Re: How to get a Copying Files Dialog in Drag and Drop

You'll need to supply your own dialog, and have it display the filecopy.avi file.

Thanks David ... I was afraid of that Wink | ;-)

I assume I would instantiate this dialog from my IDataObject object when the target asks for the data. Right?

Thanks again.

WinAPI call for CPU/memory usage?

24-Sep-03 2:33

Yes, if that is when the copying begins.

Hello,
I want to know if there is a WinAPI call ( or some other mechanism ) for getting the CPU and memory usage information from the system? The ideal solution would be to get the above information on a per process basis. Could somebody help me out????

Thanks & Regards,
Gautam.

Not sure about CPU usage but I believe you can get memory usage via PSAPI (on NT).

Hope that helps.

Thanks Matt,
I just found out that it is possible to secure system-wide performance data by accessing the Win32 registry key HKEY_PERFORMANCE_DATA. I have a feeling that this is used by the friendly Task Manager! So, I would be able to retrieve all the information I am looking for (hopefully!). Here is the link to the related MSDN article:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfMicrosoftWin32RegistryClassPerformanceDataTopic.asp[^]

Thanks again for your help.

Best Regards,
Gautam.

I like that second paragraph:

Although you use the registry to collect performance data, the data is not stored in the registry database. Instead, accessing the registry with this key causes the system to collect the data from the appropriate system object managers.

Hi there,
I wrote How to get CPU usage by performance counters (without PDH)
which applies to Windows NT, Win2K/XP.
Try it.

So I'm trying to learn DirectX and got a book to do so ( pause here for laughter ) but I'm having a bit of trouble. The book teaches DX 8.1 and requires VC .NET 2002. I've got .NET 2003 and keep getting link errors saying some library can't be opened. A quick search of my HDD showed that it's there where it ought to be and I can open it fine. My include directories, library dependencies are set correctly, and the DX 8.1 SDK is installed to default paths. Even when I open the solutions directly from the indluded CD I get the same link errors. Is there some discrepancy between 2002 & 2003 or is it something else?

Hi,

you got only one chance left. Contact the Microsoft people. Cool | :cool:

They should know. Roll eyes | :rolleyes:

However, there are some updates on the msdn.com site.
May be these patches work.

Specifics of the error: LNK1104: cannot open file "libci.lib"

Any ideas?

Hmm, I'm replying more to my own question.

I have found the problem, the libci,lib file is in the wrong spot somehow. I think it might have something to do with having VS 6.0 installed simultaneously w/ .NET I moved the library to a different folder and explicity listed that dir as an additional lib folder and the lining went fine. Could any of you do a search and find where the library is on your machines? Thanks.

C++ Library Question.

The library member, <bitset> allows one to do the following:

cout<<bitset<8>('A') <<endl;

and see the binary representation of "A" displayed.

It doesn't look as though the library offers a means to reverse the transformation, where if you were to give the binary representation, you'd get back the ASCII equivalent.

Does anyone know of such a way?

Thanks for any suggestion.

If you begin with a bitset class, you can use bitset::to_ulong and then cast the ulong as a char for display.

Hi,

there is a function called to_ulong() defined in the bitset header file which is the counterfunction to to_string() which turns a string into a binary value.
Hope it helps.
