 - How do I update child keys when I update their string data? I'm new to VB .NET and I've made an Access database with several one-to-many relationships. I want to display the data in a datagrid and give users the ability to edit the database. It's simple enough to import the database into a DataSet and display the string data that the keys point to using SQL INNER JOIN statements, but once the data has been updated, how do I use the new string data values to update the child keys that need to be returned to the database? Do I need to import the parent tables in their entirety and make a relational dataset? If anyone could point me to some example code that would be very helpful.

 - Problems with Password Protected Access DB I can access a password protected mdb file just fine when I write a VB dotnet windows application.

 - SP fails, but OleDbCommand does not throw error! BlankI have found a major problem with the OleDb portion of ADO.NET. If you are using it to call a stored procedure and the procedure has an internal error of some type, the sp will fail, but the OleDbCommand object will not throw any type of error. For example, I have a proc that does an insert and I pass in a value for one of the parameters that will cause a foreign key violation. The call the proc will complete but nothing will be inserted. I can create that same insert statement and call it with an OleDbCommand object and will get the error. Other than a return value, does anyone know how to get a call to an SP to throw an error when it fails?????? -- John Mark Howell Tag: Change password programatically for access database Tag: 94980

 - dataset to database not updating http://support.microsoft.com/default.aspx?scid=kb;EN-US;815660 on this online tutorial i have thi line that i do not understand... -------------------------------------------------- To update the original database with all of these changes, pass the DataSet into the Update method of the DataAdapter object. However, before you can call Update, you must set the InsertCommand, UpdateCommand, and DeleteCommand properties of the DataAdapter object. You can manually write SQL and populate these three properties with corresponding SqlCommand objects, but you can also use Visual Studio .NET to generate these three commands automatically. To generate the required commands when they are needed, you must create an instance of the SqlCommandBuilder object and use the DataAdapter in the constructor. If you want to use this method (shown in the code sample that follows), you must have primary key information available for your table. To access primary key information, call FillSchema, and then set the MissingSchemaAction property of your DataAdapter to AddWithKey, or manually set the primary key in your code. -------------------------------------------- I open and created a data binding connection to the form controls using the wizard and i works fine... But i can not make the changes made into the dataSet to go also no the database when i press the confirm button on the form. I used the VS wizard to create the connection, but something must be missing? How do i set the InsertCommand, UpdateCommand, and DeleteCommand properties of the DataAdapter object?

 - DataSet Foreign Key Constraint Error I have a dataset with a parent table and 3 child tables. The dataset is filled and manipulated on one particular web page. During the user interaction one of the child tables can have records inserted,edited, or deleted. Upon clicking save I call the Update method of my dataAdapter mapped to the child table in my db and pass the dataset childtable in as a parameter. I'm getting an inconsistent foreign key constraint error. The error is telling me that a certain child key value(1768) must exist in the parent table. The value I'm being given is the parent primary key of one of the records in my database. The strange thing is upon entry into the aspx page an entirely different parent record and related children records were loaded into the dataset. How am I getting this rogue child record in my dataset for an entirely different parent record than the one I'me inserting child records for? I thought I may be loading my dataset with more child rows than I wanted but my dataset should give the same foreign key constraint error if I try loading rogue child records without the parent record in the parent datatable. Anyone seen this type of bahavior before? I had a hunch that the auto generated SELECT statement appended to the INSERT statement of my dataadapter may be causing the issue so I got rid of it. Seems to have solved the problem, but I would like to know if this truly is the solution, or if I'm missing something else?

 - Binding a combobox to a related DataTable Hi all, I have a DataSet with 2 related DataTables. Here's a simplified schema: Member [MemberID(PK), FirstName, LastName, FacultyID(FK)] Faculty [FacultyID(PK), Name] I have a 1:n DataRelation between those tables named 'Faculty_Member': Faculty(1) ---> (n)Member Now the problem: I have a WinForm for editing the Members. Also important is that I'm using a DataView on the Member-table. I'd like to have a ComboBox for choosing the Faculty a Member belongs to. I don't know how to bind the combobox so it will display Faculty.Name, use Faculty.FacultyID as value and then propagate the changes made into the Member.FacultyID. Also when the CurrencyManager of the DataView changes its position I want the combobox to display the Faculty of that member. How do I get this to work? Can I use the DataRelation at all for that kind of purpose or do I have to populate the combobox manually? I'd be glad about any suggestions.

 - Updating Database I need help. I am trying to figure out the best way to uodate a database with information. I am gathering my information from text fields on a form and I just want to insert them into the database that I have. I tried builing the SQL string and then adding it to a command object and then executing a non query but .NET does not seem to like this approach. I have been reviewing the various VB .NET manuals and they seem to want me to fill a dataset. Can this be done without the dataset? Would I be better off just sticking with regular ADO for this kind of operation? I was trying something like the following and getting errors: Dim cn As OdbcConnection cn = New OdbcConnection("dsn=CMI;uid=;pwd=;") strSQL = "INSERT INTO Customer _(FirstName,LastName,Address,City,Province,PostalCode,Email)" strSQL += " VALUES ('" strSQL += "'" & Replace(txtFirstName.Text, "'", "''") & "'," strSQL += "'" & Replace(txtLastName.Text, "'", "''") & "'," strSQL += "'" & Replace(txtAddress.Text, "'", "''") & "'," strSQL += "'" & Replace(txtCity.Text, "'", "''") & "'," strSQL += "'" & Replace(txtProvince.Text, "'", "''") & "'," strSQL += "'" & Replace(txtPostal.Text, "'", "''") & "'," strSQL += "'" & Replace(txtEmail.Text, "'", "''") & "')" cn.Open() Dim cmdInsertCustomer As New OdbcCommand(strSQL, cn) cmdInsertCustomer.ExecuteNonQuery() cn.Close() Can anyone suggest a way I could accomplish what I need to do here.

 - sqldatareader compare to server side read only cursor in ado Hi, SqlDataReader must be connected to the database in order to bring data. this is like server side cursor read only in ado. the point is that in the SQL Profiler, when my code is running over the records in ado recordset with server side cursor, i see SQL activity for each move in the record. in SqlDataReader i don't see the same activity in the profiler for each record. can someone explane why is the difference and is the DataReader really a server side cursor?

 - Error: Can't create child list I have a master table named keywwordsets and two child tables keywords and searchphrase. I created relations in the xsd file: ID to KeywordSetID in both cases. In the underlying Access database these same relationships are also defined. The KeywordSet table is bound to 3 textboxes and a checkbox. The child tables are bound to grids. The datasources are the dataset dsWKS1 and the datamembers are the relations KeywordSets.KeywordSetsKeywords KeywordSets.KeywordSetsSearchPhrase I tried several times to make a datamember that didn't start with the KeywordSets table (somehow this seems wrong to me) but the compiler rejected all my attempts.

 - dataset.writexml and diffgrams, not writing well formed xml Hello, I am using vb.net and trying to write a local copy of a strongly typed dataset as a diffgram when the user is offline, so that when they connect to the server again their changes can be sent back. I am writing the diffgram using: dataset.writexml(filename,xmlwritemode.diffgram). If I load the original data from the server, then write it as a diffgram, then exit, then run the program again (this time offline) and load the diffgram, all works fine. However, if I then write the diffgram again, from the same dataset but this time with the local copy of the data (which has just been loaded from the diffgram), then exit, then run the program again and try and load the diffgram I get an xmlexception with errorcode "Xml_badnamechar" and the message "The ':' character, hexadecimal value 0x3A, cannot be included in a name. Line 9983, position 49." This is presumably because one of my field names includes a ':' (which I now suspect may have been a mistake!). But why does it not cause a problem the first time round, and is there anyway of making writexml encode the offending characters? I would be very grateful for any help, Edward Murray Tag: Change password programatically for access database Tag: 94892

 - Problem with DataView.Add() : the new item isn't shown/focused in Hi, I have a real serious problem I can't figure out myself. Here's the pretty plain scenario: I have a DataSet with one table. I created a DataView on that table. I have a Listbox bound to the DataView to select items to display and edit in a couple of TextBoxes. So far everything is fine. Now I'd like to add a button that allows the user to add an item to the list. In the event handler of the button click I call the Add()-method of the DataView. Unfortunately nothing happens to the UI visually. The selected item in the list stays unchanged. I can select the newly added 'empty' item manually at the bottom of the list though. But the TextBoxes still show all the details of the last selected 'real' item. When I press the add-button I would like to have the newly added item (row) selected in the ListBox automatically and all the TextBoxes blanked out. That's exactly the result that I got when I dropped the DataView and bound all controls to the DataTable of the DataSet directly. I just don't understand it. But I need to use a DataView so I will be able to filter the data that will be displayed. Oh, I might mention that there is NO RowFilter set on the DataView (yet) that might prevent the newly added row from showing. Can somebody please help me?! I would really appreciate it. PS: I also already tried to use the Add()-method of the underlying CurrencyManager. It's still the same :-( Best regards, Lorenz Tag: Change password programatically for access database Tag: 94890

 - Tracking Down Source of Constraint Exceptions I have a dataSet that loads in Xml Data that could be created externally. It is using the DataSet.ReadXML command. Constraint errors can occur as a result of the data being passed. When a Constraint exception occurs is there any way of getting more information as to which table, row within the data set is causing the problem or which line of the XmlFile being read is causing it to occur as opposed to just sorting through The xml file to find the cause???

 - Typed datasets & sorting with parent-child data... I have a two-table typed dataset. For the sake of argument, the tables are "tbl_Parent" and "tbl_Child" (no, these are the real names). What I want to do is show a sorted list of all the parents & within each parent, a sorted listed of the children. However I'm not having much success sorting the internal list... For example, I have an ASP.NET Repeater that I can bind to the tbl_Parents table to... but to sort it, I used a DataView. Then, with in the ItemDataBound in that repeater, I'm grabbing the specific DataItem (in this case, a tbl_ParentRow) and getting the child rows... but I can't sort the children. I'm sure this is possible, I'm just not approaching it the right way. Ideas? -AC Tag: Change password programatically for access database Tag: 94887

Hi there,

I was wondering if it is at all possible to programatically change a
password for an access database using VB.NET? Do I use a specific SQL
command to perform such a task? Thanks in advance.

Hi Nick,

First of all, I would like to confirm my understanding of your issue. From
your description, I understand that you need to change the Access database
password in VB.NET using a SQL statement. If there is any misunderstanding,
please feel free to let me know.

As far as I know, we can use ALTER DATABASE PASSWORD statement to achieve
this. We can put the statement in an OleDbCommand and execute it. For more
information, please check the following links:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnacc2k/htm
l/acadvsql.asp
http://support.microsoft.com/?kbid=304915

This statement seems to apply to Access 2000 and later version. HTH.
