I'm trying to execute different code depending on the button clicked (button 4 or 5) on Form1, but when I click on button5 to activitae the code on the Form2's Load event everything is Ok, but when I click the back button to return to Form 1 and click on the Button4 to activate the code on the Form2's Load event again, it doesn't active the Form's Load event, is there a way to form the form load event every time I access it from Form1?

VB2010 Express Versus VB2008 Express?

Feb 25, 2011

Is there any advantage to using the VB2010 express version versus the VB2008 express version? Can they be installed side by side or will VB2010 express replace VB2008? I have no issues with the 2008 version, so I don't know if installing the 2010 version would be of any advantage.

VB 2010 - Express Forms - Load Next Form In Same Window

Feb 10, 2011

I have a very large program I would like to write but think starting with a smaller test program would be a good idea. What I want to know is: I have a base Form from which a user clicks a button to answer a question (Answer A, B, C, or D) which if the answer is correct will pop up a "Correct! answer response in a separate window. This is ok for now, however, when the "proceed to next question" button is clicked, I would like the next question to appear in the original base form window.

Right now it pops up in a separate window and I'd rather not have 20 windows open at the end of the quiz. How do I load the next form in the same window!? Obviously it's possible and could be something I'm completely overlooking, and I've also read that I could replace all data with the next Form. I have searched "Visual Basic load form in same window" and came up with results, but none of what I'm looking for.

IDE :: VB2008 Express Form Designer Error : An Error Occurred While Parsing EntityName.Line 2, Position 62

Nov 24, 2010

The Form Designer in the IDE is no longer working properly. When I create a new project, the Form Designer will work, but after I save it and close the IDE and reopen the next day the Form Designer no longer shows the form and instead says "To prevent possible data loss before loading the designer, the following errors must be resolved: An Error occurred while parsing EntityName.Line 2, position 62" If I click ignore and continue, then it just displays a blank form with no controls. The problem appears to have started after I unistalled and reinstalled VB2008 Express.

.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.

What Happens Before Form Load Event

Dec 21, 2011

I have a form and initialize some global variables on its Load Event. There is a TextChanged event in one control (a textbox) that uses that value. The TextChanged event of the control is triggered before the Form's Load event even if I do not change anything on the TextBox, it looks like that happens when the control is loaded. Why is it doing it before the form? and what event can I trap in order to assure it's the first thing that happens?

Its as simple as this:

vb.net
Private Sub PackOutMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ActiveFlag = False

[Code]....

My guess is that the msgbox should not appear until the flag is set to true somewhere in the code and then change the contents of txtUser, but it is shown before the form.

Dynamically Changing The Image Of A DataGridViewImageCell Isn't Working On Form Load

Sep 27, 2007

I have a DataGridViewImageColumn that should display an image for only certain rows. After I bind a generic list of classes to my datagrid, I loop through each row and update the image cell with an image that is an embedded resource for the rows that require the image. This works great if the form has been fully loaded. However, when I attempt this on form load the image doesn't show up? I also can't perform simpler things such as changing the row background color on form load. Should I be performing this logic in a different event after form load?

For i As Integer = 0 To dgvRoles.Rows.Count - 1
Dim imageStream As System.IO.Stream = Nothing
imageStream = Me.GetType().Assembly.GetManifestResourceStream("MyApplication.Timer.png")

.net - DbCommandBuilder Not Working As Expected?

May 27, 2011

I want to fetch data from a database table modify it and update it without being dependent on the database provider and the database structure, because it will be part of a library.My first attempt was as follows:

'factory defined somewhere else as DbProviderFactory
'connection is a working DbConnection
Dim selectcmd As DbCommand = connection.CreateCommand()[code]....

it did not work. After further investigation I figured out that the Commands the CommandBuilder generated were useless, because it inserted ? instead of @param1 for all Parameters. It generated something like INSERT INTO tbl1 (field1, field2, field3) VALUES (?, ?, ?) for the InsertCommand.I would really like to use the CommandBuilder, because it is simple and I don't have something complicated like JOINS.

Asp.net - IsNothing() Not Working As Expected?

Apr 12, 2012

I have a query like so:

Dim clcexists = (From p In dbContext.Signatures _
Where p.StudentID = people_id _
And p.ContractType = "clc" _
Order By p.ID Descending _
Select p)

Later I check whether any rows exist in clcexists using IsNothing like so:

If IsNothing(clcexists) Then ' If no CLC is on file.
clcfirst = Date.Now.Subtract(year)
clcdate = clcfirst

[Code]....

But IsNothing() is not functioning like I expect. There is no row in the results table, but it is still acting as if there is and going to the Else clause.

IDE :: Program Not Working As Expected?

May 18, 2010

I am running Windows 7 pro and using Visual Basic 2010 express.I have written a small program to switch on a USB relay which is controled by a serial port.I have debuged the program and it appears to work correctly. I have published the program and if I start it from thr run menu / desktop shortcut / or through explorer it works as expected.

However I have tried to run it by the Task Scheduler and then it fails to run as expected. I have a small section of code that checks to see if the serial port is present if not I have used messagebox.show to ask for the relay to be pluged in. In every case other than when running through the Task Scheduler the messagebox works with the Task schedulerit doesn't show the messagebox and the program hangs I have included the code I have used.

Dim retry As Boolean = False
Dim data() As Byte = {255, 1, 1}

Looping Not Working As Expected

May 22, 2011

[URL]. I have a Multi-Line textbox with several accounts in it. They are in email@email.comassword format on separate lines. All the code is right, but it goes really weird and loops like 3 times before logging in. Eventually logging into the last account on the Textbox instead of the first. It should just login to the first account...Logout....Login to the second account...Logout and continue the process.

If you want to test it, just put a web browser and a textbox1 multiline box, a button and enter a few working hotmail accounts and you'll see.
Check line 17
Looks like a lot of code, but line 17 is the only bit that needs to be looked at. The rest is just junk/non-relevant to this problem. It separates the accounts perfectly and stuff, but just wont login in the right order.

Variable Not Working As Expected?

Jul 28, 2010

I have declared a String variable(PC) for use within another String variable(currentQuery) to form a SQL statement to pass to my SQLDataAdapter variable.

I'm performing this action to change the string variable(PC) for the different onClick events I have.

It seems i can change this variable (PC) within my onClick event handlers and the 'PC' variable will change when I apply it to a testing Text Box 'testTextBox' but not for the currentQuery variable.

Do i need to perform this action as a function or am i missing something obvious - code below - I don't want to spend time writing a function to return a string value for my SQL statement if i can just tweek something in my code (below).

Partial Public Class IVMain
Inherits System.Web.UI.Page
Dim DBConn As New SqlConnection("Data Source=hnaServer;Initial Catalog=Hnastatus;User ID=Test;Password=test")

Form's Load Event Not Called?

Apr 25, 2011

I was having a problem with the debugger not stopping at breakpoints. After a lot of work that yielded no results, I realized that the problem was occuring in the form's load event and subs called from that event.

The problem is that it appears that the load event is not being called. Other startup forms in other projects in the solution seem to be working ok.

what could be keeping the the Load event from working?

VS 2010 Event Before Form Load?

Apr 30, 2011

so I have the following

Try
Dim username as String = My.Application.CommandLineArgs(0)
Dim password as String = My.Application.CommandLineArgs(1)
Catch
Msgbox("Cannot launch")
Application.Exit
Exit Sub
End Try

I placed this in the form's load event. What I want is for this check to run before the form even loads.If an error occurs, the msgbox comes up and the form is never seen. When I try the code now, the form comes up the msgbox shows. When the user clicks OK the form closes. I tried placing it in the form's designer but the designer tries loading the form any way. How do I get this check to run before the form shows?

I wish for my Form when it Loads, initialise and then call a sub and do some stuff eg perform a plot. If i place a button on the form and click it the sub works fine.This task was simple to do in VB6 but for the life of me I cannot get it to work in VB.NET. Has the Form-Load event changed in some way with .Net?
