You are violating the One Definition Rule (ODR)[^]. There are three ways around this:
The first is to move the function definition into the class definition (such functions are implicitly inline):
class A
{
public:
virtual void foo()
{
}
};
The second is to add the inline keyword to the function definition in your code as is:
class A
{
public:
virtual void foo();
};
inline void A::foo()
{
}
The third is to move the definition of the member function into a .CPP file:
class A
{
public:
virtual void foo();
};
void A::foo()
{
}
Also note that it's pointless to use the inline keyword on virtual functions as virtual functions need an address to put in the vtable[^] and thus will not be inlined anyway.

Hi,
I am using the IXMLDOM objects to create an xml file and write tags to this file.
I would like to create a tag <children count="2">, and under that write the names of the children <childname> value </childname>.
this should look as folowing:
<Root>
<Person>
<Name> value </Name>
<PhoneNumber> value </PhoneNumber>
<Children count = 2>
<childName> value </childName>
<childName> value </childName>
</Children>
</Person>
</Root>
1. Using IXMLDOMDocument or IXMLDOMNode, how do I add a node <Children count =2>, is this an attribute? How do I make sure that it is inserted under the <phonenumber> tag?
2. How do I add the sub nodes underneath <childName> value </childName>
If you could give me code examples tha twould be great.
I've tried all kinds of options using the IXMLDOM functiom and it doesn't work!!
Thanks.

In MDI Application i want only maximise and close button on my child windows and not minimise button.
I tried diff styles of the window in "PreCreateWindow" function, but i could disable the minimise button but couldnt hide it.
Is it because Window property has this limitation?
Can you please help?
Thanks
Regards,
Jigna

vote 5 for gray man.

I really cannot understand voting down, this time.
CLSID of an existing COM interface should NEVER change. Like the interface itself.
Anyway, thank you friend.
(BTW Why gray man?)

I think 1 was of a gold member because your rate is 3 if it was of a bronze member now it was 3.67(of course its my mind ) and thats right never changed and why gray 1=gray man and 5=red man  ).

My vote too, but the score didn't go way too much up as expected. Sad buggers vote down for no reason.

Of course, but you haven't supplied anywhere near the amount of information for us to help. For example, what framework did you use (if any) to make the DLL?

How do I convert from std::string to char* in C++?
|
|
|
|
|
std::string s = "Hello World";
char* psz = s.c_str();
|
|
|
|

I followed the same method. But the following code:
std::string path = dtCore::GetDeltaRootPath();
const char* exeroot = path.c_str();
strcat(path,"/");
strcat(path,"CharacterAnimation.exe");
result = system(path);
return true;
gives me the following errors:
error C2664: 'strcat' : cannot convert parameter 1 from 'std::string' to 'char *'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
.\GUI.cpp(195) : error C2664: 'strcat' : cannot convert parameter 1 from 'std::string' to 'char *'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
.\GUI.cpp(196) : error C2664: 'system' : cannot convert parameter 1 from 'std::string' to 'const char *'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
How do I resolve?

why are you using path instead of exeroot you just allocated ?
it's obvious you don't read error messages, or you don't understand what you're doing...
check your code again.
std::string path = dtCore::GetDeltaRootPath();
const char* exeroot = path.c_str();
strcat(exeroot, "/");
strcat(exeroot, "CharacterAnimation.exe");
result = <font color="red">system</font>(exeroot);
return <font color="red">true</font>;
BTW, you seem not to have takenn in account my previous remarks...

Now this line shows:
char* exeroot = path.c_str();
the following error.
error C2440: 'initializing' : cannot convert from 'const char *' to 'char *'

add const then, as std::string::c_str() returns const char*

I think you'll get buffer overruns that way.

That's assuming you cast away the consts so it even compiles.

Bad advice. The buffer returned from c_str is const and thus can't be modified. And it's wrong to cast away the const as it's const for a reason: the buffer used by a std::string need not be contiguous memory. If this is the case calling c_str makes a temporary buffer and copies the non-contiguous memory blocks into one contiguous memory block for you. It is not required to copy the blocks back. Also your code is in serious danger of causing a buffer overrun (if you made it compile by casting away the const): how do you know how big the buffer is?
Anyway the correct way is simpler, safe, works, is portable and requires no casts:
std::string path = dtCore::GetDeltaRootPath();
path += "/CharacterAnimation.exe";
system(path.c_str());
