Symbian DMA

Currently I am spending a little ammount of time working on game development for the Nokia Series 60 phones. The problem I find is that after about 10-15 page flips (double buffered) the phone crashes. Is there a DMA interrupt that I need to hook up to? Do I need to limit the frames? If so, what to?

Any ideas welcome.

I am trying to write a program that will give me some basic info about my pocket pc device. I was wondering if anyone knows an API call that will tell me if there is an integrated biometric fingerprint reader on the device. I am writing this for a 2003 platform. Any help is appreciated.

Hello, i have a mobile web application and when i test it locally on my machine, the emulator is able to show the contents. However, when i try to test it with an online emulator or an actual phone, it says "could not reach the indicated web server".

I enter something like this on my phone :

"http://220.255.13.144/MyWapApp/MobileWebForm.aspx"

Anyone have any ideas?

can someone please help me here ? :/

im making a small pocket pc app with vs.net 2003 / c#

i need to add a small database to it ,
my first thought was pocket access , i made a small access file and transfered it ,
to my supprize there was no support for this in .net , or am i wrong?? is there some db provider for that ?

my next thought was to make a little sql ce db ...
that seems the way to go , but is there ANY easy way to design the db and then publish the db on lots of pocket pc's?

how do i get the db into the pocket pc w/o creating it by hand on the pocket pc itself???

hello,Reading a text file of integers with this code
for (k=0;k<256; k++)
{
for (l=0;l<12; l++)
fscanf(fmel,"%d",&melCdb->vq[k][l]);
for(l=0;l<12;l++)
{
fscanf(fmel,"%d",&aux);
// melCdb->cov[k][l]=2*aux;
}
}
the program breaks when k=16 without any reason in
fscanf(fmel,"%d",&melCdb->vq[k][l]);
there is more than 10mb of free memory in the Pocket PC and this code works properly with the same file in in the desktop with VC++ 6.0.
Somebody knows what is the problem?
Thanks

Try this:

...
for (l=0;l<12; l++)
{
int value;
fscanf(fmel,"%d",&value);
melCdb->vq[k][l] = value;
...

If this doesn't help:
How do you create the array melCdb->vq[k][l]?
Please show us your source code!

Hello, the source code is
melCdb->vq=(long **)malloc((256)*sizeof(long *));

for (k=0;k<256; k++)
{
melCdb->vq[k]=(long *)malloc((12)*sizeof(long));
}

for (k=0;k<256; k++)
{
for (l=0;l<12; l++)
fscanf(fmel,"%d",&melCdb->vq[k][l]);

for(l=0;l<12;l++)
{
fscanf(fmel,"%d",&aux);
}
}
I have already checked that mallocs give dinamic memory correctly.
Thanks for your help.

Try this:

for (k=0;k<256;k++)
{
for (l=0;l<12;l++)
{
  long* pl = melCdb->vq[k];
  fscanf(fmel,"%ld",&pl[l]);
}
}

Don't forget to use %ld in the fscanf function, because this are the right syntax for a long.

Uploading data to emulator?

Do you know how data files can be uploaded to the PocketPC and Windows CE .NET?

Is it possible to create an ethernet connection between the host PC and the Windows CE emulator (or simply to create lan)?

Any information about using these emulator is appreciated. Thank you!

You can map a drive to a network share on the host PC from within the emulator; just open File Explorer on the emulated device and map it from there.

Embedded VC++ emulation hangs

Hello!

I'm new to PocketPC development so this question might have been asked by someone else Smile | :)

.

I use Microsoft Embedded VC++ for development. When i have created a project and wants to build it, i can only build it directly to my PocketPC. Whenever i choose "PocketPC 2002 Emulation", my computer bluescreens and reboots. There is not enough time before the reboot for reading the bluescreen content.

Any ideas?

Try getting more RAM. At 512 MB, the emulator never crashed on my laptop (Win 2K). Also, you can try reinstalling the 2002 SDK. If everything fails (a very decent probability), consider buying a real device. I did that...

Thanks! I've got a real device. I just thought that it would be quicker to emulate than to develop on the "real thing". Programs created and downloaded to the PocketPC i've got works just fine Smile | :)

Again, thank you!

Dear Friends,

Does anybody know how to set break point on a shared
memory location using Embedded VC++ 4.0 debugger.

I have a dll[C language] that allocates and uses shared
memory. I want to set break point on some memory locations
of allocated shared memory.

When set memory break point in debugger currently it is
not functioning. Execution stops there and i can not
proceed further except closing Debugger.

Thanks in advance,

Dear Friends,

Does anybody know how to get child Window Rect coordinates wrt to parent window Rect coordinates. [Something similar to GetRectInContainer()]. I want in SDK rather than in MFC.

Thanks in advance,
subramjobmail.

Do you mean you want the position of your client window inside the parent window?

RECT rtClient;
// Get the position of the client in screen coordinates
GetWindowRect(hClientWnd, &rtClient);
// Converts the screen coordinates to client coordinates
ScreenToClient(hClientWnd, (LPPOINT) &rtClient.left);
ScreenToClient(hClientWnd, (LPPOINT) &rtClient.right);
