如何调用低级KeyHook组合键？

Question

I really can't solve this problem and don't even know, if it is possible.

I want to use CTRL+C and CTRL+V shortcuts.

Example: There is 2 Application. 1. App is written in C#, 2. App is an Java-Applet. I want to Copy string from C# App. and paste it into focused Textbox in Java-Applet.

I ll copy the string in to Clipboard and I need to Paste it into the focused Textbox in Java-Applet.

string data = "12345";
Clipboard.SetData(DataFormats.Text, (Object)data);

Now I need to paste this information into the Textbox in Applet.

How can I Call CTRL+V shortcuts in C#?

Is it possible to do something like that?

Thank You!

Answer 1

Another option would be to use InputSimulator which is a very flexible (and reliable) wrapper that is capable of simulating keyboard and mouse events.

It wraps SendInput under the hood but abstracts away all the PInvoke calls and other complexity. It's a drop in DLL that (for your situation) should only take a couple lines of code.

InputSimulator.SimulateKeyDown(VirtualKeyCode.CTRL);
InputSimulator.SimulateKeyPress(VirtualKeyCode.KEYS_V);
InputSimulator.SimulateKeyUp(VirtualKeyCode.CTRL);

or

InputSimulator.SimulateModifiedKeyStroke(VirtualKeyCode.CONTROL, VirtualKeyCode.VK_C);
