Controls Not Reflecting Changes On Form Vb2010
Feb 8, 2011this is somewhat related to my previous issue which was solved: [URL] Now my problem is none of the affected controls are changing on the form. The form itself is not frozen as an elapsed time is going fine on it. when I "F8" thru the code the I see the controls contain the correct values and if I do a messagebox display of the control contents it displays the correct value. but the controls themselves do not change on the form. for example: label1.text will still show blank even though thru code it contains "test". what am I missing here?

Multiple Forms - Declare And Instantiate Second Form On Program Start - Use Button Simply To Show Form?
Jan 14, 2010I have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code:
Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
3) Something else?

Use A Progressbar To Show On Main Form And Then Finish When Next Form Is Loaded
May 12, 2009I am trying to use a progressbar to show on main form and then finish when next form is loaded, I have got this code.
1. When I click on button, it must open next form, but the next form must only open when the data in my list box has been loaded from Access Databse. When I run my program, it only shows the progressbar and don't open the next form.
Main form code:
Public Class Main
Dim PB As ProgressBar
Private Sub main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

.net - Open A Form With Form.Show First Mouse Click Is Ignored?
Nov 12, 2009Using the code below:
Private Sub ShowDropDown()
Using f As New DropDownForm
f.Visible = True
Do While f.Visible
Application.DoEvents()

This was a guess, after looking at the Form.ShowDialog method in reflector.My question is, is there a managed call I can make to acheive the same result, and what does a button click do that other clicks don't?
ETA: The problem does not occur if I open the form using a key.
Form.show() Loosing Context In Originating Form?
Nov 8, 2011This is a database app where I am trying to check for possible duplicates and give the user the option to keep the new record or assign to an existing record.In form1 the user will enter data into a textbox. I use this information to build a bindingsource.filter. Then I call another form (form2.show()) to display results to user and get user response. This part all works correctly.
The problem is that as soon as form2.show() executes, I loose the contents of the textbox - and it appears that I am no longer in the bindingsource.addnew() method.

Jul 25, 2011I have a series of methods being called for my networking code. An event gets fired from the networking thread. Inside this event, which I've hooked into from a singleton class, I route messages to form level methods which they register on form load to handle certain messages they care about. Inside of these form message hooks I need to close the current form (which I was able to do) but also show a different one (which is giving me the trouble).

VS 2008 Form.Show / Form.WindowState?
Oct 26, 2010I have a dual monitor setup on my computer. My program has multiple forms. I've designed the program to check which monitor the main form is currently on and to open the secondary forms on the current monitor. When the main form is on the primary monitor the secondary forms open as FormWindowState.Normal which is the design-time setting for the secondary forms. If the main form is on the secondary monitor and I click to open a secondary form then the secondary form is to be displayed as FormWindowState.Maximised.
[Code]...
So I moved the Form.Show line to after the Form.WindowState line. This works fine when the Form.Show process is very quick. The problem is that one of the secondary forms downloads some information from the internet so it takes about a second to finish the Form_Load process. When I had Form.Show first the form would not appear on screen until the Form_Load process is complete, so the delay was in the form appearing at all which is how I prefer it. With Form.Show last the form appears on screen immediately but appears mostly blank and unresponsive until the Form_Load process completes.
I would prefer that the form not appear at all until the Form_Load process is complete but I would like it to appear in an already Maximised state. Is this achieveable? It doesn't seem that complicated but I just can't figure it out.
SQL Data Access: VB2008 / VB2010 - WinForms - Create A Datasourse And Drag / Drop Fields Or Tables On A Form To Create A Grid
Oct 22, 2010I have used VB (versions 2 - 6) through many years; however, I am crash-course training myself into the VB2008 / VB2010 world kicking a screaming. I would like suggestions as to what SQL database access method should I focus more on in my learning process without making me feel that I'm a million years behind. I know I have WinForms where I can create a datasourse and drag / drop fields or tables on a form to create a grid (not really what I'm looking for).
My trouble isn't so much designing the form but in how I access the database. Theres XML, LINQ to SQL, ADO.NET, and many other methods. Not only do I need to grasp these methods quickly but I also need to know what type of projects I should create. What I mean is...I was thinking that I would design a WinForm app; however, I see that there are WPF apps and others to chose from. This is getting deep. I know it depends on the project that I'm working on. My plans are to write an app based off of either an SQL Express 2008 or SQL Server 2008 database. This first app will be standalone for now but may later become multi-user. I know I'm far behind on my learning curve coming from VB6. I have read a bit on VB2005 / 2008 / 2010. I own
both VB2008 and VB2010. I use VB2008 at work. I know ADO.NET is still alive but by what I read online, it's a dying method and is only kept for backward compatibility. XML and LINQ to SQL and other methods are all pretty new to me.
.net - Form.ShowDialog() Does Not Show Form?
Apr 20, 2010I've come across a situation where I try to run a simple line of code in a method Dim res As DialogResult = frmOptions.ShowDialog()but nothing happens. The dialog box will not appear. If I run this method from another location in the code it executes fine (i.e. displays the form in dialog mode and code executes fine thereafter). Hence, it may be the way in which I arrive at this code that is causing my problem, but I cannot see to find what is wrong.
When I pause the debugger the line of code is highlighted in green but I can't see to step over it or into it what may cause this to happen, or what I should be looking for that might be causing the problem??
