I need to make combobox as readonly, but i didn't find any method like SetReadOnly() as in CEdit Class.

Is your combo box needing the "Drop List" style? (Check out the properties)

Yes, it's droplist.

If it is a drop list, it is already read only. What are you looking for?

I need to restrict the user from selecting from list in some cases. So i want to make it as readonly.

I think that you are wanting to disable the control. In that case, use this call: m_list.EnableWindow(false); where m_list is a control variable of your combo box control.

No. If i need to use EnableWindow() then i wouldn't have raised this question.

Let us consider the following
CEdit m_MyEditCtrl;

m_MyEditCtrl.SetReadOnly(TRUE);
m_MyEditCtrl.Enable Window(FALSE);

Would the about two stmts are same? please answer.

Edit control has a ReadOnly() method, because the user can type in some text. But the combo box (drop list style) just has a list of options to offer, from which the user can select one (he cannot modify anything, so there's no need for a ReadOnly() method).

Now, what you want the user "NOT" to do with your combo box?

I want the User to not to select any option from combo box but he can view.
It shouldn't be done through Enablewindow(false).
Because disabling means its not used at all.

In that case don't use a Combo box. Use a list box or list control.

Are you talking about Iain? Nobody can understand your problem properly until *you* explain it properly. If there's a fault, it's yours, please. Smile | :)

Yes. I still confused with the following answer given by him.

void CTestDlg::OnList_SelChange(void)
{
int iIndex = 0;

iIndex = m_ctrlList.GetCurSel();

if(iIndex == LB_ERR)
{
return;
}

if(iIndex == 3) // Suppose you do not want to select fourth item
{
m_ctrlList.SetCurSel(-1);
}
}

Please stop spamming. I've answered this question here[^]. Here's another chance to express yourself better: What exactly is that you want to do?

Did you forget your manners today?

Someone has kindly offered you a direction to look at for a solution, and that's the tanks they get?

You ask how to make the combobox readonly - you're told a drop list *is* read only.

You clarify that you know that, but you don't want the users changing selection.

Someone tells you how to stop that happening, by disabling the control.

You don't want that. You want the user to think "This app is broken. When I click on an item, nothing happens" instead of giving them useful visial cues.

This user shows you how to capture selection changing, and then rejecting it (ok, he made it no selection, but it's not hard to jump to reselecting the item you want), and you be rude to him.

Your's needing another shot of caffeine to withstand ingrates,

Iain.
