Dear All,
I need to set/pass cursor type and lock type in OLEDB interface. I opened the table/SQL statement successfuly. I am not able to find in which interafce i have to pass/set cursor type and lock type in it.
Any body is having any idea about this problem ?
If so, provide some input and it will be of an immense help for me to solve this problem.
Regards,
AKS

Cursor and lock information are passed on the property set of type DBPROPSET_ROWSET. If you are using SQL CE, check out the online docs.

Hi there,
I've installed VS 2003 .Net, Pocket PC 2003 SDK and ActiveSync 3.7.1 on my PC.
I also intalled Microsoft Loopback Adapter service on my OS ( WinXP ), So now my programs run without any problem.
The problem is the Emulator use TCP/IP for transfering files between PPC and PC, and now I'm not able to use ActiveSync to connect to PPC 
How can I get ActiveSync to work with Emulator ?!
Regards,
Hadi

Read this article:
Migrating to the eVC 4.0 Environment[^]
Check the section on "ActiveSync Via Ethernet":
You can now connect ActiveSync to the emulator without a loopback serial cable. Compared to the previous version of the emulator this is faster and configuration is simpler, and you do not need a loopback cable and a PC with two serial ports. Now you can more easily test your desktop installations, ActiveSync filters/providers, and RAPI applications against the emulator. (...)
You can follow the configuration link here:

Dear João,
Thanks alot for help

Hi~
However, when you config the virtual switch in eVC++, the emulator can be connected with activesync only when the emulator is launched by eVC++. If the emulator is launched by VS .NET, it still cannot be connected with activesync.

I recomend qt if you are willing to stick with C++ only for the GUI. (can mix C code in elsewhere of course, just not the GUI). Worth the price in my opinion, but I can't convince the boss of that... http://www.trolltech.com/
wxWidgets is another common C++ toolkit, which is nice enough and free. Normally allows your application to look like it was designed for that platform. (looks like a mac app on Macs, windows apps on windows) The license isn't a big deal. http://www.wxwidgets.org/
GTK is a free C tool kit (with some C++ wrappers that some hate and others love). http://www.gtk.org/
Java makes a claim to cross platformness and you can call native code if you jump through a lot of hoops. I don't recomend it, but you can make it work.
http://www.geocities.com/SiliconValley/Vista/7184/guitool.html has some interesting links on this issue, but I haven't explored it. Check out google too.
Watch the licensing on the free toolkits. So long as you are aware of what is allowed and what is required, it isn't a big deal. Not watching them could end up digging a big hole.

Hi all,
I would like to ask a question as below,
My software is composed of a main C# program with some other c# dll as components. In the first round, I will install all the stuff on the machine.
Then after sometime, I need to install some additional dll to work with
the main C# program. How can I do that ? Is that possible in C#.Net framework ?
Thanks

Hi there,
I'm a new developer in .Net platform. I have implemented a code that runs at a Pocket PC 2002 platform. This is the client part , no problem. It saves some data such as names and adress information in XML document. The question is i want to send this data to a PC and upload necessary things. But i dont know how to start. the thing is just simple to upload XML file from PDA to PC or visa-versa. I couldn't find an article about this staff.if any one can tell me how to that or advises some article or site I will be glad. Thank you.

Look at the Activesync options.
There is a setting to enable Files to be synced.
If this is active, there will be a folder in your My Documents (ie "POCKET_PC My Documents".
This is a shadow folder of your ppc My Documents.
Activesync tries to keep this folder in sync.
So, anytime you cradle your ppc, or update the folder, it should be quickly up-to-date.

Hi all ,
i'm trying to realize a CF C# application that uses udp protocol and multicasting on address 224.0.1.84.
I need to have different sockets that reuse the same address and port, so i need to set the reuseAddress parameter with the setSocketOption function to true.
Unfortunely there is a bug in the API and the function with such a parameter doesn't work.
As Microsoft say you can work around this problem calling directly the CE API with the P\Invoke way.
I tried to do so, but with no result.
I always obtain error "10038" from the CE function setsockopt, which means that the function does't recognize the pointer passed a socket pointer. I'm sure i'm passing a valid socket pointer.
This is my code..
[DllImport("Winsock",EntryPoint="setsockopt", CharSet=CharSet.Unicode, SetLastError=true)]
public extern static int setsockopt(IntPtr _sock, SocketOptionLevel level, SocketOptionName name, byte [] byte_val, int int_val);
...
Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
IntPtr _sockhandle = sock.Handle;
MessageBox.Show(_sockhandle.ToString(), "socketHandle..");
if(this.setReuse(_sockhandle))
{
MessageBox.Show("setReuse OK!!");
....
}
...
private bool setReuse(IntPtr _sock)
{
int rs = 0;
try
{
Byte[] one = new Byte[1];
rs = setsockopt(_sock, SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, one, 4);
}
catch(Exception e)
{
MessageBox.Show(e.ToString(), "setReuse error..");
}
if (rs == mySOCKET_ERROR)
{
MessageBox.Show("setReuse error: " + rs.ToString() + " - " + Marshal.GetLastWin32Error().ToString());
return false;
}
else
{
MessageBox.Show("setReuse OK: " + rs.ToString());
return true;
}
}
What is wrong?
I tried too to call the CE API socket function in order to obtain a socket handle..
[DllImport("Winsock",EntryPoint="socket", CharSet=CharSet.Unicode,SetLastError=true)]
public extern static IntPtr mySocket(int af, int type, int protocol);
using it in this way
IntPtr _sockhandle = mySocket(2, 2, 17);
and passing it to the setsockopt..
in this way the function works, but now how can i associate this handle to a CF socket?
The socket.handle property is readonly and there is no constructor to create a new socket from a IntPtr handle..
Thank you very much!!

I'm a newbie trying to develop a client application to connect via a socket to a device connected on COM1. If I connect to a server on my host machine the standard SDK emulator connects OK. When I specify the device IP address that is connected to COM1 and try to connect to it, the emulator fails to connect.
Any help is appreciated !

Hello there,
In some occasions I used to use the Beep function in my programs for fast and easy sound-generation. I noticed now however that that doesn^t seem to be supported by PocketPC`s.. Is there an easy alternative for that?
In other words is there an easy way to sound a beep without having a wav file or any other sound file?
Regards,
Davy

I am new to the world of Pocket PC's and I have downloaded several example projects from the net only to find they will not load.
I am using Embedded VC++ 4 and the projects that don't load have the 'vcw' extension. They report many files that cannot be found, mostly .h and .rh, and .ico, then the compile option is greyed out on the menu.
What am I doing wrong? Any ideas?
Many Thanks,
Ali

I have to use legacy C code, where functions understand nothing else but char*
So the question is, what is the best way to convert the char* to unicode strings, to be displayed in a message box, or set in an CEdit control for example.

You can use the A2W macro but remember to state USES_CONVERSION within the function that uses the macro.
USES_CONVERSION;
...
wide = A2W(ascii);

as i know, we may use image data type to deal with blob.
but the problem is, how can i insert the bytes to the database?? 
i have tried the follow code segment, but it doesn't work
SqlCeCommand addPic = conn.CreateCommand();
addPic.CommandText = "INSERT INTO photoTable (Photo) VALUES(@Photo)";
SqlCeParameter picParam = addPic.Parameters.Add("@Photo", SqlDbType.Image);
picParam.Value = GetPhoto(photoFilePath);
public static byte[] GetPhoto(string filePath)
{
FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
byte[] photo = br.ReadBytes((int)fs.Length);
br.Close();
fs.Close();
return photo;
}
thanks

Does anyone know of a company that makes instrumentation widgets / gadgets for the CE .Net 4.2 platform? I'm looking for controls (LED indicators, bar graphs, analog gauges, etc.) that I can have run in an operator interface (LCD panel) used on a manufacturing plant floor. The application in the operator interface is being developed in embedded Visual C++. Thanks for any help!
