    - excel formulas and visual c# .net Hi, I developed an application in visual c# .net This application reades an excel file and displays its contents into a dataGrid (OleDbDataAdapter). What I discovered is that if a cell in excel has a constant, then i can retrieve its contents. Also, if a cell has a formula (e.g. =K10) and K10 has a constant then it is also fine. But if the cell's properties are of Custom type, with type, say hh:mm, then i cannot get the contents to the dataGrid. Do you know why this is happening? Has anyone found a workaround for it? Thanks in advance Kostas -------------------------------- From: Kostas Alifantis ----------------------- Posted by a user from .NET 247 (http://www.dotnet247.com/) <Id>ICkne+DCCUWlYeHpuluf+w==</Id> Tag: Failed to connect DB Tag: 106778

    - max pool size reached on dev workstation In the course of debugging applications on my development workstation (ASP.NET 1.1.4322, SQL Server 2000, ADO.NET) the app will sometimes be unable to establish a database connection when I choose Debug->Start. (When stopped during debugging, the code does not always reach the Finally {} block where the connections typically get closed.) I get a timeout error indicating that max pool size may have been reached. Stopping and restarting SQL Server does not clear this problem, and so I have been rebooting. Is there another service that maintains the connection pool, which can be bounced to free the stuck connections? Thanks Timo Tag: Failed to connect DB Tag: 106774

    - Commit/Rollback Transaction generates an error. I have table Employee - Code varchar(5) Name varchar(100) Age int Using Ado.Net 1) Create a SQLConnection Object and open the connection. 2) Create a SQLCommand object using that connection. 3) Create a Transaction using SQLConnection.BeginTransaction(System.Data.IsolationLevel.ReadCommitted) 4) Attach the Transaction to the SQLCommand (ie. SQLCommand.Transaction= TransactionObject) 5) Execute an insert statement on the Employee Table using SQLCommand.ExecuteNonQuery() (ie. SQLCommand.CommandText = "Insert into Employee(Code, Name, Age) Values('ABC', 'ABCDEFG', '213')" SQLCommand.ExecuteNonQuery() ) 6) Call another function (eg: test()), which again inserts a record in the same table. This function would raise an sql exception, but we would ignore it in the function. (ie. Private Sub Test(ByRef oCmd As SqlCommand) Try oCmd.CommandText = "Insert into Employee(Code, Name, Age) Values('XYZ', 'XYZDEFG', '213a')" 'This would raise an error since Age is of Type Int oCmd.ExecuteNonQuery() Catch ex As Exception 'Ignore the error and return MsgBox(ex.Message) End Try End Sub ) 7) Issue Commit Statement (ie.

    - DataView rows - filtered hello, so the DataView object is confusing me. i have a dataset of a bunch of rows, some of white my page needs to filter out before binding. no problem, i make a new dataview, set a filter and then bind the dv to my page. ala: DataView myDV = New DataView(myDS.Tables[0], "Show=1", "ID DESC", DataViewRowState.CurrentRows); myRepeater.DataSource = myDV; ...this is cool and it only shows what its supposed to. however, what confuses me is... when i try to get the first row of my filtered view, i do this: someLabel.Text = myDV.Table.Rows[0][0]; ...i am getting a row that was filtered out! (the first row happens to be one i dont want to show). i had thought the DataView was a new collection of criteria-matching rows. whaaa? guess not. so i have two questions: 1) how does a DataList/Grid/whatever know to exclude binding filtered out items 2) how can i call up a single item from *only* the list of criteria-matching rows? thanks! matt Tag: Failed to connect DB Tag: 106735

    - DataGrid paint exception when size too small I have a .NET windows forms application with one form displaying data. I have a tree view on the left side and the datagrid on the right side. Tree view allows the user to select verious items and based on that selection the datagrid is bound to the appropriate datasource and table from the database. This works well. The problem comes when I resize my form and the grid portion is not visible or just barely visible. Now when I perform the same operations by selecting various items in the tree I get an exception System.ArgumentException with Message : '0' is not a valid value for 'value'. 'value' should be between 'minimum' and 'maximum'. Source : System.Windows.Forms. This happens when I call SetDataBinding method. When I again resize the form so that the grid is more visible this problem goes away. I have also seen a bizzare display with red cross over the entire grid area when I resize the grid again. Is this a known issue in the datagrid ? Can somebody help me ? Thanks Tag: Failed to connect DB Tag: 106701

    - Parameter ?_1 has no default value I'm using the HierCube .net OLAP component from rainbowsoft (http://www.rbwsoft.com/) in a vb winform application (vs2003).

At runtime the app provides values for the params like so: oledaPivotData.SelectCommand.Parameters("Conversion").Value = cboConversion.SelectedValue oledaPivotData.SelectCommand.Parameters("Year").Value = cboYear.SelectedValue The cube works fine. However the cube control won't let me access the Dimension Mapping facility, it complains that "Parameter ?_1 has no default value". I'm not sure how to solve this. I've written to the control developers, but they can be slow to respond...and this issue seems to be more generic than specific to this control.

    - MSSQL - ON DELETE SET NULL Hello NG, Does SQL Server support "ON DELETE SET NULL"? I have a couple of CREATE TABLE / ALTER TABLE commands that are all in one string, separated by ";\r\n", and send them to SQL Server (without transaction context). The SQL itself is created dynamically, but here is a sample (for simplicity, I scrapped irrelevant stuff). I always get an SqlException with as many SqlErrors in it as there are ON DELETE SET NULL occurances. The same thing works with Access, though (with Jet-SQL syntax of course). Or (being a consumer product) is Jet just "fault tolerant" and ignores that? CREATE TABLE TFoo ( ID UNIQUEIDENTIFIER NOT NULL PRIMARY KEY, Bar UNIQUEIDENTIFIER); CREATE TABLE TList ( ID UNIQUEIDENTIFIER NOT NULL PRIMARY KEY ); CREATE TABLE TBar ( ID UNIQUEIDENTIFIER NOT NULL PRIMARY KEY, Foo UNIQUEIDENTIFIER, List UNIQUEIDENTIFIER, FOREIGN KEY (Foo) REFERENCES TFoo(ID) ON DELETE SET NULL, FOREIGN KEY (List) REFERENCES TList(ID) ON DELETE SET NULL); ALTER TABLE TFoo ADD FOREIGN KEY (Bar) REFERENCES TBar(ID) ON DELETE SET NULL; Many thanks, Phil Tag: Failed to connect DB Tag: 106667

    - Master-Detail records I wrote an application in .NET 2003, everything worked fine for several weeks. This application has several text boxes and a detail grid. I put navigation buttons on the form to move to the next record, which will also change the data in the grid. I didn't make any changes to the application, but all of a sudden, the detail grid quit updating with changes to the position of the master. If I just did it wrong in the first place and it should have never worked, then that's the way it is, but I would like to know what I did wrong, and maybe some ideas of why it would all of a sudden decide to stop working.

    - Combining multiple datatables on a unique ID Hi, Using VB .NET I want to combine app 100 different ADO.NET datatables, each with app 50,000 records which have been populated from SQL. They share a common ID, and I would like to group by this ID and sum up the other 4 columns to give me one master table. I understand how to populate the datatables but don't know what the best/fastest way to query across different datatables is. Any advice on querying one datatable with another on a common ID is much appreciated. Tag: Failed to connect DB Tag: 106630

    - Data Adapter Problem? The following is an issue using ado.net in an asp.net page using SQL Server.... I have a Statement that when executed from my asp.net dataadapter takes about 24,000 reads according to SQL Profiler. I think the read count is accurate as it grids a long time. The same statement when executed from Query analyzer takes only 116 reads and it executes quickly. Why the Difference? Same table, same server. The statement as it executes is as follows: exec sp_executesql N'SELECT Amount, InvoiceNum, Job FROM Unpaid_Bal WHERE (InvoiceNum = @InvoiceNum) AND (Job = @JobNum)', N'@InvoiceNum varchar(50),@JobNum varchar(11)', @InvoiceNum = '100488RS', @JobNum = 'ABCE-036245' thanks, G Tag: Failed to connect DB Tag: 106613

    - Trying to use Nile Oracle DAAB in VB I am trying to use the Oracle DAAB found in the Nile application at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/manprooracperf.asp.

    - Wierd Occurrance I have an intermittant problem that occurs a couple of times a week in a handful of places in the code (the same places at different times). The error is 'Object reference not set to an instance of an object'. After much research (it's not my code), I've found that it is occuring when a datareader is being used after being returned from a another method that queries an Oracle database. Here is the method: Public Function GetDataReader(ByVal strSelect As String) As OleDbDataReader Dim rc As Integer Const FUNCTION_NAME As String = CLASS_NAME + ":SelectSQL" Try objConn = New OleDbConnection(strConnectionString) objCmd = New OleDbCommand(strSelect, objConn) objCmd.Connection.Open() GetDataReader = objCmd.ExecuteReader(CommandBehavior.CloseConnection) Catch ex As OleDbException If oLogFile Is Nothing Then oLogFile = New clsLogFile() rc = oLogFile.LogErrorMessage(FUNCTION_NAME, ex.ErrorCode, ex.Message + " SQL Statement: |" + strSelect + "|") GetDataReader = Nothing Finally objConn = Nothing objCmd = Nothing End Try End Function As I mentioned above, the error is occurring the first time the returned datareader is used in the calling code. The first thing the calling code does is check to see if the returned datareader is closed. When this statement executes the datareader object does not exist. Here is an example of the calling code: oDatabase = New ICPT.clsDatabase(oSession.ApplicationConnectionString, oSession.DatabaseType) strSQL = "SELECT * FROM TransactionCodes" rdrTranCode = oDatabase.GetDataReader(strSQL) 'verify the datareader is open and contains a record If rdrTranCode.IsClosed = False Then '' bomb on this line 'do something End If I've checked the application log files and there is no indication that the GetDataReader() method is trapping and logging an error. Any of you guys see a problem with this code? It looks as if a database connection and subsequent query are being done successfully (nothing in error logs), but when the datareader is returned the reference to the datareader is lost. I can tell you that most of the things this application does involve at least a few calls to GetDataReader(), and sometimes there are quite a few calls to perform a certain function. I've checked the Oracle log and trace files and there is no indication of anything flaky. Any ideas? Thanks, Todd Tag: Failed to connect DB Tag: 106607

    - Performance Problems with filtering in Dataview Hi all! I would really appreciate getting some help on the following problem: I use a cached dataview as a source for my datagrid. The user selects items from controls and based on the selections a filter is applied on the dataview and the datagrid re-databinded. Now the problem: when I test the application on the server it works extremely fast, the filtering processes within 2 to 3 seconds on a datatable with 4000 rows! When I try to access the same site on the server from a client-Computer in the business network the filtering takes about 40 to 60 seconds!!! Does anyone have a clue how to explain these extreme performance differences?

    - SPs, sqlCommand and Terminal Services Hi all, I just ran into something very, very strange.. I have this application which fires of a series of SQL Scripts using the sqlCommand Object. One of the statements executes the procedure "sp_addMergePublication" on the server. If I do this on a local machine, everything works fine. But if I run my application on a server using Terminal Services then the application will Halt on that statement saying that "A severe error has occured." and that any changes should be discharged. Note. This happens ONLY when I run the application remote and it is not an error bound to a specific machine. I can recreate the problem on any given server.

    - Losing records in a transaction I'm currently using .NET 1.0 and MS .NET provider for Oracle to connect to my Oracle9i R2(9.2.0.5) database. I have a piece of code which in essence is as given below Try m_Conn = New OracleConnection(strDBConnString) m_Conn.Open() m_Trans = m_Conn.BeginTransaction() 'Here I have a series of inserts and updates on huge tables. I am using ExecuteNonQuery function of the OracleCommand object for all these operations. InsertTb1() InsertTb2() UpdateTb3() 'If all goes fine I commit the whole transaction m_Trans.Commit() Catch ex as Exception 'Here I catch all exceptions and rollback the whole transaction m_Trans.Rollback() Finally m_Conn.Close() End Try I have similar code doing different actions on the same tables, running through out the application. Off late I have been getting database locks and subsequent slowness in the application. My DBA tracks down the holding statements and kills the session. Now, if the script used in InsertTb1() happens to be the statement of the assocated session that was killed, I expect Oracle to throw an exception, which inturn should be caught in the catch block and the whole transaction shoud be rolled back. But, it looks like I do not get an exception, due to which the code proceeds to fire the subsequent statements (InsertTb2(), UpdateTb3()) and I end up with incomplete records in the database. I have had an instance before, where Oracle database was throwing a 'No Data found' exception, but the exception never bubbled to my code i.e. The .NET provider ignored the excepton. Could this be a similar case? -- Message posted via http://www.dotnetmonster.com Tag: Failed to connect DB Tag: 106591
