Forms :: How To Manage Several Forms
Nov 17, 2011
I am a beginner to vb. So I am doing so many efforts to write some programs myself. The first thing that I have found difficult to manage is when a program has several forms. Basically what I do is just hiding one and showing up the other form. it does not look that nice. I was thinking of having one form and laying all the other forms on that one. Let me explain myself more thoroughly. Let's say to the left hand side of my form, i have few group boxes with buttons. So when clicking a button, it should automatically close the form and show up the new one on the main form. Its like refreshing the form. So what I mean is that there is only one main form and clicking each button will show another form. Hope I am explaining myself correctly. I have tried MDI but that's not I am looking for. Some friends have told me to use user controls. Is that the correct path to follow?

I would like to know how do .net developers manage a large window application with a large number of controls, such as textbox , button, groupbox? I have seen a number of people do it this way : declare the controls as an array and initialize them one by one at run time . In this way it is easy to manage those controls because they can be accessed by array index; but this solution seems to require very good understanding of control's attribute such as its location, font etc. This could be a difficult task if the project is passed on to a less experienced developer and add changes to it.How do you deal with it?

I have a basic three form application. It doesn't seem to close after navigating through forms. If I were to open the application, and the main form is displayed. If I press the X button, the application closes fine(Goes from processes) If I were to open the application, and then navigate from the main form to another form using me.hide & form1.show, and press the red X on Form1, the application again, closes fine.

I 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?

We have an application that has a main form with a map on it. Right now the paradigm is to have forms that are displayed using menu items to display information to the user. Most of these forms are modal forms, but a couple are non-modal forms that interact with the map. For some of the forms, it really would make for a better user experience if we could dock them in the main form of the app and allow the user to see both the form and the map. For instance. We could have a list of map features in a docked window, and select one of the items on the list and have the map zoom to that feature. Or do the reverse: let the users select a map item and have a docked window that shows details of the feature. Sounds great, but I wonder about what sort of gotchas we may encounter. In particular, what if we have two windows docked at the same time? Could we get tangled up in our event code?

Passing data between forms without any public methods or properties on the forms. everything but the "Controller" class, which I would like you furnish. I just changed the title from "Intermediate" to "Beginner" This solution is an example of the Observer Pattern. The "Controller" class is the "observed" class, which in this case means it publishes events.
' File Definitions.vb
Public Delegate Sub MessageDelegate(ByVal sender As Object, ByVal e As MessageEventArgs)
Public Class MessageEventArgs : Inherits EventArgs
Public Message As String

The program should initially display Form1, and Form2. Clicking of the button on either form will modify the Title Text of both forms. I think that you will find the final end result to be pretty neat, as it works with any number of open forms not just two. I think asking for the Controller class is easier than asking for the code in the forms. My solution for Controller class has 7 lines of content, 9 lines if you include Class, EndClass. A minimal solution could achieved with only 4 lines of content, but it would a textbook example of bad programming.

I'm looking forward to reading and adding more to the community here. I've created a text based rpg. Next semester we are learning Visual Basic. I'm on winter break and I would like to get a head start on my learning. I've been working on creating some forms and message boxes. What is throwing me off, is that I have a good feel for doing coding so that I get functionality the will produce effects in a console. Coding the forms is a bit confusing for me. Is this something that others have run into? Is their some good primers for VB? I don't have my text books yet.

I build my first Project composed of several forms and it�s working just fine. Id like now to redesign the project as a MDI Application. Once created the parent form, I can create child forms but thats not what I need. What I would need is convert my already designed and working forms to MDI child forms. How can that be done?

I have no idea what I have done wrong here, so I'll just attach my project as a zip file and see if any of you are kind enough to look into it for me.I am reasonably experienced in C#.NET but having trouble using VB.NET for a school assignment.I cannot open half of my forms in designer view because "To prevent possible data loss before loading the designer, the following errors must be resolved".

I was playing a game recently and saw that they could use args in the shortcut, and I decided to try to impliment this into my application...so far, I got: (runs this sub on load)
Sub startup_args()
If Environment.GetCommandLineArgs.Contains("+game") Then
Dim path As Array = Environment.GetCommandLineArgs
[code]....
just to see what it returns, but the application crashes. I also tried path.tostring(), but that didn't work. When I did:
If Evnironment.GetCommandLineArgs.Contains("+game") Then
Dim path as string = Environment.GetCommandLineArgs.tostring
MsgBox(path)
[code]....
but that returned the value "SString.Array[]"...

I 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. I am using a second form to add new items to this list directly into the database.When the second form closes I want to call the sub in my first form to refresh the list from the database.
How can I get it to fire the form1 sub routine on the close event of form2

i 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.

My question is, am I able to share a business logic layer seemlessly between the two presentation layers or is there anything I need to watch out for. I'd really like to not have any duplication of business logic, so any advice would be more than welcome.

i have a problem with trying to get 2 forms to close at different times using a timer on each of the 2 forms.
This is my form layout:
Quote:
frmMain
Frm1
Frm2
Frm1 and Frm2 are identical to each other. FrmMain has 2 buttons on it. One button to call Frm1 and the other to call Frm2.Frm1 and Frm2 each has a timer. It counts down to 0 and then does a .close(). However, if i pause between clicking the second button they both seem to always disappears at the same time.I would do something like this...
Click on the first button (showing the Frm1 form)
wait about 10 secs...Click on the second button (showing the Frm2 form)they both are shown on screen...hen they both disappear at the same time.... which shouldn't happen since i clicked the Frm2 box 10 seconds AFTER Frm1... So Frm1 should hide before Frm2 does...but it does not.

I have made a project on Library management system using Microsoft Visual Studio 2008 and Sql server 2005 .I have used MDiParent form in this project, from where I can click on the menu item to open the desired form.
I am now able to open the child forms in the main window background.Now what happens is When I click on one menu Item it open in the parent form background.I am able to open all child forms corresponding to the click event in the MenuToolStrip ...all in the Parent form Now the problem is that I cannot minimize child forms when I minimize Parent form..I want child forms also to minimize along with the Parent form.. Also are child forms still not attached to the parent Form is also my question here.....
