VS 2008 Does Not Work When Form Loaded Again
Oct 26, 2009
I have a very simple form with a combo box named txtRoomType bound to ROOMCODESBINDINGSOURCE and a DGV bound using ROOMPRICINGBINDINGSOURCE.
Public Class frmShowRoomPricing
Private Sub frmShowRoomPricing_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
When I check the value of txtRoomCode when the form is loaded for a 2nd time it tells me it is blank, but there is a value in it. I think the fault is in the form_load, but I do not know why.

How do you check to see if a form is already loaded, ie if it is already loaded bring to the front else load the form.

Is it possible in VB .NET to find out if a form is loaded? Also, is it possible to find out if a form is shown at the moment? I think for the second issue it's enough to get the value of the property of the form:
MyForm.Visible
However, I don't know how I could find out if a form is loaded or not.

Is it possible to run a function or to execute a button just after the form was loaded? I mean to execute it just as the form_load subroutine has ended, so the form is already being displayed.

I have coded in the older version of VB for years (VB6 and prior) and Recently I just began learning VB 2008. In my current project I made a mistake in a form name frmAuthors and so far I am unable to recover. The problem is that I tried to have the form inherit a class I had created (first mistake). The IDE generated a popup message stating the error and provided the option of changing from inheritance from system.windows.forms to the class I had created. I said yes just to see what would happen (I was bored so I was up for something new) and that's when the form got corrupted.Is there a way to let frmAuthors go back to recognizing itself as a form object and not a member of the object I had created?

I have a Parent form that loads a child form and I only want to allow one instance of the child form. I have this on the button to open the form. Stepping through the code with the debugger it "appears" to work OK when the form is open (I say appears because nothing changes) but when the form is closed it doesn't open as I would expect. What am I missing?

I want to dynamically load UserControls with LoadControl which contain their own updatepanels, and when they're on the page, be able to trigger their updates individually via their children.
To explain better, see my extremely simplified example of my issue:
Default.aspx
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">

Ok I have a project which has a MDI parent. Inside the parent I have multiple isntances of a form load(frmLine1t5). When my program loads it will load a different form(frmSelect) and if I manually load a different form(frmRetests) I can put frmSelect on top of frmRetests and bring one another to the front if it's clicked on(without using the bringtofront method)However as soon as I load a single instance of frmLine1t5 I immediately can no longer bring ANY form loaded into the MDI parent(before or after frmLine1t5 has loaded) to the front. I can only bring them to print IF I use .bringtofront method

I have a program I've been working on for some time now and I'd like to try to streamline it somewhat. I have a main menu form that has a split panel, in the left panel is a treeview that displays forms you can open and when one is selected, it opens in a child window in the right panel. Each time I open form I called DWNForm, it does a series of dataset loads which are the populating items for a series of listviews.
What I would like to do is have these datasets load once during the mainMenu load and then have the DWNForm be able to access the datasets once it is called from the treeview selection.

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

I am currently working on an UI form using Visual Studio 2008 - Visual Basic .Net what i find weird is that when i tried to execute my form using the button click function, it doesnt execute until i restart the form.
Here's the situation is like:i have an openfiledialogue [Open button click] to search for a file.After DialogResult.OK is executed, the textfile chosen will then copied to another working directory. The file name will appear onto a textbox1 There will be more than 1 textfile chosen.After all the relevant files are chosen with the file names on textbox1, an OK button click will be clicked to write the file name into a *.bat file.BUT before the OK button is clicked, the user have to select from the radio button which category they want the file name to save into. EG: Country, Cities, Period.Once the radio button is selected and the OK button is clicked, a .bat file will be saved into the working directory.The next move will be the crucial button which is what this UI is created for. A data CRUNCH button is created to execute the .BAT file which was generated earlier on with the [OK buttonclick].The command used

I am learning VB.NET and as a first task I am creating a login form. I've been trying to link it to another form once a correct username and password are entered. However, despite that I still cant be able to hide it or unload it once the next form is loaded.
Here is the Code
Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click
If UsernameTextBox.Text = "chris" And PasswordTextBox.Text = "chrispass" Then
Me.Hide()
Form2.Show()
End If
Me.Close()
End Sub
The Form2 appears as coded above but the 'Me.Hide()' manages to hide the login form but then it appears again.

So just to get better at VB, I'm trying to make this application that takes pictures from your clipboard and uploads them. I'm adding a label, that will tell you if there's anything in your clipboard or not, but the problem with that is that I don't know how to make it check the clipboard all the time.I'm still a beginner, so I only know how to make the app do something when a Form has loaded up, or clicked etc., but how do I make it so it checks the clipboard when it has changed? If I can't do it, how do I make it so it checks the clipboard like maybe every second. Do I need to use threads (I'm not sure, because I don't quite fully understand threads).

I am designing a form that will create a template of data that will later be loaded into another form.From a menu command "Create New Template" I will need to ask how many Fields will be needed for the new template in an input box. If the user would input say 10, then I need to generate 10 labels, 10 text boxes, & 10 combo boxes. Each group (label, Text Box & Combo Box) on its own row on the form.I also want create the data mapping for each of them at this time.Once I have achieved this then I will add a form that will lookup the template name, and row count given from the above form via the database and load the required rows of items for further data entry.
Since I will have a MAX row limit I thought about designing a form using a Table Layout panel with 25 Rows and 5 columns then doing some sort of .visible true/false for the layout panel row after the user input of row/field quantities.Another question is resizing the form around only the visible rows.

the project i am currently working on has a form in it that has quite a few objects that take a couple of seconds to load. Because of that, if i simply use the .show command, the form shows up, but there are a bunch of blank white boxes where the content is still loading, how can i have the form not become visible until ALL of the contents and images inside are fully loaded?
