set edit box to read only

[acerunner316]

Hi, I am trying to set an edit box to read-only during runtime. I tried the two codes below, both caused the program to close. m)CEditData.SendMessage(ES_READONLY); and m_CEditData.SetReadOnly(TRUE); How can I toggle the read-only style without crashing? Thanks

Try calling the function CEdit::ModifyStyle and passing in ES_READONLY. See http://msdn2.microsoft.com/en-gb/library/0xhz2t1c(VS.80).aspx for ModifyStyle and http://msdn2.microsoft.com/en-us/library/f7yhsd2b(VS.80).aspx and look at the parameters for the CEdit::CreateFunction

also, make sure the control's HWND is created befory trying any methods to set the read-only style. Mark

What happens if you use of ModifyStyle instead SendMessage

Where it takes you in the code if you see callstack during debugging. There is no harm using these functions, if used this way,

m_ed.Create(WS_CHILD | WS_VISIBLE | WS_TABSTOP | WS_BORDER,
CRect(10, 10, 100, 100), this, 1);
m_ed.SetReadOnly(TRUE);
