    - ASP Error on INSERT INTO Statement Hi I'm getting the following error: Microsoft OLE DB Provider for ODBC Drivers error '80040e14' [Microsoft][ODBC Microsoft Access Driver] The INSERT INTO statement contains the following unknown field name: 'ClientName'. Make sure you have typed the name correctly, and try the operation again. I have checked the database and the field names are correct. The IIS server has the appropriate permissoins to the database. When I run the query from Access it sucessfully inserts a row.

    - File access question Hello folks, I am experiencing a rather strange problem. I have written a service that attempts to open a file on a network share. When I try to open the file from my service, I get the "Access is denied" error. However, if I try to open the file from a GUI application, I can open the file without problem. I've tried using the FileIOPermissions object to get around the error with no luck. Obviously I am missing something very fundamental, the file is accessible to 'Everyone'. Does anybody know what I am doing wrong? Thank you, Jason Tag: ASP Error on INSERT Statement Tag: 97732

    - ADO add to database problem, help? Okay so i'm having some trouble with adding to my database through the dataset. i can read from it and it prints just fine, i run the code okay with no errors, but it simply doesn't add the record, i've left it simple here just so i can get it right before i start adding the extra functionality. okay so the table name is UserID, and i want to add into the table, what am i doing wrong? private void btnAddRecord_Click(object sender, System.EventArgs e) { OleDbConnection AddConnection = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\salesleadmgmt.mdb"); OleDbDataAdapter addAdapter = new OleDbDataAdapter("Select * from UserID", AddConnection); DataSet addSet = new DataSet(); DataRow addRow; OleDbCommandBuilder addCommandBuilder = new OleDbCommandBuilder(addAdapter); addAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey; addAdapter.Fill(addSet, "UserID"); Console.WriteLine("i was able to load the userid table."); addRow = addSet.Tables["UserID"].NewRow(); addRow["UsrName"] = "Bob"; addRow["passwr"] = "Bobpwd"; addRow["UsrID"] = "6"; addSet.Tables["UserID"].Rows.Add(addRow); Console.WriteLine("i inserted the new values"); } this runs in the .CS file, i don't get any of the write lines or anything, it does run on a button click, i have another button click that works fine, i'll show that one, whats wrong with this first one? working display click [code:1:e515321317] private void Button1_Click(object sender, System.EventArgs e) { string ConnectString =@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\salesleadmgmt.mdb"; OleDbConnection CustConnection = new OleDbConnection(ConnectString); CustConnection.Open(); DataSet CustSet = new DataSet(); OleDbDataAdapter CustAdapt = new OleDbDataAdapter("SELECT * FROM CustInfo", CustConnection); CustAdapt.Fill(CustSet); CustConnection.Close(); CustGrid.DataSource = CustSet; CustGrid.DataBind(); } [/code:1:e515321317] *-----------------------* Posted at: www.GroupSrv.com *-----------------------* Tag: ASP Error on INSERT Statement Tag: 97727

    - Moving CurrencyManager to specific row in Data Source I have a series of user-bound controls that are associated with a dataset, and need to be able to move the displayed data row in one control based on events in another. I have all of the controls bound to the same dataset on my form, and the navigation controls are passing a complete DataRow object in the event arguments. I know I need to get the CurrencyManager for the binding context, and set it's Position, but it's not working properly. The code I am currently using follows (Names have been changed to protect the innocent :). I have a strongly typed dataset called "TypedDataSet" with a table called "Table" in it. The table has an "ID" column which is the primary key. The data is being read into the dataset from an XML document. /**********/ TypedDataSet ds = _dataSet; TypedDataSet.TableRow row = e.nodeData as TypedDataSet.TableRow; int pos = ds.Table.DefaultView.Find(row.ID); CurrencyManager cm = BindingContext[ds, "Table"] as CurrencyManager; cm.Position = pos; /**********/ When I run this code, the data-bound controls do move to a new row. But it's always the wrong row. The problem appears to be that the DataView has the rows sorted differently than the DataTable. I have tried explicitly sorting by primary key (DefaultView.Sort = "ID ASC") as well as using the default (DefaultView.ApplyDefaultSort = true), but the results are identical. The DataTable.Find() method doesn't appear to be useful, since that returns a DataRow -- that I already have -- but I have no way to move the CurrencyManager to a specific data row object, only to a specific position. I'm sure there's some .NET property or method I'm missing but I can't seem to find it. Any ideas? --Mike 's/not.//g' to email me. Tag: ASP Error on INSERT Statement Tag: 97726

    - VB.Net (ADO): Thoughts on Copying 7 tables to 1 table 2 Part Question: I've a VB.net application where I read information from 7 Tables in a MS Access Db. There is a performance hit when this happens (about a 1-2 second hit per table). So I'm going to combine the relavent parts of each table into a single table in a "new' MDB file. I've experimented with this and found that the best way that I can see is to gather the information from each table into an Array and then dump that info into my new MDB file. I want all the 7 tables starting with the FIRST row in the new table. I first get the number of rows for a table, re-dim my array and gather the info. Then I repeat for the next table - I compare table row lengths to make sure my Array does not get smaller than the maximum table row found. All appears to work fine. Question #1: Can someone suggest a better way (if there is one) to take the "selected" columns from a single MDB (having 7 tables) into a new single MDB with 1 table. I tried reading each of the 7 tables into my new MDB, but this doesn't work as each table adds new rows past the previous table information. Question #2: Every now and then, I find one of my columns (about mid way down) has a bunch of NULL cells when the data should be continuous in the column. I run the application again (maybe a third time) and all is OK. All the other columns are OK (and the code is similar). A head scratcher for me. Any thoughts? Thanks in advance.

    - Access datetime format problem? I'm generating 2 datetime values inside a VB.Net program say datetime1 and datetime2. datetime1 is retrieved from an Access database from a column of datetime type. datetime2 is generated internally by the program. I want to test the condition: If datetime1=datetime2 then CodeBlock But CodeBlock never seems to get called even when I'm sure that datetime1 and datetime2 are identical. If I look at the identical datetime1/2 values I do see a difference in formatting in the time part: datetime1 (from Access) shows time as eg 11:59:59 PM datetime1 (internally set) shows time as eg 23:59:59 Question is: Am I trying to test identity of the datetime values in the wrong way or is the problem the difference in time formatting? If the latter then is there some way I can set the database to return datetime values using 24 hour clock times? TIA JGD Tag: ASP Error on INSERT Statement Tag: 97722

    - ExecuteNonReader hangs Hello everyone, my webservice read from (and write to) Oracle queues. It uses the Oracle Data Provider downloaded from Oracle site (Oracle10g Data Provider for .NET 10.1.0.2.0). Webservice calls a stored procedure that executes the read operation. Sometimes the ExecuteNonReader() hangs (I'd like to set a timeout on command, but OracleCommand does not support this option). Consequently the webservice fails for timeout. I tested the same class without using webservice and it doesn't hangs. Do anyone know what is the problem? Is it a bug? I'am using .NET 1.1 on Windows 2003. Thanks, Gionni Tag: ASP Error on INSERT Statement Tag: 97717

    - How to you page and sort large dataset result in datagrid? In ASPNET 1.1 Is there a good way to page/sort VERY large Result set in datagrid > > > > > > P. Wilson blog wrote: " Here's a stored procedure that I use for sorting and paging large recordsets in SQL Server, as opposed to using the more common and terribly inefficient entire dataset approach in .NET. It certainly doesn't matter much in the little classroom examples of a few hundred, or even thousands, of records, but working with larger recordsets with datasets is just bad. This is even more true with ASP.NET, since the entire dataset is usually saved in viewstate, and since the web server is doing the processing for many users. This stored procedure is certainly not the only way to do sorting and paging in SQL Server, but it is probably the most efficient, although proper indexing is still required to avoid table scans. Note that this does not use temporary tables, which are convenient but not as optimal -- this also means you could modify this to be dynamic SQL for Access or other databases! The parameters are the name of the table, the name of the primary key (necessary for the little bit of optimization included), the name of the sort field (or sort fields, with or without ASC/DESC), and the page size (number of records). It also allows optional parameters for the page index (defaults to 1st page) and a query filter (defaults to null) so you can sort and page through filtered records only! Note that it returns two recordsets -- the first is the results you expect, and the second recordset is a scalar with the number of total pages so you can better define the GUI pager for a grid. This is relatively easy to integrate with the ASP.NET datagrid if you use custom paging and sorting, and it will minimize both your load on the server and the amount of data sent to the client's browser! By the way, this code is just modified from some I found on the net, and there are certainly some minor optimizations that can be done, like using different sql for the first page.

Reducing the number of columns in the select statement always speeds things up, even for aggregate operations like Count. Very interesting though; I will have to see how well it works for complex queries. # re: Sorting and Paging Recordsets in SQL Server Torbjörn Axelsson Posted @ 10/27/2003 11:14 AM Very interesting! Right now I'm using a solution based on creating a temporary table in the stored procedure for selecting rows from a table containing over a million rows. I will test to implement this solution and see if it boosts performance, which would be very welcome :) In my project I will have to make an inner join to retrieve User names from another table, but since I only have to do this on the outermost SELECT-statement (after TableName), and I have a good indexed structure, that shouldn't have a big impact on performance.

    - Linebreaks in SQLCommand.CommandText (C#) Hi, From a C# application I read the SQL text from a text file. The text file contains line breaks that need to be conserved. The text file is read by a streamreader and added to a StringBuilder object. Each line in the text file is read, one at the time. After reading a line, I add a carriage return/linefeed by System.Enviroment.NewLine. But carriage returns / linefeeds are added to the StringBuilder as "/r/n". When I add the content of the StringBuilder object to the SqlCommand.CommandText property and run the query, the SQL fails. I have done a similar thing in VB. In VB I added carriage returns/linefeed by the "vbCrLf" constant. This worked fine. Line breaks were added and maintained when passing the SQL to the SqlCommand.CommandText property - no codes were "visible". I hope someone knows how to handle this in C#.

    - SQAL question Sorry, but I didn't find a group for SQL questions. May be someone can answer here. In my app I want to reflect a hirarchy in a tree view. Therefore in the database I have a table like this: HirachyId (primary key) ParentHirarchyId (key to reflect the arent entry) CategoryId (a foreign key into a category table) Content may be like the following (0 is root hirarchy) 1 0 10 2 0 11 3 1 16 4 1 8 5 3 27 6 3 28 0 +-- 1 | +-- 3 | | +-- 5 | | +-- 6 | | | +-- 4 | +-- 2 Now I want a SQL-select statement which "recursive" gives me all records for a given node, i.e., when the node is "1" I want to get the records 1 0 10 3 1 16 4 1 8 5 3 27 6 3 28 Can this be done with a SQL-statement? -- Sleepless in Berlin Wernfried Tag: ASP Error on INSERT Statement Tag: 97693

Supposing i have a table, 'contacts' whose fileds are like this : Contactid(autoname), customerid(FK from another table), contactname(char)... Here customerID is a foreignkey from tables 'Customers'. Since names might repeat in this table, how do i list the names when a search is made on this name. I want to display the fields displayed in row. I tried with findrowview, but could not succeed.

    - Paging a DataGrid or similar control...? I have a windows application that returns 10s of thousands of rows to a DataGrid (for all intents and purposes you can assume that it's a DataGrid, I'm actually using the Infragistics UltraWinGrid though). Due to the ever growing amount of data I want to implement some sort of record paging. There are a lot of examples for ASP.Net but not many for windows applications. I am planning to use some of the techniques used for ASP.Net, but I was hoping someone out there may have a few suggestions specifically for a windows application.

    - ADO.NET 'HasMoreRows' and 'HasMoreResults' I am writing an ADO.NET C# com control wrapper for the old VBSql control used in an large application we have. The wrapper emulates the VBSql controls interface and is intended to allow us to move to SQL2000 from 6.5 without resecting the application and re-writing all the logic within the application to ADO. ************************************* The call semantics for VBSql are as follows set sql command call exec for command call results to check for data arrival. Call One while call results != noMoreResults Call Two+ while call nextRow != noMoreRows loop nextRow loop results ************************************* The problem is that because we have to call results once initially for each call to exec, I need to skip the initial call in the .NET code to DataReader.NextResults(). Then the second call comes in and I need to skip it again as I am not ready at this point to move to the next result set. Then the third call comes in and now, I am ready to forward the results set and return nomoreresults or success if there is a second result set. In order for me to do this, I need to keep a counter on the call to DataReader.NextResults() and only actually call NextResults on the third call. But this causes problems when I use a SQL insert command as I just want to know if the command was successful on the first call, and when I want to skip any remaining records in the batch and move onto the next batch. It would solve my problem to be able to know if I have rows or results remaining without calling NextResults() or Read() as they always move the cursors(or whatever) on the sql side. There are two undocumented, private Boolean properties on the Reader I would like access to. They are 'HasMoreRows and 'HasMoreResults'. I have not been able to find a way to get around the 'private' access modifer on these properties as my old trick of "#define private public" (crazy I know, but sometimes it is the only way to move forward in a timely fashion) is not available in .NET to my knowledge. I am sure someone else has had issues regarding the inability to check state of the reader without moving record or result pointers in the process. To check if I have more rows, I have to call read, or the hasRows. But hasRows returns true if I have another result set pending and thus need to call NextResults. So, I have to mangle the NextRow method to include a call to NextResults when the Read method returns false so the next call to the vbsqls results method will return the correct state without actually calling NextResults in the vbsql results stub in the wrapper. Thanks, and hopefully that is legible! Tag: ASP Error on INSERT Statement Tag: 97640

    - Access database, network access problems I've recently run into a problem when creating a web service. I have a webserivce that returns data from a small access database; I created and tested the service on my local machine with the database local in a sub-directory. I verified the results on a test server remotely with the database stored on the local disk. The production server is a web farm, a SAN provides all data storage for this farm; This is where I am having problems, I'm no longer able to open the database, the permissions have been validated on the remote share and the user account has access? My connection string "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=\\server\share\folder\folder\folder\database.mdb;" I have also tried using the extended property Mode="Share Deny None" The mappath function is used to get the actual file path. It points to the correct location, but, I get errors that the database cannot be opened because you don't have permissions or the database is being opened exclusively, or something to that nature. I don't have recordlocking enabled and a .ldb file is never created. Any suggestions? If you need more information please let me know. Tag: ASP Error on INSERT Statement Tag: 97621

    - how to correctly map multiple datasource tables to typeddataset ta I foolishly thought that if.. 1. I have a typed dataset built from my data source schema (that is, all the table names and all their column names, and types, match), and 2. I fill an instance of the dataset using a dataadapter, then the table names in the dataset would be correct (i.e. matching data source table names). I found that they are named Table, Table1, Table2, etc, and that to override this I need to set up table mappings for these default table names (which are dependent on the order of tables in the query text!). Is there a correct way to do this, or is the proper technique simply to map the default table names!? Tag: ASP Error on INSERT Statement Tag: 97607

    - Inheritance VB.NET Hi guys, Wonder if anyone can help a newbie in VB.net. I've done a substantial amount of work in VB6 and to promote code use, I lent some methodology from some other OOP RAD tools - but I'm having a probem figuring out an approach in VB.Net... In VB6, I would, for each database table, create a 'class module', which contained all of the necessary database functions I required. So, e.g. I would have a class module called 'tcProvinceState', which would handle all of my database IO for the ProvinceState table. In each class module, I would have functions such as 'DoSelect', 'DoSelectRow', 'InsertRow', 'UpdateRow' and 'DeleteRow'. Here are some examples of the type of thing I currently do; Public Function Do_Select(pSearchString As String) As ADODB.Recordset ' Select all records from the table sSQL = Do_Select_Body(pSearchString) 'Get the body sSQL = sSQL & " ORDER BY PS.PROVINCE_STATE_NAME" Set Do_Select = clsSQL.Perform_SQL(sSQL) End Function Private Function Do_Select_Body(ByRef pSearchString As String) As String ' Get the select body sSQL = "SELECT" sSQL = sSQL & " PS.ID" sSQL = sSQL & ", PS.CODE" sSQL = sSQL & ", PS.PROVINCE_STATE_NAME" sSQL = sSQL & ", PS.COUNTRY" sSQL = sSQL & ", PS.GMT_ZONE" sSQL = sSQL & ", PS.TAX_GROUP_ID" sSQL = sSQL & ", TG.CODE AS TAX_GROUP_CODE" sSQL = sSQL & ", TG.DESCRIPTION AS TAX_GROUP_DESCRIPTION" sSQL = sSQL & ", PS.FREIGHT_ADJUSTMENT" sSQL = sSQL & ", PS.RECORD_CREATED" sSQL = sSQL & ", PS.RECORD_UPDATED" sSQL = sSQL & ", PS.USER_ID" sSQL = sSQL & ", EL.USER_NAME AS EMPLOYEE_USER_NAME" sSQL = sSQL & ", EL.FIRST_NAME AS EMPLOYEE_FIRST_NAME" sSQL = sSQL & ", EL.LAST_NAME AS EMPLOYEE_LAST_NAME" sSQL = sSQL & " FROM ((" sSQL = sSQL & "PROVINCE_STATE AS PS" sSQL = sSQL & " LEFT JOIN EMPLOYEE_LOGIN AS EL ON PS.USER_ID = EL.ID)" sSQL = sSQL & " LEFT JOIN TAX_GROUP AS TG ON PS.TAX_GROUP_ID = TG.ID)" sSQL = sSQL & " WHERE 1=1" Build_Search pSearchString Do_Select_Body = sSQL End Function Public Function Insert_Row(ByRef rsRow As ADODB.Recordset, pID As Long) As Boolean ' Insert row into the table; Dim sErrors As String Dim sDate As Variant sDate = Format(Now(), "d-mmm-yyyy") ' Use Stored Procedure (SQL Server 2000) ' Initialize the input & output parameters; Set cStoredProcedure = New ADODB.Command Set cParam = New ADODB.Parameter With cStoredProcedure Set cParam = .CreateParameter("@CODE", adVarChar, adParamInput, 4, rsRow.Fields("CODE")) .Parameters.Append cParam Set cParam = .CreateParameter("@PROVINCE_STATE_NAME", adVarChar, adParamInput, 30, rsRow.Fields("PROVINCE_STATE_NAME")) .Parameters.Append cParam Set cParam = .CreateParameter("@COUNTRY", adVarChar, adParamInput, 20, rsRow.Fields("COUNTRY")) .Parameters.Append cParam Set cParam = .CreateParameter("@GMT_ZONE", adSmallInt, adParamInput, 5, rsRow.Fields("GMT_ZONE")) .Parameters.Append cParam Set cParam = .CreateParameter("@TAX_GROUP_ID", adInteger, adParamInput, 8, rsRow.Fields("TAX_GROUP_ID")) .Parameters.Append cParam Set cParam = .CreateParameter("@FREIGHT_ADJUSTMENT", adCurrency, adParamInput, 8, rsRow.Fields("FREIGHT_ADJUSTMENT")) .Parameters.Append cParam Set cParam = .CreateParameter("@USER_ID", adInteger, adParamInput, 8, glngUserID) .Parameters.Append cParam Set cParam = .CreateParameter("@ID", adInteger, adParamOutput, 8, pID) .Parameters.Append cParam sSQL = "SP_PROVINCE_STATE_INSERT" clsSQL.Perform_StoredProcedure sSQL, cStoredProcedure, sErrors End With ' Check Errors If Len(sErrors) Then Display_Errors "Insert Failed", sErrors Insert_Row = False Exit Function End If ' Read any output parameters pID = cStoredProcedure.Parameters("@ID").Value Insert_Row = True End Function With this method, creating a new table and its related 'class' is quite simple. Now, although this methodology doesn't have true inheritance, I get some code re-use and it provided a very good platform for my DB applications. However, I am now somewhat confused with regards to VB.Net. .Net would appear to give me some native functionality for things such as selects, inserts and deletes. I can see how inheritance may truly help me by allowing me to create a 'master class', but I'm not sure how I would implement this? - Should I be looking at writing similar code? or does .Net offer me another option? Ideally I would like to create a visual class such as a dataset - but from what I can see - this has to be copied from form to form as required - not inherited. Anyway, if anyone has any suggestioms, or can point me in the right direction, I'd very much appreciate it. All the best, Graham Tag: ASP Error on INSERT Statement Tag: 97605

    - Recommended OleDB driver for MySQL? I am accessing MySQL from VS 2003, C# and ADO.NET, using the OleDb interfaces (not ODBC) and have been using (successfully) an OLE DB driver on: http://www.mysql.com/downloads/download.php?file=Downloads/Win32/MyOLEDB3.exe&pick=mirror This driver is called "My OLEDB 3.0, OLE Provider for MySQL, February 20, 2001". I am actually amazed that anything written in 2001 still works with the recent MySQL 4.1 ... amazed - and worried that some of the issues I am working through may be caused by some incompatibilies ... Should I be using a more recent driver? I see mysql-connector-net-1.0.0-beta.zip on www.MySQL.com but this package doesn't contain any EXE (and I don't whether one can be built from the included file or how). I am not even sure this is an OLE DB provider, it may be an ODBC provider. In fact, considering how new I am to MySQL, I am not even sure that *any* MySQL OLE DB provider is required: the Windows System Requirements page (http://dev.mysql.com/doc/mysql/en/Windows_system_requirements.html) does not even mention the need to install anything before proceeding with the MySQL installation (except for those planning to connect via ODBC).

    - DataTable.Add(row) and fired events I have a situation where a method listens to the RowChanged event for a datatable. The problem I having is this.. The RowChanged event handler calls another method, passing in the e.Row["ID_VALUE"] of the row that fired the event. In the case where this is a .Add(dr) that has caused the RowChanged event to fire.... the row that is referenced in e.Row (event arg for the RowChanged event handler) is not actually in the table yet. If I do a dt.Select() or a dt.Rows.Count,,, it is obvious that the row firing the event has not actually been added to table yet. Why is this happening? Is this a bug? Why would the row fire the table event and not be in the Rows collection for the table??? Tag: ASP Error on INSERT Statement Tag: 97584

    - OracleClient exception... Hey guys, I'm stumped on this... Today I was asked to look into coverting our ODBC access to a Oracle database to the client that microsoft wrote and have come up against the lovely "ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'MSG_DATAREAD' " message... All I'm doing is converting the code from the stuff that's using OdbcConnection/Command etc to OracleConnection/Command etc so I know the stored procedure's all work fine. Here's the code that's failing: ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ' get a reader for the record set with this msg number Dim dbcommand As OracleCommand = New OracleCommand dbcommand.Connection = dbData dbcommand.CommandType = CommandType.StoredProcedure dbcommand.CommandText = "MSG_DATAREAD" ' get a cursor out Dim param As OracleParameter = New OracleParameter param = dbCommand.Parameters.Add("RC1", OracleClient.OracleType.Cursor) param.Direction = ParameterDirection.Output ' pass in the msg number Dim msgnumParam As OracleParameter = New OracleParameter msgnumParam = dbcommand.Parameters.Add("MsgNumber", OracleType.VarChar, 50) msgnumParam.Direction = ParameterDirection.Input msgnumParam.Value = NullToBlank(m_szCurrentMsgNumber) Dim dbReader As OracleDataReader = dbcommand.ExecuteReader While dbreader.Read ' do some stuff with the data I get back End While dbreader.Close() ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' Here's the Stored Procedure it's calling: /* Stored procedure MSG_DATAREAD ------------------------------------------- */ ( MsgNumber IN VARCHAR2 DEFAULT NULL, RC1 IN OUT Omwb_emulation.globalPkg.RCT1 ) AS MsgNumber_ VARCHAR2(50) := MsgNumber; StoO_selcnt INTEGER; StoO_error INTEGER; StoO_rowcnt INTEGER; StoO_crowcnt INTEGER := 0; StoO_fetchstatus INTEGER := 0; StoO_errmsg VARCHAR2(255); StoO_sqlstatus INTEGER; BEGIN NULL; /*[SPCONV-ERR(6)]:(set DATEFORMAT) Manual conversion required*/ OPEN RC1 FOR SELECT MsgNumber , MsgItem , Section , Field , Data FROM MSG_Data WHERE MsgNumber = MSG_DATAREAD.MsgNumber_ ORDER BY MsgItem ; END MSG_DATAREAD; Tag: ASP Error on INSERT Statement Tag: 97559

    - Setting Textbox to Null for DateTime I have a textbox on a windows form which is bound to a smalldatetime field in a Dataset. The problem is that sometimes this date should be deleted so that a null value gets written back to the database. However, if I delete this date and leave the Textbox the previous entry gets retrieved. Is there a way to prevent this from happening and leaving the textbox empty so that a null value gets written back to the database when update is called? Tag: ASP Error on INSERT Statement Tag: 97551

    - Date/Time in Access I'm having trouble storing the value of Now in an Access table. I'm using VB.NET 2002. I need to store a time value, but no matter what I do I end up getting just a date value in Access. I'm doing something like this: Dim NewRow as DataRow = MyTable.NewRow NewRow("InTime") = Now MyTable.Rows.Add(NewRow) DataAdaptor.Update(MyTable) The value of CDate(NewRow("InTime")) is correct until I refresh the dataset with data from the database. All I get is the correct date and a time of 12:00:00. I've tried using every possible format of Date/Time in Access, including my own custom format. Thanks for the help Tag: ASP Error on INSERT Statement Tag: 97550

    - Delete datarowview objects from a dataview Hi all, I have a problem when attempting to delete datarowview obecjts from a data view Dim mydv As New DataView Dim thisDRV As DataRowView mydv.Table = myDS.Tables("CountedItem") mydv.RowFilter = "ilID = '" & lID & "'" For Each thisDRV In mydv thisDRV.Delete() Next When I execute this code I get an IndexOutOfRangeException exception. However, if I print the first column of the datarowviews they all exist. Dim mydv As New DataView Dim thisDRV As DataRowView mydv.Table = myDS.Tables("CountedItem") mydv.RowFilter = "ilID = '" & lID & "'" For Each thisDRV In mydv debug.writeline(thisDRV(0)) Next Is there something funny happeneing with the deleting of a datarowview from a dataview? Is this the correct way to delete a subset of rows from a datatable? Many thanks, Jason. Tag: ASP Error on INSERT Statement Tag: 97546

Hi

I'm getting the following error:

Microsoft OLE DB Provider for ODBC Drivers error '80040e14'

[Microsoft][ODBC Microsoft Access Driver] The INSERT INTO statement contains
the following unknown field name: 'ClientName'. Make sure you have typed the
name correctly, and try the operation again.

I have checked the database and the field names are correct. The IIS server
has the appropriate permissoins to the database. When I run the query from
Access it sucessfully inserts a row. Thanks for your help and here is my code:

set objCmd = server.CreateObject("adodb.command")
set objCmd.ActiveConnection = oUnifiedConn

DIM strTest
strTest = "INSERT INTO Client (ClientName) VALUES ('" & strName & "');"
response.Write strTest

objCmd.CommandText = strTest
'objCmd.CommandType = adCmdtext
objCmd.Execute ' line 82

Thanks

Mark

Make sure that local windows aspnet account has enough privileges to
database (this is the account which is used by default).
