How can I make this print the text in the edit box when you push the button instead of "You pushed a button." I have looked all over but I can't figure it out.

If you look at line 137 it calles the MessageBox function which takes the arguments MessageBox(<message to show>, <title>, <buttons to show>, <icon to show>)

delete Entry [];

I'm pretty rusty at C++, so note useage of NEW & DELETE

Thanks I got it working using this code:

int TxtSize = GetWindowTextLength (hWndEditBox) + 1;
char *Entry = new char [TxtSize];
GetWindowText (hWndEditBox, Entry, TxtSize);
MessageBox (NULL, Entry, "", MB_OK | MB_ICONINFORMATION);
delete[] Entry;
