Form Loads Before Completing All Of The Form_Load Event Code?
Nov 27, 2009
I am having a problem in Form_Load. When the following code executes the form pops up with out executing any further code: Me.TblAssetsTableAdapter.Fill(Me.ITP400_IP3_ADataSet.tblAssets).
I am trying to use Form_Load to populate values in a ListBox control from an Access database table.It appears the problem was in the Compile settings. It was the 'old' problem of using AnyCPU on an x64 machine. I changed the Compile setting to x86 and the problem disappeared.

I have a problem concerning the Form_Loading event: When I want to load a new Form (ImageDisplay) the ImageDisplay_Load Event is not executed first.
Instead it runs through the global variables definitions and then executes a Private Sub called numericupdown1_changed.
The numericupdown1 field is part of the form I want to load and has not been touched.
That is my calling sequence:
Private Sub Dispalydata_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Dispalydata.Click
Dim myDisplay As New ImageDisplay
[Code]...
The strange thing is that for other forms in my code it works well and starts with the form_load function.

I am using visual studio 2005. I want my form should be editable, when i am pressing some function key. Like, when form load, no field should be editable. When i will press "Ctrl + N" or "Ctrl + F2" Key then only form should be editable. Is this possible?

Back in the VB6 days, I could count on frmWhatever_Resize() to be fired when a form is loaded. That doesn't still seem to be the case. Since my resize event is filled with all the code I want that adjusts the size and placement of things, I decided to just call it from the end of the form's load event. That has no affect. I'm guessing that the form isn't actually shown until form_load is finished?
is there some other event that is fired when a form is shown, so I can call my resize code there?

I have a form that I call from another form. Whenever I call it using form.showdialog() or form.show() the form appears, but it never executes the code that is in the form_load sub.
What's the deal? I call other forms in the same manner and they all load and execute the load code without issue.

Create a Visual Basic project with a Form that displays a seating chart for a small theater. Assume that the theatre has 25 rows and each row has 10 seats. The following image shows the completed main Form for the solution.
Write statements in the Form Load event to instantiate an object from the splash screen form and then display it as a modal window. Write the statements so that when the main Form loads (after displaying the splash screen) it will dynamically create the 2-dimensional array of CheckBoxes on the Form. The CheckBoxes should be created inside a scrollable Panel control instance. Above the scrollable Panel control instance display the column numbers (1 to 10).

I was under the impression that there was not much difference between Sub New() and Form_Load. However, I found one weird bug...Add a combobox and a label to a form, and the following code:
Public Class Form1
Private mstrOutput As String = ""[code].....
The label text shows that the value of ComboBox1.Text changes between Sub New() and Form_Load.Is this meant to happen?

First, I launch a website in Internet Explorer from VB.net and automatically login the user with ther username and password. As soon as the username and password fields are automated, I send "enter" to the website so it goes to the next website. This part works perfectly. However, my problem is that i want to send a mouse click event, which i have already written, to click a hyperlink on the next website page. I tried a few different things, none of which worked. My program is automatically logging in the user and doing the mouse click event at the same time. I have tried to use the "sleep" command, but the mouse click event is still not executing after the second webpage loads. I have tried using nesting "If, then" statements and that has not worked either. Does anyone know how to make sure the webpage fully loads before executing a sendkeys routine or a mouse click event? This is my code thus far:
If (Search.ComboBox1.Text = "IWR") Then
BlockInput(True)'this disables the mouse and keyboard
Dim IE As New Object
[code].....
There are no errors, everything is just executing all at once instead of letting the second webpage load and then executing the mouse click event.

I have a form that is built and loaded dynamically when File/open is selected.however I now want to use the same code to open a default file and populate the form using the Form load event to call:
Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click how would I do this? Just incase this doesn't make sense, I want the same code to run during form load as if the user selected file/open but do not know the syntax of how to call OpenToolStripMenuItem_Click() from form load.

I have created a class which generates a form in code. I have hooked up the buttons and a text box so that they work. Now, I am trying to hook up the Resize event (and probably will need other events) for this form. How do I do that? If I can understand how to do it for the Resize event, I should be able to apply that to whatever other events I might want to use. I can't just put "Handles frmMyForm.Resize" or "Handles Me.Resize". I get the message "Handles clause requires a WithEvents variable defined in the containing type or one of its base types." This all has been a learning experience.

Within the program, there is a button that opens a file inside of a second form ( DocViewFrm ) and it works fine the first time around. Within this new window, there is a button that uses Me.Close() to close the window and return to the main window. Upon the attempt to open this second form a second time, the program crashes on the Me.DocViewFrm.Show() line. The error message reads:
An unhandled exception of type 'System.ObjectDisposedException' occurred in System.Windows.Forms.dll
Additional information: Cannot access a disposed object.

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...
Code:
Imports System
Imports System.Windows.Forms

I tried to make a menu for my game, but when I placed the code into the form loading event, it wouldn't show. Then I placed a button and moved the code into the button click event and it worked. Thus, I know the code shouldn't be wrong. How can you make the graphics( as in lines, rectangle,etc) show up when it starts up?

I have two data tables within my data set that are loaded onto my form on form_load using statements written in code (not the designer. When I change a value for the first table via a text box the change is made to the data set. But when I try the same for the second table, the change doesn't remain in the data set when I switch to a different company and come back. I query the second table using the primary key of the first table but no code is needed when I change the values for the first table so I don't understand why the same doesn't work for the second when I change a value via a data-bound text box....
Here is my code that initially binds the data:
'This is used to read our data from the data base
Public Sub Read_Data_SQL()
Call Clear_Bindings()
[CODE]...
Here is the code I call when the selected index of my company combo box changes to have the second table reflect that of the first:
'This sub populates any information contained in the Contact2 table
Private Sub Update_Contact_2()
Dim Company As String = cmbCompany.Text.Replace("'", "''")
