XML over GPRS - Is this a good idea?????
Hi All
I was hoping some one could give me some guidance on the matter of sending
data over GPRS.
I have taken over an application written for Windows mobile 5.0 with VS2005.
It is currently communicating with a web service via GPRS.
The Web service places all the data into objects and then returns it to the
PDA. And the same happens when sending stuff to the Web service from the
PDA.
My concern is the amount of Meta data(xml) that is being sent just to
describe the Data itself.
Is there a better way of doing this? Or do I have to live with it if I want
to use OOP.
Thanks

optimizing for JIT and generics, possible bug/issue?
We've noticed in our project that adding a reference to a new
Dictionary<> type adds about 600ms to the JIT time of a class.
For example, class A has a private member variable: private
Dictionary<string,CustomClass> _var;
When assembly.CreateInstance() is called for class A, it is 600ms
slower WITH the reference to Dictionary than without.
Is this a known issue, and are there any better workarounds than making
my own typed dictionary class? Tag: BUG? How send params in WebMethod from PocketPC? Tag: 77299
does a toolBarButton with pushButton style not popup contextMenu??
Hi,
I need to have a menuBar with some images, which when selected
should popup a menu. But the toolBar does'nt provide the exact thing
what i require. It does'nt popup the menu when the button style is
pushButton. It works only with dropdown style. But this style also
displays the dropdown arrow. Is there a way that i could let the menu
popup for pushButton style button?

application to my client so that he can have a look at code. I have to
write a document to instruct him to how run this application on

Throws:-
{System.Net.Sockets.SocketException: The system detected an invalid pointer
address in attempting to use a pointer argument in a call
at System.Net.Dns.ResolveInternal()

The SocketException contains an ErrorCode (0x0000271e) that equates to the
following socket error:-
The system detected an invalid pointer address in attempting to use a
pointer argument of a call. This error occurs if an application passes an
invalid pointer value, or if the length of the buffer is too small. For
instance, if the length of an argument, which is a sockaddr structure, is
smaller than the sizeof(sockaddr).

Howto fill a sql mobile database with a dataset filled with readxml
Hi All,
On the desktop I have multiple SQL server 2005 Express edition tables.
On the server, I use a dataset in combination with writexml to generate an
xml file (dnldata.xml) from a couple of queries
(DnlData.WriteXml("c:\test\Dnldata.xml"))
After it, I transfer dnldata.xml to the pda and use ReadXml to fill a
DataSet.
What is the easiest (best) way to read the dnldata.xml into an SQL MOBILE
2005 database (*.sdf)?
The old fashioned way was using csv files with records, mannually inserted
into the pda database. I want to change that.
The structure of the SQL server 2005 Express edition tables and the SQL
MOBILE 2005 tables on the pda
are exactly the same.
Do I have to parse all the records manually?
Or Can I use Dataset.readxml in combination with other data-objects?
probably this is not the right way.
Any help would be greatly appreciated.
best regards
I tried the following which not seems to work:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Dim DnlData As New System.Data.DataSet
Using MySqlConnection As New
System.Data.SqlServerCe.SqlCeConnection( _
"Data source=" & "\Storage Card\Ztest\Mydb.sdf" & "; " & _
"SSCE:Database Password=xxx; " & _
"SSCE:Encrypt Database=True")
Using MySqlCeDataAdapter As New
System.Data.SqlServerCe.SqlCeDataAdapter("Select * from klant",
MySqlConnection)
Dim MySqlCeCommandBuilder As New
System.Data.SqlServerCe.SqlCeCommandBuilder(MySqlCeDataAdapter)
MySqlConnection.Open()
DnlData.ReadXml("\Storage Card\Ztest\Dnldata.xml")
MySqlCeDataAdapter.InsertCommand = MySqlCeCommandBuilder.GetInsertCommand
MySqlCeDataAdapter.UpdateCommand =
MySqlCeCommandBuilder.GetUpdateCommand
MySqlCeDataAdapter.DeleteCommand =
MySqlCeCommandBuilder.GetDeleteCommand
' MySqlCeDataAdapter.Update(DnlData)
'

PPC Synchronization
I need to sync my pocket pc to a server. I'm thinking of using
"funambol." Has anyone tried using it?
And one more thing, if I'm going to synchronize PPC to a server, may it
be through funambol or active sync, will my keys and ID's change in the
server? And if ever it would change, how would I get or retrieve the
mappings of the ID's of items (such as tasks, calendars,account,
etc...)? I need it to make the my PPC application consistent and
working in the server.

Exporting images to XML
I'm writing an application that holds a signature image in a SQLCE
database. I need to export this image to an XML file. I have tried this (in
C#) with DataSet.WriteXML(filename) and it works fine; the resulting image
seems to be compressed (a little under half the original size) and is
human-readable (no weird unprintable characters). However, I am parsing all
the records and exporting only the fields I need.
I have two questions:
1) Is there a way to tell WriteXML() which fields I want to export?
2) How can I compress/write the image data the same way as WriteXML()?
Thanks,

byte[] wavFile =

byte[] byte1 = encoding.GetBytes(postData);
// Set the content type of the data being posted.

z-order with DX and CF
Hi,
I have the following problem with DirectX (CF) that I'm still trying to
figure out...
The thing is that I need to draw a lot of (dynamic) sprites, but I was
used to (in other languages) the fact that the latter sprites you draw
are placed in front of the others.. This is not the case of DXCF, since
(I'm guessing for optimization reasons) the order in which you draw the
sprites is not related to the order in which they will appear in the
screen...
So, is there someway to change the z-index ?(meaning the index of a
sprite in the z-buffer)...any thoughts/walkarounds?? Or maybe a way of
forcing that the order you draw the sprites is the same that the order
they will appear?? (even if this implies a performance drop down)
Thanks you very much in advance.

Help?
I've posted something very similar to this in the SQLServer CE area but but
just am not getting any response over there so I figured I'd tap the brain
trust over here!
Recently ported my VB.NET PPC app to VS2005. Also replaced my database (SQL
Server 2000) with the SQL Server 2005. I knew I'd probably have to install
a new server agent for the SQLserver2005 database to still be able to RDA
Pull from it.
Welp I tried and did not succeed in pulling using the new syntax (really I
just changed the agent dll name that was in the newly created IIS virtual
directory SSCE30.) Did any of the calling code change?
With rda
.InternetLogin = String.Empty
.InternetPassword = String.Empty
.InternetUrl = _strInternetURL
.LocalConnectionString = g_strlocalDataSource
.Pull("Users", strSQL, _strRemoteConnect,
System.Data.SqlServerCe.RdaTrackOption.TrackingOff)
End With
Anyway I went back to the old SSCE20 pointer and THAT actually works with
the new SQLServer 2005 database!!
Weird eh?
My general question is this: Apparently in debug run mode via ActiveSync,
it IS possible to use the old agent DLL sscesa20.dll to Pull data from a
SQLServer 2005 database. I've not been able to do this from the ethernet
cradled device running the same code. If my app might be paired with either
Windows 2000 SP3 OR SQLServer 2005, must I right different code to branch to
the appropriate agent? or is there an agent that I should use that is
compatible backwardly?
TIA

Emulator Shared Folder problem
Hi,
I'm using the PPC 2003 emulator with C#2005, Sql Mobile 2005 to test my
application. I have a storage card emulated which is part of my c:\ drive
and has a sql ce database on it.
When I try to insert records, the record is inserted (Affected records : 1)
and removed right away. No errormessage is returned. Everything works fine
when I move the database to the emulator instead of the storage card.
Does anybody know why this happens ? I found someone that has the same
problem, so I'm sure it has something to do with the shared folder on the
emulator, but no solution or explanation.

The functions do some basic rawread and rawwrite on an SD card.
Now how can i use this code in the c# (managed code). Specifically i
need to know how to marshal "char *".
I did try out with the following code (the dll created by evc++ was
SD_card_dll.dll. But it doesnt seam to work.
[DllImport("SD_card_dll.dll")]
public static extern void OnRawRead(int memory_location,ref
IntPtr lpOutBuf);
[DllImport("SD_card_dll.dll")]
public static extern void OnRawWrite(int memory_location,ref
IntPtr lpBuffer);

Selecting a particular .NET framework version
Hi,
I just started developing applications on the .Net Compact Framework.
I've got .NET 1.1 and 2.0 installed on my machine along with VS 2005.
However, each time I deploy, it deploys it as a .NET 2.0 application.
How can I programmatically check and change the version of the framework
to use on the device. Basically I want to use v1.1. Any help would be
appreciated.
Thanks,

determine if pocket pc 2003 device has been disconnected from the network
I currently have an app running on a pocket pc 2003 that connects to a
webservice to update information. The device is using gprs for
interconnectivity. In one particular module, data is sent to the server and
waits on a feedback from the server. However, sometimes the gprs service is
dropped and then the device hangs waiting on a response. The update is done
in a try catch block but the device apparently gets no error indicating that
the signal has been lost.
How can I prevent the device from freezing when the signal is dropped? Is
there a timeout setting I can set within my code that I can check to see if
a response has failed to come in within that time? If so, how do I do this?
I am using vb.net 2003.

C# IntPtr with moved memory location, how to apply 'fixed'?
Hi,
i have an unmanaged C dll and i call a function from C#
which returns a pointer on a struct inside the C dll:
// C# code:
//member variable
IntPtr intPtr;
someMethod() {
intPtr = getStruct(); // calls C dll
}
when i later use the intPtr (passing it to C dll) it seems to point to another
memory location.
I have tried something like
fixed (void *p = intPtr.ToPointer()) {
...
}
but this does not compile:
"You cannot use the fixed statement to take the address of an already fixed expression"
How can i fix my memory location?
Thanks

RDA Pull SQL Server versions
I've posted something very similar to this in the SQLServer CE area but but
just am not getting any response over there so I figured I'd tap the brain
trust over here!
Recently ported my VB.NET PPC app to VS2005. Also replaced my database (SQL
Server 2000) with the SQL Server 2005. I knew I'd probably have to install
a new server agent for the SQLserver2005 database to still be able to RDA
Pull from it.
Welp I tried and did not succeed in pulling using the new syntax (really I
just changed the agent dll name that was in the newly created IIS virtual
directory SSCE30.) Did any of the calling code change?
With rda
.InternetLogin = String.Empty
.InternetPassword = String.Empty
.InternetUrl = _strInternetURL
.LocalConnectionString = g_strlocalDataSource
.Pull("Users", strSQL, _strRemoteConnect,
System.Data.SqlServerCe.RdaTrackOption.TrackingOff)
End With
Anyway I went back to the old SSCE20 pointer and THAT actually works with
the new SQLServer 2005 database!!
Weird eh?
My general question is this: Apparently in debug run mode via ActiveSync,
it IS possible to use the old agent DLL sscesa20.dll to Pull data from a
SQLServer 2005 database. I've not been able to do this from the ethernet
cradled device running the same code. If my app might be paired with either
Windows 2000 SP3 OR SQLServer 2005, must I right different code to branch to
the appropriate agent? or is there an agent that I should use that is
compatible backwardly?
TIA

File.Copy() crashes with very large files
When I try to copy a very large file (>8mb) using File.Copy() I get the
following error (may contain spelling errors, I typed it over):
=============================
OutOfMemoryException
IOException
at System.IO.__Errot.WinIOError()
at System.IO.File.InternalCopy()
=============================
How can I prevent those exceptions? What is sane to do? First check the
file size before copying? But what would be the maximum possible size?

Prevent light-off/key-lock/suspend/standby
My application has to upload quite some data, which takes a long time.
In the meantime the device goes into 'suspend' mode (at least the light
turns off and the keypad gets locked). The side-effect is that the
network connection is broken as well (at least the WiFi connection).
How to prevent 'suspend' can be found here:
http://msdn2.microsoft.com/en-us/library/z4k4wb9k(VS.80).aspx
But that didn't solve my problem. How can I prevent the screen from
going black and the keys from becoming locked? Tag: BUG? How send params in WebMethod from PocketPC? Tag: 77176
KeyPreview?
Hi,
We are developing a WinCE app for PocketPC 2003 (.net 2).
I am using KeyPreview = True in my forms to be able catch some keys and do
special processing in the forms (like shortcuts).
We have a main menu form that uses those shortcuts to call other forms. If
we have keypreview = true in the children forms when they are activated the
KeyUp event is called in the form (like the key was pressed for them, ie:
like pressing the key twice).
Any ideas?
