I have a list in detail view that (obviously) lists information. I want to edit an Item if it is double-clicked on. I'm not sure what the best way to do this is. Currently I have this:
Private Sub SoundList_DoubleClick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SoundList.DoubleClick
index = SoundList.Items.Item(SoundList.FocusedItem.Index).Index

I have one form, which the user enters upto 5 websites then clicks go - I have on the second form, the one with the webbrowser. timer which checks if the web browser is busy then either a green light or black image will be shown along side the assocaited input box on the first form. I am finding it impossible to feed variables into the clock through ByVal, like I would a subroutine or function.
[Code]...
Is it possible to pass a variable set in one form to another?
View 12 RepliesUsing Visual Basic 2008 Express. I need to pass a variable to another form. Or else make the variable visible to both forms.

If ((WebBrowser1.IsBusy)) Then
Hey.BackColor = Color.Black[code]....
'Error message says Hey is not declared, as i can't pass it through to timer
The variable Hey is determined by the first form - Which picturebox.I have an if statement which simply says if inputbox one has url enter then Hey = Picturebox1, If input box2 has url entered then Hey= Picturebox2 etc.What I want is the timer to check the page has completed loading or is still loading or refresing and the appropriate green or black to be shown aside url input box on first form.I considered using a sub or procedure to act as a clock (a large for loop with another for loop within it, acting as a delay). But found this slowed down theapp to the point of crashing it.
I want to pass variables from one form to an other. The variables i I need in the second form( called" Hulsview") are :" hulsbreedte" and" hulslengte". To check if the varibles are passed I added a textbox in the second form,called" hulsview" to check the variable" hulsbreedte". The value selected in the combobox on on form1" hulsbreedte = HulsBreedte1.SelectedValue" returns always 0 in the textbox on de second form.
Here is the code form1:
Imports System.Drawing.Drawing2D
Public Class Form1
Inherits System.Windows.Forms.Form
Public hlb As Point 'not used

View 3 RepliesSo I'm pretty new to operating in the VB.NET environment, so this might be really basic. But my issue is this. I am writing an application to get the next available computer name within active directory. I have an VB program that queries active directory and finds the next available name. I also have a VB form that will allow you to set the name of the computer and which Active Directory OU it should go into. I would like to have the program that finds the next available name run right away when the app is opened, and then pre-populate the computer name field in the VB form with the next available name from Active Directory. However I'm having a very difficult time finding how to do this. I've tried adding the first program in the ApplicationEvents startup area, but I'm not sure that it's running, and I can't find how to programatically pass the result from the first program into a textbox field.
