I have a simple for loop with the following code
For i As Integer = 0 To 4
Snake(i).X = (120 - 20 * i)
Snake(i).Y = 120
SnakeBody(i).Location = New Point(Snake(i).X, Snake(i).Y)
Snake(i).Facing = 3
Next i
But for some reason I unable to debug it. I place a breakpoint on the line Snake(i).X = (120 - 20 * i) and When I try to see what the values are the second time the loop iterates it simply exits the loop.

I place a break point on the enumerator = searcher.Get.GetEnumerator() line, and it exits and runs the app after moving past the While enumerator.MoveNext line (into the While loop). No code runs after this point.
I've previously posted with regards to searching for a string within Excel, although the replies were enough to get my application 'working' the solution was riddled with over-complicated methods.Therefore I bought some books and figured it out for myself and came up with the below (which works like a charm may I add).
Dim oExcel As New Microsoft.Office.Interop.Excel.Application
Dim oBook As Microsoft.Office.Interop.Excel.Workbook
Dim oSheet As Microsoft.Office.Interop.Excel.Worksheet

None of these (even if combined) make ANY effect whatsoever.I have also saved the workbook on exit, again to no avail.
Trying to exit an application but can't seem to kill it without an error."An error occurred creating the form. See Exception.InnerException for details. The error is: The form referred to itself during construction from a default instance, which led to infinite recursion. Within the Form's constructor refer to the form using 'Me.'"The form hasn't loaded yet, it is still in the process of looking for a file to load, if the user doesn't want to specify a working directory, that is their choice, but I need to close the app since it can't continue without it.I'm stuck in a class and can't get back to the main form without it continuing to load everything up. I wan't to force a shut down. [code] I was trying to get back to the main form without loading any more from the class to kill it there. [code]

View 1 RepliesI find myself frequently turning off Intellisense because it adds wrong choices to my code. For example if I try to type "i " (without the quotes) it causes "int " to be put into my code. If I type "for " it may put "form " into my text.
Reaching for the ESC key constantly slows down my typing. (It's such a long way to reach for small hands). Is there an alternative way to exit out of intellisense without the highlighted choice being placed into my code, or is a way I can define a different key for this purpose?
I want to make a button that opens a program. Just for the sake of this post, we'll call the program Notepad.I want the users of my program to open Notepad, but not everyone saves Notepad in the same location. Is it possible to save a value (and the text in the TextBox) so the user doesn't have to retype it every time the program loads?
View 4 Repliesthe application I am developing does not exit completely. i.e. the process can be seen in the Task manager. This happens only when I click on the [X] button on the title bar of the window of my MDI form. If I use the File >> Exit in the menu of my application, it exits without leaving any traces. I have used the "End" method there. But the process stays when I click the [X] on the control box on the title bar.

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

We have an application that works well on XP/Pro, Vista, Windows 7, Windows 2003 Server, Windows 2008 Server (32 bit) but is problematic on Windows 2008 Server (64 bit). The application uses an unsigned activeX control which may or may not be related to the problem. To install we need to add the program name and regsvr32 as DEP exceptions. Once that is done the application installs correctly and operates normally except when the application closes.
If a user clicks the 'exit' button our code basically says 'unload me' (where me = the main form of the application) and there is no code in the form_unload section of the program.
Everything works well on every Windows platform except Win 2008 64 bit where we get

Im using VB.NET 2008
I know I can exit a program by using the End statement.
But i was wanting to know how to check to see if the data has been changed since it was loaded and bring up a diaglog box up saying the data has been changed or not saved, would you like to save the data before exiting?
I will have a form that will have a yes, no, and cancel buttons.

I have written a windows application, that can take in some command line arguments and can be ran from the command line as a scheduled task. It all works fine, but i am trying to give the user some feedback on the console if they launch it from thee.I have used the info described here, and have got some output on the command line, but when the application finishes it does not drop back to the command prompt unless you hit enter it just sits there waiting.
View 2 RepliesI've been applying some recursive techniques to the second version of my app. This recursive procedure simply iterates through all nodes in a tree view and tests whether the text in the "department text box" matches the text name of a particular node. If there is a match, then the user's name, stored in the "name" variable, is added as a node to the node that has the same name as the department text box text.

I have a Visual Basic application that I use to access an SQL 2008 database. When I add a record to my table everything appears to be fine. As long as I keep visual studio running the data remains in the database. But if I exit visual studio and then reopen visual studio the data in the table is gone. I can reenter the data and again everything look fine. When I created this application I selected my SQL Server database from the Add New Item dialog. I selected service-based database. Instead of creating the database from the server explorer. Are there settings I need to change when a database is created this way?

I have a spreadsheet that contains details of change requests; one row per request. This information needs to be copied into a Word form for sending off to our customer who then completes the response section. To speed up this process I have written some code that utilises the mail merge feature of Word and merges the relevant info from the spreadsheet into a Word form. This runs from Excel when a button is pressed.The problem comes when I go to save the workbook and exit Excel; it stays running in the background as a process in task manager.

I'm fairly sure it has something to do with the merge code itself but my knowledge of VB is enough to grasp what is happening but not why it is happening. If I open the Word doc that has the merge fields in it, then open the spreadsheet that houses the info Excel says the workbook is already open.
