 Posted: Sun Sep 27, 2009 8:02 pm Post subject: [C#] SendKeys unfocused |
 |
|
OK, I just want to know how to SendKeys to a specific application.
here is my code
| Code: | private void autoHPToolStripMenuItem_Click(object sender, EventArgs e)
{
IntPtr hWnd = FindWindow(null, "MyProcessName");
SendKeys.Send("{Q}");
} |
I want to know what im doing wrong... And how to make it stop when F1 key is pressed.
Please try to post the fixed code, since I have a hard time looking trough tons of pages...
Regards,
Alan Alvarez

It only sends keys to the active window, which should be obvious if you read the first couple hits on google.
| Quote: | | Because there is no managed method to activate another application, you can either use this class within the current application or use native Windows methods, such as FindWindow and SetForegroundWindow, to force focus on other applications. |
As for making it stop, just use a timer or spawn a thread that runs a loop until you press a certain key.

Ok, I got this...
| Code: | private void autoHPToolStripMenuItem_Click(object sender, EventArgs e)
{
Process[] processes = Process.GetProcessesByName("notepad");
foreach (Process p in processes)
{
do
{
SendKeys.Send("{Q}");
}
while ( ) // keypress code
}
} |
I want to know what to put in "while ( ) // keypress code"
Thank you!

Do you realize that you're not doing anything with that code?
It only sends to the active window, which you're not setting.
Use GetAsyncKeyState() for your hotkey.
http://www.pinvoke.net/default.aspx/user32/GetAsyncKeyState.html
Just spawn a timer or thread to check for it.
| Code: | if(GetAsyncKeyState(...))
{
//send a key
} |

Program will be made specifically for ONE game.
No need to be used outside the game.
thats why I use specific process.

lol i don't think you understand. slovach's tell you that this:
| Code: | | IntPtr hWnd = FindWindow(null, "MyProcessName"); |
is doing nothing. you're giving the variable hWnd a value, but you're not using it. use PostMessage if you want to send to a specific window. i really can't see the logic behind how you were thinking...

I am using this now...
| Code: | private void autoHPToolStripMenuItem_Click(object sender, EventArgs e)
{
Process[] processes = Process.GetProcessesByName("notepad");
foreach (Process p in processes)
{
do
{
Thread.Sleep(100);
SendKeys.Send("{Q}");
}
while (true); // keypress code
} |
But the application freezes when I execute it... :S

Ofcourse it freezes, you have an infinite loop in there... do you even know C# or coding at all?

 Did Dark Byte put a no being a dick head rule? Because, back in the day, someone would have came in and chewed your ass out and said "You need to go read the MSDN FIRST!!!!" or "Learn to code."

Urhm, not every game checks the messages that are sent.

Don't you understand the code? For each process that has the name "notepad.exe" it sends a "Q" to the active window. Also doing a do{ }while(true); will put the program into a infinite loop, that would explain the freezing since you're doing a constant loop on the program's main thread. I suggest you go to here: http://dotnetperls.com/backgroundworker or http://msdn.microsoft.com/en-us/library/aa645740%28VS.71%29.aspx.

and it would be a lot less painful if you actually read a book / tutorial that actually taught you.
