I am trying to add an xml file from a resx file to a dataset. I have had succes with this so far,
but for some reason i have a form where it doesn't work and i have no idea why.
The code looks like this:
ds.Tables.Add("list") 'ds = dataset global public variable
ds.Tables("list").Columns.Add("FileName")
ds.Tables("list").Columns.Add("EntityType")
[Code]....
How do I do this for a different dataset? I'm trying to rule out database problems so I made another one and added it, but now I need a table adapter for this one instead of the old database because it keeps giving me an error. I don't see any place to add them and I'm getting extremely angry at these databases.
View 1 RepliesIn a project, I have a dataset with two table adapters. Without warning while I was modifying one of them in design mode, I received this error. I have typed the contents of the dialog box exactly as they appear - so no additional information was given, and the error code was "-1".
View 2 RepliesI use a dbDataAdapter to populate a DataTable from an unlinked oracle database.I have a dbDataAdapter that I want to insert rows into an SQL Server table using SQLCommandBuilder.I have been trying all day to update the DataTable that references the SQL Server table with the data from the Oracle DataTable so that I can insert the rows.
View 2 RepliesI have a large form that is set up from master-detail datasets in Visual Studio 2008.I havene master table with a large amount of detail tables. Several of the detail tables also have detail tables linked.Now I need to add a master table that sits on top of my existing master table making it a detail table.
View 7 RepliesI have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable"
Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!
How can I update local dataset with mysql database without making duplicates. Assuming I set some column in mysql as primary key, which has unique string.
adapter.fill will just add duplicates, but adapter.clear before that is not an option.
So I want to update if the key column is the same with mysql data and if there is option for ignore adding new row.
I have some concern about designing Datasets. I was told that it would be good to have a dataset for each table for maintenance purpose. Because frequent change in database tables is expected, having one dataset including every tables would be pain to make the corresponding change in the application.
Q. is it good approach to have a dataset for each table ( I would end up having 30~40 datasets for each db table using Stored procedure) ?
I have a separate project for commonly used datasets. each project include "dataset project" as a reference, and use it by including needed dataset into Forms, classes, etc.
Q. Does this approach makes the whole system to be slower? If I have a set of datasets as a separate project, it would be beneficial, since It will be easier to make a change (I only need to make modification in one place)
I have a dataset (WW1Dataset) with one data table(WW1).(database used in an access database) I'm trying to filter the dataset e.g a user wants to filter by a chosen surname (SurnameTextBox.text) so the datset is filtered to display only those records wherethe surname column in the dataset matches SurnameTextBox.text.
View 1 RepliesI have two table called
1.Register product table
2.Sell product table
Register product table consist of (Product Id (txtProdId.text) and Product Name(txtProdName.text)) NB. All are textboxes Sell product table consist of (Product Name(cboProdName.text) and ProdPrice (txtProdCost.text)). NB. ProductName over here is a combobox.
When someone saves record in the Register product table, items should be added into the combobox into Sell product table.

I have a dataset that is being populated from a text file.
OrderNumber,Name,Model,Cost
123,john doe,product1,20.99
123,john doe,product2,10.75
There can be multiple of the same order number. In the dataset, I want to have a column "line number" and I want to put in it the value of the linenumber (in this case 1 and 2) per order. In sql , I was able to accomplish this by inserting rownumber() and grouping by order number. Can this be done in .net?
I have a piece of code that works for adding multiple rows to a dataset but I think that it is a lot of code and thought maybe someone may know a better way of doing it. I need to add rows to the dataset based on the selection of a combo box. ie if the user selects 15 the the program adds 15 rows to the dataset.
Case cboQty.SelectedItem = 3
Try
Dim dr As DataRow

I'm trying to add a new record in the DataSet in the master table. I'm not including a value in the unique ID field because it is added automatically by the server. At the moment I add second new row it throw me an error �Column 'ContactID' is constrained to be unique. Value '' is already present.� Do I need to set value of id column manually? How?
da.Fill(ds, "tblContactsProfil")

I am using VB.NET 2008 Express. I had a project with a mdi parent and several child forms. On the child forms, I created a datagridview by dragging the necessary table from the dataset(s) from the data sources window.
Main form - PastorBase
Child form - IllustrationList
When I try to debug it, I run into several errors from the code of the IllustrationList.Designer.vb file in this section [Code] However, the moment I make any change to the control by modifying properties or simply resizing it on the form, my change in this code is lost. So I am repeatedly having to change these lines (there are about five per child form). I am uncertain of what I am doing wrong. Should the dataset, etc. be added to the parent form and then called from the child form? Is there some setting I need to change somewhere?
I add a row to the DataSet using the following code:
Dim NewRow as DataRow
NewRow = gds.Tables("TitleDataSet").NewRow
NewRow("Title") = txtTitle.Text
NewRow("Local_number") = nubLocalnumber.Value
NewRow("Number_suffix") = txtNumberSuffix.Text
etc.
This code executes without errors but the bound DataGridView remains unchanged (without including the new row). Obviously I am doing something wrong or I am omitting a vital command. What do I need to do in order to make the new row appear in the DataGridView? I did not choose to bind the DataGridView directly to the database table because the database is selected by the user at execution time. Instead I bound the DataGridView to the DataSet. I included the command:L
dgvTitle.AllowUserToAddrows = True
but that did not have any effect.
Solved. Was missing the final command:L
gds.Tables("TitleDataSet").Rows.Add(NewRow)
i am making a table through vb.net code (htmltablecell, htmltablerow..) no this table populates with an sql query and works perfectly. but inside this table in one tablecell, i need to add a dropdownlist which shall require a completely differernt query and shall run on its own on each row. so the code is as follows
Sql = "..."
rd = ExecuteReader(SqlCnn, Sql)
Dim newcounter As Integer = 0
While rd.Read()
[code]....
the ??? in the code is where the dropdownlist shall get populated each time with its own datareader and while loop and query.
I have a question about using writeXml. When I use this method, it writes to the specified xml file like this:
<safety><Incident>
<Name>Jason</Name>
<AGE>23</AGE>
</Incident>
<Incident>
<Name>Frank</Name>
<AGE>25</AGE>
</Incident></safety>
But, I would like to add these nodes to a parent node, i.e.:
<safety><SomeNode><Incident>
<Name>Jason</Name>
<AGE>23</AGE>
</Incident>
<Incident>
<Name>Frank</Name>
<AGE>25</AGE>
</Incident></someNode></safety>
I am creating the xml by first creating a dataset (connects to an SQL db and runs a query, filling the dataset) and using ds.WriteXML(myPath)
I want to use dataset for sql server for adding/modifying/deleting data from sql server.
View 8 RepliesI am trying to use a data set to replace some objects i have currently got but wich are getting rather complicated. I have created my self a Data Set, currently simplified but am just learning ATM, I have normalised it as per basic understanding of databases.
3 tables
A Parts Table with 2 columns, Serial Number as the primary key and Data Inspected
A Feature Table with 2 coloumns, Feature Name as the primary key and Nominal
Data Table with Part Serial Number, Feature Name, Actual and a KeyColumn which is self incrementing read only.
Ultimately the Parts Table and Feature Table will have a lot more meta data that I will want to sort/filter. I would like a Data Grid Veiw or equivalent in WPF to show a table of all the data for all the parts, so features along one axis and parts along the other. Ultimately I would like to be able to sort/filter on both axis using different bits of meta data. I am aware of LINQ and DataVeiws, have had a play though not good at either, so far have only managed to get one column of data, so either all the data for one part or all the data for one feature.
I'm also aware of the Entity Framework though have no idea how to use it. So my question is, do I need to extract the table one column at a time? seems a bit inelegant, or is there a query or View I can set up to do this? or am I using completely the wrong tool? I know this might work in a fully fledged database but cant install/assess one on the machines to be used I need to keep it contained to the .net executable. If I need to do it as a loop am I right in assuming LINQ would be a better choice to put in a for loop?
I am developing a s/w. I am trying to update data in table. While I save the data, it will update into table. I have a gridview which binds table data through dataset. While I update the changes it is not reflecting in the grid view.

Dataset table not updating The reason why everything ends in 1, is because I have another instance running with similar names... so disregard that.
I am using VB.NET 2008 and I want to delete an unused table from the dataset. When I do this I get error messages which seem to originate in the Table Adater Manager on the various forms. The only way I can figure out to correct this is to delete the table from the code after deleting it from the dataset designer. But it says that you shouldn't do this.
View 5 RepliesI just want to ask. Using getChanges method in vb.net only get the changes on the dataset not on the table in database?for example I fill a dataset from a table in database.So there is a table in my dataset. There has been a changed in my table in database for example an added row.So there is no way in my dataset to determine this change because it has filled the original data.How can I determine the changes in my database table?
