Make The App Do Something When A Form Has Loaded Up, Or Clicked?
Nov 4, 2011
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).

Basically i want to be able to click a button on the form, and the buttonclick event occurs, but the current window retains focus. How can I do that?

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.

I 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
End Sub
[CODE]............................

I'm trying to make a list of flight plans loaded into my program, with each flight plan having a list of waypoints along the route, along with a few other properties associated with the flight plan. Each waypoint has its own associated properties, i.e. waypoint ID, waypoint type, location, etc.
Here's the declarations:
Code:
Public Class WPinfo
Public WPType As String
Public WPID As String
[Code]...
How do I implement the List methods to access the list elements, and add, remove, etc? The way I'm doing it now just gets me an 'Object reference not set to an instance of an object' error during runtime.

I'm working on a VB.Net windows application.In the top half of the form application, I have a vendor number with a "GO" button and in the bottom half I have a list of tab pages. We have built the application to only go to the database and display data when the tab page is selected by the user. If I'm in one of the tab pages, and I change the vendor number and click the GO button, the data on the current tab page goes blank (it does not refresh). I have been told that I have to find a way of programmatically clicking on the tab page's tab a second time. How do I do that? I've tried using _Selected event, _Selecting event, _Click event. I've even tried to do a .Focus() on the tab page itself. Nothing seems to work to reload the new data without clicking off of the tab and back onto it manually.

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.
