Inside the application there is an if statement. It checks a string variable kai if the variable equals to 1 i want it to react as if i pressed the right arrow on my keyboard. Can you help me with that? Thanks.
Actually you might want to think about using Commands for that. If you think about what you want to achieve it is to trigger something after the Key-Press. If you use a Command for that you can directly trigger it without going via the programmatic key pressing stuff. Also you can still trigger the command via a keypress (InputGesture).
You can find out more about Commands here: http://msdn.microsoft.com/en-us/library/system.windows.input.icommand.aspx
maybe like this:
SendKey.Send({rigth});
set focus to the control you want to input before.
And you ave to declare
Using System.Windows.Form

I've been trying to figure out how to get multiple key strokes with a single command. The goal is to have an effect like:
SendKeys.Send({"TAB"}{"TAB"}{"ENTER"}{"TAB"}{"ENTER"}{"TAB"}{"ENTER"});
I've been able to get two key strokes to work such as
SendKeys.Send(^{"TAB"})
However this is press and hold control + press tab. The goal I want is not to hold down a key then press, but to have the button press register multiple times. Thank You!
SendKeys supports sending multiple keys. Why are you using incorrect syntax there? It should really be like:
SendKeys.Send("{TAB}{TAB}{ENTER}{TAB}{ENTER}{TAB}{ENTER}");
Try using SendWait instead
SendKeys.SendWait("{TAB}{TAB}{ENTER}{TAB}");
This will ensure each keystroke is processed first before sending the next and seems to have the desired effect
I am developing the Internet Explorer Toolbar in c#.net using the band objects.
Now in my toolbar, I am using the textbox field to make the search enable, but in this textbox field, I am not able to use the backspace, delete, arrow keys and many other such button.
I am not sure about y I am not able to use this. Please help me about this. I found many question posted over like this, but none of them was having the specific answer.
Thanks
The problem is that the browser is eating the events for those keystrokes, so the solution is to force focus to the toolbar when the text box receives focus.
To fix it add this line to your toolbar's constructor:
yourTextBox.GotFocus += (sender, args) => OnGotFocus(args);
Also make sure you have implemented TranslateAcceleratorIO() per this example.
Compare your code to this one and see what's missing.
Please guide me as how to save/discard values of controls of a form, upon pressing Ok/Cancel button accordingly in Visual Studio C#?
Controls in a form include TablelayoutPanel(TextBoxes), NumericUpDown.
Need your expert guidance

With both of your buttons, inside the "onclick" event, call a function that will save the content of the form. You also need this call in the "onclose" event of the form, in case the user presses the top-right X button (or not, if you dont want data to be saved at that moment)
Inside that function, you will need some code that will save data to the registry.
Writing in the registry is easy. This webpage also explain how to get the data back. The values you will write will be the textbox.Value and such
The question isn't clear, but in a WinForm you can call
this.Close()
on the Click event of your Close button.
Every object or variable used by the form will be destroyed. Be careful! running background threads will still be alive until they terminate.
About saving the status of your variables it completely depends on what you need to with them after; you can either keep them in memory and pass them around like parameters or write on a disk (maybe with serialization?).
We need to know more.

You may want to take a look at Application Configuration ( http://msdn.microsoft.com/en-us/library/ms184658(VS.80).aspx ).
I would like to be able to programmatically emulate the keyboard
navigation for dialog boxes.
I have a custom hardware device with a keypad that I would like to use for
dialog box navigation.
I know about Focus(), but I'd rather do something that automatically
respected the tab order. By emulating the keyboard navigation I don't
have to worry about re-inventing complex behavior for each type of
control.
Does anyone know how to do this?
Thanks!
For Winforms, you want want the Control.GetNextControl() method
For WPF, you want the UIElement.MoveFocus() method
In Winforms:
Control nextControl = this.GetNextControl(myControl, true);
To simulate a tab press, I believe it's the following:
SendKeys.Send("{TAB}");
You could use P/Invoke to call the Windows API function keybd_event to simulate pressing the Tab key.
Bonus: you can use your device to enter tabs into a text editor as well! ;)
I want the 'Alt' to be pressed by code. It is like firing key-press event with key 'Alt' by the code, not hitting it manually. The need is, I have set 'ShortCut keys for menu, but it (the single underline on key letter) is not visible to the user unless he presses 'alt'. So i need to make the Alt be pressed by default.
Is there a way to 'press' or 'fireup' the keys in key board using c# code?
Check out the System.Windows.Forms.SendKeys class.
You can use the static Send method to send keystrokes to the active window. If you're trying to send keystrokes to another window, you'll need to use the Windows API to activate the other window first.
If you have any control over the operating system on which the program is being deployed, apparently you can force the underlined shortcut letter to always be displayed by going to Control Panel -> Display -> Appearance -> Effects -> Hide underlined letters for keyboard navigation.

here is a complete article on use of SendKeys on codeproject
Here is how you simulate input (both mouse and keyboard).

If you look at the System.Windows.Forms.SendKeys class you will see that it provides you with what you want.
