Is there any way to increase the resolution of images posted, currently they are far to small to be usable?
😎 - Eirikur Eiriksson - Friday, January 20, 2017 8:43 AM
It would be nice to be able to adjust the resolution of images as one is posting too.

Zounds. The SQL Code IFCode windows are pretty much a train wreck now. If I copy and paste from SSMS, indentation (leading spaces) disappears and double, triple, and, sometimes, quadruple spacing occurs. If I copy and paste to Notepad and then copy and paste from Notepad to the IFCode, the indentation and line spacing is fine but the colors make absolutely no sense at all. All vestiges of correct coloration of dynamic SQL are all but lost.
Here's some of the latest code I tried to post using the SQL Code IFCode. The first one is a paste directly from SSMS and the second one is a paste from Notepad. To be sure, we shouldn't have to go through Notepad. The copy and paste from SSMS should work.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.Change is inevitable... Change for the better is not.

Interestingly, I get a very different paste when I do it from SSMS (as I highlighted in my earlier post). I've used Jeff's Notepad paste and put it into SSMS, then copied and pasted that into SSC. As you can see, you get something different again! (Notice the allignments are all over the place). I actually lose whitespace, instead of gaining it.I am using Firefox 50.1, and Windows 7 here. Also, the cursor bug still exists it seems, that's really annoying. Especially when pasting (as it either loses focus, or just end up somewhere random), and half the time is one character behind where you type. Considering my posts are riddled with typoes as it is (yeah, my bad), it makes them a real pain to fix them, as backspace doesn't delete the characters it should! >_<

There seems to be something wrong with posting quotes.
Works fine when I try here, but exactly the same thing doesn't work properly in another thread: https://www.sqlservercentral.com/Forums/FindPost1852973.aspx
Definitely something odd going on with quotes:

What the heck?
The "Above is cut-n-paste is from SSMS" was originally all on one line when I first wrote the post. It should not have cracked the line like that. And when I went back to edit mode to fix the line, it wouldn't let me backspace from cut-n-paste to move up to the line above with the "Above is". In fact, it deleted the "c" and then just stayed stuck.
What's going on with that?

Thanks Brandie, We're looking into this. It looks like IE is doing some strange things with formatting and is preserving formatting between SSMS and IE which then gets wrapped in a further format with the IFCode.

Don't worry, I'm in the middle of making a Poll where you can vote about what's better; my linkedIn profile, a local furniture store, or a website you can illegally watch American Football games on. I'll ensure to include links to all websites in the Poll results and questions ^_^

Don't worry, Luis. It's always some season somewhere. I'm sure some sports organization will have something to post. The cheap kitchens and muscle-building supplements won't monopolize the spam.
