I declare an array on one form that i'd like to use on another form. I declare it public in the declarations area and edit it later within a Private sub. However, when i reference it from another form it's as if i haven't editted it at all and it is only grabbing the initial declaration.

I am in college taking computer programming and we are now in multiple classes and forms. It was very hard to get ahold of at first but now that I understand it a bit better I am curious as to how often in a professional enviornment do developers create multiple classes for a project? Besides the use of custom functions what else is beneficial for it?
View 4 RepliesI 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 have a project that I have created, it something like a contact database.It is complete with its own sql server database, and controls and forms.I kinda of understand that I can include this project into another project.This is the tricky part,Can I include my contact project into another project and add more items to the database and forms in a new project?What I'm after is like using classes.My contact database would be like the base class, and the new project would be adding more features to that project.

View 7 RepliesA colleague has written a useful tool. He wrote it as a standalone tool, but it works even better as an includable dll, though it needs a bit of other functionality for it to be a really good drop-in component. What I am wondering is whether a project can be compiled as both an exe and as a dll?
There are alternatives, such as having a dll version and an exe version, since the dll version needs to include a few different methods that the exe version doesn't need, but this alternative sucks, since it would mean changing two sets of code.
Another alternative is to build the dll, then change the exe to be a project that references the dll....and does nothing other than calling one method in the dll. That kind of sucks, too, but not as bad.
I want to be able to use his module in some of my programs, and it really should be built as a component rather than a standalone app, but I want to know whether there are other options that I haven't considered.
What is the vb.net equivalent to accomplishing this?

The code shown below works fine. I run it from the project SQLtesting. It loads a listbox and a checkedlistbox with the controls found on a form. I can change the value of the FormName field to any form within the SQLtesting project and get the form's controls. The forms are not actually opened/shown.I would like to be able to access forms in other projects i.e.

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?
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.
I have a one-dimensional array that has one number per element. I also have a variable number, var. I need to take the number of elements from the first array that equals the var and put it into a second array with commas between the numbers. I would also like to have a title element in the second array. [Code]
View 4 RepliesLaunch 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?
I 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 RepliesVB.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.

I'm still learning vb.net, so I'm not terribly familiar with all the terminology, otherwise I would have searched a little harder before posting. I'm working on a program where the user can add various forms to a MDI parent.I would like each of the child forms to be part of the same array, all of the child forms will be of various types.Some forms may display a textbox, some forms may contain a graph, some forms may contain an image, etc.[code]

View 3 RepliesIf 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?
I have a windows forms application developed in vb.net 2008 (WBLoad) that opens and loads an Excel 2010 workbook (xlAnalysis.xlsm). The xlAnalysis.xlsm is included in the project WBLoad and is loaded from the application folder which is on the user's C: drive.
The wbLoad.Application and associated files are deployed to several network servers across the company.I just created a custom action pane using vb.net 2010 and added it to xlAnalysis.xlsm. The question is how to I include the workbook with the action pane in the WBLoad project?

View 8 RepliesMy project will be a collection of 3 projects that have similar GUI's and call on common assemblies. I want my project to contain 3 executable files when published that will load one of the designated smaller projects. Each of the smaller projects is designed to perform a different task, yet they are all similar in terms of looks and how the user interacts with the program. The best way to picture it would be MS Office. All the office programs (excel, word etc..) are part of the same package, and look similar but they perform different tasks. You can load any of these programs by opening the relevant .exe file, which is exactly what i want to do with my application.

View 3 RepliesI am trying to create a deployment project for a solution of many projects and two start-up projects. I understand that there are 2 primary outputs in this case. The solution will not work/make sense if either of the two outputs is not running.
At the moment, I have created a set-up project with the multiple outputs, but then I will have to open the outputs individually for them to work. I am wondering if there is a way to create a desktop icon that targets both outputs simultaenoulsy.
