View 12 RepliesI 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.

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

Using 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

I am using vb express 2010.
Below is the code that i use to call up a new form. I wish to pass the variable 'connstr' into frmRace.
Public Function ShowRaceForm(ByVal userName As String, ByVal connStr As String) As Form
Dim frmRace As New RaceForm
Return frmRace
End Function
I have two forms with a variable (x) that is set by a trackbar on the second form.
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.
View 6 RepliesMy problem is that is have 4 forms, 3 of these forms allow me to pass variables between them.. however one form the Booking form won't allow me to pass the txtTotal variable to the Confirmation Form.
All the other forms all me to do this, im not doing anything different i can see... im thinking that perhaps another part of the form is prohibiting me from passing that txtTotal to the Confirmatin form.[code]...

how could i able the value into combobox from independent form into child form...
I'm trying to program in a true object oriented manner and its causing me to re-learn a few things. Specifically, I'm having some trouble with error handling. I have all of my data access being performed by an adapter class in a seperate project. I can catch duplicate records without any problems, but I want to be able to send a message back to the user. Here's what I have so far:

I have one form Form1, which opens another form Form2 from within one of its procedures.Now Form2 needs to do some processing of data, and populate a list. The user selects a value in this listthe value back to the already open Form1 (not to a new instance of Form1). How do I accomplish this?I think I will need to define and raise events for this, but I don't know how to go about it.

View 3 RepliesWhen working with a collection of forms that the user must step through, is it better to pass the data foward when creating a new instance of that form, or is it better to call a function from the previous form? I have some code written that calls the previous routine, and it looks ugly, and I can't quite think of a reason why it was done that way. The only reason I could come up with was if the data was large, and there was a good chance that the user wouldn't use the data except in a special case.
View 7 RepliesI want to move a viriable content from one form to the other . and like wise. Lets see now here is the startup form.
Public Class startup
ok as you can see am making a public shared variable to get the name from the textbox and put it in the var, thats easy already done , now the problem I can't get it to be moved to the other form. (Below the 1st code is the code I use to get the outcome from form1 to form2).
Public Shared playername As String
Private Sub startup_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub

What I want to do is either trivial, or likely impossible in the .NET framework.
I have a number of forms, with various pictureboxes, labels, etc. in each. Same names for the same items on each form. Only one form is visible at a time. What I need is some way to assign to a variable in the code which form is currently in use, such that I can reference the control on that form in a single statement.
That is, I have set up (already) references to the individual forms (call them frmForm1, frmForm2, etc.). So I can write to a textbox as:
frmForm1.textbox1.text="Hi there."
frmForm2.textbox1.text="Hello world."
What I need to be able to do is something like:
currentform = frmForm2
currentform.textbox1.text="Display on visible box"
Is such a thing even possible? Obviously, the way .Net normally wants to work is to verify everything at compile, and there is (of course) no way for it to know if whatever "currentform" points to even has a "textbox1" control.
save me a LOT of long-winded IF-THEN-ELSE to see which form is currently displayed for each and every time I want to display something. [FWIW, I *could* right everything out to every form, but I feel that would waste to much CPU time.]
Is the StartUp form of a program saved in a variable (i.e. from the name space My) ? I guess I can catch it during startup by using an Object Type variable during Load time , but I wonder if it is already defined anywhere else .
