As Windows 2000 and Windows XP obtain exclusive access to Input and Output reports for keyboard/mouse devices.
Ok so I've been searching the forums for the past hour (I used the search feature) and have had no luck coming across what I wanted to do.
I have a application that I'm going to launch remotely on 12 LAN computers at one time, but to activate the application, I need to press "r' on the keyboard. What code would I need so that I can run a .exe file through the command console that targets the process CapWiz.exe that is open and then mimics a keystroke on the keyboard "r".[code]....
The script should detect which key is pressed from the keyboard, including F keys; the script should start and when the user presses F2 should print something like "you pressed F2", when the user presses "A" should print "you pressed A", and so on

I'm trying to make a picturebox move left by 5 pixels when i press the left key. I am completely lost right now to be honest, and I've been trying to figure this out for the last 4 hours.

I was a professional software designer using VB6. Now that I've converted to VB2005 years later, use, with pages of unrelated information. With VB6 I could use Left$, Mid$, etc to parse keyboard input into a string. For example in the KeyPress event of a name box I could use
Case "A" To "Z"
CFName$ = Left$(CFNameBox.Text, CFNameBox.SelStart) + Key$ + Mid$(CFNameBox.Text, CFNameBox.SelStart + CFNameBox.SelLength + 1)
When converting a program from VB6 to VB2005 the software changed the line to
CFName = VB.Left(CFNameBox.Text, CFNameBox.SelectionStart) & Key & Mid(CFNameBox.Text, CFNameBox.SelectionStart + CFNameBox.SelectionLength + 1)
When writing another program I used the VB.Left(), etc, but it gives me an error. So, the question is, what is the correct way to capture keyboard input from text boxes and construct strings?

These work perfectly in the Windows/Desktop, but when I tried to use these in Games, the input from the program didn't seem to register, or rather registered in the background on the Desktop.
I plan on viewing the game through a webview control, which I believe is perfectly possible... unless I can't see Flash/Java content? I've been wondering how would you "simulate a click" in the web view control? And, of course, keyboard input?

I want to make an app which on loading sits in the system tray and even after I open another program (say notepad or vlc or anything) i.e. even when the app is not in focus and if I press "G" on my keyboard, the tray icon should show a tool tip - "key G is pressed". I have tried several codes but nothing works when the app goes out of focus. I can use Register Hot Key [url] but it needs a modifier also (like Ctrl or Alt etc. along with my key G). So, is there any way I can achieve this? something which many tray icons do like antivirus apps, etc. and I do not want to use AutoHotkey application.

I'm using a barcode reader which emulates a keyboard with swedish layout. I'm using RegisterRawInputDevices to create a lowlevel hook, catching windows messages and checking which device that sent the keyboard input. If it's the barcodereader, I would like to store the input. I receive the key input one by one in this class - how do I translate this into a string? If the character to be sent is an #, then the keys sent are Shift+3.

View 5 RepliesI am trying to develop a simple math calculator that will allow the user to input the right-hand-side (RHS) of an equation into a textbox on the application and have the application evaluate the expression for a given value of x, which is also input
into the application by the user via another textbox.For example, if the user wants to evaluate the following expression,
y = 3 + 4*x + 5*x^2
then they would input into the textbox the RHS of the equation
3 + 4*x + 5*x^2
and then enter a value of x into the another textbox and click on the calculate button.I tried this:
answer = EquationTextBox.Text
but it doesn't work.
i am trying to make a webbrowser in VB2010, but one major roadblock that has been in my way for a while, is the fact that i can't get my bookmarks bar to work
i have no code to show you and i am completely open to ideas as long as i use a toolstrip just make sure that the bookmarks work and they are Saved when the program is closed and opened again.
Notes:
instead of "WebBrowser1" use:
"
CType(TabControl1.SelectedTab.AttachedControl.Controls.Item(0), WebBrowser).PutWhateverHere()
"
(i am using a dotnetbar tabcontrol so i need the "AttachedControl")
the toolstrip i am using in this case is called "BookmarksBar" so please don't use "ToolStrip1"
I'm trying to create a custom keyboard for my accounting firm. I have all the buttons and button events sorted out.How can I make it so that when buttons a pressed, the text is input into where the cursor is? Currently i put the cursor for instance in an excel cell, then click the key on the virtual keyboard and nothing is inputted into the cell, i assume because it selects the keyboard window when i click the button. For some keys I'm also simply using:SendKeys.Send("q") for example.

So recently my Netbook keyboard stopped working, I got this new one. That would not be a problem if it was not for the missing [FN] key. My computer has several shortcuts, like FN + F6 = Turns screen off.
I cant seem to figure out how to bind these shortcuts to buttons in Visual Basic so I can just hit the button and turn the screen off that way, I've only used VB to make small simple fun stuff.
Visual basic 2008.I want to make an on screen keyboard exactly like the one in windows. I have made one which uses app activation, but that only works with the one you write in your codding or using a combobox to select one. How do you make one that works with everything like the one in windows.

It works to a certain point but i found out that the timer input multiple integers when pressing a key so I thought of about turning off the timer and then having the timer turn back on somehow but that is as close as i can get.
