I have some forms in my application and need to switch between them. I dont want to open another form over other form, in short I want the user to get a feel that he is working on one form only. Right now I am doing something like this but this is not what I want
[Code]....
In my project, I want the abiliity to switch between forms without closing them. What is the best way to do this? I have a "Login Splash Form" that you sign into, and then a Main Menu Form opens in Full Screen. I want this form always to stay open with the ability to open up other forms from this main menu screen as needed.
View 3 RepliesSo the program I have is an overlay for a bit of software that has a main Video out. Whenever I go between forms the video freezes for a tiny bit but is noticeable. I am using the following to go between forms,
vb
Form6.WindowState = FormWindowState.Maximized
Form6.Show()
Me.WindowState = FormWindowState.Minimized
Me.Hide()
Is there a better way to cause less work for the form, making there be no lag at all?
The problem I'm having is with the .close() event. Basically I've created the below code to prompt the user when closing the form they are currently viewing.
Private Sub Form_closed(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.FormClosing
If MessageBox.Show("Do you wish to exit?", "Program Name", MessageBoxButtons.YesNo) =

I am making a visual basic game. And in the game I have a few instances where I want to call open a window (let's save to save the user's preferences) from a form, then I want to go from that form to another one.
Example:
The user has completed the new game page. I have the users choices in a host of string, integer, and boolean variables. Now I want to use a generic saving screen I made with a progress bar. When I open up the saving box, I want to close or hide the new game setup menu (whichever I need to do). Then when it is done saving I want the Saving bar to return and cause the new game form to open the actual game form and close itself.
So I guess my question is this: What is a reliable(or correct) way to poll for a return in form to signal it to go ahead with execution?
Second:
This is similar to the first question. Instead of keeping the first form open when I use the saving form; is there a way I can save the name of a page I want the saving bar to go to once it's done?
I want the user to enter their prefered username before they start a new game for the first time. So I poll the saved username setting I have and if it equals "username" I want the Username entry form I made to pop up, but once it's done I want it to immediately call the new game screen. I also want to use this username entry form on the options screen so that the user can change their accepted name at anytime; but I want this screen to return back to the options screen.
What is the accept way to do this? Is it done through stacks? (form information -> stack : load new page : Do stuff: load stack value -> goto)
Finally:
Do I have to keep a window open (not close it) to access the variables that I have defined in it, and have stored values too? Does this apply to hiding too?

I have 2 listbox's, same locations/sizes (one behind the other). I have 2 buttons, and they just switch the views between the listbox's by changing their visibility propertyThe problem is listbox1, which gets populated first, displays just fine. No code in the program touches listbox2, except for 1 button that adds items. When switching to listbox2 to see the added items, the items are there (verified by debugging and hovering over the added variable), but the text that is displayed won't update. The text that is displayed is the text from listbox1.

The programme is called mydata and Colin is my User name. Anybody got any idea what is wrong and how to correct it. I have tried to run it in Visual Basic 2010 Express and get the same error.

I have an application I wrote that is in VB.NET 2.0. Works great, but I'd like to switch this application to Linq. I use ADO.NET to load XML into a datatable. The XML file has about 90,000 records in it. I then use the Datatable.Select to perform searches against that Datatable. The search control is a free form textbox. So if the user types in terms it searches instantly. Any further terms that are typed in continue to restrict the results. So you can type in Bob, or type in Bob Barker. Or type in Bob Barker Price is Right. The more criteria typed in the more narrowed your result. I bind the results to a gridview.
1) Go to Project Properties --> Advanced Compiler Settings and change the Target framework to 3.5 from 2.0.
2) Add the reference to System.XML.Linq, Add the Imports statement to the classes.
So I'm not sure what the best approach is going forward after that. I assume I use XDocument.Load, then my search subroutine runs against the XDocument. Do I just do the standard Linq query for this sort of repeated search? Like so:
Dim people =
from phonebook in doc.Root.Elements("phonebook")
where phonebook.Element("userid") = "whatever"
select phonebook

View 2 RepliesI am working on a website web site where each user has a culture setting to allow control of resources displayed. The main page has two views, one the log on screen, the second the main menu.
When first loaded the page displays with the culture settings of the previous user (if any). If I then log on as a user with a different culture setting the view changes to the main menu without changing the culture. Go to another page and the user's correct culture settings are picked up, go back to the main menu, uses the correct culture etc.
This is logical but is there a way (without redesigning the site to have a separate log in page and main menu) to reset the culture to the new user's when switching view?
