Add Additional Rows To Dataset?
Jan 26, 2011
I have a parent/child relation I am trying to create fow 2 datasets.The parent ds consusts of a range of PO Header information
After I fill this dataset I loop through it getting the PO number. I then take that value and execute another sql statement on the DETAIL file and fill a dataset(dtlDS) for EACH row in the parent. How do I add to this dtlDS for each row? I am getting no CHILD data in the merge. Should I be filling to a datatable and do an add.row and THEN dump into the dtlDS?

I'm am very new to Vb.net, I have coded in VBA.I have created a form that will open Microsoft Excel, add header text to the columns, and insert the text from a few of the controls located on my form ("not finished adding controls") when I click the Submit button.
My problem is that when I enter different data into those controls and click the submit button again, I get a new Excel Workbook with the new data.I need the new data the be submitted to the .Activecell.Offset(1,0) of the already open workbook.Ultimate Goal of Submit button is to open new Excel workbook, Enter multiple rows of data via Visual Basic Form.

I am using vb.net 2010. I have a datagridview whose data source is a data table. I dynamically add rows to the data table.
[Code]...
After adding the new row, m_table is correct. However, DVGCusClient not only adds this row, but also adds two additional blank rows at the bottom. I have no idea where these two blank rows come from. Why I use above code is as follows: Use a data grid view to display data. When a user clicks a row, another form is opened which allows user to search/input some data.When the user closes the form, all data is saved to a data table and shown on the data grid view.

I have a model that returns a dataset to a view and builds a list. The crazy thing is that I have tested this code with IE, Safari on Mac and Windows, Chrome and Opera and all return data. However, on the iPad or iPhone, zero rows are returned from the dataset object. It seems that the model is in fact passing the dataset to the view. I am using jquerymobile to render the view for the iOS devices and have taken that out of the mix to test and it still doesn't work.

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 am new to vb.net and I am trying to query a database and print out the records in the row to the console window. I got it to work, but I have a feeling that there is a more concise way to do this. One thing that I am sure is wrong is that I had to convert the dataset to a datatable to be able to retrieve the values. Is that correct? Could you take a look at the code below (especially the for loop) and let me know what I can improve upon?

My Application uses For...Next loops to read a spreadsheet into a DataSet and then display information from it based on the results of search conditions (search term and a date range).I'm having a problem with the data where, if I run a search that should return the first 400 rows in the spreadsheet, I'm only getting around 200 results. I know the search should return the 400 rows because I checked it in the spreadsheet before running the search.I think my problem might be caused by my date comparisons. I think the problem might be that I'm comparing String valueHere's my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If ListBox1.Items.Count <> 0 Then : ListBox1.Items.Clear() : End If

I have a form with the datagridweiw object. I have connected it to the datasource and it displays the data fine. I also have set the persissions for editing. I am assuming i need a button for accepting changes to table and a button to cancel. My use for the form is to add or delete rows of data and save the changes. The database and application are both in visual basic and sql server express both 2008.

I have used VB6 for all kinds of database programming. Now I am fairly new to the vb.net. How do we read the records (rows) from a dataset and manipulate data? I want to populate a combobox or a datagrid with a recordset (in VB6 language). What is the .net equivalent of ado dataset, and how do I use it. I have tried several ways using dataadapters and dataset, etc.

I am trying to retrieve row data from a table in a dataset (dataset name is PatientsDataSet and table name is tblfacilitiesnames).
I am using VB 2008 but the code I entered is from a VB2005 sample so something must have changed in the format.
I am already connected to the database since it opens the connection when the program is run.
Here is the code:
Dim Counter As Integer
Dim Str1 As String
Dim FacRow As PatientsDataSet.tblFacilitiesNamesRow

I have a question similar to this one, but reading the (accepted) answer didn't give me much insight, so I'm hoping to state it more clearly and get a clearer response back.
I'm attempting to insert a data row into a table. I'm using TableAdapter's custom "insert nonQuery" that I wrote (it works, I tested) to accept some parameters. I'm fairly new to this business of communication with a database via .NET and what I'm doing is probably wrong by design. My questions are why is it wrong and what's the right way to do it? Both are equally important, IMO.[code]...

I have created a strongly typed dataset in the VS 2005 Dataset Designer. There are two tables that relates to each other in a one to many relationship: Claim and ClaimDetail. The designer automatically creates a function GetClaimDetailRows which returns all ClaimDetailRows for a ClaimRow. Why is this Array's length always 0? Because ClaimDetail contains more than 40 Million rows, i did'nt fill it before i call GetClaimDetailRows but had configured it's selectcommand that it takes a parameter idData to fill only the related records. But that seems not to work because the ClaimDetail-Datatable is empty.
The automatically generated function in the ClaimRow-Class which returns all related ClaimDetailRows:
Public Function GetClaimDetailRows() As ClaimDetailRow()
If (Me.Table.ChildRelations("Claim_ClaimDetail") Is Nothing) Then
Return New ClaimDetailRow(-1) {}
Else
Return CType(MyBase.GetChildRows(Me.Table.ChildRelations("Claim_ClaimDetail")),ClaimDetailRow())
End If
End Function
When debugging I see that it jumps into the else block but returns 0 rows. Do I have to fill the Claimdetail-Datatable first(ClearBeforeFill=True) for each Claim? But then I don't need to use this function anymore. I now fill the Datatable(ClearBeforeFill=True)before i call the Child-function and it works. But I don't understand why it could not throw an exception(optionally) when I try to acess a child-relation without having that datatable being filled(at least with 0 rows). Instead of that it returns 0 rows what can be correct or incorrect and is difficult to detect.

I have a table in a databases that contains 12 rows. I am loading a runtime dataset with that table. The result are displayed on 2 different controls. The first one is a DataRepeater and the second one is a DataGridView. The DataGridView displays all 12 rows just fine.
The DataRepeater does not. Some of the 12 rows will be blank and some will have the data. Sometimes I won't see any data until I completely cycle the scroll bar to the end and then back and still some of the 12 rows will be blank.

I have a dataset that I search using the
dataset.tables("table").Select("WHERE clause")
method to query. I then use a datarepeater to display the results. Is there a way to programatically tell if no results are returned? I'm aware of the Dataset.tables.Rows.count, but can this be done after the select method?

I have a dataset column that I am keeping comments in. If the row has no comment in it(defualt string value is "", not NULL), I don't want it to show up on my report. How can I fill only the datarows that have text in them and not the ones that are empty. I've tried to filter the columns results by Not Nothing, but everything shows up. I'm guessing because it's actually not NULL since the string is "". How can I filter these results correctly?
