Hi, i've two mobile application, one in c++ and the other in c# that exchange a structure with wm_copy_data.
If i have a simple int inside the struct, everything work fine, but i have problem with the correct struct definition in c# code.
Here is the c++ app code:
typedef struct tagMYRECASR
{
char roName[100];
char roRole[100];
char rpName[100];
} MYASR;
COPYDATASTRUCT MyCDS;
MYASR MyRec;
char *roName;
char *roRole;
char *rpName;
CString rp = _T("rp_it-it");
CString vbRoName = rp;
vbRoName += "/";
vbRoName += grmName;
CString vbRoRole = _T("");
CString vbRpName = _T("");
ConvertToMultibyte(&roName,vbRoName);
ConvertToMultibyte(&roRole,vbRoRole);
ConvertToMultibyte(&rpName,vbRpName);
strcpy(MyRec.roName,(const char*)roName);
strcpy(MyRec.roRole,(const char*)roRole);
strcpy(MyRec.rpName,(const char*)rpName);
MyCDS.dwData = 1;
MyCDS.cbData = sizeof( MyRec );
MyCDS.lpData = &MyRec;
HWND window = ::FindWindow(NULL, _T("ManageWindow"));
if(window!=NULL) {
::SendMessage(window, WM_COPYDATA, (WPARAM)(HWND) window, (LPARAM) (LPVOID) &MyCDS );
In c# i tried to define the structure in this way:
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)]
struct UserData
{
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 100)]
public string roName;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 100)]
public string roRole;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 100)]
public string rpName;
}
and in many other way, but it doesn't work
any idea? consider me a newbye.
thanks in advance

i write code in C# based on WinCE, and hardware is ARM
each time, i need to debug code when linked with my ARM device,it's very slowly.
whether there is another way to debug more quicky? 
|
|

If your CE device has WiFi and if it is connected to the same network as your PC then you may want to turn the WiFi adapter off. If it is on then many times debugging will occur over the WiFi adapter instead of the USB connection and that makes debugging extremely slow.

Hi 
The snappiest way involves some platform API calls. Check out the VERY good IPhone clone articles here on CodeProject. The guy has made the code for this very easy to reuse.
Ciao,

There's a native event that is triggered when the device is cradled. IT is not directly exposed in C#. But I made use of it in thie article: Automatically Starting Your Application on Windows Mobile[^]
While the article is centered around automatically starting a program you can also use it to get notification that an event has occurred if your program is already running.

Hi
Is it possible to run java programs on Windows CE ?
thank's
|
|
|
|
|
It is possible, but you will need to find a Java Virtual Machine to put in your CE image. I can't say that I know of any from memory.

Hi! I'm new into drawing with Visual C++ MFC.
I've got an empty DIALOG where I load a floor layout (BMP resource) and I want to draw on it a dot indicating my position (using "SetDIBitsToDevice")
I call "Invalidate()" in another function when I get new coordinates to print on screen. Problem is that my PocketPC freezes every 3rd-4th time I run this function.
As I cannot borrow another PDA from anyone for now I would like to know if code is all right, or if there is any tricky command I'm using.
void CDisplayDlg::OnPaint()
{
CColoredDlg::OnPaint();
HBITMAP hBmpL1=::LoadBitmap(AfxGetResourceHandle(),
MAKEINTRESOURCE(IDB_DISPLAY_BITMAP));
CRect rc;
this->GetClientRect(&rc);
HDC hdc1 = ::GetDC(this->m_hWnd);
HDC hdcmem = ::CreateCompatibleDC(hdc1);
::SelectObject(hdcmem,hBmpL1);
::BitBlt(hdc1, rc.left, rc.top, rc.right, rc.bottom,
hdcmem,0,0,SRCCOPY);
BITMAPINFO BitmapInfo;
BitmapInfo.bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
CWinCEUnsupportedFunctions::GetDIBits(hdcmem, hBmpL1, 0, 0,
NULL, &BitmapInfo, DIB_PAL_COLORS);
BYTE* pBitData = new BYTE[36];
for(int i=0;i<36;i++)
{
pBitData[i]=8;
}
scale=3.3;
if(numPositions==1)
{
::SetDIBitsToDevice(hdc1, (int)(xcoord1*scale), (int)(ycoord1*scale),
6, 6, 0, 0, 0, 6, pBitData, &BitmapInfo, DIB_PAL_COLORS);
}
delete pBitData;
}
Thanks!

|

maybe you have a memory leak! Change this line to free up the whole array!
delete [] pBitData
|
|
|
|
|
|
I made a "dot.bmp" in resources and I'm showing it with "LoadBitmap". ^^
Maybe there's something I have to call after SetDIBToDevice?

Hi
I have following issues while working with KSOAP2.
I don’t know whether I am posting my query at correct location or not
I have a Web service written in JAVA, developed using Netbeanns 6.5 deployed on Jboss5.0
I have a J2ME client which gives a call to WS using KSOAP
I want to do following things:
send byte[] which is part of custom VO
Handle exceptions sent from server
How do I send the byte array
I read the things on http://ksoap.objectweb.org/project/faq/index.html
But I don’t know how to use it
private void callWS1() throws IOException, XmlPullParserException {
String endPointURL = new String("http://172.16.3.184:8080/CitiBankOnline/LoginService");
String nameSpace = new String("http://service.partner.com/");
SoapObject method = new SoapObject(nameSpace, "getDevice1");
DeviceCurrentActivityVO oDcavo = new DeviceCurrentActivityVO();
KeySet oKeySet = new KeySet();
byte[] oBytesArr=new byte[]{(byte)0x01,(byte)0x01,(byte)0x01,(byte)0x01};
String bytes = Base64.encode(oBytesArr);
SoapPrimitive oPrimitive = new SoapPrimitive (SoapEnvelope.ENC, "base64", bytes);
String szbytes = oPrimitive.toString();
oDcavo.setProperty("id", new Integer(12));
oDcavo.setProperty("name", "geetanjali");
oDcavo.setProperty("encKey", bytes);
oDcavo.setProperty("keySet", oKeySet);
method.addProperty("param", oDcavo);
oForm.append("Created soap object");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.bodyOut = method;
envelope.setOutputSoapObject(method);
new MarshalBase64().register(envelope);
HttpTransport ht = new HttpTransport(endPointURL);
oForm.append("Created transport");
ht.call("", envelope);
oForm.append("Called transport");
SoapObject soapResult = (SoapObject) envelope.getResponse();
int totalProperty = soapResult.getPropertyCount();
oForm.append("\nid = " + soapResult.getProperty(0).toString() + "\n");
oForm.append("\nPriority = " + soapResult.getProperty(1).toString() + "\n");
SoapObject oString = (SoapObject) soapResult.getProperty(2);
Object s = oString.getProperty("version");
oForm.append("version = " + s.toString() + "\n");
oForm.append("id = " + oString.getProperty("id").toString() + "\n");
String szBytes = oString.getProperty("encKey").toString();
byte[] oBytes1= Base64.decode(szBytes);
oForm.append("ENc Key = " +oBytes1[0]+ "\n");
Display.getDisplay(this).setCurrent(oForm);
}
And Vo luks like
public class DeviceCurrentActivityVO extends SampleVO {
private int id;
private String name;
public Vector oVector = new Vector();
KeySet keySet = new KeySet();
byte[] oBytes = null;
public byte[] encKey;
public Object getProperty(int index) {
switch (index) {
case 0:
return new Integer(id);
case 1:
return name;
case 2:
return keySet;
case 3:
return encKey;
default:
return null;
}
}
public int getPropertyCount() {
return 4;
}
public void getPropertyInfo(int index, Hashtable properties, PropertyInfo info) {
switch (index) {
case 0:
info.name = "id";
info.type = PropertyInfo.INTEGER_CLASS;
break;
case 1:
info.name = "name";
info.type = PropertyInfo.STRING_CLASS;
break;
case 2:
info.name = "keySet";
info.type = PropertyInfo.OBJECT_CLASS;
break;
case 3:
info.name = "encKey";
info.type = new byte[0].getClass();
break;
default:
break;
}
}
public void setProperty(String name, Object value) {
{
if (name.equals("name")) {
setProperty(1, value);
} else if (name.equals("id")) {
setProperty(0, value);
}
else if (name.equals("keySet")) {
setProperty(2, value);
}
else if (name.equals("encKey")) {
setProperty(2, value);
}
}
}
public void setProperty(int index, Object value) {
switch (index) {
case 0:
id = ((Integer) value).intValue();
break;
case 1:
name = ((String) value).toString();
break;
case 2:
keySet = (KeySet) value;
case 3:
encKey = (byte[]) value;
default:
break;
}
}
}
public abstract class SampleVO implements KvmSerializable {
public static final String NAMESPACE = "http://172.16.3.184:8080/CitiBankOnline/LoginService";
public SampleVO() {
super();
}
}
