Form Closed When Use RightToLeftLayout?
May 24, 2008
I am making the interface controls on my forms to go from right to left using with RightToLeftLayout and RightToLeft which I have set the properties set to true. When I run the application and I open another form on the same application that I am using, I click the button to set the form to go from right to left. When I click the button where the code are running, it close one form as it leave the one other form running. There is no code like Me.Close() that required to close one form. I am using Me.RightToLeftLayout = True,

for example i have this code :
Sub Month()
Dim Conn As New Data.OracleClient.OracleConnection
Conn.Open()
Try
Dim Cmd As New Data.OracleClient.OracleCommand
With Cmd
[Code]...
What will happen to the datareader when the Connection is closed ( Conn.close)
Will the Cursor that is used by the datareader be freed ? or will it stay open ?
If the cursor that is used by the datareader is still open , when will it be automatically closed ? or should i just closed it manually ?
Will it cause the dreaded "ORA-01000: maximum open cursors exceeded" ?

I am trying to delete a file after viewing it. I loosely copied the code from [URL]. The problem I am running into is the filename I am passing is still in use after I close this form. How to get id where the file is being held open. Here is the relevant portion of the code. This is how I am opening it

PicImage.ImageLocation = PassedImage
PicImage.SizeMode = PictureBoxSizeMode.Zoom
cboFrameNo.Items.Clear()
'Sets the tiff file as an image object.

I need a way to detect when a child form has been closed. I've created an MdiWindowList thing (but in the form of a toolbar with buttons, similarly to the Windows taskbar), and everything works great, but the method I have for refreshing the taskbar's windows has to be called when a child form closes. I've trying calling the method from the child's Form_Closing event, but there's a slight lag so whenever there's more than 1 window open the first one gets skipped (then the others close properly, since the taskbar is being refreshed first before the form actually closes).

Works fine the first time but after closing the form opened by the DC, if I try to open it again, throws an exception "Cannot access a disposed object".
Since I can still access any other form not previously showed I guess that the closing changes a status that allowed the form to be .Show, there is no F.Load , F.Activate after the exception doesn't seem to do anything. What should I do?

I need to know if a form2 is already open when a button1 on form1 is clicked. I found the following code which fails when I open form2 then close form2. When I click button1 on form1 nothing happens. Is there a way to reset form2 to nothing or is this just wrong?
Sub isFormOpen()
If xmlTest Is Nothing Then
xmlTest.Show()
OpenXML(filename)

When a sub runs, it is using up large chunks of memory on every pass. It is loading pics into a listview. The pics are 1 to 2mb each and it is consuming 30-60mb for each one. How to release the memory once I close the form. Is there anything I can do to reduce it?

I have a checkbox on Form2 that will enable an email notification. From Form1, it tests the .Checked property of the Form2 checkbox. What is happening is that the checkbox reverts to unchecked (default at run time) each time the form is closed.
What is the best way to keep the checkbox checked once the form is closed so that it will enable the email notification?

Currently i am using the closing event, but i dont get it to work properly.

I have a webbrowser I'm making, and my listbox items for form2 disappear once I close form2 and reopen form 2. However, once I restart the program (Close everything) and re-enter, the data is saved. But once I reopen the selected form, the listbox items are lost. Here is my code (It's long)

I have a form that contains a crystal report viewer. When I open this form, it runs a report. I am using a .LDB viewer to tell who is logged into an access database. I noticed that when this form opens, the computer logs into the database and stays logged in. Even when the form is closed, the computer is listed as "logged in". If I run the report again, it just adds another instance of that same computer logged in. Therefore, it continues to pile up logins until the application is closed.

I created another form that had a pic and two simple buttons, one button plays music the other will stop the music if played and take you back to the previous form. My problem lies in when the users uses the windows "x" button to flose the form, the music does not stop. I have searched and failed and light that could be shed would be awesome.Apparently I saved the wrong file and am not on my VB box so this code is incorrect. I basically added the music to the resources, dim'd it and activated it with a button. The other button not listed in this code was set to "portal.stop()" and "Me.Close()"

Using vb.net. I've got a main form that displays when application is opened. A popup form can then be opened. If there are other windows opened on the desktop, for example windows explorer, then when the popup form is closed, the main form gets hidden behind windows explorer. You have to move windows explorer out of the way to get to the main form. Is there a way to keep this from happening?

I got a strange form in my project that doesn't close when I close it, so every time the user will use it, it will stay on system processes. The form is not even shown on the taskbar when it is loaded. It is just a regular form - System.Windows.Forms.Form.

I have a question regarding waiting for closing a window or changing focus back to my app. What i have is an app that creates a few tables, that then puts the tables into a temp file that wordpad opens for the user to check they are correct, this is where i need help, i would like to now wordpad is open wait until the user closes wordpad or changes the focus away from wordpad until i open the next form which is responsible for using the tables and converting them into xml.
Which event should i look at using that fires when a program is exited or gets focus?

Im using a dataset to display data in a datagrid from a sql server DB. One of the colums I have in my datagrid is "Status" the table adapter sql statment selects certain items based on whether there open or closed e.g "where = Open ". I want to remove this row entirely and instead of displaying open or closed for status column, display the open/ closed results in colour on the datagrid. Im really not sure how to go about this whether i need to do it in the table adapter or some sort of property. I presume i need to write a sql statement and selct the identity of the row where x= open etc , is there a way of assigning a colour in sql statement so it displays on my vb form ?

I have a form in a Windows form application that I want to display on top of a main form, close it, and then immediately show a dialog box using MessageBox.Show(). But the first form is still showing when the message box is shown, and it does not disappear until I click OK on the message box. I tried waiting to show the message box in an event handler for the form's VisibleChanged event and even calling Refresh() on both the form and the main form. Is there a way I can determine when the first form has fully disappeared before displaying the message box?
Edit:Here is some code that demonstrates how the forms are being shown.
static class Program
{
// The main form is shown like this:
static void Main()

I have been looking all over the internet and i don't understand what people are saying.
If anyone can tell me a way of knowing when my laptops lid is closed in vb.net that would be fantastic.
