Can't Put Deletion In Form Closing Because Program Is Still Running
Apr 14, 2009
I'm lending a copy of my .exe on a memory stick and because I dont completely trust them, , I would like to build in a function that as soon as my app has finished doing what its doing And the big red X is hit it will delete itself, but my problem is that i cant put the deletetion in the form closing because the prog is still running, so what should I do? Is there a way that I can get the app to close as soon as the dedicated task is complete, It will remove itself from the memory stick but if the X is hit before the process is complete the then the prog will remain.

Dim 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?

I have form1 and form2. A button on Form1 calls a thread background process (below). That process processes the command and when its done should close form2. I'm opening form2 within the current thread but trying to close it in the background thread. This is because if i close it in the current thread it closes immediately. I included the 2 functions below and what I have tried in the inline comments. Form2 is a simple form, basically just an animated gif. It is to show the user that something is happening(like a status bar) then close when its complete. I tried running different priorities instead of different threads but due to the results threading seems to behave the best. I'd like to keep access to both forms during the process, the pc, and screen refreshes realtime.[code]

I'm developing Applications in VB.NET 2008.
I have MDI Parent Form and i'm going load all form as MDI child. Here i'm going to give option to "Close All" toolstripbutton in top of MDI Parent to close All mdi child forms.
Now i would like to check that On click of Close All Toolstripbutton , i have to close all mdi child form but except those form is on process, example, I have opened/Loaded 5 MDI child forms within MDI Parent Form.
Child forms are ( just for example ) ,
1. Customer details Form
2. Item Details Form
3. Import Orders Form
4. Stock Details Form
5. Production Entry Form
Here 3.Import Orders form is importing from Excel with 5000 records and 4. Stock details form exporting to excel.
So now if i click "Close All" button then i have close only Idle form i.e 1,2 and 5 but i should not close 3 and 4 since its on some process.
So Is there any .NET option to check that form in process/idle or do I have to check manually by having any Flags ?

Does anybody know if it is possible to download email messages and send something to the email server to delete an email from the server using ASP.NET?
I have developed a program to download email information from my email server, but I can't figure out how to send something to the server to delete an email. I developed what I have using the resources at this location[url]...

On my program the user clicks a button which then runs the main code for my program. The problem is once the code is executed I can no longer move or interact with any form boxes, reliably at least . Sometimes there will be a period of delay where I can move it for an instance. Is there anyway I can make it so that my form is able to be moved while the program is running?

I am trying to write up a program that has a few forms that you interact with and do various things with but I also need to have a TCP/IP client/server running in the background to handle a automated connection to a PLC. Is there anyway to have the TCP connection open and receiving/sending in the background even when the operator is doing something else?

I have a parent form that has a list of items and each item has a unique ID. The user can open one or many of the items in a child form (it is set up in a tabbed MDI), but it can only open one instance of each item at a time.
In the parent form, I was going to make a collection (or something like that, maybe there is a better way) to keep track of which items are open in the child forms. I need to know when each child is closed so that it can be removed from the collection and reopened at a later time. I was thinking that when the child form closes, it somehow does something (like raise an event) that tells the parent form to remove the unique ID from the list of current open child forms.
My questions are, is this a good way to do this and I am pretty sure I would use the form closed event in the child form to update that parent form, but as well, I didn't know if this is the best way of handling it.
If raising the event is a good way, are some examples on how to do it out there? I found some for controls, but not while the form is closing/closed.

is there "rules" as to how to close programs writting in vb.net(2008)? I've migrated to dot net from vb6 and have rewritten some of my programs in the new language, but I've discovered a problem, since using the new programs if you try and close the machine down (Windows XP) the pc just hangs until I use the task manager and kill my programs.

I am working on a project that has the user building scrapbook pages through several different forms. When the user selects something a presses a button I have the information about the selection load to a list box which is on a CheckoutForm. One of the options I have is for the user to save what they have made (this includes the information in the list boxes) and return to a previous form to build another page. I have been trying to use the Me.Close() but it does not save the information and using Me.Hide() displays the wrong elements on the forms.

i have a parent form which is having a grid view. In the KeyDown event of the grid view i am calling a child form. If the user closed the child form, my application should close both the parent form and child form. What i have done is, i declared a boolean in the child form and passed the boolean value to parent. May be the code below will give the picture of what i am trying to do.

I have a unique challenge that I just cannot seem to get by...I have a form with a series of listboxes that allows the user to rename items in the listbox (I probably should be using a listview control instead). When the user right-clicks and selects rename from the context menu I show a simple form with two labels & text boxes showing the selected list box item in one textbox...the other is blank waiting for the user to enter a new name. What I'd like to do is when the user closes the rename form, the information is passed back to the calling form and a listbox refresh method is fired to show the changed name. Couple question:
First, is there an easier method to implement the renaming concept in a listbox (probably should be using a list view) i.e., have I overcomplicated things?

I have 2 forms. When a user clicks something on form1, form2 pops up. After user is done with form2 and closes it (where the dataset is updated), I want form1 to "reload" the dataset to reflect changes made in form2.
