I have a list of Active Directory entries (computer names) as a Collection data type. How can I add the computer entries and the pertinent columns to the DataGrid control on my WinForm? I have borrowed this code from some web site to add the list of computer to the pcList which is a Collection type.
pcList.Add(dirSearchResults.GetDirectoryEntry().Name.ToString())

I have a custom collection which is derived from a base class implementing IEnumerable and IEnumerator, this collection is populated with custom objects.I'm trying to set the datasource on a ComboBox on a WinForm to use the above collection - but when the code is run the ComboBox is always empty.
The code I was using was this:
Private Sub ViewSources_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

Here's the scenario, winforms application, monitoring via Task Manager Processes Tab.On initial launch spins up to ~61,000K (initial data grid and data loads)If I minimize the application, not touching or doing anything the Mem usage drops to 1,380K.When I restore the application is spins back up to only 5.8K
So my question is, does the minimize send some internal message to clean up resources since the application in question is not in focus?The first app I noticed this in happens to be VB.NET, but I've observed the same behavior in my main C# winform applications.

In code behind i selected the datagrid and double click event. when i double click on teh grid in debug mode, it never fires off the event(i put a breakpoint in). I've tried several other events and none of them are firing.

I am using Visual Basic in Visual Studio Express 2008. I am creating a form that works with an Access database which has five tables, though for purposes of my problem I will only mention two of the tables: Customer and Project.
The Customer table contains basic customer info, with a unique ID auto-number. The Project table describes relationships between two customers. There is a Primary ID number and a Secondary ID number, both of which correspond to an ID number from the Customer table. Any given ID number can exist as a Primary or Secondary ID, so if "Bob's Company" ID is 1, and "Fred's Company" ID is 2, there can be two projects, one having "Bob's Company" as Primary and "Fred's Company" as Secondary, and the other vice versa.
The user navigates through the Customer table by means of a combo box. They choose one customer name from the box, which populates a label with that customer's ID number. I have a View Projects button with the intent that once the user chooses the company, they can click View Projects and a DataGrid will appear which contains only the records from the Project table in which this specific Customer number appears (either as Primary or Secondary). So basically, with all that explanation, I'm trying to figure out how to get the View Projects button to take the CustomerIDLabel.Text and use that to populate the DataGrid.[code]...
I am developing a Windows application in Visual Studio 2005, V2.0 using VB.NET.I am coding part of an Emergency Response Information System. On my form, I have two combo boxes (cboBaseStationID and cboPriority). I am trying to populate the datagrid with records from my database based on what is selected in both comboboxes. For the first combobox, the user selects a name so the datagrid must only show records with that name. For the second combobox, this is a little more complicated. There are four emergency priorities in the combobox that the user can choose - 1, 2, 3, 4. In the database, there are different response teams (to be dispatched to these emergencies) and each response team has a grade of either 1, 2 or 3. So a grade 1 team can respond to emergency priorities of 1 and 2.A grade 2 team can respond to emergency priorities of 1, 2 and 3.A grade 3 team can respond to emergency priorities of 1, 2, 3 and 4.
So basically, if the user selects emergency priority of '4', then only grade 3 teams can be displayed. I am using two different tables in the datagrid. The datagrid is populating at the moment, but not based on anything that is selected in the comboboxes. It just displays a lot of duplicates of all the records in the tables. Here is my code so far (this code is on the search button click - I have already loaded items into the comboboxes on the form's load event):
Dim sqlConn As New OleDb.OleDbConnection
Dim sqlCmd As New OleDb.OleDbCommand
Dim sqlReader As OleDb.OleDbDataReader

View 2 RepliesMy problem is that I can't populate a datgrid with the contents of a dataset. Having searched for the last few days to try and resolve this, I have given up and thought I would try here. I am using Visual Studio 2010 and attempting to create a WPF application. As you can tell from the code I am very new to this and any suggestions for improvement will be most welcome. I can see that the dataset is populated ok via the visualizer, I have a datagrid 'dgBOM' which I want to display the results. A popular solution in my searches was to add '.DataSource' but when I type the '.' after dgBOM the Datasource option is not there.
Code:
Public Sub Connect()
Dim cn As OleDbConnection
Dim cmd As OleDbCommand
Dim dr As OleDbDataReader

I am using a Dim All_PriceLists As System.Collections.ObjectModel.ObservableCollection(Of BSPLib.PriceLists.PriceListPrime) where PriceListPrime implements Inotify for all properties in it.

I am trying to build a DataTable to populate a DataGrid in VB.NET. The columns will be the username and then question from an exam. Each row will be the answers by user for each question.
So it would look something like this:
Username | What is your favorite color? | What is your favorite book?

Joe Blue The Hobbit
Fred Red The Road

That works great and gives me a table that has the needed columns, but I am stuck as to how and get each users answer and put it under the appropriate column.
I tried adding rows in the same loop, but that just adds all of the answers under the first column.
I want to populate a listview with items from datagrid view. I've been searching for solutions but it seems that all the scenarios I found were about populating listview with items from tables in database, not from another listview or datagrid view.
I'm trying this code:
For count As Integer = 0 To (DataGridView1.Rows.Count() - 1)
Dim row As DataRow = DataGridView1.Rows(count)
Dim item As ListViewItem = New ListViewItem(row(fieldfirstcol).ToString())
item.SubItems.Add(row(fieldsecondcol.ToString()))
ListView1.Items.Add(item)
But it doesn't work; it says DataGridViewRow cannot be converted to DataRow.
just would like to ask if it is possible to manually populate the datagrid in asp.net 2003 using vb.netwe usually populate the datagrid using this code, in this code what it does is it populate the datagrid base on your query , it's automated you can't edit or evaluate the data inside.
dataGrid.DataSource = ds
dataGrid.DataBind()
What if if I want to edit or evaluate the data inside the DataSet?

View 6 RepliesI need some suggestions on how to tackle this issue. I am fairly new to using ADO.NET and am running into difficulty populating a dataGrid.Basically here is what I want to accomplish:
a) on form open the dgvLOCATION populates with any records found in the database that match the customer ID that is displayed in a text box (the textbox will already have a value when the form opens)
b) when the value of the Customer ID textbox changes then the dgvLOCATION will change (I am already going to do this with a text changed event...I am just having problems with the query)
I am using VS Studio 2005 and connecting to an Oracle 10g database.I have also created a 'view' for the dataGrid since it will not any binding.Currently the dataGrid will populate will ALL database records on 'form open' if the field value of Customer ID is not null.
I am using the Query Builder wizard and when I enter the following I get an error.Select C_ID, ST_NUM, ST_NAME, CITY, RESIDENCE From CUSTOMER_LOCATION_VIEW Where C_ID = :TXTCID.TEXT
The error tells me that the query could not be parsed.
I have a very frustrating problem which is not funny to resolve. This is not supposed to have with Visual Studio 2010, NET framework 4.0. I have to be very efficient on this platform that Visual basic 6.0.
The NET platform should be very interesting on C#, and Visual Basic languages.
In Visual Basic 6.0, the Datagrid (OLEDB 6.0 version) could be populated easily using the ADODB.Recordset object by using the following line
[Code]...
The only way out for me is to use the Add items method using the items from the ADODB.Recordset to add them individually into the NET framework 4.0 Datagrid which is cumbersome code because I need to use For Loops statement etc. This is not good programming practice.I feel like I am going backwards when I am supposed to be moving forward. I use Visual studio 2010 for C# and Visual basic and this should be more fun than Visual basic 6.0 and previous C# 2008 etc. I cannot rely entirely on managed NET framework objects and classes only. I need to use all the objects available to my disposal to programme and come up with powerful Microsoft applications.
