How to get a Copying Files Dialog in Drag and Drop Matt Bauer22-Sep-03 15:31 Matt Bauer 22-Sep-03 15:31  Question: Is it possible to implement Drag & Drop so that Windows (shell) will create a "Copying" files progress dialog during the drop operation? I have an MFC application that implements asynchronous OLE drag and drop between a TreeView and Windows Explorer using CFSTR_FILECONTENTS/CFSTR_FILEDESCRIPTOR clipboard formats. With synchronous drag and drop, an hour glass cursor is displayed ... with asynchronous drag and drop, no feedback at all is provided via the cursor (I believe). It is desired to display a "Copying files" progress dialog indicating the status of the copying operation when my application is the DragSource and Windows Explorer is the DropTarget. Can anyone point me in the correct direction to get Windows to display this dialog when it is the drop target? Does it require additional clipboard formats? Does it require delayed rendering? Does it require a shell extension? Any help would be greatly appreciated 'cause I am stumped. Thanks. - matt Re: How to get a Copying Files Dialog in Drag and Drop David Crow23-Sep-03 3:18 David Crow 23-Sep-03 3:18  You'll need to supply your own dialog, and have it display the filecopy.avi file.

Re: How to get a Copying Files Dialog in Drag and Drop Matt Bauer23-Sep-03 12:33 Matt Bauer 23-Sep-03 12:33  Thanks David ... I was afraid of that I assume I would instantiate this dialog from my IDataObject object when the target asks for the data. Right? Thanks again. Re: How to get a Copying Files Dialog in Drag and Drop David Crow24-Sep-03 2:33 David Crow 24-Sep-03 2:33  Yes, if that is when the copying begins. Five birds are sitting on a fence.

WinAPI call for CPU/memory usage? gautamcode22-Sep-03 15:27 gautamcode 22-Sep-03 15:27  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. Re: WinAPI call for CPU/memory usage? Matt Bauer22-Sep-03 15:48 Matt Bauer 22-Sep-03 15:48  Not sure about CPU usage but I believe you can get memory usage via PSAPI (on NT). http://msdn.microsoft.com/library/default.asp?url=/library/en-us/perfmon/base/using_psapi.asp Hope that helps. Matt Re: WinAPI call for CPU/memory usage? gautamcode22-Sep-03 16:34 gautamcode 22-Sep-03 16:34  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. Re: WinAPI call for CPU/memory usage? David Crow23-Sep-03 3:21 David Crow 23-Sep-03 3:21  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. Five birds are sitting on a fence. Three of them decide to fly off.

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?

They should know. However, there are some updates on the msdn.com site. May be these patches work. Re: 2002 vs 2003 Link Problems Jeryth23-Sep-03 16:58 Jeryth 23-Sep-03 16:58  Specifics of the error: LNK1104: cannot open file "libci.lib" Any ideas? Always Fear the Man with Nothing to Lose Jeryth Re: 2002 vs 2003 Link Problems Jeryth30-Sep-03 10:28 Jeryth 30-Sep-03 10:28  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. Always Fear the Man with Nothing to Lose Jeryth C++ Library Question. WREY22-Sep-03 12:24 WREY 22-Sep-03 12:24  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. William Fortes in fide et opere! Re: C++ Library Question. Terry O'Nolley22-Sep-03 12:31 Terry O'Nolley 22-Sep-03 12:31  If you begin with a bitset class, you can use bitset::to_ulong and then cast the ulong as a char for display. Re: C++ Library Question. WREY22-Sep-03 12:54 WREY 22-Sep-03 12:54  Thanks for replying. Your suggestion worked very well. Thanks! William Fortes in fide et opere! Re: C++ Library Question. ASchunk22-Sep-03 13:10 ASchunk 22-Sep-03 13:10  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. Regards. Alex Re: C++ Library Question. WREY22-Sep-03 18:24 WREY 22-Sep-03 18:24  Thanks for replying. An earlier response has already pointed me in the right direction which wasn't too far from what your suggestion offered. I knew of "to_ulong()" and have used it several times before, but it only seemed to take the binary representation and return its numeric equivalent, not an alphabetic value if the binary representation it was given, were for such a value. Thanks anyway for replying. I appreciate it. William Fortes in fide et opere! Modeless Dlg gives CView a Variable Schniddel22-Sep-03 12:04 Schniddel 22-Sep-03 12:04  Hi I have a modeless Dialog in my MDI App and now when you click on a button, the modeless dialog should give the view value. but that didnt work. how can I realize this? thx LINK2001 Error TRiegler22-Sep-03 11:47 TRiegler 22-Sep-03 11:47  I wrote an application that directly communicates with external equipment via RS-232 and the like. It also communicates to the sound card as well. Originally the program was written in VB/VC++. I just finished porting the major sections of the program to C# and now it's slow as slow can be. The calls to the external equipment are made using PInvoke to directly call the Win32API. In an effort to speed things up, I'm removing the PInvoke code and replacing it with MC++. However, when I try to call regular C-style DLL files I get a linker error LINK2001 with a mangled version of the original function. The top of the header file has EXTERN "C." My question is: what else can cause this? I'm pretty sure it's a simple fix, but don't know if the MC++ settings are significantly different than the VC++ 6.0.
