Raw speed. The compiler would do the mapping for you, yielding a constant time complexity at runtime.
Of course, you'd only be able to make static mappings, such mappings that the compiler can resolve.

So, then, how is it better than declaring a const int or even a define ? All you're asking is for the compiler to substitute a name known at compile time with a number known at compile time, right ?

Flexibility and type safety. Think of macros on steroids.

Hi Friends,
Thanks for the idea, something like this works for me
extern char str[] = "str1";
extern char str2[] = "str2";
template <const char* str>
struct xyz
{
xyz() { }
operator int()
{
return 0;
}
};
template <>
struct xyz<str>
{
xyz() { }
operator int()
{
return 10;
}
};
template <>
struct xyz<str2>
{
xyz() { }
operator int()
{
return 20;
}
};
int main()
{
int value1 = xyz<str>();
int value2 = xyz<str2>();
return 0;
}
Here value1 will have a value = 10 and
value 2 will have value = 20 after initialization.
May be this is a crude way of doing things but I wanted to find out if it can be done.
Thanks once again

Hi,
I'm trying to debug an ATL Server project and when I try attach to the dllhost process an "Access Denied" error appears. I'm using Visual Studio 2003 and Windows 2000 SP4. I've been looking in the internet for two days and I've tried all that I found about this topic (I checked the impesonation and the debug programs policies, the "Machine Debugger Manager" service, I verified that I was in the local "Administrators" group, the security of the directories where my DLLs are). I can't find anything else to verify. I would really appreciate if somebody can help me in any way, at least telling me what else could I check.
Thanks,
Federico

Hello,
I have a monochrome watermark bitmap, which I'd like to render over
COLOR_WINDOW. How to calculate the color to render it?
I'd like it to be lighter than COLOR_WINDOW if the one is dark and I like it
to be more dark than COLOR_WINDOW if the one is light (for example, white).
Thank you, I'm really apreciating any suggestions.

Define some areas of your window that will have these effects. Handle the WM_NCHITTEST message. If the area is hit, return HTCLOSE or HTMINBUTTON as appropriate. Otherwise pass the message down to DefWindowProc.

How to convert integer to string in ATL?
rajesh
|
|
|
|
|
Which ATL? If it's ATL 7 (i.e. the one that VS.NET), you can use CString::Format. If you're using ATL 3 (i.e. the one with VS6), then you're probably best off using itoa - just make sure your string buffer is big enough!

Try this:
string itos(int i)
{
stringstream s;
s << i;
return s.str();
}
You'll need to include sstream as well.
CString::Format also works as the other poster says - if in ATL 7.

What String format are your Taking mr Rajesh i.e. BSTR,wchar_t or simple char*.
anyway here is example of each,as TCHAR is defined as
#ifdef UNICODE
#define TCHAR wchar_t
#else
#define TCHAR char
#endif
so for converting intger to string i will use _itot(..)
let integer i=20;
TCHAR IntStr[10];
_itot(i,IntStr,10);

How does one convert from ATL::CString into a std::string?
I am the handsome one in the crowd.

CString source = "CodeProject";
std::string destination;
destination = (LPCTSTR)source;

Hi
I have two CTreeViewCtrl on two different property pages that represent the same data. One of them is read-only, however with the other one you can add/update or delete nodes and leaves in the tree.
At the moment changes made in one is not shown in the other, and creating inconsistencies in the UI.
What is the recommended practice to propagate changes made in the editable page to the read-only page? Do I have to code it manually using an Observer type pattern or is there a built in WTL way?
Thanks

I'm developing IE toolbar. Everything was just fine, but now, when the toolbar is done I cann't turn on XP theme for it 
I have added this to my resource file:
CREATEPROCESS_MANIFEST_RESOURCE_ID RT_MANIFEST toolbar.manifest
Here is my "toolbar.manifest" file:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity
name="Microsoft.Windows.InstallMaker"
processorArchitecture="x86"
version="1.0.0.0"
type="win32"/>
<description>Install Maker</description>
<dependency>
<dependentAssembly>
<assemblyIdentity
type="win32"
name="Microsoft.Windows.Common-Controls"
version="6.0.0.0"
processorArchitecture="x86"
publicKeyToken="6595b64144ccf1df"
language="*"
/>
</dependentAssembly>
</dependency>
</assembly>
I have no any idea where is the problem.
Thanks.

That's the wrong resource ID. CREATEPROCESS_MANIFEST_RESOURCE_ID is used for EXEs, for DLLs use an ID of 2.
