QUESTION
I'm doing a text editor based on RichTextBox. It has to handle complex formatting (BIU, colored text, etc). The problem is that all formatting tools are selection based, e.g. i have to select piece of text, format it, select next, etc.
it takes time, and it is visible for user.
is there a way to turn-off RichTextBox redraw, then do formatting, then turn-on redraw?
Or maybe any other way to handel complex formatting quickly?

...ANSWER
Answered 2019-Jun-10 at 13:16The reason you are getting an error is because it's a compile error. You cannot attempt to make the same object twice (or more) within a single batch, even if only 1 (or less) of those DDL statements would be run. For example even this produces an error, despite that neither INTO
could ever be be run (as 1 != 2 and 2 != 3):

Generally people store their public assets I.e Imgs/Js/Css at base level.
Eg /var/www/html/site/assets/images/
this means when referencing your assets you simply need to use ./images/logo_example.png
rather than hoping/worrying whether the assets will be in the right place relative the script you are running.
It also means when serving this code to the public you can secure your application code from any direct access while still allowing access to the assets.
So in short, move your images to the base /var/www/html/site/assets/images/
and from your script instead of:

Install biu
You can use biu like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
