View 1 RepliesI 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.

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 7 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 was referred to this forum section for VB2008 questions instead of VB6, so Ill assume this is the right place to ask this question. Yes I copy/pasted.I'm EXTREMELY new to VB2008 and I was basically making a program that is used for "password storage" that will be used only by me, I have made a simple login page that will not allow new usernames/passwords and a simple text box-listbox-add-delete page for submitting and displaying what I wish. What Im trying to do is make it so every time I open the listbox form, you are prompted with the login form. Im not sure of a proper term for this as I just downloaded VB2008 2 days ago.

View 1 RepliesI have an issue with my .NET application and it can only be reproduced sometimes and only on client's location, which makes it extremely difficult to resolve. In the application the forms authentication is used. There is a login page to which every anonymous user is redirected. After user enters username and password, it redirects to DefaultURL or some predefined page. The problem is that sometimes when user enters correct username and password, it doesn't login, instead it just refreshes the login page without any error messages. After several tries of inputing username and password, user is able to login to the system.
See my login page Submit_Click code below:
Dim userName As String = tbUsername.Text
Dim password As String = tbPassword.Text
Dim returnUrl As String = Request("returnUrl")

View 1 RepliesI'm working on a simple calculator program for work in VB.NET and I'd like it that an operation could be performed without a mouse click and instead by using the Enter key. So essentially I want the segment of the program that is usually run by button to have the ability to be run by the Enter key.I'm using VS2010.This is what I was trying to do but I suppose I'm not doing it correctly because the Enter key does not do anything when I press it.

View 1 RepliesI hava a form app, that runs hidden, with just a notify icon, the goal is control worker schedule and alert them for some things they have to do.My problem is,when i open a form (with TopMost = True), it works if the user is admin of the machine or domain admin, if the user is "regular" user, the form just don't open or shown to the screen.I believe that it has got something to do with write permissions in the app folder. I have a contextmenu that works great, even restoring the hidden main form, it just doesn't show/open the other form, without any error.Shouldn't .net use the user $temp folder to write something? If not what's the best way for the app use the EnvironmentVariable("temp")?

View 1 RepliesI have this weird issue:I developed an application with a sequence like this login form -> mainform (=mdi parent) --> some functionform (mdi-child)--> report form
The reportform contains a reportviewer and will display different dataset queries depending on the state of some radio buttons which are located on the previous form ('some function form'). When I run the project directly from the 'some function form' (set startup form for project) things work great. The report shows the correct data depending on choices made on the previous form.But....when I run the project all the way from login and mainform it doesn't work. Seems like the choices made on the "some function form' are not coming through to the report form.

View 7 RepliesI was sent here by someone else that said someone here might.Below. is the message I get every time I reboot. I am not sure if it's a .NetFrame Work 1.0 or 1.1 error or not. It may be Visual Basic as I really don't know. Also, may be where I uninstalled some program or another the wrong way, by just deleting the folder instead of using the add and remove programs. I did have 1 program uninstall in-correctly by Revo Pro Uninstaller also about the time I started getting this error. But, I do know in the header error box it does say ".NetFrame Work" though... I just adding these suggestion as it might help you know what the problem might be. I have XP Home 2002 with Service Pack 3 installed. I have repaired the .Net FrameWork 2.0, 3.0 , 3.5 and 4.0. I couldn't repair the 1.0 or the 1.1 as I have deleted my temp folders that must have had something the installer needed in them. I tried to repair them with the "Installer" located in the "Installer" folder but it ask for some file in the temp directory that I did not have so I had to cancel the repair.

I did a function to one of my projects to a DLL file, and when the user starts the function a icon for that function grows (to show that the function is open).When the user closes the function the icon should shrink back again. But i have some problem whit that.The problem is: when i open a other form, the icon shrinks even if i haven't closed the function.What make it strange is that i have 2 function like that, the first one is the one that is behaving like this and the second one works the same way, but the second icon do not shrink when i open a new form. The second icon only shrinks when i close that function.
Here is the code for the opening of the first function:
Private Sub MedlemskortToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MedlemskortToolStripMenuItem.Click
frmm = New Medlemdskort.Form1
frmm.datap = Application.StartupPath & "\database2.mdb"

View 13 RepliesI have a form created in VB.net. It is used to get some information form a user. The form is not bound to any data source.
A combobox on this form is used to enter a cost. I want the value entered by the user to be displayed using currency format. I have used the Format String Dialog that opens from the ellipses button on the FormatString property of the combobox and selected Currency. This put C2 into the FormatString property.
When I run my application, this format is not applied to the value entered into the combobox at the time the number is entered or when I leave the combobox.
I set the HourGlass, disable the button (to avoid ppl that are too used with FPS games), do the serial communication bit that last a couple of seconds, then the set the mouse back to normal and re-enable the button.And I have a few more like those through the software using text boxes or drop-down menus.[code]My form is set in design time to be KeyPreview = True and I even tried to set it again after the Click. The routine is simply not called and the ESC key on the keyboard does not hide the form anymore.

I have a test app driven by bluetooth serial events In my form load code I hide the cursor so it doesn't get in the way of pictures (fullscreen) When one event is called by bluetooth, it brings up a msgbox and the user has to click OK. I tried Windows.Forms.Cursor.Show() but it doesn't work.
I'm guessing it's something to do with delegates and events and the form, but the debugger doesn't complain at any point. It just refuses to show the cursor. How can I get my serialport event to show the cursor? And then hide it after?
