CEComCLient.dll
(x86 version for the emulator)
To install it copy it to the emulator and run regsvrce.exe to register it. |
COM Class that implements the ASTA SkyWire Library on |
Version available that compiles under Win32 also! |
| eVBSQLClient |
Sample eVB application |
Shows how to fetch server metadata information and EXEC and Select SQL |
| AstaADOWirelessServer |
Asta ADO Server to work with sample SkyWire clients |
This server uses ADO but ASTA has servers native servers for Oracle, MySQL and just about any other database you
can think of. |
| AstaSkyWireServer |
Sample non-Database debug server to see the internals of the ASTA client messages sent to the server. |

| AstaDLL.dll |
DLL Library that contains the implementation of the ASTA SkyWire Library that must be loaded on the WinCE device
or the emulator. |
Make sure it is in the path of any Wince Exe's. |
| AstaDLL.h |
Header file for AstaDLL. |
|
AstaSQL
|
AstaSQL demo.
|
Simple project that shows how to get tablenames, fieldnames, and execute exec and select SQL against a remote SkyWireServer.
|
SignCap
|
Digital Ink example showing how to capture a signature and send it to a remote server and display it.
|
|
| SkyWireTestClient |
Shows the built in abilities of SkyWire Servers and the client including signature capture with it being displayed
at the server.
Emulator Version
ARM Version for IPAQ
SH3 Version for HP Journada
MIPS Version |
download the server also |
| Delphi SkyWireTestClient |
Delphi Win32 client that can be run against the same server and implements the SkyWire client abilities through
the AstaServerSocket.OnCodedParamList call. |

Server Side
The TAstaPDAServerSocket, which descends from the TAstaServerSocket, provides support for Palm, WinCE and Linux
PDA Clients. Below is a description of the additional events available for the TAstaPDAServerSocket.
There are several additional events coded on the AstaPDAServerSocket in order to support remote PDA Clients
OnPdaParamList
This is the most important event as all the SendParamList calls from PDA clients will flow through this event.
The MsgToken comes from the remote Client call and if there is any kind of Error on the server just send a non-zero
value back in PdaSendParamList.
procedure TForm1.AstaServerSocket1PDAParamList(Sender: TObject;
ClientSocket: TCustomWinSocket; PDAid, MsgID, MsgToken: Integer;
P: TAstaParamList);
var
Error:Integer;
begin
Error:=0;
case MsgToken of
1001: Error:=DoPDAServerTime(ClientSocket, P);
1003: Error:=DoPalmSQLSelect(ClientSocket, P);
1004: Error:=DoPDATables(ClientSocket, P);
1005: Error:=DoPalmExecSQL(Clientsocket,p);
1006: Error:=DoPDAFields(ClientSocket, P);
1010: Error:=DoPalmMultiSQLSelect(ClientSocket, P);
1011: Error:=DoPDASelect(ClientSocket, P);
1012: Error:=0DoPalmExecSQLParamList(ClientSocket,p);
else Error:=DoPDAServerTime(ClientSocket, P);
end;
AstaServerSocket1.PDASendParamList(Error, ClientSocket, P);
end;

Client Side Example
Below is a small code example of creating an AstaConnection and connecting to a remote Asta SkyWire
server from the Digital Ink demo client.
AstaHandle Params = AstaParamLstCreate();
AstaParamLstSetLongInt(Params, 0, total_pixels, TEXT("Total"));
AstaParamLstSetBlob(Params, 1, tlist, total_pixels * 3, TEXT("Sequence"));
AstaHandle conn = AstaClConvCreate();
if (conn)
{
if (AstaClConvOpenConnection(conn, AddressBuf, Port))
{
bool sent = AstaClConvSendParamList(conn, MsgID, Params);
AstaParamLstDestroy(Params);
if (!sent)
{
int i = AstaClConvGetLastError(conn);
MessageBox(0, TEXT("Failed to send data"), NULL, 0);
}
AstaClConvReceiveStream(conn, &tlist, &tlsize);
AstaClConvCloseConnection(conn);
}
else
{
AstaParamLstDestroy(Params);
MessageBox(0, TEXT("Failed to connect to server"), NULL, 0);
}
}
AstaClConvDestroy(conn);
