VS 2008 Closing All Forms When Program Closes Vs. Closing All But Main Form
Jun 4, 2010Dim frm As Form
For Each frm In Forms
Set frm = Nothing
Next frm
The above code is what I used in VB6 to close all forms associated with my programs before my program closed. I have been searching for information on how to make sure all forms are closed when closing a VB2008 program.
I have seen info on using the Project Property Shutdown mode When startup form closes and I currently have this set.
Is this all that is really necessary? Will the garbage disposal close everything else to free up RAM?
Also, if I have several forms open and want to close all from the main form without closing each one individually, what is the best approach? Is there a collection like in VB6, go through the collection, compare it to the name of the main form and close it if it is not the main form?

Closing A Window While Opening Another / Opening A Url In The Same Tab
Jul 27, 2010I am making a program that edits my website with the input that I put in. But, it is requiring multiple forms (obviousily), but I don't know how to make it close the one I am in while opening the other. For example: I have a form that opens first that requires a Username and Password, so nobody can obviousily use it without knowing them. When I submit the correct username and password and go on with the editing, I need the login form to close. I do not know the coding for this part. Is it:

Closing Application Via X Button Without Closing Forms Inside Mdiparent Causes Exception Error
May 3, 2010Form1 is a mdi container. It has a bunch of forms that can load inside of it as mdi children. If I close each open form inside the form1, and then click the red X at the top right, application exits fine.If I click the red X without closing the forms inside I get: An unhandled exception of type 'System.CannotUnloadAppDomainException' occurred in mscorlib.dll
Additional information: Error while unloading appdomain. (Exception from HRESULT: 0x80131015) However I can break from it. How do I get the application to not show that error? What must I do to fix those inside forms or close when the red x is clicked?
Forms :: Opening Form Using A Threadpool?
Sep 15, 2009I want to open a VB.net form using a ThreadPool with a maximum of 10 threads. I need to do this because, the form should open based on a live event and i need atmost 10 forms on the desktop at a time. If i open the form on every live event without using a ThreadPool, the desktop will be floaded with many forms. I am using QueueUserWorkItem method of threadpool to queue a method which opens the form. In this queued method, there is form1.show() statement called. But after displaying the form, this method finishes execution and again we have 10 threads available in the system. I somehow want to either keep this method running so that 1 thread is occupied or i want to keep the thread alive till the form1 is closed by the user. I want the 11th form to appear on the desktop, only when any of the existing forms out of the 10 (already on desktop) is closed.

Stock/Inventory Calculations With Opening/closing Balance?
Sep 16, 2009I got stuck up with one issue of inventory/stock calculations and put my problem in four threads and grasped some ideas and thoughts for that. But could not find SQL query for this issue in those threads. i am able to construct SQL query for stock/inventory calculations. Since I could not find any SQL query as an example on this issue inspite of spending a lot of time and search, deifinitely there might be so many examples but i was unable to reach them, so after constructing this query i wanted to share my humble effort with all. It may be a second thought for beginners like me having the same problem.The second purpose of placing this query here is to welcome improvement or alternate of this query.

Using ONE Module With All Data Connection And Recordset Opening And Closing Options
Mar 19, 2012Finally starting some coding in VB.Net, I notice over the years, that we can say (in VB6)
Code: Dim MyForm_Stock as NEW frmStock
in the same session, being able to open, say 3 Stock Forms at the same time and maintain details independently of each of the other forms. Also am I able to maintain separate Database connections and the same table being opened and updated independently of each other by each separate form. What is actually taking place in terms of memory being used by each process? My ultimate goal is to be able to have ONE Module with all the possible data Connection and Recordset Opening and closing options, which I have failed miserably to do in my VB6 experience. Data access is an obvious module based set of subroutines. Others could be Date routines eg, Week Number of the year, Days Diff, Days to, etc. [Code]
