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.

View 2 RepliesI 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?
I used to program in BASIC, and am trying to learn VB now.

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?
View 2 RepliesI 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.
View 2 RepliesI'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.

Lets say I have 20 lines like this. I want to change this lines according to user input. So user will input how many lines they want to change in terms of row and column. In my program
Row=TextBox5.Text column=TextBox6.text
User must enter initial value for x and y. Let say the initial value is
x=1 y=1.
Row=2 column=5..
Now my lines should look like this.
1 1
2 1

View 1 RepliesI am building an image processing program. As part of this, I have a picturebox, set to AutoSize.
When I load an image larger than the size of the picturebox's container the box automatically expands and shows scroll bars. This is what I want. I can scroll the picturebox using the mouse to click on these, but I would like to be able to scroll the image using the arrow keys. This poses a couple of problems:
1) finding what properties to change or events to raise when a key is pressed. It is a property of the picturbox, or a property of the container?
2) dealing with repeated scrolling while the arrow keys are held. I know I can use keydown to detect that an arrow key has been pressed, but how do I continue to scroll as long as the key is held down?
