I added a banning function to my program, to prevent certain people from using it (obviously). It checks for their IP and hostname, and if either match, display an error inside my error form. When that form closes, close the program. In the project properties, it's set to start shut down when the LAST form closes. This is the form closing code.
Private Sub DenyAccess_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
For i As Integer = My.Application.OpenForms.Count - 1 To 0 Step -1
I've got the following code that just does a WMI connect to a remote machine - I haven't setup any code to query anything yet but when I step through the code I don't get any errors. I get to the last debug.print statement and when I step over it the program exists. Almost like I've called a End. No errors or anything - it just exists. How come it doesn't take me back to the form? IF I comment out " scope.Connect()" then it ends the sub and returns to the form.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim displayString As String = "" Dim pcTag As String = "server"
how I can allow the program to exit while the textbox is empty but I can't figure out how it works really..it will not allow me to exit,enter, or tab out of the textbox while its empty.
Private Sub gradeTextBox_KeyPress(sender As Object, e As System.Windows.Forms.KeyPressEventArgs) Handles gradeTextBox.KeyPress Select Case e.KeyChar Case "0" To "9", vbBack, vbCr e.Handled = False
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Hide() Dim value As String = """" + Application.ExecutablePath + """ -nogui"

I want the program to exit the sub after the timer has been started. But if theres no args, it should just show itself. The problem is that it seems to not care about the exit sub thingy, cause it shows itself anyway.
I am trying to build a small program which will allow some one to click on the exit button and the sound will play and at the end of the sound the program will then close. The sound clip is about 3 seconds long Here is what I have:
Imports Microsoft.DirectX Imports Microsoft.DirectX.DirectSound Public Class Form1 Private Dsound As CSoundDevice
I have just started a simple project in VB 2008 express (having previous experience (not much though) in VB6). At the moment I have only 1 form and when I click on the red x close button the form closes but the process is still running in task manager. I have the following code which I assumed would exit the program and terminate the process but it doesnt seem to work[code]...
I have an application that the main screen currently has all exit functionality removed by use of a class. I want a certain key combination to exit the program, but cannot figure out how to do this. I.E. Ctrl + X.
I'm having a bit of a problem getting my application to close properly. Basically I have one main form from which all other forms open. If a user tries to close that main form, I want to bring up a MessageBox asking if they want to exit the application.However, when I try to do that it asks the question twice. It seems that the Application.Exit() is triggering the FormClosing event again for some reason, but I don't know of another way to exit the application. BTW, the main form isn't the startup form so I can't use the option to close when the startup form closes.
how to display folder on desktop:What I did was:My program read external text files and generate word documents files on d:stage-in.After program finished (exit VB application), how to display folder "d:stage_in" on screen.
I'm not asking how to exit the program( dispose() ) instead I have a program that checks if a certain process is running and if so it displays a message box, stops the process and (Should) exit the program. If the process is not detected then the program loads normally and opens an external program. My problem is that it stops the process and still runs the program. How can I fully stop the code and exit my program?
I have a mini form application. What I need is to have a message box asking the user to confirm exist. Yes/No. This should happen if the user click the exit button on the form or the (X) on the title bar.
I have this piece of code attached to the exit button on the form. I'm trying to use an if statement but don't have a clue as to how I can apply it to what I already have.
Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click MessageBox.Show("Are you sure you want to exit?", "Confirmation", _
Now I have a sub to validate a bunch of textboxes and combo boxes.I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement.But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions.
Basically, I am just trying to close the thread/process after it's done.
Private psi As ProcessStartInfo Private cmd As Process Public Delegate Sub InvokeWithString(ByVal text As String) Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim psi As New ProcessStartInfo("m7.bat") [Code] .....
I am trying to close the thread so once it's done, it closed for good and my form is closed as well. I tried Me.Close() which results in: "Cross-thread operation not valid: Control 'Form1' accessed from a thread other than the thread it was created on." Error.
Me.Invoke(New InvokeWithString(AddressOf CloseME), e) - Results in parameter mismatch error. However, things like Msgbox("Done") works perfectly.
Using VB 2010 Express.I have a TextBox on a form. I want to be able to enter some text, then press either the {Tab} or the {Enter} to leave. Tabbing out seems to be the default behavior, so no problem there, but how do I get the TextBox to respond to the {Enter} key?
In the project I am doing at the moment I want to disable the Exit ( X ) buttons in the top right corner of all my forms. So I found out this code which I�m using and is working fine:
Protected Overrides ReadOnly Property CreateParams() As CreateParams Get Dim cp As CreateParams = MyBase.CreateParams
I'm having issues with a progressbar. I've created a progressbar that reads registry variables and uses that input to update the progressbar and some status messages (so I can call it from vbscripts, etc). I want it so when my status bar hits 100%, the bar stops, waits a few seconds, and then quits. However, it seems the program processes the remaining code and quits the application before it has time to completely repaint the progress bar (I'm guessing this because it will usually update to about 10% before it exits).. I'm using something like this...
If prcnt = 100 Then progbar.Style = ProgressBarStyle.Blocks progbar.Value = 0
I want to make it so when cancel is used it exits the loop but I need the Input as a decimal. Do txtItems.Text = intCounter.ToString intCounter = intCounter + 1 msgInput = CDec(InputBox("Enter Item Price", "Item Price", "")) decSubTotal = msgInput + decSubTotal txtItemPrice.Text = msgInput.ToString("C2") [Code] .....
How do I exit from the recursive loop from the code below. I would like to notify the end-user to select a checkbox in a msgBox before I exit the loop.
I have just done my program, just skeleton not completely, the final problem has not been solved up to this time.When I run my application, the Icon of its will be showed at TaskTray. I would like the icon is there when I exit fom of application and then If I double click on the Icon, the application will be showed.
I've been programming a piece software in C++ for a few weeks now, and one of the things that I needed was a "Exit Message". I've started developing this software in VB because the C++ GUIs do not look as good as the VB GUIs. Here's the exit message code in C++:
//This function will handle all the messages for my window. LRESULT CALLBACK WindowProcedure (HWND hWnd, UINT uiMsg, WPARAM wParam, LPARAM lParam)
[Code]....
If I used that code and closed the window it would ask me if I wanted to quit the program. If I click yes it closes, if I click no it stays open.
I know how to create a yes/no message box in VB. But I do not know how to check if the user closed the program.
