Looking at PERF_DATA_BLOCK in MSDN, it says 'Header: Declared in Winperf.h; include Windows.h.'.
You have included Windows.h, which makes me suspect there's a macro getting in the way. Looking at Windows.h, it won't include WinPerf.h if the macro WIN32_LEAN_AND_MEAN is defined - I seem to remember that an auto-generated stdafx.h does define WIN32_LEAN_AND_MEAN. Check for that.
PS - I compiled this code successfully (just these two lines) using the command-line C++ compiler, which says that there must be something in your setup or software that's stopping PPERF_DATA_BLOCK being defined.
#include <Windows.h>
PPERF_DATA_BLOCK p = new PERF_DATA_BLOCK;

Hi Savitri,
Use CoCreateInstance to co-create your component. Once you get the interface pointer, you can call its functions.
Finally, don't forget to release the component after you finish your work.
See the help on CoCreateInstance and Release in MSDN  .

Hoe to retrive the html text box input using IHTMLElemt interface.

innerText property [^] looks promising. See also [^].
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

The docs says:
Most Boost libraries are header-only
So does it compiles very slow?
And any way to make it fast?
|
|
|
|
|
Boost libraries will slow down compilation, mainly due to the amount of code in the headers and the number of template instantiations needed. To speed it up, include Boost headers into a pre-compiled header. But not Boost.Bind or Boost.Lambda headers, as they use declare some objects that need to be single instance, and putting them in pre-compiled headers can mess that up.
You need to balance the convenience that Boost headers get you against the compile times. It's worth it 99% of the time.

I can't understand why it is worth. 99% of the time when using boost, I think the document should be enough, is it?

Huh?

Thanks for you help.
But I can't agree that header files contains so much implementations code, I think it will slow down the compilation a lot (not sure). Could you tell what's the benifit by doing so?
|
|
|
|

I still don't understand what your asking. Boost relies heavily on templates, which can tend to slow down compilation. The solution, as previously mentioned, is to use pre-compiled headers.

Template code *has* to be in headers if you're going to instantiate it for different template parameters, because every time you instantiate, you create a new implementation of the class/function.

If it is, where can I find it?
Thanks.

Not open as such, but it gets installed with versions of Visual Studio you pay for. In my VS2008 installation, it's in C:\Program Files\Microsoft Visual Studio 9.0\VC\crt\src.
|
|
|
|

Actually is should be here (along with other things): "C:\Program Files\Microsoft Visual Studio 9.0\VC\include". The CRT and the STL are two different things.
Steve
|
|
|
|
|
Call it a tie - we're both correct. Yes, CRT and STL are different, and yes, the include directory has most of the STL, but there's a reasonable amount of it that's in the crt/src directory as well (mostly code that's common across all template instantiations and pre-instantiated items like std::string (==std::basic_string<char>) and the streams.

I had problem in migrating from VC6 to VC2005
typedef _A::size_type size_type; works fine in the vc 6 and flashes the below error after migrating to VC 2005
"thirdparty\dinkumpatches\xstring(39) : error C2146: syntax error : missing ';' before identifier 'size_type'"
pls advice
|
|
|
|

it looks like the "_A" isnt defined. Look where it was defined in the VC6 and than you why it isnt defined in VS2005. I guess it is a define which surrounds the "_A".  Bad code
