I have a piece of code like...
If FRM_LOADED(lngID)
Then
FRM_X(lngID).WindowState = FormWindowState.Normal
[Code]......
and in VS 2008 the form (FRM_X ) loaded and invoked the Load method. After upgrading to VS 2010 the same code executes and displays the form but the Load method isn;t executed.
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.
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?
I've developed an application using VB 2008 Express and there are some customers using it,of course they have framework 3.5 installed.Can I upgrade to VB 2010 but keep target of my project to framework 3.5 (there is a option on Compile tab to chose target framework version),is it a good idea or not ?
View 5 RepliesWe recently upgraded VS 2005 to VS2010 and converted an application seemingly without any problems. But when deployed to the customer they are getting intermittent errors at seemingly random places in the program which force the application to close and AccessViolationExceptions being logged to the Application Event Log.

I am working on upgrading an old Access 2000 database to VB .NET (2010). There is one form that I am having trouble figuring out how to build so that it works similarly to the Access form. In Access, there is a header, detail and footer for this form. The objects in the detail section only need to be created once and Access will "copy" them for each record in the database and fill in the appropriate information (the form objects include buttons, textboxes, comboboxes, etc.).
How can I do this in VB .NET? Each different area that is chosen will have a different number of sections. I've thought about using a GroupBox, but I'm not sure how to make that work.

I have to update and old VB project made with Visual Studio 2005 that uses Crystal Reports to Visual Studio 2010. I've installed the Crystal Reports plugin for VS 2010. I can compile the program under VS 2010 but when I run it and try to generate a report I get many errors popping up from the Crystal Reports Viewer. When I compile and run the project in Visual Studio 2005 (with the old Crystal Reports plugin that comes with it) everything works fine.
The problem is caused by SQL Expressions that are SELECT statements that are not enclosed in parenthesis. This is a problem because there are ~250 SQL Expressions like that in the report file (and it's not the only report with this problem). When I look at the .rpt file in Crystal Reports 10 and use Database -> Show SQL Query the SQL Expressions have parenthesis around them despite there being no parenthesis around these statements in the SQL Expression Editor. When I do the same in Crystal Reports 2008 the SQL Expressions don't have the parenthesis included.
Is there a way to make Crystal Reports 2008 or the plugin in for VS 2010 automatically include the parenthesis around SQL expressions, or was this feature removed? If it was removed, is there anyway to enclose the SQL expressions in parenthesis other than editing each one manually?

I have a button and various other controls that when clicked, calls as sub. However if the user clicks the button or any of the other controls multiple times, the sub appears to 'stack up'. For example, if I click the button 10 times, and then some of the menu items that trigger it 20 times, the sub would 'stack up' and execute 30 times total. How can I have the sub cancel calls to itself if its called again? I basically only want the latest call to it to count.
Heres code to reproduce it. Just a button on a form.
Dim intTotalTimesClicked As Integer = 0
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click

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?

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.

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

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.
