Check In / Check Out Application
Jul 11, 2010
i am new to the whole visual basic deal altogether and i'm sure i jumped into the hardest version. anyway i am trying to make a program for my band director so that when he checks-in/out uniforms its faster and easier. i have the checkout done but the check in is a bit of a trick. i need to read the data in from the file and whenever ", " that character is read it need to go to the next text box so it starts with textbox1 which is lastname and goes to textbox6.

This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:

I am getting the check value correctly in the database using a Boolean.Here is one of the errors I am getting. Unable to cast object of type

I have an application that provides core services for a series of other applications.When another of these applications is started, I want to check that the service application is running and if not shutdown.What is the best method to check for the existence of the other app? I'm thinking that I should be using a global mutex in the services app and checking for it's existence in the other apps. Is this the correct way to proceed?

I was wondering if it is possible to check if a specific application is running when I open up a form.
If the application is running I want a label to say running, but if it isn't running then the label will say closed.

I've got an application which I want to only have 1 open.How would I make it check if the application is already open and only open if it isn't? I've had the idea of using 2 forms, one of which is the proper application and the other which just checks if its running then opens the other form.I would imagine it would check if there's more than 1 of the process name running and if there is close all others?

The application loads Patient info(PatientID, PatientName, Levels) from a .txt file on to the first form. The user then clicks the evaluate button and the patient information with cholesterol levels above 200 are displayed in three listboxes on the second form. The Second form exports that information to a .txt file and displays the total number today over 200 and the average

Using the Application Framework in a WinForms Project, I need to check conditions to determine whether the application should run at all and if it shouldn't run then I need to kill it before it even shows the main form. My conditional checking is occurring at the MyApplication.Startup event handler, so all I need is the method that shuts down or kills the current application.
I'm pretty sure this question's been asked a thousand times, a few of those even by me, but I can never remember the right language to get any useful info out of a Google or MSDN Search string.
It never hurts to try. In a worst case scenario, you'll learn from it.

while the application is running i'm using FileSystemWatcher to monitor the folder. But what if there are changes to the folder when the application is not running, how can I check for these changes when the application starts.(similar to how windows media player, for example, monitors your music folder. Even when you add songs to that folder when it is not running, it does discover them when it runs next time)

I have a simple console application which consists of a single executable and a DLL file. My project has a reference to the DLL. My question is how do I ensure the DLL is present in the same directory and prevent the console app from crashing? Although in reality the two files will probably never be separated, I want to make sure someone can diagnose the error without me there.
At first I tried adding File.Exists(PathToDLL) at the beginning of Sub Main(). If the file wasn't found, I was going to display a message and quit the application. But apparently if the DLL is referenced at any point in the code, a System.IO.FileNotFoundException is thrown regardless if the line is executed.
Is there some way to handle this in the executable itself without creating another executable to load that one?

I'm having a problem with some users, my vb tools always check at the splash screen a response from a server with a simple:
Dim MyResult as string = oWebclient.DownloadString("www.mydomain.com/page.php")
This actually works for most users but in some clients the firewalls I think they block this call or bypass or something like that, I found that after telling the user to turn off the firewall everything works ok, now I have some users that according to them they don't have a firewall or they already disable and still they have the problem.
You can see from the image the error message they receive, so my question is do you know any kind of free tool that I can send to the user to maybe log what program or whatever is blocking the program to connect?

The Enable Application Framework Check Box seems pretty well defined in a number oprevious postings, but leaves one question in my mind. The default is unchecked and the sub-topic Check boxes are:
Enable XP Visual Styles - - Checked
Make Single Instance Appllication - - Not Checked
Save My.Settings On Shutdown - -Checked
There are also 3 Combo Boxes:
Authentication Mode - - "Windows"
Shutdown Mode - - "When startup form closes"
Splash Screen - - (None)
When I un check the Enable Application Framework Check Box all items under it are grayed out. However, if I have changed one of the Comb Boxes my selection is also grayed out...My question is, have I lost the use of those function: Specifically I am mos interested in starting my application from a Sub Main and closing the application when all forms close.My underlying question is . . . are the greyed out selections still valid?

I need my application to check for internet connectivity on my user's computer. If there is, an image is displayed and if there isn't, a different image is displayed. Here's the code I used to get this to work:
Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
If NetworkInformation.NetworkInterface.GetIsNetworkAvailable Then
Dim bi1 As New BitmapImage
[code]....
I decided to test this on my own computer by changing my default gateway (thereby making it seem as if I lost connection). But I realized that the code still showed that I was connected. So I'm thinking that it's only checking for connectivity of the interface - which in this case, is my connection to the router (which is true, I was connected to the router).How do I check that the user's PC is actually connected to the internet? I read the article Check for Internet connectivity but it's in C# and I don't understand that.
