    - Oracle cursors not releasing with OracleClient Hi all, I'm having a problem with Oracle .net provider and Stored Procedures returning REF CURSOR vars. I'm using OracleClient v1.0.1012.0 with Framework 1.0 and when I fill a dataset with the stored procedure, the cursor is not released and I always end up with a ORA-01000 error (too much cursors opened). It's very frustrating and I've observed that if I change the OracleClient reference to the one from framework 1.1 it doesn't happen and the cursors are released when closing the connection. Unfortunately, I can't change the framework version I'm using so I'd like to know if there's something I could do to fix this behaviour with framework 1.0 Another strange thing I've noticed is that if I call the function (see code) in a pageload event of an aspnet application I don't get the ORA-01000 error but if I call it from the Console Application I can't. I'll put some code here to reproduce the behaviour, any help will be appreciated !! Thx in advance, ori using System; using System.Data.OracleClient; using System.Data; namespace ConsoleApplication2 { /// <summary> /// Summary description for Class1. /// </summary> class Class1 { [STAThread] static void Main(string[] args) { Class1 c = new Class1(); for (int i=0; i<850; i++) { c.try(); } } public void prova() { try { OracleConnection conn = new OracleConnection(@"<connection string here>"); conn.Open(); OracleCommand comm = new OracleCommand(); comm.Connection = conn; comm.CommandType = System.Data.CommandType.StoredProcedure; comm.CommandText = "PKG.READ"; comm.Parameters.Add(new OracleParameter("P_CURSOR", OracleType.Cursor, 38, ParameterDirection.Output, true, 38, 0, "", System.Data.DataRowVersion.Current, null)); OracleDataAdapter adapter = new OracleDataAdapter(comm); DataSet dset = new DataSet(); adapter.Fill(dset); conn.Close(); } catch (System.Exception ex) { //ORA-01000 Error when default 300 cursors are opened } } public Class1() { } } } Stored procedure CREATE OR REPLACE PACKAGE PKG AS TYPE etrcur IS REF CURSOR; PROCEDURE READ ( p_CURSOR OUT etrcur ); END PKG; / CREATE OR REPLACE PACKAGE BODY PKG AS PROCEDURE READ ( p_CURSOR OUT etrcur ) IS BEGIN OPEN p_cursor FOR SELECT <ANY SELECT HERE>; END SGM_READ; END PKG; / Tag: Udl File How to use it Tag: 72226

    - MySQL & WebForm - Please Help Hello, I just started to learn ASP.NET, and I am using MySQL for database, I have a question I hope someone can answer for me though :) I want to create a simple form that can edit and create a row in a database, for example the fields Name and Lastname. How do I go about this, can I somehow link my TextBox's to a field in the MySql database? So when I press Create-Button it adds the row with the fields from TextBox's itself? Or must I make a Button_Click event and make the SQL myself there? If I must do it myself, in PHP I used to create forms so all TextBox's were part of an array, then I could easilly make a foreach and create the SQL statement on the fly. This way I could add another TextBox to the page (and in the database ofcause), and not have to go change my code for it to be saved. Im looking for the best solution to creating/updating on a webform... and for my example a webform with 2 TextBox's (Name and Lastname) and 2 Buttons (Update and Create) would be good example, so I can use that method on bigger forms. I hope someone can point me in the right direction. Thanks, Cederstrom Tag: Udl File How to use it Tag: 72192

    - Accessing Excel thru Jet gives data in scientific notation Hi, I m trying to access an excel spreadsheet to load a named cells in a dataset. For this, I m using Jet OLEDB provider with ADO.Net. String cnString = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + fileName + "; Extended Properties=\"Excel 8.0;HDR=No;IMEX=1;\""; String sql = "select * from MyNamedCells"; Initially I was having problem with null values for certain cells where datatype appeared different to the provider. e.g. If a top cells of a column contain text data (say A13331123) and in the middle there was some numeric data (4509015284) .. the numeric data was being retrieved as null. This was fixed using IMEX switch. Now - althought the numeric data is being loaded, but it is coming in scientific notation (the above value converts to: 4.50902e+009). How can I get my text back with the right accuracy? Thanks. Tag: Udl File How to use it Tag: 72186

    - FoxPro, dBase III, and ADO.NET I have a newbie question about different database formats as they apply to ADO.NET. I need to get access to a .dbf file using ADO.NET. The files are in dBase III format. Does that mean I need to use the FoxPro Data Provider or that I only need to specify "Extended Properties=dBase III" in the connection string to connect to dBase III files? It's my understanding that FoxPro is just one of many programs that can read dBase III files (just like many text editors can read .txt files or html files). Is this the case? If so, why would someone be interested in using the FoxPro data provider? Thanks, Dave Tag: Udl File How to use it Tag: 72172

    - DataReader with a return parameter and an OUTPUT parameter. I have a stored procedure and I set up the command type to be StoredProcedure with the return value and the output parameter set to InputOutput. This StoredProcedure also returns a set of rows. From the best that I can tell if I use ExecuteReader() the first time it returns the OUTPUT parameter and it takes a second time to actually get the data. Is this the default behavior or is there some special setup to get this to return the data AND the OUTPUT parameter in one call to ExecuteReader()? Thank you for your suggestions.

    - formatting a label control with a date Probably a simple question: I have a combobox where the user will select a member number. I have two labels that are bound to the member's name (FirstName, LastName). I then have another label that is bound to the member's date of birth. Everything works fine in that when a member is selected from the combobox the name changes and the birthdate changes; however the label for the birthdate is in mm/dd/yyyy format but it also displays the time of 12:00 am. I want to delete the time. Is there a way to do this? Thanks for the information. Brad PS This is an oledb data adapter connecting to an access database. The date field in the database is formatted as short and the date-time picker in VB is a custom format of MMMM dd, yyyy. Tag: Udl File How to use it Tag: 72157

    - Inserting identity columns with CommandBuilder generated commands? Hi, I need to commit the changes to the database of a dataset containing many (MANY) datatables. A few of them have an auto-increment column, but I need to insert a specific value in the database (which is MS-SQL, by the way). My code is fine and I send a "SET IDENTITY_INSERT ON" to the database when needed. Since all the operations I need to perform are very basic and that I have many different tables, I am using the CommandBuilder object. The problem is that the Insert command does NOT include the auto-increment field. Is there a way to make the extra parameter is added to my InsertCommand? MSDN and the books I have were not of any help. Thank you very much! Carl PS: Here's the code... Public Sub CommitTable(ByVal table As DataTable, ByVal transaction As SqlTransaction, Optional ByVal allowIdentityInsert As Boolean = False) Dim da As New SqlDataAdapter("SELECT * FROM " + table.TableName, transaction.Connection) da.SelectCommand.Transaction = transaction Dim cmdBuilder As New SqlCommandBuilder(da) Dim cmd As SqlCommand cmdBuilder.QuotePrefix = "[" cmdBuilder.QuoteSuffix = "]" da.InsertCommand = cmdBuilder.GetInsertCommand da.UpdateCommand = cmdBuilder.GetUpdateCommand da.DeleteCommand = cmdBuilder.GetDeleteCommand cmd = New SqlCommand("DELETE FROM " + table.TableName, transaction.Connection, transaction) cmd.ExecuteNonQuery() If allowIdentityInsert Then cmd.CommandText = "SET IDENTITY_INSERT " + table.TableName + " ON" cmd.ExecuteNonQuery() End If da.Update(table) table.AcceptChanges() If allowIdentityInsert Then cmd.CommandText = "SET IDENTITY_INSERT " + table.TableName + " OFF" cmd.ExecuteNonQuery() End If End Sub Tag: Udl File How to use it Tag: 72149

    - Using Oracle Packages in Visual Studio.NET 2003 designer Hi Group, we've noticed that Visual Studio.NET 2003 does not seem to be capable of reading the parameter data for commands on oracle stored procedures that are collected in packages. We can create a command, change the command type to StoredProcedure and enter a stored procedure or function name and it works fine (same functionality as simply drag'n'dropping the stored procedure or function from the server explorer to the designer). That works smoothly. However, when we enter a function name from a package, the name cannot be resolved. It works fine during runtime, when we have manually added the parameters (so there is no spelling problem with the names) - but the designer simply doesn't find the stored procedure or function. Is this a known problem? Are there any workarounds? What we're considering is creating temporary stored procedures (not in a package) to automatically get the parameters, and then manually changing the name so that it referes to the original function stored in a package. This is still easier than manually entering the parameters - but still it's rather cumbersome and time consuming... regards, david -- Auch das geht vorüber.

    - unclosed connections problem We have recently migrated a classic asp/sql server web site from windows server 2000 without the .net framework installed to windows server 2003. We seem to be finding that sql server is using up excessive amounts of RAM, much more than the old machine, even with the same amount of traffic. I suspect there may be a number of unclosed database connections in the legacy asp code and that windows 2003 is not shutting them down as quickly as with windows 2000. Does this sound plausible and if so is their any temporary work around to solve the problem. (It may take some time to correct all the code problems) Scott Tag: Udl File How to use it Tag: 72140

    - OUT NUMBER Parameters with Microsoft OLE DB Provider for Oracle => Hi Group, we're experiencing a very weird problem with the Microsoft OLE DB Provider for Oracle. We're using the version shipped with Visual Studio.NEt 2003. When we have any OUT parameter of type NUMBER, we get OCI-22060 (Argument [2] ist eine ungültige oder nicht initialisierte Zahl). This also happens when calling a function, where RETURN_VALUE is declared as NUMBER. OUT parameters as VARCHAR2 work fine, whenever we switch to NUMBER, the problem occurs. We're simply drag'n'dropping the command (stored procedure) from the server explorer. Could it be we're doing anything wrong? Or is this a bug in the provider? If so, are there any workaround or fixes available? regards, david -- Auch das geht vorüber.

    - SqlDataAdapter and finalization Hello all, I had some code that forgot (or should I say I forgot) to call Dispose on a SqlDataAdapter, so I thought it will be okay since SqlDataAdapter inherits via Component so the inherited Dispose/Finalize pattern would be picked up. However, after poking around with a decompiler I notice that within the constructor of SqlDataAdapter the call to GC.SuppressFinalize() is made so because my code forgot to call Dispose, the cleanup code will never be called via the overriden Finalizer in Component. Does anyone haveany thoughts on the rationale behind the SqlDataAdpater choosing to call GC.SuppressFinalize() in its constructor. Colin Tag: Udl File How to use it Tag: 72084

    - newbie, converting from ado to ado.net --> datareader help needed. Hi, I am converted an existing vb6 web app to vb.net and have run into a bit of a problem with data access via ADO.NET. I am doing a full text search against a SQL Server 2000 DB, the SP that I call to do this returns multiple resultsets, therefore from the documentation I found that I would have to use the SqlDataReader in order to move from one resultset to another. However here lies the problem. After the SP is called in the vb6 version I used the recordsets "RecordCount" method to create a large enough array to do some additional processing (don't ask). But I can no longer do this with the datareader because you read one row at a time. So my problem is how do I find out how many records are in the current resultset when using a datareader? As you can imagine the search SP is not trivial and repeating the query twice just so I can find out the recordcounts is not acceptable. My first guess at a solution would be to use an ArrayList and then just call it's .Add method then I wouldn't need to worry about array size. Any other suggestions welcome.

Pardon my french, but WHAT THE HELL DO I NEED TO DO TO GET THIS STUPID THING WORKING? Can somebody provide a code sample???? Thanks Tag: Udl File How to use it Tag: 72069

    - object model - dataset, dataadapter, datatable Hello All, Could you guys help me understand the ado.net object model ? This is what I think, correct me if I am wrong * DatAdapater acts as a bridge to bring in/send out data to database * Dataset is in-memory cache, disconnected from db, doesnt talk to db directly * DataTable could be a part of dataset. could multiple table from a common datasource be a part of same dataset ? * How to add multiple tables to same dataset, using same datasource ? * A separate dataadapter is needed, for each SELECT/Stored proc, which will bring in data to dataset Can a single dataadapter be used for multiple tables added to the same dataset having common source ? I am somehow confused & thinking that there has to be 1 dataadapater for each SELECT querying diff tables Regards Kalpesh Tag: Udl File How to use it Tag: 72067

    - Handling exception inside SQL Server stored procedure & return custmised message Hi friends, I am observing a pretty strange behavior when i try executing stored procedure using C# code. This is explained below: I have a table in which I have some constraints defined like unique, foreign key, check, etc. I have created a stored procedure to insert a record in this table. In this procedure, i am doing explicit exception handling. Say if there is any constraint getting violated during insert operation then I am catching the @@Error value in my locally declared variable @ErrorCode and if it's not equal to zero, then I am returning a customised error message via a output parameter declared in the procedure body, plus I am returning the actual database error code to the calling program by direct return @ErrorCode statement. Now when I execute this procedure with some dummy test values using a SQL Query Analyzer, it gives me perfect result. Now when I try to execute the same procedure from C#- ADO.NET code, with fresh values (which is not violating any constraints), it gives me perfect result. But the moment I test it with any values which violates the database constraint, exception message is displayed directly on the screen. As such, as per the logic implemented in stored procedure, the constraint violation message shouldn't be thrown by the C# code directly on the screen. I am just surprised to see this strange behavior. I am sure you have a reason for this strange behavior, plus an alternative way to do the same. Thanks and Regards, Amit Tag: Udl File How to use it Tag: 72066

    - stored procedure and crystal reports for VS .Net I'm trying to get the results from a stored procedure into a crystal report in VS .Net. The stored procedure has one input parameter (date). When ever I create a new crystal report and set the database datasource to the stored procedure and then try to add a chart, it gives me an error about 'Convert' native error: 156. This error I guess has to do with maybe the Date input parameter not being specified? I'm not sure. Is there any real step by step examples of how to create a crystal report in VS .Net from a stored procedure data source? On a another note, is it possible to execute and get the results of a stored procedure (that has one input parameter) and put it into a dataset? If so how? Everything that I've ever read doesn't make mention of doing this. Thanks in advance!!!!!! Tag: Udl File How to use it Tag: 72056

    - .net framework object code store Hi, our team is in the process of setting up a .net development environment. We have begun creating common code for reuse in DLL's and we want to allow our developers to share this code from a central server. We have a .Net Framework server where these DLL's can be installed but the question is, how can developers reference the code from their client workstations? Tag: Udl File How to use it Tag: 72055

    - PLEASE READ CAREFULLY MAKE MONEY FAST AND EASY HURRY!!!! Make Money Fast A little while back, I was browsing these newsgroups, just like you are now, and came across an article similar to this that said you could make thousands of dollars within weeks with only an initial investment of $6.00! So I thought," Yeah, right, this must be a scam", but like most of us, but I was curious, so I kept reading. Anyway, it said that you send $1.00 to each of the 6 names and address stated in the article. You then place your own name and address in the bottom of the list at #6, and post the article in at least 200 newsgroups. (There are thousands) No catch, that was it. The main difference between this system and others is that you have a mailing list of 6 instead of 5... This means that your average gain will be app. 15 times higher!!! So after thinking it over, and talking to a few people first, I thought about trying it. I figured what have I got to lose except 6 stamps and $6.00, right? Like most of us I was a little skeptical and a little worried about the legal aspects of it all. So I checked it out with the U.S. Post Office (1-800-725-2161) and they confirmed that it is indeed legal! Then I invested the measly $6.00.............plus postage Well GUESS WHAT!!... Within 7 days, I started getting money in the mail! I was shocked! I still figured it would end soon, and didn't give it another thought. But the money just kept coming in. In my first week, I made about $20.00 to $30.00 dollars. By the end of the second week I had made a total of over $1,000.00!!!!!! In the third week I had over $10,000.00 and it's still growing. This is now my fourth week and I have made a total of just over $42,000.00 and it's still coming in rapidly....... It's certainly worth $6.00, and 6 stamps, I spent more than that on the lottery!! Let me tell you how this works and most importantly, why it works.... also, make sure you print a copy of this article NOW, so you can get the information off of it as you need it. The process is very simple and consists of 3 easy steps STEP 1 Get 6 separate pieces of paper and write the following on each piece of paper "PLEASE PUT ME ON YOUR MAILING LIST." Now get 6 US$1.00 bills (or equivalent in your local currency) and place ONE inside EACH of the 6 pieces of paper so the bill will not be seen through the envelope to prevent thievery. Next, place one paper in each of the 6 envelopes and seal them. You should now have 6 sealed envelopes, each with a piece of paper stating the above phrase, your name and address, and a $1.00 bill. What you are doing is creating a service by this. THIS IS ABSOLUTELY LEGAL! Mail the 6 envelopes to the following Addresses: #1) J Alex Biley 69 Manningham St. Parkville, Vic 3052; Australi #2) Suranga Sampath 237/a Bell St. Coburg, Vic 3058; Australi #3) Greg Davidson 1370 South Madison Ave. Clearwater, Fl 3375 #4) J. Schlundt 190 Brookline St. Newton Ma 0245 #5) D. Hale Jr. 407 Edgewood Ave. Pittsburgh, Pa 1521 #6) Nimai Jaekley; 3311 Landon Dr. West Unit A; Bullhead City, A 8642 STEP 2 Now take the #1 name off the list that you see above, move the other names up (6 becomes 5, 5 becomes 4, etc...) and add YOUR Name as number 6 on the list. (Use your 'delete" key to remove name #1 and move all other names up. Then change numbers and add your name as #6) STEP 3 Change anything you need to, but try to keep this article as close to original as possible. Now, post your amended article to at least 200 newsgroups. (I think there is close to 24,000 groups) All you need is 200, but remember, the more you post, the more money you make! Don't know HOW to post in the newsgroups? Well do exactly the following: THAT'S IT! All you have to do is jump to different newsgroups and post away, after you get the hang of it, it will take about 30 seconds for each newsgroup! **REMEMBER, THE MORE NEWSGROUPS YOU POST IN, THE MORE MONEY YOU WILL MAKE!! BUT YOU HAVE TO POST A MINIMUM OF 200** That's it! You will begin receiving money from around the world within days! You may eventually want to rent a P.O. Box due to the large amount of mail you receive. If you wish to stay anonymous, you can invent a name to use, as long as the postman will deliver it. **JUST MAKE SURE ALL THE ADDRESSES ARE CORRECT** Now the WHY part: Out of 200 postings, say I receive only 5 replies (a very low example). So then I made $5.00 with my name at #6 on the letter. Now, each of the 5 persons who just sent me $1.00 make the MINIMUM 200 postings, each with my name at #5 and only 5 persons respond to each of the original 5,that is another $25.00 for me, now those 25 each make 200 MINIMUM posts with my name at #4 and only 5 replies each, I will bring in an additional $125.00! Now, those 125 persons turn around and post the MINIMUM 200 with my name at #3 and only receive 5 replies each, I will make an additional $626.00! OK, now here is the fun part, each of those 625 persons post a MINIMUM 200 letters with my name at #2 and they each only receive 5 replies, that just made me $3,125.00!!! Those 3,125 persons will all deliver this message to 200 newsgroups with my name at #1 and if still 5 persons per 200 newsgroups react I will receive $15,625.00! With an original investment of only $6.00! AMAZING! And as I said 5 responses is actually VERY LOW! Average is probable 20 to 30! So lets put those figures at just 15 responses per person. Here is what you will make: at #6 $15.00 at #5 $225.00 at #4 $3,375.00 at #3 $50,625.00 at #2 $759,375.00 at #1 $11,390,625.00 When your name is no longer on the list, you just take the latest posting in the newsgroups, and send out another $6.00 to names on the list, putting your name at number 6 again. And start posting again. The thing to remember is, do you realize that thousands of people all over the world are joining the internet and reading these articles everyday, JUST LIKE YOU are now!! So can you afford $6.00 and see if it really works?? I think so... People have said, "what if the plan is played out and no one sends you the money? So what! What are the chances of that happening when there are tons of new honest users and new honest people who are joining the internet and newsgroups everyday and are willing to give it a try? Estimates are at 20,000 to 50,000 new users, everyday, with thousands of those joining the actual internet. Remember, play FAIRLY and HONESTLY and this will work. You just have to be honest. Make sure you print this article out RIGHT NOW, also. Try to keep a list of everyone that sends you money and always keep an eye on the newsgroups to make sure everyone is playing fairly. Remember, HONESTY IS THE BEST POLICY. You don't need to cheat the basic idea to make the money!! GOOD LUCK to all and please play fairly and reap the huge rewards from this, which is tons of extra CASH. TRUST ME IT DOES WORK! I am sure this will work out, try it and see.

    - calling a dataAdapter Update in DataTable.DataRowChanged Event At some part of my application I want to hide the idea of a cache (dataset) from my user, so went the user deletes a row using the data bound UI, which deletes the row from the corresponding data table, I want to make a call to commit the changes to database as well, so what I did is I registered an event handle for the DataRowChanged Event and tried to call DataSet.GetChanges. The problem is DataSet.GetChanges return null. Is is because the DataSet is still in edit mode when the DataRowChange event fires? So how can I commit data at the same time as it is deleted from the dataset apart from putting a separate 'commit' button? thx in adavance Tag: Udl File How to use it Tag: 72030

    - Behind the scenes -- how is a DataTable implemented? When one gets a row from a database (ie, a DataTable), the row contains a typed value in each column. How is this typically implemented behind scenes. I want to build this functionality myself. The reason I want to do this is because I need an in-memory table without any of the overhead of a DataSet or DataTable. Thanks! Tag: Udl File How to use it Tag: 72027

    - Stop deleting a Row in the Changing event within a DataGrid Hi! I wan't to prevent a user to delete some Rows showed in a DataGrid. I registered for the DataTable.RowDeleting event and tried to throw an exception when deleting occours but is forbidden(as proposed in the msdn). Problem: Nobody catches the error, so an application Exception gets shown to the user. How can I catch the exception or prevent deleting a row in an other way?

Hi Stan,

Try this:
oleDbConnection1.ConnectionString = "File Name=test.udl";

BTW, it is better to provide connection string by yourself because of
security (udl stores password in clear text) and beacuse it is faster.
