I had a datagridview which connect to oracle database. I want to filter one of the column of the datagridview.
Then the filter value will show it in the combobox.
Any suggestion to filter it and show at combobox?
I have a datagridview and a bindingsource. The first column is a comboboxcolumn which is bound to a table field and then the rest of the items are populated from another datatable. What I have on my other forms is a textbox called txtfilter and on the textchanged event I have this
Me.ProductBindingSource.Filter = "BatchNo LIKE '" & txtFilter.Text & "*'" that works great. Now I want to filter the combobox columns just like this.
Hpw can I pass multiple values from same column in a query? I am using vb.net and sql server database.

How would I implement a simple low pass filter in VB.NET? I have a byte array of 8-bit sound values sampled at 44.1 KHz and I would like to apply a crude and simple low pass filter that starts to roll off around 2.5 KHz. Nothing fancy - I'm not expecting lots of dBs per octave, just something to slightly reduce unwanted HF components. When I Google this all I seem to find are complex FFTs and other functions derived from electronics design packages that are way beyond my math to have any chance of adapting them for VB.NET.
I have tried some very crude averaging: take sample 0 and sample 2, average them and put the result in sample 1. It sort of works but is probably a bit too crude.

I have quite a complicated database with a lot of relations and I need to make form that gets data from all kinds of tables and calculate prices etc... Another important thing is, when I open/load a report in my application, I want to be able to filter it using the Primary key. I don't want all records in my database to be shown. I know for sure this can be done but I don't know how.
View 2 RepliesI want to query an access database with variable data defined by the user. The "Search" criteria would be in a textbox. I made a query like
SELECT askID, Question
FROM chita
WHERE (askID LIKE 'Textbox10.text%')
and referring to this query as
Form1.ChitaTableAdapter.searchrec(Form1.ChitaDataSet1.chita)But id does not take the value of the textbox, instead it takes the Textbox10.text as a value. Is it possible to refer to it like this, or should I Linq?

Kinda new to working with wpf apps (and vb.net). Looking for a way to filter a datagrid using a combobox (to select the field that the user wishes to search) textbox (to input search terms for specific records). The datagrid loads fine as does the combo containing the fields, however my filter simply does not work.
Code for loading data (works fine)
Dim obj = Me._dataManager.Collections.ReturnCollectionByID(tableSelectionCombo.SelectedItem.TableID)
Me.DataGrid.ItemsSource = obj
obj.Load(New DataManagementDataRequest(Nothing, Nothing))
Code for filtering (not working)
If Me.searchTxt.Text IsNot Nothing Then
obj.filter = selectFieldCombo.SelectedItem.ToString Like searchTxt.Text.ToString
Else
obj.filter = ""
End If
I have started a form application using visual studio 2010 express, vb programming. I'm using Access as my database.My goal is to have ComboBox1 display a ProjectID and ComboBox2 display a TestNumber. Once the Test Number is selected I want my textboxes in the form to display fields from the row that the selected Test Number is in.I have 2 tables set up right now "Projects" and "TestData". The "Projects" table has a [ProjectID] field, the remaining fields are just misc. project data. The "TestData" table also has the [ProjectID] field, and then the [TestNumber] field, then the remaining fields are misc. data.
Filling [ProjectID] in textbox1 is easy, in the properties I select DataSource from the Projects table, display [ProjectID] field. Where I'm having troubles is ComboBox2 displaying the TestNumber from the other "TestData" table. If I select that field, it fills the ComboBox with EVERY TestNumber there is. So for Project 1 there is a test 1... over 500 projects, that combobox lists 500 Test 1's, no way to tell what project it belongs to...How do I make ComboBox2 only display Test Numbers that pertain to the Project number selected in ComboBox1?Using this code I can get it to work:
Dim ProjectNo, SQLString As String
Dim dtTableData As New DataTable()
Dim dbDataAdapter As OleDbDataAdapter
[code]....
I also imported system.data.oledb Problem with this code is it will only filter data in ComboBox 2 but when you make your selection from ComboBox2 it won't activate the row so none of my databinding textboxes fill anymore. Before the code/query is ran it fills up the textboxes perfectly after every selection I just have no idea what project that report number belongs to because the whole field is displayed in the dropdown. I can fill the form with ComboBoxes and they display the corresponding row data because I use a "datasource" instead of textbox "databindings" but I don't want to use 20 comboboxes as my entry form...

Where do I get all the functions that can be used in Query Builder?
i was wondering if there was something i can use in VB which will let me have some fields in the DGV query to automatically have the format of 0.0000? There are some fields in that query which require this format. The Crystal Reports that accesses it gives incorrect info without this format type.
View 6 Repliesi have this win form app that performs a database search of customer information. I have a datagridview, a binding navigator and a fill/addquery toolstrip with a toolstrip button and a textbox.Here is my query, i want to find all customer names like what i enter in the textbox
SELECT ACCOUNT_NUMBER, COMPANY_NAME, COMPANY_ADDRESS, BILLING_ADDRESS, CITY, STATE, ZIP, COUNTRY, PHONE FROM tblCustomerInfo
WHERE (COMPANY_NAME LIKE @COMPANY_NAME + N'%')
i am using sql client with a datagrid and i already bind the data to the grid as a dataset automatically so i did not manually code the connection, cmd, dataset ect here is the find button code that recieves the customer info according to the sql query
Private Sub FillByToolStripButton_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FillByToolStripButton.Click
Try
Me.TblCustomerInformationTableAdapter.FillBy(Me.CoCustomerAccountInformationDataSet.tblCustomerInformation, COMPANY_NAMEToolStripTextBox.Text)
[code]....
COMPANY_NAMEToolStripTextBox.Text is where the the Customer Name will be entered... I originally called it txtName.Text but still even when i changed and did everything through the query builder I get nothing when i run the query.
It seems like the query builder in vb only allow 1 table to use the INSERT statement, so are there any way add more than 1?

In Access, when you build a new query, you can add tables to the view, which is then represented by individual windows that are somehow embedded/constrained to the upper portion of the query designer. I know then typically, windows are free floating anywhere on the screen, but somehow they manage to keep it confined to a certain container area. It also appears that the windows never get a real "focus" as the title bar is always a faded shade of blue, yet, you can still click on them and move them around.
