How Do I Save Listbox Values When Form Is Closing? and how do I load saved listbox values when my form opens again? Listboxes just don't seem to want to save. I suggest trying it out before posting unless you know the answer because simply using property binding in the applications settings doesn't want to work.

i have a problem whith save of items that ar in combobox1 Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
[Code]...
Below is a project that I am creating and with it is a listview table with name and telephone number I can add and remove contacts no problem that part is solved
What I am trying to solve the problem to is how to save that data once the form is closed and be at the same point when I close the form'[code...]
Dim frm As Form
For Each frm In Forms
Set frm = Nothing
Next frm
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?
I have the following code to close a form which is a child. The problem is that when it closes, it closes the MDI parent too.

I have a form with a couple of multi-line text boxes, a couple of radio buttons, and a couple of check boxes. When the form is closed I need to save the values of the textboxes, radiobuttons and checkboxes so their values will be retained next time the form is open. I've done this in VB6 on form open and form close, but I cannot get the same module to work in .NET
Here was what I used in 6.0 to save:
Sub SaveFormState(ByVal SourceForm As Form)
Dim A As Long ' general purpose
Dim B As Long
Dim C As Long
Dim FileName As String ' where to save to

2. One of the combobox - room names (computer center, first meeting room, second meeting room, etc) on this multi same form, but it is limited from the admin, actually,the admin will assign the room to the manager to set the room. (I will do this room names combobox from the other table binding.) My question for this, is possible to have multi same form, but with different combobox values for each manager?
In my program, I require to have an essentially unlimited number of strings that I can keep their values after the program has closed.
View 6 RepliesIn my application I am using some sort of 'FirstRun Wizard' to make basic settings such as data path, theme settings and other adjustments before the application starts for the first time. I am using the following at Application Start to accomplish that:
If My.Settings.FirstStart = "1" Then
dlg_FirstRun.ShowDialog()
Me.Hide() 'Form1 - my main form
End If
Now, my "FirstRun" dialog has a Cancel Button and I want the application to exit entirely if that button is pressed. At first I used Application.Exit() but it looked a bit strange because my Form1 gets shown for a fraction of a second before the application closes. With Form1.Close() I can do the same thing and the advantage is that my form does not show up at all. However, I wonder if this is a save way of doing it?
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 a project using Application Framework and then a main form which displays the main UI. There's another form I call it frmLog, which is solely used for logging any operations internal message logging. By default, I created a Global MyApplication logging object called myLogger which is an object of type frmLog. In Application_StartUp, I instantiate it by myLogger = New frmLog. On the main UI form, there's a button Show Log which does myLogger.Visible = Not myLogger.Visible.

I have developed an application where some data will be automatically be updated in an Excel File. I need to autmate the application in a way such that there will be no manual user intervention.However once data is updated in the Excel file I get a save dialog prompt asking the user to save the Excel file. I need to know if there is any way to automate this part i.e. automatically save the Excel file and exit the application once data is updated.

lets say I have a form (form1) with lables a-z which are all designed with default text "0". So they all show 0 on program startup. which is fine. I also have a dialog with 2 TextBoxes; I want my program to update the default text/value on (only)form1 labels x, y and z to whatever was put into the textboxes when i press the OK button on the Dialog, so these specified labels show the 'new' value on next startup. Is it even possible or should I save the values to a file which loads the values in the specified labels on startup?
View 5 RepliesI have a listbox in my form that gets its values from a data table by data binding. My question is, when the data (row) is loaded it also selects the first line automatically. I do not want this because I want the listbox to select an item only when the user clicks on it. Otherwise, the iteme should ony be listed. Is there a way to manage this?

next form which we have to use stream reader to load one record at a time. The form has a next button to load the next record. How do I seperate each record (I am sorry for calling it a record if this is inappropriate) when use streamreader and how do I load a record at a time.
I know how to open a file and use streamreader, I just don't know how to read one record at a time and move to the next one.

View 3 RepliesAlright, I have a vb6 LEGACY application and new Functionality (Form) written in c#. I have a VB.NET COM Class as a wrapper. I can launch the .NET Form just fine. THe problem I am having is closing the .net form from vb6.
Example:
In VB6, I have something like this:
CODE:
But it does not work becuase frmViewer is Nothing for some reason. how I should close the .NET form that was launched from VB6?
I have a parent form that has a list of items and each item has a unique ID. The user can open one or many of the items in a child form (it is set up in a tabbed MDI), but it can only open one instance of each item at a time.
In the parent form, I was going to make a collection (or something like that, maybe there is a better way) to keep track of which items are open in the child forms. I need to know when each child is closed so that it can be removed from the collection and reopened at a later time. I was thinking that when the child form closes, it somehow does something (like raise an event) that tells the parent form to remove the unique ID from the list of current open child forms.
My questions are, is this a good way to do this and I am pretty sure I would use the form closed event in the child form to update that parent form, but as well, I didn't know if this is the best way of handling it.
If raising the event is a good way, are some examples on how to do it out there? I found some for controls, but not while the form is closing/closed.
for now, i am using this code but it doesnt give me what i want.. for example i want to list all the items with the string "1"
Dim x, count As Integer
x = ListBox1.Items.Count
count = 0

I am working on a project that has the user building scrapbook pages through several different forms. When the user selects something a presses a button I have the information about the selection load to a list box which is on a CheckoutForm. One of the options I have is for the user to save what they have made (this includes the information in the list boxes) and return to a previous form to build another page. I have been trying to use the Me.Close() but it does not save the information and using Me.Hide() displays the wrong elements on the forms.
View 5 Repliesi have a parent form which is having a grid view. In the KeyDown event of the grid view i am calling a child form. If the user closed the child form, my application should close both the parent form and child form. What i have done is, i declared a boolean in the child form and passed the boolean value to parent. May be the code below will give the picture of what i am trying to do.

I have a unique challenge that I just cannot seem to get by...I have a form with a series of listboxes that allows the user to rename items in the listbox (I probably should be using a listview control instead). When the user right-clicks and selects rename from the context menu I show a simple form with two labels & text boxes showing the selected list box item in one textbox...the other is blank waiting for the user to enter a new name. What I'd like to do is when the user closes the rename form, the information is passed back to the calling form and a listbox refresh method is fired to show the changed name. Couple question:
First, is there an easier method to implement the renaming concept in a listbox (probably should be using a list view) i.e., have I overcomplicated things?
I have 2 forms. When a user clicks something on form1, form2 pops up. After user is done with form2 and closes it (where the dataset is updated), I want form1 to "reload" the dataset to reflect changes made in form2.

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?
