    - Quick data retrieval Using 'old' ado and VB6 I could use following two lines to quickly retrieve data from a MSSQL server into a fire hose cursor: Dim rst As ADODB.Recordset Set rst = cnn.Execute("{call a_stored_procedure}") Can I do something similarly in ADO.NET using VB.NET or C# to get results from a stored procedure into a data reader (using as little code as possible)?

    - Checking for changes to database Has anyone got code for checking if the database row being viewed has changed since it was delivered to the browser? ie before the UPDATE is run? I'd imagine it would work something like this: First page request (doing the select): ====================================== select row from table store row in session bind controls to row values (dataset or whatever) end Wait for user to do edit, and press submit. Page postback: ============== begin transaction select same row from database again compare with row held in session if they match, apply changes from user postback if they don't, inform user underlying data has changed, and request confirmation (showing 'befores' and 'afters') commit end Tag: I need some help with this code....

    - Writing null values using WriteXML() I've got a dataset that contains fields of different types, including dates. I need to convert the dataset to a string and to do that i use WriteXML method. The only problem is that after the conversion all the null values are missing from the string. With string fields there is no problem cause I put "" in them but with dates it IS a problem. So how can a date field be saved when it contains null value? Tag: I need some help with this code.... Tag: 72369

    - Error message I've got a VB.NET program that collects info from an Access database. I'm trying to use the following select command to select all the information from the "Families" table and store it in a dataset, plus join the Surname and FirstName fields to create a new field, FamilyName: selFamilies.CommandText = "SELECT Families.*, (Families.Surname + ', ' + Families.FirstName) AS FamilyName FROM Families ORDER BY Surname, FirstName" This has been working perfectly a number of times until recently, and now when I try to run the program, it stops on this line: adpFamilies.Fill(datSPARK, "Families") and gives me this error message: "An unhandled exception of type 'System.InvalidOperationException' occurred in system.data.dll Additional information: System.InvalidOperationException: Invalid attempt to NextResult when reader is closed. at System.Data.OleDb.OleDbDataReader.NextResult() at System.Data.Common.DbDataAdapter.FillNextResult(IDataReader dataReader) at System.Data.Common.DbDataAdapter.FillFromReader(Object data, String srcTable, IDataReader dataReader, Int32 startRecord, Int32 maxRecords, DataColumn parentChapterColumn, Object parentChapterValue) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, String srcTable, IDataReader dataReader, Int32 startRecord, Int32 maxRecords) at System.Data.Common.DbDataAdapter.Fill(Object data, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, String srcTable) at SPARK.frmFamilyInfo.GetFamilies() in C:\Documents and Settings\Owner\My Documents\Visual Studio Projects\SPARK\Info Boxes\Family Information.vb:line 1511" I tried setting the CommandText properties in the form design with my original select query, then right-clicked the data adapter and went to Preview Data. When I fill the dataset with the selFamilies query, it returns the correct information. However, when I run the program without readjusting the query in code, I still encounter the error message. It is obviously gathering the correct data from the database; is it trying to do something else with the dataset? I would really appreciate any help anyone can give me.

    - counting records Probably an easy question, but how do I count the number of records in a dataset when there are no bindings. I was using me.bindingcontext(dsName1).count, but it is always returning 1 when I know for a fact that the test data has three records. I am using dsName1.tables(0).newrow to add the new row; the user sets the information and then saves this row back to the dataset and then the data adapter is updated. What I want to do on form load is to return the number of records currently in the dataset. Thanks for the information. Brad Tag: I need some help with this code.... Tag: 72356

    - Generel Questions Hello, I think I'm experienced at an average with .NET, but I'm going to plan a database application (Isolated application with low-level synchronisation capabilities between two clients; mainly for use on notebooks to collect time and operation data), which later should be shipped with the database engine, I'll use. Since the amount of data is not very extensive, I decided to go for the jet engine, to keep the deployment efforts and possible royalties as low as possible later on. I'm not that experienced with ADO.NET, so I played a little with the ADO.NET capabilities, and was impressed especially with the strong typed datasets. But I also noticed something which in my opinion could seem to be a weakness, since my application has to deal with null-values in the database a lot (which, in my case, will often appear in the front end, and have to be displayed with interstate checkboxes, empty textboxes or specially marked table cells). So my questions are: Would it make sense to create a general ValueType (something like the old vb-variant) and a correlating user control, which would be able to handle that variant (and therefore DBNulls) without additional case testing (If DBNull then blablabla else blablabla)? And: Is it the right decision to use the access-engine for my purposes? Any source from the net about that topic I'd really appreciate! Thanks for giving me your opinions!

    - BeginEdit EndEdit slow when updating a large number of cells in temporary column I have a Windows Forms DataGrid bound to a DataView of a DataSet. I need to sort the rows in the DataGrid based off of a custom functions return value. To do this loop through all of the rows in the DataView and pass the required information from each row to my custom function and then I write the value returned by the function to an additional column which I added to the DataView. I can then and sort based off the the values in that column. The problem is that updating a whole column of cells in a DataView it is extremely slow (over 10,000 records). I noticed that if I call BeginEdit on each row before I change each of the cells it updates all of the values fairly quickly. The calculated values are displated in the DataGrid but when sorting it still uses the previous values (Because EndEdit was never called). The values I calcuate and add to this additional column do not need to be updated in the database, they are only used to sort the data for viewing purposes. Is there a faster or better way to do this? Is there a way to sort a column using the Proposed values before EndEdit is called? Is there some way to add a column to a DataView that can be freely written to without having the overhead of calling EndEdit? Thanks, Kurt Tag: I need some help with this code.... Tag: 72353

    - Using DataSet from VB6 Hi I have an application in VB6 that works only locally but i would like to make it able to save, update and get records from a Database. The problem is that i want to use the .NET technology and realize a disconnected scenario. I Know how implement this type of application in .NET. I would like to know how to use a Dataset from VB6. The scenario is this: I download some record from a Database using a Web Service and then populate a DataSet that i want to read from VB6 Then, in the VB6 application , I use these records and change the values or create other records. I want so save these records in the Dataset and then, in a second moment, save all added and/or updated records to the Database using a WebService. The problem is how to store new value from the VB6 application to a .NET DataSet and then using this DataSet to consume the WebService. Thanks!! Tag: I need some help with this code.... Tag: 72325

In asppage.asp code will be like: <form action="aspprocess.asp" method="POST"> GUI CODE </form> When the user clicks the submit button on asppage.asp, it will invoke aspprocess.asp page aspprocess.asp code can get the user input from asppage.asp by doing: Request.Form("Control_ID") In ASP.NET, if I want to achieve the same goal: if I have aspxpage.aspx for GUI and aspxprocess.aspx for process requests from database In aspxpage.aspx code will be like: <form id="Form1" method="post" action="aspxprocess.aspx" runat="server"> GUI CODE </form> However, when the user clicks the submit button on aspxpage.aspx, it didn't invoke aspxpage.aspx page at all, unless I do the the following: Private Sub Submit1_ServerClick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Submit1.ServerClick Response.Redirect("aspxprocess.aspx") End Sub But even now I am in aspxprocess.aspx page, how can I get the user input from aspxpage.aspx??

    - Add Columns to a datagrid from a 2nd datatable (unbound) I have 2 data sources (1 - DB, 2 - unbound table). I want to be able to display all of the columns in a datagrid on a form. I can't seem to make the unbound table show up when I run the program. The data table for the 2nd unbound table starts with nothing in it but has 5 columns defined. I would like to see all of the columns from the DB and unbound table when the form loads instead I just get the DB column names and data from the DB. My data sources seem to be working correctly but I'm not able to get the DataGrid to work correctly. I use a button on the form to start/stop the async. data source and it does work, but I can't get the data to show up in the DataGrid. I have tried MissingMappingAction, MissingSchemaAction and doing a merge with the 2nd datatable. I decided to recode it and use an add but that isn't working either? What should I be doing to make to get the results I need. c# code for this.... da = new OleDbDataAdapter(strSQL, oCon); ds = new DataSet(); oCon.Open(); dt = new DataTable("unbound"); dc = new DataColumn(); // Last dc.AutoIncrement = false; dc.Caption = "Last"; dc.ReadOnly = false; dc.Unique = false; dt.Columns.Add("Last", typeof(Double)); // Bid dc = new DataColumn(); dc.AutoIncrement = false; dc.Caption = "Bid"; dc.ReadOnly = false; dc.Unique = false; dt.Columns.Add("Bid", typeof(Double)); // Ask dc = new DataColumn(); dc.AutoIncrement = false; dc.Caption = "Ask"; dc.ReadOnly = false; dc.Unique = false; dt.Columns.Add("Ask", typeof(Double)); // Volume dc = new DataColumn(); dc.AutoIncrement = false; dc.Caption = "Volume"; dc.ReadOnly = false; dc.Unique = false; dt.Columns.Add("Volume", typeof(Int32)); // Momentum dc = new DataColumn(); dc.AutoIncrement = false; dc.Caption = "Momentum"; dc.ReadOnly = false; dc.Unique = false; dt.Columns.Add("Momentum", typeof(Int32)); ds.Tables.Add(dt); //da.MissingMappingAction = MissingMappingAction.Ignore; //da.MissingSchemaAction = MissingSchemaAction.Ignore; numrows = da.Fill(ds); //ds.Merge(dt,false,System.Data.MissingSchemaAction.Add); Thanks....

    - Simple question -Dataset New to .net .... I now have a dataset with one table in it name "MYTABLE" 1.) How do I read the value in the 3rd row, 2nd column of the current rowstate? myVal = ????.value 2.) How do I replace that value with a new value? ????.value = myNewValue **** Just some rambling... I've read six books, and spent hours looking through the SDK help, looking through samples and another hour looking at the quick watch to try to figure this SIMPLE thing out. There are REAMS and REAMS of information, but a simple thing like this aught to be the FIRST thing that pops up in the help about a dataset. I now know how to XML it, REMOTE it, BIND it, TWIRL it, and SWIRL it (oh ya), but coming from another OO language, I just want to know how to READ and WRITE it! If I sound frustrated, I am. Is there a easy way to find things in the help system? For example, coming from other languages, you pretty well know some of the basic things you want to do, i.e format a string to a date, or find out if a file exist, read and write to a field, etc. When you search the SDK help, with something like "FORMAT STRING" you get a gazzillion things back, and little to do with what you are looking for. If you know the syntax... i.e. String.Format and type that in, then you find what you are looking for, but I don't know the syntax, that's why I'm looking in the help sys.

    - DataView.Find (SQL Server 2000) I need to be able to sort/search a datatable for 2 columns, both of type integer. Is this possible? Dim dv As New DataView(MyDataTable,...) Dim dr As DataRowView Dim iIndex As Integer Dim objSearch(1) As Object dv.Sort = ("Column1, Column2 ASC") objSearch(0) = 5 'Locate 5 in column 1 objSearch(1) = 6 'Locate 6 in column 2 iIndex = dv.Find(objSearch) Will this find rows in my view where Column1 = 5 AND Column2 = 6? Or will it find rows where Column1 = 5 or 6 AND rows where Column2 = 5 or 6? As an alternative, I could apply a filter upon the DataView when enstantiating it. However, wouldn't this be less efficient/concise than DataView.Find? -bgsd Tag: I need some help with this code.... Tag: 72242

    - 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: I need some help with this code....

    - 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: I need some help with this code.... Tag: 72192

    - use crystal report in ASP.NET datagrid search result page I am new to crystal report. I have ASP.NET pages that show the search result. Since the search result is represented by datagrid, it will be nice to put a button on that page, and allows the user to export the result to crystal report. Here's what I have done so far, and I dont know what to do next. 1) Add CrystalReportViewer web control to the search result page. 2) In my ASP.NET application, I added a new item crystal report (.rpt) In my case, can the crystal report just get the result from datagrid.

    - 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: I need some help with this code.... 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: I need some help with this code.... 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: I need some help with this code.... Tag: 72157

Hi,

Can someone please look at this code and tell me why I get an exception
error on the last line:

For aa = 0 To ds.Tables(0).Columns.Count - 1
dbColumn = New SQLDMO.Column
dbColumn.Name = "'" & ds.Tables(0).Columns(aa).Caption & "'" 'ds is
the dataset
dbColumn.Datatype = "VARCHAR(1000)"
dbColumn.AllowNulls = False
dbTable.Columns.Add(dbColumn)
pgBar.Value += 1 'progressbar
Next
sqlServer.Databases.Item("sitelist").Tables.Add(dbTable) 'On this line
I get an exception error.

The database is created but the table won't.

The exception error tells me only how the column definition should be, and
as far as I know I have it right...

thanks,
Eric

Found it!

it was the VARCHAR(1000) it should have been VARCHAR en the length of the
column should be set on a number
