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?
ok i have image that i bind info in it and i want to read the info now from file (FileStream) its workbut i want to do it not from file so i need to use MemoryStreamhere the example that work and how i do it now how i make it work with MemoryStream (with byte = My.Resources or PictureBox1.image)
Using FS As New IO.FileStream(image, IO.FileMode.Open)
FS.Seek(0, IO.SeekOrigin.End)
While Not FS.ReadByte = Asc("|")
[code].....
I try to load image byte to memory and read it in memory (not from file - string)
with FileStream i do it like FileStream(image, IO.FileMode.Open) image = string of file path
so i want to do it with MemoryStream(image) image = image byte
i try many things but still cant get it [code]...
I declared the variables with in the first module to be loaded
Module Mod_Global Public DtFRM As String Public DTTo As String I can load the variable and read it with in the module. Ok, good so far. But sending the code to another module results in nothing in the variable.
I can't really explain what I'm trying to say but here is an example.
Example:
Created 1 Listbox named Box1
Created 1 Button named Load

I have been playing around with VB for a while now, but still need to consolidate some thoughts. I was wondering if anyone could answer this..... Whats the difference between say Form1_Load and Public Sub New() on form startup? The reason i ask is i normally add calling subs to the form load process, but can you add any startup calls to the Public Sub New(), and if so, what is the advantage?

I have a csv file with say 20 lines of 6 numbers. I need to be able to select say line 14 and then load the 6 numbers into a set of 6 text boxes. I can get them into the text boxes once they are loaded into an array, it's getting them into the array I am having difficulty with. I ahve tried numerous scripts form off these forums and the net but can't get one where I can specify which line the information comes from.

VB2008: use a BindingSource on numerous textbox fields. The form loads ok and all of the binding is working fine. My problem is that I need to set certain form defaults based on the incoming data prior to showing the form. I cannot find a form event that fires after the data is bound, yet before it is displayed. I tried Form_Activated and several more. The bound fields are still showing zero-length strings. This wasn't a problem in VB6. Can anyone point me in the right direction?
View 1 RepliesI am trying to write a graphing program that will draw on/in a picturebox during the form_load event. It works if I connect the code to a button event and click the button but the exact same code in the form_load event seems to do nothing. I've tried calling cmdDraw.PerformClick() and cmdDraw_Click() and although the Draw button works when I physically click the button with the mouse, nothing seems to happen when these functions are called during the form_load.

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 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

The strange thing is that for other forms in my code it works well and starts with the form_load function.
i have a problem: I have a Form_Load-Method which is not doing all the commands in it. It just interrupts and jumps to the "Form_Paint"-Event, eventhough i did not yet paint anything or invalidated any object. The Form_Load-Method is this:

the dashed line indicates the point of termination. the for-loop is simply not done. i tried it with stop points and the last point it stops is the ReDim-part. this can only mean, that the ReDim-Command forces the program to leave the method. but the for loop is never done afterwards. Can you help me? Because i really dont get it.

The application I'm writing requires the user to select a certain directory on their hard-drive (a game directory), which is saved to the Settings. If the directory is not selected, my application can't work. So, when the program starts for the first time, the directory setting will not be present, and I want my application to ask the user to select the correct directory before the application starts (the main form is shown). I used the following code in the Form_Load event of my main form:
vb.net
If My.Settings.WolfPath = String.Empty Then
MessageBox.Show("Please select your root 'Wolfenstein - Enemy Territoryetmain' mapping installation.", "Select W:ET Path", MessageBoxButtons.OK, MessageBoxIcon.Information)
[code]....
It looks pretty complicated (probably too complicated) but I wanted to make sure that the user cannot continue until a valid directory has been selected. So when the user cancels the folder selection, my application should end. If the user selects an invalid directory (it should end in "etmain") it should display a messagebox and show the folder browser dialog again. It should keep doing this until the correct path has been chosen.The problem occurs when an invalid directory is first chosen. The messagebox does show, but it shows behind all other applications! It took me a minute to figure that out, because I could not find my application anywhere, but Visual Studio still said it was running... After finally finding the messagebox behind everything else, it seems that now everything comes up behind everything else! When I click OK on the messagebox, the new folder browser dialog also shows up in the background, etc, etc. If I then choose a valid directory, the application loads the main form in the background...
I thought at first the problem would be the fact that I am running this code in the Form_Load event. A better place perhaps would be a Sub Main() from which the main form would be loaded explicitly (Application.Run(mainForm)). However, I can only select Forms as the Startup Form. If I disable the "Enable application framework" checkbox I can select the Sub Main() as Startup Object, but all the visual styles are lost...?
