Another Edit question

What im trying to do is when the user changes something in an edit box i want the edit box to be be set to something so i was just trying to test this thing out but when i do it, my program just goes away. Here's the code

Code:

---


case ID_MAG_MIN:       
       
SendMessage(GetDlgItem(hwnd,ID_MAG_MIN),WM_SETTEXT,0,"34.0");

break;

---

>>when the user changes something in an edit box<<

Handle the EN_CHANGE notification (as HIWORD(wParam) of the parent's WM_COMMAND).

do u have an example of how to do it. i tried this, but it didnt work...

Code:

---


case EN_CHANGE:
                        switch(HIWORD(wParam))
                        {
                        case ID_MAG_MIN:
                                SendMessage(GetDlgItem(hwnd,ID_MAG_MIN),WM_SETTEXT,0,"34.0");
                                break;



                        }

EN_CHANGE is delivered in a WM_COMMAND message. Ken has posted code before demonstrating how to handle WM_COMMAND messages:

I dont understand how to code EN_CHANGE as a HIWORD param, i mean i was thinkin

EN_CHANGE=HIWORD(param), but i got an error doing that

i figured it out, so thanks everyone!
