I'm currently coding a program where I would like a dialogbox (with answers OK and Cancel) to essentially 'fake' a clicking of Cancel after 10 seconds.I've got the timer working, but I'm not sure how I'd go about actually cancelling the form in a different subroutine.

This is the code i have:

And when i cancel it just keeps poping up the closing dialog, and the same with no. but with yes it works fine.
The following code is a what I have done in order to show a MsgBox when an exit ITEM on a MenuStrip is clicked then it will give two different choices Yes and No. If Yes then it will close the application but if No then it should stay on the same page.
Private Sub ExitToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ExitMenu.Click
MsgBox("Are you sure you want to exit the program?", MsgBoxStyle.YesNo)
If MsgBoxResult.Yes = True Then
Application.Exit()
End If
I have developed an application where some data will be automatically be updated in an Excel File. I need to autmate the application in a way such that there will be no manual user intervention.However once data is updated in the Excel file I get a save dialog prompt asking the user to save the Excel file. I need to know if there is any way to automate this part i.e. automatically save the Excel file and exit the application once data is updated.

View 2 RepliesI am slightly confused on how a form should be closed. I have an exit button and have always done me.dispose in the click event. I just found out this causes the formclosing and formclosed not to be triggered. I found this out because I was updating the live database in the formclosing. Because of this I used me.close but this does not free up all the variables. Do I have to do me.close and then in the formclosed me.dispose in order to close a form correctly?

View 2 RepliesI have a project using Application Framework and then a main form which displays the main UI. There's another form I call it frmLog, which is solely used for logging any operations internal message logging. By default, I created a Global MyApplication logging object called myLogger which is an object of type frmLog. In Application_StartUp, I instantiate it by myLogger = New frmLog. On the main UI form, there's a button Show Log which does myLogger.Visible = Not myLogger.Visible.

What I wanted to do is close all opened workbooks. This code does the work IF there is at least one or more opened workbooks. My problem is IF there is NO opened workbook at all; It goes around unendlessly in the WHILE Loop. How do I not process the closing IF there is no any opened workbook at all? (NOTE: I found this code from somewhere else.)

I have created a splash screen and it fades in. When the splash screen closes, the main form (MDI) should open. The main form opens but then immediately closes.

ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
'Open the MDI form.

I tried to get around that by handling the Disposed event and calling Me.DestroyHandle(), and it worked, but not if the user resized the form so that it caused an IndexOutOfRangeException in BlurImage().The code is attached.

View 10 RepliesJust a small question here, I'm using a timer in my program which I set to change a variable called "time". I want to put a few if functions in i.e. if time = 5 then change label colour or something like that. Can I put these if functions into the form_load section of my code or will this cause problems? Is there somewhere you can put code without needing to click buttons or anything like that?

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?
The following code works fine, however if the user wants to cancel out from the openfiledialog they cant they are stuck in a loop. A loop I created in case they selected the wrong type of data file they could choose again. [Code]. I really need some help seeing where and how to let the user cancel out without the program continuing. I tried some dialog.dispose code but everywhere i seem to put it it generates an error somewhere.

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 can't seem to get one of my functions to work based on a timer. Every tick of the timer, I'm trying to call a function which will start periodically taking screen shots until the 'Finish' button is pressed. However, I've run into numerous errors and wondered if anyone could give me any insight or suggestions. Here is what I have so far.

One of the errors included "Public Sub RunAC() does not have the same signature as delegate". This might be really obvious, I'm a recent Computer Programmer / Analyst graduate with intermediate VB.net experience.
I have an application that i have developed which requires me to run a method in one of the classes on a timely basis. Basically, calling the method at an interval.I can do this if there's only a single object, but the number of objects that i have to create depends on the number of entries in a table. I was wondering if it's possible to add timer control dynamically and make the tick even call objects' methods at an interval.
View 8 RepliesI've been asked by management to convert all of my applications from VB 2005 to VB 2008 (in preparation for taking them to VB 2010). I have a VS 2005 application that uses an ADO Data adapter which was defined using the GUI. I normally define my connections in code, but have been asked to get away from that in favor of ADO (and similar) data adapters.When I run the conversion wizard in VS 2008, it appears to convert this program, with some warnings and I get the 'Conversion Completed' dialog box. However, the VS 2008, will not let me close the dialog box, even after waiting for 3 hours. The only way to get out is to reboot the system.
