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. They should know.
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.

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.

Thanks for replying. Your suggestion worked very well.
Thanks!

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.

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.

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.

Is there any way to get SpinBox Up state?

I was talking the ButtonUp Event for SpinBox.

Assuming you want to know when the Up part of the spin box control has been clicked, the control sends a WM_NOTIFY message with the UDN_DELTAPOS code to its parent window.

I have an Dialog based project and if I try to add a windows messgaehandler for WM_GETMINMAXINFO, I have to change the filter from dialog to window in order to have that message available in the list. Is this ok? What is the reason for this?
Thanks,
ns

Hi ns,
You're doing fine. This filter is just an Visual Studio UI thing designed to minimize the number of handlers the programmer is exposed to, so that only the most commonly used are displayed. Sometimes it happens (as in your case) that you go nuts looking for that handler and it appears nowhere. IMHO the filter thing does more harm than good, and it's badly implemented (it appears in a different tab than where its effect is apparent.)

Good to hear from you again!! Appreciate the quick response.
Thanks,

Hi,
the reason is that the WM_GETMINMAXINFO is usually only avaiable for Windows. The Visual C++ help index says that this handler fills an array with information of the window. However, since dialogs are considered as a window this seems to be corrected.
Kindly yours.

Hi,
My app minimises to the tray using a kind CP person class. It all works really good but my icon is 256 colors and in the tray it looks like it is 16 colours and does not look very good. Can I show it in 256 colors in the system tray or not?
Thank you.

Be sure you don't have a 16 color icon as well.

I definitely have not. I have two 256 color icons. I have just now put a 16 color icon in to see if it will use the 16 color one I made which does not look as bad as the one it displays in the tray. I think that perhaps the tray icons are not even 4 bit (16)color.
I can not find anything in MSDN about this problem.

To avoid icon distortion, be aware that notification area icons have different levels of support under different versions of Microsoft Windows. Windows 95, Windows 98, and Microsoft Windows NT 4.0 support icons of up to 4 bits per pixel (BPP). Windows Millennium Edition (Windows Me) and Windows 2000 support icons of a color depth up to the current display mode. Windows XP supports icons of up to 32 BPP.

Thank you.
I have read it and what it says about Windows 2000 is strange because I am running Windows 2000 and I get icon distortion. My icons are definite 256 colors and my display mode is definite 32 bit mode.
I wonder what is happening?
