Closing MainForm - Clicking On The "X" Does Not Execute The MnuQuit_Click Code
Jul 12, 2010
When the user clicks on the Quit menu item in my MainForm, some code is executed and then the program closes - this all works fine. But should the user click the "X" on the MainForm, I'd also like the MnuQuit_Click code to execute. The below code compiles with no errors, but clicking on the "X" does not execute the MnuQuit_Click code. I'm sure the answer is a simple one,

I have a windows application. I would like to run a statement while exiting my application. I tried adding my statement on FormClosing event. but it only executes if the application is closed properly. However, If the application is closed via task manager or system is restarted or logged out, etc. then the statement in closing or disposed event is not getting executed.
Private Sub Form1_Disposed(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Disposed
MsgBox("disposed") End Sub Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As FormClosingEventArgs) Handles Me.FormClosing
MsgBox("closing")
End Sub
can some one tell me how to get my statement executed even the user tries to log out or shut down or application is closed via task manger.

When the button is pressed, it all works and the following files are created: yahoo.dll and yahoo.pdb My question is this: What is the code to load the already compiled yahoo files to execute the code again, without having to recompile the code?

Been spending some time on Codility.com recently and it crossed my mind; how do they execute the code you have created (Specifically pertaining to C# and VB.NET) ?
What I am basically wondering is how would I take a textbox on a form type some code in it and then run that code? Is this possible without 3rd party tools?

Can anyone think of a clever way to execute a piece of code every time a form opens, application wide? I have an app with about 45 screens, and I don't want to drop code in each form load event.

how to run code "in the background".As a form is loaded into memory I have the following code filling a listbox from a database table with this sub.I read in one of the documents about making code efficient that I could make this execute in the background.The list box is not needed immediately.
Private Sub getReleaseChoices()

I have an app that allows a user to type in code that can be executed much like vba code in the office world.I currently execute this code with the Proprietary Dexterity code used with MS Dynamics - GP.However, my users need to be able to run outside the Dexterity world.The easy answer is to allow them to type in vb scripting or vb code instead of dex code.However, I can't find an easy way to dynamically execute their code within my methods.CodeCom looked like it could be the answer, but If i'm reading it right, I would have to know what libraries the user is using in their code for vb.Thus, I thought to simply limit them to vb scripting.Unfortunately, I can't find a way to execute vb scripting from within vb, (all the articles are ancient and most links fail - thus I gotta believe there is an easier way).I'm at a deadline where I developed the prototype but trying to use sql statements failed miserably when trying to execute.

I am totally new to VB2008, so please bear with this likely dumb question.
I have seen numerous "my first program" tutorial that show you how to create your form, put controls on it, etc. I can get through those just fine.
However, I am wondering: If I compile a set of subroutines into a .exe, how do I indicate which code/sub to execute initially? I am an old school programmer (remember COBOL?), and we always had a starting point; a set of code execute, that initiated execution of other subroutines, functions, etc.
I have dabbled in VBA for Excel, and MS Access, and even those, you indicate in the interface, and menus you create, that first bit of code that brings up the menu, or perhaps the program's main interface.

There may be times when it would be useful for your code to be able to find and close modal dialogs displayed by an application. Perhaps you do not want to have to wait indefinitely for your user's input, or are using the COM Web browser control to automatically navigate Web page and would like to interactively close alert messages that pop up.Digging into our Interop toolbox, we find that this is a relatively simple process using a few core Win32API calls. Starting with the handle of the main window associated with the dialog (this is the form from which the messagebox was shown, whether from your code or from a Web page hosted in a Web browser control on the form), the GetWindow function can be used to retrieve a handle to a dialog windows (called a popup by the Windows API) being displayed (if any). The same function can then be used to enumerate the child windows of the dialog to find a button on the dialog to click in order to close it, and the SendMessage API function can be used to simulate that click, effectlvely closing the dialog window.
NOTE: At the top of whatever code file you put this code, be sure to include the following line (thanks poiygon for pointing this out):Code:Imports System.Runtime.InteropServices this allows for the shortcuts to the DllImport attributes.[code]This sample can be easily modified to close a dialog in another application (by using the MainWindowHandle of that application in the LookForAndCloseIEPopup function, instead of "Me.Handle") or to close any other type of modal dialog message being displayed to your user.

I'm trying to accomplish something fairly simple in VB that I do everyday in JavaScript.I need to parse text between two strings (HTML tags mainly) that have multiple occurrences.
Sample Data:
<tag>test</tag>
<tag>test2</tag>
<tag>test3</tag>
If I wanted to grab the data in the 2nd <tag> in JavaScript I would simply do this:
var result = string.split('<tag>')[2].split('</tag>')[0];
And the only way I seem to get that to work in VB looks like this...
Dim from = string.IndexOf("<tag>")
Dim [to] = string.IndexOf("</tag>", from)
Dim result = string.Substring(from + "<tag>".Length, [to] - from - "<tag>".Length)

I have some code that access an API out on the web. One of the API's parameters allows me to let them know that I am testing.I would like to only set this parameter in my code when I am testing. Currently, I just comment the code out when I do a release build. Is there an automatic way of doing this based on the build configuration?

I have a VB.NET application with Enable application framework checked, and Splash screen set. At the same time, I need to run some code before the splash screen is loadedMyApplication_Startup seems to go later, so it's not suitable. I understand it's possible with custom splash screen, but would prefer any other way to make it without more complex customization.

I am calling a sub from a form load event. The procedure that is being called adds columns to a listview and then loops through an array to populate the listview. I have another procedure called after the loop that does not execute when the loop completes. Please advise as to what I am doing wrong for the code not to execute after the loop in the if/then/else statement or why it is not executing if I remove the if/then/else statement and just placed the called sub after the loop or why the code does not go back to the form load event and then call the next called sub.[code]
