Use Show Event In Program?
Nov 8, 2011
I try tu use this msdn snipped to execute some code right after my form loads[code]...
But it seems that I am missing something. I get an errormessage that translated sounds like this:
The Handle requiere an WithEvents-Variable, which is defined in the contained type or its basis class... My Form is named Form1 so that should be ok. the error is marked in the second line of the code.

Normally I just redirect to a custom error page in on the Application_Error event, but I have a specific error for which I'd like to display an alert message while the user is still on the page which triggers the error. How can I make this happen?
I'm open to a modalpopup or any other type of error message, I just want to ensure the user stays on the page where they encounter the error.
This is in reference to this thread: [URL]
Here is the code I'm currently using:
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
'Code that runs when an unhandled error occurs

I'm trying to show message "Loading..." when a user select an item in the dorp down list.
Mark up:
<asp:Label ID="lbl_LoadingMessage" runat="server" ></asp:Label>
<asp:DropDownList ID="ddl_Chapter" runat="server" AutoPostBack="True">
</asp:DropDownList>
[Code]....
The method I'm using above is not working. When I select a new item from the drop down list, it works as expected except the message "Loading..." is not showing at all.

Currently have created/extended the DomainUpDown class hoping I would be able to add one simple feature: I was hoping to be able to show a tooltip when the user mouses over the control that would show the next and previous item in the list. However the DomainUpDown class does not have a mouseenter event and overriding the mouseenter method does not seem functional. Is there something I am missing or do I just need to create my own MouseEnter event?
Private tips As New ToolTip With {.AutomaticDelay = 0, .AutoPopDelay = 0, .InitialDelay = 0, .ShowAlways = True, .ForeColor = Color.WhiteSmoke, .BackColor = Color.Black}
Protected Overrides Sub OnMouseEnter(ByVal e As System.EventArgs)
MyBase.OnMouseEnter(e)
Console.WriteLine("list entered") 'testing purposes, never is printed on mouse enter
tips.SetToolTip(Me, "Up = " & Me.Items(Me.SelectedIndex - 1).ToString & vbLf & "Down = " & Me.Items(Me.SelectedIndex + 1).ToString)
End Sub

I need to trigger an event (clear some text boxes) when I click on the "ok" button in the MessageBox. Below is the event triggered messagebox code. A box pops up with the included text and an "OK" button. The program appears at this point to stop and wait for the click on "OK" MessageBox.Show("Check -Sender Information-data")

whats the quickest and least application hogging way to retrieve image from web and show in picturebox on listview selection event?
Heres the code i have already which produces app lag for abut 3-5 seconds per image loaded, i think as it stretches the image to fit into picturebox (which is needed)
vb Private Sub bwGetScreen_RunWorkerCompleted(ByVal sender As System.Object, ByVal e As System.ComponentModel.RunWorkerCompletedEventArgs) Handles bwGetScreen.RunWorkerCompleted
For l As Integer = 0 To ListView2.Items.Count - 1 'start download selected If ListView2.Items(l).Selected = True Then Dim fileid As String = ListView2.Items(l).SubItems(5).Text.ToLower Dim recordid As String = ListView2.Items(l).SubItems(6).Text.ToLower + 1 urlpic = "http://se-board.com/index.php?app=downloads&module=display§ion=screenshot&full=1&id=" & fileid.ToString() & "&record=" & recordid.ToString()

I am struggling with this issue for serveral days now.My application needs to work like wsus (windows updates) does. On a certain event triggered by a windows service working under SYSTEM account it needs to show a (second) form under the user context.The IPC Remoting works fine so I think my issue is in the threading.When I use form2.Show() form2 appears but the form freezes.When I use form2.ShowDialog() the form appears but I cannot get the focus on it.
Service running under system account (in this example a simple console application)
Code:Imports ClassLibrary1Module Serv
Sub Main() Dim SDSIPC As Semaphore = CType(Activator.GetObject (GetType(ClientFromServer), "ipc://Client/SreeniRemoteObj"), Semaphore)
SDSIPC.DoSomething()

I tried to make a menu for my game, but when I placed the code into the form loading event, it wouldn't show. Then I placed a button and moved the code into the button click event and it worked. Thus, I know the code shouldn't be wrong. How can you make the graphics( as in lines, rectangle,etc) show up when it starts up?

Given this illustration and basic code, how do I dequeue and draw the data that has been inserted into the User Control's Preperty queue? The graph/chart will need to show anywhere from 1 to 120 seconds of data, with each second representing electrical waveform data that arrives each second with a variable amount of sample data..The timer interval will have to vary with the amount of incoming data so that it shows a continuously moving waveform from right to left and the rate of drawing keeps up with the amount of data arriving. (so the queue doesn't get backed up)

I have designed a program that, when the "caclulate" button (btnCalc) is pressed, it asks the user for a file name, then pulls data from that file (file is a .txt of 100 decimals, one per line) and displays the Total, Average, Highest and Lowest. To do this, I have placed all the data into an array, and then used the array to get the information I need. All the code is in place, the only issue is that when the "calculate" button is pressed and the file name is entered, nothing happens.Need to figure out why the values are not displaying in my 4 labels (lblTotal, lblAverage, lblHighest, lblLowest)!!Here is the code:
Imports
System.IO
Public
[code]....
(For the record, I know I could get the data in one pass, however, being a beginner, I like seeing each value computed separately.)

I'm currently trying to create a program that includes a text box (to input a number into), a button and a list box that will display the times tables for the number that is entered into the text box.
The idea of the program is so that a user can enter a number into the text box, for example, the number 5 and all the times tables (up to 12) will be displayed[code]...

but I am trying out VB.net and is trying to make a program to show the ascii code for every key press I made.. here is the coding i used..
Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As _ System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
TextBox2.Text = e.KeyValue
End Sub
this one seems to work fine, but I noticed that regardless of whether I use "A" or "a", the ascii code shown is always 65. last i checked small letters have their own ascii code, so "a" should show a ascii of 97, not 65..

Alright, so what I'm looking to do is make a dock or some other thing that I can hide/show for programs. Kind of like a shortcut holder. how to approach the issue. I'm thinking maybe I could make a new button based on some settings in the VB thing, but that seems rather inconvenient. I was also wondering if anybody knew how to get the icons from shortcuts or the rest to use those as display pictures. "Victory is difficult to see beyond the devestation incurred in its pursuit."
