The docs for garbage collection explain how to set the garbage collection policies with cbt but don't explain how to read the policies. The cbt reference doesn't seem to have any command to get garbage collection either. As far as I can tell, this isn't available in the GUI.
...ANSWER
Answered 2021-May-25 at 00:28See this page about configuring garbage collection. It provides examples of how to set and update garbage-collection policies when you use Cloud Bigtable client libraries or the cbt command-line tool.
The answer to your question is that you can view garbage collection policies of certain tables by running this cbt command:

QUESTION
I have a GridView where the datasource is set from a Datatable filled from a Stored Procedure. There are two columns in the datatable that I am interested in filtering/showing & hiding based on their content. The data is for lessons for different courses.
DataTable/Datasource
Identifier Lesson Title BaseIdentifier CBT-0001 How to Build a Cabinet CBT-0001 CBT-0002 Dangers of Cutting Lumber CBT-0002 TBL-0001 How to Build a Table TBL-0001 TBL-0002 Dangers of Cutting Lumber CBT-0002In the above table the Lesson TBL-0002 is just a alias/ pointer to CBT-0002.
Based on a checkbox I need to show everything in the Gridview and I need to just show the parent lessons the ones where the identifier = baseIdentifier. So after filtering / or hiding rows my gridview would look like this:
[ ] Show Alias Lessons
Identifier Lesson Title BaseIdentifier CBT-0001 How to Build a Cabinet CBT-0001 CBT-0002 Dangers of Cutting Lumber CBT-0002 TBL-0001 How to Build a Table TBL-0001[X] Show Alias Lessons

The only time an Identifier will equal a BaseIdentifier is when it is the parent lesson (Parents are Aliases of themselves).

I am trying to make a set of input boxes next to each other and I can't get it to work. I am trying to get the left side to stay on the left side and the right side to be even with the left side.

QUESTION
I'm struggling to find the best way to centre my text in the middle of the image (vertically and horizontally). The problem I'm having I think is that the image I have set has a min-height property. The min height property changes in tablet and mobile compared to desktop. Can anyone think of a solution to centre it and have it be responsive?

QUESTION
I have this code to log into cbt nuggets and afterwards i want to go into my playlists and collect some URLs
...ANSWER
Answered 2020-Dec-09 at 08:20Have you tried to parse the login result? This might happen because the login request is not fully processed yet.
After Login_Button.click()
you should check if the site is logged in successfully or not. You have many ways to check:
- If the site redirects: check for the title of the page
- If the site display a dialog: create a fluent wait to check for the dialog element to display
- If you don't even bother to check, just add
time.sleep(5)
. It's bad practice though.
After the check, now you use driver.get
to go to the page you want.
QUESTION
I am relatively new to C++. I have a question why the program posted below behaves the way it does when the constant DEMOMETHOD is set to 1 in main.cpp and button_class.h.
The program demonstrates subclassing a few buttons created by a single c++ class - there are 4 instances of the class (4 buttons) and two (labeled button1 and button2) are subclassed.
I'm hoping to learn:
- why return 0; is needed in the handler of the wm_lbuttondown message in button_class.cpp for multiinstance subclassing to work correctly (set DEMOMETHOD = 0 for correct program operation).
- why the other subclassed buttons and the non subclassed buttons work incorrectly after either one of the two subclassed buttons are clicked. Example: the quit button doesn't work if you first click on Button 2 (or 1) when DEMOMETHOD = 1.
I posted compilable (gcc compiler, Windows 7) code to make it easier to observe the behavior I saw and to, hopefully, help other new c++ programmers that stumble upon this post.
Thanks in advance.
...ANSWER
Answered 2020-Dec-07 at 01:42In fact, these two problems are caused by the same problem. When you use return 0
, you will return directly without calling the DefSubclassProc
function outside of switch
.
If you use break
, you will jump out switch
, call the DefSubclassProc
function again. This is why the same button is triggered continuously when the DEMOMETHOD
value is 1.
So the solution is very simple, you just need to modify the following code:
