Can Share Data And Methods With Multiple Threads
Jun 15, 2010I've used mutiple threads in a VB.NET program but I don't know if I did it right.I would like to start about 3 threads.Can they all use the same methods?Will a separate instance of each method automatically be created for each thread?If not, how do you make sure that the data within the method that is used by one thread is not used by another thread?I would like some data to be shared by all threads.How is data shared among threads?What is the protocol for changing the data and checking for changed data?Is there a good tutorial / website that explains how to handle methods and data when using multiple threads?
View 3 RepliesShare Context Menu For Multiple Controls?
Dec 2, 2010This is a conceptual question, so I'm not inluding code yet. I can't understand how to share a context menu strip between controls - how do I know which control the user was in when he right clicked it and made a selection?
Example: I have 3 text boxes that all use the same contextmenustrip and require the exact same functionality so no need to load new options. The user selects one of the options and an event fires something like this:
Private Sub mnuX_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuX.Click
how to determine which text box is responsible for it??

Dec 19, 2011I have a program that are multiple thread. Each thread calculate some data independently. however, they will need share a hashtable which controls a hardware resource. because the resource is limited, so, it may need lock the resource for a thread, and then release it when thread is finished. and the resource can not be reused immediately, will have to wait for some time, say 5 or 10 minutes, for the device to reset.
View 3 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.

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.

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:

But if I start Form2 without Form1 being open, it gives me an exception.
VS 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

Forms :: 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).

View 1 RepliesApplication That Has Multiple Front Ends Developed Using Windows Forms / WPF / ASP / Compact Framework Mobile Forms
Apr 9, 2010I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?
Forms :: Multiple Forms, Closing Events And Sub Routines?
May 25, 2010I have googled high and low to find an answer to this but I must be searching wrong.I have an application which has a listview displaying some items that are stored in a SQL Compact database.

How can I get it to fire the form1 sub routine on the close event of form2
Multiple Forms Program Needs To Open Successive Forms Somehow?
Nov 3, 2009i was doing a fair amount of programming many years ago, like 10 it feels like, so I'm sorely not up to date on how my newly downloaded Visual Basic Express expects me to communicate with it.I am writing a program that pulls a cell from a database after the user has gone through several forms to determine which cells they want. When I write it like that, it doesn't sound very efficient, but I've designed it this way for usability.Here's where I have a problem: Should I store the path the user takes in a string, an array, what?
Here's an example:Someone wants baseball stats and trivia. They run my program, main form pops up, they select National League button, the NL Form pops up. Now the way my program is set up right now, is there are two ListBoxes on the form, one is populated, and as the user selects a Team from ListBox1, it jumps to ListBox2. Once they've selected all the teams they want info for, they click a button Next.
What I now need the program to do is show the next form "Team: name" once for each team, and insert the name of the team on the form in the appropriate label which I'll have blank. This form will also do the Listbox thing except the first listbox will populated with Topics like HR Stats, Pitching Stats, Coach History, etc.
Forms :: Maintaining Multiple Forms Positioning?
Jul 26, 2010Launch a dialogue window from the main form, and then another dialogue window from that dialogue window. If you close the second dialogue window and call dispose the main form vanishes under any other open windows. This doesn't happen by closing a dialogue window normally, but I am attempting (rightly or wrongly) to stop memory useage creeping up by disposing of it.
So, the question is - what method can be employed to maintain the position of the windows?
Forms :: Multiple Forms Open And Close
Apr 16, 2009I have two forms frmMain and frmNew, and one module modMain. In modMain I hold public variables which are needed for application. My question is how to open and close those two forms when needed? I ask this because if i set frmMain as startup form, then when closed, application will end, and one of those two forms will always be displayed. Also if I set frmNew as startup form, then when I close this form, application will also end. Is there a way to do this from module or something so my application won't end after closing and opening any of those two forms?
View 2 RepliesForms :: Retaining Data Across Multiple Forms
Sep 8, 2010VB.NET newbie here... I have an vb.net windows application set up. It has multiple forms, about 6 in all. There's a main menu form, and then 5 other forms to collect data. The user will collect data on each form and bounce back and forth between forms. How do I get the forms to retain the data that has been entered into the text boxes and/or other controls on the forms? For example, they might fill out a few textboxes on a form, but then need to go to a different form and fill something out... and then back to the previous form. Right now, when they come back to the form, all the data previously entered in to the text boxes is gone.

.net - Given A Large Number Of Objects, Create Multiple Forms In Designer For Them Or Use Code To Create The Forms?
Dec 29, 2010If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?
