on the form event: FormClosing I have this code that saves a treeview to xml, when it is saved it displays a message, but when I click the messagebox OK button, the messagebox keeps popping up and won't close that form.Here is the code I use:
Private Sub AddressBook_FormClosing(sender As System.Object, e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing 'Build our List of custom objects from our TreeView's Nodes
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 am trying to make my form when user clicks on the exit button it will go to the tasktray bar. But when right clicked it will exit the application. How would I do this? I have a ToolWindow
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", _
I have just done my program, just skeleton not completely, the final problem has not been solved up to this time.When I run my application, the Icon of its will be showed at TaskTray. I would like the icon is there when I exit fom of application and then If I double click on the Icon, the application will be showed.
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 am adding few LinkLabels dynamically during runtime. I have the IDs of all link labels added to the form. How can I show an error message when a particular linklabel is clicked?
For exmaple. Consider 5 Link labels as show below
Report 1 Report 2 Report 3 Report 4 Report 5
When LinkLable "Report 1" is clicked. I have to show a Message box which says "Report 1"
Note: I dont know how many link labels will be generated durig runtime.
I have a Main and a Secondary form. I want that the secondary form appear if the no button in the messagebox is pressed (but the main main don't). Only if I press the yes button or when closing the secondary form the Main must appear. How can I do that?
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 need to run sql database backup tasks everytime i click on Exit button.

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.
Private Sub CMDreturngame_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CMDreturngame.Click Dim gameID As Integer

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 have a DataGridView and when user clicks on a row, a messagebox pops up with some value. I would like to copy some portion of this text from the messagebox. Is there a way to do it?

I Have a Windows Form -Personnel form After you finish entering data there is a save command button become visible.this Save Btn works properly with this Function.[code]
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 have managed to create and code a file menu exit with the following code, however I just can't seem to find out how I am able to edit the red X in the top right hand side of the form next to the minimise and maximise buttons?
Private Sub ExitToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ExitToolStripMenuItem.Click Dim close As String close = MessageBox.Show("Are you sure you want to exit?", "Exit Log Book", MessageBoxButtons.YesNo, MessageBoxIcon.Question)
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
When a messagebox pops up, how can I bring a form infront of the messagebox (or switch betwen different forms) and then bring the messagebox back again again if I want to click OK button to proceed with the remaining code?
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 have recently implemented to following code on a good deal of my forms.
Public Overrides Function InitializeLifetimeService() As Object Return Nothing End Function
It has worked great to solve some of my odd application hangs when the application has been running > 1 week.However, when the user closes the program I now get an Application Crash screen.how to stop this? how to put it back to "normal" with a global variable?
Public Overrides Function InitializeLifetimeService() As Object if readytoExit then ' Return... not nothing?[code]......
