Forms :: Code For The Exit Cross In The Top Right Corner?
Oct 9, 2010
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 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 an application with two forms - a splash form and the main form. The main form reads an XML file and displays data from the file in a rich text box. While that is happening the splash form is displayed. When the main form is ready to be displayed the splash form closes and the main form is displayed. I have a progress bar on the splash form to inform the user of the progress of the load. I want to set the maximum value for the progress bar to the number of elements in the XML file. In the main form I am using a reader to count the number of elements. After I get that number I wan to update the maximum on the progress bar control so it displays correctly. That is where I am getting the cross threading error. Now I could do that in the splash form. But where the real issue lies is I want to update the progress bar value every time I read an element in the main form process to read the XML file. That I don't think I can do in the splash form as it would duplicate the process of the main form and defeat the purpose of the splash form.
I have researched this issue but can't find an answer. I have tried the delegate route but I still get a cross-threading error. I assume that is because I am cross threading across forms.

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'm trying to do a basic function, I'm using Visual Basic 2008 express, I have a windows form with 1 textbox, 1 button and a serial port. When the button is pressed serialport1 is opened then the data received is trimmed to remove unwanted char from start and end and then is displayed in the textbox, when the button is pressed again the port is closed, this works fine but in debug mode I get a cross thread error, telling me I can't use textbox1.text=result

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

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 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 I close my VB.NET application it occasionally yields the following error code: The program '[1584] Foo.exe: Managed' has exited with code -1073741819 (0xc0000005). This error only occurs when one of the MDI child windows is maximized and then the program is subsequently closed. When I step through the code, the error appears to be generated after the execution of my "custom" code is complete. What might be the cause of such an error? Where might I find more information about this exit code (Google and Bing were little help - maybe I didn't search for the right thing)?

I'm setting up a simple app that has 2 variables, one from a combobox and one from a textbox.Putting all my code directly in the button1_click sub works just fine, however, I wanted to add a marquee progress bar so I tried to implement a backgroundworker.

and call it with Me.Invoke(New SetComboBoxTextDelegate(AddressOf SetComboBoxText), ComboBox1.Text)but it still throws the Cross-thread operation invalid error.

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 been getting sometimes with SOME libraries (be it included in the framework or not).[code]I'd expect the func.Call() to return an exception if something is up, or do anything to error out, but here it just murders my method which returns instantly! The same stuff here is also in a loop, which doesn't get any more iterations, it just stops executing this function and continues running the program.

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.

Now I have a sub to validate a bunch of textboxes and combo boxes.I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement.But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions.
