Hi,
I'm trying to set up BlueTooth comunication between 2 devices,by using Virtual COM Port,with the RegisterDevice() function.
The problem is that the last parameter required the BD_ADDR(BlueTooth address) of the device i want to connect to.
How can i get the asddress????
Regards,
Eli

BTH_ADDR which is a MAC address,
not BD_ADDR that is an IP address
but i don't remember how

First,thanx for your prompt reply.
According to MSDN:
When the client or server starts, it creates a COM port to associate
with the Bluetooth stack in the following manner:
HANDLE h = RegisterDevice (L"COM", index, L"btd.dll", (DWORD)&pp);
For the client, the Bluetooth server address (pp) is passed into the
pp.device member in the PORTEMUPortParams structure(and pp.device type is
BD_ADDR).
Anyone???
Regards,
Eli.

Hi
Does anyone know how I can find out what exception has actualy
been thrown when I catch it with catch (...) block.
/Per
|
|
|
|
|
all the other exceptions that has not been catched with previous catch block. you can imagine its behavior like the default statement of a switch...

I woul'd like to catch the exception, but I don't know what type it is. Can I figure that out in some way?
|
|
|
|
|
|
I don't think so either. In cases where you specify the exception type, you can do something like catch(CexType& ex)
and that gives you an object you can interrogate, perhaps using RTTI, but in the ellipsis case, there's nothing to help you.

Most frameworks provide a base class that all exceptions should be derived from for this reason. For example MFC has a CException class.
In all but the most exceptional (pun intended) circumstances exceptions should derive from std::exception, the exception base class for the C++ Standard library. Rather than catch(...), use catch(std::exception& )

I am using a dll that is returning a byte buffer and bitmapinfoheader
my front end is mfc appliction dialog box and now i want to draw that image byte buffer (that is accompanied by bitmapinfoheader)to my dialog box also the image is very large so i wan to scale it inorder to draw.
can any body help me

|
|
|

I know it's a little old, but this function works and is pretty easy to use.
DrawDibDraw()

|
|
|
|
use BitBlt().....
that might help.....
happy programmin.....
cheerz.....

Look the scale is almost irrelivante (does not matter).
Never mind (I am not in the mode)! If you have the bitmapinfoheader, then you should know what (should) follow.
I started to go into all the ways this could be handled, but blank that, either you are recieving a bitmap (or DIB) or not (or some other [none-Window} reconized protocal, or you are not).

Hi everyone, i have a wrapper calss of std::list<T> that compiles well under VC6.0 but under VC7.1 gegerates syntax error. the listings of the file are as follows:
.h file looks like this
template <class T> class myList
{
public:
list<T>::reference front();
protected:
list<T> m_lItems;
};
and .cpp file looks like this
template <class T> list<T>::reference myList<T>::back()
{
list<T>::reference r = m_lItems.back();
return r;
}
any help why this code is being compiled in VC6 but not in VC7.1.
the error it generated is 
error C2143: syntax error : missing ';' before '<

Well, the class declaration doesn't have a back() method, so that's an error. You also need to have the method's code in the header file, or you'll get linker errors. But to fix the error you posted about, remove the <T> as shown:
template <class T> list<T>::reference myList<s><T></s>::back()

This my first messege in my first day at this perfect site
I have a problem using the Friend Function in microsoft visual C++ .I have a multifile program contains statements like this
friend bool operator < (const tenant&, const tenant&);<br />
bool operator < (const tenant& t1, const tenant& t2)<br />
{ return t1.name < t2.name; }
compiler flags me errors like these:
error C2593: 'operator <' is ambiguous
error C2248: 'name' : cannot access private member declared in class 'tenant'
Can any one help me ..
please my friends.

Well, I do not know if this helps at all but both the declaration refer to the same thing, I think, (no wonder the compiler upset).
//declaration in class tenant within a header file.
friend bool operator < (const tenant&, const tenant&); // friend to whom?
//definition in the source file.
bool operator < (const tenant& t1, const tenant& t2) // may not care
{ return t1.name < t2.name; }
I do not know the symantics, but this is wrong unless you know who your fiend is.
I'll assume, yor wrote the version:
//declaration in class tenant within a header file.
friend bool operator < (const tenant&, const tenant&); // friend to whom?
That should not be needed it the version:
//definition in the source file.
bool operator < (const tenant& t1, const tenant& t2) // may not care
{ return t1.name < t2.name; }
Already exists.

got a problem in the following code
void main()
{
IGraphBuilder *pGraph = NULL;
IMediaControl *pControl = NULL;
IMediaEvent *pEvent = NULL;
// Initialize the COM library.
HRESULT hr = CoInitialize(NULL);
if (FAILED(hr))
{
printf("ERROR - Could not initialize COM library");
return;
}
// Create the filter graph manager and query for interfaces.
hr = CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC_SERVER,
IID_IGraphBuilder, (void **)&pGraph);
if (FAILED(hr))
{
printf("ERROR - Could not create the Filter Graph Manager.");
return;
}
hr = pGraph->QueryInterface(IID_IMediaControl, (void **)&pControl);
hr = pGraph->QueryInterface(IID_IMediaEvent, (void **)&pEvent);
// Build the graph. IMPORTANT: Change this string to a file on your system.
hr = pGraph->RenderFile(L"C:\\Example.avi", NULL);
if (SUCCEEDED(hr))
{
// Run the graph.
hr = pControl->Run();
if (SUCCEEDED(hr))
{
// Wait for completion.
long evCode;
pEvent->WaitForCompletion(INFINITE, &evCode);
// Note: Do not use INFINITE in a real application, because it
// can block indefinitely.
}
}
pControl->Release();
pEvent->Release();
pGraph->Release();
CoUninitialize();
}
the compliler says, "Unresolved externals;
CLSID_FilterGraph
IID_IMediaEvent
IID_IMediaControl
IID_IGraphBuilder

I assume you included something like dshow.h or your code wouldn't have compiled. Try including thoe header files that define those guids in a single source file in your project like this:
Assume this were a file called guids.cpp in you project.
#include <initguid.h>
#include <dshow.h>
#include <uuids.h> // or maybe just include these instead of dshow.h
#include <control.h>

Sorry about that <'s got treated as html tags.
