Forms :: Exit Application After Messagebox.ok Click
Mar 31, 2011
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 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'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 mini form application. What I need is to have a message box asking the user to confirm exist. Yes/No. This should happen if the user click the exit button on the form or the (X) on the title bar.
I have this piece of code attached to the exit button on the form. I'm trying to use an if statement but don't have a clue as to how I can apply it to what I already have.
Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click
MessageBox.Show("Are you sure you want to exit?", "Confirmation", _

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).

I am trying to do some extra credit stuff for school and was curious if there is a way to clear a text box after you would click ok in a MessageBox that pops up after an exception and/or an error. I have used a try/catch and would like the text the user entered text to disappear after they click OK in the message box that pops up. It would be great if i could get it to happen when either of the two message box OK buttons are clicked.[code]...

I 'm running a multithreaded VB.NET program. After running a particular task in the environment I'm displaying a MessageBox to indicate that the task is complete. Everything works fine, sending data, receiving data, displaying the data, etc. When I display the MessageBox and I click outside the MessageBox, the MessageBox goes behind my Main Screen.

I have an application that has a timer within the main form. Every 5 minutes it checks the database for notifications and if any are due it displays the details in a messagebox. If the main form is the active form, it works fine (message displayed). Even if I create another form and display that modally, the message is still displayed. If I minimize this second form, the message is displayed.
However, if I am writing an email when the timer is called, the message box isn't displayed on top.Is there any way to make sure the MessageBox.ShowDialog method always displays the dialog as topmost?I have tried using a new form instead of MessageBox.Show, setting the TopMost property to true, but that didn't work, either.

I want to show a MessageBox in a VB.NET application that has special markup for its text. More specifically, I want to display an unordered list. I tried doing it by wrapping the text in HTML tags (which Java Swing supports for example, if I'm not mistaken) and working with <ul> and <li>. This did how to do it without creating a completely custom messagebox class?

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.

The above is my code. I'm trying to get it to step into the bolded code when I click on no in the messagebox, but it keeps skipping. No idea why as I've wrote another piece of code with similar coding, which works perfectly fine.

I teach VB in college, using the Express edition. I was doing an exercise with my class today using the MessageBox.Show() method in a Windows Forms application. But when I tried entering it in the edit window, it gave me the following error message: 'show' is not a member of 'MessageBox' and it did not show up in the Intellisense box. Most of my students' computers did work with that method, but one or two of them didn't. Meanwhile, I had to revert to the MsgBox() function to get through the exercise.

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

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]
