sibling" can be used). Does anyone know of an XPath query that could do this, or are there methods on DataSet/Table that can achieve this same result?

    - parent, child, grandchild schema I have a database with tables as follows FILM * filmID FilmTitle FilmLength FILMKEYWORD *filmID *keywordID KEYWORD *keywordID *Keyword * denotes primary key Keywords are simply text descriptors for use by a search engine. Films can have multiple keyword associations. ---------- I am trying to build an interface which would display all three tables in datagrids. As the user moves through the items in the FILM (parent) grid, the FILMKEYWORD grid should track the filmID to filmID relation defined in the dataset schema to display the associated filmID keywordID rows in the FILMKEYWORD (child) grid. (this part is actually working!) The KEYWORD (grandchild) grid should track the keywordID keywordID relation in the schema so that clicks on the FILMKEYWORD grid display the corresponding keywords. ------------ I followed a nice walkthrough I found to get the parent/child part of the system to work but the keyword (grandchild) grid doesn't display the keyword when I click in the filmkeyword grid although it shows the column names in the fixed row at the top. I'm also wondering; when I define the keywordID to KeywordID (grandchild) relation in the dataset schema between FILMKEYWORD and KEYWORD, the relationship dialog box will not enable the OK button unless I choose field associations for both keys in the FILMKEYWORD compound-primary-key though only the keywordID actually relates to the foreign key, keywordID, in the KEYWORD table. To fix this, I removed the primary keys in the FILMKEYWORD schema and redefined just keywordID as the primary. This allowed me to define the relationship but I'm thinking it will cause trouble when update time comes. Also, the FILMKEYWORD/KEYWORD relationship doesn't show up as an option in the grid datamember property like the FILM/FILMKEYWORD relationship did. This is probably why the keyword grid won't track the relationship (doh!) I hate to whine but I can't be the only nerd trying to do this and it shouldn't be this hard! Is there a walthrough tutorial for a parent child grandchild system like this somewhere? Tips and hints are welcome! Thanks, Roger Tag: Cannot generate DataSet from SQL SP in VS 2003 (Biztalk 2004!!)

    - DataRelation in DataGrid Hi, I'm using a Dataset containing two tables, e.g. Person, Customer. Table Person has some Fields like PersonId, LastName, FirstName, Adress, etc. My Table Customer has two fields fk_person and CustomerNo. I have an DataRelation with these tables between field PersonId and fk_person. Further, I have added the columns LastName and FirstName to my DataTable Customer, which is connected to the DataRelation. All I want to do know, is to display the Customer table with the fields of the person table in a datagrid. When I bind this DataTable to a dataGrid instance, I can see all the fields I want to see, but I can't edit the fields of the person table, e.g. LastName. Now, I know that binding to a DataRelation is somehow like binding to a dataview. But how can I make my person tables's field writeable anyway ? Any idea, or is it impossible to edit these fields ? Is there another way to connect these two tables in the Dataset ? I don't want to join these two tables in database, because I want to use the command builder functionality of the dataadapter, which only can be used when data comes from not more of one table. Any tips or other ways to go ? Thanks in advance, Patrick Tag: Cannot generate DataSet from SQL SP in VS 2003 (Biztalk 2004!!) Tag: 103974

    - Async Calls to DB does not help in the efficiency department? Hi Guys, I was recently reading an article: http://msdn.microsoft.com/library/default.asp?url=3D/library/en-us/dnservic= e/html/service10012002.asp [Excerpt] "One of the most common types of I/O operations that occur within a Web method is a call to a SQL database. Unfortunately, Microsoft=AE ADO.NET does not have a good asynchronous calling mechanism defined at this time, and simply wrapping a SQL call in an asynchronous delegate call does not help in the efficiency department. Caching results is sometimes an option, but you should also consider using the Microsoft SQL Server 2000 Web Services Toolkit to expose your databases as a Web service. You will then be able to use the support in the .NET Framework for calling Web services asynchronously to query or update your database." It stated that perhaps wrapping an sql call in an async delegate doesn't really provide any performance gains. Is this true? Or does this only apply to webmethods? Maybe I'm misinterpreting what is being said? Regards DotnetShadow Tag: Cannot generate DataSet from SQL SP in VS 2003 (Biztalk 2004!!) Tag: 103944

    - Implementin Three-Tier App. Hi, I'm learning about three-tier programing and i want to implement this in a simple windows forms Application (not web), i'm using an Access 2000 Data Base, the objective of my application is to stores data from cd's into the data base, so i have 4 related tables, ("CdCategories", "Cds","Folders","Files"). I want to use Typed Data Classes, so i made one class for each table and one Typed DataSet for each relation (each of this typed datasets contains a pair of datatables with a defined DataRelation, for example a "Folder-Files" dataset). The problem that i have is that i don't know exactly how to implement all this especially when creating the BLL and the DAL layers.

    - get record count from stored procedure without passing DATA back? Is it possible in ADO to execute a (select) stored procedure, but just return the number of records, not the actual data. My client has some stored procedures which if executed with certain parameters can return thousands of rows.

    - Data Controls or Code I'm fairly new to .NET, so bear with me if this question is naive. But do most developers use the VS data controls for connections, adapters, and datasets, or do you write all that code manually? And if you use the controls, how do you wrap your connection and adapter code so that you can easily switch between SQL Server, OLE DB, and ODBC? I've been writing the code manually, and I'm comfortable with that, but I'm wondering whether I'd be more productive using the Visual data controls.

I write a class for handling general operation to the ACCESS database like query, insert, update etc. And the all static methods. Tag: Cannot generate DataSet from SQL SP in VS 2003 (Biztalk 2004!!)

    - How to update dataset with multiple tables in C#? I create 2 tables, ParentTable and ChildTable. The row in ChildTable is referenced to ParentTable. But after updated and saved to database, the row in ChildTable doesn't refer to the correct row in ParentTable. You can see the following example to get the problems. Is there any good way to update multiple tables by using SqlDataAdapter.Update()? Thank you /* New Rows in ParentTable and ChildTable * * ------ParentTable------ * ID Animal * 1 Cat * * * ------ChildTable------ * ID NAME ParentID * "1 small cat 1" */ /* * But after the new rows saved back to the database, the new rows saved wrongly as: * * ------ChildTable------ * ID NAME ParentID * 1 small bird 1 * 2 small dog 2 * 3 small cat 1 =====> The ParentID doesn't dynamically change to 3 but keep the same as 1. * This makes it doen't reference to the correct row in ParentTable */ ------------------------------------------------------------------------------------ I try to use 2 different ways to update tables. But they both result in the same problem. The first way I use is to follow the update sequence recommended by book: adapter1= new SqlDataAdapter("Select * from ChildTable", con); SqlDataAdapter adapter2= new SqlDataAdapter("Select * from ParentTable", con); SqlCommandBuilder sb = new SqlCommandBuilder(adapter1); SqlCommandBuilder sb1 = new SqlCommandBuilder(adapter2); adapter1.Update(NewDataSet.Tables["ChildTable"].Select(null, null, DataViewRowState.Deleted)); adapter2.Update(NewDataSet.Tables["ParentTable"].Select(null, null, DataViewRowState.Deleted)); adapter2.Update(NewDataSet.Tables["ParentTable"].Select(null, null, DataViewRowState.ModifiedCurrent)); adapter2.Update(NewDataSet.Tables["ParentTable"].Select(null, null, DataViewRowState.Added)); adapter1.Update(NewDataSet.Tables["ChildTable"].Select(null, null, DataViewRowState.ModifiedCurrent)); adapter1.Update(NewDataSet.Tables["ChildTable"].Select(null, null, DataViewRowState.Added)); ------------------------------------------------------------------------------------- The 2nd way is to use 2 SqlDataAdapter seperately to update tables, but still get the same problem : The Child table row "3 small cat 1" is wrong adapter1= new SqlDataAdapter("Select * from ChildTable", con); SqlDataAdapter adapter2= new SqlDataAdapter("Select * from ParentTable", con); SqlCommandBuilder sb = new SqlCommandBuilder(adapter1); SqlCommandBuilder sb1 = new SqlCommandBuilder(adapter2); adapter1.Update(NewDataSet.Tables["ChildTable"]); adapter2.Update(NewDataSet.Tables["ParentTable"]); Please refer to the UpdateTableMethod1() and UpdateTableMethod2() in the codes I provide. ------------------------------------------------------------------------------------ I just put some codes on the website.

    - NullReferenceException in call to DataTable Select I'm trying to use the Select() method on a DataTable but I'm getting a NullReferenceException. Here's the stack trace: at System.Data.Select.Evaluate(Int32 record) at System.Data.Select.FindFirstMatchingRecord() at System.Data.Select.GetBinaryFilteredRecords() at System.Data.Select.SelectRows() at System.Data.DataTable.Select(String filterExpression, String sort) I've found a work-around but I can't explain why it works. The work around is to call the Select() method once first without a filter argument, then to call it again with the actual filter argument you're interested in. Like this: DataRow[] records = ds.Tables["MyTable"].Select("", "C1, C2, C3, C4, C5, ID"); //note the empty string as the filter records = ds.Tables["MyTable"].Select(myFilter, "C1, C2, C3, C4, C5, ID"); //myFilter contains the actual filter value And for some reason the sorting string to the first Select() call has to be the same string that's used in the second Select() call. So doing this wouldn't work: DataRow[] records = ds.Tables["MyTable"].Select(""); records = ds.Tables["MyTable"].Select(myFilter, "C1, C2, C3, C4, C5, ID"); The reason I discovered this work-around is that if you copy and paste the entire call to the Select() method into one of the debugger watch windows, you'll get a message stating the same null reference exception as the value of the expression. But if you replace the filter with "" in the Select() call in the watch window, it will return the correct result as the expression value. Then if you step through the actual code it works (it doesn't throw the exception)! It's like the DataTable needs to be re-initialized before you can call the Select() method, even if you do it in the debugger watch window. Does anyone have any ideas about what's going on here?

    - Optimizing multiple rows storing into Access 2003. Need Help! Hi I am looking for a way to optimize my data storing into an Access 2003 Table (the mdb file I am using is Access 2000 version) oleDbDataAdapter seem to write one row at time even if it receives multiple rows I tried this code below CalBackFunc() <- My call back func is called every second approx { ...... TypedDataSet1.Merge(?? ) //<- My main dataset in updated here if(CycleCount>20) { CycleCount=0; //<- Every 20 times I make an update into the //- database to reduce the I/O stuff MyDt=new MyTypedDataSet(); MyDt.Merge(TypedDataSet1.MyTable1.GetChanges()); <- I copy //the new data here TypedDataSet1.MyTable1.AcceptChanges(); oleDbDataAdapter1.Update(MyDt.MyTable1); <-I make my storing into the database here with 20 rows each time } } This don't seem to work as I want it; I am looking if there is an auther way to store multiple rows in the same time into Access database. Maybe like storing into an xml file and periodically store it back to the database in one shot. Could some one tell me how can I optimize this kind of storing, it would be very healpful.

    - Re: DataAdapter problems... OK I have made a little progress on this.... Seems I was missing: dataset.Tables[0].AcceptChanges(); However, this alone did not fix it.... I needed to manually assign the value from the 'bound' textbox, by doing... dataset.Tables[0].Rows[0]["Name"]=boundtextbox.Text.ToString(); This seems odd to me... as the textbox appears bound to the datatable, but when I change the value, it doesn't seem to be writing back properly.... although a MessageBox.Show(dataset.Tables[0].Rows[0]["Name"].ToString()); shows the correct value... it doesn't have the same (required) effect until I specifically assign the value in code.

    - SQL Server Error Trapping in ASP/ASP.NET I've run into an odd bit of behavior when dealing with SQL Server 2000 and ASP/ASP.NET that I wanted to discuss. The issue I encounter is that in a stored procedure, once a SELECT statement succeeds and returns a recordset, all resulting errors are ignored by ASP/ASP.NET in certain cases (see details below). Wouldn't you expect the ADO/ADO.NET command to fail if the procedure it calls fails? For example, I created a simple stored procedure that is meant to fail after successfully returning a recordset. -------------------------------------------------------------------------- CREATE PROCEDURE spt_TestSqlErrors @ErrMsg VARCHAR(255) = '' OUTPUT AS --SUCCEEDS returns a recordset SELECT 'Test' AS FirstName, 'User' AS LastName --SUCCEEDS but does not return a recordset DECLARE @SelectResults VARCHAR(255) SELECT @SelectResults = FirstName FROM tblUsers WHERE UserID = 12345 --SUCCEEDS but updates 0 records UPDATE tblPerson SET ID=0 WHERE 1=0 --FAILS divide by zero SELECT 12/0 AS DivisionError --SUCCEEDS and raises an error SET @ErrMsg = 'Error Message.' RAISERROR(@ErrMsg, 16, 1) WITH LOG GO -------------------------------------------------------------------------- With ASP.NET Command.ExecuteNonQuery - will return an error (Divide By Zero) Command.ExecuteDataReader - will not return an error (Divide By Zero) Adapter.Fill - will return an error (Divide By Zero) With ASP Command.ExecuteNonQuery - err object does not register an error Recordset.Open - err object does not register an error Use whatever hypothetical situation you like to explain why a stored procedure would return multiple recordsets and would raise an error if the second recordset didn't exist. Wouldn't you expect the DivideByZero or Raiserror to roll up to ASP and ASP.NET in all situations and not be ignored by the ExecuteDataReader or by ASP completely? What do you think?

    - TableMappings Hi, I got a problem by putting 3 SELECT statements in one DataAdatper. I try to build a 'Select' DataAdatper, which only has select command. I put following lines in select commandtext Select * from Orders; Select * from OrderProducts; Select * from Products; I use DataAdapter wizard. DataAdapter wizard will generate 3 tables automatically like Table, Table1, Table2. Then I go to set table mappings like Table --> Orders, Table1-->OrderProducts, and Table2 ---> Products. It seems work find until I try to remove 2nd select. After I remove 2nd Select, my table mappings are all messed up, Table-->Orders, Table1-->OrderProducts. It is wrong. I thought if I remove 2nd Select, 2nd tab mapping should be remove too. In fact, I am wrong. So my question is how to let TabMappings be synchronized when a Select commad is removed.

    - Constructing a Dataset from XML I have an XML file I've created in another application that contains information on files, forms, and job header. My plan is, in my new "consumer" app, to read in this data and work with it, ultimately producing labels for shipping, etc. My planned approach is to construct a Dataset with 3 DataTables from this data: One table for job header; one table for form info; and one table for specific records. Then I want to set up one-to-many relations from the top, down. It's probably the SQL Server programmer in me that I'm taking this approach, am I overthinking it? Should I just stick with a flat DataTable? Would a collection be a better choice? What benefits will I get from the DataRelations? If I set up a DataGrid on my form, can I easily display, say, Job Number | Form Code | Record Filename, etc.? In other words, if I'm not creating a database on some other server, do I benefit by going to the trouble of normalizing the data in this way? I'd appreciate any comments. -- Michael Kellogg Tag: Cannot generate DataSet from SQL SP in VS 2003 (Biztalk 2004!!) Tag: 103835

I have VS.NET 2003 and also have BizTalk 2004 installed on the machine.

Usually it is possible to add a DataSet to a project and then drag a stored
procedure to the design surface to create a strongly typed dataset.
With BizTalk 2004 installed the schema designer comes up as that from
BizTalk and this does not give a design surface to drag and drop to.

How can I make VS show the default schema designer instead of the BizTalk
2004 one so that I can create datasets as before??

Thanks for your help.

Right click the dataset and choose Open With. Then Select XML Schema Editor
but before you click ok, hit the Set as Default Button - This has to be
the most annoying feature that I"ve ever experienced b/c you can't do squat
with datasets w/ the Biztalk editor. Fortunately it's easy enough to fix.
