hi lucky...
that would be a perfect solution, but in response to what message?

I think you could refresh all the window by handling the ON_SCROLL message or something like that

Hello,
I am trying to repaint just a small rect of my dialog.. The dialog has a Bitmap background and I have a static text (timer) that gets updated every second.. The problem is when it updated the static text it doesnt repaint the background so I get a bunch of numbers placed over the top of one another.. Looks really bad.. I can do a RedrawWindow() and it will repaint correctly but it repaints the whold dialog box (causes flickering) looks very anoying.. Im trying to just repaint a rect but I need the rect to be repainted just as well as if I were to do a RedrawWindow() on the whole dialog box.. this is what I have tried.
CRgn rgn;
rgn.CreateRectRgn(17,44,29,13);
CRect rect(17,44,29,13);
RedrawWindow(&rect, &rgn, RDW_INVALIDATE | RDW_ERASENOW | RDW_UPDATENOW);
I have tried several different flags but none of this seems to do the same thing as plain old RedrawWindow();
Any Ideas?

If you provide a region pointer, the rect pointer is ignored. Have you tried RDW_ERASE instead of RDW_ERASENOW, which would give you the defaults exactly as if you'd just done RedrawWindow(); ?

I changed the rect pointer to a null and used the RDW_ERASE with the RDW_INVALIDATE and it still doesn't redraw like RedrawWindow with out any params.. strange.
Not sure what this isn't working.

For my next project, I'd like to be able to see how many keys I've typed over the years and be able to compare this measure of geekiness with others. I don't necessarily need to know what is typed (though that would help any stats ideas in the future). Can anybody point me in the right direction for learning the ropes with global hooks and keytraps in Win32? I'll probably have followup questions for you too...
Thanks...
(BTW, this is sort of like the old uptimes.org, but on a different slant  )

Hi,
I am trying to develop an administration client (GNU) for mysql and I am looking to develop an interface similar to mssql 2000. I am going to want to have dynamic content in the pages so static html files won't work. Does anyone have any suggestions how to approch it. I have tried http://www.codeguru.com/ieprogram/HtmlMemory.html except this causes problems when you deal with a large amount of HTML you flood out the LPSTR variable. Is there a better tutorial out there regarding this?
Is there a better way to apporch this, or do you think I am doing something wrong?

You may want to consider hosting the MSHTML component yourself and use the IPersistStreamInit Interface together with a memory stream.
Since this is a stream, it does not have the cap like the string version. I can't remember exactly but I think the cap is something like 1024 Kbytes?
Cheers

Hello,
Just for educational purposes I am trying to write an MP3 player.. I have implemented the stop, play and pause buttons plus volume control and a few other things.. I'm stuck on trying to figure out how I can display or determine the length of a song in seconds (I've looked through codeproject, codeguru and MSDN).. Anyone know a good place to start or does anyone have any samples of code on how to determine how long a song is and display it in a string?
Thanks,
Rob

Um... are you saying you've written a class that plays mp3's ? I don't suppose you're going to post it 
As to your question, you can use DirectShow to get the length of a media file, and then do what you want with it. You just load the file and render it, but you don't play it, you just query it for it's length. If you want more info, it's at home, just remind me. I did it for a program that catalogs media files.
Alternatively there is a program on CP that does MP3 playing and displays the length, it's listed as an example of a skinable app, I forget the name/details. I remember it because I tried to get the mp3 playing code out of it, but it was in C, and that meant I couldn't play 2 mp3's at once ( I'm keen to be able to use mp3's instead of wav's for in game sounds ).

Thanks Christian,
I think I know of the program.. I'll take a look at it. When I'm finished I could post some code.
Thanks again!

That would rule. Is it class based ? Because my problem with the other code was that it's all globals so I couldn't create two instances of the mp3 decoder and have them play different files at once.

It's not class based (yet).. I just started writing it yesterday morning.. I'll see how it turns out and I'll let ya know.

Why would you want to play two mp3 clips together?

One for each ear....
Actually, as I said, the idea was to play mp3's in game instead of waves. I've not done any game development for ages, but the idea is that I was working on a Direct Sound library, to simplify it all, and I'd like to be able to use mp3's because it allows my game to be smaller in size. It would also make it easy to add the ability to play your own music in game.

hey christian
don't you think decoding mp3's in a game is a waste of cycles? i don't know for sure what the % of processor time is reqd to decode mp3's but it seems significant from all the software i have to do it
just a thought

Very possibly, I was hoping to have a chance to try it and find out.
My game was not in 3D, so I had cycles to spare and a lot more space was devoted to wavs than to code or bitmaps, so in my case it was a good idea I thought.

Christian,
I don't know if you noticed, but Age of Empires II uses MP3 files for all their sound files. Ironic isn't it? And here they are pushing their own WMF format... I guess it's because it was actually Ensemble Studios that made the game. My point is that MP3s in games have been a reality for some years now.
I'm also somewhat interested in learning about the MP3 format in depth, so I can write my own utilities. Unfortunately I have to first find a way to stop playing AOE.
Regards,
Alvaro

No, I didn't notice that, although I have AOE II.

I know what you mean - I played it for a week and forced myself to stop so I could get some work done....

I used app wizard to build a dialog box to display the command line. The app wizard built two classes, test.cpp and testdlg.cpp. I added Carlos Antollini's command line class and using debug I can see the command line value in the test.cpp class(InitInstance) but can not figure how to get the value into the testdlg.cpp class. I have built an edit window and can use UpdateData() to put a value in to it.
Any help would be greatly appreciated.

It is not completely clear to me what you want to do. However, if all you want to do is display the command line arguments in a dialog, I would use a listbox. Add a listbox to the dialog using the resource editor. Using the class wizard, add a member variable of type CListBox to the dialog class and map it to the listbox control that was added. Then in the OnInitDialog function add this :
CYourDialog::OnInitDialog()
{
for( int i = 0; i (less than) __argc; i++ )
m_ListBox.AddString( __argv[i] );
}
That's it. This will fill the listbox with one argument per line.

I use SetFieldValue to add a record to database,
but each time only the first character was added to database.

You'll need to post your code. I've not seen this behaviour from SetFieldValue.
