Hi,

I thought about writing about a common thread deadlocking problem with Windows Forms.

I do use the Google to search solutions to my programming “problems”, but this solution I actually had to use my own brain😳

If the thread uses invokes to the GUI thread to delegate something to be done on the main thread the application’s message pump sort starts. This may result that when you close your program the simple Thread.Join() deadlocks.

So the simple solution is to do the message pumping until the thread joins:

while (!aThread.Join(1000)) // we wait for a second, then let the main thread do the message pumping..
{
  Application.DoEvents();
}

 Have a nice weekend..

.. and sorry if the English gets too complicated as the native language of me is Finnish – as:

Moi,

Ajattelin kirjoittaa yleisestä ongelmasta, jossa säie estää toisen säikeen toiminnan Windows Formsin kanssa.

Yleensä käytän Googlea etsiäkseni ratkaisuja ohjelmointi-“ongelmiini”, mutta tämän keksimiseen piti käyttää omia aivoja😳

Kun säie blokkaa pääsäikeen, pitää käyttää pääsäikeen viestipumppua ja kutsua Thread.Join() -metodia aikaviiveellä.

Hyvää viikonloppua..

Hi,

It seems that I have a SEO (Search Engine Optimization) service. Weird that I keep getting these messages about two to ten “notifications” / year. I would advise not to take any action regrading to these emails.

Of course I do not have such service account and the location from whence these emails come seem to be questionable… However as I get one bill / year of owning the domain it might look like a bill you would just accept to be  a warning that I forgot to pay 🔒 The spammer seems to use whois database to send these emails. So, just to give an advice, do not give them any money 😎.

Now I might be breaking the “law” as I publish parts of message… i did some editing however, but if you wish, the information is available somewhere..

Thunderbird seems to “think” this is a junk mail – for some unknown reason – haha 😯

And the breaking the “law” part (the small print):

As we see this was not a bill after all.. have fun again and I’ll be back with some bug fixes in a some period of time..

Hi,

I recently wanted to log internet outages (ISP) so I wrote this script. The script it self has no license – so call it a free to modify, publish and use. I did set the script to run every five minutes via cron.

The code:

#!/bin/bash

current_date_time="`date "+%Y-%m-%d %H:%M:%S"`";

curl --head http://www.google.com > /dev/null 2>&1
OUT=$?

last_msg_start=""

if [ -e /var/log/ISP_Log ]
then
    last_msg_start="`sed -n '$,$ p' /var/log/ISP_Log | cut -c1-16`"
fi

if [ $OUT -eq 0 ]
then
    if [ "$last_msg_start" != "CONNECTION:[YES]" ]
    then
      echo "CONNECTION:[YES] $current_date_time" >> /var/log/ISP_Log
    fi
else
    if [ "$last_msg_start" == "CONNECTION:[YES]" ]
    then
      echo "CONNECTION:[N/A] $current_date_time" >> /var/log/ISP_Log
    fi
fi

sed '1,500 d' /var/log/ISP_Log

The log file contents:

CONNECTION:[YES] 2017-08-09 19:03:29
CONNECTION:[N/A] 2017-08-11 21:10:01
CONNECTION:[YES] 2017-08-11 21:15:02
CONNECTION:[N/A] 2017-08-12 20:40:01
CONNECTION:[YES] 2017-08-13 10:45:01

As I have previously done, all the C# code is documented with XML documentation (private/public) and sort of vowed to do so in the future.

Sometimes this is the most boring part of the programming procedure as I have been commenting my recent library for a week now 🤷‍♂️ … about a minute to a hour per day. See – Incredible MOTIVATION!

Well, soon another library will be released fully documented..

I’ll be back soon..

Hi everyone,

In a summer holiday sometimes you have time to do some “serious” programming..

This time it is a sort of a Task Manager, which also watches file system changes and it will probably spawn some libraries which will be published here too.

Do note that this is still a work in progress.

I’ll be back 😛

Hi,

Even though you have a high-end desktop PC and numerous software installations to help sometimes you just need pen and paper to visualize some “complex?” stuff.

This paper was used when I was developing the first version of SunMoonCalendar. The paper seems to be covered with cat hair (four cats) 😀, coffee cup markings and a few cat paw markings with dirt as they do like to go outside from a window to a cat pen to hang around.

One of four cat’s

By the way I’m called “Señorita” 😛

It seem’s my no thanks to -list is now empty as the release of IZArc v.4.2 malware/adware has been removed from the software (I scanned and checked).

Must find new enemies 😇

Hi,

I recently found a bug in my software because it was using a custom date time format string DateTime.Now.ToString(“yyyy-MM-dd HH:mm:ss.fff”), which should lead to a date time string like this “2016-01-16 09:47:00.045”.

The time separator “:” however is not absolute, it can output a character such as “.”. So learning from the mistake the previous piece of code is now DateTime.Now.ToString(“yyyy-MM-dd HH’:’mm’:’ss.fff”). This makes the time separator absolute.
