Than From frmTWO , there a button to go back frmONE( i use the code frmOne.ShowDialog() )i click it throw a error saying :
"Additional information: Form that is already visible cannot be displayed as a modal dialog box. Set the form's visible property to false before calling showDialog. than i tried to set visible to false before .showdialog still got error saying :
"Additional information: Form showDialog tried to set an ineligible form as its owner. Forms cannot own themselves or their owners."y is this so , is there any other way to close a frm etc etc ?

I have a main form that has a button with which a smaller form is shown. Think of the smaller form as the Find/Replace dialog in many applications, such as Notepad. It's important that the form is (what I believe is called) modal. What I mean is that it always stays on top of the main form. I ensure that by calling the Show method with "Me" as the owner argument. Whenever the small form loses focus it will not disappear into the background but stay visible (albeit out of focus). If you don't understand open up Notepad and have a look at the behavior of the Find/Replace dialog.
Here's my problem: instead of actually closing the form when the X is pressed, I want it to simply Hide itself, so its position and the state of any controls (checkboxes etc) is preserved automatically.To achieve this I simply cancel the FormClosing event and Hide it:
vb.net
Private Sub Form2_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
[code]....
To show the form, I use the following (note the (Me) to make the main form the owner of the form; this ensures that it remains visible even when it is out of focus):
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Form2.Show(Me)
End Sub
Now. When I run my project, and open the Form2 (small form), then hide it again (by 'closing' it), I can no longer close the main form (Form1)! It seems the main form cannot close when the small form still exists (albeit invisible)...?? When I don't use the Me argument in the Show method, I don't get the behavior I want. I know I can set the TopMost property to True but that will also cause it to become visible on top of all the other forms, even windows not part of my application.

I have set up a notify icon for my form. I want to make it so that when the user clicks the close button that it doesn't close the form it just takes it to shows the notify icon. They can exit the program from the notify icon. Can someone tell me how to keep it running?

sometimes, when I use Form.close() when debugging my program, although the form is closed, the application is still running. I noticed this behaviour when using the msgbox function.

I have a situation where me.close() doesn't close the form. I have a form with a button with the code seen below. What happens when the button is clicked is the new form shows, but the original form(calling form) is still there. When I go into debug mode, I can see the me.close() execute, but nothing happens (calling form stays open). When I close the second form both forms close. If I comment out the call for the second form to open the first form closes without problem.
Private Sub cmdNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdNext.Click
Dim f As New frmOrder3

I am really new to Visual Studio and VB and I am having trouble closing a single form:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
End Sub
When I use Me.close() associated with this button it closes the entire project and not just the single form can anyone.

I'm writing an internal web application right now (with ASP.Net Web Forms), and it presents an odd problem. I have to be able to impersonate the currently logged in windows user, and execute a command based on their Windows Authentication to log in.. AND ... if they don't have Windows Authentication set up in the application I have to use to log them in, I have to be able to accept a user name and password. I also have to write the application in .Net 4.0, and secure it as much as possible. I got this to work by NOT utilizing Windows Authentication or Forms Authentication in the web.config, and instead setting session variables to guard against user accessing pages in the web app other that the log in. I did this by creating an oddly name session variable with a value based on their user name (windows auth or not), and then a secret session variable. The secret variable is in the web.config as a 256bit encrypted string, in which I decrypt, and set as the session secret. In order for the page to load, the first session variable can't be blank, and the second variable has to equal the decrypted key value... if the variables don't pass inspection, it redirects them to the login page. I set this up on every page, generic handler, and webservice method in the web app. I make the session timeout after a few minutes of no activity, and on log out, I set all session variables to nothing, and expire all cookies. (I also disable all cache).
My question is... Does this offer comparable security to that of Forms authentication? I have always used Forms authentication, but can't use it here. If I did, the users would have to reconfigure settings in IIS and in he web.config to toggle login procedures (From my knowledge, you can't use both Forms authentication, and windows authentication to manage the security of your pages and other web resources). With the method described above, I can accomplish the best of both worlds, but am curious about the security of my methods. Is there anything else I can implement here to assure the utmost security other that using forms authentication? Is it possible to accomplish the same level of security of Forms authentication without using it?

I'm currently working on an application that detects a color on a defined area on the screen and together with a panel that displays the color I show the values in a label and represent them with a vscrollbar. (The goal of the project is to output the color of the computer screen via an usb to dmx interface to create an ambilight effect) Now I don't want the user to be able to move the scrollbars up and down so I figured disabling them would do the trick but then the little square you click on to scroll it up and down isn't visible anymore.
Vscrolbars enabled:

I'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.

When I use
Me.Close()
Form1.Show()
It closes the whole app.
How would I change it so that it only closes the current form while opening a new one? EDIT: I put [Not Resolved] Because I accidently pressed the resolved thing

The form is an About Us form so has nothing on it only a text box and a OK button.
[Code]...
Why won't the button close the form? I'm puzzled, I tried another button just in case with the same result. UPDATE: I set a break point on Me.Close() and it isn't reaching it when I click the button, I created a new button and the same thing happened.

I have two forms , first one is search and second is showing the data searched by first form search criteria. When the search query runs it takes lot of sql server resources, so I have passed that query to second form, it searches in database and shows the results. But if the results are not found I wish to close the second form in Form load event. As Second forms form load event searches for the record. I tried to use SecondForm.close in SecondForm.load event but failed to do so.

I have been having a problem with closing only one of my forms for quite some time now. I will normally have a splash form that I want to close (and the main form to show) after the splash form is clicked. When I use frmSplash.close() ,in the frmMain_load procedure, it closes both forms; the same occurs if I try using me.close() in the frmSplash_click (even if it's after the frmMain.show).

I have two forms. The first one opens the second one after all fields are filled out successfully. The problem I am having is I want to close the first form when the second form is displayed, but every time I try using frmCustomer.Close() when the second page (Result) loads, it completely closes the entire application.What am I doing wrong? What is the correct way of doing this?
