Work with SQLServer 2000 CE
Hi, I have to work with a SQLServer 2000 database. How I migrate the
database with all data to the iPAQ? I have installed sqlserver CE and i can
create a database with SQLCE Query but i don't know the way to use my
sqlserver database.
Help please!! Tag: file version Tag: 9604
KeyDown ignored by several important controls
I have a recursive function that snakes throughout a form and all of it's
sub-controls to set a KeyDown event (to listen for the 'ESC' key). However,
several important controls, like the combobox and even buttons do not seem
to properly listen for keydown events. Is this by design? If I want to
enable a given hardware key throughout a form, is there a better way to
achieve this?

Disable Power-On Notifications?
I have a full-screen application that locks the taskbar (kind of like a
kiosk app); however, upon a power off/on toggle, sometimes the taskbar
appears, and being that it's locked, it covers the top of the screen until
it is forced into the foreground. Is there any way to prevent the taskbar
from receiving notifications on power up or otherwise keep the taskbar
constantly hidden?
We even capture the IntPtr to the taskbar window handle, then re-enable the
taskbar, then kill focus on the taskbar, then set focus on the current
full-screen form, then re-disable the taskbar, but that doesn't work. Any
ideas?

Webrequest.GetResponse error - no end of entity mark
Here is some Visual Basic code I'm using to submit a HTTP GET to an URL
that should be returning some plain text data (MIME type is "text/Plain").
When I run the code on the PocketPC emulator, I'm getting the error "The
response did not contain an end of entity mark" in the
Webrequest.Getresponse method.
Any idea what the error means? I can find zero documentation. I only get
the error in the Pocket PC version of my application (the same code works
fine in Windows!), and only when submitting to this particular URL (the URL
is for a built-in webserver for a piece of network-enabled audio hardware).
Dim sResponse, rspText
Dim req As HttpWebRequest
Dim rsp As WebResponse
Dim rspStream As Stream
Dim creds As New NetworkCredential(userID, password)
Dim sURL As New Uri("http://192.168.0.103/apicmd.asp?cmd=next")

Web Reference "URL Behavior"
I have a .NET application for PocketPC that uses a Web Reference. I need to
be able to dynamically change the URL of this web reference and have read
about the "URL Behavior" property of the Web Reference and changing it to
Dynamic, but I don't have this property for some reason. Is it because it
is a PocketPC application? How else can I change the URL dynamically? Tag: file version Tag: 9583

Webrequest.GetResponse error - no end of entity mark
Anybody know what could cause the error "The response did not contain an
end of entity mark" in the Webrequest.Getresponse method?
Here's some background: I'm writing a Pocket PC app in Visual Basic
that communicates with the Turtle Beach Audiotron, a hardware digital
music server that can be controlled over the network via a built-in web
server. Turtle Beach published a programming API for the Audiotron;
commands are sent as HTTP GET requests. E.g., you tell the audiotron to
advance to the next track by sending the URL
"http://192.168.0.103/apicmd.asp?cmd=next", where 192.168.0.103 is the
network address of the audiotron. The Audiotron API also states that
replies from the GET are returned as plain text data (MIME type is
"text/Plain"). In the case of a successful "next track" command as
described above, the response would be "Error 0 - Success/n".
Ok, so here's my code that sends a "skip to the next track" command to
the audiotron. It works fine in my PC-based version of the app, but
the GetResponse method gives the aforementioned "The response did not
contain an end of entity mark" error when executed in the .NET compact
framework and deployed to the PocketPC emulator.
Dim sResponse, rspText
Dim req As HttpWebRequest
Dim rsp As WebResponse
Dim rspStream As Stream
Dim creds As New NetworkCredential(userID, password)
Dim sURL As New Uri("http://192.168.0.103/apicmd.asp?cmd=next")
req = WebRequest.Create(sURL)
req.Credentials = creds
req.Method = "GET"
rsp = req.GetResponse()
rspStream = rsp.GetResponseStream
Dim readStream As New StreamReader(rspStream, Encoding.UTF8)
rspText = readStream.ReadToEnd()
rsp.Close()
I can't find any documentation for the error (usenet searches, MSDN,
websearches, etc.). I have confirmed that it is not an emulator
communication problem, as the code works for external URLs (such as
www.google.com) and for another webserver inside my network (my
router's built-in webserver). Also, If I put in an invalid URL, I get
a completely different error. So the error is received only when
communicating with the Audiotron's built-in webserver, and even then
only in the .NET CF. I would love to hear any ideas!
Thanks :) Tag: file version Tag: 9572
Is Control.Invoke supported?
Hi,
The Visual Studio .NET 2003 documentation says that .NET Compact Framework -
Windows CE .NET supports Control.Invoke (i.e. accessing windows forms
controls from a thread they were not created on).
I'm trying to use Control.Invoke on a Pocket PC 2002 device and I get an
"Argument Exception" managed error.
Has anyone been successful with Control.Invoke and if so do you have some
sample code? My code works on the desktop but not on the Pocket PC.

Help in API
We're trying to do a few things here without success and I would like to ask
for your help, please.
1) Disable and re-enable auto suspend
have found that we could P/Invoke
SystemParametersInfo(SPI_SETBATTERYIDLETIMEOUT, 0, NULL, TRUE) but haven't
found any working example and have no idea on how to start
2) Get free disk space
we could P/Invoke GetDiskFreeSpaceEx but no working example either
3) Get free memory
P/Invoke GlobalMemoryStatus, no working example either
4) Get remaining battery
- P/Invoke GetSystemPowerStatusEx - have found an example but couldn't get
it to work
- could use OpenNetCF.BatteryStatus but I still don't want to go that way...
I'd rather P/Invoke it myself...

print from a pocket pc
Can anybody tell me which is the best solution to print something with a
program written in vb.net for a pocket pc?
I'm a bit confused on the whole process, so I'll try to explain what I need.
I'm going to write a Smart Device Application (using Visual Studio 2003 and
VB.NET code) for a pocket pc: one of the features to provide with this
application is the print of a final report (doesn't matter if html, word or
pdf) made of only text, connecting to a small mobile printer.
I've a pocket Pc supporting bluetooth (Compaq Ipaq 3900), but not yet a
mobile printer: the idea is to buy an hp printer (something else to
suggest?), connect the two via bluetooth, and add to application the code to
print he page, using hp mobile printing sdk.
I hope you'll suggest me examples, technical articles or useful links: any
help would be apreciated.

WebService and CF Performance - Again the issue
Hi, I've replied to a thread about this issue but it was rather old so i'm
posting a new one...
I'm having very poor performance acessing webservices!
I'm using both SQL CE Replication and WebServices to send data to my Pocket
PC from the cradle or GPRS.
Replication works fine, but webservices take several seconds to execute, up
to 20 or 30, which is unacceptable.Thing is I want to keep webservices...
I'd be very interested in earing from microsoft, or anyone else, about this
one.

REe Creating a setup File for CF Application
Maybe not technicly this group, but this was where the original posting
was...
I'm using EzSetup, but each time I run it using the commandline:
ezsetup -l english -i MyApp_PPC.ini -o MyAppSetup.exe
in a command window, all I get back is the syntax text, not even an
error. All cabs and the ini file are in the same directory as ezsetup.
I was wondering if all options have to be supplied (in my case, no eula
or readme).
Contents of my ini file is as follows:
[CEAppManager]
Version = 1.0
Component = MyApp
[MyApp]
Description = "My new App"
;Because there are multiple .cab files specific to a CPU type,
;these files are relative to the installation directory.
CabFiles= MyApp_PPC.ARM.CAB; MyApp_PPC.ARMV4.CAB; MyApp_PPC.MIPS.CAB;
MyApp_PPC.SH3.CAB; MyApp_PPC.WCE420X86.CAB; MyApp_PPC.X86.CAB
This format was pilfered off of another posting, but without the listing
of multiple cabs. I also tried using commas to separate the file names,
but with no luck.
Any help would be greatly apprieciated.

IrDA DiscoverDevices
Using VS NET 2003 C#
O2 XDA (Pocket PC 2002)
Nokia 6150 (6100)
The InfaRed Function of Pocket PC can find the Nokia 6150 Mobile Telefon.
When I run a program with :
IrDAClient irdaClient = new IrDAClient();
IrDADeviceInfo[] irdaDevices;
irdaDevices = irdaClient.DiscoverDevices(10);
irdaDevices.Length is allways 0. (No Exceptions)
If the PDA can find the Nokia then why can't IrDAClient find it?
Has any body tried this on a O2 XDA with different results?
For that matter has anybody had the same results, but has found it to be
Machine specific ?
I have tried a c++ Sample (IrdaMobil) that looks for a Nokia 5300 with a AT
Command. Connection to (IrDA Port) COM2 and COM3 works but the AT Commands
recieves a Timeout.
So the main questions are :
- is it the O2 XDA Maschine ?
- or am I doing something wrong ?

How to "free / dispose" objects?
Hi,
i'm really new to .NET and i know, that the garbage-collection should free
objects itself... but is there any way to force this?
for example: i have a loop in which i need to create a new object every
time, fill in some data, store it to a database and then... free it...
[pseudo-code]
while (readline(myLine) != eof)
{
TMyObj tempObject = new TMyObj;
tempObject.abc = "abc";
//...more data to fill
StoreObject(tempObject)
//in pascal i would do:
// tempObject.Free;
}
[/pseudo-code]
The loop will run thru about 100000 times - so 100000 objects are created
but only used for a very short time!
I need a new object to have a new reference - so a Clear-Function to clear
my data is not enough.
Question: WHEN will the garbage-collection free the instances of the loops
before?

Keydown Event losing focus
Hi,
I'm using the Keydown event on a form with a panel and scroll bar on
it, to trap the user pressing the hardware scroll buttons. It works
fine when the form is first loaded, however if the use selects a
control, then the scroll bar doesn't work on the form any more. Is
there a way of ensuring that the form always has focus so if the
scroll bars are pressed, the keydown event is fired as when the form
first loads?
