I'm helping a friend port some code that I have written in Java to Visual Basic.NET. VB.NET is not my language of choose, so I am entirely new to it's quirks. How can I display keys from a HashTable in a ListBox?
View 2 RepliesHow do I bind a keyboard key to an event? Everything I have found so far is related to using the keyboard for shortcuts to buttons on the form. I guess you could say I want to do the opposite.
For example: This is just basic code I did while learning how to use the xBox controller with my windows forms.
If currentState.Buttons.LeftShoulder = ButtonState.Pressed Then
tbLB.Text = " Pressed"
Else
tbLB.Text = " Released"
End If
Instead of changing the text in my textbox I want to have the left shoulder button or maybe my Dpad act as the "Tab" (let me worry about the controller I've got that handled, as not not confuse anyone) key on the keyboard in order to navigate through my form by tabbing upward or downward through a menu. Then maybe use the "A" button on the controller as the "Enter" key.
Where in: Replacing "tbLB.Text = " Pressed"" with code that would press virtually press the "TAB" key.
Of course using the xBox controller is dealing with XNA, but at this point I have figured out some basics of using the controller with my forms, just need to know how to mimic the keyboard keys.

View 5 RepliesI am wondering if there is a way to get the keys from the registry and display them in a checked listbox. For example I want to get all the keys and there values from "HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun". This will allow me to see all the startup items. Is there a way that I can get all the values and display them in a checked listbox. I tried using the GetValue but it seems that you have to set the key that you want.

This is an experiment to learn something.
I have a class called logitem
it has a datetime property, and a message as string property
I have declared myLogEntries as List(of logItem)
I have a ListBox.
Ok now what?
I have searched but i am getting lost in all the examples.

View 1 Repliesim trying to make a program that only listens to a few keys that the user presses, and if one of them is pressed, it carries out a specified command.for example, right now,i found a keylogger that could carry out my command, but id rather use something else if possible. right now, i have a timer running this:
For i = 1 To 255
result = 0
result = GetAsyncKeyState(i)[code]....
Then, in the textbox1_textchanged, i search for like if textbox1.text.contains("M") or something.problem with this, is im pretty sure its a keylogger, and i dont want to have to have that. also, it does not work in vista.
Found a solution! (should have researched more throughly!)
