I have a pile of checkboxes on one particular form and would like to clear them all at the form load rather that saying chk1.Checked = False for all of them.
Here is the code I was trying to use but 'checked' is not a member of Systems.Windows.Forms.Controls.[code]....

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.

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?

I have two forms. Form A and Form B. Form A has a datagrid that is populated from a SQL Database Table query. When a button is pressed Form B is launched that allows you to add a record to the database table. I need for the datagrid to be refreshed and show the newly added record when I close form B and go back to the parent.

i am having an issue populating two combo boxes on form load. The program will connect to an access database and pull data as instructed. Then as it pulls each record it puts it into the combo box.
This was working.. atleast i think it was. i dont recall it ever not working, however i wasn't looking for it.
My problem is that if when i load the MDI parent form and have it skip the selection form and the login form and load the next form in the sequence, it loads everything perfectly. However if the select form is loaded first, then the login form and then the form i need loaded, it will not populate. The only difference between the two different loads is that the login form calls a function that loads the form as a new project.form
I did this so that I can have multiple forms open at a time. I am assuming my problem is that I need to get the child forms handle then populating controls using that handle? but i think if I had to do that then I would beable to populate the comboboxes on the first form load using the login method of opening the form.
Here's my code.
vb.net
Private Sub frmLine1t5_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.Text = "Line " & LineNumber & " Test Form"

I fear that there is something obviously wrong with my code, but I have come across a situation where the Form.Load event is not firing when I create and show my form. The form is not subclassed (as I've seen some problems with that in some searches), and I am not getting any errors thrown when I step through the code in the debugger.
I have a break point set on the IDE-created form load function (which does have the Handles MyBase.Load signature suffix) but the breakpoint is never reached and the form does display and work.The form is passed three arguments in the constructor but the IntializeComponent() function is called before anything else is done.

I have a small program which draws some lines with a method called: Drawlines But Now I want to call this method in the load form routine. So if the form is loaded the lines should be drawn in the picturebox. But is this possible or should the form first be loaded completely before you can call methods in that same form?

I open a form using .showdialog and load some info onto it. I have code that runs on the MyBase.Load event. Basically, I have a Try, Catch, End Try block and if the Catch executes in preparing my information, I want the form to stop loading i.e. give a message and not show at all.

aside from the difference mentioned below, what are other difference the two events might have and how will affect the application as a whole? What is more preferred to use and why?

*Do stuff*
Form shows up on monitor
Form Shown:

I have a code which when used, firstly application will run the Splash Screen application. Splash Screen will be active for several second, and then the main of application will show in full screen. Before the user use the application, user must Log in first. This works but the problem is that it loads the splash and login form twice. To worsen the situation, the second login form that appears gives access to the system even when the cancel button is clicked while the first login form just works fine. My codes for the three forms are as listed below:

This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:

I have two forms , first one is search and second is showing the data searched by first form search criteria. When the search query runs it takes lot of sql server resources, so I have passed that query to second form, it searches in database and shows the results. But if the results are not found I wish to close the second form in Form load event. As Second forms form load event searches for the record. I tried to use SecondForm.close in SecondForm.load event but failed to do so.
