Often this is due to the new connection dialog being off screen (usually due to changing monitor setup e.g. 1 to 2 monitors or resolution change etc). If so the really easy fix (if your connection dialog just needed approval without changing fields) is : Focus on SSMS and Hit Enter/Return ..or the easy fix … Read more

In the tutorial posted it below, they did not mention I should use post.releaseConnection(); It caused my code to hangup, so I addeded the releaseConnection() function after every POST/GET. I hope that is the proper way to clean the code up.
system() simply passes its argument to the shell (on Unix-like systems, usually /bin/sh). Try this: int a = system(“python -m plotter &”); Of course the value returned by system() won’t be the exit status of the python script, since it won’t have finished yet. This is likely to work only on Unix-like systems (probably including … Read more
You must be as fast as possible in your onClick implementation. Expensive operations should be, in general, offloaded to a background thread. In onClick, try: Thread t = new Thread(){ public void run(){ your_stuff(); } }; t.start(); instead of just your_stuff()
I guess that the optimizer is fooled by the lack of ‘volatile’ keyword on the isComplete variable. Of course, you cannot add it, because it’s a local variable. And of course, since it is a local variable, it should not be needed at all, because locals are kept on stack and they are naturally always … Read more
I ran into the same SQLite/Postgres problem with Flask and SQLAlchemy, similar to Gordon Fierce. However, my solution was different. Postgres is strict about table locks and connections, so explicitly closing the session connection on teardown solved the problem for me. My working code: @pytest.yield_fixture(scope=”function”) def db(app): # app is an instance of a flask … Read more
This problem occurring most usually at Joomla 3.x. To solve this go to wamp\www\Your joomla folder\installation\sql\mysql and open Joomla.sql file find the term “ENGINE=InnoDB” and replace ALL with “ENGINE=MyIsam” MyIsam is more supported and compatible with Joomla. Do also the same with (sample_data.sql) file, if it’s quickstart setup.
A good bit of time has passed since I originally posted this question. I’ll answer it myself in case my mistake can assist anyone. I never got a “solution” to the original problem. At a much later date I switched across to the npm release of the sdk and it worked. But before that time … Read more
You might be interested in my experiences with Freezable: I once wrote a PDF viewer using muPdf which renders bitmaps, that I render with WPF. What helps performance greatly is that I can render the page bitmaps on a background thread, freeze them, and then pass them to the UI thread. It is nice that … Read more
