This should work
[DllImport("user32.dll", SetLastError = true)]
static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);
public const int KEYEVENTF_KEYDOWN = 0x0000; // New definition
public const int KEYEVENTF_EXTENDEDKEY = 0x0001; //Key down flag
public const int KEYEVENTF_KEYUP = 0x0002; //Key up flag
public const int VK_LCONTROL = 0xA2; //Left Control key code
public const int A = 0x41; //A key code
public const int C = 0x43; //C key code
public static void PressKeys()
{
// Hold Control down and press A
keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYDOWN, 0);
keybd_event(A, 0, KEYEVENTF_KEYDOWN, 0);
keybd_event(A, 0, KEYEVENTF_KEYUP, 0);
keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYUP, 0);
// Hold Control down and press C
keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYDOWN, 0);
keybd_event(C, 0, KEYEVENTF_KEYDOWN, 0);
keybd_event(C, 0, KEYEVENTF_KEYUP, 0);
keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYUP, 0);
}
You are able to fire the Cntrl-A + Cntrl-C event, am I right? But for some reason you are not copying all the webpage text to clipboard?
I don't know much about doing a Cntrl-A + Cntrl-C event, and I'm also not clear as to what u r trying to do, but I gave it my best shot and came up with something that grabs all the text from a webpage and copies it to the clipboard off of a button click event...(now obviously you would want to use ur Cntrl-A + Cntrl-C). Also for debugging purposes I put the clipboard text in a .txt file so you can double check.
I'm also using the HTML Agility Pack. You can get that from http://htmlagilitypack.codeplex.com/
CODE
private void btnClip_Click(object sender, EventArgs e)
{
string address = "http://animalrights.about.com/";
string text = "";
// Retrieve resource as a stream
Stream data = client.OpenRead(new Uri(address)); //client here is a WebClient
//create document
HtmlAgilityPack.HtmlDocument document = new HtmlAgilityPack.HtmlDocument();
document.Load(data);
//receive all the text fields
foreach (HtmlNode node in document.DocumentNode.SelectNodes("//child::p"))
{
text += node.InnerText + "\n\n";
}
Clipboard.SetText(text);
string path = @"C:\Users\David\Documents\Visual Studio 2012\Projects\CopyToClipBoard\CopyToClipBoard\bin\MyTest.txt";
// Delete the file if it exists.
if (File.Exists(path))
{
File.Delete(path);
}
// Create the file.
using (FileStream fs = File.Create(path, 1024))
{
Byte[] info = new UTF8Encoding(true).GetBytes(text);
// Add some information to the file.
fs.Write(info, 0, info.Length);
}
//destroy data object
data.Close();
data.Dispose();
}
Open notepad to check file
