Forms :: Saving Data After Exit Application?
Aug 24, 2010
I'm a newbee with VBnet , I use vbnet2005 I have a major form called FORM1, and when I click the bottons in it it shows another form for example-I have these some forms (printscreen):
FORM1 - major form
FORM2 - calculation form ( there are few forms like this)
FORM3 - result form
What I need is:When I open FORM2 and get results I push the botton SEND and then it should send the values into FORM3 I don't know if the public variable will be good here because they are not constant , I can get different results in FORM2 ,and these results should be writen in textboxes only after I push send bottom.
I hope it is clear , I don't know how to do it,if you can give me a code for this or detailed answer , I would be very glad.

I have a basic three form application. It doesn't seem to close after navigating through forms. If I were to open the application, and the main form is displayed. If I press the X button, the application closes fine(Goes from processes) If I were to open the application, and then navigate from the main form to another form using me.hide & form1.show, and press the red X on Form1, the application again, closes fine.

I have a form which checks on load if an host (ip) is available. If not it shows a messagebox and exits the application.
Here is when the problem occurs.
Now the messagebox shows just a short time, then the app exits automatically. But what I would like is, after a user hits the OK button the app exits.
Here is the code I use:
Private Sub SplashScreen1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Try

I'm having a bit of a problem getting my application to close properly. Basically I have one main form from which all other forms open. If a user tries to close that main form, I want to bring up a MessageBox asking if they want to exit the application.However, when I try to do that it asks the question twice. It seems that the Application.Exit() is triggering the FormClosing event again for some reason, but I don't know of another way to exit the application. BTW, the main form isn't the startup form so I can't use the option to close when the startup form closes.

I want to store some information of the form in such a way that if the user quit/exit the application it stores the information. When user runs the application next time the information should be available to him. It also involve the restart of the computer. The application is in vb.net 3.5 framework. The one way that i can think of using flat files and encrypted data, but i can not do this. I do not to store any kind of data on client side and I can not store this information on server side. The problem is of getting client machine information and storing it on server.

My routine to check for updates is run as a separate process. Exiting the application is required to update, so a dialog asks the user, when an update is found, if they want to exit now. f they do, the code (from the update thread) calls Application.Exit().However, if the FormClosed event of any form that needs to be closed needs to access its controls, an invalid cross-thread operation is detected (which sounds pretty logical).

So I'm a beginner and I'm guessing this has been asked before, but can anyone tell me how to save multiple inputs from textboxes and radio buttons etc. as one whole umm... thing in a STANDALONE form. I don't want any extra CFG or INI files etc. Kind of like how a new profile in a game would work. I'm a beginner so please try to keep it simple (or if you already know of a thread with the exact same question please link that as a reply instead).

I do not have any code to show, but using asp.net, vb.net, and SQL with stored procedures.If on a page I have an item that is added to the database and therefore that information is "saved", is there a way to have an ("exit without saving") button on the page that does away with those changes?Using infragisitcs ultrawebgrid, you add an item to one table. You can add an item to another table on that page. i assume adding these items to the table automatically saves in the database. There is also a text box but without clicking save I do not believe that those items are actually added to the database. Update panel is used, I don't know if that matters.
If after someone adds to the table but then decides.. oh wait.. I don't want to do this just yet, is there a "one-click" way to act as if I never visited that page to add info? I'm assuming it would be deleting the entries but this would have to be limited to deleting ONLY those items added while making... we don't want people adding info, then going back and deleting once the "save" button has been pushed.

I have a small application that consist of five tables. The main table is called inventory. I have four tables linked to the Inventory table
[code...]
I can go in and enter data, create a new record and add more data and then click Save - nothing happens. I can cycle through the records and they will show. However when I exit and reenter the program (stop/start debugging) done of my new data is displayed.
I am thinking the problem has to be with the four tables connected to the main table via the ID's. Although a record is not being added to these subtables. So, I am not sure what's going on.
I have provided the code below. Please take a look and give me some direction.

I have been working on a project which is used by a company's sale team, to combine all the wanted input data in one place allowing the sales team to show customers, where switching to them could save them money.
Basically what i want is a program which can save single records, which can hold data added in other text boxes, or indeed take the data from the list view boxes which is the intended output. I want to be able to save that data, then be able to Open it up again at a later date, and even modify it.
enabled me to save the three ways to identify a single record, the index number, company name and the date it was added. However I now need a way to save the data entered in my other forms to these single records.

I am trying to make a routine to handle closing a program with a confirmation dialog box. The problem I am having is I cannot get the confirmation to work right. [Code] If I run this nothing happens. The dialog box goes away but the program stays open. I have also tried options with e.cancel and my version of visual studio (2008) does not recognize that as a proper command.

I am trying to close my application and I have coded on the form closing, form closed events to call an exit form which asks the user for confirmation to exit or not. All works fine. When I press the X button on the winform things act different. On the main form where I press the X btn I store some user ID data that I use throughout the app. If I press cancel on the exit form that data is lost from the main form and cannot be used afterwards. So if the user pressed by mistake the X btn and then presses cancel on the exit form the application loses some stored data and many functions stop working.

I have a validating event for a txtbox called txtname. If the user tries to leave txtname for another txt box without entering their name a messagebox comes up giving an error. I have an exit button which will when clicked ask you if you really want to leave then you can choose yes or no. I can't seem to figure out how to allow the user to click the exit button while leaving the txtname blank so it would bypass the error message and only bring up the exit prompt. Here's what I have coded for the validating event and the exit event.
Private Sub txtName_Validating(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles txtName.Validating
If IsNumeric(txtName.Text) Then

I am having trouble with some code I am writing to handle an Excel spreadsheet. The idea is that the dialog box is displayed which invites the user to select an Excel spreadsheet. Once they have done that, it is opened and a separate function checks to see whether Sheet1 exists returning Nothing if it is not found. The intention being the try/catch block picks it up and gracefully does nothing. The problem is that when the function returns nothing, the dialog box is still displayed and the sub doesn't seem to exit. [Code]

I'm creating an application in VB.Net (.NET 2.0) I've put on Exit button on the SplashScreen. When user wishes to click on that, the application must get exited. Actually when the splashscreen is displayed, a very lenghty method is executed behind the scene. But when user presses "X" on splashscreen, i want to exit whole application irrespective of its current execution state.
