I have noticed when I close a form I have invoked using form.showdialog the form does not appear to be totally removed. If I load a value into a textbox and press my cancel button [Me.close() Return] and then reload the form the value in the textbox is still present. Also bindings are failing because they are already set up
View 10 RepliesI've created a program with a login form. Once you log in, the login form should close and the next form should display... my problem is...
If I use Me.Close()... than both forms close and the application terminates.
If I use Me.Hide()... than the application never unloads from memory and run indefinitely.
So what do I do? Neither of these work how I need them to.
Form1 is a mdi container. It has a bunch of forms that can load inside of it as mdi children. If I close each open form inside the form1, and then click the red X at the top right, application exits fine.If I click the red X without closing the forms inside I get: An unhandled exception of type 'System.CannotUnloadAppDomainException' occurred in mscorlib.dll
Additional information: Error while unloading appdomain. (Exception from HRESULT: 0x80131015) However I can break from it. How do I get the application to not show that error? What must I do to fix those inside forms or close when the red x is clicked?

The above code is what I used in VB6 to close all forms associated with my programs before my program closed. I have been searching for information on how to make sure all forms are closed when closing a VB2008 program.
I have seen info on using the Project Property Shutdown mode When startup form closes and I currently have this set.
Is this all that is really necessary? Will the garbage disposal close everything else to free up RAM?
Also, if I have several forms open and want to close all from the main form without closing each one individually, what is the best approach? Is there a collection like in VB6, go through the collection, compare it to the name of the main form and close it if it is not the main form?
It is my goal to write a program to run a retail store. I am an intermediate Access developer, so I have a good grasp of the basics.However, I find that developing in VB 2010 is quite different.I will have forms for:
Company Information
Employee Information
Supplier Information
Customer Information
Invoices & Purchase Orders
All I really need to know at this point is the code to open and close each form.
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 have two forms and a button on the first form. What i want is when i click the button the second form to show and the first one to close. But this isn't working with: Form2.show() Me.close All the application is closing with the code above.
View 4 RepliesHere is my problem: when I create a new form i want to close the old so it is not still running in the background. As in if the were to move on to a second form and the X-out the first form would still keep the program running. Normally i would do [me.close] and when that didnt work i tryed [me.form1.close] and then [dim frm1 = form1 frm1.close] with no luck. Could some one please tell me where i have gone wrong?
View 5 Repliesi 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:frmMainFrm1 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.then 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.

, When you hit esc a 2nd form comes up on top of the first. On the second form you are able to close the first or/and reload the first with different info. My problem is whenever i try and reload the 1st frm it doesn't close it just opens it again. So if i do it seven times i have seven windows of the first frm open... my codes is something likes this
Dim frm1 as new form1
frm1.close()
From what i was thinking it has to do with the "New" Part in the dim statement....

I want to do something like when click on the close button, a message box will pop up and if yes, close it else remain in the same form. But the following coding seems only consider one side while the other side is ignored.

Check = MsgBox("Do you want to quit?", Style, "Exit confirmation")
If Check = MsgBoxResult.Yes Then
Application.Exit()

Throughout our program, forms are opened like this[code]...
The problem is that when forms are closed, they seem to not really be closed, only hidden - if I add some text to a textbox and close/reopen the form, the text is still there, rather than the textbox being cleared like normal. This is presumably because the form always uses the same instance.
Is there any easy way to fix this other than going through the entire program and creating a new form instance for every ShowDialog() call (there are hundreds)?
I have an application that create forms and name it randomically. I would like at certain point, to be able to close one or more forms from the main window application.
View 4 RepliesI am currently working on a school database that I am having troubles with. I have the Table Adapters, Binding Source, and DataGridView all working, along with the Insert, Update and Delete Commands. I have the user open up the SubjectForm. On this form the user is looking at a DataGridView of the subjects table and everything that is in it. When the user clicks add new on the right side, it opens up a new form called AddNewSubject. When the user gets done adding the new subject in, a dialog box appears and says that the subject was added successfully. After the user clicks exit, it takes them right back to the SubjectForm where the DataGridView is. My question is, how do I update the data in that grid so that after the user clicks exit on the AddSubject Form, the new data will appear in the grid? I have tried a combination of things and they haven't worked. I will add my code at the bottom.[code]....

my application will remain open after closing every form. This is a recent issue in previous versions my application would close. I call dispose(true) on all form closing/closed events. (some forms require it on closing instead of close because of some custom made classes.)?
