Not unless you need some functionality that it provides that a regular edit control does not.

You've not provided any requirements that warrant a richedit control. A regular edit control will work just fine.

I think your problem can be solved in both cases. Both of Edit or Rich Edit controls have such programmatic feature.

If you define a m_cMyEdit control variable for your edit control, then you can delete the selected text using this call:

m_cMyEdit.ReplaceSel("");

Add the above line in the handler for your Delete button.

It will work when something is selected. If your Delete button should delete entire content when nothing is selected, you can try this:

int start, end;
m_cMyEdit.GetSel(start, end);
if( start == end)
{
    // nothing selected; delete all
    m_cMyEdit.SetWindowText("");
}
else
{
    m_cMyEdit.ReplaceSel("");
}

In order to understand the new problem, can you give more details, maybe a sample.

again take 0123456789.we delete 6789 using ur code.after that i want to enter some more numbers so i click button 1.so it should display 0123451 but it is like 01234567891.
means it's not deleting in buffer.
this is my problem.

Perhaps the code for your button 1 actually does not insert a single character, but inserts the full string from a variable. Can you check what happens in your code when you click on numeric buttons?

thank u,
same problem,
what i mean button1 means button contains label 1

Viorel.13-Jun-06 3:16

Re: simple problem for experts like u [modified]

The button 1 seems to be a button control, and I think it contains some code associated with it. You should see which function is executed in your code when you click the "1" button, i.e. how the text is inserted into edit control.

in button one my code is like

m_text +="1";
UpdateData(false);

where m_text is member variable for edit box

Therefore the Windows works fine, but not how you expected. I think the handler for button 1 should be changed to:

m_cMyEdit.ReplaceSel("1");

where m_cMyEdit is the control variable of your edit control.

Try this first for button 1, then -- if works -- adjust all of your numeric buttons.

Associate the Control variable to your Edit Control and Use the methods like cut for deleting the selected text.
