How can I change the insert/typeover mode of a text box?

By default, when I type into a text box, it inserts the text into the
existing text rather than overwriting the existing text. If I hit the
"insert" key on my keyboard, it switches the mode to over-writing the
text in the box. But when I refresh the page, it returns to inserting
the text. I want my text boxes to be in the overwrite mode by default.
Is there a way to do this in html or javascript. The solution only
needs to work for IE.
Thanks in advance.

For IE Windows it seems to work to call
document.execCo mmand('OverWrit e', false, true)
to enable overwrite mode for text controls on the page and
document.execCo mmand('OverWrit e', false, false)
to switch it off.
execCommand and its command strings (e.g. 'OverWrite') are documented on
With IE 5.5 and IE 6 you can have editable HTML controls too (e.g. with
<div contenteditable ="true">
I have not tested but I expect calling
document.execCo mmand('OverWrit e', false, true)
will switch on overwrite mode for those editable areas too so be careful
on when/where you call the command.

Hi I'd like to do the following with the FormView/ObjectDataSource but not sure of the best approach. 1. Change the FormView mode to Edit if a valid QueryString ID exists or Insert mode if it doesn't 2. If in Insert mode then when the form is posted it should get the new ID from the inserted record and change the FormView Mode to Edit 3. The SelectParameters ID must be updated too as it needs to get the new

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
