I am creating a question and answer form and I have created a couple of error message boxes that will show up on different events. With the first set of code below it is supposed to show up when a user doesn't check any radio buttons and clicks the next button, however when the message appears even if they click ok it moves onto the next question without letting them chose an answer. For the second set of code it asks if a user wants to retry but even if they click X to cancel the message it still reverts back to the main page.
If rbAnswer1.Checked + rbAnswer2.Checked + rbAnswer3.Checked = False Then MsgBox("You must select an answer to continue.", _
MsgBoxStyle.Critical Or MsgBoxStyle.Question, _ "Error")
MsgBox("Are you sure you wish to retry? All current progress will be lost", _
MsgBoxStyle.Question Or MsgBoxStyle.Question, _
"PowerPoint Quiz")

I created a simple program which basically launches programs installed on 32-bit system in the C:Program Files directory. I purposely put an .exe line of code in the compiler but that .exe wasn't installed on the system, I was expecting for an error when I tried to click the launch button and I did. NOTE: I already have a beginning If statement and that program is actually installed in the system, works perfectly no errors appearing.
ElseIf lstMultimedia.SelectedItem = "HyperCam" Then Process.Start("C:Program FilesHyperCam 2HyCam2.exe") 'this program doesn't exist in the system"
When the error appeared I looked at it in detail and found it was a system.componentmodel.win32exception type of error, I'm guessing that means a file doesn't exist in the directory I specified therefore the program displays an error.Now what I want to do is display a message box saying along the lines "This program cannot be found in your system" or something like that. But I don't know what the actual syntax/code for it, so far from thinking I have this.
Else : lstMultimedia.SelectedItem = 'no idea what to put here Then MessageBox.Show("This application cannot be found in your system or is installed in a different directory", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error) End If

I am working on a program that incorporates a simple web browser within it. All is working fine so far except for the the Webbrowser1_Navigating and Webbrowser1_Navigated events.

I'm trying to make a game, pretty much a game like memory where you flip over a card and find the match. But because of how many buttons I need I was wondering if it was possible to show the picture in a message, all the pictures are funny motivational posters from photobucket so I want the player to be able to read the dialog. I've already tried doing
Dim picture as string = "1.jpg" Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click MessageBox.Show(picture) End Sub
but when I click the button nothing happens and yes the name of the picture in my bin folder is "1". I am using Microsoft Visual Basic 2008 Express Edition.
I have an object, say Order where if an error occurs, it raises the ErrorOccurred event. If I'm running some code in say, the codebehind for a .aspx page with an public Order registered as WithEvents and I want to check to see if an error has occurred before I run more code, how do I do this? I can't simply check theOrder.ErrorOccurred. Do I have to create a local boolean flag that switches over in the event handler (OnErrorOccurred)?
Example:
Public WithEvents theOrder As New Order Public Sub DoStuff() theOrder.DoSomething() If theOrder.ErrorOccurred Then

I've got a grid view. I want it to say "you have nothing to show" if there are no details.
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound If GridView1.Rows.Count = 0 Then
[Code].....
However; it seems to be working backwards and showing the message when there is data to display in the gird view and continues to be a blank page when there is not data to display in the grid view.
I've tried a variety of combinations with the below IF statement below but no success.
I have wrote a program that do a bit of calculations that takes about 10 min to complete, therefore I need to show a progress to user. I used a percentage in status bar to show the current status of program.
The problem is for updating the number after each iteration I use me.refresh to show the percentage. BUT whenever the program lose the focus for example working on other stuffs, the program cannot update the percentage anymore. And above the form shows not responding but do the job until get the result.

I am not sure if I need to write an if statement or just add the line MsgBox("Update Succesful") but with doing that there is no actual check to see if any change has been made.
Unless, my code is in a Try Cast to catch any exceptions, could I add the line like I said above, then in "Catch as Exception" add the lines MsgBox("Update Failed" - ex.message)
I have the code below which works fine, however, if a mandatory field is not populated it prompts a message box, what I want to do is display ONLY one message box and show all the messages at one go, instead of one at a time. Also, I want the cursor to be prompting to the next mandatory field to be inserted according to the list.

Im trying to do a lab that will obtain 10 numbers from the user using an InputBox() function, store them internally in a one-dimensional array, and then compute the average of the numbers and sort them in reverse numerical order. The program should control that 10 numbers (no more, no less) are entered, and that the numbers are fully validated as integers.
If the user enters non-numeric data, then an appropriate error message should be shown, and that number should be allowed to be re-entered as a valid number. Then all the numbers should be shown as a list in a 'message box'. So far I can get everything but the message box to show the list of numbers entered.
