Alright, so I need a method that traverses all the forms inside a VB.net project under Visual Studio 2008, and create an array of type form with references to all the forms inside it, so that the array looks like this (pseudocode)
FormsArray() = [Form1, Form2, Form3, Form4]
However, I don't have a clue as to how to begin.

View 2 RepliesBasically I want to find the first occurrence of one array in another. I have tried using the Array.IndexOf Function, but it always returns -1. Example:
Dim array1 As Byte() = {1, 2, 3, 4, 5}
Dim array2 As Byte() = {2, 3}
MsgBox(Array.IndexOf(array1, array2))
Even though array2 does exist in array1, the message box always shows -1

View 3 RepliesI am trying to populate an array from a listbox.My listbox items contain something like this:
1 for January
10 for February
3 for March
I have code in place and it was working, but I am taking the first character of the listbox item to populate the array. If the value of the listbox is 10 for February, I need to get 10, not just 1. Can I do something with the string that says I want to trim everything from the space to the end? Since they are all formatted the same way, if I could trim out anything from the space on, that would work.
Here's what I currently have:

What would the process be to do this, would i need to create a reference list or stringbuilder for all the tags(there is about 3000 tags) or would it be possible to loop through and count the matches. I declared the Tags thinking that i could do something from there.

I have a project with several forms and modules. The problem which I am mentioning revolves around 3 items : 2 forms (e.g. form1 & form2) and a module. (Using VB.NET 2008, .net 3.5)
Now I have a structure declared in a module. I have a variable of that in form1 and form2.
'Module Code
Structure MScanner
Dim Indicator() As MuseIndStru
Dim FName As String
[CODE]..............
Now what is happening is, I am passing structure variable MScan (Form1) to Form2 (see function of form2 InitFilter) byvalue. Then in form2 I am changing value of a copy of the structure (see variable MS being changed in a private sub). But then when I close form2, form1's variable of MScan also get the value of variable MS (declared in form2).
I don't understand as this is not suppose to happen. I have reloaded my project as well but this problem is there. Why is my form1's variable value MScan being changed by form2.
I am fairly new to VisualBasic .NET (2008). I'm creating an application that, when a number is entered into the textbox, a new form window is created and populated with buttons. Each button starts the same command, but with a different parameter (the parameter being the pertinent record number found by the search).'The records are asset tag numbers.The procedure works fine if there is only one result.But the search allows for partial numbers and that's where the trouble begins.If two or more results are found, each button is configured with the last number found. The button being clicked doesn't tally with the proper ID number.[code]
What I didn't count on was that the event is only called when a button is clicked. When buttons are made, they are not assigned at that time.I've had problems trying to carry over the (current value) for pcArray(i), hence having it populate that form3_text field. When trying to add in a second object to be passed, I get the following error:"Method prtivate sub DynamicClick(sender as object, pcNameInfo as object, e as system.eventargs) does not have a signature compatible with delegate sub event handler with delegate 'delegate sub eventhandler(sender as object e as system.eventargs)."I tried manually entering a "Delegate sub eventhander" with the pcNameInfo object and VB 2008 ignores it.What can I do to get each newly made button to be told to run the RemoteIn(pcArray(i)) process properly?

MsgBox(serialports(4).PortName) ' this retuns the value COM4
