New Language for creating Mobile Applications

If you find code warrior , J2me or Visual Studio are too complicated and you feel that you need to learn just one tool that is a lot easier, instead of three then, look up the Mobile Application development tool called GoDb which is similar to VB in look and feel but allows you to create Powerful Mobile Applications for PALM, POCKET PC, Symbian , Nokia. The tool comes with it own IDE , Gbasic - a language similar to VB ( infact if you know VB you can start programming in it instantly) and Simulators and Sync server .

Hi all,

is dynamic loading of appDomains also work in compact framework .net ?

I have run example in dynamic loading in .net framework,
but since compact framework dont have AppDomainSetup Class,
so what can I do ?

The code in dynamic loading in .net framework is in
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dncscol/html/csharp05162002.asp

but when the port the code to compact framework, the code doesn't work coz AppDomainSetup Class is missing in .net CF.

Can anyone point to sample code or articles on it ?
Thanks

Zone Colour Filling - Drawing

Hi all,

I've run into a little problem, I'm drawing a zone on a CDC and would like to fill the zone in with a colour, most likely black.

I collect the points and store them in a CArray of CPoints and draw the zone like...

<br />
typedef CArray<CPoint, CPoint&> CPointList;<br />
CPointList Points;<br />
<br />
// --- stuff<br />
<br />
int numPoints = Points.GetSize();<br />
<br />
if(numPoints>1)<br />
{			<br />
    for(int i=0;i<numPoints-1;i++)<br />
    {<br />
        pDC->MoveTo(Points.GetAt(i).x,   Points.GetAt(i).y);<br />
        pDC->LineTo(Points.GetAt(i+1).x, Points.GetAt(i+1).y); <br />
    }<br />
}<br />

This just draws the zone, I did try using Polyline() and PolylineTo() but the starting point is always coming from the side of the display instead of the first point in the array, the code I used with the Poly methods was something like...

<br />
int numPoints = Points.GetSize();<br />
<br />
if(numPoints>1)<br />
{			<br />
    CPoint* pts = new CPoint[numPoints];<br />
<br />
    for(int i=0;i<numPoints-1;i++)<br />
    {<br />
        pts[i].x = Points.GetAt(i).x;<br />
        pts[i].y = Points.GetAt(i).y;<br />
    }<br />
<br />
    pDC->MoveTo(pts[0].x, pts[0].y);<br />
    pDC->PolylineTo(pts, numPoints);<br />
    //pDC->Polyline(pts, numPoints);<br />
<br />
    delete [] pts;<br />
}<br />

and even with PolyPolygon() i got very strange drawings using the following code

<br />
int numPoints = Points.GetSize();<br />
<br />
if(numPoints>1)<br />
{			<br />
    CPoint* pts = new CPoint[numPoints];<br />
    int tmp[2];<br />
<br />
    tmp[0] = numPoints;<br />
    tmp[1] = numPoints;<br />
<br />
    for(int i=0;i<numPoints-1;i++)<br />
    {<br />
        pts[i].x = Points.GetAt(i).x;<br />
        pts[i].y = Points.GetAt(i).y;<br />
    }<br />
    <br />
    //pDC->MoveTo(pts[0].x, pts[0].y); //  even tried wit this<br />
    pDC->PolyPolygon(pts, tmp, 2);<br />
<br />
    delete [] pts;<br />
}<br />

If anyone has some input which could help I'd be very intrested to hear it. Also I'm working with the PocketPC SDK so things like FloodFill() cant be used ;(

No, they can't be used. But they can be implemented...

Thanks João,

I have since added the class to my project but have run into a little problem.

My project has 2 CDC's, one is in the main View class and the other I use in my Zoning Class.
When I draw my zone I draw the zone on both CDC's but the second CDC in the Zoning Class will get filled in.
I then use this CDC as a hidden CDC to check if I'm still in a zone, using the likes of GetPixel() to find out if I have left the zone.

My problem now is that it's always returning true, as in I have left the zone, so I now need to display the second CDC to the screen to verify that the zone has been set up right, but when I do I just get a blank display, all white.

I'm using code like the following...

<br />
ColorZone = new CDC();<br />
ColorZone->CreateCompatibleDC(NULL);<br />
int numPoints = Points.GetSize();<br />
<br />
if(numPoints>1)<br />
{<br />
    for(int i=0;i<numPoints-1;i++)<br />
    {	// draw outling<br />
        ColorZone->MoveTo(Points.GetAt(i).x,    Points.GetAt(i).y  );<br />
        ColorZone->LineTo(Points.GetAt(i+1).x*, Points.GetAt(i+1).y);<br />
    }<br />
		<br />
    if(CZone::IsComplete)<br />
    {   //fill in zone<br />
        CPoint point = Points.GetAt(0);<br />
        point.x+=1; // just added to move off outline border, fix later on<br />
        point.y+=1;<br />
        CRect		rect;<br />
        GetClientRect(NULL, &rect);<br />
        CFloodFill<CDC, COLORREF>	flood(*pDC, rect);<br />
        flood.Fill(point, RGB(255, 0, 0));<br />
        <br />
        // display on main CDC - debugging only<br />
        CMyBaseView* pView = (CMyBaseView*)((CMainFrame*)AfxGetApp()->m_pMainWnd)->GetActiveFrame()->GetActiveView();<br />
        pView->GetDocument()->mapDC = ColorZone;<br />
    }<br />
}<br />

As I'm very new to PocketPC development I'm a little unsure if the above code should do what it's meant to be doing, any input would be grateful!

Thanks again,
ar

Hi,

I have Embedded 4 and it it has no option to open solution files - only VC 6.

What are my options? The app is not .NET just written with .NET IDE.

What is the quickest way to port it to Embedded VC++ 4.0?

Thanks,

Hw do I setup a direct pc2pc connection on COM port ??

glweid14-Jun-04 5:08

14-Jun-04 5:08

I'm porting an existing NT application to Pocket PC. On NT/XP I setup a direct pc to pc connection type for the application to establish a PPP connection via RasDial() and then connect a socket to get TCP/IP up.

I would like to use port the existing code but on the Pocket PC connection settings there is no direct connection allowed, only a Hayes Compatible modem option which dictates I need a modem connected to the COM port.

Is there anyway to setup a direct connection or change the RasDial() settings to use a VPN connection to the COM port to setup PPP ??

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.

PPC 2003 Emulator & ActiveSync

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 Frown | :(

How can I get ActiveSync to work with Emulator ?!

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:
Using ActiveSync over Virtual Switch[^]

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.
