I've made an app with vb 2010, which holds a mainform. On it is a menutoolstrip with button, when I click on that button a second form is opened on a second monitor and the button is being checked (different color).
When I click the button again, it is unchecked, but the form on the second monitor is still open, while it should be closed.
Here is the code I use:

my web browser is my main form and it has a number of sub forms , how can i set it that when i close the main form my sub forms dont close ?
At the moment when i close the main form all the forms close
For speed, I've decided to use temporary tables as the recordsource for a report. The problem occurs when I try and tidy up after the report is closed by trying to drop the temp table. Trying to do this using database.execute "DROP TABLE x" where x is the name of the temp table. Get a Run-time 3211 error that the table still has locks. I figured that any locks generated by the report would be dropped at least by the Deactivate event, but that doesn't seem to be the case. how to use a temp table in the report withot incurring an enduring table lock? The report is the sole user.
View 1 RepliesI 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.

Currently, I have a LoginForm that authenticates a user and it works fine. I have a MainForm, which is displayed if a valid username and password is entered. I have done this by using the following code in my LoginForm:Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles
[Code]...
Now this does exactly what I want except I fear it's a work around and it's not the best approach. Also, note that I am using Me.Hide() to hide the LoginForm, is there a way to show the MainForm and then close the LoginForm instead of hiding it? Doesn't Me.Hide() call creates an overhead?
I'm creating an app, with a splashscreen, loginform (just enter a name) and a mainform.With I use my.settings. Now here comes the issue I run into.The splashscreen should check (onload) if the my.settings.user contains any info, if it does, the mainform should be shown, if not the loginform should be shown. On my app settings I have splashscreen set to the splashscreen and the first form is set to login form.

I created a new windows form application using VB 2010. I added no controls to the form. This is right "out of the box" app created by the VB windows form app wizard. I next added a FormClosed event handler. The handler gets called whenever I click the "x" on the form.Later I needed to close the form programatically in response to an event from an automation client. So I did something apparently farily dumb. I called "Me.Close()" Nothing happens. The form stays up on the screen. My FormClosed event handler is NOT called.The MSDN entry for "Close" doesn't give me a clue as to why this call doesn't work. Indeed, it seems to imply it should work.So I added a couple of lines of code after calling "Close()" since when I stepped across that line of code it appears that no other code would execute. Sure enough, as soon as I step over the call to Close(), I cannot step through any other lines of code.
Then I found another piece of form code while searching around and I found the code had what appeared to be an odd keyword just dangling in the code. The keyword, colored by the IDE as a VB keyword?So I typed "End" into my method and intellisense shows me "End Statement. Stops execution immediately". And it does. But is my FormClosed event handler called. No.I added "Inherits System.Windows.Forms.Form" to see if that had any effect. No change.So how does a form close itself programatically?
how can i do that? first form close and second open........i did that but first is only hiding not close

View 7 RepliesIs there any way to skip a the validating event of the active control when the close button of the form is clicked. It is very annoying when user wants to close the form, but due to the validate event of the active control, it asks for the valid input. The user is forced to give valid input to close the form. I have searched a lot for this on net but no any proper solution could be found.
View 5 RepliesI have a DGV.It has some columns.The columns are in the correct order e.g. 1,2,3,4 at design time.When I start debugging and then come back to VS, the order of the columns have changed and I have to put them back in the correct order everytime.After some testing I have realised it only occurs if
1) I make a change on the form that holds the DGV
2)Leave the form open in VS while I play the application ie. debug.
In a program I'm working on, I want a "Loading..." dialog to close when it can't log in to a site using the username and password provided by the user. Basically, I have the code set up right because the function it is supposed to carry out when that occurs does work, but for some reason it ends up in some really weird stuff happening. In the Loading form, I have it set to do "Form1.Show()" and then "Me.Close()", assuming it would simply show the login form and then close the Loading form. However, when this happens, the Loading form closes, and then for only an instant Form1 shows, and then the Loading form shows and Form1 closes. This happens forever until I stop the debugging, and I can't seem to figure out why. Am I using the wrong method? What exactly does Me.Close() do anyways? All I want to do is close the form and open another
View 5 RepliesWhen i close the startup form of my application, i want to see a msgbox. But in an event like FormClosed().So when i press the Exit button which contains the commands:
Me.Close() Me.Dispose() i can see the msgbox from the FormClosed() event. If i replace these two commands with End, i see nothing. And also if i end my app directly from the task manager i still see nothing. I tried many different events apart from FormClosed() (like Disposed, Leave etc) but i can't find a solution.
I am having trouble with the scope of some of my variables. I declare some structures in the load event of my Splash Screen.

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 want to make a form that is only closeable if you have the password. I want the user to be prompted with an alert box asking for a password whenever they try to exit the application. I also need to disable Alt+tab, Ctrl+Alt+Del from being used.
