VS 2008 Form Load Unsolved
Mar 22, 2010
First I have already asked a mod to delete my other load form problem thread for feature reference if someone ask.My last thread was not solved do to the fact of me giving up an marking it resolved. I was trying to resolve the issue with my form not loading to the following an just gave up cause its been a cat an mouse game as I stated in the last thread.My project is having difficulties with a code. For some reason it's not letting frm FakePM. Show open the form.Ive used this over an over time an time again, its just not doing it now. The following code opens my Fake Pm part of my program: [code] An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object.Now Ive used frmfakePm or frmAbout or frmOptions for other form applications an its never given me this kind of error.It gives me a error on my FrmFakePm form of my Private Answer Strings, The Dim code is in green, the Private Answer Strings are in yellow. I don't know why this is doing such a thing.

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"
[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 can I load a form and allow it to run it's code in the form load but keep it not visible. I want it to do what it needs to but but not display.

It's probably bad practice to rely on the form load event by running too much code in it? I have a lot in there just to get things setup for the program and much of it gets repeated later on in other events, so there is some redundancy. But is it good practice to make sure that you never "count on" anything in the form load event?

I have a form that is the main form.I don't want it to show when it loads, but when I do Me.Hide() in the Form_Load event, it flickers visible before it hides. Because before I made this form the main form, the one I was using previously didn't flicker.

I want to pre-load a number of images from the web, so that I can display them in a form, and scroll through them without delay. It can be a large number, but i only need to pre-load perhaps 20, and then remove/add in advance, as I scroll through. The images will typically be .GIF or .PNG, of quite small size, <50kb. The link for any single image will look something like this: [URL]..and I will keep a list of all the links I need to access.
What "type" shall I use to store these images? And how do I make web requests to put the data into this type? I guess it will be more convenient to keep this as in-code list of some memorystream type (?) instead of saving them to disk and having to deal with file names and stuff..? Also, what type of control shall I use to display such images? Do I use a PictureBox?And if a memorystream is indeed the best choice, how do I make this show in the picturebox?

Dear all, I'm new in the forum. I have a simple but annoying problem: in a ordinary form I added a label (Label1) and a button (Button1) with the followiing handler.Well if I press Button1 my dot dashed line is correctly drawn over Label1, but what I need is that program automatically does it on form loa
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Graphic As System.Drawing.Graphics

I try to run a custom sub procedure from the form load event. It keeps crashing. I believe it is because all of the controls are not loaded and the sub procedure makes use of some controls. How can I make sure everything is loaded before the sub procedure is run?

just wondering if it is possible to have a form and then load up a control on that form but so it runs in a different thread to its parent... i tried:
[Code]...
But it still seemed to be running on the form's thread And just so you know ctlMTTest is just a control that has a button on it, that, when you click the button, a loop runs.

I have managed to develop a form which allows me to add a record to an access database using Adonet. The last few fields added are populated when i place the mouse over a floor plan image on the form (provide geographical location) and capture the x y coordinate. Prob im having is how on another form i get the points to automatically re-draw on a form with the same content (floor plan on it. I can obviously retrieve the data set using a data adapter/data table just cant make it draw on top of the graphic automatically.

Load , Initialize , Activate . What's the difference among them ? Up to now I was used to the classic VB6 events , but it seems that in .NET they are different . I was used to these ones :Load / Initialize : both the first step before showing a form . One appeared in VB6 , the other in VBA .Activate : triggered when a form is selected .However I thing that now , not only they differ , but they also come in a different order ...

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 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?
