VS 2005 - Form Load - Retains The Previous Values During The Form Load

Jul 27, 2009

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.

Form Load Doesn't Clear Previous State?

Dec 6, 2009

I have several forms that are "reused," or vistited more than once per each time in the whole program.  In VB6, using Form.Show() would show the form in its original state (the state is was when created in the designer).  After closing this form (Unload Me), showing it again would still show the form in its original state.

I am coding in VB.NET 2008, and noticed that when I reopen a form I had closed during a session using my program, the form is in the state it was when I closed it (labels and listboxes filled with data), and not in its original state.  I currently have the Form.Closing event filled with code to clear all of the controls, but I think that there must be a better way to "clear" or "reset" the form.

VS 2005 Label Font Changes On Form Load?

Mar 6, 2010

I have set my forms font as "Segoe UI, 14.25pt" and have just placed an single label on the form.

Upon placing the label by default it gets the forms font i.e Segoe UI, 14.25pt

i have placed the following code on the labels textchange event

Private Sub Label1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.TextChanged
Dim f As New Font(Me.Label1.Font, FontStyle.Italic)
Label1.Font = f
MessageBox.Show(Label1.Font.Name)
End Sub

Now when the form is loaded , i get a message box showing the labels font name as "Microsoft Sans Serif"

The labels font size also changes to 8 but it is italic.

Why is this happening? And why does the textchange event occur on the form load?

Load The Main Form Of A WPF So That A Separate Thread Goes And Gets Data From The Database While The Form Is In An Apartmentstate?

May 15, 2012

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?

VS 2008 Populating Cbobox On Form Load For A Child Form?

May 14, 2009

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"

.net - Form.Load Event Not Firing, Form Showing?

Nov 9, 2010

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.

Form Close During Form Load?

Mar 9, 2010

Basically during the form load event i carry out some checks to make sure i have database connection and a valid login, if these items fail i catch the exception and display a messagebox and change a boolean variable to false.It then goes back to form load where i have an if statement which is if boolean variable = false then me.close

Trouble is this runs through to the conclusion of the form_load sub and then attempts to load and throws an instance of an object type exception.I kinda understand the logic that i am trying to close the form before it has loaded, so put the close command in the form_activated routine, however this still eventually sends me back to the form load sub and tries to load the form, and then throws the same exception.

My.Forms.Form1.BedrijvenBindingSource.DataSource = My.Forms.Form1.Docregdata2DataSet.Bedrijven
