i've written a win app using c# that automatically contacts to other applications such as browsers. i want to copy something in my win app, and paste it into the browser without involving user to click or move mouse. I don't have any problem with simulating mouse cliks, but i have problem to simulating keyboard strokes. Copy (Ctrl+c) always works properly, but when i want to paste whatever in the clipboard, sometimes works properly and sometimes doesn't. Follwing is more about my problem: I want to stroke Ctrl+v using C# ,in the other words I want to paste something in the Clipboard to another application using C#.

I am using the following code:

SendKeys.Send("^{v}");

I tried the following code too:

SendKeys.Send("^(v)");

But the problem is that it results sometimes paste action and sometimes just stroke v key. Can anyone help with what is wrong with my application? and another question, is it the problem to access clipboard when other apps want to access it?

What I have tried:

I am using the following code:

SendKeys.Send("^{v}");

I tried the following code too:

SendKeys.Send("^(v)");
