 - ASP.NET SQL Server Please pardon my ignorance on this one, but here's what I'm trying to do: I have a table in a SQL Server 2000 DB called distributors. I've got an ASPX which has a text box, a button, and two labels. In the textbox, the user is to enter a "distributor id", then click the button. The button should query the distributors table for a matching distributor id, and return two prices, which is what the labels should reflect. Right now, though, I'm not even trying to match up the distributor id. The table has only one record in it at this time. This is what I'm doing right now: sqlConnection1.ConnectionString = blah blah blah; sqlSelectCommand1.CommandText = "SELECT distid, colorprice, blackprice FROM dbo.distributors"; sqlSelectCommand1.Connection = sqlConnection1; private void Button1_Click(object sender, System.EventArgs e) { sqlConnection1.Open(); sqlDataReader MyReader = sqlSelectCommand1.ExecuteReader(); Label1.Text = MyReader.getSqlMoney(1).ToString(); Label2.Text = MyReader.getSqlMoney(2).ToString(); sqlConnection1.Close; } As you can see, right now, I'm not even trying to match up the distributor id. I'm just trying to get the prices for the one record that's there. After I get that working I'll want to start matching up the distributor id. The error I'm getting is: Invalid attempt to read when no data is present. Any ideas? Thanks! Scott Tag: Active Directory Related Question. Tag: 69618

 - Connection String vs DSN, what to use and why? Which is better to use a connection string or DSN? Why? It seems like using a connection string is recommended but what exactly are the reasons for this? Also, one of the nice things about DSN's is the ability to quickly change what database your app is pointing to. How is this done with connection strings? Registry entries? I thought I read somewhere connections strings being held in the registry should be encrypted, how should this be accomplished? Is there a semi-standard way of doing all this?

 - DataAdapter.Fill very slow I am currently having a problem with a DataAdapter.Fill performing very slow or timing out. Our code is written in C#, platform Windows 2003 and the database is SQL Server 2000. However after reviewing other postings this seems to be an ado.net problem and not tied to SQL Server. groups.google.com search: DataAdapter Fill Slow We use Typed DataSets and stored procedures in our code. The query is very simple. It queries three tables that are left joined and has a where clause for an ID, and two dates. The tables have been indexed appropriately. I have tried multiple things to include: Changing from Typed DataSets to the regular DataSets. Creating performance counters to see what is happening on the machines. Running the query in Query Analyzer and Enterprise Manager runs in .5 seconds or faster. Changed databases and machines. Rebooted machines, refreshed SQL Server services, restart SQL Server. When I debug in DotNet it always points to the Fill of the DataAdapter. If anyone has any suggestions it would be appreciated. Tag: Active Directory Related Question. Tag: 69575

 - newbie vb6 ADO to vb.net ado.net, paging Hi, I am converting an existing VB6 webclass app to VB.NET ADO.NET and I'm having a problem coming up with solution for paging the records returned from my stored procedures. As I understand it from the help I can use a dataadapters fill() method to specify a page size and tha page I want. However this will only return 1 page worth of data. Currently in my web pages I provide next/back links and a <SELECT> list of page numbers. If I use the dataadapters fill() method to do the paging how will my code be able to workout how many pages there are all together? I looked at: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconpagingthroughqueryresult.asp ... but that doesn't seem to fit what I want to do. In ADO it was simple now it seems to be a lot harder. I realise that ADO.NET is built for performance and so doesn't come with as many built in features but some examples of ADO to ADO.NET in the area of paging would of been handy. Anybody done the same leap from ADO --> ADO.NET and done paging? Regards, Peter Tag: Active Directory Related Question. Tag: 69573

 - Combobox vertical scroll position Does anyone know how to determine the slider position (i.e. relative to the min and max values) of a combobox's vertical scroll bar (i.e. maybe a win api call?). I am trying to feedback the list's value as the user's scrolls the combobox (the list is too large to fill the combobox). I can't find any way to get this information. I seem to recall that in VB 6.0 this was available in one of the scrolling functions. If there is no way to get this info in vb.net, I would like to build my own combobox with textbox, listbox and vertical scroll bar. However, the problem then becomes how to make the vertical scroll bar look like the combobox scroll bar (I like the appearance of the latter when running on XP).

 - Adding rows to dataset (a.k.a. can an MVP help me please!) I'm totally lost here.... I have a blank typed dataset designed to hold invoice data, OK? The dataset has two tables, InvoiceHeaders and InvoiceLines. The invoice data is generated by a system/36 emulator and therefore comes in as a comma-delimited text file. My task is to get the text into the dataset so I can bind it to a crystal report and print the invoices. SO: I open the header text file, and go into this loop to attempt to fill the header table: Dim Ivc as New IvcDataSet Do While Not EOF(1) Dim x As IvcDataSet.InvHeadersRow Input(1, x.InsuredNo) Input(1, x.Item("EntryMonth")) Input(1, x.Item("KeyerInit")).... Ivc.Tables("InvHeaders").Rows.Add(x) x = Nothing Loop When I run the code, I get an error on the first input line because x is not set to an instance of an object. Being familiar with this type error I change the Dim line to read: Dim x As New IvcDataSet.InvHeadersRow Now, I have a blue squigly under the x that says "Argument not specified for parameter 'rb'..." or something like that. I find out that the rb is a System.Data.DataRowBuilder object. So I turn to the MSDN library to find out about the DataRowBuilder class. My research reveals that, according to MSDN, "This type supports the .NET Framework infrastructure and is not intended to be used directly from your code." So how the hell am I supposed to add rows to my datasets???? Tag: Active Directory Related Question. Tag: 69559

 - DB Locking Hi, I have an application framework which consists of several webservices, webpages and application all of which use a couple of MS Access database. We are currently in the testing phase of the project so we don't want to have to upgrade to SQL Server yet. The problem is that when the webservices or applications open the connections to the databases they open it in single user mode. No matter what connection strings I use they still refuse to open in multi-user mode. This is the connection string I'm using: "Provider=Microsoft.Jet.OLEDB.4.0;Password='';User ID=Admin;Data Source=E:\BORG\TypeProcessor\TypeProcessor.mdb;Mode=Share Deny None;Jet OLEDB:System database='';Jet OLEDB:Registry Path='';Jet OLEDB:Database Password='';Jet OLEDB:Engine Type=5;Jet OLEDB:Database Locking Mode=1;Jet OLEDB:Global Partial Bulk Ops=2;Jet OLEDB:Global Bulk Transactions=1;Jet OLEDB:New Database Password='';Jet OLEDB:Create System Database=False;Jet OLEDB:Encrypt Database=False;Jet OLEDB:Don't Copy Locale on Compact=False;Jet OLEDB:Compact Without Replica Repair=False;Jet OLEDB:SFP=False" Can you suggest anything?

 - CAN ANYBODY HELP?! Could anyone help me with the following problem! I open an SqlConnection. Then: 1. execute a reader on SqlCommand and get data through that reader; 2. in a certain time I call Cancel() method on SqlCommand and SqlDataReader.Close(). If I perform steps 1 and 2 several times (sometimes it happens even from the first time) I get the error which says that SqlConnection is closed. And it is. So, seems that SqlCommand.Cancel() in combination with SqlDataReader.Close() forces the connection to close. I can't determine the reason why it happens. Can I control somehow this behaviour, because I need the connection to be opened. Thank you in advance, Sergey. Tag: Active Directory Related Question. Tag: 69549

 - ADO.NET/SQL Mystery In using two different SQL Database server (one for development and one for production) a call to a stored procedure is storing incorrect data. We use ADO.NET SQL Data Adpaters and have set the stored procedure parameters. Tracing through on the debugger shows the correct data in the dataset but the SQL Profiler shows that the second parameters is coming in as a -1 (which is not the data in the dataset). To make matters worse this only occurs on the Development sever with the production server executing without error.

 - Selecting from DataGrid and passing to... Here's my situation. I have a data reader and datacommand (ASP.NET and SQL database). I have a search form which gives me the results in a data grid. Usually 2 or 3 results (persons) with various information (Name, Surname, Address...) What I want to do is to select a row in that datagrid (after I do the search and get results in a Datarid) and transfer the selected row to to next page and insert the selected data from that row in a text boxes. I need you to point me in the right direction on how to do that. Thanks. Tag: Active Directory Related Question. Tag: 69508

 - dataform wizard problems I've used the dataform wizard any number of times, and it works on all but one kind of microsoft access database. The style I use is text boxes for each column, with all the buttons. I just used the wizard on the customers table in the northwind.mdb that comes with office 11. Worked fine. Most importantly, when I clicked the add button, all the text boxes were cleared and and record count says 92 of 92 records(there are 91 records to start in the customers table). I created an mdb (access 2003) with one table from a larger database. It's called datetypes, and the table is called datetype. It has 5 columns. ID autoincrement integer DateType string 255 characters CreateDate Date default Now ChangeDate Date default Now Active Boolean default True All fields are required. When I run the form created by the dataform wizard on this table, the behavior is different. If I click Add, the text boxes(and checkbox for the boolean column) do not clear. Furthermore the recordcount (there are 9 records to start), says 1 of 10. If I press cancel, nothing happens, it still says 1 of 10. If I remove the faults, the same thing happens. If I remove required for all the columns except the ID autoincrementing key field, the same thing still happens. Furthermore, this happens with any of my tables in which the primarykey is an autoincrementing integer. Any ideas? Dennist Tag: Active Directory Related Question. Tag: 69505

 - Error in INSERT INTO statement When I run the simple code below I get the following error message: Type = System.Data.OleDb.OleDbException Message = Syntax error in INSERT INTO statement I've tweaked the insert to statement every which way. All the other ways create earlier error messages. I've compared this insert to statement to many I've seen in the book ado.net core reference, as well as other books.

 - newbie: bindingcontext prb I have created a C# app which allows editing of some database tables in a form. The form has several controls (text boxes, list boxes, etc), bound to a dataset with some tables into it; whenever the user requests a specific record from a list, the connection is opened and data are retrieved for the single record and all the related ("children") tables; the controls are filled and user can edit them. When the user wants to store its data into the source database, I do the following: 1) call BindingContext[myDataSet, "SomeTable"].EndCurrentEdit() for each table in the dataset 2) call Update for each data adapter 3) call AcceptChanges if nothing went wrong Anyway, sometimes I get an "object reference not set to instance of an object" exception from some of the instructions at (1), i.e. the requested BindingContext is null. What I'm doing wrong here? Thanx to all! Tag: Active Directory Related Question. Tag: 69499

 - Transactions and conn pooling Apparently conn pooling maintains separate pools for the same connstring, depending on whther the instance has a transaction opened on it. The actual connection supplied depends on the "transaction context" -Does this only work for COM+ transactions? There seems to be no way of opening a new conn under an existing sqlTransaction object? -to allow a trans to span several objects and methods in the middle tier, I might open a global trans object and a global conn, and use them for methods I want to be part of the transaction(disposing when the trans is complete). All this would happen within one high-level method. Has this any downside, other than maintaining state and an open conn for a while longer? Tag: Active Directory Related Question. Tag: 69492

 - HLP: Using 2 Filters for a Query in a FILL I'm having difficulties in Filtering an OleDbDataAdaptor... Currently I've a single query for it such as the following: SELECT Employee, ID, Period_End_Date, Units, [Date] FROM tblTimeEntry WHERE (Employee LIKE ? + '%') Simple enough. And I can do my FILL via something like: Dim strUserID As String ' User Name Filter strUserID = UCase("feu001") daTimberline.SelectCommand.Parameters(0).Value = strUserID daTimberline.Fill(dsTimberline.tblTimeEntry) What I'd like to know is HOW to do a query with TWO (2) queries. Say Employee (user Name - as above) _and_ something else (say Date)? In the past I've had one reply. Although he tried to tell me. His answer wasn't too clear to me (I've only been dealing with DB's for less than 2 weeks now). So the answer kind of went over my head :( So any info and some more detailed info would be appreciated. Basically... I've an Access file that has User info and Dates and Time Sheet entry stuff. What I want to do is to do a FILL (or what ever I need to do) using the Users NAME (employee) and a DATE. Right now I can do one or the other... not both. As long as I get the records for that User and Time periods (can be 1 to 50 +/- record sets). I'd rather work with this number rather than hundreds of plain User record sets (which is what I get with just User name filtering). Thanks for any help in advance.

 - Impersonation and conn pooling In the .NET data access arch guide (patterns and practices) its says Avoid impersonation in the middle tier because it negates conn pooling. Why? If you impersonate a limited number of windows users which are actually roles(depending on the actual user of each instance of the app), conns for the same user should be pooled, shouldn't they? The doc does go on to say something like this but I'm not sure what its trying to say. I would be grateful if someone could clarify this for me. Tag: Active Directory Related Question. Tag: 69489

 - looping through a dataview I am trying to loop through a dataview to collect rows after they have been sorted, and insert them into a new table. Here is a code snippet: DataView dv = (view of table of existing dataset) DataTable dt = new DataTable(); foreach (DataRowView drv in dv) { dt.Rows.Add(drv.Row); } This generates the error that the row belongs to another table. Any suggestions on how to change this to make it work? Thanks, David Tag: Active Directory Related Question. Tag: 69486

 - Problem with commandtexts Hi Every time I change the structure of a table, I need to adjust the command texts for select, insert, update & delete commands. Is there a way that an app, on load time, can automatically take a table name and create the necessary datatable, dataadapter and more importantly the corresponding commandtexts from it? Thanks Regards Tag: Active Directory Related Question. Tag: 69465

Hi,

I like to know if there is any way we can use SQL Query syntax for

using ADO? I don't know.

You could try using WMI with WSH, try asking here:
microsoft.public.windows.wsh

Yes, you can use the ADO provider for AD to get some values - read up
in MSDN on how to do it in detail:
