I used ATL create a Dll project,
I want get current DLL directory, I used ::GetCurrentDirectory() API,
but I only get the EXE 's current path.
I want get Dll's directory
what can I do ?

GetModuleFileName will return the full path of the module you specify. If you give it NULL for the hInstance, then it will return the path of the main executable.

Thanks you get me this help ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)
I used GetModuleFileName() by your's suggest.
It's good

I know CFileDialog class is MFC Class,
But I want used this class in WTL project.
I include afxdlgs.h at my project but is error
"WINDOWS.H already included. MFC apps must not #include <windows.h>"
I want know have similar calss in WTL ?

I haved find similar class - CFileDialog in atldlgs.h
Thanks myself;P

Hey,
I am trying to use CString in my ATL IE Toolbar. I had some compiler errors and then read an article that said I had to include atlstr.h. I have VC 6.0 but cannot find atlstr.h, can anyone show me where I can get it or send it to me?
Thanks in advance.

Upgrade to VC7. It isn't available in VC6.

VC 7 has a shared CString class between ATL and MFC. Since you're using 6, you should use WTL, which has its own CString.
How do I use WTL when its programmed in ATL? Or are they almost the same? Sorry, I don't really know much about either of the languages.

Hey Guys,
I'm trying to port a plain WIN32 dll over to another system which uses ATL to implement the interface. I know nothing about ATL but I've sort of got it working aside from the fact I can't figure out how to get the HINSTANCE of my DLL.
The DLLmain does the following
CComModule _Module;
BEGIN_OBJECT_MAP(ObjectMap)
OBJECT_ENTRY(CLSID_My_Plugin, CMyPlugin)
END_OBJECT_MAP()
BOOL WINAPI DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID )
{
if (dwReason == DLL_PROCESS_ATTACH)
{
_Module.Init(ObjectMap, hInstance);
DisableThreadLibraryCalls(hInstance);
}
else if (dwReason == DLL_PROCESS_DETACH)
_Module.Term();
return TRUE;
}
I can see the _Module gets the HINSTANCE here but how do I get to it from the CMyPlugin class?
Cheers
James

_Module.GetModuleInstance();)

 Thanks. Didn't realise it was that straightforward.

I found a solution to build myDLL, using yourDLL, with /FORCE:MULTIPLE only...hope you got the problem...it was something like /Gw option but I dont have yourDLL code thats why I could this /FORCE:MULTIPLE only.
It kills me every time when I build it by saying" image may not run"
Is there any other solution to this?
part-2------------------------------------------------------------------------
In trying to use yourDLL in myDLL. I've declared it as private member and Initialized it one function, first function. It works fine here. When I call this existing object from second function, it says "cant read the memory". Of Course a test-client calls myDLL to raise these errors otherwise myDLL builds OK.
I'm always wrong....whats appropriate way?
thanx to HELPERS!
I'll pray for YOU!

What is the best way to define a map of string to CComPtr<iunknown> using MFC's CMap?
Best regards,

I'm trying to use a bitset that would be the key for a map.
Something like map< bitset<100>, CMyClass * >
The problem with that the bitset is not LessThan Comparable.
And I have no idea about how to compare two bitsets. I cannot convert to ulong since it is 100 bits! Anybody has already implemented a comparison operator for bitsets?
Help greatly appreciated!

The following is not the most efficient way, but it should work (not compiled it, expect typos):
template<size N>
int compare(const std::bitset<N>& x,const std::bitset<N>& y)
{
for(size_t s=N;s--;){
if(x[s]){
if(!y[s])return 1;
}
else{
if(y[s])return -1;
}
}
return 0;
}

Thanks, that looks good.
In the mean time, I found the Boost C++ library on http://www.boost.org/ which implements a dynamic_bitset class which supports the lessThan comparison.
They use a method that is close to your sample except that they work on a higher lever (unsigned longs?), not bits which is certainly faster (about 32 times faster  ).
I'm not keen about using the whole lib just for this class, so I will try to dig in the STL source code in order to implement something similar.
Thanks for the idea.

Ok. In the Visual C++ version of STL, there is a undocumented public direct access on the "unsigned longs" that compose the actual bitfield of bitset.
That is the _W(_I) function which we can use to compare two bitset. Here is the struct that compares two bitset. Not fully tested yet but that gives an idea.
template<size_t _n=""> struct LessThanBitset
{
bool operator()(const std::bitset<_N>& bs1, const std::bitset<_N>& bs2) const
{
typedef unsigned long _Ty;
enum
{
_Nb = CHAR_BIT * sizeof (_Ty),
_Nw = _N == 0 ? 0 : (_N - 1) / _Nb
};
// Since we are storing the most significant bit
// at pos == size() - 1, we need to do the memcmp in reverse.
// Compare a block at a time
for (int _I = _Nw; 0<_I ; --_I)
if (bs1._W(_I) < bs2._W(_I)) return true;
else if (bs1._W(_I) > bs2._W(_I)) return false;
return (bs1._W(0) < bs2._W(0));
}
};

Using the library in this case isn't too painful - most of Boost is like some bits of the STL - you pull in the header file and thats all - for this class, there'll be no object to link in, no DLL to use or anything....go on, do it, you know you want to
In fact, looking at the Boost build files, only these libraries seem to have external code to be built and linked in:
Boost.DateTime
Boost.Regex
Boost.Signals
Boost.Graph
Boost.Python
Boost.Thread
Boost.Filesystem

I have to continue an ATL COM project, wrote by a lazy fellow until now. The problem is that everything compiles ok but when i want to make a change in the IDL - add a method to an interface for example - it still compiles fine, the TLB file is also fine and the DLL looks like nothing happened
It seems that the changes affect anything in the project but the DLL. Have you seen this problem before?

First of all, if you change an IDL file, it's going to update these files :
- the .TLB file itself
- in case options are on, the *_h.h, *_i.c files are updated too.
There's nothing wrong with the fact that the DLL is not changed, as long as the .TLB file is not explicitely added to the .rc resource file.
After all, by default, a type-library lives as a separate file.

Indeed, the cretin had change the TLB file's directory and the DLL remained linked to the old one.
Thank you for the reply
