I want to create a variable to be used by multiple forms, so I created a module that looks like this:[code]I expected the title of that specific form to be "(Name)'s Settings"But instead, it just says "'s Settings," as if the variable had never been assigned a value.
View 4 RepliesI have a problem with my program. I wanted to know how i can make a global variable like an integer be recognised in any form so in essence linking to two forms together. Also how do I store an integer that has been typed by the user into the textbox? This integer will then be stored in the global variable. I have got two forms, one is for the user to interact with and the other is going to be used for displaying the global variable.

View 4 RepliesI have a VBA form in Microstation I am using to try and help automate a task. The only problem I am having is I am reading a textbox (Filebox.Text) and setting it as the variable (FN). It works, because I used Msg.Box (FN) to test it. However, in two of the lines of code, I am trying to use (FN) to pass the typed in filename to the command to run in Microstation. Unfortunently, it gets passed on as (FN).dgn instead of the actual filenale typed into the textbox. Is there a way I can make the variable actually seen as a variable? Code on Pastebin: url....Also, not sure if this is the right section, 100% new to VBA, coming from a world Bashed together.

other than GML (Yoyogames.com Game Maker Language), I am new to the coding world. The only "major" project I have completed using VB is a computer calculator that exactly mimics the capabilities of Windows 7's calculator. Yesterday, I began a Chatbot program for my girlfriend. Lol. I have used the instr() function to answer most of the questions or answers which are typed into the textbox1. I find this extremely troublesome because when using the instr() function you cannot say instr(textbox1.

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.
Launch 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.

In my attempt below currmiles is simply being displayed in both labels instead of _currmiles to Currmiles.Text and _currdays to Currdays.Text.

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 file which is opened and the bytes are loaded into a class.The file needs to be split into chunks, and there is a header which gives the locations and sizes of the chunks.Should I (upon opening the file) split the file into chunk sand store each chunk in an array of variables And then when I want to access the data in the chunks I just use the array.
or store all the chunks in one variable together and then when I need access to the chunks get the location and size of them and use that to find chunks each time I need to modify them.

View 7 RepliesI have a listview box. I load the listview up from a text file and everything is divided into three groups. I need to be able to select multiple lines then push that out to a single variable, separated by commas. Two things are happening that are problematic:
1) If I just have it set to smallicons and no checkboxes, anything I select is highlighted right up until the control loses focus at which point everything un-selects.
2) If I turn on checkboxes, I can click boxes and they stay selected when I lose focus BUT the checkboxes are cut off on the left side of the control. (The checkbox appears to go off the edge of the control.) There's plenty of space in the control for the checkbox and the listed items.
