[Dev-C++] Getting Text

[Jarren L. <vb...@gm...>]

Hey everyone. I need to be able to get the text from an edit control
after I click a button. Here'swhat I have so far:

    case WM_CREATE:
        button=3DCreateWindowEx(0,"BUTTON","Graph",WS_CHILD|WS_VISIBLE|BS_D=
EFPUSHBUTTON,
        0,0,100,17,hwnd,NULL,g_hInst,NULL);
        entry=3DCreateWindowEx(WS_EX_CLIENTEDGE,"EDIT","Function",
        WS_CHILD|WS_VISIBLE|WS_BORDER,100,0,99,17,hwnd,NULL,g_hInst,NULL);
        break;

How would I go about getting the text from the edit control after I
click the button?

look at this tutorial http://www.winprog.org/tutorial/
you will find this function

BOOL SaveTextFileFromEdit(HWND hEdit, LPCTSTR pszFileName)
{
    HANDLE hFile;
    BOOL bSuccess =3D FALSE;

    hFile =3D CreateFile(pszFileName, GENERIC_WRITE, 0, NULL,
        CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);

    if(hFile !=3D INVALID_HANDLE_VALUE)
    {
        DWORD dwTextLength;

        dwTextLength =3D GetWindowTextLength(hEdit);
        // No need to bother if there's no text.
        if(dwTextLength > 0)
        {
            LPSTR pszText;
            DWORD dwBufferSize =3D dwTextLength + 1;

            pszText =3D (LPSTR)GlobalAlloc(GPTR, dwBufferSize);
            if(pszText !=3D NULL)
            {
                if(GetWindowText(hEdit, pszText, dwBufferSize))
                {
                    DWORD dwWritten;

                    if(WriteFile(hFile, pszText, dwTextLength, &dwWritten=
,
NULL))

                       bSuccess =3D TRUE;
                }
                GlobalFree(pszText);
            }
        }
        CloseHandle(hFile);
    }
    return bSuccess;
}
