Well, I'm back ... I've written a couple of articles about ESE, the no sql database engine included with Windows.

Hi Mika, nice to see that you are still around, btw. nice answer :-)

Agree, I didn't read your entire answer until after I made the same recommendation with regard to Petzolds book ...

Espen Harlinn 13-Jul-17 19:30pm View

Did you remember to call fclose on the handle before exiting the program?
You can also drop CString and call sprintf on your buffer (my_rec.sequence) directly - then the call to Widechartomultibyte will not be required as sprintf works with char and not wchar_t ...

Espen Harlinn 13-Sep-16 5:36am View

Just below fileStram.Read ... that's the part that transfers the data from the file into a memory buffer usable by the Application.

Espen Harlinn 23-Mar-16 6:36am View

Trekking is a brilliant way to spend your holidays - this year we went trekking into the mountains surrounding Voss here in Norway.

I haven't seen that movie, and I've never visited a country fair like the one you're describing - and it sounds like something we would enjoy though.

Espen Harlinn 30-Sep-14 18:12pm View

>> Ah... Congratulations... I guess
No need to guess: http://www.powel.com

>> Do you mean you're supposed to move?
Yes - we will be moving to Trondheim.

Powel is a spin-off from the Norwegian Electric Power Research Institute (EFI), and used to be a part of the SINTEF Group, which is, by far, the largest research organization here in Norway.

>> but they give me about a month
Good for you :-)

>> due to important reason: next agricultural fair
Now I'm getting curious ...

Espen Harlinn 30-Sep-14 17:28pm View

Just had a much needed 3 week holiday, and this is my last day at Goodtech :-)

Tomorrow will be my first official day as chief architect at Powel - I've been working with them for more than a year now - and it's been a great experience. So now we're looking for a decent place to live in Trondheim.

I sincerely hope all is well with you and that you're having a good time too.

I'm now working for a company, Powel, in Trondheim - acquiring some frequent flyer miles. It's a really nice company - lots of decent people.

I will be joining them on a permanent basis as chief architect this autumn - so eventually we will be moving there.

I enjoyed your PoIP article - well done - I assume you've allready implemented this for smartphones :)

Espen Harlinn 6-Nov-13 15:31pm View

Which is why I mentioned that you have a good point :-)
Now, with regular laser or inkjet priners you sometimes run into problems with anti-aliasing, and every once in a while you print out a barcode that can't be read back by the scanner. A professional barcode printer reduces that problem significantly, and for many applications an unreadable barcode every once in a while isn't that much of a problem - but when it is, you need to use a real barcode printer.

Espen Harlinn 23-Oct-13 9:37am View

I don't think that you run into that limit using AFS - it has, reportedly, been used on quite large installations - involving a very large number of computers, many of them running non-server versions of Windows.

>> not even touching the possibility of running
>> workstations out of disk space by accident
Now, that's an entirely different problem ;)

Espen Harlinn 22-Oct-13 17:35pm View

Thanks Sergey - OpenAFS is a gem, and it's highly useful when you have an environment that includes a plethora of operating systems.

Espen Harlinn 22-Oct-13 17:25pm View

5'ed! DFS is certainly an option - you will probably like to have a look at: OpenAFS for Windows, as it's not as limited as DFS when used with the non-server versions of Windows.

Espen Harlinn 22-Oct-13 17:07pm View

Pseudo code generally doesn't teach you much - in a way, it's often, a trap that fools you into thinking that something is easier than it actually is.

By studying real applications you get a feel for the amount of work that's required when you also have to implement the stuff that has to be part of most applications, even if it wouldn't usually show up as part of any pseudo code that only highlights a few major points related to the workings of the application.

Espen Harlinn 10-Sep-13 13:45pm View

Espen Harlinn 10-Sep-13 5:46am View

True, unless he installed one for development purposes ...

Espen Harlinn 9-Sep-13 16:26pm View

Yes, the exception is a fair indication that the cast is impossible ...

No, rather the opposite - it seems you need to get all the interaction with the database into separate threads - and the Active Object pattern is a good recipe for doing that, even if it might be an overkill.

When you want to update the ui, do it in batches - perhaps using BeginInvoke to pass something like 5000 records at the time to the ui thread.

Espen Harlinn 13-Jun-13 6:16am View

Have you heard of the Active Object pattern?
http://www.codeproject.com/Articles/56617/Applied-Long-Running-Active-Object-Pattern
http://www.cs.wustl.edu/~schmidt/PDF/Act-Obj.pdf
IMO you are trying to make this simpler than your requirements allows for.

Espen Harlinn 13-Jun-13 5:31am View

Create a separate connecton to the sql server for each thread, like:

[ThreadStatic]
private static SqlConnection connection;
void myWorker(object threadArgument)
{
connection = new SqlConnection();
using(connection)
{
connection.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
connection.Open();
// Now, do your stuff
}
}

public static SqlConnection Connection
{
get
{
return connection;
}
}

That seems to imply that you are using the samme SqlConnection on two threads at the same time, which should cause trouble for your program. You write that you only want the newest records and queues are usually a good solution for that

gibberish? I'm just telling you that the physical measurements is available through the EDID Basic display parameters, which is provided by most modern monitors - and that Windows retrieves this information. You can use an inf file to override the info provided by EDID, but that's rather unusual these days.

>> So I still don't get your problem with my answer
Not a problem really, you wrote: "I'm afraid I don't think it's necessarily that easy" - It is easy, OP is having a bit of trouble because he tries to do his own mapping instead of using the functions provided by Windows for that purpose.

I just thought you would be interested, that's all ...

Espen Harlinn 27-May-13 18:51pm View

1) In my experience Windows usually gets this right. "as whatever driver you have used for it" Certainly, it's not magic, and the info is provided through a driver ...

Windows managed to identify the correct display because modern displays do provide a bit of information, including maximum horizontal and vertical image size in centimeters, have a look at: http://en.wikipedia.org/wiki/Extended_display_identification_data

You can also download a nice tool from MS,EDID 1.3 and DDC Test: http://msdn.microsoft.com/en-us/library/windows/hardware/jj124739.aspx

2)I've not specified whether OP should use imperial or metric You didn't, OP managed that himself, take a look at his source code, near the top ...

I'm afraid you're wrong - Windows identifies my screen as Dell 3007WFP.

OP has called dc.SetMapMode(MM_LOMETRIC); so to get things right he needs to forget about inches and concentrate on 0.1 mm, which is what he has specified.

Yes, the typelibrary/activex constrol may actually not be registered on the target system.

Regsvr32, http://technet.microsoft.com/en-us/library/bb490985.aspx, can sometimes be used to fix this, but you need to have the access rights required to register the typelibrary/activex constrol on the target system.
