VS 2008 Save Variable Vales After Close
Jun 3, 2011
This is the first time that I will have ever actually published a program and I have a question about when it goes into 'real use' Right now I have string variables that sets the values of a few text boxes that can be edited and 'saved' (the variable values change to the new input).
When I publish the program will these values be saved in the variables after the program is closed then re-opened? Or is everything reset when the program is restarted? And if it is all reset, is there anything internal (aka not a xml file or something) that will hold the data and keep the changes?

i had this working and i foudn the info on this forum, but i cant for the life of me renemebr how to do it, and searching for the thread all i can find is this:
[URL]
Which is not it, the method i used only involved a few clicks per item to set up and it made it so what ever selection was chosen in a combobox for example was saved, and then that selection was loaded on the apps next run, i know i had to do something in the application setting/databinding area of the properties.

How do I read all the text from a text file and save it as a string variable? For some reason I remembered it being something like this: IO.FromFile.ReadAllText("path") but thats not it.

I have a form with a listbox. I have controls on the form that can add items to the listbox with the click of a button. I already have the save file, open file dialogs working properly but I want to add something else that works with them. Lets say I open a file and the listbox adds all the strings from the file. Now, lets say I add something to the listbox and instead of saving the file, I just close the whole form. How do I make my program ask if i want to save the changes to the file when it is about to be closed? (I only want it to ask that IF there are changes to the file).

I have 2 Forms.Form 1 is main and holds a button that should show msgbox with date that is selected on datetimepicker which is on Form 2. Date shown on msgbox should be in short format (dd.MM.yyyy.).On program start datetimepicker should be reset to today and msgbox should show today date unless user selects another date on Form2. If user goes to From 2 and changes date Form 2 should save new value and msgbox should show it after button click on form1. How do i do this?I made myDate parameter in settings of type "DATE" and i didn't set a value.on form1 load i have:my.Settings.myDate = Today on Form2 load i have: datetimepicker1.Value = my.Settings.myDate on Form2 closing i have: my.Settings.myDate = datetimepicker1.Value
This sets date on picker correctly, but when i go to form2 and change value, then close form2 and reopen it it still shows date that i have chosen, but msgbox shows initial value.

How to declare a variable that never change from pageload until i close the page. Simple Case :
* ShowInfo.PageLoad() begins to execute for UserA.
* ShowInfo.Page_Load() begins to execute for UserB
* UserA has variable Dummy = 100.
[code]....
But the Result: Since UserB's was the last one assigned to (which remember... there is only one version of this in all of memory), the Dummy Variable is assigned for both users but different session. UserB sees Dummy = 20 but UserA sees Dummy = 20 too. I Want that the result is UserA Dummy = 100 & UserB Dummy = 20?

I have a form with textboxes for input. I have coded the Exit button to display a message box that asks the user if they want to save any data in the textboxes before exiting the program:
Private
Sub btnExit_Click(ByVal
sender As System.Object,
ByVal e
[code]....
The question I have if the textboxes are blank (nothing has been entered), how do I code the Exit button to close the program without displaying the message box asking the user to save the data.' Save the numbers. Call the btnSave_Click procedure.

My application is suppose to save the information that I put in the application that is in a listbox in form2. All the information is in form1, but I got it to save it in the listbox in form2 and I can see it when I load up the form2. Im suppose to make 10 different list for it, (it says it should be in arrays, but I dont know how to do it) and I should be able to save them everytime I put a new one in, but when I put a new list in the listbox and close the application and then reopen it, its erased, how do I save it and keep it in the lstbox so it doesnt get erased?

I have VB.net code (2005) that updates an Excel (2003) file but on close I get a pop up from Excel when my code is trying to close it. How can I close and save changes and not get the pop up? ("Save Changes Made").
I tried this:
vb
xlWorkBook.SaveAs(Filename:=excelFileName2, FileFormat:=Excel.XlFileFormat.xlExcel3)
But it renamed the "Sheet1" tab and I got more pop ups from Excel.

I'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.

I am really new to Visual Studio and VB and I am having trouble closing a single form:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
End Sub
When I use Me.close() associated with this button it closes the entire project and not just the single form can anyone.
