Edit controls and WM_SETTEXT

[Joel]

I'm trying a new thing here.
I'm trying to get user input from console and send the data to notepad.

That part is done

Now, I'm making a method which using x and y coordinates of the edit control, will write the data...
any ideas how?

Right now, I'm using this:

Code

GeSHi (cpp):
#include <windows.h>
#include <iostream>
 
using std::cout;
using std::endl;
 
class ToNotepad
{
private:
    HWND m_hNotepad;
public:
    ToNotepad()
    {
        m_hNotepad = FindWindow (TEXT("Notepad"), NULL);
    }
    bool IsGood() const
    {
        return IsWindow (m_hNotepad) ? true : false;
    }
    void SendString (const TCHAR* data, int const x = 0, int const y = 0)
    {
        HWND m_hEditor = FindWindowEx(m_hNotepad, NULL, TEXT("Edit"), NULL);
        SendMessage (m_hEditor, WM_SETTEXT, NULL, reinterpret_cast<LPARAM>(data));
    }
protected:
};
 
int main()
{
    ToNotepad *pnp = new ToNotepad;
    if (pnp->IsGood())
    {
        cout << "Notepad located..." << endl;
        pnp->SendString(TEXT("Hola mundo"));
    }
    else
    {
        cout << "Notepad is not running..." << endl;
    }
    delete pnp;
    return 0;
}

Hmm, well I'm not entirely sure what you mean by

I'm making a method which using x and y coordinates of the edit control, will write the data...

However it's easy to get xy cords of an edit control from a window. for instance you can get a windows x,y cords using GetWindowRect()
But I am not really sure that this is what you are after, if i am right you want to get a window (specifically a edit control) from a screen point.
I have use a method for this in my "Kill" application (a program that you drag a red x over a window and it instantly terminates "kills" the application) but to be honest I really know 2 methods for this with a possible third. The first method (used in my kill app) is to use the api WindowFromPoint() in my "Kill" app I used SetCapture() and GetCursorPos() to get the mouse position, but you may be able to use GetCursorPos().
The other method would be to use a mouse hook inside a .dll, I'm not sure but there may be a method where you could use hooks without the .dll but I've never tried that. If you like I can post the source to my "Kill" app (warning it's in ASM) but it may still give you ideas of how to do this.

Thanks FK...let me explain a little bit.

I'm trying to write some string into the editor of notepad using x position and y values..
I think is also called it cols and rows position, based on the EDIT control.

Hmm, I had to do a little research for this one. Try taking a look at the following messages.
EM_CHARFROMPOS
EM_LINEFROMCHAR
EM_POSFROMCHAR
those are what i found for now i'll try to look-up the edit control subclass messages and see if there is anything there when i have time.
