View 2 RepliesI have this code for my shortcut keys
Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
If e.Shift = True And e.KeyCode = Keys.F3 Then
'Do something
End If
But I also have a button to send my program to the System tray like so:
NotifyIcon1.Visible = True
Me.Visible = False
How can I get my shortcut key to work while my program is in the system tray?
It doesn't work while its a notify icon
I wrote code for checking whether a particular process (Outlook.exe, in my case) is running or not. It is working fine when the Outlook window is open or minimized. But, when the Outlook is minimized to tray (which on the right side of taskbar), my code is not identifying the process.Could anyone please suggest me a way to get the process of Outlook (or any other program) that is minimized to tray?
View 2 RepliesMy cousin and I were discussing the difference between Java and VB.Net and I thought I would make a simple application to show him.
My form has two labels a numerical up and down component and a button.
I want to set it so when my cousin presses the button it will open and close his disk tray for the amount of time he chose using the numerical up and down.
I have tried making the program using a sample I have acquired but ti keeps throwing this error.
This is the error.

I have an app that minimizes to the system tray. If I try to run the app again (forgot it was already running in the tray) I have a routine that prevents that. What I want is for that same routine that is running in the second instance to Open the first instance of the app from the system tray.

my program has a tray icon and i want it to show up in the system tray. so i went into my windows notification area and set it to show icon for my app. But when my app update to a new version with clickonce, it will think its a new app and i have to set it again. Is there a way that it will treat all new version as the same program and i dont have to keep setting it?
View 3 RepliesI have an object Order with a simple event, Public Event ErrorOccurred(ByVal msg As String)that I raise in the constructor like so when an order cannot be found (along w/setting a boolean error flag:
RaiseEvent ErrorOccurred("This order does not exist in the database.")
[Error] = True
I have a webform subscribed to the order's ErrorOccurred event:
Public WithEvents o As New Order
and I have an error handler method on the form:
Private Sub OnErrorOccurred(ByVal msg As String) Handles o.ErrorOccurred
litMsg.Text = "<p class=""error-confirm"">" & msg & "</p>"

When a textbox is changed, it autoposts back to the page and employs the following logic:
Private Sub txtOrderID_TextChanged(ByVal sender As Object,_
ByVal e As System.EventArgs) Handles txtOrderID.TextChanged
If IsNumeric(txtOrderID.Text) Then
[code]....
When there is an error (when the Else logic is run), everything performs as expected except the event does not fire. However, since the Error flag is set to true, it means the event MUST have fired, since that line executes AFTER the RaiseEvent line. I've tried everything I can think of, but I cannot figure out what could be wrong. I have events strewn everywhere in my project and they all work well using virtually the same structure.
I'm using vb.net express with access 2010.Everything is working fine except for a simple query:SQL: SELECT * FROM Customers WHERE Name Like 'Ale*'Which returns all the names starting with Ale. Now in my .NET code I wrote this:cmd = New OleDbCommand("SELECT * FROM Customers WHERE Name Like " & Chr(39) & Name.Text & Chr(39), connection)Now when I start the app and in my textbox "name" I write Ale* I have the following expression:SQL: SELECT * FROM Customers WHERE Name Like 'Ale*'But when it executes from .NET (dr = cmd.ExecuteReader) it doesn't find ANYTHING.

Has this ever happened to anyone? It has happened to me and one of my customers in the past but I have no idea how he diagnosed it and it is happening with another one of my clients now. The application runs, but the HTTP requests do not. The application works 100% perfect on my own computer but not the customers. He has both the 1.1 and the 3.5 framework installed, and uses Vista (same as me). Can anyone shed some light on this situation because this is a huge huge huge problem that I would rather not have to worry about in the future with other clients.
View 6 RepliesI write a program designed for interacting with an Android phone that is hooked up to a Windows machine. One of the tools in my program is a utility designed to help the user root their phone.Now in order to root it goes through a command line utility called adb which lets you access a terminal on the phone. It must then type commands in that terminal. Most processes that this program does can be done through a batch file, however rooting the phone isn't one of them. The reason being once it actually logs in to the phone's shell, it stops running commands because it just gets stuck on that line, waiting for it to finish. So despite being a little primitive I designed that part of my application to use sendkeys. So the way it should work is:
1) It launches powershell as an adminstrator
2) Types the following commands (I have abbreviated the number of commands it types for the sake of this board. There's actually about 20 lines total): [code]
For the people that have this happen to them, it's always the exact same thing. It's like it completely skips all letters until it gets to a special character. I have no clue what could be causing this. The only thing I have found was that sendkeys wasn't totally supported but that running it as administrator would fix that, which is why I now have it run as admin. But that didn't help. I also had some success by using powershell instead of cmd, but it's still failing for a small number of people.Any ideas what would be causing this? Every other part of the program works perfect except for this. I haven't found any common element between the people that it is failing on. They aren't running the same anti-virus or the same programs. I program and debug on Windows 7 64 bit, yet someone else can run it on the same OS and it won't type it out properly.

I am working on an OpenGL Visual Basic 2010 Express project using Tao.dlls.My computer has crashed a few times while I was last working on my code.Since then There has been some side effects such as intelisense and autocomplete not working when I load the project, even after checking the options and settings for them.When I start a new project on the other hand the features work again.Also when this OpenGL code is run:
