Hi, in my MFC app I have a template class like this:
<br />
template <typename BASE><br />
class CBWnd : public BASE {<br />
public:<br />
CBWnd(){};<br />
CBWnd(LPCTSTR s, CWnd *p):BASE(s, p){};<br />
CBWnd(UINT n, CWnd *p):BASE(n, p){};<br />
CBWnd(LPCTSTR s):BASE(s){};<br />
CBWnd(UINT n):BASE(n){}; <br />
};<br />
When I derive a class from an MFC one a make this:
<br />
class CMyButton : public CBWnd < CButton > {};<br />
<br />
class CMyDialog : public CBWnd < CDialog > <br />
{<br />
CMyDialog(LPCTSTR s, CWnd *p):CBWnd< CDialog >(s, p){};<br />
};<br />
In the contructors of CMyButton and CMyDialog I need to pass the parameters (for example the template ID and the parent window of derived a dialog) to the base class (CDialog, CButton and so on...that's why all constructors).
This code works fine on Visual Studio 6 but doesn't compile on Visual Studio 2003 because this compiler check all the CBWnd constructors (VS6 check only the used ones...)and if there isn't an implementation in the other classes (CMyButton, CMyDialog ecc...)
of the called one it generates an error...
Plz help me!

Shouldn't you be using:
template < typename BASE ><br />
class CBWnd : public BASE {<br />
public:<br />
CBWnd(){};<br />
...

That was only a problem in the code formatting (forgot spaces)...

Hi, all
recently i'm planing to make an ie plugin to prevent some(not all) scripts running on ie, or even disable download them from the web, i notice norton antivirus 2003 has some kind of function like that -- script blocking. i originally considered the BHO, but there isn't any events about for script running. anybody can let me know that? thanks.

Hello, following is my problem:
In Serial communication, I want to send and receive data of 9 dataBits. How should i set the DCB? And how can i get the 9th bit when receive.
Please , help me. Thanks.
|

|

There is no such thing 9 databits.
beware that:
When a DCB structure is used to configure the 8250, the following restrictions apply to the values specified for the ByteSize and StopBits members:
The number of data bits must be 5 to 8 bits.
The use of 5 data bits with 2 stop bits is an invalid combination, as is 6, 7, or 8 data bits with 1.5 stop bits.
Good luck!

|
|
We can set databits to 8, and set the dcb.parity to
MarkParity or SpaceParity as the 9th bit to send.
if dcb.parity equals markParity then the 9th bit is 1;
if dcb.parity equals spaceParity then the 9th bit is 0.

How can I know if there are modal dialog popup of some process?
|
|
|
|
|
Enumerate all of its children looking for dialog windows class.
BOOL
hWnd_Is_Dialog( HWND hWnd )
{
char szName[ 30 ];
return ( IsWindow( hWnd )
and GetClassName( hWnd, szName, sizeof( szName ) ) > 0
and strncmp( szName, "#32770", 6 ) eq 0
);
}
You might be able to just run this agains GetLastActivePopup() instead of enumerating all windows.

Hi all
Where can I find such an animal? (woohoo out u english man!!! ignore cricket comments). I have found 2 commercial tools. Glowcode - nice looking but cant handle program args well. And VTune from Intel, at a whopping ~200Mb, err no thanx.
I have tried gprof too, but that doesnt seem to link properly.
All I need it a list a functions, # times executed, avg exec time, total exec time, WITHOUT having to wrap every call in a "tag"/macro.
Thanks

Unfortunately that is the 127mb (ok its not really 200mb) beast I was referring to, and with only 7 days to eval, I'm not sure I will have the file by then... The beauty of narrowband.

Linking problems with gprof are usually caused by not supplying the correct command line options to the linker.
Ran into this problem the other day on a Sun system (can't remember compiler version), compiled up the code using -xpg (profiling enabled) and it wouldn't link.. added -xpg to the link arguments and no problems.
Your problem could be something similar?

hi,
i am importing msacc9.lib and using transfertext method of Access application objects DoCmd object to import a tab delimited file into a table like this .code works fine with access 2000.but when i use access 97.It throws an exception saying : "Invalid number of parameters".
I am struk with this problem unable to understand why it is giving problems.Any idea will be highly appreciated.
My code looks something like this......
try
{
acc::DoCmd d1 = m_pAccessApp->GetDoCmd();
d1.TransferText(0,COleVariant(_T("ID Import Specification")),COleVariant(_T("IDTable")),
COleVariant(sTempDatabase),
COleVariant((short)1),
COleVariant(_T("")),
COleVariant((short)0, VT_I2));
catch(CException *pException)
{
TCHAR lpszError[1000];
pException->GetErrorMessagelpszError,1000);
AfxMessageBox(lpszError);
throw pException;
}
Regards.

I've been programming in straight C (Borland then Visual C) for about 15 years now, mostly command line utilities. I've known I need to get into C++ and have tried several times, but never been able to get the hang of it because I keep falling back to C.
What am I doing wrong? Maybe I don't want to give up all the code fragments I amassed over the years or I haven't found the right book.
Any ideas?

Unless you have a specific need to learn C++, try having a quick look at C# or Java. You don't need to become an expert but they will teach you how to think OO which is probably the number one problem C programmers have when trying to make the transition. But unlike in C++, you don't have the option of reverting back to your old ways

I would highly recommend against Java and C# for a C programmer migrating to C++. They are pseudo languages with a heavy layer of abstraction between you and the opcode and or the API if you use windows. They do not allow for direct casting, memory access, or access to the true low level API that we all enjoy using C++.
I STRONGLY recommend this book for the core differences between C and C++ programming
O'Reilly Publishing - C++: The Core Language[^]
and this book if you need to learn the Windows API
MSPRESS - Petzold, Programming Windows[^]

This is *exactly* my point. As a C programmer, he presumably knows all this stuff already. What he is probably having trouble with is all the higher-level abstraction stuff.

memory allocation and de-allocation are very different in C++ than in java or javaplus(C#).
In C++ you have virtual functions, oo class casting, class pointer indirection, classes retrieved by direct API, such as fromhandle, and others.
Learning C# or java will not prepare a C programmer for C++ properly.
I still think your comment would lead the writer down the wrong track for what he's looking for.
I'll restate my suggestion to pick up O'reilly publishing's C++: The Core Language[^]
The reason?
That book in particular goes into great detail about how a C programmer may migrate to C++. It does NOT go into detail about platform specific API. It's purely for migration from C to C++.
Revised: In addition, when he begins to look at the C++ threading models, he will find they are much, much different from Java which extends the thread class or C#. There are a million reasons not to learn C++ OO by learning java and C# i can think of, but I won't list them all.
