How To Share Variables Between Forms
Feb 17, 2012Is it possible to share subscripted variables and their data between forms? So far I can't see the variables I made public in one form, in a second form.

Share Variables With Other Forms?
Mar 6, 2010Say I have public string variable called "_Test" on Form1, how can I allow Form2 to edit/read the variable from that form? I tried putting this on Form2:
Public _Test as String = Form1._Test
But if I start Form2 without Form1 being open, it gives me an exception.

View 4 RepliesHow To Share DataSet Among Two Forms
Jan 13, 2009I'm new to VB2008 and SQL Server. I have two forms (frmCustomer and frmDetail). The frmCustomer has a datagridview containing general data of customers, and a button to open frmDetail, which contains each customers detail information. All data modification is done on frmDetail (add, delete, and edit). Currently, both forms are binded to the dataset (same table). When the two forms are loaded, each form performs a FILL function that retrieves the data from SQL Server. In addition, all modifications done on frmDetail does not show up on frmCustomer until I perform the FILL function again on both forms. Seems like I'm maintaining 2 sets of data from the same table, and I think I'm doing more work than I have to. I'm sure there are ways to make this easier, such as bind both forms to a single dataset, so I don't have to do everything twice.
View 1 RepliesShare Forms Between Projects?
Dec 19, 2009I've recently noticed that a solution can contain multiple projects. I'd like to know if I can create a form that exists in multiple projects, so i can edit one form (or class) instead of six, and have it published in each one of them separately? I hope that makes sense....I seek not answers, but understanding, that I may not solve, but learn.

View 3 RepliesVS 2010 Share A Menu Bar Between Two Forms?
Jun 17, 2010I'm writing a small software similar to the calculator in Windows, the calculator in Windows has a menu bar; in the menu bar, you can find "scientific" and "standard" mode; once you select different mode, your form will be changed, but the two forms still share the same menu bar.
I want to create the same effect of this:
1. Two forms, only one is visible at any time
2. The menu bar on the top of the two forms should be shared between these forms
I just started learning VB for 2 weeks, I'm not sure my thinking can be achieved by VB, if not

View 6 RepliesForms :: Share Data Between Forms (as Opposed To Passing Data)
Nov 26, 2011Quite a few threads on passing data from one form to another, but I'm struggling to work out how to share data between the two - back and forth.
For example:
Class1 is a class with 10 string properties
Form1 has 10 labels ("Label1", "Label2" etc) and a [Configure] button.
Form2 has 10 textboxes and a [Apply] button.
I want to load with Form1, and create an instance of Class1. Click the Configure button and load Form2, passing Class1. On Form2 I want to manually fill in the 10 textboxes and hit Apply. The Apply should update the Class1 instance and close the form.
Form1's Label controls should then be updated with the data from the Class1 instance.
I'm fine creating the forms and classes, as well as passing the class into Form2 with a custom Sub New(EmptyClass as Class1) constructor. This gets the empty class into Form2, but how can I get the populated class back to Form1?
As Form1 already exists I don't want to create a new instance with another custom Sub New(PopulatedClass as Class1)
It's also key to be able to use the Form2 multiple times, basically ending up with a Data class being displayed as part of Form1 but updated using Form2? (For example if the Class has already been created and populated with data when it's passed back to Form2 for the second time I would pre-load the Textboxes with the values already in the class).
Forms :: Passing Variables Between Forms
Nov 27, 2009I seem to be running into an issue. This may seem like a noob question (which it really is, I only have experience in vb6 from years ago) but what Im trying to do is pass a variable from one form to another. Ive tried telling the first form to set the value of the variable on the second form like so frmsecond.variable = "value" but that does not work. Ive tried placing a public variable in a module to do it, but again, no luck. The only way seem to be able to get it to work is the second form setting the variable by reading the value from the first form like so [code]The problem I have with that code is what if for some reason the selected line gets changed as the form is loading or something to that nature. It doesnt seem very secure.

How To Pass Variables Between Forms
Sep 6, 2009I am having trouble passing variables between forms. Ive tried many methods but none seem to work. The first method I tried was to dim a public variable on the first form and call it on the second....no success

cliCode = me.tbClientcCode.text
Form 2:
dim clientCode as string = form1.clicode

Multiple Forms, Variables And So On?
Oct 24, 2011i would like to say i am a novice programmer, in year 12. I am designing a small game for my HSC and one of my forms is getting very cluttered with controls and code. To resolve this cluttering, i have had the idea to create new forms for some aspects of the game (such as different game modes and so on). However, in order for that to happen i have to drag some variables of the new form to the old form, (these variables would be just booleans or integers to say whether you lost a game or won a game or something that would carry on to the main form.)

Best Practice For Sharing Variables Across Forms?
Mar 27, 2011I need to share variables across two forms in vb.net. One of them is the main form and the other is a child form.
Create a static/shared variable in one of the forms and access it in the other forms via:
Form1 frm = new Form1(); //creating object of parent to access shared variable
frm.a = "abc"; // passing value
Send an instance of the main form to the child form when creating the child form. The variables can then be accessed via a property function. Create global variables in a module. This seems like the easiest option, but I doubt it is the best option.I also read something about delegates and events, but I don't know how to implement this.

Forms :: Passing Variables To Timers?
Sep 28, 2011I have a form that holds min two timers, One is a 72 hour timer and one is a 12 hour timer.
What I am trying to do is have both run at the same time, when the 12 hour timer expires it'll bring up a form informing the user that in 60 hours the machine will reboot (or they can just hit reboot). When the 72 hour timer expires it reboots the machine.
BUT I know my managment is going to want to be flexable. e.g instead of 72 hours make is 54, and instead of 12 make it 6.
I wish to avoid using global variables
This is the code for the 12 hour one, How do I call it and set i12sec and i12min?
************************************************
Private Sub t12hTimer_Tick(sender As System.Object, e As System.EventArgs, i12sec As Integer, i12min As Integer) Handles t12hTimer.Tick
t12hTimer.Interval = 1000 '1000 Miliseconds = 1 second
