Imports System.Data
Imports System.Data.OleDb
Public Class Form1
Dim con As OleDbConnection
Dim cmd As OleDbCommand
[CODE]...............
The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.

I have a combo box on a form. I have a SelectedIndexChanged event, that displays a message box when the combo box has another item from it selected. This works fine. However when the form is loaded, I initially want to set the current drop down box item from the database, then AFTER I have set the current value, I want this event to work. Problem is from the get go when the form loads it asks me the question as its being changed from 'no data' to then be populated with a bunch of data and an item selected.

I'm creating a dynamic combo box and adding to a form. I'm trying to fill the combo box with a DataSource from an ArrayList and then selecting an item in the combo box based off a value from a property.Problem is, the combo box items don't get bound until after the Form_Load event has finished and the form is visible. So the combo box is empty when I try to set the selected index of the combo box. See code for what I'm doing in detail, and refer to comments in

When the form loads I want to fill the combobox with the data present in the database. So I did the below
Private Sub BindCombo()
con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:UsersGautamDocumentsVisual Studio 2005ProjectsF1pracF1pracBank_Account.mdb")
con.Open()
cmd = New OleDbCommand("Select * from BankAccount", con)
[Code] .....
Doing this code the data is added up in the combobox dropdown list. But when I am selecting a data from the combobox dropdown list,the all the corresponding data of the other combobox also get filled automatically. I don't want to let the other combobox filled with their data automatically....

I have a databound combobox that displays a list of items, and I have a windows form that opens after clicking a button that allows me to make changes to the table that the combobox gets it's values from. When I make the changes and save them (successfully) and return to the parent window, the changes aren't reflected in the combobox. If I exit the app and launch it again the changes are reflected perfectly. I've tried me.combobox.refresh() on the forms GotFocus event, but no luck.

I have a few combo boxes that need to be loaded up once and displayed multiple times (whenever the main form is opened) The reason for this is because it's taking about 10 seconds for the form to load each time it's opened due to unnecessary re-querying.
Here is an example of what I have as a combo box source and what I've done.
I've put the query, connection, etc... in a module and call it on the login form - i don't get any errors but the data does not load into the combos.
'In Module
sql = "SELECT DIR_ID, DIR_NM FROM LTC_FBS_DIR ORDER BY DIR_NM ASC"
RConStr = String.Format(RConStrFormat, LoginForm.txtUser.Text,

In VB 2008, I have a Parent form with a combo box on it. There is a child form also with a combo box on it. I want to be able to change the values on the child form based on what the user selected from the main form. The user launches the child form from a toolbar on the Parent form. The following code is run:
[Code]...
What I want to do is if the Parent's combo box has "Red", "Blue", "Green" values and the user selects "Green", the child form's combo box(With the same values) will also change to "Green". (I do not need to change the Parent form if the child form changes.) I've tried changing the Child's combobox from the combobox's change event on the Parent form, and the code runs, but nothing changes on the child form.

I would like to load a combobox with some values from an access database. On form load I load my information into a data grid view but if the user wants to add more information or edit what is selected in the DGV I will enable some text boxes and a combobox to show the selected data. I have not issue loading from the DB into the text boxes but the combo box has me a bit stumped. I have 3 columns in the database, periodno, start date and end date. I want to display the start and end date concatenated together. When the user selects a period and hits the button I want the dates to set a variable with the periodno that matches those dates.

How do i load the Main form of a WPF so that a seperate thread goes and gets data from the database while the form is in an apartmentstate? (drag-able / movable) I Know this is possible with opening a new window from your main form like this :
Private Sub openOrderWindow()
Dim OrderWindow As Orders = New Orders
OrderWindow.ShowDialog()
End Sub
[code]....
I've tried putting MyBase.ShowDialog() and .Show() and .9000+ other things The only benefit I've got out of using a seperate thread to load from the databse is i can see the screen right away (as oppose to it being a transparent box until it loads) but i cannot move it around or minimize it?is there any way to make it Movable while it loads?
