Also, the user can drop text or other content, so t...

This is not the right answer by any means. Even if you don't like thehouse's answer, and considering this was written in 2009, it's completely non-cross platform. Use thehouse's answer - and if you don't like it then go for something like target_link_libraries(...
Why do we use Base64?
...nt bit. Furthermore the difference in line ending encodings across systems mean that the ASCII character 10 and 13 were also sometimes modified.
To solve these problems Base64 encoding was introduced. This allows you to encode aribtrary bytes to bytes which are known to be safe to send without gett...

“The Controls collection cannot be modified because the control contains code blocks”
...pahi It's actually pretty simple - using code blocks inside of a container means that you can no longer update Controls of that container. This basically exploits this behaviour by putting the code block in a separate container - so the error would only show up if you wanted to modify Controls of th...
Dynamic SQL - EXEC(@SQL) versus EXEC SP_EXECUTESQL(@SQL)
...x scan each time it is run.
