    - Anyone have a DAL Generator? Hello everyone, Anyone out there have a DAL Generator Utility for sale for free that mimics what happens in the IDE designer when you drag a dataadapter onto a component? I like what MS did here, I just don't like the instantiation of all the objects on New(). They Do: Sub Initialize() da1 = new dataadapter da2 = new dataadapter sqlconn = new connection(someconnectionstring) selectcommand1 = new command .... I want to do readonly property da1 as dataadapter get if m_da1 is nothing then m_da1 = new dataadapter m_da1.connection = GetConnection 'Add transaction support if m_intransaction then dim cb as commandbuilder .... 'Add event handlers addhandler m_da1..... I have 40 tables, that is a lot of copy and paste, and too many chances to get it wrong and wind up chasing redherrings. Plus if I make and schema changes, I would have to manually correct the changes in my DAL. I have been playing with creating my own generator, and realized that they is way too much I don't know and understand about what goes on to make a generic tool nor do I have the time to get the tool to a point where I can use it for my application. I spent 4 days manually setting up my DAL more consistent with a format that I wanted. Now the business has come back with some additional changes and I must begin this arduous process again.

    - Batch Statements I have used simple batch statments with C# (ans SQL Server 2000).for example: string select = "select model from cars where id = ?;select * from trucks where model = ?"; where ? is a parameter whose value i have before running the bach statment. I was wondering if it possible to use the value retuned in the first statement for the where clause in the second in the statment?

    - DataAdapter with different SQL's Hello, Created dataadapter select with this command "select * from emp where empid IN (123,456,789)"; Filled and sent dataset to remote client. lost original dataadapter Remote client works with the dataset and sends it back Created a new dataadapter select with this command "select * from emp where 1=2; (effectively a null set) populate the update/insert/deletes commands on the dataadapter based on the 2nd above select Called the Update method of the dataadapter. All changes get affected to the database. Question 1 : Can/should i create the dataset with one select command and at time of update create another select command based on a different sql. (i use this method as when i pass the dataset to the remote site i dont pass the parameters used to create the original sql, so at time of return i dont know/unaware of the original sql). Question 2 : Does this mean that dataadapter works in such a way that it needs only to know the end table & fields without knowing the original data associated, i.e. the dataset set has all the intellegence of old rows/newsrows contained in it.

    - Rowfilter on child recorsd only works with Fill Hello everybody, I have a dataset containing two related tables : Master, Detail. I have used the designer to create a form with two DataGridView. I want to filter parent records so that only those which don't have child records are listed. In the Form_Load, I have created a DataView (dv) with filter : "ISNULL(Count(Child.ID),0)=0" (where ID is the primary key of Detail). I then Fill the datatables : Master, Detail. I then set the Master DataGridView's datasource property to dv. The problem that I have : When the Form is launched, the filtering is correctly done. Now, if I had a row in Master, then add a child row to Detail, the parent row in Master is still there !!! Does the rowfilter only work at Fill time ? It doesn't work with creations/deletions in Master !! Is this a known bug ? I would prefer have this solution work that the workarounds described in the article Q321896 !!

    - Hierarchical data Hi I'm a VB6 developer tasked with taking a VB6 application and turning it into a .NET application. I'm just doing a bit of reading up at the moment... The VB6 application does a lot of queries returning hierarchical ADO recordsets, sometimes this goes as far as 4 chapters deep... This data is not simply bound to a display control, but the data programmatically iterated through and either the data manipulated or other tasks stared based on the values found. I'm after a quick "beginners" tutorial for handling hierarchical data and manipulating it in a VB.NET environment. Any suggestions? All help greatly appreciated.

    - BindingContaxt I am trying to insert a new record into a sql table, that has a field that is a key field. Before I can insert the record I get a message when the statement with the '***' is executed. is there a way to code around this??? MESSAGE: "System.Data.NoNullAllowedException: Colume 'taskid' does not allow nulls". I know this. What I do not understand is how the 'BindingContact' really works. Some of the code follows: CODE: DataRowView drvDetail; DataView vueDetail; public void EditDetail(CurrencyManager cm) { try { LoadData(); cbServices.DataSource = dvServices; cbServices.DisplayMember = "service-description"; cbServices.ValueMember = "service-nbr"; drvDetail = (DataRowView) cm.Current; vueDetail = drvDetail.DataView; *** this.BindingContext[vueDetail].Position = cm.Position; *** txtSON.DataBindings.Add("Text", vueDetail, "service-order-number"); txtTaskID.DataBindings.Add("Text", vueDetail, "taskid"); txtServiceDesc.DataBindings.Add("Text", vueDetail, "task-desc"); txtCompDate.DataBindings.Add("Text", vueDetail, "complete-date"); txtServiceCost.DataBindings.Add("Text", vueDetail, "task-cost"); - Norm Bohana Tag: How to change the value of timeout in program Tag: 116465

    - Emergency! Too Busy A Connection! Hi. I have a problem with an OLEDBConnection object that is supposed to serve for a number of clients that need data from my Access(mdb) database. These clients are placed in different threads and try to load data from this connection. The problem is that when the connection is retrieving data for one of them, another one may ask for data. This throws an InvalidOperationException with the following message: "ExecuteReader requires an open and available connection. The connection's current state is Open, Executing." I fully understand its meaning, but what can I do to solve this issue? I tried a delaying loop, checking to see if the exception occurs again in the loop, and repeating the operation again. Although I used Application.DoEvents (you know what that does) , but a loop takes all the CPU time available, and it seems to me that the whole operation becomes very very slow and surprisingly, memory consuming! Any one got an idea? Thank you all. Tag: How to change the value of timeout in program Tag: 116464

    - transaction with unknown nbr of commands Using vb.net for code behind on a asp.net application. I need to run a number of sqlcommands, based on user input. The commands need to run as a single transaction. The commands are all stored procedures. How do I do this? I was thinking that I could build an array of the sqlcommands, but I do not see how to do it. I looked at arraylist, but still not sure. Maybe the question could be stated as: When I run a sqlcommand in a transaction, does the sqlcommand need to persist, or can I just reuse it to run another stored procedure within the same transaction?

    - Textbox DataBinding I don't fully understand control binding in c# programs and wonder if someone could clarify things for me. I have two related tables ... Parent: USERS (names) Child: USER_CONTACT (telephone numbers, etc) To the child table I've bound several textboxes as follows ... myTextbox.DataBindings.Add("Text", ds.USERS, "USER_USERCONTACT.FIELD_NAME"); All of this works great. My problem is updating the datasource with changes made to the textbox values. Specifically, the routines below successfully pass updates to the datasource just once. After that, in spite of making more edits, the routines don't pass changes back to the datasource. Here are the main events in the code ... BindingContext[ds.USERS, "USER_USERCONTACT.FIELD_NAME"].EndCurrentEdit(); daUSERS.Update(ds.USERS); daUSERS.Fill(ds.USERS); daUSERContact.Update(ds.USER_CONTACT); daUSERContact.Fill(ds.USER_CONTACT); Since my controls remain bound through the update and refill I assume that maybe "EndCurrentEdit()" has ended my editing session and, for additional editing, I need to somehow "begin edit." It's at this point that I realize the greater problem is my not having any idea what I'm doing! Thanks in advance for advice. Tag: How to change the value of timeout in program Tag: 116428

How can this be done? Can someone please point me to a corresponding tutorial? I've been searching through MSDN but couldn't find anything appropriate. When I use the SqlDataAdapter to read more than one query, all the tables get names different from the query source table name. How is it supposed to store it's data back into the database then?

    - Speed issues with ADO.Net I've converted an old VB3 program that loops through the lines of a text file, then uses that info to write to a database. I use mostly OLEDB DataAdapters, DataSets, and DataTables and Rows to insert/update the database. The problem is, this is extremely slow (with one extremely large file, the old program completed in 9 minutes, while the new program took 1 hour 9 minutes!). I'm considering replacing the use of dataadapters etc. with just SQL commands using an OLEDBCommand. Is this the best alternative to increase speed? This is an extremely large, old program that calls different subroutines based on the line read from the text file. Basically, in each sub, I'm creating new DataAdapter, DataSet, and DataTable and Row objects, and using them. Tag: How to change the value of timeout in program Tag: 116380

    - Unchecked checkbox windows form Hi: I'm sure this question has been asked before but I can't find the answer. I have a windows form with a checkbox. It's bound to a BIT field in sql server. I let the wizard create the dataadapter and the stored procs in the database. If the box is unchecked when I insert a new record, it leaves the field in the database NULL which throws an error when I try to load the record. How can I pass False or 0 to the stored proc? Is there a setting somewhere? To tell the truth, I have a lot of checkboxes so I was hope I could change a setting instead of hand code all the bidings for it. I set the default value in the table to (0) but still shows NULL or grey box in the table when my form inserts Thanks RK Tag: How to change the value of timeout in program Tag: 116371

There does not appear to be any replacement. Is this possible?? I was using this in a number areas in my asp app and when I have gone to upgrade I can't seem to find any similiar functionaility - There must be something out there? I noticed that datalist has an Eval - is this similiar - it appears to evaulate things at run-time - could this be used as a replacement. I can't believe that it is impossible - you are meant to be able to create web controls - and if I am correct that the datalist has an eval, than it should be possible to buid Eval functionality into any control - just can't find anything on this one.

    - Are DataViews thread safe? I know DataSets are threadsafe, but what about DataViews from the DefaultView accessor? Here's the situation: ASP.NET application; DataSets in the Cache; Each session gets a DataView from each DataSet via DefaultView, applies a filter to that DataView, and displays the result to the user. From what I understand, if two threads grab the same DefaultView from the same DataSet, and each applies a filter to it, the data displayed to both users will be the same (it will be what is allowed by the last filter applied). Is this true? Right now, when I grab the DefaultView, I Copy() the DataTable before. The DataTables might contain a million or so entries, so this could bog stuff down in the extreme case...

    - Concurrency Issues Autonumbers Hey Folkes: I a general question regarding autonumbering. I see a lot of posts with people having trouble with inserting records with autonumber fileds. I see people suggesting Scope_Identity() and @@IDENTITY and ways to prevent each other from stomping all over each others parent ID. I was woundering, why not immediately do an da.update(DS) after an insert just to get parent and foriegn keys in? Then begin editing the record. Then noone else can get that ID while your filing in all the fields. You've already inserted the record. At this point, your only edit an existing record. Unless there is something I'm missing, you shouldn't even have to Ds.Clear() and da.fill(DS) if your using @@IDENTITY because the DA now has the actual parent ID upon update. I know it's an extra round trip to the data source but is it realy that costly on the network? Especialy if your using SP's. Is there something I'm missing or is @@IDENTITY the answer to my question? Also, I have a question. I've been cheating a bit. I've been using txtChildMyID.Text = txtParentMyID.Text to populate text fields bound to the foriegn key fields to insert the correct ID number in the child table. So far it's been working in a 5 user environment. My sqlDA's and DS's and storedProc's were generated using the wizards. I can't figure out how to get the ParentID from the storedproc to pass it to the param for the child's. I tried SET @MyIdent = @IDENTITY or SET @MyIdent = Scope_Identity() but my app just throws an error. System Error with no other description.

    - Changing a field in the SQLDataAdapter to allow null values. Hi everyone, I am trying to set some fields in a table to a null value on purpose. I'm using the ADO SqlCommand class and setting Parameters for the fields that I want to be null. cmd.Parameters("Field1").value = DBNull.Value This seems to be working fine. The output fields show as <null> in my table. Now my problem... The fields that I am setting to null, were originally set in the SQL Server Table as not allowing nulls. In addition, I have an SQLDataAdapter that was created before I made this change (to allow nulls in the field). My App now crashes when it attempts to Fill the SQLDataAdapter, giving the error ""An unhandled exception of type 'System.Data.ConstraintException' occurred in system.data.dll Additional information: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints." The SQLDataAdapter obviously doesn't like my new <null> value field. So how do I fix this? I don't see any properties that relate to constraints associated with the DataAdapter. I'd just bite the bullet and re-create the SQLDataAdapter(s), but it's used in several DataSets (and related to other tables) and I'd prefer not to have to re-do all that. Any suggestions? Is this error coming from the DataAdapter or from the DataSet? BBM Tag: How to change the value of timeout in program Tag: 116331

    - How2 Flush to Disk DataSet.WriteXML(FileName,XMLWriteMode.WriteSch VB.Net 2003 Windows Form Application. A user session consists of long transactions (15- 30 minutes) where data is stored locally in memory and then submitted to the server at the end of the transaction for permanent storage. The problem is that if something goes wrong with the client machine or application the memory data is lost. The data is stored locally in a dataset. Our solution is to frequently do a DataSet.WriteXML(FileName,XMLWriteMode.WriteSchema). This works very well in all situations except one so far. (If the applications crashes, the XML file is available on the local disk and we have routines to recover it and pick up where the user left off. (That's what we want). If the computer crashes, again, the XML file is there. But if the application and/or machine locks up (or appears to lock up) and the user performs an End Task on our application from the task manager, the XML file is not written. Note: To test, I can see the FileName.xml file exists after the first execution of writexml but the size is 0 bytes (Per Windows Explorer). It stays 0 bytes no mattter how large in memory it becomes. (Alt Tab to toggle between the app and Explorer -with refresh always shows 0 bytes). Even though Explorer says 0 bytes, if I then pull the plug on the PC, the XML file is actually saved to the local disk. But if I CTL+AlT-Del and say end task from the task manager, the XML file is Not saved to disk. (That confuses me). But in any event, I assume that if I could flush the streamwriter(?)/XMLTextWrite after each WriteXML the problem would be solved. Unfortunately, I can't figure out how to do so. I have tried to DIM as seprate XMLWriter but when I write to the same writer multiple times I then can't read it for recovery purposes becuase it appends the entire dataset each time instead of just the new data since the last write. I would greatly appreciate any help you can offer. I am not locked in to the XML soultion, it just works well considering the clients don't have an alternate database they can use and the current code is simplistic and runs relatively fast.

Even my data is also serialize and save it to XML file. Now as DataSet serialize, it's creating some extra information (schema information), And i don't need that. I only want to store the data in XML format. I don't want to store extra details like namespace etc... As it's increase XML file size. One thing is clear that this DataSet is a part of my object.

    - Display editable one-to-one data from n tables in one DataGrid... I'm surprised nobody else seems to have had this problem. I'm developing against a system in which stored procedures cannot be used and existing tables must be extended with one-to-one "extension" tables. Is it possible to bind a single DataGrid to two one-to-one related DataTables in such a way that all columns are editable and DataAdapters can be used to easily update the two tables afterwards? I can't use expression columns, because they're not editable. Do I have to go to the trouble of copying the data from the two tables into one common table and bind to that? That would be pretty messy, especially when it comes time to take the changes back to the original data tables for updating the database. I guess what I really need is for the "child" of the two tables (could be either table as they are related by their primary keys) to have proxy columns from the parent. Any advice on best practices welcomed. Nathan Tag: How to change the value of timeout in program Tag: 116314

    - "Procedure expects parameter" when calling SqlDataAdapter.Update() Hi, I have a SqlDataAdapter for which I have made the UpdateCommand manually. Both the Select and Update commands are custom stored procedures in SQL Server 2000. The Select part works fine; I can populate a dataset and modify it without problems. However, when I want to save the modifications in the database, and call myDataAdapter.Update(myDataSet), I get the following exception: Procedure 'MyUpdateProcedure' expects parameter '@Id', which was not supplied. MyUpdateProcedure actually takes several parameteres, of which the @Id parameter is the first. All parameters have corresponding columns in one of the DataTables (in myDataSet). All parameters (including @Id) are represented in the UpdateCommand.Parameters collection, and everything looks correct in the SqlDataAdapter.TableMappings collection (the correct table name is specified, and all parameters points to the corresponding dataset column). What else do I have to do? I'm so frustrated that I've actually considered looping through the modified rows and updating the database manually - something I of course want to avoid...

    - Problem with executing a DTS from a remote machine Hi all, We've created a VB.NET application which runs a couple of DTS packages on a SQL Server in a specific order using ADO.NET. When we runs this application on the same machine that SQL Server resides on it works fine. However when we run the application on another machine in the domain the first package is started but it doesn't finish. This package is a straightforward one: truncate a table, copy records (approx. 10.000.000) from one database table into the table which has just been truncated and finally create a couple of indexes. This step takes about 30 min. to complete. When we run it from a remote machine we can see that the table has been truncated however there are no records copied into it. When we look in the Proces Info in SQL Server the proces which is running the package has a status of: wait and as command: NETWORKIO. The wait time increases gradually. Does anybody know what the problem could be? TIA, Friso Wiskerke Tag: How to change the value of timeout in program Tag: 116311

    - "Timeout expired" for simple query Hi, I've made a HttpModule which deals with user authentication. On the first request in a users session, it fetches data from a SQL Server using the following code: using (SqlConnection connection = new SqlConnection(ConfigurationSettings.AppSettings["Database.Connection"])) { connection.Open(); SqlCommand sqlCommand = new SqlCommand("GetAdvisorEnterpriseLogin", connection); sqlCommand.CommandType = CommandType.StoredProcedure; sqlCommand.Parameters.Add("@InputUsername", HttpContext.Current.User.Identity.Name); SqlDataReader reader = sqlCommand.ExecuteReader(); reader.Read(); username = (string) reader["Username"]; password = (string) reader["Password"]; reader.Close(); } The "GetAdvisorEnterpriseLogin" procedure is a really simple one, and hardly takes 0.1 second to run. However, the first 1-3 times I access the page after a recompile (and once in a while otherwise), I get the following exception: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. I also get the exception after not using the system for a while, but I haven't experienced when the system is "in use", i.e. when the previous request was no more than a couple of minutes ago. Does anyone know what could cause this error, and how I can prevent it from happening? Regards, Nils Magnus Englund Tag: How to change the value of timeout in program Tag: 116308
