.net - 'Exit Sub' On DialogResult.OK Button?

Jan 4, 2011

I have a VB.NET form (CopyScenarioForm) with a OK button (DialogResult property = OK) and also assigned it as 'Accept Button" for the Form.

I show this form from my main Form (mainForm) using

If DialogResult.OK = CopyScenarioForm.ShowDialog() Then
DoSomething()
End if

Now when user clicks on the CopyScenarioForm.OK button, I want to validate his entries and if invalid I want to 'Exit Sub' from the OK button's click handler but when I do that the form still closes out and DoSomething() gets executed. Is there a way to stop this and keep the form alive and only exit if the inputs are valid. I noticed, if I change the OK button's DialogResult property to 'NONE' instead of 'OK' then it doesn't cause it to close. but then how Do I know how the user exited the form to execute DoSomething().

Bypass Validating Event For Exit Button?

Jan 31, 2009

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

Forms :: X Button With User Confirmation To Exit Or Not

Sep 3, 2009

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.

Asp.net - Exit Button Without Saving To Database When Items Have Already Been Added?

Oct 29, 2010

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.

FormClosing And Application.Exit Is Causing The MessageBox To Ask If Want To Exit Twice

Jun 12, 2007

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.

Several IF Statements With Exit Sub Or Nested IF Statement Without Exit Sub?

Dec 9, 2011

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.

But after the application closes there is still memory being held in Processes by the application. However, when pressing the [X] in the top of the form the application closes again but in this instance it is not held in Processes.
