I repass it and it's works, thanks!. Is there a easy way to hide the below bar (where the SIP button is) in all the application? I suppose at the beginning...I try it in many ways and wrong...

It's better than I hide this bar in each "Activate Message"...

How to add SDK on eVC++4.0

Hello everybody,

I have made some applications in eVC++ 4.0 for different device types. But now I got a new device which uses a different SDK for which I wish to compile my app. I can`t find however how I can add this SDK selection in the combobox of eVC++ . I can only see the ones I selected when creating the workspace (before I knew I would ever need this SDK), but I can`t see anywhere a menu point or dialog which allows me to add an SDK selection for the project.
Do I have to recreate my workspace now just for this one SDK or is there a way to add it to my existing workspace afterall???

Thanks for any help you might offer,

Greetings,
Davy

Have you installed the new SDK? First I would read in microsoft web if it is compatible with eVC++. Once installed, it must appears in the combo menu in eVC++ if it is installed correctly, I think...

Javier

Thanks for the reply,
Maybe I was a little unclear in the exact explanation.
Yes, I installed the SDK. The new projects I create have the SDK selectable in the combobox. However, my old project that I created before I installed the SDK do not have it. So the problem lies there.
Some projects are quite big, so it would take me a some time to recreate them...

Thx for any suggestions!!!

Hi,
Try one of these:
1)Build->configuration
than try to add or choose the right one.
2)Build->Set Active Platform.
3)Tools->Configure Platform Manager.

GoodLuck,

struct problem

Hi, I have the following piece of code:

BD_ADDR direccion;<br />
direccion.LAP=0x19C4BB;		//24bit LAP (Lower Address Part)<br />
direccion.UAP=0x37;			//8bit UAP (Upper Address Part)<br />
direccion.NAP=0x0080;		<br />
<br />
PORTEMUPortParams pp;<br />
memset (&pp, 0, sizeof(pp));<br />
pp.channel = 0;<br />
pp.device = (BD_ADDR) direccion;           //THEY'RE THE SAME TYPE!!WHY NOT RUN?<br />
pp.uiportflags = RFCOMM_PORT_FLAGS_REMOTE_DCB;

where BD_ADDR is a struct type according to MSDN web:

#pragma pack(push, 1)<br />
  typedef struct __bd_addr {<br />
  union {<br />
    struct {<br />
      unsigned int LAP : 24; <br />
      unsigned int UAP : 8; <br />
    };<br />
  unsigned int SAP; <br />
  };<br />
  unsigned short  NAP; <br />
  } BD_ADDR;<br />
#pragma pack(pop)

The problem is when I compile the project appears the next error that I dont
understand:
- Error in line """pp.device = (BD_ADDR) direccion;"""

error C2679: binary '=' : no operator defined which takes a right-hand <br />
operand of type 'struct _BD_ADDR' (or there is no acceptable conversion)

Any suggestion??

Thanks.

You can look at:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wcecomm5/html/wce50conCOMPortEmulationFacility.asp

The type is BD_ADDR, they're the same type, so I don't understand the error.

Maybe this help (the web above) is for Windows CE and I'm developing for Windows Mobile 2003 SE, with the following software:
- Embedded Visual C++4 and his service pack 4.
- Microsoft Pocket PC 2003 SDK.

Could it be a problem? Can I develop an application for "making a virtual serial port" via bluetooth with this software?

Thanks in advance.

Hi,
Maybe it's too late,but take a look on "Bt_api.h" and you will see that the type of pp.device is not BD_ADDR - but BT_ADDR.
anyway - i have the same problem:
i need to set up BlueTooth comunication between my PDA and another device
and i want to use a virtual COM port,but i can't create one.
my problems are:
1.i can't convert BD_ADDR to BT_ADDR.
2.i can't find the device dll.

can you help me?

Best regards,
Eli

Hi, not sure if I undertand very well your question...
But if you are asking how to communicate in BlueTooth using a virtual COM port, it is in fact exactly the same than using a standard COM port. You open it with CreateFile (providing the correct Port name) and then you send/receive data using WriteFile/ReadFile functions.

If this was not what you were asking for, try to be more precise in your question.
Hope this helps

Using Visio 2000 with eVC ?

Hi There,

I'm using eVC 4.0 and have the Visio 2000 version. I need to document my
program, so I thought that Visio was the right tool and I thought that it
would be an easy task for Visio to read the source code and automatically
create the UML class diagram like it is with the "normal" Visual C - but...
I can't find a way to do it! Are there anyone who will be able to give me a
good advice or who knows how to document ones progream in an easy way - I
highly appriciate any help!

If you are making an application in "Microsoft embedded Visual C++" you can test it in the emulator compiling it and targeting the project to the emulator (maybe first you must configure the emulator connection in "tools->configure platform manager" menu).

If you have an executable application and you want to download it to the emulator you must configure the "active sync" program to emulate that "pocket PC Emulator" is a real device connected to the PC. In the "Microsoft embedded Visual C++" Help explain how to do it, but I try it once I couldn't (you must configure the emulator connection with active sync in "tools->configure platform manager" menu and so on).

CFile C++ exceptions in EVT3.0

Mike Landis4-Nov-04 8:56

Mike Landis

4-Nov-04 8:56

I am writing for PocketPC 2002 using Embedded Visual Tools 3.0 (EVT3.0). The on-line documentation for CFile::Write() says "Write throws an exception in response to several conditions, including the disk-full condition." When I compile a try{ cfile->Write(...) } catch{...} code segment, the compiler flags the first of several cfile->Write() statements with: "... warning C4530: C++ exception handler used, but unwind semantics are not enabled. Specify -GX". My problem is where to insert this switch in the EVT3.0 environment?

I've found prerelease MSDN documentation on Structured Exception Handling <http: msdn.microsoft.com="" library="" default.asp?url="/library/en-us/dv_vccelng4/html/elgrfStructuredExceptionHandling.asp">, which says "Structured exception handling works with C and C++ source files. However, it is not specifically designed for C++. Although destructors for local objects will be called if you use structured exception handling in a C++ program (if you use the /GX compiler option), you can ensure that your code is more portable by using C++ exception handling. The C++ exception handling mechanism is more flexible, in that it can handle exceptions of any type." BUT, I think they're referring to Visual Studio 5 or 6, which has a slightly different Project interface than EVT3.0.

I also get the following linker errors due to the try/catch segment:
"error LNK2001: unresolved external symbol "const type_info::`vftable'" (??_7type_info@@6B@)
error LNK2001: unresolved external symbol ___CxxFrameHandler"

Does anybody know how to make EVT3.0 happy here?

Thanks

You don't because eVC++ 3.0 does not support C++ exceptions, only structured exceptions.
