When I downloaded FileZilla, somehow I also got Chromium and some TV something downloaded and installed under Win10. I removed the TV crap, really no need, but I was thinking to keep Chromium since I need to test my websites with it once in a while. Cool, but that stupid software installed itself to auto-start!!!
I don't think I had the option to NOT have such a feature turned on.
So... I had to search for it because apparently no one knows how to handle Auto-Start features under newer versions of MS-Windows. It is actually... take a deep breath... in the Task Manager. (At least in ...
Today I was confronted with an error in a process that would run in the background and slowly fill up the Windows message queue when it should have been dormant.
I looked at the messages that were being processed once the process woke up and the message number was 0xC10C or so. Nothing in the software has such a number. So I looked around and found out that the message was one of those created using the RegisterWindowMessage() function. (This is wrong in that application since the messages are never used from external applications, but oh well... that does not change the basic problem.)
I recalled reading somewhere that you could see the performance of NVidia cards under MS-Windows. Looking around I could not really see how that would be done. Today, though, I found out that perfmon does it all!
To start perfmon, click on your Start button and enter perfmon and click Run. You may also start it from a command line although perfmon is a graphical tool.
Once in there, click on ":Performance Monitor", it should appear under Monitoring Tools.
That won't give you the GPU information though, not by default.
When you right click on the area with the graph, you see ...
As I was working on a MS-Windows installation, I ran in this weird error: Data source not found and no default driver specified...
This was output when I was running the following in a command line prompt:
The result should have been an MSSQL prompt instead!
The problem on the computer was that I uninstalled MSSQL 2005 that was automatically installed by Visual Studio C++ and was not compatible with our application, so I first uninstalled that but that uninstallation is really not proper. It leaves a LOT of things behind.
After that I installed MSSQL 2014 which was reported as ...
As I am working on my as2js compiler, I stumble on a couple of problems with the for() loop parsing because of the in keyword. That made me think and the for() statement was actually a very funny one. Yes! You can actually write something like this and it compiles:
int zero; for(3;2;1) zero;
As you can see, all 3 entries in the for() statement are valid expressions and therefore the compiler can compile that code. This creates a loop that runs forever, similar to:
but much less clear to read, obviously.
Now that's food for thought, isn't it?
If you are like me and write DTDs to check your XML files to make sure you don't have too many mistakes in them, then you probably have had this problem before.
The #PCDATA has a very special behavior and it is really restrained as follow:
Something like this:
<!ELEMENT Z (P | (#PCDATA | A | B | C)* | Q)+>
does not work because you use + and #PCDATA is within a sub-group.
What you need ...
Today I opened a document where I had to make a few edits and LibreOffice decided to tell me:
Readonly content cannot be changed.
No modifications will be accepted.
There is a screenshot of that message:
The error may be justified, I do not know, but apparently not too many people know how to unlock a document. I found pages and pages that tell people to check the read/write protection of the file, as if a read-only file on disk could not be updated in the editor... (yes! you cannot write it back, but you can edit it and do a Save As ...)
One person, though, had the correct answer to ...
I have used several different software to gain remote access to other's computers.
With a Unix system, it's easy. You use ssh and you can do everything you want (although some people just cannot handle a console, I'm fine with such, but ssh allows you to access X-Windows if you'd like with the -X command line option.)
With MS-Windows, since that system is just a desktop application, you need a special tool in order to achieve that feat. Most of them are for money or make use of things that do not work under Linux. Yet, there is one that I like, it is called TeamViewer. It was ...
In the last few days I've been trying to find the reason for a slowness in one very specific case in a software. It looks like it crashes and since it includes many try/catch with (...) it certainly captures the fact, but contrary to what it is expected to do, this one does not get logged! In any event, I wanted to prove that the area where we first were looking was not affected, and sure enough it was not. The problem is somewhere else. However, to prove that I needed to have a way to log milli-seconds because things happen very fast and a 1 second decimation is definitively not enough.
Today I ran in a problem where I created a new form and the sub-form inside that form would auto-resize itself. Strangely enough, all my other forms also have a sub-form and that sub-form is not auto-resized... so what gives?!
I did not find anything about preventing an auto-resize of a sub-form. Found many pages on the net about how to write code to resize a form "manually". But that really did not help.
As I created that new form, I marked it as "Auto Resize" to No. This seems logical if you do not want a form to get resized. Think again! The ...

Very Secure File Transfer Protocol Daemon, an FTP server that allows people to transfer data between computers. It is marked as very secure, at least it is as secure as an FTP server can be (although there has been several security advisories for this tool...)
Remember that an FTP transfer is rarely using an encrypted pipe (it is possible to use kerberos and SSL to really secure the data transmission) and also because it uses a data stream opened dynamically, it is possible for hackers to spoof a data connection.
