    - DataColumn.Add bug? DataType parameter cannot be added I am trying to create a DataColumn with Name and DataType parameters. As I understand from the documentation, one of the overloads supports creation of a column with these two parameters. When I tried folllowing, however I get error saying 'int' denotes a 'class' where a 'variable' was expected code ------- DataColumn dc = new DataColumn("Name", System.Int32) or DataColumn dc = new DataColumn("Name", System.Type.GetType(System.Int32)) or MyTable.Columns.Add("Name", System.Int32) ERROR: ------- 'int' denotes a 'class' where a 'variable' was expected I am using .NET Framework 1.1 in Visual Studio.NET environment. Is this a bug or am I doing something wrong Tag: rergarding assembly load error Tag: 79000

    - Problem with a DataAdapter - Newbie Question Hi In the following code, I get an Error when I try to Fill the Dataset String sql = "SELECT * FROM Table1 UNION SELECT * FROM Table2 UNION SELECT * FROM Table3" SqlDataAdapter earnAggAdapter = new SqlDataAdapter(sql, con) earnAggAdapter.Fill(tempDS, "Earnings"); // I get a "System Error" her If I try with only the Union of Table1 and Table2 it works Does that mean that the DataAdapter does not support more than one Union in the same statement Is there another way to make this work thanks Jane Tag: rergarding assembly load error Tag: 78998

    - SqlDataReader advancing on each line of executable code within a loop I have the following code (this is only a small snippet of the code) compiled into a VB.Net exe file. The SqlDataReader (myReader) is populated via an SqlCommand.ExecuteReader() method call where the CommandType is a stored procedure on SQLServer2000. 1: myReader = myCommand.ExecuteReader() 2: Do While myReader.Read() 3: Select Case myReader.GetInt32(0) 4: Case 1 5: ' do one thing 6: Case 2 7: ' do something else 8: Case 3 9: ' do yet another thing 10: End Select 11: ' more processing of the first record Loop According to the SqlDataReader documentation it is supposed to advance through the records on each call of the Read method and it is supposed to be positioned just prior to the first record right after the ExecuteReader method fills it. The issue I am experincing is that the reader is positioned on the first record after the ExecuteReader method (line 1). Consequently, after the Raed method is called on line 2, the value of the Select Case expression is now that of the second record. Also, after each Case evaluation (lines 4,6, and 8) the reader is advancing. Therefore, by the time it loops back to the Read method (Line 2) it is impossible to determine where the reader will be positioned. Line 1 executes: reader positioned on record 1 Line 2 executes: reader positioned on record 2 Line 3 executes: reader positioned on record 3 Line 4 executes: reader positioned on record 4 Line 6 executes: reader positioned on record 5 Line 8 executes: reader positioned on record 6 Line 9 executes: reader positioned on record 7 Line 11 through N executes: the reader advances for each executable line of code. Given that this is an exe file, there is no web.config file, so I'm wondering if there is some other location that a particular setting may be causing this behavior. I know I could put the initial data from the stored procedure int a DataSet and then iterate through the Rows collection, but I'd rather keep it simple with the Reader.Read methodology. Any help or insight into the cause of the observed behavior will be appreciated. Thanks, Tim Tag: rergarding assembly load error Tag: 78994

    - Connections Not Closing I am using the data access application block running on Windows server 2003 and accessing SQL 2000 database (on the same box). I have some very simple code that is getting executed from a asp.net page. The code is calling executeNonQuery in a loop 30 times. I notice that after the code executes and I go into SQL Enterprise Manager and look at the open connections there are 30 open connections. Is there something I am missing ? I thought the application block would handle closing the connections. The other interesting thing is if I run the same code on Windows 2000 server accessing the database on the 2003 server everything works ok. Any ideas ???

    - Sysntax Error Inserting into a table with an OleDbCommand Hi all, I need another set of eyes to look at a problem I'm having. I'm trying to insert data into a Micrsoft Access 2002 table using the following SQL statement (all fields are Text): "Insert Into Customers (UserName, Password, FirstName, LastName, Address, PostCode, PhoneDay, PhoneEve, PhoneMob) Values ('Jack', 'beanstalk', 'Jack', 'Beanstalk', 'Nowhere', 'Nothing', '00000000', ' ', ' ')" As far as I can tell, there is absolutely nothing wrong with this Insert statement but ADO.Net thinks different and I keep getting a "Syntax error in INSERT INTO statement" error. The code I'm using is as follows: bool AllOk = true; RowsAffected = 0; try { OleDbConnection cn = new OleDbConnection(cnString()); cn.Open(); OleDbCommand cmd = new OleDbCommand(SQLstmt, cn); RowsAffected = cmd.ExecuteNonQuery(); <----THIS DOESN'T WORK cn.Close(); cn.Dispose(); cn = null; cmd.Dispose(); cmd = null; } catch (Exception e) {AllOk = false;} I'm getting desperate, can anyone tell me what I'm doing wrong.

    - Microsoft Dotnet, Timestamp, and Char <very odd> Hi there, I am calling a number of Oracle stored procedures via the Microsoft OracleClient and the ODP.Net client (Using OracleDataAdapter.Update and/or Direct OracleCommand.ExecuteNonQuery in both) and I am noticing that any char parameters are over-padded with a full set (eg. 5 for char(5)) of blank characters (even when no padding is necessary or in addition to correct padding) whenever they are located after a timestamp parameter. This, of course, causes an 'Inserted value too large' error on those overpadded columns. The timestamp parameter has a null default, and causes no problems if the parameter is not passed and the default applied. However, if the parameter is passed with a actual value or DBNull.Value then the error occurs. Has anyone experienced anything like this? We are faced with making sure timestamp parameters are always at the bottom of the parameter list or using varchars for all logically fixed string columns. Neither really addresses the root problem.

    - Query string issue with Microsoft access. Hello Everyone, I am having an unusual problem. I have this string that I am using as the Select Command for an Access database: SELECT time.employee, time.timein, time.timeout, time.ichkalt, time.ochkalt, time.realin, time.realout, employees.FName, time.iDate, time.oDate, FROM departments INNER JOIN (employees INNER JOIN [time] ON employees.employeeid=time.employee) ON departments.departmentid=employees.departmentid WHERE ((time.oDate) <= " & o & " ) And ((employees.employeeid)= " & eid & " ) AND ((time.iDate)>= " & i & " ) The i, o, and eid variables have been declared already. The result set works when you remove the 'oDate <=" & o & " )' part of the statement. When you run the query without that criteria, the result set is returned correctly. When you add that criteria to the string, no results are returned, even when I am inserting correct information. Does anyone have a clue as to what to do? Thanks in advance.

    - Confused about DataRowVersion.Default From MSDN on DataRowVersion.Default: "The row the default version for the current DataRowState. For a DataRowState value of Added, Modified or Current, the default version is Current. For a DataRowState of Deleted, the version is Original. For a DataRowState value of Detached, the version is Proposed." Reading the above, I would assume that this code: ///// ReturnValue = MyDataRow[ "MyFieldName", DataRowVersion.Default ]; ///// Should be equivalent to this code: ///// if ( MyDataRow.RowState == DataRowState.Deleted ) { ReturnValue = MyDataRow[ "MyFieldName", DataRowVersion.Original ]; } else { ReturnValue = MyDataRow[ "MyFieldName", DataRowVersion.Current ]; } ///// However, the first block of code throws DeletedRowInaccessibleException while the second one works just fine. Am I reading the documentation wrong? What am I missing? Thanks, -Steve Tag: rergarding assembly load error Tag: 78981

    - Problem with SQL Server I have an asp.net form that works fine with an Access database. Now I want to use Sql Server 2000. It is installed on the same Windows 2003 machine as the aspx code runs. I cannot seem to have a SqlConnection successfully connect. I use the following: string str = "Persist Security Info=False;Integrated Security=SSPI;database="+strDatabase+";server="+strServer+";Connect Timeout=30"; m_SqlConnection = new SqlConnection(str); m_SqlConnection.Open(); I get Login failed for user 'NT AUTHORITY\NETWORK SERVICE' I have also tried to leave out the Persist Security Info and Integrated Security, and replace it with uid=sa;pwd=<my sa password here> but I get the error: Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection. The same thing occurs for any user that I add to the Enterprise Manager. At this point I am not sure what I need to do to configure Sql Server. I know that there are many knowledgable Sql Server users out there. Can anyone answer my question?

    - Strange ADO.NET/Sybase/Sybase OLEDB problem We've recently run in to a very strange problem with a windows service that we have developed in VB.NET and that accesses a Sybase database using the Sybase OLEDB driver via ADO.NET. Every morning about 5am, the windows service checks a specified directory, looking for data export files. If it finds them then it parses them, uploads the contents to a set of temporary tables and then runs a stored procedure (call it MergeData) to merge the needed data from the temporary tables in to the tables used by our main system. It then fires off another couple of stored procedures to prepare report data and then a set of reports are generated. This has all worked fine for a couple of months now. All of a sudden the MergeData stored proc has started to finish prematurely before it has completed all of the processing it is supposed to do. The strange thing is that it doesn't raise any errors back to the windows service. It just seems to stop doing what it was doing before it has completed all of the processing and returns control to the windows service, which then carries on with the other stored proc calls. The even stranger thing is that if we then run the MergeData stored proc directly on the database it works fine and completes all the processing it was supposed to do. However, it gets even stranger. The same installation of the windows service that was used on our live server was installed on our test server, the same data export files were copied across and it works perfectly. The test server uses the same versions of .NET framework, Sybase OLEDB driver and Sybase database. So from the surface the test server looks to have exactly the same software on it - both the software we developed and the third party software we use. Why would a stored procedure not complete when run from an application (without throwing any errors) but work fine when run interactively from the database (without throwing any errors)? And why would the same version of the application on another environment work perfectly. Both the command and connection timeouts on our OLEDB objects are set to 20mins and this timeout is not being reached. The process finishes prematurely within about 9-10 minutes and then continues with the other stored procs. We've had timeout issues before but they have always thrown errors. Has anyone seen this sort of problem using ADO.NET, Sybase or the Sybase OLEDB driver? As you can see it's proving to be frustrating trying to logically conclude where the problem resides. Our code seems fine on the test server but doesn't seem to work on the live server. Therefore you'd think it would be an environment issue, however the MergeData stored proc works fine on the live server when run interactively from the database. Very confusing! :-) Sorry for the crosspost but I haven't a clue which bit of our system the problem resides in. Thanks for any help you can give, Steve Tag: rergarding assembly load error Tag: 78974

    - SOLVED: CaseSensitive and Guid / Find() I just though I would share with the group a small problem i ran into then solved after banging my head on the monitor for a few hours. For my dataset i have an XML schema that i load up. Its not quite a strongly typed dataset, i just look for scheama changes with my data adapter. Anyway.... In my dataset the primary key(s) of tables are uniqueidentifiers. Unfortunately some of the columns coming from the database are coming out as varchar() ..don't ask , i want them all as unique ID's. So looking at the XSD schema i'll see entries like <xs:attribute name="Record_GUID" type="xs:string" msdata:DataType="System.Guid, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> Loading up data into the dataset works fine. But, I found that some of the fields defined as above are of type System.Guid others are strings. Whats the difference ? If the field was a varchar in the DB and I forgot to run a Cast(Record_GUID as uniqueidentifier) operation on the column, then it shows up as System.String. Now here's the rub... values in the fields are of type string, but when you run a find on the object the compare seems to be binary ...that means it ignores the Table.CaseSensitive setting. So Table.Rows.Find( "2F79A7BA-9AD9-4D3E-835F-780FB2A9CE13") is different than Table.Rows.Find( "2f79a7ba-9ad9-4d3e-835f-780fb2a9ce13") even though the objects in the column are of type string. Anyway, i'm not sure if this is a bug, or if the data adapter that fills the schema should throw an error. I just hope this helps someone save a few tedious hours of debugging.

    - Random SQL Timeouts after Web Win2k3 upgrade. I recently upgraded our web server from windows 2000 to windows 2003. Our SQL server is a SQL 2k, Win 2k machine that has not been modified at all. Both have all of the most recent updates/patches. When I upgraded the web machine to windows 2003, we suddenly started having random timeout problems. Every few hours or so, every sql call from our web server would result in a timeout, or at least take a very long time. Then a few minutes later(anywhere from 5 to 30) everything would be fine again. Although it didn't make any sense that SQL would be causing the problem, I did run through the profiler, and everything seemed to okay there. There were no monster, life draining queries running at the start of every down time. So currently, my best guess is that it has got something to do with ado.net. Currently I'm running a strictly ASP site on the server. I've yet to utilize any of the .net functionality on this site, and we have no objects installed other than our eCommerce credit card verifier. I'm using the following connection string to connect to SQL: DRIVER={SQL Server};SERVER=10.10.10.10;NETWORK=DBMSSOCN;UID=username;PASSWORD=password;DATABASE=dbname Any help you can offer will be GREATLY appreciated. I've been spinning my wheels on this for a while. Thanks. Tag: rergarding assembly load error Tag: 78966

    - Data Import & Source Target DataType mismatch problem Hi All, I'm building app that reads data from the text files and then inserts it into SQL server table. When I read the text file into dataset, sometimes data type is not interpreted correctly. I'm using DataSet.Merge method to merge untyped dataset formed by reading the text file with typed dataset that has the schema of the database table. In the case when ODBC text driver does not interprete DataType correctly I compare the target column datatype with source column datatype in the dataset, if they dont match I try to change it but I'm getting exception stating, "column datatype cannot be changed once column has the data " which is perfectly right. Logically this operation should not be allowed but there has to be a way around. Has anybody got a way around this problem. Following are the alternatives I tried but seem to be inappropriate 1. DTS package to import text data. Doesnot work because text file contains odd number of columns, not all columns are imported. Also user edition is required before importing text file into database. 2. Create Dataset that has matching schema as that of table and clone source dataset row by row. This gets really expensive. I'm dealing with on an average 70MB of text data at a time. Can anybody suggest alternatives to this. Any help is really appreciated. Thanks, -HKM Tag: rergarding assembly load error Tag: 78953

    - Master/Detail relationship using ComboBoxes Hello! I'm wondering how to do Master/Detail relationship using ComboBoxes. I'm using VB (2003). I have DataSet containing tables called as 'State' and 'City' (not really 'State' and 'City' but idea is the same and easier to understand). I want user to select first 'State' of the ComboBox containing states and then the ComboBox containing cities should contain only cities for that selected state. I want to save only ID (.ValueMember) of the state and city to the database table. How to do this when using DataBinding? At the moment code looks like this ... '// *** 'State' ComboBox *** cbState.DataSource = ds.Tables("States") cbState.DisplayMember = "State" cbState.ValueMember = "ID" cbState.DataBindings.Add(New Binding("SelectedValue", myDataTable, "StateID")) '// *** 'City' ComboBox *** cbCity.DataSource = ds.Tables("Cities") cbCity.DisplayMember = "City" cbCity.ValueMember = "ID" cbCity.DataBindings.Add(New Binding("SelectedValue", myDataTable, "CityID")) ... and it's working fine, but I need to implement this selection relationship somehow. It should work also when myDataTable position changes - propably this is possible to do? -- Thank you in advance! Mika Tag: rergarding assembly load error Tag: 78914

    - How To Make A 'Safe' Flexible Query? I'm just about to make Yet Another Search Form For A DB Application. I'd just like to ask.. if I were able to search based upon a different number of columns, say sometimes firstname, sometimes lastname, sometimes both? what's the best way to create a query? Definetly not strSelect="Select * from Authors where " & QueryCol1 & "=@QueryValue1 and " & QueryCol2 & "=@QueryValue2" Or something to that matter right?

    - Very Slow Performance Hi, I used frontPage 2000 to build my websites which is hooked to MS SQL server 2000. Once I create an application from frontpage with the appropriate database settings and save it and finally Click "preview in web Browser", It takes too much time to display. I don't know when it will be displayed. The internet explorer 5's progress bar shows a fast performance intially and at some stage doesn't move and stays static. Once I stayed for over 1 hour to witness the result, but was in vain. It was still staying static. (note: Internet Speed is averagely faster which is using an ADSL connection) When I run my CGI applications, IE gives a "Internal Server Error" at some times or else produces "XML Rowset not found". What might be the problem? Have anyone experianced this problem? note that my CGI applications are made using Borland Delphi 5. Tag: rergarding assembly load error Tag: 78887

    - Odd connection issue - (yes I'm running in mixed mode authentication) Here is the scenario... - There are two sql servers: "Production" and "Staging". PLEASE READ THIS BEFORE REPLYING --> Both SQL servers are set to "SQL Server and Windows" mixed authentication mode. (I have verified this multiple times). Both Sql Servers have Named pipes and TCP/IP port 1433 installed under network client configuration - There is a development machine: "Development". Any machine we try to connect from using the following has the same behavior however. Problem: Cannot connect from ASP.NET app running on "Development" under the IUSER account to the "Staging" server using SQL Server authentication. Here is the connection string... "Server=Staging; Database=V2Staging; User=sa; Password=development" It throws the exception: System.Data.SqlClient.SqlException: SQL Server does not exist or access denied. at System.Data.SqlClient.ConnectionPool.GetConnection(Boolean& isInTransaction) at System.Data.SqlClient.SqlConnectionPoolManager.GetPooledConnection(SqlConnec tionString options, Boolean& isInTransaction) at System.Data.SqlClient.SqlConnection.Open() at SqlSecurityTest.WebForm1.Connect(String connectionString) in c:\inetpub\wwwroot\sqlsecuritytest\default.aspx.cs:line 57 at SqlSecurityTest.WebForm1.Page_Load(Object sender, EventArgs e) in c:\inetpub\wwwroot\sqlsecuritytest\default.aspx.cs:line 36 Oddity 1: We CAN establish a connection from the same ASP.NET app on "Development" running under the IUSER account to the "Production" using SQL Server authentication.. Here is that connection string... "Server=Production; Database=V2Production; User=sa; Password=production" Oddity 2: We CAN establish connections from the ASP.NET app on "Development" running under the NT AUTHORITY\NETWORK SERVICE account to BOTH servers using SQL Server authentication.. I have boiled this down to this question... Why should the windows account the application is running under imapct connectivity to a SQL Server at all when using SQL Server authentication and both sql servers are running in mixed authentication mode? This has been a thorn in my side for many days. I want to solve this problem and will set up a web page with screen shots or collect any information you might find useful to help me solve this problem.

    - DataGrid and DataSet information Hi, I have 2 parents tables (example : Car and Road). That Car can use n Roads and Road can be use by n Cars. In that case, I need a middle table because it is a n-to-n relation. So we had a Link_Car_Road table with the primary key of Road and Car as foreign key in Link_Car_Road. So if I want to design a form to show the car informations with all the road corresponding to that car, I need to use a DataGrid (I think, because it seems impossible with a ListBox). I am able to show the car ifnromations with the Link_Car_Road information, but I am unable to get the Road with my DataGrid. To do it, I set the DataSource of my DataGrid to my DataSet and my CalueMember to Car.Link_Car_Road_Relation. So when I select a new car record, I get all the child rows of Link_Car_Road that correspond to that car. IS there any way to get the Road information instead the middle table informations when I select a new car row ? Thank you for your help. Tag: rergarding assembly load error Tag: 78826

    - how to select by a binary column? Hello, I have a binary column in a .NET (C#) in-memory DataTable, and I wish to make a selection based (among others) on this column. It's easy to do such a thing on eg MS-SQL, but I want to do it in .NET's in-memory data. I tried to format the byte array in many ways (including the 0x0001 format of MS-SQL, but also 000-0001, {000-001}, [000-001], with or without quotes, but no way worked. Any idea how to do that? Please don't question why I would want to do that ;O) If I wasn't clear: DataRow[] matches = dsMyDataSet.Select("Column1 = " + value + " and Column2 = " + value2); where value2 is in fact a byte[], and Column2 contains a base64binary in my in-memory table.
