Ok im failing at this. Im trying to get all my forms on one project to read my Module. I need them all to read because of the way im building it. Im trying this code but it dosent seem to be working.
[Code]...
Y can i not link my form and button type of that form to that code? Do i need to use a differnt Sub or what?
Im running a program with multiple forms with a menu and toolstrip defined and assigned with properties in a module. each form has the Call menuload (Me) in the form_load sub.
My problem is that these menu's have menuitems which need close the shown form and open another. a sample of one of my menuitems is:
Module MenuTemplate
Friend WithEvents frm As Form
Friend WithEvents menustrip As New MenuStrip
[Code].....
I declared the variables with in the first module to be loaded
Module Mod_Global Public DtFRM As String Public DTTo As String I can load the variable and read it with in the module. Ok, good so far. But sending the code to another module results in nothing in the variable.
I'm trying to declare a array that I want to use in the module and in the forms. I like it to be usable all over but I cant get it to work.I tried this code but when I want to use it in the module it says that it isn't declared.
Code:Public Class Form1 Public ShuffleArray() As String Anyone know what I should do to make it work?
Define a structure named product, The structure should contain 2 variables one as a string and the other as a decimal. The decimal is used to store the price and the string is used to store the item number.
Declare a module level array that contains 5 product structure variables
Code the main forms load event procedure so that it reads the item number and prices from the itemInfo.txt file The procedure should store the item numbers and prices in the module level array. It also should add the item numbers to the list box.
When the user selects an item in the list box the items price should appear in the xPriceLabel. code the appropriate procedure.
The code I have is as follows
' Project name: Glovers Project
' Project purpose: The project displays the price of an item.
' Created/revised: <your name> on <current date>
[Code].....
Seems the problem I am having is this line is returning a value less than 0.
itemprice = (itemnumber.Substring(productIndex, newLineIndex - productIndex))

I 'm a beginner and have a project that I'm using to turn lights on and off. I need to use separate forms for display on remote monitors. My problem is each form needs the same serial port open to work and the port won't open unless it's closed in the previous form. Using a module works for opening and closing the port, but only for one round. If I try to revisit a form I already accessed it doesn't work.
Public Sub sp1(byval SerialPort1)If Form2.SerialPort1.IsOpen = TrueThen Form1.SerialPort1.Close() If Form3.SerialPort1.IsOpen = TrueThen Form3.SerialPort1.Close() Form1.SerialPort1.Open() end sub
Public Sub sp2(byval SerialPort1) If Form1.SerialPort1.IsOpen = TrueThen Form1.SerialPort1.Close() If Form3.SerialPort1.IsOpen = TrueThen Form3.SerialPort1.Close() Form2.SerialPort1.Open() EndSub
Public Sub sp3(byval SerialPort1) If Form1.SerialPort1.IsOpen = TrueThen Form1.SerialPort1.Close() If Form2.SerialPort1.IsOpen = TrueThen Form3.SerialPort1.Close() Form2.SerialPort1.Open() EndSub
end Module

View 2 Repliesthe project uses a submain as startup object which is located in a module, thy so the application will be started in tray. Within the main() event i need to deserialize a xml file and with it set the properties of a class and then set what the application will do.The problem is, after I deserialize it and put set the property values I try to get them in the same event(main) but when it gets the value it returns as nothing(if string) or 0(if integer) but in the debugging i saw it setting the values. Is there a way to do that, within the main() event of a module to set the properties of a class and then get them without being nothing/0 ?

I was a vb6 user, done a few projects only with forums Now i am moving to vb.net(vb2010) and i have some trouble.Lets say we have a form(form1), a module(mod1) and a textbox on the form1.

Stream Type: MPEG2 Program
Profile: main@main
Frame Size: 720x480
Display Size: 720x480

and have the values entered into form controls so I can add/update them in my database.For instance, read the line "Stream Type: MPEG2 Program" and only add "MPEG2 Program" into a textbox or combobox, the line "Frame Size: 720x480" into height and width textboxes and so on.I can read the entire file into a textbox, but I need to separate the values to enter into a database.
I would like to know how can I use (read and write) a value in each of my forms. To make it clear: I have 2 forms, Form1 and Form2. I've a string, called string1. If I use in Class Form1 (e.g. at Form1 load) Dim String1 As String, Form2 can't read or change it, because it only exists in Form1. So I would like to have a, let say "general value", a (for example) string, which every form can read&write.
