Is there a *simple* syntax that will close a form when a button is pressed and leave the application completely if there is only one form? In vb6 it is, e.g.
Private Sub Command2_Click()
Unload(me)
End Sub
I have got as far as knowing its Button2_Click...

Form1 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?
Is there any way I can find the exact reason a form is closing ? To be more specific , I'd like to find when a form is closing :1) because the user pressed the X button on the upper right corner2) due to code (Me.Close , MyForm.Close etc)I know I can use the FormClosing event and use this code :If e.CloseReason = CloseReason.UserClosing Thenhowever it seems that the CloseReason.UserClosing catches both cases (closed by te X button or by code) . So , is there any way I can find exactly the reason a form is closing ?Back in VB6 , the correspondent UnloadMode variable of the Form_Unload event could be "vbFormCode" which indicated specifically that the form was closed by code

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?
When I press "Show Desktop" button in the taskbar my main form "disappears". The only way to show it again is by pressing an other program which is open in the taskbar (lets say Word) to rise and unrise again.
View 1 RepliesI have a button on my form where I'm showing a ContextMenu when the user left clicks on it, I'm actually using MouseUp right now to show it.What I would like to have happen is the user click on the button, the button stays pressed while the ContextMenu shows, it returns to normal when the ContextMenu closes (Either a menu item was selected, the user hits the escape key or they click/tab to somewhere else). Also I'd like to position the ContextMenu in the lower left corner if the menu opens down or the top left corner if it opens up. So the left edge of the ContextMenu is flush with the left edge of the button.Moreso the button staying pressed until the ContextMenu is closed.
Edit: I'm also ok with this being it's own control inheriting the FW's Button that used the assigned ContextMenu as well.

I have a button on a form, and I want to increment a counter an display it in a lable, while the buttion is pressed. Similiar to a numberic up down control. The reason is that I want to use a custom looking button, rather than the look of the numeric up down control.
Is there an easy way to do that while the button is being pressed? Or would it make sense to change the look of the numberic up down (I don't want UP and DOWN on the same control, though).
When I press a button on my form i need it to open a file. E.g. I want it to open a song (in windows media player, windows media player is the default program to open mp3's)

When trying the above ^ it just says file cannot be found.
I'm developing a interface in VB.net which will control two stepper motors. Counting on your tips I managed to control them manually I mean, there're 4 buttons used to move the motors clockwise and anti-clockwise. The point is, the main part of our project is control the motors automatically. Our idea is based on two editable fields, X and Y, where the user would insert the displacement value he'd like the motor to move. After filling up both fields, the "GO" buttons would be pressed. So the loop would run depending on the displacement values in X and Y.
Attached you can find the main screen:

Im looking for guidance/example on how to track if a button was pressed so that I can turn on another button and turn off the first button. I am saving a bunch of user data to a text file & that works fine. Once the user enters all of the required data, I turn on button "btnCBSave". What I am trying to accomplish is once button "btnCBSave" has been pressed once, turn itself off and make button "btnCBNew" visable so that the user can enter new data.
My little chunk of code is below:
CODE:
On an form i have few labels, upon clicking on that labels i want to display an another form which contains 3 textboxes(Default,Current,New) and 3 buttons(Default,Current,new). I need to save the values of all the textboxes to the label's tag, but the label's text will contain the value of the textbox based upon the button which is pressed. i.e if 'Default' button is pressed then the 'Default' textbox text should be the label's text. I have created a class with three mem. variables to the save these class objects in the labels tag. But how should i know which button was pressed.
