I have realised what is the root of my problem: I am somehow unable to override my clistensocket::onaccept function. I have tried the solution u have posted and my own method of transfering the clistensocket::onaccept function to the main dialog classes but still I am unable to override my function. So, can any experts point why did I go wrong?

Memory Leaks in SqlCe

Hi all,

I am currently developing a PocketPC application using SqlCe2.0 and Evc++ 3.0. I am using SSCEOLEDB.

I saw the following thread in google

http://groups.google.co.in/groups?q=memory+leaks+in++ssceoledb&hl=en&lr=&ie=UTF-8&selm=078301c33c6c%24de966a80%24a301280a%40phx.gbl&rnum=1

regarding the memory leaks in SqlCe2.0 and EVC++ 3.0.

I am into the same problem now.

Memory leaks occurs every time i execute ICommandText->Execute() method.

I heard that memory leak occurs due to ICommandText->Execute() when we use Oledb for oracle. Does the same problem occurs in SqlCe2.0?

Kindly send your suggestions.

Owner Drawn ListBox in CE???

Greetings to all,

I am in need of some sample code or documentation (something, ANYTHING) to get me started. I've just been thrown into the CE development arena and need to write an Owner Drawn ListBox Control that will run under CE. It needs to display different fonts, fontcolor, and background colors on a line by line basis. I've not worked with CE and need a place to start. Any suggestions would be appreciated.

No freakin' way... Wink | ;)

(no OS support)

Use the list view control instead: Cool | :cool:

one column and a custom draw bonanza to fill in your wildest dreams (and there are lots of articles here on CP too).

But if you really really really must use a list box, try these general principles (good luck - it's not easy Eek! | :eek:

):

QA: How do I create a combo box with check marks?[^]

seeking mp3 component for pocket pc

mad_sci14-Jul-04 4:09

14-Jul-04 4:09

i am developing a freeware app for pocket pc and am seeking an mp3
player component that from code, i can make play, pause, jump to a specific
time in the track, and read the elapsed time (pref in seconds) and
total track time. something that lets you control the play bar or view the
file graphically (waveform) as it plays and click on a portion to jump
play to that part would be nice but not necessary.

currently the only thing i've found is this cfcom product by odyssey
that lets you embed windows media player, but it's way too expensive and
has too limited license for the $ (i would pay for such a component as long as it was affordable but $400 ain't!)

does anyone know about anything that might work? someone at opencfnet.org found a way to p-invoke WMP, but you can't read the elapsed time or tell the player to jump forward to a specific time so that won't do for my purposes.

i am working in vb.net for compact framework, so either a .NET
assembly that i could include in my project, or vb.net or c# code would be
best c++ would be way over my head.

any information or advice would be most appreciated!

Question about cab files and inf files

Cedric Moonen13-Jul-04 1:48

Cedric Moonen

13-Jul-04 1:48

Hello !!
I have a question about making the cab file with cabWizzard (using an inf file).

I need to install a complete application on the pocket PC. This application supports multiple language. I have a resource directory in wich there is a sub-directory for each language. In each of these subdirectories, there are files containing the string in a specified language. So, the files from the different sub-directories have the SAME names.

For example:
....\MEC\NLS\FR -> contains the file PDI.str with the strings in french
....\MEC\NLS\ENG -> contains the file PDI.str with the strings in english

So now in my inf file (in order to construct the cab file), how do I specify that for the french resources, I need the PDI.str in the FR directory and for the english resources, I need the PDI.str in the ENG directory.

I wrote something like that:

[DefaultInstall]<br />
CopyFiles = BinaryFiles, FrenchResources, DutchResources<br />
<br />
[SourceDisksNames]<br />
1 = ,"Common files",,C:\MEC\Sources Pocket\Pocket Download\BIN<br />
2 = ,"French resources",,C:\MEC\Sources Pocket\Pocket Download\NLS\FR<br />
3 = ,"Dutch resources",,C:\MEC\Sources Pocket\Pocket Download\NLS\NEE<br />
<br />
<br />
[SourceDisksFiles]<br />
PDI Lite.exe = 1<br />
PDI.str = 2<br />
PDI.str = 3<br />
<br />
<br />
[DestinationDirs]<br />
BinaryFiles = 0, %InstallDir%\BIN<br />
FrenchResources = 0, %InstallDir%\NLS\FR <br />
DutchResources = 0, %InstallDir%\NLS\NEE<br />
<br />
<br />
[BinaryFiles]<br />
"PDI Lite.exe"<br />
<br />
[FrenchResources]<br />
"PDI.str"<br />
<br />
[DutchResources]<br />
"PDI.str"<br />

...And magically, that does work Confused | :confused:

but I don't know why ? How can the cabwizzard differenciate the two PDI.str in SourceDisksFiles entry ???

Another little question: how can I copy dll's and register them automatically (with specifying something in the .inf file) ?

Thanks for your responses Smile | :)

Ooops... No sorry, in fact that doesn't work Wink | ;-)

.

In this case, for the French and Dutch resources, the same file will be copied, that is the file in Dutch (the last one in the SourceDisksFiles entry).

How can I specify that in the %InstallDir%\NLS\FR I want the file that comes from the ....\MEC\NLS\FR directory on the desktop PC and that in the %InstallDir%\NLS\NEE directory I want the file from the ....\MEC\NLS\NEE directory ???

Thanks

storing blob data in sql ce

12-Jul-04 3:52

Hi All,

I am trying to store the large objects into SqlCe database. I have the datatype as image in the sql ce. The data to be stored is available as BYTES. Could anyone suggest me some solutions to achieve the same.
I tried to save by executing the commandtext. But i was not able to build a query using the byte data. I tried to use the IRowsetChange interface wherein i retrieve a rowset and update the same using the IRowsetChange->SetData(...) method. I was not able to store the data still and the program doesnt execute beyond the setdata method.

Any suggestion in this regard will be helpful.

Development environment:
EVC3.0
SqlCe.

rmkmani.

A serious bug of list view in compact framework

Hi~

Lei wrote
"I have 2 forms, form1 contains a ListView. What I want to do is, when
clicking an item in the ListView, hide form1 and show form2. Code for
ListView's SelectedIndexChanged: { form2.Show(); this.Hide(); }. When I
click the item, form2 shows with form1's title and menu. I noticed that when mouse down, the SelectedIndexChanged event was triggered and bring form2 to front. But when mouse up, system redrawed the selected item and bring title and menu back to form1's. I tried to handle MouseDown and MouseUp event of ListView but they were never triggered. Now I used a tricky way to solve the problem: start a thread and use Control.Invoke to switch forms. It is not good, I think there must be a better solution. Thanks."

I am facing the same problem. Someone solve it with setting timer. However, is there any other way to solve it?
Thanks~
