Annoying...

Code:

---

                        if(LOWORD(wParam) == BN_CLICKED && (HWND)lParam == hbtnGetHandle)
                        {
                                int input_len = GetWindowTextLength(htxtGetWindow);
                                TCHAR *pcBuf = new TCHAR[input_len];
                                GetWindowText(htxtGetWindow, pcBuf, input_len);
                                new_hwnd = NULL;
                                new_hwnd = FindWindow(NULL, pcBuf);
                               
                                if(new_hwnd == NULL)
                                {
                                        MessageBox(hwnd,"No window with that title found!" ,"Hrmmm..." ,
                                                MB_OK | MB_ICONEXCLAMATION);
                                }
                        }

Why does not this recognize the "string" pcBuf?? It seems like the result of the line where it is filled(pcBuf) does not do anything, because when I pass to FindWindow, nothing happend. Notice the check after, to see if a handle was actually found. When i run the program, it always pops up the Message box, meaning something went wrong. But what?? Would it be the TCHAR stuff?
Thanks for helping me fixing this :)

I have a working example if you want it.

Sorry that one isn't commented too well but the one on my computer is, just ask me and I'll mail it or upload it. :)

but I don't really understand what you are doing...this is what worked basically for me.

PHP Code:

---

char buffer[100];
GetWindowText(txtTitle, buffer, 100);
FindWindow(NULL, buffer);
//now you have your handle 


---

I think the problem is in here :

PHP Code:

---

new_hwnd = NULL;
                new_hwnd = FindWindow(NULL, pcBuf); 


---

try this:

PHP Code:

---

new_hwnd = NULL;
FindWindow(NULL, pcBuf);
sprintf(new_hwnd, pcBuf); 


---

Can you explain what this does? and apparently, i need a header with the declaration of sprintf. with the arguments, i think it is a conversion, but from what to what? Thanks

I looked in the msdn, and found the header, but when i run the program, it says:

Code:

---

C:\My Documents\VC++ Projects\WinProg\Handle Fun\h_fun.cpp(44) : error C2664: 'sprintf' : cannot convert parameter 1 from 'struct HWND__ *' to 'char *'
        Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
