    - adapter manager error handling Hi How can I handle errors in the UpdateAll method for adapter manager considering that it has multiple tables. Its probably easy by using try/catch if only one table has errors but what if more than one table have errors at update?

    - SqlParameter with size=0 I used the SqlDataAdapter Configuration Wizard to generate a new SqlDataAdapter. I used Sql statements and typed a simple "select * from table1" for the sql. In the generated code all the SqlParameters had size=0. WHY? I have done this in the past, very recently in fact, with no problem.

    - TransactionScope and Concurrency? With the typical example of implementing calls that leverage TransactionScope (via a using code block) - would this be "safe" for asp.net web apps? I am finding some conflicting opinions on the net about this issue. Because transaction enlisting is inherent by all calls in the code that executes (within the using block), would User A's rollback cause User B's to rollback too if they both hit at the same time?

    - Binding RadioButtonList to a SQL bit column through SQLDataSource Hi. This seems like it should be easy but its driving me nuts... I have a radio button list like so... <asp:RadioButtonList ID="controlName" runat="server"> <asp:ListItem Value="'True'" Text="Y" /> <asp:ListItem Value="'False'" Text="N" /> </asp:RadioButtonList> I have a SQLDataSource setup to insert this field into a microsoft sql table. The data source line for this field is... <asp:ControlParameter ControlID="controlName" Name="PARAM_NAME" PropertyName="SelectedValue" Type="Boolean" /> And my param in the sql stored proc is... @PARAM_NAME BIT The insert keeps failing however. It is passing in "True" or "False" to the bit param which I believe is the problem. I tried passing in "T"/"F", "1"/"0", etc.... but can't get anything to work. I believe what I need to pass in is a 1 or 0 (ints, not strings), however the way I understand it is the ListItem Value can only be a string. Is there a way to do this? Thanks!

    - How do you make a dataset when you cannot use a database for it? I have a challenge on my job: to make a gridview that depends on a dataset that is not from a database. The reason for this is that there are two gridviews plus some other data that have to be saved to a database all at once. To simplify a little, at the top of the form, the user enters two numbers which describe how many rows each grid has to have. (He also enters some other data). I guess he would click on a submit button once he has those numbers. Then he has to enter all the data in the all the rows for the 2 grids. The grid rows should have EDIT and DELETE buttons. At the end of all this, he enters a password and clicks on a submit button. Only after he does all this can I save the grid information (and the 2 numbers and the other data) to databases. So it seems to me that I can't have each grid with a datasource of a database, because it would be showing what it retrieves with its SELECT statement, which at the start of the data-entry would be no rows at all. The original setup I had was that the user would fill out a row of textboxes and checkboxes, and then he would hit a submit button, and the data would be added to a database, and the grid would reflect the new row added. I repeated this method for the 2nd grid. But I was told that I should have an all-or-nothing operation - either all the grids and other data are submitted (with a password), or nothing is. Is there a way to do this? Thanks, Marvin Tag: Getting Information Schema values column_name,Allow nulls, primary Tag: 145127

    - Problem remoting to SQL Server from a Vista Machine I have a C# .net app that connects remotely to a SQL Server 2005 database on a Windows 2003 server machine sitting in Chicago. It connects through a VPN. Everything works fine when I run the app from a machine running XP Pro SP 2. When I try to run the same app, no modifications, from a Vista Business machine and from a Vista Ultimate machine, (so I am assuming it's a Vista issue) I get the error [DBNETLIB] ConnectionOpen (Connect()).] SQL Server does not exist or assess denied. It is not the SQL Server, because it works from the XP machine. It is not TCP/IP on the Vista machines because I can do everything else, connnect to internet, connect through VPN etc. As it is happening on more than one machine running Vista and not the XP, that is why I am assuming it is a Vista Problem. I can connect to the SQL Server on the Chicago machine by using SQL Server Management Studio Express. That seems to narrow it down to a ado.net issue. I am using the .net 3.5 framework. Any suggestions? BillG Tag: Getting Information Schema values column_name,Allow nulls, primary Tag: 145126

    - Connect to BindingSource with DataMember I've tried to set a BindingSource DataSource property to a DataSet with many tables. Now I try to connect two DataGridView to the same BindingSource, but using two different DataMember (one with the name of one table and the other with another). Everything is working, the two DataGridView controls are rendering well. Everyone has its own cursor, I can change the data and all. The problem is that if I want to use the properties and methods of the BindingSource object I can't specify which table I'm referring to... For example, if I write bs.Position++; which cursor table is going to move? No one actually, as I have already tried...But why can't I specify the which table I want to manage from the BindingSource if the BindingSource is actually capable of working with multipled set of data? Am I supposed to use a single BindingSource object for each table of the database? Thank you for your help cold Tag: Getting Information Schema values column_name,Allow nulls, primary Tag: 145117

    - Add WHERE Clause Dialog Box Doesn't Support Object Source? When configuring a data source for the GridView, I can access the Add WHERE Clause dialog box, which allows me to filter the results based on a particular column's relationship to any of a number of different data sources (cookies, control, form, etc.). However, what I'd really like to do is tie it to a static property of one of my application's classes. Does anyone know why this option does not appear to be supported, or if there's any workaround?

    - Excel and OleDbDataAdapter. How can i ignore blank columns Hi, I have an application, that needs to import excel spreadsheets into a SQL Server database. I am using an OleDBDataAdapter to load (fill) the data into a Dataset. This works fine, when the spreadsheet is formatted correctly. Occasionally, person sending us the file, will put the data starting in column B, not column A. This fails our checks on column count. They also have started in the third row, which messes up the column headings. I Get F1 -F6 for the column headers and only three of the six actual column heading are read in (as data). The other three column headings are read in as blanks. Also occasionally, an extra blank column after the data gets read in. Well it looks blank in the spreasheet, but I'm assuming they have done something to it. Is there an easy way for me to get the DataAdapter to ignore blank columns and rows? At the moment, I'm (in my opinion) quite rightly rejecting the file, but I would like my application to be more fault tolerant and intellegent.

    - BindingSources, BindingNavigators and direct navigation... Hi there: I dragged several fields from a Data Source to a form in the designer.

Here's the problem: I want the TextBoxes show a specific row in the DataTable, say a row with the Name field = "J Lo" (in a DataTable "People"), without having the user navigating through several rows up until he finds this one. How do I position the BindingSource to that specific row, if I don't know it's relative position in the DataTable bound to the BindingSource?.

    - Limit rows in a DataView to those used in a relation with RowFilter? I have a simple DataSet with two tables, ParentTbl and ChildTbl. They each have a ChildId column. They are joined by a relation ParentTbl_ChildId which associates the ChildId column with ParentTbl as the parent and ChildTbl as the child. This DataSet is not based on a database (it is saved to and loaded from XML files) so SQL queries are not an option. I need a DataView on ChildTbl which is limited to those rows involved in a ParentTbl_ChildId relation. I have been trying to achieve this with the RowFilter property, but have been struggling to define the appropriate expression. Some of the variations I have attempted are: m_filteredView->RowFilter = L"NOT(NULL = (Parent(ParentTbl_ChildId1).ChildId1))"; //The view just ends up being empty m_filteredView->RowFilter = L"Count(Parent(ParentTbl_ChildId1).ChildId) > 0"; // Throws SyntaxErrorException with "Syntax error in aggregate argument: Expecting a single column argument with possible 'Child' qualifier." m_filteredView->RowFilter = L"ChildId IN(Parent(ParentTbl_ChildId1).ChildId1)"; //Throws EvaluateException with "Only constant expressions are allowed in the expression list for the IN operator."

    - Underscore ("_") prefix added to my Column Name I manually created a DataTable in a Typed DataSet using the DataSet designer in VS 2008 Pro. One of the Column names is "IN". When referencing this table in VB.Net 2008, the IntelliSense did not show the column "IN" but it did show a column "_IN'. If I tried to reference this column in code using "tablenameRow.IN" I got the build error: "'IN' is not a member of 'app.DataSet.tableRow". If I reference it with "tablenameRow._IN" then I don't get the build error. I have several other 2-letter-capitalized column names in this table such as: "'LT', 'PI' and 'MA'".

    - Trapping nulls for SequetialAccess I have a group of records in a set - usually 5-10 rows. For example ProviderPanel would have several elements. I do this so I can handle the formatting of each value on a case by case basis. A typical scenario would be that before writing any records to either labels or a class, I should try to 'trap' any possible nulls before trying to set them to a variable. This only works with SequentialAccess in a DataReader So, cn.Open() dr = cmd.ExecuteReader(CommandBehavior.SequentialAccess) Do While dr.Read Select Case strGroupLevel Case "PCP" strMeasure = iif( dr("MeasureID") is DBNull.Value, "", (dr("MeasureID") lPerform = iif(isnumeric(dr("Perform"), dr("Perform"),0) Case "......." End Select But if I do this --- I get the ordinal error - "Tryinng to read from ordinal 1 ...etc. I suppose this is because I am doing a 'double-take' on the column with my IIF statment? And it can't read it because it's on to the next column already? Anyhow, how can I go about trapping nulls if I use SequentialAccess in a Reader.

    - Direct navigation to specific rows in a DataSource... Hi there: I need to get the position of a given Row to navigate directly to it, in a form that has a BindingNavigator and several TextBoxes showing each rows details... I dragged the fields from the Data Sources window to the form in the designer, which created the BindingNavigator attached to a BindingSource. As far as I know, the BindingSource lets you move to the first, next, to a position, previous and last row of a DataTable, so, what if I need to navigate directly to a row that has a specific value in a field (for instance, "Carl" in the field "Name" in the DataTable "People"). I suppose I should get the row position within the DataTable attached to the BindingSource, and then set the BindingSource.Position to that position. But how ca I do that?, the DataTable doesn't expose a property that shows the relative position of each row in the table. Moreover, what if the DataSource is a DataView with filters set, how do I get the position of that given row within this DataView? Please, need help...

    - OleDb delays commits and unlocks? I've seen other posts with similar problems, but no solutions. I have two hair-pulling dilemmas that have been frustrating me for months now. Is there no solution? (C#.NET, Framework 2.0, Jet OleDb 4.0) The general goal is to read one MDB file and copy relevant info into another MDB file (copied from an empty template), replacing the old file with the new file. DataAdapters are used only to read (or re-read) the data from the file into the in-memory DataTable. All data INSERTs and UPDATEs are done with OleDbCommand.ExecuteNonQuery(). Problem 1: To retain the original version of the file, the process requires two rename operations. The first renames the original file. The second renames the new file to have the original file's name. Half the files I process do this OK. The other half fail on one of the renames, claiming that the file is still locked by another process. Checking the directory just prior to the rename attempt confirms that the corresponding LDB file still exists when the rename fails and doesn't exist when it succeeds. I've gone so far as to put all the data copying into a separate Main and invoking it with a Process.Start() so that the locking process has to be terminated before I attempt the rename. No dice. Aaaaargh! Problem 2: In the last-called method of the copy process, one new record is written to each of two empty tables. After that, a message is written to a log file, the method returns, and the OleDbConnection is closed. All of that occurs in about a dozen lines of code. This works almost all the time, except on one of my test files. With that file, the first inserted row appears in the output mdb file, but the second one does not! There is nothing particularly unusual about this file; other test files have identical structures. The tables involved are new tables, not present in the source data file, and every test file requires that these two rows be created. No errors are reported by the INSERTs or any other statement; it just doesn't get committed to the table. Double-Aaaaargh!!

    - Saving Data with DataAdapter to Jet DB I am trying to save changes to a dataset using the dataAdapters update method to an Access 2003 DB, therefore I'm using an OleDbDataAdapter to accomplish this. I am using a For/Next loop to change a single column of data in the dataTable, & I know this works. The problem arises when I try to write the changes to the Access DB, nothing happens but the code process properly. I use virtually the same code set in another project writing to a SQL server DB & that works just fine. Is there some issue with OLEDB & Jet that this does not work or that i must do something different? Just for laughs I included a code snipit of what i'm doing. Try Conn.Open() daVoters.Update(dsCommittee, "Voters") Conn.Close() dsCommittee.AcceptChanges() Catch ex As OleDb.OleDbException Conn.Close() MessageBox.Show("There was an error updating the Database" & vbCr & vbLf & ex.Message, "Prep Data", MessageBoxButtons.OK, MessageBoxIcon.Error) End Try BTW I can do this by writing each change to the DB as I change it in the datatable, but this requires me to open & close the connection nearly 1/2 million times (there are over400,000 records in the DB) Thanks Gary Tag: Getting Information Schema values column_name,Allow nulls, primary Tag: 145037

    - SqlCommandBuilder DeriveParameters Ouput Arg gets wrong direction First, I am using the Enterprise Library DatabaseFactory to get a Database object. I have traced the issue down to the SqlCommandBuilder DeriveParameters method. Given a stored procedure args: CREATE PROCEDURE UpdDept ( @KeyDepartmentIdentifier UNIQUEIDENTIFIER, @KEYTimestamp BINARY(8), @NewName NVARCHAR(50), : : @OutTimeStamp BINARY(8) ) Wheh I call the Database.DiscoverParameters (aka - SqlCommandBuilder.DeriveParameters) the @OutTimeStamp DbPArameter (SqlParameter) has its direction set to InputOutput. SQL procedure parameters are either input or output. InputOut is not defined (SQL 2005). Why is the direction set to InputOutput? This requires that I initialize the output parameter.

    - Datatable beginners question: Merge and row deletions... Hi! I'm trying to use merge in order to apply differences to a table. However, I can't seem to get the hang of it. Here's the short version: I got two data tables, one containing one row and one containing no rows. What I'd hoped to do was to merge the empty one into the non-empty one and get a roe deleted event and a deleted row. Is this possible? Maybe I'm missing something simple here? This is my code: using System; namespace DataSet { class Program { static void Main(string[] args) { // Init System.Data.DataTable Old = new System.Data.DataTable("T"); System.Data.DataTable New = new System.Data.DataTable("T"); // Add columns Old.Columns.Add("X", typeof(System.Int32)); New.Columns.Add("X", typeof(System.Int32)); //Making good Old.AcceptChanges(); New.AcceptChanges(); //Add Row to Old System.Data.DataRow R=Old.NewRow(); R["X"]=0; Old.Rows.Add(R); Old.AcceptChanges(); //Merge Old.Merge(New); Old.AcceptChanges(); //Check foreach (System.Data.DataRow Row in Old.Rows) {Console.WriteLine(Row["X"].ToString()+"/"+Row.RowState.ToString());} } } } Lots of Greetings and thanks!

    - how to extract value from LINQ query? Is it possible to extract a single value from the results of a LINQ query with out iterating over the results. For example I have a table in SQL Server: tblExample Type int <--this is a key field Descr nvarchar(5) I would like to get the description (Descr) field something like this in C#: string Description = from Example in db.tblExample where Example.Type = 1 select Example.Descr; I know this query returns an IQueryable and the above query won't compile because of type mismatch. Is there a way to get the string from the database field using a LINQ query? Thanks Tag: Getting Information Schema values column_name,Allow nulls, primary Tag: 145026
